Description
Technical field
The utility model relates to fixed structure, especially relates to the fixed structure based on centrifugation apparatus inside, belongs to the environmental protection reclaimer.
Background technology
The typical process of printed circuit board (pcb) processing adopts " graphic plating method ".Namely then elder generation's (being the visuals of circuit) preplating one deck slicker solder resist layer on the outer Copper Foil part that needs to keep of plate erodes remaining Copper Foil with chemical mode, is called etching.The 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 mainly is applicable to graphic plating metal resist layer, such as plated with gold, nickel, leypewter, the etching of the printed board of tin-nickel alloy and tin, its characteristics are that etch-rate is fast, and lateral erosion is little, molten copper ability is high, etch-rate is easily controlled, and in the printed circuit board production process, etching is a very important technical process, needing to use a large amount of etching solutions, therefore also is an operation that produces the severe contamination source.Traditional governance approach is: specify the company that qualification is arranged to reclaim by environmental administration, adopt simple way, wherein contained copper is processed into copper sulphate, then process slightly discharging.This significant wastage that has not only caused resource is (in every kilolitre alkaline etching liquid except cupric, also have the ammonium chloride more than 240 kilograms, about 30 kilograms the chemical substances such as liquefied ammonia), and waste liquid does not obtain real radical cure, has therefore formed the transfer of pollution sources.
Barrier film is made by inert material, such as the asbestos diaphragm of the medium-term and long-term use of chlorine industry.But the asbestos diaphragm unstable properties when containing calcium, magnesium addition in the salt solution, easily generates precipitation of hydroxide in barrier film, reduces transmitance; In higher temperature with under the electrolyte effect, also can expand, get loose.Can in asbestos, add resin as reinforcing material for this reason, or make micro-pore septum take resin as main body, all be improved aspect stability and the mechanical strength.Alkaline etching liquid is reclaimed to discuss by hazardous waste and carries out resource recovery copper at present, produce the copper sulphate product, its processing procedure need to consume a large amount of reagent, produce a large amount of washes, or the product purity that obtains is inadequate, and can not the Direct Regeneration etching solution, economic benefit is low, can not reclaim the etching solution of inefficacy, environment there is certain impact, and cause the energy resource consumption of transportation and cost to increase, engendered in the market the equipment of processing etching waste liquor with electrochemical principle, etching waste liquor can not only be recycling for a long time after treatment, and can also obtain considerable income-cathode copper, the copper powder that electrolysis goes out is in the liquid-solid mixture, need in centrifuge, realize separating, centrifugal is exactly the powerful centrifugal force that utilizes the centrifuge rotor High Rotation Speed to produce, the sinking speed of particle in the accelerating liquid, the separating substances of different sedimentation coefficients and buoyant density in the sample is opened, traditional centrifuge internal structure is complicated, maintenance difficult, the efficient of centrifuge dripping is low, and its inner fixed effect is poor, when carrying out centrifuge dripping, inner stoste is often mixed, causes the centrifugal effect of copper powder bad, the purity of copper powder is inadequate, can't store and follow-up use.

The purpose of this utility model is achieved through the following technical solutions: based on the fixed structure of centrifugation apparatus inside, comprise filter cylinder, described cartridge interior is provided with retainer ring, evenly be provided with several fixing holes on the wall of filter cylinder, be provided with the fixed head that several are U-shaped structure on the retainer ring, and the two ends of fixed head all are arranged on the retainer ring, be provided with the latch that is L-type on the described retainer ring, and latch one end passes simultaneously, and to enter into corresponding fixing hole behind the space between fixed head and the retainer ring inner.
Further, be provided with shell on the outer wall of described filter cylinder, described outer casing bottom center is provided with rotating seat, rotating seat is connected with the motor that is arranged on housing exterior, filter cylinder is arranged on the rotating seat, and is provided with several through holes on the wall of filter cylinder, and fixing hole is arranged on the top of through hole.
Further, described cartridge interior is provided with filter screen, is connected with the inwall of retainer ring around the filter screen.
Further, be provided with several boss on the described retainer ring, correspondence is provided with fixing hole on the filter screen, described boss passes corresponding fixing hole, 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 passes installing hole.
Further, the upper surface of described retainer ring is provided with several suspension ring, and suspension ring evenly distribute along the center of retainer ring.
In sum, the beneficial effects of the utility model are: this fixed structure principle is easy, stress deformation is little, latch by even setting, can stably the equipment of drying and filter cylinder be fixed, in the process that dries, effectively the moisture in the copper powder liquid be dried, obtain the high copper powder of purity, for subsequent handling is provided convenience.
