FLOATING FILTER AND FLOATING WATER STORAGE DEVICE USING THE FILTER

摘要

PURPOSE: To filter water without using a great power by providing a floating vessel having an opening on the wall surface, furnishing a filter plate made of cristobalite at the opening and by filtering the water by utilizing the water level difference between the inside and outside of the wall of the vessel floating on the water surface. ;CONSTITUTION: A float 4 is fixed to a floating vessel 1 having an opening 3 projecting inward on the bottom face 2 and having a square section, and a filter plate 10 is fixed to a flange 5 provided at the opening 3 by a bolt 7 through a presser plate 6. The filter plate 10 is formed by compacting a mixture contg. about 97wt.% of cristobalite grains having 0.2-0.8mm size and about 3wt.% of epoxy resin so that the water resistance corresponding to the water level difference of ≤20cm is obtained. The vessel 1 is floated on a lake surface, etc., hence the lake water, etc., are filtered by the filter plate 10 due to the water level difference (head difference) between the water surface 11 and the filter plate 10 in the vessel 1, and the filtered water 12 is stored in the vessel 1 and then discharged by a pump properly.;COPYRIGHT: (C)1995,JPO
