Description

Technical Field

[0001] The utility model relates to the technical field of hydrochloric acid purification, in particular to a purification device for producing high-purity reagent hydrochloric acid. Background Art

[0002] Hydrochloric acid, commonly known as hydrochloric acid, is an aqueous solution of hydrogen chloride gas. It is a colorless, transparent, monoprotic strong acid. Hydrochloric acid is extremely volatile, which is why a white mist may appear above a container of concentrated hydrochloric acid. This mist is actually small droplets of hydrochloric acid formed when the hydrogen chloride evaporates and combines with water vapor in the air. The relative molecular mass of hydrochloric acid is 34.46. Hydrochloric acid is an aqueous solution of hydrogen chloride at varying concentrations. It has a pungent odor and is highly corrosive. Its relative density is 1.19, its melting point is -112°C, and its boiling point is -83.7°C.

[0003] Evaporation and distillation are often used in the purification of hydrochloric acid. Distillation is a thermodynamic separation process that utilizes the different boiling points of components in a mixed liquid or liquid-solid system to evaporate the low-boiling-point component and then condense it to separate the entire component. It is a unit operation process that combines the two unit operations of evaporation and condensation.

[0004] In the existing technical solution, during the purification of hydrochloric acid, water droplets are formed on the top of the purification kettle during the distillation and recondensation process. During the accumulation process, the water droplets fall back into the interior of the purification kettle due to their large size, which requires further distillation and condensation, affecting the work efficiency of hydrochloric acid production. Summary of the Invention

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] The utility model provides a technical solution:

[0027] See also Figures 1 to 4 A purification device for producing high-purity reagent hydrochloric acid includes a purification kettle 1, an exhaust port 9 is connected to the eccentric position of the top of the purification kettle 1, a protrusion 8 is fixedly connected to the side wall of the purification kettle 1, a servo motor 2 is connected to the bottom of the purification kettle 1, and a rotating rod 3 is connected to the output end of the servo motor 2. The rotating rod 3 is rotatably connected to the inside of the purification kettle 1, and a cleaning component 4 is sleeved on the outer surface of the top of the rotating rod 3;

[0028] The cleaning assembly 4 includes a connecting frame 41 fixedly sleeved on the outer surface of the top of the rotating rod 3, a cleaning roller 42 is rotatably connected to the top of the connecting frame 41, a scraper 43 is fixedly connected to the bottom of the cleaning roller 42 inside the connecting frame 41, and a cleaning pipe 44 is connected to the right side of the bottom of the connecting frame 41. A cleaning sponge is provided on the outer surface of the cleaning roller 42, and the scraper 43 is triangular in shape. The top of the scraper 43 produces a squeezing effect on the outer surface of the cleaning sponge;

[0029] The outer surface of the rotating rod 3 is rotatably connected to the collecting frame 5 at the bottom of the connecting frame 41. The bottom of the outer surface of the collecting frame 5 is connected to a drain pipe 6. The drain pipe 6 passes through the purification kettle 1 and extends to the outer surface of the purification kettle 1. A collecting tank is provided inside the collecting frame 5. The drain pipe 6 passes through the collecting tank provided inside the collecting frame 5. A fixing rod 10 is fixedly connected to the side of the outer surface of the collecting frame 5 away from the drain pipe 6. The end of the fixing rod 10 away from the collecting frame 5 is connected to the left side of the inner wall of the purification kettle 1.

[0030] By adopting the above technical solution, when in use, the hydrochloric acid raw material to be purified is placed inside the purification kettle 1. After the raw material is heated, due to the different boiling points, the water and other substances mixed in the raw material will become steam and be discharged from the exhaust port 9, thereby obtaining a pure hydrochloric acid solution. However, during the discharge process, some of the steam will be cooled and condensed after contacting the top wall of the purification kettle 1, thereby generating condensed water. As time goes by, the condensed water gathers to form water droplets, which are likely to drip back into the interior of the purification kettle 1, thereby affecting the working efficiency of hydrochloric acid production. During the purification process, the servo motor 2 is used to drive the rotating rod 3 to rotate, and the rotation of the rotating rod 3 drives the connecting frame 41 to rotate, thereby driving the cleaning roller 42 to rotate to clean the water droplets on the top of the purification kettle 1, thereby ensuring the efficiency of hydrochloric acid production. The purification efficiency of the purification kettle 1 is improved. At the same time, when the cleaning roller 42 has been cleaned for a long time, it will cause the cleaning roller 42 to absorb more water droplets and be unable to absorb them again, thereby affecting the normal adsorption of water droplets. When the cleaning roller 42 rotates following the connecting frame 41, it will rub against the purification kettle 1 to produce the characteristic of self-rotation, so that the cleaning roller 42 will be squeezed into contact with the scraper 43. At this time, the setting of the scraper 43 has a scraping effect on the cleaning roller 42, and the water droplets absorbed on the outer surface of the cleaning roller 42 are scraped to the inside of the connecting frame 41. Then, the cleaning pipe 44 is used to transport the liquid inside the connecting frame 41 to the inside of the collecting frame 5. At the same time, the drain pipe 6 is used to discharge the liquid to the outer surface of the purification kettle 1, which ensures the adsorption effect of the cleaning roller 42 on the condensed water, which is beneficial to improving the production efficiency of the purification kettle 1.

[0031] Specifically, such as Figure 2-Figure 4As shown, the outer surface of the rotating rod 3 is fixedly sleeved with multiple groups of stirring components 7, and the stirring component 7 includes a stirring drum 71 fixedly connected to the outer surface of the rotating rod 3. A sliding groove is opened inside the stirring drum 71, and a spring 72 is fixedly connected to the inner side of the sliding groove. The end of the spring 72 away from the inner side wall of the sliding groove is fixedly connected to the stirring rod 73, and the end of the stirring rod 73 away from the stirring drum 71 is fixedly connected to the push plate 74. The stirring rod 73 is slidably connected in the sliding groove by the spring 72, and the rebound force of the spring 72 is greater than the gravity of the stirring rod 73.

[0032] There are multiple bumps 8 , which are equal in size and distributed in a ring array. The position of the stirring rod 73 is adapted to the position of the bumps 8 .

[0033] By adopting the above technical solution, when the raw materials placed inside the purification kettle 1 need to be stirred and heated, the servo motor 2 drives the rotating rod 3 to rotate, and the rotation of the rotating rod 3 drives the stirring drum 71 to rotate. The rotation of the stirring drum 71 drives the stirring rod 73 and the push plate 74 to rotate, so as to achieve the effect of stirring the raw materials placed inside the purification kettle 1. During the rotation of the push plate 74, it will contact the protrusion 8, and thus be squeezed and contracted by the protrusion 8 to the inside of the stirring drum 71, thereby causing the push plate 74 to move from the edge of the purification kettle 1 to the center, and the raw materials near the side wall of the purification kettle 1 inside the purification kettle 1 are driven to the center of the purification kettle 1 by the movement of the push plate 74, thereby achieving the effect of mixing and stirring the raw materials. After the push plate 74 passes over the protrusion 8, it is no longer squeezed by the protrusion 8. At this time, under the action of the spring 72, the push plate 74 is pushed back to the edge of the purification kettle 1, and so on and so forth, forming a continuous alternating mixing of the raw materials at the edge and center of the purification kettle 1.

[0034] Working principle: When in use, the hydrochloric acid raw material to be purified is placed inside the purification kettle 1, and then the servo motor 2 drives the rotating rod 3 to rotate, and the rotation of the rotating rod 3 drives the stirring drum 71 and the stirring rod 73 to rotate, and the rotation of the stirring rod 73 drives the push plate 74 to rotate, so as to achieve the effect of stirring and heating the raw materials inside the purification kettle 1. At the same time, the stirring rod 73 is squeezed by the convex block 8 during the rotation process, and the stirring rod 73 is squeezed and the spring 72 is squeezed, and then slides inside the stirring drum 71, thereby driving the push plate 74 to slide, and the raw materials on the side of the purification kettle 1 are pushed to the center of the purification kettle 1, so as to achieve the effect of fully stirring the raw materials.

[0035] The cleaning roller 42 is driven by the suction cup 42 and the suction cup 43 is pulled out of the cleaning chamber 1 so that the cleaning roller 42 is pulled out of the cleaning chamber 1 and the suction cup 43 is pulled out of the cleaning chamber 1.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
