Description

Mud cake dispersing device

Technical Field

The utility model belongs to the field of sludge treatment equipment, and particularly relates to a mud cake dispersing device.

Background

In the sludge recovery treatment process, the redundant water in the sludge is discharged by utilizing equipment such as plate frame mud pressing and the like, so that the sludge forms relatively dry mud cakes, and then the mud cakes are scattered by utilizing a scattering device. The existing scattering device mainly adopts a rotating impeller to scatter mud cakes, when the device is used, the mud cakes are put into the device from the upper part, the mud cakes are scattered by the impeller in the falling process, and the structure needs the impeller to rotate at a high speed to avoid the mud cakes from falling from the interval between the blades, so that the scattering non-uniformity is caused, and the scattering effect is influenced; if the rotating speed of the impeller is increased, although mud cakes can be scattered more uniformly, the impeller rotating at a high speed easily causes the mud to be sputtered everywhere, so that the production environment is affected and the equipment is accumulated; on the other hand, the mud cake can generate larger impact on the blade in the falling process, and the blade is easy to deform.
