旋轉供料器（又稱關風機、旋轉閥、星形卸料器等）是一種用于散狀物料輸送的關鍵設備，其工作原理基于機械旋轉與氣力協同作用，實現物料的連續、定量供給。以下是其核心工作原理及特點的綜合分析：

　　A rotary feeder (also known as a shut-off fan, rotary valve, star shaped unloader, etc.) is a key equipment used for conveying bulk materials. Its working principle is based on the synergistic effect of mechanical rotation and pneumatic force, achieving continuous and quantitative supply of materials. The following is a comprehensive analysis of its core working principle and characteristics:

　　1. 基本工作原理

　　1. Basic working principle

　　旋轉供料器通過帶有數個葉片的轉子在圓筒形機殼內旋轉，物料從上部料斗落入葉片間的空格內，隨轉子旋轉至下部卸出。機體側面設有均壓排氣口，用于排出葉輪旋轉時產生的高壓氣體，避免氣體頂料現象，確保物料順利下落134。

　　The rotary feeder rotates inside a cylindrical casing through a rotor with several blades. The material falls from the upper hopper into the space between the blades and is discharged from the lower part as the rotor rotates. There is a pressure equalization exhaust port on the side of the body, which is used to discharge the high-pressure gas generated during the rotation of the impeller, avoiding the phenomenon of gas topping up and ensuring the smooth falling of materials.

　　動力來源：電機通過減速機驅動轉子旋轉，葉片的離心力將物料推向出料口，實現定量供給24。

　　Power source: The motor drives the rotor to rotate through the reducer, and the centrifugal force of the blades pushes the material towards the discharge port, achieving a quantitative supply of 24.

　　密封設計：葉片外緣常鑲有橡膠條或耐磨材料，增強葉輪與機殼間的密封性，減少漏氣或物料泄漏25。

　　Sealing design: Rubber strips or wear-resistant materials are often embedded on the outer edge of the blades to enhance the sealing between the impeller and the casing, reducing air or material leakage by 25%.

　　2. 氣力輸送中的關鍵作用

　　2. Key role in pneumatic conveying

　　在氣力輸送系統（壓送式或吸送式）中，旋轉供料器兼具供料和鎖氣功能：

　　In pneumatic conveying systems (pressure or suction), the rotary feeder has both feeding and air locking functions:

　　均壓排氣：通過排氣口平衡系統壓力，防止氣體反沖影響物料流動16。

　　Equal pressure exhaust: Balance the system pressure through the exhaust port to prevent gas recoil from affecting material flow.

　　連續供料：可穩定向輸送管道供料，同時在分離、收塵環節作為卸料器使用56。

　　Continuous feeding: It can stably supply material to the conveying pipeline and also serve as an unloader in the separation and dust collection processes.

　　3. 結構組成

　　3. Structural composition

　　主要部件包括：

　　The main components include:

　　主閥：含殼體、端蓋、葉輪及密封結構；

　　Main valve: including shell, end cover, impeller and sealing structure;

　　驅動系統：電機減速機、鏈輪等；

　　Drive system: motor reducer, sprocket, etc;

　　輔助裝置：抽氣室（排出多余氣體）、加速室（減少壓力損失）等157。

　　Auxiliary devices: exhaust chamber (to discharge excess gas), acceleration chamber (to reduce pressure loss), etc. 157.

　　4. 應用特點

　　4. Application features

　　適應性廣：可通過調整轉速調節供料量，適用于高溫、高磨耗性物料（如金屬粉末、粘性物料）457。

　　Wide adaptability: The feeding amount can be adjusted by adjusting the speed, suitable for high temperature, high abrasion materials (such as metal powder, viscous materials) 457.

　　低破碎率：葉片設計減少物料破碎，適合易碎顆粒4。

　　Low crushing rate: The blade design reduces material crushing and is suitable for fragile particles.

　　自動化集成：可與振動給料機、傳感器等配合，實現自動化控制37。

　　Automation integration: It can be combined with vibrating feeders, sensors, etc. to achieve automated control.

　　5. 優化方向

　　5. Optimization direction

　　現代旋轉供料器通過材料升級（如耐磨襯套）、結構改進（偏置轉子防卡）及智能控制（傳感器監測）提升效率與壽命57。 總結來看，旋轉供料器通過機械旋轉與氣壓平衡的協同，實現了高效、穩定的物料輸送，廣泛應用于化工、糧食加工、冶金等領域。

　　Modern rotary feeders improve efficiency and lifespan through material upgrades (such as wear-resistant liners), structural improvements (biased rotor anti jamming), and intelligent control (sensor monitoring). In summary, the rotary feeder achieves efficient and stable material transportation through the synergy of mechanical rotation and air pressure balance, and is widely used in fields such as chemical engineering, grain processing, metallurgy, etc.
