PURPOSE: A bag filter cage multi-stage assembly apparatus is provided to minimize the abrasion of a filter bag as wire parts at the upper and lower ends of the cage are connected relatively smoothly. CONSTITUTION: A bag filter cage multi-stage assembly apparatus comprises a ring(220), a lower cage(200), multiple arcs(120), multiple arc gap spreading agents, and an upper cage. The ring is welded at the inside of a wire of a support stand for the form-retaining of the lower cage and the connection with the upper cage. The arc gap spreading agents connect multiple arcs welded at the outside of the support stand wire of the cage connection part. The upper cage includes the support stand wire which is bent to make the arc part to which arcs are welded to the outside of the wire be on the inner side of stand wire. Installing and detaching of the cage multi-stage assembly apparatus is possible only by manipulating the arc gap spreading agents.
