According to news from the financial industry on July 5, 2024, Tianyancha’s intellectual property information shows that Anhui Yishitong Material Technology Co., Ltd. applied for a project called “A high-temperature resistant ceramic filter material preparation method and its preparation system”. Publication number CN202410397938.5, application date is April 2024.
The patent abstract shows that the present invention discloses a method for preparing high-temperature resistant ceramic filter materials, which is prepared from the following mass fractions of raw materials: silicon carbide sand 70-80%, kaolin 1-3%, metallic silicon powder 6-10%, Additive 1-3%, binder 8-12%, including the following steps: S1: put kaolin, metal silicon powder, and additives into ball mill 1 for dry ball milling until the particle size is no more than 20 μm to obtain small materials; S2 : Add silicon carbide sand into mixer 2, then add binding agent, mix evenly, then add small ingredients and mix evenly to obtain a mixed material; S3: Stamp the mixed material for 30-72 hours. In the present invention, by adding a feeding mechanism, the sintered ceramic filter is fixed on the material clamping mechanism, and then is sent to the position of the cleaning and drying machine through the rotation of the feeding ring, and the ceramic filter is cleaned and dried through the cleaning and drying machine. It can effectively remove impurities and pollutants remaining on ceramic filters during the production process and improve the quality of ceramic filters.
