Description

Technical Field

[0001] This utility model relates to the field of paint filtration technology, and in particular to a filtration device for paint processing that is easy to clean quickly. Background Technology

[0002] In the coatings processing industry, the quality of the coating plays a crucial role in the final performance of the product. During the coating production process, various impurities, such as particles and fibers, are often mixed into the raw materials. If these impurities are not removed, they will seriously affect the quality of the coating, leading to problems such as coating defects and reduced adhesion. Therefore, filtration devices have become an indispensable part of the coating processing flow. They can effectively remove impurities, ensure the quality of the coating, and meet the stringent requirements of different fields. They are widely used in coating production in many industries such as construction, automobiles, and furniture.

[0003] Currently, common paint processing filtration devices on the market have some significant shortcomings. Traditional filtration devices rely solely on a single filtration structure to intercept impurities when filtering paint, lacking any agitation measures for the paint. As the filtration process continues, some components in the paint easily settle or separate, leading to a gradual decrease in filtration efficiency. Moreover, impurities tend to accumulate in the pores of the filter components during filtration, causing blockages. Once the filter components are blocked, not only will the filtration speed be significantly reduced, but the filtration process may even cease. To maintain normal operation, operators must frequently stop the machine to clean the filter components. This not only increases the number of production interruptions and extends the production cycle but also greatly affects production efficiency and increases production costs. Therefore, to address the problem that existing filtration devices rely solely on a single filtration structure to intercept impurities and lack agitation measures for the paint, a paint processing filtration device that solves the above problems and is easy to clean is needed. Utility Model Content

[0004] To address the problem that existing filtration devices rely solely on a single filtration structure to intercept impurities when filtering coatings, lacking any agitation measures for the coating, this application provides a filtration device for coating processing that is easy to clean quickly. The rotating agitator roller stirs the coating, accelerating the filtration speed, while the rotating brush cleans the filter cylinder pores to prevent clogging. This achieves simultaneous filtration and self-cleaning. When cleaning the filter cylinder is required, it can be quickly disassembled and cleaned with simple operations such as moving the connecting plate or pulling the lever. Reinstallation after cleaning is also convenient, allowing for quick repositioning and fixation.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0030] Example 1:

[0031] like Figures 1-5As shown, a filtration device for paint processing that is easy to clean quickly includes a filter barrel 1. A top cover 7 is connected to the top side of the outer wall of the filter barrel 1 via a fixing plate 3, a connecting plate 4, a clamping rod 5, and a clamping sleeve 6. A washer 21 is fixedly connected to the bottom end of the top cover 7. The washer 21 is set at the top of the filter barrel 1. A fixing ring 14 is fixedly connected to the bottom end of the top cover 7. A filter cylinder 19 is connected to the inner wall of the fixing ring 14 via a pull rod 15, a limiting plate 17, and a limiting member 16. A motor 10 is mounted on the top of the top cover 7 via a fixing frame. A rotating rod 11 is fixedly connected to the drive end of the motor 10. A stirring roller 12 is fixedly connected to the middle of the outer wall of the rotating rod 11. A brush 13 is fixedly connected to the bottom side of the outer wall of the rotating rod 11. Both the stirring roller 12 and the brush 13 are rotatably connected to the inner circumference of the filter cylinder 19. A feed pipe 9 is fixedly connected to the left side of the top of the top cover 7. A discharge pipe 23 is fixedly connected to the bottom end of the filter barrel 1.

[0032] Specifically, the motor 10 drives the rotating rod 11 to rotate at high speed. The stirring roller 12 in the middle of the outer wall of the rotating rod 11 and the brush 13 on the bottom side rotate synchronously. During the filtration process, the stirring roller 12 rotates continuously, stirring the coating in the filter cylinder 19. This not only makes the coating more uniformly mixed, avoiding sedimentation or stratification, but also speeds up the speed at which the coating passes through the filter cylinder 19, improving filtration efficiency. At the same time, the brush 13 rotates continuously, constantly cleaning the holes on the filter cylinder 19, effectively preventing impurities in the coating from clogging the holes, ensuring that the filtration work can be carried out continuously and smoothly. The coating to be filtered is slowly injected into the filter barrel 1 through the feed pipe 9. After entering the filter barrel 1 through the feed pipe 9, the coating falls directly into the filter cylinder 19. The filter cylinder 19 performs fine filtration of the coating, intercepting impurities in the coating. The coating filtered by the filter cylinder 19 falls onto the guide member 22 on the inner wall of the filter barrel 1. The inverted conical groove design in the middle of the guide component 22 can guide the coating to flow smoothly to the discharge pipe 23 and be discharged from the filter device through the discharge pipe 23.

[0033] The fixed plate 3 is located on the top side of the outer wall of the filter barrel 1. A connecting plate 4 is rotatably connected to the side of the fixed plate 3 away from the filter barrel 1. A clamping rod 5 is rotatably connected to the outer wall of the connecting plate 4. A clamping sleeve 6 is provided at the top of the clamping rod 5. The clamping sleeve 6 is fixedly connected to the outer wall of the top cover 7. A flow guide 22 is fixedly connected to the inner wall of the filter barrel 1. An inverted conical groove is provided in the middle of the flow guide 22. A handle 8 is fixedly connected to the top of the top cover 7. A base frame 2 is fixedly connected to the bottom of the filter barrel 1.

[0034] Specifically, by manually moving the connecting plate 4, which is rotatably connected to the fixing plate 3 and the locking rod 5, moving the connecting plate 4 will cause the locking rod 5 to move, disengaging the locking sleeve 6 at the top of the locking rod 5 from the slot. This removes the restriction on the top cover 7. Conversely, by placing the top cover 7 back onto the filter bucket 1 and adjusting its position, the locking rod 5 is placed into the groove of the locking sleeve 6. Then, the connecting plate 4 is pressed down to make the locking rod 5 parallel to the connecting plate 4, thus fixing the filter bucket 1 and the top cover 7. During this process, the rubber gasket 21 fixedly connected to the bottom of the top cover 7 acts as a seal and buffer, preventing paint leakage and ensuring a tighter and more stable fixation between the filter bucket 1 and the top cover 7. The handle 8 is fixed to the top of the top cover 7, making it easy for the operator to lift or move the top cover 7, facilitating the installation and removal of the filter bucket 19. The base frame 2 supports the filter bucket 1, allowing the device to be placed stably on the workbench, ensuring that the device will not shake or tip over during the filtration process.

[0035] Example 2:

[0036] As one of the optimized structural designs for Example 1, such as Figures 1-5 As shown, a pull rod 15 is located on the inner wall of the fixed ring 14. A limiting plate 17 is fixedly connected to the top outer wall of the pull rod 15. The limiting plate 17 is slidably connected to the inner wall of the fixed ring 14. A limiting element 16 is provided on the bottom outer wall of the pull rod 15. The limiting element 16 is provided on the inner wall of the filter cylinder 19. A spring 18 is provided on the top outer wall of the pull rod 15. One end of the spring 18 is connected to the fixed ring 14, and the other end of the spring 18 is connected to the limiting plate 17. A tenon 20 is fixedly connected to the top of the filter cylinder 19. The tenon 20 is provided on the inner wall of the fixed ring 14.

[0037] Specifically, by pulling the lever 15 on the inner wall of the retaining ring 14, the limiting plate 17 fixedly connected to the top outer wall of the lever 15 will slide on the inner wall of the retaining ring 14, simultaneously compressing the spring 18. As the lever 15 is pulled, the limiting piece 16 set on the bottom outer wall of the lever 15 will be removed from the groove on the inner wall of the filter cartridge 19, thereby quickly releasing the limiting of the filter cartridge 19. This allows the filter cartridge 19 to be separated from the retaining ring 14, facilitating a thorough cleaning of the filter cartridge 19. After cleaning, the filter cartridge 19 can be reinstalled. Hold the handle 8 and align the groove on the retaining ring 14 with the tenon 20 at the top of the filter cartridge 19, inserting the tenon 20 into the groove of the retaining ring 14 to complete the initial positioning of the filter cartridge 19. Next, pull the lever 15 again to make the retaining ring 14 and the filter cartridge 19 come into tight contact, and then release the force applied to the lever 15. At this time, the spring 18 will return to its original state, pushing the limiting plate 17 and the pull rod 15 to move downward, so that the limiting member 16 is re-inserted into the groove of the filter cylinder 19, thereby completing the fixation between the fixing ring 14 and the filter cylinder 19.

[0038] Working principle: The motor 10 is started, which drives the stirring roller 12 and brush 13 to rotate via the rotating rod 11. The paint to be filtered is then injected into the filter tank 1 through the feed pipe 9. The paint entering the filter tank 1 through the feed pipe 9 falls into the filter cylinder 19 for filtration. After filtration, it falls onto the guide member 22 and flows out through the discharge pipe 23. While the paint is being filtered in the filter cylinder 19, the rotation of the stirring roller 12 agitates the paint, and the rotation of the brush 13 agitates the filter cylinder 19. Clean the holes on the filter cylinder 19 to prevent it from being clogged by the coating. When the coating filtration is complete and the filter cylinder 19 needs cleaning, move the connecting plate 4 to move the locking rod 5, causing the locking rod 5 to move out of the slot in the sleeve 6, thereby releasing the limit on the top cover 7. Then, grasp the handle 8 and lift it upward to remove the filter cylinder 19 from the filter barrel 1. Then, pull the pull rod 15 on the fixing ring 14, which will compress the spring 18 through the limiting plate 17, causing the limiting member 16 to move out of the groove in the filter cylinder 19. Remove the filter cartridge 19 to quickly release its limiting position. Then, separate the filter cartridge 19 from the retaining ring 14 to clean it. After cleaning, hold the handle 8, align the groove on the retaining ring 14 with the tenon 20, and insert the tenon 20 into the groove of the retaining ring 14 to position the filter cartridge 19. Then, pull the lever 15 to make contact between the retaining ring 14 and the filter cartridge 19. Afterward, release the force applied to the lever 15, allowing the spring 18 to... Insert the limiting piece 16 into the groove of the filter cylinder 19 to fix the fixing ring 14 to the filter cylinder 19. Then, hold the handle 8 and place the top cover 7 on the filter barrel 1. After adjusting the filter barrel 1 to a suitable position, place the locking rod 5 into the groove of the sleeve 6. Then, press down on the connecting plate 4 to make the locking rod 5 and the connecting plate 4 parallel to each other, thus fixing the filter barrel 1 and the top cover 7. With the action of the washer 21, the filter barrel 1 and the top cover 7 can be fixed more tightly.
