Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical production technology, specifically to a mixing tank for the production of pharmaceutical intermediates. Background Technology

[0002] Pharmaceutical intermediates are chemical substances produced as intermediate products during the manufacturing process of pharmaceuticals. These intermediates can sometimes be used directly as drugs, but more commonly they are used for further chemical reactions. Ingredients play a crucial role in the production of pharmaceutical intermediates.

[0003] Patent document CN218107357U discloses a mixing tank for pharmaceutical intermediate production, comprising a tank body and a stirring unit. The tank body has a top cover bolted to its upper end, with a dust cover hinged to a cleaning hole on the top surface of the cover. A discharge pipe is located at the discharge hole at the lower end of the tank body. A jacket is provided outside the tank body, with uniformly distributed heating tubes at the lower end of the jacket. The input end of the heating tubes is electrically connected to the output end of an external control unit. The stirring unit is located inside the tank body, with its upper end fixedly connected to the upper surface of the top cover. The stirring unit includes a main stirring rod, a first impeller, and a second impeller. The main stirring rod is rotatably connected to the inside of the tank body via a sealed bearing, and its upper end is rotatably connected to an oblique hole on the upper surface of the top cover via a sealed bearing. The main stirring rod is not parallel to the central axis of the tank body. This mixing tank for pharmaceutical intermediate production has high stirring efficiency, good heating uniformity, and high production quality. However, this patent still has the following problems in actual use:

[0004] The addition of materials to this mixing tank is inconvenient due to the top cover. Furthermore, the single-pour method of adding materials causes them to pile up, resulting in low mixing efficiency. While the mixing tank uses a stirring rod, blades one and two to achieve mixing, the limited angles of these components further reduce its overall mixing efficiency.

[0005] Therefore, a mixing tank for the production of pharmaceutical intermediates is proposed to solve the problems mentioned above. Utility Model Content
