Description
Technical field
The utility model relates to a kind of cold rolled strip electrolytic cleaning electrode.
Background technology
Belt steel surface after cold rolling is mainly ROLLING OIL, iron powder etc. with a large amount of residues, and the existence of these residues brings disadvantageous effect to subsequent handling, so must clean the belt steel surface after cold rolling.Cleaning generally is that the alkali cleaning, the alkali that comprise are scrubbed, electrolytic cleaning, water are scrubbed, the combined multi-stage of water rinse etc. is strengthened and cleaned.In order to improve surface cleanness of cold rolled strip steel, the modern cold strip cleaning all can add the electrolytic cleaning technology mostly, to can effectively remove be difficult to remove through other cleaning ways, still remain in the residual dirt of the small pit of belt steel surface, thereby obtain high-quality cold rolled strip.
The electrolytic cleaning technology, by the electrolytic rectifier output DC, produce inductance by electrolytic solution between band steel and the electrode, electrolysis and the band steel as anode or negative electrode, carry out electrode reaction and precipitated oxygen or hydrogen on its surface, rely on just the mechanical stirring of bubbing on the electrode and the effect of peeling off to remove the dirt that remains in small pit.
At present production practice are found, a lot of steel mills cold rolling workshop electrolytic cleaning is with the extremely easy corrosion of electrode, pole plate is shorter general work-ing life, and also not too clear for the reason of pole plate corrosion both at home and abroad, although proposed to improve the measure of pole plate corrosion, as strengthen equipment ground, regularly change polarity of electrode and realize that equivalent plates, changes electrode materials etc. mutually, but also can only partly prolong pole plate duration of service, still can not thoroughly change shorter present situation of general life-span of pole plate.The way of present most of steel mill is after the pole plate corrosion failure can not use, the pole plate that more renews.Because pole plate is connected with the mode of power pins by welding, power pins is fixed in the groove simultaneously, so the replacing of pole plate operation all is to carry out in groove.Because narrow space in the groove, severe operational environment is unfavorable for and changes operating; Simultaneously welding easily damages the line with rubber in the groove accidentally, thereby the cell body life-span is reduced.
In addition, power pins generally adopts the L-type steel in the design of electrolysis cells in the past, that single-point contacts with the welding of angle steel, easily cause the loose contact of some pole plate and power pins in the use procedure owing to corrosion, electric current can not be transmitted to pole plate well, thereby electrolytic effect can not occur, correspondingly cause the average current density on the pole plate bigger than normal, affect the distribution of electric current.
Summary of the invention
The purpose of this utility model provides a kind of cold rolled strip electrolytic cleaning electrode, and this device can be realized the easy removal of pole plate, is convenient to replacing and the maintenance of pole plate.
For achieving the above object, technical solution adopted in the utility model is a kind of cold rolled strip electrolytic cleaning electrode, it is characterized in that: it comprises fixed power source pin, mobile electric power pin, pole plate and copper bar, copper bar becomes U-shaped and passes the fixed power source pin, the fixed power source pin links to each other with the top of mobile electric power pin by anti-corrosion bolt, and the lower end of mobile electric power pin is welded on the pole plate.
Described fixed power source pin is C shaped steel, and copper bar passes C shaped steel, and the inboard of C shaped steel upper wall contacts with copper bar; Described mobile electric power pin is the right angle Z-shape steel, and the upper wall of right angle Z-shape steel is by on the anti-corrosion mesospore that is bolted to C shaped steel, and the mesospore of right angle Z-shape steel contacts with the inboard of C shaped steel lower wall, and the lower end of right angle Z-shape steel is welded on the pole plate.
The lower end of described mobile electric power pin is provided with a plurality of tie points for welding mutually with pole plate, and a plurality of tie points are welded on the pole plate uniformly.
Described copper bar skin is provided with line with rubber, and copper bar and fixed power source pin touching position do not have line with rubber (conductive contact between the two).
Described pole plate is in a row formed side by side by many battery lead plates, a plurality of tie points of mobile electric power pin lower end uniformly with every electrode plate welding.
The beneficial effects of the utility model are:
(1) fixed power source pin and mobile electric power pin are with bolts, like this when needs are changed pole plate, mobile electric power pin under can easy removal, outside groove, corrode the dismounting of pole plate and the welding job of new pole plate, be convenient to replacing and the maintenance of pole plate, avoid simultaneously cell body is damaged; The groove external welding can also guarantee the quality of welding can guarantee that the absolute altitude of each root battery lead plate is consistent, is conducive to like this being evenly distributed of electric current, guarantees current efficiency and cleaning quality;
L-type steel before (2) C shaped steel replaces is as the fixed power source pin, and Z-shape steel is done the activity power pins, so that the fixed power source pin has good the contact with the mobile electric power pin, realizes the conduction of electric current; Simultaneously owing to there being the circulation of electrolytic solution in the electrolyzer, so there are violent vibrations in cell body inside, this structure so that the fixed power source pin be connected connection with the mobile electric power pin very stable, satisfy the requirement on the intensity;
(3) the mobile electric power pin is drawn the multiple spot feeler and is realized being connected with battery lead plate that multiple spot connects, and is conducive to conduction of current and arrives pole plate, is conducive to the distribution of rectifier received current.
