purpose The unloading device is the main equipment for dust removal, air supply and other equipment feeding for dust removal equipment, and is suitable for powdery materials and pellets. Classification: the discharger is mainly divided into A type unloader and B type unloader. Working principle The discharger is divided into three categories: ordinary type, pressure resistant type and high temperature resistant type. The unloader can be driven at constant speed, continuously discharging material according to the control rate, or driven at an indefinite speed, and the unloading device is used as a feeder. Unloader general type: can be used in the ordinary material below 150 degrees and normal temperature, can supply material continuously and evenly to the feeding tube, and in the system and separation and dust collection, it can be used as the discharging device.
Unloader pressure resistance: it adopts a closed rotor, which can be widely used in suction, pressure delivery and negative pressure conveying equipment. The rotary unloader can ensure that the air pressure in the conveying pipe does not leak, and can safely transport and collect the material. So in this respect, it is called a ten thousand lock gas device, it can not only withstand pressure. At the same time, it has common function. Working principle First, the star type unloader is usually used in the pneumatic output system. For the pressure output system or the negative pressure output system, the star type discharger can supply the material continuously to the feeding tube. In order to ensure the gas and solid in the pneumatic output pipe, the gas and solid are stable, so that the pneumatic conveying can work normally. At the same time, the pressure of the upper and lower parts of the discharger can be separated to play the role of locking gas. Therefore, star type discharger is an important component in pneumatic conveying system.
Two. When the material in the upper silo is dropped by weight, it is filled in the gap between the blades and is discharged at the bottom with the rotation of the blades. Therefore, the star discharger can be discharged quantitatively and continuously. Three, the star type discharger can be used in the material collection system as the unloading device of the bin. Star type unloader is the most advanced unloading device in China. It is often used as an important equipment in the dust removal system. It is especially suitable for dust, small particle material, and is well chosen for the engineering projects of environmental protection, metallurgy, chemical industry, grain, cement, road building, drying equipment and so on. Four. The temperature of the material that it conveyed can reach 280 degrees C. There is a certain isolation between the bearing and the impeller at both ends, which can prevent the contact between the ultrafine powder and the bearing. The temperature of high temperature discharger conveyed material can reach 500 degrees C and connected by chain wheel. There is a certain distance between the reducer and the shell of the discharger. The structure of star type discharger is composed of rotor impeller, shell, seal, reducer, motor and so on. The star type unloader is also called rotating feeder, lock valve, star type discharging valve, star type feeder, and wind regulator.
