Technical Field

[0001] The utility model relates to the technical field of metal cutting fluid recycling equipment, in particular to a metal cutting fluid filtering device. Background Art

[0002] Cutting fluid, sometimes also called cutting oil, cutting fluid, coolant or lubricant, is a special liquid used to cool and lubricate the workpiece and tool during machining. Cutting fluid may be oil, oil-water emulsion, paste, gel, aerosol, air, petroleum distillate, animal fat, vegetable oil, water or other materials. Most metals can benefit from the use of cutting fluid during machining.

When in use, the sliding block is pulled forward to expose the positioning slot, and a magnet block is installed in the positioning slot. When the metal cutting fluid falls on the filter net, the filter net filters and intercepts metal debris. When the metal cutting fluid falls from the filter net into the water tank, the magnet block absorbs the fine metal debris in the metal cutting fluid. A small filter is placed in the second threaded slot, and then the discharge pipe is connected to the fixed pipe, and the fixed pipe is connected to the connecting pipe. The metal cutting fluid flows into the connecting pipe through the connecting slot and flows from the connecting pipe into the fixed pipe. The small filter in the fixed pipe filters the metal cutting fluid again, and finally it is collected manually.
