The invention relates to the technical field of continuous casting machine auxiliary equipment, and discloses an adjustable intelligent cooling water manufacturing filtering device for a continuous casting machine. The filtering device comprises an adjusting assembly; the adjusting assembly comprises a cam; and the lower part of the cam is movably connected with a lifting toothed plate. Through cooperation of a cam, a lifting toothed plate, a transmission gear, a toothed rod, a movable block and a hinged inclined rod, the relative positions of filter holes in a porous adjusting plate and filter holes in a filter plate are adjusted, the filter precision is improved, and therefore heat pulsation is eliminated. The device can reduce diamond deformation and corner cracks of the casting blank and improve the casting quality. The connecting block is driven to move downwards through the self weight of the filter element, and the filter element base is fixed through the matching of the short connecting rod, the mounting plate and the clamping plate; meanwhile, the whole filter element is fixed through cooperation of the upper right-angle movable plate, the lower right-angle movable plate, the diagonal draw bar and the pressing block, so that the installation process of the filter element is simple and convenient, the repair and maintenance time of the filter device is shortened, the downtime of production equipment is shorter, and then more economic benefits can be created.
