Biomass particle screening and recycling device

Abstract

The invention provides a biomass particle screening and recycling device, and belongs to the technical field of biomass particles. The biomass particle screening and recycling device is used for solving the problem that the crushing efficiency of the recycled biomass particles is low. The biomass particle screening and recycling device comprises a sliding mechanism and a rolling mechanism, wherein the sliding mechanism comprises a U-shaped sliding plate; a screening mechanism is arranged below the U-shaped sliding plate; the rolling mechanism comprises a chain wheel pair and a sliding groove plate; the sliding groove plate is fixed below the U-shaped sliding plate; a mounting cylinder is fixed below the sliding groove plate; a quantitative rotating disc is rotationally arranged in a discharging hole; a rolling box is fixed below the mounting cylinder; a driving roller and a driven roller are rotationally arranged in the rolling box; the driving roller and a rotating shaft are connected through the chain wheel pair; a rolling motor is fixed on the side surface of the rolling box; an output shaft of the rolling motor is connected with the other end of the driving roller; and an impact mechanism is arranged below the rolling box. According to the biomass particle screening and recycling device, the rolling mechanism and the impact mechanism are matched, so that the recycled biomass particles can be rolled and pulverized at one time, and the crushing efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of biomass particles, and relates to a device for screening and recovering biomass particles. Background technique [0002] Biomass pellets are processed by cold-state compacting of pulverized biomass straw, forestry waste and other raw materials by using pressing rollers and ring dies at room temperature, which is convenient for storage and transportation, and greatly improves the combustion performance of biomass . my country is a big energy-consuming country, so adjusting the energy structure and using biomass energy is an inevitable choice. After the biomass is compressed and molded, its volume is greatly reduced, which makes it easier to transport, store and use, and solves the key problem of large-scale utilization of biomass. Therefore, this technology and equipment are very suitable for clean energy transformation of biomass power generation and industrial boilers , New rural cooking fuel. [0003...

AI Technical Summary

Problems solved by technology

[0003] Unqualified products in the existing biomass particles are often crushed and reduced to raw materials for secondary use. However, biomass particles are compacted in a cold state, resulting in small unit volume and high density of biomass particles. There is a pulverization device that cannot completely pulverize it, and there are large particle debris in the pulverized biomass particles, which requires multiple pulverization processes, which reduces the recovery efficiency of biomass particles
