Abstract
Description
Technical Field
[0001] This application relates to the technical field of chemical drug production, and specifically to an efficient mixing device for chemical drug production. Background Art
[0002] Chemical drugs are raw drug substances and their preparations prepared by synthetic or semi-synthetic methods, new effective monomers and their preparations extracted from natural substances or by fermentation, and optical isomers and their preparations of known drugs prepared by methods such as resolution or synthesis. During the production process of chemical drugs, it is necessary to efficiently mix different components and reactants.
[0003] The Chinese patent authorization announcement number: CN220026770U discloses a drug production mixing device. This solution has a simple structure, is convenient to control the heating temperature, can effectively improve the stirring effect, and can effectively prevent drugs from adhering to the inner wall of the tank, and can better meet the usage requirements.
[0004] However, during the drug mixing process, due to their relatively large weight, large particles tend to sink to the bottom of the mixing tank under the action of gravity. When the stirrer starts to agitate the solution or mixture, although the solution starts to agitate, due to the inertia of these heavy particles and the centrifugal force generated during the stirring process, the heavier particles cannot be effectively stirred and dispersed into the solution, resulting in uneven mixing, so that the drug components cannot be evenly distributed throughout the mixture, thereby reducing the mixing effect.
[0005] Therefore, it is necessary to provide an efficient mixing device for chemical drug production to solve the above problems.
[0006] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the concept of this application, and therefore, it may include information that does not constitute the prior art. Summary of the Utility Model

[0025] Such as Figures 1-4As shown in the figure, the present application provides an efficient mixing device for chemical production, including: a base 1 and a mixing component 8. A stirring tank 2 is installed on the top of the base 1. The stirring tank 2 can be fixed to the base 1 by welding. A feed pipe 3 and a discharge pipe 4 are respectively installed on the outer side wall of the stirring tank 2. A rotating shaft 7 is rotatably connected inside the stirring tank 2.

The upper disc 81 and the lower disc 83 can be fixed to the outer side wall of the rotating shaft 7 by bolts. Confluence grooves 84 are respectively opened inside the upper disc 81 and the lower disc 83. And a plurality of nozzles 85 are installed on one side of the upper disc 81 and the lower disc 83 close to each other. The nozzles 85 are communicated with the confluence grooves 84. A liquid inlet groove 9 is opened inside the rotating shaft 7. Both confluence grooves 84 are communicated with the liquid inlet groove 9. A communication hole communicated with the liquid inlet groove 9 is opened on the outer side wall of the rotating shaft 7, so that the liquid inlet groove 9 is communicated with the confluence grooves 84. A plurality of cutting blades 82 are installed between the upper disc 81 and the lower disc 83; wherein, a liquid pumping component 5 for pumping the liquid medicine at the bottom of the stirring tank 2 into the liquid inlet groove 9 is further installed on the outer side wall of the stirring tank 2, and a motor 10 for driving the rotating shaft 7 to rotate is further installed at the bottom of the stirring tank 2.
[0026] This solution is used for efficiently mixing different components and reactants to ensure uniform mixing and reaction rate during chemical production. Specifically, the chemical solution to be mixed is injected into the inside of the stirring tank 2 through the feed pipe 3. By setting the motor 10, the rotating shaft 7 and the stirring blades 6 on the outer side wall can be controlled to rotate, so as to fully stir the mixed solution in the stirring tank 2. In addition, through the set liquid pumping component 5, the solution at the bottom of the stirring tank 2 can be pumped into the liquid inlet groove 9 located above. The mixed solution in the liquid inlet groove 9 is respectively discharged into the confluence grooves 84 in the upper disc 81 and the cutting blades 82. Finally, the mixed solution is discharged through the nozzles 85 on one side of the upper disc 81 and the lower disc 83 under high pressure to form a liquid column, and mutual impact of the liquid is generated when the nozzles 85 collide, promoting the mixing reaction. And with the rotation of the rotating shaft 7, the impacted liquid diffuses around under the action of centrifugal force, and after passing through the cutting blades 82 again, multiple mixing is realized. The mixed solution at the bottom can be continuously pumped to the upper position, ensuring continuous flow of the mixed solution, reducing the problem of accumulation at the bottom of the stirring tank 2, improving the mixing effect. Finally, the mixed chemical solution is discharged through the discharge pipe 4 for subsequent treatment.
[0027] It should be noted that the mixing component 8 is located inside the stirring tank 2 and close to the upper position.
[0028] Such as Figure 2As shown, the motor 10 is installed at the bottom of the mixing tank 2. The motor 10 is fixed to the bottom of the mixing tank 2 by bolts, and the output end of the motor 10 penetrates through the mixing tank 2 and is connected to the rotating shaft 7.
[0029] In this embodiment, the provided motor 10 is used to drive the rotating shaft 7, as well as the stirring blades 6 and the mixing assembly 8 on the outside to rotate. On the one hand, the stirring blades 6 are used to fully stir the chemical solution in the mixing tank 2. On the other hand, centrifugal force is provided for the mixed solution in the mixing assembly 8.
[0030] As Figures 1-2 shown, the liquid pumping assembly 5 includes a water pump 51 installed on the outer wall of the mixing tank 2. The water pump 51 is fixed to the outer wall by bolts. An output pipe 52 is installed at the output end of the water pump 51, and an input pipe 53 is installed at the input end of the water pump 51. The input pipe 53 is connected to the mixing tank 2 and the end of the input pipe 53 is located near the lower position inside the mixing tank 2 to ensure that the mixed solution at the bottom of the mixing tank 2 can be discharged into the mixing assembly 8. One end of the output pipe 52 is rotatably connected to the rotating shaft 7. The end of the output pipe 52 can be connected to the rotating shaft 7 by a rotary joint, and the output pipe 52 is connected to the liquid inlet groove 9.

[0032] As Figures 3-4 shown, a plurality of cutting knives 82 are evenly distributed in a ring, making the mixing of the chemical solution more uniform.
[0033] As Figure 4 shown, the positions of the multiple nozzles 85 on the upper disc 81 and the multiple nozzles 85 on the lower disc 83 correspond one by one.
[0034] In this embodiment, the mixed solution is discharged through the nozzles 85 on one side of the upper disc 81 and the lower disc 83 under high pressure, and can form liquid columns and collide with each other to promote the progress of the mixing reaction.
[0035] As Figure 4 shown, the cross-sections of the multiple nozzles 85 are conical, which increases the discharge speed of the mixed solution at the nozzles 85 and improves the mixing effect.
[0036] Working principle:
[0037] The chemical solution to be mixed is injected into the interior of the stirring tank 2 through the feed pipe 3. The motor 10 is provided to control the rotation of the rotating shaft 7 and the stirring blades 6 on the outer wall, so as to fully stir the mixed solution in the stirring tank 2. In addition, the liquid extraction assembly 5 is provided to convey the solution at the bottom of the stirring tank 2 to the liquid inlet tank 9 located above. The mixed solution in the liquid inlet tank 9 is respectively discharged into the confluence grooves 84 in the upper disc 81 and the cutting knife 82. Finally, the mixed solution is discharged through the nozzles 85 on one side of the upper disc 81 and the lower disc 83 under high pressure to form a liquid column, and the mutual impact of the liquid is generated when the nozzles 85 collide, promoting the progress of the mixing reaction. And with the rotation of the rotating shaft 7, the impacted liquid diffuses around under the action of centrifugal force, and after passing through the cutting knife 82 again, multiple mixing is realized, and the mixed solution at the bottom can be continuously conveyed to the upper position, reducing the problem of accumulation at the bottom of the stirring tank 2 and improving the mixing effect. Finally, the mixed chemical solution is discharged through the discharge pipe 4 for subsequent treatment.
