Overview

The star-shaped ash discharge valve is also called the star-shaped unloader, electric air lock valve, star-shaped unloader, rotary feeder, air lock valve. Generally, the structure of the star-shaped unloader is a rotor impeller with several blades. , Housing, seals and reducers, motors, etc.

When the material in the upper silo falls by its own weight and fills the gap between the blades, it is discharged in the lower part with the rotation of the blades. Therefore, the star-shaped unloader can unload quantitatively and continuously.

The star discharger is commonly used in pneumatic output systems. For pressure output systems or negative pressure output systems, the star discharger can evenly and continuously feed the conveying pipe to ensure that the gas and solids in the pneumatic output pipe are relatively stable. So that the unloader conveying can work normally, at the same time, the upper and lower air pressure of the unloader can be cut off to play the role of air lock. Therefore, the star discharger is an important component commonly used in pneumatic conveying systems.

The star discharger can be used in the material collection system as the discharger of the silo. Commonly used in dust removal systems as one of the important equipment of dust removal systems, it is especially suitable for dust, small particle materials, and is widely used in environmental protection, metallurgy, chemical, food, cement, road construction, drying equipment and other industrial projects.

The upper and lower flange openings of the star-shaped unloader are basically square or round, and can also be selected by the user.

Wear-resistant closed rotor impeller The star-type unloader is characterized in that the ends of the rotor blades are lined with a polyvinyl fluoride sealing strip, which can ensure that the blade ends have good contact with the inner wall of the shell, and the blade ends can be easily adjusted after wear So that it still keeps good contact with the inside of the casing, and has better air-locking performance.

The temperature of the temperature-resistant star discharger can reach 280 ℃. The bearings at both ends are separated from the impeller to prevent the ultra-fine powder from contacting the bearings. The high-temperature-resistant discharger can convey boring temperatures up to 500 ° C. It is connected by sprocket, and there is a certain distance between the reducer and the unloader casing.
