Technical Field

[0001] This utility model relates to the field of pharmaceutical equipment, and in particular to pharmaceutical equipment for mixing pharmaceutical powders. Background Technology

[0002] Pharmaceutical powder mixing equipment is typically made of stainless steel to meet the hygiene standards of the pharmaceutical industry and is equipped with a sophisticated control system to precisely adjust parameters such as mixing speed, time, and temperature. Depending on different process requirements and material characteristics, pharmaceutical powder mixing equipment can be designed in different forms, such as V-type mixers, double cone mixers, or three-dimensional motion mixers, thus making it suitable for pharmaceutical companies of all sizes to carry out efficient and rapid pharmaceutical powder mixing operations.

[0003] In the pharmaceutical manufacturing process, because pharmaceutical powders often have a certain degree of adhesion, after the mixing operation is completed, the material is easy to remain in the gaps of the stirring shaft and its surroundings, which is difficult to clean thoroughly. This residue may not only lead to cross-contamination, affecting the quality and purity of the next batch of medicines, but also puts forward higher requirements for equipment maintenance.

[0004] Therefore, in the pharmaceutical process, after the mixing operation, the powder material is easily left in the gaps of the stirring shaft and its surroundings, which is difficult to clean thoroughly. This residue may not only cause cross-contamination and affect the quality and purity of the next batch of medicines, but also allows for the design of pharmaceutical powder mixing equipment with an easily detachable stirring rod. Utility Model Content

[0005] In order to overcome the problem that after the mixing operation is completed in the pharmaceutical process, the powder material is easy to remain in the gaps of the stirring shaft and its surroundings, which is difficult to clean thoroughly.

The fixing blocks 8 are fixedly connected to the turntable 4. A stirring plate 7 is fixedly connected to the outer surface of the stirring rod 5. A groove 10 is formed inside the fixing blocks 8, and the stirring rod 5 has a corresponding groove 10. Protective boxes 25 are slidably connected to the left and right sides of the bottom of the tank cover 2, and a piston 11 is fixedly connected inside the protective box 25. The output end of the piston 11 passes through the protective box 25 and is fixedly connected to the pusher block 9. Push block 9 is slidably connected to groove 10, turntable 4 is fixedly connected to protective box 25, sealing ring 6 is rotatably connected to the bottom of mixing barrel 1, stirring rod 5 is movably connected to sealing ring 6, stirring rod 5 is movably connected to mixing barrel 1, empty groove 12 is opened inside the bottom of mixing barrel 1, multiple long grooves 13 are opened at the bottom of mixing barrel 1, and two limit rods 14 are fixedly connected to the top of mixing barrel 1. If excess powder enters empty groove 12, it can be removed through long groove 13. By starting piston 11, push block 9 is moved, so that push block 9 moves out from fixed block 8 and stirring rod 5. Then open barrel cover 2 and remove barrel cover 2 from mixing barrel 1. Then pull stirring rod 5 out from sealing ring 6. Then clean the inside of mixing barrel 1 and reinstall clean stirring rod 5 to prevent powder residue on stirring rod 5 and save cleaning time.

[0019] Please see Figures 1-5In this embodiment, the limiting rod 14 is slidably connected to the lid 2. Two handles 15 are fixedly connected to the top of the lid 2. Fixing plates 16 are fixedly connected to the left and right sides of the lid 2 respectively. By pulling the lid 2 on the limiting rod 14 through the handles 15, the lid 2 is lifted up to prevent the stirring plate 7 from scratching the inner wall of the mixing tank 1. Bolts 17 are threadedly connected to the inside of the fixing plate 16 and are threadedly connected to the mixing tank 1. Rotating rods 18 are fixedly connected to the left and right sides of the mixing tank 1 respectively. The fixing plate 16 is connected to the mixing tank 1 by the bolts 17 to fix the position of the lid 2. The end of the rotating rod 18 away from the mixing tank 1 is rotatably connected to a support. The left end of the support frame 19 is fixedly connected to a motor 20. The output end of the motor 20 is fixedly connected to a rotating rod 18. The motor 20 drives the rotating rod 18 and the mixing barrel 1 to shake on the support frame 19 for mixing. The front end of the mixing barrel 1 is provided with an empty slot 24.

The front side of the mixing barrel 1 is fixedly connected to a piston 22. The upper end of the piston 22 is fixedly connected to a baffle 23. The baffle 23 is slidably connected to the mixing barrel 1. The piston 22 drives the baffle 23 to move and seal the empty slot 24 to prevent the powder from leaking out.

[0020] During operation, the fixing plate 16 is connected to the mixing tank 1 and the fixing lid 2 via bolts 17. The powder is fed and discharged through the inlet / outlet frame 21. During mixing, the piston 22 drives the baffle 23 to move and seal the empty trough 24 to prevent the powder from leaking out. At the same time, the motor 20 drives the rotating rod 18 and the mixing tank 1 to shake on the support frame 19 for mixing. The motor 3 drives the stirring rod 5 to rotate for mixing. When it is necessary to clean the mixing tank 1, the piston 11 is activated to drive the pusher 9 to move, so that the pusher 9 moves out from the fixing block 8 and the stirring rod 5, and then the lid 2 is opened. Remove the lid 2 from the mixing tank 1, then pull the stirring rod 5 out of the sealing ring 6. Clean the inside of the mixing tank 1 and reinstall the clean stirring rod 5. This prevents powder residue from the stirring rod 5 and saves cleaning time. When opening the lid 2, you can pull the lid 2 upward on the limit rod 14 by the handle 15 to prevent the stirring plate 7 from scratching the inner wall of the mixing tank 1. If any excess powder enters the empty trough 12 during cleaning, it can be removed through the long trough 13. The vibration motor can increase work efficiency during cleaning and discharging.

[0021] Through the above steps, when it is necessary to clean the mixing tank 1, the piston 11 is activated to drive the pusher 9 to move, so that the pusher 9 moves out from the fixed block 8 and the stirring rod 5. Then, the tank cover 2 is opened and removed from the mixing tank 1. Then, the stirring rod 5 is pulled out from the sealing ring 6. Then, the inside of the mixing tank 1 is cleaned and the clean stirring rod 5 is reinstalled. This prevents the stirring rod 5 from having any powder residue and saves cleaning time. This solves the problem that after the mixing operation, the powder is easy to remain in the gaps of the stirring shaft and its surroundings, which is difficult to clean thoroughly. This residue may not only cause cross-contamination, but also affect the quality and purity of the next batch of medicine.
