Description

Technical Field

[0001] The utility model relates to the technical field of heating equipment, in particular to a heating device, specifically an electric energy storage heating device. Background Art

[0002] With the improvement of people's living standards and the requirements for the comfort of work and living environments, the consumption of electric energy and the like has increased significantly, resulting in problems such as excessive energy consumption, increased environmental pollution, excessive peak-valley differences in power grid loads, and severe power shortages during peak loads. With the continuous development of the economy and the continuous improvement of people's living standards, the proportion of building energy consumption will further increase. The electric heat storage technology is an important technology for improving energy utilization efficiency and protecting the environment, and is also an effective way commonly used to alleviate the mismatch between the energy supply and demand sides in terms of time, intensity, and location.

[0003] As a specific application of the electric heat storage technology, the electric energy storage heating device uses a high-density, high specific heat, high temperature resistance, and high pressure resistance magnesium-based heat storage body as an energy storage unit. Through PLC, microcomputer, and network control, it uses cheap electricity during the night valley period, heats the heat storage body through a special electric heating tube to maintain it at a high temperature of up to 750°C, and conducts heat insulation through a multi-layer reinforced heat insulation layer; during the peak power supply stage, heating is stopped, and the stored heat is evenly released according to the parameters set by the control system. The released heat is converted into hot water or steam in the furnace through an efficient heat exchanger for users to use throughout the day, so as to achieve the purpose of both comfortable heating and cost savings. It has extremely high application value especially in wind power and photovoltaic power areas.

[0004] In the existing electric energy storage heating devices, the heat storage bodies are all fixedly arranged. Some electric energy storage heating devices adopt an installation arrangement method in which multiple heat storage bodies are closely attached. The hot air passes through from one side of all the heat storage bodies to absorb the heat released by the heat storage bodies. During use, the heat released by the heat storage bodies is slow, and the heating efficiency is low; in some other electric energy storage heating devices, multiple heat storage bodies are arranged at equal distances. The hot air can pass through between the multiple heat storage bodies. Although it improves the heating efficiency during use, this arrangement will cause heat loss of the heat storage bodies when the heat storage bodies are electrified and heated, resulting in increased energy consumption.

[0021] Such as Figure 1-2As shown in the figure, the present utility model provides an electric energy storage heating device, which includes an adiabatic box body 1 having a heat storage cavity 11 and a plurality of heat storage bodies 2 arranged in the heat storage cavity 11. A heating pipe 3 penetrates through the middle of the heat storage body 2. The plurality of heat storage bodies 2 are movably installed on an adjusting component in the heat storage cavity 11. When the heating pipe 3 is energized to heat and store energy in the heat storage body 2, the adjusting component adjusts the plurality of heat storage bodies 2 to closely fit each other, forming a first air duct 12 between the plurality of heat storage bodies 2 and the inner wall of the adiabatic box body 1. A circulating fan 4 is installed at the air inlet of the first air duct 12. When the heat storage body 2 releases heat, the adjusting component adjusts the plurality of heat storage bodies 2 to separate from each other, forming a second air duct 13 between the plurality of heat storage bodies 2. The circulating fan 4 drives the air flow to pass through the heat storage body 2 along the first air duct 12 and the second air duct 13, fully absorbing the heat on the heat storage body 2.

[0022] The adiabatic box body 1 further has a heat exchange cavity 14, and the heat exchange cavity 14 is respectively communicated with the air inlet and the air outlet of the first air duct 12. A U-shaped heat exchange pipe 5 is arranged in the heat exchange cavity 14. The U-shaped heat exchange pipe 5 has a water inlet 51 and a water outlet 52, so that the high-temperature hot air that fully absorbs the heat on the heat storage body 2 enters the heat exchange cavity 14 from the air outlet of the first air duct 12 to heat the cold water entering the U-shaped heat exchange pipe 5 from the water inlet 51 and then discharges it from the water outlet 52 for heating.

[0023] A high-strength bearing plate 15 is arranged between the heat exchange cavity 14 and the heat storage cavity 11 to bear the plurality of heat storage bodies 2. The adiabatic box body 1 adopts a high-temperature nano-microporous heat insulation structure, and a load-bearing base is arranged at the bottom of the adiabatic box body 1.

[0024] The plurality of heat storage bodies 2 are respectively provided with threaded holes with different helix directions and pitches. As Figure 3-4 shown, the adjusting component includes a segmented bolt 6 that penetrates through the top wall of the adiabatic box body 1 and is rotationally connected to the bearing plate 15. The bolt 6 has multiple sections of threads that respectively engage with the threaded holes on the plurality of heat storage bodies 2, so as to rotate the bolt 6 to adjust the plurality of heat storage bodies 2 to fit towards the middle / to separate towards both sides.

[0025] Four heat storage bodies 2 are provided. The middle heat storage body one 21 and the heat storage body two 22 have threaded holes with opposite helix directions and the same pitch. The heat storage body three 23 on one side of the heat storage body one 21 has a threaded hole with the same helix direction as the heat storage body one 21 and a double pitch. The heat storage body four 24 on one side of the heat storage body two 22 has a threaded hole with the same helix direction as the heat storage body two 22 and a double pitch. As another implementation manner, a heat storage body five 25 is further arranged between the heat storage body one 21 and the heat storage body two 22. The heat storage body five 25 is provided with a through hole with an annular groove on the inner wall. The bolt 6 has an annular protrusion adapted to the annular groove to limit the position of the heat storage body five 25 when the bolt 6 rotates. One end of the bolt 6 has a bolt head 61 that fits against the top surface of the adiabatic box body 1, and the other end has a limiting plate 62 that fits against the bottom surface of the bearing plate 15 to limit the axial movement of the bolt 6.

At this time, the heating tube 3 is powered on to heat and store energy for the heat storage body 2, reducing the heat loss of the heat storage body 2 and lowering the energy consumption. Then, during the peak stage of day power supply, the power supply of the heating tube 3 is disconnected to stop heating. When heating is required, by rotating the bolt 6 backward, the fifth heat storage body 25 remains stationary, and the first heat storage body 21 and the third heat storage body 23, and the second heat storage body 22 and the fourth heat storage body 24 move and separate in the two sides direction of the fifth heat storage body 25 under the action of thread engagement, and the moving distances of the third heat storage body 23 and the fourth heat storage body 24 are respectively twice that of the first heat storage body 21 and the second heat storage body 22, so as to form a second air duct 13 communicating with the first air duct 12 between multiple heat storage bodies 2. At this time, the circulation fan 4 is turned on, and the circulation fan 4 drives the air flow to pass through the heat storage body 2 along the first air duct 12 and the second air duct 13, fully absorbing the heat on the heat storage body 2, and forming high-temperature hot air to enter the heat exchange cavity 14 from the air outlet of the first air duct 12, heating the cold water entering the U-shaped heat exchange tube 5 from the water inlet 51 and discharging it from the water outlet 52 for heating, significantly improving the heating efficiency and effect when the heating device is in use.
