Description
Technical field
The present invention relates to and the fixing structure of sealing is realized to centrifuge, belong to the environmental protection equipment to etching solution process.
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, because centrifuge is all adopt electrodynamic type to drive, the centrifugal force produced is very large, need the sealing ensureing its inside, in order to avoid causing substance splash.
Summary of the invention
The object of the invention is to the shortcoming and defect overcoming above-mentioned prior art, there is provided and can realize the fixing structure of sealing to centrifuge, this structural principle is easy, low cost of manufacture, good fixing effect, convenient disassembly, effectively can realize sealing and fixing to the end cap of centrifuge and body, the material of inside can not be spilt by centrifuge in the process of work, improve working environment, ensure that the safety of operating personnel 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 be communicated with both sides, the other end is provided with handle, fixed block is provided with and runs through fixed block and the rotational pin that 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, the sidewall at the two ends of described rotational pin is symmetrically arranged with plane respectively, the two ends of U-shaped screw rod are provided with thread segment, and thread segment all passes perpendicularly through corresponding plane, the outer wall of thread segment is sheathed with nut, described nut is separately positioned on the both sides of rotational pin, and the plane contact corresponding with on rotational pin.
Further, described fixed block is provided with the through hole running through fixed block, and the inwall of through hole through-going recess, the center line of described through hole and the centerline parallel 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, effectively can realize sealing and fixing to the end cap of centrifuge and body, the material of inside can not be spilt by centrifuge in the process of work, improve working environment, ensure that the safety of operating personnel simultaneously.
