Double-layer isolating negative-pressure dust-proof system

Abstract

The invention provides a double-layer isolating negative-pressure dust-proof system. The double-layer isolating negative-pressure dust-proof system comprises an outer-layer sealing cover, an inner-layer sealing cover, a dust-collecting device, a dust-receiving device, a storage device and a dust conveying device, wherein the dust-collecting device is connected with the bottom of the inner-layer sealing cover and is used for collecting dust falling on the bottom surface of the inner-layer sealing cover; the dust-receiving device is connected with the top of the inner-layer sealing cover and isused for ventilating and filtering dust in dust-containing gas in the inner-layer sealing cover; the storage device is connected with the dust-collecting device and the dust-collecting device and is used for storing the dust filtered by the dust-collecting device and the dust-receiving device; the first end of the dust-conveying device is connected with the dust-collecting device and the dust-receiving device separately, and the second end of the dust-conveying device is connected with the storage device; and the dust-conveying device is used for conveying the dust collected by the dust-collecting device and the dust-receiving device to the storage device, so that high efficiency, environmental friendliness and energy conservation of dust prevention and dust removal are guaranteed, and internal cleanness of a workshop and cleanness of the discharged air are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of dust removal in processing workshops, and in particular relates to a double-layer isolation negative pressure dust prevention system. Background technique [0002] Crushing products are widely used in metallurgy, construction, coal, road construction, chemical industry and other industries, and play an important role in the industrial production process. A large amount of dust endangers the health of construction workers and residents, and damages the production of agriculture, forestry and animal husbandry. [0003] As people pay more and more attention to environmental protection requirements and their own health, and the government's stricter environmental protection requirements, the mine crushing industry also pays more and more attention to dust prevention and removal, hoping to achieve the effect of dust prevention and dust removal through effective means. [0004] At present, the mining industry ...

AI Technical Summary

Problems solved by technology

[0004] At present, the mining industry usually adopts methods such as setting ventilation and dust removal equipment at the inlet and outlet of the equipment or washing dust removal for the dust generated during the production process. Although this method can achieve the effect of dust removal, it cannot be fully sealed because the dust removal cover cannot be set. For various reasons, there will still be dust in the production workshop. After the dust falls to the ground, it needs to be cleaned frequently, causing internal pollution, and a waste of human resources, which seriously affects the health of workers.
