Abstract

PURPOSE:To increase liquid-level area covered with float balls which are floated by a large number to cover liquid surface to prevent resolution of gas, vaporization of liquid or the like by specifying weight per volume with respect to a waterline. CONSTITUTION:A float ball 1 is substantially shaped in a ball and formed by jointing two members 2 and 3 in the vicinity of a diameter part, and a weight 4 having a prescribed weight is housed in the ball 1. Its specific gravity is specified corresponding to that of a liquid to which the balls are applied to. In addition, a waterline of the ball 1 is specified to come near a maximum cross sectional area position (if the float ball 1 is shaped in a ball, a diameter position) when the ball 1 is floated on the liquid to which the float ball 1 is applied. When the float balls 1 are applied to a boiler tin, for example, in which deaerated water is used as boiler water for preventing corrosion of the inside of the tin, they protect liquid surface of the deaerated water from air contact without fail, and at the same time, prevent resolution of air into the deaerated water.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a float ball, and more particularly, it is floated on a liquid in a container to cover the surface of the liquid to prevent re-dissolution of gas into liquid and evaporation of liquid. About the float ball

[0002]

2. Description of the Related Art In recent years, degassed water from which dissolved gas has been removed is beginning to be used in various industrial fields because it is effective in preventing corrosion of metallic materials and shortening food processing time.

If the above degassed water is left to stand, the air will dissolve again into the degassed water, impairing the above effects. In order to solve these problems, it may be sealed in a storage container under a vacuum, but this makes the storage container and its accessories bulky and too costly. Therefore, the floating body is floated so as to cover the surface of the liquid, and the contact between the liquid surface and the air is blocked to prevent the above-described gas dissolution and liquid evaporation.

As the above-mentioned floating body, a floating body in which cork grains and the like are coated with paraffin or a sponge-like foamed rubber is coated with acid-resistant and heat-resistant rubber (Jitsuko Sho-27-
9655), polyethylene beads, thin-walled hollow spherical floating bodies, and the like.

[0005]

By the way, the above polyethylene beads, cork particles coated with paraffin, etc., a floating body in which spongy foamed rubber is covered with acid-resistant and heat-resistant rubber, and a thin hollow spherical body In a floating body or the like, it is difficult to adjust the buoyancy of itself, and depending on the liquid to be applied, as shown in FIG. 8 and FIG. The area that the floating body can cover the liquid surface was small. In particular, in a thin hollow spherical floating body, since the buoyancy is large and the dewatering line is located below the floating body, the area covering the liquid surface is small and the suppression of gas dissolution and evaporation was insufficient.

Therefore, when these conventional floating bodies are used, the floating bodies are charged so as to form multiple layers on the liquid surface, the lower layer balls are sunk by the weight of the upper layer balls, and the maximum cross-sectional area of the lower layer balls is increased. It was necessary to make it a water-draining line, and it was necessary to throw in more balls than necessary for the liquid surface area.

Here, the weight of the weight (4) is determined according to the specific gravity of the liquid to be applied, and when the float ball (1) is floated on the liquid to be applied, the draft line of the float ball (1) is the maximum. It is set to be near the cross-sectional area position (in this embodiment, since the float ball is substantially spherical, the diameter position).

Such a float ball is, for example,
It is used as follows. For corrosion protection inside the boiler can,
When deaerated water is used as boiler water, the deaerated water is once stored in the water supply tank and then supplied. Therefore, a desired number of the float balls (1) according to the present invention are floated on the liquid surface of the boiler water in the water supply tank.

Then, in the float ball according to the present invention, as shown in FIGS. 2 and 3, since the respective water lines are set in the vicinity of the maximum sectional area position, the entire liquid surface can be efficiently covered, It is possible to reliably shut off the boiler water from the air and prevent the redissolved air.

By adjusting the weights of the members (2 ″ ′) and (3 ′ ″) themselves, the same operational effects are exhibited. That is, the weight per volume of the float ball (hereinafter referred to as apparent specific gravity) is set so that the vicinity of the maximum cross-sectional area part is the water line. In this embodiment, the float ball (1 ''') Since the shape of is substantially spherical, its apparent specific gravity should be set to 0.5 times the specific gravity of the liquid to be applied. This apparent specific gravity is set by the specific gravity of the material of the member (2 ''')(3''') or the member of the float ball (1 ''').

For the two members (2 ''') and (3'''), prepare materials of different weights, such as materials with different specific gravities or different thicknesses of the members themselves. The float balls having a desired apparent specific gravity are obtained by appropriately combining them. When the two members constituting the float ball are both manufactured from the same material, the apparent specific gravity may be adjusted by adjusting the wall thickness and the like.

Further, in the float ball according to the present invention, as shown in FIG. 7, the vicinity of the maximum cross-sectional area portion (because the outer diameter shape is spherical in this embodiment also becomes the diameter portion) is a boundary. , One side has a thin hollow part
