Abstract
The utility model discloses a purifying and recycling device for etching liquid of printed circuit boards. The purifying and recycling device comprises an adsorption trough, a filter machine, a collection tank and a supply box, wherein the etching liquid outlet of an etching trough is connected with the adsorption trough through a pipeline; a conveying pump is arranged on the pipeline between the etching trough and the adsorption trough; the adsorption trough is divided into a front section and a rear section; a plurality of horizontal oil absorbent cotton swabs are arranged in the front section of the adsorption trough; a plurality of longitudinal active carbon columns are arranged in the rear section of the adsorption trough; the rear section of the adsorption trough is connected with the filter machine through a pipeline; the filter machine is connected with the collection tank through a pipeline; the supply box is connected with the collection tank through a pipeline; a supply metering pump is arranged on the latter pipeline between the supply box and the collection tank; the collection tank is connected with the etching liquid inlet of the etching trough through a pipeline. According to the purifying and recycling device, the etching liquid is purified and recycled; the service life of the etching liquid is efficiently prolonged; the discharge amount of waste etching liquid as well as the addition of new etching liquid is reduced. Therefore, the purifying and recycling device brings more economic benefits and environmental protection benefits.
Description
Technical field
The utility model relates to a kind of improved device of printed circuit board (PCB) etching line, and specifically relating to be used for purifying etching solution on a kind of etching line also can be with the device of liquid medicine recycling.
Background technology
Printed circuit board (PCB) (PCB) industry, it is one of heavy polluted industry, printed circuit board industry mainly concentrates on the developing country that comprises China, existing printed circuit board machining process long flow path, etching work procedure wherein is that proportion is maximum in the PCB Production Flow Chart, pollute a more serious link, used etching solution in use for some time in the etching work procedure, owing to wherein can produce the impurity such as some organism that reduce etching solution work-ing life and suspended substance, can affect the activity of etching solution, when the impurity in the etching solution acquires a certain degree, so that etching solution does not meet the etching index, can't continue to use, become spent etching solution, the pollution index of spent etching solution is very high, be typical dangerous liquid refuse, therefore, how prolong the work-ing life of etching solution, reduce the use of new etching solution and the discharging of spent etching solution, be one of big event of studying in the industry always.
The utility model content
In order to overcome defects, the utility model provides a kind of decontamination cycle reusing appts of printed circuit board (PCB) etching solution, the decontamination cycle reusing appts of this printed circuit board (PCB) etching solution can be removed the pollutent in the etching solution, prolong the work-ing life of etching solution, reduce the usage quantity of new etching solution, and simple in structure, easy to implement.
The utility model for the technical scheme that solves its technical problem and adopt is:
A kind of decontamination cycle reusing appts of printed circuit board (PCB) etching solution, etching bath has etching solution import and etching solution outlet, be provided with adsorption tank, filter, holding tank and supply case, the etching solution outlet of described etching bath connects described adsorption tank by pipeline, pipeline between described etching bath and the described adsorption tank is provided with transferpump, described adsorption tank is divided into two sections of front and back and is respectively the leading portion adsorption tank and the back segment adsorption tank, be provided with some horizontal oil suction swab sticks in the described leading portion adsorption tank, be provided with some longitudinally activated carbon columns in the described back segment adsorption tank, described back segment adsorption tank connects described filter by pipeline, described filter connects described holding tank by pipeline, described supply case connects described holding tank by pipeline, and the pipeline between described supply case and the described holding tank is provided with the supply volume pump, and described holding tank connects the etching solution import of described etching bath by pipeline.
The beneficial effects of the utility model are: the decontamination cycle reusing appts of printed circuit board (PCB) etching solution of the present utility model is provided with adsorption tank, filter, holding tank and supply case, used etching solution is under the effect of transferpump in the etching bath, through adsorption tank organic impurities was adsorbed before this, then enter further to filter in the filter and filter out impurities, enter again in the holding tank, because amount can be few after etching solution used, therefore carry out supply by the supply case, through purification and dosage after clean etching solution more again holding tank enter in the etching bath, realize purification and the recycling of etching solution with this, therefore can effectively prolong the duration of service of etching solution, reduce the quantity discharged of spent etching solution and the add-on that reduces new etching solution, have better economic benefit and environmental benefit.
