Abstract

The invention discloses an automatic dedusting system for coal mines, which comprises a nozzle, a dedusting medium supply system, an air compressing device, an explosion-proof coal dust concentration sensor, an explosion-proof electromagnetic control valve and an explosion-proof PLC control system, wherein the explosion-proof coal dust concentration sensor fixedly connected with the nozzle senses the coal dust concentration on the nozzle; the explosion-proof PLC control system analyzes a coal dust concentration signal transmitted by the explosion-proof coal dust concentration sensor and sends a dedusting medium ejecting instruction; and the dedusting medium ejecting instruction is performed by the explosion-proof electromagnetic control valve. The automatic dedusting system for coal mines can realize automatic control on dedusting operation, realize the matching of the ejection quantity of the dedusting medium and the coal dust concentration in real time, improve the dedusting efficiency, reduce medium consumption, save cost and energy source, simplify operation process and reduce labor intensity of workers.

Description

Technical field [0001] The invention relates to a dust removal device, in particular to an automatic coal mine dust removal system. Background technique [0002] In the process of coal mining, a large amount of dust is generated in the mining surface, transfer point, conveyor belt, ore crushing, screening and other processes in the tunnel. The dust not only pollutes the environment, but also seriously harms the health of the workers. Become a high-risk group susceptible to pneumoconiosis. The existing technology of dust prevention and control mainly includes three methods: high pressure spray, coal seam water injection and foam dust removal. The treatment process is generally completed by manual operation. The working area is large, the labor intensity is high, and the operation is cumbersome. At the same time, the concentration of coal dust at each dust occurrence point It is not easy to grasp, which makes it difficult to adjust the release amount of the dust removal medium. No...
