An apparatus for cleansing objects by passage through a tank containing a detergent liquor, which is subjected to ultrasonic vibration is provided with sprayers for rinsing the articles emerging from the detergent liquor by liquid drawn from the detergent bath. In order to control the build up of solids in the detergent bath, the liquor supplied to the sprayers is filtered through a moving filter band, from which the accumulated solids are removed by spraying wash liquor onto the reverse surface of the filter band. The filter band is mounted on a frame, which is supported by a pivot at one end and incorporates a suction box into which filtered liquid is drawn through the filter band. The filter band rests upon a support roller or the like. The weight of the frame tensions the belt. When the frmae and band are lifted out, the band is loose on the frame and may be replace very simply. The band may be driven by the external support roller or through a drive roller in contact with the reverse face of the band. |
