Full-automatic crop straw powder preparation system

Abstract

The invention discloses a full-automatic crop straw powder preparation system. The full-automatic crop straw powder preparation system consists of a cutting dust remover, a cutting machine, a storage silo, a cutting mill, a powder concentrator, a cyclone collector with an unloader, a circulating fan with a recirculating air valve, a dust remover with a dust remover fan valve and a dust removal fan which are connected in sequence. Full-automatic operation of cutting straws, crushing, grading, collecting, dedusting and the like are realized, plant straws are placed in an inlet of the cutting machine, straw powder which meets the requirement can be obtained at an outlet of cyclone collecting equipment, the dedusting function is realized by system dedusting equipment, and the thermal pollution problem caused to an environment in the powder preparation process is solved.

Description

technical field [0001] The invention relates to a crushing and grading machine, in particular to a crop straw crushing device. Background technique [0002] In the preparation process of crop straw powder, due to the small specific gravity and large volume of crop straw powder, it brings great difficulties to grinding and grading. Rotational speed is the key factor restricting the preparation of crop straw powder. Therefore, the society urgently needs a new type of crop straw powder preparation system, which can cut the crop straw into a length of 1-2cm through the cutting equipment in the system, and crush it with the crushing equipment. Under the negative pressure of the crop straw powder preparation system, the qualified particles crushed by the mill are sorted by the powder classifier according to the requirements, so as to ensure that the diameter of the crop straw powder particles is controlled within the required range, and the cyclone collects the sorted qualified p...

AI Technical Summary

Problems solved by technology

[0003] The invention is mainly aimed at the fully automatic preparation process of cutting, crushing, grading, collecting, dust removal and control in the preparation process of crop straw powder, and solves the difficulty brought by the small specific gravity and large volume of crop straw powder to grinding and grading. Through research and development The designed key structures such as circulating fans and control valves in the automatic preparation system of crop straw powder can change the material-steam ratio, feeding concentration and system air volume in the process of grinding and grading, and adjust the frequency of circulating fans in the system and control the opening of valves. And the speed of the powder selector, realize the automatic process of crop straw powder preparation, meet the requirements of ensuring product accuracy on the basis of high output and low energy consumption, realize the improvement of output and accuracy, and achieve the purpose of reducing energy consumption
