Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a liquid tank that stores a plurality of types of liquids, such as different types of oil, by dividing the inside of the tank with a diaphragm.

Some petroleum tanks have a flexible partition that reversibly partitions or divides the inside of the tank so that a plurality of oil types can be stored together. For example, by combining kerosene with other oil types, seasonal fluctuations in the amount of kerosene stored can be absorbed and tank utilization efficiency can be increased.

A tank structure with such a diaphragm is also effective for lubricating oils that are characterized by a wide variety of products in small quantities.By using a diaphragm, one tank can be used for multiple purposes, and it absorbs fluctuations in the amount of oil stored, making tank utilization easier. It is possible to improve efficiency and increase the degree of freedom in production and operation.

However, when it comes to lubricating oil, piping as shown in Figure 1 (
2) may be provided in the tank (1) to effectively disperse and mix additives or base oils.

When such piping (2) is installed inside the tank (1) and a diaphragm (3) is provided as shown in Figure 2, the diaphragm (3)
This obstructs the inflow of liquid from the pipe (2) and proper dispersion, and the pipe (2) also becomes an obstacle for the diaphragm (6), resulting in damage to the pipe (2) and the diaphragm (3). .

In view of the above, the present invention has been developed to overcome these drawbacks. That is, in the present invention, the piping and the diaphragm in the tank are separated by a porous plate-like body, and the inflow and dispersion of the liquid from the piping are performed well, and the porous plate-like body: a.
To provide a liquid tank in which piping and diaphragms are not damaged due to shielding effects.

The present invention will be described below with reference to two embodiments shown in FIGS. 6 and 4. It should be noted that the same reference numerals in each figure indicate in-phase roaring parts.

First, in the one shown in Fig. 6, the two-liquid pipes (2), (2) are gathered on one side of the tank (1) and surrounded by a perforated plate-like body (4) and a side wall (5) facing it. That is, a vertical piping chamber (6) is formed, and this chamber (6) is divided into each divided chamber (8).
, (8) is divided by the partition plate (7) K so that the pipes (2), (2) can be installed therein, and the attachment part (9) between the perforated plate-like body (4) and the partition plate (7) is formed. A diaphragm (6) as shown in Figure (C1) is attached to the part (5') of the tank side wall on the opposite side, and this diaphragm (3) has holes (3a) corresponding to the porous plate (4). ).The perforated plate-like member (4) may be any suitable member such as a perforated iron plate or a wire mesh-shaped member.

With the above configuration, the shielding effect of the porous plate (4) prevents contact between the diaphragm (3) and the pipe (2), so the inflow of liquid from the pipe (2) is inhibited by the diaphragm (3). Also, the porous plate (4) and tank side wall (
Since a space surrounded by (5) and
), the liquid dispersion is good because the outlet is not blocked, and the diaphragm (3) does not get caught on the pipe (2), so there is no damage to the pipe (2) or the diaphragm (3). It is.

Next, in the case shown in Fig. 4, instead of the adjacent pipes (2), (2) in the previous example (Fig. 6), the two-liquid pipes (2), (2) are placed on opposite sides of the tank. The porous plates (4'), (4') and the side wall (5) are provided at opposing positions to the side wall (5).
5), that is, the piping chambers (6') and (6') formed by the porous plate-like body (A'
2'), (2') are installed, and the part (5") of the side wall at a position perpendicular to the line connecting the piping (2'), (2'), (5") is installed. Diaphragm (3) shown in figure (bl)
') is attached, and its operation and effect are the same as the previous example (Fig. 6), so the description thereof will be omitted.

As described above, in the liquid tank of the present invention, the piping installed in the height direction inside the tank is surrounded by the porous plate-like body and the tank side wall, that is, the piping is installed in the piping chamber formed by the porous plate-like body and the tank side wall. A diaphragm with a defect corresponding to the shape of the piping chamber is placed inside the tank, so that the diaphragm does not come into contact with the piping due to the perforated plate-like effect, so the inflow of liquid from the piping is prevented by the diaphragm. Force S to be inhibited by
In addition, since the space surrounded by the porous plate and the side wall of the tank is removed, air can be blown out even in piping with an air outlet.]] Force (no blockage, good dispersion of liquid, and the diaphragm does not get caught in the piping) Therefore, there is no damage to piping or diaphragms.
