DETAILED DESCRIPTION

[0024] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0025] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0026] like Figure 1 As shown in Figure 4, an embodiment of the utility model provides a garbage leachate treatment device, comprising: a shell 1, on which a filter box 6 and two electric push rods 2 are fixedly mounted, an extrusion plate 3 and a filter plate 5 are slidably arranged in the filter box 6, the electric push rod 2 is fixedly connected to the extrusion plate 3, a connecting rod 4 is fixedly mounted on the lower surface of the extrusion plate 3, a first spring 7 is fixedly mounted between the connecting rod 4 and the filter plate 5, a gear 8 is rotatably arranged on one side of the shell 1, a sliding frame 9 meshing with the gear 8 is fixedly mounted on the output end of one of the electric push rods 2, two racks 10 meshing with the gear 8 are slidably mounted on the upper side of the filter box 6, a sliding plate 11 is fixedly mounted on one side of the two racks 10, two limit bars 12 are slidably arranged in the filter box 6, and a second spring 13 is fixedly mounted between the filter box 6 and the two limit bars 12.

[0027] In this embodiment, specifically: the two electric push rods 2 are fixedly mounted on the inner top wall of the outer shell 1, the circumferential sides of the extrusion plate 3 and the filter plate 5 are in contact with the inner wall of the filter box 6, and the inner wall of the filter box 6 is provided with a limiting protrusion corresponding to the filter plate 5. The setting of the limiting protrusion can limit the sliding of the filter plate 5 during the extrusion process of the extrusion plate 3, so that after the filter plate 5 stops sliding, it is convenient for the filter plate 5 to form pressure with the extrusion plate 3, so that the extrusion plate 3 can pressurize the leachate.

[0028] In the present embodiment, specifically: four chamfers corresponding to the two limit strips 12 are symmetrically provided on the upper and lower sides of the extrusion plate 3, and four inclinations corresponding to the four chamfers are symmetrically provided at one end of the two limit strips 12 close to each other, and grooves corresponding to the two limit strips 12 are provided on the upper surface of the filter plate 5, and the chamfers are provided to facilitate the sliding of the extrusion plate 3.

[0029] In this embodiment, specifically: a plurality of circular holes are opened on the filter plate 5, one end of the connecting rod 4 passes through the filter plate 5, the first spring 7 is sleeved on the bottom of the connecting rod 4, and the bottom of the connecting rod 4 is fixedly connected to the bottom of the first spring 7. The installation of the first spring 7 can support the filter plate 5, so that after the filter plate 5 is restricted by the limit bar 12, the electric push rod 2 can continue to contract, so that the contraction of the electric push rod 2 drives the sliding plate 11 to slide, so that the sliding plate 11 can clean the filter plate 5.

[0030] In the present embodiment, specifically: a plurality of tooth grooves meshing with the gear 8 are provided on the sliding frame 9, a first protrusion 14 is provided on one side of the filter box 6, two sliding plates 11 are both slidingly arranged on the upper surface of the first protrusion 14, two second protrusions 15 are symmetrically arranged on one side of the first protrusion 14, and third protrusions 16 penetrating the two second protrusions 15 are symmetrically arranged at both ends of the gear 8. The arrangement of the two second protrusions 15 and the two third protrusions 16 facilitates the installation of the gear 8.

[0031] In this embodiment, specifically: two guide bars 101 are arranged inside the shell 1, the upper surfaces of the two sliding plates 11 are in contact with the lower surfaces of the two guide bars 101, and the two sliding plates 11 are slidingly arranged between the two guide bars 101. The arrangement of the two guide bars 101 can guide the sliding plates 11, thereby making the sliding of the sliding plates 11 more stable.

[0032] In this embodiment, specifically: a feed pipe 17 is fixedly installed on one side of the filter box 6, a disc 18 is rotatably provided in the feed pipe 17, and a fifth protrusion 19 is provided on the disc 18. The installation of the disc 18 can seal the filter box 6 after the leachate enters the filter box 6, so that the leachate is not easy to flow out of the feed pipe 17 during the process of the extrusion plate 3 squeezing the leachate.

[0033] In this embodiment, specifically: four universal wheels 20 are installed on the lower surface of the filter box 6, and the four universal wheels 20 are respectively located at a corner of the filter box 6. A fourth protrusion 21 is provided inside the filter box 6. The fourth protrusion 21 is a trumpet-shaped structure, and a discharge hole interconnected with the filter box 6 is opened on the fourth protrusion 21. The installation of the four universal wheels 20 facilitates the movement of the device, and the setting of the fourth protrusion 21 facilitates the filtered leachate to flow out of the device.

[0034] During operation of the utility model, when the filter plate 5 needs to be cleaned, the electric push rod 2 is turned on, the extension and retraction of the electric push rod 2 drives the filter plate 5 and the sliding frame 9 to slide, the sliding of the sliding frame 9 drives the gear 8 to rotate, the rotation of the gear 8 drives the two racks 10 and the two sliding plates 11 to slide, the sliding of the electric push rod 2 drives the extrusion plate 3, the connecting rod 4, the filter plate 5, and the first spring 7 to slide, and after the extrusion plate 3 slides, the two limit bars 12 are pushed to slide away from each other, and the extrusion plate 3 is located at the two limit bars 12 at this time, and the two limit bars 12 are located at the two second springs. The filter plates 5 are pushed by the springs 13 to slide close to each other, and the filter plates 5 are located on the lower surfaces of the two limit bars 12. The electric push rod 2 continues to drive the two sliding plates 11 to slide. During the sliding process of the two sliding plates 11, the residue on the upper side of the filter plates 5 is pushed. After being pushed, the residue is separated from the device, and the filter plates 5 are cleaned by the sliding plates 11. When the two sliding plates 11 clean the filter plates 5, the first spring 7 is squeezed by the sliding connecting rod 4. Because the sliding plates 11 can automatically clean the filter plates 5, the device is more convenient to use.

[0035] When it is necessary to squeeze the leachate entering the device, the leachate is poured into the upper surface of the filter plate 5. At this time, the leachate is located in the filter box 6. The electric push rod 2 is turned on. The extension and retraction of the electric push rod 2 drives the squeezing plate 3 to slide up and down. During the sliding process of the squeezing plate 3, the leachate on the upper side of the filter plate 5 is squeezed. After the leachate is squeezed, the leachate passes through the filter plate 5 faster. Because the leachate passes through the filter plate 5 faster, the efficiency of filtering the leachate by the device is higher.

[0036] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
