Description

A kind of Novel cathode plate conductive head

Technical field

The utility model relates to a kind of conductive head, is specifically related to a kind of Novel cathode plate conductive head.

Background technology

In Zinc Hydrometallurgy Process, the use of negative plate is absolutely necessary, using pb-ag alloy plate as anode, extruded aluminum plate as negative electrode, the alternate electrolyzer that is placed in is as electrolysis electrode in turn.

The conductive head of current domestic zinc metallurgy splicing processes has: copperhead is fixed on cathode collector bar by (1), uses conductive head direct-electrifying to (as Fig. 1) on negative electrode; (2) copper sheet is cast in aluminium block, be then welded to (as Fig. 2) on cathode bar; (3) conducting copper is made equidistant recessed dovetail groove, conductive head is made inverted trapezoidal, mutual embedding tight (as Fig. 3); (4) conducting copper is done in echelon, conductive head makes the shape of a saddle, conductive head and conducting copper is engaged up and down conduct electricity (as Fig. 4).

From conductivity, above several conductive head performance is all similar; From processing mode, (1), (3), (4) three kinds of processing mode more complicated are difficult to processing, (2) although plant processing mode simply, but the cathode conducting head found that there is in process of production scalds one's hand, cathode conducting head one scalds one's hand and will make copper sheet surface blackening (oxidation), solution of zinc sulfate crystallization on copper bar increases conductive head resistance, thus occurs " saturating sour plate " (redissolution); Cause above reason mainly conductive head and copper bar contact area little, making resistance increase by generating heat during big current.

Utility model content

The purpose of this utility model is to provide a kind of increase conductive contact area, reduces the Novel cathode plate conductive head of resistance.

The technical solution of the utility model is achieved in that a kind of Novel cathode plate conductive head, comprises aluminium block and T-shaped copper bar, and described aluminium block is welded on T-shaped copper bar; Described T-shaped copper bar is made up of T-shaped copper bar head and T-shaped copper bar bar, and this T-shaped copper bar head is vertically connected on T-shaped copper bar bar.

Further, the width L1 of described T-shaped copper bar head is 15 ~ 25mm, length L2 is 35 ~ 45mm.

Further, the thickness L3 of described T-shaped copper bar bar is 6 ~ 10mm.

Further, the length L4 that described T-shaped copper bar bar exceeds described aluminium block away from one end of described T-shaped copper bar head is 4 ~ 10mm.

Further, the thickness L5 of described T-shaped copper bar bar 4 ~ 6mm larger than the thickness L6 of described aluminium block.

The beneficial effects of the utility model are: the structure of this negative plate conductive head is simple, and less investment, the cost of manufacture is low, durable, energy consumption is low, is a kind of device that greatly can reduce zinc electrolysis production cost.

Accompanying drawing explanation

In order to be illustrated more clearly in the technical scheme of the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only one of them embodiment of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Fig. 1-4 is the structural representation of existing conductive head;

The structural representation of Fig. 5 the utility model embodiment front view;

Fig. 6 is the structural representation of A-A line in Fig. 5.

In figure, 1-aluminium block, 2-T shape copper bar, 21-T shape copper bar head, 22-T shape copper bar bar.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only one of them embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.

As seen in figs. 5-6, a kind of Novel cathode plate conductive head, comprises aluminium block 1 and T-shaped copper bar 2, and aluminium block 1 is welded on T-shaped copper bar 2; T-shaped copper bar 2 is made up of T-shaped copper bar head 21 and T-shaped copper bar bar 22, and this T-shaped copper bar head 21 is vertically connected on T-shaped copper bar bar 22.

Wherein, the width L1 of T-shaped copper bar head 21 is 15 ~ 25mm, length L2 is 35 ~ 45mm.

The thickness L3 of T-shaped copper bar bar 22 is 6 ~ 10mm.

Wherein, the length L4 that T-shaped copper bar bar 22 exceeds aluminium block 1 away from one end of described T-shaped copper bar head 21 is 4 ~ 10mm.

The thickness L5 4 ~ 6mm larger than the thickness L6 of aluminium block 1 of T-shaped copper bar bar 22.Concrete, the thickness L5 of T-shaped copper bar bar 22 exceeds the part of the thickness L6 of aluminium block 1, is evenly distributed in aluminium block 1 both sides.

Adding man-hour, after being fixed by size positions by T-shaped copper bar 2, casting ladle is wrapped in aluminium block 1, and exposes conducting position (i.e. 3 protruding parts of T-shaped copper bar 2), to obtain final product.

The utility model is through test, and technique effect is as follows: a, cathode and anode touch voltage reduce to 6 ~ 11mV; Busbar and anode and cathode conductive head temperature 35 ~ 45 DEG C between b, cathode and anode; C, zinc electrolysis current efficiency can reach 94 ~ 96%.By increasing negative plate conductive head conductive area, reducing heat energy loss, reducing bath voltage, reduce electrolysis direct current electricity unit consumption.

It is 6.5 ten thousand tons/year for Yunnan mining and metallurgy company zinc Production design ability, after use cathode conducting head of the present utility model, little discovery conductive head is hot, copper aluminum portions does not find the vestige be separated yet, unit dc consumption, also at 2900 KWhs/ton of zinc metal sheets, calculates by every groove 62 pieces of negative plates, can voluminous 11 ㎏ electrolytic zinc plates compared with conventional conductive head negative plate, thus greatly reduce the running cost of electrolysis, improve zinc electrolysis efficiency.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
