Paper recyclable material humidifying, shredding and extruding treatment method

Abstract

The invention discloses a paper recyclable material humidifying, shredding and extruding treatment method. The method comprises the following steps that a paper recyclable material humidifying machineand a shredding and extruding machine are arranged, wherein the paper recoverable material humidifying machine has a spraying function and a conveying function, and the shredding and extruding machine has shredding, extruding and water filtering functions; paper recoverable materials are conveyed to the humidifying machine, after the spraying system sprays water to the paper recoverable materialfor humidification, the water content is high, paper is soft, stiffness is low, and edge pressing and bonding quality is low; the paper recoverable materials are shredded and then extruded through theshredding and extruding machine, according to the shredded and extruded paper recoverable materials, the paper compression ratio is effectively increased, the paper size is reduced, and the paper specific gravity is increased, so that intensive storage and transfer to a final pulp mill for recycling are convenient; and overflow water of the humidifying machine and filter pressing water of the shredding and extruding machine are recycled. The whole system is compact in equipment, small in working site, capable of being distributed on site, easy and reliable to operate, high in efficiency, freeof scattering and capable of being operated by a single person.

Description

technical field [0001] The invention relates to a treatment method in the recycling process of paper recyclables, in particular to a distributable treatment method for humidifying, shredding, and squeezing paper recyclables. Background technique [0002] In the papermaking process, the amount of water contained in the pulp is a necessary condition for the combination of plant fibers to form paper. Without the mediation of water, the fibers cannot be combined into paper. But moisture can also adversely affect paper properties. The specific performance is that when the moisture in the paper increases to a certain value, serious relaxation will occur even if the very strong fibrous tissue is combined. It can be seen that the strength of fiber bonding decreases with the increase of moisture. In practice, it is shown that the tensile strength of paper reaches the maximum when the moisture content is balanced with a relative humidity of about 30% to 35% (tear and folding resistan...

Problems solved by technology

[0004] With the construction of national waste-free cities, the construction of beautiful countryside and the construction of ecological civilization, urban and rural households are sorting garbage, and the sorted paper recyclables, such as: cartons, cardboard, books, newspapers, paper and other paper products, are currently During the recycling process, folding, compressing, packaging, and transshipment all face the need for a large area of ​​recycling site, small compression ratio, large volume, small specific gravity of paper, heavy dust pollution, high transshipment cost, and high disposal cost; a kind of paper collection is required The recycling method can effectively improve the paper compression ratio, reduce the paper volume, increase the paper specific gravity, no dust pollution, reduce the cost of transshipment, in-situ pulping and concentration, the required recycling site is small, distributed deployment, and solve the problems in the current recycling process
