CN104785455A - Reclaimed waste plastic high-accuracy intelligent color sorting method - Google Patents

Abstract

The invention relates to a reclaimed waste plastic high-accuracy intelligent color sorting method which is characterized by comprising the following steps that 1, sheet or particle plastic products which are ground and subjected to iron removal are conveyed into a color sieving machine and the sheet or particle plastic products finally pass through a main sieving passage one by one through a sequencing passage in a color sorter; 2, a row of color sieving sensors are arranged on the main sieving passage and the sheet or particle plastic products selected by the color sieving sensors can fall into a collecting cabin from a bottom inlet which is rapidly opened; 3, the unselected sheet or particle plastic products can pass through the main sieving passage, the bottom inlet cannot be opened and then the unselected sheet or particle plastic products enter the next sensor to be subjected to color sieving, so that the sheet plastic products with different colors can fall into different collecting cabins by different color sieving sensors, and therefore, color sieving and recollection are completed. A high technical means is adopted to replace a manual sorting manner and a producing labor force is reduced; compared with the manual sorting manner, the high technical means adopted by the reclaimed waste plastic high-accuracy intelligent color sorting method has a higher speed, is more sustainable and greatly improves production efficiency.

Description

Regenerating waste used plastics high-precision intelligent color sorting process

Technical field

The present invention relates to regenerated plastics look selecting technology field, be specifically related to a kind of regenerating waste used plastics high-precision intelligent color sorting process.

Background technology

Along with industrial expansion, the application of plastic products is throughout the every field of industrial or agricultural and daily life, the waste or used plastics rubbish of whole world generation every day cannot be estimated, but its large pressure of tool caused environment is apparent, in order to process these plastic garbages, existing method is generally landfill, burning etc.But because the natural degradation of common plastic garbage is chronic, generally will could degrade through century-old, and also can produce the harmful substances such as a large amount of methane in degradation process, therefore landfill method has obtained denouncing of a lot of expert; And pernicious gas, flue dust etc. that burning method produces directly impact environment.Simultaneously because plastics are as petroleum chemicals, its primary raw material produced is oil, and it is a kind of non-renewable resources, and current Global Oil contention is more and more fierce, crude oil cost is more and more higher, and therefore recycling for plastic product is the best approach solving plastic garbage problem at present.It effectively solves the threat of plastic product to environment, also can promote resource regeneration simultaneously.

At present, the Portable drinks such as bottled mineral water due to its be convenient for carrying, the feature more and more welcomed by the people such as clean hygiene, be thereupon produce a large amount of waste plastic bottles.For recycling these waste plastic bottles, need to carry out fragmentation, cleaning, removing impurities etc. to it, traditional recovery process and reclaimer technology content not high, cost recovery is large, and the cost performance attached by recovery is unsatisfactory.Because discarded plastic bottle exists shades of colour, after its pulverizing, shades of colour mixes and cannot distinguish, and to utilize these raw materials to carry out processing in traditional handicraft be all compound with multiple color, the easy like this end product quality that causes is not high, and color is inconsistent.

Summary of the invention

Technical problem to be solved by this invention is to provide one to be applicable to sheet, granular regenerating waste used plastics high-precision intelligent color sorting process.

Technical problem to be solved by this invention realizes by the following technical solutions:

A kind of regenerating waste used plastics high-precision intelligent color sorting process, it is characterized in that, described method step is as follows:

1) sheet after deironing will be pulverized or particular plastics goods send into sieve look machine through conveyer belt, via returning sequence passage finally piecemeal by main screening passage in color selector;

2) main screening passage is provided with a row sieve colour induction device, and the sheet chosen by sieve colour induction device or particular plastics can fall into from the bottom inlet automatically opened rapidly and collect cabin;

3) do not have selected will passing through, bottom inlet can not be opened, and then enters next inductor and carry out sieve look, and the slice plastic of such different colours will be fallen into by different sieve colour induction devices and different collect cabin, thus completes dithering and collect.

The invention has the beneficial effects as follows:

1) adopt high-tech means to replace manual sorting, reduce input of labor;

2) compare manual sorting, speed is faster, and sustainability more, substantially increases production efficiency;

3) can be used for the sieve look diversity of various sheet, particular plastics, can apply in the middle of waste plastic regeneration production line.

Detailed description of the invention

The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with specific embodiment, setting forth the present invention further.

A kind of regenerating waste used plastics high-precision intelligent color sorting process, described method step is as follows:

1) sheet after deironing will be pulverized or particular plastics goods send into sieve look machine through conveyer belt, via returning sequence passage finally piecemeal by main screening passage in color selector;

2) main screening passage is provided with a row sieve colour induction device, and the sheet chosen by sieve colour induction device or particular plastics can fall into from the bottom inlet automatically opened rapidly and collect cabin;

3) do not have selected will passing through, bottom inlet can not be opened, and then enters next inductor and carry out sieve look, and the slice plastic of such different colours will be fallen into by different sieve colour induction devices and different collect cabin, thus completes dithering and collect.

The present invention adopts high-resolution image sensor, is equipped with High-Speed Automatic recognition technology analysis process system, and imageing sensor can convey to control treatment system by the identifying information of plastics, and then provides instruction and whether pass through.

More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
