旋转供料器的设计原理是将物料通过离心力沿着旋转圆盘的边缘定量供给，供给量稳定。但是，在使用旋转供料器的过程中，如果物料粘性大或者粒度过大，旋转供料器可能会出现返料现象。返料通常是由于物料在供给过程中卡住或粘在供料器的边缘和角落中无法提供，导致供料器无法提供物料，终导致旋转供料器倒转并将物料喷出。为了避免返料现象的发生，供料器的设计应考虑物料的性质，避免物料过于粘稠或颗粒过大，同时保持供料器的清洁和维修。

　　The design principle of the rotary feeder is to quantitatively supply materials along the edge of the rotating disk through centrifugal force, ensuring a stable supply. However, during the use of the rotary feeder, if the material has high viscosity or excessive particle size, the rotary feeder may experience material return. Return material is usually caused by the material getting stuck or sticking to the edges and corners of the feeder during the supply process, resulting in the feeder being unable to provide the material, ultimately causing the rotating feeder to reverse and spray the material out. In order to avoid the occurrence of material return, the design of the feeder should consider the properties of the material, avoid excessive viscosity or large particles, and maintain the cleanliness and maintenance of the feeder.

　　在选择旋转供料器时，需要根据被输送物料的性质、输送距离和输送速度来确定选型。同时，接口密封也是旋转供料器避免漏气的关键设计指标之一。

　　When choosing a rotary feeder, it is necessary to determine the selection based on the properties of the material being conveyed, the conveying distance, and the conveying speed. At the same time, interface sealing is also one of the key design indicators for preventing air leakage in rotary feeders.

　　为了避免漏气问题，旋转供料器的接口密封应根据实际条件进行主观分析。例如，可采用密封垫、密封胶等方法，以旋转供料器接口处气体泄漏。此外，旋转供料器的安装和维护也对防漏密封起到重要的作用。需要定期进行检查和维护，并严格按照使用说明操作，在操作过程中避免过度使用或抵抗液体浸泡等操作，以确保设备的正常运行和操作。

　　To avoid air leakage issues, the interface sealing of the rotary feeder should be subjectively analyzed based on actual conditions. For example, sealing gaskets, sealants, and other methods can be used to prevent gas leakage at the interface of the rotating feeder. In addition, the installation and maintenance of the rotary feeder also play an important role in leak proof sealing. Regular inspection and maintenance are required, and strict adherence to the instructions is necessary to avoid excessive use or resistance to liquid immersion during operation, in order to ensure the normal operation and functioning of the equipment.

　　气力输送设备根据不同的输送方式和形式，可以分为以下几类：

　　Pneumatic conveying equipment can be divided into the following categories based on different conveying methods and forms:

　　1. 压缩空气输送设备：利用压缩空气将物料输送到相应位置的设备，主要特点为输送速度快、输送距离远，适用于粉状或颗粒状物料的长距离输送。

　　1. Compressed air conveying equipment: a device that uses compressed air to transport materials to corresponding positions. Its main characteristics are fast conveying speed and long conveying distance, suitable for long-distance conveying of powdered or granular materials.

　　2. 负压气力输送设备：通过负压控制，在系统内建立负压，将物料筛选、输送和收集，主要特点为使用方便、经济节能、适用于粉末和颗粒物料的输送。

　　2. Negative pressure pneumatic conveying equipment: Through negative pressure control, negative pressure is established in the system to screen, transport, and collect materials. Its main features are convenient to use, economical and energy-saving, and suitable for conveying powder and granular materials.

　　3. 正压气力输送设备：建立正压系统，将物料输送到需要的位置，主要适用于粉状和颗粒状物料的输送，具有传输效率高、精度高的优点。

　　3. Positive pressure pneumatic conveying equipment: Establish a positive pressure system to transport materials to the required location, mainly suitable for conveying powdered and granular materials, with the advantages of high transmission efficiency and high accuracy.

　　4. 集中式气力输送系统：在生产线上设置集中输送系统，建立一个主控制系统和多个分支控制系统，实现多物料的集中输送和集中控制，主要适用于对生产线效率要求高、物料多种多样的制造行业。

　　4. Centralized pneumatic conveying system: Install a centralized conveying system on the production line, establish a main control system and multiple branch control systems, and achieve centralized conveying and control of multiple materials. It is mainly suitable for manufacturing industries that require high production line efficiency and diverse materials.

　　总之，气力输送设备用途广泛，适用于多种物料的输送，能有效提高生产效率和输送效率，是当前工业领域的设备。

　　In short, pneumatic conveying equipment has a wide range of applications and is suitable for conveying various materials. It can effectively improve production efficiency and conveying efficiency, and is currently the equipment in the industrial field.
