Industrial hazardous waste incineration line pretreatment crushing device

Abstract

The invention discloses an industrial hazardous waste incineration line pretreatment crushing device which comprises a crushing cabinet in a rectangular vertical cabinet shape. The crushing assembly comprises rotating shafts, grinding wheels, mounting frames and cutters, the two rotating shafts are symmetrically and rotatably mounted on the two sides of the interior of the crushing cabinet body, the grinding wheels are fixedly connected to the rotating shafts, the two mounting frames are symmetrically and fixedly connected to the interior of the crushing cabinet body and located below the grinding wheels, and the cutters are rotatably arranged in the mounting frames; and the extrusion assembly comprises a fixing frame, a driving machine, air cylinders and a pressing block, a strip-shaped opening is formed in the upper side of the crushing cabinet body, the driving machine is installed in the fixing frame through an adjusting assembly, and the multiple air cylinders are fixedly connected to the lower portion of the driving machine. During use, pressure can be applied to hazardous wastes which cannot be effectively crushed, so that the condition of blockage in the whole crushing process is avoided, and the crushing efficiency of the hazardous wastes is improved.

Description

technical field [0001] The invention relates to the technical field of industrial waste treatment, in particular to a pretreatment and crushing device for an industrial hazardous waste incineration line. Background technique [0002] Wastes with toxic, flammable, corrosive, infectious or strong chemical reactivity or other harmful properties produced in industrial production. Such as electroplating waste slag, waste organic solvent, non-ferrous metal smelting slag, etc. Actual or potential hazards to human health and the environment. The production is relatively concentrated, and the treatment and disposal methods mainly include resource utilization, incineration, solidification, stabilization and landfill. [0003] Combustion line, as a waste incineration device, is a general term for all engineering facilities required for waste treatment processes such as slag discharge, waste heat energy conversion, and purification of generated flue gas after incineration. The incine...

Problems solved by technology

[0005] The purpose of the present invention is to solve the following disadvantages in the prior art. During the crushing process of the crushing device, a large amount of waste will be accumulated above the grinding wheel, resulting in a decrease in the crushing efficiency of the subsequent waste, and the crushing effect is also relatively poor. A proposed pretreatment and crushing device for industrial hazardous waste incineration line
