Abstract
The utility model discloses a friction electrostatic separation waste plastic granule device, the waste plastic grain flow is through electrification by friction room electrification, a little windy fan increases the granule at the dwell time of electrification by friction room, and the probability of collision of increase granule reduces the speed that the granule got into the electric field, the waste plastic granule of taking the heterogeneity electric charge separates under stable extra electric field, flowed from the export that corresponds respectively by the waste plastic granule of after -separating. Its advantage lies in: the device simple structure, simple to operate, low cost, can isolate the plastics that electrified nature is different high -efficiently, with the electrostatic field to the waste plastic grain sorting, can not cause secondary pollution, the wide range of the waste plastic granule particle diameter that the device can select separately, the anti -blow of little fan reduces the speed that the granule falls, improves between the granule or the granule and the excellent friction and collision that rubs, increases the electrified effect of granule.
Description
Technical field
This utility model relates to the separation of waste or used plastics, particularly to a kind of frictional static sorting waste or used plastics particle device, belongs to separation engineering technical field.
Background technology
In modern society, the usage amount of plastic articles relates to the every aspect of life, constantly soaring due to plastics demand, and plastic articles price is low and the use cycle is short etc., and feature makes the quantity of waste or used plastics be continuously increased.According to statistics, the waste or used plastics that China produces every year is about 5,000,000 tons, and in the trend risen year by year.Owing to the chemical characteristic of plastic material determines that most plastic material can not the most effectively be degraded, and the waste of resource and the pollution of environment can be caused, waste or used plastics is reclaimed, resource necessary to production plastics can not only be reduced, and the improper destruction that environment is caused of plastics recovery can be reduced.
China uses mode for landfill and to burn for the process of waste or used plastics at present.Landfill not only occupies substantial amounts of land resource, and the heavy metal that comprises of plastics and noxious substance once leak and soil, air and water area resource will be caused serious harm；And burn waste or used plastics and not only cause the wasting of resources, also can produce such as the toxic and harmfuls such as two English and hydrogen chloride during burning, after these gas enters air, atmospheric pollution can be caused, even can produce photochemical fog harm environment.
The recycling of waste or used plastics has a great economic significance and social meaning compared with landfill and burning.Present stage, the mode reclaiming waste or used plastics mainly has chemical recovery and machinery to reclaim two kinds.Machinery reclaims compared with chemical recovery, can not only keep the original chemical characteristic of plastics, and machinery recovery cost is low, technique is simple, pollution-free.Machinery reclaims and mainly includes density separation, and optics sorts, froth flotation, frictional static sorting etc..In these sorting modes, frictional static sorting has more efficiently, the feature of low cost, non-secondary pollution, and has sorting particle size range big, it is adaptable to the sorting of waste or used plastics granule.But the equipment of frictional static sorting at present still suffers from some problems: particles collision tribocharge charging effect is poor, and carried charge is low；Equipment fails to realize integration etc..
Summary of the invention
For solving the problems referred to above, this utility model provides a kind of frictional static sorting waste or used plastics particle device, is used for reclaiming waste or used plastics granule, and this device has raising granule and the collision of friction-bar, the advantage increasing the charging effect of granule, can be effectively improved resourcable transformation and the utilization of waste or used plastics.
This utility model be employed technical scheme comprise that to be achieved in that: this utility model one frictional static sorting waste or used plastics particle device is by charging aperture (1), triangle friction-bar (2), upper hangers (3), anelectrode (4), positive electrode plate (5), lower hangers (6), electronegative granule discharging opening (7), mixing waste or used plastics discharging opening (8), positively charged granule discharging opening (9), negative electrode (10), negative electrode plate (11), bolt (13), crossbeam (14), small fan (15) forms.
During device work, starting the small fan on crossbeam, throw in plastic grain subsequently, small fan blows to the wind of triboelectrification room and can reduce granule and enter the speed of electric field, increases the collision probability between granule, thus increases carried charge.In triangle friction-bar areal area, plastic grain is charged by friction with friction-bar, mutually collision between granule is charged, to move downward under gravity from friction-bar areal area after particle charge, engaging friction separation chamber,, owing to connecting with both positive and negative polarity in high voltage power supply, there is stable electric field in the positive electrode plate of Separate With Friction room and negative electrode plate between positive/negative plate.After granule enters into stable electric field, charged particle is under the effect of electric field force, and positively charged granule attracts to negative electrode plate, and electronegative granule attracts to positive electrode plate.
This utility model compared with prior art advantage is as follows:
One, this apparatus structure is simple, easy for installation, with low cost；
Two, electrostatic friction sorting is effective, it is possible to be efficiently separating out the plastics that charged character is different, and the particle size range of separating plastic granule is big；
Three, this device uses electrostatic field to waste or used plastics grain sorting, does not results in secondary pollution；
Four, the back-blowing of fan reduces the speed of particles fall, improves between granule or granule and the frictional impact of friction-bar, increases the charging effect of granule.
