Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tank containers, and in particular to a tank container and a bottom discharge box structure thereof. BACKGROUND

[0002] When shipping some special goods, such as medium with high melting point, a tank container needs to be equipped with an electric heating system to quickly heat or maintain the temperature of the goods, so as to ensure the quality of the goods and facilitate unloading. The electric heating system of the tank container usually adopts electric heating wires uniformly distributed on the outer wall of the tank body. However, the existing bottom discharge box is usually welded on the tank body or frame, and it is not convenient to subsequently construct the electric heating wires due to the small gap between the rear wall of the bottom box and the tank body (end cover). Even if the wires are constructed, it is not convenient for later maintenance.

[0003] Therefore, the existing tank container structure usually does not arrange heating wires in the area close to the bottom box of the tank body, resulting in relatively low temperature in the area of the rear wall of the bottom box and the bottom discharge area, which affects the unloading efficiency of the product and the quality of the goods. SUMMARY

[0004] The present application aims to provide a bottom discharge box structure of a tank container to solve the problem of low temperature in the bottom box area in the prior art affecting unloading.

[0005] The present application aims to provide a tank container with the above-mentioned bottom discharge box structure.

[0006] To solve the above technical problems, the present application adopts the following technical solutions:

[0007] A bottom discharge box structure of a tank container, the bottom of the tank body of the tank container is provided with a discharge port, the discharge port is provided with a bottom valve, the bottom discharge box structure is correspondingly arranged at the bottom valve, and the bottom discharge box structure comprises: a box body, which is hollow inside to accommodate the bottom valve; the box body has a forward opening, the box body has a rear wall facing the tank body; the rear wall and the tank wall have a spacing, and the rear wall is provided with an open mouth, which communicates with the inside of the box body; a sealing plate enters the inside of the box body through the opening and correspondingly covers the open mouth; the sealing plate is provided with a through hole for the bottom valve to pass out.

[0008] According to one aspect of the present application, the open mouth is opposite to the discharge port of the tank body.

[0009] According to one aspect of the present application, the contour of the open mouth is rectangular, and the size of the rectangle can provide sufficient working space for the arrangement of electric heating wires on the tank body.

[0010] According to one aspect of the invention, the box body includes two parallel side plates spaced apart, a top plate connected to the upper ends of the two side plates, a bottom plate connected to the lower ends of the two side plates, and a back plate connected to the rear ends of the two side plates; the back plate is the rear wall of the box body, and the back plate has an arc adapted to the outer wall of the can body.

[0011] According to one aspect of the present invention, both side panels and the top panel are double-layered structures, including an inner wall panel and an outer wall panel spaced apart from each other, with an insulation layer formed between the inner wall panel and the outer wall panel; an electric heating wire is disposed within the insulation layer.

[0012] According to one aspect of the invention, the electric heating wire is in the form of a continuous S-shaped bend and is attached to the inner wall panel.

[0013] According to one aspect of the present invention, an electric heating plate is provided on the upper surface of the base plate, the electric heating plate being used to support the bottom valve.

[0014] The present invention also provides a bottom discharge box structure for a tank container. The tank container has a discharge port at the bottom of the tank body, and a bottom valve is provided at the discharge port. The bottom discharge box structure is correspondingly located at the bottom valve. The bottom discharge box structure includes: a box body, which is hollow inside to accommodate the bottom valve; the box body has a forward opening and a rear wall facing the tank body; a plurality of support members; the plurality of support members are welded to the outer wall of the tank body and arranged around the discharge port; the support members protrude from the outer wall, and the ends of the support members away from the outer wall have connecting holes for connecting to the box body.

[0015] According to one aspect of the invention, the support member includes a base plate attached to the outer wall of the tank, and a support plate extending from the base plate by bending; the connecting hole is formed on the support plate.

[0016] The present invention also provides a tank container, including a frame, a tank body installed inside the frame, a heating structure disposed on the tank body, and a bottom discharge box structure disposed on the bottom of the tank body end cap; the heating structure has an electric heating wire arranged on the outer wall of the end cap near the rear wall of the box body.

[0017] As can be seen from the above technical solution, the bottom discharge box structure of the tank container provided by the present invention has at least the following advantages and positive effects:

[0018] The rear wall of the container has an opening. During use, a sealing plate enters the interior of the container through the opening and is removably placed over it. This provides a relatively enclosed space for the bottom valve, protecting it during tank transport. When a heating structure needs to be installed, the sealing plate is removed, exposing the opening. This opening eliminates obstructions between the container and the tank wall, removing dead angles in traditional wiring and allowing workers to easily install electric heating wires on the tank wall from the outside of the container. This ensures a high temperature in the bottom discharge area of ​​the tank, guaranteeing efficient unloading. Attached Figure Description

[0043] 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 variations in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations herein are for illustrative purposes only and not intended to limit the present invention.

[0044] This embodiment provides a tank container for storing and transporting materials such as liquid chemicals with high melting points. The tank container mainly includes a frame, a tank body horizontally installed inside the frame for storing materials, a heating structure on the tank body, and a bottom discharge box structure located at the bottom of the tank body head.

[0045] The tank body comprises a cylindrical shell and two end caps located at its front and rear ends. Heating structures are typically installed around the tank's perimeter and the front and rear end caps to heat the material inside to a specific temperature, ensuring cargo quality and facilitating unloading. Usually, a discharge port is located at the bottom of the rear end cap, with a flange welded to it, and a bottom valve is bolted to the flange. A bottom discharge box is positioned corresponding to the bottom valve, providing a relatively enclosed space for its protection during tank container transport.

[0046] The bottom discharge box structure of the present invention will be described in detail below through several embodiments.

[0047] The first embodiment of the bottom discharge box structure

[0048] Please refer to the above as well. Figure 1 and Figure 2 The bottom discharge box structure includes a box body 1 and a sealing plate 2.

[0049] The interior of box 1 is hollow, approximately rectangular, and is used to house the bottom valve 400. Figure 2 As shown, with Figure 2 With reference to the view direction, the lower end of the box body 1 is mounted on the bottom beam of the frame 200. The box body 1 has a forward-facing opening 101 and a rear wall 10 facing the rear end cap 301 of the tank body 300.

[0050] Specifically, such as Figure 1 As shown, the box body 1 includes two parallel side plates 11, a top plate 12 connected to the upper ends of the two side plates 11, a bottom plate 13 connected to the lower ends of the two side plates 11, a back plate 14 connected to the rear ends of the two side plates 11, and a cover plate 15 covering the opening 101 of the box body 1. The back plate 14 is the rear wall 10 of the box body 1, and the back plate 14 has an arc that matches the outer wall of the tank 300, and the back plate 14 is positioned as close as possible to the tank wall.

[0051] like Figure 2 As shown, there is a gap between the rear wall 10 and the tank wall, and an opening 102 is provided on the rear wall 10 (the opening 102 is marked by a dashed line, and its structure is described in the appendix below). Figure 4 (Specifically shown), the opening 102 communicates with the interior of the box 1. The opening 102 is opposite to the discharge port 302 of the tank 300. In other words, the opening 102 ensures that there are no obstructions between the box 1 and the tank wall, eliminating dead angles for wiring and facilitating wiring and subsequent maintenance.

[0052] Please refer to Figure 3 , Figure 3 This is a schematic diagram showing the concealed bottom valve 400 and the concealed bottom plate 13. The sealing plate 2 enters the interior of the housing 1 through the opening 101 and correspondingly and removably covers the opening 102. The sealing plate 2 has a through hole 201 for the bottom valve 400 to pass through only.

[0053] Please refer to Figure 4 and Figure 5 The opening 102 has a rectangular outline, and the rectangle is large in size, occupying almost most of the area of ​​the back plate 14. The opening 102 is large enough to provide sufficient working space for workers to lay the electric heating wires on the end cap 301 of the tank 300 from the outside.

[0054] In this embodiment, the sealing plate 2 is rectangular in shape to fit the opening 102. The sealing plate 2 is bolted to the rear wall 10 for easy disassembly. In other embodiments, the sealing plate 2 can also be detachable by snap-fit, hinge, or other means.

[0055] In normal working condition, the sealing plate 2 is fixed on the rear wall 10 of the box 1 to achieve relative sealing inside the box 1, so as to protect the bottom valve 400 from external interference.

[0056] When the heating structure needs to be installed, the operator can remove the sealing plate 2, exposing the opening 102, which then contacts the outer wall of the tank 300 at the rear wall 10 of the bottom box. This facilitates the installation of the electric heating wires 4 on the tank wall (bottom discharge area), ensuring a high temperature in the bottom discharge area and preventing any impact on unloading efficiency. In this way, the heating range of the heating structure can cover as much of the tank 300's perimeter as possible, eliminating localized low temperatures. It also facilitates future maintenance.

[0057] In summary, in this embodiment, the present invention proposes a detachable bottom box structure to achieve uniform wiring in the rear wall 10 area of ​​the bottom box, thereby improving cargo unloading efficiency and cargo quality.

[0058] Second embodiment of the bottom discharge box structure

[0059] Please refer to the above as well. Figures 6 to 9 The difference between this embodiment and the first embodiment is that the bottom box assembly is entirely detachable. This allows for the uniform wiring of the rear wall 10 area of ​​the bottom box before the insulation material is installed, followed by the overall installation of the bottom box. Since the bottom box is entirely detachable, it also facilitates future maintenance.

[0060] like Figure 6 As shown, the bottom discharge box structure also includes multiple support components 3.

[0061] Multiple support members 3 are welded onto the outer wall of the tank 300 and arranged around the discharge port 302.

[0062] The support member 3 protrudes from the outer wall, and a connection hole 33 for connecting the box body 1 is provided at the end of the support member 3 away from the outer wall. In this embodiment, the support member 3 and the box body 1 are connected by bolts for easy disassembly.

[0063] likeFigure 7 As shown, the support member 3 includes three upper support members 3a for connecting the upper end of the box body 1, and two sets of side support members 3b for connecting the left and right sides of the box body 1 respectively. The three upper support members 3a are approximately at the same height. Each set of side support members 3b includes at least two support members 3 arranged vertically at intervals to ensure connection strength.

[0064] In this embodiment, the support member 3 is approximately L-shaped.

[0065] The support member 3 includes a base plate 31 attached to the outer wall of the tank 300, and a support plate 32 extending from the base plate 31 by bending. The support plate 32 has a flat plate structure and is suspended. A connecting hole 33 is formed on the support plate 32.

[0066] In this embodiment, since the bottom box is detachable as a whole, there is no need to design an opening on the rear wall of the bottom box. Of course, in some embodiments, the above two embodiments can be extended simultaneously, that is, in addition to having the advantage of the detachable rear wall 10 sealing plate 2 of the box body 1 in the first embodiment, it also has the function of the bottom box assembly being detachable as a whole in this embodiment, so as to flexibly meet the arrangement requirements of the heating structure.

[0067] The third embodiment of the bottom discharge box structure

[0068] Please refer to the above as well. Figures 10 to 12 The difference between this embodiment and the two embodiments mentioned above is that an electric heating wire 4 is also arranged on the bottom box. The electric heating wire 4 transfers heat to the discharge point, thereby improving the unloading efficiency and quality of the goods.

[0069] The bottom box of the electric heating box is usually double-walled. For some special materials, electric heating wires 4 can be arranged on the inner wall of the bottom box, and then the outer wall of the bottom box can be installed by riveting.

[0070] Specifically, such as Figure 10 As shown, the two side panels 11 and the top panel 12 of the box body 1 are all double-layered structures, including an inner wall panel 111 and an outer wall panel 112 that are spaced apart from each other. An insulation layer is formed between the inner wall panel 111 and the outer wall panel 112.

[0071] The electric heating wire 4 is located inside the insulation layer and effectively transfers heat to the inside of the box 1 through the inner and outer wall panels to heat the entire box 1.

[0072] like Figure 11 As shown, the electric heating wire 4 is in the shape of a continuous S-shaped bend and is attached to the inner wall plate 111 of the side plate 11.

[0073] like Figure 12As shown, the electric heating wire 4 is in the shape of a continuous S-shaped bend and is attached to the inner wall plate 111 of the top plate 12 to maximize the heating range and ensure the heating effect.

[0074] Furthermore, please refer to the following: Figures 13 to 16 An electric heating plate 5 is provided on the upper surface of the base plate 13.

[0075] like Figure 14 As shown, the electric heating plate 5 is used to support the bottom valve 400 and heats the bottom valve 400 after being powered on, so as to further ensure good heating effect.

[0076] In this embodiment, the electric heating plate 5 is a rectangular plate structure, which is fixed to the base plate 13 by fasteners such as bolts.

[0077] The size of the electric heating plate 5 is appropriate considering the overall size of the bottom valve 400, and will not take up too much space at the bottom of the box 1. Furthermore, in this embodiment, the electric heating plate 5 is used instead of the electric heating wire 4 because the bottom plate 13 needs to be disassembled. Once the bottom plate 13 is removed, the electric heating plate 5 will be removed along with the bottom plate 13, while the electric heating wire 4 would interfere with the disassembly due to its more complicated wiring.

[0078] Please refer to Figure 17 In this embodiment, an opening 102 is provided on the rear wall 10 of the box body 1 (as in the first embodiment), and a removable sealing plate 2 is provided, which can realize uniform wiring in the area of ​​the rear wall 10 of the bottom box, increase the insulation material, and facilitate later maintenance.

[0079] In this embodiment, the inner wall panels 111 of the two side panels 11, the inner wall panel 111 of the top panel 12, and the rear wall 10 are all mounted on the end cap. The rear wall 10 has an opening 102 and provides a removable sealing plate 2 for easy wiring and maintenance of the electric heating wires; the bottom box has electric heating wires arranged on the aforementioned inner wall panels 111 to achieve heating of the bottom box. The aforementioned outer wall panel 112 is bolted to the end cap through a support member 3, and the outer wall panel 112 is riveted to the inner wall panel 111, so that only the outer wall of the bottom box is removable.

[0080] Of course, in other embodiments, the above three embodiments can be extended. That is, in addition to having the advantage of the removable rear wall sealing plate 2 of the box body 1 in the first embodiment, it also has the function of the overall removable bottom box assembly in the second embodiment, flexibly meeting the arrangement requirements of the heating structure. At the same time, the box body 1 has a double-layer structure with an insulation layer. The box body 1 is heated by the electric heating wire 4, which improves the unloading efficiency and quality of goods. Furthermore, an electric heating plate 5 is provided on the upper surface of the bottom plate 13, which focuses on heating the bottom valve 400 to further ensure good heating effect.

[0081] Although the invention has been described with reference to several typical embodiments, it should be understood that the terminology used is illustrative and exemplary, and not restrictive. Since the invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
