Silicon carbide ceramic filtering membrane group for industrial cutting fluid regeneration

Abstract

The present invention discloses a silicon carbide ceramic filtration membrane group for industrial cutting fluid regeneration. The silicon carbide ceramic filtration membrane group comprises a filtration membrane layer, a transition layer and a support layer which are sequentially arranged from inside to outside along an overflow channel, wherein the filtration membrane layer, the transition layer and the support layer are formed by integrally sintering silicon carbide with purity of more than 99.9%. The silicon carbide ceramic filter membrane group for industrial cutting fluid regeneration, which adopts the structure, is formed by integrally sintering 99.9% of silicon carbide, the lipophilicity is reduced by utilizing the characteristics of the silicon carbide, and 99% of waste oil and scrap iron and 95% of microorganisms and bacteria in the cutting fluid can be removed.

Description

technical field [0001] The invention relates to a cutting fluid regeneration technology, in particular to a silicon carbide ceramic filter membrane group used for industrial cutting fluid regeneration. Background technique [0002] Cutting fluid is an industrial liquid used in metal cutting and grinding to cool and lubricate cutting tools and workpieces. Performance, lubrication performance, anti-rust performance, degreasing and cleaning function, anti-corrosion function, easy to dilute. It overcomes the shortcomings of traditional soap-based emulsions, which are easy to smell in summer, hard to dilute in winter, and poor anti-rust effect, and has no adverse effect on lathe paint. It is suitable for cutting and grinding of ferrous metals and is currently the most advanced grinding product. [0003] During the use of the existing cutting coolant, with the prolongation of the use time, bacteria breed, and it is easy to smell and deteriorate, so it needs to be replaced regular...

AI Technical Summary

Problems solved by technology

[0008] 3) The hardness of the filter element is not enough, it is easily scratched and damaged by the hard particles in the cutting fluid, and it needs to be replaced frequently;

[0009] 4) The setting of ceramic membrane filter pore size is unreasonable. If the pore size is too large, bacteria and suspended solids will pass through the membrane body, resulting in poor sterilization and removal of suspended solids. If the pore size is too small, the effective components in the cutting fluid will be intercepted and the regeneration of cutting fluid will be affected. Effect
