Description

Technical Field

[0001] This utility model relates to tank containers, specifically to a tank container loading and unloading system. Background Technology

[0002] Tank containers, as a type of storage and transportation equipment, can meet the needs of road, rail, and waterway transportation, and have the advantages of flexible and convenient transshipment. Based on the advantages of container transportation, the volume of container shipping has increased year by year in recent years, and the container market is vast.

[0003] Tank containers are generally used to transport liquid media. Currently, the unloading port (valve) of tank containers is located at one end of the tank bottom. If two tank containers are transported by truck, one cannot be unloaded from the truck. If two tank containers are transported by rail flatcar, the limited space at the end due to train coupling makes unloading inconvenient. Tank containers use a top-loading, bottom-unloading method, employing manually operated loading and unloading valves and a vent valve on the tank top (if there is no vent valve, a manhole must be opened for ventilation). Loading and unloading requires climbing to the top of the tank, making the operation complex, labor-intensive, and posing personal safety risks. To prevent overfilling during loading, the liquid level must be constantly monitored from the top of the tank; however, this monitoring is neither intelligent nor reliable, and the high labor intensity and personal safety risks of working on the tank top further exacerbate the problem. Furthermore, the vapor of the liquid is directly released into the air, causing atmospheric pollution. Utility Model Content

[0044] Those skilled in the art should understand that these embodiments are merely used to explain the technical principles of this utility model and are not intended to limit the scope of protection of this utility model.

[0045] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0046] In the description of this utility model, it should be noted that the terms "first", "second", "third" and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0047] refer to Figure 1 The present invention provides a tank container loading and unloading system comprising two loading and unloading devices 2, an overflow protection device 3, an oil and gas recovery device 4, and two operation panels 5.

[0048] The tank body 1 of the tank container includes a cylindrical body and two end plates connected to both ends of the cylindrical body. The tank body 1 adopts a square-round cross-sectional shape that makes full use of the width and height limits of the container frame to increase the tank volume.

[0049] like Figure 1 and Figure 2 As shown, two loading and unloading devices 2 are symmetrically arranged below the tank body 1. Each loading and unloading device 2 includes a loading and unloading bottom valve 21, a connecting pipe 22, and a first quick connector 23. The two loading and unloading bottom valves 21 are respectively used to connect to two loading and unloading ports at the bottom of the tank body 1. The axes of the two connecting pipes 22 are both used to extend along the width direction of the tank body 1. The ends of the two connecting pipes 22 that are close to each other are respectively connected to the corresponding loading and unloading bottom valves 21, and the ends of the two connecting pipes 22 that are far apart from each other are respectively connected to the corresponding first quick connectors 23. The two first quick connectors 23 are respectively used to be arranged on both sides of the bottom of the tank body 1 along the width direction of the tank body 1. The first quick connectors 23 are matched with the user end. By setting two first quick connectors 23 on both sides of the bottom of the tank body 1 in the width direction, the problem of limited space and inconvenience in unloading operations due to the arrangement of the loading and unloading valve interface ends is solved. At the same time, setting one first quick connector 23 on each side of the bottom of the tank body 1 allows users to carry out loading and unloading operations from either side of the tank body 1 in the width direction, which greatly facilitates the loading and unloading of tank containers. Especially when transporting tank containers by rail, it solves the problem of inconvenience in loading and unloading caused by the difficulty in changing the position of tank containers during rail transport.

[0050] like Figure 1 and Figure 3As shown, the oil and gas recovery device 4 includes a vent valve 41, a pipe joint 42, a connecting pipe 44, and two second quick connectors 43. The vent valve 41 is installed on the top of the tank 1 and communicates with the interior of the tank 1. The pipe joint 42 is welded and fixed to the top of the tank 1. The vent valve 41 is connected to one interface of the pipe joint 42 through the pipe. The connecting pipe 44 includes an external pipe 442, which is fixedly installed below the tank 1 and extends along the width of the tank 1. Both ends of the external pipe 442 are connected to two second quick connectors 43, which are used for... The second quick connector 43 is installed on both sides of the bottom of the tank body 1 along the width direction of the tank body 1. It is matched with the user end. The external pipeline 442 is set on the outside of the tank body 1, which makes the structure more reliable. The connecting pipeline 44 also includes an internal pipeline 441, which is set inside the tank body 1. This arrangement can reduce the space occupied by the connecting pipeline 44 inside the container frame, thereby making full use of the container frame clearance and increasing the volume of the tank body 1. The internal pipeline 441 includes a first vertical section 4411, a first curved section 4412, a first connecting section 4413, and a second curved section connected in sequence. 4414, second vertical section 4415, third curved section 4416, second connecting section 4417, fourth curved section 4418, and third vertical section 4419; the first vertical section 4411, second vertical section 4415, and third vertical section 4419 are all used to extend along the height direction of the tank 1. The upper end of the first vertical section 4411 is connected to another interface of the pipe joint 42. The upper end of the first connecting section 4413 is connected to the lower end of the first vertical section 4411 through the first curved section 4412. The lower end of the first connecting section 4413 is used to extend towards the inner wall of the tank 1 and through the second curved section 4412. The curved section 4414 is connected to the upper end of the second vertical section 4415. The lower end of the second connecting section 4417 is connected to the upper end of the third vertical section 4419 via the fourth curved section 4418. The upper end of the second connecting section 4417 extends towards the inner wall of the tank 1 and is connected to the lower end of the second vertical section 4415 via the third curved section 4416. The lower end of the third vertical section 4419 is connected to the interface in the middle of the external pipeline 442 via a pipe joint, which is used for welding and fixing to the bottom of the tank 1. The upper part of the second vertical section 4415 is fixedly connected to the inner wall of the tank 1 via a pipe clamp. The internal pipeline 441 of the connecting pipeline 44 is set close to the wall and adopts a bent pipe structure, which meets the requirements of deformation coordination and can reduce the stress of the connection joint between the internal pipeline 441 and the tank 1 when the tank deforms during operation. The oil and gas recovery device 4 prevents the medium vapor from being directly emitted into the air and causing pollution to the atmospheric environment; the two second quick connectors 43 are set on both sides of the bottom of the tank 1 along the width direction of the tank 1, which makes the operation convenient and safe.

[0051] like Figure 1 , Figure 4 and Figure 5 As shown, two control panels 5 are respectively installed on both sides of the tank 1 along the width direction of the tank 1. The loading / unloading bottom valve 21 and the vent valve 41 are both pneumatically controlled valves.

The control panels 5 are equipped with a control air source interface 52, a loading / unloading bottom valve air circuit switch 53, a main air source switch 54, indicator lights, and a pressure gauge. The control air source interface 52 is used to connect to an air source. The main air source switch 54 is used to control the opening and closing of the main air circuit. After opening the main air source switch 54, the vent valve 41 opens. Then, opening... The loading / unloading bottom valve air circuit switch 53 can open the loading / unloading bottom valve 21 on the same side; the overflow protection device 3 is installed on the top of the tank 1 to monitor whether the medium in the tank 1 exceeds the specified filling amount during filling. The overflow protection device 3 is connected to two operation panels 5 through wires to transmit signals. The operation panel 5 is also equipped with an external interface 51 for the overflow protection device, which is used to connect to ground facilities. The tank 1 is equipped with an automatically monitored and controlled overflow protection device 3. When the filling medium exceeds the specified filling amount, it will automatically alarm and stop filling. It is not necessary for personnel to constantly observe the liquid level rise on the tank top. The monitoring and control is intelligent, safe and reliable, while reducing labor intensity and eliminating the safety risks to personnel from working on the tank top. The outside of the air pipe and wire is covered with a protective tube 6, which protects the air pipe and wire.

[0052] During the filling operation, the loading and unloading pipeline of the ground facility is connected to a first quick connector 23, and the oil and gas recovery pipeline of the ground facility is connected to a second quick connector 43 on the same side. The gas source and the overflow protection plug of the ground facility are respectively connected to the control gas source interface 52 and the overflow protection device external interface 51 on the same side of the operation panel 5. Then, the vent valve 41 and the loading and unloading bottom valve 21 on the same side are opened through the operation panel 5. Subsequently, the medium is filled into the tank 1 through the first quick connector 23, the connecting pipe 22 and the loading and unloading bottom valve 21 in sequence. At the same time, the oil and gas in the tank 1 are filled into the tank 1 through the vent valve 41 and the connecting pipe 43 in sequence. 2. The connecting pipe 44 and the second quick connector 43 are recovered to the ground facility. During the filling process, the overflow protection device 3 can automatically monitor whether the medium in the tank 1 exceeds the specified filling amount. When the filling medium exceeds the specified filling amount, the overflow protection device 3 will automatically alarm and stop filling. Then, the loading and unloading bottom valve 21 and the vent valve 41 will be closed by controlling the operation panel 5. Finally, the connection between the loading and unloading pipe and the first quick connector 23, the connection between the oil and gas recovery pipe and the second quick connector 43, the connection between the gas source and the control gas source interface 52, and the connection between the overflow protection plug and the overflow protection device external interface 51 are disconnected.

[0053] During unloading operations, the loading and unloading pipeline of the ground facility is connected to a first quick connector 23, the oil and gas recovery pipeline of the ground facility is connected to a second quick connector 43 on the same side, and the gas source is connected to the control gas source interface 52 on the same side of the operation panel 5. Then, the vent valve 41 and the loading and unloading bottom valve 21 on the same side are opened through the operation panel 5. Subsequently, the medium flows out of the tank 1 through the loading and unloading bottom valve 21, the connecting pipe 22 and the first quick connector 23 in sequence. At the same time, the pressure gas in the balance tank provided by the ground facility enters the tank 1 through the second quick connector 43, the connecting pipeline 44, the pipe joint 42 and the vent valve 41 in sequence. After the medium in the tank 1 is emptied, the loading and unloading bottom valve 21 and the vent valve 41 are closed through the operation panel 5. Finally, the connection between the loading and unloading pipeline and the first quick connector 23, the connection between the oil and gas recovery pipeline and the second quick connector 43, and the connection between the gas source and the control gas source interface 52 are disconnected.

The top of the tank body 1 is equipped with a vent valve 41. Both the loading and unloading bottom valve 21 and the vent valve 41 are pneumatically controlled to open and close, resulting in a high degree of automation. The loading and unloading operations of the tank container are all carried out on the ground, which simplifies the loading and unloading process, reduces labor intensity, and avoids the risk of personal safety injury from climbing the top of the tank.
