Description

Technical Field

[0001] The utility model relates to the technical field of hemodialysis dry powder, in particular to a screening device for hemodialysis dry powder. Background Art

[0002] The Chinese patent document with the existing announcement number CN116850865A discloses a dry powder screening and mixing device, which proposes that the hemodialysis fluid is prepared by mixing powdered raw materials with a solution. The mixed powder can also be prepared in advance and packaged and distributed to the hospital for mixing with the solution. In the mixing process of the powdered raw materials, the transportation and storage of the raw materials will cause the powdered raw materials to agglomerate. The existing mixing equipment does not have the function of screening and further processing the powdered raw materials, and requires additional steps for processing, which is time-consuming and labor-intensive, and reduces production efficiency. The agglomerated raw materials enter the mixing equipment. After that, it will affect the full mixing of raw materials and affect product quality. There is room for improvement. The solution is to set up a dust-raising structure, which can lift the dry powder inside the mixing tank entering from the feed plate and preliminarily mix it in the air, and then drop it onto the screening mechanism. The conical screening net can screen out the agglomerated materials and accumulate them on the accumulation platform for subsequent processing. At the same time, during the screening process, the materials on it can also be preliminarily mixed. Finally, a rolling structure is set to roll the block dry powder on the accumulation platform under the drive of the mixing shaft, and then screen it into the stirring and mixing chamber to complete the screening and mixing processes.

[0003] The above scheme and the prior art screen the hemodialysis dry powder through a conical screening net. During use, the accumulation of agglomerated materials may cause the conical screening net to become blocked, which affects the screening of the hemodialysis dry powder and cannot meet actual use requirements.

[0004] Therefore, the utility model proposes a screening device for hemodialysis dry powder to solve the above problems. Utility Model Content
