　　PS5I wet spraying machine for coal minesIntroduction:

　　Wet shotcrete refers to mixing cement, coarse and fine aggregates, and water together in a certain mix ratio, and then using various types of wet shotcrete machines to transport the mixed concrete to the nozzle through a feeding hose. Liquid accelerators are added at the nozzle, and compressed air is used to supplement energy, forming a bundle of concrete that is sprayed onto the surrounding rock surface from the nozzle.

　　PS5I wet spraying machine for coal minesConstruction technology is widely used in the field of tunnel construction. Dry spraying and wet spraying are commonly used in shotcrete construction in China. With the continuous development of construction technology, a new shotcrete construction technology - wet shotcrete is gradually being applied in shotcrete construction operations. PS5I wet shotcrete machine is a new type of concrete spraying machinery, mainly used for wet spraying of wet concrete. Wet spraying can make the mixture evenly mixed, accurately control the water cement ratio, and facilitate the hydration of water and cement. Therefore, it has low dust, low rebound, good concrete homogeneity, and high strength. The machine has the characteristics of reasonable structure, stable performance, convenient operation and maintenance, and long service life. Widely used in mining, tunnels, culverts, subways, hydropower engineering, underground engineering, and coal mine roadway shotcrete construction operations.

　　PS5I wet spraying machine for coal minesMain structure:

　　The wet concrete spraying machine mainly consists of four parts: mechanical power system, feeding system, air supply system, and rapid setting agent addition system.

　　1. Air supply system: This system mainly consists of a main inlet duct, a branch duct, a pressure gauge, an upper air duct, a lower air duct, an air duct, valves, and pipelines.

　　2. Rapid setting agent addition system: mainly composed of metering pump, joint pipeline, etc.

　　3. Mechanical power system: mainly uses the mechanical power generated by the driving motor to reduce speed and increase torque through the gearbox, and then drives the rotor body to rotate through the output shaft.

　　4. Feeding system: mainly composed of hopper, vibrator, rotor body, etc.

　　PS5I wet spraying machine for coal minesWorking Principle:

　　1. Concrete is mixed by a mixer according to the ratio and added to a vibrating hopper. It falls into the material chamber of the rotor body through a sieve, and the rotating rotor body brings the material in the chamber to the discharge port of the panel. Compressed air enters the "air distributor" of this machine and is divided into three paths: one path to the rapid setting agent mixer, one path to the cyclone (downstream air path), and one path to the hopper seat (upstream air path). The air in this path passes through the hopper seat, the material chamber of the rotor body, and directly leads to the discharge port of the panel. So, when the material chamber of the rotor body containing the material reaches the discharge port, compressed air blows the mixed material through the cyclone and sandblasting pipe to the nozzle. The air in the downwind path passes through the cyclone and forms a cyclone. Therefore, when the material flow passes through the cyclone, its material is accelerated and rotated, making it less likely to cause adhesion and blockage of the pipe.

　　2. Rapid setting agent addition system

　　The addition of liquid accelerator is accomplished by a conveying system, which is powered by an accelerator pump. Composed of components such as a storage tank, integrated block, and flow meter. The integrated block includes an overflow valve, a one-way valve, and a mixing chamber. The liquid accelerator is pumped out from the storage tank by the accelerator pump, and then flows through the overflow valve, regulating valve, and flow meter to the mixing chamber. The pressure air from the air separator blows the accelerator to the nozzle seat and mixes it with the mixed material before spraying it out.
