[0002] Cutting fluid refers to a mixed liquid used to lubricate and cool tools and workpieces during metal cutting. It is an important working medium in mechanical processing. During grinding, a large amount of fine chips and particulate impurities are mixed in the cooled cutting fluid. In order to recycle the cutting fluid, the cutting fluid needs to be filtered and purified. Flat mesh paper belt filter is a commonly used equipment for cutting fluid purification. Its principle is to rely on the gravity of the liquid itself to pass through the filter cloth to isolate the impurities in the coolant, thereby achieving the purpose of purifying the liquid. However, when there are many impurities in the cutting fluid and the filtration accuracy is high, the filter cloth will be consumed quickly and the cost of use will increase. In addition, some grinders require a large coolant flow rate and high filtration accuracy, but the filtration device does not have enough installation space. Therefore, it is necessary to design a cutting fluid filtration device with a small footprint, large filtration flow rate and low use cost. Utility Model Content
