Abstract

PURPOSE: To peel filter cake such as red mud, etc. on the surfaces of filter leaves by spouting washing water onto the backing plate provided at the top of the filter leaves at the time of opening the split shells and also spouting the same between the filter leaves within a pair of the split sheels which are closed or opened in proximity or spacially.
CONSTITUTION: The other split sheel 1b is movable approached to or spaced from the split sheel 1a which is normally held stationary. Since a backing plate 11 exists at the top of a filter leaf 4, the filter cake 14 does not deposit on the backing plate 11 portions and deposits on both surfaces of the filter leaf 4. When washing water is spouted from a nozzle 12 while the split shell 1b is being speed from the split shell 1a, then washing water flows gradually into the filter cake 14 and filter leaf 4 (surfaces where the filter cake 14 deposits). When the weight of the filter cake 14 exceeds the resistance force by the friction between the filter cake 14 and filter leaf 4, the filter cake 14 drops by gravity.
