Description
Technical field
The utility model relates to and can realize the structure that sealing is fixing to centrifuge, belongs 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 ".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 controlled easily, 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 medium-term and long-term asbestos diaphragm that uses of chlorine industry.But the asbestos diaphragm unstable properties when containing calcium, magnesium addition in the salt solution, generates precipitation of hydroxide easily 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, because centrifuge all is to adopt electrodynamic type to drive, the centrifugal force that produces is very large, needs to guarantee the sealing of its inside, in order to avoid causing material to splash.
The utility model content
The purpose of this utility model is to overcome the shortcoming and defect of above-mentioned prior art, provide and to realize the structure that sealing is fixing to centrifuge, this structural principle is easy, low cost of manufacture, good fixing effect, convenient disassembly, can effectively realize sealing and fixing to end cap and the body of centrifuge, so that centrifuge can not spill the material of inside in the process of work, improved working environment, guaranteed simultaneously operating personnel's safety.
The purpose of this utility model is achieved through the following technical solutions: can realize the structure that sealing is fixing to centrifuge, comprise fixed block, described fixed block one end indent forms the groove that is communicated with both sides, the other end is provided with handle, be provided with the rotational pin that runs through fixed block and can freely rotate on the fixed block, 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 an end of fixed block.
Further, be symmetrically arranged with respectively the plane on the sidewall at the two ends of described rotational pin, the two ends of U-shaped screw rod are provided with thread segment, and thread segment all vertically passes corresponding plane, be sheathed with nut on the outer wall of thread segment, described nut is separately positioned on the both sides of rotational pin, and with rotational pin on corresponding plane contact.
Further, be provided with the through hole that runs through fixed block on the described 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 beneficial effects of the utility model are: this structural principle is easy, low cost of manufacture, good fixing effect, convenient disassembly can effectively be realized sealing and fixing to end cap and the body of centrifuge, so that centrifuge can not spill the material of inside in the process of work, improve working environment, guaranteed simultaneously operating personnel's safety.
