垂直正压关风器由正压关风器和料⽓混合加速器组成，关风器采⽤上进料垂直出料设计，物料经过加速器⾼效流化，输送管道不堵塞，其内部空⽓流的设计⼤⼤提⾼了输送效率和使⽤寿命，避免了物料对关风器内部的冲击和磨蚀，适⽤于物料⽐较重、磨蚀性较强的颗粒物料输送。

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.
