The working principle of the solid heat storage and supply device is that the heating pipe 7 heats the heat storage brick 11 in the valley electricity price period, the fan 1 circulates air in the air duct, the heating pipe 7 and the heat storage brick 11 heat the air, the hot air transfers the heat of the air to water when flowing through the heat exchanger 16, the water supply pipe 18, the water return pipe 21 and the heat supply circulating water system form a closed loop, and the circulating water system sends the hot water to the building needing heat supply. And when the temperature of the heat storage bricks 11 is reduced to a set value or reaches the valley electricity price period, the heat storage bricks 11 are heated again by the heating pipes 7, and the solid heat storage and supply device works in a circulating mode every day in the heat supply season.

The specific working process is that when the air-cooled heat-accumulating fan works, a water supply pipe 18 and a water return pipe 21 are firstly connected to a water circulation system for supplying heat, a heating pipe 7 and a fan 1 are connected with a power supply, when the heating pipe 7 is electrified to heat, the heat-accumulating bricks 11 are heated, after the heat-accumulating bricks 11 are heated, a heat-insulating layer 9 can keep the heat of the heat-accumulating bricks 11 to be dissipated as little as possible, the two fans 1 symmetrically arranged at the front end of a base 5 are reversely turned, the positions of the air outlets of the two fans are close to the middle of the base 5, the air outlets of two fan covers 2 symmetrically arranged are connected to a low-temperature air port 4, when the fan 1 works, air is blown into a front air duct 8 from the fan covers 2 through the low-temperature air port 4, air pressure is formed in the front air duct 8, the air flows into a rear air duct 14 through ventilation grooves 12 on the heat-accumulating bricks, the heat dissipation speed of each layer of heat storage bricks 11 is close, the temperature of each layer of heat storage bricks 11 is kept close all the time, the temperature difference between each layer of heat storage bricks 11 and air is close to reduce the energy loss in the heat exchange process of the heat storage bricks 11 and the air, meanwhile, the service lives of the heat storage bricks 11 and the heating pipes 7 are close to be consistent, the early damage of the local heat storage bricks 11 and the heating pipes 7 due to overheating is avoided, the air flowing through the ventilation groove 12 is heated by the heat storage bricks 11 and the heating pipes 7 and then flows into the rear air duct 14, the hot air enters the base air chamber 17 through the high-temperature air opening 15 and then enters the heat exchanger 16 from the base air chamber 17, the heat exchanger 16 transfers the heat of the air to the circulating water, the circulating water system sends the hot water into the building needing to be heated, the air coming out of the heat exchanger 16 is cooled, the cooled air is sucked into the fan cover 2 by the fan 1 through the top-round, and entering the next circulation process. The corners of the air paths of the front air duct 8, the rear air duct 14 and the base air cavity 17 are designed to be smooth, so that the air flow resistance can be reduced, and the energy consumption of the fan 1 can be reduced. The fan 1 can adopt frequency conversion control to enable the rotating speed to be adjustable, the air flow rate of the fan 1 can be changed by changing the rotating speed, so that the flow of hot air flowing through the heat exchanger 16 is changed, the heat obtained by circulating water is also changed, and the purpose of controlling the water temperature is achieved, so that the requirement can be met by changing the temperature of the circulating water according to the environment temperature and the temperature required in a building. The sensor can be installed in the circulating water system, and the accurate control of the temperature in the heat supply building can be realized by combining the control system. The best energy-saving and environment-friendly effect is obtained. The heating pipe 7 is mainly used for heating in the valley electricity price period, and the purpose is to reduce the operation cost of the heating device. Generally, three temperature control nodes are arranged, wherein firstly, the starting temperature of the fan 1 is the starting temperature, namely, when the solid heat storage and supply device is started for the first time after being stopped working for a long time, the fan 1 is started after the temperature of the heat storage bricks 11 is heated to the specified temperature; secondly, the heating pipe 7 stops working at the temperature, namely the heating pipe 7 stops heating when the temperature of the heat storage bricks 11 is heated to the set maximum working temperature; thirdly, the heating pipe 7 works again, namely when the temperature of the heat accumulation bricks 11 after heat exchange is reduced to the set lowest value or reaches the valley electricity price time period, the heating pipe 7 heats the heat accumulation bricks 11 again. The working process of the solid heat storage and supply device can be automatically controlled by the temperature sensor and the automatic control system.
