The vertical positive pressure airlock is composed of a positive pressure airlock and a material-gas mixing accelerator. The airlock adopts the design of upper feeding and vertical discharging. The material is efficiently fluidized by the accelerator, and the conveying pipeline is not blocked. The design of the internal air flow greatly improves the conveying efficiency and service life, and avoids the impact and abrasion of the material on the inside of the airlock. It is suitable for conveying granular materials with heavy materials and strong abrasiveness.
