Sewage treatment desliming machine

Abstract

The invention discloses a sewage treatment desliming machine. The machine comprises a centrifugal pipeline and a machine shell used for internally arranging the centrifugal pipeline, the centrifugal pipeline comprises an inner pipeline and an outer pipeline, the inner pipeline is of a sandglass-shaped structure with two large ends and a small middle, and a first water inlet pipeline and a second water inlet pipeline which are communicated with the inner pipeline are coaxially installed at the two ends of the inner pipeline respectively; and the machine shell comprises two independent sub-binswhich are arranged in a spaced mode and are symmetrical left and right, the sub-bins respectively surround two parts of pipe sections, except the transition section, of the outer pipeline to make theportions, towards the two ends, of the outer pipeline inserted into the sub-bins respectively with the transition section of the outer pipeline as the boundary, and are in clearance fit with insertingholes of the sub-bins, the outer walls of the two pipe sections are coaxially sleeved with spiral blades respectively, and the spiral directions of the two spiral blades are opposite. The inner pipeline and the outer pipeline are driven by a transmission system to rotate in the same direction at differential speed, and the rotating speed of the outer pipeline is higher than that of the inner pipeline. The desliming machine is good in desliming effect.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a sewage treatment deslimer. Background technique [0002] Deslimers are widely used in sewage treatment projects. There are many existing deslimers, the most common of which is the centrifugal deslimer. When the centrifuge rotates at a high speed, it generates a large centrifugal force and strengthens the gravity separation process. , so that the fine ore particles can be recovered more effectively, and the full recovery of the fine particles has been successfully solved. Therefore, it is widely used in the recovery of tungsten, tin, iron and other ore sludge in industrial or engineering sewage. The current structure of this type of desilter is mainly a tubular body full of pores as a centrifugal pipeline. After the sewage enters, the pipeline rotates, and the sludge is thrown out of the pores into the outer shell, where it accumulates. Discharge after precipitation to...
