Description

A shearing and crushing device for solid waste treatment capable of collecting fines

technical field

The invention belongs to the technical field of solid waste treatment, in particular to a shearing and crushing device for solid waste treatment capable of collecting fine chips.

Background technique

With the gradual development of society, there are more and more solid waste products, and crushing is an important link in the solid waste recycling process. However, the current solid waste crushing link has the following defects: 1. There are many types of solid waste, and the volume Different, in the process of crushing or shearing, there will be a risk of jumping out from the upper part of the crushing or shearing equipment, which greatly threatens the work safety of the on-site personnel; 2. The solid waste is not completely crushed, and the volume of the crushed material is very different , which is not conducive to rapid and centralized collection and processing in the later stage. Generally, secondary crushing is required, which is not only low in efficiency, but also increases labor intensity; 3. Even after secondary crushing, the small particles after crushing are inconvenient to collect, and manual classification is required. The subsequent processing not only increases the labor intensity but also easily leads to the loss of solid waste; 4. Solid waste dust is easily generated during the crushing process, which not only affects the indoor environment, but also brings great damage to the physical and mental health of on-site workers.
