Description

Technical Field

[0001] This utility model relates to the field of waste treatment, and in particular to an automatic drainage device for leachate grating plates in waste pits. Background Technology

[0002] Waste incineration is a process in which waste is reduced in volume through appropriate thermal decomposition, combustion, and melting reactions at high temperatures, becoming residue or molten solid matter. Currently, waste-to-energy plants provide a new method for urban waste management, achieving the harmlessness, resource recovery, and volume reduction of waste. In existing waste-to-energy plants, waste is stored in storage ponds. These ponds are generally flat-bottomed deep pits with leachate channels.

[0003] The leachate outlet is located on the wall beside the leachate ditch, and a grating is installed at the outlet to block debris. When the grating holes for leachate drainage become blocked by debris, the holes need to be cleared.

[0004] Patent CN109051429A discloses a self-draining leachate grating system for garbage pits. The system includes a leachate grating, a drainage system actuator that works in conjunction with the grating, and a hydraulic cylinder that controls the actuator's movement. The drainage system actuator includes a guide column and a slide block. The guide column is mounted on the slide block, which is mounted on a guide rod and can slide along the guide rod, driving the guide column to clear the leachate grating. One end of the guide rod is connected to the leachate grating, and the other end is mounted on a slide block mounting base, which is mounted on a support frame. The self-draining leachate grating system uses a hydraulic cylinder to push the slide block reciprocating along the guide rod. The guide column on the slide block clears the holes in the grating. The guide column is mounted on the slide block with a nut (double nut). Regarding the aforementioned technology, the inventor believes that replacing the guide column is inconvenient, as disassembling and tightening the nuts takes a significant amount of time, and prolonged exposure to harsh environments poses safety hazards to workers. Improvements are needed. Utility Model Content

[0005] In order to improve the replacement efficiency of the grating and eliminate safety hazards, this application provides an automatic dredging device for leachate grating in garbage pits.

[0006] The automatic dredging device for leachate grating in landfills provided in this application adopts the following technical solution:

[0007] An automatic dredging device for leachate grating in a landfill includes a main mounting plate, mounting columns installed at the four corners of the main mounting plate, a dredging assembly mounted on the mounting columns, and a drive assembly mounted on the main mounting plate. The dredging assembly includes a sliding plate slidably connected to the mounting columns, a plurality of dredging columns mounted on the sliding plate, and a fixing assembly mounted on the sliding plate. The sliding plate has through holes for the dredging columns to pass through. The fixing assembly includes a fixing rod, a fixing plate, and fixing bolts. Each dredging column has a fixing hole for the fixing rod to pass through, and the fixing rod abuts against the side of the sliding plate closest to the main mounting plate. The fixing bolts fix the fixing plate to the sliding plate. Each dredging column has a mounting ring at its end near the sliding plate, and a disassembly plate is provided on the side of the sliding plate away from the main mounting plate. The disassembly plate allows the dredging column to pass through, and its two sides abut against the sliding plate and the mounting ring, respectively.

[0008] By adopting the above technical solution, the fixing component strings together the same row of dredging columns via fixing rods, and fixes the dredging columns to the sliding plate via fixing plates and fixing bolts. Thus, when the driving component moves the sliding plate, the dredging columns can be inserted into the holes of the grating plate for dredging. When replacing the dredging columns, since several dredging columns are inserted into the disassembly plate, to remove the dredging columns, first release the fixing component from the dredging columns, then use equipment to move the disassembly plate away from the sliding plate. Due to the action of the mounting ring, all dredging columns are carried away from the sliding plate by the disassembly plate. Then, the disassembly plate is moved upwards to complete the disassembly. Similarly, when installing new dredging columns, the dredging columns are pre-installed on the disassembly plate, then the disassembly plate is moved to a position close to the sliding plate by equipment, and finally, the fixing component fixes the dredging columns to the sliding plate. This automatic dredging device for leachate grating plates in garbage pits can completely disassemble (or install) the dredging columns, greatly saving replacement time, improving the replacement efficiency of the dredging columns, and eliminating safety hazards.

[0009] Preferably, the side of the disassembly plate away from the sliding plate is provided with an anti-detachment plate, which abuts against the mounting ring.

[0010] By adopting the above technical solution, the anti-detachment plate is set to prevent the drain column from being pushed by the sliding plate when it is installed on the sliding plate, thereby avoiding the drain column from falling off the disassembly plate and affecting the overall installation; the anti-detachment plate and the disassembly plate work together to ensure that the drain column is in a whole during disassembly and installation, which is convenient for moving by equipment.

[0011] Preferably, the sliding plate has a through hole for the unblocking column to pass through, the side wall of the unblocking column has a positioning protrusion, and the wall of the through hole has a positioning groove for the positioning protrusion to be accommodated. When the positioning protrusion is accommodated in the positioning groove, the depth direction of the fixing holes on the unblocking columns is horizontal.

[0012] By adopting the above technical solution, and by setting positioning protrusions and positioning grooves in combination, after replacing the unblocking column, the new unblocking columns will have the same orientation of the fixing holes in the same row due to the positioning of the positioning protrusions, which makes it easy to insert fixing rods to initially fix the unblocking columns.

[0013] Preferably, the sliding plate is provided with a positioning block, and the fixing plate is provided with a positioning groove for the positioning block to pass through.

[0014] By adopting the above technical solution, a positioning groove is set for the positioning block to pass through, and the fixing plate can be quickly attached to the sliding plate. Then, the fixing plate can be fixed by fixing bolts, thereby completing the further fixation of the unblocking column.

[0015] Preferably, the positioning block has installation chamfers at the two corners near the main mounting plate.

[0016] By adopting the above technical solution, the installation chamfer facilitates the insertion of the positioning block into the fixing plate, and the fixing plate is quickly positioned so that the fixing bolts can fix the fixing plate.

[0017] Preferably, the fixing plate has a limiting groove, which corresponds to the unblocking column. The end of the unblocking column is inserted into the limiting groove, and a buffer pad is provided on the bottom of the limiting groove. The end face of the unblocking column abuts against the buffer pad.

[0018] By adopting the above technical solution, a buffer pad is set to abut against the drain column. During the draining process, the drain column will exert a large force on the fixed plate. The buffer pad can play a buffering role to protect the drain column and the fixed plate and prevent excessive damage to the fixed plate and the drain column.

[0019] Preferably, the fixing plate has a clearance groove for accommodating the fixing rod.

[0020] By adopting the above technical solution, a clearance groove is set up to accommodate the fixing rod, which serves to occupy and protect it, preventing the fixing rod from being directly pressed against the side wall of the fixing plate and damaged during dredging.

[0021] Preferably, the drive assembly includes a threaded screw rotatably connected to the main mounting plate and a drive motor disposed on the main mounting plate, the drive motor driving the threaded screw to rotate, and the sliding plate being threadedly connected to the threaded screw.

[0022] By adopting the above technical solution, the drive motor drives the threaded screw to rotate, thereby moving the sliding plate and causing the unblocking column on the sliding plate to approach the grid plate and unblock the grid plate holes.

[0023] Preferably, the main mounting plate is provided with a mounting base, the mounting base is provided with a reduction gearbox, the drive motor is located on the side of the reduction gearbox away from the main mounting plate, the output shaft of the drive motor is fixed to the input end of the reduction gearbox, and the output end of the reduction gearbox is fixed to the threaded screw.

[0024] By adopting the above technical solution, a reduction gearbox is set to reduce the speed of the drive motor, so that the speed of the drive motor can drive the screw to rotate at a low speed to move the sliding plate.

[0025] The main technical effects of this utility model are reflected in the following aspects:

[0026] 1. This utility model can efficiently replace the drain cleaning column, saving time and eliminating safety hazards;

[0027] 2. This utility model sets a buffer pad to abut against the drain column. The buffer pad can play a buffering role to protect the drain column and the fixing plate and prevent excessive damage to the fixing plate and the drain column.

[0028] 3. This utility model features a chamfered installation angle to facilitate the insertion of the positioning block into the fixing plate, thereby enabling quick fixing of the fixing plate after replacing the unblocking column and improving work efficiency. Attached Figure Description
