Details
pitch
Pitch, the distance between two adjacent spiral blades, is a very important structural parameter, which directly affects the success or failure of slag transport. When the screw diameter is constant, the greater the pitch and the higher the spiral rise Angle, the greater the chance of material clogging between the spiral blades. At the same time, the large pitch will reduce the number of turns of the spiral blade, resulting in uneven material distribution at the cone end of the drum, resulting in increased vibration of the machine. Therefore, for difficult to separate materials such as activated sludge, slag transport is more difficult, the pitch should be small, generally 1/5 ~ 1/6 diameter of drum, in order to facilitate transportation. For easy separation of materials, pitch should be larger, generally for drum diameter 1/2 ~ 1/5, in order to improve the transport capacity of sediment.
Screw type
The screw is the main component of centrifugal sludge dewaterer. Its function is to transport the sediment settling inside the drum and smoothly discharge the sediment. It is not only a unloading device, but also determines the production capacity, service life and separation effect.
