The structure and characteristics of star-shaped ash discharge valve YJD-A

The structure of the star-shaped dust discharge valve is composed of a rotor impeller with several blades, a shell, a seal, a reducer, and an electric motor.
1. The upper and lower flange ports of the star-shaped ash discharge valve are basically square or circular, and can also be selected by the user.
2. When the material in the upper bin falls by its own weight and is filled in the gap between the blades, it is discharged at the lower part with the rotation of the blades. Therefore, the star-shaped ash discharge valve can discharge quantitatively and continuously.
3. Wear-resistant closed rotor impeller This type of star-shaped ash discharge valve is characterized by the end of the rotor blades being lined with polyfluoroethylene sealing strips, which ensures good contact between the blade ends and the inner wall of the shell, and can be used after wear. Conveniently adjust the blade end so that it still maintains good contact with the inside of the housing and has better air-locking performance.
4. Star-shaped ash unloading valves are commonly used in pneumatic output systems. For pressure output systems or negative pressure output systems, star-shaped ash unloading valves can evenly and continuously supply material to the feeding pipe to ensure that the pneumatic output pipe The gas and solids are relatively stable, so that the pneumatic conveying can work normally. At the same time, it can isolate the air pressure at the upper and lower parts of the ash unloading valve and play the role of air locking. Therefore, the star unloading valve is an important component commonly used in pneumatic conveying systems.
5. Temperature-resistant type The temperature of the materials transported can reach a certain distance between the bearings at both ends and the impeller, which can prevent ultra-fine powder from contacting the bearings. The high-temperature-resistant ash discharge valve can transport materials up to a temperature that is connected by a sprocket. There is a certain distance between the reducer and the ash discharge valve housing.
6. The star-shaped ash discharge valve can be used in the material collection system as the ash discharge valve of the silo. The star-shaped dust unloading valve is currently the most advanced unloading device in the country. It is commonly used in dust removal systems as one of the important equipment of the dust removal system. It is especially suitable for dust and small particle materials. It is popular among environmental protection, metallurgy, chemical industry, food, cement , road construction, drying equipment and other industrial projects are selected for use
Features of star-type dust discharge valve:
By using the principle of planetary rotation, the input and output are on the same axis, and there is a direct connection with the motor. Unique, compact structure, beautiful and novel shape, small size and light weight.
Reliable and stable operation, low noise, few faults, long life, and the gearing parts are made of ductile iron and bearing steel. Good performance and high wear resistance.
The bearings and gearbox are kept away from the valve body to avoid the influence of high-temperature dust. The front and rear end covers have good sealing performance to prevent dust from leaking and extend the service life of the moving parts and lubrication system.
This machine has strong overload capacity, small impact resistance and small moment of inertia, and is suitable for frequent starts and reverse and forward rotation.
