AI Technical Summary
Existing coal mine gas extraction devices do not have effective filtration devices when transporting mixed gas, which leads to the carrying of impurities and foreign objects, which may damage the equipment and cause blockages.
A coal mine gas extraction device was designed, which includes a filter component, a debris removal component, and a protective component. The device filters impurities through a filter plate, removes attached impurities through a vibrating motor, removes foreign objects through a debris removal component at regular intervals, and sprays water to extinguish fires when flames are detected.
It effectively removes impurities and foreign objects, prevents equipment blockage, ensures safe transportation and handling, prevents fires and explosions, and improves the reliability and safety of the equipment.
