Description

Technical Field

[0001] The invention relates to a central support of a polymer filtering device. Background Art

[0002] After filtration, polymers tend to re-form and aggregate, and over time they will accumulate on the filter screen and filter bracket. Existing filter brackets are all cylindrical mesh iron brackets without flow-guiding function. After the liquid passes through the filter screen, convection will form on the cylindrical bracket, resulting in a long residence time and re-aggregation, which not only affects the filtration accuracy but also shortens the service life of the filter. Summary of the invention

[0003] 1. Technical issues to be resolved

[0004] In order to solve the above problems, the present invention proposes a central bracket of a polymer filtration device. Not only does the bracket itself have a flow-guiding structure, but the surface is also sprayed with a coating with good fluidity, which solves the residence time of the polymer in the filter and reduces the possibility of re-agglomeration.

[0005] (II) Technical solution

[0006] A central support of a polymer filtering device of the present invention comprises: a frame and a coating sprayed on the surface of the frame; the frame is a solid column made of metal material, and a mounting platform for mounting a cylindrical filter screen is provided at one end of the frame; a docking platform is provided at the other end of the frame, and a liquid outlet is provided on a threaded column extending forward of the docking platform; the section between the mounting platform and the docking platform of the frame is a guide section; a plurality of groups of guide grooves are provided in an array at equal intervals around the cylindrical frame located in the guide section, and support bars for supporting the cylindrical filter screen are left between adjacent guide grooves; the depth of the guide groove gradually deepens from the mounting platform toward the docking platform; a collecting hole is provided on the groove surface of the guide groove located at the end of the docking platform, and the collecting hole converges to the liquid outlet; the coating is sprayed on the surface of the guide section and the surface of the collecting hole of the frame by thermal spraying or plasma sputtering spraying.

[0007] Furthermore, the angle between the central axis of the collecting hole and the central axis of the frame is 25° to 38°; the edges and corners between the collecting hole wall and the guide groove wall are rounded by grinding.

[0008] Furthermore, a threaded hole is provided at the center of the mounting platform.

[0009] Furthermore, the diameter of the mounting platform is equal to the diameter of a circle surrounded by a plurality of support bars.

[0010] Furthermore, the coating material is a ceramic coating or an alumina coating.

[0011] (III) Beneficial effects

[0012] 1. The central support of a polymer filtering device of the present invention replaces the through-hole hollow support of a traditional cylindrical polymer flow meter with a solid column support, and digs a guide groove around the support and a collecting port that cooperates with the guide groove, so that the liquid polymer can quickly flow out of the filter through the guide after filtration and is not easy to re-form and agglomerate; the stability of filtration is improved, and the service life of the filter is indirectly increased.

[0013] 2. The central support of a polymer filter device of the present invention can improve the flow-guiding performance by spraying a coating with good fluidity, such as a ceramic coating, on the flow-guiding surface of the support body. BRIEF DESCRIPTION OF THE DRAWINGS
