Description

Technical Field

[0001] The utility model relates to the technical field of vibrating screens, in particular to a powder vibrating screen for medicine. Background Art

[0002] The powder vibrating screen for medicine is mainly used for screening and filtering various powdery medicines, such as fine powder, micro powder, and dry and wet materials, etc. It is a high-precision screening device that filters and screens the medicine powder through an oscillating sieve block in multiple stages.

[0003] At present, the more popular vibrating screens on the market are composed of a hopper, an oscillation chamber, a coupling, and a motor. The oscillation chamber is composed of an eccentric wheel, a rubber software, a main shaft, bearings, etc. The adjustable eccentric weight is driven by a motor to reach the center line of the main shaft, and generates a centrifugal force under an unbalanced state, changing the strength of the material and forming an orbital vortex in the sieve. The amplitude of the weight regulator can be adjusted according to different materials and sieve blocks.

[0004] However, in the actual practical process, during long-term use, some medicine powders may have a certain viscosity and agglomerate during the oscillation process, accumulating and adhering to the inner wall of the sieve body or the surface of the sieve block, affecting the screening efficiency. And the vibrating screens in the existing technology do not have a structure for quickly cleaning the medicine powder accumulated and adhered to the inner wall of the sieve body or the surface of the sieve block. When the accumulated and adhered medicine powder agglomerates, it can only be disassembled for cleaning, which is extremely inconvenient. Summary of the Utility Model
