Title: Spray cleaners for paper-making machine screens and filters - having two counter reciprocating sections driven by pressurised water
Inventor: HAMMELMANN PAUL
IPC: D21F1/32
Filed: 1979-12-08
Abstract: Cleaning sprays for papermaking machines with widths of 10 m or more comprises two counter-reciprocating spray tubes mounted on a tubular carrier which extends across the full machine width. The spray tubes are closed at each end by end-caps, of which the inner caps have a greater internal surface area than that of the outer caps, whereby the water pressure produces a net closing-force driving the tubes together. The two sections are connected by at least one hydraulic cylinder, whose working surface area is greater than the excess area of the inner end-caps over the outer caps, giving a net outward force on the two tubes. A self-acting slide valve reverses the motions of the tubes at the end of each stroke. This construction gives a counter-balancing of the moving parts which ensures reliable operation for long periods.
