Filter disc with sealing structure for filter

The utility model relates to the technical field of filtering devices, in particular to a filter disc with a sealing structure for a filter, which is characterized in that filter disc main bodies are arranged in a stacked manner, filtrate enters a second accommodating cavity through water inlet holes, and the filtrate in the second accommodating cavity permeates into a first accommodating cavity on the lower side through annular filter paper, so that the filter disc main bodies are sealed; the first filtering is realized; then the filtrate flows to the back surface (namely, the second accommodating cavity) of the filter disc main body on the lower side through the communicating groove, and permeates into the first accommodating cavity on the lower side of the filter disc main body through the filter paper on the lower side of the filter disc main body, and the operation is repeated, so that the effect of filtering for multiple times is realized, and the filtering effect of the filtrate is better. 本实用新型涉及过滤装置技
