Star discharging device? A, star discharge device, also known as the star dust unloading valve, star under the feeder, rotary feeder, lock valve, usually star-shaped discharge structure is made with a number of blades impeller rotor housing, seals and reducer, motor and other components. Second, when the upper material hopper falls by gravity in the gap between the blades is filled in, with the rotation of the blade in the lower part of discharge, therefore, star discharge can quantitatively and continuously discharging. Third, the star is often used in pneumatic unloader output system, for pressure or vacuum output system output system, star discharge can be uniformly and continuously fed to the conveying pipe, in order to ensure air pneumatic output tube, solid relatively stable, so that the pneumatic conveying can work, at the same time, but the upper and lower discharge pressure off the air lock and play the role. Therefore, star discharge is an important component of pneumatic conveying systems commonly used. Fourth, star discharge system can be used in the collection of material, as a silo unloader. Star unloader is currently the most advanced discharging device, commonly used in dust removal system as one of the important equipment dust removal system, which is particularly suitable for dust, small particles of material, by environmental protection, metallurgy, chemical industry, food, cement , roads, drying equipment and other industries to select the best projects. Fifth, the star unloader, the next flanged base is square or round, can also be selected by the user. Six, wear-resistant closed rotor wheel star unloader of this type is characterized by the ends of the rotor blades seal liner polyvinyl fluoride, and the portion of the blade to ensure good contact with the inner wall of the housing, can be easily adjusted after the wear of the blade and ends, so that it remains in good contact with the inside of the housing, the air lock has better performance. Seven, temperature temperature type it up delivery of materials bearing 280 ° C at both ends of the impeller has a certain isolation, ultra-fine powder to prevent contact with the bearing. High temperature type temperature transport of materials up to 500 ° C, using sprocket connected, and unloading gear housing a certain distance.
