Description

Technical Field

[0001] The utility model relates to the technical field of chemical production, and more specifically to a heat-insulating storage tank. Background Art

[0002] The chemical production industry requires large storage tanks to store products and raw materials. These tanks can be made of metal materials such as carbon steel and stainless steel, non-metallic materials such as plastic and fiberglass, or composite materials such as steel-lined PTFE tanks. Metal is the most commonly used material for large-scale storage tanks due to cost and capacity considerations. However, metal tanks have some disadvantages. Due to their high thermal conductivity, they are more susceptible to temperature changes. This can be a significant problem if the chemical products stored in them require high storage temperatures. Utility Model Content

[0003] One advantage of the present invention is that it provides a heat-insulating storage tank. In view of the fact that the temperature required for chemical products is within a temperature range, a heat-insulating layer, a heating layer and a reflecting layer are provided, which is suitable for use in various seasons. In the summer when the sun is strong, most of the heat radiation can be reflected back, thereby reducing the impact of heat radiation on the temperature of the tank body. In the winter when the temperature is low, not only the heat-insulating layer can reduce the impact of the external low temperature on the tank body, but the heating layer can also generate heat independently, forming a temperature separation zone between the heat-insulating layer and the reflecting layer, which can both block the external cold air and prevent the temperature of the tank body from rising due to heating, thereby ensuring that the tank body can be maintained within a suitable temperature range.

[0004] In order to achieve at least one of the above advantages of the present invention, the present invention provides a thermal insulation storage tank, including a tank body, and an insulation jacket is provided on the outside of the tank body. The insulation jacket includes a radiation reflection layer, a heat insulation layer, a heat-generating layer, a heat insulation layer and a heat reflection layer arranged in sequence from the outside to the inside.

[0005] According to an embodiment of the present invention, the exterior of the radiation reflecting layer is coated with an infrared reflecting pigment having a high reflectivity.

[0006] According to an embodiment of the present invention, the heat insulation layer is made of one or more of glass fiber, asbestos, and rock wool.

[0007] According to an embodiment of the present invention, a heating wire is provided inside the heating layer, and the heating wire is connected to a power supply device.

[0008] According to an embodiment of the present invention, the heating wire is arranged in a spiral manner from bottom to top around the tank body.

[0009] According to an embodiment of the present invention, heat reflective cloths are provided on both the inner and outer sides of the heat reflective layer, and the heat reflective cloths are made of heat reflective ceramic fabrics.

[0010] According to an embodiment of the present invention, a plurality of supporting legs are provided at the lower portion of the tank body. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the above terms cannot be understood as limiting the present invention.

[0017] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0018] The utility model provides a thermal insulation storage tank, including a tank body 1, an insulation sleeve 2 is provided on the outside of the tank body 1, and the insulation sleeve 2 includes a radiation reflection layer 21, a heat insulation layer 22, a heating layer 23, a heat insulation layer 22 and a heat reflection layer 24 arranged in sequence from the outside to the inside; the outside of the radiation reflection layer 21 is coated with an infrared reflection pigment with high reflectivity; the heat insulation layer 22 is made of one or more of glass fiber, asbestos, and rock wool; the inside of the heating layer 23 is provided with a heating wire, and the heating wire is connected to a power supply device; the heating wire is arranged in a spiral rising manner from bottom to top around the tank body 1; heat reflection cloth is provided on both the inside and outside of the heat reflection layer 24, and the heat reflection cloth is made of heat reflection ceramic fabric; a plurality of supporting legs are provided at the lower part of the tank body 1.

[0019] The first embodiment of the present utility model is as follows:

[0020] A heat-insulating storage tank includes a tank body 1. A plurality of legs are provided at the lower portion of the tank body 1 to support the tank body 1 so as to leave a certain gap between the tank body 1 and the ground, thereby reducing the influence of cold air from the ground on the temperature of the tank body 1.

[0021] An insulation sleeve 2 is provided on the outside of the tank body 1. Except for the necessary reserved gaps, the insulation sleeve 2 completely covers the surface of the tank body 1, including the sides and the upper and lower surfaces, which may reduce the position of the cold bridge and ensure the insulation effect. The insulation sleeve 2 includes a radiation reflection layer 21, an insulation layer 22, a heating layer 23, an insulation layer 22 and a heat reflection layer 24 arranged in sequence from the outside to the inside.

[0022] The radiation reflection layer 21 is coated with infrared reflection pigment with high reflectivity on the outside, which reflects infrared light in sunlight back, thereby reducing heat accumulation and playing a cooling role, ensuring that the temperature of the tank body 1 will not rise too high due to exposure to the sun in summer.

[0023] An insulation layer 22 is provided inside the radiation reflection layer 21. The insulation layer 22 is made of one or more materials such as glass fiber, asbestos and rock wool, which can reduce the heat transfer. Whether in winter or summer, it can reduce the influence of the external temperature on the tank body 1. The insulation layer 22 has two layers. A heating layer 23 is provided between the two insulation layers 22. In the winter in the north, especially in the northeast, the temperature may drop to minus 30 to 40 degrees Celsius. It is no longer possible to meet the requirements by only using the insulation layer 22 for heat preservation, so a heating layer 23 is required. The heating layer 23 has a heating wire inside, which is connected to a power supply device. When the heating wire is energized, it will generate heat on its own, thereby increasing the temperature of the heating layer 23. Since the heating layer 23 is located between the two layers of thermal insulation layers 22, it can cooperate with the thermal insulation layer 22 to form an autonomous heating and heat insulation system, so that when the external low temperature is conducted to the heating layer 23, it cannot be further conducted to the inside. At the same time, the heat generated by the heating layer 23 will also be blocked by the inner thermal insulation layer 22 and will not be conducted to the tank body 1, so as to avoid causing the temperature of the tank body 1 to rise above the threshold.

[0024] The heating wires are arranged in a spiral manner from bottom to top around the tank body 1 to ensure that no heat gap is left.

[0025] Inside the inner insulation layer 22 is a heat reflecting layer 24. Heat reflecting cloth is provided on both the inner and outer sides of the heat reflecting layer 24. The heat reflecting cloth is made of heat reflecting ceramic fabric, which can play a good infrared reflection and radiation effect, form a stable temperature environment, and has a good warming effect.

[0026] The thermal insulation jacket 2 can keep the temperature of the tank body 1 within a certain suitable range, and will not cause a significant change in the tank body 1 due to the external temperature being too high or too low, making it suitable for chemical storage.

[0027] It should be noted that the terms "first, second and third" in the present invention are only used for descriptive purposes and do not indicate any order. They cannot be understood as indicating or implying relative importance. These terms can be interpreted as names.

[0028] Those skilled in the art will appreciate that the embodiments of the present invention described above and shown in the accompanying drawings are intended only as examples and do not limit the present invention. The advantages of the present invention have been fully and effectively achieved. The functional and structural principles of the present invention have been demonstrated and illustrated in the embodiments. Any variations or modifications may be made to the embodiments of the present invention without departing from the principles herein.
