Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a liquid discharge device for promoting discharge of an internally filled liquid in a flexible container used for liquid transportation and the like.

[Prior Art] In recent years, in liquid transportation, instead of tank trucks and tank containers, a sealed bag made of rubber or soft plastic is mounted on a cargo container of a marine container or truck, and the liquid is filled in the sealed bag for transportation. Flexible containers are used a lot. FIG. 6 shows an example of use of this flexible container, in which two flexible containers 1 are placed on a loading platform 31 of a truck 30. A liquid is stored in each flexible container 1, and the flexible container 1 is bound by a rope 32 to be fixed on the loading platform 31. In such a flexible container 1, a pouring / discharging port is provided in the upper part of its main body, and a valve 3 is attached to this pouring / discharging port to open / close the pouring / discharging port. A hose 33 is connected to the valve 3 via a hose coupler.
Is connected to a truck-mounted pump 34 or an external pump (not shown), and by driving these pumps, liquid is injected into the flexible container 1 and liquid is discharged from the flexible container 1. The reason why the inlet / outlet port and the valve 3 are attached to the upper portion of the main body of the flexible container 1 is as follows. That is, since the pouring / discharging port and the valve 3 are made of metal or plastic and have a large weight and volume, when they come into contact with the cargo bed 31 or the floor of the container, the main body of the flexible container 1, the pouring / discharging port, and the valve 3 are connected. It is easy to damage itself. In order to remove the cause of this damage and reduce the load burden, the pouring outlet and the valve 3 are attached to the upper part of the main body of the flexible container 1. For the same reason, a flexible container in which the pouring outlet and the valve 3 are attached to the side surface of the main body is also used. In FIG. 6, reference numeral 6 is an air valve for opening the inside of the flexible container 1 to the atmosphere when the liquid is injected and discharged.

[Problems to be Solved by the Invention] In a flexible container in which a pouring outlet and a valve are attached to an upper portion or a side portion of a main body, a liquid discharging operation is hindered, and a liquid residual amount is increased. That is, the liquid is discharged from the flexible container by suction of the pump or by natural flow due to gravity, but when the amount of liquid in the main body of the flexible container becomes small, the upper part of the main body lowers and comes into close contact with the lower part of the main body. This is because the part is blocked and the flow of the liquid to the pouring / discharging port is blocked, and a large amount of liquid remains in the flexible container. When the remaining amount of the liquid is large, the liquid amount loss rate increases, and the quality of the newly injected liquid is adversely affected, and further, it hinders the folding work of the flexible container and the carrying work thereof, which is preferable. Absent.
For this reason, artificial means such as lifting or inclining the pouring / discharging portion is performed, but even in this case, not only sufficient discharging cannot be performed but also a great deal of labor is spent on the work.

The present invention has been made in view of such circumstances, and provides a liquid discharge device for a flexible container that facilitates liquid discharge and reduces the residual amount without using artificial means. Is intended.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a valve which is attached to a pouring / draining port provided at an upper portion or a side surface of a flexible container to open / close the pouring / draining port. A liquid outlet communicating with the passage, and a guide passage radially formed so as to communicate with the liquid outlet, and a guide member attached to an end of the flexible container of the valve. It has a feature.

[Operation] In the above configuration, when the amount of the liquid is reduced by discharging the liquid and the upper part of the main body of the flexible container is lowered, the guide member comes into contact with the lower part of the main body, and the close contact between the main bodies is prevented. In this state, the liquid is introduced into the valve from the guide passage of the guide member through the liquid port, so that the discharge of the liquid is promoted.

[Embodiment] FIGS. 1 and 2 show a flexible container 1 to which the present invention is applied, in which a pouring port 4 is provided at a predetermined portion of an upper portion of a main body 7 formed in a bag shape from rubber, soft plastic or the like.
Is provided. A valve 3 is connected to an upper portion of the pouring / discharging port 4, and a hose coupler 2 is mounted on the valve 3. Further, a guide member 5 is attached to the lower portion of the valve 3. Reference numeral 6 is an air valve attached to the central portion of the upper portion of the main body 7.

FIG. 3 shows the details of the pouring / discharging port 4. A part of the upper portion of the main body 7 is opened, and the upper flange plate 4a and the lower flange plate 4b are attached so as to sandwich the peripheral portion of the opening 7a, whereby the pouring / discharging port 4 is formed. A liquid passage 8 is formed in the center of the pouring / discharging port 4, and the valve 3 is attached to the upper portion of the pouring / discharging port 4 so that the passage 3a communicates with the passage 8 of the pouring / discharging port 4. The valve 3 opens and closes the passage 3a by rotating the handle arm 9 forward and backward, and the opening and closing of the pouring outlet 4 is performed by this opening and closing. The hose coupler 2 attached to the upper portion of the valve 3 is fitted with the ends of the hose when the liquid is injected and discharged. The valve 3 and the hose coupler 2 are integrally attached by screwing a bolt 10 to the lower flange plate 4b. The guide member 5 has a liquid port 11 communicating with the passage 3a of the valve 3, and is attached to the end of the valve 3 on the main body 7 side.
In the illustrated example, the valve 3 is attached to the flange plate 4b at the lower part of the pouring / discharging port 4, and the guide member 5 is positioned on the inner end of the valve 3 by being bonded to the lower surface of the lower flange plate 4b. It is installed so that

FIG. 4 shows this guide member 5, the outer shape of which is formed in a ring shape, and the central portion of which is a liquid port 11. Further, on the lower surface of the guide member 5, a groove-shaped guide path 12 communicating with the liquid port 11 is formed.
Are radially formed. The guide member 5 is attached to the inner end of the main body of the valve 3 to guide the liquid to the valve 3 during discharging. In this case, the guide member 5 is formed of metal, plastic, or the like into the shape shown in the figure, but is formed of soft plastic from the viewpoint of alleviating the impact at the time of contact with the main body and preventing damage to the main body. preferable.

In the above configuration, connect the hose to the hose coupler 2,
By opening the valve 3 and performing suction, the inside of the main body 7 is discharged. When the amount of liquid in the main body 7 decreases due to this discharge, the upper portion of the main body 7 lowers and approaches the lower portion.
At this time, the guide member 5 attached to the lower end of the valve 3
Contacts the lower part of the main body 7 to prevent mutual contact between the upper and lower parts of the main body 7 in the peripheral portion of this portion. Therefore, the pouring / discharging port 4 portion is not blocked, and the liquid can be smoothly discharged. Even when the liquid amount further decreases, the liquid passes through the guide path 12 of the guide member 5 and reaches the liquid port 11, so that the liquid is continuously discharged from the valve 3. Therefore, the discharge of the liquid is promoted, and the residual amount in the main body 7 becomes extremely small. Hereinafter, the operation of the guide member 5 will be described based on specific numerical values. A guide that has a width of 6 m, a width of 2.4 m, and a height of 1 m, and has a pouring / discharging port 4 with a diameter of 8 cm attached to the upper part of the main body 7 with a capacity of 14 kl, and a liquid port 11 with the same diameter on the lower surface of the pouring / discharging port 4. When the member 5 was attached and the liquid was discharged, the remaining amount of the liquid was 10 l or less. In this case, the guide path 12 of the guide member 5 was formed in a groove shape having a width of 1 cm and a depth of 1.2 cm, and 16 groove-like guide paths formed radially were used. On the other hand, when the liquid is discharged under the same conditions except that the guide member 5 is not attached, the remaining amount is 45
The discharge promoting effect of the guide member 5 is remarkably exhibited.

FIG. 5 shows another embodiment of the guide member.
Circular through holes (13) are radially formed in the. The through hole 13 communicates with the central liquid port 11 so that the liquid is
It serves as a guide path for guiding to 11, and even if the guide path is formed in this way, discharge of liquid can be promoted in the same manner as in the above-mentioned embodiment.

[Advantages of the Invention] As described above, according to the present invention, the guide member is attached to the end of the valve in the flexible container to accelerate the discharge of the liquid. This has the effect of eliminating various inconveniences.
