Description

Technical Field

[0001] The present application relates to the field of fly ash processing equipment, and in particular to a fly ash solidification device. Background Art

[0002] Fly ash produced by the incineration of domestic waste contains organic pollutants such as benzopyrene, benzanthracene, dioxins, and heavy metals such as Cr, Cd, Hg, Pb, Cu, and Ni, and is a highly hazardous solid waste. Dioxins are chlorinated tricyclic aromatic hydrocarbon organic compounds with multiple toxic effects, which are irreversible teratogenic, carcinogenic, and mutagenic; Hg and its compounds are extremely neurotoxic and can cause serious damage to multiple organs of the human body. If fly ash is not properly disposed of, it will cause serious harm to the environment.

[0003] At present, the most common harmless disposal method for incineration fly ash, a hazardous waste, is landfill. Since fly ash contains a large amount of heavy metal inorganic salts, the heavy metal content in its leachate far exceeds the standard and cannot be directly disposed in hazardous waste landfills. Solidification is usually used to solidify the heavy metal and dioxin components in the fly ash to prevent the heavy metals, dioxins and other components from entering the leachate during the leaching process, so that the fly ash meets the standard entry requirements.

[0004] The existing dust removal equipment is relatively old and the design is not perfect. When removing dust, it is easy to generate a lot of dust in the entire fly ash room, especially when the fly ash enters the mixer, there will be a phenomenon of fly ash coming out, which is further not conducive to the stable treatment of fly ash, and the environmental protection performance has been reduced, so it needs to be improved. Summary of the invention

After the driven rotating rod drives the missing gear to rotate, the connecting rack meshing with the missing gear drives the reciprocating frame to move back and forth along the height direction of the ash hopper, so that the large particles of impurities accumulated on the upper surface of the filter plate are shaken, thereby effectively reducing the occurrence of large particles accumulating on the filter plate and causing the filter plate to be blocked.

[0017] Preferably, an auxiliary plate is provided at the inner wall of the ash hopper, the auxiliary plate is provided with a make way groove, a lifting rod is provided in the make way groove, the lifting rod can slide in the make way groove, the lifting rod is connected to the reciprocating frame, an elastic member is sleeved on the outer wall of the lifting rod, one end of the elastic member is connected to the reciprocating frame, and the other end of the elastic member is connected to the auxiliary plate.

[0018] By adopting the above technical solution, when the filter plate continuously rises or falls along the height direction of the ash hopper, the lifting rod slides in the clearance groove, and the elastic member is compressed under the drive of the lifting rod, so that the filter plate is more stable when it moves back and forth.
