Description

technical field

[0001] The invention relates to the technical field of sludge treatment, in particular to a centrifugal separation device used in a river sludge treatment process. Background technique

[0002] The sludge in the refinery sewage treatment plant is composed of oil sludge, scum and residual activated sludge, which is usually called "three sludges". Sludge includes dirty oil. The centrifugal dehydrator is a traditional sludge treatment equipment that uses the centrifugal force generated by the high-speed rotation of the drum for solid-liquid separation.

[0003] In the existing sludge centrifugal separation device, because the sludge is fed slowly through the external thrust, a large amount of sludge is easily deposited on the pipe wall during the contact and friction process between the mud and the pipe wall. When cleaning, it needs to be manually scraped into the mud inlet pipe. The cleaning method is very troublesome; at the same time, dirt will also be depo...
