关风机(又称电动锁气器、旋转阀、星形下料器、旋转供料器、星型卸料阀、旋转卸料器、卸料器)广泛地应用于高中低压气力输送系统中，它有定量供料与锁气的功能。它利用压缩空气或罗茨鼓风机作为气源将物料从一个点输送到另一个点的技术，具有可以将由数点集中的物料送往一处或有一处送往分散的数点，并实现输送等特点，具有粉体输送等作用，关风机常用于锂电、化工、医药、塑料、食品、钢厂、电厂、水泥、环保、矿山、石油、冶金等行业。旋转供料器主要由主阀(壳体,端盖,叶轮,密封结构等),电机减速机,防护装置(链轮,链轮罩等),排气口等组成。　　风送直吹式关风机，用于粉状物料的气力输送系统中作为加料装置，由于优化设计的进料口和直吹通道，进而提高了输送量，不受转速和压力影响的高填充效率，通道压力损失小，多形式结构转子，较小化的转子间隙将泄漏量降到较低，关风机材质采用不锈钢或碳钢，经过特殊处理，可达到超强耐磨。也可喷涂碳化钨陶瓷特氟龙等;达到耐磨损、耐腐蚀。适用于各种介质在气力输送中的应用，其轴向采用多层保护或淡气隔离,确保长期安全工作。【电话/微信咨询：耿先森18706122402】         《扫二维码-添加 耿先森 微信-咨询气力输送关风机》　　Shut off fans (also known as electric air locks, rotary valves, star shaped feeders, rotary feeders, star shaped discharge valves, rotary unloaders, and unloaders) are widely used in high, medium, and low pressure pneumatic conveying systems. They have the functions of quantitative feeding and air locking. It uses compressed air or Roots blower as the gas source to transport materials from one point to another, and has the characteristics of being able to transport materials concentrated in a few points to one or dispersed points, and achieve transportation. It also has functions such as powder transportation.　　Wind turbines are commonly used in industries such as lithium batteries, chemicals, pharmaceuticals, plastics, food, steel mills, power plants, cement, environmental protection, mining, petroleum, metallurgy, etc. The rotary feeder is mainly composed of a main valve (housing, end cover, impeller, sealing structure, etc.), a motor reducer, protective devices (sprocket, sprocket cover, etc.), exhaust port, etc.
