Mine Touch Automatic Sprinkling And Dust Reducing Device
Mine touch sensors are intrinsically safe for mining and are suitable for use in coal mines where there is a danger of gas or coal dust explosion. It is suitable for working places such as rail transportation lanes, belt lanes, coal slip eyes, etc. The system is mainly composed of touch sensors, controllers, Solenoid Valves, nozzles, water pipes, etc. When someone or something touches the touch sensor, or when the belt conveyor is running, the touch sensor generates a trigger control signal, which is transmitted to the controller through the transmission cable. The belt is sprinkled to remove the dust generated when the locomotive and belt are running. When the locomotive passes or the flow stops, the watering stops.
■ Performance characteristics
1. The touch sensor consists of three parts: coal level, coal transportation and humidity.
2. Coal level: When there is coal on the conveyor belt, the position of the lever of the touch sensor is deflected, and the coal light on the coal level is on, indicating that coal has been detected on the conveyor belt.
3. Coal transportation: When the conveyor belt is running, it drives its rollers to rotate, so that the coal transportation can detect the magnetic field change of the magnetic steel sticking to the rollers, and the coal transportation indicator lights up, indicating that the conveyor belt is in the coal transportation state.
4. Coal humidity: When there is coal on the conveyor belt, the two probes are in contact with the coal, and different resistance values are detected according to the humidity, thereby detecting the humidity of the coal. When the humidity of the coal meets the dry coal standard, the dry coal indicator of the sensor lights up, indicating that the coal is detected as dry coal.
5. Only when the three sensors meet the conditions at the same time, the sensor outputs a high level (voltage> 0.5V), otherwise it outputs a low level (voltage <0.5V).
