[0002] Sludge dewatering machine is a kind of continuously running sludge treatment equipment. Sludge dewatering machine is divided into: belt type sludge dewatering machine, plate and frame type sludge dewatering machine, stacked type sludge dewatering machine and centrifugal type sludge dewatering machine.

[0003] Existing centrifugal sludge dewatering machines generally use the centrifugal force generated by high-speed rotation to drive the separation of mud and water in the sludge. However, when the centrifugal sludge dewatering machine is filled with sludge, it needs to be dehydrated by high-speed rotation for a long time. After dehydration, the sludge is re-injected into the centrifugal sludge dewatering machine, which has low efficiency and cannot perform continuous sludge dehydration. Utility Model Content

[0004] The utility model aims to provide a sludge centrifugal dewatering device to solve the problems raised in the above background technology.

[0006] Preferably, a plurality of first fixing rods are longitudinally penetrated and connected to the surfaces of the plurality of stacking rings and the top plate, and the first fixing rods penetrate the top plate and the stacking rings and extend into the interior of the fixing groove.

[0007] Preferably, a protective pipe is installed at the upper end of the centrifuge, and the size of the protective pipe is larger than the size of the transmission pipe.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. This sludge centrifugal dewatering equipment transports the sludge to the inside of a fixed tank. As the sludge water level inside the fixed tank rises, the sludge will gradually pass through the area of ​​multiple superimposed rings. The multiple superimposed rings are in close contact with each other, and only water molecules can pass through. At this time, part of the water in the sludge will be discharged from the gaps between the superimposed rings. The sludge with some water discharged will enter the inside of the centrifuge through the transmission pipeline for centrifugal dehydration. The large volume of sludge is initially dehydrated through the multiple superimposed ring areas, and the water content in the sludge is mostly reduced, so that the volume of sludge entering the centrifuge is reduced, the working time of the centrifuge is reduced, and the working efficiency is increased.

[0013] 2.
