Description
Technical field
The relevant a kind of cleaning electrode of the utility model refers to the cold rolled strip electrolytic cleaning electrode that a kind of insulativity is good especially.
Background technology
Belt steel surface after cold rolling is with a large amount of residues, be mainly ROLLING OIL, iron powder and loose impurity etc., the existence of these residues brings disadvantageous effect to subsequent handling, and cause the final finished quality deteriorated, must clean the belt steel surface after cold rolling in the production processes such as silicon steel and galvanized sheet.At present cleaning be generally comparatively complicated alkali cleaning (chemistry)+alkali and scrub (physics+chemistry)+electrolytic cleaning+water and scrub+combined multi-stage of water rinse strengthens and cleans.After cold rolled strip process alkali hydro-peening and alkali were scrubbed, the dirt major part on surface was cleaned removal, but still was difficult to clean at the residual dirt of the small pit of belt steel surface, and electrolytic cleaning can effectively be removed the dirt of this part pit.
The electrolytic cleaning technology, by the electrolytic rectifier output DC, produce inductance by electrolytic solution between band steel and the electrode, electrode 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.As shown in Figure 1, be with at present the steel electrolytic cleaning, deflector roll 70 drive the band steel by electrolytic cleaning tank 71 with sinking roller 75, are provided with two arrays of electrodes in the rinse bath, and every group of electrode comprises electric pole plate 72 and lower electrode plate 73, is provided with direct supply 74 between this two arrays of electrodes.
And present electrolytic cleaning technology on the one hand, improves rectifier current output, can increase the generating capacity of gas on the electrode, then can improve cleaning performance; Reduce electrode and with the dividing potential drop of solution between the steel, can reduce the output rating of power supply, improve the efficient of power supply, and reduce pole plate and can reduce its dividing potential drop with the distance between the steel, if partial pressure of liquor reduces, then can improve electric current and increase cleaning performance.On the other hand, because the band steel is in operational process, in electrolytic cleaning section lose and open suddenly, perhaps be with steel severe edge wave or middle wave to occur, perhaps be with steel vibrations in service, cause the band steel contact with pole plate and short circuit occurs to overlap, under the high electric current in part, be with steel moment ablated, therefore when design, require electrode with can not be too near with the distance between the steel, be with steel and electrolysis contact short circuit ablated otherwise cause easily.
Seal is set at electrode and band between the steel, can be when reducing pole plate as far as possible and being with the steel spacing, prevent from being with steel and electrode contact short circuit and ablate.Existing electrode adopts angle steel or grid class arranged in form more, and kind electrode potential can also further improve.
The utility model content
In view of this, main purpose of the present utility model is to provide a kind of cold rolled strip electrolytic cleaning electrode of simple in structure and good insulating.
For achieving the above object, the utility model provides a kind of cold rolled strip electrolytic cleaning electrode, it comprises a plurality of semicircular electrode plates, is located at the seal of this semicircular electrode plate below, is located at the copper bar of this semicircular electrode plate top and the electrode supply pin that is electrically connected with this copper bar, a plurality of these semicircular electrode plates are arranged in parallel and arrange one group of electrode of formation, link to each other with the described electrode supply pin of both sides respectively by welding process; Described copper bar skin is provided with line with rubber and becomes U-shaped to pass this electrode supply pin, and conduction contacts with this electrode supply pin.
Described electrode supply pin is made by the L carbon steel, and is fixed on the described copper bar.
Described semicircular electrode plate is the carbon steel electrode plate.
Described seal comprises the welding steel of perforate, the bolt that pinblock is anti-corrosion and insulcrete, this welding steel welding also is fixed in position between the adjacent described semicircular electrode plate of two rows, have angle between this insulcrete and the described semicircular electrode plate, this insulcrete is bolted on this welding steel by this.
Angle between described insulcrete and the described semicircular electrode plate is acute angle or obtuse angle.
Described insulcrete is the epoxy resins insulation plate.
Described semicircular electrode plate working face is streamlined.
The utility model is arranging fixing insulcrete with the steel working face, the little steel plate of welding between two-plate, and insulcrete is fixed on above the welding steel by cross screw bolt, and bolt is counterbore; Insulcrete and pole plate are non-90 ° of layouts.The insulcrete beneficial effect is set is: when causing when contacting with steel and charged electrode owing to the reason such as losing; owing to arrange insulcrete at band steel working face; this belt transect steel can contact with insulcrete first; phenomenon so just can not be short-circuited; because insulcrete adopts the soft material of quality, belt steel surface can be by scratch yet, simultaneously insulcrete to electric current at pole plate and little with the flow effect between the steel; insulcrete and pole plate are non-90 ° of layouts in addition, can indirectly improve the protection domain of insulcrete.
The utility model cold rolled strip electrolytic cleaning electrode adopts semicircle pole plate to arrange, can improve current efficiency, improves cleaning performance, and the battery lead plate working face arranges seal, can prevent in the groove that the band steel is short-circuited losing etc. in the situation to contact with charging electrode.

Embodiment
For ease of structure of the present utility model and the effect that reaches are had further understanding, the existing preferred embodiment that develops simultaneously by reference to the accompanying drawings is described in detail as follows.
Such as Fig. 2 and shown in Figure 4, cold rolled strip electrolytic cleaning electrode of the present utility model, it comprises a plurality of semicircular electrode plates 1, is located at the seal 2 of semicircular electrode plate 1 below, is located at the copper bar 4 of semicircular electrode plate 1 top and the electrode supply pin 3 that is electrically connected with copper bar 4.A plurality of semicircular electrode plates 1 are arranged in parallel and arrange form one group of electrode, and the mode by welding is the L power pins with the electrode supply pin 3(of both sides respectively) link to each other; Copper bar 4 skins are provided with line with rubber and become U-shaped to pass electrode supply pin 3, and the conduction that contacts with electrode supply pin 3 simultaneously can the fixed support battery lead plate; Electrode supply pin 3 is made by the L carbon steel, is fixed on the copper bar 4.Such as Fig. 3 and shown in Figure 5, seal 2 in the utility model comprises the welding steel 20 of perforate, pinblock is anti-corrosion bolt 21 and insulcrete 22, welding steel 20 is welded between adjacent two row's semicircular electrode plates the position and makes and himself fix, insulcrete 22 is to be fixed on the welding steel 5 by anti-corrosion bolt 21 with semicircular electrode plate 1 certain angle, the joint bolt counterbore, angle between insulcrete 22 and the semicircular electrode plate 1 is acute angle or obtuse angle, be non-90 °, the insulcrete 22 in the utility model is the epoxy resins insulation plate.
