Problems solved by technology

The wet pulp circulates in the machine, and is cut horizontally by the action between the flying knife and the bottom knife, longitudinally separated, crushed, swelled, etc., so as to make a pulp that meets the requirements of papermaking. The sheet area of ​​the latex fiberboard is large, which makes it difficult for the material to enter between the fly knife roller and the bed knife roller, and circulate in the beater, resulting in a very low pre-treatment efficiency after feeding.

Embodiment Construction

[0023] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0024] Such as figure 1 Shown, the recycling method of latex fiberboard comprises the steps:

[0025] a), the latex fiberboard is put into the crusher and crushed until the size of the board in the obtained broken board is less than or equal to 50mm*50mm;

[0026] b), put the crushed sheet material and wetting agent into the high-concentration hydraulic pulper, and the addition amount of the wetting agent is 1%-5% of the mass of the crushed sheet material added to the hydraulic pulper, so that the hydraulic crushing The pulper performs pulping treatment in an environment where the concentration of the slurry is 5%-15%, until the size of the plates in the crushed pulp is less than or equal to 2mm*2mm;

[0027] c), put the crushed slurry into the beating tank, and adjust the concentration of the slu...

Abstract

The invention relates to the production field of latex fiberboards, in particular to a latex fiberboard recycling and reusing method and a recycling and disposal system applying the same. The latex fiberboard recycling and reusing method comprises the following steps that (a) the latex fiberboards are put into a crushing machine, and crushing treatment is performed to obtain a crushed board material; (b) the crushed board material is put into a hydropulper, and pulping treatment is performed to obtain a pulp material; (c) the pulp material is put into a beating pond, and a beating machine is adopted to perform beating treatment so as to obtain a primary pulp material; (d) the primary pulp material is subjected to filtration treatment to obtain a refined pulp material for storage and stand by application; (e) the refined pulp material in a pulp storage pond is taken out and delivered to a pulp preparing system. The recycling and disposal system can efficiently recover and reuse a large area of latex fiberboards in a low-energy-consumption mode, on the one hand, the production cost is saved, and on the other hand, waste and environmental pollution are also avoided.

Description

technical field [0001] The invention relates to the production field of latex fiberboards, in particular to a recovery and reuse method for latex fiberboards and a recovery treatment system using the same. Background technique [0002] Latex fiberboard refers to the inner sole material that contains natural plant fibers, synthetic fibers and polymer materials, and is used in the shoe industry after special processing technology. It has the characteristics of flexibility, elasticity, air permeability, wear resistance, and durability. It can meet the requirements of foot comfort, sanitation, modern hot-melt bonding and other shoe-making technologies. As a special fiberboard material, latex fiberboard is a shoemaking material developed to replace leather, borrowing non-woven fabric and recycled leather technology, and improving its performance. [0003] Latex fiberboard is used in the shoemaking industry, which requires certain structural properties, processing properties and ...
