Abstract

The invention discloses a PET (polyethylene terephthalate) air flotation separation device which is characterized by comprising main equipment such as a pressure pump, a dissolved air tank, an air compressor and an air flotation cleaning tank. Air in the dissolved air tank is pressurized and dissolved into water to reach a saturation state so as to form dissolved air water; after the air flotation cleaning tank is filled with the dissolved air water, microbubbles released from the dissolved air water can be attached to the surface of a separation material to change the buoyancy force of the separation material so as to achieve the purpose of separation. Impurities with different specific gravities in PET raw materials can be effectively separated by adjusting the proportion of the dissolved air water in filled cleaning water. The PET air flotation separation device is of a cleaning tank structure, can be conveniently embedded into a PET recovery production line, and is capable of automatically separating out the impurities from the PET raw materials to achieve the purpose of quality control and effectively improve the market competition advantage of enterprises.

Description

A kind of PET air supporting sorting unit
Technical field
The present invention relates to a kind of sorting unit, particularly sorting label paper in PET raw material.
Background technology
PETG (PET) is a kind of synthetic material that just obtains general development from latter half in the sixties, and the product variety of PET is expanded to several thousand kinds of specifications of hundreds of product of multiple series such as polyester staple fiber, polyester filament, polyester bottles, polyester film, non-weaving cloth, engineering plastics and composite multifunction product by initial polyester staple fiber.Due to the continuous increase of social demand, PET production of polyester rapid growth.China PET production capacity has exceeded 2,000 ten thousand tons in 2008, become world PET and produce, consume the first big country.
PET product is mostly one-time consumption product, and the thing followed is a large amount of waste PET materials.Waste PET materials chemistry inertia is strong, in the short time, is difficult for by air or microbial degradation, occupies large quantity space, causes " white pollution ".Current task of preserving the ecological environment is very urgent, and waste PET material is reclaimed, and for environmental protection, economizes on resources, and sustainable development is of great advantage.The regeneration of waste PET beverage bottle, not only can reduce environmental pollution, and can turn waste into wealth, and therefrom obtains huge economic interests.Along with non-fine the universal of PET and other packing articles of using, PET reclaims and the technology of reprocessing occurs in a large number.At present the continuing, increase rapidly of PET package consumer amount, in the urgent need to increasing recovery and the utilization of PET discarded object, PET material recovery technology is also constantly brought forth new ideas again.
PET reclaims in raw material, and having a kind of is the raw material of fragment form, and this raw material is produced through techniques such as whole bottle pulverizing, simple rinsings.Due to the inconsistency of standard, the PET fragment raw material of factory's buying usually mixes the plastic flakes that has non-PET.Conventional P ET recovery processing technique is often with manual mode sorting, and hand-sorting efficiency is low, cost is high, and is difficult to control product quality, thereby causes the disappearance of enterprise competitiveness.
Summary of the invention
The present invention completes in view of the above problems, and its object is to provide a kind of PET air supporting sorting unit, can embed PET remanufacture line, and automatic sorting separates the plastic flakes of non-PET, makes the product quality of original PET recovery processing production line, is able to effective lifting.
PET air supporting sorting unit of the present invention, is characterized in that:
Comprise the capital equipments such as force (forcing) pump, dissolving, air compressor, air supporting rinse bath.
Described dissolving dissolves in by air pressurized the formation dissolved air water that reaches capacity in water, injects after air supporting rinse bath, and the microbubble that dissolved air water disengages will be attached to sorting thing surface, to change the buoyancy of sorting thing, reaches the object that sorting separates.
Described PET air supporting sorting unit is rinse bath structure, in rinse bath internal groove bottom both sides, respectively has a dissolved air water ascending pipe, and hole is penetrated by fixed intervals processing dissolved air water in the top of described dissolved air water ascending pipe, wherein penetrates the aperture in hole and can adjust.
On described bottom of rinse bath propeller blade face, make the blade with tipping effect, when rinse bath air supporting cleaning, in groove, air supporting cleaning materials is ceaselessly stirred, and makes it contact fully dissolved air water.
Described PET air supporting sorting unit, accounts for the ratio of cleaning injected water volume by adjusting dissolved air water, and effectively sorting separates the impurity of different specific weight in PET raw material.
According to the present invention, described PET air supporting sorting unit embeds after PET remanufacture line, and effectively sorting separates the non-PET plastic flakes in PET fragment raw material, to reach the object of controlling quality, and the effectively market competition advantage of enterprise.

The specific embodiment
Below, with reference to accompanying drawing, the PET air supporting sorting unit of embodiments of the present invention is elaborated.
Fig. 1 is the schematic diagram of the PET air supporting sorting unit of embodiments of the present invention.As shown in Figure 1, comprise the capital equipments such as force (forcing) pump 1, dissolving 2, air compressor 3, air supporting rinse bath 4.
Respectively there is a dissolved air water ascending pipe 5 described air supporting rinse bath 4 internal groove bottom both sides, described dissolved air water ascending pipe 5 tops, and by the ejaculation hole of fixed intervals processing dissolved air water, its aperture of penetrating hole can be adjusted.
On described air supporting rinse bath 4 bottom propeller 6 blade faces, make and have tipping effect blade 7, when air supporting rinse bath is worked, in groove, air supporting cleaning materials is ceaselessly stirred, and makes it contact fully dissolved air water.
By adjusting dissolved air water, account for the ratio of cleaning injected water volume, can effectively control the impurity of floating different specific weight, impurity is cleaned water and takes rinse bath out of from overfall 8, the object separating to reach sorting.
PET air supporting sorting unit of the present invention embeds after PET remanufacture line, and effectively sorting separates the plastic flakes of non-PET in PET fragment raw material, to reach the object of controlling quality, and the effectively market competition advantage of enterprise.
