Cast Iron Motor Reducer Drive Impeller Feeder Rotary Airlock Valve

I. Overview.

Star-shaped ash unloading valve is also called electric air lock valve, star-shaped unloader, rotary feeder, air-locking valve, usually the structure of star-shaped unloading device is composed of a rotor impeller with several blades, a shell, and a seal And reducer, motor and other components. When the material in the upper silo 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-shaped unloader can discharge quantitatively and continuously.

Characteristics are below:

The star-shaped ash unloading valve has a compact structure and is easy to use; it runs smoothly and has low noise; because the bearing and gear box are away from the shell for a certain distance, it is relatively high-temperature and lubricating. It has the characteristics of beautiful appearance, compact and reasonable structure, use, light weight, large capacity, low power consumption, etc.

II. Working principle and structural characteristics

Star Unloader is composed of shell, impeller and end cover. The reducer, transmission shaft and impeller are combined into one, which is reliable, light and energy-saving. As the bearings and reducer of this machine are protruding outward, it can avoid the phenomenon of dust squeezing into the bearings and large granular material jamming.

III. Instructions for use

1. Check whether the motor wiring is correct and reliable before use, and whether to install overload protection.

2. This product has been added No. 00 lithium grease before leaving the factory.

3. This product is suitable for powder dry materials and fine particle dry materials, such as high humidity and high viscosity materials, high temperature materials need to be customized separately.

4. The safety should be paid attention to when starting, and the hand should not be extended to the rotor part.
