[0002] In industries such as chemical and pharmaceutical manufacturing, reaction vessels are common equipment used for various chemical reactions. While existing technologies, such as the reaction vessel disclosed in patent publication number CN220159968 U, have improved reaction efficiency and product quality by setting up feeding and discharging components to achieve quantitative feeding of reaction raw materials and scraping of reaction products, some shortcomings still exist. For example, during the reaction process, reaction products easily adhere to the inner wall of the reaction vessel, which not only affects the cleanliness of the vessel but may also lead to a decrease in the reaction rate and even affect the quality of subsequent reactions. Furthermore, existing reaction vessels often struggle to achieve uniform stirring of materials during the stirring process, especially when there is a large amount of material or the material viscosity is high, resulting in poor stirring and potentially incomplete reactions.

[0003] Therefore, how to further improve the cleaning and stirring effects of the reactor has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0014] (III) Beneficial Effects

[0015] This utility model provides a reaction vessel device, which has the following beneficial effects:

[0016] 1. By incorporating cleaning components, including a cleaning scraper and a movable plate, the stirring blades drive the movable plate, which in turn rotates clockwise, to scrape the inner wall of the reactor, effectively removing reaction products adhering to it and significantly improving the cleaning effect. This design not only improves the cleanliness of the reactor but also reduces the frequency and difficulty of manual cleaning, extending the reactor's service life. It also avoids the problems of reduced reaction rate and product quality caused by residue on the inner wall. Furthermore, by setting a limiting component, the movement of the cleaning scraper in the counter-clockwise direction is restricted, preventing it from continuously scraping the inner wall during normal stirring. This reduces noise and wear caused by friction between the scraper and the inner wall, improving stirring efficiency and equipment stability.

[0017] 2. The counter-clockwise rotation of the stirring rod achieves mixing of materials. This rotation drives the stirring blades to rotate counter-clockwise as well. During rotation, the blades contact the movable plate, causing it to oscillate. This oscillation further enhances the mixing effect on the reactants. Furthermore, by incorporating a limiting component, the counter-clockwise movement of the cleaning scraper is restricted. This prevents the scraper from continuously scraping the inner wall of the vessel during normal mixing, reducing noise and wear caused by friction between the scraper and the inner wall, thus improving mixing efficiency and equipment stability. This optimized mixing method better adapts to materials of different viscosities and quantities, ensuring complete reaction and improving product quality. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0028] Example 1, please refer to Figures 1 to 5 The present invention provides a technical solution: a reaction vessel device, comprising a vessel body 1, an upper cover 2, a cleaning component, and a stirring component, wherein the upper cover 2 is detachably installed on top of the vessel body 1.

[0029] The stirring component includes a stirring rod 5 and stirring blades. The upper end of the stirring rod 5 passes through the upper cover 2 and the two are rotatably connected. The stirring blades are fixedly installed on the lower middle outer side wall of the stirring rod 5. The stirring component also includes a motor 4, which is fixedly installed above the upper cover 2. The output shaft end of the motor 4 is coaxially and fixedly connected to the upper end of the stirring rod 5.

[0030] The function of motor 4 is to provide power to the stirring rod 5, enabling it to rotate in a set direction and speed, thereby achieving the stirring and mixing of materials inside the vessel 1. Motor 4 is either a servo motor or a stepper motor. After motor 4 starts, its output shaft drives the stirring rod 5 to rotate. The stirring rod 5 drives the stirring blades to rotate, and the stirring blades stir and mix the materials inside the vessel 1, ensuring that the materials react fully.

[0031] The cleaning components include a connecting rod 8, two cleaning scrapers 6, and two movable plates 7. A second annular groove 13 is formed on the lower surface of the upper cover 2. The upper end of the cleaning scraper 6 is slidably connected to the upper cover 2 via the second groove 13. One edge of the cleaning scraper 6 abuts against the inner wall of the vessel body 1, and the other edge of the cleaning scraper 6 is hinged to the movable plate 7. A torsion spring is installed at the hinge point between the cleaning scraper 6 and the movable plate 7. Both ends of the connecting rod 8 are fixedly connected to the lower ends of the two cleaning scrapers 6, respectively.

[0032] The cleaning scraper 6 removes materials or reaction products adhering to the inner wall of the vessel 1. Its hinged design with the movable plate 7 allows the movable plate 7 to swing according to the movement of the stirring blades during stirring, enhancing the stirring effect on materials near the inner wall of the vessel 1. The torsion spring provides a restoring force for the swing of the movable plate 7, ensuring it returns to its initial position after the stirring blades have passed. The cleaning scraper 6, as it rotates, scrapes the inner wall of the vessel 1, achieving the purpose of cleaning the inner wall. The connecting rod 8 supports and fixes the lower ends of the two cleaning scrapers 6.

[0033] Specifically, the upper cover 2 is provided with two limiting components. Both limiting components are located on the lower surface of the upper cover 2 and are close to the two cleaning scrapers 6 respectively. The limiting components limit the cleaning scrapers 6 in one direction.

[0034] More specifically, the limiting component includes a locking block 10 and a spring 12. A first sliding groove 11 is provided on the lower surface of the upper cover 2. The spring 12 is located in the first sliding groove 11. The locking block 10 is slidably installed in the first sliding groove 11 of the upper cover 2. One end of the spring 12 is fixedly connected to the upper cover 2, and the other end of the spring 12 is fixedly connected to the locking block 10. The lower side wall of the locking block 10 is inclined. After the cleaning scraper 6 is rotated, it abuts against the locking block 10.

[0035] The locking block 10 and spring 12 allow the locking block 10 to slide within the first slide groove 11. The spring 12 provides elastic support for the sliding of the locking block 10, ensuring smooth contact and separation between the locking block 10 and the cleaning scraper 6. When the cleaning scraper 6 rotates clockwise, its upper end moves past the lower inclined surface of the locking block 10, pushing the locking block 10 upwards within the first slide groove 11. At this time, the locking block 10 cannot limit or obstruct the cleaning scraper 6, allowing it to rotate and move normally. When the cleaning scraper 6 partially rotates counterclockwise, its upper end contacts the lower direct surface of the locking block 10, and the cleaning scraper 6 is limited and obstructed by the locking block 10, preventing it from completing a full rotation.

[0036] When the stirring rod 5 rotates counterclockwise, the stirring blades on the stirring rod 5 abut against the movable plate 7, and the stirring blades push the movable plate 7 to swing. At this time, because the position of the cleaning scraper 6 is limited by the straight surface of the locking block 10, the cleaning scraper 6 will not rotate counterclockwise. Therefore, when the stirring blades contact the movable plate 7, the movable plate 7 will compress the torsion spring and flip at a certain angle. After the stirring blades pass the movable plate 7, the movable plate 7 will be reset by the torsion spring, that is, the movable plate 7 will swing. During the swinging process of the movable plate 7, the material in the vessel 1 is pushed and stirred, thereby further improving the stirring reaction effect of the material.

[0037] When the stirring rod 5 rotates clockwise, the stirring blades on the stirring rod 5 abut against the movable plate 7, and the stirring blades push the movable plate 7 to rotate clockwise. The movable plate 7 then drives the cleaning scraper 6 to rotate clockwise. At this time, during the rotation of the cleaning scraper 6, since it is positioned opposite the inclined surface of the locking block 10, the locking block 10 will compress the spring 12 and retract into the first slide groove 11, thus not hindering the rotation of the cleaning scraper 6, allowing the cleaning scraper 6 to smoothly scrape the inner wall of the vessel body 1.

[0038] Specifically, a feed pipe 3 is fixedly installed on the upper cover 2, and the feed pipe 3 penetrates the upper cover 2. A first control valve is installed on the feed pipe 3. A discharge pipe 9 is fixedly installed on the bottom wall of the vessel body 1. The discharge pipe 9 communicates with the interior of the vessel body 1. A second control valve is installed on the discharge pipe 9.

[0039] The feed pipe 3 is used to add the reaction raw materials into the reactor body 1. The first control valve is used to control the feed flow rate and switch to ensure that the raw materials can enter the reactor body 1 according to the set amount and speed. The discharge pipe 9 is used to discharge the reaction material from the reactor body 1. The second control valve is used to control the discharge flow rate and switch to ensure that the material can be discharged smoothly, while preventing leakage or blockage during the discharge process.

[0040] Specifically, a baffle 14 is fixedly connected to the side edge of the movable plate 7 near the cleaning scraper 6, and the baffle 14 abuts against the cleaning scraper 6. The baffle 14 is used to limit and block the movable plate 7, so that the movable plate 7 can only swing clockwise on the cleaning scraper 6, and cannot swing counterclockwise on the cleaning scraper 6.

[0041] In operation, materials are added to the vessel 1 through the feed pipe 3. The feed pipe 3 is then closed via the first control valve. The motor 4 is then started, causing the stirring rod 5 to rotate counter-clockwise. The stirring rod 5 drives the stirring blades to rotate counter-clockwise, thus mixing the materials in the vessel 1. When the stirring rod 5 rotates counter-clockwise, the stirring blades on it abut against the movable plate 7. Since the cleaning scraper 6 is limited by the straight surface of the locking block 10, it does not rotate counter-clockwise. Therefore, when the stirring rod 5 contacts the movable plate 7, the movable plate 7 compresses the torsion spring and flips at a certain angle. After the stirring rod 5 passes the movable plate 7, the movable plate 7 resets via the torsion spring. During the reset process, the movable plate 7 pushes and stirs the materials in the vessel 1, further improving the mixing effect.

[0042] After the material reaction is complete, open the second control valve, and the material is discharged through the discharge pipe 9. There may be residual material on the inner wall of the vessel 1; at this time, clean the inner wall of the vessel 1. Start the motor 4 to drive the stirring rod 5 to rotate clockwise. During the clockwise rotation of the stirring rod 5, the stirring blades on the stirring rod 5 contact the movable plate 7. At this time, because the baffle 14 fixedly connected to the movable plate 7 is in contact with the cleaning scraper 6, the movable plate 7 cannot be flipped, and the cleaning scraper 6 is not limited by the straight surface of the locking block 10. Therefore, the stirring blades can easily push the cleaning scraper 6 to rotate. During the rotation of the cleaning scraper 6, because it is opposite to the inclined surface of the locking block 10, the locking block 10 will compress the spring 12 and retract into the first sliding groove 11, thus not hindering the rotation of the cleaning scraper 6, allowing the cleaning scraper 6 to smoothly scrape the inner wall of the vessel 1.

[0043] The purpose of this design is to prevent the cleaning scraper 6 from continuously scraping the inner wall of the vessel 1 during normal stirring, thereby preventing excessive noise and wear on the inner wall and extending its service life. Simultaneously, when cleaning of the inner wall of the vessel 1 is required, the cleaning scraper 6 can be effectively scraped by rotating the stirring rod 5 clockwise, ensuring the cleanliness of the inner wall of the vessel 1 and improving reaction efficiency and product quality.

[0044] Example 2, please refer to Figure 6 The main difference between this embodiment and embodiment one is that: the stirring rod 5 is longitudinally slidably connected to the upper cover 2, and an adjustment assembly is provided above the upper cover 2. The adjustment assembly includes a guide rod 15, a slide 16, and an electric push rod 17. The lower end of the guide rod 15 is fixedly connected to the upper cover 2, the electric push rod 17 is fixedly installed on the upper cover 2, the slide 16 is fixedly installed on the output shaft end of the electric push rod 17, the slide 16 is slidably connected to the guide rod 15, the motor 4 is fixedly installed on the slide 16, and the upper end of the stirring rod 5 is rotatably connected to the slide 16.

[0045] When the stirring rod 5 stirs the material inside the vessel 1, the sliding block 16 can be adjusted upwards or downwards by the electric push rod 17, thereby changing the position of the stirring rod 5 inside the vessel 1 and enabling it to stir materials at different depths. This design further improves the stirring effect, especially when processing large quantities of materials or materials with high viscosity, it can better achieve uniform stirring of the materials and ensure the full progress of the reaction.

[0046] In practical use, the position of the stirring rod 5 is adjusted via the electric push rod 17 according to the amount and viscosity of the material, allowing it to better adapt to different stirring needs. Starting the motor 4 drives the stirring rod 5 to rotate, and the stirring blades on the stirring rod 5 mix the material. When cleaning the inner wall of the reactor 1 is required, starting the motor 4 drives the stirring rod 5 to rotate clockwise, and the stirring blades push the movable plate 7 to rotate the cleaning scraper 6 clockwise, thereby scraping the inner wall of the reactor 1. This design not only improves the stirring effect but also enhances the cleaning function, making the reactor more efficient and stable during use.

[0047] This invention solves the problems of reaction products easily adhering to the inner wall of existing reactors and poor stirring effect by rationally designing stirring and cleaning components. It improves the cleanliness and stirring effect of the reactor, thereby enhancing reaction efficiency and product quality, and has high practical value and market application prospects.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
