Dust disasters are a prominent issue in safety production in dusty workplaces, and are also a major hidden danger affecting the safety production of coal mines. The automatic spray control device can reduce dust and purify the air through continuous automatic spraying, while also It can absorb certain harmful gases, reduce gas concentration, improve and control the dust working environment, and is a conventional equipment and important facility that can effectively prevent dust hazards. Currently, domestic automatic spray devices have shortcomings such as sensors that are prone to malfunction and solenoid valves that are easily damaged. In order to overcome Due to the above defects, our company has developed and produced an automatic water sprinkling and dust suppression device for mines. The device has great innovations in the circuit system. The main control box adopts an imported industrial-grade intelligent programming controller, which has superior performance, reliable quality, powerful functions, and a real-time clock. Function, it can be timed and run according to the schedule you need, and the time control is accurate to the second. It has an integrated circuit integrated sensor. Sensors of various principles can be configured according to user requirements. The high-reliability electric ball valve takes multiple measures to ensure spraying. The device can work continuously for a long time without failure.
Device composition
The device mainly consists of an explosion-proof and intrinsically safe mining automatic sprinkler dust suppression device main control box/mining intrinsically safe electric ball valve station R mining intrinsically safe pyroelectric infrared sensor unit Composition of dust concentration sensor. It is suitable for dusty operations and gas environments such as various coal mining underground coal mines, fully mechanized excavation belt tunnels, main belt transport lanes, various transfer points, etc.

Allowing eligible migrant children to take the college entrance examination on the spot is undoubtedly important in promoting educational equity. The floating population, represented by migrant workers in cities, has made a contribution that cannot be ignored for urban development. They and their children deserve treatment commensurate with their efforts. Otherwise, not only would it be unfair, but it would also not allow them to participate in urban construction with peace of mind.
