Description

Technical Field

[0001] The utility model relates to the technical field of solar water heaters, in particular to a pressure-bearing multi-compartment solar water heater water tank. Background Art

[0002] The existing domestic solar water heater tank is usually an open water tank, which has the characteristics of having an exhaust pipe connected to the atmosphere and relying on the vertical height difference between the water tank and the ground to obtain a certain water outlet pressure. However, in real life, the location where the equipment is installed may not necessarily be able to obtain the ideal height difference. If you want to increase the hot water flow and flow rate, you usually use a booster pump to achieve this. When the booster pump works normally, the hot water outlet pressure is constant. At this time, if the cold water pressure changes, it is easy to cause the problem of imbalance between the cold and hot water pressures, which eventually leads to the outlet temperature being hot and cold.

[0003] In order to solve this problem, a double-layer inner tank insulated water tank has been disclosed. A pressure tank is nested inside the traditional heat collecting tank. The heat absorbed by the heat collecting tube increases the temperature of the liquid between the heat collecting tank and the pressure tank, and then the high-temperature liquid is used to heat the water in the pressure tank. Although the problem of the water temperature fluctuating can be solved to a certain extent, since the water use method is top water type, the cold water inlet and the hot water outlet are synchronized, which inevitably produces the phenomenon of cold and hot water mixing, resulting in a significant reduction in the amount of hot water obtained during actual use. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a pressurized multi-compartment solar water heater water tank, which can reduce the mixing degree of cold and hot water, reduce the reduction of hot water heat, and improve the utilization rate of hot water; and the pressures of cold and hot water are the same, and water is taken under pressure, so the outlet water temperature will not fluctuate between cold and hot when using water.

[0005] In order to solve the above technical problems, the technical solution of the utility model is a pressurized multi-compartment solar water heater tank, comprising an outer shell, an insulation layer and a heat collecting inner tank; at least two pressurized inner tanks are embedded in the internal cavity of the heat collecting inner tank; a socket for installing an all-glass vacuum solar collector tube is provided at the lower part of the heat collecting inner tank; a pipe is connected between the ends of two adjacent pressurized inner tanks, and the ends are fixedly connected by a connecting assembly.

[0006] Furthermore, the connection assembly includes a plurality of connectors; two ends of the connectors are respectively fixedly connected to the ends of the two pressure-bearing inner tanks.

[0007] Furthermore, the connection assembly includes a plurality of ring sleeves; the ring sleeves are fixedly connected to the outer walls of the two pressure-bearing inner tanks.

[0008] Furthermore, the pipeline is located above the horizontal center line of the pressure-bearing liner.

[0009] Furthermore, a first internally threaded tube and a second internally threaded tube penetrating the thermal insulation layer and the heat collecting inner tank are respectively fixedly connected between the bottom of the two pressure-bearing inner tanks located at both ends and the outer shell; the upper end of the second internally threaded tube extends to the upper part of the inner cavity of the pressure-bearing inner tank; the upper end of the first internally threaded tube is connected to the bottom of the pressure-bearing inner tank.

[0010] Furthermore, a fourth internally threaded tube and a fifth internally threaded tube that penetrate the thermal insulation layer and the heat collecting tank are respectively fixedly connected between the ends of the two pressure-bearing tanks located at both ends and the outer shell; one end of the fourth internally threaded tube and the fifth internally threaded tube both extend into the inner cavity of the pressure-bearing tank and are located at the upper part of the inner cavity of the pressure-bearing tank.

[0011] Furthermore, a sixth internally threaded tube and a seventh internally threaded tube penetrating the thermal insulation layer are fixedly connected between the top of the outer shell and the top of the thermal collector inner tank; the lower ends of the sixth internally threaded tube and the seventh internally threaded tube are both connected to the top of the inner cavity of the thermal collector inner tank.

[0014] Furthermore, a plurality of convection pipes are fixedly connected between the upper and lower walls of each of the pressure-bearing inner tanks; both ends of the convection pipes are connected to the cavity formed between the heat collecting inner tank and the pressure-bearing inner tank.

[0015] Beneficial effects of the utility model:

[0016] At least two interconnected pressure tanks are nested inside the traditional heat collection tank, and the cold water inlet and hot water outlet are set on different pressure tanks.

DETAILED DESCRIPTION

[0020] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0021] Example 1

[0022] A pressurized multi-compartment solar water heater tank, such as Figure 1 As shown, it includes an outer shell 1, an insulation layer 2 and a heat collecting inner tank 3; at least two pressure-bearing inner tanks 4 are embedded in the internal cavity of the heat collecting inner tank 3; a socket 5 for installing a full-glass vacuum solar heat collecting tube is provided at the lower part of the heat collecting inner tank 3; a pipe 7 is connected between the ends of two adjacent pressure-bearing inner tanks 4, and the ends are fixedly connected by a connector 6.

[0023] The above-mentioned pressurized multi-compartment solar water heater tank is achieved by nesting at least two mutually connected pressurized inner tanks 4 inside the heat collecting inner tank 3, and setting the cold water inlet and the hot water outlet on different pressurized inner tanks 4. Since the pressurized inner tanks 4 are independent of each other, the degree of heat exchange between cold and hot water can be greatly reduced, the degree of mixing between cold and hot water can be reduced, the reduction in the heat of hot water can be reduced, and the utilization rate of hot water can be improved; and since the pressurized inner tanks 4 are connected by pipes 7, the same pressure of cold and hot water can still be achieved, and water can be taken under pressure without the situation where the outlet water temperature fluctuates.

[0024] Specifically, the connection assembly includes a plurality of connectors 6 and annular sleeves 19; the two ends of the connectors 6 are respectively fixedly connected to the ends of the two pressure-bearing inner tanks 4; and the annular sleeves 19 are fixedly connected to the outer walls of the two pressure-bearing inner tanks 4. The connectors 6 and the annular sleeves 19 can improve the connection strength between adjacent pressure-bearing inner tanks 4.

[0025] Specifically, the first internally threaded tube 8 and the second internally threaded tube 9 penetrating the thermal insulation layer 2 and the heat collecting inner tank 3 are respectively fixedly connected between the bottom of the two pressure-bearing inner tanks 4 at both ends and the outer shell 1; the upper end of the second internally threaded tube 9 extends to the upper part of the inner cavity of the pressure-bearing inner tank 4; the upper end of the first internally threaded tube 8 is connected to the bottom of the pressure-bearing inner tank 4. The cold water inlet pipe is connected to the lower part of the left pressure-bearing inner tank 4 through the first internally threaded tube 8, and the hot water outlet pipe is connected to the lower part of the right pressure-bearing inner tank 4 through the second internally threaded tube 9. When in use, cold water enters the inner cavity of the left pressure-bearing inner tank 4 through the cold water inlet pipe, and the hot water in the right pressure-bearing inner tank 4 is squeezed out through the hot water outlet pipe under the action of water pressure.

[0026] Specifically, the pipe 7 is located above the horizontal center line of the pressure tank 4 , so that the hot water at the upper part of the left pressure tank 4 preferentially flows through the pipe 7 to the right pressure tank 4 .

[0027] Specifically, the fourth internally threaded tube 11 and the fifth internally threaded tube 12 penetrating the thermal insulation layer 2 and the heat collecting inner tank 3 are respectively fixedly connected between the ends of the two pressure-bearing inner tanks 4 located at both ends and the outer shell 1; one end of the fourth internally threaded tube 11 and the fifth internally threaded tube 12 both extend into the inner cavity of the pressure-bearing inner tank 4 and are located at the upper part of the inner cavity of the pressure-bearing inner tank 4. On the one hand, the fourth internally threaded tube 11 can be used to install a vacuum eliminator, and the fifth internally threaded tube 12 can be used to install a pressure relief valve. When the pressure in the pressure-bearing inner tank 4 is large or a large negative pressure is generated, the pressure can be balanced by the pressure relief valve and the vacuum eliminator to prevent the pressure-bearing inner tank 4 from being deformed. On the other hand, the fourth internally threaded tube 11 and the fifth internally threaded tube 12 can also play a role in fixing and supporting the pressure-bearing inner tank 4. When the pressure relief valve and the vacuum eliminator are not installed, a heat-insulating plug can be installed in the fourth internally threaded tube 11 and the fifth internally threaded tube 12 to prevent heat loss and dust from entering.

[0028] Specifically, the sixth internally threaded tube 13 and the seventh internally threaded tube 14 penetrating the thermal insulation layer 2 are fixedly connected between the top of the outer shell 1 and the top of the heat collecting inner tank 3; the lower ends of the sixth internally threaded tube 13 and the seventh internally threaded tube 14 are both connected to the top of the inner cavity of the heat collecting inner tank 3. The sixth internally threaded tube 13 and the seventh internally threaded tube 14 can be connected to the liquid replenishing tube and the exhaust pipe respectively, and are used to add heat-conducting liquid to the cavity between the heat collecting inner tank 3 and the pressure-bearing inner tank 4, and balance the pressure when the pressure in the cavity changes greatly.

[0029] Specifically, an eighth internally threaded tube 16 and a ninth internally threaded tube 17 penetrating the thermal insulation layer 2 and the heat collecting inner tank 3 are respectively fixedly connected between the bottom of the two pressure-bearing inner tanks 4 at both ends and the outer shell 1; the upper ends of the eighth internally threaded tube 16 and the ninth internally threaded tube 17 are both connected to the bottom of the inner cavity of the pressure-bearing inner tank 4. The eighth internally threaded tube 16 and the ninth internally threaded tube 17 can be used to connect the water inlet pipe and the water outlet pipe of other external equipment (electric water heater, steam generator, natural gas water heater, combustion boiler or circulating air energy water heater, etc.). For example, the eighth internally threaded tube 16 can be connected to the water outlet pipe of the air energy water heater or the electric water heater water tank by a pipe, and the ninth internally threaded tube 17 can be connected to the water inlet pipe of the air energy water heater or the electric water heater water tank by a pipe.

[0030] Specifically, a third internally threaded tube 10 penetrating the thermal insulation layer 2 and the heat collecting inner tank 3 is fixedly connected between the bottom of the pressure-bearing inner tank 4 connected with the second internally threaded tube 9 and the outer shell 1; the top of the third internally threaded tube 10 is connected to the bottom of the inner cavity of the pressure-bearing inner tank 4. The third internally threaded tube 10 can be used to connect a sewage pipe to facilitate cleaning of scale in the pressure-bearing inner tank 4. A tenth internally threaded tube 18 penetrating the thermal insulation layer 2 is fixedly connected between the bottom of the heat collecting inner tank 3 and the outer shell 1; the top of the tenth internally threaded tube 18 is connected to the bottom of the inner cavity of the heat collecting inner tank 3. The tenth internally threaded tube 18 can be used to connect a sewage pipe to facilitate cleaning of scale in the heat collecting inner tank 3.

[0031] Example 2

[0032] A pressurized multi-compartment solar water heater tank, such as Figure 2 As shown, a convection pipe 15 is added on the basis of Example 1. Specifically, a plurality of convection pipes 15 are fixedly connected between the upper and lower walls of each pressure-bearing inner tank 4; both ends of the convection pipe 15 are connected to the cavity formed between the heat collecting inner tank 3 and the pressure-bearing inner tank 4. The high-temperature liquid in the cavity between the pressure-bearing inner tank 4 and the heat collecting inner tank 3 can flow through the convection pipe 15, which can accelerate the flow speed of the high-temperature liquid on the one hand, and increase the heat exchange area between the high-temperature liquid and the pressure-bearing inner tank on the other hand, thereby improving the heat exchange efficiency.

[0033] The working principle of this utility model:

[0034] The heat of solar energy absorbed by the heat collecting tube increases the temperature of the liquid between the heat collecting inner tank and the pressure inner tank, and then the high-temperature liquid is used to heat the water in the pressure inner tank. When in use, cold water enters the left pressure inner tank 4 through the cold water inlet pipe connected to the first internal threaded pipe 8 under the action of the pump, and the hot water in the right pressure inner tank 4 is squeezed out through the hot water outlet pipe connected to the second internal threaded pipe 9 under the action of water pressure.

[0035] By nesting at least two interconnected pressure tanks 4 inside the heat collection tank 3, and setting the cold water inlet and hot water outlet on different pressure tanks 4, since the pressure tanks 4 are independent of each other, the heat exchange degree of cold and hot water can be greatly reduced, the mixing degree of cold and hot water can be reduced, the heat reduction of hot water can be reduced, and the utilization rate of hot water can be improved; and since the pressure tanks 4 are connected by pipes 7, the pressure of cold and hot water can still be the same, and water can be taken under pressure without the situation of the outlet water temperature being hot and cold. The more the number of pressure tanks 4, the lower the mixing degree of cold and hot water.

[0036] When the solar water heater cannot meet the hot water demand due to rain or snow, additional heating can be provided by additional equipment (electric water heater, steam generator, natural gas water heater, combustion boiler or circulating air energy water heater, etc.) to achieve 24-hour hot water supply. The temperature of the water stored in the rightmost pressure water tank 4 is relatively the highest. When its temperature still cannot meet the water demand due to weather reasons, the water in the rightmost pressure water tank 4 is controlled to enter the additional equipment, and after being heated by the additional equipment, it flows into the leftmost pressure tank 4, and finally flows into the rightmost pressure tank 4, forming a water circulation path, so that the water temperature is increased to meet the water demand.

[0037] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
