Abstract

The separator has a separating base (3) in the vessel (1), at an angle to the horizontal. In the sludge trap chamber (5) it defines a sludge sump at an acute downwards angle and a floating matter collection zone at an acute upwards angle. A sludge takeoff (17) is at the lowest point of the sludge trap chamber, and the floating matter takeoff (21) is at the highest point of the separation chamber. The separation chamber (7) is operated without a free level. The sludge takeoff (17) is located at a point one-quarter of the vessel (1) height, and the grease takeoff (21) is at three-quarters of the vessel height. The separation base (3) acts as a heat exchange surface between the sludge trap chamber (5) and the separation chamber. An air bleed (23) is at the highest point of the separation chamber so that the vessel can be totally filled during operation without a free level. The connecting channel (19) in the separation chamber has an opening (19a) which is aligned upwards. The apparatus, when structured to separate grease, has a heating system at least at the upper section of the separating base and/or at the takeoff for the light matter, to heat and liquefy the floating grease. A trough, with an overflow weir, can be in front of the clean water takeoff (27). The overflow edge for the floating matter is structured and heated so that the light material can flow constantly over it. A grease collection chamber has an air bleed valve which, when closed, has a hollow and air-filled zone under it. When the valve is opened, any grease under the air zone floats upwards into the hollow section. The sludge trap chamber is linked to a sludge collection chamber with an air bleed valve. When the valve is closed, an air-filled zone is formed under it. When the valve is opened, the contents under the air space can move into it. A separator apparatus for starch, after a sludge trap, has a separation vessel divided by a separating base into an upper sludge trap chamber and a lower separation chamber. The sludge trap chamber has an inlet (13) for the water to be cleaned, and the separation chamber has an outlet for the clean water with an overflow edge. A connecting channel is between the sludge trap chamber and the separation chamber, with an overflow in the sludge trap chamber. The separating base is angled against the horizontal, and defines a sludge sump at an acute downwards angle. A sludge takeoff is at the lowest point of the sludge trap chamber, and a starch takeoff is at the lowest point of the separation chamber.

The grease separator shown in FIGS. 1-3 for separation of fresh fat, e.g. B. from waste water from commercial kitchens or the like, consists of a separating tank 1 in the form of an upright, circular cylinder, the through an inclined partition 3 into an upper sludge trap chamber 5 and a lower separation chamber 7 divided is. The partition 3 is flat and can be vertical Axis of the container 1 an inclination z. B. in the area from 30 ° to 60 °, preferably an inclination of approximately 45 °. The sludge trap chamber 5 is through an inspection opening 9 accessible with cover in the upper container wall, access to the deposition chamber 7 enables lateral inspection opening 11 with cover in the peripheral wall of the container.

In the sludge trap chamber 5 opens at its upper end Inlet 13 for the waste water or for the liquid mixture to be separated. The inlet 13 is a baffle 15 for Subsequent flow calming. The contained in the wastewater Sediments settle as mud on the top of the partition 3 and slide along this down to the bottom of the sludge trap chamber 5, the forms a sludge sump that tapers downwards the lowest point of a mud vent 17 with a closure member is arranged.

A connecting tube 19 is arranged in the container 1, that connects the sludge trap chamber 5 to the separation chamber 7 and penetrates the partition 3. The upper confluence the connecting tube 19 is preferably located near the axis Area of the separation chamber 7 and at such a distance under the free water level in the mud trap 5, that the flowing down in the connecting tube 19 Water creates a suction that is already floating Greases in the sludge trap 1 entrained. How 1, the connecting pipe 19 runs slanted downwards towards a near the peripheral wall lying position. There is at the bottom of the Connecting pipe 19 a pipe socket 19a attached, the approximately in the tangential direction and with one pointing upwards Inclination runs out of the sludge trap 5 through the connecting pipe 19 into the separation chamber 7 flowing liquid mixture with a tangential and upward movement component into the separation chamber 7 occurs. Separate in the separation chamber the specifically lighter substances, especially fat, from the water and collect in the upper area of the separation chamber 7 below the partition 3, the one forms a tapered light-weight collecting space. At its highest point is a grease trigger 21 with shut-off device provided by which the separated fat is withdrawn and Z. B. be collected in a collecting container can. The fat deduction 21 is also schematic with a shown vent 23, which ensures that the separation chamber 7 always completely without a free mirror is filled to its highest point.

For the removal of the pure water from the separation chamber 7 serves a riser 25, which is at least approximately perpendicular runs within the container 1, from the lower region of the Separation chamber 7 goes out, penetrates the partition 3 and at the upper end with a branch pipe branching off to the side 27 for the pure water is connected.

The bottom 29 of the deposition chamber 7 is slightly against the horizontal inclined, and at the lowest point of the deposition chamber 7 an emptying connection 31 with a shut-off device is arranged, to empty the entire separator. The separator tank 1 can on the (not shown) foundation at the lowest point of its bottom 29 and with two additional provided legs 33 to be supported. Underneath the ground can be arranged a vibration exciter 35, the separator can vibrate to detach from Suspended substances or light substances from the walls of the separator tank to favor.

The separator shown in Figs. 1-3 offers a special simple, inexpensive and space-saving design the following operational advantages: d. H. the sediments from the upper sludge trap and the light materials from the lower separation chamber through the specified hydrostatic pressure conditions removed and z. B. withdrawn into barrels without an additional pressure increase for this removal process (e.g. using a hand pump, generating a jam in the Clean water drain etc.) is required. That at the Bottom of the separating plate 3 grease protrudes the partition 3 in thermal contact with the incoming wastewater in the sludge trap chamber 5. Since the incoming wastewater, e.g. B. from commercial kitchens and similar companies, as a rule inflows with increased temperature, it contributes to the Grease at the bottom of the partition 3 to heat and in maintain a liquid, deductible state. An additional It is therefore not necessary to heat the light materials, can also be provided if necessary. For example, the partition 3 can be designed as a double wall inside of which there is a heated liquid, e.g. B. heating water or electrically heated carrier oil, circulates.

The embodiment of the fat separator shown in FIGS. 4-6 largely corresponds to that according to FIGS. 1-3 with the exception that the separator tank 41 has none round but rectangular plan. A level mezzanine 43, the separator tank 41 in the upper Sludge trap chamber 5 and the lower separation chamber 7 separates, is installed so that it is parallel to the narrow sides of the separator tank 41 an inclination of approx. 30 ° (Fig. 5) and also parallel to the long sides the separating tank 41 has an inclination of z. B. about 10 ° (Fig. 4), so that it is in the direction of its greatest gradient is inclined by approx. 40 ° to the horizontal. The rest Devices of the separator are designed analogously as in the embodiment of FIGS. 1-3 and are therefore also designated with the same reference numerals. The Inlet 13 with a downstream baffle 15, the pure water outlet 27 and the mud vent 17 are all on the same Narrow side 45 of the separating container 41 is arranged (cf. Fig. 4 and Fig. 6) while on the opposite Narrow side 47 only the grease trigger 21 with ventilation 23 the highest point below the intermediate floor 43 is. Extends near this narrow side wall 47 the connecting pipe 19, which the sludge trap 5 with the Separation chamber 7 connects, vertically downwards. With the Embodiment according to FIGS. 4-6 are similarly simpler, affordable, robust and space-saving design achieved the same operational advantages as the Embodiment according to FIGS. 1-3.

The embodiment of the fat separator shown in FIGS. 7-9 corresponds in construction to that of FIGS. 1-3. The corresponding components have the same reference numerals provided and will not be discussed in more detail below explained. The embodiment according to FIGS. 7-9 is however additionally provided with an emptying and rinsing device. The outgoing from the lowest point of the deposition chamber 7 Drain port 31 is on the suction side Pump 51 connected, the pressure side via selective controllable valves 53, 55 optionally with an emptying riser 57 or connectable with two rinsing tubes 59, 61 is. One flushing pipe 59 runs on the outside of the Separation tank 1 upwards, then with a horizontal one Section 59a into the interior of the separating container 1 and ends up with an upward mouth a beam splitter 63 for generating one radially after all Sides of the flat jet emerging when the separating tank is full 1 brushed the water surface and at increasing emptying the inner walls of the sludge trap 5 rinses off. The other flushing pipe 61 runs from the shut-off element 53 obliquely upwards into the interior of the separation chamber 7 and ends in a beam distributor 65, which is close to the bottom of the partition 3 is arranged and one this bottom surface can produce a flat jet.

If the separation container 1 is to be emptied, the first step is the shut-off device 55 for the drain pipe 57 closed and the shut-off device 53 to the flushing pipes 59, 61 open. The pump 51 is started up so that Pumped water out of the drain port 31 and over the rinsing pipes 59, 61 into the sludge trap chamber 5 and the separation chamber 7 is pumped back, creating a vigorous Circulation and mixing of the separator content and at the same time rinsing of the inner walls via the jet distributors 63, 65 and in particular the underside of the partition 3 is effected. After a sufficient rinsing process, the shut-off device 53 closed and the unlocking device 55 opened, so that now the entire separation content from the drain connection 31 pumped out and over the drain pipe 57 z. B. in a connected transport vehicle is pumped away. For a subsequent refilling of the An additional filling connection 67 can be provided in the separator his.

When emptying the separator it is important that too the content of the upper sludge trap chamber 5 does not have the Sludge discharge 17, but via the drain port 31 is subtracted. To this end, the deepest area of the Partition 3 provided an opening with a closure member 69, which is shown on a larger scale in FIG. 8A and Z. B. can be designed as a float valve. As long as the lower separation compartment 7 is filled Float flap 69 closed. If the separation chamber 7 drained via the drain connection 31 and the pump 51, so the float flap 69 opens, so that the content the sludge trap chamber 5 through the opening in the partition 3 flow into the separation chamber 7 and via the drain connection 31 can be pumped out.

8B shows an alternative embodiment in which the Closure member as a float ball 71 with associated ball cage 73 is formed.

10-12 show an embodiment of the separator, intended for the separation of starch from waste water is. The design largely corresponds to that of Fig. 1 - 3, and corresponding parts have the same reference numerals as shown in Figs. 1-3. The round separator tank 1 is inclined by approx. 45 ° Partition 3 in the upper sludge trap chamber 1 and the lower Separation chamber 7 divided. The separation chamber 7 serves in this case not to separate from floating Lightweight, but for separating strength, the heavier is as water. That is why it is at the top the separation chamber 7 only the vent 23, but no exhaust line. Which are on the inclined bottom 29 of the separation chamber 7 settling starch is withdrawn via the deduction 31 and can e.g. B. filled into barrels or a recycling be fed. In the sludge trap chamber 5 sits up 3 sludge mixed with the top of the divider Starch from which can be removed via the mud vent 17 can. The wastewater inlet 13 is a collecting basket or bucket 37 subordinate to catch coarse impurities. For better Allowing access to the grass catcher 37 is the upper inspection opening 9 eccentric to the axis of the separating tank 1 arranged. The same applies to all other parts given with reference to FIGS. 1-3.

The separator shown in Figs. 13-15 is a gasoline separator, its basic construction in turn with the according Fig. 1 - 3 matches and so far with the same reference numerals is provided. That via the inlet 13 with a downstream Baffle 15 tapered, contaminated with gasoline Waste water enters the sludge trap chamber 5, where the sediments on the top of the inclined partition 3 settle and at the deepest point of the sludge trap 5 can be deducted on the mud vent 17. Near the water level in the sludge trap chamber 5, the height of which the height of the pure water drain 27 is set, the flows Water into the inlet opening of the connecting pipe 19, wherein Light fabrics are carried away and reach the lower one Separation chamber 7, where the gasoline or other light materials float to the bottom of the divider 3 accumulate and at the highest point of the separation chamber 7 deducted over the gas vent 21 provided with vent 23 can be.

In contrast to the embodiment according to FIGS. 1-3, it runs the riser 25 of the pure water drain 27 outside the separator tank 1 and is with one in the center of the floor 29 of the separation chamber 7 arranged, vertically upwards Directed drain connector 39 connected. The top of the Drain connector 39 is a valve seat for a float valve 75 formed, which is guided in a cage 77 and whose float 79 on the density difference between gasoline and water is balanced, so that the float valve 75 closes the drain port 39 when the under the separating floor 3 accumulating separated gasoline layer has reached a predetermined layer thickness.

The embodiment of the separator shown in Figs. 16-18 largely agrees with that of FIGS. 13-15 match and is so far provided with the same reference numerals. The separator according to FIGS. 16-18 is an oil separator trained and is also in the sludge trap chamber 5th provided with a coalescence filter 81, which the inlet of the leading from the sludge trap chamber 5 to the separation chamber 7 Connection tube 19 is connected upstream. The coalescence filter 81 consists of a variety of horizontal, at spaced filter mats 83, the arranged in a tubular housing open at the top are, which with the upper end of the connecting tube 19th connected is. That from the free water level in the sludge trap 5 water flowing into the coalescence filter 81 must flow through the coalescing filter mats 83 before it passes through the connecting pipe 19 into the separation chamber 7, where there is oil or other light materials accumulate on the underside of the partition 3 and on the highest point are deducted by the oil drain 21 can.

A modified embodiment of the separator according to Fig. 16-18 is only shown in section in FIG. 19. It makes a difference different from the previous embodiment only by the design of the coalescence filter 81 ', which in this Case is designed as a ring filter, with a cylindrical Coalescing filter medium 83 by a support basket is worn, and upper and lower, waterproof End walls 85, 87. Water from the sludge trap 5 must flow through the coalescing filter medium 83 before it from above into the connecting pipe 19 and through this into the Separation chamber 7 can flow. Regarding all the usual ones Details are referred to the description of FIGS. 16-18.

The schematically shown in Fig. 20 in side view Embodiment of the separator according to the invention is correct, as far as the actual separation container 1 is concerned, largely with the embodiment shown in Figs. 1-3 match. The same reference numerals are therefore used as in Fig. 1-3 used, and for the detailed description to the description of FIGS. 1-3. Below only the details deviating from FIGS. 1-3 are described.

A level compensation channel 89 is known to the inlet 13 Design assigned to the maintenance of a possible constant water level 91 in the sludge trap chamber 5 ensures, and thus constant running-in conditions in the upper opening of the connecting pipe leading to the separation chamber 7 19. The clear water flows over a long time Weir edge 105 into the ring gutter, so that inlet impacts are intercepted and only to slight fluctuations in level 91 to lead.

The one arranged at the lowest point of the inclined partition 3 Sludge discharge 17 is via a gate valve 93, a releasable coupling 95 and a flexible connecting piece 97 connected to a sludge collecting container 99, at appropriate intervals from the sludge trap chamber 5 withdrawn sludge, so that the volume of the Sludge trap 5 largely for the separation process remains available. One from the sludge collector 99 after The leading nozzle is with a vent valve 101 Mistake. Furthermore, the sludge collecting container 99 has a bottom Drain connection 103 with shut-off device to the e.g. B. the suction hose of a disposal vehicle Pump can be connected.

The sludge collection tank 99 has under the vent valve 101 a cavity 101A, in which when closed Valve 101 is air. After opening the valve can the sludge or residual water in the cavity rise the cavity. When changing the container nevertheless no sludge or residual water spilled.

From the separation chamber 7 leads inside the separation container 1, the riser 25 to the pure water drain 27, which the Overflow weir 105 is upstream.

At the highest point of the separation chamber 7 is below the partition 3 of the grease trigger 21 connected as heated tube is formed that up to an overflow edge 107 is pulled up. The overflow edge 107 is at such a height that the fat is due to the Difference in weight compared to water and therefore constantly can expire. The overflow edge is the one in front of it Heated fat area. About the Grease overflowing edge 107 enters a grease drain pipe 109, which is preferably completely or partially transparent is to be able to observe the flow of the fat. Via a gate valve 111 and a flexible connection 113 is the fat drain pipe 109 with a fat collecting container 115 connected to a vent 117 and a drain outlet 119 near the floor, each with shut-off device, is provided.

There is also a below the vent valve 117 Cavity, corresponding to cavity 101A, in the open state Valve 117 grease can enter, so that from the Swap body no grease escapes when the clutch is released becomes.

The uppermost region of the dividing plate adjacent to the fat deduction 21 3 is designed as a heatable surface 121, so that the separated fat in this area in a deductible, can be kept in a liquid state. That too is the fat loss 21 forming exhaust pipe and the overflow edge 7 are provided with suitable heating devices, such as. B. at 123 indicated. This way, a continuous Out of the fat kept liquid by heating the separation chamber 7 via the exhaust pipe 21, the overflow edge 107 and the fat drain pipe 109 in the fat collection container 115 into it, under the hydrostatic Pressure of the water volume in the separating tank 1, whose mirror height 91 through the inlet 13th assigned overflow edge 89 is set.

The bottom 29 of the separation chamber 7 is funnel-shaped, so that the drain port 31 (with a shutoff device) (not shown) at the lowest point of the Riser 25 is located. Furthermore, the vent nozzle 117 extended as a bridge 118 to the upper separator tank.

In the operation of the separating system, the shut-off device 93 is Sludge collection tank 99 (preferably with a capacity of over 100 liters) always open. The container 99 is filled with water when connected to the nozzle 97, the when sludge flows back into the clear water zone of the Mud trap is displaced. The container 99 is thus part of the sludge trap volume and a sludge thickening occurs in it by the pressure of the water column.

When the container 99 is filled, what on a sight glass can be seen, the shut-off device 93 is closed and that Shut-off device 101 opened. This allows the in the connecting piece 97 existing water residue in the room under the shut-off device 101 flow and runs when the clutch 95 is released not from. The coupling is on the container side with a lid is closed and the vent valve 101 is closed. In this state, the container can be removed and an interchangeable container can be connected.

Figures 21 and 22 show a side view and a top view an installation variant for the separator according to the invention. The separator 1, which is essentially based on FIGS to 3 has been described, is preferred in this installation variant recorded underground in a concrete housing 123 and stands elevated on feet 124. The housing 123 has in the supervision a circular cross-section, and inside of the housing are radially extending partitions 135 and 137 are provided, which are brought together in the middle (cf. Fig. 22) and in height up to just below the bottom edge of the separator 1 extend. This will be sector-shaped Storage compartments 139 and 141 are formed. The Sludge discharge 17 is arranged above the storage compartment 139 and flows into this storage compartment, the fat, Gasoline or oil drain 21 is above the storage compartment 141 arranged and opens into this storage compartment. With the corresponding fume cupboards are connected by a control room from remote controlled so that mud and Fat is released into the corresponding storage compartments in a controlled manner can be. The fill level of the storage compartments will sensed by sensors (not shown). The inflow is connected to a corresponding inlet line 131 and the drain 27 with a corresponding drain line 133.

The container 123 is provided with a lid 127, one Inspection opening 147 and pumping openings 143 and 145 having. The fat collected in the storage compartment 139 is sucked off via the pumping opening 143 and that in the storage compartment 141 collected sludge through opening 145.
