Description

Technical Field

[0001] This utility model relates to the field of ceramic parts, and more particularly to ceramic parts resistant to high temperature and high heat. Background Technology

[0002] In the chemical industry, the materials used to manufacture ceramic flanges are primarily based on their corrosion resistance and high-temperature resistance. Common types include alumina ceramics, silicon carbide ceramics, and silicon nitride ceramics. Alumina ceramics possess excellent chemical stability, resisting corrosion from various acids and alkalis; higher-purity alumina ceramics perform even better in chemical environments. Silicon carbide ceramics not only have excellent corrosion resistance but also high thermal conductivity, making them advantageous in chemical processes requiring heat dissipation, such as at the connection points of high-temperature chemical reactors.

[0003] However, when using flange connections, there is no device for filtering the liquid inside the flange. As a result, when there are impurities in the liquid, these impurities will enter the ceramic tube, causing scratches on the inner wall of the ceramic tube and greatly reducing the service life of the ceramic tube. In order to address this technical problem, this application proposes a high-temperature and high-heat resistant ceramic component. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-temperature and high-heat resistant ceramic component. By incorporating a filter plate, it can filter the liquid transported in the pipeline, thereby preventing impurities in the liquid from entering the ceramic pipe and causing scratches on the inner wall of the ceramic pipe, thus extending the service life of the ceramic pipe. By installing a sealing ring on the filter plate, it can improve the sealing performance of the ceramic flange connection, preventing liquid leakage from the connection of the ceramic flange and ensuring the safety of operators and the surrounding environment.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] High-temperature and high-heat resistant ceramic components include a ceramic tube, a ceramic flange fixedly connected to the outer wall of the ceramic tube, a threaded opening on the outer wall of the left end of the ceramic tube, an installation groove on the inner wall of the ceramic flange, a filter plate arranged on the inner circumference of the ceramic flange, multiple springs arranged at the rear end of the filter plate, and sealing rings arranged at both the front and rear ends of the filter plate.

[0007] Furthermore, the mounting groove includes a spring groove located on the inner wall of the ceramic flange, and a bolt hole is provided at the rear end of the spring groove, wherein the diameter of the bolt hole is smaller than that of the spring groove.

[0008] Furthermore, multiple bolts are provided before and after the sealing ring at the front end.

[0009] Furthermore, mounting holes are provided on the outer periphery of both the sealing ring and the filter plate.

[0010] Furthermore, the ceramic tube and ceramic flange include a base layer, a transition layer, and a surface coating.

[0011] Furthermore, the substrate layer is made of zirconium oxide, which has good toughness and thermal insulation properties.

[0012] Furthermore, the transition layer is made of titanium aluminum, which has good high-temperature strength and oxidation resistance.

[0013] Furthermore, the surface coating is made of silicon molybdenum, which can effectively prevent the substrate layer from being oxidized.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, by setting a filter plate, the liquid transported in the pipeline can be filtered, thereby preventing impurities in the liquid from entering the ceramic tube and causing scratches on the inner wall of the ceramic tube, thus extending the service life of the ceramic pipe.
