Uniform material distribution device for rotary combined multi-layer screen

Abstract

The invention relates to a uniform material distribution device for a rotary combined multi-layer screen. The uniform material distribution device comprises a rack, a screen body hung on the rack, and a feeding shell at the upper end of the rack, wherein a feed inlet is formed in the feeding shell; an upper material uniformization plate and an upper material guide plate in the feeding shell form an upper feeding channel of which the section is funnel-shaped; a lower material guide plate and a lower baffle plate in the feeding shell form a lower feeding channel of which the section is funnel-shaped; an opening in the upper end of the upper feeding channel corresponds to the feed inlet; an opening in the lower end of the upper feeding channel corresponds to an opening in the upper end of the lower feeding channel; an opening in the lower end of the lower feeding channel corresponds to a feed hopper arranged on the screen body; the feed hopper communicates with a uniform material distributor arranged on the side surface of the screen body; a plurality of vertical discharge channels are arranged in the uniform material distributor; and the discharge channels communicate with different screen grids. According to the uniform material distribution device, uniform distribution of grain materials is achieved, the grain materials uniformly enter the different screen grids, the multiple layers of screen grids screen the grain materials at the same time, and screening efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of grain screening and impurity removal equipment, in particular to a uniform batching device for a rotary combined multi-layer sieve. Background technique [0002] Before the grains are put into the warehouse, because the grains contain impurities and dust, if the impurities are contained in the grains, it will cause the grains to heat up and become moldy, and it will also make the flow of the grains out of the warehouses difficult, resulting in serious losses of grains. Therefore, the grain must be cleaned before storage, and the impurities and some dust in the grain must be screened out. At present, there are many kinds of equipment for screening and dedusting grain on the market, such as vibrating screens, flat rotary screens, etc., but most of the existing screening and dedusting equipment have single functions and low screening efficiency, which cannot meet the screening needs of large grain depots.
