Description

Technical Field

[0001] The utility model belongs to the technical field of pharmaceutical devices, and in particular relates to a stirring device for pharmaceutical use. Background Art

[0002] In the pharmaceutical process, stirring the materials is an important step in the pharmaceutical process, which is used to mix various raw materials together and stir them evenly for the subsequent production of finished products.

[0003] The actual problem encountered is that in the process of stirring existing pharmaceutical raw materials, a stirring rod is usually used to drive the stirring blades to stir the pharmaceutical raw materials. When the blades rotate and stir, strong shear forces are generated inside the liquid. These shear forces can split the surface of the solution or existing air masses and stir them into the medicine to produce a large number of bubbles. The presence of bubbles in the medicine may change the physical properties of the medicine, such as density and viscosity, and thus affect the stability and effectiveness of the medicine. Utility Model Content

[0004] The present application proposes a pharmaceutical stirring device, which can reduce the generation of bubbles in the drug mixture during the preparation and stirring of drug raw materials, thereby improving the stability and effectiveness of the drug.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A pharmaceutical stirring device includes a stirring tank, wherein the upper end surface of the stirring tank is respectively provided with a feeding pipe, a liquid adding pipe and a vacuum valve, a sealing cover is provided at the upper end of the feeding pipe, and a control valve is installed on the liquid adding pipe. The inner bottom surface of the stirring tank is provided with a first rotating groove, a first magnetic strip is provided in the first rotating groove, and the middle part of the first magnetic strip is rotatably connected to the inner bottom surface of the stirring tank through a rotating shaft, the outer bottom of the stirring tank is connected to a support plate, the bottom surface of the support plate is provided with a second rotating groove, a second magnetic strip is provided in the second rotating groove, the middle part of the second magnetic strip is connected to the output shaft of the motor, the motor is connected to the bottom surface of the support plate through a fixing frame, and the bottom surface of the support plate is connected to a support leg.

[0007] In one embodiment of the present application, a screen is provided in the feeding pipe.

[0008] In one embodiment of the present application, a vibrator is installed on the side wall of the feeding pipe.

[0009] In one embodiment of the present application, a funnel is connected to the upper end of the liquid adding tube.

[0010] In one embodiment of the present application, a drain pipe is connected to the side wall of the stirring tank, and a plug is provided at the opening of the drain pipe.

[0011] In one embodiment of the present application, a heating ring is installed on the bottom surface of the stirring tank.

[0012] In one embodiment of the present application, an anti-slip pad is provided on the bottom surface of the supporting leg.

[0013] In summary, the technical solution proposed in this application includes the following beneficial technical effects: this application connects a vacuum valve with a vacuum pump to extract the air in the stirring tank to make the stirring tank vacuum. When the pharmaceutical solution is in a vacuum environment, the internal pressure will be significantly reduced, which causes the gas dissolved in the liquid to begin to precipitate, causing the bubbles to float to the surface of the solution and eventually separate from the mixed liquid. This process can effectively remove bubbles in the pharmaceutical solution during stirring, thereby benefiting to improve the stability and effectiveness of the finished product of the pharmaceutical raw material stirring.

[0029] This embodiment provides a pharmaceutical stirring device, see Figures 1-4As shown, it includes a stirring tank 1, and the upper end surface of the stirring tank 1 is respectively provided with a feeding pipe 2, a liquid adding pipe 3 and a vacuum valve 4, the upper end of the feeding pipe 2 is provided with a sealing cover 21, and the liquid adding pipe 3 is installed with a control valve 31, the inner bottom surface of the stirring tank 1 is provided with a first rotating groove 11, and a first magnetic strip 111 is provided in the first rotating groove 11, and the middle part of the first magnetic strip 111 is rotatably connected to the inner bottom surface of the stirring tank 1 through a rotating shaft 112, and the outer bottom of the stirring tank 1 is connected to a support plate 5, and a second rotating groove 51 is provided on the bottom surface of the support plate 5, and a second magnetic strip 511 is provided in the second rotating groove 51, and the middle part of the second magnetic strip 511 is connected to the output shaft of the motor 6, and the motor 6 is connected to the bottom surface of the support plate 5 through a fixing bracket 61, and the bottom surface of the support plate 5 is connected to a support leg 52.

[0030] In the above embodiment, the upper end surface of the mixing tank 1 is respectively provided with a feeding pipe 2, a liquid feeding pipe 3, and a vacuum valve 4. The feeding pipe 2 is used to add solid pharmaceutical raw materials into the mixing tank 1, and the liquid feeding pipe 3 is used to add liquid pharmaceutical raw materials into the mixing tank 1. Compared with adding the liquid raw materials first and then the solid raw materials through a single feeding port, the solid raw materials will adhere to the feeding port, resulting in waste of pharmaceutical raw materials. Separating the solid and liquid feeding ports prevents the solid and liquid pharmaceutical raw materials from contacting and adhering to the feeding ports, thereby avoiding waste of pharmaceutical raw materials and improving the efficiency of pharmaceutical raw material utilization. The vacuum valve 4 is used to connect to a vacuum pump to remove air from the mixing tank 1 to create a vacuum in the mixing tank 1. According to Henry's law, the solubility of gas in a liquid is proportional to the pressure above it. That is, when the pharmaceutical solution is in a vacuum environment, the internal pressure will significantly decrease, causing the gas dissolved in the liquid to begin to precipitate. These gases gather into bubbles and gradually float to the surface of the liquid and eventually break away from the liquid. This process can effectively remove bubbles from the pharmaceutical solution. Furthermore, a sealing cover 21 is provided at the upper end of the feeding tube 2, and a control valve 31 is installed on the liquid feeding tube 3. After the pharmaceutical raw materials are added, the sealing cover 21 and the control valve 31 are closed to improve the sealing of the mixing tank 1, which is beneficial to maintaining the vacuum degree in the mixing tank 1. In addition, a first rotating groove 11 is provided on the inner bottom surface of the mixing tank 1, and a first magnetic strip 111 provided in the first rotating groove 11 is rotatably connected to the inner bottom surface of the mixing tank 1 through a rotating shaft 112. A second rotating groove 51 is provided on the bottom surface of the support plate 5 at the outer bottom of the mixing tank 1, and the middle part of the second magnetic strip 511 in the second rotating groove 51 is connected to the output shaft of the motor 6. The first magnetic strip 111 and the second magnetic strip 511 are strong magnets that can generate magnetic force and attract each other. When the motor 6 drives the second magnetic strip 511 to rotate in the second rotating groove 51, it will drive the second magnetic strip 511 to rotate with the second magnetic strip. The first magnetic strip 111, which is attracted to the strips 511, rotates within the first rotating groove 11. The rotation of the first magnetic strip 111 can stir the drug solution in the stirring tank 1. The first magnetic strip 111 rotates at the bottom of the stirring tank 1, driving the drug solution to flow and form eddies within the stirring tank 1. This causes the solute molecules in the drug solution to be evenly dispersed as the liquid flows, thereby improving the uniformity of the drug solution. The stirring of the first magnetic strip 111 at the bottom of the drug solution can form turbulence within the solution. The accelerated molecular motion in the turbulence can increase the dissolution rate of the drug raw materials. On the other hand, the transmission through the mutual attraction of the magnetic strips does not require the transmission to be extended into the stirring tank 1 for stirring, which is beneficial to improving the sealing of the stirring tank 1. In addition, the rotation and stirring of the first magnetic strip 111 at the bottom of the drug solution can prevent the gas on the surface of the drug solution from being stirred into the drug solution again to form bubbles, thereby reducing the bubble content in the drug solution and improving the stability of the drug.

[0031] In one embodiment of the present application, see Figure 2 As shown, a screen 22 is provided in the feeding pipe 2 .

[0032] In the above embodiment, the screen 22 is used to screen the solid pharmaceutical raw materials added to the mixing tank 1, removing large impurities or other foreign matter in the raw materials, ensuring uniform particle size and improving mixing efficiency. Furthermore, the screen 22 serves as a safety measure, preventing operators from accidentally inserting their hands or other objects into the mixing tank 1 and causing contamination, thereby ensuring the cleanliness of the mixing tank 1.

[0033] In one embodiment of the present application, see Figure 1 As shown, a vibrator 23 is installed on the side wall of the feeding pipe 2.

[0034] In the above embodiment, the vibrator 23 drives the feeding tube 2 to vibrate and then drives the screen 22 inside the feeding tube 2 to vibrate, thereby increasing the rate at which the solid pharmaceutical raw materials pass through the screen 22, preventing the solid pharmaceutical raw materials from gathering on the screen 22 and causing blockage, and keeping the screen 22 unobstructed.

[0035] In one embodiment of the present application, see Figure 1 As shown, the upper end of the liquid adding tube 3 is connected to a funnel 32 .

[0036] In the above embodiment, the upper end of the liquid adding tube 3 is connected to the funnel 32 to facilitate the addition of liquid pharmaceutical raw materials into the stirring tank 1, thereby preventing the pharmaceutical raw materials from overflowing from the tube mouth of the liquid adding tube 3 during addition, thereby avoiding waste of pharmaceutical raw materials.

[0037] In one embodiment of the present application, see Figure 4 As shown, a drain pipe 12 is connected to the side wall of the mixing tank 1 , and a plug 121 is provided at the opening of the drain pipe 12 .

[0038] In the above embodiment, after the drug solution is stirred in the stirring tank 1 , the plug 121 is removed and the drug solution can be discharged through the drain pipe 12 . When the stirring tank 1 is cleaned, the cleaning liquid can be discharged through the drain pipe 12 .

[0039] In one embodiment of the present application, see Figure 2 As shown, a heating ring 13 is installed on the inner bottom surface of the stirring tank 1.

[0040] In the above embodiment, the heating coil 13 can be used to heat the mixed drug solution to improve the mixing effect of the drug raw materials. For example, for drug raw material liquids or solid-liquid mixtures with high viscosity, appropriate heating can increase the fluidity of the drug raw materials, thereby making them easier to stir evenly. In addition, heating the stirring tank 1 after cleaning can promote the evaporation of water in the stirring tank 1. The high temperature can also sterilize and disinfect the stirring tank 1, improving the cleanliness of the stirring tank 1, and thus helping to improve the purity of the drug stirring and mixing.

[0041] In one embodiment of the present application, see Figure 3As shown, the bottom surface of the support leg 52 is provided with an anti-slip pad 521.

[0042] In the above embodiment, the anti-skid pad 521 can increase the friction between the support leg 52 and the support surface, thereby preventing the mixing device from sliding or tipping over due to vibration or other reasons during operation, thereby improving the overall stability of the mixing device. Optionally, the anti-skid pad 521 is made of rubber or other soft material, which has a certain cushioning effect and can absorb vibration and noise generated by the operation of the mixing tank 1.

[0043] During the actual use of this application: the solid pharmaceutical raw materials that need to be stirred are added to the stirring tank 1 through the feeding tube 2, and the liquid pharmaceutical raw materials are added to the stirring tank 1 through the liquid adding tube 3. After the filling of the pharmaceutical raw materials is completed, the sealing cover 21 at the upper end of the feeding tube 2 and the control valve 31 on the liquid adding tube 3 are closed, and the vacuum valve 4 is connected to the vacuum pump to vacuum the stirring tank 1. The motor 6 is started to drive the second magnetic strip 511 to rotate in the second rotating groove 51, and then the first magnetic strip 111 that is attracted to the second magnetic strip 511 is driven to rotate in the first rotating groove 11 in the stirring tank 1 to achieve stirring of the pharmaceutical solution in the stirring tank 1. In order to avoid the strong magnetic strip from being attracted to the metal and increasing the movement resistance, the tank body of the stirring tank 1 and the support plate 5 can be made of non-metallic materials, such as tempered glass.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
