Description

Technical Field

[0001] This utility model relates to the technical field of coolant filtration devices, specifically a machine tool coolant filtration device. Background Technology

[0002] A machine tool coolant filtration device is an indispensable auxiliary equipment in machine tool processing. Its main frame is robust, and it is equipped with multiple filtration components. First, a coarse filter screen intercepts large particles of impurities, preventing them from entering the subsequent precision filtration stage. Next, higher-precision filter elements, such as paper filter elements and metal mesh filter elements, further filter out fine impurities, iron filings, and oil stains, ensuring the coolant meets cleanliness standards. The device is also equipped with an intelligent liquid level monitoring and automatic drainage system, which can monitor the coolant level in real time and promptly remove filtered impurities. Installed next to the machine tool, it continuously purifies the coolant, extends its service life, ensures the machining accuracy of machine tool tools and workpieces, and reduces equipment wear.

[0003] A search revealed that Chinese Patent CN222308213U discloses a machine tool coolant filtration device. This patent describes a dual-chamber configuration with filtration mechanisms installed in each chamber, achieving dual filtration of the coolant and enabling repeated use of the coolant, thus reducing costs. Furthermore, this application provides a technical solution by setting up a storage chamber and installing a liquid level sensor within the storage chamber, thereby enabling the storage of filtered coolant while simultaneously monitoring the coolant level within the storage chamber.

[0004] While this solution achieves dual filtration, it requires disassembly and cleaning of the filter plate before reinstallation when it becomes clogged. This process is time-consuming and labor-intensive, and repeated disassembly can damage the filter plate, significantly reducing work efficiency. To address this technical problem, this invention proposes a machine tool coolant filtration device. Utility Model Content

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Please see Figure 1-4 This utility model provides a technical solution:

[0025] Example 1: A machine tool coolant filtration device includes an outer casing 1, which is divided into left and right compartments. An electric push rod 2 is fixedly connected to one side of the outer casing 1. A filter frame 3 is fixedly connected to the output end of the electric push rod 2. Slide plates 4 are fixedly connected to both outer walls of the filter frame 3. Limiting plates 5 are fixedly connected to both inner walls of the outer casing 1. A motor 6 is fixedly connected to the top of the outer casing 1. A threaded rod 7 is fixedly connected to the output end of the motor 6. A connecting block 8 is threadedly connected to the outer wall of the threaded rod 7. A connecting rod 9 is fixedly connected to the bottom of the connecting block 8. A brush 10 is fixedly connected to the bottom of the connecting rod 9. The brush 10 is located inside the right compartment of the outer casing 1 and is slidably connected to the outer wall of the filter frame 3. A water tank 11 is fixedly connected to the lower exterior of the outer casing 1. A water pump 12 is fixedly connected to one side of the water tank 11. An inlet pipe 13 is fixedly connected to the output end of the water pump 12. Multiple nozzles 14 are provided at the other end of the water pipe 13. The nozzles 14 are located inside the right compartment of the outer box 1 and at the bottom of the filter frame 3. The filter frame 3 is slidably connected to the outer box 1. A guide plate 25 is fixedly connected to the bottom of the right compartment of the outer box 1. A water outlet pipe 15 is provided outside the outer box 1. The other end of the water outlet pipe 15 is fixedly connected to the water tank 11. A water filling pipe 16 is fixedly connected to the top of the water tank 11. A collection box 17 is provided inside the right compartment of the outer box 1. A second limiting plate 18 is fixedly connected to one side wall of the collection box 17. A limiting groove 19 is opened inside the right compartment of the outer box 1, and the second limiting plate 18 is slidably connected to the limiting groove 19. A liquid filling pipe 21 is fixedly connected to the top of the left compartment of the outer box 1. A limiting column 23 is rotatably connected inside the outer box 1. A baffle 24 is fixedly connected to the outer wall of the limiting column 23, and the baffle 24 is rotatably connected to the partition between the left and right compartments of the outer box 1.

[0026] When the filter frame 3 becomes clogged, the drive unit is activated to move the filter frame 3 to the right compartment. During the movement, the slide plate 4 is positioned at the upper limit of the filter frame 3 to ensure smooth movement. The filter frame 3 pushes open the baffle 24 on the limiting post 23 and enters the right compartment of the outer box 1. The motor 6 is activated, which drives the threaded rod 7 to rotate, causing the connecting block 8 and connecting rod 9 to move left and right, thereby driving the brush 10 to clean the filter frame 3. Impurities are brushed into the collection box 17. If impurities block the leak holes of the filter frame 3, the water pump 12 outside the water tank 11 is activated. The water pump draws water from the water tank and sends it to the nozzle 14 through the inlet pipe 13. The nozzle backwashes the filter frame 3, working in conjunction with the brush 10 to clean it. The used water flows through the guide plate 25 into the outlet pipe 15 and returns to the water tank 11 for recycling. Finally, the collection box 17 is pulled out to empty the impurities. The collection box is limited within the limiting groove 19 by the limiting plate 18. These components work together to enable rapid cleaning of the filter frame 3, effectively improving work efficiency.

[0027] Example 2: The difference between this example and Example 1 is that a motor 20 is fixedly connected to the top of the outer box 1, a rotating rod 26 is fixedly connected to the output end of the motor 20, a stirring rod 22 is fixedly connected to the outer wall of the rotating rod 26, and the stirring rod 22 is rotatably connected to the left compartment of the outer box 1.

[0028] First, the machine tool coolant is poured into the left compartment of the outer casing 1 through the filler pipe 21. After being poured in, the coolant will be filtered through the filter frame 3. During this process, the filter frame 3 plays its role in separating impurities from the machine tool coolant. To further improve the filtration efficiency, the second motor 20 on the top of the left compartment of the outer casing 1 is started. The second motor 20 starts working, driving the rotating rod 26 to rotate, and the stirring rod 22 on the rotating rod 26 also rotates accordingly. The rotation of the stirring rod 22 accelerates the flow of the machine tool coolant, thereby accelerating the filtration rate of the coolant.

[0029] Working principle: When the operator needs to filter the machine tool coolant, the coolant is first poured into the left compartment of the outer casing 1 through the filling pipe 21. It then passes through the filter frame 3 for filtration. The filter frame 3 separates impurities from the coolant. Simultaneously, the second motor 20 at the top of the left compartment of the outer casing 1 is activated. Under the action of the second motor 20, the stirring rod 22 on the rotating rod 26 rotates, thereby accelerating the filtration rate of the machine tool coolant. When the filter frame 3 becomes clogged, it is activated, pushing the filter frame 3 towards the right compartment. During this movement, the filter frame 3 is limited by the sliding plate 4. As it moves, the filter frame 3 pushes open the baffle 24 on the limiting post 23 and enters the right compartment of the outer casing 1. At this point, the first motor 6 is activated, driving the threaded rod... 7 rotates, and when the threaded rod 7 rotates, it drives the connecting block 8 and the connecting rod 9 to move left and right, thereby driving the brush 10 to clean the filter outer frame 3. The brush 10 will clean the impurities into the collection box 17. When the impurities block the leakage holes on the filter outer frame 3, the water pump 12 outside the water tank 11 is started. The water pump 12 will draw water from the inside of the water tank 11 and deliver it to the nozzle 14 through the water inlet pipe 13. The nozzle 14 will backflush the filter outer frame 3, thereby flushing out the impurities. Then, in conjunction with the brush 10, it will clean the filter outer frame. The used water flows through the guide plate 25 to the outlet pipe 15 and enters the water tank 11 for recycling. Pull out the collection box 17 to pour out the impurities. The collection box 17 is limited in the limiting groove 19 by the limiting plate 2 18. Through their cooperation, the filter outer frame 3 is cleaned quickly, improving work efficiency.
