How it works It is mainly used for automatic spraying of coal dust generated by coal mine upper, underground belt transportation and coal trough, coal bunker, coal yard and coal transportation transfer point, which plays a role in purifying the air and environment. ◆ Product features When the belt conveyor conveys coal, the coal flow touches the chain of the sensor, and the touch sensor (or thermoluminescence control sensor) receives the signal to trigger the main engine to drive the main board, open the electric ball valve, and the device automatically reduces the dust of the wine, and automatically stops the wine spraying when there is no material. The host can be sprayed at regular intervals through the remote control, and multiple time periods can be set to save water resources and reduce the burden of underground drainage. The host uses wireless signals for data transmission between the host and the sensor, and the host analyzes the received external data and controls it logically, so as to realize the wireless wine dust reduction function. ◆ Technical parameters Operating voltage: 12.8VDC Operating current: ≤0.3A Ambient temperature: 0°C°C~40°CC Enclosure rating: IP65 Explosion-proof mark: ExiblMb Explosion-proof certificate: CCCMT22.0425 Safety sign number: MDC220079 Warning: It is strictly forbidden to charge and disassemble the battery underground Intrinsically safe parameters: battery: Uo: 4.5V, Io: 3A
