Abstract
The utility model relates to waste PCB(printed circuit board)recovery, regeneration and recycling technical field and in particular to a high-voltage electrostatic sorting and feeding device for waste PCB grains, which mainly comprises a feed hopper, a feeding roller, an corona electrode and a static electrode. An electromagnetic vibrator is arranged at the outlet of the feed hopper to drive the material in the feed hopper and a material chute to shake together. Based on resonance principle, the high-voltage electrostatic sorting and feeding device enables the feed hopper and the material chute to shake at the same time, and the arch breaking ability to sticky material is remarkably reduced, thereby avoiding blockage and arch-building phenomena in the feeding process, therefore, the material can be discharged smoothly from the outlet. The high-voltage electrostatic sorting and feeding device has the advantages of small volume, long service life, small electricity consumption, simple structure and convenient installation. The vibration amplitude of the electromagnetic vibrator is adjustable and the adjustment can be realized by adjusting the current. Therefore, the high-voltage electrostatic sorting and feeding device has strong practicability.

Background technology
Since the nineties, being core with the electronic computer, is that whole electronics industry is also advanced by leaps and bounds under the support that develops rapidly of the electronics and information industry of relying on microelectric technique.Along with the continuous progress of science and technology and continuing to increase of the market demand, the update speed of electronic product and equipment is also in continuous quickening.The U.S. scrapped 3,150,000 PCs in 2004; Europe electronic waste generation is with the speed increment of annual 3%-5%.Caused the generation of a large amount of electron wastes thus.Printed circuit board (PCB) (PCB) is widely used in various electronic and electrical equipments and equipment as the basis of electronics industry, and its average growth rate is 8.7%.The continuous development of electronics industry and the update of electronic product and equipment must cause the generation of a large amount of discarded printed circuit boards.Discarded printed circuit boards mainly contains two sources: the useless plate that printed circuit board (PCB) in the waste electronic electric equipment and printed substrate manufacturing industry produce.It is reported that printed circuit board (PCB) only discarded in the annual production process in Taiwan is just up to 100,000 tons.
In waste and old printed circuit board, the content of metal is up to 50%, and the rich ore tenor of occurring in nature 3-5% only.Maximum is copper, also has gold, aluminium, nickel, lead, silicon metal etc. in addition, wherein is no lack of rare metal.Have statistics to show, gold content reaches about 1000 grams in the waste and old circuit board per ton.Now, along with technological level improves, cost reduces, and still can extract the gold about 80 grams in the useless circuit board per ton, and market price is roughly equal to about 8,000 yuan.Therefore, " electronic waste ", the metal that wherein contains are tens times even hundred times of natural mineral reserve.
The waste and old printed circuit board resource treatment technique mainly adopts mechanical treatment or several treatment technology to combine at present.Because mechanical treatment is easily realized through engineering approaches, can't produce secondary pollution, this method is favourably welcome.Through the common high-pressure electrostatic method for separating of the mixture (the waste and old circuit board crushed particles contains multiple metal and nonmetal) behind the mechanical treatment.Patent " the high-pressure electrostatic separator of discarded printed circuit boards crushed particles " (Li Jia; Xu Zhenming, patent No. ZL2005 10023788.9), this has invented the high-pressure electrostatic separator of discarded printed circuit boards crushed particles; When the high-pressure electrostatic sorting, adopt the mechanical shock method to feed in raw material, this mechanical shock feed plate bridge joint feed hopper and feeding roller, " obstruction ", " taking arch " phenomenon of causing owing to reasons such as the interior friction of material, deliquescence, charged composition segregations, make material from not discharging smoothly from the feed hopper outlet, the whole production flow process can not normally be carried out, and this apparatus structure is comparatively complicated, and the vibrations size of vibrations feed plate is non-adjustable, limits to its application.
Summary of the invention
The purpose of this utility model is at the prior art above shortcomings, a kind of high-pressure electrostatic sorting feeding device of waste and old printed circuit board particle is provided, reinforced even, controlled in the time of can being implemented in the high-pressure electrostatic sorting with this device, avoid " obstruction ", " taking arch " phenomenon of causing in the reinforced process, make material from discharging smoothly from material outlet.
For achieving the above object, the utility model is to be provided with electromagnetic vibrator on the sidewall at the outlet position of feed hopper, shakes together with the material that drives in feed hopper and the hopper.
Electromagnetic vibrator is installed in outside the bulkhead of feed hopper, according to resonance principle feed hopper and material is shaken together, to the significantly reduction of broken arch ability of viscous material.Avoid " obstructions ", " taking arch " phenomenon of causing in the reinforced process, make material,, have the advantages that the little life-span of volume is long, power consumption is little, simple in structure, easy for installation owing to the employing resonance principle from exporting smooth discharge.
The vibrations size of electromagnetic vibrator has adjustability, can realize by regulating size of current, and is practical.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
The number in the figure explanation, 1 is electromagnetic vibrator; 2 is feed hopper; 3 is feeding roller; 4 is hairbrush; 5 metallic particles for separation; 6 are the non-metallic particle after separating; 7 is corona electrode; 8 is stationary electrode; 9 is metal and non-metal mixture material particle.
The specific embodiment
Consult shown in Figure 1ly, the utility model mainly comprises feed hopper 2, feeding roller 3, corona electrode 7, stationary electrode 8; One or more electromagnetic vibrators 1 are arranged on the feed hopper 2, preferably be arranged on the sidewall at outlet position of feed hopper, so that the material that drives in feed hopper 2 and the hopper shakes together, thereby avoids " obstruction ", " taking arch " phenomenon of causing in the reinforced process, makes material from exporting smooth discharge.
When reinforced, metal after the fragmentation and non-metal mixture material particle 9 are put into feed hopper 2, utilize the traction of material particles 9 deadweights and feeding roller 3, and the vibrations of process electromagnetic vibrator 1, material particles 9 can evenly feed on the surface of feeding roller 3 like this.Material 9 is charged through the high-pressure electrostatic district that corona electrodes 7 are applied, and makes metallic particles 5 and non-metallic particle 6 with different electric charges.8 pairs of metallic particles of stationary electrode 5 produce electrostatic attraction and make its disengaging feeding roller 3 and fall into the metal collecting region; 6 of non-metallic particles are close to feeding roller 3 surfaces, are rotated further, and are fallen by hairbrush 4 brushes at last, fall into nonmetal collecting region.
The utility model is at first at pack into the mixed material of broken circuit board of feed hopper 2, open the outer electromagnetism electromagnetic shaker 1 of bulkhead of feed hopper 2 then, make material produce vibrations, material evenly enters feeding roller 3 through feed hopper 2, be equipped with the high-pressure electrostatic sorting, the realization metal separates with non-metallic particle.
