[0002] With the continuous improvement of people's living standards, the requirements for environmental conditions are also increasing day by day. The traditional garbage stations in urban and rural areas can no longer meet the requirements of new concepts such as high efficiency, environmental protection, energy conservation and low consumption. Therefore, the popularization of compressed garbage stations is imperative. During the garbage treatment process, it is necessary to squeeze out the leachate in the garbage, and then complete the treatment work through the treatment device, so as to better complete the garbage treatment work.

[0003] For example: The Chinese utility model patent with the publication number CN210613101U discloses a leachate treatment device for a garbage transfer station, which includes a truss, a telescopic filter frame, a filter box and a water collecting plate. A telescopic filter frame is horizontally arranged at the center of the top of the truss, and a thrust plate and a compression plate are respectively fixed at the left and right ends of the telescopic filter frame. A hydraulic cylinder is horizontally installed on the outer wall of the truss on the right side of the compression plate. A water collecting plate is arranged directly below the telescopic filter frame, and support plates are welded on the inner walls of the truss on the left and right sides of the water collecting plate. A filter box is arranged on the right side of the truss. A flocculation net, a coarse filter screen and a fine filter screen are sequentially arranged in the filter box from left to right, and slots are equally spaced and fixed on the front and rear inner side walls of the filter box. This leachate treatment device for a garbage transfer station not only efficiently collects sewage and completes filtration, improves the treatment quality of the leachate in the garbage transfer station, but also is convenient for cleaning and replacing each component, ensuring the continuity during the treatment of the leachate in the garbage transfer station.

[0044] Compared with the prior art, at least one of the above one or more technical solutions in the leachate treatment device of the garbage transfer station provided by the embodiment of the present utility model has the following technical effects:

[0045] Referring to Figure 1 and Figure 2 , during use, the inlet and outlet 210 is opened through the cylinder cover 220, and the garbage to be treated is put into the extrusion cylinder 200 from the inlet and outlet 210, and then the cylinder cover 220 is closed to cover the inlet and outlet 210; the electric cylinder 230 is started, and the output end of the electric cylinder 230 drives the push plate 240 to move along the axis of the extrusion cylinder 200 to extrude the garbage in the extrusion cylinder 200. The leachate generated by extruding the garbage flows into the liquid receiving tank 300 from a plurality of liquid outlet holes 201. At the same time, the fan 430 operates, and the odor gas emitted from the leachate in the liquid receiving tank 300 is sucked into the housing 410 through the air suction pipe 420. The odor gas is filtered by the gas filtration structure 440 and then discharged from the air outlet 412, realizing the treatment of the odor gas and avoiding environmental pollution caused by the direct discharge of the odor gas; the leachate in the liquid receiving tank 300 flows into the leachate treatment tank 500 through the connecting pipe 510. After being treated by the leachate treatment tank 500, the leachate is discharged through the drain valve 520 through a pipeline to a standardized treatment mechanism for centralized treatment.

[0046] Further, referring to Figure 2, the housing 410 includes a first cylindrical shell 413 and a second cylindrical shell 414. The first cylindrical shell 413 is fixedly arranged on the liquid receiving tank 300 or the frame 100. The first cylindrical shell 413 has a first barrel opening 413a, and the inner wall of the first barrel opening 413a is provided with internal threads. The second cylindrical shell 414 has a second barrel opening, and a connecting ring 414a extends from the edge of the second barrel opening. The outer wall of the connecting ring 414a is provided with external threads, and the external threads are adapted to be screwed with the internal threads, so that the first cylindrical shell 413 and the second cylindrical shell 414 are detachably connected by screwing, which is convenient for maintaining or replacing the gas filtering structure 440. The air inlet 411 and the air outlet 412 are respectively opened on the first cylindrical shell 413 and the second cylindrical shell 414.

[0047] Further, referring to Figure 2 , the gas filtering structure 440 is detachably installed in the second cylindrical shell 414 from the second barrel opening, and the fan 430 is arranged in the second cylindrical shell 414. When the gas filtering structure 440 is used for a certain period of time, the second cylindrical shell 414 is unscrewed from the first cylindrical shell 413, then the old gas filtering structure 440 is taken out from the second cylindrical shell 414, and the new gas filtering structure 440 is detachably installed in the second cylindrical shell 414 from the second barrel opening, which is convenient for maintaining or replacing the gas filtering structure 440.

[0048] Further, referring to Figure 2 , a plurality of handles (not shown in the figure) are arranged on the outer wall of the second cylindrical shell 414 along its circumferential direction.

[0049] Further, referring to Figure 2 , an odor checker 450 is arranged on the outer wall of the second barrel opening. The detection end 451 of the odor checker 450 extends into the second barrel opening and is located between the fan 430 and the air outlet 412. An exhaust valve 460 is arranged at the air outlet 412. Specifically, the odor checker 450 is used to detect the gas processed by the gas filtering structure 440. When the odor checker 450 detects that the gas meets the emission standards, the exhaust valve 460 opens the air outlet 412 to discharge the gas through the air outlet 412; when the odor checker 450 detects that the gas does not meet the emission standards, the exhaust valve 460 closes the air outlet 412 and the fan 430, prompting the user to replace the new gas filtering structure 440, and the structure is reliable.

[0050] Among them, the odor checker 450 is a mature existing technology, such as SGA-400 / 700 series intelligent odor sensor modules of Shenguoan, XP-329IIIR portable odor detector, Fuzhun GT-1000-ODOR portable odor gas detector, etc.

[0051] Further, referring to Figure 1 , the bottom of the liquid receiving tank 300 is an inclined bottom 320.
