The utility model relates to the technical field of silica sol filtering, and provides an ion exchange method silica sol filtering device which comprises a bottom plate, the top of the bottom plate is fixedly connected with a filtering box, and a grease pressing layer, a liquid discharging assembly and a resin layer are sequentially arranged in the filtering box from top to bottom; one side of the inner wall of the filter box is fixedly connected with an activated carbon fiber filter membrane, and one side of the filter box is fixedly connected with a circulating pump. Silica sol added into the filter box is filtered through the grease pressing layer and the resin layer, solid-liquid ion exchange occurs on an interface between solid particles and liquid, some ions in the silica sol react with ion exchange resin, the silica sol is filtered, and the silica sol is filtered. Under the action of the circulating pump, the silica sol in the filter box is conveyed to the upper part of the interior of the filter box t
