As shown in fig. 1 and 2, the present embodiment provides a tank container including a tank body 10, a mounting frame 20, a mounting ring assembly 30, and an insulation layer. Wherein, the tank body 10 is positioned inside the mounting frame 20; the mounting ring assembly 30 is arranged between the tank body 10 and the mounting frame 20, and the mounting ring assembly 30 is sleeved on the periphery of the tank body 10; an insulation layer is disposed between the mounting ring assembly 30 and the can body 10.

In this embodiment, the thermal insulation layer is disposed between the mounting ring assembly 30 and the can body 10, so as to prevent the mounting ring assembly 30 from directly contacting with the can body 10, and further to block the heat conduction between the mounting ring assembly 30 and the can body 10, so as to prevent the heat of the can body 10 from being transferred to the mounting ring assembly 30 and the mounting frame 20, thereby reducing the heat loss of the can body 10.

The tank container in the prior art generally adopts the following structure: the tank body is connected with the mounting frame through the supporting beam, and the supporting beam bears vertical, longitudinal and transverse loads, so that the transportation working condition requirements can be met. Because the support beam is connected with the mounting frame in a welding way and the support beam is connected with the tank body in a welding way, the temperature of the medium in the tank body is directly transferred to the mounting frame through the support beam, and the heat loss is serious.

The technical proposal of the embodiment separates the installation ring assembly 30 from the tank body 10 by arranging the heat insulation layer between the installation ring assembly 30 and the tank body 10, so that the installation ring assembly 30 is not in direct contact with the tank body 10. Because the thermal-insulated effectual of insulating layer, jar body 10 and insulating layer direct contact have blocked thermal transmission, have reduced calorific loss, avoid the tank body secondary heating after tank container short distance transportation, have reduced the cost loss of secondary heating.

As shown in fig. 3 and 4, in the present embodiment, the mounting ring assembly 30 includes a mounting ring body 31 and a first thermal shield 32. The installation ring body 31 is sleeved on the periphery of the tank body 10, the outer wall surface of the installation ring body 31 is connected with the installation frame 20, the installation ring body 31 is provided with an installation groove, and the opening of the installation groove faces the tank body 10; a first insulation 32 is provided in the mounting groove, the first insulation 32 having a mounting surface adapted to the outer periphery of the can body 10.

Specifically, the first heat insulation member 32 is disposed in the mounting groove and adapted to the outer periphery of the tank body 10, so as to be attached to the outer surface of the tank body 10, thereby supporting the tank body 10, and preventing the tank body 10 from directly contacting the mounting ring body 31, thereby preventing heat conduction between the tank body 10 and the mounting ring body 31.

Preferably, the first thermal shield 32 is made of wood.

Timber has good compressive strength and thermal-insulated effect, can support the vertical load of jar body 10 to coefficient of thermal conductivity is low, effectively prevents jar heat conduction of body 10 to the collar body 31 on, and low price, and the cost is lower.

Further, the heat insulation ring 341 may be an integral structure, or may be two structures stacked together, and when the heat insulation ring 341 is two structures stacked together, the central pin 342 also plays a role in shearing resistance between the two heat insulation rings, and the length dimension of the central pin 342 is greater than the axial dimension of the two heat insulation rings by one. The specific number of settings and the size of the heat insulating ring 341 are determined in accordance with the operation space at the time of assembly.

In order to avoid the influence on the structural strength of the tank body 10 due to the installation of the installation groove, when the seat body 11 is installed on the tank body 10, the reinforcing plate 12 is arranged between the seat body 11 and the tank body 10, and the reinforcing plate 12 is welded to the tank body 10, so as to increase the structural strength between the tank body 10 and the seat body 11 and prevent the medium in the tank body 10 from leaking.

As shown in fig. 1 and 2, in the present embodiment, the mounting ring assembly 30 includes a plurality of positioning sleeves 33, and the plurality of positioning sleeves 33 are arranged at intervals in the circumferential direction of the mounting ring body 31.

Through the arrangement, the positioning sleeves 33 can position the tank body 10 in the circumferential direction of the tank body 10, so that the tank body 10 is prevented from rotating due to self inertia or vibration in the transportation process.

As shown in fig. 1 and 2, in the present embodiment, the mounting ring assembly 30 is provided in plurality, and the plurality of mounting ring assemblies 30 are arranged at intervals in the axial direction of the can body 10.
