[0021] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0022] like Figure 1-2 As shown, a heat recovery shaping machine includes a shaping module 20 and a high-temperature hot air blower 30. The shaping module 20 is used to shape the product to be shaped. High-temperature gas is required during the shaping process. The high-temperature gas enters the shaping module 20 through a hot air duct 21, and the used high-temperature gas is discharged through an exhaust gas duct 22. The shaping principle in the shaping module 20 adopts the existing technology.

[0023] The high-temperature hot air blower comprises a mounting frame 10 and a compressor 1, a condenser 2, a fan 3, an evaporator 4, a gas-liquid separator 5, a filter 6, an expansion valve 7, a circulation pump 8, a spray tower 9 and an air duct 11 arranged on the mounting frame 10.

[0024] The air inlet of the spray tower 9 is connected to the exhaust gas pipeline 22, and the water outlet of the spray tower 9 is connected to the water inlet of the circulation pump 8 through a pipeline. In the spray tower 9, the exhaust gas and water are heat exchanged. The water outlet of the circulation pump 8 is connected to the water inlet of the evaporator 4 through a pipeline, and the water outlet of the evaporator 4 is connected to the water inlet of the spray tower 9 through a pipeline. The water with a higher temperature enters the evaporator 4 from the spray tower 9 through the circulation pump 8, and the heat exchange is completed in the evaporator 4. The water with a lower temperature returns from the evaporator 4 to the spray tower 9.

[0025] The refrigerant outlet of the evaporator 4 is connected to the refrigerant inlet of the gas-liquid separator 5 through a pipeline, and the refrigerant outlet of the gas-liquid separator 5 is connected to the refrigerant inlet of the compressor 1 through a pipeline. The heated refrigerant gas coming out of the evaporator 4 enters the compressor 1 through the gas-liquid separator 5, and the gas-liquid separator 5 performs gas-liquid separation on the refrigerant to separate the liquid in the refrigerant.

[0026] The refrigerant outlet of the compressor 1 is connected to the refrigerant inlet of the condenser 2 through a pipe. The condenser 2 is arranged at the air inlet end of the air duct 11. The refrigerant outlet of the condenser 2 is connected to the refrigerant inlet of the evaporator 4 through a pipe. The compressor 1 is used to further heat the refrigerant to a required temperature. When the refrigerant enters the condenser 2, the refrigerant exchanges heat with the cold air in the air duct to heat the cold air. At the same time, the temperature of the refrigerant is reduced. The cooled refrigerant returns to the evaporator 4 and the compressor 1 for heating.

[0027] The fan 3 is disposed at the air outlet end of the air duct 11, and is used to move the air in the air duct 11 from the air inlet end to the air outlet end. The hot air duct 21 is connected to the air outlet end.

[0028] A filter 6 and an expansion valve 7 are sequentially arranged along the flow direction of the refrigerant on the pipeline connecting the refrigerant outlet of the condenser 2 and the refrigerant inlet of the evaporator 4. The filter 6 is used to filter impurities in the refrigerant, and the expansion valve 7 is used to throttle the medium-temperature and medium-pressure liquid refrigerant into low-temperature and low-pressure wet steam.
