Technical Field

[0001] The utility model relates to the technical field of slag transportation, in particular to a garbage power generation slag transportation device. Background Art

[0002] In recent years, with the advancement of urbanization, the large amount of domestic waste generated by citizens has put forward high requirements for urban waste disposal. Waste incineration power generation is an economical and affordable way of waste disposal. It has the advantages of large-scale and sustainable waste disposal, and the electricity generated by combustion can also generate economic benefits.

[0003] When an incinerator is used to incinerate garbage to generate electricity, slag will be produced in the furnace. The slag will be discharged outward through the discharge port of the incinerator and then transported by a screw conveyor. Since the discharged slag may be mixed with large particles of impurities, if the large particles are not filtered, the large particles of impurities may damage the blades of the screw conveyor, and may also cause the screw conveyor to be in an abnormal state and difficult to transport normally, which brings inconvenience to the actual slag transportation.
