Description

Technical Field

[0001] This application relates to the technical field of landfill leachate treatment equipment, and in particular to a landfill leachate full-volume treatment equipment. Background Technology

[0002] CN217593952U discloses "a full-volume treatment device for leachate from a waste transfer station, including a cylindrical separation cylinder, in which a support plate is fixed...the piston rod of the cylinder is fixedly connected to the baffle". This utility model uses a turning mechanism to evenly turn and spread the waste mixture on the holding tray. The blowing force generated by the air shower fan will cause the leachate on the surface of the solid slag to move downward. The leachate adhering to the entire surface of the solid slag in the waste mixture will be very small, which makes it easy to collect the leachate in one go.

[0003] In the aforementioned patent, after a single collection of landfill leachate is completed, the solid residue inside the separation cylinder needs to be manually removed by opening the slag discharge door. This not only makes the removal difficult and increases labor intensity, but also reduces the overall efficiency of landfill leachate collection. Therefore, a landfill leachate full-volume treatment device is proposed to solve the above problems. Utility Model Content

[0004] To address the problem that after a landfill leachate collection is completed, it is necessary to open the slag discharge door and manually remove the solid slag inside the separation cylinder, which is not only difficult to remove and increases labor intensity, but also reduces the overall landfill leachate collection efficiency, this application provides a landfill leachate full-volume treatment device.

[0007] A slag discharge door is installed on the outer wall of the processing box away from the cylinder. A sealing block is fixedly connected to the outer wall of the slag discharge door. The sealing block is adapted to be inserted into the end of the separation cylinder. An actuator for driving the slag discharge door to open and close is installed on the outer wall of the processing box.

[0008] Preferably, the actuator includes multiple bearings fixedly connected to the outer walls of both sides of the processing box. One end of each bearing is rotatably connected to a synchronous pulley via a bearing. A transmission belt is installed on the outer walls of every two adjacent synchronous pulleys. Threaded rings are fixedly connected to the outer walls of the shafts of the two synchronous pulleys located above the processing box. A secondary gear is fixedly connected to the end of the threaded ring away from the synchronous pulley.

[0009] Preferably, the actuator further includes multiple screws fixedly connected to the outer wall of the slag discharge gate by multiple fixing blocks. The multiple screws correspond to multiple bearing seats and pass through the bearing seats, bearings, synchronous pulleys, threaded rings and auxiliary gears in sequence. The screws are threadedly connected to the inner wall of the threaded rings.

[0010] Preferably, mounting brackets are fixedly connected to both outer walls of the processing box, and a servo motor is fixedly installed on one outer wall of the mounting bracket.

The guide plate will guide the leachate to the outlet for discharge, making it easy to collect the leachate in one go.

[0015] 2. The actuator can drive the slag discharge door forward, causing the sealing block to disengage from the end of the separation cylinder. At this time, the cylinder drives the squeezing block to continue moving forward, which can push the solid slag in the separation cylinder out of the treatment box and discharge it in one go. Compared with the existing technology, there is no need for manual cleaning, which facilitates the next collection operation of landfill leachate and improves the overall collection efficiency.

[0021] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0022] This application discloses a comprehensive landfill leachate treatment device. (Refer to...) Figure 1-4 A landfill leachate full-volume treatment device includes a treatment tank 1, a separation cylinder 4 fixedly connected to the inner wall of the treatment tank 1, a filter screen 5 provided on the bottom outer wall of the separation cylinder 4, an extrusion block 6 installed on the inner wall of the separation cylinder 4, and a cylinder 8 fixedly installed on one side outer wall of the treatment tank 1 through a bracket 7. The output shaft of the cylinder 8 passes through the treatment tank 1 and is fixedly connected to the extrusion block 6.

[0023] A slag discharge door 9 is installed on the outer wall of the processing box 1 on the side away from the cylinder 8. A sealing block 23 is fixedly connected to the outer wall of the slag discharge door 9. The sealing block 23 is adapted to be inserted into the end of the separation cylinder 4. An actuator for driving the opening and closing of the slag discharge door 9 is installed on the outer wall of the processing box 1.

[0024] The actuator includes multiple bearing seats 12 fixedly connected to the outer walls of both sides of the processing box 1. One end of the bearing seat 12 is rotatably connected to a synchronous pulley 14 via a bearing 13. A transmission belt 15 is installed on the outer wall of every two adjacent synchronous pulleys 14. A threaded ring 16 is fixedly connected to the outer wall of the shaft of the two synchronous pulleys 14 located above the processing box 1. A secondary gear 17 is fixedly connected to the end of the threaded ring 16 away from the synchronous pulley 14.

[0025] The actuator also includes multiple screws 11 fixedly connected to the outer wall of the slag discharge gate 9 by multiple fixing blocks 10. The multiple screws 11 correspond to multiple bearing seats 12 and pass through the bearing seats 12, bearings 13, synchronous pulleys 14, threaded rings 16 and auxiliary gears 17 in sequence. The screws 11 are threadedly connected to the inner wall of the threaded rings 16.

[0026] Mounting brackets 18 are fixedly connected to the outer walls of both sides of the processing box 1. A servo motor 22 is fixedly mounted on one side of the outer wall of the mounting bracket 18. The output shaft of the servo motor 22 passes through the mounting bracket 18 and is fixedly connected to a main gear 19. The main gear 19 meshes with the auxiliary gear 17.

[0027] The top outer wall of the processing tank 1 is provided with a feed inlet 2, which is connected to the inner cavity of the separation cylinder 4. The bottom outer wall of the processing tank 1 is provided with a liquid outlet 3. A guide plate 21 is fixedly connected to the inner wall of the processing tank 1 below the separation cylinder 4. The downward inclined end of the guide plate 21 is located above the liquid outlet 3.

[0028] Multiple support legs 20 are fixedly connected to the bottom outer wall of the processing box 1, and the multiple support legs 20 are evenly distributed at the four corner edges of the processing box 1.

[0029] The implementation principle of the landfill leachate full-volume treatment device in this application embodiment is as follows: When in use, the landfill mixture is added into the separation cylinder 4 through the feed port 2, and then the cylinder 8 is started. The output end of the cylinder 8 drives the extrusion block 6 to move forward in the separation cylinder 4. The extrusion block 6 pushes the landfill mixture to move until it hits the sealing block 23. As the extrusion block 6 continues to extrude, the landfill leachate on the surface of the solid slag will flow through the filter screen 5 to the guide plate 21. The guide plate 21 guides the landfill leachate to the outlet 3 for discharge, which facilitates the one-time collection of landfill leachate.

[0030] After one collection is completed, the actuator starts two servo motors 22. The output shafts of the two servo motors 22 drive two main gears 19 to rotate synchronously in the same direction. The two main gears 19 then drive the two auxiliary gears 17 meshing with them to rotate. The two auxiliary gears 17 then drive two synchronous pulleys 14 to rotate through threaded rings 16. At this time, the two synchronous pulleys 14 drive the two synchronous pulleys 14 below the processing box 1 to rotate synchronously through the transmission belt 15. In this way, multiple synchronous pulleys 14 rotate synchronously in the same direction at the end of the bearing seat 12 through the bearing 13. At the same time, multiple threaded rings 16 rotate on the threads of multiple screws 11. The threaded rings 16 drive multiple screws 11 to move. The multiple screws 11 then drive the slag discharge door 9 to move through the fixing block 10. The slag discharge door 9 drives the sealing block 23 to open the end of the separation cylinder 4. The cylinder 8 is started again, so that the squeezing block 6 pushes the solid slag out of the processing box 1 to facilitate the subsequent collection of landfill leachate.
