Description

Technical Field

[0001] The invention relates to the technical field of leachate treatment, and in particular to a garbage bin leachate dredging device and method. Background Art

[0002] The treatment of leachate from garbage bins is a key link in the garbage disposal process. The leachate contains a large amount of impurities and solid particles, and needs to be filtered using a filter plate. Since the filter holes of the filter plate are easily clogged by fine particles, the filter holes of the filter plate need to be cleared regularly to ensure the filtering efficiency of the filter plate.

[0003] The existing filter plate unclogging device specifically simply utilizes a translational unclogging rod to penetrate the filter holes of the filter plate to unblock the filter plate, but this method is difficult to effectively remove the blockages tightly attached to the filter holes, and the unclogging effect is poor. Moreover, the existing unclogging device lacks the cleaning function of the unclogging rod, and the blockages are easily attached to the unclogging rod, affecting the subsequent unclogging effect. Summary of the invention

[0004] In view of this, the present invention provides a garbage bin leachate dredging device and method.

[0005] The technical implementation scheme of the present invention is: a garbage bin leachate dredging device, comprising a filter plate with filter holes, a movable frame that moves forward and backward is provided on the left side of the filter plate, a slide plate that slides left and right and is driven by an electric push rod is provided on the movable frame, a plurality of rows of dredging rods corresponding to the filter holes are rotatably connected to the slide plate, a gear box for driving the dredging rods to rotate is installed on the slide plate, a fixed frame is connected to the right side of the movable frame, swinging tubes rotatably connected to the fixed frame are provided between two adjacent rows of dredging rods, a swinging mechanism for swinging the swinging tube is provided on the movable frame, and a row of high-pressure nozzles are installed on the swinging tube.

Under the action of the spring, the contact part of the contact plate extends into the square groove along the triangular groove to locate the position of the dredging rod so that the dredging rod can dredge the filter holes smoothly.

[0015] 3. After the high-pressure nozzle flushes the surface of the dredging rod, the dredging rod passes through the through hole, and the cleaning ring cleans the small amount of remaining impurities on the surface of the dredging rod, further improving the cleaning effect.

The ends of the two contact plates 92 away from each other are contact portions that cooperate with the square groove 95.

[0032] The leachate in the garbage bin is filtered through the filter plate 1. When the filter plate 1 needs to be dredged, under the transmission action of the gear box 5, the drive motor is controlled to rotate the dredging rod 4, and at the same time, the electric push rod 31 is controlled to drive the slide plate 3 to move right, driving the gear box 5 and the dredging rod 4 to move right together, and the tapered end 41 passes through the filter hole. The electric push rod 31 is controlled to make the slide plate 3 and the dredging rod 4 move back and forth left and right, and the dredging rod 4 rotates and moves at the same time, so that the dredging rod 4 can efficiently dredge the filter hole.

[0033] High-pressure water is introduced into the water inlet pipe 71, and the water is sprayed out from the high-pressure nozzle 8 after passing through the hose 72 and the swing pipe 7 to flush the filter hole and the surface of the dredging rod 4. The servo motor is controlled to drive the rotating shaft 87 to rotate, and the rotating shaft 87 drives the disc 88 to rotate. Since the eccentric block 89 is located in the long hole 2 86, the eccentric block 89 at the eccentric position of the disc 88 can make the connecting plate 85 move back and forth up and down, driving the lifting rod 81 and the pushing block 82 to move back and forth up and down. The pushing block 82 that moves back and forth up and down pushes the connecting block 83 to swing back and forth up and down through the long hole 1 84, driving the swing pipe 7 and the high-pressure nozzle 8 to swing back and forth up and down, expanding the flushing range of the high-pressure water, and more effectively flushing the filter hole and the dredging rod 4, thereby flushing away the blockage in the filter hole and improving the dredging effect.

[0034] Initially, the spring is in a stretched state, and the right end of the contact rod 91 abuts against the left outer wall of the gear box 5. When the next filter plate 1 needs to be dredged, the electric roller 23 is controlled to rotate, and the electric roller 23 moves in the front-to-back direction along the guide groove, driving the moving frame 2, the slide plate 3, the dredging rod 4, the gear box 5, the fixing frame 6, the swing pipe 7, the water inlet pipe 71 and the high-pressure nozzle 8 to move forward and backward as a whole to the left of the next filter plate 1; then the electric push rod 31 is controlled to move the slide plate 3, the gear box 5 and the dredging rod 4 to the right. During the dredging operation, the contact rod 91 and the contact plate 92 can be moved to the right relative to the movable frame 2 under the action of the spring, and the contact portion of the contact plate 92 extends into the square groove 95 along the triangular groove 94, so that the contact rod 91, the movable frame 2, the slide plate 3 and the dredging rod 4 are positioned in the front-to-back direction through the contact plate 92, ensuring that the dredging rod 4 can be accurately aligned with the filter hole and avoiding the position deviation of the dredging rod 4, so that the dredging rod 4 can smoothly dredge the filter hole, thereby realizing the dredging of different filter plates 1.

[0035] Example 2: Based on Example 1, refer to Figure 1 , Figure 2 and Fig.10 The garbage bin leachate dredging device also includes a connecting frame 101 and a cleaning ring 102. The right part of the movable frame 2 is bolted with the connecting frame 101 located on the right side of the high-pressure nozzle 8. The connecting frame 101 is provided with through holes in an array that correspond to the dredging rods 4 one by one. The connecting frame 101 is connected to the cleaning ring 102 for cleaning the dredging rods 4 at the through holes. In the present embodiment, the cleaning ring 102 is made of sponge.

[0036] After the high-pressure nozzle 8 flushes the surface of the dredging rod 4, the dredging rod 4 continues to move left and right, and the dredging rod 4 will pass through the through hole. The cleaning ring 102 can clean the small amount of remaining impurities on the surface of the dredging rod 4, further improving the cleaning effect and ensuring the effect of the next use of the dredging rod 4.

[0037] A method for dredging leachate from a garbage bin, comprising the following steps: S1: The filter plate 1 filters the leachate. When the filter plate 1 needs to be dredged, under the action of the gearbox 5, the driving motor is controlled to rotate the dredging rod 4, and at the same time, the electric push rod 31 is controlled to move the slide plate 3, the gearbox 5 and the dredging rod 4. The dredging rod 4 dredges the filter holes through the conical end 41. S2: The high-pressure nozzle 8 sprays water to wash the filter holes and the surface of the dredging rod 4. The servo motor is controlled to rotate the rotating shaft 87 and the disc 88. The eccentric block 89 makes the connecting plate 85, the lifting rod 81 and the pushing block 82 move up and down reciprocally, so that the connecting block 83, the swing pipe 7 and the high-pressure nozzle 8 swing up and down reciprocally, expanding the washing range. S3: Control the electric roller 23 to move along the guide groove, so that the moving frame 2, the dredging rod 4 and the high-pressure nozzle 8 move to the due left of the next filter plate 1. Control the electric push rod 31 to move the dredging rod 4 to dredge the filter holes. Under the action of the spring, the contact part of the contact plate 92 extends into the square groove 95 along the triangular groove 94, so that the dredging rod 4 is aligned with the filter holes.
