Description

Technical Field

[0001] This utility model belongs to the field of rifamycin production technology, specifically relating to a dosing and stirring tank for rifamycin production. Background Technology

[0002] Rifamycin is a class of antibiotics with important antibacterial activity. In the production process, the mixing step is crucial and directly affects the product quality and production efficiency of rifamycin.

[0003] Traditional rifamycin production tanks typically employ only a single stirring method, resulting in poor mixing efficiency. This leads to incomplete mixing of the drug and raw materials, resulting in insufficient reaction and reduced rifamycin yield and quality. Furthermore, during stirring, materials tend to adhere to the inner wall of the tank, causing waste and affecting its normal operation and lifespan. In addition, the traditional tank design hinders comprehensive stirring and cleaning, failing to meet the demands of modern rifamycin production.

[0004] Therefore, it is necessary to design a new type of dosing and mixing tank for rifamycin production to solve the above problems and improve the production quality and efficiency of rifamycin. Utility Model Content

[0005] To address the problems mentioned in the background section, this invention provides a dosing mixing tank for rifamycin production. This solves the problems of poor mixing effect, material adhesion to the inner wall, and difficulty in comprehensive mixing and cleaning of traditional mixing tanks, thereby improving the quality and efficiency of dosing mixing in the rifamycin production process.

[0006] Overall structure: A dosing and mixing tank for rifamycin production includes a support and a mixing tank, and also includes an external stirring assembly mounted on the support, the external stirring assembly being connected to the mixing tank, and an internal stirring assembly mounted on the mixing tank, the internal stirring assembly including an internal stirring mechanism and a wall scraping mechanism.

[0007] External stirring assembly: The external stirring assembly includes a motor bracket fixed on a support frame and a pair of bearing seats. A motor is mounted on the motor bracket, and a drive wheel is fixedly mounted on the motor's output shaft. A rotating shaft is movably mounted on the pair of bearing seats. A driven wheel is fixedly mounted at one end of the rotating shaft, and the other end is fixedly connected to the stirring tank. The drive wheel and the driven wheel are connected by a belt. After the motor starts, the drive wheel, belt, and driven wheel drive the rotating shaft to rotate, thereby causing the entire stirring tank to rotate, achieving the external stirring function.

[0008] Internal stirring mechanism: The internal stirring mechanism includes a first motor fixed to the mixing tank, and a stirring rod is mounted on the output shaft of the first motor through the side wall of the mixing tank. The stirring rod is equipped with three convex discs, and three spiral stirring blades are arranged between the three convex discs. The first motor drives the stirring rod to rotate, and the spiral stirring blades stir the material inside the mixing tank, enhancing the stirring effect.

[0009] Wall scraping mechanism: The wall scraping mechanism includes a sliding hole formed in the spiral stirring blade, and a sliding rod is provided inside the sliding hole. A limit plate is provided at one end of the sliding rod, and a rubber scraper is fixedly provided at the other end. A spring is sleeved on the sliding rod between the rubber scraper and the spiral stirring blade. During the stirring process, the rubber scraper remains in contact with the inner wall of the mixing tank under the action of the spring. As the stirring rod rotates, the rubber scraper scrapes off the material adhering to the inner wall, preventing material accumulation.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] Excellent mixing effect: The external stirring component makes the mixing tank rotate as a whole, while the internal stirring mechanism stirs the materials inside the tank. The combination of internal and external stirring greatly improves the degree of mixing of materials, allowing the drug and raw materials to react fully, thus improving the production quality and efficiency of rifamycin.

[0012] Preventing material adhesion: The scraping mechanism can promptly scrape off the material adhering to the inner wall of the mixing tank, avoiding material waste and ensuring the normal operation and service life of the mixing tank.

[0013] Reasonable structure: The connections and fits between the components are tight, the design is scientific and reasonable, it is easy to operate and maintain, and it can meet the needs of modern rifamycin production. Attached Figure Description
