卸料器又稱(chēng)關(guān)風(fēng)器，在負壓氣力輸送中，為了保證管道處于負壓狀態(tài)，在卸料時(shí)應避免跑風(fēng)，因此它是使卸料器或除塵器在有壓力差的情況下能夠順利地排出物料，而又不致泄漏空氣的一種設備；常用的閉風(fēng)器有葉輪式閉風(fēng)器、料封壓力門(mén)閉風(fēng)器、絞龍閉風(fēng)器等。

　　Unloader, also known as air damper, is a device used in negative pressure pneumatic conveying to ensure that the pipeline is in a negative pressure state and to avoid air leakage during unloading. Therefore, it is a device that enables the unloader or dust collector to smoothly discharge materials under pressure differences without leaking air; Commonly used air closers include impeller type air closers, material sealed pressure door air closers, and screw type air closers.

　　葉輪式閉風(fēng)器是氣力輸送裝置中一種關(guān)鍵性的設備，它要求有良好的氣密性能、排料要連續、不易破碎物料、外形尺寸要小等；山東匯科智能設備根據使用工藝生產(chǎn)出不同型號、高度、功能的葉輪式閉風(fēng)器。

　　The impeller type air damper is a critical equipment in pneumatic conveying devices, which requires good air tightness, continuous discharge, materials that are not easily broken, and small external dimensions; Shandong Huike Intelligent Equipment produces different models, heights, and functions of impeller type air compressors according to the usage process.

　　葉輪閉風(fēng)器是由葉輪和圓筒形外殼組成（根據需求也有方口型），外殼的上端為進(jìn)料口與卸料器管道連接，當葉輪緩慢地轉動(dòng)時(shí)，物料不斷的地落入兩葉片之間的格室內且隨著(zhù)葉片旋轉到下端的出口排出。

　　The impeller fan is composed of an impeller and a cylindrical housing (also available in square mouth shape according to requirements). The upper end of the housing is connected to the feeding port and the discharge pipe. When the impeller rotates slowly, the material continuously falls into the compartment between the two blades and is discharged from the outlet at the lower end as the blades rotate.

　　葉輪式閉風(fēng)器的排料量，在低轉速即旋轉葉片的圓周速度在較低范圍內時(shí)，與轉速大至成正比；但超過(guò)某一轉速、排料量則隨著(zhù)轉速的增加而減少且出現不穩定現象。這是因為：當葉片的圓周速度超過(guò)某一數值時(shí)，葉片將物料飛濺開(kāi)來(lái)、使物料不能充分送入葉片之間，而已被送入葉片之間的物料可能未等排出又被葉片帶走，所以應合理控制葉輪式閉風(fēng)器的轉速，一般為30-60r/min。

　　The discharge rate of the impeller type air conditioner is directly proportional to the rotational speed when the circumferential velocity of the rotating blades is within a lower range at low speeds; But beyond a certain speed, the discharge amount decreases and becomes unstable as the speed increases. This is because when the circumferential velocity of the blades exceeds a certain value, the blades will splash the material and prevent it from being fully fed into the space between the blades. The material that has already been fed into the space between the blades may be carried away by the blades before being discharged. Therefore, the rotation speed of the impeller type air conditioner should be reasonably controlled, generally between 30-60r/min.
