[0002] A reaction vessel is a piece of equipment used in industries such as chemical, pharmaceutical, and food processing, primarily for chemical reactions, material mixing, heating, or cooling processes. It typically consists of a sealed container (the vessel body) and associated stirring mechanism, heating / cooling system, and control system. After use for certain specific applications, the inner wall of the reaction vessel needs to be cleaned to ensure cleanliness and smooth operation for the next use. Examples include applications involving high-viscosity materials, bio-fermentation, food processing, and pharmaceutical synthesis. In these cases, residues accumulate on the inner wall of the reaction vessel after use, affecting not only the purity and quality of subsequent processed products but also potentially heat transfer efficiency. To ensure cleanliness and smooth operation for the next use, thorough cleaning or scraping of the inner wall is necessary. However, existing cleaning methods generally require additional cleaning tools or equipment, making it impossible to use the reaction vessel's stirring mechanism for cleaning the inner wall, increasing cleaning difficulty and cost.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] A type of reaction vessel, such as Figures 1 to 3As shown, the apparatus includes a vessel body 1 and a stirring mechanism mounted on the vessel body 1. The stirring mechanism includes a rotating rod 2 rotatably mounted on the vessel body 1, with a stirring paddle 3 at one end of the rotating rod 2 extending into the vessel body 1. A driver 4 is mounted on the vessel body 1 to drive the rotating rod 2 to rotate. The stirring paddle 3 is horizontally mounted on the rotating rod 2, with one end fixed to the rotating rod 2 and the other end equipped with a detachable cleaning component. The vessel body 1 can be a conventional reactor body 1, and the driver 4 can be a conventional driver 4 such as a drive motor. The power supply and installation methods of the driver 4 are existing technologies. Those skilled in the art can select a suitable driver 4 according to actual needs to drive the rotating rod 2 to rotate, thereby driving the stirring paddle 3 to rotate; further details are omitted here.

[0021] The cleaning assembly includes a connecting sleeve 8 and a scraper 5. The connecting sleeve 8 has an assembly hole 11 that mates with the stirring paddle 3. The scraper 5 is slidably mounted on the connecting sleeve 8, and the sliding direction of the scraper 5 is horizontal. The connecting sleeve 8 has a detachable connector 15 at the position corresponding to the assembly hole 11. The stirring paddle 3 has a connector hole 10 that mates with the connector 15. The connecting sleeve 8 has an installation hole 12 for installing the connector 15, and the installation hole 12 communicates with the assembly hole 11. The connecting sleeve 8 also has a limiting ring 7 for sealing the installation hole 12 and for holding the scraper 5 in place. The limiting ring 7 is detachably mounted on the connecting sleeve 8.

[0022] In practical applications, the scraper component 5 is fixed on the connecting sleeve 8. By detachably installing the cleaning component on the stirring paddle 3, when the reactor needs cleaning, the operator can first open the reactor cover, then hoist the reactor cover and install the cleaning component. After reinstalling the reactor cover, the stirring mechanism can be used to drive the cleaning component to rotate, so that the scraper can scrape off the deposits on the inner wall of the reactor body 1. No additional cleaning tools and equipment are needed, which reduces the cleaning difficulty and cost of the reactor body 1 and helps to improve the utilization efficiency of the reactor.

[0023] Preferably, the limiting ring 7 and the connecting sleeve 8 are threaded together. The connecting sleeve 8 has an external thread, and the limiting ring 7 has an internal thread that mates with the external thread. In actual use, the operator can use a wrench or other tools to tighten the limiting ring 7, thereby blocking and sealing the mounting hole 12, thus limiting the insertion part 15 and ensuring that the insertion part 15 continuously and stably limits the connection between the connecting sleeve 8 and the stirring paddle 3. At the same time, the operator can also use the limiting ring 7 to press against the scraper 5, adjust the position of the scraper 5, and limit the scraper 5, ensuring that the scraper 5 can stably adhere to the inner wall of the vessel body 1 during the rotation of the stirring paddle 3, which is beneficial to improving the scraping effect of the scraper 5 on the inner wall of the vessel body 1.

[0024] Conversely, when it is necessary to disassemble and clean the components, the operator only needs to remove the limiting ring 7 first. After the limiting ring 7 releases the limiting of the connector 15, the operator can disconnect the connection between the connecting sleeve 8 and the stirring paddle 3 by removing the connector 15. Then the connecting sleeve 8 can be easily disassembled, which is very convenient.

[0025] Preferably, the scraper component 5 is provided with a sliding sleeve 6 that slides with the connecting sleeve 8. A slider 14 is provided inside the sliding sleeve 6, and a groove 13 that mates with the slider 14 is provided on the connecting sleeve 8. The limiting ring 7 limits the scraper component 5 by pressing against the sliding sleeve 6. For example, the sliding sleeve 6 is fixed to the scraper component 5, and at least two sliders 14 are evenly arranged along the circumference of the sliding sleeve 6. The grooves 13 correspond one-to-one with the sliding sleeves 6; for example, two sliders 14 can be evenly arranged, and each slider 14 is fixed to the sliding sleeve 6.

[0026] In practical applications, the sliding sleeve 6 and the connecting sleeve 8 can be slidably fitted together to allow the scraper 5 to slide on the connecting sleeve 8, making it easy for operators to disassemble and replace the scraper 5. By setting two sliders 14 along the circumference of the sliding sleeve 6, the stability of the sliding connection between the sliding sleeve 6 and the connecting sleeve 8 is improved, ensuring that the scraper can always stably scrape and clean the inner wall of the vessel 1 along with the stirring paddle 3.

[0027] In an optional embodiment, the mounting hole 12 is provided corresponding to the slide groove 13, and the mounting hole 12 communicates with the slide groove 13. By providing the mounting hole 12 corresponding to the slide groove 13, after the connector 15 passes through the mounting hole 12 and the connector hole 10 at once, the end of the connector 15 can be stored in the slide groove 13, which will not obstruct the movement of the limiting ring 7. It also makes it convenient for the operator to use tools to reach into the slide groove 13 to disassemble the connector 15, which helps to further reduce the assembly difficulty of this cleaning component.

[0028] Preferably, at least two connectors 15 are provided at intervals along the length of the connecting sleeve 8. For example, two or more connectors 15 may be provided at intervals, and the mounting holes 12 correspond one-to-one with the connectors 15. By providing at least two connectors 15 at intervals, the structural strength at the connection between the connecting sleeve 8 and the stirring paddle 3 is improved, ensuring a stable connection between the two.

[0029] Preferably, multiple insertion holes 10 are spaced apart along the length of the agitator 3. By providing multiple insertion holes 10 on the agitator 3, operators can select the appropriate insertion hole 10 for alignment and assembly according to actual needs. By adjusting the position of the connecting sleeve 8 on the agitator 3 and coordinating with the adjustment of the position of the scraper 5 on the connecting sleeve 8, the scraper 5 can better fit against the inner wall of the vessel body 1, improving the applicability of the cleaning component to different vessels 1 and the cleaning effect.

[0030] Preferably, at least two stirring paddles 3 are spaced apart along the length of the rotating rod 2, and the cleaning components are arranged one-to-one with the stirring paddles 3. The scraper components 5 of two adjacent cleaning components are detachably connected. For example, the detachable connection between two adjacent scraper components 5 can be achieved by conventional means such as bolts. By arranging two stirring paddles 3 at intervals and connecting the scraper components 5 of the cleaning components on the two stirring paddles 3, two-point limiting of the scraper components 5 is achieved, which helps to improve the stability of the scraper components 5 as they rotate with the stirring paddles 3 and increases the area that the scraper components 5 can scrape and clean, thereby improving the scraping and cleaning efficiency of the cleaning device on the inner wall of the vessel 1.

[0031] In practical applications, the scraper component 5 has a bent portion 9 at its end that can cooperate with the arc surface of the inner wall of the vessel body 1. By providing the bent portion 9 on the scraper component 5, the scraper component 5 can also achieve a good scraping and cleaning effect on the arc surface of the inner wall of the vessel body 1.

[0032] The reaction vessel described in this utility model integrates a detachable cleaning component into the stirring mechanism. The stirring mechanism itself drives the cleaning mechanism to scrape away deposits adhering to the inner wall of the vessel. This offers advantages such as good cleaning effect, ease of operation, high cleaning efficiency, and low cost, thereby improving the utilization efficiency of the reaction vessel. By adjusting the position of the connecting sleeve on the stirring paddle and, in conjunction with adjusting the position of the scraper on the connecting sleeve, the scraper can better conform to the inner wall of the vessel, improving the applicability of the cleaning component to different vessel types and its cleaning effect.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
