Shotcrete concrete pump for sale is an equipment used for dry spraying and wet spraying concrete. It has the characteristics of advanced technology, reasonable structure, stable performance, convenient operation and maintenance, and long service life. Whether it is field spray slope protection or building wall reinforcement, it can meet your needs. The dry shotcrete machine does not require very high media, as long as the diameter is below 20mm, it can be sprayed. Shotcrete is the use of compressed air to transport a certain proportion of concrete mixture through a pipeline and spray it at a high speed to the sprayed surface to set and harden, thereby forming a concrete supporting layer.
Shotcrete technology is widely used in tunnels, culverts, subways, hydropower projects, underground works and shotcrete construction operations in coal mines, swamp mines, and tunnels due to its simple process, unique effects, economical cost and fast construction speed.
The mixed material is fed into the hopper of the ejector from the discharge port of the batching mixer through the vibrating screen, and is injected into the straight-through material cavity of the rotor by the dialer, and swirls with the rotor to the discharge port, where it flows from the air chamber. The compressed air is introduced, the material is blown into the discharge elbow, and another pressure air is introduced by the cyclone, which blows and accelerates the material in a multi-headed wind spiral state, and makes it rotate and float, enter the conveying pipe, and reach the nozzle. Add a small amount of supplementary water (when wet spray) and spray out.
1. Shotcrete pump for sale is mainly composed of driving device, rotor assembly, air duct system, spraying system, electrical control box (no control box when using explosion-proof motor) and other parts.
2. The fully enclosed oil-immersed reducer of the drive device is installed at the bottom of the machine and is driven by three-stage gears. The total transmission ratio is about 87, and the transmission efficiency is 92%. The motor is installed vertically on the reducer, parallel to the rotor shaft.
3. Rotor assembly The machine adopts a unique straight-through anti-stick rotor, with a rotating capacity of 10L and 10 material cavities. The lining of each material cavity is made of non-bonding material, which improves the machine's ability to handle wet materials. capacity, reducing the workload of cleaning and maintenance.
4. The three spherical valves of the air passage system are used to control the main air passage, the upper air passage leading to the rotor and the lower air passage of the ventilation cyclone. Another small air duct is used to supply air to the hopper vibrator, and there is also a pressure gauge in the lower air path to monitor the working pressure of the conveying pipe.
5. Spray system is composed of a feeding hose and a spray head. The spray head is made of polymer material by die casting, and the water pipe, water ring and water valve are fixed on the spray head.
6. Electrical control box (no control box when using explosion-proof motor) the control box is composed of leakage air automatic switch, AC contactor, fuse and start-stop button, which can realize protection functions such as leakage, overcurrent and short circuit.
