They are generally divided into metal cutting machine tools, forging machine tools, and woodworking machine tools. During the processing of iron parts, various machine tools used in machining workshops will generate a large amount of iron filings, which will remain in the machining coolant. During the operation of machine tools, a large amount of dust, solid particle pollutants and other debris will be mixed into the coolant.

[0034] The following is a detailed description of the working principle of the CNC machine tool coolant filter device.

[0035] like Figure 1-6 As shown, first, when the coolant flows into the interior of the filter cartridge assembly 23 through the scraping device 3, the filter cartridge assembly 23 is driven to rotate by the output shaft of the motor 21, so that the filter cartridge assembly 23 uses the fixed ring 225 to squeeze the elastic roller 224, so that the elastic roller 224 squeezes the movable frame 222, so that the movable frame 222 squeezes the interior of the pressure-resistant casing 4 through the rotating wheel 223, so that the filter cartridge assembly 23 is supported inside the pressure-resistant casing 4, and the friction of the filter cartridge assembly 23 when rotating inside the pressure-resistant casing 4 is reduced by the rotation of the rotating wheel 223. 3.

When the filter screen tube 231 rotates, impurities and coolant are separated. When the filter screen tube 231 rotates at a faster speed, the iron block 263 moves by means of the slide bar 262 due to the centrifugal force, so that the iron block 263 pulls the elastic frame 266 to move, and separates and moves through the extrusion rod 1 264 and the extrusion rod 265, and pulls the rotating rod 233 through the rotating rod 232 through the bidirectional rotating shaft 235, so that the impurities on the surface of the rotating rod 233 fall to the bottom, so that the impurities and coolant are quickly separated, and the impurities are prevented from falling too fast, causing the coolant to fall into the collection box 25 together, affecting The filtering effect is that when impurities and coolant fall onto the inner wall of the water inlet pipe 31, the impurities and coolant stick to the inner wall of the water inlet pipe 31, and the turntable 33 is driven to rotate by the output shaft of the motor 2 32, so that the turntable 33 drives the moving rod 34 to rotate, and the inner wall of the water inlet pipe 31 is scraped off by the moving rod 34 to scrape off the sticky impurities, and the moving rod 34 moves toward the inside of the turntable 33, and the moving rod 34 is squeezed by the elastic force of the elastic roller 2 35, so that the moving rod 34 tightly scrapes the inside of the water inlet pipe 31 to prevent impurities from sticking to the inner wall of the water inlet pipe 31 and affecting the filtering of the device.

[0036] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
