Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
As shown in fig. 1-2, the lost foam formwork low-temperature energy-saving drying room comprises a drying room 1 (an inlet and outlet door 8 is arranged on the drying room), a drying control chamber 7 and a hot blast stove 5, wherein the drying control chamber 7 is arranged outside the drying room 1, the hot blast stove 5 is arranged in the drying control chamber, a hot blast pipeline 2 is arranged in the drying room, the hot blast stove 5 is connected with the hot blast pipeline 2 through a main air supply pipeline 3, and a blower 4 (generating negative pressure through the blower 4 and delivering hot air into the hot blast pipeline 2) is arranged in the main air supply pipeline; the drying control chamber is internally provided with a steam-water separation device 6 (the reference number 6-1 in figure 2 expresses a drain pipe of the steam-water separation device), the top of the drying room is provided with an air return pipeline 9, the air return pipeline 9 is connected to an inlet of the steam-water separation device 6 through an air filter 10, and an inlet of the steam-water separation device 6 is connected to the hot blast stove 5 through a pipeline.
In the technical scheme, the hot air temperature of the hot air furnace is set to be 30-45 ℃, so that the energy consumption can be further reduced on the basis of achieving the drying purpose.
In the above technical solution, the steam-water separation device 6 is preferably a cyclone steam-water separation device, or a water trap used in the existing vacuum drying system.
