The invention discloses a draught fan with functions of air suction and paper shredding. The draught fan comprises a base, a centrifuge casing, an impeller mechanism, a tapered air inlet passage, a fixed bracket, a rotating shaft cooler, a driving shaft and a driving motor; fixed blades are mounted on a blade mounting flange; movable blades are arranged on the side, close to the fixed blades, of the impeller mechanism. According to the draught fan with the functions of air suction and paper shredding, the fixed blades and the movable blades disposed close to the fixed blades are adopted for achieving shearing type smashing of waste paper, the waste paper can be shredded during pneumatic transportation, the two functions are achieved simultaneously, and not only is the structure simple, butalso the cost of recycling the waste paper is reduced. 本发明创造公开了种吸风碎纸风机，包括底座、离心机壳、叶轮机构、锥形进风通道、固定支架、转轴冷却器、驱动轴以及驱动电机；在刀片安装法兰上安装有固定刀片；在叶轮机构上且靠近固定刀片的侧设有活动刀片。该吸风碎纸风机利用固定刀片以及靠近设置的活动刀片实现了剪切式的废纸粉碎，能够在进行废纸风力运输的过程中进行切碎，使两种功能同步完成，不仅结构简单
