Description

Technical Field

[0001] The invention relates to the technical field of mixing equipment, in particular to a mixing reactor and a mixing component thereof for producing 2-oxoglutaric acid tablets (AKG). Background Art

[0002] 2-Oxoglutarate, also known as α-ketoglutarate, is an important molecule in energy metabolism and amino acid synthesis. It is involved in the oxidation of fatty acids, amino acids and glucose, and plays an important role as a key intermediate in the tricarboxylic acid (TCA) cycle in respiration. Studies have found that AKG, as a potential anti-aging metabolite, can increase lifespan and improve health by controlling multiple functions of organisms. Commonly used experimental animals include Caenorhabditis elegans, experimental mice, rats and common fruit flies. In the above animals, AKG has been confirmed many times to prolong lifespan. In addition, it has also been confirmed that AKG can delay human aging.

[0003] Chinese patent application number 202110482546.5 is a kind of Ca-AKG chewable tablet and its preparation method, which is prepared with calcium α-ketoglutarate as the raw material, and mannitol, citric acid, orange flavor, aspartame, silicon dioxide, sodium stearyl fumarate, and adhesive as auxiliary materials. The present invention also relates to a preparation method of Ca-AKG chewable tablets, including granulation, whole grain, total mixing, tableting, etc. The Ca-AKG chewable tablets of the present invention are stable in nature and suitable for clinical application.

[0004] The preparation method of 2-oxoglutaric acid with Chinese patent application number 202310815226.6 is as follows: 2-methylene glutaric acid is dissolved in a certain amount of dimethyl carbonate, a certain amount of V2O5 / K2O / zeolite composite catalyst is added, and air (or oxygen) is passed through at reflux temperature for oxidation for a certain time. After the reaction is completed, the catalyst is filtered to remove the dimethyl carbonate, and the dimethyl carbonate is removed by vacuum distillation to obtain a crude 2-oxoglutaric acid product with a yield of 98.5%, and the refined 2-oxoglutaric acid is obtained by recrystallization with water with a purity of 99.2%.

[0005] The above patents all require the use of drying and mixing equipment to dry and mix the raw materials. When the raw materials of 2-oxoglutaric acid tablets (AKG) are prepared using the wet granulation principle, the prepared wet granules need to be dried. The natural drying process is long, time-consuming and labor-intensive. When the equipment is used for drying, water droplets are easily condensed on the exhaust pipe of the equipment, and the refluxed water droplets are easy to contaminate the raw materials, thereby affecting the production effect of 2-oxoglutaric acid tablets (AKG). Summary of the invention

When the fan blades rotate with the stirring rod, the magnet blocks on the fan blades act on the magnetic scraper, so that the scraper is reciprocated and deflected, so that the scraper cleans the filter screen, ensuring that the wet air is discharged smoothly. When the temperature of the kettle body gradually increases, the filter holes of the filter screen are enlarged with the assistance of the heated and easily expanded liquid in the driving cylinder, so that the hot and humid air in the kettle body can be quickly discharged, thereby avoiding the deterioration of raw materials caused by excessive temperature in the kettle body.

DETAILED DESCRIPTION

[0022] In order to facilitate understanding of the present invention, the present invention will be described more fully below with reference to the relevant 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] Embodiment 1 like Figures 1 to 6As shown, this embodiment discloses a mixing reactor for producing 2-oxoglutaric acid tablets (AKG), comprising a reactor body 1, an air inlet pipe 2 is arranged on the side wall of the reactor body 1, raw materials for production prepared by wet granulation are added into the reactor body 1, a stirring assembly 3 is arranged in the reactor body 1, a first feeding pipe 7 and a second feeding pipe 8 are arranged on the outside of the reactor body 1, valves 9 are arranged on the first feeding pipe 7 and the second feeding pipe 8, a hopper is arranged on the first feeding pipe 7, raw materials of 2-oxoglutaric acid tablets (AKG) prepared by wet granulation are added into the reactor body 1 with the assistance of the first feeding pipe 7 and the second feeding pipe 8, and valves 9 are arranged on the first feeding pipe 7 and the second feeding pipe 8, the amount of raw materials added into the reactor body 1 can be accurately controlled with the assistance of the valve 9, and the hopper on the first feeding pipe 7 can assist the first feeding pipe 7 in adding raw materials.

[0024] The stirring assembly 3 includes a stirring rod 301, on which a circular shaft 305 is rotatably provided, and a fan blade plate 306 is provided on the outer side of the stirring rod 301. A mounting frame 10 is also provided on the top of the kettle body 1, and a stirring motor 11 is provided on the mounting frame 10. The stirring rod 301 rotates through the mounting frame 10 and is arranged at the output end of the stirring motor 11. After the stirring motor 11 is started, the output end of the stirring motor 11 drives the stirring rod 301 to rotate, and the rotation of the stirring rod 301 drives the fan blade plate 306 to rotate with the assistance of the circular shaft 305. The fan blade plate 306 can stir the raw materials in the kettle body 1 during the rotation process, and when the circular shaft 305 is rotated, the inclination angle of the fan blade plate 306 will change, which will correspondingly change the stirring effect of the fan blade plate 306.

[0025] A discharge pipe 17 is arranged on the outer side of the lower end of the kettle body 1, and a sealing cover is arranged on the discharge pipe 17. The sealing cover and the discharge pipe 17 are connected by bolts and nuts. After the raw materials for producing 2-oxoglutaric acid tablets (AKG) prepared by wet granulation in the kettle body 1 are stirred and dried, the sealing cover on the discharge pipe 17 is opened, and the raw materials in the kettle body 1 will be discharged through the discharge pipe 17, thereby improving the convenience of using the equipment.

[0026] A circular opening 4 is provided at the upper end of the kettle body 1, an exhaust pipe 5 is provided on the outside of the circular opening 4, a filter assembly 6 is provided at the circular opening 4 inside the kettle body 1, and the filter assembly 6 includes a filter net 601. When the raw materials in the kettle body 1 are stirred and dried, the dried moisture is discharged through the exhaust pipe 5 on the circular opening 4, thereby improving the convenience of using the equipment.

[0027] A support frame 12 is provided at the lower end of the kettle body 1, and the kettle body 1 is rotatably connected to the support frame 12. A gear 13 is provided on the outer side of the support frame 12 of the kettle body 1, and a driving screw 14 is rotatably provided on the support frame 12. A turning handle 15 is provided at the side end of the driving screw 14, and a handle 16 is provided on the turning handle 15. The turning handle 15 is rotated by holding the handle 16, and the rotation of the turning handle 15 will drive the rotation of the driving screw 14, and the driving screw 14 will mesh with the gear 13 when rotating, so that the gear 13 rotates, and the rotation of the gear 13 will drive the rotation of the kettle body 1, so that the inclination angle of the kettle body 1 changes, which is beneficial to stirring and drying the raw materials in the kettle body 1 and assisting in discharging.

[0028] During use of the present invention, the raw materials for producing 2-oxoglutaric acid tablets (AKG) are first placed in a wet mixing granulator, low-speed mixing and chopping are started for three minutes, and after uniform mixing, high-speed mixing and chopping are started, and then a binder is added and mixed for 3-5 minutes to form wet granules, and then the prepared wet granules are added into the kettle body 1 through the auxiliary addition of the first feeding pipe 7.

[0029] Start the stirring motor 11, and the output end of the stirring motor 11 drives the stirring rod 301 to rotate. The rotation of the stirring rod 301 drives the rotation of the fan plate 306 through the assistance of the circular shaft 305. During the rotation of the fan plate 306, the fan plate 306 will stir, disperse and lift the wet particles in the kettle body 1, which is beneficial to quickly dry the wet particles in the kettle body 1. After the wet particles in the kettle body 1 are dried, silicon dioxide and sodium stearyl fumarate are added into the kettle body 1 with the assistance of the second feeding pipe 8. As the fan plate 306 rotates, the raw materials in the kettle body 1 are evenly mixed.

[0030] After the raw materials in the kettle body 1 are dried and mixed evenly, the sealing cover on the discharge pipe 17 is opened, and the raw materials in the kettle body 1 are discharged through the discharge pipe 17. The raw materials discharged from the discharge pipe 17 are compressed into tablets by a tablet press to produce 2-oxoglutaric acid tablets (AKG).

[0031] During the process of stirring and drying the wet particles in the kettle body 1, the evaporated moisture can be discharged through the exhaust pipe 5 on the circular mouth 4, and in the process of discharging the raw materials through the discharge pipe 17, the handle 16 is held to rotate the handle 15, and the rotation of the handle 15 will drive the rotation of the driving screw 14, and when the driving screw 14 rotates, it will mesh with the gear 13 to rotate the gear 13, and the rotation of the gear 13 will drive the rotation of the kettle body 1, so that the inclination angle of the kettle body 1 changes, so that the discharge pipe 17 is located at the lower end, which is conducive to the discharge of the raw materials in the kettle body 1.

[0032] Embodiment 2 Based on the mixing reactor for producing 2-oxoglutaric acid tablets (AKG) in the first embodiment, during use, the natural drying process is long, time-consuming and labor-intensive when the wet particles are dried by stirring with the fan blade plate 306. When the evaporated water is discharged through the round mouth 4, the gas flow rate in the exhaust pipe 5 is slow, so that the water is easily condensed in the exhaust pipe 5 and refluxed. Moreover, when the dried raw materials are stirred and mixed, the raw materials are easily splashed onto the filter assembly 6 in the exhaust pipe 5, thereby causing the filter assembly 6 to be blocked, which is not conducive to the discharge of evaporated water. Therefore, the following technical solutions are proposed: like Figures 1 to 7 As shown, a humidity sensor is arranged in the kettle body 1, and the humidity sensor can detect the humidity of the wet particles in the kettle body 1, so that the drying condition in the kettle body 1 can be clearly displayed.

[0033] The center of the stirring rod 301 is provided with a cavity 302, a connecting sleeve 303 is rotatably provided on the stirring rod 301, the air inlet pipe 2 is connected with the connecting sleeve 303, the cavity 302 of the stirring rod 301 is provided with a connecting port 304 at the connecting sleeve 303, a nozzle 307 is provided on the blade plate 306, a through hole 308 connected with the cavity 302 is provided on the circular shaft 305, the through hole 308 is connected with the nozzle 307, and the hot dry gas is passed through the air inlet pipe 2. The hot dry gas is passed into the cavity 302 of the stirring rod 301 with the assistance of the connecting sleeve 303, and then the hot dry gas in the cavity 302 enters the nozzle 307 through the through hole 308 on the circular shaft 305, and then the nozzle 307 sprays the hot dry gas. As the impeller plate 306 rotates and stirs, the nozzle 307 on the impeller plate 306 sprays the hot dry gas to dry the wet particles in the kettle body 1, so that the drying efficiency of the wet particles in the kettle body 1 is higher.

[0034] A first bevel gear 309 is provided on one side of the circular shaft 305 located in the cavity 302, a cover plate 310 is rotatably provided on the side end of the first bevel gear 309, a magnet block 311 is provided on the blade plate 306, a rotating shaft 312 is also rotatably provided in the kettle body 1, the rotating shaft 312 is rotatably inserted into the stirring rod 301, a second bevel gear 313 meshing with the first bevel gear 309 is provided on the rotating shaft 312, a driving motor 314 is provided at the lower end of the kettle body 1, and the output end of the driving motor 314 is connected to the rotating shaft 312. After the driving motor 314 is started, the output end of the driving motor 314 drives the rotation of the rotating shaft 312, and the rotation of the rotating shaft 312 drives the rotation of the second bevel gear 313, and the rotation of the second bevel gear 313 drives the rotation of the first bevel gear 309 through meshing, and the rotation of the first bevel gear 309 drives the inclination angle of the blade plate 306 to change through the circular shaft 305, and the inclination angle of the blade plate 306 changes, which changes its stirring effect.

[0035] A fixing plate 602 is provided on the side of the filter screen 601 close to the stirring rod 301, and the fixing plate 602 is provided on the kettle body 1. A slide plate 603 is provided on the side of the filter screen 601 away from the stirring rod 301. A slide groove 604 is provided on the slide plate 603 at the top of the inner side of the kettle body 1. The slide plate 603 slides in the slide groove 604. A driving cylinder 605 is provided in the slide groove 604. A push rod is provided at the output end of the driving cylinder 605. A liquid that easily expands when heated is provided in the driving cylinder 605. A scraper 606 is provided on the side of the fixing plate 602 close to the slide plate 603 through a torsion spring rotation. The scraper 606 is magnetic. During the rotation of the fan blade plate 306, the distance between the magnet block 311 on the fan blade plate 306 and the scraper 606 will change. When the magnet block 311 on the fan blade plate 306 moves to the bottom of the scraper 606, due to the magnetic force, the scraper 606 will move with the magnet block 311. During the movement of the scraper 606, the blockage of the filter screen 601 will be scraped off. When the scraper 606 deflects to the limit and the blade plate 306 continues to rotate, the distance between the scraper 606 and the magnet block 311 will increase, weakening the magnetic force. Therefore, under the action of the torsion spring, the scraper 606 will return to the initial position, and then with the continuous rotation of the blade plate 306, the scraper 606 will deflect back and forth. When the temperature in the kettle body 1 gradually increases, the heat-expandable liquid in the drive cylinder 605 will increase in volume, causing the top rod of the drive cylinder 605 to extend. When the temperature in the kettle body 1 rises to a threshold, the top rod will contact the slide plate 603. When the temperature continues to rise, the top rod will move against the slide plate 603. The filter holes of the filter screen 601 are diamond-shaped. When the slide plate 603 moves, the filter holes of the filter screen 601 will become larger, which is conducive to the rapid discharge of the hot dry gas in the kettle body 1 to achieve a cooling effect.

[0036] During use of the present invention, the humidity of wet particles in the kettle body 1 is detected with the assistance of a humidity sensor, and the kettle body 1 is made vertical to the ground by the cooperation of the driving screw 14 and the gear 13, after the raw materials are added into the kettle body 1.

[0037] Start the stirring motor 11, and with the assistance of the stirring motor 11, the stirring rod 301 is rotated, and then the fan blade 306 is rotated. During the rotation of the fan blade 306, the air inlet pipe 2 will send the hot dry gas into the cavity 302. Since the fan blade 306 is horizontal to the ground at this time, the cover plate 310 covers the through hole 308 at this time, so the hot dry gas in the cavity 302 will assist in drying the wet particles in the kettle body 1.

[0038] When the humidity sensor detects that the humidity of the wet particles in the kettle body 1 is greater than the threshold value, the device controls the driving motor 314 to operate, so that the output end of the driving motor 314 drives the rotation of the rotating shaft 312, and the rotation of the rotating shaft 312 drives the rotation of the second bevel gear 313, and the rotation of the second bevel gear 313 drives the rotation of the first bevel gear 309 through meshing, and the rotation of the first bevel gear 309 drives the rotation of the fan plate 306 through the circular shaft 305. Through the precise control of the driving motor 314, the angle between the fan plate 306 and the ground is made to be 45°. At this time, since the cover plate 310 is rotatably connected to the first bevel gear 309, and under the action of the gravity of the cover plate 310, the through hole 308 is fully opened. At this time, the hot dry gas in the cavity 302 enters the fan plate 306 through the through hole 308, and then the hot dry gas in the fan plate 306 is ejected through the nozzle 307.

[0039] When the hot drying gas enters the fan blade plate 306, the fan blade plate 306 will serve as a heating source to heat and dry the wet particles in the kettle body 1, thereby increasing the heating area in the kettle body 1, which is beneficial for quickly drying the wet particles in the kettle body 1, and when the nozzle 307 on the fan blade plate 306 sprays the hot drying gas, the hot drying gas directly acts on the wet particles, thereby achieving a better drying effect for the wet particles.

[0040] When the fan blade 306 is tilted to an angle of 45° with the ground, as the stirring rod 301 rotates, the fan blade 306 will lift the wet particles in the kettle body 1, so that the wet particles can be dispersed, and the wet particles can be fully contacted with the hot drying gas, so that the wet particles can be quickly dried, thereby enhancing the drying efficiency and effect of the wet particles in the kettle body 1.

[0041] When the fan blade 306 is tilted to an angle of 45° with the ground, the fan blade 306 will generate upward wind force during the rotation of the stirring rod 301. Under the action of the wind force, the evaporated water will be sent into the exhaust pipe 5, thereby quickly discharging the moisture in the kettle body 1, avoiding the moisture from condensing into water droplets in the kettle body 1 and falling back into the raw materials, thereby ensuring the drying effect of the equipment.

[0042] When the fan blade 306 is tilted to an angle of 45° with the ground, the heating effect of the hot dry gas sent into the kettle body 1 by the air inlet pipe 2 is the best, so the temperature in the kettle body 1 will gradually increase, and as the temperature in the kettle body 1 gradually increases, the heated and easily expanded liquid in the drive cylinder 605 will increase in volume, causing the push rod of the drive cylinder 605 to extend, and when the temperature in the kettle body 1 rises to a threshold value, the push rod will contact the slide plate 603, and when the temperature continues to rise, the push rod will move against the slide plate 603, and the filter holes of the filter screen 601 are diamond-shaped. When the slide plate 603 moves, the filter holes of the filter screen 601 will become larger, which is conducive to the rapid discharge of the hot dry gas in the kettle body 1 to achieve a cooling effect, thereby controlling the temperature in the kettle body 1 to avoid the deterioration of raw materials caused by excessive temperature in the kettle body 1.

[0043] As the detection value of the humidity sensor gradually decreases, the device accurately controls the driving motor 314 to reverse, so that the angle between the fan blade 306 and the ground gradually decreases. When the angle between the fan blade 306 and the ground decreases, the cover plate 310 gradually blocks the through hole 308 with the assistance of gravity, so that the hot dry gas sprayed from the nozzle 307 is reduced. At this time, the lifting effect of the fan blade 306 on the wet particles will also be weakened. Therefore, the hot dry gas sprayed from the nozzle 307 will fully stay in the wet particles to ensure that the wet particles are completely dried.

[0044] During the rotation of the fan blade 306, the distance between the magnet block 311 on the fan blade 306 and the scraper 606 will change. When the magnet block 311 on the fan blade 306 moves to the bottom of the scraper 606, due to the magnetic force, the scraper 606 will move with the magnet block 311, and the blockage of the filter 601 will be scraped off during the movement of the scraper 606. When the scraper 606 deflects to the limit and the fan blade 306 continues to rotate, the distance between the scraper 606 and the magnet block 311 will increase, weakening the magnetic force. Therefore, under the action of the torsion spring, the scraper 606 will return to the initial position, and then as the fan blade 306 continues to rotate, the scraper 606 deflects back and forth to ensure the stability of the filter 601 and avoid the difficulty in discharging moisture due to the blockage of the filter 601.

[0045] The main functions realized by the present invention are: by setting components such as a humidity sensor, a fan blade 306, a magnet block 311, a filter screen 601 and a scraper 606, the humidity of the wet particles in the kettle body 1 is detected with the assistance of the humidity sensor, and then the driving motor 314 is accurately controlled to operate, so that the fan blade 306 is tilted. After the fan blade 306 is tilted, the hot dry gas will enter the fan blade 306 and be ejected from the nozzle 307. The tilted fan blade 306 will lift the wet particles as the stirring rod 301 rotates, so that the hot dry gas is fully in contact with the wet particles, thereby enhancing the drying effect. The tilted fan blade 306 As the stirring rod 301 rotates, an upward wind force is generated to promote the discharge of the humid air in the kettle body 1. When the fan blade 306 rotates with the stirring rod 301, the magnet block 311 on the fan blade 306 acts on the magnetic scraper 606, causing the scraper 606 to deflect back and forth, so that the scraper 606 cleans the filter screen 601 to ensure smooth discharge of the humid air, and when the temperature of the kettle body 1 gradually increases, the filter holes of the filter screen 601 are enlarged with the assistance of the heat-expanding liquid in the driving cylinder 605, so that the humid and hot air in the kettle body 1 can be quickly discharged, thereby avoiding the deterioration of raw materials caused by excessive temperature in the kettle body 1.
