Abstract: A filter tube for use in earth coated type filters includes a flexible permeable tubular sheet internally supported by a helical spring. The internal spring is connected between opposite ends of the filter tube to support the full length of the tube wall. One end of the tube is connected to an external spring and anchor plate. In a slack position, the tube end folds over an end collar connected to the spring. Extension of the anchor plate applies tension to stretch the spring and tube to a taut position during a cycling operation which oscillates the tube to dislodge accumulated material.

Abstract: A filter tube for use in earth coated type filters includes a flexible permeable tubular sheet internally supported by a helical spring which in one embodiment extends partially along the length of the filter tube. The unsupported free end or an intermediate portion is subjected to oscillation to dislodge contaminated coating material accumulated on the surfaces of the filter sheet. External means are provided at the free end of the filter to permit oscillation and to support a plurality of filter ends. In another embodiment, an internal spring is connected between opposite ends of the filter tube to support the full length of the tube wall. One end of the tube is connected to an external spring and anchor plate. In a slack position, the tube end folds over an end collar connected to the spring. Extension of the anchor plate applies tension to stretch the spring and tube to a taut position during a cycling operation which oscillates the tube to dislodge accumulated material.
