[0024] Refer to the instruction manual Figure 1-5 The utility model provides a solid heat storage device with adjustable air outlet temperature, comprising a heat storage component, the outside of which is provided with a functional component for adjusting the air outlet temperature;

[0025] like Figure 1-5 As shown, the functional component includes a transfer tank 1 arranged on one side of the heat storage component, and a spiral heat exchange tube 2 is provided inside the transfer tank 1. The front side of the bottom end of the heat exchange tube 2 is fixedly connected to the output tube 3, and the front end of the output tube 3 passes through the transfer tank 1 and extends to the outside of the transfer tank 1; the top end of the heat exchange tube 2 passes through the transfer tank 1 and is fixedly connected to the air supply tube 4, and a fan 5 is installed inside the air supply tube 4, and a linkage shaft 6 is installed at the bottom of the output shaft of the fan 5, and the bottom end of the linkage shaft 6 passes through the air supply tube 4 and extends to the inside of the transfer tank 1; a movable shaft 7 movably connected by a bearing is installed inside the transfer tank 1, the movable shaft 7 is arranged inside the heat exchange tube 2, and a plurality of spaced-apart turbulent blades 8 are installed on both sides of the movable shaft 7, and the bottom end of the linkage shaft 6 is fixed to the top of the movable shaft 7.

[0026] Specifically, the external air is transported to the heat exchange tube 2 for heat exchange through the fan 5. At the same time, the movable shaft 7 can drive the turbulent blades 8 to stir the hot air through the connection between the linkage shaft 6 and the fan 5, so that the hot air can be fully in contact with the heat exchange tube 2, thereby improving the heat transfer efficiency and the heat exchange efficiency, and thereby achieving the effect of temperature control of the hot air. The external air does not directly contact the hot air, thereby preventing impurities in the external air from contaminating the transfer tank 1.

[0027] like Figure 1-3 As shown, the heat storage assembly includes a heat storage furnace 9, a heat storage body 10, an air inlet pipe 11 and an air outlet pipe 12. The heat storage body 10 is arranged inside the heat storage furnace 9, and the air outlet pipe 12 is arranged on the side of the bottom end of the heat storage furnace 9 close to the transfer tank 1, and the end of the air outlet pipe 12 away from the heat storage furnace 9 is fixedly connected to the transfer tank 1, and the air inlet pipe 11 is arranged on the side of the top end of the heat storage furnace 9 away from the transfer tank 1. Through the coordinated use of the heat storage furnace 9, the heat storage body 10, the air inlet pipe 11 and the air outlet pipe 12, heat energy storage treatment can be carried out.

[0028] like Figure 1-4 As shown, a temperature sensor 13 is installed on the top of the transfer tank 1, and the detection end of the temperature sensor 13 extends to the inside of the transfer tank 1. A controller 14 installed on the top of the transfer tank 1 is provided on the front side of the temperature sensor 13. The temperature inside the transfer tank 1 is monitored by the temperature sensor 13, and the temperature sensor 13, the solenoid valve 19 and the fan 5 of the utility model are opened and closed by the controller 14.

[0029] like Figure 2 and 3 As shown, an air pump 15 is installed outside the air outlet pipe 12 for conveying high-temperature gas into the transfer tank 1. The air pump 15 conveys the hot gas in the heat storage furnace 9 through the air outlet pipe 12 to the interior of the transfer tank 1 for temperature control.

[0030] like Figure 1-4 As shown, a support ring 16 is provided on the outside of the top end of the air supply pipe 4, and support members 17 are installed on the front and rear sides of the support ring 16. The bottom of the end of the support member 17 away from the support ring 16 is fixed to the top of the transfer tank 1. The air supply pipe 4 is supported by the support ring 16 and the support member 17 thereon, thereby ensuring the stability of the air supply pipe 4 and preventing the air supply pipe 4 from tilting and collapsing.

[0033] The operator operates the controller 14 to start the air pump 15. The air pump 15 transports the gas heated by the heat storage body 10 in the heat storage furnace 9 to the interior of the transfer tank 1 through the air outlet pipe. At the same time, the fan 5 is started to transport the outside air through the air supply pipe 4 to the interior of the heat exchange tube 2. The spiral heat exchange tube 2 extends the air flow path, allowing the outside air to fully absorb the heat on the heat exchange tube 2, achieving effective heat absorption and heat exchange effects. The hot air does not come into direct contact with the outside air, thereby preventing impurities such as dust from entering the interior of the transfer tank 1 and causing pollution.

[0034] The fan 5 drives the movable shaft 7 and the plurality of spoiler blades 8 on the transfer tank 1 to rotate by means of the linkage shaft 6, thereby accelerating the circulation of the hot air, so that the hot air can fully contact the heat exchange tube 2, and improve the heat exchange efficiency and heat transfer efficiency;

[0035] At the same time, the temperature in the transfer tank 1 is monitored by means of the temperature sensor 13 . When the temperature reaches a set value, the controller 14 opens the solenoid valve 19 and then discharges the hot gas in the transfer tank 1 through the outlet pipe 18 .

[0036] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
