The filter disk 6 with a corresponding size of through groove can also be replaced according to the diameter of the filter element 7 and engaged on the mounting block 5 to fix the position of the filter element 7 so that it is evenly spaced and distributed to more comprehensively adsorb and filter the iron powder in the medium.
