The carrier pipe is fixed on the fixed frame, thermal insulation cotton is arranged on the periphery of the heat carrier pipe, and a metal mask is arranged on the outer side of the thermal insulation cotton, and the metal mask is fixed on the bracket of the screw conveyor shell.

In the present invention, a material inlet is provided at the left end of the cover, and an inspection hole is provided at the right end; a material outlet is provided at the right bottom of the screw conveyor shell.

Compared with the prior art, the present invention has the following advantages:

The structure of the invention is simple, compact and reasonable; when the heat carrier flows in from the inlet to the outlet of the heat carrier pipe, due to the close contact between the heat carrier pipe and the screw conveyor shell, and materials for heat exchange to realize heat preservation, heating and cooling of materials; the use of heat preservation cotton can improve heat exchange efficiency and change the temperature and flow of heat carrier, which can meet the needs of different processes such as heat preservation, heating and cooling, making it The temperature of the material during the conveying process can be effectively controlled, and the anti-sticking property can be improved.
