Description

Technical Field

[0001] The utility model belongs to the technical field of metal nano powder preparation, in particular to a filter used for metal nano powder preparation. Background Art

[0002] Metallic sodium rice powder refers to micron-sized powder made of metallic sodium, which is a common alkali metal with a silvery-white metallic luster and is solid at room temperature and pressure. Metallic sodium has important applications in many chemical and industrial processes, such as as a reducing agent in organic synthesis reactions, and in the preparation of organometallic compounds and other compounds.

[0003] In the prior art, in the process of preparing metal nanopowder, the solution containing metal nanopowder is filtered by using a filter membrane. However, when filtering by using the filter membrane, the solution containing metal nanopowder will always flow to the same position of the filter membrane, resulting in excessive metal nanopowder particles being accumulated. Although the accumulated metal nanopowder particles will flow to other positions of the filter membrane, this will affect the filtering effect of the filter membrane. In severe cases, the filter membrane will be scrapped prematurely and cannot filter the solution containing metal nanopowder for a long time. To this end, we provide a filter for preparing metal nanopowder to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a filter for preparing metal nanopowder. Through the coordinated arrangement of a drainage component and a pushing component, the problem in the prior art that a solution containing metal nanopowder always flows to the same position of a filter membrane, causing excessive metal nanopowder particles to accumulate and affecting the filtration of the filter membrane is solved.

[0016] The utility model has the following beneficial effects:

[0017] 1.
