Technical Field

[0001] The present invention relates to the technical field of tank containers, and particularly relates to a tank container. Background Art

[0002] Tank containers can not only make the transportation of dangerous goods safer and more efficient, but also reduce the cost during transportation. At the same time, tank containers can also achieve multimodal transport (railway, sea, road) among countries around the world, making the transportation of goods faster. Therefore, the application of tank containers is becoming more and more extensive, and the number is increasing at a rate of tens of thousands per year.

[0003] In the prior art, in order to heat the medium filled inside a tank container, a heating system for circulating a heat transfer medium needs to be provided on the tank container. Since the heating efficiency of a steam heating system is relatively higher than that of other forms of heating systems, more than 95% of the existing tank containers are equipped with a steam heating system.

[0004] The current steam heating system generally realizes heating only through one heating pipe. In order to improve the heating efficiency of the steam heating system, usually the heating pipe is bent in multiple ways to increase the contact area between the pipe and the tank container, thereby expanding the heating area. However, it is found after actual application that the flow rate of steam introduced into the heating pipe is constant. When the number of bends of the heating pipe reaches a certain degree, the heating efficiency of the heating system will no longer increase, thus unable to meet the heating requirements of the tank container. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem that it is difficult to improve the heating efficiency of the heating system and unable to meet the heating requirements of the tank container in the prior art.

The heating system includes a plurality of heating pipes, and the plurality of heating pipes are arranged at intervals along the circumferential direction of the tank body. Each heating pipe is arranged along the length direction of the tank body. The plurality of heating pipes are connected through connecting pipes to form a hollow medium channel. The heating system further includes at least two heating medium inlets and at least one heating medium outlet that are connected to the medium channel.

[0007] Preferably, a plurality of partition plates are arranged at intervals inside the medium channel. The circumferential sides of the partition plates are attached to the inner walls of the heating pipes or connecting pipes and are fixedly connected to the inner walls of the heating pipes or connecting pipes. Each partition plate is provided with through holes for the heat transfer medium to pass through.

[0008] Preferably, the pore diameters of the through holes on each partition plate are not completely the same.

[0009] Preferably, the medium channels are divided into a plurality of non - communicating channel groups, and each of the channel groups has at least one heating medium inlet and at least one heating medium outlet.

[0010] Preferably, one set of the channel groups is provided above and below the horizontal mid - plane of the tank body respectively, and each of the channel groups has one heating medium inlet and one heating medium outlet.

[0011] Preferably, the heating tubes are connected into a mutually - communicating channel group through the connecting pipes.

[0012] Preferably, the channel group has two heating medium inlets and one heating medium outlet.

[0013] Preferably, the cross - section of the heating tube and / or the connecting pipe is arc - shaped or groove - shaped, and the open end of the heating tube and / or the connecting pipe faces the tank body and is fixedly connected to the inner surface or the outer surface of the tank body.

[0014] Preferably, the cross - section of the heating tube and / or the connecting pipe is circular or a closed polygon, and the outer wall of the heating tube and / or the connecting pipe is fixedly connected to the inner surface or the outer surface of the tank body.

[0017] The heating system of the present invention can introduce a heat - transfer medium through the heating medium inlet, and the heat - transfer medium circulates in the medium channels, thereby heating the tank body. During the actual heating process, multiple unit volumes of the heat - transfer medium can be introduced through multiple heating medium inlets of the heating system. Under the condition that the diameters of the heating tubes are the same, compared with the existing heating system, the flow rate of the heat - transfer medium in the medium channels of the heating system of the present invention will be greatly increased, and thus the heating efficiency of the tank body will be effectively improved.

[0023] Typical implementation manners reflecting 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 implementation manners, all of which do not depart from the scope of the present invention, and the descriptions and illustrations therein are essentially for illustrative purposes rather than for limiting the present invention.

[0024] In order 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.

[0025] This application provides a tank container, which includes a tank body. The tank container further includes a heating system, and the heating system is connected to the tank body. The heating system can heat the medium inside the tank body, thereby ensuring the smooth discharging of the tank container. The structure of the heating system of this application will be described in detail below with reference to multiple embodiments.

[0026] Embodiment 1 of the heating system

[0027] Referring to Figure 1 , the heating system 1 of this embodiment includes multiple heating tubes 11. The multiple heating tubes 11 are arranged at intervals along the circumferential direction of the tank body 2, and each heating tube 11 is arranged along the length direction of the tank body 2. Such an arrangement can ensure heating the tank body 2 in both the circumferential direction and the axial direction of the tank body 2.

[0028] Furthermore, in this embodiment, the multiple heating tubes 11 are connected through connecting pipes 12 to form a hollow medium channel 13. The heating system 1 further includes at least two heating medium inlets 14 and one heating medium outlet 15 that are connected to the medium channel 13.

[0029] For the heating system 1 of this embodiment, a heat transfer medium can be introduced through the heating medium inlet 14, and the heat transfer medium circulates in the medium channel 13 to heat the tank body 2. During the actual heating process, multiple unit volumes of the heat transfer medium can be introduced through the multiple heating medium inlets 14 of the heating system 1 of this embodiment. Under the condition that the diameters of the heating tubes 11 are the same, compared with the existing heating system 1, the flow rate of the heat transfer medium in the medium channel 13 of this embodiment will be greatly increased, and thus the heating efficiency of the tank body 2 will also be effectively improved.

[0030] Multiple partitions 16 are arranged at intervals inside the medium channel 13 of this embodiment, and the shape of the partition 16 is adapted to the cross-sectional shape of the medium channel 13. AsFigure 2 As shown, taking the partition 16 in the connecting pipe 12 as an example, the cross-section of the connecting pipe 12 in this embodiment is in the shape of a square groove, and its medium channel 13 is square. Therefore, the partition 16 is also correspondingly square. Further, the periphery of the partition 16 is attached to the inner wall of the heating pipe 11 or the connecting pipe 12 and is fixedly connected to the inner walls of the heating pipe 11 and the connecting pipe 12. Each partition 16 is provided with a through hole 161 for the heat transfer medium to pass through.

[0031] Preferably, in this embodiment, the apertures of the through holes 161 on each partition 16 are not completely the same, so as to effectively control the flow rate of the heat transfer medium at different segments in the medium channel 13, make the heat transfer medium flow more evenly in each heating pipe 11, and further improve the heat exchange efficiency.

[0032] Further, the medium channel 13 in this embodiment can be divided into a plurality of non-connected channel groups 10, and each channel group 10 has at least two heating medium inlets 14 and at least one heating medium outlet 15. Each channel group 10 can independently heat the tank body 2. When each channel group 10 has a plurality of heating medium inlets 14, the heat transfer medium can be introduced into each heating medium inlet 14 in the channel group 10 at the same time to increase the flow rate of the heat transfer medium in each channel group 10, thereby improving the overall heating efficiency of the tank body 2.

[0033] As Figure 1 shown, in this embodiment, a set of channel groups 10 are respectively provided above and below the horizontal middle plane of the tank body 2, and each channel group 10 has a heating medium inlet 14 and a heating medium outlet 15. Specifically, in this embodiment, eight heating pipes 11 are respectively provided above and below the horizontal middle plane of the tank body 2, and the eight heating pipes 11 are connected through the connecting pipe 12 to form a set of channel groups 10.

[0034] The upper half tank body and the lower half tank body of the horizontal middle plane of the tank body 2 can be heated respectively through the two sets of channel groups 10, that is, the tank body 2 can be heated by using two units of heat transfer medium at the same time. Compared with the traditional heat transfer system that can only introduce one unit of heat transfer medium for heating, the heating system 1 in this embodiment has higher heating efficiency.

[0035] When the heat transfer medium is steam, since the steam will be converted into water after condensation, only part of the high-quality energy of each unit of steam can be used for heating. For the traditional heating system 1, only the front part of the multi-channel curved pipeline can effectively heat the tank body 2. For each channel group 10 in this embodiment, by dividing the heating pipe 11 into two channel groups 10 and introducing steam into each channel group 10, each heating pipe 11 in each channel group 10 can utilize the high-quality part of the unit volume of steam, so as to more effectively heat the tank body 2.

[0036] The heating pipe 11 and the connecting pipe 12 of this embodiment can be arranged on the outer surface of the tank body 2 or fixed to the inner surface of the tank body 2.

[0037] Refer to Figure 3 , the cross-section of the heating pipe 11 of this embodiment is arc-shaped, and the open end of the heating pipe 11 faces the tank body 2 and is fixedly connected to the inner surface or the outer surface of the tank body 2. In addition, the cross-section of the heating pipe 11 can also be a groove shape, a circular shape or a closed polygon. When the cross-section of the heating pipe 11 is circular or a closed polygon, the outer wall of the heating pipe 11 is fixedly connected to the inner surface or the outer surface of the tank body 2.

[0038] For the connecting pipe 12, in addition to the square groove shape described in this embodiment, its cross-section can also be arc-shaped, circular and closed polygons. The connection mode of the connecting pipe 12 to the tank body 2 is the same as that of the heating pipe 11, and will not be elaborated here.

[0039] In addition, in this embodiment, both the heating medium inlet 14 and the heating medium outlet 15 are arranged at one end in the length direction of the tank body 2 and close to the bottom of the tank body 2, which is not only convenient for the operator to introduce steam into the medium channel 13, but also conducive to effectively discharging the condensed water in the heating system 1.

[0040] Heating system 1, Embodiment 2.

[0041] The heating system 1 of this embodiment is substantially the same as that of Embodiment 1, and the main difference lies in that: each heating pipe 11 is connected into a mutually connected channel group 10 through a connecting pipe 12.

[0042] Further, refer to Figure 4 , in this embodiment, the channel group 10 has two heating medium inlets 14 and one heating medium outlet 15. Heat transfer medium can be introduced into the medium channel 13 simultaneously through the two heating medium inlets 14, so that the flow rate of the heat transfer medium in the heating system 1 is doubled, thereby effectively improving the heating efficiency.

[0043] In summary, the heating system provided by this application effectively improves the heating efficiency of the tank body by increasing the flow rate of the heat transfer medium in the medium channel. The pipeline layout of this heating system is simple and reasonable, and is easy to maintain subsequently. At the same time, the manufacturing cost of this heating system is low, and it can be widely applied in the heating field of tank containers.

[0044] While the invention has been described with reference to several exemplary embodiments, it should be understood that the terms used are illustrative and exemplary, rather than 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-described embodiments are not limited to any of the foregoing details, but should be construed broadly within the spirit and scope defined by the appended claims, and accordingly all variations and modifications that fall within the scope of the claims or their equivalents should be covered by the appended claims.
