Referring to fig. 3, fig. 3 shows a specific structure of a tank container according to the present embodiment.

The tank 200 includes a cylinder 20 and two end sockets respectively disposed at two ends of the cylinder 20.

Referring to the view direction of fig. 3, the head disposed at the left end of the cylinder 20 is defined as a front head 21, and the head disposed at the right end of the cylinder 20 is defined as a rear head 22. The following "front, rear, upper and lower" directions are used as a standard, and unless otherwise noted, the directions of the following examples are all based on the directions and do not vary.

The heating structure 100 includes a plurality of heating jackets 1 and a connecting line 3. Wherein a plurality of heating jackets 1 are arranged at intervals in the longitudinal direction of the can body 200. Each heating jacket 1 extends along the circumferential direction of the can 200 to cover the can 200. The heating jacket 1 comprises two plate members 11 which are oppositely overlapped and welded together, and the two plate members 11 are double-faced swelled by pressure to form a hollow sandwich 12. The connecting pipeline 3 is used for the inflow and outflow of the heating medium; the connecting pipes 3 extend along the longitudinal direction of the tank 200 and are respectively connected and communicated with the interlayers 12 of the heating jackets 1. Therefore, the respective interlayers 12 are communicated with each other through the connecting pipe, so that the heating medium can flow through the interlayers 12 simultaneously in the circumferential direction and the longitudinal direction of the tank 200 to heat the tank 200 in a large area.

The tank container also includes a plurality of sets of straps 5. Each set of the bands 5 is disposed corresponding to each heating jacket 1, and the bands 5 are wound around the outer surface of the heating jacket 1 in the circumferential direction of the tank 200, thereby fastening the heating jacket 1 to the tank 200. The binding mode replaces the traditional welding and fixing mode, so that the installation, the disassembly and the maintenance of the heating structure 100 are very convenient, and the practicability is high.

Compared with the conventional heating tube, the plate 11 of the heating jacket 1 extends along the circumferential direction of the can body 200, the length of the plate 11 is longer, and the plate 11 is not limited by the width, so that the surface area of the interlayer 12 is larger, the heating area is larger, and the bottom of the can body 200 can be easily and completely covered. In addition, due to the existence of the interlayer 12, the contact between the heating medium and the outer wall of the tank body 200 is avoided, the problem of corrosion of the heating medium to the tank wall is solved, and the service life of the tank box is prolonged.

In this embodiment, the heating jacket 1 is mainly disposed on the cylinder 20 and wraps the bottom of the cylinder 20, so that the material deposited on the bottom of the tank can be effectively heated. In other embodiments, the heating jacket 1 may also be provided at the head.

Referring to fig. 4, the heating jacket 1 is a honeycomb jacket, and two plates 11 are welded at multiple points and expanded by pressure to form a sandwich structure with interconnected internal voids.

The honeycomb jacket is a high-efficiency heat transfer structure and is characterized by that it has a sealed space, in which the heat-exchange medium can be introduced for heating or cooling material to maintain the temperature of material in a predefined range. The honeycomb jacket is typically laser welded and pressure bulging is critical to its formation.

The manufacturing process of the honeycomb jacket comprises the following steps: generally, two thin steel plates with smaller thickness and consistent size are closely attached together, the peripheries of the two thin steel plates are welded together to form edge sealing welding, and the sealing property is ensured for two-circle edge sealing welding; then welding points arranged along the regular triangle or the square by using high-energy laser beams, wherein the welded points are honeycomb points; then, the plate 11 is rolled and bent into an arc shape, and then is expanded by pressure to form a jacket structure with a honeycomb-shaped appearance. The honeycomb jacket has the advantages of large heat transfer coefficient and good heat exchange effect because the distribution of the honeycomb points has a disturbance effect on the fluid.

As shown in fig. 4, the outer surface of the heating jacket 1 is recessed by welding to form a plurality of grooves 101. When the heating jacket 1 is wound on the tank body 200, the partial surface of the heating jacket 1 except the groove 101 is tightly attached to the outer wall of the tank body 200 as much as possible, so that the heating area is increased; with a gap between the groove 101 and the tank wall.

To this end, the heating structure 100 further comprises a thermally conductive material 7. The heat conductive material 7 is filled at the groove 101 and is in direct contact with the tank wall. Furthermore, the heat conductive material 7 is also sandwiched between the heating jacket 1 and the tank wall. The heat conduction material 7 can be heat conduction daub or heat conduction silicone grease and the like, can not only effectively transmit heat to the tank body 200, but also can be filled in the groove 101 well without gaps, so that the heating effect is further improved.

Referring to fig. 5 and 6, after the heating jacket 1 is unfolded, the welding seam 13 of the heating jacket 1 may be circular or elongated. In other embodiments, the shape is not limited to the above.

Referring to fig. 7 and 8 together, the heating jacket 1 includes a first jacket 14 and a second jacket 15 which are symmetrical along the longitudinal central axis of the can 200; the first jacket 14 and the second jacket 15 each have an arc-shaped profile to fit on the peripheral wall of the can 200. Preferably, the central angle of each jacket is as close to 90 degrees as possible, allowing for effective coverage of the bottom of the can 200.

The connecting line 3 is divided into a line inlet side and a line outlet side.

Wherein the line inlet side comprises an inlet main pipe 30, a first inlet pipe 31, a second inlet pipe 32 and a plurality of branch pipes 33, and the heating medium can be fed to each heating jacket 1 by connecting them to each other.

The inlet main pipe 30 is substantially U-shaped, and is a first-stage pipe into which the heating medium flows. The inlet main pipe 30 is arranged obliquely upward to be close to the lower side surface of the spherical end socket at the rear end of the tank body 200, so as to be positioned inside the frame.

The first inlet pipe 31 and the second inlet pipe 32 are respectively connected to two bent transverse ends of the inlet main pipe 30, and each inlet pipe extends from back to front along the longitudinal direction of the tank 200, that is, a rear end pipe orifice of each inlet pipe is an inlet 301 for the heating medium to flow in.

As shown in fig. 8, the first inlet pipe 31 and the second inlet pipe 32 are arranged above the horizontal middle axial surface of the tank and are respectively provided corresponding to the first jacket 14 and the second jacket 15. A plurality of branch pipes 33 are provided at regular intervals on the first inlet pipe 31. The first inlet pipe 31 is connected to the upper end of the first jacket 14 through a branch pipe 33 and communicates with the sandwich 12 thereof. Similarly, a plurality of branch pipes 33 are provided at regular intervals in the second inlet pipe 32, and are connected to and communicated with the upper end of the second jacket 15 through the branch pipes 33.

As shown in fig. 7, the outlet side of the pipeline is provided at the bottom of the tank 200, and includes an outlet pipe 35a and a plurality of jacket outlet pipes 34.

The number of the plurality of jacket outlet pipes 34 corresponds to the number of the respective heating jackets 1. The interlayer 12 of the first jacket 14 is communicated with the interlayer 12 of the second jacket 15 through a jacket outlet pipe 34. The jacket outlet pipe 34 is arranged extending along the circumferential direction of the can 200.

The outlet pipe 35a extends longitudinally from back to front, is perpendicular to the plurality of jacket outlet pipes 34, and communicates with the center of each jacket outlet pipe 34. The rear end nozzle of the outlet pipe 35a is an outlet 302 through which the heating medium flows. Equivalently, the outlet 302 is located on the same side of the tank as the inlet 301. So, the homonymy sets up and can make things convenient for the staff to operate to and operations such as maintenance.

During heating, the heating medium enters from the inlet 301 of the inlet main pipe 30 as indicated by an arrow, is branched by the inlet main pipe 30, reaches the first inlet pipe 31 and the second inlet pipe 32, and flows into the heating jacket 1 through the branch pipe 33. The heating medium transfers heat to the tank body 200 in the jacket to melt the materials in the tank, then the materials are converged and flow into the outlet pipe 35a through the jacket outlet pipe 34, and finally the materials flow through the outlet 302 and are discharged outwards, so that circulation is realized.

In this embodiment, the outlet side of the line is disposed at the bottom of the jacket to facilitate the discharge of the heating medium and condensed water from the jacket.

In other embodiments, the jacket outlet pipe 34 need not be provided, and the intermediate layers in the two jackets need not be connected, but a plurality of first jackets 14 may be used to simultaneously communicate with one outlet pipe, a plurality of second jackets 15 may be used to simultaneously communicate with the other outlet pipe, and the two outlet pipe connections may be brought together and finally connected to the outlet pipe 35 a.

In summary, the tank container provided by the utility model at least has the following advantages and positive effects:

the heating structure 100 adopts a plurality of heating jackets 1 arranged at intervals along the longitudinal direction of the can body 200. The heating jacket 1 extends in the circumferential direction of the can 200 to cover the can 200. Specifically, the heating jacket 1 comprises two plate members 11 which are overlapped with each other and welded together, and the two plate members 11 are double-faced swollen by pressure to form a hollow sandwich 12. The interlayers 12 are communicated with each other through a connecting pipe, so that the heating medium can flow through the interlayers 12 along the circumferential direction and the longitudinal direction of the tank body 200 at the same time, and the tank body 200 is heated in a large area.

Compared with the conventional heating tube, the plate 11 of the heating jacket 1 extends along the circumferential direction of the can body 200, which is equivalent to the length of the plate 11 is longer, and the plate 11 is not limited by the width, so that the surface area of the interlayer 12 is larger, and the heating area covered on the can body 200 can be easily increased to achieve the expected good heating effect. In addition, due to the existence of the interlayer 12, the contact between the heating medium and the outer wall of the tank body 200 is avoided, the problem of corrosion of the heating medium to the tank wall is solved, and the service life of the tank box is prolonged.

Concrete second embodiment of tank container

Referring to fig. 9 and 10 together, the difference between the present embodiment and the first embodiment is: the outlet pipes are of different construction.

The outlet pipe 35b of this embodiment is similar to a long U-shaped pipe and includes a first outlet pipe 351 and a second outlet pipe 352 which are bent to meet and are spaced apart in parallel. Both outlet pipes extend longitudinally from back to front.

Wherein the first outlet pipe 351 is centrally positioned at the bottom of the tank body, and the first outlet pipe 351 is vertically connected with each jacket outlet pipe 34 to communicate all the interlayers of the first jacket 14 and the second jacket 15. The rear end of the first outlet pipe 351 is closed.

The second outlet pipe 352 is spaced apart from and parallel to the first outlet pipe 351. The front end of second outlet pipe 352 is bent and connected to the front end of first outlet pipe 351, and the rear end nozzle of second outlet pipe 352 is outlet 302 through which the heating medium flows out.

In the first embodiment, since the inlet 301 and the outlet 302 of the heating structure 100 are both located at the rear end of the tank, that is, the inlet 301 and the outlet 302 are located on the same side of the tank body, according to conventional thinking, the connecting pipeline 3 is often easily designed into the structure as shown in fig. 7 of the first embodiment, however, when in use, the medium in the heating jacket 1 closer to the rear end flows faster, while the heating jacket 1 at the front end cannot heat due to short circuit of steam, and the heating effect is not good.

Therefore, this embodiment is modified in the U-shape of outlet pipe 35b such that the heating medium from each heating jacket 1 first converges at the front end of first outlet pipe 351 and then flows out from rear outlet port 302 through second outlet pipe 352; in other words, the total path of the heating medium flowing through each heating jacket 1 from the inlet 301 to the outlet 302 is equal, so that the condition of uneven heating caused by steam short circuit is avoided.

Concrete third embodiment of tank container

The present embodiment is different from the second embodiment in that: the outlet pipes are of different construction.

The outlet tubes are divided into spaced parallel first outlet tube 351, second outlet tube 352 and third outlet tube (not shown). The three outlet tubes each extend longitudinally from rear to front.

The first outlet pipe 351 is provided near the bottom of the first jacket 14 and is connected to and communicated with all the interlayers of the first jacket 14. The rear end of first outlet pipe 351 is closed, and the front end of first outlet pipe 351 is an outlet for the heating medium of each first jacket 14.

The second outlet pipe 352 functions in the same manner as the first outlet pipe 351. The second outlet pipe 352 is provided near the bottom of the second jacket 15 and is connected to and communicates with all the layers of the second jacket 15. The front end of second outlet pipe 351 is an outlet for the heating medium of each second jacket 15, and the front end of second outlet pipe 351 and the front end of first outlet pipe 351 are connected together in a bent manner to form a collective end.

Thus, the first jacket 14 and the second jacket 15 in this embodiment are not directly connected together, but are in a parallel relationship relatively independently, due to the separate arrangement of the two outlet pipes.

The front end of the third outlet pipe is connected and communicated with the collecting end, so that the heating mediums flowing out through the first jacket 14 and the second jacket 15 are combined together; the rear end of the third outlet pipe is an outlet 302 from which the collected heating medium flows out. That is, the outlet 302 is located on the same side of the tank as the inlet 301.

The principle of the design of the heating circuit of this embodiment is the same as that of the equal path heating circuit of the second embodiment. That is, the total path of the heating medium flowing through each heating jacket 1 from the inlet 301 to the outlet 302 is equal, so that the condition of uneven heating caused by steam short circuit is avoided.

Concrete fourth embodiment of tank container

Compared with the three embodiments, the present embodiment is different in that: the outlet 302 and the inlet 301 are respectively positioned on two sides of the tank body in the axial direction.

Specifically, the outlet 302 may be disposed at a front end of the tank, while the inlet 301 is disposed opposite a rear end of the tank. On the basis, the design of the outlet 302 and the inlet 301 still follows the principle of an equal-path heating pipeline, so that the phenomenon of steam short circuit is avoided, and meanwhile, the arrangement of the opposite sides of the outlet 302 and the inlet 301 can meet the requirement that the heating medium can be fully circulated and heated in the jacket.

While the present invention has been described with reference to several exemplary embodiments, it is understood that the terminology used is intended to be in the nature of words of description and illustration, rather than of limitation. As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
