VFD Decanter Centrifuge Differential Speed Machine 440V

Anti - corrision horizontal decanter centrifuge for dehydration

Product description

The decanter centrifuge uses the density difference between the solid and liquid phases to accelerate the sedimentation speed of the solid phase particles under the action of centrifugal force to achieve solid-liquid separation. The specific separation process is that the material is sent into the mixing chamber of the bowl through the inlet pipe. Under the action of centrifugal force, the solid particles with larger specific gravity settle to the inner wall of the drum to form a mud layer, and then the relative speed difference between the spiral and the drum is used to remove the solid phase. Push to the cone end of the rotating drum. After pushing out the liquid surface, the sludge can be dehydrated and dried, and then pushed to the slag discharge port to be discharged. The supernatant is discharged from the big end of the rotating drum to achieve solid-liquid separation.
The larger the diameter of the bowl, the longer the effective length, the larger the effective settlement area, the greater the processing capacity, and the longer the residence time of the material in the bowl. At the same speed, the greater the separation factor, the greater the separation factor. The better the effect. However, due to the limitation of materials, the diameter of the bowl of a decanter centrifuge cannot be increased indefinitely, because as the diameter increases, the maximum allowable speed will decrease with the decrease of the material's solidity, and the centrifugal force will also decrease accordingly. Usually the diameter of the bowl is between 200~1000mm, and the ratio of length to diameter is between 3~4. The development of current decanter centrifuges tends to have a high speed and large aspect ratio. This kind of equipment is more suitable for the treatment of low-concentration sludge, and the degree of sludge is better.
