Anti-explosion dust removal device for grain production and processing

Abstract

The invention provides an anti-explosion dust removal device for grain production and processing, and belongs to the technical field of grain processing. The anti-explosion dust removal device comprises a box body, a dust collection box is fixedly arranged on the upper portion of the box body, and a feeding port is formed in the upper portion of the box body. A screening assembly used for filtering grain and a dust collection assembly used for collecting grain dust into the dust collection box are arranged in the box body. The screening assembly comprises an annularly-distributed separation net and two bases hinged to the bottom of the separation net. The two bases can rotate along the bottom of the separation net, and the two bases and the separation net form a conical structure with an upward opening. The anti-explosion dust removal device has the advantages of being simple in structure, convenient to use and good in dust collection effect, dust generated in the grain screening process is absorbed through the dust collection assembly, the situation that the dust concentration is increased due to the fact that too much dust is gathered in the box body is avoided, the potential threat of dust explosion is eliminated, and the safety in the grain processing process is improved.

Description

technical field [0001] The invention belongs to the technical field of grain processing, in particular to an explosion-proof dust removal device for grain production and processing. Background technique [0002] Food refers to the food that provides life energy for human beings and is needed for the survival of life, such as various plant seeds, fruits and vegetables, and meat products. Mainly protein, vitamins, dietary fiber, fat and so on. In ancient times, walking on the road was called food, and stopping living was called food. It is also commonly referred to as raw grains and finished grains such as cereals, beans, and potatoes for consumption. The food concept of the Food and Agriculture Organization of the United Nations (hereinafter referred to as the FAO) refers to grains, including wheat, beans, coarse grains and rice.

AI Technical Summary

Problems solved by technology

[0003] At present, most of the grains need to be screened out in the grain processing process to improve the quality of the grain. In the prior art, most of the grain screening is achieved by a screening machine. However, the existing screening machine When sieving grain, it is easy to cause grain dust to scatter. The dust is dispersed inside the sieving machine and with the increase of dust concentration, there is a threat of explosion. Therefore, the existing grain sieving machine is not safe.
