　　旋转供料器是气力输送系统(正压/负压)的核心枢纽，精准定量给料的同时实现高压气密封，转子与阀体的精密配合让物料输送更稳定高 效。搭配抽气室平衡压差、加速室提升混合效率，配合金属补偿器吸收管路位移，整套系统犹如精密齿轮协同运转，确保粉末颗粒输送流畅无阻。

　　The rotary feeder is the core hub of the pneumatic conveying system (positive/negative pressure), which accurately quantifies the material while achieving high-pressure gas sealing. The precise fit between the rotor and valve body makes the material conveying more stable and efficient. Paired with an exhaust chamber to balance pressure difference and an acceleration chamber to improve mixing efficiency, and a metal compensator to absorb pipeline displacement, the entire system operates like a precision gear to ensure smooth and unobstructed transportation of powder particles.

　　Function of high-precision sealed rotary feeder:

　　Airtight seal (closed air lock): The precise fit between the impeller and the shell can effectively prevent high-pressure or positive/negative pressure airflow in the conveying pipeline from entering the silo in the opposite direction, maintain pressure balance in the system, and reduce airflow loss.

　　Quantitative unloading: The material in the silo is uniformly and continuously conveyed to the acceleration chamber or conveying pipeline below through a rotating impeller, controlling the amount of material conveyed.

　　Unloading and ash discharge: As a dust collector or bottom equipment of the silo, it smoothly discharges the collected dust or materials to prevent bridge blockage.

　　Function of the rotary feeder suction chamber:

　　Pressure relief and anti toppling material: Timely extract the high-pressure gas leaked from the positive/negative pressure conveying side through the impeller gap to the feeding side, to avoid the interruption or fluctuation of feeding caused by the gas lifting the powder upward.

　　Improve sealing effect: reduce the impact of airflow on the gap seal between the rotating impeller and the shell, reduce the probability of material being blown back or dispersed by the airflow, and enhance the air locking and feeding capacity of the feeder.

　　Stable conveying state: To avoid fluctuations in the feeding amount caused by pressure imbalance, ensure that materials enter the conveying pipeline continuously and evenly, and maintain the overall conveying efficiency of the system.

　　Rotating feeder acceleration chamber function:

　　Stable conveying conditions: By optimizing the mixing ratio and speed of materials and airflow, the movement resistance of materials in the pipeline is reduced, ensuring continuous and smooth subsequent conveying processes and avoiding conveying fluctuations caused by uneven material speeds.

　　Material acceleration: Receive static or low-speed materials flowing out of the rotor impeller, and use the high-pressure airflow of the Roots blower introduced from the bottom to achieve the required speed for suspended transportation in a very short distance, avoiding accumulation at the pipe mouth due to insufficient initial velocity.

　　Gas solid mixing: Provides turbulent space for the conveying air to fully mix with powder/particles, forming a stable dilute or dense phase flow state, ensuring smooth entry of materials into horizontal or vertical pipelines.

　　Function of metal compensator:

　　Installed on the connecting pipeline (such as the inlet and outlet pipelines of the rotary feeder), utilizing the elastic deformation of metal corrugated pipes to absorb thermal expansion and contraction displacement, compensate for installation errors, reduce vibration and noise, and protect the rotary feeder and pipeline interface from leakage or damage due to stress deformation. The rotary feeder itself does not include the core component of "metal compensator"; The two are independently installed components with different functions in the pneumatic conveying system: the rotary feeder is responsible for quantitatively locking the air feeding, and the metal compensator (usually referring to the corrugated compensator) is responsible for absorbing the thermal displacement and vibration of the pipeline. ‌‌
