[0034] Although the present invention can be easily embodied as embodiments of different forms, only some of the specific embodiments are shown in the drawings and will be described in detail in this specification. It should be understood that this description should be regarded as an exemplary illustration of the principles of the present invention and is not intended to limit the present invention to that described herein.

[0035] Thus, a feature indicated in this specification is intended to illustrate one of the features of one embodiment of the present invention, rather than implying that every embodiment of the present invention must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features can be combined together to illustrate possible system designs, these features can also be used in other, not explicitly described, combinations. Thus, unless otherwise noted, the described combinations are not intended to be limiting.

[0036] In the embodiments shown in the accompanying drawings, directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of various components of the present invention are not absolute but relative. These descriptions are applicable when these components are in the positions shown in the accompanying drawings. If the descriptions of the positions of these components are changed, these directional indications will also change accordingly.

[0037] It should be noted that tank containers typically use steam / thermal fluid circulation heating or electric heating wires to heat or insulate the medium within the tank. Due to the unique environment of storage yards and transportation, it is difficult to maintain ultra-high-voltage, high-power power supplies, resulting in limited power consumption for electric heating. Therefore, electric heating cannot become the mainstream heating method for tank containers. The current mainstream heating method is to pass steam / thermal fluid through the tank container's piping to exchange heat with the tank wall, thereby heating the medium within the tank.

[0038] However, due to structural limitations, it is difficult for the pipeline to fully cover the tank structure. When the tank container adopts bottom unloading, the heat exchange pipe is a certain distance away from the unloading valve, which makes it difficult for the heat to be transmitted to the unloading valve and its surrounding areas. The existing structure basically hollows out the bottom flange, adds a hollow tube between the steam intake connecting pipe and the bottom flange, and connects them by welding. In order to avoid affecting the heating effect of the entire heating system, the diameter of the hollow tube needs to be as small as possible, and the cross-section of the steam intake connecting pipe is large, and the cross-section extending to the bottom flange is small, resulting in a small amount of steam flowing in and the heating effect is not significant. In addition, the steam pipe can be forced to extend to the head and surround the unloading valve, but this solution changes the direction of steam flow, causing the heating heat to be concentrated on the bottom unloading valve and its surrounding area, which will affect the efficiency of tank heating.

[0039] Therefore, the utility model provides a tank container, which can transfer heat to the vicinity of the discharge hole, eliminate the heating dead zone, quickly heat up the material and thus increase the fluidity of the material, avoiding the problem of high material viscosity and discharge blockage caused by uneven temperature at the discharge hole.

[0040] See Figures 1-4 The tank container includes a tank body and a heating system. The tank body is heated by the heating system, thereby solving the problem of unloading blockage.

[0041] The tank body has a space for holding materials, wherein the materials refer to liquid materials.

[0042] The bottom of the tank body is provided with a discharge hole which is communicated with the accommodating space, so as to discharge the material in the accommodating space outward through the discharge hole. The tank body is provided with a heating space around the discharge hole, and the heating space is located outside the tank body.

[0043] Specifically, the tank body includes a tank body, a flange 2 and a sealing plate 3. The tank body includes a cylinder 11 and sealing heads 12 arranged at both ends of the cylinder 11.

[0044] The bottom of the tank body has a through hole, and flange 2 is positioned there. Part of the through hole is positioned on the head 12, meaning that at least a portion of flange 2 is positioned there. In this embodiment, most of flange 2 is positioned on the head 12, with a portion positioned on the cylinder 11. In other words, flange 2 is positioned at an angle.

[0045] The flange 2 is provided with a through hole, which constitutes a discharge hole. The through hole is axially continuous with the flange 2. In this embodiment, the cross section of the flange 2 is circular. It can be understood that the flange 2 is a cylindrical structure with a certain wall thickness.

[0046] The bottom of the flange 2 is provided with a groove, the opening of the groove is downward. Specifically, the groove is provided with a circle along the circumference of the flange 2.

[0047] The sealing plate 3 is arranged at the opening of the groove to close the groove to form a heating space.

[0048] Please continue reading Figure 4 The sealing plate 3 includes a protective plate 31 and a cover plate 32 arranged in sequence. The cover plate 32 is welded to the flange 2, and the protective plate 31 is close to the heat pipe 5 located in the heating space. The material of the protective plate 31 is metal or high-temperature resistant non-metal.

[0049] Since the cover plate 32 is welded to the flange 2 , when the two are welded, the protective plate 31 isolates welding sparks from penetrating into the groove and causing the heat pipe 5 to burn through and fail, thereby ensuring the effectiveness of the heat pipe 5 .

[0050] The shape and size of the heating space can be specifically selected according to the shape and size of the heat pipe 5 to be placed.

[0051] For example, in this embodiment, the cross-sectional profile of the heating space is a right-angled trapezoid, that is, the inner wall of the heating space close to the discharge hole is parallel to the axial direction of the flange 2, and the outer wall away from the discharge hole is inclined downward from the inside to the outside. The top wall of the heating space is perpendicular to the axial direction of the flange 2, and the bottom wall of the heating space is the sealing plate 3.

[0052] The heating system includes a connecting pipe 4, a heat pipe 5, and a sealing plate 3. The connecting pipe 4 is used to circulate the heating medium. The heat pipe 5 is partially located within the heating space and partially extends into the connecting pipe 4. The heat pipe 5 serves as a heat transfer channel, transferring heat from the heating medium within the connecting pipe 4 to the vicinity of the discharge hole. This heat transfer heats the structures near the discharge hole, reducing the viscosity of the material and increasing its fluidity, allowing it to flow smoothly out of the discharge hole, avoiding blockage and ensuring smooth discharge. This heating system achieves these effects without changing the existing heating structure.

[0053] A connecting pipe 4 is provided at the bottom of the tank body for circulating a heat medium. The heat medium may be steam or a heat transfer fluid. The heat transfer fluid may be a mixed aqueous solution of dichromate, a mixed aqueous solution of permanganate, ethylene glycol, dichloromethane, distilled water, oil, ethanol, or methanol.

[0054] The connecting pipe 4 includes an inlet and an outlet. The inlet is used for the heat medium to enter, and the outlet is used for the heat medium to be discharged after providing heat and cooling.

[0055] Specifically, the connecting pipe 4 includes a plurality of longitudinal pipes and a plurality of connecting pipes. Each longitudinal pipe extends in the longitudinal direction of the tank body, and two adjacent longitudinal pipes are connected via a connecting pipe. In this embodiment, the plurality of longitudinal pipes are sequentially connected via the connecting pipes.

[0056] The heat pipe 5 is partially located within the heating space and partially located outside the heating space and extends into the connecting pipe 4 to contact the heat medium. The end of the heat pipe 5 inside the connecting pipe 4 is closed, which is used to receive heat from the heat medium and transfer it to the heat pipe 5 in the heating space, thereby heating the material near the discharge hole.

[0057] The heat pipe 5 is made of copper, aluminum or stainless steel. The heat pipe 5 is made of the above-mentioned material with high thermal conductivity so that the heat of the heat medium can be better transferred to the heating space, thereby heating the material.

[0058] Specifically, the heat pipe 5 includes a heating portion 51 located in the heating space and at least one conducting portion 52 located outside the heating space. One end of the conducting portion 52 is connected to the heating portion 51, and the other end extends into the connecting pipe 4.

[0059] The number of heating units 51 can be one or more. When there are multiple heating units 51, the multiple heating units 51 are stacked in the vertical direction. In this embodiment, the multiple heating units 51 are specifically stacked in the axial direction of the flange 2. The number of heating units 51 can be set according to the actual situation and needs of the tank.

[0060] Please continue reading Figure 3When there are multiple conducting parts 52, the conducting parts 52 are spaced apart along the circumference of the heating part 51. The more conducting parts 52 there are, the more heat transfer paths there are, and the heat can be transferred to the flange 2 more quickly. The number of conducting parts 52 is set according to the specific actual situation.

[0061] Each conducting portion 52 can extend into a longitudinal pipeline respectively.

[0062] Furthermore, the flange 2 is provided with a receiving channel for the conduction portion 52 of the heat pipe 5 to pass through, and the receiving channel is communicated with the heating space. In this embodiment, the receiving channel extends along the radial direction of the flange 2.

[0063] Among them, one receiving channel can only receive one conducting portion 52, or can receive multiple conducting portions 52. The number of receiving channels can be set according to the number of conducting portions 52. When there are multiple receiving channels, the multiple receiving channels are spaced apart along the circumference of the flange 2.

[0064] The shape of the heat pipe 5 can be cylindrical or flat tube.

[0065] The heat pipe 5 is cylindrical, and a sealing layer is provided between the heat pipe 5 and the tank body, which is resistant to high temperatures. The heat pipe 5 extends into the connecting pipe 4 through a conductive sleeve. The sealing layer is used to seal the receiving channel.

[0066] See Figure 1 A threaded seat is fixed to the connecting pipe 4. The threaded seat is hollow and communicates with the interior of the connecting pipe 4. A ferrule and nut are mounted on the outer sleeve of the heat pipe 5. The heat pipe 5 passes through the threaded seat, and the nut is threadedly connected to the threaded seat. When the ferrule and nut are placed over the heat pipe 5 and inserted into the connector body of the threaded seat, and the nut is tightened, the outer front end of the ferrule near the threaded seat mates with the conical surface of the connector body, and the inner edge evenly bites into the heat pipe 5, slightly deforming the heat pipe 5 and forming an effective seal.

[0067] The portion of the heat pipe 5 exposed between the connecting pipe 4 and the heating space is covered with a thermal insulation layer 7 or sleeved with a thermal insulation sleeve. Specifically, the outer periphery of the conductive portion 52 between the flange 2 and the connecting pipe 4 is covered with a thermal insulation layer 7 or sleeved with a thermal insulation sleeve. The thermal insulation layer 7 or sleeve prevents heat loss between the heat pipe 5 and the connecting pipe 4, ensuring that the flange 2 is the only condensation end that releases heat, thereby ensuring high heat conductivity.

[0068] In another embodiment, see Figure 2The heat conducting tube 5 is a flat tube, and an outer tube is provided on the heat conducting tube 5. The outer tube is made of non-metallic material and is resistant to high temperature and high pressure. A base is fixed to the connecting tube 4. The base is hollow and communicates with the interior of the connecting tube 4. A base is fixed to the tank body. The base is located outside the tank body, is hollow and communicates with the heating space. One end of the outer tube is provided with a nut threaded to the base, and the other end of the outer tube is provided with a nut threaded to the base. The base is fixed to the receiving channel.

[0069] Both the base and the pedestal are tapered threaded seats. One end of the heat conducting pipe 5 passes through the base, and the other end passes through the pedestal. The outer tube is sleeved on the outside of the heat conducting pipe 5. At the same time, one end of the outer tube is located outside the base, and the other end of the outer tube is located outside the pedestal. The two ends of the outer tube are respectively compressed and sealed by nuts, so that a closed cavity is formed between the connecting tube 4 and the flange 2.

[0070] When the heat pipe 5 is a flat pipe, the heat input power is larger, so that the heat conduction efficiency is greater.

[0071] When the heating portion 51 is a flat tube and has multiple layers, the local heat conduction efficiency of the flange 2 can be greatly improved.

[0072] Preferably, the end of the heat conducting pipe 5 extending out of the heating space is provided with a conducting portion, which extends into the connecting pipe 4 .

[0073] The conductive portion extends outwardly beyond the periphery of the heat pipe 5. That is, the cross-sectional area of ​​the conductive portion along the direction perpendicular to the axial direction of the heat pipe 5 is larger than that of the heat pipe 5. The above design increases the heat absorption area, thereby increasing the heat input at the heat absorption end.

[0074] Specifically, the size of the conductive portion and whether to provide it are determined according to the power level.

[0075] The conductive portion may be spherical or drum-shaped.

[0076] Furthermore, the heating space is also filled with a heat-conducting filler 6. The heat-conducting filler 6 is made of high-heat-conducting paste, high-heat-conducting metal powder or low-temperature solder.

[0077] For example, the thermally conductive filler 6 may be copper powder or aluminum powder with good thermal conductivity.

[0078] That is, the conductive portion 52 of the heat pipe 5 transfers heat from the heat medium to the heating portion 51. The heating portion 51 then transfers the heat to the heat-conducting filler 6, and then to the flange 2, thereby heating the material. In other words, the heat-conducting filler 6 serves as a heat transfer channel between the heating portion 51 and the flange 2.

[0079] When the thermal conductive filler 6 is a low-temperature solder, the periphery of the portion of the heat pipe 5 located in the heating space, i.e., the periphery of the heating portion 51, is also plated with nickel. The solder is preheated and melted by welding to fill the gap, and the solder becomes a heat transfer channel between the heat pipe and the flange 2.

[0080] The processing method between the flange 2 and the heat pipe 5 in this embodiment is as follows:

[0081] First, a flange 2 is machined to create a grooved flange 2. The heating portion 51 of the heat pipe 5 is then placed within the groove. The gap between the groove and the heating portion 51 is filled with a thermally conductive filler 6. The conductive portion 52 of the heat pipe 5 is then placed within the receiving channel. The protective plate 31 is then applied, followed by a cover plate 32 covering the opening of the groove. The assembled flange 2 and heat pipe 5 are then placed in a circulating water tank for welding. The welding process involves multiple layers and passes, with cooling intervals between passes before the next weld. Finishing is then performed, and finally, a seal is established between the heat pipe 5 and the flange 2.

[0082] In summary, the tank container has the following advantages:

[0083] The tank container includes a tank body and a heating system, which includes a connecting pipe 4 and a heat pipe 5. The connecting pipe 4 is used to circulate the heating medium. The heat pipe 5 is partially located within the heating space and partially extends into the connecting pipe 4. The heat pipe 5 serves as a heat transfer channel, transferring heat from the heating medium flowing through the connecting pipe 4 to the vicinity of the discharge port. This heats the structure near the discharge port, reduces the viscosity of the material, increases the fluidity of the logistics, and allows the material to flow smoothly out of the discharge port, avoiding blockage of the discharge port and ensuring smooth discharge. This heating system can achieve the above effects without changing the existing heating structure.
