Abstract

The invention discloses a nano-aperture metal filter element and a preparation method thereof. The nano-aperture metal filter element comprises a filter material, an end cover located at the opening end of the filter material and a chuck, a convex positioning part is formed at the end of the filter material, the end cover and the chuck are located on the two sides of the positioning part respectively, and the positioning part is fixed between the end cover and the chuck. A sealing component is arranged between the end cover and the positioning part. During preparation, the filter material, the end cover, the chuck, the sealing component and other auxiliary materials can be separately processed without welding, so that a user can select different components for combined use according to use requirements, and can independently replace and use a component after the part of the components are damaged without completely replacing the components, the use cost of the filter element is reduced, and meanwhile, the filter element also has extremely high sealing performance and an extremely good use effect.

Description

technical field

[0001] The invention relates to the technical field of metal filter elements, in particular to a nano-aperture metal filter element and a preparation method thereof. Background technique

[0002] Metal powder sintered nano-pore filter elements are widely used in many fields because of their good high temperature resistance, oxidation resistance, corrosion resistance and other properties. Due to the limitation of the use environment of this type of filter element, the end cover cannot be connected with the filter material by gluing, because if the connection is made by gluing, when the filter element is used in an environment with a slightly higher temperature and pressure , The filter core rubber is easy to break, causing the end cap to separate from the filter material. For this, welding is generally used to connect the end cap and filter material.

[0003] However, the welding connection between the end cover and the filter material depends entirely on the...
