Problems solved by technology

The waste books used by middle school students in schools are an important resource for paper regeneration. At present, the waste books recycling pulping equipment mainly includes: paper shredders, deinking machines, pulping machines and thickeners. Each device has its own power. In addition, additional power is needed to transport the slurry between the devices, which causes the disadvantage of high energy consumption in the entire pulp industry and increases production costs; and the waste books used by students are usually bound. It often contains a large amount of fastening substances such as glue and iron nails. Glue and iron nails are difficult to remove in the process of deinking, pulping, and concentration. It often takes a lot of time and cost to remove the glue in the slurry. It greatly increases the processing cost of waste books, and also reduces the pulping efficiency and pulping quality of waste books. At the same time, a large amount of industrial waste liquid is generated, which increases the subsequent processing cost

Embodiment 1

[0034] Such as figure 1 As shown, the present invention provides a process for treating waste and used books, including the following steps arranged in sequence from high to low: (1) edge trimming, the edges of waste and used books with glue or iron nails are cut off by an edge trimmer 1; 2) crushing, the waste books with glue or iron nail edges will be removed through the hydropulper 2, and the ink marks will be discharged through the deinking overflow pipe 6 during the crushing process; (3) pulping, the crushed materials will be Paper pulp is made in the pulping machine 3, and the ink is deinked while stirring during the pulping process, and the ink stains that come out are discharged through the ink discharge pipe 7; (4) concentrate, use the thickener 4 to concentrate; (5) store the pulp, concentrate the The slurry is stored in the slurry storage tank 5. Wherein, the water filtered out after concentration in step (4) is returned to step (2) and step (3) for recycling throu...

Embodiment 2

[0038] Such as figure 1 As shown, the present invention provides a waste book processing equipment, including an edge trimmer 1 for cutting off the edges of waste books with glue or nails, and a machine 1 for cutting off the edges of waste books with glue or nails. The positions of the hydraulic pulper 2, the pulper 3, the thickener 4, and the stock tank 5 for crushing waste books, the trimmer 1, the hydropulper 2, the pulper 3, the thickener 4, and the stock tank 5 Arranged in order from high to low, water delivery pipes 8 are provided between the concentrator 4 and the hydraulic pulper 2 and pulper 3 . The edge trimmer 1, the hydropulper 2, the pulper 3, the thickener 4 and the pulp storage tank 5 are all commonly used equipment in the prior art, and those skilled in the art can directly refer to the existing equipment on the market for implementation.

[0039] Of course, in order to make this waste book processing equipment more perfect and use better, the inventor has mad...

Abstract

The invention discloses a treatment process and equipment of waste books and belongs to the technical field of waste paper recycling. The treatment process sequentially includes the steps, from top to bottom, of firstly, using an edge-cutting machine to cut off the edges, with glue or iron nails, of the waste books; secondly, using a hydrapulper to crush the waste books obtained after the first step, and using a ink-removing overflow pipe to discharge ink during the crushing; thirdly, using a pulping machine to make the crushed materials into pulp, performing ink removing while stirring during pulping, and discharging the removed ink through an ink discharge pipe; fourthly, using a concentrator to perform concentration; fifthly, storing the concentrated pulp in a pulp storage tank. The treatment process and equipment has the advantages that the process and equipment is simplified, energy consumption is lowered, the discharge of industrial waste liquid is reduced, the pulping efficiency and quality of the waste books are increased, and the process and equipment is widely applicable to waste paper treatment.

Description

technical field [0001] The invention relates to the technical field of waste paper recycling and reuse, in particular to a waste book treatment process and equipment. Background technique [0002] With the continuous consumption of global forest resources, the wood pulp produced from trees is becoming more and more scarce, and the recycling and reuse of waste paper has become a common practice in the world. The waste books used by middle school students in schools are an important resource for paper regeneration. At present, the waste books recycling pulping equipment mainly includes: paper shredders, deinking machines, pulping machines and thickeners. Each device has its own power. In addition, additional power is needed to transport the slurry between the devices, which causes the disadvantage of high energy consumption in the entire pulp industry and increases production costs; and the waste books used by students are usually bound. It often contains a large amount of fa...
