The invention discloses a method for separation of paper and film from paper bags, and relates to the technical field of waste paper recycling. Methods in the prior art for recovering paper materialsfrom waste paper bags are inefficient and costly, and cannot meet the demands for mass production. The method provided by the invention employs following steps are taken: S1, placing mixed soaking liquid in a soaking tank; S2, fixing waste paper bags with paper surfaces facing up and film surfaces facing down on a conveyor belt; S3, rotating a roller to drive the conveyor belt so as to rotate thewaste paper bags into the soaking liquid, and soaking the waste paper bags in the soaking liquid for 20 to 60 seconds; S4, starting the motor, driving the conveyor belt to move by the roller, sequentially bringing the waste paper bags under water spray holes, separating the paper materials by high pressure water under the action of high pressure water spray, and flushing the paper materials into the soaking tank; S5, sucking paper material scraps flushed into the soaking tank by a water pump into a separation tank, conducting separation, and sending separated soaking liquid at the bottom of the separation tank to water spray pipes for recycling; and S6, completing the separation of the paper and the film. The method is simple in operation, easy to implement, and high in efficiency.
Description
technical field [0001] The invention relates to the technical field of waste paper recycling, in particular to a method for separating film from paper from discarded paper bags with film. Background technique [0002] Calcium silicate board is made of loose short fibers such as inorganic mineral fibers or cellulose fibers as reinforcing materials, and siliceous-calcic materials as the main cementing material. Plates made of calcium silicate gel. Calcium silicate board is one of the most advanced cavity wall materials at present, which is waterproof and moisture-proof. Durability, low deformation rate, heat insulation, etc., are especially suitable for use as wall panels and ceiling panels inside buildings. [0003] Calcium silicate board is a kind of siliceous material (main component is SiO2, such as quartz powder, granite, diatomaceous earth, etc.), calcium material (main component is CaO, such as lime, carbide mud, cement, etc.), reinforced Fiber materials, additives, ...
