Technical field

The utility model relates to a kind of waste plastic multipass sort system, belongs to waste reclaiming device technical field.

Background technology

Nowadays, along with the acceleration of urban development paces, the discarded object that daily life produces gets more and more, if effective these discarded objects of recycling become the task of top priority of environmental improvement, in these discarded objects, the white pollution especially based on plastic garbage is the most serious, these plastics are generally make with macromolecular compounds such as polystyrene, polypropylene, polyvinyl chloride, due to Stability Analysis of Structures, be difficult to degraded so that severe environmental pollution.Existing recoverying and utilizing method mostly adopts catalystic pyrolysis, will make industrial chemicals and fuel, and the method can not cause secondary pollution, but higher to technical requirement, particularly reclaims assorting room and catalytic process, directly can affect the quality of final products.

Existing recovery assorting room mostly adopts pneumatic separating technology, this technology is different by the density of plastic products and impurity, volume, when freely falling under wind condition, the resistance be subject to is different, thus moving the change of track, the sorting realizing raw material according to the drop point distance of light plastic is reclaimed.But, the method is owing to directly adopting pneumatic separating, the windage produced in systems in which is larger, thus energy consumption is larger, do not meet resource-effective principle, and be often mingled with a lot of impurity in the plastics after sorting, the product quality obtained after causing catalytic pyrolysis is lower, if thus improve the much-talked-about topic that the efficiency reclaiming sorting becomes research downwards.

Detailed description of the invention

The utility model provides a kind of waste plastic multipass sort system, comprise material conveyer belt 10, accelerate conveyer belt 20, triangle conveyer belt 30 and collecting bin, material conveyer belt 10, accelerate conveyer belt 20, the conveying direction of triangle conveyer belt 30 is identical, the feed end correspondence of described acceleration conveyer belt 20 is arranged on the below of material conveyer belt 10 discharge end, the feed end of described triangle conveyer belt 30 is lower than the discharge end accelerating conveyer belt 20, the gait of march of described material conveyer belt 10 is less than the gait of march accelerating conveyer belt 20, described collecting bin at least comprises two, the discharge end of the corresponding triangle conveyer belt 30 of the first collecting bin 40, second collecting bin 41 correspondence accelerates the discharge end of conveyer belt 20, scraper plate 61 is provided with below described acceleration conveyer belt 20 discharge end, gap is maintained between described scraper plate 61 and acceleration conveyer belt 20, described scraper plate 61 lower end is fixedly connected with deep bead 60, described second collecting bin 41 is inverted cone-shaped structure, be filter plate 70 bottom second collecting bin 41, be air draft passage 80 below described filter plate 70, described air draft passage 80 tail end is connected with air exhauster 81.

During use, material is advanced forward by material conveyer belt 10, the feed end accelerating conveyer belt 20 is dropped to subsequently from the discharge end of material conveyer belt 10, owing to accelerating conveyer belt 20 speed, material is due to self inertia, the parabola of certain track can be presented when departing from and accelerating conveyer belt 20 discharge end, because the impurity density in waste plastic is large compared with plastics, heavier mass, thus the inertia of impurity self is larger, the side near the first collecting bin 40 on triangle conveyer belt 30 can be left, realize the separation of impurity, and the drop point on triangle conveyer belt 30 of the light plastics of the less quality of density can near the second collecting bin 41, facilitate the collection of plastics, the effect of scraper plate 61 is under some being attached to the material scraper on acceleration conveyer belt 20, avoid its accelerated conveyer belt 20 to carry and continue motion, the effect of deep bead 60 is isolated with other parts of other system by the second collecting bin 41, guarantee air exhauster 81 operationally, second collecting bin 41 maintains negative pressure state, filter plate 70 is arranged on bottom the second collecting bin 41, its effect is ensureing under the condition of ventilating, material is focused on the bottom of collecting bin, the effect of air exhauster 81 is in negative pressure state by making in the second collecting bin 41, due to the light weight of plastics, the plastics accelerating to leave between conveyer belt 20 and triangle conveyer belt 30 will move under negative pressure affects in the second collecting bin 41, realize the collection of plastics.

Further, accelerate conveyer belt 20 with electrostatic, described scraper plate 61 is metal material with deep bead 60, described deep bead 60 carries out grounding, conveyer belt 20 is accelerated with electrostatic by allowing, in its traveling process, certain absorption affinity can be produced to plastics, thus after in acceleration, conveyer belt 20 dishes out, shorter when lateral displacement comparatively can not have electrostatic, be more conducive to being separated, corresponding is that scraper plate 61 carries out ground connection with deep bead 60, when it can be made to contact with material, the electrostatic carried by material moves away in time, avoids material to be adsorbed on scraper plate 61 with on deep bead 60.

Further, blower fan 50 is provided with below described triangle conveyer belt 30, described blower fan 50 air outlet is horizontally disposed with, described second collecting bin 41 is disposed with the 3rd collecting bin 42 and the 4th collecting bin 43 away from the side of blower fan 50, between described second collecting bin 41 and the 3rd collecting bin 42, arc-shaped partition 62 is provided with between 3rd collecting bin 42 and the 4th collecting bin 43, the effect of blower fan 50 is to the wind-force of the plastics transverse direction fallen, make unlike material, the plastics of different densities are separated further, according to the difference of plastic material, the lightest plastics of density will drop down onto from the second collecting bin 41 the 4th collecting bin 43 farthest, what density was larger will drop down onto three collecting bin 42 adjacent with the second collecting bin 41, filter plate 70 is provided with bottom 3rd collecting bin 42 and the 4th collecting bin 43, be communicated with air draft passage 80 below filter plate 70, the effect of arc-shaped partition 62 be avoid with plastic contacts process in produce larger frictional force, thus affect plastics and fall to bottom collecting bin.
