PURPOSE:To remarkably enhance the housing capacity of a bag filter for a dust collector housing by nearly making the cross-sectional shape of a retainer for the bag filter to an ellipse or an oval shape. CONSTITUTION:A ring for fitting the inlet edge part of the retainer for a bag filter is nearly made to an oval shape by bending and working one piece of bar. A guide cylinder 2 is fixed to the ring 1 for fitting. A joining rod 3 is made to a long-sized bar shape wherein the upper end part is fixed to the guide cylinder 2 and about eight pieces thereof are provided. Caps are fitted and fixed to the lower ends of the joining rods 3 and the whole body of the retainer R is fixed to a grid frame body having a nearly oval shape. Thereby the cross-sectional area of the oval-shaped retainer can be made small in comparison with a cylinder-shaped retainer, thereby the number to be housed in a dust collector housing can be increased. |
