Description

Technical Field

[0001] The utility model relates to the technical field of industrial wastewater, in particular to an industrial wastewater self-cleaning filter. Background Art

[0002] Industrial wastewater includes production wastewater, sewage, and cooling water. Cutting fluid, a type of cooling water, is an industrial liquid used to cool and lubricate cutting tools and workpieces during metal cutting, grinding, and polishing processes. Made from a scientifically formulated blend of multiple highly functional additives, cutting fluid offers excellent cooling, lubrication, rust prevention, oil removal, cleaning, corrosion protection, and easy dilution. It overcomes the shortcomings of traditional soap-based emulsions, such as summer odor, difficulty in dilution, and poor rust prevention. It also has no adverse effects on lathe finishes. Suitable for the cutting and grinding of ferrous metals, it is currently the most advanced grinding product. Cutting fluid outperforms saponified oil in all aspects, offering excellent cooling, cleaning, and rust prevention properties. It is also non-toxic, odorless, non-corrosive to humans, equipment, and the environment. Although cutting fluid can contain iron filings after use and cannot be reused, filtering can remove these iron filings, allowing for reuse and cost savings.

[0003] Existing equipment for filtering cutting fluid generally uses filter cotton. Iron chips in the cutting fluid will enter the filter cotton, which is difficult to clean.
