Embodiment Construction

[0010] One embodiment of the present invention is as shown in the accompanying drawings of the description. The system consists of a cutting dust collector 12 connected in sequence, a cutting machine 11, a storage bin 10, a cutting mill 9, a powder separator 8, and a cyclone with an unloader 1. The collector 7, the circulation fan 6 with the circulation air valve 5, the dust collector 4 with the dust collector fan valve 3 and the dust removal fan 2 are composed, and the automatic preparation process of plant fiber powder is realized in this system. During the implementation of the system, the cutting machine 11 realizes the cutting of crop straws, the mill 9 realizes the crushing of plant fiber straws, the powder separator 8 realizes the sorting of plant fiber powders, the cyclone collector 7 realizes the collection of plant fiber powders, and the circulation fan 6 is used for Control the circulating air volume of the system, and blow the ground plant fiber powder from the bott...

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...
