Description

Technical Field

[0001] This utility model belongs to the field of heating and heating devices, specifically relating to a multi-cavity heat storage heating and heating device. Background Technology

[0002] In the heating and cooling industry, traditional equipment is typically "water-tube" and "fire-tube" boilers. "Water-tube" boilers place heat exchange mediums such as water, steam, or steam-water mixtures inside the tubes and provide heat by means of the combustion flow of flames or flue gas outside the tubes. "Fire-tube" boilers allow the flue gas generated by fuel combustion to flow inside the fire tube or flue to heat the working medium outside the tubes. Although they have large water capacity, strong heat storage capacity, and simple structure, installation and operation, they have the disadvantages of large overall size and low thermal efficiency.

[0003] Existing heating devices cannot achieve efficient coordination of multi-cavity heat exchange, nor can they combine with other chambers to achieve cascade utilization of heat energy and reduce heat loss, which requires further improvement. Utility Model Content

[0004] To overcome the problem that existing heating devices cannot achieve efficient coordination of multi-cavity heat exchange and cannot combine with other chambers to achieve cascade utilization of heat energy and reduce heat loss, a multi-cavity heat storage and heating device is proposed.

A water replenishment tank is fixed to the side wall of the first water tank. A first connecting block is fixed to the inner wall of the first water tank. A first inner tank is fixed to the end of the first connecting block near the center of the first water tank. A second connecting block is fixed to the inner wall of the first inner tank. A second inner tank is fixed to the end of the second connecting block near the center of the first inner tank. Multiple electric heating rods are fixed to the bottom surface of the inner wall of the second inner tank. A second water tank is fixed to the center of the bottom surface of the inner wall of the second inner tank. A lower fixed pipe is fixed to the lower end of the second water tank. The lower end of the lower fixed pipe passes through the lower end of the second inner tank and extends to the bottom of the second inner tank.

[0006] The support frame is equipped with a circulation mechanism. The outlet end of the circulation mechanism is connected to the inlet end of the lower fixed pipe. At least two hot water pipes are fixedly connected to one end through the inner wall of the first water tank. The other end of the hot water pipes passes through the first fixed cylinder and is fixed to the inside of the heat dissipation coil.

[0007] The upper end of the second inner tank is fixedly connected to the second fixed cylinder, the upper end of the second fixed cylinder is fixedly connected to the upper end of the inner wall of the first inner tank, and a connecting groove is opened through the side wall of the second fixed cylinder.

[0008] A water storage chamber is formed between the first inner tank and the first water tank, and a heat storage chamber is formed between the first inner tank and the second inner tank. An upper fixed pipe is fixedly connected to the upper end of the second water tank. The upper end of the upper fixed pipe passes through the first inner tank and extends into the water storage chamber. The outlet pipe of the heat dissipation coil is connected to the inlet of the water supply tank.

[0009] Furthermore, the circulation mechanism includes a support block fixed to the inner wall of the support frame and a pump body fixed to the upper end of the support block. One end of the pump body is fixed to the water pumping end, and the other end of the water pumping end is fixed to the water outlet end of the water replenishment tank. One end of the pump body is fixed to the water outlet end, and the other end of the water outlet end passes through the first water tank and the first inner tank and is fixed to the water inlet end of the lower fixed pipe.

[0010] Furthermore, one end of a connecting pipe is fixedly connected to the lower end of the first inner tank, and the other end of the connecting pipe passes through the support frame, the first water tank, the first inner tank and the second inner tank in sequence and extends into the interior of the second inner tank.

[0011] Furthermore, a first valve body is provided on the connecting pipe.

[0012] Furthermore, the lower end of the first inner tank is hemispherical.

[0013] Furthermore, the portion of the connecting pipe located at the lower end of the first inner tank is coaxially arranged with the lower fixed pipe.

[0014] Furthermore, the upper fixed pipe and the first inner tank are coaxially arranged.

[0015] Furthermore, a water supply pipe is fixedly connected through the water supply tank, and a second valve body is installed on the water supply pipe.

[0016] The beneficial effects of this utility model are:

[0017] 1. By using the nested structure of the heat storage chamber and the water storage chamber and the design of the connecting groove, the problem of easy heat loss in traditional boilers is solved: The heat storage chamber (which can be filled with liquid heat storage medium) formed between the first inner tank and the second inner tank can achieve free flow of the heat storage medium through the connecting groove on the side wall of the second fixed cylinder. At the same time, the water storage chamber formed between the first inner tank and the first water tank is sleeved on the outside of the heat storage chamber, which facilitates the heating of the water in the water storage chamber. When the high-temperature medium in the heat storage chamber passes through the connecting groove, the heat is first transferred to the water storage chamber through the walls of the second inner tank and the first inner tank, and then transported to the heat dissipation coil by the hot water pipe, which reduces the direct loss of heat to the external environment. In addition, the hemispherical design at the bottom of the first inner tank not only guides the heat storage medium to gather at the bottom, but also, in conjunction with the slight disturbance generated when the outlet pipe of the circulation mechanism replenishes water to the second water tank, further enhances the heat exchange efficiency when the medium flows.

[0018] 2. Through the coordinated operation of the circulation mechanism and multiple chambers, the cascade utilization of thermal energy is realized, solving the problem of low thermal efficiency of traditional equipment: In the circulation mechanism, the pump body draws water from the water supply tank through the water pumping pipe, and delivers it to the lower fixed pipe through the water outlet pipe and enters the second water tank. After the cold water is initially heated by the electric heating rod in the second water tank, it enters the water storage chamber through the upper fixed pipe. At the same time, the high-temperature medium in the heat storage chamber flows through the connecting groove under the action of thermal convection, continuously replenishing the heat of the water storage chamber. When the hot water pipe delivers the hot water in the water storage chamber to the heat dissipation coil, the return water that has not been completely cooled can flow back to the water supply tank, which facilitates the recycling of water.

[0019] 3. By adopting a coaxial nested design of the first inner tank, the second inner tank, and the second water tank, the heat storage chamber, the water storage chamber, and the circulation pipeline (lower fixed pipe, upper fixed pipe, and connecting pipe) are all integrated in the closed space formed by the support frame and the first water tank. At the same time, the medium in the heat storage chamber forms turbulent flow through the connecting groove under the action of thermal convection (in conjunction with the power of the pump body), and the water in the water storage chamber forms convection through the jet action of the upper fixed pipe. The combination of the two greatly increases the heat exchange per unit time. The water supply tank replenishes water as needed through the water supply pipe (by opening the second valve body). With the continuous power of the circulation mechanism, the heating lag problem caused by the large water capacity of traditional boilers is avoided, and stable heating is achieved.

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] Please see Figures 1-6 This utility model provides an embodiment of a multi-cavity thermal storage and heating device, including a support frame 1, a first water tank 2 fixed to the upper end of the support frame 1, a first fixed cylinder 3 fixed to the upper part of the side wall of the first water tank 2, and a heat dissipation coil 4 fixed to the side wall of the first fixed cylinder 3. A water replenishment tank 7 is fixed to the side wall of the first water tank 2. A first connecting block is fixed to the inner wall of the first water tank 2. A first inner tank 8 is fixed to one end of the first connecting block near the center of the first water tank 2. A second connecting block is fixed to the inner wall of the first inner tank 8. A second inner tank 11 is fixed to one end of the second connecting block near the center of the first inner tank 8. A plurality of electric heating rods 12 are fixed to the bottom surface of the inner wall of the second inner tank 11. A second water tank 13 is fixed to the center of the bottom surface of the inner wall of the second inner tank 11. A lower fixed pipe 14 is fixedly connected through the lower end of the second water tank 13. The lower end of the lower fixed pipe 14 passes through the lower end of the second inner tank 11 and extends to the bottom of the second inner tank 11.

[0029] The support frame 1 is equipped with a circulation mechanism. The outlet end of the circulation mechanism is connected to the inlet end of the lower fixed pipe 14. At least two hot water pipes 23 are fixedly connected to one end through the inner wall of the first water tank 2. The other end of the hot water pipes 23 passes through the first fixed cylinder 3 and is fixed to the inside of the heat dissipation coil 4.

[0030] The upper end of the second inner tank 11 is fixedly connected to the second fixed cylinder 9, the upper end of the second fixed cylinder 9 is fixedly connected to the upper end of the inner wall of the first inner tank 8, and the side wall of the second fixed cylinder 9 is provided with a through groove 10.

[0031] A water storage chamber 16 is formed between the first inner tank 8 and the first water tank 2, and a heat storage chamber 17 is formed between the first inner tank 8 and the second inner tank 11. An upper fixed pipe 15 is fixedly connected to the upper end of the second water tank 13. The upper end of the upper fixed pipe 15 passes through the first inner tank 8 and extends into the water storage chamber 16. The outlet pipe of the heat dissipation coil 4 is connected to the inlet of the water supply tank 7.

[0032] The heat storage chamber 17 is filled with liquid sodium or composite phase change material. When in use, the circulation mechanism is activated to draw out the water in the water replenishment tank 7 and transport it through the pipeline to the lower fixed pipe 14, and then into the second water tank 13. The electric heating rod 12 is turned on to heat the water in the second water tank 13. The heated water enters the water storage chamber 16 through the upper fixed pipe 15.

[0033] Meanwhile, the heat storage cavity 17 between the second inner tank 11 and the first inner tank 8 was originally filled with heat storage medium. Under the action of heat convection, it flows through the connecting groove 10 on the side wall of the second fixed cylinder 9. During the flow, the heat of the heat storage medium is transferred to the water storage cavity 16 through the walls of the second inner tank 11 and the first inner tank 8, so as to replenish the heat of the water in the water storage cavity 16.

[0034] The heated water in the water storage chamber 16 is transported to the radiator coil 4 through the hot water pipe 23. The radiator coil 4 heats up and provides heating. The water that has not been completely cooled after heat dissipation flows back to the water supply tank 7 through the pipe, realizing the recycling of water.

[0035] Throughout the process, the heat storage medium in the heat storage chamber 17 continuously flows and exchanges heat through the connecting channel 10. The water in the water storage chamber 16 forms convection under the action of related structures, which improves the heat exchange efficiency. When the water in the water replenishment tank 7 is insufficient, water can be replenished to the water replenishment tank 7 through the water replenishment pipe 18 to ensure the continuous and stable operation of the device.

[0036] Please see Figure 1 and Figure 6 In this embodiment, the circulation mechanism includes a support block fixed to the inner wall of the support frame 1 and a pump body 20 fixed to the upper end of the support block. The pump body 20 has a pump pipe 22 fixed to one end of its pumping end, and the other end of the pump pipe 22 is fixed to the outlet end of the water supply tank 7. The pump body 20 has an outlet pipe 21 fixed to one end of its outlet end, and the other end of the outlet pipe 21 passes through the first water tank 2 and the first inner tank 8 and is fixed to the inlet end of the lower fixed pipe 14. The pump body 20 provides power to pump water from the water supply tank 7 through the pump pipe 22 and deliver it to the lower fixed pipe 14 through the outlet pipe 21. This can provide continuous power for water circulation. Combined with the thermal convection of the medium in the heat storage chamber 17, it can enhance the flow of the medium and the convection of the water, increase the heat exchange per unit time, and avoid the heating lag problem caused by the large water capacity of traditional boilers.

[0037] Please see Figure 1 and Figure 5 In this embodiment, one end of a connecting pipe 5 is fixedly connected to the lower end of the first inner tank 8. The other end of the connecting pipe 5 passes through the support frame 1, the first water tank 2, the first inner tank 8 and the second inner tank 11 in sequence and extends into the interior of the second inner tank 11. The connecting pipe 5 can realize the flow of medium or water between related cavities, which helps to form a circulation. In conjunction with the structure of the heat storage cavity 17 and the water storage cavity 16, it can reduce heat loss and provide a channel for the cascade utilization of thermal energy, thereby improving thermal efficiency.

[0038] Please see Figure 1 and Figure 5 In this embodiment, a first valve body 6 is provided on the connecting pipe 5. The first valve body 6 can control the opening and closing of the connecting pipe 5 and the flow rate. The connecting pipe 5 can guide the flow of the heat storage medium.

[0039] Please see Figure 1 and Figure 2 In this embodiment, the lower end of the first inner tank 8 is hemispherical. The hemispherical lower end of the first inner tank 8 can guide the heat storage medium to gather at the bottom. It can also work with the slight disturbance generated when the outlet pipe 21 of the circulation mechanism replenishes water to the second water tank 13, thereby enhancing the heat exchange efficiency of the medium flow, reducing heat loss, and improving the heat exchange effect.

[0040] Please see Figure 1 and Figure 2 In this embodiment, the portion of the connecting pipe 5 located at the lower end of the first inner tank 8 is coaxially arranged with the lower fixed pipe 14. This coaxial arrangement allows the medium or water in the connecting pipe 5 and the lower fixed pipe 14 to flow more smoothly, reducing flow resistance, enhancing the convection effect of the medium and water, increasing the heat exchange per unit time, and thus improving thermal efficiency.

[0041] Please see Figure 1 and Figure 2 In this embodiment, the upper fixed pipe 15 and the first inner tank 8 are coaxially arranged, which enables the water sprayed into the water storage chamber 16 by the upper fixed pipe 15 to form a more uniform convection. This, combined with the turbulent flow formed by the medium in the heat storage chamber 17 through the connecting groove 10, greatly increases the heat exchange per unit time and ensures stable heating.

[0042] Please see Figure 1 and Figure 4 In this embodiment, a water supply pipe 18 is fixedly connected through the water supply tank 7. A second valve body 19 is provided on the water supply pipe 18. The water supply pipe 18 can replenish water to the water supply tank 7 as needed by opening the second valve body 19. With the continuous power of the circulation mechanism, the heating lag problem caused by the large water capacity of traditional boilers is avoided, and stable heating is achieved, while ensuring the continuity of water recycling.

[0043] Working principle: When in use, the pump body 20 in the circulation mechanism is started. The pump body 20 draws cold water from the water supply tank 7 through the water pumping pipe 22, and delivers it to the lower fixed pipe 14 through the water outlet pipe 21 and enters the second water tank 13. At this time, the electric heating rod 12 fixed to the bottom of the inner wall of the second inner tank 11 heats the heat storage medium in the second inner tank 11. Through heat conduction, the cold water in the second water tank 13 can be heated. The heated water enters the water storage chamber 16 through the upper fixed pipe 15.

[0044] Meanwhile, the high-temperature heat storage medium in the heat storage chamber 17 flows through the connecting groove 10 on the side wall of the second fixed cylinder 9 under the action of heat convection. The heat is transferred to the water storage chamber 16 through the walls of the second inner tank 11 and the first inner tank 8, which replenishes the heat of the water in the water storage chamber 16. The hemispherical design at the lower end of the first inner tank 8 guides the heat storage medium to gather at the bottom, and the slight disturbance generated when the water outlet pipe 21 replenishes water enhances the heat exchange efficiency of the medium flow.

[0045] The heated hot water in the water storage chamber 16 is transported to the radiator coil 4 through the hot water pipe 23 for heat dissipation and heating. The return water that has not been completely cooled after heat dissipation flows back to the water supply tank 7 through the pipe for recycling.

[0046] When the water level in the water tank 7 is insufficient, open the second valve body 19 on the water supply pipe 18 to replenish water to the water tank 7 through the water supply pipe 18.

[0047] In the initial stage of device startup or when a rapid increase in heating temperature is required, opening the first valve body 6 can accelerate the flow of the heat storage medium through the connecting pipe 5, shortening the time for the medium to reach a stable heat exchange state. Combined with the structure of the heat storage chamber 17 and the water storage chamber 16, it can improve thermal efficiency. Furthermore, the part of the connecting pipe 5 located at the lower end of the first inner tank 8 is coaxially arranged with the lower fixed pipe 14, and the upper fixed pipe 15 is coaxially arranged with the first inner tank 8, which can reduce flow resistance and enhance convection effect, ensuring stable heating of the device.
