DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-5 The present invention provides a technical solution: a drainage device for leachate from a domestic waste landfill, comprising: a garbage bin 1, a liquid guide trough 2 3, a filter 1 6, and a filter 2 7. The bottom of one side of the garbage bin 1 is convex; the liquid guide trough 2 3 is fixed to one end of the garbage bin 1, and a liquid guide trough 1 2 is fixed to one side between the liquid guide trough 2 3 and the garbage bin 1; the filter 1 6 is disposed in the garbage bin 1 and near the liquid guide trough 2 3; the filter 2 7 is disposed in the garbage bin 1 and at a position where the filter 1 6 is near the liquid guide trough 2 3. Domestic waste is landfilled in the garbage bin 1, and then the liquid flows through the liquid guide trough 2 3 into the liquid guide trough 1 2, and then flows through the liquid guide trough 2 to a sewage treatment pool or directly discharged into a ditch; the diameter of the through-holes on the surface of the filter 2 7 is smaller than the diameter of the through-holes on the surface of the filter 1 6, and the solid and liquid in the garbage are separated by the filter 1 6, and the solid and liquid are separated again by the filter 2 7.

[0024] See also Figure 1-4A drainage device for leachate from a domestic waste landfill also includes a cleaning assembly 4, which is arranged between filter screen 1 6 and filter screen 2 7. The cleaning assembly 4 includes a guide rod 41 fixed between the garbage bins 1, a screw rod 44 rotating between the garbage bins 1 and located below the guide rod 41, a movable plate 45 threadedly and slidably connected to the guide rod 41 and the outside of the screw rod 44, a cleaning brush 46 fixed to both ends of the movable plate 45, and a servo motor 43 installed on one side of the garbage bin 1 to drive the screw rod 44 to rotate. The guide rod 41 guides the movable plate 45, thereby ensuring that the movable plate 45 can move smoothly; the cleaning assembly 4 also includes a protective shell 42 fixed to the outer wall of the garbage bin 1 and located above the servo motor 43, and the protective shell 42 is an inverted U-shaped arrangement. The protective shell 42 protects the servo motor 43 and prevents liquid from dripping onto the surface of the servo motor 43 from above; the servo motor 43 is started, and the screw 44 is driven to rotate by the forward and reverse rotation of the output shaft of the servo motor 43. However, during the rotation of the screw 44, the guide rod 41 cooperates to drive the movable plate 45 to move smoothly. Since the cleaning brush 46 and the filter screen 1 6 and the filter screen 2 7 fit tightly together, and the cleaning brush 46 is made of plastic material, when the movable plate 45 moves, the cleaning brush 46 can clean the surface of the filter screen 1 6 and the filter screen 2 7, and at the same time, it can also dredge the through holes on the surface of the filter screen 1 6 and the filter screen 2 7, thereby avoiding the blockage of the filter screen 1 6 and the filter screen 2 7, which affects the subsequent liquid flow; if the device is buried in the soil, the cleaning component 4 can be removed, and the cover plate (not shown in the figure) can be assembled on the liquid guide groove 1 2 and the liquid guide groove 3.

[0025] See also Figure 2-5A leachate drainage device for a domestic waste landfill also includes a solids collection assembly 5 disposed within a waste bin 1 at the bottom between filter screen 1 6 and filter screen 2 7. The solids collection assembly 5 includes a notch 53 formed on one side of the waste bin 1, a collection box 51 slidably mounted within the waste bin 1 through the notch 53, and a baffle 52 fixed to one side of the collection box 51. The baffle 52 has a larger cross-sectional dimension than the notch 53 on the surface of the waste bin 1. After the baffle 52 and the garbage bin 1 are tightly fitted, a small amount of liquid can flow out from the gap 53, or a rubber sealing gasket can be glued to the side of the baffle 52 close to the garbage bin 1, so that the phenomenon of liquid outflow can be completely avoided; after the collection box 51 is slid and assembled inside the garbage bin 1, the outer wall of the collection box 51 and the inner wall of the garbage bin 1 are tightly fitted, so that the solids can fall into the collection box 51 as much as possible and avoid falling into the gap between the collection box 51 and the garbage bin 1; the solid collection assembly 5 also includes a telescopic rod 55 rotating on the outer wall of the garbage bin 1, a back plate 54 fixed to one side of the telescopic rod 55, and a spring 56 fixed to the outer wall of the garbage bin 1 and outside the telescopic rod 55, and the other end of the spring 56 is fixedly connected to the back plate 54, and the back plate 54 and the baffle 52 are inserted. Connection. The telescopic rod 55 forms a reset structure through the spring 56, and a groove for inserting the support plate 54 is opened on the outer wall of the baffle 52. After the support plate 54 rotates, one side of the support plate 54 corresponds to the groove on the outer wall of the baffle 52. At this time, the support plate 54 is inserted into the groove on the outer wall of the baffle 52 under the action of the spring 56, so that the collection box 51 can be firmly assembled on the inner wall of the garbage bin 1.

[0026] Working principle: First, domestic garbage is poured into the garbage bin 1, and the solids and liquids in the garbage are filtered through the filter screen 1 6 and the filter screen 2 7. At this time, the liquid flows into the liquid guide groove 2 3, flows along the liquid guide groove 2 3 to the liquid guide groove 1 2, and can be discharged into the sewage treatment pool through the liquid guide groove 1 2; however, when the filter screen 1 6 and the filter screen 2 7 separate the solid and liquid of the garbage, the solids blocked by the filter screen 2 7 fall into the collection box 51 under gravity and are collected by the collection box 51. Subsequently, the collection box 51 is pulled out of the garbage bin 1 and cleaned. After completion, the collection box 51 can be assembled back into the garbage bin 1; finally, when it is necessary to clean the surface of the filter screen 1 6 and the filter screen 2 7, the servo motor 43 is started, and the output shaft of the servo motor 43 drives the screw 44 to rotate, and the screw 44 is used to move the cleaning brush 46 in cooperation with the guide rod 41, and the cleaning brush 46 is used to clean and dredge the surface of the filter screen 1 6 and the filter screen 2 7 to avoid clogging of the filter screen 1 6 and the filter screen 2 7.

[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
