Technical Field

[0001] The utility model relates to the field of domestic garbage leachate treatment, and more specifically, to a device for treating urban domestic garbage leachate. Background Art

[0002] At present, with the development of the economy, the current management and treatment of domestic waste can no longer meet the needs of social development. Domestic waste is widely distributed and difficult to treat.

[0003] When existing equipment processes domestic waste, the domestic waste usually contains some permeates. These permeates generally do not contain toxic substances and can usually be reused. However, these permeates in the waste are easy to seep out and cause pollution, which is not conducive to subsequent treatment.

[0004] After searching, the Chinese patent application number CN202222814969.5 discloses a device for treating leachate from domestic waste. Two columns are set in the domestic waste bin, and a lifting assembly is set on the columns. A filtering device is also set in the domestic waste bin. The pressing assembly is driven by the lifting assembly. After the lifting movement, the pressing assembly and the filtering device are used to squeeze the solid waste and leachate in the domestic waste.

[0005] However, during the use of the above-mentioned equipment, due to the complex composition of domestic waste, which may contain various fibers, debris, etc., the small holes on the filter plate will retain some garbage under the pressure of the filter plate and the pressing component during extrusion, causing the filter plate to be blocked, affecting the overall use efficiency. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a device for treating leachate from urban domestic waste to solve the problems raised in the above-mentioned background technology.

[0014] Technical effects and advantages of this utility model:

[0015] 1. By setting a drawing ring, a first cylinder, a pressure plate, a filter plate, a through hole, a top plate, a top block, a filter hole, a protrusion, a second groove, and a second cylinder, compared with the existing technology, the second cylinder is used to make the top block at the top of the top plate coincide with the through hole at the top of the filter plate, and the first cylinder is turned on to lower the pressure plate, and the pressure plate and the filter plate fully squeeze the garbage, and the pressure plate is raised by the first cylinder, and the output end of the second cylinder is lowered. Due to gravity, the protrusions on both sides of the top plate are just stuck in the second groove inside the drawing ring. At this time, the top of the top block of the top plate contacts the bottom end of the through hole of the filter plate, and the permeate flows out from the gap between the two, and the garbage falling from the through hole will fall on the top block, preventing the garbage on the top block from falling on the top plate and causing blockage.

[0016] 2. By setting up a domestic garbage bin, a draw plate, a first cylinder, a pressure plate, a filter plate, a screw rod, a vertical block, a draw ring, a ring block, a convex ring, a first groove and a movable wrench, compared with the existing technology, the pressure plate is moved downward by the first cylinder, and the pressure plate and the filter plate squeeze the garbage. During squeezing, since a ring block is provided inside the domestic garbage bin, the draw ring is on the ring block, and the convex ring inside the ring block is stuck in the first groove on the outer wall of the filter plate to prevent the filter plate from being deformed due to squeezing. The draw plate is pulled out to take out the separated solid garbage, and the movable wrench is turned to drive the screw rod to rotate, so that the vertical block is moved up and the movable wrench is removed to take out the filter plate for replacement and cleaning.

A top plate 11 is provided inside the pumping ring 8, and a plurality of top blocks 12 are provided on the top of the top plate 11. A plurality of filter holes 13 are provided on the top plate 11.

[0028] The base 1 is provided with a second cylinder 14, the output end of the second cylinder 14 passes through the inner wall of the domestic waste bin 3 and extends into the interior of the domestic waste bin 3, and the output end of the second cylinder 14 is slidably connected to the top plate 11, and a rubber ring 15 is provided on the outer wall of the output end of the second cylinder 14. A drain pipe 16 is fixedly connected to the bottom of the domestic waste bin 3.

[0029] Furthermore, a ring block 17 is fixedly connected to the interior of the trash can 3, and the ring block 17 is movably engaged with the pull-out ring 8 to fix the pull-out ring 8.

[0030] Furthermore, a convex ring 18 is provided inside the draw ring 8 , and a first groove 19 is provided on the outer wall of the filter plate 9 . The convex ring 18 is slidably connected to the first groove 19 to fix the filter plate 9 .

[0031] Furthermore, a protrusion 20 is provided on the outer wall of the top plate 11, and a second groove 21 is provided on the inner wall of the draw ring 8. The protrusion 20 is slidably connected to the second groove 21 so that the top plate 11 can move up and down.

[0032] Furthermore, two vertical grooves 22 are provided inside the pull-out ring 8, and screw rods 23 are provided inside the two vertical grooves 22. Two vertical blocks 24 are fixedly connected to the outer wall of the filter plate 9. The two vertical blocks 24 are transmission-connected to the screw rod 23. An adjustable wrench 25 is movably connected to the top of the screw rod 23 to facilitate disassembly and cleaning of the filter plate 9.

[0033] Furthermore, the number of the top blocks 12 is the same as the number of the through holes 10 , and the top blocks 12 match the through holes 10 to facilitate the squeezing of garbage and the discharge of the permeate.

[0034] The working principle of the utility model is as follows: first, pull out the extraction plate 7, put the domestic garbage in after pulling it out, put the extraction plate 7 back into the domestic garbage bin 3, and then turn on the second cylinder 14. The second cylinder 14 drives the top plate 11 to fit it with the filter plate 9. At this time, the top block 12 on the top plate 11 completely overlaps with the through hole 10 on the filter plate 9. Then turn on the first cylinder 4 to lower the pressure plate 5. Finally, the pressure plate 5 and the filter plate 9 are pressed against each other to squeeze out the permeate in the garbage. During extrusion, the convex ring 18 on the extraction ring 8 cooperates with the first groove 19 on the filter plate 9, the extraction ring 8 cooperates with the ring block 17 inside the domestic garbage bin 3, and the second cylinder 14 under the top block 12 offsets the force to prevent the filter plate 9 from deformation caused by extrusion. After the extrusion is completed, the first cylinder 4 raises the pressure plate 5, and the output end of the second cylinder 14 The top plate 11 begins to fall due to the influence of gravity. Since the protrusions 20 on both sides of the top plate 11 are provided, the top of the top block 12 on the top plate 11 contacts the bottom of the through hole 10 on the filter plate 9. The fallen garbage will fall between the top block 12 and the through hole 10. The permeate flows out from the gap, flows along the filter holes 13 on the top plate 11 to the bottom of the domestic garbage bin 3 and is finally discharged from the drain pipe 16. By pulling out the extraction plate 7 and rotating the adjustable wrench 25 on the upper end of the extraction ring 8, the adjustable wrench 25 drives the screw rod 23 to rotate so that the vertical plates 24 on both sides of the filter plate 9 move upward. Finally, the filter plate 9 moves to the extraction ring 8 mouth, and the filter plate 9 is disassembled by disassembling the adjustable wrench 25 for cleaning and replacement. The pressed solid garbage is taken out by pulling out the extraction plate 7.
