Abstract

PURPOSE: To prevent radiation of heat from the liquid tank and enhance the descaling functin by a method wherein stationary float units are provided on either side of an elevating-type float unit to cover some part of the liquid surface.
CONSTITUTION: In the liquid tank 1 wherein the liquid surface is covered with plastic floating units consisting of a plurality of flat hollow elements coupled in parallel, the elevating-type float unit 5 having the same width as the objective metal plate 7 and placed in the central area is lifted by a winch or a lifting-up means 3. In addition, the floating units 6 formed by cutting the parts contacted with the walls of the tank 1, i.e. the parts on either side of the unit 5, are fixed so as to normally cover the liquid surface. Accordingly, even when the unit 5 is hoisted by the winch or the lifting-up means 3, the stationary floating units 6 always cover the liquid surface.
