Description

[Detailed description of the invention] For example, storage materials such as volatile oil that should be prevented from evaporation loss during storage, or CWM (Coal Water
A floating lid may be provided on the liquid level inside the sealed tank in a tank for storing a stored substance in which evaporation of some of the components such as water in the mixture should be prevented. Furthermore, it is necessary to prevent the generation of static electricity when receiving stored items,
For the purpose of first-in, first-out, it may be flowed down from near the upper end of the side wall along the inner circumferential surface of the side wall.

The present invention relates to an improvement of such a tank with a floating lid, in which a receiving tub is arranged along the inner peripheral surface of the upper end of the side wall of an upright tank with a roof, and slits are arranged in a row along the tank side wall of the receiving tub. A receiving pipe whose tip end opens into the inside of the receiving tub is installed in the upper part of the tank, and a receiving pipe is provided below the receiving tub over the entire outer periphery of the floating lid that floats on the liquid level stored in the tank. Located in
In addition, it relates to a tank with a floating lid that is characterized by having an upright guide whose upper edge is inclined toward the center of the tank, the purpose of which is to allow the liquid stored in the tank to be smoothly received under the floating lid. An object of the present invention is to provide an improved tank with a floating lid configured to prevent leakage onto the floating lid.

Since the tank with a floating lid according to the present invention is constructed as described above, the stored liquid received into the tank from the receiving pipe installed at the top of the tank flows along the inner peripheral surface of the upper end of the side wall of the tank. The liquid is received in a receiving tub, and flows down along the side wall of the tank through slits arranged along the inner periphery of the receiving tub. In this way, the received stored liquid flowing down along the side wall of the tank is guided by the outer circumferential surface of the guide, which is disposed around the outer circumference of the floating lid and whose upper edge is inclined from the center of the tank, and is always guided by the outer circumferential surface of the guide that extends around the outer circumference of the floating lid. It is guided downward and does not flow onto the floating lid. As described above, according to the present invention, the stored liquid received in the tank can be quietly introduced into the lower part of the floating lid.

Furthermore, according to the present invention, the floating lid and the guide provided on its outer periphery constitute a container that floats on the storage liquid surface where buoyancy is obtained, thereby eliminating the need for a buoyancy chamber that requires complicated construction and inspection. No need for installation, maintenance,
The present invention has many advantages, such as ease of inspection.

Hereinafter, illustrated embodiments of the present invention will be described.

Reference numeral 1 denotes an upright cylindrical tank erected on the ground a, with a discharge pipe 2 disposed near the bottom and a receiving pipe 3 opening near the upper end of the side wall. A receiving tub 5 in which slits 4 are lined up along the entire circumference or almost the entire circumference of the upper end of the side wall is provided, and the tip of the receiving tube 3 is opened inside the receiving tub 5. .

A floating lid 6 that floats on the level of the stored liquid is disposed inside the tank 1, and a guide 6a with an upper edge inclined toward the center of the tank is provided over the entire circumference of the floating lid 6. Therefore, since buoyancy is obtained by the space surrounded by the floating lid 6 and the guide 6a, there is no need to provide a separate buoyancy chamber in the floating lid 6.

When receiving the stored liquid, the stored liquid received into the tank from the receiving pipe 3 enters the receiving tub 5, flows along the inner peripheral surface of the side wall of the tank, and flows into the receiving tub 5.
The liquid flows along the side wall of the tank through the slits 4 arranged in rows along the side wall of the tank, and quietly enters the liquid stored in the tank, thereby preventing the generation of static electricity due to flow. be done.

Note that after the stored liquid received in the tank flows down, it is not guided to the upper side of the floating lid 6.
A guide 6a is provided at an appropriate height on the outer peripheral edge of the floating lid 6 facing the side wall of the tank, and is combined with the side wall to form an upwardly open flow path. It is constructed so that there is no problem even if there is eccentricity, and thus the receiving liquid is always connected to the floating lid 6.
guided below.

In this way, with the illustrated tank with a floating lid, the receiving liquid can be introduced quietly under the floating lid, and the floating lid and guide form a container that floats on the surface of the stored liquid, making it easier to manipulate. Since there is no need to provide a buoyancy chamber that is troublesome to inspect, inspection and maintenance become easier.
