  The present invention relates to a metal container.

  Conventionally, metal containers are known as liquid storage tanks used for industrial applications.

  By the way, depending on the shape of the container, a stationary fluid region is generated inside the container. A stationary fluid region may degrade the quality of the liquid stored in the container. On the other hand, it is possible to eliminate the static fluid region by arranging a stirring mechanism inside the container, but the structure of the container becomes complicated.

  An object of the present invention is to provide a metal container capable of stirring a stored liquid without using a drive mechanism.

  The first invention is a metal container whose outer shape is a substantially rectangular parallelepiped, and has a bottom plate portion, a side wall portion and a ceiling portion, and a drain outlet is formed in the vicinity of the lowest point in the bottom plate portion, The bottom plate portion is configured to have a shape that functions as a first water flow generating means that generates a water flow that is directed obliquely downward with respect to the liquid stored therein, and the side wall portion is formed in the vertical direction of the metal container with respect to the liquid. It is a metal container which is comprised in the shape which functions as a 2nd water flow generation | occurrence | production means which produces the water flow which crosses perpendicularly and goes to the center direction of the said metal container.

  According to the configuration of the first invention, the inner shape of the metal container functions as the first water flow generating means and the second water flow generating means. When the liquid stored inside is discharged from the drain outlet, water flows in different directions are generated by these water flow generating means, and the liquid stored in the metal container is agitated. That is, the stored liquid can be stirred without using a drive mechanism.

  According to a second invention, in the configuration of the first invention, an inner surface of the bottom plate portion is formed in a curved shape inclined toward a lowest point in the bottom plate portion, and an inner surface of the side wall portion is formed from the ceiling portion. It is a metal container having a plurality of curved protrusions extending toward the bottom plate.

  A fourth aspect of the invention is the ratio A1 of the width (B) of the inner surface of the metal container to the radius of curvature (R1) of the curved surface of the inner surface of the bottom plate portion in any one of the first to third aspects of the invention. (B / R1) is a metal container specified in the range of 0.5 to 0.7.

  According to a fifth aspect of the present invention, in any one of the first to fourth aspects, the ratio A2 (R2 / A1) of the radius of curvature R2 of the curved protrusion to the ratio A1 is defined as 16 or more and 66 or less. It is a metal container.

  Hereinafter, modes for carrying out the present invention (hereinafter referred to as “embodiments”) will be described. In the following description, the same reference numerals are given to the same components, and the description thereof is omitted or simplified. Note that description of configurations that can be appropriately implemented by those skilled in the art will be omitted, and only the basic configuration of the present invention will be described.

<First embodiment>
FIG. 1 is a schematic view showing a metal container 1 (hereinafter referred to as “container 1”) according to an embodiment of the present invention. FIG. 2 is a schematic view showing the main part of the container. The container 1 is a metal container that stores a liquid therein, and its external shape is formed in a substantially rectangular parallelepiped. The liquid is, for example, drinking water. A water intake 4 is formed in the front surface 2 so that the liquid inside can be discharged. A relatively clear liquid is discharged from the water intake 4. The bottom plate part 6 constitutes the bottom part of the internal shape of the container 1. The inner surface of the bottom plate portion 6 is formed in a curved shape that is inclined toward the lowest position in the bottom plate portion 6, and a drain port 8 a is formed at the lowest position of the bottom plate 6, that is, at the bottom portion. The liquid discharged from the drain port 8a passes through a drain path 8b disposed below the bottom plate portion 6, and is discharged from the drain outlet 8c to the outside of the container 1. The drain port 8a can be opened and closed by a valve (not shown). When there is a precipitate or the like in the liquid near the bottom 6, a relatively turbid liquid is discharged from the drain outlet 8 c.

  The inner surface 10 of the side wall of the container 1 has a plurality of curved protrusions 10a (see FIG. 2) extending from the ceiling 12 toward the bottom plate 6.

  As shown in FIG. 3, the curvature radius R1 of the inner surface of the bottom plate portion 6 is formed larger than the curvature radius R2 of the curved protrusion 10a of the inner surface 10 of the side wall portion. A ratio A1 (B / R1) of the width B of the inner surface of the container 1 to the radius of curvature R1 of the inner surface of the bottom plate portion 6 is defined as 0.5 or more and 0.7 or less. In this embodiment, the ratio A1 is 0.6. The ratio A2 (R2 / A1) of the radius of curvature R2 of the curved protrusion 10a with respect to the ratio A1 is defined as 16 or more and 66 or less, and is 30 in the present embodiment.

  When the drainage port 8a is opened in a state where the liquid is stored in the container 1 because the inner surface of the container 1, that is, the shape of the portion storing the liquid is configured as described above, as shown in FIG. The curved surface shape of the bottom plate portion 6 causes the water flows F1 and F2 to go obliquely downward, and the curved surface protruding portion 10a (see FIG. 2) of the inner surface 10 of the wall surface portion is substantially orthogonal to the vertical direction of the container 1, and Then, the water flows F3 and F4 toward the substantially central direction of the container 1 are generated. That is, the curved surface shape of the bottom plate portion 6 functions as the first water flow generating means, and the curved protrusion 10a functions as the second water flow generating means. Thereby, the liquid stored in the container 1 is stirred.

  When the water intake 4 is opened, as shown in FIG. 4, water flows F3 and F4 are mainly generated by the curved protrusions 10a (see FIG. 2). For this reason, the liquid stored in the container 1 is in a state of being appropriately stirred, and is discharged from the water intake port 4 while hardly intersecting with the liquid below the water intake port 4. Depending on the type of liquid stored in the container 1, substances or solids that cause turbidity may precipitate in the vicinity of the bottom plate portion 6. From the water intake 4, substances that cause such turbidity or A liquid containing almost no solid matter can be discharged. On the other hand, when the drainage port 8a is opened, as shown in FIG. 5, in addition to the water flows F3 and F4 due to the curved protruding portion 10a (see FIG. 2), the water flows F1 and F2 due to the curved shape of the bottom plate portion 6 are generated. Arise. That is, when the drainage port 8a is opened, water flows in different directions are generated, so that the stationary fluid region can be more strongly reduced, and substances and solids that cause turbidity can be stirred into the liquid and discharged. can do.

<Second Embodiment>
Next, a second embodiment will be described. The description of the configuration common to the first embodiment is omitted.

  As shown in FIG. 6, in the curved protrusion 10a of the inner surface 10 of the side wall portion of the second embodiment, the curvature radius R3 of the base of the protrusion is formed larger than the curvature radius R4 of the tip. When the curvature radius R3 of the base portion is smaller than the curvature radius R4 of the tip portion, the inventor of the present invention does not generate a curvilinear water flow toward the front surface 2 (arrow X direction) and toward the center. As a result, the inventors have come up with a technical idea that the radius of curvature R3 of the base of the protruding portion is larger than the radius of curvature R4 of the tip.

  The present invention is not limited to the first embodiment or the second embodiment described above, but includes modifications and improvements as long as the object of the present invention can be achieved.
