Referring to FIG. 1, the dangerous goods container 1 of an embodiment to which the liner bag assembly for a dangerous goods container according to the present invention is applied includes a container body 200 having a wall made of a thermoplastic material by a blow molding method, and a container body A lattice frame 300 made of metal that surrounds the 200 to support and protect it from the outside, a base pallet 400 on which the container body 200 is located and connected to the lattice frame 300, and the container body 200 ) and a cap 100 that closes the container opening 201 formed on the top.

2 is an exploded perspective view of a cap for a dangerous goods container according to an embodiment to which a liner bag assembly for a container for dangerous goods according to the present invention is applied, and FIG. 3 is a cross-sectional view based on a central axis.

2 and 3, the cap 100 is a main cap 110 coupled to the opening and an auxiliary cap coupled to an insert hole 111 formed in the center of the main cap 110 ( 120).

Here, the insert hole 111 has a shape penetrating the central portion of the main cap 110 vertically, and injects dangerous substances such as chemicals and wastes into the container body 200, or is accommodated in the container body 200. It may be used for the purpose of passing a hose that discharges dangerous materials or suctions the inside of the container body 200 after discharging dangerous materials.

The injection hole 111 may have a thread formed on the inner periphery, and the auxiliary cap 120 is screwed to the thread formed in the injection hole 111 to be coupled to the auxiliary cap 120. As a result, the injection through hole 111 is closed.

Here, when receiving or withdrawing dangerous materials such as chemical waste, one or more caps selected from the auxiliary cap 120 or the main cap 110 may be opened according to the type and usage of the dangerous materials to inject or discharge the dangerous materials.

The main cap 110 is provided at the center of the main cap body 112, the upper plate 113 closing the upper side, and the upper plate 113, and has a screw thread formed therein, and extends to the lower side of the upper plate 113. An insert hole 111 protruding, a connector 114 extending from the injection hole 111 at the bottom of the injection hole 111, and injection into one side of the upper plate 113 It includes peripheral holes 115 and 116 formed through the through hole 111 in the same axial direction.

Here, a screw thread is formed on the inner surface of the main cap body 112 to engage and screw the container opening 201, and between the main cap body 112 and the container opening 201, the main cap O-ring (O- By combining the ring) 130, sealing performance can be improved while preventing leakage of dangerous substances.

In addition, the connection pipe 114 is formed to extend below the injection through hole 111, and may be coupled to the liner bag nipple 10 to be described later by forcible coupling according to close contact. At this time, in order to prevent the forcibly coupled liner bag nipple 10 from being separated by unintended force, a separation prevention groove 115 may be formed on the outer circumference of the connection pipe 114.

The auxiliary cap 120 is detachably coupled to the injection hole 111 formed in the central portion of the main cap 110 .

The auxiliary cap 120 includes a head portion 121 formed with a handle and the like to facilitate rotation by screwing, and an auxiliary cap coupling portion 122 coupled to the injection through hole 111.

Here, the auxiliary cap 120 has a thread formed on its outer circumferential surface to be screwed with the injection hole 111 of the main cap 110, and the head portion 121 is inserted into the injection hole 111 to rotate the auxiliary cap 120. The cap 120 may be coupled to the main cap 110.

In addition, sealing performance may be improved by coupling an auxiliary cap O-ring 140 between the main cap 110 and the auxiliary cap 120 .

Peripheral holes 115 and 116 are disposed between the outer surface of the connector 114 and the inner surface of the container opening 201, and the peripheral holes 115 and 116 are connected to a vacuum line (not shown in the drawing). ) for connection.

After the liner bag 20 is installed inside the container body 200, air remaining between the inner wall of the container body 200 and the liner bag 20 is sucked using a vacuum pump (or suction device) to 20) is formed to adhere the outer surface to the inner wall of the container body 200, and a screw thread may be formed therein so that the vacuum line of the vacuum pump can be connected.

For example, the peripheral through-holes 115 and 116 may be formed in two as shown, and may be formed in one or three or more depending on the purpose of use, but are not limited thereto.

Insert nuts 151 and 152 may be coupled to each of the peripheral through holes 115 and 116 to maintain a certain level of vacuum pressure formed inside the container body 200 by a vacuum line. At this time, the insert nuts 151 and 152 may be screwed into the peripheral through holes 115 and 116 or coupled to each other in an interference fit manner.

4 is a perspective view showing the configuration of a liner bag assembly for a dangerous goods container according to the present invention.

Referring to FIG. 4 attached, the liner bag assembly for a dangerous goods container according to the present invention includes a liner bag nipple 10 and a liner bag 20.

The linerback nipple 10 is coupled to a connector 114 protruding downward inside the center of the cap 100, and the linerback nipple 10 has a cylindrical body 11 having a predetermined thickness. and a flange 12 formed on one side of the body 11.

The liner bag nipple 10 may be made of metal or synthetic resin, and the inner circumferential surface adheres closely to the outer circumferential surface of the connection pipe 114 to be coupled.

At this time, a stop protrusion (13, see FIG. 3) corresponding to the separation prevention groove 115 formed on the outer periphery of the connector 114 is formed on the inner circumferential surface of the body 11 of the liner bag nipple 10. That is, the stopping protrusion 13 protrudes toward the central axis, and in the process of inserting the body 11 of the liner bag nipple 10 into the connecting pipe 114, the stopping protrusion 13 is formed with a separation prevention groove ( 115), the liner bag nipple 10 can be maintained coupled to the connection pipe 114.

The liner bag 20 may be a bag-shaped PE film installed inside the container body 200, and the dangerous goods container (hereinafter referred to as IBC Tank) may be reused several times by replacing only the liner bag 20.

The liner bag 20 may be coupled to the flange 12 of the liner bag nipple 10 using a binder such as an adhesive.

5 is a cross-sectional view of a state in which the liner bag assembly for a dangerous goods container according to the present invention is coupled to a cap.

Referring to the attached FIG. 5 , the body 11 of the liner bag nipple 10 is fitted into and coupled to the connection pipe 114, and the liner bag 20 is coupled to the flange 12.

Accordingly, with reference to FIG. 5 , a process of installing the liner bag assembly for a dangerous goods container according to the present invention to the container body 200 and a process of accommodating dangerous goods will be described.

After the main cap 110 is separated from the container body 200, the liner bag 20 coupled with the liner bag nipple 10 is inserted into the container body 200. After separating the auxiliary cap 120 from the separated main cap 110, the main cap 110 is coupled to the container body 200 while holding the liner bag nipple 10 through the injection through hole 111, and then , The liner bag nipple 10 is coupled to the connection pipe 114.

After removing the insert nuts 151 and 152 coupled to the peripheral through-holes 115 and 116 of the main cap 110, and then connecting the vacuum line connected to the vacuum pump to the peripheral through-holes 115 and 116, the vacuum pump is operated. When operated, negative pressure is generated between the outer side of the liner bag 20 and the inner surface of the container body 200, and the generated negative pressure causes the outer surface of the liner bag 20 to come into close contact with the inner wall of the container body 200. do.

In a state where the outer surface of the liner bag 20 is in close contact with the inner wall of the container body 200, the vacuum line is removed from the peripheral through holes 115 and 116, and the vacuum line is removed to maintain the close contact state. Insert nuts 151 and 152 are inserted and coupled to the through holes 115 and 116 .

Thus, after injecting a hazardous substance into the liner bag 20 through the injection hole 111, the injection hole 111 is sealed using the auxiliary cap 120.
