Abstract
Description
Technical Field
[0001] The utility model belongs to the field of catering swill treatment equipment, and particularly relates to a swill grease recovery device. Background Technique
[0002] With the gradual increase of large-scale catering food plazas such as various complexes, enterprise canteens, school canteens, hotels, and food cities, the problem of catering swill grease treatment has become increasingly prominent.
[0003] Catering swill contains a large amount of grease and food residues. If it is directly discharged without separation treatment, on the one hand, it pollutes the environment, blocks pipelines, causing great difficulties in later environmental governance and wasting a lot of manpower and material resources. On the other hand, the direct discharge of grease residues itself is a waste of resources. If the grease residues are classified and recycled. Content of the Utility Model
[0004] A swill grease recovery device of the utility model is used to solve the above problems.
[0005] A swill grease recovery device of the utility model includes a treatment tank and a spiral pusher. One end of the spiral pusher is inside the treatment tank, and the other end is outside the treatment tank; there are leakage holes on the outer shell of the spiral pusher, and the leakage holes are inside the treatment tank. There is a feed inlet on the treatment tank, and food residues can enter the spiral pusher through the feed inlet and the leakage holes in sequence;
[0006] There are several oil discharge holes for discharging the oil and water mixture at the bottom end of the outer shell of the spiral pusher; a liquid collection tank box is fixed at the bottom end of the outer shell of the spiral pusher, and the liquid collection tank box is used to collect the oil and water mixture leaking from the oil discharge holes;
[0007] It further includes an oil-water separation component for separating the oil and water mixture.
[0008] Further, an elbow is fixedly connected to the liquid collection tank box; an external filter for further filtering food residues is fixedly connected to the outer wall of the treatment tank. The oil and water mixture in the liquid collection tank box is connected to the external filter through the elbow, and the external filter is connected to the oil-water separation component through a hose.
[0009] Using the external filter, further filter the food residues in the oil and water mixture, and minimize the food residues entering the oil-water separation component as much as possible. The external filter, compared with placing the filter inside the box, can facilitate people to clean the filtered residues.
[0010] Further, the external filter includes a rectangular box without an upper bottom surface. There are holes for discharging oil and water at the bottom of the rectangular box. A basket is arranged in the rectangular box. The basket has fine holes for the oil and water mixture to pass through, and the basket can be lifted out of the rectangular box.
[0011] The structure is simple, and the food residues filtered by the basket can be cleaned by directly lifting the basket.
[0012] Furthermore, the oil-water separation component includes: an oil-water separation tank; a liquid level sensor and an oil level sensor, which are arranged in the oil-water separation tank, and the oil level sensor is located above the liquid level sensor; an oil drain pump, whose inlet end is at the same height as the oil level sensor, and can extract the oil from the oil-water separation tank separately; a drain valve for draining water from the oil-water separation tank, which is installed on the oil-water separation tank and is located below the liquid level sensor.
[0013] The oil and water can be separated. The oil drain pump and oil level sensor are used to automatically drain the oil from the oil-water separation tank. The liquid level sensor and drain valve can also be used to promptly drain the water from the oil-water separation tank. The reason why the inlet end of the oil drain pump is set at the same height as the oil level sensor is to ensure that only oil is pumped out and prevent water from being drawn into the oil drain pump.
[0014] Furthermore, a heater is provided on the outer wall of the oil-water separation tank, which can heat the oil and water mixture in the oil-water separation tank to prevent grease from condensing.
[0015] It can prevent grease from coagulating and allow the drain pump to extract the uncoagulated grease from the oil-water separation tank.
[0016] Furthermore, an oil collecting barrel is placed in the processing box, and a weighing module for monitoring the weight of the oil in the oil collecting barrel is also placed in the processing box. The oil collecting barrel is placed on the weighing module, and the oil drain pump on the oil-water separation component can draw the oil in the oil-water separation component into the oil collecting barrel separately.
[0017] Quantitatively remind relevant personnel to dispose of the grease in the oil collection barrel in time and replace the empty oil collection barrel. Beneficial effects
[0018] A spiral pusher is used to transport food residues from one end to the other. Since the spiral pusher squeezes the food residues during the transportation process, the oil in the food residues is squeezed out, and the squeezed oil is discharged from the spiral pusher through the oil drain hole.
[0019] A flushing joint is provided, through which clean water can flow out and enter the screw pusher. The clean water flushes the grease on the food residue. When the oil in the food residue is squeezed, the oil and water mixture is squeezed out from the food residue, thereby achieving the purpose of further grease separation from the food residue.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.
[0025] See Figure 1 , a swill oil recovery device, comprising a processing tank 1; a screw pusher 2 is fixedly installed on the processing tank 1. The screw pusher 2 belongs to the prior art and is composed of a screw blade welded on a shaft and a housing, and the housing is fixedly connected to the inner wall of the processing tank 1. By driving the shaft and the screw blade to rotate as a whole by a motor, it can make the food residues move from one end of the shaft to the other end. In this embodiment, the motor is a low-power brushless motor.
[0026] In this embodiment, viewed from Figure 1 this perspective, the screw pusher 2 is inclined, with the left end of the screw pusher 2 being lower and the right end being higher. The screw pusher 2 conveys the swill from its left end to the right end. The left end of the screw pusher 2 is located in the processing tank 1, and the right end of the screw pusher 2 is outside the processing tank 1. The right end of the screw pusher 2 is provided with a slag outlet.
[0027] See Figure 2 and Figure 3 , a leakage hole 3 is provided at the top of the left end of the housing of the screw pusher 2, and a feeding port 4 is provided at the top of the processing tank 1, and the feeding port 4 is above the leakage hole 3. In this embodiment, the shape of the feeding port 4 is funnel-shaped. The swill is directly poured into the funnel-shaped feeding port 4, and under the action of its own weight, it gathers along the inner wall of the funnel and falls from the bottom of the feeding port 4 to the leakage hole 3, and finally enters the screw pusher 2. The screw blade of the screw pusher 2 rotates, and the screw blade conveys the food residues in the swill from the left end of the screw pusher 2 to the right end of the screw pusher 2. Finally, the food residues are separated from the processing tank 1 at the right end of the screw pusher 2, and the corresponding collection device collects the food residues.
[0028] To facilitate the removal of grease from the swill from food residue, a flushing connector (not shown) is installed at the feed inlet 4. Clean water, in this embodiment tap water, flows out of the flushing connector. The clean water flows along the inner wall of the funnel-shaped feed inlet 4, flowing under its own weight toward the leak hole 3 and ultimately into the auger 2. There, the clean water comes into contact with the swill directly poured into the auger 2, flushing the swill and allowing the grease from the food residue to be easily removed.
[0029] The outer shell of the auger 2 is provided with a plurality of oil drain holes, which are located at the bottom end of the auger 2. The oil drain holes are densely distributed on the outer shell of the auger 2 along the direction of the axis of the auger 2, ensuring that the oil and water mixture at various positions of the auger 2 can be separated from the auger through the oil drain holes.
[0030] During the process of conveying food waste by the screw propeller 2, the grease on the food waste is smoothly separated from the food waste by the aforementioned clean water flushing action. The grease and the wastewater after rinsing the grease together form an oil-water mixture, which can seep downward from the oil drain hole due to its own weight. Note that because the food waste is a solid object, its size is much larger than the oil drain hole, so the food waste will not seep downward from the oil drain hole.
[0031] A sump box 5 is fixedly attached to the bottom of the auger 2 to collect the oil-water mixture leaking from the drain hole. The sump box 5 encloses the drain hole at the bottom of the auger 2's housing, ensuring that any oil-water mixture leaking from the drain hole enters the sump box 5. The sump box 5 is tilted, with the left end lower and the right end higher. Any oil-water mixture that enters the sump box 5 is collected by its own weight at the left end of the sump box 5.
[0032] The left end of the sump box 5 is fixedly connected to an elbow 6, one end of which is in communication with the sump box 5. An external filter 7 is fixedly mounted on the outer wall of the processing box 1, the other end of which is in communication with the external filter 7. In this embodiment, the external filter 7 comprises a rectangular box without an upper bottom. A basket is placed within the box, and the basket has fine pores on its surface. The oil and water mixture flowing out of the elbow 6 is filtered through the pores on the basket before flowing out through the holes at the bottom of the box. After filtering for a period of time, the basket can be removed from the box and cleaned, and then returned to the box.
[0033] Specifically, due to the dead weight of the oil and water mixture, the oil and water mixture collected at the left end of the sump box 5 enters the external filter 7 from the elbow 6. The external filter 7 performs a secondary filtration on the oil and water mixture, and uses a basket to further filter out the fine food debris that has not been filtered out of the oil drain hole, so that there is as little food residue as possible in the oil and water mixture.
[0034] The processing tank 1 also includes an oil-water separator assembly, which is connected to the bottom hole of the external filter 7 via a hose. After the food residue is further filtered by the external filter 7, the oil-water mixture flows through the hose due to its own weight into the oil-water separator assembly. The oil-water separator assembly is conventional.
[0035] The oil-water separation components include:
[0036] The oil-water separation tank 8 is a rectangular tank in this embodiment. The aforementioned hose connects the external filter 7 with the oil-water separation tank 8.
[0037] The heater 9 is fixedly mounted on the outer wall of the oil-water separation tank 8 and can heat the oil and water mixture in the oil-water separation tank 8 to prevent the grease from condensing.
[0038] A liquid level sensor and an oil level sensor (not shown) are fixedly mounted on the inner wall of oil-water separation tank 8 to detect the water and oil levels, respectively. Because oil-water separation tank 8 separates oil and water based on their different densities, the oil level sensor should be mounted above the liquid level sensor.
[0039] The oil drain pump (not shown) has its inlet at the same height as the oil level sensor and is activated by a controller electrically connected to the oil level sensor. When the oil in the oil-water separation tank 8 reaches the oil level sensor, the oil level sensor triggers. Upon receiving the trigger signal from the oil level sensor, the controller starts the oil drain pump. Once the oil level falls below the oil level sensor, the oil level sensor no longer triggers, and the controller stops the oil drain pump. A drain valve is installed on the oil-water separation tank 8, below the level sensor and electrically connected to the controller. When the liquid level reaches the level sensor, the controller opens the drain valve, allowing wastewater to drain from the device. When the liquid level falls below the level sensor, the controller closes the drain valve.
[0040] An oil collecting barrel 10 is placed inside the processing box 1, and a weighing module 11 is also placed inside the processing box 1. The weighing module 11 belongs to the existing technology. In this embodiment, the weighing module 11 is composed of an electronic scale, a controller and an alarm unit. The oil collecting barrel 10 is placed on the weighing module 11, and the outlet end of the oil drain pump is connected to the oil collecting barrel 10. The drain pump draws the oil into the oil collecting barrel 10. When the weight of the weighing module 11 reaches a predetermined value, the controller sends a signal to control the corresponding alarm unit to alarm, indicating that the oil collecting barrel 10 is full, reminding personnel to replace the full oil collecting barrel 10 with other empty oil collecting barrels 10, and continue to collect oil with other oil collecting barrels 10.
[0041] The use process of this swill grease recovery device:
[0042] The swill delivery pipe of the relevant catering place is connected to the feed inlet 4 of this swill oil and grease recovery device, allowing the swill in the swill delivery pipe to enter the feed inlet 4. The swill then falls from the feed inlet 4 and the leakage holes 3 into the spiral pusher in sequence. At the same time, the flushing joint is opened, and the purified water also enters the spiral pusher from the feed inlet 4 and the leakage holes 3 in sequence to flush the swill.
[0043] Due to the large amount of swill, during the rotation of the spiral blades of the spiral pusher 2, the swill is squeezed against each other, and the oil and water mixture will be squeezed out from the food residues, thus separating from the food residues, achieving the purpose of squeezing out the water and oil in the swill. The food residues with the oil and water squeezed out leave this device from the right end of the spiral pusher 2 and are then collected by other equipment.
[0044] The oil and water mixture squeezed out from the food residues falls from the oil discharge hole to the liquid collection tank box 5. The oil discharge hole serves the purpose of primary filtration of the food residues in the oil and water mixture; then, the oil and water mixture is collected by the liquid collection tank box 5 and concentrated at its left end; and then the oil and water mixture is guided to the external filter 7 through the elbow 6. The external filter 7 conducts secondary filtration on the oil and water mixture to further remove the food residues in the oil and water mixture.
[0045] Finally, under the action of its own weight, the oil and water mixture flows to the oil-water separation component after passing through the external filter 7. The oil-water separation component utilizes the different densities of oil and water to separate the oil and water. After the oil in the oil-water separation component reaches a certain height and triggers the oil level sensor, after the controller receives the signal from the oil level sensor, the controller controls the oil discharge pump to start and pumps the oil alone into the oil collection barrel 10. The weighing module 11 monitors the weight of the oil. When the predetermined value is reached, it reminds the personnel to replace the empty oil collection barrel 10. After the water in the oil-water separation component reaches a certain height and triggers the liquid level sensor, after the controller receives the signal from the liquid level sensor, the controller controls the drain valve to open and then discharges the water in the oil-water separation component alone using the drain valve.
[0046] Inspired by the above ideal embodiments according to the present utility model, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this utility model. The technical scope of this utility model is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
