The reinforcing rods 412 enhance the connection stability between the air pump 411 and the heating tank body 1, and reduce the risk of pipeline loosening or breakage caused by vibration or external factors.

[0027] Furthermore, connecting plates 612 are fixedly installed on both sides of the heat exchanger 6, and the connecting plates 612 are connected to the support frame 611 through a plurality of screws 613. The plurality of screws 613 improve the stability and safety of the heat exchanger 6, and at the same time facilitate disassembly and installation.

[0028] Furthermore, a temperature sensor 211 and a pressure sensor 212 are provided on the outer surface of the top end of the heating tank body 1.

Subsequently, the heating rod 311 starts to work, heating the quartz sand in the heating tank body 1, and at the same time removing impurities in the quartz sand through the pickling process. During the heating process, the hot air generated in the heating tank body 1 is extracted by the air pump 411 through the first connecting pipe 4. The electronic valve 5 controls the flow of the hot air to ensure that the hot air can smoothly enter the heat exchanger 6. In the heat exchanger 6, the cold water introduced through the water inlet 614 exchanges heat with the hot air extracted from the heating tank body 1. The heat energy in the hot air is transferred to the cold water to heat it. The hot water after heat exchange then flows into the storage tank 912 through the second connecting pipe 9 to achieve the storage of heat energy. When the quartz sand in the heating tank body 1 is completed with heating and pickling treatment, it is discharged through the discharge port at the bottom end of the heating tank body 1.
