[0002] Cutting fluid is an industrial liquid used in metal cutting and grinding processes to cool and lubricate cutting tools and workpieces. Cutting fluid is scientifically formulated with a variety of high-performance additives, and has good cooling, lubrication, rust prevention, degreasing and cleaning, corrosion prevention, and easy dilution properties. The filter screens of existing filtration devices are not easy to clean. Cleaning the filter screen requires disassembling the device casing, which increases the workload of operators and reduces work efficiency. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides a filtration device for cutting fluid in CNC machine tool processing, which effectively solves the problem that the filter screen of the existing filtration device is not easy to clean and that the outer shell of the device needs to be disassembled when cleaning the filter screen.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a filtration device for cutting fluid in CNC machine tool processing, comprising a device base plate, a collection box fixedly installed on one side of the top of the device base plate, an inlet port on the top of the collection box, a drain valve fixedly installed on the lower part of one side of the collection box, an installation frame inside the collection box, a filter screen fixedly installed inside the installation frame, a limit block fixedly installed on one side of the installation frame, a limit groove opened on the inner wall of the collection box near the drain valve, the limit block installed inside the limit groove, and a quick-release assembly provided between the inside of the device base plate and the upper part of the device base plate, the quick-release assembly being fixedly connected to the installation frame.

[0005] Preferably, the quick removal component includes a first drive motor and an opening. The first drive motor is fixedly installed on one side of the inner wall of the device base plate, and the opening is opened on the surface of the collection box away from the drain valve. A threaded rod is fixedly installed at the output end of the first drive motor, and a positioning shaft seat is rotatably installed at the end of the threaded rod away from the first drive motor. One side of the positioning shaft seat is fixedly connected to the other side of the inner wall of the device base plate.

[0006] Preferably, the threaded rod is threadedly connected to a threaded sleeve, a positioning sleeve is fixedly installed on the lower side of the threaded sleeve, a positioning slide rod is inserted into the inside of the positioning slide sleeve, one end of the positioning slide rod is fixedly connected to the inner wall of the device base plate, a fixing block is fixedly installed on the other end of the positioning slide rod, the bottom of the fixing block is fixedly connected to the bottom of the device base plate, a support rod is fixedly installed on the top of the threaded sleeve, and an mounting plate is fixedly installed on the top of the support rod.

[0007] Preferably, the mounting plate has a through hole inside, a second drive motor is fixedly installed on one side of the mounting plate, and a positioning bushing is fixedly installed on the other side of the mounting plate. A rotating shaft is rotatably installed inside the positioning bushing. One end of the rotating shaft extends into the through hole and is fixedly connected to the output end of the second drive motor. The other end of the rotating shaft is fixedly installed on a sealing plate. The sealing plate is installed inside the opening and is fixedly connected to the mounting frame.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: the used cutting fluid enters the inside of the collection tank through the inlet, the cutting fluid inside the collection tank is filtered through the filter screen, and the filtered cutting fluid is discharged through the drain valve for recycling; when there are many impurities on the filter screen, the operator starts the first drive motor to drive the threaded rod to rotate along the positioning shaft seat. When the threaded rod rotates, it drives the threaded sleeve to move. When the threaded sleeve moves, it drives the positioning slide sleeve to slide along the surface of the positioning slide rod, which increases the stability of the threaded sleeve when it moves. When the threaded sleeve moves, it drives the mounting plate to move through the support rod. When the mounting plate moves, it pulls the sealing plate through the rotating shaft.

[0009] When the sealing plate is pulled, it moves the filter screen outward through the mounting frame. As the mounting frame moves, it moves the limiting block out of the limiting groove. After the filter screen is completely moved to the outside, the operator places the external receiving hopper under the filter screen. Then, the operator starts the second drive motor to drive the rotating shaft to rotate along the inside of the positioning sleeve. When the rotating shaft rotates, it causes the filter screen to flip through the sealing plate and mounting frame, allowing impurities on the filter screen to fall onto the receiving hopper for collection. This makes cleaning the filter screen of this filtration device very convenient, reduces the workload of the operator, and improves work efficiency. Attached Figure Description

[0018] Used cutting fluid enters the collection tank 2 through inlet 3. Inside the collection tank 2, the cutting fluid is filtered through filter screen 6. The filtered cutting fluid is then discharged through drain valve 4 for recycling. When there are many impurities on filter screen 6, the operator activates the quick-release assembly. The quick-release assembly moves filter screen 6 outward via mounting frame 5. As mounting frame 5 moves, it moves limit block 7 out of limit groove 8. After filter screen 6 is completely removed, the operator places the external receiving hopper below filter screen 6. The operator then continues to control the quick-release assembly, which, via mounting frame 5, flips filter screen 6, allowing impurities on filter screen 6 to fall into the receiving hopper for collection. This makes cleaning filter screen 6 of this filtration device very convenient, reducing the workload of operators and improving work efficiency.

The other end of the rotating shaft 20 is fixedly installed on a sealing plate 22. The sealing plate 22 is installed inside the opening 23 and is fixedly connected to the mounting frame 6.

[0020] The operator starts the first drive motor 9, which drives the threaded rod 10 to rotate along the positioning shaft seat 11. When the threaded rod 10 rotates, it drives the threaded sleeve 12 to move. When the threaded sleeve 12 moves, it drives the positioning slide sleeve 13 to slide along the surface of the positioning slide rod 14, which increases the stability of the threaded sleeve 12 when it moves.
