By aforementioned intelligent control panel setting relevant parameter, realize the fully automatic operation of this intelligently filters Controlling System; In Electroplating Production, dust may be had in electroplate liquid, also the burr that hanger drops is had, anode also may produce the anode sludge in addition, these impurity all likely waft and form flaw to parts to be plated, utilize this filtration Controlling System to carry out circulating filtration electroplate liquid, its filtering accuracy≤0.1um, can reduce the generation of these type of substandard products.
Incorporated by reference to
fig. 1with
fig. 2shown in, in this intelligently filters Controlling System, strainer 40 is configured with pressure transmitter, judge that strainer is the need of cleaning by pressure transmitter sensed pressure, its sensed pressure is less than when setting numerical value (being such as less than 2bar), filtering system is normally run, and adopts circulating filtration mode to filter electroplate liquid; Now, water intaking valve BV01, product water valve BV03 open, and all the other valves then cut out;
When sensed pressure is when setting more than numerical value (such as more than 2bar), illustrate that strainer 40 produces certain dirt and blocks up, need to start wash procedure, circulating filtration runs the pressure range (or time of setting) reaching pre-front setting, circulating filtration program stopped runs, system automatically can enter recoil/cleaning and wash function, and wash procedure has the following steps:
(a) before washing, first carry out first time emptying process (
fig. 2shown emptying 1-1), open pressurized air, residue filtrate in strainer 40 is drained back in electroplate liquid medicine groove 10 through the filtrate outlet of filter 40, the filtrate (electroplate liquid) remained is avoided to run off with scavenging solution and cause waste, now, product water valve BV03, gas setting-out valve BV07 open, and all the other valves then cut out;
After the step (a) of described wash procedure, can carry out again as required emptying (
fig. 2shown emptying 1-2), open pressurized air, through filter 40, residue filtrate in strainer 40 is treated that filtrate inlet is discharged, and drain back to after being filtered by filter stick 50 in electroplate liquid medicine groove 10, further the electroplate liquid remained in strainer 40 is carried out emptying, to reach the object reclaiming electroplate liquid as far as possible, now, gas setting-out valve BV07, second emptying valve BV12 open, and all the other valves then cut out;
(b) closes compression air, filtration pump 50 carries medicine wash water to enter in strainer 40 to carry out wash cycles to carry out the cleaning of medicine wash water circulation forward to strainer 40; (selection of cleaning agent will see what the pollutent of this kind of plating solution is), now, second emptying valve BV02, cleaning reverse flow valve BV09 open, and all the other valves then cut out;
C () clear Xian reaches the presetting time, open pressurized air to carry out mixing wastewater with air from the inside to the outside and to recoil Xian, mixing wastewater with air forms cleaning foam, the time of its recoil Xian can be set to 30s, now, second emptying valve BV02, cleaning reverse flow valve BV09 open, and during this period, gas back flushing valve BV08 intermittent type starts, and its number of starts can be changed by sequence of control;
D () recoil is after Xian reaches the presetting time, stop mixing wastewater with air recoiling after Xian, open pressurized air, carry out second time emptying process (
as Fig. 2shown in emptying 2), the medicine wash water inherent filtration device 40 retained in strainer 40 treated that filtrate inlet flows back to clearly in Xian's groove 20, then by emptying for clear Xian's groove 20, medicine wash water reclaimed, avoid waste medicine wash water, now, second emptying valve BV02, gas setting-out valve BV07 open, and all the other valves then cut out;
E () aforementioned medicine wash water is emptying after, because remaining medicine wash water in strainer 40, directly transport
guildthe medicine wash water of part is brought in electroplate liquid medicine groove 10, so cleaning terminates rear needs carry out reverse flushing with pure water to strainer 40, further strainer 40 is cleaned and scavenging solution is rinsed well, avoiding polluting electroplate liquid; Namely aforementioned clear Xian's groove 20 is emptying fills clear water afterwards to it, and carry out gas and clean clear water mixing recoil Xian 30s to strainer 40, now, pure water backwash valve BV04, vent valve BV06, gas back flushing valve BV08 open, and all the other valves then cut out;
F () has cleaned, rinse and need this washing fluid emptying after terminating, avoid washing fluid to bring in electroplate liquid medicine groove 10, herein, by the washing fluid inherent filtration device 40 in strainer 40 treated that filtrate inlet drains into discharge of wastewater, emptying by strainer 40,
as Fig. 2shown in emptying 3; Now, gas setting-out valve BV07, first emptying valve BV11 open, and all the other valves then cut out; Complete aforementioned wash procedure, reach setting-up time in advance, system can enter normal filtration program automatically.
It should be noted that, aforementioned air-water backwashing frequency number of times, can be arranged as required flexibly, and such as: medicine wash water circulation flushing 300 seconds, when medicine is washed, air purge number of times is 5 times, namely carries out an air purge by every 60 seconds in 300 seconds; And, the surge time between These steps, also can arrange flexibly as required, exhaust, elimination foam etc. should be needed in good time.
When the medicine wash water in rinse bath 20 lost efficacy, needed discharge medicine wash water, opened clean-drain valve BV10, the medicine wash water lost efficacy was discharged through cleaning discard solution discharge port, the 13 pipeline, discharge of wastewater mouth, discharge of wastewater mouth can connect waste water processing station (
as Fig. 2in shown in emptying 4).
Design focal point of the present invention is, its mainly setting such as emptying reuse pipeline, first emptying valve, additional filtration unit, the electroplate liquid remained in strainer is carried out recycle to electroplate liquid medicine groove, solve in conventional art and be worth expensive electroplate liquid and drain with waste liquid and the problem of wasting, decrease enterprise's production cost, save water source, decrease waste water generation.
The above, it is only preferred embodiment of the present invention, not technical scope of the present invention is imposed any restrictions, thus every above embodiment is done according to technical spirit of the present invention any trickle amendment, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
