YJD-A star shaped unloader

The YJD-A star shaped unloader is a mechanism composed of an impeller, housing, end cover, bearings, and other components. And the clearance between the impeller and the outer shell is small, which can meet the requirements of air lock and achieve good dust removal effect. In the dust removal system, as one of the important dust removal equipment, it mainly transports powder materials, granular materials, raw materials, etc., and is widely used in industrial sectors such as environmental protection, metallurgy, chemical industry, grain, and food.

The YJD-A star shaped unloader is suitable for continuously and smoothly discharging dust or particulate matter under pressure into the atmosphere, and is an important equipment in pneumatic conveying and ventilation dust removal networks. The main working component of the star shaped unloader is the rotating impeller, which not only transports materials but also serves as a seal. It has the characteristics of beautiful and elegant appearance, compact and reasonable structure, stable and excellent use, light weight, large capacity, and low power consumption.

YJD-A star shaped unloader is commonly used in pneumatic output systems. For pressure output systems or negative pressure output systems, the star shaped unloader can uniformly and continuously supply material to the conveying pipe. To protect the stability of the gas and solid inside the pneumatic output pipe, so that the pneumatic conveying can work normally, and at the same time, it can also block the upper and lower air pressure of the unloader and play a role in air locking. Therefore, the star shaped unloader is an important component commonly used in pneumatic conveying systems.

Working principle of YJD-A star shaped unloader

When the star shaped unloader is working, dust falls by gravity and fills the star shaped blade spaces on the top and sides. The blade rotor is driven by an electric motor through a reducer to rotate the shaft, and the impeller rotates to the lower part to unload the dust by its own weight.

1、 When the material in the upper silo falls by its own weight and fills the gaps between the blades, it is discharged from the lower part as the blades rotate. Therefore, the star shaped unloader can discharge the material quantitatively and continuously.

2、 Star shaped unloading devices are commonly used in pneumatic output systems. For pressure output systems or negative pressure output systems, the star shaped unloader can uniformly and continuously feed the conveying pipe to protect the stability of the gas and solid inside the pneumatic output pipe, so that the pneumatic conveying can work normally. At the same time, it can also block the upper and lower air pressure of the unloader to lock the air.

Advantages of YJD-A star shaped unloader:

1. Compact structure, beautiful appearance, and convenient use

2. Smooth operation and low noise.

3. Due to the distance between the bearings and the gearbox from the housing, there are significant changes in lubrication for high temperatures.

4. Our factory can also design and manufacture according to user requirements.
