Description
Technical field
The present invention relates to and belong to waste paper plastic composite materials processing technology field, particularly relate to a kind of waste paper plastic composite materials paper separation of produced system and separation method.
Background technology
The rapid economic development of China, major part packaging material are additional all types of plastic film on carton all, color printing press mold forms, what adopt is composite paper-plastic material, this material is economical and practical, can mildew resistant moistureproof water-impervious, so be widely used in packaging for foodstuff, it is reluctant burden that the discarded object being utilized rear generation utilizes again always, milk box wrapping paper, leaching membrane paper, PP bag label etc. cover paper cover moulding material aborning or use after just paper and plastics must be separated completely, not so cannot be recycled.
The recycling of waste paper plastic composite materials is a kind of important channel of resource regeneration, but due to the different performance of paper, this kind of material directly can not process recovery: its reason one is that paper bag can be degraded, but plastics can not be degraded; Its reason two is that plastics can regeneration and granulation, but paper bag can not regeneration and granulation.If do not process, both can cause the pollution of environment, and waste resource.Reclaim, first paper must be separated, then process respectively.At present, the paper in market is separated to have and adopts directly heating, more manually takes out the mode torn apart.There is the danger of burning in this method, and is separated not thorough, and make to utilize the properties of product of the method salvage material regenerative ratio greatly to reduce, labour intensity is large, inefficiency.Wet treatment method before this, mainly rely on the impulsive force of water to be separated with humidity, paper pulp cannot be collected, and floor space is large; Traditional pulper, in order to realize being separated of plastic skin and wood pulp fibre, mostly adopts long-time way of fully soaking, but easily cause waste and the pollution of water resource, and efficiency is not high yet.
The paper piece-rate system of current Ye You import developed country, as everyone knows, developed country is higher to refuse classification degree of refinement, and the paper piece-rate system of this developed country selects different piece-rate systems to process according to different segmentation rubbish.Domestic refuse classification is also more extensive, major part city only only used dualistic formula classification, can the waste paper plastic composite materials of recycle often to adulterate other material, the process of the paper piece-rate system of the developed country of import to the waste paper plastic composite materials of domestic classification is caused to have not acclimatized situation: one is that production efficiency is low because charging is young; Two is because in waste paper plastic composite materials, other impurity is more, often causes it to stop; The import paper piece-rate system causing a lot of garbage disposal producer to spend great number foreign exchange to buy is left unused in enormous quantities.
Chinese Patent Application No.: 201020605314.1, publication date: 2012.01.04 patent document discloses a kind of environment-friendly type paper separation system device, by pulverizer, conveyer belt, drum sieve, first washing stock tank, vibrating screen, conveyance conduit, second washing stock tank, vibration slanted screen is linked in sequence composition, vibration slanted screen also connects press master and baling press respectively, adopt and rub, soak, screening supervisor, the composite paper-plastic material discarded effectively is peeled off, and be paper pulp by the paper converted back after peeling off, can directly granulation by the plastics of centralized recovery after peeling off, both waste and old paper material was turned waste into wealth, solve environmental issue again.But this utility model twice washer, needs a large amount of water, easily cause the waste of water resource, and the pulp washing time also longer (in order to abundant immersion), and production efficiency has much room for improvement.
