Patent ID: 7820113

Claim:
A device for simultaneously collecting served filter paper and filtered water through the filter paper for analyzing, comprising: plurality of funnel-shaped filtering units, comprising: an influx container opened at its top and bottom to allow sampled water to pass through, a seat adapted to be removable on a lower end of the influx container in such a way that said filter paper is interposed between the influx container and the seat, with a feeding pipe vertically and downwardly extending from a lower portion of the seat, and a plug provided with a through hole in which said feeding pipe is fitted, a supporting unit, comprising: at least one supporting plate provided with a plurality of support through holes, plurality of plug support blocks of the same number as that of said support through holes, which comprises a large-diameter hollow part at an upper portion thereof and a small-diameter hollow part at a lower portion thereof, wherein said large-diameter hollow part closely receives the plug of the funnel-shaped filtering unit, and said small-diameter hollow part is inserted into said support through hole to be sealed, a vacuum release valve provided at a position of an outer surface of said plug support block so as to release an internal vacuum state of the plug support block, at least one sealing means provided on a lower surface of the supporting plate at a position around said support through holes, and at least one first attaching means provided on the lower surface of the supporting plate at a position outside said sealing means; a drain tank defining a space therein and comprising: first through holes of the same number as that of said support through holes, which is provided at a top surface of the drain tank, a second through hole provided at a predetermined position of the top surface of the drain tank, a discharging through hole formed at a predetermined position of the lower side of the drain tank, and a shut-off cock placed at said discharging through hole; a mounting means provided with supporting rods to support said supporting unit over said drain tank in such a way that said supporting unit is spaced apart from said drain tank by a predetermined distance; at least one filtered water storage unit, comprising: at least one main body of the same number as that of the support through holes, which is opened at its top and defines a space therein to hold a filtered water container for collecting filtered water, wherein said main body comprises a flange extending around an upper portion of the main body, and provided with a second attaching means to be attached to the first attaching means of said supporting unit and a drain through hole formed at a center of a bottom of the main body, and a drain tube whose one end is connected to the drain through hole of the filtered water storage unit and the other end is connected to the tube connecting through hole of the drain tank; and a vacuum pump connected the second through hole via a pump tube.
