旋转式供料器是稀相气力输送系统常用供料或卸料设备，旋转式供料器的组成有叶轮、机壳、电机、减速机、防护罩、链条、底坐、抽气室、加速室等，根据现场所在工艺有不同类型，故其配制有所差异。

　　The rotary feeder is a commonly used feeding or unloading equipment in dilute phase pneumatic conveying systems. The composition of the rotary feeder includes impellers, casings, motors, reducers, protective covers, chains, bottom seats, suction chambers, acceleration chambers, etc. The configuration varies depending on the process on site.

　　旋转式供料器又称为锁气器、关风机、旋转阀、星形卸料器等，壳体两端用端盖密封、壳体的上部分为进料口、下部为出料口；叶轮一般有6-12个叶片，使机壳内空间分为6-12格室；当叶轮通过传动装置在壳体旋转时，物料从进料口进入叶轮的空腔（格室）内，随着叶轮旋转从下部出料口卸出。

　　Rotary feeders, also known as air locks, shut-off fans, rotary valves, star shaped unloaders, etc., are sealed at both ends of the shell with end caps. The upper part of the shell is the feeding port and the lower part is the discharging port; The impeller generally has 6-12 blades, dividing the space inside the casing into 6-12 compartments; When the impeller rotates in the housing through the transmission device, the material enters the cavity (compartment) of the impeller from the feed port and is discharged from the lower discharge port as the impeller rotates.

　　在压送气力输送系统中，因为管道系统内部的空气压强高于大气压，故旋转给料器属于强制供料，强制供料的特点使得旋转给料器成为压送气力输送系统首先的供料器，为区别其他系统内的供料器，压送气力输送中的旋转供料器又称为正压关风机，此类气力输送设备常有叶轮、机壳、电机、减速机、防护罩、链条、抽气室、底座、加速室等组成。

　　In the pneumatic conveying system, due to the air pressure inside the pipeline system being higher than atmospheric pressure, the rotary feeder belongs to forced feeding. The characteristics of forced feeding make the rotary feeder the first feeder in the pneumatic conveying system. To distinguish it from feeders in other systems, the rotary feeder in pneumatic conveying is also known as a positive pressure shut-off fan. Such pneumatic conveying equipment often consists of impellers, casings, motors, reducers, protective covers, chains, suction chambers, bases, acceleration chambers, etc.

　　在负压气力输送系统中，用于末端除尘器卸料设备，需锁气以免漏气影响系统的整体稳定性，常采用背包旋转式供料器，此类气力输送设备有叶轮、机壳、电机、减速机、防护罩、链条、连接板等组成。

　　In the negative pressure pneumatic conveying system, used for the discharge equipment of the end dust collector, it is necessary to lock the air to prevent air leakage and affect the overall stability of the system. A backpack rotary feeder is often used. This type of pneumatic conveying equipment consists of impellers, casings, motors, reducers, protective covers, chains, connecting plates, etc.

　　除此外，还有贯通型、防卡型、标准型等旋转式供料器，其组成基本相同，根据使用场合略有调整，恒通粉体自主研发、生产、销售各类型旋转供料器且免费设计粉粒物料气力输送方式，若需要请随时联系我们。

　　In addition, there are also rotary feeders such as through type, anti jam type, and standard type, which have basically the same composition and may be slightly adjusted according to the usage scenario. Hengtong Powder independently develops, produces, and sells various types of rotary feeders, and designs free pneumatic conveying methods for powder particles.
