Description

[Detailed description of the invention] This invention relates to a device for transporting liquids such as surfactants, latex, flocculants, and water for domestic and agricultural use.

Transporting liquids using tank trucks, tank containers, etc. has been common practice for a long time, but in liquid transport methods that use vertical and rigid containers, single-load transportation of containers is eliminated. However, there are drawbacks such as increased costs for collection, and because the container itself is heavy, the loading capacity is small.

The first object of this invention is to provide a liquid transportation device that allows liquids to be safely transported by commonly used transportation means such as trucks, freight cars, and ships.

The second purpose of this invention is to provide a liquid transport device that can significantly reduce the cost of collecting empty containers and that can transport different types of products back and forth using the same vehicle.

The third purpose of this invention is to provide a liquid transport device that can greatly increase the liquid loading capacity and that can maintain perfect quality.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

As shown in the figure, the liquid transport device according to the invention comprises a protective sheet 1, a sealed flexible rental container 10 placed on the sheet 1, and a belt 20 for securing the container 10.

The flexible container 10 has a pipe 11 on a part of its outer periphery, and a supply/discharge valve 12 is attached to the pipe 11 .

Further, an air vent pipe 13 is connected to the center of the top wall of the container 10, and an exhaust valve 14 is attached to the end of the air vent pipe 13.

The flexible container 10 is expanded by the liquid that is pressurized and filled into the interior through the injection tube 11, and is transported in the expanded state.

At this time, the injection tube 11 is unstable because it is separated from the support surface, so it is supported by an elastic pillow body 30 such as a sponge, and the pillow body 30 is tightened by means such as a belt. is fixed to the supporting surface by.

The lashing belt 20 consists of a fixed side belt part 21 and a tightening side belt part 22, and a hook 23 is attached to one end of both belt parts 21 and 22.

Further, a tightening fitting 24 of the tightening side belt section 22 is attached to the other end of the fixed side belt section 21.

The apparatus shown in the embodiment has the above structure, and the liquid filled inside the flexible container is transported via a transport means.

Here, as the transportation means, trucks, railway vehicles, ships, aviation, etc. can be adopted, but here, the method will be explained using an example of transporting liquid using a truck.

As shown in FIG. 1, first, the protective sheet 1 is spread on the loading platform 40 of a truck, and the stretched flexible container 10 is placed thereon, and then both sides of the protective sheet 1 are folded back over the container 10.

A plurality of lashing belts 20 are arranged in parallel in the vertical and horizontal directions above the container 10.

In the state shown in FIG. 1, a liquid supply hose is connected to the injection/discharge tube 11, the supply/discharge valve 12 is opened, and the exhaust valve 14 is opened, so that the container 10 is removed from the hose.
When the liquid is pressurized inside the container 10 , the air inside the container 10 is forced out through the air vent pipe 13 .

By pressurizing and filling the liquid while removing air from the air vent pipe 13, the container 10 expands from its flat state and deforms into a water pillow shape.Furthermore, pressurized filling is continued to reduce the liquid pressure at the top of the container 3. When a positive pressure is applied, the top wall of the container 10 bends.

When the amount of liquid filled reaches the set amount, such as by measuring the liquid pressure at the top of the container 10, the supply/discharge valve 12 is closed, the hose is removed, and if necessary, a blind cap is placed on the end of the injection/discharge tube 11. Install.

After filling the liquid under pressure, the hook 2 at the end of the lashing belt 20
3 is hung on the mooring fittings 41 provided on the outer periphery of the loading platform 40, the lashing belt 20 is tightened by operating the fastening fittings 24, the liquid inside the container 10 is pressurized, and the apex pressure is set to the set pressure. Preparation for transportation is complete.

”The above set pressure is 0.0 gauge pressure.
The pressure is preferably in the range of 3 to 0.23 kg/Crn2, and if the pressure is within the range, the container 10 is solid and difficult to deform.
is obtained, and liquid-filled containers can be transported stably.

The peak pressure of the liquid can be measured by attaching a pressure gauge to the air vent tube 13, or by connecting a transparent tube 15 to the air vent tube 13 and standing it up as shown by the chain line in FIG. It is possible to adopt a method of measuring the height of the liquid that has risen inside the container.

When transporting liquid using the flexible container 10, it is necessary to uniformly pressurize the entire container 10 by tightening the lashing belt 20 to prevent the liquid from flowing during transport.

As shown in FIG. 1, the fastener 24 at the end of the lashing belt 20 is placed on one side of the cargo platform 40, and the fastener 24 of the adjacent lashing bell 20 is placed on the other side of the cargo platform 40. If placed on the side, the entire flexible container 10 can be uniformly pressurized by tightening the lashing belt 20.

The flexible container 10 needs to be a pressure-resistant flexible container that can maintain the peak pressure of the liquid.
For example, it is preferable to use synthetic fiber woven cloth treated with synthetic rubber.

Such a drawn fabric may be of a multi-type such as a 2-ply type as well as a 1-ply type.

Further, the shape of the child figure of the container 10 can be any shape such as a square, circle, or oval, but a rectangular planar shape has a large base area, good stability, and is also suitable for manufacturing. preferable.

As described above, according to this invention, the inside of a flexible container is filled with liquid, and the container is fixed and transported by tightening a plurality of lashing belts that are stretched over the container. Liquids can be transported safely by using ordinary trucks, railway vehicles, etc., without using special vehicles such as can be transported to.

In addition, after the liquid inside the container is drained, the empty container can be folded into a small volume, and its light weight makes it easy to store and return.It is also possible to transport different types of products back and forth in the same vehicle, and to collect them. Costs can be significantly reduced.

Furthermore, the weight of the container itself is lighter than that of a steel container, allowing for a significant increase in loading capacity.Furthermore, since it is a sealed type, there is no continuous contact with air from liquid injection to discharge. This can be effective in maintaining quality.
