Ultrafine ground calcium carbonate slurry grading filter

Abstract

This utility model relates to the field of filter technology and discloses a graded filter for ultrafine ground heavy calcium carbonate slurry, including a first filter element, a second filter element, and a third filter element, with the second filter element located inside the third filter element. Filter holes are formed on the first, second, and third filter elements, and the pore size of the filter holes on the first, second, and third filter elements gradually decreases. A second connector is fixedly connected to the top of the third filter element. This utility model, by setting the first connector, the second connector, the first connecting hole, and the second connecting hole, allows the first, second, and third filter elements to be detachably connected. Simply rotating the first, second, and third filter elements allows them to be separated and cleaned, reducing the difficulty of cleaning the first, second, and third filter elements and shortening the cleaning time of the device.
