[0002] The bearing seat is a workpiece used to install the bearing. The bearing seat casting is often cast using molten metal during production and processing. For the molten metal containing aluminum or aluminum alloy, when inclusions are contained in them, it will become the cause of defects in the casting during casting, or it will become the starting point of cracks when the casting is rolled. Therefore, the molten metal is filtered to remove inclusions.

[0003] The inventors have found in their daily work that most filtration devices only filter through a single filter during use. During the production process, debris is easily attached to the filter and thus easily remains inside the equipment, causing pollution to the equipment and affecting subsequent production of the equipment. Improvements are needed in this regard. Summary of the invention
