Abstract
The invention discloses an improved coarse filter device for producing an electrolytic copper foil. The coarse filter device comprises a tank body and a filter assembly located in the tank body; the tank body is provided with a liquid inlet and a liquid outlet and is separated into an upper part and a lower part through a separating plate, that is to say, the upper part is a liquid outlet cavity, and the lower part is a liquid supply cavity; the filter assembly is composed of a plurality of cylindrical filters which are fixed side by side on the separating plate, the upper end of each filter is provided with an opening, the lower end of each filter is provided with a blind end, and each filter comprises three layers which are an outer filter screen, a filter bag, an inner filter screen from outside to inside. Because the inner filter screen and the outer filter screen are both made of hard materials, the soft filter bag is placed between the inner filter screen and the outer filter screen, so that the filter screens play a role in supporting the soft filter bag, so as to prevent the soft filter bag from deforming during a filtering process and to prevent the bag from destroying. The coarse filter device especially can resist press, resists electrolyte shock, allows the liquid supply amount to be increased, ensures that a filtered electrolyte is qualified, and can significantly improve the production efficiency.
Description
Technical field
The present invention relates to production high accuracy electrolysis Copper Foil technical field, relate in particular to a kind of coarse filtration device of improved production electrolytic copper foil.
Background technology
In electrolytic copper foil production technology, electrolyte preparation is the first operation that electrolytic copper foil is produced, and is mainly that copper junk is dissolved into copper-bath, and through a series of filtration, purifications, prepares the electrolyte that composition is qualified, degree of purity is very high.The quality of electrolyte quality, directly affects the quality of Copper Foil product quality, not only affects the inherent quality of Copper Foil, also affects the presentation quality of Copper Foil.In the molten copper process of strict control, copper junk used, seeming of filtration system is most important.
What conventional active carbon filter adopted is inner pressed filter type, in filtering cloth bag, pack active carbon into, electrolytic solution to be filtered directly pumps into cloth bag (nonwoven material through high-pressure pump, socks shape), through active carbon filtering layer, filter again, filtering accuracy requires as 1um, because cloth bag is, increase along with active carbon addition, under the lasting liquid supply pressure of high-pressure pump, service time, the slightly long filter bag that is easy to blocked, when arriving certain pressure, there is broken bag perforation phenomenon, at this moment active carbon can pass filter bag, cause electrolyte deteriorated, quantity scrapped rolls up, need to shut down and carry out large-area treatment, a large amount of manpower and materials have been wasted.
Now being transformed into external-compression type adds screen pack mode and filters, active carbon packs filter cavity into, do not pack cloth bag into, the solution pumping into during work enters cloth bag through active carbon filtering layer from the outside of cloth bag, and add a cover fixedly filter bag of rotary pressure plate at upper cover, and effectively prevent the harm of filter bag broken bag, guaranteed the continual and steady operation of system, improve product quality, reduced percent defective.
Summary of the invention
The coarse filtration device that the object of this invention is to provide a kind of improved production electrolytic copper foil, this device has and does not block broken bag, good filtration effect, feed flow is stable, the advantage that maintenance cost is low.
The object of the invention is to be achieved through the following technical solutions, the filter assembly that this active carbon filtering device comprises tank body and is positioned at tank body, described tank body is cylindrical shape, described tank body is provided with inlet and liquid outlet, described tank body is divided into by dividing plate, lower two parts, be top for going out sap cavity, bottom for for sap cavity, described filter assembly is by a plurality of upper end open that are fixed on side by side on dividing plate, lower end is that the columnar filter of cecum forms, described filter comprises three layers, be followed successively by from outside to inside outer screen pack, filter bag, filtering net.
Described outer screen pack and filtering net be cylindrical wall be provided with numerous filtering holes thoroughly Steel material make.
Described filter bag is the software cloth bag of nanofiltration.
The long 98cm of described filter bag, diameter is 20cm.
During work, electrolyte enters supplying in sap cavity of tank body by inlet, by the filter filtration being positioned at for sap cavity, enter out sap cavity again, during filtration, under the pressure of the pump housing, electrolyte enters out sap cavity by outer screen pack, filter bag, the filtering net three layer filtration of each filter, then by liquid outlet, flows out.
Beneficial effect of the present invention: because inside and outside screen pack is that hard material is made, software filter bag is sandwiched in wherein, software filter bag is played a supporting role, prevent that software filter bag from deforming, ruining bag in filter process.Energy resistance to compression especially, the impact of anti-electrolyte, liquid supply rate increases, and guarantees to filter out qualified electrolyte, can significantly improve production efficiency.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, describe embodiments of the invention in detail

Fig. 2 is the cutaway view of filter
In figure: 1, tank body 2, filter assembly 3, inlet 4, liquid outlet 5, dividing plate 6, go out sap cavity 7, for sap cavity 8, filter 9, outer screen pack 10, filter bag 11, filtering net
The specific embodiment
As Fig. 1, shown in Fig. 2, the filter assembly 2 that this coarse filtration device comprises tank body 1 and is positioned at tank body 1, tank body 1 is cylindrical shape, tank body 1 is provided with inlet 3 and liquid outlet 4, tank body 1 is divided into by dividing plate 5, lower two parts, be top for going out sap cavity 6, bottom for for sap cavity 7, filter assembly 2 is by a plurality of upper end open that are fixed on side by side on dividing plate 5, lower end is that the columnar filter bag 8 of cecum forms, the long 98cm of filter bag 8, diameter is 20cm, filter 8 comprises three layers, be followed successively by from outside to inside outer screen pack 9, filter bag 10, filtering net 11, outer screen pack 9 and filtering net 11 be cylindrical wall be provided with numerous filtering holes thoroughly Steel material make, filter bag is the software cloth bag with numerous filtering holes.
During work, electrolyte enters supplying in sap cavity 7 of tank body 1 by inlet 3, by filter 8 filtrations that are positioned at for sap cavity 7, enter out sap cavity 6 again, during filtration, under the pressure of the pump housing, electrolyte enters out sap cavity 6 by outer screen pack 9, filter bag 10, filtering net 11 three layer filtrations of each filter 8, then by liquid outlet 4, flows out.
