Description
Technical field
The present invention relates to centrifugation apparatus, especially relate to based on copper powder is carried out to separated centrifugation apparatus, belong to the environmental protection equipment that etching solution is processed.
Background technology
The typical process of printed circuit board (pcb) processing adopts " graphic plating method ".(being the visuals of circuit) preplating one deck slicker solder resist layer in the Copper Foil part that first needs to retain at plate skin, then erodes remaining Copper Foil with chemical mode, is called etching.PCB etching is divided into alkalescence and two kinds of acidity, and one is hydrochloric acid hydrogen peroxide system (acidity); Two is ammonium chloride ammoniacal liquor system (alkalescence).Alkaline etching liquid is mainly applicable to graphic plating metal resist layer, as plated with gold, nickel, leypewter, the etching of the printed board of tin-nickel alloy and tin, its feature is that etch-rate is fast, lateral erosion is little, molten copper ability is high, etch-rate is easily controlled, and in printed circuit board production process, etching is a very important technical process, need to use a large amount of etching solutions, be also therefore an operation that produces severe contamination source.Traditional governance approach is: by environmental administration, specified and had the company of qualification to reclaim, adopt simple way, wherein contained copper is processed into copper sulphate, then process slightly discharge.This has not only caused the significant wastage of resource (in every kilolitre alkaline etching liquid except cupric, also have 240 kilograms of above ammonium chlorides, the chemical substances such as liquefied ammonia of 30 kilograms of left and right), and waste liquid does not obtain real radical cure, therefore formed the transfer of pollution sources.
Barrier film is made by inert material, as the asbestos diaphragm of the medium-term and long-term use of chlorine industry.But asbestos diaphragm unstable properties while containing calcium, magnesium addition in salt solution, easily generates precipitation of hydroxide in barrier film, reduce transmitance; In higher temperature with under electrolyte effect, also can expand, get loose.Can in asbestos, add resin as reinforcing material for this reason, or take resin and make micro-pore septum as main body, aspect stability and mechanical strength, all be improved.Alkaline etching liquid carries out resource recovery copper by hazardous waste recovery business at present, produce copper sulphate product, its processing procedure need to consume a large amount of reagent, produce a large amount of washes, or the product purity obtaining is inadequate, and can not Direct Regeneration etching solution, economic benefit is low, the etching solution that can not reclaim inefficacy, has a certain impact to environment, and causes the energy resource consumption of transportation and cost to increase.Engendered in the market the equipment of processing etching waste liquor by electrochemical principle, etching waste liquor can not only recycle for a long time after treatment, and can also obtain considerable income-cathode copper, the copper powder that electrolysis goes out is in liquid-solid mixture, need in centrifuge, realize separated, centrifugal is exactly the powerful centrifugal force that utilizes centrifuge rotor High Rotation Speed to produce, the sinking speed of particle in accelerating liquid, the separating substances of different sedimentation coefficients and buoyant density in sample is opened, traditional centrifuge internal structure is complicated, maintenance difficult, the efficiency of centrifuge dripping is low, cause the centrifugal effect of copper powder bad, the purity of copper powder is inadequate, cannot store and follow-up use.
Summary of the invention
The object of the invention is to overcome the shortcoming and defect of above-mentioned prior art, provide based on copper powder is carried out to separated centrifugation apparatus, this centrifugation apparatus is simple in structure, easy to operate, centrifugal efficiency is high, can effectively to the precipitation copper powder in etching solution, filter drying, guarantee the purity of copper powder, for the subsequent storage of copper powder with use good environment is provided.
Object of the present invention is achieved through the following technical solutions: based on copper powder is carried out to separated centrifugation apparatus, the shell that comprises inner hollow, described outer casing bottom center is provided with rotating seat, rotating seat is connected with the motor that is arranged on housing exterior, on rotating seat, be provided with filter cylinder, be provided with several through holes on the wall of filter cylinder, described cartridge interior is provided with retainer ring and filter screen, described retainer ring and filter cylinder are fixed, and the surrounding of filter screen is connected with the inwall of retainer ring.
Further, the bottom of described filter cylinder is provided with support column, and support column is arranged on retainer ring inside, and the center of filter screen is provided with installing hole, and support column is through installing hole.
Further, be provided with several boss on described retainer ring, on filter screen, correspondence is provided with fixing hole, and described boss is through corresponding fixing hole.
Further, the upper surface of described retainer ring is provided with several suspension ring, and suspension ring are uniformly distributed along the center of retainer ring.
Further, the center line of described support column and the center line of filter cylinder on same straight line, the center line of filter cylinder and the center line of retainer ring all with the center line of rotating seat on same straight line.
In sum, the invention has the beneficial effects as follows: this centrifugation apparatus is simple in structure, easy to operate, centrifugal efficiency is high, can effectively to the precipitation copper powder in etching solution, filter drying, guarantee the purity of copper powder, for the subsequent storage of copper powder with use good environment is provided.
