Slurry separation system

Abstract

A slurry separation system comprises a feeding device, a cyclone desanding device, a flocculation precipitation device and a spiral separation device, wherein the spiral separation device comprises aslurry inlet pipe, an outer shell, a conical screw, a filter sleeve, a gear motor, a slurry outlet and a water outlet; a feeding pipe at the bottom of the feeding barrel is connected to a slurry inletpipe, and the slurry inlet pipe is connected with a cyclone desander; the slurry outlet pipe is connected with the sedimentation tank; an inclination angle of 30-40 degrees is formed between the outer shell and the ground; the filter sleeve is fixedly arranged in the middle bin; the conical screw is arranged in the filter sleeve and penetrates out of the middle bin, and an input shaft of the conical screw is connected with the gear motor; flocculated slurry is conveyed to the slurry inlet bin through the slurry inlet pipe and extruded by the first spiral blade and the second spiral blade of the conical screw to be drained, moisture of the flocculated slurry is drained to the middle bin through the filter sleeve and then drained through the water outlet, and slurry blocks generated throughrotary extrusion are drained from the end of the conical screw, enter the slurry outlet bin and then are drained through the slurry outlet. The slurry separation efficiency is improved, the slurry water content is reduced, and the slurry treatment cost is saved.

Description

technical field [0001] The invention relates to the technical field of mud filtration treatment, in particular to a mud separation system. Background technique [0002] With the continuous enhancement of my country's economic strength, my country's infrastructure investment and real estate investment have grown rapidly. Huge investment has played a key role in the rapid development of the construction industry. Bored cast-in-situ piles are widely used in the foundation construction of a large number of deep foundations and foundation treatment. Bored cast-in-situ piles generally use mud protection technology in the construction process. The static pressure of the mud on the groove wall and the mud skin formed by the mud on the groove wall can effectively prevent the groove and hole walls from collapsing, thereby easily meeting the requirements of piling. But, generally all will use mud to assist drilling construction in the construction process of bored cast-in-situ pile a...

AI Technical Summary

Problems solved by technology

However, since mud is generally used to assist drilling construction in the construction process of bored piles at present, a large amount of waste mud to be processed must be produced on the site after the pile is formed.

The existing technology generally adopts the method of centralized storage and treatment of waste mud on site. Because the waste mud has a large consistency, it is difficult to sink naturally and cannot be discharged directly, resulting in a large area of ​​mud pools occupying valuable construction sites, which not only affects the construction progress and
