The specific embodiment

In Fig. 1-Fig. 4, the title that label is corresponding: 1-barn main body, 2-warm-air pipe, 3-flash vessel, 4-recovery tube, 5-combustion chamber, 6-combustion chamber, 7-motor, 8-capacity reducing device, 9-turning cylinder, 10-flabellum, 11-motor, 12-arranges warm window, 13-thermometer

Below in conjunction with accompanying drawing, the utility model will be further described.

Embodiment mono-, the position between warm-air pipe 2, motor 7, barn main body 1, recovery tube 4 and combustion chamber 5 four and connected mode are as shown in Figure 1; The position of recovery tube 4 in barn main body 1 and connected mode are as shown in Figure 3; Outside connection between combustion chamber 5, motor 7, warm-air pipe 2, recovery tube 3, barn main body 1 and the installation site of thermometer 13 are as shown in Figure 4; The barn main body 1 of the present embodiment, the material of combustion chamber 5 are the rock cotton board with heat insulation function, and its thickness is 70 millimeters, and the diameter of warm-air pipe 2, recovery tube 4 is the hollow stainless steel tube of 200 millimeters.The length of barn main body 1 is respectively 5 meters, 3.5 meters, 2.4 meters, and the length of combustion chamber 5 is respectively 1 meter, 1 meter, 2.2 meters, and the shape of smoke exhaust pipe 2, recovery tube 4 can be that circle can be also oval, can also be other shapes.

Comburant is in 6 li of burnings of combustion chamber, starter motor 7, after flowing to flash vessel 3 from the warm-air pipe 2 of 5 bottoms, combustion chamber, the hot blast producing enters in barn main body 1, at this moment starter motor 11, turning cylinder 9 rotates, group flabellum 10 is evenly delivered to the four directions in barn main body 1 by hot blast, under the twitch force of motor 7, recovery tube 4 is again the sirocco reclamation in barn main body 1, the top of flow into combustor 5 after capacity reducing device 8, after 5 li of combustion chambers are heated from top to bottom, from warm-air pipe 2, flow to barn again, so recycle hot blast, just reach the object of saving heat energy.
