Environment-friendly grain vibration cleaning screen

Abstract

The invention relates to an environment-friendly grain vibration cleaning screen which comprises a vibrating screen, wherein a feeding port is formed in the top of the vibrating screen; a dust collecting cover is arranged on one side of the feeding port; a dust collecting pipe is arranged at the top of the dust collecting cover; a fan is arranged at one end of the dust collecting pipe; an air exhaust pipe is arranged on one side of the fan; a dust removing box is arranged at one end of the air exhaust pipe; a water pump is arranged at the top of the dust removing box; and a water suction pipeis arranged on one side of the water pump. The environment-friendly grain vibration cleaning screen provided by the invention has the advantages of simple structure and convenient operation, can suckand discharge dust generated in a process of screening out grain impurities, avoids that the dust is mixed into grains to affect quality of the grains or rises up through the air to pollute the environment and damage health of staffs, can exhaust the dust-containing air by a watering purification fan, filters the dust, avoids direct discharge into the air to cause serious air pollution, recycles water after filtering the dust to save resources, and can collect screened stones and dust to avoid falling or flying to affect environmental sanitation.

Description

technical field [0001] The invention relates to an environment-friendly vibrating cleaning screen for grain, which belongs to the field of impurity removal devices for grain. Background technique [0002] Grain and grain will be mixed with many weeds, straw, stones, dust and other impurities during harvesting. Before grain processing and storage, these impurities need to be cleaned to improve grain cleanliness, improve grain quality, and facilitate grain storage. To avoid grain deterioration due to sundries, prolong the storage period of grains and grains, the existing grain removal devices usually use grain vibrating cleaning sieves, and use vibrating screens to sieve and clean grains. During the sieving and cleaning process, A large amount of dust is generated, and it is necessary to use the air separation and sedimentation mechanism to suck away the dust gas and then carry out sedimentation and dust removal treatment. It is difficult for the existing wind separation and s...

To avoid grain deterioration due to sundries, prolong the storage period of grains and grains, the existing grain removal devices usually use grain vibrating cleaning sieves, and use vibrating screens to sieve and clean grains. During the sieving and cleaning process, A large amount of dust is generated, and it is necessary to use the air separation and sedimentation mechanism to suck away the dust gas and then carry out sedimentation and dust removal treatment. It is difficult for the existing air separation and sedimentation mechanism to remove the dust. Generally, the gas treated by the wind separation and sedimentation mechanism is directly on the air. Empty air discharge, causing serious air pollution, poor working environment, and damaging the health of staff
