Abstract
This is concerned with an air filter cleaning arrangement in which the filter element, meaning the pleated filter media and its frame, is functionally connected to a vibrator so that it is resiliently or vibrationally isolated from the surrounding structure. The major effective component of the vibratory motion applied to the filter media is across the width of the filter pleats. The invention is used primarily in an industrial sweeper. It can also be used in other machines or equipment which have air filter.
Claims24
In an air filter assembly, a support housing, a filter frame in the support housing, a filter medium in the filter frame formed with pleats having height, width, and length, said filter medium being joined to and supported by said filter frame, a resilient mounting between the filter frame and the support housing so that the filter frame is resiliently isolated from the support housing at least in the direction of the width of the filter pleats, and vibrating means in continuous contact with said filter frame for vibrating said filter medium and filter frame to dislodge dirt and dust from the medium with the major effective component of the vibrations being across the width of the filter pleats.
In an air filter assembly for use in an industrial sweeper or the like, a mobile sweeper, a filter support on the sweeper, a filter frame, an isolation mounting for said filter frame in said support, filter media formed with pleats having a height, width, and length joined to and supported by said frame, said filter media having an air input and an air outlet, and vibration means in the sweeper in continuous engagement with the filter frame for vibrating said filter media and frame, with the major effective component of the vibration being across the width of the filter media pleats.
In an air filter assembly, a generally flat filter panel with pleated filter media therein, the pleats having a width generally along an X axis, a length generally along a Y axis and a height generally along a Z axis, a support for the panel, means for mounting the filter panel so that it is relatively free for movement along the X axis, and means in continuous engagement with the filter panel for vibrating the filter panel along the X axis so that the individual pleats will be flexed in the direction of their width to dislodge collected material.
