Bag-type filter

摘要

A bag-type filter contains a filter sleeve, a device for fastening the filter sleeve, which contains a spring shock absorber, which has upper clamp and lower clamp, which interact through a spring and are installed with possibility of mutual longitudinal travel, an unit of tension, which is movably articulated with the upper clamp, and an unit of connection of the shock absorber with filter sleeve, which is movably articulated with the lower clamp. The spring shock absorber contains the upper supporting plate and lower supporting plate, the upper clamp and lower clamp are installed with possibility of mutual longitudinal travel in mutually perpendicular planes in diametrically opposite openings made respectively in the upper supporting plate and in the lower supporting plate. The ends of upper clamp are fastened in the lower supporting plate, the ends of lower clamp are fixed in the upper supporting plate, and the shock absorber spring is located between said supporting plates, the unit of connection of shock absorber with filter sleeve is made in the form of a beam with a loop element in the middle. The opposite sections of the wall of filter sleeve in its upper part are flattened, they are connected together and on them two loops are formed, which are symmetrically located relative to the longitudinal axis of filter sleeve. Both arms of beam are installed in the loops, and the loop element of beam is movably articulated with the lower clamp of spring shock absorber.
