[0025] Exemplary embodiments of the utility model will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the utility model are shown in the drawings, it should be understood that the utility model can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided so that the utility model can be more thoroughly understood and the scope of the utility model can be completely conveyed to those skilled in the art.

[0026] As Figure 1As shown, an embodiment of this utility model provides a heat-insulating tank with a filling layer, comprising:

[0027] Outer tank 1;

[0028] An inner tank 2 extends into the interior of the outer tank 1 and is fixedly connected to the outer tank 1, forming a cavity 3 between the inner tank 2 and the outer tank 1;

[0029] Thermal insulation material 4 is filled in the cavity 3;

[0030] A filling port 5 is provided at the top of the outer tank body 1;

[0031] The discharge port 6 is located at the bottom of the outer tank 1.

[0032] In this embodiment, the outer tank 1 is cylindrical and made of stainless steel, giving it high strength and corrosion resistance. The outer tank 1 is hollow inside with an opening at the top. The bottom and middle of the inner tank 2 extend into the outer tank 1 through the opening. The outline of the opening of the outer tank 1, i.e., its cross-section, is the same as or slightly larger than the cross-section of the inner tank 2, ensuring that the opening of the inner tank 2 fits snugly against its outer surface when inserted into the outer tank 1. When the inner tank 1 extends to a suitable length, the opening of the outer tank 1 can be welded to the outer surface of the inner tank 2. The outer tank 1 and the inner tank 2 are fixed together and sealed, forming an integral structure. At the same time, a cavity 3 is formed between the outer tank 1 and the inner tank 2. The top of the outer tank 1 is provided with a filling port 5, through which the insulation material 4 can be poured into the cavity 3. The insulation material 4 is a poor conductor of heat, which can slow down the rate at which the temperature of the material stored in the inner tank 2 decreases, thereby achieving the insulation effect of the material. The bottom of the outer tank 1 is also provided with a discharge port 6, through which the insulation material 4 can be poured out, thereby realizing the periodic replacement of the insulation material and ensuring that the insulation tank is always in optimal working condition.

[0033] The present invention improves the heat preservation effect of sensitive materials and reduces storage and transportation costs.

[0034] In an optional embodiment of this utility model, the thermal insulation material 4 is expanded perlite and / or glass microspheres.

[0035] In this embodiment, the thermal insulation material 4 can be expanded perlite or glass microspheres, or a mixture of the two. Expanded perlite and glass microspheres are granular materials with good thermal insulation effect and can be easily entered into the cavity 3 through the filling port 5 or poured out of the cavity 3 through the discharge port 6. At the same time, after the expanded perlite and glass microspheres enter the cavity 3, since both are hard materials, when a vacuum is formed in the cavity 3, they can also provide good support for the outer tank 1 and the inner tank 2, preventing the outer tank 1 and the inner tank 2 from deforming due to air pressure.

[0036] In an optional embodiment of this utility model, a first sealing cover is provided on the top of the filling port 5. The first sealing cover is fixedly connected to the filling port 5 by threads, and a sealing rubber ring is provided between the first sealing cover and the filling port 5.

[0037] The top of the discharge port 6 is provided with a second sealing cover, which is fixedly connected to the discharge port 6 by threads, and a sealing rubber ring is provided between the second sealing cover and the discharge port 6.

[0038] The inner tank 2 has a feed inlet at the top, and a feed cover 7 is provided at the top of the feed inlet. The feed cover 7 is fixedly connected to the feed inlet by threads, and a sealing ring is provided between the feed cover 7 and the feed inlet.

[0039] In this embodiment, the insulation material 4 is filled into the cavity 3 through the filling port 5; when the insulation material 4 needs to be replaced, it can be poured out from the discharge port 6; during normal use of the insulation tank, a vacuum state needs to be formed in the cavity 3 to improve the insulation effect, so the filling port 5 and the discharge port 6 need to be sealed; the seal can be formed by a screw-tight sealing cap, wherein the first sealing cap is used to seal the filling port 5 and the second sealing cap is used to seal the discharge port 6; in order to improve the sealing effect, sealing rings can also be set between the first sealing cap and the filling port 5, and between the second sealing cap and the discharge port 6;

[0040] To facilitate the easy loading and unloading of materials stored in the inner tank 2, a feed inlet needs to be provided on the inner tank 2. As a preferred option, the feed inlet can be located at the top of the inner tank 2. Similarly, the materials stored in the inner tank 2 also need to be sealed to prevent heat exchange with the outside environment, thereby improving the insulation effect. Therefore, a feed cover 7 is provided at the top of the feed inlet. The feed cover 7 is also fixedly connected to the feed inlet by means of threads, and a sealing ring is provided between the feed cover 7 and the feed inlet to improve the insulation effect.

[0041] In an optional embodiment of this utility model, the outer surface of the outer tank 1 is further provided with an air extraction valve 8, and the first air port of the air extraction valve 8 is connected to the cavity 3.

[0042] After the cavity 3 is filled with the thermal insulation material 4, the air in the cavity 3 is discharged through the air extraction valve 8, so that a vacuum is formed in the cavity 3.

[0043] In this embodiment, an air extraction valve 8 is installed on the outer surface of the outer tank 1. The air extraction valve 8 has a first air port, which is connected to the cavity 3 inside the insulation tank. Before the insulation material 4 is filled, some air will inevitably exist in the cavity 3. To maximize the insulation effect, this air needs to be expelled as much as possible, as the presence of air will reduce the insulation performance of the insulation material 4. Therefore, after the insulation material 4 is filled, the air extraction valve 8 is used to perform an air venting operation. Specifically, the air extraction valve 8 is opened to connect it to an external vacuum pump or other air extraction equipment. Then, the air extraction equipment is started, and the air in the cavity 3 is extracted through the first air port of the air extraction valve 8. As the air is gradually expelled, the pressure inside the cavity 3 will gradually decrease until a near-vacuum state is formed. When the air in the cavity 3 is completely expelled and a vacuum is formed, the air extraction valve 8 can be closed. At this time, the insulation performance of the insulation tank will be significantly improved because the vacuum state almost completely blocks the heat transfer path, allowing the insulation tank to better maintain the stability of the internal temperature. The insulation material 4 can also provide support in the cavity 3, preventing the outer tank 1 and the inner tank 2 from deforming due to air pressure.

[0044] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
