产品结构及用途
关风机又称旋转阀、锁气器，通常呈星型结构(如图I所示)是由带有数片叶片的转子叶轮、壳体、密封件及减速器、电动机等组成。
当上部料仓的物料靠自重落下充填在叶片之间的空隙中，随叶片的旋而在下部卸出，因此，关风机可以定量而连续地卸料(如图2所示)。
关风机可以用在收集物料系统中，作为料仓的卸料器(如图4所示)，它特别适用于粉料、小颗粒物料，在正负压差吸送过程中将物料分离排出，因而深受化工、制药、干燥、粮食、水泥、环保、电力等行业的工程项目选用。

The structures and the use Commissioner Fan is also called rotary valve, air lock, usually is of the structure of star (as the picture1), is made up by some pieces of the rotor blade impeller, shell, seals, reducer and motor, elc. After materials in the upstream silo fall down by gravity to filf in with the gap between the leaves, they will be unloaded with rotation of the blade from the lower part .Therefore, Commissioner Fan can unload thematerials quantitatively and continually(as picture 2). Commissioner Fan is used in pneumatic system(as picture 3), for the compression or vacuum conveying system.
Commissioner Fan can feed materials to chute smoothfy and continuafly, to assure that the ratio of air and solid jn the pneumaic system, the sOlidls more steady, so to make the pneumatic conveying work normally, at the same time, it also can cut off the upper and lower pressure to lock the gas. Thus, Commissioner Fan is the important part which is commonly used in the pneumatic conveying syslem.
Commissioner Fan can be used in materials collection system as the discharger ofthestorage bin (as picture 4). It is applicabfe to the powder and the particle material It is suitable for positive/negative pressure diffetial suction syslem, so it is alwavs selecled to be used by the chemical,pharmaceutical, dry, food, cement, environmental protection, electric power and other sectors Of the projects.


一、丹港牌关风机的上、下法兰口基本是方形或圆形，也可以由用户选定。
二、耐磨损封闭型转子叶轮改关风机特点是转子叶片的端部采用特殊耐磨材料制成，能保证叶片端部与壳内壁的良好接触，并且磨损后可方便地调节叶片端部，使其仍然与壳体内部保持良好接触，具有更好的锁气性能。
三、耐高温型它所输送物料的温度可达300摄氏度两端轴承与叶轮有一定隔离，能防止超细粉料与轴承接触。

1 .Dangang Brand Commissioner Fan is up and down flanged. Faces are square or round. It can also be fabricatedas per thespecial requirements from customer.
2.This dosed rotor was made by exterior grinding material,can assure very well contacting with casing
3.External installed &Temperature and pressure resistance type can be fed by materials in 300℃ temperature. Bearing on twosides can't contact powder.



关风机排料量G按下式计算：Discharging capacity is calculated as per the foilowing formula
G：0.06V.N.Y.R.K（吨/小时） G: 0.06V N Y R K(ton / h)
V-关风机容积（升/转）V-volume of commissioner fan(I / r)
N-关风机转速（转/分）rotation speed of commissioner fan
Y-关风机容积效率：颗粒状物料r=0.8；粉状物料r=0.5-0.6
     Volume efficiency: r=0.8  forgranular materic  r=0.  5~0.6 for powder mater iai
R-物料容量（吨/立方米）Density (ton / m3)
K-修正系数，一般取0.7~0.8 k-rectification coef-ficient.it is 0.7~0.8 usually
