Introduction to a Series of Concrete Shotcrete Machines
A series of concrete shotcrete machines use compressed air to continuously transport concrete along pipelines and spray it onto the construction surface. It is divided into two types: dry spray machine and wet spray machine. The former transports dry mixture by pneumatic force, mixes it with pressurized water at the nozzle and then sprays it out. The latter uses pneumatic force or a concrete pump to transport the concrete mixture and spray it through the nozzle. It is widely used in the lining construction of underground engineering shafts, tunnels, culverts, etc.
The working principle of the second series of concrete shotcrete machines
The structure and working principle of the series of concrete shotcrete machines: The mixed materials are discharged from the mixer discharge port (or manual mixing and loading) It is fed into the hopper of the jet machine through the vibrating screen. The material is injected into the straight material cavity of the rotor by the dialer and then swirls to the discharge port. Here, compressed air is introduced from the air chamber to blow the material into the discharge port. At the elbow, another wind pressure is introduced by the cyclone, which blows and accelerates the material in a multi-head wind spiral state, and makes it rotate and float, enter the feeding pipe, and then add a small amount of supplementary water when it reaches the nozzle (during tide spraying) Or spray liquid accelerating agent (when spraying wet).
The series of concrete shotcrete machines is mainly composed of the driving device, rotor assembly, air duct system, injection system, electrical control box and other parts.
Three series
Characteristics of concrete shotcutter
Straight-through rotor type non-bonded material cavity, smooth discharge, efficient and time-saving
Two- and four-point elastic compensation compression, sealing effect Good, less dust around the machine, long life of wearing parts
3. Use low-pressure and high-speed vortex air flow for transportation to overcome problems such as sticking, pipe blocking and pulse separation during material transportation. The material flow is uniform, continuous and stable.
