Negative pressure dust-removing system for grain dust

Abstract

The invention discloses a negative pressure dust-removing system for grain dust. The negative pressure dust-removing system comprises a grain cabin, wherein a bucket elevator is fixedly connected withan outlet on the lower surface of the grain cabin; a crushing device is fixedly connected with the outlet on the rear side of the upper surface of the bucket elevator; a vibration screen device is fixedly connected with the outlet of the crushing device through a conveying device; a buffering cabin is fixedly connected with the outlet of the vibration screen device through the conveying device; apackaging device is fixedly connected with the outlet of the buffering cabin through the conveying device; an exhaust pipe is fixedly connected with the upper surfaces of the crushing device, the vibration screen device, the buffering cabin and the packaging device; a connecting pipe is fixedly connected with the upper surface of the exhaust pipe; a cyclone dust removal device is fixedly connected with the outlet of the connecting pipe; and an explosion-proof valve is fixedly connected with the outlet of the cyclone dust removal device through the pipeline. The negative pressure dust-removingsystem for grain dust is capable of greatly promoting the use convenience and safety, promoting the dust collection effect and guaranteeing the working efficiency.

Description

technical field [0001] The invention relates to the technical field of dust removal systems, in particular to a grain dust negative pressure dust removal system. Background technique [0002] During the storage, transportation and processing of wheat, corn and other grains, due to environmental and human factors in the harvesting process, a large amount of dust will inevitably be generated, and in order to ensure the quality and safety of grain processing, it is necessary to remove dust from the grain processing, and the current processing method basically uses the method of immersion to remove the dust mixed in the grain, which not only wastes a lot of water resources, but also needs to dry the grain many times, which is not only inefficient, but also a waste of energy. The efficiency and safety of grain processing are greatly reduced, and dust removal can only be carried out during the grain storage stage. The effect is single, and the safety during processing cannot be gu...

[0002] During the storage, transportation and processing of wheat, corn and other grains, due to environmental and human factors in the harvesting process, a large amount of dust will inevitably be generated, and in order to ensure the quality and safety of grain processing, it is necessary to remove dust from the grain processing, and the current processing method basically uses the method of immersion to remove the dust mixed in the grain, which not only wastes a lot of water resources, but also needs to dry the grain many times, which is not only inefficient, but also a waste of energy. The efficiency and safety of grain processing are greatly reduced, and dust removal can only be carried out during the grain storage stage. The effect is single, and the safety during processing cannot be guaranteed, which will affect the quality of grain. If the dust concentration is not controlled, The safety of production and processing sites is not guaranteed, and explosion accidents are prone to occur
