Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a liquid storage tank for storing liquid such as soy sauce.

(Prior Art) Conventionally, the inside of a liquid storage tank simply consists of a single space, and if all the liquid stored there is consumed, it is inconvenient for emergency use, etc. A situation where there is no storage capacity will occur until liquid is received.

As a countermeasure to this problem, as shown in Fig. 8, the tank 71
Measures have been taken such as attaching a gauge 72 to the side of the sensor, or attaching a flow meter 73 as shown in Fig. 9, but the former can cause damage to the gauge installation part, and the latter can damage the reliability of the meter itself. There were drawbacks in terms of gender, etc., and it was not necessarily satisfactory.

Furthermore, as shown in Japanese Utility Model Application Publication No. 55-47952, a tank has been proposed in which a discharge port and an auxiliary discharge port are provided at different heights, but the inside of the tank is still a single space. Therefore, not only is the height of the upper discharge port restricted, but
The installation location is limited to the side of the tank, which causes problems such as increasing the installation space.

(Purpose of the invention) The present invention was devised to solve the above-mentioned problems. It is an object of the present invention to provide a liquid storage tank which can be installed without being limited in its height or mounting location as in the past, and which can therefore reduce the installation space.

(Structure of the invention) In order to achieve the above object, the present invention includes a tank body having a liquid supply port, and a partition standing from the bottom of the tank body that defines a space and at least one spare space inside the tank body. a plate, a communication means provided at a predetermined height from the bottom surface of the tank body for communicating the space and the preliminary space, and a liquid discharge port provided at a lower side of the space and the preliminary space and provided with a valve, respectively. The valve is characterized in that both liquid discharge ports are communicated with each other on the downstream side of the valve to discharge the liquid to the outside.

(Example) Examples of the present invention will be described below with reference to the accompanying drawings.

First, the first embodiment will be described. FIG. 1 shows a cross-sectional front view of a liquid storage tank, and FIG. 2 shows a cross-sectional view taken along the line -- in FIG. 1.

The liquid storage tank 1 includes a sealed tank body 2, and a liquid supply port 4 and an exhaust port 5 are provided on the top surface 3 of the tank body 2.

A partition plate 7 is provided upright on the bottom surface 6 of the tank body 2 at a distance from the top surface 3, and the partition plate 7 is provided by joining the side edges to the tank bottom surface 6 and side surfaces 8.

This partition plate 7 allows the inside of the tank body 2 to be divided into a space 1.
0 and the preliminary space part 11.

A communication hole 12 is bored at a suitable height H from the bottom surface 6 of the partition plate 7 so as to communicate the space 10 and the preliminary space 11.

A conduit 1 is provided on the bottom surface 6 of the tank facing the space 10.
3, and an auxiliary outlet 16 is provided on the bottom surface 6 facing the preliminary space 11 via a conduit 15. Each conduit 13, 15 is connected to a valve 17, respectively.
It is connected to a pump 19 via 18.

The height H of the communication hole 12 from the bottom surface 6 and the distance L from the side surface 8 of the partition plate 7 are arbitrary.
The preliminary space 11 below the communication hole 12 may be determined depending on the amount of liquid to remain in the space.
The volume of the liquid becomes the residual amount of the liquid, and therefore the volume of the communication hole 12
The preliminary space section 11 at the lower level is the preliminary tank 11a.
to do.

Next, the operation will be explained. First, a liquid such as soy sauce is supplied into the tank body 2 from the liquid supply port 4. Next, the valve 17 connected to the space 10 is opened, the valve 18 connected to the preliminary space 11 is closed, the pump 19 is activated as necessary, and the discharge port 1 is opened.
4. Drain the liquid to an appropriate location via the conduit 13.

The liquid level in the tank body 2 gradually decreases according to the amount of discharge, and when it decreases below the communication hole 12, the liquid level in the space 10
Only the liquid inside is discharged, and the liquid in the preliminary space 11 below the communication hole 12 remains.

Then, when the liquid in the space 10 is exhausted, the valve 18 is opened and the liquid in the preliminary space 12 below the communication hole 12 is discharged.

Therefore, according to this embodiment, a certain amount of liquid can be reliably left in the tank body 2 by the preliminary space 11 below the communication hole 12, which is convenient in case of emergency use, etc. ，
18, a new order can be placed to prevent an out-of-stock situation.

In addition, since the lower part of the tank body 2 is divided into a space 10 and a preliminary space 11 through the partition plate 7, the discharge port 14 and the auxiliary discharge port 16 are provided without being restricted to a predetermined height as in the conventional case. Furthermore, the mounting location of the discharge port 14 and the auxiliary discharge port 16 is not limited to the side surface 8 of the tank body, but may also be provided on the bottom surface 6 of the tank as in the embodiment, thus reducing the installation space of the liquid storage tank 1. You can get used to it.

Further, the surface area of the liquid remaining in the preliminary space 11 below the communication hole 12 can be set small by appropriately determining the distance L between the partition plate 7 and the side surface 8 of the tank body. Therefore, when the liquid is soy sauce or the like, the amount of water that evaporates from the liquid surface and condenses on the side surface 8 and top surface 3 of the tank body 2 can be reduced, and the amount of water that falls and remains in the preliminary tank 11a can be reduced. It is possible to prevent situations such as local dilution of salt at the liquid surface of soy sauce, etc., resulting in contamination.

FIG. 3 shows a cross-sectional plan view of a modification of the first embodiment. In this case, the inside of the tank body 2 is defined by a partition plate 21 into a space 22 and two preliminary spaces 23, 23, and a communicating hole. 12, two preliminary tanks 23a,
23a is formed. In this case, the discharge ports are provided in each of the spaces 22, 23, and 23, respectively. In this modification, the amount of reserve can be adjusted in stages by opening and closing the discharge ports of the two reserve spaces 23, 23 with valves, respectively.

Next, a second embodiment will be described. FIG. 4 shows a partially sectional front view of the second embodiment, and FIG. 5 shows a sectional view taken along the line - in FIG.
The same symbols are given to the members.

A conduit 33 in which a valve 32 is interposed is arranged on the outside of the side surface 8 of the tank body of the liquid storage tank 31 in the second embodiment, and the conduit 33 is connected to the space 10 defined by the partition plate 7 and the preliminary space 11. Communicating with 33,
The conduit 33 is provided at a predetermined height H from the bottom surface 6 of the tank body.

In the third embodiment, in addition to the functions and effects of the first embodiment, a reserve tank 11b is further formed above the reserve tank 11a below the conduit 33 by closing the valve 32, and the reserve amount can be adjusted in stages. can be done. Incidentally, when the valve 32 is not provided in the conduit 33, the same functions and effects as in the first embodiment can be obtained.

FIG. 6 shows a side view of a modification of the third embodiment,
In this case, the conduit 33 with the valve 32 interposed
According to this modification, four preliminary tanks 11a, 11b, 11c,
11d is formed so that the reserve amount can be adjusted in stages.

In the first and second embodiments, the upper end of the partition plate 7 may be joined to the upper surface 3 of the tank body, and in this case, the partition plate 7 serves as a strong reinforcing material for the tank body 2. accomplish

Further, in the first and second embodiments, if the valves 17 and 18 are configured so that when one is open, the other is closed, the tank body 2 will not be emptied due to erroneous operation. The interlocking means may be such that the solenoid valves 17A and 18A are operated by a controller 51 as shown in FIG. 7, or may be mechanically interlocked by connecting the handles of the valves with a chain or the like. In addition, 17B and 18B in FIG. 7 are manual valves.

(Effect of the invention) As is clear from the above explanation, according to the invention,
It is possible to ensure that a certain amount of liquid remains, making it convenient for emergency use, etc., and the outlet can be installed without being limited to its height or installation location.
Therefore, the installation space can be reduced,
Furthermore, when the liquid is soy sauce or the like, excellent effects such as being able to suppress contamination due to falling condensed water as much as possible and increasing the rigidity of the tank are exhibited.
