PROBLEM TO BE SOLVED: To easily execute exchange work in a short time at the time of detaching a retainer. SOLUTION: A fixed member 8 is rotated counterclockwise as shown by an arrow G of a figure (a) by leaving the fixed member from a fixed rod by turning two knobnuts. An air guide 6 is released by only rotating a corresponding air blow-off member 70 by using three rotary joints 74 as a fulcrum clockwise as shown by an arrow H of the figure (a). In such a way, the detaching of filter fabric and the retainer is easily executed since the air guide 6 is released from restriction and removed upwards (clean air side space S) as shown by an arrow J of the figure (a). Further the air blow-off member 70 may be rotated by using a rotary joint 76 as a fulcrum as shown by an arrow K of the figure (b). The rotating directions of the arrow H and the arrow K are orthogonally crossed. Then the retainer is mounted and the knobnut 87 is properly fastened in a reverse procedure to the above-mentioned procedure. |
