[0022] like Figures 1 to 4 As shown, this embodiment provides a tank container that facilitates loading and unloading, enabling rapid and residue-free loading and unloading, reducing losses during loading and unloading. The valves can be linked to avoid personnel having to climb to heights for operation, thus ensuring personnel safety.

[0023] A tank container for easy loading and unloading includes a tank body 1, with a loading and unloading port 101 located near the bottom of the tank body 1. The tank body 1 also includes: The emergency shut-off valve 200 includes a first rotating handle 201 and a shut-off valve body 202. The inlet of the shut-off valve body 202 is connected to the loading and unloading port 101. The emergency shut-off valve 200 is used to shut off the loading and unloading of the tank body 1 in case of an emergency, such as a fire, to prevent the fire from igniting the liquid fuel and causing the tank to explode. When in use, the emergency shut-off of loading and unloading of the tank body 1 can be achieved by turning the first rotating handle 201 to close the shut-off valve body 202. When loading and unloading, the shut-off valve body 202 is in the open state.

[0024] The wafer-type butterfly valve 300 includes a second rotating handle 301 and a butterfly valve body 302. The inlet of the butterfly valve body 302 is connected to the outlet of the shut-off valve body 202. The wafer-type butterfly valve 300 is used for loading and unloading materials inside the tank body 1. When in use, the wafer-type butterfly valve 300 can be opened by turning the second rotating handle 301, and the wafer-type butterfly valve 300 can be closed by turning the second rotating handle 301 in the opposite direction. The loading and unloading of materials in the tank body 1 is realized by opening and closing the wafer-type butterfly valve 300.

[0025] The vapor phase valve 400 is located on the top of the tank body 1. The switch of the vapor phase valve 400 is connected to the second rotary handle 301 through a stainless steel gas pipe. This connection method is existing technology in the field and will not be described in detail here. The vapor phase valve 400 is used to open and control the liquid flow rate during loading and unloading of materials in the tank body 1.

[0026] During the logistics transportation of the tank container, the gas phase valve 400 is normally closed, and the shut-off valve body 202 of the emergency shut-off valve 200 is also normally closed. When it is necessary to load or unload the liquid medium inside the tank container 1 upon arrival at the destination, connect one end of the loading / unloading hose to the outlet of the butterfly valve body 302. After connection, turn the first rotating handle 201 to open the emergency shut-off valve 200 and turn the second rotating handle 301 to open the wafer butterfly valve 300. The wafer butterfly valve 300 drives the gas phase valve 400 through the air pipe, thereby opening the gas phase valve 400. At this time, the valve body is fully open, and the air pressure inside the tank container 1 is the same as the air pressure of the external environment. The liquid medium inside the tank container 1 can flow out of the tank container under the action of gravity, realizing unloading. In case of emergency, the first rotating handle 201 can be turned to close the emergency shut-off valve 200, stop the unloading operation, and ensure the safety of the unloading process.

[0027] The connection port of the gas phase valve 400 is connected to the pressurizing device, which is used to pressurize the inside of the tank body 1 through the gas phase valve 400 to accelerate the unloading flow rate.

[0028] The pressurization device includes a nitrogen booster, the pressure outlet of which is connected to the gas phase valve 400 via a pipeline.

[0029] During unloading, with the wafer-type butterfly valve 300, emergency shut-off valve 200, and gas phase valve 400 all open, the nitrogen pressurization device is turned on. The nitrogen pressurization device injects nitrogen pressure into the tank body 1 from the pressure outlet. For example, when the injected nitrogen pressure is 0.1~0.2MPa higher than the internal pressure of the tank body 1, the flow rate of the liquid medium inside the tank body 1 can be accelerated.

[0030] The top of the tank body 1 is also equipped with a safety valve (not shown in the figure). When the liquid inside the tank body 1 encounters a dangerous situation that causes the internal pressure of the tank body 1 to increase (e.g., ≥0.44Mpa), the safety valve will automatically pop up and start to release pressure until the internal pressure of the tank body 1 is ≤0.4Mpa, which can effectively prevent the occurrence of explosions and other situations.

[0031] The emergency shut-off valve 200 is equipped with a fusible plug. The melting point of the fusible plug can be set as needed, for example, 75±5 degrees Celsius. If a fire occurs during the unloading process and the staff does not have time to close the emergency shut-off valve 200, the fusible plug will melt and automatically close the emergency shut-off valve 200 when the temperature rises to the melting point of the fusible plug.

[0032] The emergency shut-off valve 200 can also be an electric emergency shut-off valve 200. The electric emergency shut-off valve 200 is equipped with a communication unit and is connected to a remote control terminal through the communication unit. The remote control terminal can be an industrial control computer, a computer, a mobile phone, etc. The staff can remotely operate the electric emergency shut-off valve 200 to avoid the situation where they cannot get to the scene in time to manually shut off the emergency shut-off valve 200.

[0033] A dust cover 500 is movably connected to the outlet of the butterfly valve body 302 of the wafer-type butterfly valve 300. During tank container logistics transportation, the dust cover 500 covers the outlet of the butterfly valve body 302, effectively preventing dust and ash accumulation at the outlet of the butterfly valve body 302, and preventing contamination of the liquid medium during subsequent unloading. As shown in the figures, the dust cover 500 has two symmetrical buckles 501 on its periphery. A protrusion (not shown in the figure) is provided on the butterfly valve body 302 at the position corresponding to the buckles 501. When the buckles 501 are fastened to the protrusion, the dust cover 500 can be fixed to the butterfly valve body 302.

[0034] The tank body 1 is equipped with a hoisting frame on the outside. The tank body 1 is inclinedly connected to the hoisting frame, and the unloading port is located at the lower end of the tank body 1. The inclined setting makes it easy for all the liquid medium in the tank body 1 to flow out of the tank body 1, and prevents liquid residue in the tank body 1.

[0035] This application uses a wafer-type butterfly valve 300 and an emergency shut-off valve 200 installed at the bottom of the tank body 1, and a gas phase valve 400 and a safety valve installed at the top of the tank body 1. Through the linkage of the valves, loading and unloading can be realized quickly, improving production efficiency, while ensuring production safety during the rapid loading and unloading process. Moreover, the structure of this application is simple, easy to install, and easy to put into actual production.
