Environmentally-friendly solid waste treatment device based on cyclic crushing technology

Abstract

The invention discloses an environmentally-friendly solid waste treatment device based on a cyclic crushing technology. The environmentally-friendly solid waste treatment device comprises an outer casing body and a crushing cylinder, wherein the outer casing body is internally provide with the crushing cylinder; the crushing cylinder is rotationally connected to the outer casing body through a rotating shaft; the right side end of the rotating shaft penetrates through a side wall of the outer casing body and is fixedly connected to a motor shaft of a first motor; the rotating shaft is rotationally connected to the outer casing body through a first bearing; a plurality of material switching plates are uniformly arranged on the wall of an inner cavity of the crushing cylinder; a crushing rodis arranged in the inner cavity of the crushing cylinder; a plurality of crushing blades matched with the material switching plates are uniformly arranged on the outer cylindrical surface of the crushing rod; according to the invention, through the forward rotation of the first motor, the crushing cylinder is driven to rotate in the forward direction, and when the crushing cylinder rotates, materials falling on the bottom wall of the inner cavity of the crushing cylinder are continuously writhed in the inner cavity of the crushing cylinder under the action of the material switching plates; atthe same time, a second motor is utilized to drive the crushing rod to rotate in the reverse direction and drive the crushing blades to rotate in the reverse direction, and the high-speed rotating crushing blades continuously collide with the writhed materials, thereby ensuring that the materials are fully crushed.

Description

technical field [0001] The invention relates to the field of solid waste treatment equipment, in particular to an environment-friendly solid waste treatment device based on circular crushing technology. Background technique [0002] Solid waste refers to solid, semi-solid, and gaseous items placed in containers that lose their original use value or have not lost their use value but are discarded or abandoned during production, living and other activities. , Articles and substances that are included in waste management according to administrative regulations. Liquid wastes that cannot be discharged into water bodies and gaseous substances placed in containers that cannot be discharged into the atmosphere. [0003] Solid waste refers to the solid and muddy substances discarded by human beings in production and living activities. It is called solid waste, or solid waste for short. Including solid particles separated from waste water and waste gas. All solid or semi-solid sub...

AI Technical Summary

Problems solved by technology

[0004] Existing solid waste crushing devices are usually equipped with crushing knives on the rotating shaft. When solid waste is introduced into the feed port, the solid waste falls freely due to its own gravitational potential energy and keeps in contact with the crushing knives, thereby realizing the crushing of these solid wastes. Crushing and crushing treatment, but the solid waste can only complete one free fall due to the gravitational potential energy, 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 quality is very poor. Usually, it is necessary to repeatedly refill, carry out secondary crushing, or even three crushing to meet the requirements of crushed particles, and the processing effect is greatly reduced.
