Bulk material unloading rotary valve

(4) the role of the star type unloader "one wind and more use". The utility model has the function of "one wind and multiple uses" for the discharger used for granular materials (such as raw grain). When discharging, it can also remove dust and light impurities, and has certain friction and cleaning effect on the surface of the material.

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.
