Wholesale supply of 500*500 rotary feeding valve square mouth electric star unloader

Star-shaped ash unloading device is currently the most advanced unloading device in China. It is commonly used in dust removal systems as one of the important equipment of dust removal systems. It is especially suitable for dust and small particle materials. It is popular among environmental protection, metallurgy, chemical industry, food, cement, road construction, etc. Engineering projects in industrial industries such as drying equipment are selected and used.
. . Star unloaders are commonly used in pneumatic output systems. For pressure output systems or negative pressure output systems, star unloaders can evenly and continuously supply materials to the feeding pipe to ensure that the contents of the pneumatic output pipe are The air and solids are relatively stable,
. . Star unloading device is also called star unloading valve
, star unloader, rotary feeder, air lock valve, usually the star unloading structure is composed of several plates The blade is composed of a rotor impeller, a shell, a seal, a reducer, and an electric motor. When the material in the upper bin falls by its own weight and fills the gap between the blades, it is discharged at the lower part as the blades rotate. Therefore, the star unloader can discharge materials quantitatively and continuously. The star unloader, also known as the rotary feeder and the air shutter, consists of a rotor with several blades rotating in a cylindrical casing. The material falling from the upper hopper is filled in the space between the blades, and then It is discharged by the rotation of the blades. Performance advantages and characteristics
This product has high processing precision and air locking function. It can be used as a powder quantitative feeder in crushing and classification systems, and as an unloader in separation, dust collection and other systems, or as a Suitable for pressure-feeding and suction-feeding pneumatic conveying systems.
, equipped with pressure balance device, can be used in positive pressure and negative pressure conveying systems.
, can be made of various materials such as cast iron, cast steel, stainless steel, titanium steel, etc., and the flange mouth can be in various structural forms such as square or circular to meet the different needs of users
. . Star discharge The upper and lower flange ports of the device are basically square or circular, and can also be selected by the user. Wear-resistant closed rotor impeller This type of star unloader is characterized by the end of the rotor blades being lined with polyfluoroethylene sealing strips, which ensures good contact between the blade ends and the inner wall of the shell, and the blade ends can be easily adjusted after wear. , so that it still maintains good contact with the inside of the shell and has better air-locking performance. The temperature-resistant type can transport materials whose temperature can reach
<

There is a certain isolation between the bearings at both ends and the impeller, which can prevent ultra-fine powder from contacting the bearings. The temperature of the high-temperature-resistant conveyed material can reach
<

,
It is connected by a sprocket, and there is a certain distance between the reducer and the unloader housing.
