Description

Technical Field

[0001] This utility model relates to the field of chemical technology, and in particular to a reaction vessel for hydrochloric acid concentration. Background Technology

[0002] Hydrochloric acid, as an important chemical substance, has been widely used in various fields such as metallurgy, chemical industry, and medicine. Specifically, in the metallurgical field, dilute hydrochloric acid solutions are widely used to remove oxides from metal surfaces. This process is crucial for improving the purity and quality of metals. With the continuous development and expansion of industrial production, a large amount of low-concentration waste hydrochloric acid containing various impurities is generated during the production process. If this waste hydrochloric acid is not treated, it will not only waste resources but also cause serious environmental pollution. In order to achieve resource recycling and reduce environmental pollution, it is urgent to effectively concentrate this low-concentration hydrochloric acid. In addition, high-concentration hydrochloric acid is an indispensable raw material in some chemical production processes, which has further promoted the research and development of hydrochloric acid concentration technology and related equipment. Through continuous technological innovation and equipment upgrades, hydrochloric acid concentration processes have made significant progress in improving efficiency, reducing costs, and reducing environmental impact, providing strong support for the sustainable development of industrial production.

[0003] Traditional reactors are mostly rigid structures with fixed volume and height, which cannot flexibly adjust the reaction space according to the hydrochloric acid processing volume, resulting in low adaptability to different working conditions. Existing reactors use detachable bodies, and the inner lining of different volumes can be replaced according to the processing volume to improve the applicability of the equipment. However, during the stirring process, the raw materials may not be thoroughly stirred, resulting in the accumulation of raw materials at the bottom, which affects the concentration efficiency and effect. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a reaction vessel for hydrochloric acid concentration, which aims to improve the problems of insufficient stirring and solution accumulation in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a hydrochloric acid concentration reactor, comprising an outer shell cover, a stirring mechanism fixedly connected to the top of the outer shell cover, a reactor body provided at the bottom of the outer shell cover, and an assembly mechanism fixedly connected to the outer wall of the reactor body. The assembly mechanism is used for installation and disassembly, facilitating user maintenance. The stirring mechanism includes a motor, the bottom of which is fixedly connected to the top right side of the outer shell cover. A transmission assembly is fixedly connected to the output end of the motor. A concave frame is rotatably connected to the right outer wall of the transmission assembly. A fixing column is fixedly connected to the bottom of the transmission assembly. A rotating assembly is fixedly connected to the bottom of the fixing column. A scraping assembly is slidably connected to the outer wall of the fixing column.

[0006] As a further description of the above technical solution:

[0007] The combined mechanism includes a fixing block, the left side of which is fixedly connected to the outer wall of the vessel body. A rotating component is rotatably connected inside the fixing block, and a knob is threadedly connected to the outer wall of the rotating component. A heating component is fixedly connected to the outer wall of the vessel body, and a support frame is fixedly connected to the middle of the outer wall of the vessel body. An outlet is provided at the bottom of the vessel body.

[0008] As a further description of the above technical solution:

[0009] The transmission assembly includes a first bevel gear, the middle of which is fixedly connected to the output end of the motor. The top of the outer wall of the first bevel gear is meshed with a second bevel gear, and the bottom of the outer wall of the first bevel gear is meshed with a third bevel gear.

[0010] As a further description of the above technical solution:

[0011] The rotating assembly includes a rotating disk, the middle of which is fixedly connected to the bottom of a fixed column, and a stirring column is fixedly connected to the top edge of the rotating disk.

[0012] As a further description of the above technical solution:

[0013] The scraping assembly includes a hollow column, the top of which is rotatably connected to the outer wall of a fixed column, and scrapers are fixedly connected to the left and right edges of the hollow column.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the concave frame drives the bevel gear transmission structure to achieve the opposite rotation of the upper and lower stirring columns, which greatly enhances the mixing degree of the solution.

[0039] Working principle: By activating the concave frame 203, the bevel gear 2021 at the output end rotates, and the top meshing gear 2022 rotates accordingly, causing the bottom fixed column 204 to rotate along with the top rotating disk 2051. The hollow column 2061 on the outer wall of the fixed column 204 is rotated by the top bevel gear 2023. The upper and lower stirring columns 2052 rotate in different directions, resulting in higher mixing. The outer wall also has a scraper 2062 that scrapes the inner wall of the vessel body 4 to prevent the solution from getting stuck on the inner wall, reduce the accumulation of raw materials at the bottom, and increase the concentration efficiency.

[0040] Align the outer cover 1 with the bottom vessel body 4, hold the handle 5 and rotate it around the fixing post 3021 to the top. The fixing block 301 on the outer wall of the outer cover 1 will lock in place. Then turn the knob 303 to tighten and fix it. There are multiple such structures on the top of the outer wall of the vessel body 4, which facilitates disassembly and observation of the internal situation.
