VACUUM FILTRATION APPARATUS AND VACUUM FILTRATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a vacuum filtration apparatus that is capable of supplying a uniform slurry on a filter cloth in a filtration part. SOLUTION: The vacuum filtration apparatus 10 conducts filtration by vacuum sucking slurry S supplied on the filter cloth 11 by a vacuum tray 16 by means of the filter cloth 11. The apparatus itself is provided with a supplying device 20 to supply the slurry S on the filter cloth 11. The supply device 20 is provided with a feed pipe having an opening part 21a to discharge the slurry S and a dispersion plate 22 arranged between the feed pipe and the filter cloth 11. The slurry supplied face 22a opposing to the feed pipe opening part 21a of the dispersion plate 22 is extended in an inclined state from the opening part 21a side onto the filter cloth 11. The opening part 21a can be swung toward the direction crossed with the inclination direction of the slurry supplied face 22a in the plane view of the slurry supplied face 22a.
