[0032] As Figure 1a , Figure 1b , Figure 12 indicated, the structure schematic view of the remaining food oil removing device of the utility model adopts different structures, and as shown in the drawing, the remaining food oil removing device 100 of the utility model includes a box body 1, in addition, further includes: a first separation structure arranged in the box body and used for separating the oil-containing water in the collected remaining food of the dining table from the food; a second separation structure arranged in the box body and used for separating the oil from the sewage in the oil-containing water separated by the first separation structure; and a sewage discharge pipe arranged at the lower part of the box body and used for discharging the sewage separated by the second separation structure.

[0033] Specifically, as Figures 1a-5 indicated, the box body of the utility model is in the shape of a cuboid, one side upper part thereof is separately separated as an oil-containing water separation chamber 2 for separating the oil-containing water in the collected remaining food of the dining table from the food, the oil-containing water separation chamber serves as the first separation structure, has a water-oil permeable plate 3 with water-oil permeable holes for allowing the oil-containing water in the remaining food of the dining table to flow quickly, the water-oil permeable plate is in the shape of a rectangle, three edges thereof are fixedly connected with three inner walls of the box body, and one edge is fixedly supported by a support frame fixed to the inner wall of the box body. The part of the box body located below and beside the oil-containing water separation chamber is a water storage chamber 8, and a box cover 4 detachably connected with the upper surface of the box body is arranged at the opening of the water storage chamber located beside the oil-containing water separation chamber (the connection mode can adopt the existing technical mode, which will not be described herein again). A sewage discharge pipe 5 (as Figure 1a indicated) can be adopted, or two sewage discharge pipes, i.e., a first sewage discharge pipe 5 and a second sewage discharge pipe 6 (as Figure 1b indicated), can be adopted, and a manual valve is arranged on each sewage discharge pipe, and the sewage separated by the second separation structure can automatically flow out by opening the valve.

[0034] The bottom plate of the oil-containing water separation chamber is the water-oil permeable plate with water-oil permeable holes, and the collected remaining food of the dining table can be poured into the oil-containing water separation chamber during use, and the oil-containing water in the remaining food of the dining table can pass through the water-oil permeable holes 32 of the water-oil permeable plate and fall into the water storage chamber located below the oil-containing water separation chamber of the box body.

[0035] 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 6 、 Figure 7 , 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 6 ) 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 7 ).

[0036] Alternatively, the oil-water passing plate can also adopt the second structure as shown in Figure 8 、 Figure 9 , 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 shape 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.

[0037] 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 wide, 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.

[0038] 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 significantly accelerated when passing through the oil-water passing hole of the oil-water passing plate, greatly improving the efficiency of separating the oil-containing water from the food, that is, improving the processing efficiency of the remaining food on the dining table. 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.

[0039] 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.

[0040] As Figure 4 shown, 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 the oil and sewage in the oil-containing water to leave. A second separation structure is arranged in the second area for the oil and sewage in the oil-containing water to leave.

[0041] Among them, the second separation structure of the utility model comprises: a first baffle 9 vertically arranged below one side (such as Figure 4 the left side) of the oil-containing water separation chamber; a second baffle 11 arranged in parallel with the first baffle and located on the side away from the oil-containing water separation chamber; and a third baffle 12 arranged in parallel with the second baffle and located on the side away from the first baffle. Further, a groove plate 10 extending oppositely is arranged on the opposite side walls of the first baffle and the second baffle.

[0042] 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 in front of and behind the box; the two ends of the second baffle are fixed to the side walls in front of and behind 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 left side wall of the box or the bottom is fixed to the left side wall of the box through a horizontal plate, and the two ends are fixed to the pair of opposite side walls in front of and behind the box. 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, the top end of the third baffle is lower than the top end of the first baffle, and a pair of groove plates are located near the upper ends of the first baffle and the second baffle, and the heights of the pair of groove plates relative to the bottom plate of the box are equal, forming a slide. Among them, the first baffle and the second baffle form an oil-containing water flowing space, the second baffle and the third baffle form a remaining sewage flowing space after the grease in the oil-containing water is removed, and the gap between the bottom of the second baffle and the bottom plate of the box can make the remaining sewage after the grease in the oil-containing water is removed flow between the first baffle and the third baffle, and the liquid level height in the oil-containing water flowing space and the remaining sewage flowing space is limited by the third baffle.

[0043] 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 out downward, it first flows to the right area blocked by the first baffle, i.e. the first area; when the water level of the oil-containing water reaches the height of the first baffle, the oil-containing water will flow over the first baffle into the oil-containing water flowing space between the first baffle and the second baffle. Due to the different specific gravities of the grease and sewage in the oil-containing water, the grease in the oil-containing water will float on top after a certain period of time, and the sewage will be below the grease. Due to the existence of the gap below the second baffle, the sewage will flow towards the third baffle, while the grease will be blocked by the second baffle and remain in the upper part of the oil-containing water flowing space.

[0044] When the oil in the oil-containing water flow space reaches a certain thickness, the operator removes the oil floating on the surface to separate the oil in the oil-containing water from the sewage.

[0045] In order to discharge sewage according to different needs, when a sewage discharge pipe is arranged at the lower part of the box, the sewage discharge pipe can be connected to the bottom of the space surrounded by the first baffle and the second baffle, or to the bottom of the space surrounded by the second baffle and the third baffle. When two sewage discharge pipes are arranged at the bottom of the box, one sewage discharge pipe is connected to the bottom of the space surrounded by the first baffle and the second baffle, and the other sewage discharge pipe is connected to the bottom of the space surrounded by the second baffle and the third baffle, or one sewage discharge pipe can be connected to the bottom of any one of the space surrounded by the first baffle and the second baffle and the space surrounded by the second baffle and the third baffle, and the other sewage discharge pipe can be connected to the part between the third baffle and the side wall of the box (not shown in the figure).

[0046] In addition, in order to remove the oil on the surface of the oil-containing water flow space, the second separation structure of the utility model further comprises an oil collecting sieve 13 for removing the oil floating on the surface. Figure 10 、 Figure 11 The oil collecting sieve can adopt the structure as shown in the figure, comprising a sieve body and a handle 132 arranged at the top of the sieve body for easy holding.

[0047] The utility model sieve body is a structure with an oil collecting port inclined upward and backward at the front end, surrounded by a pair of side plates 131, a bottom plate 133, a top plate 135, a front baffle 132, an upper baffle 134 and a back plate, and the handle is fixed to the top plate and can be welded to the top plate. In order to hold comfortably and avoid slipping, a rubber layer or a plastic layer can be wrapped on the handle, or a corrugated convex point structure can be arranged. The sieve body can be made of stainless steel.

[0048] In order to facilitate the removal of the oil floating on the surface of the oil-containing water flow space, and to prevent the oil from easily sliding off the oil collecting port of the oil collecting sieve when the oil is collected by the oil collecting sieve, the side plate of the utility model sieve body adopts the structure as shown in the figure. Figure 11The pentagonal structure shown has its top edge BC and bottom edge AE parallel, its rear side AB perpendicular to both the bottom and top edges, and its front side DE inclined upwards and forwards relative to the bottom edge, forming an angle greater than 90 degrees with the bottom edge. This results in the upper side CD, which connects the top of the front side and the front end of the top side, being an upward-sloping side. This inclined upper side is used to form the grease collection opening of the grease trap. During manufacturing, the pair of sides of the front baffle are seamlessly connected to the front sides of the pair of side plates, the lower edge of the front baffle is seamlessly connected to the front end of the bottom plate, the pair of sides of the upper baffle are seamlessly connected to the upper side plate, and the rear edge of the upper baffle is seamlessly connected to the front edge of the top plate.

[0049] Because the collected leftover food from the table may solidify or adhere heavily to the food due to prolonged storage and / or low temperature, making it difficult for the oil to flow through the oil drain hole, this utility model's leftover food degreasing device, based on the above structure, also includes a water spray device 200 providing hot water on the side of the housing. The pipe of the water spray device can extend above the oil-water separation chamber (e.g., ...). Figure 12 As shown in the diagram, a water nozzle with an adjustable spray direction is installed at the end of the pipe. Hot water at a certain temperature (e.g., 20 to 50°C) is supplied to the oil-water separation chamber via a spray device, which accelerates the separation of oil and water from leftover food, ensuring thorough separation. The water nozzle can be designed similarly to a showerhead, allowing for adjustment of the spray direction towards the leftover food as needed.

[0050] When the food waste removal device has a water spraying device, the collected food waste is first poured into the separation chamber, then spread evenly on the oil-water separating plate. Hot water is sprayed onto the food waste through the water spraying device to fully melt the grease on the food waste. Through gravity, the oil-containing water from the food waste flows through the oil holes of the oil-water separating plate and flows downward into the water storage chamber.

[0051] When the oily water from leftover food on the table flows down through the oil-permeable plate, it first flows into the right-hand area of ​​the water storage chamber, which is blocked by the first baffle, i.e., the first area. When the water level of the oily water reaches the height of the first baffle, the oily water will flow over the first baffle into the oily water flow space. The grease in the oily water will float on top, while the sewage will be below the grease. The sewage below will flow towards the remaining sewage flow space, while the grease will be blocked by the second baffle and remain in the upper part of the oily water flow space.

[0052] When the oil in the oil-containing water flow space reaches a certain thickness, the operator removes the oil floating on the surface along with the oil collecting sieve, so as to separate the oil in the oil-containing water from the sewage.

[0053] In conclusion, the remaining food oil removal device of the dining table can automatically separate the oil-containing water from the remaining food collected on the dining table without external energy, and the oil in the oil-containing water is naturally separated from the sewage, so that 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 oils, 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.

[0054] Although the utility model has been described in detail above, the utility model is not limited thereto, and those skilled in the art can modify it according to the principle of the utility model, therefore, all kinds of modifications according to the principle of the utility model should be understood as falling within the protection scope of the utility model.
