Embodiment Construction

[0026] The production method of the present invention using waste wood to produce recycled composite boards will be further described in detail in conjunction with the accompanying drawings.

[0027] Such as figure 1 As shown, the production method of utilizing waste wood to manufacture recycled composite boards of the present invention comprises the following process steps:

[0028] a. Sorting waste wood materials into three categories: bulk wood materials, sawdust and shavings, and waste veneers;

[0029] b. Crushing and decomposing large pieces of wood materials;

[0030] c. Needle rolling screening to form four categories of oversized wood chips, qualified wood chips, fine shavings, and wood powder impurities;

[0031] d, oversized wood chips re-enter step b;

[0032] e. Qualified wood chips form medium density fiberboards after dry cleaning of wood chips - metal screening - cooking in a cooking tank - hot grinding - drying - sizing - hot pressing - sanding - sawing. Am...

Abstract

The invention discloses a method for manufacturing regenerated composite boards by using waste wood. The method comprises the following steps of: a, sorting waste wood materials into a massive wood material, sawdust wood shavings and waste veneers; b, crushing and decomposing the massive wood material; c, sorting with a needle roll screen, and obtaining extra large wood chips, qualified wood chips, thin wood shavings and wood meal impurities; d, treating the extra large wood chips according to the step b; e, processing the qualified wood chips into medium density fiber boards by a medium density fiber board manufacturing process; f, removing metal and sand from the thin wood shavings by winnowing, removing powder, gravel and metal impurities from the thin wood shavings by oscillation sorting to form qualified wood shavings, and manufacturing fiber shaving boards by a fiber shaving board production process; g, conveying the wood meal impurities to a fuel bin; h, treating the sawdust wood shavings according to the winnowing process of the step f; i, removing metal and sand from the waste veneers by hammer-type crushing, drying and sorting, and forming crushed materials, big wood shavings and thick wood shavings; and j, producing oriented shaving boards by an oriented shaving board production process.

Description

technical field [0001] The invention belongs to the field of man-made composite board manufacturing, and in particular relates to a production method for using waste wood to manufacture recycled composite boards. Background technique [0002] With the increasing scarcity of forest resources, wood is increasingly becoming a scarce resource. In order to solve the increasingly severe situation, waste wood is currently used in the wood-based panel manufacturing industry, such as medium density fiberboard, particle fiberboard, and oriented strand board manufacturers. The existing methods for manufacturing this kind of recycled composite panels are relatively simple, usually using a single production line, and the production lines cannot be integrated as a whole, and complex types of waste wood cannot be rationally planned and used, resulting in the inability to maximize the recycling of waste wood or reduce the use of recycled composite panels. raw material quality.
