The automatic sprinkler dust-reducing device for mine is mainly used for automatic sprinkling of fire, dust and dust in the flammable parts such as belt, nose and tail of coal mine belt transportation lane.
The mine automatic sprinkler dust-reducing device is equipped with a touch sensor, a smoke sensor, a temperature sensor, and sprays a special part to achieve the purpose of extinguishing dust.
The mine automatic sprinkler dust-reducing device is composed of a main machine, an electric ball valve, a touch sensor, a smoke sensor, a temperature sensor and the like.
A variety of signal acquisition can effectively achieve dustproof, fireproof and fireproofing of the head, and prevent overheating of the gearbox and bearings. The main engine can drive two electric ball valves; one for the belt reloading point dust spray, one for the temperature sensor, the smoke sensor, and the fire extinguishing spray.
Working principle of mine automatic sprinkler dust-reducing device: When the belt sensor rotates, the touch sensor detects that the belt has material, the signal is transmitted to the host to reduce dust, the electric ball valve is instantly opened, and the head and belt are dust-proof. When there is no material, the delay is certain. Automatically close after time. When one of the ambient temperature or the smoke concentration exceeds the set value, a signal is transmitted to the host, and the dust-proof and fire-proof two-way electric ball valves are automatically opened. All the way to the belt main engine drive wheel and friction belt are sprayed to eliminate smoke and reduce dust and temperature. All the way to the conveyor belt to spray dust and cool down. When the temperature and smoke monitoring values ​​are lower than the set value, the electric ball valve automatically closes after a certain time delay.
