Abstract
A filter is disclosed for removing loose particles carried in a liquid stream such as loose paper particles in a bottle washing machine. An outer tank surrounds an inner rotatable finely perforated drum mounted on an axial shaft running throughout the drum and tank. The shaft is hollow with spaced perforations and a back-wash liquid may be passed through the shaft to wash away small paper particles which may stick to the drum after an operation of the filter cycle. The contaminated liquid enters the outer tank near one end and passes along the length of the drum and through the perforated periphery thereof then out a clear discharge opening at a far end of the device.
