Description
Technical field
The utility model relates to a kind of tripping device, and copper powder reclaims and discharge water decontamination cycle device in the discharge water of outstanding finger mark printed circuit board production process.
Background technology
In the printed circuit board (PCB) production process, the discharge water that two sections engineerings are arranged is not contain acidic substance, the copper powder that but contains high price and a large amount of moisture content, the one, polish-brush machine discharge water, the one, rinsing machine discharge water.
Polish-brush machine significant feature is with copper coin surface high speed polish-brush roughening, and anti-welding lacquer is adhered to easily, and therefore the polish-brush water copper content of being discharged is many certainly, the value height of recovery.Rinsing machine discharge water copper content is then less, unless the degree height that recycle-water purifies, the value that reclaims is not only not high, even be the burden of wastewater treatment.The handling of every degree water is higher than charge for water, if together with the water rate of tap water, then rinsing machine almost is more than 2.2 times of general water rate with water rate.
Polish-brush machine discharge water the earliest also is not the very high epoch in environmental consciousness, and the copper powder way of recycling all is to adopt the precipitator method, promptly utilizes the weight of copper powder, reclaim in the mode of nature, so the still residual a large amount of copper powder of discharge water, produce a large amount of waste water.So far still have the partly mode of factory's employing natural sedimentation, allow copper powder be deposited in bottom land.
But gradually, the cost that copper powder and water resources reclaim along with the price of copper and water resources rises, and environmental consciousness comes back, and copper powder reclaims becomes another principal income of circuit card industry, reclaims machine so each polish-brush machine begins to match a copper powder.Except reclaiming copper powder, because the polish-brush machine makes the less demanding of water, the water after the recovery can use in recirculation, and the standard that has therefore brought up copper powder recovery machine and become the polish-brush machine is equipped with, even become and reclaim the dealer equipment initiatively is provided, plant the industry form to exchange other that reclaim copper powder for.
So for many years, the retrieving arrangement of printed circuit board (PCB) is still kept such pattern, and as shown in Figure 1, copper powder of polish-brush machine 1 configuration reclaims machine 3, and the discharge water of rinsing machine and bottom of gullet draining are handled without copper powder recovery machine, directly drain into wastewater trough.The water that copper powder reclaims machine 3 recovery only is enough to supply partly water of polish-brush machine, must add new tap water and replenish.Reason is: existing copper powder reclaims machine not only can't make copper powder do complete recovery, in the process of recovery machine running, moisture content runs off because of the high temperature evaporation that produces that runs up, and the copper content of water quality is too high, must partly drain into wastewater trough and deal with in addition, and can't move and make other purposes.
The copper powder way of recycling of prior art is divided into two kinds haply, and a kind of is centrifugal, and another kind then is a bag filter formula.Its maximum common ground is: the water quality copper content after the filtration is still high, and only filters from the water of polish-brush machine discharging.
Centrifugal copper powder reclaims the main function of machine, be to utilize its ultracentrifugal effect, make the polish-brush machine discharge water that contains copper powder when entering the recovery machine, be attached to the inwall of recycling bin filtering element (cartridge) owing to high speed centrifugation, moisture content then flows to catchment port, after adding partly tap water dilution and lowering the temperature, send the polish-brush machine back to and recycle.
Centrifugal copper powder reclaims machine in order to reach the effect of copper powder and water sepn; the result of high speed centrifugation running; because be close to recycling bin filtering element (cartridge) inwall, must just have only the polish-brush machine of waiting until and recovery machine to shut down simultaneously just and can clear up except copper powder with outside a large amount of tap water cleanings.And centrifugal recovery machine rises because of the high speed rotating temperature, causes the aqueous vapor evaporation, and moisture reduces, and must constantly replenish the polish-brush machine and make water, makes the original meaning of water saving lose to the greatest extent.And running up causes the easy fault of board, the starting electric power after the shutdown, all make centrifugal recovery machine except cleaning a bag filter formula reclaim machine easily, shutdown, fault, with water consumption etc., problem is heavy.And the environment of lack of water makes the circuit card industry more be attacked in the front and the rear.
Through measuring with real-world operation, the current consumption that each centrifugal copper powder reclaims machine is all high than bag filter formula recovery machine, and every day, water loss was about 20～30M
3, about 2.2 of the filtering element (cartridge) that must change every day, 100,000 yuan of the annual about New Taiwan Currencies of upkeep cost; the time of every recovery machine cleaning is about 1.2 hours, about 15～30 kilograms of the copper powder of handling every day, and annual number of faults is 8 times; because shut down the production capacity that reduces, every year is more up to about 70,000.
Bag filter formula copper powder recovery machine utilizes pump that polish-brush water is squeezed in the box-shaped filter bag, treat that water flows out from filter bag after, returning the polish-brush machine with pump again recycles, as M259640 number " copper powder filter " novel patent of TaiWan, China, waste water after filter bag filters can be discharged via water outlet by after the filter bag, equipment for the cleaning circuit plate recycles, the shortcoming that does not have centrifugal recovery machine water temperature to rise and run up really.Just box-shaped filter bag bond area is limited, and must open again and again, and could clear up after must shutting down so that clear up copper powder, be a big problem really.
Because it is limited that at present all copper powders reclaim the treatable amount of machine institute, often cleaning and maintenance again, therefore, no matter be centrifugal or bag filter formula, very typical method is exactly: a polish-brush machine is joined a copper powder and is reclaimed machine, and configuration multidigit special messenger is engaged in the work of cleaning copper powder and maintenance board, stops to avoid the polish-brush machine comprehensively.And the rinsing machine discharge water is without recovery, and major cause is: the water quality of recycle-water can only be partly used for the polish-brush machine, and too high copper content can't be used for rinsing machine.And the polish-brush machine still needs in addition to replenish tap water, even and the additional part of recycle-water is all unsuitable as the sanitation bath water, so the rinsing machine discharge water is not all included recovery system in.
And will clear up copper powder the time, except copper powder reclaims machine must shut down, the polish-brush machine also must and then be shut down.Such mode of operation, waste on processing procedure and production capacity descended, the failure rate of board also significantly improved.Therefore the production scene must often dispose the work that the multidigit special messenger is engaged in cleaning copper powder and maintenance board, increases cost.And water resources is only the most instant problem of this copper powder recovery technology.。
