Problems solved by technology

However, the tank cavity of a traditional vacuum tank is difficult to withstand high pressure. This is because when there is a high pressure inside the vacuum tank, the inner tank is easy to expand and deform outwards, so that the inner tank and the outer shell are close to conduct heat and reduce the thermal insulation performance of the tank.
In addition, when the fixed object is stored in the tank cavity of the traditional vacuum tank, the inner tank is easily deformed or even damaged by the internal fixed object.
Although increasing the thickness of the liner can solve the above-mentioned problems, it brings various problems such as more materials, high production cost, poor roundness of the liner, heavy and difficult to move the tank, etc.

Embodiment 1

[0057] Figure 1 to Figure 5 A specific embodiment of the vacuum insulation tank of the present application is shown, which includes some traditional vacuum insulation tanks: an outer shell 1, an inner container 2 arranged in the outer shell, and a vacuum barrier formed between the outer shell and the inner container. Hot chamber3. A tank mouth 6 with a small diameter is arranged on the top of the vacuum insulation tank, and the shell 1 and the inner tank 2 are made of stainless steel.

[0058]If the above-mentioned vacuum insulation tank is a large volume water tank, the size of the shell 1 is very large. Then, under the action of external force (not to mention the negative pressure environment inside the outer shell 1), the outer shell 1 is easily dented and deformed inward, which will cause the outer shell 1 and the inner tank 2 to be in close contact with each other in a large area, so that the heat can be quickly transferred between the inner tank and the outer shell. ,...

Embodiment 2

[0077] Figure 6 to Figure 8 It shows the second specific embodiment of the vacuum insulation tank of the present application, which has basically the same structure as the first embodiment, with two main differences:

[0078] In this embodiment, the shell wall of the shell 1 is extruded with a first extrusion protruding ring 101 arranged coaxially with the rotator shell and protruding radially outward. The first extruded convex ring 101 is formed by mechanically extruding the shell 1. After the first extruded convex ring 101 is extruded and processed to produce the aforementioned first extruded convex ring 101, the first extruded convex ring 101 will naturally An extrusion ring groove is formed on the inner periphery, and the support ring 8 is embedded in the foregoing extrusion ring groove, so that the position of the support ring 8 is limited by the extrusion ring groove.

[0079] In this embodiment, a second extruding convex ring 201 coaxially arranged with the outer casi...

Embodiment 3

[0082] Figure 9 Shown is the third specific embodiment of the vacuum insulation tank of the present application, which has basically the same structure as the first embodiment, the main difference being:

[0083] In this embodiment, the support ring 8 is integrally provided with an annular support ring reinforcing rib 801 located on the inner circumference of the support ring and arranged coaxially with the support ring, as shown in Figure 10 and Figure 11 . Compared with the support ring in the first embodiment, the support ring 8 with the support rib 801 on the inner circumference has a higher pressure bearing capacity.

[0084] In this embodiment, the above-mentioned support ring rib 801 is an extruded protrusion formed by extruding the support ring 8 , and an extruded ring groove 802 is formed on the outer periphery of the extruded protrusion. In order to facilitate fixing the support ring 8 in the housing 1, a radially inwardly convex extruded convex ring can be ext...

Abstract

The invention relates to a vacuum heat preservation tank. The vacuum heat preservation tank comprises a shell, an inner container arranged in the shell and a vacuum heat insulation cavity formed between the shell and the inner container, wherein a hoop ring fixedly arranged on the periphery of the inner container in a sleeving mode is arranged in the vacuum heat insulation cavity. The vacuum heat preservation tank can bear high pressure and preserve heat for a long time.

Description

technical field [0001] The present application relates to a tank, especially a vacuum insulation tank. Background technique [0002] The vacuum tank is mainly composed of an outer shell, an inner tank, and a vacuum insulation cavity formed between the outer shell and the inner tank, which has excellent heat insulation performance. However, the tank cavity of a traditional vacuum tank is difficult to withstand high pressure. This is because when there is high pressure inside the vacuum tank, the inner tank is easy to expand and deform outwards, so that the inner tank and the outer shell are close to conduct heat and reduce the thermal insulation performance of the tank. In addition, when storing fixtures in the tank cavity of traditional vacuum tanks, the inner tank is easily deformed or even damaged by the internal fixtures. Although increasing the thickness of the liner can solve the aforementioned problems, it brings various problems such as more materials used, high prod...
