Biomass fiber wind separation equipment

Abstract

The invention belongs to the field of biomass fibers, and discloses biomass fiber wind separation equipment. The biomass fiber wind separation equipment comprises a wind separation box, a feeding hopper is arranged at the top of the wind separation box, a feeding pipe is arranged at the bottom of the feeding hopper, a pad of the feeding pipe penetrates through and extends into the wind separationbox, and the feeding pipe is fixedly connected with the wind separation box. According to the biomass fiber wind separation equipment, the biomass fibers are fed into the wind separation box through the feeding hopper and the feeding pipe, meanwhile, a wind separation fan is powered on to conduct wind separation on materials, fine fibers subjected to wind separation enter a collecting bag througha discharging port and a collecting hopper to be collected, the discharging amount can be effectively controlled by adjusting a material equalizing assembly, meanwhile, the materials are evenly distributed, so that the materials are lifted and dropped, the situation that excessive materials exist in local parts is avoided, and the wind separation efficiency is improved; and large coarse residues and small coarse residues obtained after wind separation are classified and screened through two filter screens and a supporting and limiting device, the separation effect is effectively improved, andthe utilization rate of the coarse residues is increased.

Description

Technical field [0001] The invention relates to the field of biomass fiber, and more specifically, to a biomass fiber winnowing device. Background technique [0002] Biomass fibers can be basically divided into three categories: biomass virgin fibers, biomass regenerated fibers, and biomass synthetic fibers. The biomass virgin fibers represented by cotton, wool, hemp, and silk are China’s traditional dominant varieties; bamboo pulp, The rapid development of biomass regenerated fibers such as hemp fiber, protein fiber, seaweed fiber, chitin fiber, and direct solvent cellulose fiber can basically meet the needs of China's economic development and textile industry development; PTT, PLA, PHA and other biomass synthesis Fiber has broken through key technologies, and the production capacity of some products is world-leading. [0003] Biomass fiber raw materials generally need to be air sorted before being put into production and use, and the unqualified coarse slag is separated from the...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the problems existing in the prior art, the object of the present invention is to provide a biomass fiber winnowing equipment, which has the advantages of controlling the feeding amount and classifying and screening the coarse slag, and solves the problem that the existing winnowing equipment lacks uniform material. The device cannot control the feeding amount of the feeding pipe, which makes the local excess of materials in the winnowing equipment, resulting in low winnowing quality, and the coarse slag from the winnowing is also directly collected together, which reduces the utilization of coarse slag rate problem
