你是否真的了解旋转供料器结构特性呢?

  旋转供料器,常被称为关风机、卸料器、旋转给料阀、旋转卸料阀、旋转阀等,是散状物料输送过程中的关键设备。凭借运行可靠、成本适宜等特点,被广泛应用于粮食加工、化工原料、塑料冶金、能源矿业、建材水泥、码头等多个领域。在啤酒生产的麦芽车间、酿造车间中,输送大麦、麦芽等物料时,也普遍采用旋转供料器完成物料转运。

  Rotary feeders, commonly known as shut-off fans, unloaders, rotary feed valves, rotary discharge valves, rotary valves, etc., are key equipment in the process of conveying bulk materials. Due to its reliable operation and suitable cost, it is widely used in various fields such as grain processing, chemical raw materials, plastic metallurgy, energy mining, building materials and cement, docks, etc. In the malt and brewing workshops of beer production, rotary feeders are commonly used to transport materials such as barley and malt.

  旋转供料器主要由主阀(包含壳体、端盖、叶轮、密封结构等部件)、电机减速机、防护装置(如链轮、链轮罩等)以及排气口等部分构成。其配套组件包括抽气室、加速室、防卡进料器等。这类设备又称星型给料器、旋转给料机、锁气器等,其核心结构与工作原理是通过带有多个叶片的转子在圆形机壳内转动,将上部料斗中的物料通过叶片间的空隙旋转运送至下部排出。在风力输送系统(包括压送式和吸送式)中,旋转供料器不仅要完成卸料功能,还需避免高压气体通过供料器泄漏到上部料仓,防止影响物料下落。因此,它是气力输送系统中的重要组成部分,既能向输料管中均匀、连续地定量供料,实现物料输送;又能在系统的分离收尘部分发挥卸料器的作用。

  The rotary feeder mainly consists of the main valve (including housing, end cover, impeller, sealing structure, etc.), motor reducer, protective device (such as sprocket, sprocket cover, etc.), and exhaust port. Its supporting components include an exhaust chamber, an acceleration chamber, an anti jam feeder, etc. This type of equipment is also known as star feeders, rotary feeders, air locks, etc. Its core structure and working principle are to rotate a rotor with multiple blades inside a circular casing, and transport the material in the upper hopper through the gaps between the blades to the lower part for discharge. In wind conveying systems (including pressure feeding and suction feeding), the rotating feeder not only needs to complete the unloading function, but also needs to prevent high-pressure gas from leaking into the upper material bin through the feeder to prevent it from affecting the falling of materials. Therefore, it is an important component of the pneumatic conveying system, which can evenly and continuously supply materials to the conveying pipe in a quantitative manner, achieving material conveying; It can also play the role of an unloader in the separation and dust collection part of the system.

  主要机型特性

  Main model characteristics

  防卡型:采用防卡进料结构设计,能根据不同物料特性调整间隙,必要时采用偏置式机体、镶片式转子或 V 型转子,具备防卡堵和减少物料破碎的功能,可通过多种防卡设计组合提升适用性。

  Anti jamming type: Adopting an anti jamming feeding structure design, the gap can be adjusted according to the characteristics of different materials. If necessary, a biased body, embedded rotor or V-shaped rotor can be used, which has the functions of anti jamming and reducing material breakage. Multiple anti jamming design combinations can be used to improve applicability.

  耐压型:配备封闭型转子,广泛应用于吸送式、压送式气力输送系统,能有效降低漏气量,保障气力输送系统的稳定运行,尤其适用于对气压密封性要求较高的场景。

  Pressure resistant type: equipped with a closed rotor, widely used in suction and compression pneumatic conveying systems, can effectively reduce air leakage and ensure stable operation of the pneumatic conveying system, especially suitable for scenarios with high requirements for air pressure sealing.

  耐温型:采用外装式结构设计,将运转部件与接触物料的箱体部分分离,使轴承和油封系统免受高温影响,确保设备正常工作。该机型还特别适合输送金属粉末和超细粉料,可避免这类物料侵入轴承和油封系统造成损坏。

  Temperature resistant type: Adopting an external structural design, the operating components are separated from the box body that comes into contact with the material, which protects the bearing and oil seal system from high temperatures and ensures the normal operation of the equipment. This model is particularly suitable for conveying metal powder and ultrafine powder materials, which can prevent such materials from entering the bearing and oil seal system and causing damage.

  防粘型:通过特殊结构设计,能稳定输送易粘连、易结块的物料,解决传统设备在处理这类物料时出现的堵塞问题。

  Anti sticking type: Through special structural design, it can stably transport materials that are prone to adhesion and clumping, solving the problem of blockage that traditional equipment encounters when handling such materials.

  中高压旋转供料器包含主机、连接侧板、链轮、链条、链罩等部件。接料器与供料器是使物料与空气混合并送入输料管的设备,是风力输送装置的关键环节。接料器的结构合理性,直接影响整个风力输送装置的输送量、运行稳定性及能耗高低。因此,根据装置的不同工作条件,正确设计和选用合适的接料器,是提升风力输送效果的重要举措。

  The medium and high pressure rotary feeder includes components such as the main engine, connecting side plates, chain wheels, chains, and chain covers. The feeder and receiving device are equipment that mix materials with air and feed them into the conveying pipe, and are key components of the wind powered conveying system. The rationality of the structure of the feeder directly affects the conveying capacity, operational stability, and energy consumption of the entire wind conveying device. Therefore, designing and selecting appropriate feeders according to the different working conditions of the device is an important measure to improve the effectiveness of wind conveying.
