This device, by setting up a feeding frame and a storage frame, enables the operator to quantitatively deliver raw materials into the reaction tank, increasing the practicality of the entire device.

[0004] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: In chemical production processes, a considerable number of raw materials are inherently corrosive, such as strong acids, strong alkalis, chloride-containing solutions, and strong oxidizing media. These media can easily corrode reaction vessels. Existing devices do not fully combine the corrosive characteristics of the raw materials with targeted anti-corrosion measures, which can easily lead to component damage and media leakage during long-term operation, not only shortening the life of the device but also posing certain installation risks. Utility Model Content

[0005] The technical problem this invention aims to solve is that existing reaction vessels do not have targeted anti-corrosion measures matched to the corrosive characteristics of the raw materials, which makes them prone to media leakage and component damage during operation, thus shortening the service life of the reaction vessels. Therefore, we propose a chemical reaction equipment suitable for corrosive environments.

[0006] To achieve the above objectives, this application adopts the following technical solution: A chemical reaction device suitable for corrosive environments, comprising: a reaction assembly, a stirring assembly mounted on the reaction assembly, an auxiliary assembly disposed inside the reaction assembly, the reaction assembly including a reaction tank body, an inner liner A fixedly connected to the inner wall of the reaction tank body, a tank cover mounted on the upper end of the reaction tank body, an inner liner B fixedly connected to the inner surface of the tank cover, a feeding pipe mounted on the inner liner B, a discharge pipe disposed at the lower end of the inner liner A, the stirring assembly including a motor, the motor fixedly mounted on the upper surface of the tank cover, a stirring shaft fixedly connected to the output end of the motor, one end of the stirring shaft movably penetrating through the tank cover and the inner liner B extending into the inner cavity of the inner liner A, a stirring blade mounted on the stirring shaft, and an auxiliary assembly including a mounting ring, the mounting ring being installed inside the inner liner A, a guide hopper fixedly connected to the mounting ring, and a drain hole provided on the guide hopper.

This is used to form a protective tube through the sleeve and the isolation tube, which protects the stirring shaft and prevents corrosive liquid raw materials from coming into prolonged contact with a certain part of the stirring shaft during feeding, thus preventing damage to the stirring shaft.

[0009] Preferably, the upper end of the feeding pipe extends through the tank cover to its outside, the lower end of the feeding pipe is extended to the bottom of the inner liner B, the output end of the discharge pipe extends through the reaction tank body to its outside, and a valve is installed on the discharge pipe; Used to conveniently drain the processed products from inside liner A.

[0016] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0017] Reference Figures 1 to 5As shown, this utility model provides a technical solution: a chemical reaction device suitable for corrosive environments, comprising: a reaction assembly 1, a stirring assembly 2 installed on the reaction assembly 1, an auxiliary assembly 3 disposed inside the reaction assembly 1, the reaction assembly 1 including a reaction tank body 11, an inner liner A12 fixedly connected to the inner wall of the reaction tank body 11, a tank cover 13 installed at the upper end of the reaction tank body 11, an inner liner B14 fixedly connected to the inner surface of the tank cover 13, a feeding pipe 15 installed on the inner liner B14, and a feeding pipe 15 installed below the inner liner A12. The end is provided with a discharge pipe 16. The stirring assembly 2 includes a motor 21, which is fixedly installed on the upper surface of the tank cover 13. The output end of the motor 21 is fixedly connected to a stirring shaft 22. One end of the stirring shaft 22 movably passes through the tank cover 13 and the inner liner B14 and extends into the inner cavity of the inner liner A12. A stirring blade 23 is installed on the stirring shaft 22. The auxiliary assembly 3 includes a mounting ring 31, which is installed inside the inner liner A12. A guide hopper 32 is fixedly connected to the mounting ring 31, and a drain hole 33 is opened on the guide hopper 32.

[0018] The reaction vessel body 11 and the vessel cover 13 of this device have undergone anti-corrosion treatment, such as electroplating, passivation, and coating with an anti-corrosion layer. All other connecting pipes of the device are installed on the inner linings A12 and B14, and these connecting pipes have also undergone anti-corrosion treatment, further increasing the overall corrosion resistance of the device. When a chemical reaction is required, the liquid raw materials are sequentially added to the inner lining A12 through the feed pipe 15. These liquid raw materials then flow directly to the guide hopper 32 and are discharged into the inner lining A12 through the drain hole 33 on the guide hopper 32. The guide hopper 32 and the drain hole 33 disperse the liquid raw materials, preventing prolonged contact between the added liquid raw materials and a certain point on the inner lining A12, which would accelerate the corrosion rate at that point. During this process, the operator can start the motor 21 according to actual production requirements. The motor 21 drives the stirring shaft 22 to rotate, and the stirring shaft 22 drives the stirring blades 23 to rotate, stirring and mixing the liquid raw materials. After the reaction is complete, the products are discharged from the discharge pipe 16.

[0019] Reference Figure 1 , Figure 3 Figure 4 and Figure 5 As shown, this utility model provides a technical solution: a chemical reaction equipment suitable for corrosive environments, wherein an installation ring 121 is fixedly connected to the inner wall of the lining A12, and the installation ring 31 is assembled with the installation ring 121 by bolts and nuts, with the nuts installed on the bottom surface of the installation ring 121; a sleeve 141 is fixedly connected to the bottom surface of the lining B14; an isolation tube 34 is installed in the middle of the guide bucket 32, with the upper end of the isolation tube 34 corresponding to the sleeve 141; and the stirring shaft 22 corresponds to the upper end of the isolation tube 34 and the sleeve 141.

[0020] The mounting ring 31 and mounting ring 121 can be easily assembled together using bolts and nuts, which facilitates subsequent operations. When the reaction vessel body 11 and the vessel cover 13 are installed together, the upper end of the isolation tube 34 is inserted into the sleeve 141, so that the isolation tube 34 and the sleeve 141 form a whole. The stirring shaft 22 is located inside it to prevent the raw materials from scouring a certain part of the stirring shaft 22 for a long time during the feeding process, which would affect its service life.

[0021] Reference Figures 1 to 5 As shown, this utility model provides a technical solution: a chemical reaction device suitable for corrosive environments. The upper end of the feeding pipe 15 extends through the tank cover 13 to its outside, and the lower end of the feeding pipe 15 is extended to the bottom of the inner lining B14. The output end of the discharge pipe 16 extends through the reaction tank body 11 to its outside. A valve 17 is installed on the discharge pipe 16. Four sets of stirring blades 23 are provided, with stirring holes 24 on each set. A cover 35 is provided on the mounting ring 31, and the cover 35 corresponds to the guide hopper 32. The guide hopper 32 is configured as a funnel. A liquid guide pipe 36 is installed on the cover 35, and the feeding pipe 15 corresponds to the liquid guide pipe 36.

[0022] When the reaction vessel body 11 and the vessel cover 13 are installed together, the lower end of the feed pipe 15 is inserted into the liquid guide pipe 36, and the guide hopper 32 is sealed with the cover 35, so that the liquid raw material added from the feed pipe 15 can only be discharged from the drain hole 33, preventing the added liquid raw material from splashing after contacting the guide hopper 32 due to the height difference. At the same time, because the stirring blade 23 has stirring holes 24, some raw material can pass through the stirring holes 24 during the stirring process, which can break up the vortex and form a composite flow field of main flow and perforated secondary flow, increasing the mixing efficiency of the entire device. After the reaction is completed, the valve 17 is opened to discharge the product from the discharge pipe 16.

[0023] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
