Description

Technical Field

[0001] The invention relates to a slag discharge system for solid waste treatment equipment, belonging to the technical field of solid waste treatment devices. Background Art

[0002] At present, the most commonly used method of slag removal for solid waste treatment equipment is manual slag removal, which involves manually removing the ash from the furnace and then sealing it. This method not only has low slag removal efficiency, but also high labor costs and poses a potential threat to the health of workers. In addition, the temperature of the slag is as high as 300°-600°. If the developed automatic slag removal cannot reasonably isolate and cool the slag, it will pose a threat to the safety of the operating workers and the safety of the treatment site. Summary of the invention

[0003] Aiming at the problems that the potential safety hazard of slag removal equipment is too high and dust pollution is serious when workers remove ash and slag, the present invention provides a slag removal system for solid waste treatment equipment.

[0004] The technical solution of the present invention to solve the above technical problems is as follows: A slag discharge system for solid waste treatment equipment, characterized in that it includes a slag receiving pool unit, a slag removal power unit and a waste slag transport unit assembled together; the top of the slag receiving pool unit is open, and the slag removal power unit and the waste slag transport unit are equipped with a sealed shell. The slag receiving pool unit is installed at the bottom of the combustion furnace, and the waste slag formed after the combustion of the combustion furnace falls into the slag receiving pool. The slag removal power unit and the waste slag transport unit are equipped with a sealed shell to prevent the dust generated by the fallen waste slag from spreading and ensure a clean environment.

[0005] On the basis of the above technical solution, in order to achieve the convenience of use and the stability of the equipment, the present invention can also make the following improvements to the above technical solution:

[0006] Furthermore, the waste slag collection unit includes a groove-shaped outer frame, two parallel supporting beams are installed in the groove of the outer frame, the grille group is fixed above the supporting beams, a slag receiver inlet is opened on the side wall of the outer frame on one side of the grille group, and a limit column is installed on the other side of the grille group, the limit column is installed close to the grille group, and the inlet is located below the bottom surface of the grille group; the grille group includes a square frame surrounded by side panels, the side panels are connected to the supporting beams through supporting columns, and the connection method can be welding or bolt fixing connection, and a plurality of heat insulation bars are installed in the square frame surrounded by the side panels, and the heat insulation bars include a flat plate and an inclined plate connected as a whole, which can be welded or integrally bent, and the angle between the inclined plate and the flat plate is an obtuse angle. The inclined plate of the heat insulation bar can play a buffering role, and the horizontal plate can further reduce the falling speed of the waste slag. A high-aluminum fiber blanket is pasted on the heat insulation bar to block the radiant heat of the ash.

[0007] Furthermore, a protective plate is installed between the upper edge of the inlet and the bottom end of the grid group. The protective plate can prevent the waste slag of the slag receiving pool unit from directly falling into the slag removal power unit. The slag removal power unit and the slag receiving pool unit are connected at the inlet.

[0008] Furthermore, the slag removal power unit includes an outer cover, a pair of parallel tracks are installed in the outer cover, a horizontal axis is installed at the front and rear ends of the track, both ends of each horizontal axis pass through the track and a gear is installed at both ends of the horizontal axis, and the two gears on the same track are connected by a chain; the motor is installed in the cavity between the side of a track and the side wall of the outer cover, and a right-angle reducer is installed at the output end of the motor, and the output end of the right-angle reducer is connected to the end of a horizontal axis through a coupling. The motor drives the horizontal axis, so that the gear and chain move, and then drives the movement of the slag collector.

[0009] Furthermore, a slag collector is installed between the two tracks. The slag collector includes an outer frame composed of an angle steel-shaped front scraper, side beams and a bottom beam. The outer frame is provided with crisscrossing cross beams and longitudinal beams. A pulley frame and a chain frame are installed at each end of the bottom beam. A supporting wheel and a ratio wheel are installed on the pulley frame, and the supporting wheel and the ratio wheel are placed in the grooves on the opposite sides of the track. The chain frame is located below the track and connected to the chain. The supporting wheel and the ratio wheel are two small wheels installed perpendicular to each other. The supporting wheel plays the role of supporting the slag collector to facilitate the sliding of the slag collector along the track. The ratio wheel is used to limit the position of the slag collector between the two tracks to prevent the slag collector from shaking. In order to better stabilize the movement of the slag collector, a pair of pulley frames with supporting wheels and ratio wheels are installed at the front end of the collector (i.e., the end close to the front scraper).

[0010] Furthermore, a limit switch is installed at the front end and the rear end of the side beam, so that two limit switches are installed at the front and rear ends of the slag removal power unit, and the stop position of the slag remover in and out is accurately controlled by the limit switches.

[0011] Furthermore, a drag chain rack is installed on each of the two tracks. The upper part of the chain ring is on the drag chain rack, which can solve the problem that the upper chain sinks due to the weight of the drag chain, affecting the service life of the chain. It is also convenient for maintenance. When the chain is disconnected during maintenance, the chain will not fall due to its own weight.

[0012] Furthermore, a slag collector outlet and a transport port are provided on the side wall of the outer cover, and a motor maintenance port is provided on the top surface of the outer cover. The slag collector outlet cooperates with the inlet on the outer frame.

[0013] Furthermore, the waste slag transport unit includes a plate chain conveyor and a plate chain conveyor leg supporting the plate chain conveyor, the plate chain conveyor includes a horizontal section and a transport section, the horizontal section is placed under the track, the transport section is located on the outside of the outer cover, a transport shield is installed on the outside of the transport section, and the transport shield is supported by the shield legs.

[0014] Furthermore, a leg pull rod is installed between the shield legs; the plate chain conveyor legs are telescopic legs, and the height can be adjusted. If the ground is uneven, the leg height can be adjusted to achieve leveling.

[0015] The advantages of the present invention are that the equipment is fully enclosed, achieving human-machine isolation and solving the problem of possible harm to operators caused by high-temperature waste residue. BRIEF DESCRIPTION OF THE DRAWINGS
