High-capacity injection preparation device

The utility model relates to the technical field of injection preparation, in particular to a large-capacity injection preparation device, and aims to solve the problems that the quality of an injection is influenced by the fact that concentrated preparation and diluted preparation of an existing liquid preparation device are completed in the same liquid preparation tank, and stirring force needed during concentrated preparation and diluted preparation is different. In order to overcome the defects that thick preparation and thin preparation in an existing liquid preparation tank are stirred through the same stirring mechanism, and the optimal stirring effect is difficult to obtain, the following scheme is provided: the liquid preparation tank comprises a base, a box body is fixedly connected to the base, a liquid preparation device is arranged at the top of the box body, and the liquid preparation device is connected with a thick preparation box; according to the device, the same amount of raw materials, aux
