Description
Technical Field
[0001] The utility model patent belongs to the technical field of solid waste treatment equipment, and specifically relates to a material discharge device for a decomposition furnace to treat solid waste. Background Art
[0002] With the rapid development of social economy, a large amount of waste generated in the production process of life cannot be effectively and timely disposed of, causing serious environmental pollution, economic losses and endangering the health of residents. Therefore, as the national environmental control measures are gradually strengthened, a large number of industrial wastes produced by enterprises will be uniformly collected and treated by qualified disposal enterprises. Waste includes: industrial solid waste, hazardous waste, medical waste, contaminants, mineral oil, etc. At present, my country's hazardous waste management mainly achieves harmless disposal and resource utilization through recycling, incineration, landfill and cement kiln coordination. Among them, cement kiln coordinated disposal is known as the safest and most thorough hazardous waste disposal method with its wide disposal range, large disposal volume, strong disposal capacity, full resource utilization, good environmental benefits, low investment and low operating cost. In recent years, it has become the mainstream of hazardous waste disposal; but there are many types of solid waste. For the cement kiln coordinated disposal of solid waste process, the biggest challenge is that the solid waste entering the kiln will affect the thermal environment in the kiln.
[0003] Therefore, before entering the decomposition furnace, the way of unloading solid waste is crucial. In the prior art, for the sake of production efficiency, enterprises will set up conveying devices such as plate feeders, belt conveyors, and reamers between the waste treatment device and the decomposition furnace, and use these conveying devices to transport and unload the pre-treated solid waste. However, the inventors found that during the transportation process, the unloading ports of each conveying device will be blocked, materials will be suspended, and the plate chains and belts will be blocked, which often requires manual dredging. These blocked materials are very easy to condense into agglomerates, resulting in their inability to be completely burned after entering the decomposition furnace, thereby affecting the thermal environment in the furnace. At the same time, during the transportation and manual dredging process of the plate feeder and belt conveyor, the solid waste will generate dust due to vibration, thereby polluting the workshop environment.
