Product introduction

The star type discharger is installed at the discharge port of the discharger working under negative pressure. The upper part receives the materials discharged by the discharger. The rotating impeller plays the role of conveying materials, and also plays the role of sealing. It prevents air from being inhaled from the discharge port in the process of pneumatic conveying, so as to ensure the normal discharge of the discharger. As a special unloading equipment, star unloader plays an important role in cleaning and cleaning.

Structure composition

Usually, the structure of star type discharging is composed of rotor impeller, shell, seal, reducer and motor with several blades. Star type discharging device is also called rotary feeder, air lock valve, star type discharging valve, star type discharging device and air shut-off device.

working principle

1. Star discharger is often used in pneumatic output system. For pressure output system or negative pressure output system, star discharger can supply material to the conveying pipe evenly and continuously. In order to ensure that the gas and solid in the pneumatic output pipe are relatively stable, so that the pneumatic conveying can work normally. At the same time, the air pressure at the upper and lower parts of the discharger can be cut off to lock the air. Therefore, star discharger is an important part in pneumatic conveying system.

2. When the material in the upper bin falls by its own weight, it fills the gap between the blades and is discharged at the lower part with the rotation of the blades. Therefore, the star unloader can discharge material quantitatively and continuously.

3. The star discharger can be used in the material collection system as the discharger of the silo. Star discharger is the current discharge device, which is often used in the dust removal system as one of the important equipment of the dust removal system. It is especially suitable for dust and small particle materials. It is widely used in engineering projects of environmental protection, metallurgy, chemical industry, grain, cement, road construction, drying equipment and other industries.

4. The temperature of the material it transports can reach 280 ℃ ° The bearings at both ends of C are isolated from the impeller to prevent the powder from contacting with the bearing. The temperature of conveying material can reach 500 ℃ ° C. Chain wheel connection is adopted. There is a certain distance between the reducer and the shell of the discharger.

main features 

1. Compact structure, beautiful appearance, easy to use.

2. Stable operation and low noise.

3. Due to the distance between the bearing and the gearbox from the housing, the lubrication is greatly improved for high temperature.

4. It can be designed and manufactured according to user's requirements.

5. Before leaving the factory, the product is filled with special grease for cycloid reducer. Please check and refuel regularly.
