Description

Technical Field

[0001] The present invention relates to the technical field of machine tool liquid filtration, and in particular to an integrated, consumable-free, negative pressure impurity filtering device and a treatment method for machine tool liquid. Background Art

[0002] Lathe cutting is a machining process that removes material from a workpiece through the relative motion between the rotating workpiece and the cutting tool on the lathe. The cutting process involves contact between the tool and the workpiece surface, removing excess material to create the desired size and shape. Cutting fluid is used during this process, and since it can be recycled and reused, a cutting fluid circulation and filtration device is required.

[0003] The existing Chinese invention patent with reference number CN119282810A relates to a cutting fluid filter device for a machining lathe and its working method, belonging to the field of machine tool processing technology. The fixed frame is fixed to the outer wall of the outer barrel, the inner wall of the fixed frame is slidably connected to the positioning block, the outer side of the positioning block is fixedly connected to one end of a horizontally arranged pull rod, and the other end of the pull rod slides out of the outer side of the fixed frame. A first spring is mounted on the outer side of the pull rod, one end of the first spring rests on the positioning block, and the other end rests on the corresponding inner wall of the fixed frame; the two ends of the horizontal plate are respectively fixedly connected to the upper ends of the corresponding vertically arranged positioning rods, and the lower ends of the positioning rods are respectively limitedly connected to the corresponding positioning blocks. The present invention facilitates the disassembly and assembly of the filter assembly on the horizontal plate through a disassembly and assembly mechanism, avoiding the problem of inconvenient cleaning caused by the small space in the inner barrel, and facilitating the maintenance of the scraper and magnet by the staff; in addition, the cutting fluid attached to the inner wall of the inner barrel can be scraped off by the scraper rod, avoiding the attachment of cutting fluid and impurities to the inner barrel.

[0004] The above-mentioned filtering device filters impurities in the cutting fluid through a filter. Since the filter cannot discharge impurities by itself, this method is limited by the service life of the filter and needs to be cleaned or replaced regularly. At the same time, it uses magnets to adsorb metal impurities. Since the magnitude of the magnetic force is inversely correlated with the distance between the impurities and the magnet, the greater the distance, the smaller the magnetic force on the impurities. The center of the pipeline cannot be affected by the magnetic force, and the adsorption effect is limited. At the same time, the impurities will move inside the pipeline with the magnet after the magnet moves, and the impurities will accumulate within the coverage range of the magnet's magnetic force, affecting the permeability of the pipeline, and the impurities in the pipeline cannot be discharged by themselves. Summary of the Invention

[0005] In response to the shortcomings of the existing technology, the present invention provides an integrated, consumable-free negative pressure impurity filtration device and treatment method for machine tool liquids, which solves the problems of needing to clean the filter screen regularly, the magnetic adsorption effect being limited by distance, and the impurities being unable to be discharged by themselves.

[0023] Beneficial effects

[0024] The present invention provides an integrated, consumable-free negative pressure impurity filtration device and treatment method for machine tool fluids. Compared with the prior art, it has the following advantages:

[0025] (1) The integrated non-consumable negative pressure impurity filtering equipment and treatment method for machine tool liquid drives the transmission shaft to drive the conveying auger to rotate by the transmission motor, so that the large-volume impurities inside the metal mesh move to the chip discharge pipe at the front end of the coarse filter pipe and are discharged through the chip discharge pipe. This method only performs preliminary filtration of the large-volume impurities in the liquid through the metal mesh, and adsorbs the small-volume impurities through the adsorption unit below, without filtering through the filter screen, directly eliminating the operation of cleaning the filter screen.

[0026] (2) The integrated non-consumable negative pressure impurity filtering equipment and treatment method for machine tool liquid, through the setting of the transmission pipe, after preliminary filtration, the liquid will move downward to the inside of the transmission pipe through the connecting pipe and the rotary joint, and flow downward into the inside of the receiving barrel through the diverter pipe inside the transmission pipe, and the driving motor drives the driving gear to rotate, so that the driving gear drives the transmission gear outside the transmission pipe to rotate. Since the number of teeth of the driving gear is much larger than that of the transmission gear, the transmission gear will drive the transmission pipe to rotate rapidly, and the diverter pipe is used to limit the position where the liquid enters the inside of the receiving barrel, and drives the liquid to rotate, so that before the liquid falls, a certain centrifugal force is generated, so that the liquid can maintain a certain distance from the rotation center when it contacts the transmission plate, so that it can continue to rotate under the drive of the transmission plate, and the centrifugal force is used to drive the impurities to contact the inner wall of the receiving barrel. The liquid will form a water ring in contact with the inner wall of the receiving barrel inside the receiving barrel. The wall thickness of the water ring is limited by the transmission plate, so that the distance between the liquid and the electromagnet is kept within the high magnetic force range, avoiding the distance affecting the adsorption effect of the electromagnet.

[0027] (3) The integrated non-consumable negative pressure impurity filtering equipment and treatment method for machine tool liquid, due to the adsorption of static electricity and electromagnets, small-volume impurities will remain on the inner wall of the receiving barrel. The transmission plate will drive the scraper to rotate when it rotates. The scraper can transport the impurities on the inner wall of the receiving barrel upward to the top of the receiving barrel, and move them to the annular cavity between the outside of the receiving barrel and the top cover under the guidance of the transmission ring, and discharge them through the drain pipe, thereby achieving the effect of automatic discharge of impurities.

The scraper (236) can transport the impurities on the inner wall of the receiving barrel (2384) upward to the top of the receiving barrel (2384), and move them to the annular cavity between the outside of the receiving barrel (2384) and the top cover (2381) under the guidance of the transmission ring (233), and discharge them through the sewage pipe (2383).
