Solid waste treating and crushing device

Abstract

The invention relates to the field of environmental protection and particularly discloses a solid waste treating and crushing device. The solid waste treating and crushing device comprises a shell, acrushing motor, a feeding opening, a collecting tank, wherein vertical rollers are coaxially and fixedly mounted on a transmission shaft; crushing cylinders are arranged on the outer sides of the crushing rollers and are matched with the crushing rollers; the crushing rollers comprise a first crushing roller and a second crushing roller which are coaxially and integrally arranged; the crushing cylinders comprise a first crushing cylinder and a second crushing cylinder; the first crushing cylinder and the second crushing cylinder are respectively and correspondingly matched with the first crushing roller and the second crushing roller; the distance between the first crushing cylinder and the first crushing roller is gradually reduced from top to bottom; and the collecting tank is arranged under a sieving net. According to the solid waste treating and crushing device, two crushing rollers and the crushing cylinders matched with the crushing rollers are arranged, so that the raw materialcrushing gap is gradually reduced from top to bottom; the raw materials are broken from large to small; the solid wastes are rapidly discharged; the increase of the motor load can also be avoided; andthe solid wastes can be safely and stably crushed.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to solid waste treatment and crushing equipment. Background technique [0002] There are many classifications of solid waste: according to the source, it can be divided into mining waste, industrial waste, municipal waste, agricultural waste and radioactive waste; (sludge); according to chemical properties, it can be divided into organic waste and inorganic waste; according to the degree of hazard, it can be divided into hazardous waste and general waste. For the treatment of solid waste, large-scale crushing devices are usually used to crush the waste. The crushing of solid waste is the process of changing solid waste from large to small. External force is used to overcome the cohesive force between the solid waste material points to split large solid waste into small pieces. the process of. Existing solid waste crushing devices are usually equipped with one or more rotati...

AI Technical Summary

Problems solved by technology

Existing solid waste crushing devices are usually equipped with one or more rotating shafts driven by motors inside the crushing device, and multiple groups of crushing knives with different structures and functions are arranged on the rotating shafts. , the solid waste falls freely due to its own gravitational potential energy, and is in constant contact with the crushing tool. The crushing tool rotates rapidly under the drive of the rotating shaft, and uses collision, extrusion, shearing, and cutting to realize the crushing and crushing of these solid wastes. However, the solid waste Due to the gravitational potential energy, the waste can only complete one free fall, and has only a short contact time with the crushing tool. Some waste may have fallen into the bottom of the crushing device before contacting the crushing tool, and the crushing efficiency will be reduced.

[0003] Chinese patent (publication number: CN 109453869 A) discloses a crushing device for continuous processing of fixed waste garbage, which is crushed through a horizontal crushing cylinder to make solid waste move horizontally for crushing, but such horizontal crushing is prone to deformation and dislocation after long-term use , reduce the practical life of the equipment
