Description

Technical Field

[0001] This utility model relates to the field of emulsion filtration technology, and in particular to an emulsion filtration device for steel plate processing. Background Technology

[0002] Effective filtration of emulsions is crucial in steel plate processing. Currently, most commercially available emulsion filtration devices for steel plate processing employ a single filter screen combined with a simple vibration device to filter metal debris and prevent clogging. However, in practical use, this method has several shortcomings. As filtration continues, a large amount of debris rapidly accumulates on the filter screen surface, and vibration alone is insufficient to completely remove the tightly adhered debris. This leads to a continuous decrease in the effective filtration area of ​​the filter screen, a sharp increase in filtration resistance, and a significant drop in filtration efficiency. This not only necessitates frequent filter screen replacements, increasing maintenance costs, but also affects the circulation and supply of emulsions, thereby disrupting the continuity and stability of steel plate processing.

When in contact, it performs cleaning work, and when it moves away, it does not affect the filtration process, ensuring the feasibility and effectiveness of the cleaning work, extending the service life of the first filter plate, and improving the filtration efficiency.

[0030] In a preferred embodiment, the horizontal drive assembly includes a servo motor 10, a lead screw 9, and a moving block 11. The servo motor 10 is fixedly connected to the outer wall of the filter box 1 on the side away from the insertion window. Both ends of the lead screw 9 are rotatably connected to the filter box 1, and the end of the lead screw 9 extending out of the filter box 1 is fixedly connected to the output shaft of the servo motor 10. The moving block 11 is provided with a threaded hole for threaded connection with the lead screw 9 to move horizontally during the rotation of the lead screw 9. The bottom end of the moving block 11 is fixedly connected to the vertical drive assembly. This structural design provides a precise drive method for the horizontal movement of the vertical drive assembly and the scraper 13. The stable operation of the servo motor 10 drives the lead screw 9 to rotate. The threaded connection between the lead screw 9 and the moving block 11 can convert the rotational motion into stable linear motion, thereby accurately pushing the scraper 13 to move horizontally above the first filter plate, ensuring the accuracy of the cleaning work.

[0031] In a preferred embodiment, a guide rod 14 is also included. The movable block 11 is provided with a through hole. The guide rod 14 is arranged parallel to the lead screw 9. The guide rod 14 passes through the through hole and is slidably connected to the movable block 11. Both ends of the guide rod 14 are fixedly connected to the filter box 1. The guide rod 14 provides guidance for the movement of the movable block 11, ensuring that the movable block 11 moves smoothly along the direction of the lead screw 9, preventing the movable block 11 from deviating during the movement, improving the stability of the scraper 13 movement, and thus improving the reliability of the cleaning work.

[0032] In a preferred embodiment, the vertical drive assembly includes an electric telescopic rod 17.

When cleaning is not required, the scraper 13 can be driven away from the first filter plate without hindering the normal filtration of the emulsion, making the equipment more flexible in use.

[0033] In a preferred embodiment, the system further includes a waterproof shell 12 and multiple guide rods 18. The waterproof shell 12 is fixedly connected to the lower part of the movable block 11. The bottom of the waterproof shell 12 is provided with a waterproof groove and multiple guide grooves. The electric telescopic rod 17 is disposed within the waterproof groove and fixedly connected to the waterproof shell 12. The telescopic end of the electric telescopic rod 17 is fixedly connected to the scraper 13. Each guide rod 18 is fixedly connected to the scraper 13, and the top end of each guide rod 18 extends into the guide groove to guide the telescopic direction of the electric telescopic rod 17. The waterproof shell 12 protects the electric telescopic rod 17, preventing emulsions and other liquids from intruding and affecting its normal operation. The guide rods 18 cooperate with the guide grooves to further ensure that the electric telescopic rod 17 telescopics in the correct direction, guaranteeing the straightness and accuracy of the scraper 13's movement and improving the cleaning effect.

[0034] In a preferred embodiment, the scraper 13 is a trapezoidal scraper 13, and the side of the trapezoidal scraper 13 with a larger cross-sectional area is closer to the first filter plate. This shape design of the trapezoidal scraper 13 increases the contact area between the scraper 13 and the surface of the first filter plate, which can more effectively push the metal debris on the surface of the first filter plate towards the collection box 7 and improve cleaning efficiency.

[0035] In a preferred embodiment, the system further includes a first sensor 15 and a second sensor 16. The first sensor 15 is disposed on the inner wall of the filter box 1 corresponding to the insertion window. The first sensor 15 is signal-connected to the electric telescopic rod 17 to control the electric telescopic rod 17 to drive the scraper 13 away from the first filter plate and hold it in place when the moving block 11 contacts the first sensor 15. The second sensor 16 is disposed on the inner wall of the filter box 1 corresponding to the servo motor 10. The second sensor 16 is signal-connected to the electric telescopic rod 17 to control the electric telescopic rod 17 to extend and retract when the moving block 11 contacts the second sensor 16, driving the scraper 13 downward to contact and hold the first filter plate. The first sensor 15 and the second sensor 16 precisely control the working position and state of the scraper 13, realizing automated operation. When the scraper 13 moves to a specific position, the sensor can promptly send a signal to control the extension and retraction of the electric telescopic rod 17, ensuring that the scraper 13 cleans the first filter plate according to the set program, avoiding over-cleaning or under-cleaning, and improving the intelligence and reliability of the device.

[0036] In a preferred embodiment, the collection box 7 includes a collection tank, a second filter plate 27, a push plate, and a handle. The bottom of the collection tank is provided with a drain port 28. The second filter plate 27 is disposed in the collection tank. The push plate is disposed on one side of the collection tank. The handle is disposed on the side of the push plate away from the collection tank. The collection tank is used to collect metal scraps and part of the emulsion. The second filter plate 27 further filters the emulsion in the collection box 7. The drain port 28 can discharge the filtered emulsion back to the filtration system for recycling. The push plate and handle make it convenient for workers to push the debris in the collection box 7 when needed to clean the collection box 7, which improves the convenience and functionality of the collection box 7.

[0037] In a preferred embodiment, the collection box 7 further includes a slider 25, which is disposed on one side of the collection tank. A slot 26 is provided on one side of the insertion window. The slider 25 is slidably connected to the slot 26 to limit the position of the collection box 7. The cooperation between the slider 25 and the slot 26 ensures the accuracy and stability of the position of the collection box 7 during installation and use, and prevents the collection box 7 from shaking or shifting on the filter box 1, thereby ensuring the normal realization of the function of collecting metal debris.

[0038] In a preferred embodiment, the system further includes a door 23. The first filter plate includes a support frame 3, a filter screen 4, multiple springs 22, and multiple limiting blocks 20. The outer periphery of the support frame 3 is fixedly connected to the interior of the filter box 1. The support frame 3 is positioned in an installation groove, and the filter screen 4 is placed within the installation groove. Multiple limiting grooves 21 are provided on one side of the filter screen 4, and multiple recesses 19 are provided on one side of the support frame 3. The recesses 19 correspond to the limiting grooves 21. The springs 22 are positioned within the recesses 19, with one end fixedly connected to the support frame 3 and the other end fixedly connected to the limiting block 20, so as to push the limiting block 20 against the limiting groove 21. The door 23 facilitates maintenance and cleaning operations inside the filter box 1 by personnel. The structural design of the first filter plate ensures that the filter screen 4 is securely installed. The cooperation between the springs 22 and the limiting blocks 20 ensures the secure installation of the filter screen 4 while facilitating disassembly and replacement when needed, improving the ease of installation and removal of the filter screen 4 and reducing maintenance costs.

[0039] In a preferred embodiment, the top of the limiting block 20 is an arc-shaped structure. During installation and disassembly, the top of the limiting block 20 with an arc-shaped structure is easier to guide the limiting block 20 into and out of the limiting groove 21, reducing frictional resistance between the limiting block 20 and the limiting groove 21, making the operation smoother, and further improving the disassembly and installation efficiency of the filter screen 4.

[0040] In a preferred embodiment, a flow guide slope 8 is also included. The flow guide slope 8 is disposed at the bottom of the filter box 1, and the top surface of the flow guide slope 8 is inclined from the side near the first filter plate toward the outlet pipe 5.

[0041] The method of using the emulsion filtration device for steel plate processing provided by this utility model

[0042] Equipment installation and preparation phase

[0043] Connect the inlet pipe 2 and the outlet pipe 5: Accurately connect the top end of the inlet pipe 2 to the emulsion discharge port used after the steel plate is processed, ensuring a good seal to prevent emulsion leakage. At the same time, check the outlet pipe 5 to confirm that the solenoid valve 6 is installed correctly and can work normally, ensuring that the outlet pipe 5 is unobstructed.

[0044] Install the first filter plate: Securely connect the outer periphery of the support frame 3 of the first filter plate to the pre-set mounting groove inside the filter box 1, and accurately place the filter screen plate 4 into the mounting groove of the support frame 3. At this time, under the elastic force of the spring 22, the limiting block 20 is firmly pressed into the limiting groove 21 on one side of the filter screen plate 4. The arc-shaped structure at the top of the limiting block 20 plays a positive role in the installation process. It guides the limiting block 20 smoothly into the limiting groove 21, reduces obstacles in the installation process, and ensures that the first filter plate is installed firmly and in a precise position.

[0045] Insert the receiving box 7: Slide the receiving box 7 along the slot 26 on the side of the insertion window on the filter box 1 using the slider 25 to ensure that the receiving box 7 is firmly inserted into the filter box 1, and that the part of the receiving box 7 extending into the filter box 1 is exactly below the discharge port.

[0046] Filtering work phase

[0047] After the steel plate processing generates an emulsion, the emulsion carrying metal debris flows into the filter box 1 through the inlet pipe 2. Since the first filter plate is horizontally positioned below the inlet pipe 2, the emulsion falls naturally under gravity and contacts the first filter plate. The first filter plate performs fine filtration of the emulsion, intercepting the metal debris, while the filtered emulsion continues to fall. At this point, the solenoid valve 6 in the outlet pipe 5 is opened. Guided by the flow guide slope 8 at the bottom of the filter box 1, the emulsion flows more smoothly along the inclined top surface to the outlet pipe 5 and is discharged for reuse. The flow guide slope 8 prevents the emulsion from accumulating at the bottom of the filter box 1, greatly improving the discharge efficiency and ensuring smooth operation of the entire filtration process.

[0048] Cleanup phase

[0049] As the filtration process continues, metal debris will accumulate on the surface of the first filter plate. When cleaning is required, activate the cleaning mechanism:

[0050] Scraper 13 contacts the first filter plate: The electric telescopic rod 17 extends, driving the scraper 13 downward until it makes close contact with the surface of the first filter plate. During this process, the guide groove and guide rod 18 at the bottom of the waterproof shell 12 cooperate with each other to precisely guide the extension and retraction direction of the electric telescopic rod 17, ensuring that the scraper 13 can accurately contact the first filter plate and make good contact. At the same time, the horizontal drive assembly starts working, the servo motor 10 starts, and drives the lead screw 9 to rotate. The threaded connection between the lead screw 9 and the moving block 11 causes the moving block 11 to move horizontally along the length of the lead screw 9 during the rotation of the lead screw 9. The guide rod 14 passes through the through hole of the moving block 11 to guide its sliding, ensuring that the moving block 11 moves horizontally smoothly and accurately. The moving block 11 drives the vertical drive assembly, the waterproof shell 12 and the scraper 13 to move horizontally together, so that the scraper 13 performs a reciprocating cleaning action on the surface of the first filter plate, sweeping the accumulated metal debris along the discharge port into the collection box 7 below.

[0051] Scraper 13 position control: When the moving block 11 moves to the side near the collection box 7 and contacts the first sensor 15 on the inner wall of the filter box 1, the first sensor 15 transmits a signal to the electric telescopic rod 17. The electric telescopic rod 17 then drives the scraper 13 to disengage from the first filter plate and maintain that position. Subsequently, the servo motor 10 reverses its rotation, driving the moving block 11 back to its initial position. When the moving block 11 returns to the other end and contacts the second sensor 16, the second sensor 16 sends a signal to the electric telescopic rod 17, which then pushes the scraper 13 downwards again until it contacts the first filter plate. In this way, precise control of the scraper 13's position is achieved using the first sensor 15 and the second sensor 16, effectively preventing debris from being carried away from the collection box 7 during the reciprocating cleaning process, thus maintaining the cleanliness of the first filter plate surface.

[0052] Collection Box 7 Cleaning Stage

[0053] As the debris collected in the collection box 7 increases, when cleaning is required, the operator holds the handle on the push plate and pulls the collection box 7 out of the filter box 1 along the slot 26. At this time, the debris inside the collection box 7 can be cleaned. The second filter plate 27 inside the collection box 7 can further filter the emulsion entering the collection box 7. The filtered emulsion flows out through the drain port 28 at the bottom and flows back into the filter box 1 for reuse. After cleaning, the collection box 7 is reinserted into the slot 26, ensuring that the slider 25 is accurately engaged to ensure that the collection box 7 is in a stable position.

[0054] First filter plate replacement stage

[0055] When the first filter plate needs to be replaced, open the door 23 of the filter box 1, and the operator reaches inside the filter box 1, pulls the bottom of the filter plate, and gently applies downward pressure. At this time, under the guidance of the limiting block 20 and the arc-shaped end of the limiting groove 21, the inner wall of the limiting groove 21 presses against the arc-shaped end of the limiting block 20, causing the limiting block 20 to move into the groove 19 against the elastic force of the spring 22. After the filter plate loses its limiting position, it can be pulled out directly from the filter box 1 at an angle. When replacing the new filter plate, gently insert it back into the mounting groove of the support frame 3. When the limiting groove 21 and the limiting block 20 are at the same horizontal line, the elastic ejection action of the spring 22 pushes the limiting block 20 back into the limiting groove 21, thereby achieving a firm limiting of the filter plate.

[0056] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
