Description
Technical field
The present invention relates to belonging to waste and old composite paper-plastic material processing technology field, more particularly, to a kind of waste and old paper composite wood
Material paper separation production system and separation method.
Background technology
The rapid economic development of China, most of packaging material additional all types of plastic film, color printing press mold all on carton
Form, use composite paper-plastic material, this material is economical and practical, can mildew resistant moistureproof water-impervious, so being widely used in food
Product are packed, and the discarded object producing after being utilized reuses always reluctant burden, milk box packaging paper, film
Paper, pp bag label etc. cover paper and cover moulding material aborning or be necessary for a paper and plastics are completely separable after using, not so cannot be again
Recycle.
The recycling of waste and old composite paper-plastic material is a kind of important channel of resource regeneration, but the difference due to paper
Performance, this kind of material can not directly process recovery: its reason one is that paper bag can be degraded, but plastics can not be degraded；Its reason two
It is that plastics can be with regeneration and granulation, but paper bag is unable to regeneration and granulation.If not processing, both can cause the pollution of environment, and waste
Resource.Reclaimed it is necessary to first carry out separating by paper, then processed respectively.At present, the paper in market separates has using straight
Connect heating, more manually take out the mode tearing apart.The danger that this method presence is burnt, and separate not thorough, make using this side
The properties of product of method salvage material reproduction substantially reduce, high labor intensive, inefficiency.Wet treatment method before this, mainly
It is that the impulsive force relying on water separates with humidity, paper pulp cannot be collected, and floor space is big；Traditional pulper is in order to realize moulding
Material skin and the separation of wood pulp cellulose, mostly using the method fully soaked for a long time, but easily cause waste and the dirt of water resource
Dye, and efficiency is not also high.
The paper piece-rate system of Ye You import developed country is it is well known that developed country refines journey to refuse classification at present
Degree is higher, and the paper piece-rate system of this developed country is to select different piece-rate systems to carry out according to different subdivision rubbish
Process.Domestic refuse classification is also more extensive, and most of city has simply used dualistic formula classification, and can recycle is useless
Old composite paper-plastic material often adulterates other materials, and the paper piece-rate system of developed country causing import is to domestic classification
The process of waste and old composite paper-plastic material has not acclimatized situation: one is the low production efficiency because charging aperture is little；Two is due to useless
In old composite paper-plastic material, other impurity are more, frequently result in its parking；A lot of garbage disposal producers are caused to spend great number foreign exchange to purchase
The import paper piece-rate system high-volume bought is idle.
Chinese Patent Application No.: the patent document of 201020605314.1, publication date: 2012.01.04 discloses a kind of ring
Guarantor's type paper separation system device, by pulverizer, conveyer belt, drum sieve, first washing stock tank, vibratory sieve, conveyance conduit, second
Washing stock tank, vibration slanted screen are linked in sequence composition, and vibration slanted screen is also respectively connected with press master and baling press, using rubbing, soak
Bubble, screening etc. program, so that discarded composite paper-plastic material is effectively peeled off, and will peel off after paper conversion be reduced to paper pulp, will shell
Plastics from rear centralized recovery can directly granulate, and both waste and old paper material was turned waste into wealth, and solved environmental issue again.But should
Utility model washer twice, needs substantial amounts of water to complete, easily causes the waste of water resource, and the pulp washing time
Longer (in order to fully soak), production efficiency has much room for improvement.
