Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, specifically to an aminobutyric acid purification kettle. Background Technology

[0002] Gamma-aminobutyric acid (GABA) is an important chemical raw material with wide applications in pharmaceuticals, food, and other fields. In the production process of GABA, purification is a key step to ensure its quality, and the purification vessel is the core equipment for achieving GABA purification.

[0003] The GABA raw material and purification reagent are added to the purification vessel to purify the GABA raw material. During the purification process, a large number of bubbles are easily generated during material stirring and reaction. These bubbles adhere to the surface of GABA crystals, which will hinder the full contact between the purification reagent and the crystals, affect the sufficiency of the purification reaction, and lead to a decrease in the purity of GABA, which seriously affects the product quality. The existing GABA purification vessel has only a simple stirring and filtration structure, which cannot effectively deal with the bubbles, thus making it difficult for personnel to use. Utility Model Content

[0012] (III) Beneficial Effects This invention utilizes a combination of a drive bevel gear, an upper bevel gear, a small shaft, an arc-shaped impeller, and a crushing component. The drive bevel gear engages with the upper bevel gear and the crushing component on both sides. When the drive bevel gear rotates clockwise, the upper bevel gear rotates counterclockwise due to the engagement, while the crushing component rotates clockwise. The upper bevel gear drives the small shaft and the outer arc-shaped impeller to rotate. When the arc-shaped impeller rotates, it generates an upward thrust and lateral turbulence on the material in the upper part of the vessel. At the same time, the crushing component rotates in the opposite direction, directly cutting the bubbles in the vessel and breaking them into smaller bubbles. The convection generated by the reverse rotation is opposite to the flow direction of the arc-shaped impeller, which can enhance the internal turbulence of the material, disrupt the surface tension balance of the bubbles, and further inhibit foam formation, thereby improving the purity of GABA and benefiting personnel.

[0015] 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.

[0016] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments; Example: The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Please refer to the accompanying drawings. Figures 1 to 5 Please refer to the following for details regarding the aminobutyric acid purification vessel provided in this application. Figure 1 , Figure 3 and Figure 4 The vessel includes a vessel body 1; a stirring mechanism 2 is rotatably installed inside the vessel body 1; a fixing frame 3 is fixedly installed on both sides of the inner wall of the vessel body 1 near the stirring mechanism 2; a drive bevel gear 301 is rotatably installed on the inner wall of the fixing frame 3; an upper bevel gear 302 is driven and installed above one side of the drive bevel gear 301; a small shaft 303 is installed at the center of the upper bevel gear 302; an arc-shaped impeller 304 is installed on the outer side of the bottom end of the small shaft 303; a crushing component 305 is installed below the upper bevel gear 302 and on the outer side of the small shaft 303; and a heating mechanism 4 is installed on the inner wall of the vessel body 1. Please refer to this carefully. Figure 3 and Figure 4 The crushing assembly 305 includes a lower bevel tooth 3051 located below the upper bevel tooth 302 and outside the small shaft 303. A large shaft 3052 is mounted below the lower bevel tooth 3051 and outside the small shaft 303. A serrated impeller 3053 is mounted outside the large shaft 3052.

[0017] Specifically, the stirring mechanism 2 allows for thorough stirring and reaction of GABA and purification reagents. The driving bevel gear 301 is powered by an independent external motor. As an intermediate transmission component, the driving bevel gear 301 meshes with the upper bevel gear 302 and lower bevel gear 3051 on its two sides. Since the upper bevel gear 302 and lower bevel gear 3051 are located above and below the driving bevel gear 301 respectively, when the driving bevel gear 301 rotates clockwise, the upper bevel gear 302 rotates counterclockwise due to the meshing relationship, while the lower bevel gear 3051 rotates clockwise. The upper bevel gear 302 drives the small shaft 303 and the outer arc-shaped impeller 304 to rotate. When the arc-shaped impeller 304 rotates, it generates an upward thrust and lateral turbulence on the material in the upper part of the vessel 1. On the one hand, this disperses large bubbles accumulated on the liquid surface, preventing the accumulation of bubbles and the formation of a stable foam layer; on the other hand, the turbulence causes the material to circulate. The circulating flow reduces the conditions for continuous bubble formation due to stagnation. At the same time, the lower bevel gear 3051 drives the main shaft 3052 and the outer serrated impeller 3053 to rotate in opposite directions. The sharp toothed structure on the edge of the serrated impeller 3053 generates strong shear force and turbulence when rotating, directly cutting the bubbles in the vessel 1 and breaking them into smaller bubbles. The convection generated by the reverse rotation is opposite to the flow direction of the arc impeller 304, which can enhance the disturbance inside the material, disrupt the surface tension balance of the bubbles, and further inhibit foam formation. The reverse rotation of the arc impeller 304 and the serrated impeller 3053 makes the material in the upper and lower parts of the vessel 1 form a complex vortex and shear, rather than a single-direction flow. The reverse thrust of the upper and lower parts makes the material produce a kneading effect in the vertical direction. The bubbles are repeatedly stretched and broken in the up and down movement, and the temperature required for purification is provided by the heating mechanism 4.

[0018] Please refer to this carefully. Figure 1 and Figure 2 The top of the vessel body 1 is provided with a feed inlet 101, and the side of the bottom of the vessel body 1 is provided with a discharge outlet 102.

[0019] Please refer to this carefully. Figure 1 and Figure 2 Control valves 103 are installed on the outside of both the feed inlet 101 and the discharge outlet 102.

[0020] Specifically, in order to deliver GABA raw material and purification reagents into the reactor body 1, when it is necessary to add GABA raw material or related solvents into the reactor body 1, the control valve 103 of the feed inlet 101 is opened to allow the material to smoothly enter the reactor body 1 from the feed inlet 101. If it is necessary to stop feeding, the control valve 103 is closed to block the material passage and avoid excessive raw material entering the reactor body, which would cause the reaction inside the reactor body to become unbalanced. After the GABA is purified in the reactor body 1, the control valve 103 of the discharge outlet 102 is opened to allow the purified product to be discharged from the discharge outlet 102 on the side of the bottom of the reactor body 1 and enter the subsequent processing stage.

[0021] Please refer to this carefully. Figure 3and Figure 5 A metal filter screen 5 is installed inside the vessel body 1 near the discharge port 102. A polyester fiber layer 501 is installed on one side of the metal filter screen 5, and an activated carbon adsorption layer 502 is provided on one side of the polyester fiber layer 501.

[0022] Please refer to this carefully. Figure 1 and Figure 5 The heating mechanism 4 includes a heating wire 401 disposed on the inner wall of the vessel body 1, and a thermometer 402 is installed on the side of the vessel body 1.

[0023] Please refer to this carefully. Figure 1 and Figure 3 The stirring mechanism 2 includes a motor 201 located at the top of the vessel body 1, and the output end of the motor 201 is located inside the vessel body 1 where a stirring assembly 202 is installed.

[0024] Specifically, to achieve efficient purification of GABA, motor 201 serves as the power source, converting electrical energy into mechanical energy. This mechanical energy, via its output shaft, drives the stirring assembly 202 inside the vessel 1 to rotate. Driven by motor 201, the stirring assembly 202 generates shearing, convection, and diffusion effects on the material inside the vessel 1, ensuring uniform mixing. The metal filter 5 primarily intercepts large particles of impurities in the material, preventing them from clogging subsequent fine filtration layers or being discharged with the product, thus affecting the purification effect. The material initially filtered by the metal filter 5 enters the polyester fiber layer 501. The polyester fiber, with its porous and chemically resistant properties, further traps fine particles of impurities. The activated carbon adsorption layer 502 enhances the clarity of the material, providing a purer matrix for subsequent activated carbon adsorption. Its porous structure captures small molecule pollutants such as organic impurities, pigments, and odors in the material through physical adsorption, completing multi-stage removal of impurities before the material is discharged from the reactor 1. The heating wire 401 generates heat through electrical current, directly heating the material inside the reactor 1. Heat is transferred to the material via thermal conduction, bringing it to the required purification temperature. The temperature sensor 402, a resistance temperature detector, monitors the temperature of the material inside the reactor 1 in real time and feeds the temperature signal back to the external control system.

[0025] Working principle: By opening the feed inlet 101 and control valve 103, the aminobutyric acid raw material and related solvents are introduced into the reactor body 1 through the feed inlet 101. The heating mechanism 4 is activated: the inner wall heating wire 401 is energized and heats up, raising the temperature inside the reactor through heat conduction. The temperature sensor 402 monitors and feeds back the temperature signal in real time to ensure that the temperature is stable within the range required for purification. Then, the stirring mechanism 2 is activated. The motor 201 at the top of the reactor body 1 drives the stirring assembly 202 to rotate, mixing the materials inside the reactor and ensuring uniform contact between the raw material and the solvent. Then, the external power motor drives the drive bevel gear 301 on the fixed frame 3 to rotate, and through meshing transmission, the upper bevel gear 302 and the lower bevel gear 302 rotate. The tooth 3051 rotates in the opposite direction, and the arc-shaped impeller 304 rotates with the upper bevel tooth 302, generating an upward thrust and a transverse vortex on the material in the upper part of the vessel 1, breaking up large bubbles on the liquid surface and reducing the accumulation of bubbles due to solvent evaporation caused by heating. The serrated impeller 3053 rotates in the opposite direction with the lower bevel tooth 3051, generating shear force through the sharp tooth structure to break the bubbles. During the reaction, the stirring component 202 promotes full contact between the material and the heating environment. After purification, the control valve 103 of the discharge port 102 is opened, and the purified aminobutyric acid product is discharged from the discharge port 102 through the metal filter screen 5, the polyester fiber layer 501, and the activated carbon adsorption layer 502 in a step-by-step filtration process.

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.
