Description
Technical field
The present invention relates to waste and old paper products to recycle correlative technology field, and in particular to a kind of dry separation of waste and old paper composite wallpaper
Method.
Background technique
It is compound and form to be generally the paper such as the plastic cement such as PE, PP and brown paper, cardboard for paper-plastic stick wallpaper currently on the market
Novel wallpaper.And usual paper-plastic stick uses resin application methods, such as hand brush in the production of paper-plastic stick wallpaper, machine applies, spraying etc.
Mode reaches plastic box paper and closely combines for a long time.
Wallpaper finishing, the later period will generate a large amount of waste and old paper-plastic stick wallpapers, and waste and old wallpaper is largely eliminated and causes to provide
Source amount is taken and environmental pollution, therefore is necessary to the recycling of waste and old paper composite wallpaper.
In traditional handicraft, paper separation is to utilize the method for changing plastic realization paper separation after heating.(1) heat point
Method utilizes the method for changing plastic realization paper separation after heating；(2) hygroscopic water method will obtain light from dry point-score separation equipment
Material is sent into pulper, and the paper pulp blended is flowed out from the aperture on sorting plate, and the plastics left are then from a separation outlet
Discharge is then fed into dewaterer dehydration, is re-fed into air separator and is separated；(3) electronic partition method is by paper and plastics
Mixture is sent into seperator by oscillating feeder, and fall into rotation pulverizes drum, be then delivered to by wire electrodes with pulverize
Between the corona zone that is formed, paper is attracted to electrode, and plastics are still attached on rotary drum, as bulging rotation plasticity falls on its bottom
Portion collects.Had a significant impact using humidity when this method to separating resulting, when mixture humidity is 15%, though paper and modeling can be made
Material separation, but plasticity can still be polluted by a large amount of paper, when humidity is improved to 50% or more, plasticity and paper can be made to be kept completely separate.
In the art, CN201610538265.6 discloses a kind of waste and old composite paper-plastic material paper separation life
The separation method of production system staticly settles → paper pulp extruding → modeling by paper separation → paper pulp removal of impurities → paper pulp in this application
Piece compression packing and etc., it realizes waste and old composite paper-plastic material paper separation and improves production efficiency, suitable for country's classification
The purpose that any waste and old composite paper-plastic material and water resource recycle.
Chinese Patent Application No.: 201020605314.1, publication date: the patent document of 2012.01.04 discloses a kind of ring
Guarantor's type paper separation system device, by pulverizer, conveyer belt, drum sieve, the first washing stock tank, vibrating screen, conveyance conduit, second
Composition is linked in sequence in washing stock tank, vibration slanted screen, and vibration slanted screen is also respectively connected with press master and baling press, using rubbing, leaching
The programs such as bubble, screening, are effectively peeled off discarded composite paper-plastic material, and the paper conversion after removing is reduced to paper pulp, will shell
Plastics from rear centralized recovery can be directly granulated, and not only waste and old paper material be turned waste into wealth, but also solve environmental issue.But it should
Utility model washer twice, needs a large amount of water to complete, and be easy to cause the waste of water resource, in order to sufficiently impregnate,
The pulp washing time is also longer.A large amount of water are used in the separation process of paper-plastic stick wallpaper in the art, cause water resource unrestrained
Take but caused by Heisui River, waste water, sewage discharge, caused by a large amount of water pollutions to environmental hazard.
Summary of the invention
Technical problem to be solved by the present invention lies in provide a kind of dry isolated method of waste and old paper composite wallpaper.Including
Sorting is broken to be separated two modules with paper and can realize and be completely separated to two kinds of materials of paper-plastic stick wallpaper, and separation process is
It is first sorted, is crushed by shade, level-one separation, the second-order separation, three-level separation is completely separated and high efficiente callback,
Whole process is not paddled completely, has overturned traditional handicraft and commercial run, avoids water resource waste and waste water, sewage discharge
Caused by a large amount of water pollutions to environmental hazard.
The following technical solution is employed for the technical problems to be solved by the invention to realize:
A kind of dry isolated method of waste and old paper composite wallpaper, includes the following steps:
(1) it sorts: the waste and old paper composite wallpaper elder generation artificial screening of recycling being shrugged off into a large amount of dusts, removes clod, iron block
Equal junks；Waste and old paper composite wallpaper is divided into 2 major class simultaneously: dark colour wallpaper and light colour wallpaper will classify waste and old
Paper-plastic stick wallpaper is orderly placed in ventilation, drying, clean place；
Shade is identified: passing through publicity: g=R*0.299+G*0.587+B*0.114,
It is light color as g >=192；
It is dark color as g < 192；
(2) it is crushed: sorted waste and old paper composite wallpaper being put into respectively and carries out slice shearing-crushing in crusher, break
Broken wallpaper range 3-10cm × 3-10cm；
(3) it separates:
(a) the blocky paper-plastic stick wallpaper after shearing-crushing is entered by pipeline and grinds separation equipment one fraction of progress
From, moulding composite wallpaper by the gear grinding shredded paper in equipment in level-one separation becomes clastic, in attrition process plastics and
The available separation of papery, obtained clast part be PVC or PE plastics, be partially paper product, partially for PVC or PE not with paper
The separated paper-plastic stick clast of matter, while starting air blast in level-one separation, it is separated using the difference of paper specific gravity by wind-force
Paper clast through grinding, wherein PE or PVC enters magnetic separation separation equipment by grinding the plastics separate pipeline of separation equipment, wood
Matter fiber enters dry closing paper scrap workshop, PVC or the non-paper-plastic stick clast of PE by another separate pipeline by grinding
The plastics separate pipeline of separation equipment enters magnetic separation separation equipment；
(b) after paper clast completes level-one separation, the second-order separation is carried out in magnetic separation separation equipment, the second-order separation passes through magnetic
Choosing separation paper separates, after magnetic separation separation by wood fibre and PVC by propeller break up with progradation constantly forward, at
Function enters separator, separates three-level separation i.e. thorough point for reaching paper with magnetic separation by the specific gravity screening of wind-force in the separator
From plastic scrap enters plastic conduit collector, and paper clast enters shredded paper collector.

Another separate pipeline enters dry closing paper scrap workshop, and the paper-plastic stick clast that PVC or PE are not separated with papery passes through mill
The plastics separate pipeline of broken separation equipment enters magnetic separation separation equipment；
(b) after paper clast completes level-one separation, the second-order separation is carried out in magnetic separation separation equipment, the second-order separation passes through magnetic separation point
Separated from paper, after magnetic separation separation by wood fibre and PVC or PE by propeller break up with progradation constantly forward, at
Function enters separator, separates three-level separation i.e. thorough point for reaching paper with magnetic separation by the specific gravity screening of wind-force in the separator
From plastic scrap enters plastic conduit collector, and paper clast enters shredded paper collector.
