Abstract

253,148. Thune, S. June 6, 1925, [Convention date]. Rotary strainers; non rotary straining machines with pulsating elements.-Pulsations produced in a rotating-drum straining machine are communicated to a second straining machine. Paper pulp or other fibrous material passes from a supply channel A to a closed container surrounding a rotary drum M, which is provided with outwardly-projecting blades O. Pulsations are caused which promote the passage of the finer fibres through the drum for discharge through a central outlet U. The coarser fibres pass into an outlet chamber E and thence over a dam I and a flat strainer G. The pulsations of the first strainer are communicated by the chamber E and a diaphragm F to the chamber N below the strainer G. The fine fibres still present in the material passing over the strainer G are drawn through the strainer and may be conveyed by a trough L back to the channel A or to the outflow for the fibres from the interior of the drum. A plunger may be used for transmitting the pulsations in the chamber E to the chamber N. A cylindrical strainer may replace the flat strainer G.
