Problems solved by technology

Patents CN101736635 and EP659932A disclose using various magnetic devices to directly contact water-soluble fiber pulp by stirring, adding magnetic seeds to the slurry, filtering, etc., and applying magnetic force to absorb the ink in the slurry through various structures, but in actual production The magnetic field of this method cannot be quantified and estimated during the process. Excessive magnetic field affects the operation and use of the overall papermaking and pulping equipment. Insufficient magnetic field will make the ink unable to be effectively removed, which will increase the subsequent fiber bleaching and washing process.

Abstract

The invention discloses a method and device for separating printing ink from fibers by dry-process magnetic force difference coupled vibration. The device comprises a fiber crushing machine unit (1),a magnetic force difference coupled vibrator (2), an acceleration fan (3), a ballistic rebounding and resorbing device (4), a material settling and conveying pipe (5) and a cylindrical separator (6) which are sequentially connected through a pipeline. According to the method and the device, separation of printing ink and fibers in the waste paper can be achieved through dry-process magnetic forcedifference coupled vibration, and recycling of waste paper products is achieved.

Description

technical field [0001] The invention relates to the field of waste paper recycling equipment and methods, in particular to a method and equipment for dry magnetic force difference coupling vibration separation of ink and fibers. Background technique [0002] Paper is an important product closely related to people's production and life. It is combined with the natural environment. Waste paper is an important renewable resource. Its reasonable recycling not only has good economic and social benefits, but also has great impact on environmental protection and resource utilization. is of great significance. The traditional method of recycling waste and recycled paper products (hereinafter collectively referred to as waste paper) is to wash with a large amount of water power, and then precipitate after washing. Floating on the upper layer of the water, the washed fibers settle in the lower layer due to swelling and their own density relative to the water. Therefore, the water-tre...
