Description

Technical Field

[0001] This utility model relates to the field of reagent production technology, specifically a reaction vessel for reagent production. Background Technology

[0002] A reaction vessel is a container where physical or chemical reactions occur. Through structural design and parameter configuration, it achieves the heating, evaporation, cooling, and low-to-high-speed mixing functions required by the process. It is widely used in petroleum, chemical, rubber, pesticide, dye, pharmaceutical, and food industries as a pressure vessel to complete processes such as vulcanization, nitration, hydrogenation, hydrocarbonation, polymerization, and condensation. Examples include reactors, reaction vessels, decomposers, and polymerization kettles.

[0003] Upon investigation, a Chinese utility model patent discloses a reaction vessel for reagent production (publication number: CN222174060U), which includes a reaction vessel outer cover, support legs, a heat source inlet, a heat source outlet, a cooling inlet, a cooling outlet, a top cover plate, a hanging plate, a motor mounting base, a pressure rod, and a reaction vessel inner core. The lower part of the reaction vessel outer cover is connected to the support legs, and multiple support legs are evenly distributed at the bottom of the reaction vessel outer cover. The reaction vessel outer cover has a heat source outlet on one side, a cooling outlet on one side, a heat source inlet on one side, a cooling inlet on one side, and an inner plate on one side.

[0004] In the aforementioned patent, the motor is fixed on a motor mounting base, and the stirring rod is connected to the motor shaft. When the motor is working, the stirring rod rotates, causing the stirring blades to stir the materials inside the reactor core. In use, the required reactants are first added to the reactor core and stirred. However, during the stirring process, some reactants may remain inside the reactor. If these residues continue to remain in the reactor and participate in subsequent reactions, they may change the composition and concentration of the reaction system, thereby affecting the reaction equilibrium and rate. This will not only reduce the amount of the target product generated but also reduce the efficiency of the entire reaction.

[0005] Therefore, this utility model provides a reaction vessel for reagent production to solve the above problems. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] This invention provides a reaction vessel for reagent production, aiming to solve the problems mentioned in the background art.

[0026] 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.

[0027] This utility model provides a reaction vessel for reagent production, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the reagent production reactor includes a base plate 1, a reactor shell 2 fixedly installed on the base plate 1, an inner reactor 3 fixedly installed inside the reactor shell 2, and a scraping mechanism provided inside the reactor shell 2 for scraping the inner wall of the inner reactor 3.

[0028] The scraping mechanism includes a rotating shaft 4 rotatably installed inside the reactor shell 2, a connecting rod 5 fixedly installed on the side surface of the rotating shaft 4, a vertical rod 6 fixedly installed on the end of the connecting rod 5 away from the rotating shaft 4, a first hinge seat 7 and a second hinge seat 8 fixedly installed on the side of the vertical rod 6 away from the connecting rod 5, and a first scraper 9 and a second scraper 10 rotatably installed inside the first hinge seat 7 and the second hinge seat 8, respectively.

[0029] Multiple connecting rods 5 are provided, and the connecting rods 5 are arranged in a ring array on the side surface of the rotating shaft 4. The side of the first scraper 9 and the second scraper 10 away from the vertical rod 6 is in contact with the inner wall of the inner reactor 3.

[0030] When using this reagent production reactor, the bottom plate 1 is first placed in a suitable position, and then the reactants are added to the inner reactor 3. As the rotating shaft 4 rotates, the connecting rod 5 also rotates, which in turn drives the vertical rod 6, the first hinge seat 7, the second hinge seat 8, the first scraper 9, and the second scraper 10 to perform circular motion. During the circular motion, the side of the first scraper 9 away from the vertical rod 6 always remains in contact with the inner wall of the inner reactor 3, thereby scraping the inner wall of the inner reactor 3. This scraping action can effectively prevent the reactants from adhering or scaling on the inner wall of the inner reactor 3, ensuring the smooth progress of the reaction and the cleanliness of the reactor. After the first scraper 9 has scraped for a period of time, the rotating shaft 4 rotates in the opposite direction, so that the second scraper 10 remains in contact with the inner wall of the inner reactor 3, and the first scraper 9 no longer contacts the inner wall of the inner reactor 3, reducing the possibility of overheating of the scraper and ensuring the cleanliness of the inner wall of the inner reactor 3, preparing it for the next reaction.

[0031] Furthermore, in order to mix the materials, such as Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, a servo motor 11 is fixedly connected to the top of the reactor shell 2. The output end of the servo motor 11 passes through the top of the reactor shell 2 and is fixedly connected to the top of the rotating shaft 4.

[0032] A fixing block 12 is fixedly connected to the side surface of the rotating shaft 4. Multiple fixing blocks 12 are provided and are arranged in a linear array on the rotating shaft 4. Stirring blades 13 are fixedly connected to both sides of the fixing blocks 12.

[0033] When the reagent production reactor is in use, after the servo motor 11 is started, the rotation of its output end drives the rotating shaft 4 to rotate. The fixed block 12 rotates together with the rotating shaft 4, which in turn drives the stirring blade 13 to perform circumferential motion. During the rotation, the stirring blade 13 can effectively stir the reaction materials, ensuring that the reaction materials are uniformly mixed in the inner reactor 3, improving the reaction efficiency and reaction quality. At the same time, since the fixed block 12 is linearly arrayed on the rotating shaft 4, the stirring blade 13 can cover a wider area during the circumferential motion, further improving the stirring effect.

[0034] It should be noted that, in order to reduce clogging during material feeding, such as Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, a material unloading block 14 is fixedly connected to the bottom end of the rotating shaft 4, and an electric heating wire 15 is fixedly connected to the inner wall of the reactor shell 2. The electric heating wire 15 is located between the reactor shell 2 and the inner reactor 3.

[0035] A feed pipe 16 is fixedly connected to the top of the reactor shell 2, and a discharge pipe 17 is fixedly connected to the bottom of the reactor shell 2. The discharge block 14 is located directly above the discharge pipe 17.

[0036] When the reagent production reactor is in use, the shape of the material dispersing block 14 matches the inlet of the feed pipe 17, which can effectively disperse the material gathered near the inlet of the feed pipe 17 during rotation, avoiding blockage caused by the material being too tightly packed. The setting of the electric heating wire 15 ensures that the temperature inside the reactor is controllable, improving the reaction rate of the reagent and the quality of the product. The feed pipe 16 and the feed pipe 17 are responsible for the input and output of materials, respectively. Their setting makes the reagent production process more automated and convenient. The operator only needs to pour the material into the reactor through the feed pipe 16. After the reaction is completed, the material will be automatically discharged through the feed pipe 17, which greatly improves the production efficiency.

[0037] 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.
