Description

Technical Field

[0001] The utility model relates to the technical field of metal braided mesh filter discs, in particular to a metal braided mesh filter disc of composite metal powder. Background Art

[0002] Metal woven mesh filter, also known as metal mesh, is made by combining different numbers of metal meshes with support meshes and through the edging process. It is mainly used for filtering, screening and separation processes in various industrial fields. Metal woven mesh filter is not convenient to use alone. In most cases, it is often used with a cylindrical bracket to form a metal woven mesh filter tube structure.

[0003] The traditional metal woven mesh filter and the cylindrical bracket form a metal woven mesh filter tube structure. During use, the filtering effect is poor due to the large filter holes. In addition, under high pressure environment, the filter material can easily cause the filter to deform, thus affecting the filtering effect. In most cases, the metal woven mesh filter is fitted on the cylindrical bracket to form a cylindrical shape, and then the two ends of the metal woven mesh filter are welded to complete the connection and welded together with the cylindrical bracket. This method is quite inconvenient when replacing the metal woven mesh filter later.

[0004] Therefore, a metal woven mesh filter of composite metal powder is proposed. Utility Model Content
