Abstract:
A horizontal pressure filter including a washing liquid recovery channel for receiving unused washing liquid from the washing liquid inlet channel and conducting said unused washing liquid to a washing liquid recovery outlet. A flow controller arranged to selectively open and close a flow connection between the washing liquid inlet channel and the washing liquid recovery channel, and respectively, between a compressed gas inlet and the washing liquid inlet channel, such that a gas flow from the compressed gas inlet to the washing liquid recovery channel via the washing liquid inlet channel may be induced, so as to flush unused washing liquid remaining in the washing liquid inlet channel to the washing liquid recovery outlet.

Claim (Index 19):
A horizontal pressure filter having multiple filter plates forming at least a filter chamber therebetween, said horizontal pressure filter comprising:\n a slurry feed channel for feeding slurry into a filter chamber so as to be filtered therein; a filtrate outlet channel for receiving filtrate from the filter chamber and conducting said filtrate to a filtrate outlet of the horizontal pressure filter, a washing liquid inlet channel for feeding washing liquid from a washing liquid inlet into a filter chamber so as to wash a filter cake formed in said filter chamber, a washing liquid discharge channel for receiving used washing liquid from the filter chamber and conducting said used washing liquid to a washing liquid discharge outlet of the horizontal pressure filter, a washing liquid recovery channel for receiving unused washing liquid from the washing liquid inlet channel and conducting said unused washing liquid to washing liquid recovery outlet, a compressed gas inlet, and a flow controller, wherein the filtrate outlet channel, washing liquid inlet channel and the washing liquid recovery channel may advantageously be arranged to at least partially share a common physical entity as their respective flow route, wherein said flow controller being arranged to selectively open or close a flow connection between the washing liquid inlet channel and the washing liquid recovery channel, and respectively, between the compressed gas inlet and the washing liquid inlet channel, such that a gas flow from the compressed gas inlet to the washing liquid recovery channel via the washing liquid inlet channel may be induced, so as to flush unused washing liquid remaining in the washing liquid inlet channel to the washing liquid recovery outlet.
