Description

Technical Field

[0001] The utility model belongs to the field of preparation tanks, and particularly relates to a preparation tank for a sustained-release coating premix. Background Art

[0002] Currently, film coating powder, namely film coating premix, is a raw material for film coating. It is a premix in which various components are scientifically and reasonably formulated, and some components need to be pretreated and fully mixed. When in use, the coating powder is dissolved in a suitable solvent and then sprayed on tablets to form film-coated tablets.

[0003] For example, the application number: "CN202120729540.9", a mixing device for coating sustained-release agent processing. The utility model discloses a mixing device for coating sustained-release agent processing, which includes a mixing barrel. A premixing barrel is arranged above the mixing barrel. The discharge port at the bottom of the premixing barrel is communicated with the feed port of the rotary cover arranged at the top of the mixing barrel through a connecting pipe. The rotary cover is coaxially arranged with the mixing barrel and is rotationally connected. The feed port is eccentrically arranged on the rotary cover. A rotating mechanism for driving the rotary cover to rotate is arranged on the mixing barrel; the discharge port of the premixing barrel is coaxially arranged with the mixing barrel, and the top of the connecting pipe is rotationally connected with the discharge port of the premixing barrel; a stirring mechanism I is arranged inside the premixing barrel, and a stirring mechanism II is arranged inside the mixing barrel; a feed pipe is arranged at the upper part of the mixing barrel, and a discharge port is arranged at the bottom of the mixing barrel. The mixing device for coating sustained-release agent processing with the above structure can solve the problem of uneven mixing of raw materials.

[0004] However, referring to the above patent and the prior art, it is known that when the existing preparation tank mixes the premix, during feeding, a batch feeding structure is mostly directly adopted for feeding. However, in this feeding method, since the powder raw materials in the premix are lighter and will float on the liquid premix during feeding, sufficient and effective mixing cannot be carried out, and it is easy to cause caking.

[0005] Therefore, in view of the deficiencies of the above solutions in actual production and implementation, they are corrected and improved. At the same time, with the spirit and concept of pursuing excellence, and with the assistance of professional knowledge and experience, and after various ingenious ideas and tests, the present utility model is created. A preparation tank for a sustained-release coating premix is provided to solve the problem that when feeding, a batch feeding structure is mostly directly adopted, but in this feeding method, since the powder raw materials in the premix are lighter and will float on the liquid premix during feeding, sufficient and effective mixing cannot be carried out, and it is easy to cause caking.
