ABSTRACT:
Disclosed is an apparatus for recycling scrapped POLYLON which mainly includes a scrap crashing and feeding unit, a scrap melting unit and a waste gas treatment unit. The scrap crashing and feeding unit includes a top, a left, and a right rollers with toothed cutter to break the scraps into smaller pieces which are pushed onto a feeding roller located below the above three rollers and having spiral grooves to automatically carry and feed the small scrap pieces into the melting unit. The scrap melting unit has a plurality of rod-shaped electric heaters wrapped with thermo-conductive material and squarely arranged in a furnace around the feeding roller to evenly heat the furnace and quickly melt the scrapped POLYLON pieces. The waste gas treatment unit filters waste gas produced by the melting unit and is sequentially divided into an inner filter segment containing industrial wool and active carbon, a cooling segment with condenser pipes, a spraying segment providing water spray to cool the waste gas, an industrial wool segment, and an active carbon segment, so that the waste gas is deodored and purified to become refresh and clean air again before it is discharged to the open air.
