Features of explosion-proof shotcrete machine:
1. Explosion-proof shotcrete machine is widely used in engineering construction, mines, tunnels, culverts, subways, hydropower projects, underground engineering and coal moor mine roadway sprayed concrete construction operations: various types of industrial furnaces, furnace linings, refractory materials, spray molding Soil transportation and spraying during mending and various slope protection and greening construction.
2. Structure of explosion-proof shotcrete machine: It is mainly composed of driving explosion-proof motor, quick-setting agent pump assembly, reducer, rubber elbow, rotor body assembly, mining rail wheel, sealed rubber plate, hopper seat, vibration hopper, It consists of snap ring, quick connection, shotcrete tube, nozzle holder, compaction mechanism, air path system and electronic control device.
3. Explosion-proof shotcrete machines are divided into underground dry-type shotcrete machines for coal mines and underground wet-type shotcrete machines for coal mines based on whether the added raw materials have water. According to the spraying capacity, they can be divided into 5 cubic (or 5) shotcrete machines 6 cubic and 7 cubic shotcrete machines.
4. Explosion-proof shotcrete machine adopts low-pressure and high-speed vortex airflow conveying. The mine shotcrete machine overcomes problems such as sticking, pipe blocking and pulse deflection during material conveyance. The material flow is uniform and continuous and stable. Among them, the new type nozzle and discharge elbow. The device can improve the spraying effect, less rebound, and high spray layer quality. The dust concentration near the machine and outside the nozzle is greatly reduced, and the harm to the worker's profile is eliminated. Reduce the incidence of occupational diseases, low rebound, dry spray: the rebound rate of concrete can reach 25% -50%, and the rebound rate of wet spray technology can be reduced to less than 5%.
