[0024] In this embodiment, the screening shell 102 is fixedly connected to the top of the base 101, serving as the operating space for the entire screening process; the feed pipe 103 is arranged at the top of the screening shell 102 and is used to introduce the ceramic frit raw materials to be screened into the interior of the screening shell 102. Inside the screening shell 102, a rotatable support rod 105 is provided and is driven to rotate by a rotating motor 104. A plurality of inclined scraping plates 106 are evenly arranged and fixedly installed on the support rod 105. As the support rod 105 rotates, these inclined scraping plates 106 can continuously scrape the material during the screening process, preventing the material from accumulating or blocking the filter screen 108, thereby improving the screening efficiency and quality. At the bottom of the screening shell 102, a slidable support cylinder 107 is provided, and a plurality of filter screens 108 with different apertures are fixedly installed on the support cylinder 107, forming a multi-stage screening structure. Each filter screen 108 is arranged corresponding to the position of one or more inclined scraping plates 106 to ensure that the material can be fully dispersed during the screening process and is classified and screened through the corresponding filter screen 108.
