The traditional method for recycling waste and recycled paper products (hereinafter collectively referred to as waste paper) is to wash a large amount of waste and recycled paper products by water power, precipitate after washing, float carbon powder products and printing ink attached to the waste and recycled paper products on the upper layer of water due to lighter density relative to water, settle washed fibers on the lower layer of water due to swelling and heavier density relative to water, and therefore, the waste paper subjected to water treatment is usually deinked by a method (namely flotation) of skimming the carbon powder products and the printing ink suspended on the upper layer of water; the method for recycling waste paper has the advantages that the principle of operating equipment is simple, the quality result of the processed fiber is stable, but the defect is obvious, a large amount of fresh water or even clear water resources are needed in the processing process, the environment and the field for using the equipment are also under hard conditions, the traditional waste paper utilization is cost reduction, and under the condition of no supervision, the waste water and waste materials generated in the production process are directly discharged into rivers and air, and the waste water and waste materials cannot be recycled through refining treatment. At present, there are some researches on the manner and equipment for recycling waste paper by dry treatment, which can be basically classified into laser treatment method, and conventional air separation method, such as: JP11-133822A discloses a device for recovering waste paper and removing ink, the evaporated ink is sucked by a suction device, the effect is only useful for waste paper printed by laser, the device has the advantages that the mark printed on the paper and paper can be removed without decomposing the paper or product, the laser separation method generates selective photo-pyrolysis effect based on the ink on the paper which is clearly and evaporated by laser irradiation, so that the ink molecules printed on the paper are actively exploded and loosened, but the effect is limited, the device only acts on the laser printing products, and the effect is ineffective or not obvious for the ink and the writing waste paper. In JP1975069306, the air separation method mainly breaks waste paper into fibers in an anhydrous state, breaks pigments printed on the paper in the state, separates the pigments from the fibers by utilizing the difference between the weight of the pigments in the broken state and the weight of the fibers in the broken state, is mainly used for waste paper printed by carbon powder laser, cannot physically remove UV ink with relatively high pigment density, is not easily separated in the air due to the similarity of the weight of the heavy pigments and the weight of the fibers after the breaking, is easy to entangle with the broken fibers and affects the quality of the treated paper fibers, and therefore, paper products produced by the fibers in the method need to be further bleached or covered in color. In patents CN101736635 and EP659932A, various magnetic devices are used to stir, add magnetic seeds into the pulp, filter and other ways to directly contact the water-soluble fiber pulp, and the magnetic force is applied to adsorb the ink in the pulp through various structures, but in the actual production process, the magnetic field of the way cannot be quantitatively estimated, the excessive magnetic field affects the operation and use of the whole paper-making and pulping device, the insufficient magnetic field can make the ink not be effectively removed, and the subsequent procedures of fiber bleaching and washing are increased.

Secondly, the disintegrated fiber ink material, no matter carbon powder ink material or ink and ink and other ink materials can slightly disturb ink particles through a magnetic field of the magnetic force coupling vibrator to act on mineral components in the ink material, so that the ink material and the fiber are stripped or are broken due to coupling vibration, and a spectral band is divided into two bands to be subjected to simple wave vibration. Different from the traditional water slurry magnetic adsorption, an unquantifiable strong magnetic field is needed, so that the operation system and the operation of adjacent equipment are influenced.

Thirdly, the ink particles generate calculable motion tracks through the magnetic force difference coupling vibrator, and equipment capable of capturing the tracks is designed to collect the ink.
