Centrifugal mud dehydrator and dehydration treatment method

Abstract

The invention relates to a centrifugal mud dehydrator and a dehydration treatment method. The dehydrator comprises a supporting base, a first bearing disc, a second bearing disc, a centrifugal barrel,a spiral feeding rod, a motor frame, a driving motor, a transmission belt and a feeding pipe, wherein a rectangular groove is formed in the top of the supporting base, the first bearing disc is arranged at one end of the interior of the rectangular groove, the second supporting disc is arranged at the other end of the interior of the rectangular groove, the centrifugal barrel is located between the first supporting disc and the second supporting disc, the two ends of the centrifugal barrel are fixed to the side wall of the first supporting disc and the side wall of the second supporting discin a welded mode, the spiral feeding rod is arranged in the center of the interior of the centrifugal barrel, one end of the spiral feeding rod is arranged at the interior of the first bearing disc, the other end of the spiral feeding rod is arranged on the second bearing disc, and the center of the other end of the second bearing disc is connected with the feeding pipe. The dehydrator has the characteristic of automatically cleaning filter holes, and is more sufficient in mud separation compared with a traditional separation machine.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a centrifugal mud dehydrator and a dehydration treatment method. Background technique [0002] Slurry concentration mainly refers to the use of gravity to effectively increase the solid content of the mud. If the gravity concentration tank is used to treat the sewage, it will take a lot of time, and the organic matter in the sewage will be corrupted and smelly due to the action of microorganisms. Seriously affect the sanitation of sewage treatment plants. Therefore, in the actual treatment process, after using the gravity concentration tank to reduce the water content of the sludge to 94% to 96%, it is necessary to use the sludge dehydration equipment to reduce the water content of the sludge to below 80%, so as to facilitate the later stage. Transport and disposal work. The current common sludge dewatering equipment includes belt filter press dewatering machine, centr...

AI Technical Summary

Problems solved by technology

[0003] However, the centrifugal mud dewatering machines currently on the market have the following problems during use, a. Because the sludge particles in the mud are thrown out at high speed during the use of the traditional centrifugal mud dewatering machines, some sludge particles will adhere Around the filter hole, the effect radius of the filter hole is reduced, which affects the separation efficiency in the mud water. In severe cases, the filter hole will be blocked, resulting in the separation process cannot be performed normally; b. The existing centrifugal mud dewatering machines all use Placed horizontally, so that after the separation of the mud, part of the water in the mud remains in the centrifugal cylinder, resulting in insufficient separation of the mud
