Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and in particular to a pharmaceutical mixing tank. Background Technology

[0002] In the pharmaceutical manufacturing industry, with the continuous improvement of pharmaceutical quality requirements, the role of pharmaceutical mixing tanks is becoming increasingly important. Some pharmaceutical mixing tanks have relatively simple agitator designs, resulting in differences in the degree of mixing between the edge and center areas of the tank during the mixing process. This is especially true for some pharmaceutical raw materials with high viscosity or significant density differences, making it difficult to achieve a comprehensive and uniform mixing effect. This leads to unstable quality of the final produced pharmaceuticals and performance deviations between different batches. During the pharmaceutical production process, pharmaceutical residues can easily remain on the inner wall of the mixing tank and on the agitator components. If not cleaned in time, these residues will deteriorate, affecting the quality of the next batch of pharmaceuticals. Therefore, we have introduced a new pharmaceutical mixing tank. Utility Model Content

Two connecting shaft blocks are fixedly connected to the middle of the outer surface of the rotating rod. Several stirring blades are fixedly connected to the outer surfaces of the two connecting shaft blocks. The drive motor is fixedly connected to the right side of the lower end of the fixed plate.

[0007] By adopting the above technical solution: the connecting shaft block is connected to the rotating rod, and the rotating rod drives it to rotate at high speed, which stirs the medicine and makes the medicine evenly mixed in the medicine tank.

[0008] Preferably, the auxiliary component includes two fixed shafts.

The lower ends of the three upper scrapers and the upper ends of the three lower scrapers are jointly fixedly connected to three side scrapers. The two fixed shafts are respectively fixedly connected to the upper part and the lower part of the outer surface of the rotating rod.

[0009] By adopting the above technical solutions, the upper and lower scrapers and the side scrapers can scrape off the residual agents on the inner wall of the tank, the bottom of the screen and the bottom of the tank, reducing waste and residual effects. The stirring rod expands the stirring range, enhances the mixing effect of the agents, and improves the stirring quality in all aspects.

[0010] Preferably, the filtering assembly includes a screening frame, three locking blocks are fixedly connected to the outer surface of the screening frame, a screening mesh is fixedly connected to the lower frame wall of the screening frame, and the screening frame is snapped into the upper part of the inner wall of the medicine container.

[0011] By adopting the above technical solution, the screening frame is attached to the upper part of the inner wall of the pharmaceutical tank, and together with the screening mesh, it can perform initial filtration of the pharmaceutical raw materials when they enter the pharmaceutical tank, preventing large particles of impurities from entering the stirring area and ensuring the purity of the stirred pharmaceuticals.

[0012] Preferably, the positional dimensions of the three card blocks are matched one-to-one with the positional dimensions of the three card slots, and the screening mesh has a honeycomb structure.

[0016] Preferably, all of the stirring blades are fan-shaped and inclined at an angle of 20 degrees.

[0017] By adopting the above technical solution: the fan-shaped stirring blades with a 20-degree inclination increase the contact area with the agent when rotating, improve the stirring efficiency, and enable the agent to be mixed quickly and thoroughly.

[0018] Preferably, the upper stirring rods and the lower stirring rods are arranged in a ring around the rotating rod, with the upper stirring rod facing each other, and the other ends of the upper stirring rods and the lower stirring rods do not contact the stirring blades.

[0021] By adopting the above technical solution: the upper scraper is close to the bottom of the screening screen, and the lower scraper is close to the bottom of the reagent tank, which effectively cleans the residual reagents in various places, ensures the cleanliness of the reagent tank, and prevents the residual reagents from affecting the quality of the next stirring.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. In this utility model, the pharmaceutical mixing tank effectively improves the problem of mixing uniformity through a uniquely designed drive device and auxiliary components. The drive motor drives the main gear disc, which in turn causes the meshing disc and rotating rod to rotate. The rotating rod has fan-shaped stirring blades that are inclined at a 20-degree angle, which increases the contact area with the pharmaceutical agent and efficiently mixes the agent. At the same time, the upper and lower scrapers and stirring rods of the auxiliary components work together. The stirring rods are distributed in a ring around the rotating rod and work in different areas with the stirring blades to mix the agent in all directions, ensuring that the agent in each area of ​​the tank is fully mixed. This greatly improves the mixing uniformity and effectively solves the problem of unstable agent quality and batch performance differences caused by uneven mixing, thus ensuring the consistency of agent quality.

[0024] 2. In terms of cleaning and maintenance, this mixing tank exhibits significant advantages. The outer surface of the side scraper in the auxiliary component is in close contact with the inner wall of the medicine tank, the upper scraper is in close contact with the bottom of the screen, and the lower scraper is in close contact with the lower wall of the medicine tank. During the mixing process, residual medicine can be effectively scraped off from various places, reducing the adhesion of residual medicine in the tank. In addition, the screening frame of the filter component is precisely engaged with the slot on the upper part of the tank through the locking block. When it is necessary to clean or replace the screen, the screening frame can be easily and quickly removed, eliminating cleaning dead corners, reducing cleaning difficulty, saving cleaning time and costs, and contributing to the long-term stable operation of the equipment and the guarantee of hygiene and safety.

[0025] 3. In this utility model, the honeycomb screen of the filter component has a large filtration area, which can effectively prevent large or unqualified impurities from entering the stirring area when the raw materials of the medicine enter the tank, thus ensuring the purity of the stirred medicine from the source. At the same time, the efficient stirring and cleaning function avoids the contamination of the new batch of medicine by the residual medicine, thus comprehensively ensuring the quality of the medicine and meeting the needs of the pharmaceutical production industry for high-quality medicine.

[0038] In this embodiment, the driving device 8 includes a drive motor 81. The output end of the drive motor 81 passes through the fixing plate 10 and is fixedly connected to a main gear disk 88. A meshing disk 82 is meshed with the left side of the outer surface of the main gear disk 88. A connecting short shaft 87 is fixedly connected to the middle of the lower end of the meshing disk 82. A rotating rod 83 is fixedly connected to the middle of the upper end of the meshing disk 82. An auxiliary component 85 is fixedly connected to the upper and lower parts of the outer surface of the rotating rod 83. Two connecting shaft blocks 84 are fixedly connected to the middle of the outer surface of the rotating rod 83. A plurality of stirring blades 86 are fixedly connected to the outer surface of the connecting shaft block 84. The drive motor 81 is fixedly connected to the lower right side of the fixed plate 10. The auxiliary component 85 includes a fixed shaft 851, of which two are provided. Three upper scrapers 855 are fixedly connected to the outer surface of the upper fixed shaft 851, and three lower scrapers 852 are fixedly connected to the outer surface of the lower fixed shaft 851. A plurality of stirring rods 85 are fixedly connected to the upper ends of the three lower scrapers 852 and the lower ends of the three upper scrapers 855. 3. The lower ends of the three upper scrapers 855 on the upper side and the upper ends of the three lower scrapers 852 on the lower side are fixedly connected to side scrapers 854. There are three side scrapers 854. Two fixed shafts 851 are respectively fixedly connected to the upper part and the lower part of the outer surface of the rotating rod 83. The lower end of the connecting short shaft 87 is movably connected to the lower wall of the fixed plate 10 through a bearing. The lower part of the outer surface of the rotating rod 83 is movably connected to the bottom of the medicine tank 7. Several stirring blades 86 are all fan-shaped structures, and several stirring blades 86 are 20-angled. The cylinder is tilted at an angle, with several stirring rods 853 on the upper side and several stirring rods 853 on the lower side arranged in a ring around the rotating rod 83. The other ends of the stirring rods 853 on the upper side and several stirring rods 853 on the lower side do not contact the stirring blades 86. The outer surfaces of the three side scrapers 854 are in close contact with the inner wall of the medicine tank 7. The surfaces of the three upper scrapers 855 on the upper side are in close contact with the bottom of the screen 112, and the lower ends of the three upper scrapers 855 on the lower side are in close contact with the lower tank wall of the medicine tank 7.

[0039] Through the above scheme: the drive motor 81 serves as the power source, fixed to the lower right side of the fixed plate 10. Its output end passes through the fixed plate 10 and is fixedly connected to the main gear disk 88. After the drive motor 81 is started, it drives the main gear disk 88 to rotate at high speed. The left side of the outer surface of the main gear disk 88 meshes with the meshing disk 82, transmitting power to the meshing disk 82, causing the meshing disk 82 to rotate accordingly. The connecting short shaft 87 at the lower middle of the meshing disk 82 is movably connected to the lower wall of the fixed plate 10 through a bearing, ensuring the stability of the meshing disk 82 during rotation. At the same time, the rotating rod 83, which is fixedly connected to the middle of the upper end of the meshing disc 82, also begins to rotate. Several fan-shaped stirring blades 86, inclined at a 20-degree angle, are fixed to the middle of the outer surface of the rotating rod 83 via two connecting shaft blocks 84. During the rotation of the rotating rod 83, the stirring blades 86, utilizing their special shape and inclination angle, can efficiently stir the agent, increasing the contact area with the agent and improving stirring efficiency. The auxiliary components 85 at the upper and lower parts of the outer surface of the rotating rod 83 operate synchronously, and the two fixed shafts 851 of the auxiliary components 85 are respectively fixed... Fixed on the upper and lower parts of the outer surface of the rotating rod 83, the three upper scrapers 855 on the upper fixed shaft 851, the three lower scrapers 852 on the lower fixed shaft 851, and the three side scrapers 854 work together. The outer surface of the side scrapers 854 is in close contact with the inner wall of the medicine tank 7, the surface of the upper scrapers 855 is in close contact with the bottom of the screen 112, and the lower end of the lower scrapers 852 is in close contact with the lower tank wall of the medicine tank 7. When the rotating rod 83 rotates, it can effectively scrape off the residual medicine in the medicine tank 7 and the bottom of the screen 112, avoiding medicine waste and the effects of residual medicine on the environment. The subsequent stirring has an effect, and the stirring rods 853 on the upper scraper 855 and the lower scraper 852 are arranged in a ring around the rotating rod 83, with their other ends not in contact with the stirring blades 86. In this way, the stirring rods 853 and the stirring blades 86 can work together in different areas to stir the agent in all directions, further improving the uniformity of the agent mixture. The design of the entire drive device 8 realizes efficient stirring, cleaning and uniform mixing of the agent, which greatly improves the working performance and production efficiency of the agent mixing tank.

[0040] In this embodiment, the filter assembly 11 includes a screening frame 111, three locking blocks 113 are fixedly connected to the outer surface of the screening frame 111, and a screening mesh 112 is fixedly connected to the lower frame wall of the screening frame 111. The screening frame 111 is snapped onto the upper part of the inner wall of the medicine container 7. The positional dimensions of the three locking blocks 113 are matched one-to-one with the positional dimensions of the three slots 12. The screening mesh 112 has a honeycomb structure.

[0041] Through the above scheme: when the pharmaceutical raw material enters the pharmaceutical tank 7 from the middle of the upper part of the tank cover 6 through the feed pipe 4, the filter assembly 11 located on the upper part of the inner wall of the pharmaceutical tank 7 begins to function. The three locking blocks 113 fixed on the outer surface of the screening frame 111, because their position and size are adapted to the three locking slots 12 on the upper part of the inner wall of the pharmaceutical tank 7, can accurately lock into the locking slots 12, thereby stably fixing the screening frame 111 inside the upper part of the pharmaceutical tank 7. At this time, the raw material flows downward under the action of gravity and passes through the honeycomb structure screening mesh 112 fixed on the lower frame wall of the screening frame 111. The honeycomb structure screening mesh 112 has a large filtration area and can effectively filter the pharmaceutical raw material. Screening and filtration serves two purposes. First, it prevents larger or non-compliant impurities from entering the lower part of the reagent tank 7 and participating in the stirring, ensuring the quality of the stirred reagent. Second, compared to other ordinary filter structures, the honeycomb structure of the screen 112 ensures filtration accuracy while being less prone to clogging, allowing the raw materials to pass through more smoothly. Moreover, the screening frame 111 is engaged with the reagent tank 7 via the locking block 113 and the locking groove 12, making it easy and quick to remove the screening frame 111 from the reagent tank 7 when cleaning or replacing the screen 112, greatly improving the convenience of equipment maintenance and thus enhancing the working efficiency and stability of the entire reagent mixing tank.

[0042] It should be noted that this utility model is a pharmaceutical mixing tank. When the pharmaceutical mixing tank is working, firstly, the cover 5 is opened, and the pharmaceutical raw materials are added into the pharmaceutical tank body 7 from the middle of the upper end of the cover 6 through the feed pipe 4. During the process of entering, the raw materials will pass through the filter assembly 11 located in the upper part of the pharmaceutical tank body 7. The three locking blocks 113 on the outer surface of the screening frame 111 are precisely engaged with the three locking slots 12 on the upper part of the inner wall of the pharmaceutical tank body 7, ensuring that the screening screen 112 stably filters the pharmaceutical raw materials. Subsequently, the drive device 8 is started, and the drive motor 81 on the lower right side of the fixed plate 10 runs. Its output end passes through the fixed plate 10 and drives the main gear disk 88 to rotate. The meshing disk 82 connected to the left side of the outer surface of the main gear disk 88 rotates accordingly. The connecting short shaft 87 in the middle of the lower end of the meshing disk 82 rotates stably on the lower wall of the fixed plate 10 through the bearing. The rotating rod 83 at the upper center of the meshing disc 82 starts to rotate. Several fan-shaped stirring blades 86 with an 80-degree inclination are fixed to the middle of the outer surface of the rotating rod 83 by two connecting shaft blocks 84, which efficiently stir the agent. The auxiliary components 85 at the upper and lower parts of the outer surface of the rotating rod 83 operate synchronously. The upper scraper 855, lower scraper 852 and side scraper 854 on the two fixed shafts 851 scrape and clean the inner wall of the agent tank 7, the bottom of the screen 112 and the lower tank wall of the agent tank 7 to prevent agent residue. The stirring rods 853 on the upper scraper 855 and lower scraper 852 are arranged in a ring and are opposite each other, working together with the stirring blades 86 to stir the agent in all directions. After stirring is completed, the valve on the discharge pipe 9 is opened and the stirred agent is discharged from the lower left part of the agent tank 7.
