Description
Technical field
The present invention relates to fixed structure, especially relate to the fixed structure based on interior of centrifugal device, belong to environmental protection reclaimer.
Background technology
The typical process of printed circuit board (pcb) processing adopts " graphic plating method ".Namely elder generation's (being the visuals of circuit) preplating one deck slicker solder resist layer in the outer Copper Foil part that need retain of plate, then chemically erodes remaining Copper Foil, is called etching.PCB etching is divided into alkalescence and acid two kinds, and one is hydrochloric acid hydrogen peroxide system (acidity); Two is ammonium chloride ammonia-water systems (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, and lateral erosion is little, molten copper ability is high, etch-rate easily controls, and in printed circuit board production process, etching is a very important technical process, needing to use a large amount of etching solutions, is therefore also an operation producing severe contamination source.Traditional governance approach is: being specified by environmental administration has the company of qualification to reclaim, and adopts simple way, wherein contained Copper fabrication is become copper sulphate, then processes discharge slightly.This significant wastage not only causing resource is (in every kilolitre alkaline etching liquid except cupric, also has the chemical substance such as the ammonium chloride of more than 240 kilograms, the liquefied ammonia of about 30 kilograms), and waste liquid does not obtain real radical cure, because which form the transfer of pollution sources.
Barrier film is made by inert material, the asbestos diaphragm of use as medium-term and long-term in chlorine industry.But asbestos diaphragm unstable properties, when containing calcium, magnesium addition in salt solution, easily generating precipitation of hydroxide, reducing transmitance in barrier film; In higher temperature with under electrolyte effect, also can expand, get loose.Resin can be added as reinforcing material in asbestos for this reason, or be that main body makes micro-pore septum with resin, all be improved in stability and mechanical strength.Current alkaline etching liquid reclaims business by hazardous waste and carries out resource recovery copper, produce copper sulphate product, its processing procedure needs to consume a large amount of reagent, produce a large amount of washes, or the product purity obtained is inadequate, and can not Direct Regeneration etching solution, economic benefit is low, the etching solution of inefficacy can not be reclaimed, environment is had a certain impact, and cause the energy resource consumption of transportation and cost to increase, engender the equipment processing etching waste liquor by electrochemical principle in the market, etching waste liquor can not only recycle for a long time after treatment, and considerable income-cathode copper can also be obtained, the copper powder that electrolysis goes out is in liquid-solid mixture, need to realize in centrifuges being separated, centrifugal is exactly the powerful centrifugal force utilizing centrifuge rotor High Rotation Speed to produce, the sinking speed of particle in accelerating liquid, the separating substances of sedimentation coefficient different in sample and buoyant density is opened, traditional centrifuge internal structure is complicated, maintenance difficult, the efficiency of centrifuge dripping is low, and the fixed effect of its inside is poor, when carrying out centrifuge dripping, inner stoste is often mixed, cause the centrifugal effect of copper powder bad, the purity of copper powder is inadequate, cannot carry out storing and follow-up use.
Summary of the invention
The object of the invention is to the shortcoming and defect overcoming above-mentioned prior art, fixed structure based on interior of centrifugal device is provided, this fixed structure principle is easy, stress deformation is little, by the latch evenly arranged, can stably drying equipment and filter cylinder be fixed, carrying out in the process dried, effectively the moisture in copper powder liquid is dried, obtain the copper powder that purity is high, for subsequent handling is provided convenience.
Object of the present invention is achieved through the following technical solutions: based on the fixed structure of interior of centrifugal device, comprise filter cylinder, described cartridge interior is provided with retainer ring, the wall of filter cylinder is evenly provided with several fixing holes one, retainer ring is provided with the fixed head of several U-shaped structures, and the two ends of fixed head are all arranged on retainer ring, described retainer ring is evenly provided with the latch that several are L-type, and one end of each latch is all inner through entering into corresponding fixing hole one behind the space fixed head and retainer ring.
Further, the outer wall of described filter cylinder is provided with shell, described outer casing bottom center is provided with rotating seat, rotating seat is connected with the motor being arranged on housing exterior, filter cylinder is arranged on rotating seat, and the wall of filter cylinder is provided with several through holes, and fixing hole one is arranged on the top of through hole.
Further, described cartridge interior is provided with filter screen, and the surrounding of filter screen is connected with the inwall of retainer ring.
Further, described retainer ring is provided with several boss, on filter screen, correspondence is provided with fixing hole two, described boss is through corresponding fixing hole two, the bottom of described filter cylinder is provided with support column, and support column is arranged on retainer ring inside, the center of filter screen is provided with installing hole, and support column is through installing hole.
Further, the upper surface of described retainer ring is provided with several suspension ring, and suspension ring are uniformly distributed along fixing Ring current distribution.
In sum, the invention has the beneficial effects as follows: this fixed structure principle is easy, stress deformation is little, by the latch evenly arranged, stably drying equipment and filter cylinder can be fixed, carry out in the process dried, effectively the moisture in copper powder liquid be dried, obtain the copper powder that purity is high, for subsequent handling is provided convenience.
