Impeller rotary drum rotary-type steam box

The invention discloses an impeller rotary drum rotary-type steam box, which comprises at least one steam box single body, wherein the steam box single body comprises a box body; a steam groove is set inside the box body; a water chamber is set below the steam groove; a heating device is set on the bottom of the water chamber; an impeller is set inside the steam groove; a cloth containing cavity is set between two adjacent blades of the impeller; a cloth support device is set below the impeller; a roller and a cloth arranging device are set at an inlet side of the steam box above the impeller; and a cloth traction roller is set at an outlet side of the steam box above the impeller. According to the invention, under the loading of the intermittent rotation of the impeller, the steam box provided herein can be use for processing cylinder-shaped fabric with full width and also the fabrics are separated with segmentation by the blades of the impeller in the steam box; the slack degree of the fabric is high; and the fabrics between the adjacent blades will be displaced and become less crowded with the slow rotation of the impeller rotary drum, thus the steam effect is even and thorough.
