The principle of star type ash discharge valve

The star-type ash unloading valve is also called an electric lock gas valve, a star unloader, a rotary feeder, a lock gas valve, and usually the star unloader is composed of a rotor impeller with several blades, a housing, and a seal. And reducer, motor and other components. 1. When the material in the upper silo falls by its own weight and fills in the gap between the blades, it is discharged in the lower part as the blades rotate. Therefore, the star unloader can discharge quantitatively and continuously. Second, the star unloader is commonly used in the pneumatic output system. For the pressure output system or the negative pressure output system, the star unloader can feed the feeding pipe evenly and continuously to ensure the gas and solid in the pneumatic output pipe. It is relatively stable, so that the pneumatic conveying can work normally. At the same time, the air pressure of the upper and lower parts of the unloader can be cut off to play the role of air lock. Therefore, star unloaders are commonly used in pneumatic conveying systems. Third, the star unloader can be used in the collection of material systems as a hopper discharger. The star unloader is currently an advanced unloading device in the country. It is commonly used in dedusting systems as one of the important equipments for dedusting systems. The unloader is particularly suitable for dust, small granular materials, and is deeply influenced by environmental protection, metallurgy, chemical industry, food, Engineering projects such as cement, road construction and drying equipment are preferred. The upper and lower flanges of the star-type ash discharge valve are basically square or round and can also be selected by the user. Its advantages are: stable and reliable work, uniform and accurate unloading, structural optimization, small size, good sealing performance, easy maintenance, light energy saving, long service life and so on. It is also one of the indispensable equipments for drying, dust, granules and solids conveying equipment. The star-type ash unloading valve relies on the gravitational effect of the material and the forcible action of the feeder's working mechanism to discharge the material in the hopper and feed it continuously and evenly into the next device. The star-type ash discharge valve is mainly composed of a motor, a speed reducer, a housing, an impeller, a main shaft, a bearing, and a left and right end caps. Adopt high quality steel plate welding structure, the blade has strong wear resistance, and the transmission device, transmission shaft and blade are integrated.
