1. dry the hot air tunnel drying plant of heat exchange concurrent flow pipe for one kind, comprise workbench (9), the top of workbench (9) is provided with hot air tunnel (8), it is characterized in that:

  • in described workbench (9), be provided with the filtering pressure reducing valve (1) that pipeline (3) connects successively, intelligent pressure controller (2), industry heat gun (4), industry heat gun (4) connects hot blast cutter (10) by pipeline (6), on described hot blast cutter (10) has, lower two groups, lay respectively at the upper of the heat exchange concurrent flow pipe outlet side of workbench (9) top hot air tunnel (8), lower two ends, on, lower two groups of hot blast cutter (10) edges of a knife point to the midline position of hot air tunnel (8) respectively, contrary with product direction of advance, guide wheel (11) is also provided with in the side of hot blast cutter (10),Be provided with heated at constant temperature controller (5) in described workbench (9), make hot blast temperature rise to 100 DEG C, to mate the normal extrusion speed of heat exchange concurrent flow pipe;

    15-20 degree angles are become between two knife faces of described hot blast cutter (10);

    Center line between two knife faces of described hot blast cutter (10) and the midline position of hot air tunnel (8) are 30-35 spend angle, hot blast blows to the surface of the heat exchange concurrent flow pipe in hot air tunnel (8) by hot blast cutter, heat exchange concurrent flow pipe under the control of guide wheel (11) with hot air flow to antikinesis, dried by heated-air drying.
