Abstract
The invention discloses a friction separator of a recovery processing device for painted plastic parts, which is characterized in that the friction separator comprises a rotating shaft, a friction tube which is disposed around the rotating shaft and has two ends fixedly connected with the rotating shaft, and a dedusting sieve plate disposed around the periphery of the friction tube; a friction cavity is formed between the friction tube and the dedusting sieve plate; one end of the friction cavity is a material inlet, and the other end is a material outlet; the rotating shaft is a hollow shaft; one end of the hollow shaft is connected with an air supply mechanism; a plurality of air holes are distributed on the shaft wall of the hollow shaft; a long air outlet is disposed on the friction tube. The invention forms the high-low pressure friction cavity by the coaxial friction tube and the dedusting sieve plate, which realizes stirring friction of painted plastic particles in the cavity, and thus effectively removes paint on the painted plastic surfaces.
Description
Technical field
The present invention relates to a kind of recycling and processing device of scrapping working of plastics, be specifically related to a kind of in recycling and processing device, the friction separator that will paint separates from band lacquer plastic grain surface.
Background technology
At present along with the developing rapidly and trend that the private car recoverable amount is increasing of China's automobile market, damage and junk vehicle produces that to scrap the plastic fittings such as bumper a considerable number of.Bumper surface is difficult to recycling because its peculiar firmly enamelled coating can't be removed, and always as waste disposal, causes environmental pollution for a long time.
Existing method from band lacquer frosting removal paint has laser ablation method and method of chemical treatment, the cost of laser ablation method is too high, chemical treatment method need to be used has corrosive paint stripper, easily cause secondary pollution, and these two kinds of methods all can not thoroughly be removed the paint on particular plastics surface, use to have limitation.Therefore, consider to adopt mechanical means to paint removal, still, the enamelled coating on bumper surface is very firm, how to design a kind of fricting separating device, can effectively remove the paint on band lacquer plastic grain surface, is problem to be solved by this invention.
Summary of the invention
Goal of the invention of the present invention provides a kind of friction separator for band lacquer working of plastics recycling and processing device, stirs friction by being with the lacquer plastic grain in the friction cavity, with effective removal band lacquer plastic grain surface paint.
To achieve the above object of the invention, the technical solution used in the present invention is: a kind of friction separator for band lacquer working of plastics recycling and processing device comprises a rotating shaft, the friction tube that is fixedly connected with rotating shaft around rotating shaft setting and two ends and around the dedusting sieve plate of the periphery setting of described friction tube; Consist of the friction cavity between described friction tube and the dedusting sieve plate, friction cavity one end is charging aperture, and the other end is discharging opening; Described rotating shaft is hollow shaft, and an end of hollow shaft connects wind pushing mechanism, is distributed with a plurality of exhaust vents on the axial wall of hollow shaft, has the air outlet of strip on the described friction tube.
In the technique scheme, at least part of at least part of section perpendicular to hollow shaft, equidistantly do not arrange between the outer wall of described friction tube and described netted dedusting sieve plate.
Described equidistantly the setting refer to, described friction tube is cylindrical, and described dedusting sieve plate is multi-edge column-shaped.
Perhaps, described equidistantly the setting refer to, at least one surface in the inner surface of the outer surface of described friction tube and described netted dedusting sieve plate, is distributed with the friction raised line.
In the technique scheme, be symmetrically arranged with the air outlet of two strips on the described friction tube.
A given preset value makes in the pending plastic grain particle diameter of 90% particle greater than this preset value, the mesh diameter of described dedusting sieve plate more than or equal to this preset value 1/3rd and less than the diameter of this preset value.
Preferred technical scheme, described friction tube is cylindrical, described dedusting sieve plate is hexagon.
More preferably, described friction tube outer surface is distributed with the friction raised line.
Because technique scheme is used, the present invention compared with prior art has following advantages:
1. the present invention utilizes friction tube and dedusting sieve plate to form the high-low pressure friction lumen, so that band lacquer plastic grain can stir friction in cavity, thereby effectively removes band lacquer frosting paint.
2. have two slotted holes at the hollow rotating shaft coaxial friction tube of connection and coaxial friction tube tube wall among the present invention, can concentrate inlet zone, increase gas flow rate, plastic grain is stirred.
