Along with the rapid development of the industry in China, the environmental pollution is more and more serious, and particularly in recent years, the environmental protection and ecological harmony become important issues concerned by all aspects of society.
In the field of coal mine production, a concrete injection support process is one of important pollution sources causing environmental pollution. The concrete spraying and supporting process gradually develops into two process methods of wet spraying and wet spraying after decades of development. The wet spraying process is basically free of dust emission, has little influence on environmental pollution and human bodies, is complex, needs large-scale transportation and stirring equipment, has short transportation distance requirement, is complex to maintain and clean after being used, is mainly suitable for large-scale ground engineering such as high-speed rails, construction sites, expressways, mountain-crossing tunnels, bridges and the like, and is mainly used in rock roadway support of subways and mine roadways due to narrow operation space.
At present, most of concrete wet spraying equipment adopts a rotor type concrete sprayer. The working principle of the device is that cement, melon seed pieces and yellow sand are uniformly stirred according to a specific proportion, the materials are stirred in batch in a blanking hopper through a stirrer and are fed into material cavities uniformly distributed in the circumferential direction of a rotor body, the materials are uniformly blown into a conveying pipeline to a spray gun through high-pressure air, and a water ring in the mixing spray gun is pushed to a sprayed working surface at a high speed.
