PURPOSE:To enhance the treating performance of a bar screen by using the bar screen of a bucket frame by combining bar screens of large mesh and those of small mesh being installed in a vertically and alternately varying manner. CONSTITUTION:A bucket frame 6 is combined with carrying chains 1 of left and right-handed two rows in such a way that no aperture is formed between the adjacent vertical ones to form an endless band rotary type screen 10. Bar screens 7 and 8 in which comb-shaped bars are arranged at a given interval are attached to the back side of the bucket frame 6. Jellyfish and small fish are partly passed through the screen 7 of the large bar interval but the others are partly scooped by the screen 8 of small bar interval. Abnormal situations such as rush of many jellyfish at one time to the net dust remover set on the downstream side can be exactly prevented. |
