Description

Technical Field

[0001] The utility model relates to the technical field of sartan biphenyl production, in particular to a desolvation crystallization kettle for sartan biphenyl production. Background Art

[0002] A desolventizing crystallizer is a device used in the chemical, pharmaceutical, and food industries. It is primarily used for mixing, reacting, and crystallizing materials. Its operating principle is based on the solubility of a substance and the crystallization process. Under certain temperature and pressure, a substance has a certain solubility in a solvent. When the temperature decreases or the solvent evaporates, the solubility of the solute decreases, causing crystals to precipitate. By controlling temperature, pressure, and other conditions, the desolventizing crystallizer causes the solute in the material to crystallize, thereby achieving separation and purification of the substance.

[0003] In the prior art, the scraping device of the desolventizing crystallization kettle directly scrapes the crystals on the inner wall of the reactor, which will cause opposite forces to be generated between the scraping blades and the rotating shaft when the amount of crystallization is large, thereby causing problems in the connection between the scraping blades and the rotating shaft. At the same time, direct scraping of the wall is likely to result in unclean scraping, thereby causing a decrease in crystallization efficiency. Therefore, the present application provides a desolventizing crystallization kettle for the production of sartan biphenyl to meet the needs. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a desolvation crystallization kettle for the production of sartan biphenyl to solve the problem that the scraping device of the existing desolvation crystallization kettle directly scrapes the crystals on the inner wall of the reactor, which will cause opposite forces to be generated between the scraping blades and the rotating shaft when the amount of crystallization is large, thereby causing problems in the connection between the scraping blades and the rotating shaft.

[0022] like Figures 1 to 3 As shown, the stirring part includes: a stirring rod 3, which is installed in the reactor 1 and is configured so that the top end of the stirring rod 3 is connected to the driving part 2; a plurality of scraping assemblies are evenly installed on the stirring rod 3 and are configured to rotate with the stirring rod 3 to stir the solution in the reactor 1.

[0023] like Figures 1 to 3 As shown, the scraping assembly includes: multiple groups of transmission rods 4, evenly installed on the stirring rods 3; scraping blades 5, installed on the side of the multiple groups of transmission rods 4 away from the stirring rods 3, for scraping the inner wall of the reactor 1.

[0024] like Figures 1 to 3 As shown, the synergistic component includes: a groove 6, which is opened on one side of the scraper blade 5; two groups of elastic members 7, which are respectively installed at the top and bottom of the groove 6; two groups of sliding blocks 8, each group of sliding blocks is connected to a group of elastic members 7, and is configured so that the sliding blocks 8 are slidably connected to the groove 6; a scraper plate 9, which is installed on the side of the two groups of sliding blocks 8 away from the groups of elastic members 7, and is used to directly scrape the crystals on the inner wall of the reactor 1.

[0025] Example 2: Figure 3 As shown, it also includes: two groups of slide grooves 10, which are respectively opened in the top and bottom ends of the groove 6, and the two groups of slide grooves 10 are interconnected with the groove 6; two groups of small sliders 11, each group of small sliders 11 is respectively located in a group of slide grooves 10, and each group of small sliders 11 is respectively connected to a group of sliding blocks 8, so that the sliding blocks 8 slide in the groove 6.

[0026] like Figure 2 As shown, the side of the scraping plate 9 away from the scraping blade 5 is arranged as an arc surface, so that the scraping plate 9 has a better scraping effect.

[0027] like Figure 1 As shown, the temperature control unit includes: a temperature control platform 12 for heating or cooling the reactor 1; and a plurality of support legs 13 installed at the bottom of the temperature control platform 12 for supporting the temperature control platform 12 and the reactor 1 to work.

[0028] In the above scheme, the operations of adding solvent to the reactor 1, collecting crystals, and using the temperature control table 12 are all existing technologies and are controlled by existing control systems. They are well known in the art and are understood by practitioners in this industry, so they will not be repeated here.

[0029] The technical solution provided by the present invention is as follows: first, the solution to be treated is injected into the reactor 1, the temperature control part at the bottom of the reactor 1 starts to work, the temperature control platform 12 is first heated to evaporate the solvent in the solution, and then the temperature is lowered to solidify the crystals; then, the driving part 2 at the top of the reactor 1 is started, driving the stirring rod 3 of the stirring part to rotate, and the multiple groups of scraping components evenly installed on the stirring rod 3 rotate accordingly, and the multiple groups of transmission rods 4 in the scraping components drive the scraping blades 5 to rotate, stirring the solution in the reactor 1, and at the same time the scraping blades 5 scrape the inner wall of the reactor 1 to prevent excessive accumulation of crystals on the wall. When the scraping plate 9 on one side of the scraping blade 5 contacts the reaction vessel 1, the scraping blade 5 is rotated. When crystallization occurs on the inner wall of the reactor 1, the scraper plate 9 pushes the elastic member 7 and the sliding block 8. Since the sliding block 8 is connected to the groove 6 by sliding, and the small slider 11 slides in the slide groove 10 to achieve stable sliding, the elastic member 7 contracts at this time, and the elastic energy is transmitted to the scraper plate 9. The scraper plate 9 is set with an arc surface on the side away from the scraper blade 5, which can better fit the inner wall of the reactor 1 and enhance the scraping effect. At the same time, the setting of the elastic member 7 and the sliding block 8 ensures that the scraper blade 5 is always scraped and buffered by the scraper plate 9 during the scraping process, preventing the scraper blade 5 from blocking the rotation of the stirring rod 3 under the action of crystallization when the stirring rod 3 rotates, thereby damaging the connection between the stirring rod 3 and the scraper blade 5. During the whole process, the temperature control unit continuously adjusts the temperature, the stirring unit continuously stirs the solution and scrapes the inner wall, and the synergistic component enhances the scraping effect and provides buffering, and they work together to complete the desolventizing and crystallization process in the production of sartan biphenyl.

While specific details are described in detail in the preferred embodiments of this invention to provide a thorough understanding, those skilled in the art will be able to fully understand this invention without these details. Furthermore, to avoid unnecessary confusion regarding the essence of this invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
