[0002] In organic synthesis and pharmaceutical intermediate synthesis, stirrers are commonly used equipment, serving to thoroughly mix reactants and promote chemical reactions. Traditional organic synthesis stirrers mostly only have unidirectional stirring capabilities, with limited stirring angles, leading to uneven mixing and affecting reaction efficiency and product quality. Furthermore, the complex internal structure of stirrers makes cleaning difficult, and residual materials can easily interfere with subsequent reactions, affecting product purity. In addition, traditional stirrers are insufficient in terms of ease of operation and automation, making it difficult to meet the diverse and efficient production demands of modern organic synthesis. Therefore, we propose a multi-angle stirrer for pharmaceutical intermediate synthesis. Utility Model Content

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0020] like Figure 1-4 As shown, this utility model is a multi-angle stirrer for the synthesis of pharmaceutical intermediates, including a reaction vessel body 1. A cover 11 is detachably installed on the top of the reaction vessel body 1. A feed pipe 14 and a motor 15 are installed on the top of the reaction vessel body 1. A connecting shaft 16 is connected to the bottom end of the motor 15. A first bevel gear 2 is coaxially installed on the connecting shaft 16. The first bevel gear 2 is installed in a drive box 18. Multiple second bevel gears 21 are equidistantly meshed on the side of the first bevel gear 2. The second bevel gears 21 are installed at the end of a stirring shaft 23. A spiral diverter plate 24 is installed on the stirring shaft 23. Multiple stirring paddles 17 are connected to the bottom end of the connecting shaft 16. A cleaning mechanism is installed on the outside of the reaction vessel body 1. In this structure, the electric motor 15, connecting shaft 16, first bevel gear 2, second bevel gear 21, stirring shaft 23, spiral diverter plate 24, and stirring paddle 17 constitute the stirring system. The electric motor 15 drives the connecting shaft 16 to rotate, which in turn drives the first bevel gear 2 to rotate. The first bevel gear 2 then drives multiple second bevel gears 21 to rotate, realizing multi-angle rotation of the stirring shaft 23 and spiral diverter plate 24. At the same time, the stirring paddle 17 also rotates, achieving the effect of multi-angle mixing and stirring, solving the problems of limited stirring angle and uneven material mixing in traditional stirrers. The cleaning mechanism provides conditions for subsequent cleaning.

[0021] In the above scheme, connecting plates 12 are symmetrically arranged on the edge of the cover 11, and a hydraulic cylinder 13 is provided at the bottom of the connecting plate 12. This structure allows the cover 11 to be raised and lowered under the action of the hydraulic cylinder 13. When it is necessary to clean the internal stirring mechanism, the hydraulic cylinder 13 works to raise the cover 11 and the connected stirring mechanism, making it convenient for operators to clean the inside and solving the problem of difficult cleaning inside the stirrer.

[0022] In the above scheme, a discharge pipe 25 is provided on the side of the reactor body 1, and both the discharge pipe 25 and the feed pipe 14 are equipped with solenoid valves. The solenoid valves enable automated control of the feed and discharge through the control panel 3. Operators can set the feed and discharge time and flow rate on the control panel 3 according to the reaction requirements, which improves the convenience and automation of operation and meets the diversified production needs of modern organic synthesis.

[0023] In the above scheme, the drive box 18 is cylindrical, and the connecting shaft 16 and the stirring shaft 23 are rotatably connected to the drive box 18 through bearings, with the bearings installed inside a waterproof sleeve. The drive box 18 provides a stable installation space for the internal transmission structure. The bearings installed inside the waterproof sleeve effectively prevent liquid from the reactor from entering the drive box 18, ensuring normal transmission between the first bevel gear 2 and the second bevel gear 21, and improving the stability and service life of the equipment.

[0024] In the above scheme, the top of the drive box 18 is connected to the cover 11 via a connecting rod 19. This connection method allows the drive box 18 to move synchronously with the lifting and lowering of the cover 11, ensuring that the transmission structure inside the drive box 18 can still work normally during the lifting and lowering of the cover 11, thus providing structural protection for the lifting and stirring functions of the internal stirring mechanism.

[0025] In the above scheme, the cleaning mechanism includes a water tank 26. A water pump 28 is connected to the top of the water tank 26 via a riser pipe 27. The other end of the water pump 28 is connected via a pipe to multiple nozzles 29 installed on the inner wall of the reactor body 1. When cleaning of the inside of the reactor body 1 is required, the water pump 28 is activated. Water in the water tank 26 is drawn through the riser pipe 27 and then transported through the pipe to the nozzles 29. The water is sprayed from the nozzles 29 to rinse the inside of the reactor. At this time, the internal stirring mechanism drives the water flow to continuously rotate, effectively removing residual materials, ensuring the cleanliness of the reactor interior, and avoiding interference with subsequent reactions.

[0026] In the above scheme, a control panel 3 is provided on the outside of the reactor body 1. The control panel is equipped with corresponding control switches. The operator can control the start and stop and speed of the motor 15, the lifting and lowering of the hydraulic cylinder 13, the opening and closing of the solenoid valve, and the working status of the water pump 28 through the control panel 3, so as to realize the full automation control of the equipment and improve the convenience of operation and production efficiency.

[0027] Working principle:

[0028] This multi-angle stirrer for the synthesis of pharmaceutical intermediates allows the operator to open the solenoid valve on the feed pipe 14 via the control panel 3, allowing the reactants to enter the reactor body 1 through the feed pipe 14. The motor 15 is then started, driving the connecting shaft 16 to rotate. The first bevel gear 2, coaxially mounted on the connecting shaft 16, rotates accordingly. Since the first bevel gear 2 meshes with multiple second bevel gears 21, the rotation of the first bevel gear 2 drives the second bevel gears 21 to rotate, which in turn causes the stirring shaft 23 and the spiral distributor plate 24 to rotate. Simultaneously, the stirring paddle 17 at the bottom of the connecting shaft 16 also rotates under the influence of the connecting shaft 16. The stirring paddle 17, stirring shaft 23, and spiral diverter 24 stir the materials inside the reactor body 1 from different angles, achieving multi-angle mixing and ensuring thorough and uniform mixing to promote the chemical reaction. After the reaction is complete, the solenoid valve on the discharge pipe 25 is opened via the control panel 3, and the reaction products are discharged from the reactor body 1 through the discharge pipe 25. When cleaning the inside of the reactor body 1 is required, the hydraulic cylinder 13 is first activated. The hydraulic cylinder 13 lifts the cover 11 and the connected stirring mechanism via the connecting plate 12 to facilitate subsequent cleaning operations. Then, the water pump 28 is activated, and the water in the water tank 26 is transported by the water pump 28 through the lift pipe 27 and pipeline to the nozzle 29 installed on the inner wall of the reactor body 1. The nozzle 29 sprays water to thoroughly rinse the inside of the reactor and remove residual materials. After cleaning, the water pump 28 is turned off, and the hydraulic cylinder 13 is activated again to lower the cover 11, restoring the equipment to its original state and preparing it for the next use.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
