Description
Technical Field
[0001] This utility model relates to the field of resin production technology, and in particular to a natural filtration device for diluting unsaturated resin. Background Technology
[0002] In the chemical and composite materials industries, the unsaturated resin dilution process is a crucial step in the production of unsaturated polyester resins, fiberglass products, and other similar products. During the unsaturated resin dilution process, a natural filtration device is needed to separate the solid and liquid components of the mixed solution, removing impurities to ensure the purity of the resin solution and thus guarantee the quality and performance of downstream products. This natural filtration device uses physical interception to separate insoluble impurities generated during resin dilution from the solution, ensuring that the filtered pure resin solution meets the requirements of subsequent processing.
[0003] Traditional filtration devices typically rely solely on filter screens to intercept impurities, lacking an effective self-cleaning mechanism. Over prolonged use, a large amount of impurities easily accumulates on the filter screen surface, leading to clogging and a significant decrease in filtration efficiency. When the filter screen becomes clogged, frequent shutdowns for manual cleaning are necessary, consuming substantial manpower and time. Furthermore, frequent disassembly and cleaning accelerates filter screen wear, shortens its lifespan, and increases replacement costs. In addition, the components used for cleaning the filter screen in existing devices, after long-term use, wear and tear makes it difficult to maintain a tight fit with the filter screen, gradually weakening the cleaning effect and making it difficult to maintain stable filtration performance. This fails to meet the continuous requirements for the filtration efficiency and quality of unsaturated resin in industrial production. Therefore, a natural filtration device using diluted unsaturated resin is proposed. Summary of the Invention
[0004] To overcome the above shortcomings, this utility model provides a natural filtration device using unsaturated resin dilution, aiming to improve the problem in the prior art where the components used for cleaning the filter screen are difficult to maintain a tight fit with the filter screen after long-term use due to wear, resulting in a gradual weakening of the cleaning effect and difficulty in maintaining stable filtration performance.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a natural filtration device for diluting unsaturated resin, comprising a filter box, a filter screen fixedly connected inside the filter box, a protective cover fixedly connected to the top of the filter box, a reciprocating sliding assembly disposed inside the protective cover, a driving assembly disposed on the top of the protective cover, a guide rod fixedly connected to the inner wall of the filter box, two cleaning assemblies slidably connected to the outer wall of the guide rod, three rotating shafts rotatably connected to the inner wall of the filter box, a circular gear fixedly connected to the top of the middle rotating shaft, and a striking assembly disposed on the outer wall of the rotating shaft;

[0021] This utility model has the following beneficial effects:
[0022] 1. In this utility model, the cleaning component and the striking component constitute a dual self-cleaning mechanism. When impurities accumulate on the filter screen surface and affect the filtration efficiency, the motor drives the half gear to rotate. Through the transmission of the internal gear ring, rack plate and spur gear, the scraper in the cleaning component slides back and forth along the filter screen surface to scrape off the surface impurities. At the same time, the cam on the rotating shaft periodically strikes the back of the filter screen, causing stubborn impurities to fall off.

Even if the scraper is worn, it can maintain a tight fit with the filter screen through the automatic compensation of the spring, which significantly extends the service life of the filter screen and reduces the frequency of manual cleaning and the cost of filter screen replacement.

[0033] Reference Figures 1-3 This utility model provides an embodiment of a natural filtration device for diluting unsaturated resin, comprising a filter box 1, with a filter screen 3 fixedly connected inside the filter box 1. The filter screen 3, as the core filtration component, can intercept impurities generated during the dilution process of unsaturated resin, achieving solid-liquid separation. A protective cover 2 is fixedly connected to the top of the filter box 1, serving a protective function to prevent external dust and debris from entering the device, while also providing an installation support environment for internal components. A reciprocating sliding component is provided inside the protective cover 2, enabling periodic reciprocating motion and providing a power transmission basis for driving other components. A drive component is provided at the top of the protective cover 2, serving as the power source for the entire device's movement and providing driving power for the reciprocating sliding component, etc. A series of components are fixedly connected to the inner wall of the filter box 1. Guide rod 15 provides guidance for the sliding of the cleaning components, ensuring the stability and accuracy of the cleaning components' movement. Two cleaning components are slidably connected to the outer wall of guide rod 15. The cleaning components can clean the filter screen 3, preventing impurities from clogging the filter screen 3 and ensuring the filtration efficiency and service life of the filter screen 3. Three rotating shafts 17 are rotatably connected to the inner wall of the filter box 1. The rotating shafts 17 serve as transmission components, transmitting power and driving other components to rotate. A spur gear 18 is fixedly connected to the top of the middle rotating shaft 17. The spur gear 18 meshes with the rack plate 16, converting the linear motion of the reciprocating sliding components into the rotation of the rotating shaft 17, thus realizing the conversion of motion form. A striking component is provided on the outer wall of the rotating shaft 17. The striking component knocks off the impurities attached to the filter screen 3 by striking it, further improving the cleaning effect.
[0034] Reference Figure 4 The reciprocating sliding assembly includes a guide plate 6, which is fixedly connected to the inner wall of the protective cover 2. A slider 7 is slidably connected to the inner wall of the guide plate 6, providing a sliding track for the slider 7 to ensure that the slider 7 slides in a predetermined direction. An internal gear ring 8 is fixedly connected to the side of the slider 7 away from the guide plate 6. The internal gear ring 8 meshes with a half gear 5 and achieves reciprocating motion under the action of the drive assembly. A rack plate 16 is fixedly connected to the side of the internal gear ring 8 away from the slider 7. The rack plate 16 meshes with a spur gear 18 and transmits the reciprocating motion of the internal gear ring 8 to the spur gear 18. Two connecting rods 9 are fixedly connected to the bottom of the internal gear ring 8. The connecting rods 9 are used to connect the internal gear ring 8 and the cleaning assembly to transmit motion and power.
[0035] Reference Figure 4 The drive component includes a motor 4, which is fixedly connected to the top of the protective cover 2. The motor 4 serves as a power source, providing stable power output for the operation of the device. A half gear 5 is fixedly connected to the output end of the motor 4. The half gear 5 meshes with the internal gear ring 8, converting the rotational motion of the motor 4 into the reciprocating linear motion of the internal gear ring 8.
[0036] Reference Figure 5 The cleaning assembly includes two mounting plates 10, which are slidably connected to the outer wall of the guide rod 15. The mounting plates 10 are used to install other components and slide under the guidance of the guide rod 15. A connecting plate 11 is slidably connected to the inner wall of the mounting plate 10. The connecting plate 11 can slide within the mounting plate 10 and, in conjunction with the spring 14, achieves elastic extension and contraction to adapt to different cleaning needs. A limiting plate 12 is fixedly connected to one side of the connecting plate 11. The limiting plate 12 is used to limit the sliding range of the connecting plate 11 to ensure the normal operation of the cleaning assembly. A scraper 13 is fixedly connected to the other side of the connecting plate 11. The scraper 13 is in contact with the filter screen 3 and can scrape off impurities attached to the surface of the filter screen 3. A spring 14 is fixedly connected to the side of the limiting plate 12 away from the connecting plate 11. The spring 14 provides elastic pressure to the scraper 13, so that it always keeps in contact with the filter screen 3 to ensure the cleaning effect. The top of the mounting plate 10 is fixedly connected to the bottom of the connecting rod 9. The connecting rod 9 receives the power transmitted by the reciprocating sliding assembly and drives the cleaning assembly to move.
[0037] Reference Figure 6 The striking component includes multiple cams 19, which are fixedly connected to the outer wall of the rotating shaft 17. The cams 19 rotate with the rotating shaft 17 and periodically strike the filter screen 3 with their protruding parts, causing impurities on the filter screen 3 to fall off, thus assisting the cleaning component in improving the cleaning effect.
[0038] Reference Figure 4 The top of the filter box 1 has two sliding grooves 21. The outer wall of the connecting rod 9 is slidably connected to the inner wall of the sliding groove 21. The sliding groove 21 provides guidance and limit for the sliding of the connecting rod 9, ensuring the stability and accuracy of the reciprocating sliding component movement.
[0039] Reference Figure 2 and Figure 3 The side of the spring 14 away from the limiting plate 12 is fixedly connected to the inner wall of the mounting plate 10, ensuring that the spring 14 can provide stable elastic pressure to the scraper 13. The scraper 13 and the filter screen 3 are in contact with each other, ensuring that the scraper 13 can effectively scrape off impurities from the surface of the filter screen 3. The protruding part of the cam 19 is in contact with the other side of the filter screen 3, so that the cam 19 can effectively strike the filter screen 3 to assist in cleaning.
[0040] Reference Figure 6A pulley 20 is fixedly connected to the outer wall of the rotating shaft 17. A belt is sleeved between two pulleys 20 at the same level. Through the transmission of the pulleys 20 and the belt, the power transmission between the three rotating shafts 17 is realized, ensuring that the striking components work synchronously.
[0041] Reference Figures 1-3 The filter box 1 has an inlet at the top, which is used to introduce the unsaturated resin diluted mixture into the filter box 1 to start the filtration process. The filter box 1 has an outlet at the bottom of the outer wall, which is used to discharge the pure liquid after filtration by the filter screen 3 to complete the entire filtration process.
[0042] Working principle: When unsaturated resin needs to be filtered, the resin is poured into the filter box 1 through the feed port at the top of the filter box 1. Subsequently, the resin is drawn and conveyed by other external components and passes through the filter screen 3. The filtered impurities will adhere to the filter screen 3. After long-term use, the surface of the filter screen 3 will become clogged, thus affecting the filtration efficiency. At this time, during the filtration process, the motor 4 can be energized. When the motor 4 is energized, it will rotate. When the motor 4 rotates, it will drive the half gear 5 on its output end to rotate. The rotation of the half gear 5 will drive the internal gear ring 8 through meshing. The internal gear ring 8 reciprocates linearly along the guide plate 6. When the internal gear ring 8 reciprocates linearly, it drives the two mounting plates 10 to reciprocate linearly along the guide rod 15 via the two connecting rods 9, thereby cleaning the surface of the filter screen 3. At the same time, the linear reciprocating motion of the internal gear ring 8 also drives the rack plate 16 to reciprocate linearly. Since the rack plate 16 meshes with the spur gear 18, when the rack plate 16 reciprocates linearly, it drives the spur gear 18 to rotate, which in turn drives the rotating shaft 17 to rotate. The cam 19 on the rotating shaft 17 strikes the filter screen 3, increasing the cleaning efficiency of the filter screen 3.
[0043] During the reciprocating sliding of the mounting plate 10, the scraper 13 connected by the connecting plate 11 will continuously wear during the reciprocating movement. At this time, under the push of the spring 14, the limiting plate 12 will be pushed to slide, and the scraper 13 will be driven to slide through the connecting plate 11, so that the scraper 13 always keeps in contact with the scraper 13, thus extending the service life of the scraper 13.
[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
