According to the utility model, the conductive contact mode of the negative plate is improved, a traditional mode of hanging the negative plate end for conduction is replaced, a high conductivity material is compounded to the conductive part on the negative plate, the negative plate is embedded into the ear groove, and the end of the negative plate is subjected to circular arc processing, so that the conductive contact area and the embedment degree are further increased and the conductivity is improved; meantime, the surface of the negative plate is polished, so that the bonding force of electrolytic silver powder and the negative plate is reduced to facilitate the cleaning of silver powder on the surface of the negative plate, thereby avoiding the binding of the silver powder.
Description
Technical field
The utility model relates to electrolysis industry technical field, is specifically related to a kind of silver-colored electrolytic conduction device.
Background technology
In non-ferrous metal hydrometallurgy field, widespread use electrolysis process carries out Refining to metal, wherein silver-colored electrolysis is comparatively special, little Ag positive plate and silver powder doctor blade device have limited size and the thickness of negative plate, in addition in current common silver-colored electrolyzer, negative electrode adopts vertical hanging formula to contact with bus bar, thereby make negative plate be difficult to accomplish contact with the big area of cell side busbar, contact resistance is larger, poor electric conductivity, can there are problems: (1) very easily causes cell side busbar temperature to raise fast, cause electrolyzer that distortion occurs to melt, reduce electrolyzer work-ing life, (2), because heating causes part power consumption in cell side busbar heating process, cause current efficiency to reduce, (3) bad because of electrolyzer electric installation conductivity, electrolysis production process current density cannot improve, and causes electrolysis production excessive cycle, and production capacity cannot promote, (4) what negative plate was separated out during electrolysis is electrolytic silver powder, needs regularly the silver powder on anticathode plate to clear up, the too coarse cleaning difficulty in negative plate surface.
Utility model content
Technical problem to be solved in the utility model is for negative plate and cell side busbar contact area less, cause that resistance is large, poor electric conductivity, problem that electrolytic speed is low, provide a kind of negative plate and cathode busbar contact area greatly, can effectively improve a kind of silver-colored electrolytic conduction device of negative plate conductivity.
The technical scheme in the invention for solving the above technical problem is as follows:
Described cathode busbar comprises negative busbar and lower negative busbar, and described upper negative busbar and the lower negative busbar position that interlocks is provided with ear groove, and the termination of described negative plate is plugged on ear groove.
Described upper negative busbar adopts screw to be connected with lower negative busbar.
Described ear groove is circular arc.
The termination that described negative plate and ear groove are pegged graft is provided with ear, and described ear is circular-arc.
The utility model is for improving the contact area of negative plate and cell side busbar, reduce contact resistance, anticathode plate and bus bar hang the way of contact and improve, and change cathode busbar into upper and lower two square copper materials, have increased conductive contact area, thereby reduced contact resistance, reduced the thermal effect occurring on bus bar, the thawing distortion of avoiding electrolyzer to produce because cell side busbar temperature rise is too high, improves bus current, motor current density, thus accelerate electrolytic speed.For guaranteeing fully contacting and embedding of negative plate and upper Down Highway, and strengthen conductive effect, anticathode plate self structure is improved and optimizes, negative plate ear and bus ear slot part are all processed into circular-arc, guarantee its chimeric degree, avoid chimeric insufficient phenomenon square or that other shape and structures occur.Polishing is carried out on anticathode plate surface simultaneously, reduces the bonding force of electrolytic silver powder and negative plate, facilitates the silver powder cleaning of negative plate surface, avoids silver powder bonding.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A silver-colored electrolytic conduction device, comprises negative plate 1, positive plate 2, cathode busbar 3, anode conducting bus 4 as shown in Figure 1.As shown in Figure 2, cathode busbar 3 comprises negative busbar 5 and lower negative busbar 6, upper negative busbar 5 and lower negative busbar 6 middle parts are provided with ear groove 7, the termination of negative plate 1 is provided with ear 8, ear groove 7 is circular-arc with ear 8, the ear 8 of negative plate 1 embeds in ear groove 7, and upper negative busbar 5 is fixedly connected with by screw 9 with lower negative busbar 6.
The positive plate that in the utility model electrolyzer, the thick silver of employing is cast is as anode, and after energising, thick silver-colored oxidation dissolution is in electrolytic solution, and negative plate obtains electronics and separates out high purity electrolytic silver powder.Change cathode busbar into upper and lower two square copper materials, ear groove is processed into in position, intermediate portion, negative plate is embedded in bus ear groove, then use fastened by screw, increased conductive contact area, thereby reduced contact resistance, reduced the thermal effect occurring on bus bar, the thawing distortion of avoiding electrolyzer to produce because cell side busbar temperature rise is too high, improves bus current, motor current density, thus electrolytic speed improved.In order to strengthen conductive effect, it is compound that the utility model carries out copper by negative plate current-carrying part, as shown in Figure 3, Figure 4, negative plate and cell side busbar contact part and bus ear slot part is all processed into circular-arc, improves chimeric degree, strengthens its conductivity.Polished finish is carried out on the utility model anticathode plate surface, increases its surface flatness, and the high purity electrolytic silver powder of being convenient to separate out on doctor blade device anticathode plate scrapes collection, finally obtains electrolytic silver powder product.
