It is designed to rotate in numbers. Further, in the rotator 5, filter hole rows 8, 8, 8, in which a large number of filter holes 7, 7... are arranged in a row on the same radius, are formed at the lower end, middle portion, and upper end, and each of the filter holes 7, 7, . Receptacle rings 9, 9, 9 are attached to the outer circumferential surface of the rotator 5, facing the filter hole rows 8, 8, 8, respectively. The upper end 10 of each receiving ring 9 is fixed to the outer circumferential surface of the rotator 5 in a state that closes the gap with the rotator 5, and the lower edge thereof is open between the rotator 5 and the inner side. A protruding edge 11 is formed toward.
