Oil liquid centralized treatment system and treatment method

Abstract

The invention discloses an oil liquid centralized treatment system and method. The treatment system comprises an oil liquid pumping station, a paper tape type filtering device, an oil liquid collecting box, a UV sterilization device, a three-phase separation device, a liquid purifying box, a liquid supplying device, an online monitoring device, a control system, a pipeline and an automatic liquid supplementing device. Oil liquid is filtered by the paper tape type filtering device and then enters the oil liquid collecting box, the oil liquid collecting box is communicated with the UV sterilization device through a pipeline, and microorganisms in wastewater are sterilized through UV rays; the UV sterilization device is communicated with the three-phase separation device through a pipeline, and sterilized oil enters the three-phase separation device; the three-phase separation device is communicated with the clean liquid tank through a pipeline, and the clean liquid tank is connected with the on-line monitoring device and the automatic liquid supplementing device. According to the oil liquid centralized treatment system and method, oil liquid in multiple machine tools can be treated in a centralized mode, oil liquid treatment and supply do not interfere with each other, normal operation of the machine tools is not affected, and the oil liquid treatment efficiency is improved.

Description

technical field [0001] The invention relates to the field of oil treatment, in particular to a centralized oil treatment system and a treatment method. Background technique [0002] The role of water-based metalworking fluid emulsion is mainly to cool, lubricate, prevent rust, and clean, so as to ensure precise machining accuracy, good workpiece surface roughness, flush iron filings, and prolong tool life. The following problems will occur during the use of the emulsion: the emulsified oil contains fatty oil and unsaturated fatty acids, which are easily corroded by microorganisms, decomposed and destroy the balance of the emulsion, resulting in oil precipitation and increased acid value, which may appear: corruption Odor is produced; the emulsion changes from milky white to taupe; the pH value and anti-rust function drop sharply; the oil and water of the emulsion separate and generate sediment or sludge, and the cutting performance decreases. Moreover, during use, miscellan...

AI Technical Summary

Problems solved by technology

The following problems will occur during the use of the emulsion: the emulsified oil contains fatty oil and unsaturated fatty acids, which are easily corroded by microorganisms, decomposed and destroy the balance of the emulsion, resulting in oil precipitation and increased acid value, which may appear: corruption Odor is produced; the emulsion changes from milky white to taupe; the pH value and anti-rust function drop sharply; the oil and water of the emulsion separate and form sediment or sludge, and the cutting performance decreases

In addition, in hard water containing various minerals and salts, the emulsion process is often hindered, the emulsion is separated rapidly, and a large amount of water-insoluble soap is precipitated, thereby shortening the service life

In the prior art, the emulsion preparation and concentration detection are usually measured manually, and the manual measurement of the concentration has a large error

During use, the concentration of the emulsion will change, which is difficult to control
