Metal grinding fluid precision filtration system and method

Abstract

A metal grinding fluid precision filtration system is used for filtering a metal grinding fluid, the metal grinding fluid precision filtration system includes a water tank, a magnetic filter, a waterpump, a first precision filter, a second precision filter, a third precision filter and a filter pipe, the water tank, the magnetic filter, the water pump, the first precision filter, the second precision filter and the third precision filter are sequentially connected in series by the filter pipe, the filtering precision of the second precision filter and the filtering precision of the third precision filter are greater than that of the first precision filter, and the filtering precision of the first precision filter is greater than or equal to 1um m. The metal grinding fluid precision filtration system adopts the physical filtration, the filtered metal grinding fluid may not change in chemical properties, the service life of the metal grinding fluid is prolonged, enterprise cost is reduced, emission is reduced, and the filtered metal grinding fluid is beneficial to the environment. The invention also relates to a metal grinding fluid precision filtration method.

Description

technical field [0001] The invention relates to the technical field of metal grinding fluid regeneration manufacturing, in particular to a metal grinding fluid precision filtration system and a method thereof. Background technique [0002] Metal grinding fluid has good cleaning and penetrating performance, which can prevent the passivation of tools and abrasives, has a good self-sharpening effect on abrasives, improves the cutting force of tools, prolongs the service life of tools, and shortens the processing time of a single workpiece. Moreover, the metal grinding fluid also has outstanding lubricating properties, which can significantly reduce the noise generated when cutting workpieces, avoid sparks when processing workpieces, reduce the occurrence of grinding scratches, significantly improve the surface quality of processed workpieces, and greatly improve the smoothness of workpieces. . In addition, it can effectively inhibit the corrosive hazards of various factors on ...

Problems solved by technology

[0003] However, due to the long-term use of the metal grinding fluid, more and more impurities will be deposited, and the impurities include metal powder, colloidal suspension, sand and stone, etc. Due to the increase in impurities, the use effect and performance of the metal grinding fluid will be reduced. A sharp decline

In the traditional metal grinding fluid filtration method, the filtration accuracy is mostly tens of microns to several millimeters, and the traditional filtration method needs to use a large number of consumables, and the use cost is high

When the metal grinding fluid is recycled for a long time, the particle size of the deposited tiny impurities may be less than one micron, and the traditional filtration method has no way to filter the tiny impurities, so these metal grinding fluids can only be recycled and discharged.

The metal grinding fluid is not only expensive, but also has a high cost of use and will pollute the environment.
