Description

Technical Field

[0001] This utility model relates to the field of filter element backwashing mechanisms, specifically to a cutting fluid filter element backwashing mechanism. Background Technology

[0002] The backflushing mechanism for cutting fluid filter elements is a core device used to maintain the performance of the cutting fluid filtration system. Its core function is to remove impurities clogging the surface and interior of the filter element through reverse fluid flushing (or combined with mechanical cleaning), thereby restoring the filter element's filtration capacity and extending its service life.

[0003] Traditional cutting fluid filter elements are mostly rinsed using a simple nozzle during the flushing process. However, this simple flushing method has limited effectiveness in cleaning stubborn blockages and cannot effectively and quickly backwash the filter element.

[0004] Therefore, it is necessary to invent a backwashing mechanism for cutting fluid filter elements to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a backwashing mechanism for a cutting fluid filter element. By connecting the flushing connector to an external water pipe connector, water enters the connecting pipe and the delivery pipe. Multiple nozzles on the outside of the delivery pipe flush the exterior of the filter element assembly. At this time, the drive motor switch is turned on, driving the second spur gear to rotate. The rotation of the second spur gear meshes with the first spur gear on the outside of the connecting pipe, thereby causing the connecting pipe to drive the delivery pipe and the nozzles to rotate. Meanwhile, the connecting rod and scraper fixed on the other side below the connecting pipe, which are attached to the outside of the filter element assembly, also rotate together, thus achieving simultaneous flushing and scraping. This solves the problem mentioned in the background art that traditional cutting fluid filter elements mostly use only simple nozzles to flush the filter element during the flushing process. Such a simple flushing method has limited effectiveness in cleaning stubborn blockages and cannot effectively and quickly backwash the filter element.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a backwashing mechanism for a cutting fluid filter element, including a flushing connector for connecting an external water pipe to flush the filter element;

[0007] A flushing connector is located above the filter cylinder. The filter cylinder has an inlet on one side of its upper surface and a slag outlet at its lower surface. A connecting pipe is rotatably connected inside the filter cylinder. A first spur gear is fixedly connected to the outside of the connecting pipe. A conveying pipe is fixedly connected to one side of the lower surface of the connecting pipe. Nozzles are provided on the inner side of the conveying pipe. A connecting rod is fixedly connected to the other side of the lower surface of the connecting pipe. A connecting frame is fixedly connected to the front end of the connecting rod. A scraper is installed inside the connecting frame. A drive motor is fixedly installed on the rear upper surface of the filter cylinder. A second spur gear is fixedly connected to the output end of the drive motor.

[0008] The filter cartridge assembly is located inside the filter cylinder and is used for filtration.

[0009] Preferably, the connecting pipe is internally connected to the flushing connector, and the connecting pipe is rotatably connected to the flushing connector.

[0010] Preferably, the inner cavity of the connecting pipe is connected to the inner cavity of the delivery pipe, and the nozzle is equipped with a filter screen.

[0011] Preferably, the connecting frame has an internal mounting groove, and a spring is fixedly connected inside the mounting groove. The rear end of the scraper is fixedly connected to the front end of the spring.

[0012] Preferably, the scraper is attached to the outside of the filter element assembly, the bottom end of the filter element assembly is connected to the slag discharge port, and a valve is provided on the outside of the slag discharge port.

[0013] Preferably, the outer side of the second spur gear meshes with the rear side of the first spur gear.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] This invention, through the arrangement of a flushing connector, connecting pipe, first spur gear, conveying pipe, nozzle, connecting rod, scraper, drive motor, and second spur gear, not only enables reverse flushing but also enhances the overall flushing effect by simultaneously flushing and cleaning with the scraper. By connecting the flushing connector to an external water pipe joint, water enters the connecting pipe and conveying pipe. Multiple nozzles on the outside of the conveying pipe flush the exterior of the filter element assembly. At this time, turning on the drive motor switch drives the second spur gear to rotate. The rotation of the second spur gear meshes with the first spur gear on the outside of the connecting pipe, thereby causing the connecting pipe to drive the conveying pipe and nozzle to rotate. Meanwhile, the connecting rod and scraper fixed on the other side below the connecting pipe, which are attached to the outside of the filter element assembly, also rotate together, thus achieving simultaneous flushing and scraping.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model provides, for example Figure 1-4 The cutting fluid filter cartridge backwashing mechanism shown includes a flushing connector 1 for connecting an external water pipe to flush the filter cartridge.

[0025] A flushing connector 1 is located above the filter cylinder 2. A liquid inlet 3 is provided on one side of the upper part of the filter cylinder 2, and a slag discharge port 4 is provided on the lower part of the filter cylinder 2. A connecting pipe 5 is rotatably connected inside the filter cylinder 2. A first spur gear 6 is fixedly connected to the outside of the connecting pipe 5. A conveying pipe 7 is fixedly connected to one side of the lower part of the connecting pipe 5. A nozzle 8 is provided on the inner side of the conveying pipe 7. A connecting rod 9 is fixedly connected to the other side of the lower part of the connecting pipe 5. A connecting frame 10 is fixedly connected to the front end of the connecting rod 9. A scraper 13 is provided inside the connecting frame 10. A drive motor 15 is fixedly installed on the rear side of the upper part of the filter cylinder 2. A second spur gear 16 is fixedly connected to the output end of the drive motor 15.

[0026] The filter element assembly 14 is installed inside the filter cylinder 2 for filtration. By connecting the rinsing connector 1 to the external water pipe connector, water enters the connecting pipe 5 and the delivery pipe 7. Multiple nozzles 8 outside the delivery pipe 7 rinse the outside of the filter element assembly 14. At this time, the drive motor 15 is turned on, which drives the second spur gear 16 to rotate. The rotation of the second spur gear 16 meshes with the first spur gear 6 outside the connecting pipe 5, thereby causing the connecting pipe 5 to drive the delivery pipe 7 and the nozzles 8 to rotate. At the same time, the connecting rod 9 and the scraper 13 fixed on the other side below the connecting pipe 5 also rotate together, thus realizing rinsing and scraping at the same time.

[0027] like Figure 1 and Figure 3 As shown, the connecting pipe 5 is internally connected to the flushing connector 1. The connecting pipe 5 and the flushing connector 1 are rotatably connected. Water is supplied from the flushing connector 1 to the connecting pipe 5 through an external water pipe. The connecting pipe 5 is rotatably connected to the top of the filter cylinder 2. The flushing connector 1 and the connecting pipe 5 are also rotatably connected. Therefore, when supplying water, it will not affect the normal rotation of the nozzle 8 and scraper 13 driven by the connecting pipe 5.

[0028] like Figure 3 As shown, the inner cavity of the connecting pipe 5 is connected to the inner cavity of the delivery pipe 7. The nozzle 8 is equipped with a filter screen. When the water source is delivered to the delivery pipe 7 through the connecting pipe 5, the water source is delivered to the nozzle 8 and sprayed out through the delivery pipe 7. The nozzle 8 is equipped with a filter screen to prevent some impurities from entering the nozzle 8 during the cutting fluid filtration process.

[0029] like Figure 3 and Figure 4 As shown, the connecting frame 10 has an installation groove 11 inside, and springs 12 are fixedly connected inside each installation groove 11. The rear end of the scraper 13 is fixedly connected to the front end of the springs 12. Under the action of the rebound of multiple sets of springs 12 on the rear side, the scraper 13 can stick to the outside of the filter element assembly 14, which not only enhances the cleaning effect, but also avoids excessive force that could damage the filter element assembly 14.

[0030] like Figure 3 and Figure 4 As shown, the scraper 13 is attached to the outside of the filter element assembly 14. The bottom end of the filter element assembly 14 is connected to the slag discharge port 4. A valve is provided on the outside of the slag discharge port 4. When the washed impurities enter the filter element assembly 14, the bottom end of the filter element assembly 14 is connected to the slag discharge port 4. By opening the valve on the outside of the slag discharge port 4, the washed impurities inside are discharged.

[0031] like Figure 3As shown, the outer side of the second spur gear 16 meshes with the rear side of the first spur gear 6. By turning on the drive motor 15 switch, the second spur gear 16 is driven to rotate. The rotation of the second spur gear 16 drives the first spur gear 6 to mesh and transmit power, so that the first spur gear 6 drives the internal connecting pipe 5 to rotate at the top of the flushing connector 1. The connecting pipe 5 drives the nozzles 8 and scrapers 13 on both sides of the lower end to rotate outside the filter element assembly 14, which enhances the backwashing effect.

[0032] The working principle of this utility model is as follows: First, connect the external power supply. When backwashing the cutting fluid filter element is required, connect the flushing connector 1 to the external water pipe, allowing water to enter the connecting pipe 5 and the delivery pipe 7. Multiple nozzles 8 on the outside of the delivery pipe 7 then flush the exterior of the filter element assembly 14. At this time, turn on the drive motor 15, which drives the second spur gear 16 to rotate. The rotation of the second spur gear 16 meshes with the first spur gear 6 on the outside of the connecting pipe 5, causing the connecting pipe 5 to rotate inside the top of the filter cylinder 2. This, in turn, drives the delivery pipe 7 and nozzles 8 on one side of the lower end of the connecting pipe 5 to rotate. Simultaneously, the rotation of the connecting pipe 5 also drives... The connecting rod 9 fixed on the other side of the lower end rotates together with the scraper 13 against the outside of the filter element assembly 14, thereby achieving simultaneous rinsing and scraping. The scraper 13 is pushed by the rebound of multiple sets of springs 12 on the rear side, which allows the scraper 13 to stick to the outside of the filter element assembly 14, which not only enhances the cleaning effect, but also avoids excessive force that could damage the filter element assembly 14. Finally, the impurities after backwashing enter the interior of the filter element assembly 14 and are connected to the slag discharge port 4 at the bottom of the filter element assembly 14. Then, the valve outside the slag discharge port 4 is opened to discharge the cleaned impurities inside. In this way, the use process of the cutting fluid filter element backwashing mechanism is completed.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
