A kind of bending waste plastic scrapes equipment
Technical field
The present invention relates to the technical fields of the reproduction of waste plastic in solid waste resource recycling, are related to waste and old
The equipment of the reproduction of plastics, especially a kind of bending waste plastic scrape equipment.
Background technique
With the fast development of China's industrial economy, up-to-dateness is continuously improved, urban and rural residents' household electrical appliance and industry enterprise
Industry production equipment is scrapped quantity and is sharply increased, and the waste plastics quantity that electric appliance and production equipment generate after scrapping is more and more, makes solid
Waste plastic regeneration in the recycling of body waste material produces the important component for becoming national city mineral products strategy.
Because waste plastic enters reproduction, clean is the premise that industrial regeneration produces, and fraction of residual contamination will be serious
Regenerated plastics raw material quality and utility value after influencing processing.Waste plastic enter reproduction first must thoroughly clean it is dry
Only.
The effective reproduction procedure of processing of waste plastic that remanufacture enterprise carrys out recycling at present: first preliminary broken to use again
Water is cleaned, and is dried after the completion of cleaning, rolls into fragment shape, using sorting, removes waste, finally heated melting,
The waste plastics of melting is squeezed out by plastic extruder, is then carried out traction and is granulated as reclaimed materials.
However the recovery processing mode of this backwardness of poor quality is used for a long time, serious pollution is caused to China's environment and breaks
It is bad.It is much local in the severely afflicated area Zhejiang Province of solid waste recycling, it finds one of maximum pollution sources, is solid plastic rubbish
A large amount of waste water containing heavy metal and greasy dirt that rinsing processing generates are made by more than ten years constant waste plastics recovery rinsing processing
The sewage of industry, these sundries containing heavy metal and bacterium polluted water source and soil in discharge, although carrying out including water at present
Processing etc. various environment protection treating measures, but be all still difficult to avoid that and continue to pollute, hundred kilometers of the circumference in these regions
Interior water cannot be eaten, soil cannot plant, gas cannot exhale, and cause great threat to the life of region resident.
In order to reduce the sprawling of pollution, recent State Ministry of Environmental Protection carries out specific to the cleaning process of recycling waste plastic
The limitation strictly regulated, Chinese Ministry of Environmental Protection's regulation: the stringent environmentally friendly license management system for implementing the processing of waste plastics cleaning reproduction,
Forbid to wash processing privately, otherwise will give criminal sanctions;Waste plastic regeneration produces cleaning must be special in local environmental protection administration
The industrial park that waste plastic regeneration production washing is carried out in the waste plastic regeneration industrial park set up must be provided with reaching pollution
System equipment as defined in water process;Although these environmental regulations of government department make environment pollution control in certain range, but
It is that pollution sources and pollution still have, and be difficult to control as waste plastic generates surging for quantity, at present environmental protection administration
Waste plastics recycling to produce control measure be also makeshift under having no idea.
And for recycling of waste plastics industry, the government department of reinforcement due to to(for) industry environmental protection management intensity,
The reproduction cost that waste plastic regeneration produces enterprise greatly improves;The reclaimed materials of waste plastic is higher and higher using cost,
Seriously threaten the existence of the industry.
Secondly as electric appliance, equipment have used many years just to scrap, therefore the waste plastics outer surface of many recycling is old
Change and differentiation is serious, the outer surface part of these agings and differentiation is not only worth without regeneration, does not remove aging and differentiation
Outer surface also will affect reclaimed materials quality and use value after waste plastic regeneration.
Aging and differentiation layer due to the waste plastics outer surface of recycling, in long-term use adsorption sand and dust, residual
Greasy dirt etc. is stayed to pollute impurity, these pollution majorities are adsorbed on waste plastic in the long-term use process of electric appliance or equipment
Face;Pollutant has been embedded in these agings and differentiation plastic ageing layer and differentiation layer, mixed with the outer surface of these waste plastics
It is integrally formed, it is difficult to wash with water, while cause the existing plastic reclaimed raw material quality being processed by washing reproduction not
Height, utility value are limited.
It is all from plastic containers, greatly that solid waste regeneration, which produces 80% or more the waste plastic that company is recycled, at present
The sheet waste plastics in homogeneous thickness of the bulk dismantled on type household electrical appliance, big part production equipment;Due to these waste plastics
It is classified as PET, PE, PP, PS, ABS etc., the waste plastics economic value that these classify different is different, collects in these waste plastics
Cheng Zhong, precise classification can maximumlly realize the value of waste plastic regeneration raw material;But due to the washing of manufacturing enterprise
Production equipment and technical problem restrict, not before processing by its classification processing, at present to the reproduction of waste plastic progress
Processing method, it is serious unreasonable, cause the serious waste of resource.Existing returned enterprise carries out the waste plastic that recycling comes
Water clean, dry, rolling into fragment shape after, carried out sorting process, reheating is melted, is squeezed out, being granulated into reclaimed materials, but
Be carried out again after rolling into fragment shape sorting accuracy rate it is very low, be not much effect, which cannot achieve maximum value
Utilize above-mentioned waste plastic resource.

The working principle that the present invention is bent " anhydrous to scrape the processing of reproduction raw material " for scraping equipment of waste plastic is:
Categorized waste plastics is sent into the feeding inlet for scraping equipment of present invention bending waste plastic, it will be curved waste and old by baking oven
Plastic sheet softened by baking, then flattened curved waste plastic piece by pressing plain-barreled roll, while by flattening the cutter on plain-barreled roll, will press
Flat waste plastic piece is cut into the neat waste plastic item of rule.
The width of waste plastic item, which depending on the material of waste plastic, will be more difficult to the waste plastic scraped, should more be cut into
Thin some waste plastic items, are cut into thinner waste plastic item and are more conducive to scrape processing;But it cannot be cut into and be narrower than waste and old modeling
Otherwise the thickness of material strip will cause being difficult to control when by the traction plain-barreled roll of traction feed device for waste plastic item, or
It may be cut off when scraping by scraper, or may be by being pulled off when scraping cleaning device;By testing repeatedly, ring is found
Spacing between shape cutting edge 6 is arranged between 0.3 to 2 centimetre relatively more reasonable;The whole waste plastic item of rule is cut by scraping
