The unadjustable factors affecting the use effect of horizontal screw centrifuge

There are many factors affecting the use effect of horizontal screw centrifuge, generally summarized as adjustable factors and non adjustable factors brought by the mechanical part Last time we introduced adjustable factors, this time I will introduce to you what are the non adjustable factors affecting horizontal screw centrifuge First of all, the diameter and effective length of the drum The larger the drum diameter is, the longer the diameter length is, the larger the effective settlement area is, and the larger the processing capacity is Then, the longer the material stops running in the drum At the same speed, the larger the separation factor is, the better the separation effect is The centrifugal opportunity is limited by the material, and its drum diameter is impossible to increase without limitation If the diameter increases, the allowable speed will decrease with the decrease of material firmness, and the centrifuge will also decrease with it In the case of the same processing capacity, generally large drum diameter centrifuges run at a lower differential speed, small drum must improve the differential speed Second, the drum half cone angle The half cone angle of the drum is more important in the design of the centrifuge In terms of the clarification effect, the cone angle should be as large as possible In terms of the slag conveying and dehydration effect, the cone angle should be as small as possible However, the slag conveying is the necessary condition for the normal operation of the centrifuge, so the slag conveying condition should be satisfied first in the design The half cone angle of the hard to separate material is generally within 6 degrees, and that of the common material is within 10 degrees After Zui, it is the type of pitch and screw The pitch directly affects the success or failure of slag transportation For materials that are difficult to separate, it is difficult to transport slag The pitch should be smaller For materials that are easy to separate, the pitch should be larger, so as to improve the transportation capacity of sediment The type of helix is also very important The function of helix is to transport the sediment settled in the inner side of the drum and to discharge the slag smoothly It is not only a discharge device, but also determines the production capacity, separation effect and service life.
