Working principle Stirred material is unloaded into the vibrating hopper by the material mixer's discharge port (or artificial mixing and feeding), fed into the hopper of the spraying machine through the screen mesh, and pulled into the direct feed cavity of the rotor by the dial feeder. As the rotor rotates to the exit, it is blown into the cyclone by compressed air that is vented to the chamber. Here, another gas is introduced by the cyclone, and the material is blown, accelerated, rotated, floated, entered the feed pipe in a multi-end spiral manner, and reaches the sprinkler to add a small amount of make-up water.
Rotor Type Concrete Shotcrete Structure PZ series rotor type concrete shotcrete mainly consists of driving device, rotor assembly, air circuit system, injection system and electric control box.
1. The fully enclosed oil-immersed speed reducer of the drive device is installed on the bottom of the machine and is driven by a three-stage gear. The total transmission ratio is approximately 109, and the transmission efficiency is approximately 92%. The motor is mounted vertically on the gear unit parallel to the rotor shaft.
2. Rotor assembly PZ series rotor type concrete spraying machine adopts a unique straight-through anti-sticking material rotor. Each circular hole is lined with plastic material cavity made of non-bonding material, thus improving the sprayer's processing wetness. The material's ability to reduce the cleaning and maintenance workload.
Steel liner: There is a steel liner on the upper and lower sides of the rotor body. The liner has high hardness, wear resistance and service life of more than 4000m3 of concrete material.
Rubber plate: There are two blocks of upper and lower, made of special rubber, very wear-resistant, and the service life is 300-400 m3 of concrete material.
Pressing mechanism: The use of screw force, cylindrical rubber spring as elastic automatic pressing device. The machine is pressed at four points to ensure that the pressure distribution at the seal joint surface is reasonable. After the seal plate is worn out, the elastic deformation force of the rubber spring will cause it to automatically press against the rotor lining plate and maintain a considerable pressing force at all times, which improves the sealing effect and reduces the escape of dust; at the same time, it can also avoid the use of glue. The plate is pressed too tightly and excessively to wear, prolonging the life of wearing parts.
3. Three ball valves of the wind system are used to control the main wind path, the upper wind path leading to the rotor and the lower wind path leading to the cyclone. Another small air duct is used to supply air to the hopper vibrator. There is also a pressure gauge in the lower air path to monitor the working pressure of the feed pipe.
4, the injection system The system is composed of feeding hoses and nozzles. The conveyor pipe uses wear-resistant spray pipe. The nozzle is made of polymer injection. Water pipes, water rings, and water valves are fixed on the spray head.
5, the electrical control box electrical control box by the leakage of air automatic switch, AC contactor, fuse and start stop button, can achieve leakage, transition, short circuit and other protection functions.
