A centrifugal separation device for river sludge treatment process

Abstract

The invention discloses a centrifugal separation device for river sludge treatment process, which comprises a casing, a mud inlet pipe, a fixing seat and a rotating drum, one end of the casing is a first tapered part, and the two ends of the casing are connected to The fixed seat is fixed by welding, and a drum is movably connected between the two fixed seats through bearings, and one end of the drum is connected to the external torque, and the drum is a hollow structure, and one end of the drum is a second tapered The first tapered part and the second tapered part are arranged in the same vertical plane, and a mud inlet pipe is arranged inside the drum, and a differential clutch is connected between the mud inlet pipe and one end of the drum , a rectifying cone is installed at one end of the second tapered part, and a scraper is evenly arranged on the outside of the rectifying cone, and the rotating outer diameter of the scraper is equal to the inner diameter of the mud inlet pipe, and the rectifying cone is attached to the second cone The side wall of the shape part, according to the present invention, has the characteristics of easy cleaning and removal of internal dirt.

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...

Problems solved by technology

[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 deposited on the inner wall of the drum of the centrifugal separation device. Because there is a mud screw inside, the shell needs to be opened for cleaning, or there are multiple one-way spray holes built into the inner wall, which will damage the device. Wholeness
