Description
Technical field
The present invention relates to realize the fixing structure of sealing to centrifuge, 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, can not reclaim the etching solution of inefficacy, environment is had a 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 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, because centrifuge is all to adopt electrodynamic type to drive, the centrifugal force producing is very large, need to guarantee the sealing of its inside, in order to avoid causing material to splash.
Summary of the invention
The object of the invention is to overcome the shortcoming and defect of above-mentioned prior art, provide and can realize the fixing structure of sealing to centrifuge, this structural principle is easy, low cost of manufacture, good fixing effect, convenient disassembly, can effectively to the end cap of centrifuge and body, realize sealing and fixing, centrifuge can not spilt inner material in the process of work, improved working environment, guaranteed operating personnel's safety simultaneously.
Object of the present invention is achieved through the following technical solutions: can realize the fixing structure of sealing to centrifuge, comprise fixed block, described fixed block one end indent forms the groove being communicated with both sides, the other end is provided with handle, on fixed block, be provided with the rotational pin that runs through fixed block and can freely rotate, rotational pin is connected with U-shaped screw rod, and the two ends of U-shaped screw rod are connected with the two ends of rotational pin respectively.
Further, described rotational pin is vertical with handle to be arranged, and handle is arranged on the outside of U-shaped screw rod away from one end of fixed block.
Further, on the sidewall at the two ends of described rotational pin, be symmetrically arranged with respectively plane, the two ends of U-shaped screw rod are provided with thread segment, and thread segment is all vertically through corresponding plane, on the outer wall of thread segment, be sheathed with nut, described nut is separately positioned on the both sides of rotational pin, and with plane contact corresponding on rotational pin.
Further, on described fixed block, be provided with the through hole that runs through fixed block, and the inwall of through hole through-going recess, the center line of described through hole is parallel with the center line of rotational pin.
In sum, the invention has the beneficial effects as follows: this structural principle is easy, low cost of manufacture, good fixing effect, convenient disassembly, can effectively realize sealing and fixing to the end cap of centrifuge and body, and centrifuge can not spilt inner material in the process of work, improve working environment, guaranteed operating personnel's safety simultaneously.
