Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, and in particular to a high-efficiency hydrochloric acid reaction vessel for liquid ferric chloride. Background Technology

[0002] In a broad sense, a reaction vessel is a stainless steel container that undergoes physical or chemical reactions. The structural design and parameter configuration of the container are carried out according to different process requirements. The design conditions, process, inspection, manufacturing and acceptance must be based on relevant technical standards to achieve the heating, evaporation, cooling and low-speed mixing reaction functions required by the process. The hydrochloric acid in liquid ferric chloride requires the use of a reaction vessel.

[0003] Existing reaction vessels typically rely on a single rotating shaft to drive an agitator shaft, a relatively simple method that is inconvenient for mixing multiple agitators in the hydrochloric acid reaction of liquid ferric chloride. This results in uneven mixing, as a single impeller cannot effectively manage both axial and radial flow, easily creating dead zones (especially at the bottom and surface). This leads to localized FeCl3 crystallization or residue deposition, and the bottom sediment cannot be effectively disturbed, requiring frequent shutdowns for manual cleaning, increasing corrosion risk and maintenance costs. Consequently, the practicality of the reaction vessel is reduced. Therefore, this invention proposes a high-efficiency hydrochloric acid reaction vessel for liquid ferric chloride to solve the above problems. Utility Model Content

[0004] To address the aforementioned problems, this invention proposes a high-efficiency hydrochloric acid reaction vessel for liquid ferric chloride, which solves the problem of uneven mixing caused by the inconvenience of using multiple stirring shafts in the existing stirring method for the hydrochloric acid reaction of liquid ferric chloride.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a high-efficiency hydrochloric acid reaction vessel for liquid ferric chloride, comprising a reaction vessel body, a cover plate installed at the top of the reaction vessel body, a feed inlet installed on one side of the top of the cover plate, a feeding port installed on the other side of the top of the cover plate, an electric heating wire installed inside the reaction vessel body, a slag discharge port installed at the middle position of the bottom of the reaction vessel body, a discharge port installed at the bottom of one side of the reaction vessel body, a stirring mechanism installed inside the reaction vessel body, and a spraying mechanism installed below the cover plate;

[0006] The stirring mechanism includes a servo motor, a mounting bracket, a drive gear, a rotating shaft, a turbine propeller, an anchor propeller, and a wall scraping assembly. The mounting bracket is installed above the cover plate. The servo motor is installed at the top of the mounting bracket, and the drive gear is installed at the bottom of the mounting bracket. The output end of the servo motor is connected to one end of the mounting bracket. The rotating shaft is installed inside the reactor body. The top of the rotating shaft is connected to the bottom of the drive gear. A turbine propeller is installed above the outer wall of the rotating shaft, and an anchor propeller is installed below the outer wall of the rotating shaft.

[0007] A further improvement is that the wall scraping assembly includes a connecting rod, a side scraper, and a bottom scraper. The connecting rod is installed above the outer wall of the rotating shaft, a side scraper is installed at one end of the connecting rod, and a bottom scraper is installed at the bottom end of the side scraper.

[0008] A further improvement is made in that: the spraying mechanism includes a driven gear, a connecting shaft, a nozzle, and a water supply pipe. The driven gear is installed above the cover plate, and one side of the driven gear meshes with one side of the driving gear. A connecting shaft is installed at the bottom end of the driven gear, and the bottom end of the connecting shaft extends into the interior of the reactor body. A nozzle is installed at the bottom end of the connecting shaft, and a water supply pipe is connected to the bottom of the nozzle via a rotary joint. One end of the water supply pipe extends above the cover plate.

[0009] A further improvement is that a jacket is provided on the outside of the main body of the reactor, which improves the reaction efficiency of the main body of the reactor.

[0010] A further improvement is made in that: a damper is provided at the bottom of the reactor body, a telescopic spring is provided on the outer side wall of the damper, and rubber vibration isolation pads are installed at both the top and bottom of the telescopic spring, with the top rubber vibration isolation pad connected to the bottom of the reactor body.

[0011] A further improvement is that multiple dampers are provided below the main body of the reactor, and the multiple dampers are distributed at equal intervals at the bottom end of the main body of the reactor.

[0012] The beneficial effects of this utility model are as follows: By setting a stirring mechanism inside the reactor body, and utilizing the cooperation between the servo motor, mounting frame, drive gear, rotating shaft, turbine propeller, anchor propeller, connecting rod, side scraper, and bottom scraper of the stirring mechanism, the material can be stirred by combining the turbine propeller and the anchor propeller. The turbine propeller generates a strong radial flow, improving the liquid phase mass transfer efficiency and shortening the reaction time. The anchor propeller rotates close to the bottom of the reactor, thoroughly eliminating residue deposits such as Fe(OH)3 and preventing agglomeration that clogs the slag discharge port, resulting in better material mixing and thus greatly improving the practicality of the reactor in use. By setting a spraying mechanism below the cover plate, and utilizing the cooperation between the driven gear, connecting shaft, nozzle, and water pipe of the spraying mechanism, the nozzle can be driven to rotate. Regular cleaning with deionized water or dilute alkaline solution reduces material residue and makes cleaning the reactor body more convenient and faster, thus greatly improving the convenience of using the reactor.

[0017] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0018] according to Figure 1 , 2As shown in Figure 3, this embodiment proposes a high-efficiency hydrochloric acid reactor for liquid ferric chloride, including a reactor body 1, a cover plate 2 installed at the top of the reactor body 1, a feed inlet 3 installed on one side of the top of the cover plate 2, a feeding port 4 installed on the other side of the top of the cover plate 2, an electric heating wire installed inside the reactor body 1, a slag discharge port 5 installed at the middle position of the bottom end of the reactor body 1, a discharge port 6 installed at the bottom of one side of the reactor body 1, a stirring mechanism installed inside the reactor body 1, and a spraying mechanism installed below the cover plate 2.

[0019] The stirring mechanism includes a servo motor 7, a mounting bracket 8, a drive gear 9, a rotating shaft 10, a turbine propeller 11, an anchor propeller 12, and a wall scraping assembly. The mounting bracket 8 is installed above the cover plate 2. The servo motor 7 is mounted on the top of the mounting bracket 8, and the drive gear 9 is mounted on the bottom of the mounting bracket 8. The output end of the servo motor 7 is connected to one end of the mounting bracket 8. The rotating shaft 10 is installed inside the reactor body 1. The top of the rotating shaft 10 is connected to the bottom of the drive gear 9. The turbine propeller 11 is mounted on the upper part of the outer wall of the rotating shaft 10. An anchor paddle 12 is installed below the outside of the rotating shaft 10. In use, the servo motor 7 is started to drive the drive gear 9 to rotate, which in turn drives the rotating shaft 10 to rotate, thereby driving the turbine paddle 11 and the anchor paddle 12 to stir the hydrochloric acid solution. The turbine paddle 11 generates a strong radial flow, which improves the liquid phase mass transfer efficiency and shortens the reaction time. The anchor paddle 12 rotates close to the bottom of the vessel, which completely eliminates the deposition of residues such as Fe(OH)3 and avoids agglomeration and blockage of the slag discharge port 5, resulting in better mixing of materials and thus greatly improving the practicality of the reactor in use.

[0020] The wall scraping assembly includes a connecting rod 13, a side scraper 14, and a bottom scraper 15. The connecting rod 13 is installed above the outer wall of the rotating shaft 10. The side scraper 14 is installed at one end of the connecting rod 13, and the bottom scraper 15 is installed at the bottom end of the side scraper 14. In use, the connecting rod 13 can drive the side scraper 14 and the bottom scraper 15 to rotate, and the side scraper 14 and the bottom scraper 15 are used to scrape the material from the inner wall of the reactor body 1.

[0021] The spraying mechanism includes a driven gear 16, a connecting shaft 17, a nozzle 18, and a water supply pipe 19. The driven gear 16 is mounted above the cover plate 2, and one side of the driven gear 16 meshes with one side of the driving gear 9. The connecting shaft 17 is mounted at the bottom end of the driven gear 16, and the bottom end of the connecting shaft 17 extends into the interior of the reactor body 1. The nozzle 18 is mounted at the bottom end of the connecting shaft 17, and the water supply pipe 19 is connected to the bottom of the nozzle 18 via a rotary joint. One end of the water supply pipe 19 extends to the cover plate 2. Above plate 2, when in use, the external pump is started to draw the cleaning solution into the nozzle 18 through the water pipe 19 and spray it out. At this time, the servo motor 7 is started. Since the driving gear 9 and the driven gear 16 mesh with each other, the driven gear 16 drives the nozzle 18 to rotate with the help of the rotary joint, so as to carry out a more comprehensive cleaning treatment of the inside of the reactor body 1. This makes it more convenient and faster to clean the reactor body 1, thereby greatly improving the convenience of using the reactor.

[0022] The outer side of the reactor body 1 is provided with a jacket 23, which improves the reaction efficiency of the reactor body 1. During use, the heating or cooling medium is circulated to achieve precise heating or cooling of the material inside the reactor, ensuring that the reaction is carried out within the optimal temperature range, while avoiding local overheating or crystallization precipitation.

[0023] A damper 20 is provided at the bottom of the reactor body 1. A telescopic spring 21 is provided on the outer wall of the damper 20. Rubber vibration isolation pads 22 are installed at both the top and bottom of the telescopic spring 21. The top rubber vibration isolation pad 22 is connected to the bottom of the reactor body 1. Multiple dampers 20 are provided below the reactor body 1. The multiple dampers 20 are distributed at equal intervals at the bottom of the reactor body 1. In use, the damper 20 and the telescopic spring 21 absorb vibration energy through elastic deformation, reducing the transmission of low-frequency vibration. The rubber vibration isolation pads 22 use viscoelasticity to suppress high-frequency vibration. The two layers work together to improve the stability of the equipment and the comfort of the working environment.

[0024] Working principle: First, the operator adds hydrochloric acid into the reactor body 1 through inlet 3. Then, the servo motor 7 drives the drive gear 9 to rotate, which in turn drives the rotating shaft 10, which in turn drives the turbine propeller 11 and the anchor propeller 12 to stir the hydrochloric acid solution. Next, liquid ferric chloride is slowly injected through inlet 4. At this time, the heating wire is activated to heat the solution and stir it, allowing the solutions to react. The turbine propeller 11 generates a strong radial flow, improving the liquid phase mass transfer efficiency and shortening the reaction time. The anchor propeller 12 rotates close to the bottom of the reactor, thoroughly eliminating residue deposits such as Fe(OH)3 and preventing agglomeration. By blocking the slag discharge port 5 and utilizing the interaction between the damper 20, the extension spring 21, and the rubber vibration isolation pad 22, noise generation can be reduced. After the reaction is completed, the solution is discharged through the discharge port 6, and the precipitate is discharged through the slag discharge port 5. Then, the external pump is started to draw the cleaning solution into the nozzle 18 through the water pipe 19 and spray it out through the nozzle 18. At this time, the servo motor 7 is started. Since the driving gear 9 and the driven gear 16 mesh with each other, the driven gear 16 drives the nozzle 18 to rotate under the cooperation of the rotary joint, so as to perform a more comprehensive cleaning treatment on the inside of the reactor body 1.
