Description

Technical Field

[0001] The utility model belongs to the technical field of swing granulators, and in particular relates to a screen fixing device of a swing granulator. Background Art

[0002] Granulation is the process of processing materials in the state of powder, melt, aqueous solution, etc. into granules with a certain shape and size. In pharmaceutical production, granulation methods are mainly divided into wet granulation, dry granulation and spray granulation, among which wet granulation is the most widely used. In the process of wet granulation, a swing granulator is often used to make wet drug powder into granules. The swing granulator mainly includes a machine body, a hopper, a granulation box, and a screen; a drum is provided in the granulation box, and the screen is located at the bottom of the drum. When working, the mechanical transmission system inside the machine body drives the drum to rotate in the forward and reverse directions, thereby producing an extrusion and shearing effect on the wet material, and squeezing the material through the screen into granules.

[0003] As an essential part of the swing granulator, the screen has an important impact on the efficiency of the swing granulator. At the same time, the screen is also a wearing part in the swing granulator and needs to be replaced frequently. When replacing, the screen fixing device needs to be removed and then installed on the machine body after the replacement is completed, which greatly reduces the efficiency of the swing granulator. In addition, when replacing the screen, the screen fixing device of the prior art needs to replace the used screen as a whole, which increases the loss cost of the screen. Utility Model Content
