Description

Technical Field

[0001] This utility model relates to the field of hot water tank technology, specifically a layered insulation system for hot water tanks. Background Technology

[0002] A hot water tank is a container used to store and supply hot water. It is divided into vertical hot water tanks and horizontal hot water tanks. It is often used for heat energy recycling and hot water supply. It is widely used in hot water supply systems such as solar energy, hot water boilers, and air source heat pumps. It is also very common in industrial production.

[0003] Most existing hot water tanks are single-layer tank structures with an additional insulation layer. When storing hot water, heat loss occurs through external heat dissipation. In single-layer hot water tanks, the heat transfer path between the hot water inside and the external environment is relatively short and direct. Relying solely on the insulation layer for heat preservation results in poor insulation performance, easy heat loss, and wasted heat. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a layered insulation system for hot water tanks, which solves the problem that most existing hot water tanks have a single-layer tank structure, leading to easy heat dissipation.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A layered insulation system for hot water tanks includes three horizontal cylindrical tanks nested together. The three horizontal cylindrical tanks are coaxially arranged, and partition plates are fixed at both ends of each horizontal cylindrical tank. Spherical end caps are fixed at positions on the outermost horizontal cylindrical tank, with the partition plates facing away from each other. One end of each horizontal cylindrical tank is provided with an inlet pipe that passes through one of the spherical end caps and the partition plate and communicates with the inner horizontal cylindrical tank. An outlet pipe is connected to the bottom of the outermost horizontal cylindrical tank. Small end caps are fixed on the side of the partition plate opposite to the liquid inlet pipe of the middle layer horizontal cylindrical tank. Overflow holes are provided on both partition plates at the positions corresponding to the inner wall of the middle layer horizontal cylindrical tank and the positions corresponding to the inner wall of the outermost horizontal cylindrical tank. Overflow holes are also provided on the partition plate opposite to the liquid inlet pipe at the position corresponding to the inner wall of the inner layer horizontal cylindrical tank. The horizontal cylindrical tank, spherical head, and small head all consist of a steel shell and a polyurethane interlayer. The upper half of the outer wall of the spherical head and the upper half of the outer wall of the outermost horizontal cylindrical tank are coated with a composite silicate insulation layer. The lower half of the outer wall of the spherical head and the lower half of the outer wall of the outermost horizontal cylindrical tank are coated with an aerogel insulation layer.

[0006] Preferably, the outer wall of the spherical head and the outer wall of the outermost horizontal cylindrical tank are both wrapped with a polyurethane foam insulation layer located outside the composite silicate insulation layer and the aerogel insulation layer.

[0007] Preferably, a level gauge is installed on the spherical end cap opposite to the liquid inlet pipe, and the connecting pipe of the level gauge passes through the polyurethane foam insulation layer, the composite silicate insulation layer, the aerogel insulation layer and the spherical end cap and extends to the inside of the spherical end cap.

[0008] Preferably, the inlet pipe is located on the horizontal axis of the horizontal cylindrical tank, and the outlet pipe is located on the vertical axis of the horizontal cylindrical tank.

[0009] Preferably, an electronic thermometer is installed on the outermost horizontal cylindrical tank. The electronic thermometer is located in the middle of the horizontal cylindrical tank, and the probe of the electronic thermometer is located inside the outermost horizontal cylindrical tank at the position corresponding to the liquid outlet pipe.

[0010] Preferably, the overflow holes are equidistantly arranged circumferentially on the partition plate, and overflow holes are also present at corresponding positions on the bottom of the inner wall of the horizontal cylindrical tank.

[0011] Compared with the prior art, the present invention has the following beneficial effects: (1) This utility model is constructed by setting up a multi-layer horizontal cylindrical tank with partition plates, small end caps and spherical end caps to form a multi-layer structure. The tank components are all sandwich structures including steel shell and polyurethane interlayer, so that the heat transferred from the internal hot water to the outside is intercepted layer by layer, achieving the effect of layered heat preservation, reducing heat loss, and being more energy-saving and environmentally friendly. It solves the problem that most existing hot water tanks are single-layer tank structures, which makes them easy to dissipate heat.

[0012] (2) In addition to the polyurethane foam insulation layer on the outside, the hot water tank of this utility model is also provided with a composite silicate insulation layer and an aerogel insulation layer. The lower part uses the aerogel insulation layer 9, which has a better effect but is more expensive, and the upper part uses the more commonly used composite silicate insulation layer 8, which has a lower effect than the aerogel insulation layer 9 but is cheaper. Taking into account the insulation effect and cost, it is more economical and practical. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figure 1-4 As shown, this utility model provides a technical solution: a layered insulation system for hot water tanks, including three horizontal cylindrical tanks 1 nested in layers. The three horizontal cylindrical tanks 1 are coaxially arranged, and partition plates 2 are fixed at both ends of the horizontal cylindrical tanks 1. Spherical end caps 3 are fixed at the positions of the outermost horizontal cylindrical tank 1 on the two partition plates 2 facing away from each other. One end of the horizontal cylindrical tank 1 is provided with a liquid inlet pipe 4 that passes through one of the spherical end caps 3 and the partition plate 2 and is connected to the inner horizontal cylindrical tank 1. The liquid inlet pipe 4 is arranged on the horizontal axis of the horizontal cylindrical tank 1. The bottom of the outermost horizontal cylindrical tank 1 is connected to a liquid outlet pipe 5, which is set on the vertical axis of the horizontal cylindrical tank 1. An electronic thermometer 11 is installed on the outermost horizontal cylindrical tank 1. The electronic thermometer 11 is located in the middle of the horizontal cylindrical tank 1, and the probe 1101 of the electronic thermometer 11 is located inside the outermost horizontal cylindrical tank 1 at the position corresponding to the liquid outlet pipe 5. A small end cap 6 is fixed on the side of the partition plate 2 at the end opposite to the liquid inlet pipe 4 of the middle layer horizontal cylindrical tank 1. Overflow holes 7 are provided at the positions of the two partition plates 2 corresponding to the inner wall of the middle layer horizontal cylindrical tank 1 and the inner wall of the outermost horizontal cylindrical tank 1. Overflow holes 7 are also provided at the positions of the partition plates 2 at the ends opposite to the liquid inlet pipe 4 corresponding to the inner wall of the inner layer horizontal cylindrical tank 1. The overflow holes 7 are equidistantly arranged on the partition plates 2 along the circumference, and there are overflow holes 7 at the corresponding positions at the bottom of the inner wall of the horizontal cylindrical tank 1, which facilitates the flow of hot water from the inside to the outside and avoids water accumulation that cannot be discharged. The horizontal cylindrical tank 1, the spherical head 3 and the small head 6 all contain a steel shell 01 and a polyurethane interlayer 02. The upper half of the outer wall of the spherical head 3 and the upper half of the outer wall of the outermost horizontal cylindrical tank 1 are coated with a composite silicate insulation layer 8. The lower half of the outer wall of the spherical head 3 and the lower half of the outer wall of the outermost horizontal cylindrical tank 1 are coated with an aerogel insulation layer 9. It is not always filled with hot water. Many times it is not filled or is used after being filled, resulting in an incomplete tank. In the case of an incomplete tank, the hot water inside is concentrated at the bottom. Considering both the insulation effect and cost, the lower part uses a more effective but more expensive aerogel insulation layer 9, while the upper part uses a more commonly used composite silicate insulation layer 8, which is less effective than the aerogel insulation layer 9 but cheaper. The outer wall of the spherical head 3 and the outer wall of the outermost horizontal cylindrical tank 1 are both covered with a polyurethane foam insulation layer 10 located outside the composite silicate insulation layer 8 and the aerogel insulation layer 9. A liquid level gauge 12 is installed on the spherical head 3 at the end opposite to the liquid inlet pipe 4. The connecting pipe 1201 of the liquid level gauge 12 passes through the polyurethane foam insulation layer 10, the composite silicate insulation layer 8, the aerogel insulation layer 9 and the spherical head 3 and extends to the inner side of the spherical head 3.

[0017] Working principle: Hot water first enters the inner horizontal cylindrical tank 1 through the inlet pipe 4. Under the action of the overflow hole 7 on the partition plate 2, it flows outward layer by layer from the inner horizontal cylindrical tank 1, filling the lower half of the hot water tank. Hot water continues to be poured in, gradually filling the hot water tank. Therefore, the lower half of the outer wall uses a more effective but more expensive aerogel insulation layer 9, while the upper half of the outer wall uses a more commonly used, less effective but cheaper composite silicate insulation layer 8, balancing the insulation effect and cost. The internal liquid level can be monitored by the level gauge 12, and the temperature of the hot water discharged from the outlet pipe 5 can be monitored by the electronic thermometer 11. By setting up a multi-layer horizontal cylindrical tank 1, partition plate 2, small end cap 6 and spherical end cap 3 to form a multi-layer structure, the tank components are all sandwich structures including a steel shell 01 and a polyurethane interlayer 02, so that the heat transferred from the internal hot water to the outside is intercepted layer by layer, achieving the effect of layered insulation, thereby reducing heat loss and making it more energy-saving and environmentally friendly.
