Controllable air guiding and blowing device for drying room

The utility model discloses a controllable guiding air supplying device for a hot air drying baking room, which is characterized in that a guiding air supplying device is arranged at the air discharging opening of a blower; the guiding air supplying device is provided with a circle transformation rectangular abnormity diameter changing casing and is inside provided with an adjustable diversion tongue plate; a diversion bending plate is arranged at the corner point of the side wall of the top of the baking room for matching with the guiding air supplying device so as to form smooth and fluent controllable attaching airflow. The utility model has the advantages that the adjustable diversion tongue plate can adjust the flow velocity, the direction and the flow rate of drying airflow so as to cause the drying airflow to conform to the requirement of drying process and enhance drying quality; the diversion bending plate is matched with the guiding air supplying device, the smooth and fluent controllable attaching airflow is formed, the air supplying resistance is lowered, the air supplying flow rate is enhanced, the drying period is shortened and the efficiency is enhanced. By using the utility model, an aluminum transverse partition which is positioned among an air supplying suspended ceiling, an air returning suspended ceiling and a plurality of blowers and adopted by the conventional baking room can be cancelled, the height of the baking room is lowered and the first investments are saved. The utility model adopts the high efficiency environmental protection type blower, reduces noise pollution, saves power consumption and lowers drying cost.
