However, the above technical solution has a complex structure and a high cost. Summary of the Utility Model

[0003] The purpose of the utility model is to provide an oil-water separation device for kitchen waste, which has a simple structure and a low cost.

[0004] The technical solution adopted by the utility model is as follows:

[0005] An oil-water separation device for kitchen waste includes a separation barrel, a drainage barrel, an inverted U-shaped pipe and a sprinkler head. The separation barrel has a first overflow level. An annular barrel is wrapped outside the separation barrel, and the annular barrel is adapted to receive the overflowed material of the separation barrel.

[0028] Embodiment

[0029] Please refer to Figure 1 、 Figure 2 A kitchen waste oil-water separation device, comprising a separation barrel 10, a drainage barrel 20, an inverted U-shaped pipe 30 and a sprinkler head 40. The separation barrel 10 has a first overflow level 11. An annular barrel is covered outside the separation barrel 10, and the annular barrel is adapted to receive the materials overflowed from the separation barrel 10. Here, in the oil-water mixture, the oil floats on the upper layer of the water, and the oil is discharged by the way of overflow, so as to achieve separation. For example, the annular barrel can also be connected to an oil collection barrel 50 to collect the oil, avoiding excessive land occupation by directly using the annular barrel for collection. The lower part of the oil collection barrel 50 and the lower part of the annular barrel can be connected by a pipeline.

[0030] The drainage barrel 20 has a second overflow level 211. The drainage barrel 20 is connected to the separation barrel 10 through the inverted U-shaped pipe 30. The inverted U-shaped pipe 30 includes a first end 31 and a second end 32. The first end 31 is placed inside the lower part of the separation barrel 10 and the second end 32 is placed inside the lower part of the drainage barrel 20. The height difference from the second end 32 to the second overflow level 211 is 0.92 - 0.99 times the height difference from the first end 31 to the first overflow level 11. For example, the inverted U-shaped pipe 30 is connected from the lower parts of the side walls of both the separation barrel 10 and the drainage barrel 20. Here, with this height difference, it can effectively ensure that the first overflow level 11 is above the water level and located in the oil layer, so that the materials flowing out from the first overflow level 11 are all oil. Preferably, the height difference from the second end 32 to the second overflow level 211 is 0.94 - 0.95 times the height difference from the first end 31 to the first overflow level 11.

[0031] The sprinkler head 40 is adapted to be connected to a feeding device. The sprinkler head 40 is erected above the center of the separation barrel 10, and the bottom outlet of the sprinkler head 40 includes a plurality of through holes 41. Each through hole 41 is connected with a flow guiding column 42. For example, the diameter of the through hole 41 can be 5 - 10 mm. For example, the feeding device can be a pipeline connected with a liquid pump. For example, the flow guiding column 42 can be arranged at the edge of the through hole 41 to guide the oil-water mixture, so that the oil-water mixture flows down along the flow guiding column 42. The flow guiding column 42 can extend into the liquid level of the separation barrel 10, so as to reduce the waves and avoid part of the water flowing out from the first overflow level 11 due to the liquid level fluctuation.

[0032] The oil-water separation device of the present utility model includes a separation barrel 10, a drainage barrel 20, an inverted U-shaped pipe 30 and a sprinkler head 40. During operation, the oil-water mixture is introduced into the sprinkler head 40 from a feeding device and is shunted through a number of through holes 41. Each through hole 41 flows downward through a guide post 42 to the center of the separation barrel 10. The existence of shunting and guiding reduces the impact of the feed on the separation barrel 10, and guiding to the center also reduces the waves of the overflow at the edge, avoiding the surface waves from causing water to flow out through the first overflow level 11. Under the action of the inverted U-shaped pipe 30, due to the siphon effect, the liquid level in the separation barrel 10 will always be at the first overflow level 11. The liquid above the first overflow level 11 is oil, which will overflow to the annular barrel, while the liquid below the first overflow level 11 has some oil floating on the surface and most of it is water at the bottom. The water enters the drainage barrel 20 through the inverted U-shaped pipe 30 and flows out through the second overflow level 211, realizing oil-water separation, with a simple structure and low cost.

[0033] In another embodiment, a valve 33 is provided on the inverted U-shaped pipe 30 outside the separation barrel 10 and the drainage barrel 20. With this arrangement, when the water volume in the drainage barrel 20 is low, the valve 33 can be closed to avoid the backflow of oil in the separation barrel 10.

[0034] In another embodiment, a lockable telescopic cylinder 21 is provided at the top of the drainage barrel 20, and the second overflow level 211 is at the top of the telescopic cylinder 21. With this arrangement, the position of the second overflow level 211 can be changed by lifting and lowering the telescopic cylinder 21, thereby changing the position of the first overflow level 11 in the oil layer, and thus adaptively adjusting according to the specific thickness of the oil layer, so that the oil drainage efficiency of the first overflow level 11 is higher.

[0035] The above are only the preferred embodiments of the present utility model and are not intended to limit the protection scope of the present utility model. Any modifications, equivalent replacements, improvements, etc. made by those skilled in the art within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
