Description

Technical Field

[0001] The invention relates to the technical field of dirt cleaning, in particular to a mixing kettle cleaning device for preparing veratrone. Background Art

[0002] Veratrone, chemically known as 3,4-dimethoxyphenylpropiotone, also known as veratryl acetone, is a chemical substance. Veratrone is widely used in the pharmaceutical field, mainly used to produce antihypertensive drug methyldopa, tranquilizer drug schisandra chinensis acetone, and anti-Parkinson's disease drug levodopa methyl ester hydrochloride. The preparation process of veratrone requires the use of a mixing kettle to provide mixing and reaction treatment. The mixing kettle will accumulate various residues, dirt and microorganisms during long-term use. These residues will not only affect the purity and quality of the product, but may also cause equipment corrosion and blockage, thereby reducing production efficiency. Regular cleaning of the mixing kettle can ensure that the products produced meet quality standards and reduce rework and waste caused by quality problems.

[0003] ‌The prior art mixing kettle cleaning device used for the preparation of veratrol directly completes the cleaning by flushing with high-pressure water, but the cleaning power of this solution is weak, and the whole process requires long-term manual operation, which is difficult to clean and requires a lot of human resources. On the other hand, although it can improve the cleaning performance and reduce the labor intensity of workers by building a special cleaning structure and inserting it into the inner wall of the mixing kettle for cleaning, it is difficult to match a large range of mixing kettles of different sizes, the scope of application is fixed, and the flexibility is insufficient. In addition, the washing structure needs to be taken out of the entire device before it can be replaced or cleaned, and the washing structure cannot be self-cleaned in the middle of a single cleaning of the mixing kettle. Therefore, the cleaning effect will continue to weaken in the later stage of each cleaning process of the mixing kettle. Summary of the invention

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0028] See also Figures 1 to 7 The present invention provides the following technical solutions: a cleaning device for a mixing kettle for preparing veratrol, comprising a cleaning device body and a mixing kettle body 1, wherein the cleaning device body comprises a cleaning bracket, a driving mechanism 4, an edge scrubbing mechanism 5 and a bottom scraping mechanism 6, wherein the cleaning bracket comprises a first cleaning bracket 2 and a second cleaning bracket 3, and a telescopic rod 23 is welded to the end of the first cleaning bracket 2, and the end of the telescopic rod 23 is embedded in the interior of the second cleaning bracket 3, and the bottom scraping mechanism 6 is sleeved on the surface of the telescopic rod 23, and the ends of the first cleaning bracket 2 and the second cleaning bracket 3 are both installed with end plates 7, The surface of the end plate 7 is screwed with a driving mechanism 4, and the surfaces of the first cleaning bracket 2 and the second cleaning bracket 3 are interspersed with edge scrubbing mechanisms 5. The surface of the edge scrubbing mechanism 5 is keyed to a driven gear 21, and the driving mechanism 4 is connected to the driven gear 21 for transmission. Each of the end plates 7 is pressed on the top of the mixing kettle body 1, and the central axis of the bottom scraping mechanism 6 coincides with the central axis of the mixing kettle body 1. The side of the edge scrubbing mechanism 5 is in contact with the inner side wall of the mixing kettle body 1. The cleaning device is used to clean the inner side of the mixing kettle body 1 used in the preparation process of veratrol.

[0029] When the present invention is used, the top cover of the mixing kettle body 1 to be cleaned is removed, and then the entire cleaning device can be embedded and placed inside the mixing kettle body 1. Figure 1 As shown, the extrusion bolts 12 on the lower hanging plates 11 at both ends and the first screw 8 are controlled to ensure that the edge scrubbing mechanism 5 and the driving wheel 10 are respectively pressed against the inner wall and outer surface area of ​​the mixing kettle body 1 with a relatively high pressure, and then the second screw 19 is controlled to adjust the transmission pressure of the toothed belt 14. After all the adjustments are completed, the driving mechanism 4 at the end of each cleaning bracket can be started, and the entire cleaning device can be controlled to rotate with the help of the driving mechanism 4. At this time, the edge scrubbing mechanism 5 on the inner side of the cleaning bracket can be driven to rotate along the inner wall of the mixing kettle body 1, and the cleaning effect of the inner side wall part of the mixing kettle body 1 can be achieved during the rotation process. At the same time, the first cleaning bracket 2 and the second cleaning bracket 3 will synchronously drive the middle bottom scraping mechanism 6 to rotate, and the bottom scraping mechanism 6 is used to scrape and clean the bottom end area of ​​the inner wall of the mixing kettle body 1, so as to finally achieve the purpose of cleaning a large area inside the mixing kettle body 1.

[0030] In this embodiment, the driving mechanism 4 includes a motor 9 and a tensioning gear 15. The housing of the motor 9 is screwed to the surface of the end plate 7. A toothed belt 14 is provided on the output shaft of the motor 9 through a gear sleeve. A first screw 8 is inserted into the outer side of the end plate 7. The end of the first screw 8 is embedded in the corresponding first cleaning bracket 2 or second cleaning bracket 3. A driving wheel 10 is screwed to the end of the output shaft of the motor 9. The side of the driving wheel 10 is against the outer surface of the mixing kettle body 1. A lower hanging plate 11 is integrally formed at the bottom of the end of the first cleaning bracket 2 and the second cleaning bracket 3. An extrusion bolt 12 is inserted into the surface of the lower hanging plate 11. A ball 13 is embedded in the end of the extrusion bolt 12. An extension column 17 is integrally formed on one side of the end of the first cleaning bracket 2 and the second cleaning bracket 3. A slide groove 18 is provided inside the extension column 17. A second screw 19 is inserted inside the slide groove 18. The slide block 16 is embedded in the slide groove 18, and the top of the slide block 16 is connected to the tensioning gear 15 through the shaft. The tensioning gear 15 is meshed with the toothed belt 14. The second screw 19 is used to control the slide block 16 to move along the inside of the slide groove 18. The driving mechanism 4 at the top can control the entire cleaning device to rotate along the top of the mixing kettle body 1, which improves the cleaning strength and reduces the labor intensity of workers. Except for the replaceable scraper 29 at the bottom, the rest of the structure can be applied to mixing kettles of different sizes, and even if the wall thickness of different mixing kettle bodies 1 is different, it can still ensure the rotation stability of the entire device and the pressure of the edge washing mechanism 5 remains fixed.

[0031] Specifically, since a gap is provided between the cleaning bracket and the end plate 7, and the gap is connected through the first screw 8, after rotating the extrusion bolt 12 on the lower hanging plate 11, the ball 13 at the end is pressed against the inner wall of the mixing kettle body 1, and the cleaning bracket can be pulled toward the middle to push it, so the driving wheel 10 under the end plate 7 can be pressed against the outer surface of the mixing kettle body 1 under high pressure, and based on the pressure, it is ensured that the driving wheel 10 can drive the entire cleaning device to rotate around the mixing kettle body 1. In this process, the rotation of the first screw 8 is also controlled to control the distance between the driving wheels 10 on both sides. With the help of this process, it is only used for mixing kettle bodies 1 of different diameters, and the extrusion bolt 12 cooperates with the driving wheel 10 to be suitable for extrusion of mixing kettle bodies 1 of different wall thicknesses.

[0032] After the adjustment is completed, the motor 9 on the top can be started. The motor 9 rotates to drive the toothed belt 14 to operate, and then the tensioning gear 15 and the driven gear 21 are driven to rotate. The driven gear 21 can drive the entire edge washing mechanism 5 to rotate, and the edge washing mechanism 5 is used to achieve the purpose of cleaning the inner wall and side wall of the mixing kettle body 1. After the position of the cleaning bracket and the driving wheel 10 is adjusted by the above-mentioned extrusion bolt 12 in cooperation with the first screw 8, the distance between the motor 9 and the driven gear 21 will change. At this time, the second screw 19 can be rotated to control the movement of the sliding block 16, and the position of the tensioning gear 15 can be adjusted according to the change in the distance between the above-mentioned motor 9 and the driven gear 21, ensuring that the toothed belt 14 can be tensioned or relaxed with the above-mentioned changes, so that it always maintains efficient transmission and does not shorten its service life.

[0033] In this embodiment, the edge scrubbing mechanism 5 includes a scrubbing sponge 31, a hollow sleeve 20 and a pull rod 32. The top of the hollow sleeve 20 passes through the surface of the first cleaning bracket 2 or the second cleaning bracket 3. A fixed top plate 30 is welded to the surface of the hollow sleeve 20. A scrubbing sponge 31 is attached to the bottom of the fixed top plate 30. A movable bottom plate 37 is attached to the bottom of the scrubbing sponge 31, and the inner side of the scrubbing sponge 31 is a hollow structure. A guide column 33 is integrally formed at the bottom of the hollow sleeve 20. A guide groove 34 is provided on the inner side of the guide column 33. The guide column 33 passes through the inside of the movable bottom plate 37, and the top of the guide column 33 is fixedly connected to the surface of the fixed top plate 30. The top of the hollow sleeve 20 is integrally formed with a docking sleeve 22, and an injection port 36 is provided on the top of the docking sleeve 22. The injection port 36 is used to inject cleaning liquid or clean water. The pull rod 32 passes through the injection port 36, the docking sleeve 22, the hollow sleeve 20 and the guide groove 34 in sequence, and a support plate 35 is welded to the end of the pull rod 32. A retaining bar 38 is integrally formed in the middle of the retaining plate 35, and the retaining bar 38 passes through the guide groove 34. A sealing disk 39 is integrally formed on the outer side of the top of the pull rod 32, and the sealing disk 39 is used to be stuck inside the injection port 36 to seal it.

[0034] Even when it is used for cleaning the mixing kettle body 1 with different wall thicknesses, after controlling the first screw 8 so that the edge washing mechanism 5 and the driving wheel 10 always press against the inner and outer walls of the mixing kettle body 1 with a fixed pressure, the second screw 19 at the rear end can also cooperate with the tensioning gear 15 to ensure that the entire driving mechanism 4 also maintains an isobaric transmission state, thereby avoiding the problem that the toothed belt 14 is too loose, resulting in a decrease in transmission efficiency, or the toothed belt 14 is too tight, resulting in a decrease in service life.

[0035] Specifically, the driven gear 21 drives the hollow sleeve 20 to rotate, thereby driving the fixed top plate 30 and the scrubbing sponge 31 at the bottom to rotate synchronously. The side of the scrubbing sponge 31 is pressed against the inner wall of the mixing kettle body 1. Therefore, after the scrubbing sponge 31 rotates, the inner wall of the mixing kettle body 1 can be cleaned. In the early stage of cleaning, the pull rod 32 is pulled upward to expose the injection port 36. The cleaning liquid can be poured into the interior of the hollow sleeve 20, and then pass through the fixed top plate 30 into the bottom guide column 33. The washing sponge 31 can be compressed and the saturated sewage can be squeezed out. In the whole cleaning process, the clean water from the outside is always injected into the mixing kettle body 1 from the top along the spray pipe.

[0036] In this embodiment, the bottom scraping mechanism 6 includes a transmission arm 26 and a scraper blade 29. A sliding sleeve 25 is welded on the top of the transmission arm 26. The sliding sleeve 25 is sleeved on the surface of the telescopic rod 23. A telescopic sleeve 24 is provided at one end of the second cleaning bracket 3. The end of the telescopic rod 23 is embedded in the inside of the telescopic sleeve 24. The scraper blade 29 is screwed to the bottom of the transmission arm 26, and the scraper blade 29 matches the size of the bottom end of the inner wall of the mixing kettle body 1. Positioning rods 27 are welded on both sides of the transmission arm 26. Positioning springs 28 are sleeved on the surface of the positioning rods 27. When applied to mixing kettle bodies 1 of different sizes, it is only necessary to clamp the cleaning brackets on both sides against the surface of the mixing kettle body 1. At this time, the process of adjusting the position of the bottom scraping mechanism 6 can be automatically completed, ensuring that the center point of the scraper blade 29 at the bottom is always at the central axis position of the mixing kettle body 1. Therefore, the arc matching the bottom with the mixing kettle body 1 can always maintain a more accurate fit scraping state.

[0037] Specifically, after the two cleaning brackets are installed, the middle telescopic rod 23 is pulled out from the inside of the telescopic sleeve 24, and the positioning springs 28 on both sides can be pressed against the middle position of the two cleaning brackets with the same thrust, thereby ensuring that the sliding sleeve 25 and the transmission arm 26 are at the middle point of the two cleaning brackets, that is, the middle position of the arc-shaped scraper 29 at the bottom is completely aligned with the middle position of the bottom of the mixing kettle body 1. After the two cleaning brackets are driven to rotate by the driving mechanism 4, the scraper 29 at the bottom can be directly driven to rotate along the bottom of the mixing kettle body 1, thereby achieving the purpose of scraping and cleaning the inner wall of the mixing kettle body 1.

[0038] The basic principles and main features of the present invention and the advantages of the present invention are shown and described above. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.

[0039] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
