Circuit board recycling equipment a circuit board crushing and recycling system structure design is reasonable, through the crusher and shredder to crush and shred circuit boards, crushing through the analysis machine separation, separation of dust and fiber powder in the end of the set of high pressure fan attraction, the diversion of transport to the collector and pulse dust collector, to avoid the accumulation of powder in the pipeline, the analysis machine separation of the coarse mixture through the hoist The coarse material after the separation of the analyzer enters the airflow sieve, the coarse material after the separation of the airflow sieve enters the pulverizer for processing, the fine material after the separation of the airflow sieve enters the specific gravity sieve for separation, the heavier material enters the electrostatic sorter through the elevator to separate the metal and epoxy ester, the lighter material is separated and recovered from the fiber powder and dust through the collector and pulse dust collector under the attraction of the high-pressure induced draft fan set at the end. The whole system has a high degree of fine material recovery, good copper-plastic separation of circuit board processing, reducing the pollution of the environment by residues, reasonable structure design, and strong practicality.
Circuit board recycling equipment processing process: the crusher can crush the circuit board, crushed to a particle size of 2-3 centimeters, crushed circuit board into the crusher, the crusher to crush the circuit board, crushed to about 20 mesh, crushed circuit board into the analyzer, the analyzer to crush the material for wind selection, the material in the resin powder, metal, dust, fiber powder for separation, dust and fiber powder is high-pressure fan into the collector. The dust and fiber powder are sucked into the collector by the high-pressure induced draft fan, and the resin powder and metal enter the airflow sorting screen through the elevator Ⅰ.
The collector collects the fiber powder, and the collected fiber powder is discharged through the fiber powder outlet.
The air flow sieve screens the resin powder and metal, the resin and metal that are not separated are returned to the crusher for re-crushing, and the separated resin powder and metal are separated in the specific gravity sieve.
The specific gravity sieve can sort the resin powder and metal by specific gravity, because the weight of metal is greater than the weight of resin powder, metal will be sorted to one side and resin powder will be sorted to the other side, so as to achieve the separation of metal and resin powder, which is a very advanced sorting technology in China at present, and can sort the metal to more than 99%.
Electrostatic sorter, also known as high pressure electrostatic sorter, can separate the small particles of metal and resin powder contained in the tailing material after the specific gravity sieve, the principle of high pressure electrostatic sorter is: the input power is adjusted to 100,000 volts of high voltage by the transformer, forming a high pressure magnetic field, the conductive metal adsorption, so that the metal and non-metal separation.
High-pressure induced fan will analyze the machine and specific gravity sieve screening light material into the collector, after the collector into the pulse dust collector, under the attraction of the high-pressure induced fan, high-pressure airflow on fiber powder and dust suction and attraction function, in the collector and pulse dust collector will inevitably exist in the bend, high-pressure induced fan is located at the end of the advantage of the material suction in front of the suction, the material through the bend when If the induced draft fan is located in the front of the collector, it is equivalent to the material into the collector and pulse dust collector, the induced draft fan gives the material a backward blowing force, the blowing force will be relatively weakened when the material passes through the bend, the material will easily stay or accumulate in the inner wall of the bend, so that the material collection is not che bottom; the collector discharges the fiber powder through the fiber powder port, and the ultra-fine fiber or other dust will be discharged through the fiber powder port. Ultra-fine fiber or other dust is processed and purified through the pulse dust collector to prevent the discharged gas and dust from polluting the air, and the processed ultra-fine dust is discharged through the discharge port on the pulse dust collector.
Circuit board recycling equipment after the above multiple screening and processing, can be fully used circuit board treatment thoroughly, high recovery rate, environmental pollution is small, strong practicality.
