Description

Flexi bucket for liquid cargo tank

The present invention is a flexi bucket for a liquefied cargo tank, which includes a hollow inside, and a plurality of plates made of plastic resin surround the flexi tank to minimize or prevent leaking of the leaked liquefied cargo to the container side and to the outside. It is about the flexi bucket for dragons.

A Flexi Tank is an equipment for transporting liquid cargo. The inner shell of the Flexitank is made of multiple layers of polyethylene (PE, with multiple layers of polyethylene (PE: PolyEthylene), and the outer shell of the Flexitank is made of polypropylene (PP: Poly Propylene), making it flexible and easy to store and use. There are advantages.

The Flexitank can be mounted inside the container to safely transport liquid cargo. A valve is installed on one side of the flexi tank so that liquid cargo can be loaded and unloaded into the flex tank on one side, and can be stored and maintained.

However, such a flexi tank may be torn or punctured by an external impact acting during the process of transportation or the operation of a ship. As such, when the Flexitank is damaged by an external impact, even with small scratches, the liquid cargo inside the Flexitank leaks and contaminates the container, and furthermore, there is a problem of contaminating the vessel or warehouse storing the container.

As such, when liquid cargo is leaked from the Flexitank, the liquid cargo is immediately removed from the Flexitank and placed in a new Flexitank and container. should contain And since a lot of work has to be done to remove the leaked liquefied cargo, it takes a lot of money and time, as well as environmental pollution.

In preparation for such leakage of the Flexitank, there is a method of installing corrugated cardboard made of paper between the Flexitank and the inner wall of the container. can't prevent them In addition, in the case of corrugated cardboard made of paper, there is a problem in that it cannot be prevented from being damaged due to a protruding structure or a sharp object disposed on the inner wall of the container or the floor of the transport environment.

Republic of Korea Patent Registration No. 10-2131997 (2020.07.02. Announcement)

FIG. 4 is a view showing a flexi bucket 10 and a flexi tank ( 3 in FIG. 2 ) disposed inside the container 1 .

Referring to FIG. 4 , when the Flexitank ( 3 in FIG. 2 ) is accommodated in the Flexitank 10 , the Flexitank 10 wraps the Flexitank ( 3 in FIG. 2 ) inside the container 1 .

The height H1 of the left plate 200 and the height H2 of the right plate 300 are smaller than the height H3 of the inside of the container 1 . Accordingly, the upper end of the left plate 200 and the upper end of the right plate 300 are arranged to be spaced apart from the inner wall of the container 1 by a predetermined distance in the vertical direction (z).

Due to the load of the liquefied cargo, the flexi tank ( 3 in FIG. 2 ) may press the flexi bucket 10 . In particular, the pressure due to the liquefied cargo may be greatly applied to the left plate 200 and the right plate 300 of the flexi bucket 10 .

5 is a view showing the flexi bucket 10 in close contact with the inner wall of the container (1).

2 and 5, the flexi bucket 10 is made of a plastic material, and includes an inner wall (AP) connecting the outer shell (OP) and the endothelium (IP) and the outer shell (OP) and the endothelium (IP). can And the flexi bucket 10 may include a hollow CA surrounded by an outer shell OP, an endothelium IP, and an inner wall AP. Since the flexi bucket 10 has waterproof and oil-proof properties, even if the liquefied cargo leaks from the flexi tank (3 in FIG. 2), it is possible to minimize or prevent leakage of the liquefied cargo into the container and further to the outside. .

Since the flexi bucket 10 covers both the front and rear left and right sides of the flexi tank (3 in FIG. 2), and does not absorb liquid cargo, unlike paper-made corrugated cardboard, the liquid cargo more effectively leaks to the inner surface of the container or to the outside. can be minimized or prevented.

In addition, the flexi bucket 10 includes a hollow (CA) therein, can absorb external shocks applied to the flexi tank (3 in FIG. 2 ), and is disposed on the inner wall of the container 1 or the floor of the transport environment Due to the protruding structure or sharp objects, it is possible to prevent the flexi tank (3 in FIG. 2) from being damaged. In addition. Since the flexi bucket 10 according to the embodiment includes a hollow (CA), it has better thermal insulation properties than a corrugated cardboard made of paper, thereby making it easier to maintain the temperature of the liquid cargo.

Meanwhile, on both sides of the inner surface of the container 1 , the protruding portion 1a and the non-protruding portion may be disposed at regular intervals along the front-rear direction x. Due to the protrusion 1a, in a state in which the pressure due to the liquefied material is continuously applied, stress is concentrated in a partial area of the flexi bucket 10 corresponding to the boundary between the protrusion 1a and the non-protrusion, in the area The flexi bucket 10 may be damaged.

3 and 5 , in order to prevent this, the flexi bucket 10 according to the embodiment includes a fifth folded portion F5 on the left plate 200 and the right plate 300 , respectively. The plurality of fifth folded portions F5 are arranged at regular intervals along the front-rear direction x. The fifth folded portion F5 may be disposed to be elongated in the vertical direction z on the left plate 200 or the right plate 300 .

The fifth folded portion F5 has a ratio with the protrusion 1a of the inner wall AP of the container 1 alternately arranged along the front-rear direction x when the flexi bucket 10 is mounted on the container 1 . It is disposed corresponding to the boundary between the projections. The fifth folded portion F5 corresponds to the pressure applied to the left plate 200 and the right plate 300, respectively, and is positioned between the protrusion 1a and the protrusion 1a to form the left plate 200 or the right plate 300. ) to cause deformation of the left plate 200 or the right plate 300 so that it is in close contact.

This flexi bucket 10 not only increases the adhesion between the plexi-tank (3 in FIG. 2) and the plexi-bucket 10, but also increases the adhesion with the inner wall of the plexi-bucket 10 and the container 1, so the plexi-tank (Fig. Even if 3 of 2) is damaged, it is possible to effectively prevent leakage of liquid cargo to the outside of the flexi tank (3 in FIG. 2).

In addition, the front-rear width D2 of the hollow CA in the region corresponding to the non-protruding part of the left plate 200 or the right plate 300 is in the front-rear direction of the hollow CA in the region corresponding to the protruding part 1a. The width D1 may be large. This is to increase the amount of deformation of the left plate 200 or the right plate 300 in response to the pressure applied from the flexi tank (3 in FIG. 2) in the region corresponding to the non-protrusion of the left plate 200 or the right plate 300. , there is an advantage of increasing the adhesion to the inner wall (AP) of the flexi bucket 10 and the container 1 in the non-protrusion.

6 is a view showing the leaked liquid cargo accumulated in the bottom plate (100).

2 and 6 , the reinforcing plate 1000 may be further coupled to the lower surface of the bottom plate 100 .

The bottom plate 100 may include a plurality of holes H. The hole H and the reinforcing plate 1000 may form a space for accommodating the liquid leaked from the flexi tank (3 of FIG. 2 ). Even if the liquid cargo is exposed in the Flexitank (3 in FIG. 2), because it is accommodated in the receiving space formed by the hole (H) and the reinforcing plate (1000). It is possible to prevent the leaked liquid cargo from flowing to the outside and contaminating the container 1 or the warehouse.

As described above, with reference to the accompanying drawings with respect to the flexi bucket 10 for a liquefied cargo tank according to one preferred embodiment of the present invention was looked at in detail.

It is to be understood that one embodiment of the present invention described above is illustrative in all respects and not restrictive, and the scope of the present invention will be indicated by the following claims rather than the foregoing detailed description.
