Blowing and sifting device for cereals and miscellaneous grains

Abstract

The invention discloses a device for blowing and sifting cereal grains, which comprises a frame. The inner bottom of the frame is provided with a storage pool, the top of the storage pool is an open structure, and the inside of the storage pool is provided with a separation bin. There is a primary screening chamber, the frame is installed on the base, and a stepping motor is installed inside the base. In the inner bottom, the upper end of the rotary drum is installed at the bottom of the primary screening bin; the lower end of the rotating shaft is fitted with a coiled tube, and the outer peripheral surface of the coiled tube is fitted with a stirring blade, which is installed inside the storage tank; the primary screening bin and the separation bin There is a blowing and sieving cavity in between; an air inlet pipe is installed inside the primary screening chamber, a blowing chamber is arranged at the lower end of the air inlet pipe, and a blowing pump is arranged at the upper end of the air inlet pipe. The present invention carries out two-stage blowing and sifting of cereals and miscellaneous grains, which greatly improves the efficiency of blowing and sieving of cereals and miscellaneous grains, and greatly improves the efficiency of blowing and removing inferior materials.

Description

technical field [0001] The invention relates to a blowing and sifting device for cereals and miscellaneous grains, in particular to a blowing and sieving device for cereals and miscellaneous grains. Background technique [0002] The four functions of the screen: sieve, filter, protect and solidify. Sieve: Mainly used in metallurgy, coal, rubber, petroleum, chemical, pharmaceutical, automobile, ceramics, glass and other industries as solid particles, powder, sieving, etc. Filtration: It is mainly used as mud net in petroleum industry, pickling net and liquid gas filtration and purification in chemical fiber electroplating industry. Protection: Mainly used for civil construction batch cement, raising chickens, ducks, geese, rabbits and zoo enclosures. Protection of machinery and equipment, highway guardrails, fences for sports venues, and protective nets for road green belts. Solid: It can be used in the construction industry, highways, and bridges as steel bars and skeleto...

AI Technical Summary

Problems solved by technology

The existing sieve is inconvenient to blow and sieve cereals and miscellaneous grains, and does not have a horizontal rotating blowing mechanism, so the blowing effect is poor, and the efficiency of blowing and sifting cereals and miscellaneous grains is low
