Sinusoidal air flotation drying oven

I e (SCSF drying oven) is used to dry coated paper and has a very good practical effect. The dryer consists of a lower box and an upper box. The upper box and the lower box are rectangular boxes covered with thermal insulation layers. One side of the upper box and the lower box are connected by hinges, while the other side can be opened and closed by the action of the air cylinder. When open, the opening can reach 600 mm. Several groups of longitudinal air ducts are respectively fixed on the upper and lower boxes and are provided with a series of air-floating nozzles which are staggered up and down. Hot air enters the nozzle through the air inlet pipe and is directed obliquely at the paper surface at a speed of 40m / s. The upper and lower nozzles are arranged in the shape of a finished product, and when the paper sheet passes through the middle, it is floated by the air current and moves forward in a sinusoidal air-floating state, and the tension of the paper web is generally controlled within 5.5N / cm.
