Description

A central effluent filtration system and method for machine tool cutting fluid treatment Technical Field

[0001] This invention relates to the field of cutting fluid treatment technology, specifically to a central outlet water filtration system and method for machine tool cutting fluid treatment. Background Technology

[0002] Cutting fluid is an industrial liquid used in metal cutting, machining, and grinding processes to cool and lubricate cutting tools and workpieces. Cutting fluid is often used as an auxiliary agent in machine tool processing, resulting in the presence of metal chips in the fluid. When treating cutting fluid, these metal chips usually need to be filtered out. Common methods include magnetic filtration, mechanical filtration, and centrifugal filtration. Magnetic filtration utilizes the property of magnetic attraction to metal chips, using a magnetic filter to adsorb and separate them from the cutting fluid. It avoids the limitations of mechanical filtration (limited by the size of the filter mesh) and centrifugal filtration (poor separation of smaller particles). However, magnetic filtration is mostly applicable only when the metal chips are magnetic, limiting its application. Since the type of metal processed by machine tools is uncertain, separating metal chips from the cutting fluid often requires two or more filtration methods working together, increasing equipment costs.

[0003] For example, a Chinese patent discloses a filtration device for separating metal chips from cutting fluid, publication number CN219308112U. This application has the problem that the filtration of metal chips is limited by the mesh size. For example, a metal filter that can automatically feed materials and separate them by magnetic force, publication number CN206793896U, has the problem that when using magnetic force to separate metals, it can only be applied when the metal being separated is a magnetic metal, thus limiting its scope of application.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Please refer to Figures 1-10. The present invention provides the following technical solutions:

[0042] Example 1: A central outlet water filtration system for machine tool cutting fluid treatment includes an inlet pipe 1, a filter box 11 for filtering metal chips, and an electromagnet 61. The filter box 11 contains a filter assembly, which includes: a battery 21, a wire 22, an insulating housing 24, a hook 25, and a magnetized bowl 26. The bottom of the battery 21 is fixedly mounted on the side wall of the filter box 11 via the outer casing 2 to energize the coil 23. The two ends of the wire 22 are electrically connected to the battery 21 and the coil 23 respectively for conducting electricity. The insulating housing 24 slides... The movable sleeve is installed outside the coil 23 to provide insulation protection for the coil 23 after it is energized. The inner ring of the hook 25 is slidably sleeved outside the insulating shell 24 to provide support for the insulating shell 24. One end of the hook 25 is hung on the edge of the magnetizing bowl 26. The magnetizing bowl 26 is set outside the insulating shell 24 and directly below the water inlet pipe 1 to receive the cutting fluid containing metal shavings. The bottom of the magnetizing bowl 26 has a water outlet, and a stop block 3 is slidably abutted against the water outlet. The stop block 3 is made of rubber material, and a fixing rod 3 is fixedly installed at the bottom of the stop block 3. 1. A support plate 5 is slidably connected to the side wall of the fixing rod 31. One end of the fixing rod 31 passes through the support plate 5. One end of the support plate 5 is fixedly installed on the inner surface of the filter box 11. A support rod 27 is fixedly installed on the side wall of the magnetized bowl 26. A T-shaped groove is opened at one end of the support rod 27. A T-shaped block 28 is slidably installed in the T-shaped groove. A spring 29 is fixedly installed on the side wall of the T-shaped block 28. One end of the spring 29 is fixedly installed inside the fixing block 210. The side wall of the T-shaped block 28 is slidably installed inside the fixing block 210. One end of the fixing block 210 is fixedly installed on the filter box 11. The support rod 27 is fixed at the fixing block 210 by one end of the T-shaped block 28 being inserted into the T-shaped groove and the other end being inserted into the fixing block 210. When disassembling, it is only necessary to move the T-shaped block 28 to one side of the fixing block 210. A fixing ring 63 is slidably sleeved on the outer wall of the support rod 27. A steel wire 62 is fixedly connected to the bottom of the fixing ring 63. One end of the steel wire 62 is fixedly installed on the side wall of the electromagnet 61. The electromagnet 61 is electrically connected to the battery 21 through the wire 6.

[0043] In use, the cutting fluid to be filtered is transported to the filter box 11 through the water inlet pipe 1. The cutting fluid containing metal fragments enters the magnetization bowl 26 for temporary storage. The filter box 11 provides support to the outer casing 2, which in turn provides support to the battery 21. The battery 21 supplies power to the coil 23 through the wire 22, causing the coil 23 to generate a magnetic field. This magnetic field magnetizes the metal fragments in the magnetization bowl 26, causing the atoms and electrons inside the metal to rearrange and thus generate magnetism. The coil 23 is protected by the insulating shell 24, and the insulating shell 24 is supported by the hook 25. The magnetization bowl 26 provides support to the hook 25, allowing the insulating shell 24 to be suspended inside the magnetization bowl 26. The support rod 27 provides support to the magnetization bowl 26, and the spring 29 provides elasticity to the T-block 28, allowing the T-block 28 to pop out from the fixing block 210 and engage with the support rod 27. This allows the fixing block 210 to provide support to the support rod 27. The support plate 5 guides and limits the fixing rod 31, which in turn provides support to the stop block 3. The stop block 3 blocks the bottom of the magnetized bowl 26, allowing the cutting fluid to temporarily remain inside the magnetized bowl 26. After the metal debris inside the magnetized bowl 26 is magnetized, the fixing rod 31 moves the stop block 3 downward under the action of external force, causing the cutting fluid and metal debris inside the magnetized bowl 26 to exit from the magnetized bowl. The molten metal flows out from inside the filter box 11 and is dispersed downwards by the arc-shaped baffle 3. The support rod 27 provides support to the fixing ring 63, the fixing ring 63 provides support to the steel wire 62, and the steel wire 62 provides support to the electromagnet 61. The battery 21 powers the electromagnet 61 through the wire 6, so that the metal debris flowing out with the molten metal is attracted by the electromagnet 61 below, thereby removing the metal debris from the molten metal. The molten metal that has been screened and filtered is discharged from the drain pipe at the bottom of the filter box 11.

[0044] Example 2: A central outlet water filtration system for machine tool cutting fluid treatment includes an inlet pipe 1, a filter box 11 for filtering metal chips, and an electromagnet 61. The filter box 11 contains a filter assembly, which includes a battery 21, a wire 22, an insulating housing 24, a hook 25, and a magnetized bowl 26. The bottom of the battery 21 is fixedly mounted on the side wall of the filter box 11 via the outer casing 2 to energize the coil 23. The two ends of the wire 22 are electrically connected to the battery 21 and the coil 23 respectively for conducting electricity. The insulating housing 24 slides... The movable sleeve is installed outside the coil 23 to provide insulation protection for the coil 23 after it is energized. The inner ring of the hook 25 is slidably sleeved outside the insulating shell 24 to provide support for the insulating shell 24. One end of the hook 25 is hung on the edge of the magnetizing bowl 26. The magnetizing bowl 26 is set outside the insulating shell 24 and directly below the water inlet pipe 1 to receive the cutting fluid containing metal shavings. The bottom of the magnetizing bowl 26 has a water outlet, and a stop block 3 is slidably abutted against the water outlet. The stop block 3 is made of rubber material, and a fixing rod 3 is fixedly installed at the bottom of the stop block 3. 1. A support plate 5 is slidably connected to the side wall of the fixing rod 31. One end of the fixing rod 31 passes through the support plate 5. One end of the support plate 5 is fixedly installed on the inner surface of the filter box 11. A support rod 27 is fixedly installed on the side wall of the magnetized bowl 26. A T-shaped groove is opened at one end of the support rod 27. A T-shaped block 28 is slidably installed in the T-shaped groove. A spring 29 is fixedly installed on the side wall of the T-shaped block 28. One end of the spring 29 is fixedly installed inside the fixing block 210. The side wall of the T-shaped block 28 is slidably installed inside the fixing block 210. One end of the fixing block 210 is fixedly installed on the filter box 11. The support rod 27 is fixed at the fixing block 210 by one end of the T-shaped block 28 being inserted into the T-shaped groove and the other end being inserted into the fixing block 210. When disassembling, it is only necessary to move the T-shaped block 28 to one side of the fixing block 210. A fixing ring 63 is slidably sleeved on the outer wall of the support rod 27. A steel wire 62 is fixedly connected to the bottom of the fixing ring 63. One end of the steel wire 62 is fixedly installed on the side wall of the electromagnet 61. The electromagnet 61 is electrically connected to the battery 21 through the wire 6.

[0045] The cutting fluid to be filtered is transported to the filter box 11 through the water inlet pipe 1. The cutting fluid containing metal fragments enters the magnetization bowl 26 for temporary storage. The filter box 11 provides support to the outer casing 2, which in turn provides support to the battery 21. The battery 21 supplies power to the coil 23 through the wire 22, causing the coil 23 to generate a magnetic field. This magnetic field magnetizes the metal fragments in the magnetization bowl 26, causing the atoms and electrons inside the metal to rearrange and thus generate magnetism. The coil 23 is protected by the insulating shell 24, and the insulating shell 24 is supported by the hook 25. The magnetization bowl 26 provides support to the hook 25, allowing the insulating shell 24 to be suspended inside the magnetization bowl 26. The support rod 27 provides support to the magnetization bowl 26, and the spring 29 provides elastic force to the T-block 28, allowing the T-block 28 to pop out from the fixing block 210 and engage with the support rod 27, thus enabling the fixing block 210 to provide support to the support rod 27. This keeps the magnetized bowl 26 in the position shown in Figure 2. The support plate 5 guides and limits the fixing rod 31, which provides support to the stop block 3. The stop block 3 blocks the bottom of the magnetized bowl 26, allowing the cutting fluid to temporarily remain inside the magnetized bowl 26. After the magnetization of the metal debris inside the magnetized bowl 26 is complete, the fixing rod 31 moves the stop block 3 downward under the action of external force, causing the cutting fluid and metal debris inside the magnetized bowl 26 to exit from the magnetized bowl 26. The fluid flows out from inside the filter box 11 and is dispersed downwards by the arc-shaped baffle 3. The support rod 27 provides support to the fixing ring 63, the fixing ring 63 provides support to the steel wire 62, the steel wire 62 provides support to the electromagnet 61, and the battery 21 energizes the electromagnet 61 through the wire 6. This causes the metal debris flowing out with the cutting fluid to be attracted by the electromagnet 61 below, thereby removing the metal debris from the cutting fluid. The filtered cutting fluid is discharged from the drain pipe at the bottom of the filter box 11.

[0046] Below the water inlet pipe 1, there are two baffles 42. The ends of the two baffles 42 that are close to each other are stepped. An arc-shaped sealing ring 43 is fixedly installed on the outer surface of each baffle 42, forming a circle. A movable rod 41 is fixedly installed on the side wall of each baffle 42. A sliding block 4 is fixedly installed at one end of each movable rod 41. The side wall of the movable rod 41 is hinged to a support frame 44 by a worm spring. One end of the support frame 44 is fixedly installed on the top of a support plate 5. The top of the support plate 5 is triangular. A pressing block 302 is slidably connected to the side wall of the sliding block 4. The pressing block 302 is inclined at the end near the sliding block 4. A second spring 301 is fixedly installed at one end of the pressing block 302. One end of the second spring 301 is fixedly installed inside the sliding rod 36. The pressing block 302 is slidably installed inside the sliding rod 36, thus causing the sliding rod 36 to be squeezed downwards. During the sliding block 4 process, the pressing block 302 can extend and retract without getting stuck at the movable rod 41. A positioning rod 35 is fixedly installed on the side wall of the sliding rod 36, and a connecting rod 37 is fixedly installed on the other side wall of the sliding rod 36. A rack 38 is fixedly installed at one end of the connecting rod 37, and a gear 39 meshes on the rack 38. A rotating rod 310 is fixedly installed on the gear 39. One end of the rotating rod 310 is fixedly installed on the output end of the servo motor 311 through a coupling. The servo motor 311 is fixedly installed on the filter box 11 through the motor box. The end of the positioning rod 35 away from the sliding rod 36 is hinged to a connecting plate 32 through a hinge. A rotating shaft 33 is hinged to the connecting plate 32 through a torsion spring. The two ends of the rotating shaft 33 are hinged to the side wall of the fixed frame 34 through worm springs. One end of the fixed frame 34 is fixedly installed on the bottom of the support plate 5. The end of the connecting plate 32 away from the positioning rod 35 is hinged to the side wall of the fixed rod 31 through a hinge.

[0047] The support plate 5 provides support to the support frame 44 and guides and limits the positioning rod 35. The servo motor 311 is started intermittently, which intermittently drives the rotating rod 310 to rotate. The rotating rod 310 intermittently drives the gear 39 to rotate, which intermittently drives the rack 38 to move upward. The rack 38 intermittently drives the connecting rod 37 to move upward, and the connecting rod 37 intermittently drives the sliding rod 36 to move upward, so that the sliding rod 36 no longer applies force to the sliding block 4. The sliding block 4 can be reset to the state shown in Figure 7 under the combined action of the movable rod 41 and the worm spring. At the same time as the movable rod 41 resets, it drives the two baffles 42 to flip, so that the two baffles 42 are combined together, and the sealing ring 43 seals the baffles 42 and the water inlet pipe 1. When the seal is closed, the cutting fluid no longer flows into the magnetized bowl 26. As the sliding rod 36 moves upward, it will simultaneously drive the positioning rod 35 to move upward. The positioning rod 35 drives the connecting plate 32 to move, and the rotating shaft 33 provides support to the connecting plate 32. The fixed frame 34 provides support to the rotating shaft 33. The connecting plate 32 can rotate around the rotating shaft 33 under the action of external force. The connecting plate 32 drives the fixed rod 31 to move, so that the fixed rod 31 drives the stop block 3 to move away from the magnetized bowl 26. At this time, the cutting fluid mixed with magnetized metal fragments in the magnetized bowl 26 can flow out. Then, the servo motor 311 drives the rotating rod 310 to rotate in the opposite direction, so that the baffle 42 opens and the stop block 3 abuts against the bottom of the magnetized bowl 26 again to start the next round of magnetization.

[0048] This invention also provides a filtration method for a central outlet water filtration system suitable for machine tool cutting fluid treatment, comprising the following steps:

[0049] S1. The cutting fluid containing metal shavings is transported to the filter box 11 through the water inlet pipe 1;

[0050] S2. The cutting fluid is temporarily stored in the magnetized bowl 26 inside the filter box 11.
