Abstract

The invention discloses a micro-crushing device suitable for biomass straws, belongs to the field of crushing machinery. and solves problems that an existing crushing device has low production efficiency and the smashing granularity does not reach the standard in a straw type material micro-crushing process. A technical scheme is as follows: a coarse straw material enters a crushing area through a feeding port, a high-speed rotating cutting blade disk and a static cutting disk move relatively, when the material passes through a cutting blade disk area, the material is crushed through cutting, impact and crushing of the high-speed rotating cutting blade disk and a cutting disk and is scattered, the material enters matching positions of movable cutters and fixed cutters under the action of an impact force, the material is impacted, cut and crushed by the cutters, and is impacted on convex teeth of the blade disks to be subjected to an action of a friction force, and an expected crushing effect is achieved under the action of the multi-layer cutters and the convex teeth. A detachable design facilitatesmaintenance of thecutters, under a combined action of multiple crushing modes, the material crushing effect is good, and the micro-crushing device suitable for biomass straw is of great significance in development and utilization of biomass straw.

Description

technical field [0001] The invention relates to a fine pulverization device, in particular to a fine pulverization device suitable for biomass stalks, and belongs to the field of pulverization machinery. Background technique [0002] my country is a large agricultural country, and with the harvest of agricultural products, a large amount of crop straw is produced every year. Due to the low price and abundance of straw resources, most of the crop straws are burned on the spot or directly discarded. Incomplete combustion of straws will produce smoke and toxic gases, causing great damage to the environment, and irregular burning may also cause forest fires. In recent years, the country has actively promoted the reuse of waste resources. As a renewable and clean energy source, crop straw has great development and utilization value. Straw powder can be used as raw materials for wood-plastic composite materials, leather, building decoration materials and other products. The utili...
