在现代工业生产的复杂体系中，物料的高效、精准输送是保障生产流程顺畅运行的关键环节。旋转供料器，作为一种核心的物料输送设备，正悄然在各个行业中发挥着不可替代的重要作用。它以独特的工作方式和卓越的性能，为散状物料的稳定传输提供了可靠保障，犹如工业生产的 “物料输送枢纽”，连接着生产过程中的各个阶段。​

In the complex system of modern industrial production, efficient and precise transportation of materials is a key link to ensure the smooth operation of the production process. Rotary feeders, as a core material conveying equipment, are quietly playing an irreplaceable and important role in various industries. It provides reliable guarantee for the stable transportation of bulk materials with its unique working mode and excellent performance, like a "material conveying hub" in industrial production, connecting various stages of the production process. ​

旋转供料器基础认知​

旋转供料器，在行业内也常被称为关风机、卸料器、旋转给料阀、旋转卸料阀或旋转阀等，是专门用于散状物料输送的重要设备。其工作原理基于巧妙的机械设计，利用带有数个叶片的转子在圆筒形机壳内的旋转运动，实现物料的连续输送。​

Rotary feeders, also commonly known as shut-off fans, unloaders, rotary feed valves, rotary discharge valves, or rotary valves in the industry, are important equipment specifically used for conveying bulk materials. Its working principle is based on clever mechanical design, utilizing the rotational motion of a rotor with several blades inside a cylindrical casing to achieve continuous material conveying. ​

从外观上看，旋转供料器通常呈现出紧凑的结构设计，整体造型较为规整，以适应不同的安装空间和工作环境。它的尺寸大小根据实际应用场景和物料处理量的需求有所不同，小到适用于实验室等小型作业场景的迷你型设备，大到能够满足大型工业生产线大规模物料输送的大型设备。​

From the appearance, the rotary feeder usually presents a compact structural design with a relatively regular overall shape to adapt to different installation spaces and working environments. Its size varies depending on the actual application scenario and material processing requirements, ranging from mini equipment suitable for small work scenarios such as laboratories to large equipment capable of meeting large-scale material transportation in industrial production lines. ​

物料填充与输送过程​

Material filling and conveying process

当物料从上部料斗进入旋转供料器时，在重力的作用下，迅速落入转子叶片间的空格内。此时，转子在电机减速机的驱动下，以稳定的转速开始旋转。随着转子的转动，填充在叶片空格内的物料被逐渐带向机壳的下部。在这个过程中，叶片起到了承载和推动物料的关键作用，它们如同一个个小型的 “物料搬运工”，将物料从进料口平稳地转移到出料口。例如，在面粉加工厂中，小麦粉从储存仓通过旋转供料器的进料口进入，转子叶片将其逐一承接，并在旋转过程中输送至出料口，再进入后续的加工环节，确保了面粉生产流程的连续性。​

When the material enters the rotary feeder from the upper hopper, it quickly falls into the space between the rotor blades under the action of gravity. At this point, the rotor starts rotating at a stable speed under the drive of the motor reducer. As the rotor rotates, the material filled in the blade space is gradually carried towards the lower part of the casing. In this process, the blades play a crucial role in carrying and pushing materials, acting like small "material handlers" that smoothly transfer materials from the inlet to the outlet. For example, in a flour processing plant, wheat flour enters from the storage bin through the feed inlet of the rotary feeder. The rotor blades receive it one by one and transport it to the discharge outlet during the rotation process before entering the subsequent processing steps, ensuring the continuity of the flour production process. ​

均压排气机制​

Equal pressure exhaust mechanism

在转子旋转的过程中，叶轮回转会不可避免地带来高压气体，这些气体若不能及时排出，会在机壳内部形成压力堆积，产生气体顶料现象，阻碍物料的顺利下落。为解决这一问题，旋转供料器在机体侧面专门设置了均压吸气口。通过这个吸气口，叶轮回转产生的高压气体能够被及时吸走，使机壳内部的气压保持平衡，为物料的顺畅下落创造了良好的条件。以水泥生产为例，在将水泥生料输送至窑炉的过程中，旋转供料器的均压吸气口能够有效消除因转子旋转产生的气压干扰，确保生料能够稳定、高效地进入窑炉，为水泥的烧制提供稳定的原料供应。

During the rotation of the rotor, the rotation of the impeller inevitably brings high-pressure gas. If these gases cannot be discharged in time, they will form pressure accumulation inside the casing, resulting in gas top material phenomenon and hindering the smooth falling of materials. To solve this problem, the rotary feeder is specially equipped with a pressure equalization suction port on the side of the machine body. Through this suction port, the high-pressure gas generated by the rotation of the impeller can be sucked away in a timely manner, keeping the pressure inside the casing balanced and creating favorable conditions for the smooth falling of materials. Taking cement production as an example, during the process of transporting cement raw materials to the kiln, the uniform pressure suction port of the rotating feeder can effectively eliminate the pressure interference caused by the rotation of the rotor, ensuring that the raw materials can enter the kiln stably and efficiently, providing a stable supply of raw materials for cement firing.
