Printed paper product recycling method

Abstract

The invention relates to a printed paper product recycling method, which uses pulping equipment. The pulping equipment comprises a shell, a feeding pipe, a discharging pipe, a water inlet pipe, a crushing device and a pulping device. The specific method for recycling printed paper products by adopting the pulping equipment comprises the steps of classifying and recycling, crushing and pulping, deinking and bleaching, compression molding and paperboard cutting. The crushing device comprises a driving motor, a driving gear, a driven gear ring, a connecting pipe, a driving rotating shaft, a spraying mechanism, a crushing cutter, a first sieve plate, a transmission mechanism, a baffle ring, a supporting plate, a partition plate and a water spraying pipe. Through the cooperation of the crushingdevice and the pulping device, the function of making waste paper printed matter into paper pulp is achieved, paper products can be wetted in advance before crushing so as to reduce the crushing difficulty, the homogenizing mechanism can continuously stir the pulp in the pulping process, and the paper pulp at all positions can make full contact with crushing blades.

Description

technical field [0001] The invention relates to the field of recycling and processing of printed products, in particular to a method for recycling and reusing printed paper products. Background technique [0002] With the development of society and the improvement of living standards, people come into contact with more and more printed paper products in their daily lives. Printed paper products need to consume a lot of wood during production. If the waste printed paper products are not recycled and reused, It is bound to increase energy consumption and increase the burden on the environment. [0003] At present, more and more people are aware of the necessity of recycling printed paper products. One of the main steps in the recycling of paper products is pulping, but there are still the following problems in the process of pulping printed paper products: [0004] (1) In order to shorten the pulping time, paper printed matter is usually crushed before pulping. The crushing t...

Problems solved by technology

[0004] (1) In order to shorten the pulping time, paper printed matter is usually crushed before pulping. The crushing tool needs to continuously crush paper products. The tool wears a lot and has a short service life, which increases the maintenance cost of the manufacturer. ;

[0005] (2) Due to the limited rotation range of the pulping rotor, the pulp that is far away from the rotor cannot be fully sheared, so it is easy to have uneven specifications of the pulp produced in the same batch. In order to process the pulp that does not meet the specifications Need to increase follow-up processing procedures, delaying the overall work progress
