effect is preferable；(7) by the way that several arc panels are arranged in the disk of spreading disk 306 307 form several spreading channels 308, so that raw material can be thrown away from different spreading channels, be spilt more in spreading disk rotation Uniformly, so that the raw material stirring and mixing effect in barrel is more preferable；Quantity limitation to arc panel, can preferably form suitable number The spreading channel of amount, convenient for preferably being distributed raw material, so that it is more preferable to spill mixed effect；By arc panel on spreading disk The hand of spiral is set as the rotation direction with agitating shaft on the contrary, also for the rotation direction for adapting to agitating shaft, so that raw material exists In the case where generating minimum drag to agitating shaft, by it is a kind of naturally in a manner of throw away and spill out, design rationally, spill effect compared with It is good；By the way that stirring rod 217 is arranged on helical mixing blade, the contact position of stirring rod and helical mixing blade 304 is perpendicular, makes Helical mixing blade is obtained while upward helical feed raw material, plays certain stirring, top spills and internal two kinds of stirring Mode carries out simultaneously, guarantees the good mixing of raw material in barrel；Setting lower end for stirring rod is vertical bar column, and upper end is opening The structure of arc-shaped preferable mixing effect is guaranteed with a kind of relatively simple structure, it is easy to use；(8) by main air hose Three mounting holes 407 are set between adjacent annular averaging wind pipe 402 again on 401, it is equal equipped with gourd shape at mounting hole Tuyere 406 done sufficient utilization to the surface of main air hose, so that there is not external wind at dead angle in barrel, Have air circulation in barrel everywhere, and by between mounting hole setting position and setting angle all done strict regulations, be exactly In order to guarantee optimal air-out effect, design relatively reasonable；Round and smooth excessive throat structure 408 enables wind smoothly to blow out Also there is biggish power simultaneously, so that the wind of tuyere blowout more has intensity；Specific amount of setting, so that the cylindricality of barrel The annular averaging wind pipe 402 of equally spaced setting from top to bottom, guarantees airflow effects at partial inner wall；The air outlet of all equal tuyeres It is directed to the center of annular averaging wind pipe, being arranged on annular averaging wind pipe for angle is provided with enough equal tuyeres, guarantees Outlet air is uniform at annular averaging wind pipe；(9) polyimides has heat resistance, cold resistance, weatherability, electrical property and anti-flammability, makes The electric insulating effect for obtaining insulated ring is preferable, and service life is longer；The design of 501 structure of shell, so that air enters energy after shell It enough carries out buffering and wind speed is adjusted, air has heat source soft in the intracorporal good heating of shell, infrared heat lamp 515, safety The infrared heat lamp of higher feature, lower part can preheat in advance the air entered at heating tube, and the infrared of top adds Thermolamp also can carry out supplement
