As shown in fig. 1 and 2, the two sets of double-layer pipe elements 3 comprise a T-pipe 31 and a straight pipe 32; one end of a cross beam of the T-shaped pipe 31 is fixedly connected with the heat preservation shell 2, and a vertical beam port of the T-shaped pipe 31 is used for feeding and discharging heating materials; the straight-through pipe 32 is positioned inside the cross beam of the T-shaped pipe 31 and is installed through a sealing piece; one end of the straight-through pipe 32 penetrates through the side wall of the heat preservation shell 2 to be fixedly connected with the shell 1, and one end of the straight-through pipe 32, which is far away from the heat preservation shell 2, is used for feeding and discharging materials. The T-shaped pipe 31 on one side enters the heat-preserving shell 2 with heated air or liquid, and then flows out from the vertical beam port of the T-shaped pipe 31 on the other side, so that the inside of the shell 1 is always in a constant temperature state; the gear pump inside the shell 1 works, so that the negative pressure at the port of the straight through pipe 32 on one side generates suction to suck materials into the working cavity 111, and then the materials are guided out from the straight through pipe 32 on the other side.
