TECHNICAL FIELD
[0001] The utility model relates to a kind of processing equipment of leftovers, especially a kind of device for separating oil and water from kitchen leftovers. BACKGROUND
[0002] China is the country with the largest population in the world, according to the 2023 statistical population has reached 1.4 billion people, with the rapid development of industry and population increase, resulting in a large number of leftovers, especially in office buildings, colleges and universities, hospitals, hotels, hotels, health and wellness centers and other centralized dining places such as restaurants, canteens, etc. The problem of leftovers is more prominent in these places. Leftovers usually include meat and vegetables rich in organic matter, animal and vegetable oil, and water, which are very easy to rot and cause serious environmental pollution.
[0003] The above-mentioned leftovers are often collected in sour water barrels and directly supplied to pig farms as pig feed. Due to long storage and transportation time, especially in summer, the outdoor temperature is relatively high, and the leftovers in the restaurant are easy to breed a large number of microorganisms and bacteria, and to rot and deteriorate, and even to produce and emit odor, which not only pollutes the environment, but also causes pigs to be infected with certain diseases, and if humans eat diseased pork, it will harm humans. In addition, the leftovers collected in the sour water barrel will emit a very unpleasant odor, polluting the environment.
[0004] In particular, a large amount of animal and vegetable oil is left in leftovers, which is harmful to humans and pollutes the environment, and illegal activities to obtain "gutter oil" from leftovers are becoming more and more serious, which is seriously affecting human health. On the other hand, the world is facing an increasing shortage of energy. Therefore, removing high-concentration animal and vegetable oil from leftovers and recycling it not only effectively avoids the pollution of leftover waste animal and vegetable oil to the environment, but also recycles the recycled waste animal and vegetable oil as a raw material for biodiesel, and also recycles the leftovers after removing the oil, to make fertilizer or pet food.
[0005] There are some devices in the prior art that can separate oil and water, such as the kitchen waste sewage oil separation device of Chinese patent No. CN101670193B developed by the inventor, which comprises: a tank body, a sewage inlet at the bottom, an oil outlet and a clean water outlet on the side; an oil-water separation element installed in the tank body, in a cylindrical structure with a closed top and an open bottom, the cylindrical structure forms a first chamber for containing the sewage to be separated inside, and a second chamber for containing the separated oil and water between the outer part of the cylindrical structure and the inner wall of the tank body; a heating device for heating the inside of the tank; a cleaning device for periodically cleaning the oil-water separation element in the tank; a sewage water supply device for supplying sewage to be separated to the first chamber.

[0040] Specifically, as shown in the drawings, Figures 1-5 The box is cuboid, one side upper part is separately separated as oil-water separating chamber 2 for separating oil-water containing in the food remaining of collection in the dining table, the oil-water separating chamber is as the first separation structure, has the oil-water permeable plate 3 with oil-water hole for making oil-water containing in the dining table remaining food flow fast, the oil-water permeable plate is rectangular, three edges are fixedly connected with three inner walls of the box, one edge is fixedly supported by the support frame fixedly connected with the inner wall of the box.The side of the oil-water separating chamber is provided with a baffle 2 to prevent the dining table remaining food from spilling to the outside of the oil-water separating chamber on the side of the baffle when the dining table remaining food is put into the oil-water separating chamber from the side opposite to the baffle, pollute the environment and increase the cleaning difficulty.The part of the box below and beside the oil-water separating chamber is the water storage chamber, and a box cover 4 detachably connected with the upper surface of the box is arranged at the opening of the water storage chamber beside the oil-water separating chamber (the connection mode can adopt the prior art mode, which will not be described in detail here).The sewage discharge pipe 5 for discharging the sewage separated out by the second separation structure is arranged at the bottom of the box, and a manual valve or an automatic valve can be arranged on the sewage discharge pipe, and the sewage separated out by the second separation structure can flow out automatically by opening the valve, and the sewage discharge pipe can be directly or indirectly connected with the kitchen sewage pipe.
[0041] Among them, as shown in the drawings, Figure 1 、 Figure 6 、 Figures 8-11 The bottom plate of the oil-water separating chamber is the oil-water permeable plate with oil-water hole, the dining table remaining food can be poured into the oil-water separating chamber during use, and the oil-water containing in the dining table remaining food can pass through the oil-water hole 32 of the oil-water permeable plate and fall into the water storage chamber below the oil-water separating chamber in the box.
[0042] In order to make the oil-containing water in the remaining food on the dining table not to be affected by the surface tension when passing through the oil-water passing hole of the oil-water passing plate, the oil-water passing plate can adopt the first structure as shown in Figure 8 、 Figure 9 , that is, the oil-water passing plate is a flat plate 31, and a plurality of long-strip-shaped oil-water passing holes 32 are arranged on the flat plate, each row of the oil-water passing holes includes a plurality of oil-water passing holes, and the oil-water passing holes in the adjacent two rows are arranged in a staggered manner (see Figure 8 ) or in a corresponding manner (not shown in the figure). Further, in order to accelerate the speed of the oil-containing water in the remaining food on the dining table when passing through the oil-water passing hole of the oil-water passing plate, the cross section of the long-strip-shaped oil-water passing hole is in a frustum shape, and the upper part of the frustum-shaped oil-water passing hole is narrow and the lower part is wide (as shown in Figure 9 ).
[0043] Alternatively, the oil-water passing plate can also adopt the second structure as shown in Figure 10 、 Figure 11 , that is, the oil-water passing plate includes a plurality of long-strip-shaped screen pieces 33 arranged in parallel, and the oil-water passing holes 32 for the oil-containing water to flow down are formed between the adjacent screen pieces. Further, the cross section of the screen piece is in a frustum shape, and the upper part of the frustum-shaped screen piece is wide and the lower part is narrow, so that the oil-water passing hole formed between the adjacent screen pieces is in a frustum-shaped hole with a narrow upper part and a wide lower part. When manufacturing, the plurality of screen pieces are arranged in parallel and the end parts are welded on the frame, the bottom is supported by one or more rib plates, and the frame is integrally welded on the inner wall of the box. The screen piece is made of non-magnetic wear-resistant high-quality stainless steel, the surface is scratch-free, and the surface is flat and free of distortion after welding. The rib plate supporting the bottom of the screen piece cannot exceed the lower edge of the oil-water passing plate.
[0044] No matter which structure the oil-water passing plate adopts, the upper part of the frustum-shaped oil-water passing hole on the oil-water passing plate is 0.8-1.2mm, preferably 1mm, the taper angle is 11-15 degrees, preferably 13 degrees, and the distance between the adjacent oil-water passing holes is 1.5-2.5mm, preferably 2mm.
[0045] When the oil-water passing plate adopts the frustum-shaped hole with a narrow upper part and a wide lower part, the oil-containing water in the remaining food on the dining table is obviously accelerated when passing through the oil-water passing hole of the oil-water passing plate, and the efficiency of separating the oil-containing water from the food is greatly improved, that is, the processing efficiency of the remaining food on the dining table is improved. The oil-containing water in the remaining food on the dining table is naturally separated from the remaining food by gravity, which is energy-saving, emission-reducing and environmentally friendly.
[0046] When the remaining food on the dining table is poured into the oil-water separating chamber, the remaining food on the dining table is spread on the oil-water passing plate, and the oil-containing water in the remaining food on the dining table flows through the oil-water passing hole of the oil-water passing plate and flows downward to the water storage chamber under the action of gravity.
[0047] As shown in Figure 7 , Figure 13 , the water storage chamber in the box can be divided into two areas, one is the first area below the oil-containing water separation chamber, and the other is the second area beside the oil-containing water separation chamber. Among them, the first area is the area for storing oil-containing water, and the second area is the area for removing oil and sewage from the oil-containing water. A second separation structure is provided in the second area for removing oil and sewage from the oil-containing water.
[0048] Among them, the second separation structure of the utility model comprises: a first baffle 7 vertically arranged below one side of the oil-containing water separation chamber (such as Figure 6 , Figure 7 , Figure 13 right side); a second baffle 9 parallel to the first baffle and located on the side away from the oil-containing water separation chamber; and a third baffle 10 parallel to the second baffle and located on the side away from the first baffle. Further, a pair of groove plates 8 extending oppositely are respectively arranged on the opposite side walls of the first baffle and the second baffle.
[0049] When assembled, the bottom of the first baffle is fixed to the bottom plate of the box, and the two ends are fixed to the pair of opposite side walls of the box; the two ends of the second baffle are fixed to the opposite side walls of the box, and the bottom is a certain distance away from the bottom plate of the box; the bottom of the third baffle is fixed to the bottom plate of the box, and the two ends are fixed to the pair of opposite side walls of the box, and the third baffle can have a certain distance from the right side wall of the box.
[0050] After assembly, the top end of the first baffle is lower than the bottom of the oil-permeable water plate, the top end of the second baffle is higher than the top end of the first baffle and lower than the bottom of the oil-permeable water plate, and the top end of the third baffle is lower than the top end of the first baffle. A pair of groove plates are respectively located near the upper end of the first baffle and the second baffle, and the height of the pair of groove plates relative to the bottom plate of the box is equal, forming a slide.
[0051] Among them, the first baffle and the second baffle form an oil-containing water flow space, the second baffle and the third baffle form a remaining sewage flow space after removing grease from the oil-containing water, and the gap between the bottom of the second baffle and the bottom plate of the box can make the remaining sewage flow between the first baffle and the third baffle after removing grease from the oil-containing water. The third baffle and the right side wall of the box form a sewage storage space for storing sewage that has passed through the third baffle, and the third baffle can limit the liquid level height in the oil-containing water flow space and the remaining sewage flow space.
[0052] When the oil-containing water of the remaining food on the dining table flows through the oil-permeable hole of the oil-permeable water plate and flows downward, it first flows into the corresponding area blocked by the first baffle (such as Figure 7The area to the left of the first baffle plate; when the oily water level reaches the height of the first baffle plate, the oily water will flow over the first baffle plate into the oily water flow space between the first and second baffle plates. Due to the difference in specific gravity between the grease and the wastewater in the oily water, the grease will float on top for a certain period of time, while the wastewater will be below the grease. Due to the gap below the second baffle plate, the wastewater below the grease in the oily water flow space flows towards the third baffle plate, that is, into the remaining wastewater flow space, while the grease will be blocked by the second baffle plate and remain in the upper part of the oily water flow space. When the grease in the oily water flow space reaches a certain thickness, the grease floating on the surface can be removed, achieving the separation of grease from wastewater in the oily water. When the wastewater level in the remaining wastewater flow space is higher than the third baffle plate, it will flow over the third baffle plate into the storage space formed by the third baffle plate and the corresponding side wall of the tank. When the water level in the storage space reaches the preset height, the valve on the drain pipe can be opened, and the wastewater will automatically flow out from the drain pipe. Among them, such as Figure 7 As shown, the sewage pipe 6 is located at the bottom of the tank, with one end extending out of the tank body and the other end connecting to the remaining sewage flow space through a through hole opened on the bottom plate of the tank body between the second baffle and the third baffle. Alternatively, it can connect to the storage space through a through hole opened on the bottom plate of the tank body between the third baffle and the right side wall of the tank body. It can also connect to the two spaces respectively using the above two combined methods.
[0053] To remove grease from the surface of the oil-water flow space, the grease-draining structure of this invention can employ the following method: Figure 6 , Figure 7 The first structure shown includes: an oil collection tank 10 for collecting grease from oily water; and a discharge assembly for discharging the grease from the oil collection tank.
[0054] The oil collection tank 10 is a rectangular trough with one side opening, enclosed by a steel plate. This rectangular trough is positioned between the second and third baffles, and its opening communicates with the oil-water flow space, allowing grease floating on the surface of the oil-water flow space to enter the oil collection tank. The discharge assembly includes a component mounted on the housing with one end extending outside the housing (e.g.,...). Figure 1 The left side has an oil drain pipe 5 connected to the oil collection tank at the other end, and a valve is installed on the oil drain pipe. When grease floating on the surface of the oily water flow space enters the oil collection tank, the valve on the oil drain pipe is opened to discharge the grease through the oil drain pipe. The oil drain pipe can be directly connected to the subsequent grease treatment device, or an oil container can be installed below the outlet of the oil drain pipe to receive the flowing grease.
[0055] In order to make the oil floating on the surface of the oil-containing water flow space into the oil collecting groove, the oil collecting structure further comprises an oil transferring assembly, wherein the oil transferring assembly can be a scoop or a scraper for manually collecting and pushing the oil, and the width of the scoop or the scraper is equivalent to the distance between the first baffle and the second baffle. The scoop can adopt the structure of the prior art, and the scraper can be a flat plate.
[0056] In order to improve the efficiency of collecting and pushing the oil, the oil transferring assembly of the utility model can further adopt the structure for automatically collecting and transferring the oil as shown in Figure 14 , which comprises a reversible motor 123, a lead screw 125 connected with the output shaft of the motor, the two ends of the lead screw being rotatably connected with the corresponding parts of the front side wall and the rear side wall of the box body between the first baffle and the second baffle through bearings 124, a nut 126 matched with the lead screw, and a connecting rod 122 installed below the nut, the end of the connecting rod being provided with a sheet-shaped scraper. When the motor works, the lead screw is driven to rotate, the nut moves along the lead screw, and the scraper moves in the oil-containing water flow space. For example, when the motor rotates forward (or reversely), the scraper moves forward (i.e. towards the direction close to the oil collecting groove), the oil floating on the surface of the oil-containing water flow space is scraped into the oil collecting groove by the scraper, and when the motor reversely rotates (or rotates forward), the scraper moves backward (i.e. towards the direction away from the oil collecting groove) to return to the original position. In the design, the total height of the connecting rod and the scraper is reasonably determined according to the height of the baffle and the pair of groove plates. The control circuit for controlling the forward rotation and the reverse rotation of the motor adopts the prior art circuit, and the structure thereof will not be described herein.
[0057] Further, the oil transferring assembly of the utility model can further adopt another structure as shown in Figure 15 , which is based on the first structure, and the top end of the connecting rod is connected with a telescopic member 127 which can move in the vertical direction. The telescopic member can be an electric push rod, a piston rod of a hydraulic cylinder or a pneumatic cylinder. Of course, the scraper can be directly connected with the telescopic member. When the motor rotates, the lead screw is driven to rotate, the nut moves along the lead screw, the scraper moves above the oil-containing water flow space, and according to the actual situation, the height of the scraper extending into the oil on the surface of the oil-containing water flow space is adjusted through the telescopic member, so that the oil floating on the surface of the oil-containing water flow space is scraped into the oil collecting groove by the scraper.
[0058] Since the collected table remaining food is placed for a long time and / or at a low temperature, the oil-containing water can solidify or be adhered to the table remaining food in a large amount and not easily flow down from the oil hole. In order to solve the above problems, the device for separating the table remaining food and the oil water of the utility model further comprises a water spraying device 200 which can provide hot water and is arranged beside the box body on the basis of the above structure, and the pipeline of the water spraying device can extend above the oil-containing water separation chamber (as shown in Figure 16The pipe end is provided with a water injection head capable of adjusting the injection direction by manpower, hot water with a certain temperature (for example, 20-50 DEG C) is supplied into the oil-water separation chamber through the water injection device, the speed of separating the oil-containing water from the table remaining food can be accelerated, and the oil-containing water can be fully separated from the table remaining food.
[0059] When the device for separating the oil-water from the table remaining food is provided with the water injection device, the collected table remaining food is first poured into the separation chamber, and then is spread on the oil-water permeable plate, hot water is injected on the table remaining food through the water injection device to melt the oil on the table remaining food, and the oil-containing water of the table remaining food flows through the oil passing hole of the oil-water separation plate under the action of gravity and flows downward into the water storage chamber.
[0060] When the oil-containing water of the table remaining food flows through the oil passing hole of the oil-water permeable plate and flows downward, it first flows into the left area of the water storage chamber blocked by the first baffle, that is, the first area; when the water surface height of the oil-containing water reaches the height of the first baffle, the oil-containing water flows over the first baffle into the oil-containing water flowing space, and the oil in the oil-containing water floats on the surface, the sewage under the oil flows toward the remaining sewage flowing space, and the oil is blocked by the second baffle and remains in the upper part of the oil-containing water flowing space. When the oil in the oil-containing water flowing space reaches a certain thickness, the oil floating on the surface is pushed into the oil collecting groove by manual or automatic pushing, and the oil is discharged through the oil discharge pipe, so that the oil in the oil-containing water is separated from the sewage. When the height of the sewage in the remaining sewage flowing space is higher than that of the third baffle, the sewage flows over the third baffle into the storage space, and when the sewage in the storage space reaches a predetermined height, the valve on the sewage discharge pipe is opened, and the sewage flows out of the sewage discharge pipe automatically.
[0061] In summary, the device for separating the oil-water from the table remaining food can quickly separate the oil-containing water from the table remaining food, and the oil in the oil-containing water is naturally separated from the sewage, the overall structure is simple, energy-saving, emission-reducing and environment-friendly, the discharged sewage does not contain a large amount of animal and vegetable oil, can be directly discharged into the urban pipe network and is not easy to block the urban pipe network, reduces the sewage treatment cost and reduces secondary pollution.
[0062] Although the above has made a detailed description of the present application, the present application is not limited thereto, and those skilled in the art can modify it according to the principle of the present application, therefore, all kinds of modifications made according to the principle of the present application should be understood as falling within the protection scope of the present application.
