The materials to be mixed, along with the resulting mixture, enter and exit the tank through a material channel. The mixing assembly performs the mixing process between the materials. The motor utilizes a commercially available design to drive the mixing shafts in both forward and reverse rotation at a specified speed. Three different types of mixing shafts enable efficient, comprehensive mixing of pharmaceutical raw materials, ensuring the quality of the pharmaceutical product. Furthermore, the three mixing shafts use independent drive sources, allowing operators to adjust the speed of the corresponding shaft according to actual needs, further guaranteeing the mixing effect of the pharmaceutical raw materials.

[0007] Preferably, the tank body is made of double-layer stainless steel.

[0008] The wall thickness of a double-walled stainless steel tank can be reduced by 30% to 50%, thus reducing weight and cost, while enhancing resistance to stress corrosion and fatigue performance. This method is common knowledge in the field and will not be elaborated further.

[0012] The fixing block has a rectangular structure, which increases the contact area between the support leg and the external ground. At the same time, the fixing block can be fixedly connected to the external ground by fixing bolts, thereby further ensuring the stability of the support leg's fixed support for the tank.

[0013] Preferably, the material channel includes a feeding assembly and a discharging assembly.

[0014] The feeding assembly is located at the top of the tank for feeding raw materials into the tank, while the discharging assembly is located at the bottom of the tank for discharging materials out of the tank.

[0021] Preferably, the motor is mounted at equal intervals on the top of the tank via a mounting bracket.

[0022] The mounting base provides fixed support for the motor, and the connection between the mounting base and the tank is designed with a chamfer to ensure the contact area with the tank, thereby ensuring the stability of the motor-tank support.

[0023] Preferably, it also includes scrapers, which are installed at equal intervals on the frame-type stirring shaft.

[0024] The scraper design works synergistically with the frame-type stirring shaft to break the stirring dead zone and force the material on the tank wall to flow back to the core stirring area, thereby shortening the stirring time and improving the mixing effect, further demonstrating the practicality of this device.

[0025] The beneficial effects of this utility model are:

[0026] In use, this invention features three sets of stirring shafts of different models. This design allows for efficient mixing of pharmaceutical raw materials across the entire process. Furthermore, the three stirring shafts utilize independent drive sources, enabling operators to adjust the rotation speed of the corresponding stirring shafts according to actual needs. This further ensures the mixing effect of pharmaceutical raw materials, thereby guaranteeing the quality of the pharmaceutical product and facilitating its widespread use.

[0037] Please see Figures 1 to 5This utility model provides a pharmaceutical stirring device, comprising: a tank body 1, a support assembly for fixing and supporting the tank body 1, a material channel for material to enter and exit the tank body 1, and a stirring assembly for mixing the material. The stirring assembly includes a motor 9 and a stirring shaft 10. The motor 9 is located at the top of the tank body 1, and the stirring shaft 10 is located inside the tank body 1, and the stirring shaft 10 is connected to the output shaft of the motor 9 via a coupling. Three sets of motors 9 and stirring shafts 10 are provided, and the three sets of stirring shafts 10 are of different models, corresponding to toothed, frame, and curved blade types from left to right. The tank body 1 is made of double-layer stainless steel. The support assembly includes supports 2 and legs 3. Four supports 2 are evenly spaced on the outer surface of the tank body 1. The legs 3 are bolted to the lower end face of the supports 2. A fixing block 301 is installed on the lower end face, and a fixing bolt is pre-set on the fixing block 301. The material channel includes a feeding component and a discharging component. The feeding component includes a feeding pipe 4, a feeding hopper 5, and a water inlet pipe 6. One or more feeding pipes 4 are equally spaced on the top of the tank body 1. The feeding hopper 5 is located on the top of the tank body 1, on the opposite side of the feeding pipe 4. The water inlet pipe 6 is located on the top of the tank body 1, on one side of the feeding pipe 4. A mesh screen plate 501 is installed inside the feeding hopper 5, and a cover plate 502 is hinged to the top of the feeding hopper 5. The discharging component includes a discharging pipe 7 and a drain pipe 8. The discharging pipe 7 is installed at the bottom of the tank body 1. The drain pipe 8 is located on one side of the discharging pipe 7 and is set at an incline. Control valves are pre-set on both the discharging pipe 7 and the drain pipe 8. The motor 9 is equally spaced on the top of the tank body 1 via the mounting base 901. The scraper blades 11 are equally spaced on the frame-type stirring shaft 10.

[0038] In this embodiment:

[0039] First, the tank 1 is moved to the designated position, and the support leg 3 is installed on the support 2 by bolts to form a support assembly, which plays a role in fixing and supporting the tank 1. At the same time, the fixing block 301 is fixed to the external ground by the fixing bolts preset on the fixing block 301, thereby ensuring the stability of the fixed support for the tank 1.

[0040] Secondly, the corresponding liquid raw material is added into the tank 1 through the feed pipe 4, and the corresponding solid raw material is added into the tank 1 through the feed hopper 5. When the solid raw material is added, the design of the sieve plate 501 can filter and screen the raw material. After the addition is completed, the cover plate 502 is closed.

[0041] Next, the motor 9 on the mounting base 901 drives the designated stirring shaft 10 to rotate, thereby mixing the raw materials. Since three different types of stirring shafts 10 simultaneously mix the raw materials, the raw materials for pharmaceutical manufacturing are mixed efficiently throughout the entire process. As the frame stirring shaft 10 rotates, it drives the scraper 11 to rotate as well, thereby breaking the stirring dead zone and forcibly pushing the material on the wall of the tank 1 back to the stirring core area, thereby shortening the stirring time and improving the mixing effect.

[0042] Then, after the mixing is complete, open the valve on the discharge pipe 7 to discharge the mixed material to the outside through the discharge pipe 7 for the next process;

[0043] Finally, when the inside of tank 1 is not being cleaned, the cleaning fluid is added to the inside of tank 1 through the water inlet pipe 6 to clean the inside of tank 1, and the wastewater after cleaning is discharged to the outside through the drain pipe 8.

[0044] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
