Star-A unloader

Product Introduction
1. Star unloading device is also called star unloading valve, star unloader, rotary feeder, air lock valve. Usually the star unloading structure is composed of several blades. It consists of rotor impeller, shell, seal, reducer, motor, etc.
2. When the material in the upper bin falls by its own weight and fills the gap between the blades, it is discharged at the lower part with the rotation of the blades. Therefore, the star unloader can discharge quantitatively and continuously.
3. Star unloaders are commonly used in pneumatic output systems. For pressure output systems or negative pressure output systems, star unloaders can evenly and continuously supply materials to the feeding pipe to ensure that the contents of the pneumatic output pipe are The air and solids are relatively stable, so that the pneumatic conveying can work normally. At the same time, it can also isolate the air pressure at the upper and lower parts of the unloader to lock the air. Therefore, the star unloader is a commonly used and important component in pneumatic conveying systems.
4. The star unloader can be used in the material collection system as the unloader of the silo. The star unloader 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 well received by environmental protection, metallurgy, chemical industry, food, cement , road construction, drying equipment and other industrial industry engineering projects are selected and used.
5. The upper and lower flange ports of the star unloader are basically square or circular, and can also be selected by the user.
6. Wear-resistant closed rotor impeller This type of star-shaped unloader 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.
7. 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 temperature of the high-temperature-resistant conveyed material can reach up to 100 degrees. It is connected by a sprocket, and there is a certain distance between the reducer and the unloader housing.
