Abstract
Description
Technical Field
[0001] The utility model belongs to the field of catering swill treatment equipment, and particularly relates to a swill solid-liquid separation device. Background Art
[0002] With the increasing number of large catering food plazas such as various complexes, enterprise canteens, school canteens, hotels, and food cities, the problem of treating swill grease in the catering industry has become increasingly prominent. 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 a significant waste of human 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, it will not only bring huge economic benefits but also provide a new direction for environmental governance.
[0003] The existing method for filtering solids and liquids in swill mainly uses a filter basket. The solid food residues in the swill are filtered through the holes on the surface of the filter basket, and the liquid oil-water mixture leaks downward.
[0004] In the use of this existing technology, it is found that since the swill is not extruded, it is easy to cause a high oil content in the food residues, and the solid-liquid separation of the swill is not thorough. Content of the Utility Model
[0005] A swill solid-liquid separation device of the utility model is used to separate solids and liquids in swill as much as possible.
[0006] A swill solid-liquid separation device of the utility model includes a processing tank and a spiral pusher. One end of the spiral pusher is inside the processing tank, and the other end is outside the processing tank. An outlet for residues is provided at the end of the spiral pusher outside the processing tank. Leak holes are provided on the outer shell of the spiral pusher, and the leak holes are inside the processing tank. A feed inlet is provided on the processing tank. The swill can enter the spiral pusher through the feed inlet and the leak holes in sequence. The spiral pusher can push the swill from the leak holes to the outlet for residues.
[0007] A number of oil discharge holes for discharging the oil and water mixture in the spiral pusher are provided at the bottom end of the outer shell of the spiral pusher. A liquid collecting tank box is fixed at the bottom end of the outer shell of the spiral pusher. The liquid collecting tank box is used to collect the oil and water mixture leaking from the oil discharge holes.
[0008] A flushing joint is provided at the feed inlet, and the flushing joint can flow clean water into the leak holes.
[0009] Furthermore, the liquid collecting tank box wraps the oil discharge holes at the bottom end of the outer shell of the spiral pusher. The liquid collecting tank box is inclined. A bent pipe is connected to the lower end with a lower height of the liquid collecting tank box, and the bent pipe is connected to the oil-water separation device.
[0010] It is capable of concentrating the oil-water mixture flowing out of the oil drain hole, preventing the oil and water from flowing into the box body. The elbow can guide the oil and water to the oil-water separation device. By setting the elbow at the lower end of the liquid collection tank box, it can尽可能地 avoid the oil and water remaining in the liquid collection tank box.
[0011] Furthermore, the feed inlet is funnel-shaped.
[0012] It is convenient to concentrate the swill, enabling the swill to accurately enter the leakage holes and then into the spiral pusher.
[0013] Furthermore, the oil drain holes are densely distributed at the bottom end of the outer shell of the spiral pusher.
[0014] When the oil drain holes are densely distributed at the bottom end of the outer shell of the spiral pusher, after the swill is squeezed, the oil-water mixture will fall from various positions at the bottom end of the outer shell of the spiral pusher. If the oil drain holes are only set at the lower end of the spiral pusher, the oil-water mixture squeezed out from the higher end of the spiral pusher will have a longer flow path before it can be discharged from the oil drain holes, resulting in low oil drainage efficiency. The food residues will be re-contaminated with the oil-water mixture due to the low oil drainage efficiency, causing incomplete solid-liquid separation. [[ID=...]]
[0015] Furthermore, the spiral pusher is inclined, and the leakage holes are located at the lower end of the spiral pusher.
[0016] When the swill is conveyed from the lower end to the higher end of the spiral pusher, due to the self-weight of the swill, the swill itself will be squeezed. In this way, when the spiral pusher conveys the swill, the swill will be further squeezed by the spiral blades of the spiral pusher. Under the double squeezing, it is easier to achieve solid-liquid separation. If the spiral pusher is placed horizontally, the squeezing caused by the self-weight of the swill will be lost, resulting in a weakened solid-liquid separation effect. Beneficial effects
[0017] The spiral pusher is used to convey the food residues from one end to the other end. Since the spiral pusher will squeeze the swill during the conveying process, the oil in the swill will be squeezed out, and then the squeezed grease will be discharged from the spiral pusher through the oil drain holes.
[0018] A flushing joint is provided, which can flow out clean water and enter the spiral pusher. The clean water flushes the grease on the swill. When the swill is squeezed, the oil-water mixture is squeezed out from the food residues, achieving the purpose of further separating the grease from the swill. Description of the drawings

[0021] 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. Obviously, 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 fall within the scope of protection of the present utility model.
[0022] See Figure 1 , a garbage solid-liquid separation device, including a treatment tank 1, on which a spiral pusher 2 is fixedly installed. The spiral pusher 2 belongs to the prior art and is composed of spiral blades welded on a shaft and a housing, and the housing is fixedly connected to the inner wall of the treatment tank 1. The spiral blades are driven to rotate by a low-power brushless motor.
[0023] In this embodiment, viewed from Figure 1 a perspective, the spiral pusher 2 is inclined, with the left end of the spiral pusher 2 being low and the right end being high. The left end of the spiral pusher 2 is located inside the treatment tank 1, and the right end of the spiral pusher 2 is outside the treatment tank 1.
[0024] A leakage hole 3 is opened at the top of the left end of the housing of the spiral pusher 2, and a feed inlet 4 is opened at the top of the treatment tank 1, and the feed inlet 4 is above the leakage hole 3. In this embodiment, the shape of the feed inlet 4 is funnel-shaped, and the garbage water is directly poured into the funnel-shaped feed inlet 4. Under the action of the self-weight of the garbage water, it gathers along the inner wall of the funnel shape and falls from the bottom of the feed inlet 4 to the leakage hole 3, and finally enters the spiral pusher 2. The spiral blades of the spiral pusher 2 rotate, and the spiral blades convey the food residues from the left end of the spiral pusher 2 to the right end of the spiral pusher 2. Finally, the food residues脱离 the treatment tank 1 from the right end of the spiral pusher 2. An outlet for residues is opened on the right end of the housing of the spiral pusher 2, and the food residues falling from the outlet for residues are collected by a corresponding residue collection bucket.
[0025] In order to enable the grease on the garbage water to be more smoothly separated from the food residues, a flushing joint (not shown) is provided at the feed inlet 4, and the flushing joint can flow out clean water. In this embodiment, the clean water is tap water. The clean water flows along the inner wall of the funnel-shaped feed inlet 4, and the clean water relies on its own weight to flow to the leakage hole 3 and finally also enters the spiral pusher 2. The clean water contacts the garbage water directly poured into the spiral pusher 2, playing a role in flushing the grease on the garbage water, making it easy for the grease on the garbage water to separate from the food residues under this flushing action.
[0026] A number of oil discharge holes are opened on the housing of the spiral pusher 2. The oil discharge holes are located at the bottom end of the spiral pusher 2 and are densely distributed on the housing of the spiral pusher 2 along the direction of the axis of the spiral pusher 2, ensuring that the oil and water mixture at each position of the spiral pusher 2 can脱离 the spiral pusher 2 from the oil discharge holes.
[0027] As the screw propeller 2 conveys the swill, the grease on the swill is smoothly separated from the food residue by the aforementioned flushing action of the clean water. 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 residue is a solid object, its size is much larger than the oil drain hole, so the food residue will not seep downward from the oil drain hole.
[0028] 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.
[0029] The left end of the liquid collecting tank box 5 is fixedly connected with an elbow 6, one end of the elbow 6 is connected to the liquid collecting tank box 5, and the other end extends out of the processing box 1 and is connected to the oil-water separation device. The oil-water separation device is disclosed in other patents of the company and belongs to the prior art, so it will not be repeated in this solution.
[0030] The use of this device
[0031] The swill enters the device from the feed port 4, and falls into the screw pusher 2 from the feed port 4 and the leakage hole 3 in turn. At the same time, the flushing joint is opened, and clean water also enters the screw pusher 2 from the feed port 4 and the leakage hole 3 in turn to flush the swill.
[0032] Because the amount of food residue is large, the spiral blades of the auger 2 rotate, squeezing the food residue against each other. The oil and water mixture is squeezed out of the food residue, thereby separating the food residue and squeezing out the water and oil from the food residue. The food residue that has been squeezed dry of oil and water is separated from the device from the right end of the auger 2 and then collected by other equipment.
[0033] The oil and water mixture squeezed out from the food residue falls from the oil drain hole to the sump box 5, and is guided to the oil-water separator through the elbow 6, where the oil and water are separated.
[0034] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
