Description

Technical Field

[0001] This utility model relates to the field of cutting fluid filtration and reuse technology, and in particular to an online filtration and reuse system for grinding machine cutting fluid. Background Technology

[0002] Cutting fluid is an industrial liquid used in metal cutting and grinding processes to cool and lubricate cutting tools and workpieces. It is scientifically formulated with various high-performance additives, possessing excellent cooling, lubrication, rust prevention, degreasing, cleaning, and anti-corrosion properties, and is easily diluted. It is widely used in the machining industry, especially in CNC machining. However, due to its high cost and the need for recycling, oil and grease droplets into the cutting fluid during recycling can promote the growth of anaerobic bacteria, making the cutting fluid prone to deterioration and foul odor. This not only affects its recycling efficiency but also impacts the health of workers. To ensure successful recycling, filtration is necessary. For example, Chinese utility model patent CN215388077U discloses a simple cutting fluid circulation filtration device with a stepped design and two-stage filters. This improves the purity of the cutting fluid and increases its contact time with oxygen, thus avoiding frequent cutting fluid changes that pollute the environment and reducing the economic burden on enterprises.

[0003] The aforementioned patent still has some problems in use. The cutting fluid flows through the stepped filter box from top to bottom. The cutting fluid flows down from the top of each filter box and is prone to splashing everywhere in the process. This not only causes waste but also affects the filtration effect. In addition, the contact area between the filter screen and the cutting fluid is small, which affects the filtration efficiency of the cutting fluid. Utility Model Content
