YJD-A type unloader , also known as electric ash discharge valve (star-type unloader), it consists of motor, planetary planetary reducer (X) or needle loop cycloid reducer (Z) and rotary dragon unloader. The gray valve consists of three parts. There are two series with 60 specifications. The inlet and outlet flanges are of type A, and the round ones are of type B. The ash unloading valve, also known as the air shut-off device, is suitable for continuously discharging the dust or particles under pressure into the atmosphere. It is an important device in the pneumatic conveying and ventilation dust removal network. The main working part of the star-shaped ash discharge valve is a rotating impeller, which not only plays a role of conveying materials, but also plays a sealing role. The ash discharge valve has the characteristics of beautiful appearance, compact and reasonable structure, reliable use, light weight, large capacity and low power consumption.
Application range of YJD-A unloader:
The star discharger can be used in the material collection system as the discharger of the silo. The star-shaped unloader is currently an advanced unloading device in China. It is often 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 working principle of YJD-A unloader:
The star-shaped discharger supplies material to the conveying pipe to ensure that the gas and solids in the pneumatic output pipe are relatively stable, so that the pneumatic conveyance can work normally, and at the same time, the upper and lower air pressure of the discharger can be blocked to lock Pneumatic action, 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 discharger can discharge quantitatively and continuously.
