[0025] See also Figure 1-5 , the utility model provides a technical solution: Example 1:

[0026] A hot air circulation device for a fermentation tank comprises a mounting box 1, a top cover 2, a tank body 7, a circulating fan 10 and a pressure tank 11. The top cover 2 is provided at the upper end of the tank body 7, the mounting box 1 is provided above the top cover 2, a heating wire 19 is provided inside the mounting box 1, the lower end of the mounting box 1 is connected to the circulating fan 10, the output end of the circulating fan 10 is provided with a heat exchange pipe 15 which passes through the top cover 2 and is located in a spiral shape inside the tank body 7 and the end of which passes through the mounting box 1, the heat exchange pipe 15 is located in the middle layer of the tank body 7, the upper end of the top cover 2 is provided with the pressure tank 11, the pressure tank 11 is connected to the mounting box 1 through a pipeline, and a control valve is provided inside the pipeline, temperature sensors 8 distributed equidistantly in the longitudinal direction are provided inside one end of the tank body 7, and hydraulic rods 3 are provided at both ends of the tank body 7.

[0027] A base 5 is provided at the lower end of the tank body 7, and the base 5 includes support legs distributed in a circular array on the sides of the tank body 7;

[0028] A discharge pipe 6 is provided at the lower end of the tank body 7, a valve is provided inside the discharge pipe 6, and a pressure relief valve 14 is provided at the upper end of the top cover 2;

[0029] A pressure sensor 9 is provided inside one end of the tank body 7, a pressure pump 12 is installed through one end of the pressure tank 11, a filter element 13 is provided at the suction end of the pressure pump 12, and a one-way valve is provided at the connection between the pressure tank 11 and the pressure pump 12;

[0030] In this embodiment, a temperature sensor 8 is used to detect the temperature of the material inside the tank body 7 in sections to ensure that the heat exchange operation is performed at an appropriate temperature. The pressure inside the tank body 7 is controlled by installing a pressure relief valve 14. The pressure is monitored and released in time with the help of a pressure sensor 9 to keep the system pressure stable and avoid unexpected situations. Through the opening and closing of the top cover 2, the design of the heat exchange pipe 15 and the operation of the circulating fan 10, the organic fertilizer is heated more evenly during the fermentation process, thereby improving the fermentation efficiency. By designing a reasonable heat exchange system and pressure control method, energy resources can be used more effectively, energy consumption can be reduced, and the operating efficiency of the system can be improved, meeting the requirements of energy conservation and environmental protection.

[0031] Example 2:

[0032] The outer wall of the tank body 7 is provided with a motor 4 distributed in a circular array, and a rotating shaft 17 is provided at the output end of the motor 4. A bearing 20 distributed in a circular array is embedded and installed inside the tank body 7. The rotating shaft 17 is rotatably inserted into the bearing 20. One end of the rotating shaft 17 located inside the tank body 7 is provided with a stirring rod 18 located inside the side of the tank body 7 and distributed in a circular array;

[0033] The outer wall of the top cover 2 is sleeved with a side ring 16, and the upper end of the hydraulic rod 3 is provided with a mounting plate 21. The upper end of the mounting plate 21 is embedded with a second bearing 22. The upper end of the second bearing 22 is internally rotatably plugged with a mounting shaft 23. The upper end of the mounting shaft 23 is provided with a clamping plate 24.

[0034] In this embodiment, the motor 4 drives the rotating shaft 17 and the stirring rod 18 to stir and mix the organic fertilizer inside the tank body 7, ensuring that the organic fertilizer is heated evenly, improving the heat conduction efficiency, and optimizing the fermentation process. The top cover 2 is conveniently moved longitudinally by the cooperation of the hydraulic rod 3 with the mounting plate 21 and the card plate 24, and the moving top cover 2 drives the heat exchange tube 15 to move out of the tank body 7, which facilitates the maintenance and cleaning of the inside of the tank body 7 and reduces labor.

[0035] Working principle: The hydraulic rod 3 drives the mounting plate 21 to lift, and the mounting plate 21 is located at the lower end of the side ring 16. The lifting force acts on the top cover 2, and the top cover 2 opens to transport the material into the tank body 7 and rotate the card plate 24. The card plate 24 is supported by the bearing 22 for rotation, and the upper end of the mounting plate 21 rotates. When the side ring 16 rotates, the side ring 16 is clamped between the mounting plate 21 and the card plate 24, and then the longitudinal push and pull force acts on the top cover 2, and the top cover 2 closes the upper end of the tank body 7. The organic fertilizer is fermented inside the tank body 7. During the fermentation process, the pipeline connecting the pressure tank 11 and the inside of the mounting box 1 is opened, and the pressure tank 11 transports pressure to the inside of the mounting box 1. Then the pipeline is closed, and the heating wire 19 heats the input gas. The circulating fan 10 sucks the gas inside the mounting box 1 and transports it to the inside of the heat exchange tube 15. The heat exchange tube 15 is heated by the hot gas, and then the organic fertilizer inside the tank body 7 is heated by the hot gas. The middle layer radiates to the inner layer and the outer side, and the temperature sensor 8 detects the temperature of the internal material at different heights of the tank body 7 in sections. When the temperature is reached, the heat exchange ends, and the heat exchanged gas flows back to the installation box 1. It is worth noting that the installation box 1 needs to be installed with a pressure relief valve 14 to control the pressure inside the installation box 1. After the inside of the tank body 7 is heated, the pressure rises accordingly. The internal pressure of the tank body 7 is detected by the pressure sensor 9, and the pressure is appropriately released through the pressure relief valve 14. When the compressed gas inside the tank body 7 is insufficient, the pressure pump 12 sucks the external gas. After the gas is filtered through the filter element 13, it is compressed and enters the pressure tank 11 for pre-storage. During the heat exchange of the organic fertilizer, the motor 4 operates, driving the shaft 17 to rotate inside the bearing, and driving the stirring rod 18 inside the tank body 7 to stir the organic fertilizer, thereby mixing the organic fertilizer longitudinally. The heat conduction effect of the heat exchange process is improved, thereby improving the heat exchange effect of the fermented organic fertilizer.
