A crushing, screening and mixing machine

Abstract

The invention discloses a crushing, screening and stirring integrated machine, and belongs to the field of biomass processing equipment. The integrated machine includes a machine body shell, a transmission shaft, a crushing blade, a crushing layer bottom plate, a stirring paddle I, a screening layer bottom plate, a stirring paddle II, a stirring layer bottom plate, filter nets and controllable switches; the crushing layer bottom plate, the screening layer bottom plate and the stirring layer bottom plate are sequentially and fixedly connected with the inner wall of the machine body shell from the top to the bottom; one end of the transmission shaft is vertically fixed on the center of the bottom wall in the machine body shell through a bearing seat, and the end part of the other end is fixedly connected with the crushing blade; the transmission shaft sequentially passes through the stirring layer bottom plate, the screening layer bottom plate and the crushing layer bottom plate from thebottom to the top; and the stirring paddle I and the stirring paddle II are fixedly connected with the transmission shaft. The integrated machine provided by the invention can separate particles withdifferent sizes, so that the time consumed by production of two raw materials is saved and the energy is saved to a certain extent; and the integrated machine realizes reasonable utilization of spaceand saves the energy consumed by operation of a plurality of large-scale machinery.

Description

technical field [0001] The invention relates to a crushing, screening and mixing integrated machine, which belongs to the field of biomass processing equipment. Background technique [0002] According to relevant statistics, my country, as a large agricultural country, can produce more than 700 million tons of straw every year, only about 10%-15% of which is utilized. In this case, if it is completely handled by farmers, there will be a large number of incineration. Every year during the summer harvest and autumn and winter, a large amount of straw is always burned in the fields, resulting in a large amount of dense fog and causing the "greenhouse effect". [0003] Straw is mostly used for burning, which is a major source of environmental pollution. According to data, when straw is burned, the three pollution indexes of sulfur dioxide, nitrogen dioxide, and inhalable particulate matter in the atmosphere reach their peaks, and the concentration of sulfur dioxide is higher th...

Problems solved by technology

[0005] In order to solve the problem that there is no device for processing straws that integrates crushing, screening and stirring in the prior art, the present invention provides a crushing, screening and stirring integrated machine. This device integrates crushing, screening and stirring, and can simultaneously realize The crushing, screening and stirring of straw do not need to be carried out separately, which greatly saves the production cost. The technical scheme adopted is:
