Description of unloader:

Star discharger used to install the discharger work under negative pressure discharging mouth, upper accept discharger discharge materials, rely on the rotating impeller conveying material plays a role, and assuming the role of sealing, prevent from the discharging mouth breathing the air in the process of pneumatic conveying, guaranteeing the normal discharge of the discharger as a special kind of unloading equipment, in the cleaning and washing work has played a big role.So it is necessary for us to summarize some characteristics of it, so you can better understanding of the star discharger do comprehensive and maintenance, its biggest ability into full play.

Advantages of unloader :
1,Smooth running, low noise.
2,Compact structure, beautiful appearance, easy to use.
3,Due to some distance, bearing, gear box away from shell to high temperature, lubrication are improved substantially.

Working principle of unloader :
1,star discharger commonly used in pneumatic output system, the pressure output system or negative pressure output system, star discharger can evenly, continuously to the transporting pipe feeding.Strength to ensure that the output pipe of the gas and solid is stable, so that the pneumatic conveying can work normally, at the same time, and on the discharger, locking air partition and the lower air pressure.As a result, the star discharger is an important part of a pneumatic transportation system commonly used in.
2, when the upper house of the material by gravity fall in filling the gap between the blade, in the lower discharge with the rotation of the blade.Therefore, star discharger can quantitatively and continuously discharging.
3,star discharger can be used in collecting the material system, as the bunker discharger.Star discharger is currently the most advanced discharging device, commonly used in dust removal system as one of important equipment of dust removal system.It is particularly suited to dust, small granular materials, by environmental protection, metallurgy, chemical industry, food, cement, building roads, drying equipment and other industries project select.
4, heat-resistant type conveying material by its temperature can reach 280 ° C on both ends of bearing and impeller have certain isolation, can prevent the superfine powder and the bearing contact.High temperature resistant type discharger conveying material temperature can reach 500 ° C, connected by sprocket.Reducer and discharger shell has certain distance.
