[Effect of device]

Since the present invention has the above-mentioned configuration, it solves the above-mentioned drawbacks of the prior art and has the following effects.

a. Since the cleaning of the element by blowing compressed air is carried out in a closed machine frame, dust removed from the element is not emitted to the outside, which is suitable for environmental hygiene.

b. Cleaning work is done automatically simply by setting the elements in the machine frame, so no human labor is required for the work,
It can contribute to the improvement of work efficiency in maintenance factories.

c. The element can be set simply by magnetically adsorbing the element to the element fixing member arranged in the machine frame, and its removal can be easily performed by operating the element removing metal fitting attached to the element fixing member. . The magnets are rod-shaped and have an appropriate length. Since a plurality of magnets are attached radially from the outer peripheral edge direction of the magnet attachment plate toward the center direction, the appropriate position is used to determine the diameter and height. The attachment / detachment operation of all different elements can be performed with one touch (same single operation). Further, since the element removing metal fitting is pivotally attached to the outer end of the magnet, it does not interfere with the element attaching / detaching operation. Therefore, the work efficiency of the attachment / detachment operation of the element with respect to the machine casing can be improved.

d. Since the element fixing member has both a function for attaching and fixing the element and a function for rotating the element, it is not necessary to separately provide members for performing both functions, and the entire structure of the device can be obtained. Can be simplified.

e. When the element is magnetically attracted to the element fixing member, centering operation is performed to match the center guide of the element fixing member with the center hole of the element upper part, so that the element is fixed to the element fixing member regardless of the size. It can be quickly, easily and surely set in the position, so that there is no risk of the element swinging during the rotational operation of the element or contact accident with the blowing nozzle or the like due to the eccentricity of the element. In addition, since the center guides only project from the element fixing member toward the element side, the element of the element regardless of whether the frame material at both ends of the tubular body of the element is ring-shaped or dish-shaped. Easy to put on.
