Abstract

332,601. Bramwell, I. L., Holmes, C. W. H., and Birtley Iron Co., Ltd. Jan. 23, 1929. Filtering. - Filter bags are cleaned by reversing the direction of the air passing through them, removing the dust from the inside of the bag. The fan a draws the dust laden air through the intake b and the filters e and f containing the filter bags g and h. Valves k and m are arranged at the filter outlets, and valve& j and connect the filters to atmosphere. To clean the filter bags g the valve k is closed and valve j is opened so that air passes from the atmosphere through the bags, removing the dust, and passes through the filter f. A similar operation is carried out to clean the filter bags h. A modification has the two valves k and j cantained in a single fitting. The valves are operated by' hand. Specifications 7550/12, 8752/12, 237,232, 273,563 and 281,994 are referred to.
