The characteristics that the treatment process of waste chip card, smart card is formed according to its material can be with reference to the processing method of electron wastes.Both at home and abroad the processing of electron wastes is all relatively paid attention at present, also formed treatment facility miscellaneous and treatment process.
The FXS waste electron wiring board recycling complete set of equipments of Zhejiang Province Fengli smash equipment Co., Ltd's exploitation, adopted physics method circulation process for separating and recovering, multi-layer combined type turbine to pulverize to dissociate and turbine type ultra micro classification technique, high-pressure electrostatic isolation technics, old circuit board is recycled, the separation accuracy height, organic efficiency is good.
Chinese invention patent ZL200510023785.5 discloses a kind of fragmentation and high-pressure electrostatic separation method of waste printed circuit board on May 2nd, 2007.This method by being ground into a certain size particle, adopts the high-pressure electrostatic method to carry out separating of metallic particles and non-metallic particle waste printed circuit board.Good separating effect, energy consumption is low.
China utility model patent ZL200620044114.7 discloses a kind of waste and old se-drum recovery and processing system on September 19th, 2007.This method is handled by conveyer, disintegrating machine, deduster, magnetic pulley and air washer and is reclaimed waste and old se-drum, the organic efficiency height, and efficiency of dust collection is good, omnidistance non-secondary pollution.
Prior art is handled the generally just simple pulverizing of waste chip card, smart card, but this method can not reclaim wherein value part.And reclaim metal wherein and nonmetally carry out the technology that resources circulation utilizes again and do not appear in the newspapers
Summary of the invention
Blank based on existing waste chip card, smart card recovery processing technique, prior art is handled the difficulty of waste chip card, smart card simultaneously, simple pulverizing can not be reclaimed noble metal wherein, only separates then wasting energy with high-pressure electrostatic by fine grinding, and sub-argument efficient is low.
The present invention solves the problems of the technologies described above the technical scheme that adopts to be: all information in waste chip card, the smart card are thoroughly destroyed, and metal and nonmetallic materials in waste chip card, the smart card get utilization, and comprise following processing step:
(1) waste chip card, smart card are ground into the fragment of certain size;
(2) fragment being carried out eddy current separation is metal fragment and nonmetal fragment;
(3) be powder with metal fragment by the levigate mill of eddy current;
(4) powder is carried out high-pressure electrostatic and be separated into metal dust and non-metal powder;
(5) dust that produces in fine grinding and high-pressure electrostatic separation process is collected by pulse bag type dust collector.
In the above-mentioned processing step, crushing process is preferably in the rotating knife formula plastic breaker and carries out, and assorting room preferably adopts eddy current separator, and two roller secondary high-pressure electrostatic separation are preferably adopted in separation process.
With respect to existing burning disposal technology, process using physical method of the present invention utilizes eddy current separation, high-pressure electrostatic isolation technics, bag-type dust removing system, has realized the safe disposal and the resource recycling of waste chip card, smart card.Pulverizing, vortex flow separation, eddy current mill, high-pressure electrostatic separation, bag-type dusting are combined into the complete technology of a cover.Overall process disposal ability height, organic efficiency height, non-secondary pollution.
