Description
Technical field
The present invention relates to solid wastes recyclings to utilize technical field, in particular, be related to it is a kind of carried out using mineralized waste it is wooden
The technique of mould plate material integration production.
Background technique
In recent years, as the improvement of people's living standards, housing condition constantly improves, to the quantity and quality of wood materials
Requirement it is also higher and higher.But Global Forests resource is increasingly poor, many place people start to make forest tree resource
With being limited, composite wooden profile material starts the important substitution and supplement as pure wood material, wherein Wood plastic composite
It is exactly a kind of very outstanding composite wooden profile material.Wood plastic composite is one kind using lignocellulosic as primary raw material, warp
Crossing proper treatment is mixed in a certain ratio it with various plastics and adds special auxiliary agent, then through works such as high temperature, extruding, moldings
A kind of novel wooden compound material made of skill has high, corrosion-resistant, Anti-moth-eating the characteristic of intensity.In Wood plastic composite
Raw materials for production research in, majority is using the leftover pieces of new plastics or other plastic products as raw material, and China is annual
Producing has a large amount of waste plastic and lignocellulosic substance not to be utilized effectively in a large amount of house refuse, being capable of becoming property
For valence than higher Wood plastic composite raw material, the raw materials for production using it as Wood plastic composite are a kind of reclamation of solid wastes
The effective way utilized is that Material Field studies a new heat subject in recent years.
To solve the above-mentioned problems, existing Chinese patent application publication No. is that the patent of CN 206264391U discloses one
Kind produces wood plastic building mould production line using house refuse, which includes sequentially connected apron feeder, magnetic separator, rolling

(4) the lightweight class component C that will be screened out in step (2) is delivered to spring screening machine 6 and is sieved again, bounces
Screening machine 6 sieves lightweight class component C by material and sieve plate frictional force and the difference of material own form, after screening
Rubbish be divided into sheet miscellaneous plastic class component G and blocky lignocellulose component two kinds of components of F, miscellaneous plastic class component G is defeated
It send to twin shaft thin broken machine 7, lignocellulose component F is delivered to double-shaft crusher 8.
(5) the spinning fibre class component E come will be screened out in step (3) and the blocky wood fibre come is screened out in step (4)
Class component F, which is delivered to together in double-shaft crusher 8, carries out break process, and mixed component is preferably crushed within 3 mm, after being crushed
Mixed component be delivered to high speed pugging extruder 12.
(6) the sheet miscellaneous plastic class component G that will be screened out in step (4), which is delivered in twin shaft thin broken machine 7, carries out brokenly
Broken processing, broken rubbish partial size are preferably controlled within 5 mm, and broken rubbish is delivered to high speed melting machine 9；At a high speed
The smelting temperature of melting machine 9 is preferably 105~120 DEG C, and material extruded velocity is preferably controlled in 120~180 seconds；In high speed melting
In machine 9, thermoplastic becomes melt liquid state and is extruded in sheet miscellaneous plastic class component G, and it is mixed to be then sent to high speed
Refine extruder 12；Other insoluble plastics are heated in sheet miscellaneous plastic class component G occurs slight carbonization coking formation block carbon
