Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical mixing devices, in particular to a pharmaceutical powder mixing device. Background Art

[0002] Pharmaceutical powder mixers play a crucial role in the booming modern pharmaceutical industry. Pharmaceutical preparations are often carefully blended from a variety of powdered raw materials, each with its own distinct physical, chemical, and pharmacological properties. Pharmaceutical powder mixers, through their specific mechanical structure and operating principles, enable the thorough and uniform mixing of these various powders within a closed, precisely controlled environment.

[0003] The patent document with the prior art announcement number CN213254110U provides a pharmaceutical powder trough mixer, comprising a mixing box and a base, a rotating assembly is provided between the bottom of the mixing box and the base, a stirring shaft is coaxially provided inside the mixing box, a switch door is hinged on the side wall of the mixing box, a plurality of stirring rods arranged radially along the stirring shaft are vertically fixed to the stirring shaft located in the mixing box, and a horizontal scraper is slidably sleeved on the stirring rods on the same side. The utility model provides a scraper equipped with a lifting assembly on the stirring shaft, which facilitates the scraping of materials attached to the inner wall of the mixing box during the use of the pharmaceutical powder trough mixer, so that the materials are evenly mixed in the mixing box, solving the problem that the materials attached to the inner wall of the mixing box cannot be evenly mixed, thereby improving the mixing quality of the powder. In addition, by providing a rotating assembly on the outer wall of the mixing box, it is convenient to unload the materials after mixing, which is highly practical.

[0004] However, in the use of the existing pharmaceutical powder mixing device, since the pharmaceutical powder usually has a small particle size, it is easy to adsorb and agglomerate with each other due to static electricity during the mixing process, and the powder mixing device is also adsorbed on the inner wall of the mixing device due to static electricity. Since the powder mixing device cannot eliminate the static electricity, the mixing effect is poor and the cleaning difficulty is increased. When cleaning the powder mixing device, there are dead corners inside the powder mixing device, and when water is added for cleaning, the water cannot rinse some positions, resulting in incomplete cleaning. For this reason, we propose a pharmaceutical powder mixing device. Utility Model Content

[0016] (3) Beneficial effects

[0017] The utility model provides a pharmaceutical powder mixing device, which has the following beneficial effects:

[0018] (1) During the use of this pharmaceutical powder mixing device, the staff adds the pharmaceutical powder into the mixing tank through the feeding hopper, and then the staff starts the stirring motor, which drives the stirring rod on the stirring shaft to rotate. At this time, the stirring rod will stir the pharmaceutical powder. During the stirring, the static eliminator will also start to operate and apply high voltage to the ion needle. Due to the tip effect, the electric field strength at the tip of the ion needle is extremely high, so that the surrounding air molecules are ionized and a large number of positive and negative ions are generated, thereby eliminating the electrons in the pharmaceutical powder, thereby preventing the phenomenon of static adsorption on the inner wall of the mixing device and the agglomeration of powder, so that the pharmaceutical powder can be fully mixed together, thereby improving the stirring efficiency and reducing the difficulty of cleaning.

[0019] (2) After the pharmaceutical powder mixing device is stirred, when it is necessary to discharge the powder, the staff starts the discharge rod, which drives the sealing valve to contract and open the discharge pipe, and then the powder enters the discharge pipe and is discharged from the discharge pipe. When cleaning is required after unloading, the staff connects the water pipe to the water inlet pipe, and the water flows into the rotating flange and into the stirring shaft through the water inlet. The water will be sprayed on the inner wall of the mixing tank through the water spray port. At the same time, the stirring motor drives the stirring shaft to rotate so that the water is fully sprayed on the inner wall of the mixing tank, thereby cleaning the mixing tank, thereby improving the cleaning effect.
