Abstract

The utility model relates to an energy-saving electrolytic zinc negative plate, comprising an aluminum beam, an aluminum plate and a conducting clamp which are combined. The utility model is characterized in that the lower part and the upper end of the aluminum beam are fixedly connected with the aluminum plate with a plurality of holes, a molten zone is arranged between the upper part of the aluminum beam and the top end of the aluminum plate, and an aluminum rivet for strengthening and fixing is added between the original conducting clamp of one side of the aluminum beam and the welding seam of the aluminum beam and bolts fixing the conducting clamp and the aluminum beam. The utility model has the advantages of reasonable structure, good performance, high electrolytic effect, long service life and low manufacturing cost, being the ideal renewing product of the present electrolytic zinc negative plate.

Description

Energy-saving electrolytic zinc negative plate

The utility model belongs to electrometallurgy technical field, particularly cathode plate for electrolyzing zinc.

At present, the formation of the negative plate that China's electrolytic zinc plant uses combines aluminium beam and aluminium sheet by welding, and conductive clip also is fixed by welding on the aluminium beam, adds bolting again and connects.Owing in welding process, generate a large amount of fine and close oxide film (Al between the aluminium beam of casting and the rolling aluminium sheet ₂O ₃), produce pore, make tissue looseness, resistance increases, and the influence electricity is imitated and work-ing life.In addition, cause the aluminium sheet wave transformation, make stripping zinc difficulty because welding is shunk.This negative plate also has weak points such as manufacturing cost height.

The purpose of this utility model provides a kind of electricity that can improve and imitates, and prolongs the work-ing life of negative plate, reduces the energy-saving electrolytic zinc negative plate of manufacturing cost.

Negative plate described in the utility model is combined by aluminium beam 1, aluminium sheet 2 and conductive clip 3, it is characterized in that: the bottom of aluminium beam 1 has the aluminium sheet 2 of some eyelets 8 to fixedly connected with its upper end, has one to dissolve district 7 between the top of the top of aluminium beam 1 and aluminium sheet 2; The weld seam 4 of original conductive clip 3 of aluminium beam 1 one sides and aluminium beam 1 and fix and increase by one between their bolt 6 and be used to strengthen fixed aluminium rivet 5.

Fig. 1 is the utility model front view.Fig. 2 is Figure 1A-A line sectional view.Fig. 3 is Figure 1B-B line sectional view.

The utility model is further described by enforcement below in conjunction with accompanying drawing.

Fig. 1 has not only clearly shown one-piece construction of the present utility model, gives the aluminium rivet 5 that increases newly on the conductive clip 3 simultaneously, and its position is between weld seam 4 and bolt 6.

Aluminium beam 1 and aluminium sheet 2 among Fig. 2 are combined as a whole by melting district 7, and this melt and dissolved district 7 is positioned at the 1/3-2/3 place under aluminium beam 1 upper limb.5-7 the eyelet 8 that aluminium sheet 2 upper ends have, the medullary ray of this eyelet 8 to the distance of aluminium beam 1 lower rim be aluminium beam 1 width 1/5.

The aluminium rivet 5 that increases newly among Fig. 35 expression conductive clip 3, this figure has clearly illustrated that the reinforcement fixed connection structure of aluminium rivet 5.

The utility model has the advantages that rational in infrastructurely, functional, both can improve electricity effect and service life, and can reduce manufacturing cost. Because this minus plate No oxided film and the distortion of no wave, so not only resistance is little, electric conductivity is significantly improved than the welded cathode plate of existing domestic use. Can improve electricity effect about 3% through preliminary examination, reduce by 3 tank voltages, the aluminium sheet unit consumption also is reduced to 0.4 slice/ton by welded 0.55 slice/ton, so improved the service life of minus plate. Be the desirable regeneration product of existing electrolytic zinc anode plate really.
