[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] (1) For this garbage leachate zero-emission treatment device, when treating garbage, the garbage is input into the interior of the box body through the feed hopper, and then the pressing plate is driven to move horizontally by the connecting component. When the pressing plate moves, the garbage on the partition board will be driven to move synchronously.

Detailed Embodiments

[0023] This part will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the drawings. The role of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it cannot be understood as a limitation on the protection scope of the present invention.

[0024] Please refer to Figures 1-5, the present utility model provides a technical solution: a zero-emission treatment device for landfill leachate, including a box body 1. A feed hopper 2 is arranged on the upper surface of the box body 1, and the lower side of the feed hopper 2 penetrates into the interior of the box body 1. A partition plate 3 is fixedly connected to the inner wall of the box body 1. The right side surface of the partition plate 3 is inclined. A cavity 4 is formed inside the partition plate 3. The right side of the cavity 4 extends out of the right side surface of the partition plate 3. There is a gap between the partition plate 3 and the right side surface of the box body 1. A pressing plate 5 is slidably connected to the upper surface of the partition plate 3. Sliding grooves 6 are respectively formed in the front and rear inner walls of the box body 1. The lower sides of the two sliding grooves 6 communicate with the interior of the cavity 4. Connecting plates 7 are respectively fixedly connected to the front and rear side surfaces of the pressing plate 5. The two connecting plates 7 respectively extend into the interior of the cavity 4 through the two sliding grooves 6. A filter plate 8 is slidably connected to the inner wall of the cavity 4. A connecting component is arranged inside the cavity 4. When treating garbage, the garbage is input into the interior of the box body 1 through the feed hopper 2. Subsequently, the connecting component is used to drive the pressing plate 5 to move horizontally. When the pressing plate 5 moves, it will synchronously drive the garbage on the partition plate 3 to move. At the same time, it will also drive the filter plate 8 to move through the connecting plate 7 and in cooperation with the connecting component. After the filter plate 8 moves, it fills the gap between the partition plate 3 and the box body 1. Under the continuous movement of the pressing plate 5, the garbage is squeezed so that the internal leachate is discharged and falls through the filter plate 8. Through the above structure, when treating garbage, the internal leachate can be quickly discharged by squeezing, improving the overall discharge efficiency, and the overall size of the garbage can be reduced by squeezing, thus facilitating the subsequent collection of the garbage.

[0025] Further, the connecting component includes a displacement plate 9 which is slidably connected to the inner wall of the cavity 4. A spring 10 is fixedly connected to the right side surface of the displacement plate 9, and the right end of the spring 10 is fixedly connected to the left side surface of the filter plate 8. A motor 11 is fixedly connected to the left side surface of the box body 1. The output end of the motor 11 rotates through the inside of the cavity 4. A threaded rod 12 is fixedly connected to the output end of the motor 11. The right end of the threaded rod 12 threadedly penetrates through the right side surface of the displacement plate 9. A second partition plate 13 is fixedly connected to the bottom wall of the box body 1. A second filter plate 14 is fixedly connected to the upper surface of the second partition plate 13. The right side surface of the second filter plate 14 is fixedly connected to the right inner wall of the box body 1. The second filter plate 14 is integrally inclined. A telescopic groove 26 is formed in the lower side surface of the pressing plate 5. A second spring 27 is fixedly connected to the top wall of the telescopic groove 26. The lower end of the second spring 27 is fixedly connected to a telescopic plate 28. The left side surface of the telescopic plate 28 is inclined. A rotating shaft 15 is rotatably connected between the front and rear inner walls of the box body 1. A baffle 16 is sleeved on the outer surface of the rotating shaft 15. A gear 17 is fixedly connected to the front end of the rotating shaft 15. A second sliding groove 18 is formed in the bottom wall of the cavity 4. The outer surface of the gear 17 extends into the inside of the second sliding groove 18. An L-shaped connecting plate 19 is fixedly connected to the front side surface of the filter plate 8. A toothed plate 20 is fixedly connected to the lower side surface of the L-shaped connecting plate 19. The lower surface of the toothed plate 20 is meshed with the outer surface of the gear 17. A treatment box 21 is fixedly connected to the right side surface of the box body 1. A pump body 22 is fixedly connected to the bottom wall of the treatment box 21. The input end and the output end of the pump body 22 are respectively fixedly connected with a transmission pipe 23. An activated carbon filter screen 24 is fixedly connected to the inner wall of the treatment box 21. A discharge pipe 25 is arranged on the right side surface of the treatment box 21. By synchronously driving the threaded rod 12 to rotate through the motor 11, since the displacement plate 9 is slidably connected inside the cavity 4 to limit its own movement track, when the threaded rod 12 rotates, it will synchronously drive the displacement plate 9 to move. When the displacement plate 9 moves, it will synchronously drive the filter plate 8 to move by using the spring 10. After the filter plate 8 moves and contacts the right inner wall of the box body 1, at this time, when the displacement plate 9 continues to move, it will compress the spring 10 and continue to drive the pressing plate 5 to move. When the pressing plate 5 moves to the inclined surface of the partition plate 3, it will use the second spring 27 to push out the telescopic plate 28 and make the second telescopic plate 28 closely adhere to the upper surface of the filter plate 8. After the extrusion is completed, the filter plate 8 is reset by reversing the motor 11, and a certain resistance is given to the garbage by the inclined surface of the partition plate 3 to prevent the garbage from being driven above the partition plate 3 when the filter plate 8 retracts. Subsequently, it falls above the second filter plate 14. At this time, the liquid inside is continuously discharged by means of gravity, and the next batch of garbage is conveyed back into the box body 1. When the filter plate 8 moves to the right, it will synchronously drive the toothed plate 20 to move by using the L-shaped connecting plate 19. After the toothed plate 20 moves, it drives the gear 17 to rotate. The gear 17 synchronously drives the baffle 16 to rotate by using the rotating shaft 15. After the baffle 16 rotates, the blockage is opened, so that the garbage compressed last time slides into the left side of the second partition plate 13.The liquid is placed on the right side of the second partition plate 13, and then the liquid is transported above the activated carbon filter screen 24 by means of the pump body 22 and the transmission pipe 23 for further treatment. Through the above structure, it is possible to automatically separate the garbage from the liquid after the garbage is squeezed and drained, and collect the garbage, which is convenient for the staff to perform subsequent treatment on the garbage.

[0026] Working principle: The motor 11 drives the threaded rod 12 to rotate synchronously. Since the displacement plate 9 is slidably connected inside the cavity 4, its movement trajectory is restricted. Therefore, when the threaded rod 12 rotates, it will drive the displacement plate 9 to move synchronously. When the displacement plate 9 moves, it will synchronously drive the filter plate 8 to move by using the spring 10. After the filter plate 8 moves and contacts the right inner wall of the box body 1, at this time, when the displacement plate 9 continues to move, it will compress the spring 10 and continue to drive the pressing plate 5 to move. When the pressing plate 5 moves to the inclined surface of the partition plate 3, it will push out the telescopic plate 28 by using the second spring 27, and make the second telescopic plate 28 tightly attached to the upper surface of the filter plate 8. After the extrusion is completed, the filter plate 8 is reset by reversing the motor 11, and a certain resistance is given to the garbage by the inclined surface of the partition plate 3 to prevent the garbage from being driven above the partition plate 3 when the filter plate 8 retracts. Then, it falls above the second filter plate 14. At this time, the liquid inside is continuously drained by means of gravity, and the next batch of garbage is transported into the box body 1 again. When the filter plate 8 moves to the right, it will synchronously drive the toothed plate 20 to move by using the L-shaped connecting plate 19. After the toothed plate 20 moves, it drives the gear 17 to rotate. The gear 17 synchronously drives the baffle plate 16 to rotate by using the rotating shaft 15. After the baffle plate 16 rotates, the blockage is opened, so that the garbage compressed last time slides into the left side of the second partition plate 13, while the liquid is placed on the right side of the second partition plate 13. Then, the liquid is transported above the activated carbon filter screen 24 by means of the pump body 22 and the transmission pipe 23 for further treatment.
