Industrial and mining hazardous waste stabilization and solidification treatment equipment

Abstract

The invention relates to industrial and mining hazardous waste stabilization and solidification treatment equipment. The equipment comprises a barrel body, a barrel cover, an outer spiral blade and aninner spiral blade, wherein an interlayer is arranged inside the barrel wall of the barrel body, and the interlayer is filled with ceramic heating sheets; the ceramic heating sheets are connected with a temperature controller to control heating, and the temperature controller is further connected with a temperature sensor; curing agent nozzles are arranged at the bottom of the barrel cover, and the outer ends of the curing agent nozzles are connected with storage tanks; a feeding hopper is fixed on the right barrel wall of the barrel body, and a discharging hole is formed in the left barrel wall of the barrel body; a rotating cylinder is arranged at the bottom of the barrel body, and the rotating cylinder extends out of the barrel cover to be provided with an organic rare earth adding hopper; the outer spiral blade is fixed to the outer wall of the rotating cylinder, a horizontal stirring rod is arranged at the position, close to the bottom of the barrel body, of the outer spiral blade, and openings distributed at equal intervals are formed in the outer wall of the outer spiral blade; and a rotating shaft is arranged on the inner side part of the rotating cylinder and provided with the inner spiral blade. The industrial and mining hazardous waste stabilization and solidification treatment equipment is simple in structure, the treatment cost is reduced, stabilization and solidification treatment can be carried out at the same time, and the stabilization and solidification uniformity is improved.

Description

technical field [0001] The invention relates to the technical field of industrial waste treatment, in particular to a stable solidification treatment equipment for industrial and mining hazardous waste. Background technique [0002] Industrial and mining solid waste refers to various waste residues, dust and other wastes discharged by industrial and mining enterprises during production activities. With the development of industrial production, the amount of hazardous waste produced by industrial and mining enterprises is increasing day by day. There are more and more by-products, among which waste ash is one of the main by-products, and landfill treatment can no longer meet the treatment needs. Therefore, stabilization and solidification have become one of the important means for industrial and mining enterprises to deal with waste ash. [0003] Hazardous waste ash solidification treatment is to use physical or chemical methods to mix harmful ash with some inert substrates t...
