Description

Technical Field

[0001] The utility model relates to a kitchen waste treatment system, in particular to an oil-water separation device. Background Art

[0002] At present, a Chinese patent with authorization announcement number CN215360023U discloses a solid-liquid separation system in a garbage disposal equipment, wherein the oil-water separation device includes a separation box, a filter fence, and an oil storage box. The filter fence is fixed inside the separation box and is close to the opening on the upper side of the separation box. Since the specific gravity of oil is smaller than that of water, the oil will float on the end of the water. By setting the filter fence, the oil and water can be effectively separated. When the oil reaches a certain amount, the oil storage box is used to recycle the oil. A filter basket for filtering solid precipitation is also placed inside the separation box, and a number of partitions are arranged at vertical intervals in the separation box.

[0003] This oil-water separation device has a simple structure, but kitchen waste is usually composed of solid waste, water and oil. This oil-water separation device is obviously unable to filter and separate water and solid waste, and is therefore not very practical. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide an oil-water separation device to achieve the purpose of filtering and separating solid waste, water and oil.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: an oil-water separation device, comprising a box body with an opening at the upper end, a feed hole is provided on the side wall of the box body, a support frame close to the feed hole is fixedly connected to the box body, a plurality of filter plates are fixedly connected to the support frame, the plurality of filter plates are arranged along the height direction of the support frame, the filter plates are arranged in an inverted V shape, a first baffle is fixedly connected to one side of the support frame close to the feed hole, a baffle plate is fixedly connected to the other side, a plurality of first filter holes are provided on the baffle plate, a second baffle is provided on the side of the baffle plate facing away from the first baffle, the second baffle is fixed on the support frame, an oil storage tank is provided in the middle of the box body, and the height of the upper edge of the oil storage tank is higher than the height of the lower edge of the second baffle.

[0006] To implement the above technical solution, the garbage is poured onto the filter plate. Since the filter plate is arranged in an inverted V shape, the garbage can move down along the filter plate, so that the solid garbage falls to the bottom of the box after being filtered through multiple filter plates. Water and oil pass through the filter plate. Since the specific gravity of oil is less than that of water, the oil floats on the surface of the water, and the oil falls into the oil storage tank while the water does not fall into the oil storage tank. Water can be obtained at the end of the box away from the feed hole, thereby realizing the filtration and separation of solid garbage, water and oil.

[0007] As a preferred solution of the utility model, a first inclined plate and a second inclined plate located above the first inclined plate are fixedly connected in the box body, the first inclined plate and the second inclined plate are located on the side of the oil storage tank facing away from the second baffle, the height of the lower edge of the second inclined plate is lower than the height of the upper edge of the oil storage tank, and a channel is formed between the lower edge of the first inclined plate and the box body.

[0008] To implement the above technical solution, the oil is located above the water. As the water flows, the water passes through the gap between the first inclined plate and the second inclined plate. The oil moves up along the second inclined plate under the obstruction of the second inclined plate, so that the oil enters the oil tank from the side of the oil tank away from the filter plate.

[0009] As a preferred solution of the utility model, a support plate is fixedly connected in the box body, a sedimentation area is formed between the support plate and the inner wall of the box body, a discharge plate is fixedly connected above the support plate, a plurality of second filter holes are provided on the discharge plate, a height of the lower edge of the discharge plate is lower than a height of the upper edge of the oil storage tank, and the discharge plate is located on the side of the second inclined plate facing away from the oil storage tank.

[0010] To implement the above technical solution, the solid waste mixed in the water is located below the discharge plate due to the obstruction of the support plate, the water passes through the discharge plate to achieve secondary filtration, and small particles of solid waste pass through the discharge plate and fall into the sedimentation area for sedimentation to further achieve filtration and separation.

[0011] As a preferred solution of the utility model, the box body is sequentially covered with a first end cover, a second end cover and a third end cover along its length direction, the first end cover corresponds to the filter plate, the second end cover corresponds to the oil storage tank, and the third end cover corresponds to the side of the discharge plate facing away from the oil storage tank.

[0012] To implement the above technical solution, the first end cover, the second end cover and the third end cover are arranged on the box body to achieve an odor-proof effect. After the first end cover is removed from the box body, garbage can be poured into the box body, after the second end cover is removed from the box body, the oil storage tank can be cleaned, and after the third end cover is removed from the box body, the box body can be cleaned.

[0013] As a preferred solution of the utility model, a water outlet hole is provided on the third end cover, and a first outlet hole and a second outlet hole are respectively provided at both ends of the box body, and the first outlet hole and the second outlet hole are both close to the bottom wall of the box body.

[0014] By implementing the above technical solution, both the first discharge hole and the second discharge hole can discharge solid waste, and the water located above the sedimentation area can be extracted by inserting a water pipe into the water discharge hole.

[0015] As a preferred solution of the utility model, the oil storage tank includes a fixed plate and a box body, the fixed plate is fixed to the inner wall of the box body, the box body is located below the fixed plate, a leak-proof plate is fixedly connected to the inner wall of the box body, the fixed plate and the leak-proof plate are connected by a connecting mechanism, and an inclined extension plate is fixedly connected to the side wall of the box body.

[0016] To implement the above technical solution, the leak-proof plate prevents the oil from fluctuating and leaking out in the box body, and the extension plate reduces the lateral impact of water on the box body, making the box body more stable.

[0017] As a preferred solution of the utility model, the connecting mechanism includes a connecting rod, a connecting sleeve and an elastic component, the upper end of the connecting rod is in contact with the fixed plate, the lower end of the connecting rod passes through the leakage-proof plate, the connecting sleeve is arranged on the connecting rod and is in contact with the lower surface of the leakage-proof plate, and the connecting sleeve is positioned on the connecting rod by the elastic component.

[0018] To implement the above technical solution, the upper end of the connecting rod is in contact with the fixed plate, and the lower end of the connecting rod is connected to the connecting sleeve, so that the connecting sleeve is in contact with the lower surface of the leak-proof plate to achieve a supporting effect on the box body. Through the positioning effect of the elastic component, the connecting sleeve is positioned at different positions of the connecting rod, so that the height position of the box body can be adjusted to adapt to different water flow rates and improve practicality.

[0019] As a preferred solution of the utility model, the elastic component includes a mounting hole, a spring sheet and a positioning recessed hole. A plurality of the mounting recessed holes are opened on the outer wall of the connecting rod and are arranged along the length direction of the connecting rod.
