Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, specifically to a cleaning device for tannin purification. Background Technology

[0002] Tannins are polyphenolic compounds that are widely found in plants and have important applications in the food, pharmaceutical, cosmetic and leather industries. The tannin purification process usually includes the following main steps: extraction, preliminary purification, further purification and refining. After each tannin purification, tannins and other impurities will remain on the chromatography column, which needs to be cleaned immediately.

[0003] However, if the residues adhering to the inner wall of the chromatography column are not cleaned in time during use, it will lead to problems such as decreased column efficiency and cross-contamination, affecting the subsequent purification effect. Traditional chromatography column cleaning methods mostly rely on manual wiping, which is not only inefficient, but also difficult to ensure the comprehensiveness and uniformity of cleaning. Especially for some hard-to-reach areas on the inner wall of the chromatography column, manual cleaning often cannot achieve the ideal cleaning effect. Summary of the Invention

[0004] The purpose of this invention is to provide a cleaning device for tannin purification, so as to solve the problem mentioned in the background art: the residues adhering to the inner wall of the chromatography column after use are difficult to scrape off.

[0005] To solve the above-mentioned technical problems, this utility model provides a cleaning device for tannin purification, including a base plate. A chromatography column is provided on one side of the upper surface of the base plate, and the chromatography column is provided with an installation mechanism. A cleaning mechanism is provided on the other side of the upper surface of the base plate. The cleaning mechanism includes two fixed plates symmetrically arranged at the front and rear ends of the base plate. A rotating column is rotatably connected to the inner side wall of the fixed plate. A first rotating handle is installed on the outer side wall of one of the fixed plates. The first rotating handle is fixedly connected to the rotating column. A first gear is fixedly sleeved on the rotating column. A rack is provided on the upper surface of the base plate. The rack meshes with the first gear. A connecting plate is fixedly installed at one end of the rack near the center of the base plate. A second gear and a third gear are rotatably connected to the side of the connecting plate near the chromatography column. There are eight second gears, which mesh with the four sides of the third gear. A cleaning brush is fixedly connected to the side of the second gear away from the connecting plate. A third rotating handle is installed on the side of the connecting plate away from the cleaning brush. The third rotating handle is fixedly connected to the third gear.

[0006] Furthermore, the mounting mechanism includes a mounting column mounted on the upper surface of the base plate, two connecting strips symmetrically mounted on the side of the mounting column near the cleaning brush, the opposite sides of the connecting strips being rotatably connected to the lower end of the chromatography column, a winding roller mounted on the top of the side of the mounting column away from the connecting strips, a tension band wound around the winding roller, the other end of the tension band being fixedly connected to the upper end of the chromatography column, and a second rotating handle mounted on the winding roller.

[0007] Furthermore, the mounting column is provided with a limiting mechanism, which includes a limiting groove opened on the upper surface of the mounting column, a slider slidably connected in the limiting groove, the tension band being located below the slider and between the inner bottom wall of the limiting groove, a U-shaped frame installed on the upper surface of the mounting column, the U-shaped frame having a threaded hole, a threaded handle installed in the threaded hole, and the bottom end of the threaded handle being rotatably connected to the slider.

[0008] Furthermore, a pulley is installed on the top of the mounting column near the chromatography column, and the tensioning band is tumblingly connected to the pulley.

[0009] Furthermore, a slide is mounted on the upper surface of the base plate, and the inner wall of the slide is adapted to the rack.

[0010] Furthermore, casters are installed at the four corners of the bottom of the base plate.

[0011] Furthermore, the cleaning end of the cleaning brush is made of polypropylene, and the tensioning band is made of polytetrafluoroethylene.

[0012] Furthermore, the cleaning brush adopts a stepped bristle design.

[0013] Furthermore, the base plate is equipped with a drainage net, and the mesh holes of the drainage net are square in shape.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model moves the rack by rotating the first rotating handle, so that the connecting plate is close to the chromatography column. Then, rotating the third rotating handle drives the third gear and eight second gears to rotate, so that the cleaning brush rotates around its own axis, thereby effectively scraping off the tannins and other impurities remaining on the inner wall of the chromatography column, ensuring the cleanliness of the chromatography column, and improving the effect and purity of subsequent tannin purification.

[0015] 2. This utility model, through the installation mechanism, allows operators to rotate the winding roller by rotating the second rotating handle, releasing or tightening the tension belt. Combined with the rotating connection between the connecting strip and the lower end of the chromatography column, the tilt angle of the chromatography column can be flexibly adjusted to meet the diverse needs of different tannin samples and purification processes for the column angle. This enhances the versatility and applicability of the device, and improves the effect and quality of tannin purification. When the chromatography column is adjusted to the appropriate angle, tightening the threaded handle pushes the slider down into the limiting groove, pressing the tension belt and fixing it between the bottom wall of the limiting groove and the slider, thus achieving stable positioning of the chromatography column. This positioning method ensures that the chromatography column remains stable during the purification process, avoiding shaking or displacement due to external factors, ensuring the stability and reliability of the purification process, and improving the quality and efficiency of tannin purification.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-7 This utility model provides a technical solution: (See attached document) Figure 1 , Figure 3 and Figure 5 As shown, a cleaning device for tannin purification includes a base plate 1. A chromatography column 4 is mounted on one side of the upper surface of the base plate 1, and the chromatography column 4 is equipped with a mounting mechanism. A cleaning mechanism is mounted on the other side of the upper surface of the base plate 1. The cleaning mechanism includes two fixed plates 5 symmetrically arranged at the front and rear ends of the base plate 1. A rotating column 6 is rotatably connected to the inner side wall of the fixed plate 5. A first rotating handle 7 is mounted on the outer side wall of one of the fixed plates 5. The first rotating handle 7 is fixedly connected to the rotating column 6. A first gear 8 is fixedly sleeved on the rotating column 6. The upper surface of the base plate 1 is provided with teeth. The rack 10 meshes with the first gear 8. A connecting plate 11 is fixedly installed at one end of the rack 10 near the center of the base plate 1. A second gear 21 and a third gear 22 are rotatably connected to the side of the connecting plate 11 near the chromatography column 4. There are eight second gears 21, which mesh with the three gears 22 around the perimeter. A cleaning brush 12 is fixedly connected to the side of the second gear 21 away from the connecting plate 11. A third rotating handle 20 is installed on the side of the connecting plate 11 away from the cleaning brush 12. The third rotating handle 20 is fixedly connected to the third gear 22.

[0020] In the specific implementation process, when it is necessary to clean the chromatography column 4 in the tannin purification device, the operator can first rotate the first rotating handle 7. The first rotating handle 7 will drive the rotating column 6 to rotate. The rotation of the rotating column 6 will drive the first gear 8 to rotate, which in turn will drive the rack 10 to move linearly on the base plate 1. The movement of the rack 10 will drive the connecting plate 11 to move, so that the connecting plate 11 is close to the chromatography column 4. When the connecting plate 11 moves to the appropriate position, the operator can rotate the third rotating handle 20. Because the third rotating handle 20 is fixedly connected to the third gear 22, rotating the third rotating handle 20 will drive the third gear 22 to rotate. The rotation of the third gear 22 will drive the eight second gears 21 to rotate simultaneously. The rotation of the second gears 21 will drive the cleaning brushes 12 to rotate. Each cleaning brush 12 will rotate around its own axis to scrape off the impurities on the inner wall of the chromatography column 4. After cleaning is completed, the first rotating handle 7 can be rotated in the opposite direction to move the connecting plate 11 away from the chromatography column 4, thus completing the cleaning work.

[0021] It should be noted that the second gears 21 are evenly distributed around the third gear 22. When the third rotating handle 20 is rotated to drive the third gear 22 to rotate, the eight second gears 21 will rotate simultaneously, thereby driving the eight cleaning brushes 12 to rotate around their own axes. This allows the cleaning brushes 12 to clean the inner wall of the chromatography column 4 from multiple directions, forming a "surrounding" cleaning mode. For some hard-to-reach areas on the inner wall of the chromatography column 4, such as corners or curved parts, the cleaning brushes 12 in different positions can cooperate with each other to scrape from different angles, ensuring that the deposits in these areas can also be effectively cleaned.

[0022] See Figure 2 , Figure 4 and Figure 6 As shown, the installation mechanism includes an installation column 2, two connecting strips 3 symmetrically installed on the side of the installation column 2 near the cleaning brush 12, the opposite sides of the connecting strips 3 being rotatably connected to the lower end of the chromatography column 4, a winding roller 15 installed on the top of the side of the installation column 2 away from the connecting strips 3, a tension band 19 wound on the winding roller 15, the other end of the tension band 19 being fixedly connected to the upper end of the chromatography column 4, a second rotating handle 14 installed on the winding roller 15, a limiting mechanism provided on the installation column 2, the limiting mechanism including a limiting groove opened on the upper surface of the installation column 2, a slider 23 slidably connected in the limiting groove, the tension band 19 being located below the slider 23 and between the inner bottom wall of the limiting groove, a U-shaped frame 16 installed on the upper surface of the installation column 2, the U-shaped frame 16 having a threaded hole, a threaded handle 17 installed in the threaded hole, the bottom end of the threaded handle 17 being rotatably connected to the slider 23, a drainage net 24 installed on the base plate 1, the mesh holes of the drainage net 24 being square in shape.

[0023] In the specific implementation process, the operator first drives the winding roller 15 to rotate by rotating the second rotating handle 14, releasing or tightening the tension band 19 to adjust the tilt angle of the chromatography column 4. When adjusted to the appropriate position, the threaded handle 17 is tightened, pushing the slider 23 to move down in the limiting groove, pressing the tension band 19, and fixing it between the bottom wall of the limiting groove and the slider 23, thereby achieving stable positioning of the chromatography column 4. At the same time, flexible angle adjustment can be achieved through the rotating connection between the connecting strip 3 and the lower end of the chromatography column 4. The rapid angle adjustment of the chromatography column 4 is achieved through the cooperation of the winding roller 15 and the tension band 19, and the limiting mechanism of the slider 23 and the threaded handle 17 ensures that it is firmly fixed, so that the chromatography column 4 remains stable during the purification process, which facilitates the subsequent alignment and cleaning of the cleaning brush 12.

[0024] It should be noted that in the cleaning mechanism, rotating the first rotating handle 7 drives the rotating column 6 and the first gear 8 to rotate, which in turn causes the rack 10 to move linearly on the base plate 1, moving the connecting plate 11 closer to or further away from the chromatography column 4. This design allows the operator to precisely adjust the distance between the cleaning brush 12 and the chromatography column 4 according to the actual situation. Before cleaning, the operator moves the connecting plate 11 to a suitable position to ensure that the cleaning brush 12 can fit tightly against the inner wall of the chromatography column 4. Regardless of the installation angle or initial position of the chromatography column 4, effective contact can be achieved, thus providing a basis for comprehensive cleaning. The chromatography column 4 can be angled through the installation mechanism. When cleaning the chromatography column 4, as the connecting plate 11 moves, the cleaning brush 12 can clean the inner wall of the chromatography column 4 from different angles. Even if the chromatography column 4 is tilted, the cleaning brush 12 can cover all parts of the inner wall of the chromatography column 4 with the cooperation of its own rotation and the movement of the connecting plate 11, ensuring comprehensive cleaning.

[0025] While the cleaning brush 12 is rotating, a suitable rinsing solution, such as purified water or a specific cleaning solvent, can be sprayed through the inlet of the chromatography column 4 to rinse the inner wall. Under the combined action of gravity and the rotation of the cleaning brush 12, the rinsing solution can better wash away the scraped-off deposits, preventing them from accumulating inside the chromatography column 4. The operator can control the injection speed and volume of the rinsing solution according to the cleaning situation. After the initial cleaning and rinsing, if it is determined that there are still many impurities remaining on the inner wall of the chromatography column 4, the operation can be repeated. Rotate the first rotating handle 7 in the opposite direction to move the connecting plate 11 away from the chromatography column 4, then rotate the first rotating handle 7 again to move the connecting plate 11 closer to the chromatography column 4. Then rotate the third rotating handle 20 again to rotate the cleaning brush 12, and at the same time inject the rinsing solution again for rinsing. Repeat the above cleaning and rinsing process. The process continues until the impurities on the inner wall of the chromatography column 4 are basically removed. After repeated cleaning and rinsing, if it is deemed that the residual cleaning solvent and other substances on the inner wall of the chromatography column 4 need to be further removed, a final purified water rinsing step is performed. The rinsing solution is replaced with purified water. Following the previous operation method, the first rotating handle 7 is rotated to bring the connecting plate 11 closer to the chromatography column 4, and the third rotating handle 20 is rotated to drive the cleaning brush 12 to rotate. At the same time, purified water is injected to rinse the inner wall of the chromatography column 4. After completing one purified water rinsing, the first rotating handle 7 is rotated in the opposite direction to move the connecting plate 11 away from the chromatography column 4. The above purified water cleaning and rinsing operation is then repeated 2-3 times to ensure that the inner wall of the chromatography column 4 is thoroughly rinsed. After cleaning, the first rotating handle 7 can be rotated in the opposite direction to move the connecting plate 11 away from the chromatography column 4 to complete the cleaning work.

[0026] See Figure 1 , Figure 2 and Figure 7As shown, a pulley 18 is installed on the top of the side of the mounting column 2 near the chromatography column 4. The tension band 19 is tumblingly connected to the pulley 18. A slide 9 is installed on the upper surface of the base plate 1. The inner wall of the slide 9 is adapted to the rack 10. Universal wheels 13 are installed at the four corners of the bottom of the base plate 1. The cleaning end of the cleaning brush 12 is made of polypropylene, and the tension band 19 is made of polytetrafluoroethylene. When the cleaning brush 12 is in contact with the chromatography column 4, the maximum sliding range of the rack 10 does not exceed the length range of the slide 9. The cleaning brush adopts a stepped bristle design.

[0027] In the specific implementation process, the operator can easily move the entire device to the working position through the universal wheels 13 at the bottom of the base plate 1. When adjusting the angle of the chromatography column 4, the tension band 19 will slide smoothly along the pulley 18 at the top of the mounting column 2, effectively reducing friction loss. When the cleaning mechanism is running, the rack 10 moves smoothly under the guide limit of the slide 9, ensuring that the cleaning brush 12 always maintains stable contact with the chromatography column 4, and the sliding range of the rack 10 is strictly limited within the length of the slide 9 to prevent the mechanism from dislodging. The cleaning brush 12 adopts a stepped bristle design. The length of the main bristles is adapted to the straight section of the column, and the length of the secondary bristles is increased by 5-8mm. They are radially distributed at the root of the brush body and can reach into corners and gaps. The bristles of the cleaning brush 12 made of polypropylene have excellent chemical corrosion resistance, while the tension band 19 made of polytetrafluoroethylene has both high strength and low friction characteristics, which together ensure the reliability and durability during the cleaning process.

[0028] Working principle: Step 1: The operator first rotates the second rotating handle 14 to drive the winding roller 15 to rotate, releasing or tightening the tension band 19. The tension band 19 slides smoothly along the pulley 18 at the top of the mounting column 2 to adjust the tilt angle of the chromatography column 4. When adjusted to the appropriate position, tighten the threaded handle 17 to push the slider 23 down in the limiting groove, pressing the tension band 19 to fix it between the bottom wall of the limiting groove and the slider 23, thus achieving a stable limiting position of the chromatography column 4. Through the rotating connection between the connecting strip 3 and the lower end of the chromatography column 4, the cooperation between the winding roller 15 and the tension band 19, and the limiting mechanism between the slider 23 and the threaded handle 17, the chromatography column 4 can be flexibly adjusted, quickly adjusted, and securely fixed, facilitating the subsequent alignment and cleaning of the cleaning brush 12.

[0029] Step Two: When cleaning the chromatography column 4 in the tannin purification apparatus is required, the operator first rotates the first rotating handle 7. The first rotating handle 7 drives the rotating column 6 to rotate, which in turn drives the first gear 8 to rotate, thereby driving the rack 10 to move linearly on the base plate 1. The rack 10 moves smoothly under the guidance and limit of the slide 9, and its maximum sliding range does not exceed the length range of the slide 9. The movement of the rack 10 drives the connecting plate 11 to move, so that the connecting plate 11 is close to the chromatography column 4. After the connecting plate 11 moves to the appropriate position, the operator rotates the third rotating handle 20. The third rotating handle 20 drives the third gear 22 to rotate, and the third gear 22 drives the eight second gears 21, which are equally spaced around it, to rotate simultaneously. The second gears 21 drive the cleaning brush 12 to rotate around its own axis, thereby achieving a comprehensive cleaning of the inner wall of the chromatography column 4 and forming an "encircling" cleaning mode. The cleaning brushes 12 in different positions cooperate with each other to scrape some hard-to-reach areas of the inner wall of the chromatography column 4 from different angles, such as corners or curved parts. After cleaning, rotate the first rotating handle 7 in the opposite direction to move the connecting plate 11 away from the chromatography column 4.

[0030] Step 3: While the cleaning brush 12 is rotating, a suitable rinsing solution, such as purified water or a specific cleaning solvent, can be sprayed through the inlet of the chromatography column 4 to rinse the inner wall. Under the combined action of gravity and the rotation of the cleaning brush 12, the rinsing solution washes away the scraped-off deposits, preventing them from accumulating inside the chromatography column 4. The operator can control the injection speed and amount of rinsing solution according to the cleaning situation. Then, rotate the first rotating handle 7 to disengage the cleaning mechanism. Next, rotate the second rotating handle 14 to adjust the angle of the chromatography column 4 downward. The bottom plate 1 is equipped with a drainage net 24 at the corresponding position below the chromatography column 4 to discharge the waste mixed with the cleaning solution from the drainage net 24. The operator can easily move the entire device to the working position using the casters 13 installed at the four corners of the bottom of the bottom plate 1. In addition, the cleaning brush 12 adopts a stepped bristle design. The length of the main bristles is adapted to the straight section of the column, and the length of the secondary bristles is increased by 5-8mm. They are radially distributed at the root of the brush body and can reach into corners and crevices. The bristles of the cleaning brush 12 made of polypropylene have excellent chemical corrosion resistance, and the tensioning band 19 made of polytetrafluoroethylene has both high strength and low friction characteristics, which together ensure the reliability and durability during the cleaning process.
