DETAILED DESCRIPTION OF THE INVENTION

[0030] Typical embodiments embodying the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments, all of which do not depart from the scope of the present invention, and the descriptions and illustrations therein are essentially for illustrative purposes and not intended to limit the present invention.

[0031] To further illustrate the principle and structure of the present invention, the preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0032] Referring to Figure 1 and Figure 2 , the present invention provides a tank container, which mainly includes a frame (not shown in the figure), a tank body 1 disposed within the frame, and a discharging device 2. By sinking the discharging device 2 to protrude from the bottom of the tank body 1 and the heating function of the discharging device 2, smooth discharging and rapid emptying are achieved.

[0033] Among them, the tank container can be a standard tank container (ISO) or an exchangeable tank container (SWAPBODY).

[0034] The structure of the frame can adopt related technologies and will not be elaborated here one by one.

[0035] The tank body 1 is mainly used to carry liquid media, such as liquid chemicals, liquid foods, various petroleum products, and liquor goods, etc. For the convenience of description, the length direction of the tank body 1 is defined as the longitudinal direction, and the width direction of the tank body 1 is defined as the transverse direction.

[0036] A discharge opening is provided at the bottom of the tank body 1. Specifically, in this embodiment, the discharge opening is provided at the transverse center line of the tank body 1. In other embodiments, the position of the discharge opening can be specifically set according to the actual situation.

[0037] The discharging device 2 is connected to the discharge opening and communicates with the inside of the tank body 1, so as to be able to discharge the liquid medium inside the tank body 1 to the outside.

[0038] The discharging device 2 includes a discharging passage 21 and a heating circulation passage. The discharging passage 21 is used for the liquid medium inside the tank body 1 to flow and be discharged to the outside. The discharging passage 21 is heated through the heating circulation passage, thereby heating the liquid medium, melting the liquid medium, reducing the viscosity of the liquid medium, and then being able to discharge more smoothly and quickly. It is especially suitable for unloading some viscous materials, avoiding their condensation at lower temperatures, resulting in difficult discharging, incomplete discharging, or slow discharging speed.

[0039] The following is a detailed introduction.

[0040] The discharging passage 21 includes a discharging pipe 211, a discharging flange 212, a reinforcing plate 213, a sealing plate 214, and a reinforcing plate 215.

[0041] The discharge pipe 211 is arranged at the bottom of the tank body 1 and protrudes downward from the tank body 1. That is, the discharge pipe 211 is sunk so that there is a height difference between the bottom of the discharge pipe 211 and the lowest point of the bottom of the tank body 1, that is, the bottom of the discharge pipe 211 is located below the lowest point of the bottom of the tank body 1, so that there is a certain distance between the bottom of the discharge pipe 211 and the lowest point of the bottom of the tank body 1, and then the last remaining liquid in the tank body 1 can flow smoothly into the discharge pipe 211 due to the action of gravity.

[0042] The discharge pipe 211 extends along the transverse direction of the tank body 1, and its two ends are a communication end and a discharge end respectively. The communication end is located at the discharge port of the tank body 1 and is communicated with the inside of the tank body 1. The discharge end is communicated with the outside, and then the liquid medium in the tank body 1 can be discharged outward.

[0043] Further, the discharge pipe 211 is inclined to make the liquid medium discharge more smoothly. Specifically, the discharge pipe 211 is inclined downward from the communication end to the discharge end.

[0044] The included angle α between the discharge pipe 211 and the horizontal plane is 0.5° to 90°.

[0045] In this embodiment, the cross-sections of the communication end and the middle area of the discharge pipe 211 are both arc-shaped, the cross-section of the discharge end is circular, and the radian of the discharge pipe 211 matches the radian of the bottom of the tank body 1. The discharge pipe 211 can be prepared by cutting a circular pipe, that is, by obliquely cutting a circular pipe approximately along its axial direction, or can be made by winding a plate.

[0046] The discharge flange 212 is arranged at the discharge end. Because the discharge pipe 211 is inclined, the discharge flange 212 is also inclined with respect to the horizontal plane.

[0047] The reinforcing plate 213 is fixed near the discharge port at the bottom of the tank body 1 and is adapted to the radian of the bottom of the tank body 1, and is used to increase the strength near the discharge port at the bottom of the tank body 1.

[0048] The sealing plate 214 is arranged between the discharge pipe 211 and the reinforcing plate 213, and is used to seal the gap between the discharge pipe 211 and the tank body 1 caused by the sinking of the discharge pipe 211, so that a passage is formed among the discharge pipe 211, the sealing plate 214, the reinforcing plate 213 and the bottom of the tank body 1 for the liquid medium to flow.

[0049] In this embodiment, the sealing plate 214 is generally U-shaped, including a transition part and extension parts on both sides of the transition part. The extension parts are located on both sides of the discharge pipe 211, and the transition part is located at the communication end.

[0050] The reinforcing plate 215 is disposed between the discharge pipe 211 and the reinforcing plate 213, that is, between the discharge pipe 211 and the bottom of the tank body 1. Specifically, the reinforcing plate 215 is close to the discharge end of the discharge pipe 211 and has a gap with the discharge flange 212 to enhance the stability between the discharge end of the discharge pipe 211 and the tank body 1.

[0051] In other embodiments, the reinforcing plate 215 can also be disposed at a position away from the discharge end. Specifically, it can be reasonably set according to the actual situation and within the allowable space.

[0052] Specifically, the reinforcing plate 215 extends vertically and has a groove. The reinforcing plate 215 is sleeved on the outer periphery of the discharge pipe 211 and is fixed to the reinforcing plate 213. The discharge pipe 211 is located in the groove of the reinforcing plate 215, thereby realizing that the reinforcing plate 215 is sleeved on the outer periphery of the discharge pipe 211.

[0053] In this embodiment, the discharge passage 21 protrudes downward from the bottom of the tank body 1, that is, a sunken structure, and the inclined setting of the discharge pipe 211 enables the liquid medium in the tank body 1 to be discharged more smoothly according to gravity.

[0054] The heating circulation passage is located at the bottom of the discharge passage 21 to heat the liquid medium in the discharge passage 21.

[0055] The heating circulation passage includes a heating pipe 221, an input pipe 223, an output pipe 224, a heat source supply unit, an input connection pipe 225, and an output connection pipe 226.

[0056] The heating pipe 221 is fixed to the bottom of the discharge pipe 211. Specifically, in this embodiment, the heating pipe 221 includes a sleeve that is arranged in a circle and a cover plate 222 that covers the sleeve. In other embodiments, the sleeve can also be arranged in two circles or other numbers, which is specifically set according to actual needs.

[0057] The sleeve is fixed to the bottom of the discharge pipe 211. Specifically, defining the vertical direction as the axial direction of the sleeve, its two axial ends are respectively connected to the bottom of the discharge pipe 211 and the cover plate 222. An inlet and an outlet are provided on the circumference of the sleeve, and there is a gap between the inlet and the outlet. The inlet and the outlet of the sleeve constitute the inlet and the outlet of the heating pipe 221. In this embodiment, the inlet and the outlet are arranged opposite to each other, that is, the outlet and the inlet are arranged on both sides.

[0058] The cover plate 222 covers the sleeve, and the cover plate 222, the sleeve, and the discharge pipe 211 form a closed heating space. Exemplarily, the cover plate 222 covers the bottom of the sleeve to cover the sleeve. Or, the cover plate 222 is fixedly connected to the inner circumference of the sleeve, and there is a height difference between the cover plate 222 and the discharge pipe 211.

[0059] Refer to Figure 3, in an exemplary embodiment, the cover plate 222 is plate-shaped. Further, the heating circulation path further includes a plurality of reinforcing pipes 229 arranged at intervals. Each reinforcing pipe 229 is connected to the cover plate 222 and extends into the heating space to be connected to the discharge pipe 211. That is, one end of each reinforcing pipe 229 is located at the bottom of the cover plate 222, and the other end extends upward to the discharge pipe 211 for fixed connection. The arrangement of the reinforcing pipes 229 increases the connection strength between the heating pipe 221 and the discharge pipe 211.

[0060] Refer to Figure 4 , in another exemplary embodiment, the cover plate 222 includes a plurality of convex portions arranged at intervals and a connecting portion connecting adjacent convex portions. Among them, the convex portions protrude upward beyond the connecting portion, and the top of the convex portion is fixedly connected to the discharge pipe 211. The use of this cover plate 222 structure increases the connection strength between the heating pipe 221 and the discharge pipe 211.

[0061] Refer to Figure 5 , in yet another exemplary embodiment, the heating pipe 221 covers the surface of the discharge pipe 211. Specifically, the heating pipe 221 includes a plurality of protrusions arranged at intervals and a transition portion connecting adjacent protrusions. Among them, the protrusions protrude upward beyond the transition portion, and the top of the protrusion is fixedly connected to the discharge pipe 211. And the outlet and inlet of the heating pipe 221 are arranged at intervals and are both arranged on the transition portion. Specifically, the forming method of the heating pipe 221 is as follows: Provide a jacket plate with holes opened. First, cold-draw the holes to a certain depth, and then weld the heating pipe 221 to the outer surface of the side discharge pipe 211 by laser welding at each hole. When welding, reserve two holes as the inlet and outlet of the heating pipe 221 respectively.

[0062] After laser welding the holes, inflate through the reserved holes to form a space between the transition portion and the heating pipe 221, thereby forming a heating space.

[0063] The heating medium enters the heating space from the inlet, heats the liquid medium in the discharge pipe 211, and then flows out of the heating space from the outlet.

[0064] The heat source supply unit is used to provide the heating medium. Specifically, the heating medium can be a gas, such as water vapor. The heating medium can also be a liquid, such as ethylene glycol or hot water. The heating medium can also be selected according to actual needs.

[0065] The heat source supply unit includes an input interface and an output interface. The output interface is used to output the heated heating medium outward, and the input interface is used to receive the heating medium that has cooled down after heat exchange.

[0066] There are multiple input connecting pipes 225, and the multiple input connecting pipes 225 are arranged at intervals along the transverse direction of the tank body 1, and each input connecting pipe 225 extends longitudinally. In this embodiment, input connecting pipes 225 are arranged at both longitudinal ends of the discharge pipe 211.

[0067] All the input connecting pipes 225 are connected to the output interfaces of the heat source supply unit.

[0068] The input pipe 223 is connected to the inlet of the sleeve. At the same time, the input pipe 223 is communicated with the multiple input connecting pipes 225, so that the heating medium flows into the heating space. Specifically, in this embodiment, the input pipe 223 and the multiple input connecting pipes 225 are connected by a horizontally extending horizontal connecting pipe.

[0069] The output pipe 224 is connected to the outlet of the sleeve, so that the heating medium flows out of the heating space. That is, after the heating medium entering the heating space from the input pipe 223 exchanges heat with the liquid medium in the discharge pipe 211 and the temperature of the heating medium drops, it then flows out of the heating space through the output pipe 224.

[0070] There are multiple output connecting pipes 226, and the multiple output connecting pipes 226 are arranged at intervals along the transverse direction of the tank body 1, and each output connecting pipe 226 extends longitudinally. In this embodiment, output connecting pipes 226 are arranged at both longitudinal ends of the discharge pipe 211. And the input connecting pipe 225 and the output connecting pipe 226 at the same end of the discharge pipe 211 are arranged at intervals.

[0071] All the output connecting pipes 226 are connected to the output pipe 224. Specifically, in this embodiment, horizontal connecting pipes 227 are provided at both ends of the discharge pipe 211, and the input connecting pipes 225 and the output connecting pipes 226 at both ends of the discharge pipe 211 are connected to the corresponding horizontal connecting pipes 227.

[0072] Moreover, a baffle is provided in the horizontal connecting pipe 227 to separate the space in the horizontal connecting pipe 227 into an input space and an output space. The input connecting pipe 225 is communicated with the input space, and the output connecting pipe 226 is communicated with the output space.

[0073] The two horizontal connecting pipes 227 are also communicated with each other through a longitudinal connecting pipe 228.

[0074] The working principle of the heating circulation path is as follows: The heating supply unit provides the heating medium, which enters the heating space of the heating pipe 221 through the input connecting pipe 225 and the input pipe 223. Then, the flowing heating medium returns to the heat source supply unit from the outlet of the heating space through the output pipe 224 and the output connecting pipe 226. The heating of the liquid medium in the discharge pipe 211 and the circulation of the heating medium are realized.

[0075] The tank container in this embodiment adopts a sunken design, making the discharge pipe 211 protrude downward from the bottom of the tank body 1, so that the residual liquid in the tank body 1 can flow into the discharge pipe 211 due to gravity. And the discharge pipe 211 is inclined, so that the liquid medium can be discharged out more smoothly, thus achieving the purposes of easy discharging and fast discharging speed.

[0076] The liquid medium entering the discharge pipe 211 is heated by the heating medium in the heating circulation path, reducing the viscosity of the liquid medium, making the liquid medium flow out more easily, thus accelerating the discharging speed and reducing the residue of the liquid medium in the tank body 1.

[0077] As can be seen from the above technical solutions, the advantages and positive effects of the present invention are as follows:
