Abstract
388,247. Filters. DURANT, H. T., The Lodge, Worth Park, Crawley, Sussex, and STUBBINGS, E. O., 9, Salisbury Road, Carshalton, Surrey. April 20, 1932, Nos. 11365 and 30860. [Class 46.] A filter cloth or other medium is mounted on a resilient support which yields when a difference of pressure is set up between its sides but is capable of elastic recovery when the pressure is released. Figs. 2 and 3 show a filter element comprising cloth or canvas 23, a layer of jute sacking 22, a cylinder 21 of porous rubber, another layer 20 of jute and an inner core built up of four segments 11 of wood, ebonite or iron spaced apart by wedges 14 and formed with circumferential and longitudinal channels on the outer surface. A suction pipe 4 passes through the centre of the element. In a modified form of element shown in Fig. 5, the rubber cylinder and one layer of jute are omitted and resiliency is secured by using strips 28 of rubber to separate the segments 11. Pneumatic cushions may be used in place of the rubber cylinder 21 or of the rubber strips 28. Fig. 1 shows thickening apparatus with elements 3 as described and a central rotary shaft 6 carrying an agitating paddle 5 and horizontal cutter blades 8, 9, which loosen the settled material and promote its discharge through an outlet 7. The cake is detached from a filter element by breaking the suction and causing liquid to percolate or ooze through the element in the reverse direction. This may be done without stopping the suction pump by connecting the suction side of the pump to a supply of liquid in excess of that which the pump can take. It is stated that filter cloth having a backing of perforated sheet rubber may be used for the elements and that one or more spiral or other springs may be arranged under the filter cloth so as to allow of deformation during filtering and elastic recovery when the filtering pressure is released.
