Centrifugal filter casing
 A liquid filter comprising a casing having a feed pipe, at least a drain pipe and at least a flushing pipe respectively fastened at different level positions, at least a circular filter and at least a rotary wire brush device. Feeding liquid which is pumped through the feed pipe along the inner wall into the casing is induced by the drain pipe and stirred by the wire brush device to rotate inside the casing permitting the mid-stream of the rotating liquid to penetrate through the circular filter. The filter has a smooth, elastic, convex outer surface which prevents fibrous or other debris from attaching thereto, form mid-stream osmosis filtration effect under straining rotation fluid at constant flowing pressure. Filtered liquid is partly pumped into the casing to flush the smooth, elastic, convex outer surface of the circular filter form different straining fluid pressure on the straining media while the brushing wires of the revolving axle of the brush holder are carried to pat on the smooth, elastic, convex outer surface of the circular filter causing fibrous or other debris to be shaken away from the circular filter toward the low liquid pressure area at the bottom of the casing around the drain pipe for discharging out of the casing through the drain pipe so as to keep straining media clean during straining or after filtration and to obtain constant filtration effect.
