When the thermal insulation material drying device works, the flow process of the thermal insulation material is as follows: the thermal insulation material enters from the thermal insulation material feed hopper 5 and falls onto the first drying plate A of the thermal insulation material, and the thermal insulation material shovel above the first drying plate A of the thermal insulation material Under the action of rotation and stirring, it continuously advances to the first thermal insulation material discharge port 1, and then falls onto the second thermal insulation material drying plate B. The material shovel moves to the edge of the second drying plate B of the heat-insulating material under the rotation stirring of the material shovel, and falls onto the third drying plate C of the heat-insulating material.

Similarly, the thermal insulation material on the third drying plate C of the thermal insulation material falls from the third thermal insulation material blanking port 2 onto the spinner under the action of the thermal insulation material shovel thereon, and the thermal insulation material on the spinner 27 is thrown out by centrifugal force Impact on the inner surface of the thermal insulation material heating sleeve 120 to carry out the final stage of drying; the flow process of the steam is: the external heating steam source enters from the steam inlet pipe 25 of the third drying plate C of the thermal insulation material, and heats the third drying plate of the thermal insulation material The thermal insulation material on C is heated, and part of the steam evaporated by the heated thermal insulation material rises from the gap between the second thermal insulation material drying plate B and the thermal insulation material drying device housing 111 and enters the funnel shell 14, and then enters the first One thermal insulation material evaporation steam inlet 117 is used as the heating steam of the first drying tray A of the thermal insulation material, and another part enters from the second thermal insulation material evaporation steam inlet 118 as the heating steam of the second drying tray B of the thermal insulation material, and the second thermal insulation material drying tray B is used as the heating steam.

The thermal insulation material drying device is ingeniously designed. It not only makes full use of the steam generated after the thermal insulation material is heated to reheat the upper-level thermal insulation material, but also changes the heat from the bottom surface of the drying plate in the past.
