Waste paper recycling system and environmentally friendly printing factory using the same

Abstract

A waste paper recycling system includes a plurality of paper waste collection sub-tanks, a plurality of first pipes, a paper waste collection main tank, a negative pressure device, a second pipe, and a paper brick manufacturing device. The negative pressure device maintains a negative pressure inside the paper waste collection main tank. Through the static pressure difference, the paper edge waste and dust received at the paper waste collection sub-tanks are drawn in through the first pipes and concentrated into the paper waste collection main tank. Then, through the second pipe, they are sent to the paper brick manufacturing device for high-pressure lamination to produce a plurality of paper bricks. This novel system automatically integrates waste collection and resource recovery, effectively preventing dust dispersion and solving the problem of low density in loose waste stockpiles, significantly improving environmental cleanliness, recycling efficiency, and resource reuse value.
