筒体旋转风刀自动清扫装置的研制与应用

Development and Application of Automatic Pneumatic Cylinder Cleaner

为解决烟草制丝线滚筒类设备中普遍存在的筒内粘料问题,根据高速气流的空气动力学原理,研制了筒体旋转风刀自动清扫装置。该装置采用小型高压风机做动力源,将高速气流转化成旋转的风刀,作用在筒体内壁上,对易形成粘料的筒壁区域进行喷吹清扫,防止粘料发生。应用效果表明,叶丝加料机采用该装置后,筒壁粘料量平均由每班次40.6 kg减少为3.3 kg。装置结构简单,能够有效地对筒壁和耙钉进行清扫,并具有自清洁功能,较好地解决了筒体内壁的粘料问题。

To remove the tobacco dust buildup on wall of cylindrical equipment in tobacco primary processing line, an automatic pneumatic cleaner was developed on the basis of aerodynamic principle of high speed air stream. From a small high-pressure fan, the high speed air stream injected on the inner wall of cylinder acted as a rotary air knife and cleaned the wall areas tended to build up tobacco dust. The results of application showed that after installing the cleaner in cut strips casing cylinder, the average amount of tobacco buildup on the cylinder wall reduced from 40.6 to 3.3 kg/shift. The cleaner has a self-cleaning function, and is simple in structure, it can clean cylinder walls and spikers effectively.
