Further, described windage device is welded on inner barrel inwall.
Further, be formed with the inner barrel discharging opening being connected with outer cylinder body on described inner barrel, inner barrel discharging opening front end is provided with one group and carries flitch, and rear end is provided with one group and returns to helical blade.
Further, described windage device is arranged at carrying between flitch and inner barrel discharging opening of inner barrel.
Further, described air cooling equipment is laid on feed box end face.
Further, the described dry-mixed mortar with windage device also includes with double back journey roller drying machine the air inducing dust pelletizing system that is connected in the exhaust air chamber of inner barrel end and is external in exhaust air chamber.
From above-mentioned, to description of the present utility model, compared with prior art, the utlity model has following beneficial effect:
1. by add a windage device in inner barrel, changed the distribution situation of negative pressure in drying roller, appropriateness minimizing the negative pressure in inner barrel, increased the negative pressure in outer cylinder body, make the negative pressure distribution of inner barrel and outer cylinder body more reasonable, thereby strengthened the intensity of cooling air, guaranteed the rear required drop temperature of sand oven dry;
2. windage device has increased the resistance between inner barrel and exhaust air chamber passage, has slowed down the speed of thermal current, makes thermal current and sand heat exchange more abundant, has improved the thermal efficiency, has reduced exhaust temperature, has reduced energy consumption;
3. windage device also can play the effect of guide, guarantees that material is by the direction motion of setting;
In a word, the utility model can strengthen the cooling effect of air cooling equipment, improve the thermal efficiency of drying thermal source, solved exhaust temperature that existing double back journey roller drying machine exists too high and dry after the slightly high defect of dry sand temperature, its reasonable in design, stable performance, technological process is smooth and easy, can effectively guarantee to dry the required moisture content of rear sand, the thermal efficiency is high, and energy-conserving and environment-protective.
