CYCLONE DEVICE

PROBLEM TO BE SOLVED: To provide a less noise generating cyclone device which not only draws a less sticking amount of powder than does a steel plate device but also can remove the stuck powder conveniently. SOLUTION: A cyclone body 1 is structured of an outer cylinder 5 having the conical part 11 of a discharge aperture 12 connected to the cylindrical part 9 of an inlet and a lid 7 having an inner cylinder 6 and is attached by a support 3 into which the outer cylinder 5 is fitted in a freely attachable and detachable manner. In the cyclone device of the described structure, the outer cylinder 5 is molded of rubber or a similar material to the rubber. Thus the clogging amount of powder due to the sticking or the solidification of the powder on the inner face of the cyclone body, is reduced, so that the function of the cyclone device 1 is maintained normally and in turn, the workability for operating a machine is enhanced. In addition, the elastodeformation of the outer cylinder can easily remove the powder even when it sticks to the outer cylinder and further, the device is lightweight and easy to handle almost without the generation of noise.
