Description

Technical Field

[0001] The invention relates to the technical field of stirring equipment, in particular to a stirring and mixing device and a method for preparing L-carnitine vitamin C adduct. Background Art

[0002] L-carnitine is a key substance in fat metabolism and plays a vital role in the body's fat metabolism. Specifically, L-carnitine promotes the entry of fatty acids into mitochondria for oxidative decomposition, thereby accelerating fat metabolism and reducing fat accumulation. L-carnitine also accelerates the rate of oxidative phosphorylation within mitochondria, improving energy utilization and enhancing the body's energy supply. L-carnitine increases the concentration of free fatty acids in the blood, enhancing the body's ability to utilize fat. L-carnitine can also lower blood lipid and cholesterol levels, preventing cardiovascular disease.

[0003] Chinese patent application number CN202310501725.8 discloses a mixing mixer, comprising a main liquid container, a detachable mixing liquid container, a lifting float rod and a stirring member, wherein the stirring member is located in the main liquid container so as to form a vortex in the liquid in the main liquid container during rotation; wherein the mixing liquid container is provided with a leakage hole for the lifting float rod to pass through, and the lifting float rod is provided with a valve plate portion and a float ball so that when the vortex disappears, the float ball lifts the lifting float rod and causes the valve plate portion to block the leakage hole. However, when the device is used to prepare L-carnitine vitamin C adduct and decolorize and deodorize activated carbon, activated carbon residue is likely to remain in the solution, affecting the preparation effect.

[0004] Chinese patent application number CN202311313688.4 discloses a stirring mixer, including a mixer seat, at least one group of powder storage mechanisms arranged on the mixer seat, and a stirring mixer arranged at a position corresponding to the powder storage mechanism. The stirring mixer includes a stirring and mixing body, a stirring and mixing assembly detachably connected to the stirring and mixing body, a steam exhaust hood connected to the exhaust mechanism is provided at the inlet of the stirring and mixing body, and a diverter plate is provided at the boundary between the mixing and stirring chamber and the pressure chamber. However, when the device is used to prepare L-carnitine vitamin C adduct and decolorize and deodorize activated carbon, activated carbon residue is easily left in the solution, affecting the preparation effect.

[0005] Moreover, the stirring effect of the stirring blade is single, and there are prone to stirring dead corners. When the activated carbon is decolorizing and deodorizing the liquid, the activated carbon tends to sink to the bottom of the mixing tank. As the mixing tank swings, the activated carbon is easily impacted and produces debris, which makes the subsequent filtration effect worse. Moreover, the decolorization and deodorization efficiency of the activated carbon on the liquid is reduced by simply swinging. At the same time, the liquid at the upper layer is difficult to contact with the activated carbon, resulting in poor decolorization and deodorization effect. Summary of the Invention

DETAILED DESCRIPTION

[0022] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0023] Example 1 like Figures 1 to 3 As shown, this embodiment provides a stirring and mixing device for preparing L-carnitine vitamin C adduct, including a mixing tank 1, a rocking component 2 is provided on the outside of the mixing tank 1, and a stirring component 4 is further provided inside the mixing tank 1. In the process of preparing the L-carnitine vitamin C adduct, vitamin C is first dissolved in solvent water to obtain a vitamin C aqueous solution, and L-carnitine inner salt is dissolved in the solvent water, the temperature is raised to 30°C to 60°C, activated carbon is added for decolorization and deodorization, and the solution is filtered to obtain a L-carnitine inner salt aqueous solution, and the temperature is controlled at -10°C to 60°C. The above-mentioned vitamin C aqueous solution is slowly added dropwise to the L-carnitine inner salt solution. After the addition is completed, the temperature is maintained at -10°C to 60°C, and the reaction is kept warm for 2h to 6h. Reduced pressure distillation is performed under a vacuum degree of -0.05MPa to -0.09MPa to remove water as much as possible to obtain a viscous oily product. After freeze-drying, L-carnitine vitamin C adduct powder is obtained. In this process, when the L-carnitine inner salt is dissolved in the solvent water, activated carbon needs to be added for decolorization and deodorization, and filtration is required, which needs to be carried out using a mixing tank 1.

[0024] First, the L-carnitine salt is dissolved in the solvent water in the mixing tank 1, and the rocking component 2 and the stirring component 4 are used to accelerate the dissolution, and then the activated carbon is added into the mixing tank 1 for decolorization and deodorization.

[0025] The stirring assembly 4 includes a main stirring rod 401 and an auxiliary stirring rod 402. The lower end of the main stirring rod 401 is provided with a lower mounting plate 403, and the upper end of the auxiliary stirring rod 402 is provided with an upper mounting plate 404. A stirring blade 405 is provided between the upper mounting plate 404 and the lower mounting plate 403. The stirring blade 405 is elastic. When the main stirring rod 401 and the auxiliary stirring rod 402 rotate synchronously, the stirring blade 405 will also rotate. The rotation of the stirring blade 405 will stir the liquid in the mixing tank 1, thereby accelerating the dissolution of the salt in the L-carnitine.

[0026] A limit bar 407 is provided on the outside of the auxiliary stirring rod 402, and a limit groove matching the limit bar 407 is provided in the main stirring rod 401. A motor 408 is provided at the lower end of the mixing tank 1, and the output end of the motor 408 is connected to the main stirring rod 401. The main stirring rod 401 rotates in coordination with the mixing tank 1, and the auxiliary stirring rod 402 is slidably set on the main stirring rod 401. The motor 408 is started, and the output end of the motor 408 drives the rotation of the main stirring rod 401. The rotation of the main stirring rod 401 drives the rotation of the auxiliary stirring rod 402 through the cooperation of the limit bar 407 and the limit groove, thereby making the main stirring rod 401 and the auxiliary stirring rod 402 rotate synchronously.

[0027] A feed port is provided at the upper end of the mixing tank 1, and a mounting block 6 is also provided on the outside of the mixing tank 1. A mounting shaft 7 is provided on the mounting block 6. A connecting frame 8 is provided on the outside of the mixing tank 1 at the lower end of the mounting block 6. L-carnitine inner salt and activated carbon are added with the assistance of the feed port, making the use of the equipment more convenient.

[0028] The rocking assembly 2 includes a frame 201, an installer 202 is provided on the inner side of the frame 201, and the installation shaft 7 is rotatably matched with the installer 202. A base 203 is also provided on the outer side of the frame 201, and a reciprocating drive 204 is provided on the top of the base 203. The frame 201 and the base 203 are rotatably matched, and the output end of the reciprocating drive 204 is connected to the frame 201, and the installation shaft 7 is rotatably matched with the installer 202. Therefore, the mixing tank 1 can rotate in the frame 201 with the installation shaft 7 as the center, which is conducive to accelerating the dissolution of the L-carnitine salt in the mixing tank 1. The output end of the reciprocating drive 204 can drive the rotation of the frame 201, thereby rotating the mixing tank 1, thereby improving the dissolution rate of the L-carnitine salt in the mixing tank 1.

[0029] A mounting bracket 205 is provided at the top of the frame 201. A driving cylinder 206 is rotatably provided on the side of the mounting bracket 205 close to the mixing tank 1. The output end of the driving cylinder 206 is rotatably coordinated with the connecting bracket 8. After the driving cylinder 206 is started, the output end of the driving cylinder 206 will push the connecting bracket 8 to move, thereby controlling the rotation of the mixing tank 1 with the mounting shaft 7 as the center, making the rotation of the mixing tank 1 more controllable and improving the stability of the equipment.

[0030] A support block 207 is provided on the side of the frame 201 close to the mixing tank 1, and a support frame 208 is provided on the side of the mixing tank 1 close to the support block 207. Limiting holes 209 are provided on the support block 207 and the support frame 208. When the mixing tank 1 needs to be fixed, the support block 207 is aligned with the limiting holes 209 on the support frame 208 with the assistance of the driving cylinder 206, and then the pin is inserted into the limiting hole 209, thereby achieving the fixation of the mixing tank 1, thereby improving the convenience of using the equipment.

[0031] During use of this embodiment, solvent water is added into the mixing tank 1 through the feed port of the mixing tank 1, and then the L-carnitine salt to be dissolved is added into the mixing tank 1 through the feed port. Thereafter, the feed port of the mixing tank 1 is closed, and the mixing tank 1 is heated to 30°C-60°C.

[0032] Start the motor 408, and the output end of the motor 408 will drive the rotation of the main stirring rod 401. The rotation of the main stirring rod 401 drives the rotation of the auxiliary stirring rod 402 through the cooperation of the limit bar 407 and the limit groove, thereby causing the main stirring rod 401 and the auxiliary stirring rod 402 to rotate synchronously, thereby causing the stirring blade 405 to rotate. During the rotation of the stirring blade 405, the liquid in the mixing tank 1 will be stirred, thereby accelerating the dissolution of the salt in the L-carnitine.

[0033] At the same time, the drive cylinder 206 is started reciprocatingly, and the output end of the drive cylinder 206 will reciprocate to push the connecting frame 8, so that the mixing tank 1 swings back and forth with the mounting shaft 7 as the center. During the reciprocating swing of the mixing tank 1, it is beneficial to dissolve the L-carnitine salt faster and improve the stirring effect of the stirring blade 405.

[0034] At the same time, the reciprocating driver 204 will also operate, causing the frame 201 to swing back and forth, thereby causing the mixing tank 1 to swing back and forth as well, which is beneficial for faster dissolution of the L-carnitine salt and improves the stirring effect of the stirring blade 405.

[0035] After the L-carnitine salt is dissolved, the feed port is opened, activated carbon is added through the feed port, and the feed port is closed again. At this time, the motor 408 is no longer started, and the mixing tank 1 is swung with the assistance of the reciprocating drive 204 and the drive cylinder 206. During the swinging process, the activated carbon can better decolorize and deodorize the liquid in the mixing tank 1.

[0036] Finally, the liquid in the mixing tank 1 is poured out and the activated carbon therein is filtered to obtain the L-carnitine saline solution.

[0037] Example 2 In the stirring and mixing device for preparing L-carnitine vitamin C adduct according to the first embodiment, during use, the stirring effect of the stirring blade 405 is single, and a stirring dead angle is easily formed. Moreover, when the activated carbon decolorizes and deodorizes the liquid, the activated carbon tends to sink to the bottom of the mixing tank 1. As the mixing tank 1 swings, the activated carbon is easily impacted and generates debris, which deteriorates the subsequent filtering effect. Moreover, the decolorization and deodorization efficiency of the activated carbon for the liquid is reduced by the swinging alone. At the same time, the liquid at the upper layer is difficult to contact with the activated carbon, resulting in poor decolorization and deodorization effect. Therefore, the following technical solution is proposed: like Figures 1 to 6 As shown, a debris collection component 3 is provided at the side wall of the mixing tank 1, and the debris collection component 3 includes a debris collection pipe 301. A water inlet is provided on one side of the debris collection pipe 301, and a filter hole is provided on the debris collection pipe 301. The debris collection pipe 301 is elastic. When the stirring blade 405 stirs the liquid in the mixing tank 1, the liquid flows, and impurities in the liquid will enter the debris collection pipe 301. With the assistance of the debris collection pipe 301, the impurities in the liquid can be cleaned.

[0038] A filter disc 406 is rotatably provided at the upper end of the auxiliary stirring rod 402, and a pressure sensor is provided on the outside of the filter disc 406. A lifting assembly 5 is provided at the upper end of the mixing tank 1. The filter pore diameter of the filter disc 406 is smaller than the filter pore diameter of the debris collection tube 301. When activated carbon is added, the activated carbon will fall on the filter disc 406. The pressure between the filter disc 406 and the debris collection tube 301 can be detected by the pressure sensor, and the height of the filter disc 406 can be indirectly judged by the pressure value.

[0039] The lifting assembly 5 includes a vertical plate 501, which is arranged at the upper end of the mixing tank 1. A hydraulic cylinder 502 is provided at the side end of the vertical plate 501. The output end of the hydraulic cylinder 502 is provided with an output rod 503. The output rod 503 passes through the mixing tank 1. The lower end of the output rod 503 is provided on the filter disc 406. The output rod 503 can be raised and lowered on the mixing tank 1. When the hydraulic cylinder 502 is started, the output end of the hydraulic cylinder 502 will drive the output rod 503 to rise and fall. The lifting of the output rod 503 will drive the filter disc 406 to rise and fall. When the filter disc 406 rises and falls, it will squeeze the debris collection pipe 301, so that the water inlet of the debris collection pipe 301 changes.

[0040] A discharge pipe 302 is also provided at the side end of the mixing tank 1 at the debris collection pipe 301, and a collecting bottle 303 is provided at the end of the discharge pipe 302. The upper end of the collecting bottle 303 is provided with an external thread, and the inner side of the end of the discharge pipe 302 is provided with an internal thread matching the external thread. The impurities collected by the debris collection pipe 301 will enter the collecting bottle 303 through the discharge pipe 302. The collecting bottle 303 is made of transparent material. After the collecting bottle 303 is full, the collecting bottle 303 is removed to pour out the internal impurities.

[0041] During use of this embodiment, after water and L-carnitine salt are added into the mixing tank 1, the hydraulic cylinder 502 is started to lower the filter disc 406 to the lowest point. The lowering of the filter disc 406 will contact the side wall of the debris collection pipe 301, thereby increasing the value of the pressure sensor. At this time, the value of the pressure sensor is the largest. Since the debris collection pipe 301 is elastic, in this state, the squeezing of the filter disc 406 will close the water inlet of the debris collection pipe 301, thereby reducing the entry of L-carnitine salt into the debris collection pipe 301.

[0042] Then start the motor 408 to slowly rotate the stirring blade 405, thereby slowly flowing the liquid in the mixing tank 1. In the initial state, there is a lot of solid L-carnitine salt. If the liquid flows at a high speed, the solid L-carnitine salt is likely to collide with the stirring blade 405, causing damage to the stirring blade 405.

[0043] After the stirring blade 405 rotates for a set time, the salt in the L-carnitine has dissolved, leaving small particles. At this time, the equipment control causes the hydraulic cylinder 502 to start reciprocating operation, thereby causing the filter disc 406 to move up and down. When the filter disc 406 moves up and down, the filter disc 406 itself will stir the liquid in the mixing tank 1 up and down, promoting the dissolution of the salt in the L-carnitine and increasing the stirring effect in the mixing tank 1.

[0044] During the reciprocating lifting and lowering process of the filter disc 406, the outer side of the filter disc 406 will reciprocate in contact with the debris collection tube 301, thereby causing the debris collection tube 301 to produce a lateral reciprocating motion. When the debris collection tube 301 produces a lateral reciprocating motion, the granular L-carnitine salt affected by the centrifugal force will be moved away from the inner wall of the mixing tank 1, which is conducive to its full contact with water, increasing the stirring effect in the mixing tank 1, reducing the stirring dead angle, and facilitating the dissolution of the L-carnitine salt.

[0045] During the reciprocating lifting of the filter disc 406, the filter disc 406 will lift and lower the auxiliary stirring rod 402, and the reciprocating lifting of the auxiliary stirring rod 402 will cause the stirring blade 405 to deform, thereby changing the stirring effect of the stirring blade 405. When the auxiliary stirring rod 402 rises, the stirring area of the stirring blade 405 will increase, thereby enhancing the stirring effect of the stirring blade 405 on the liquid. When the auxiliary stirring rod 402 descends, the stirring effect of the stirring blade 405 will weaken. Through the change in the stirring effect of the stirring blade 405, the stirring dead angle in the mixing tank 1 is reduced, which is conducive to the dissolution of the L-carnitine salt and the improvement of the dissolution efficiency and effect of the L-carnitine salt.

[0046] After the activated carbon is added in the next stage, the activated carbon will be located on the top of the filter disc 406. The filter disc 406 is lowered to the lowest point by controlling the hydraulic cylinder 502. At this time, the corresponding value of the pressure sensor is the largest. Then, after the set time, the hydraulic cylinder 502 is reversed to make the detection value of the pressure sensor drop to the set threshold. When the detection value of the pressure sensor drops to the set threshold, it indicates that the activated carbon has completed the decolorization and deodorization of the liquid at the bottom. At this time, the equipment will control the operation speed of the motor 408 to increase, thereby strengthening the stirring effect of the stirring blade 405, making the contact between the liquid in the mixing tank 1 and the activated carbon more sufficient, and prompting the activated carbon to decolorize and deodorize the upper layer of the liquid. After the set time again, the equipment controls the filter disc 406 to rise above the liquid surface, so that the detection value of the pressure sensor is reduced to zero. At this time, the operation speed of the motor 408 reaches the fastest, the stirring area of the stirring blade 405 increases, and the stirring speed of the stirring blade 405 is accelerated, so that the liquid flow rate in the mixing tank 1 reaches the maximum.

[0047] During this process, the debris in the activated carbon inevitably enters the liquid in the mixing tank 1, and due to the influence of centrifugal force, the debris in the liquid will be concentrated on the inner wall of the mixing tank 1. When the filter disc 406 rises above the liquid level, the debris collection pipe 301 is no longer squeezed by the filter disc 406, and the water inlet of the debris collection pipe 301 is fully opened. As the liquid flows, the debris located on the inner wall of the mixing tank 1 will enter the debris collection pipe 301 for collection, thereby completing the cleaning of the debris in the mixing tank 1 and reducing the subsequent workload.

[0048] When the filter disc 406 rises above the liquid level, the liquid in the activated carbon will drip through the filter disc 406, reducing the waste of materials caused by the adsorption of the activated carbon and saving costs.

[0049] After the impurities in the mixing tank 1 have been cleaned for a set time, the equipment is stopped and the mixing tank 1 is fixed on the support block 207. Then, the activated carbon bag on the upper end of the filter disc 406 is taken out through the feed port, and the hydraulic cylinder 502 is started by control to lower the filter disc 406 to the lowest point, thereby squeezing the debris collection pipe 301 and closing the water inlet of the debris collection pipe 301. This prevents impurities in the debris collection pipe 301 from accidentally entering the mixing tank 1 when the liquid in the mixing tank 1 is subsequently poured out, thereby ensuring the purity of the saline solution in the L-carnitine, reducing the subsequent filtration process, and improving the processing efficiency of the equipment.

[0050] Example 3 This embodiment provides a method for using a stirring and mixing device for preparing L-carnitine vitamin C adduct, comprising the following steps: Step 1: Add water and L-carnitine salt into the mixing tank 1, and seal the mixing tank 1.

[0051] Step 2: The liquid in the mixing tank 1 is stirred and mixed with the assistance of the rocking component 2 and the stirring component 4 to accelerate the dissolution of the salt in the L-carnitine.

[0052] Step 3: Add activated carbon into the mixing tank 1 to decolorize and deodorize the saline solution in the L-carnitine.

[0053] Step 4: During step 2, the debris collection component 3 can clean the activated carbon debris in the mixing tank 1 to reduce the impact of the activated carbon debris on the saline solution in the L-carnitine; Step 5: Take out the activated carbon and L-carnitine saline solution in the mixing tank 1.

[0054] The main functions achieved by the present invention are as follows: by providing components such as a stirring blade 405, a filter disc 406, a debris collection pipe 301, and a pressure sensor, the position of the filter disc 406 in the mixing tank 1 can be determined with the assistance of the pressure sensor. Then, by controlling the lifting and lowering of the filter disc 406, the lifting and lowering of the filter disc 406 itself can stir the liquid in the mixing tank 1. The lifting and lowering of the filter disc 406 can change the stirring effect of the stirring blade 405, and at the same time, the debris collection pipe 301 can be moved back and forth laterally, which can reduce the stirring dead angle in the mixing tank 1 and facilitate the rapid dissolution of the L-carnitine salt. In addition, during the stage where the activated carbon decolorizes and deodorizes the L-carnitine salt solution, the debris collection pipe 301 and the stirring blade 405 cooperate to collect the activated carbon debris in the liquid, reducing its impact on the quality of the L-carnitine salt solution. With the assistance of the filter disc 406, the L-carnitine salt solution in the activated carbon is dripped, thereby increasing the utilization rate of the material and improving the use effect of the equipment.

[0055] The installation method, connection method or setting method of the present invention are all common mechanical methods, and can be implemented as long as they can achieve their beneficial effects.
