Grinding fluid automatic circulation and physicochemical precipitation filter press purification device for centerless grinder

Abstract

The invention discloses a grinding fluid automatic circulation and physicochemical precipitation pressure filtration purification device for a centerless grinder. Including slag-containing wastewater collection tank, clean circulating fluid collection tank, agitated four-partition integrated precipitator, submersible mixer, mortar pump and centrifugal filter press; the waste water submerged pump in the slag-containing wastewater collection tank pumps slag-containing circulating fluid pumped into the agitated four-division integrated precipitator; the cleaning circulating fluid in the upper floating layer of the agitated four-divided integrated precipitator overflows to the clean circulating fluid collection tank through the overflow pipe; the mortar pump transfers the agitated four-divided The slag-containing circulating fluid in the mixed layer in the middle of the integrated precipitator is pumped into the centrifugal filter press. The invention satisfies the technical requirements of large amount of grinding debris and high cleanliness of the grinding fluid during the grinding process of the centerless grinding equipment, prolongs the service life of the grinding fluid, reduces the frequency of replacement, reduces the amount of addition, and improves the grinding quality of the workpiece. Significantly improve the overall efficiency of the equipment.

Description

technical field [0001] The invention relates to the technical field of ultra-long piston rod grinding, in particular to a grinding fluid automatic circulation and physicochemical sedimentation filter press purification device for a centerless grinder. Background technique [0002] Centerless grinder is a typical equipment suitable for grinding super-long piston rods. It has high processing efficiency and is suitable for processing batch products. Due to the large grinding allowance in the grinding process, the process characteristics of high calorific value and high slag content are caused. , It is easy to produce defects such as workpiece deformation during the grinding process, burns and scratches on the grinding surface, which puts extremely high requirements on the circulation and purification capabilities of the grinding fluid system. [0003] The conventionally used grinding fluid circulation purification system is a combination of magnetic separation filtration and fi...

AI Technical Summary

Problems solved by technology

[0004] 1. The separation and filtration of waste slag is not clean, the cleanliness of the grinding fluid cannot meet the grinding process, the workpiece is scratched during the grinding process, the consumption of filter paper is large, the grinding fluid is carried out and lost, the moisture content of the waste slag is high, and there are problems such as environmental hazards ;

[0005] 2. Manual operation is required to clean up grinding debris and replace filter paper, and the overall efficiency of equipment operation is low
