Abstract

The utility model relates to a current short circuit device for electrolysis and electrowinning process. The current short-circuit device for electrolysis and electrowinning process is composed of a conductive plate, a short-connected copper busbar and an insulating plate. The conductive plate is placed on the edge of the electrolytic tank. There is an insulating board, and the other side of the insulating board is equipped with a short-circuit copper busbar. The utility model can carry out the short-circuit operation of a single electrolyzer, and can also perform short-circuit operation on multiple electrolyzers at the same time according to the actual production situation, and the operation flexibility is large; for the electrolyzer with relatively small current intensity, it can reduce labor intensity and reduce the The unsafe factor of the operation on the groove surface can also save the expensive short-circuit switch.

Description

Electrolysis and electrodeposition process short circuit current device

Technical field

The utility model belongs to electrolytic non-ferrous metal and electrodeposition technical field, relates generally to electrolysis and electrodeposition processes such as copper, nickel, particularly electrolysis and electrodeposition process short circuit current device.

Background technology

The electrolysis of copper, nickel and electrolytic deposition process place groove all based on electrochemical principle with cathode and anode in the non-ferrous metal, and electrochemical reaction takes place on electrode in the energising back, has metals ion constantly to separate out on the negative electrode.When the some cycles of working, need electrolyzer short circuit outage, take out corresponding negative electrode or anode or cleaning groove electrolyte inside, promptly be called the dress electrolyzer.General power-down mode has two kinds, and a kind of is horizontal copper rod outage, manual operation, and it is bigger to work, and it is unfavorable to safety on groove face, to work; Another kind of is to adopt the remote control short circuiting switch, but both the metering house handles, but also on-site manual operation.Domestic general midget plant actuating current intensity is little, the artificial horizontal bar short circuit outage of available single groove; And large and medium-sized factory adopts big pole plate, big electrolyzer factory; Actuating current intensity is big, should adopt remote control short circuiting switch outage, to reduce labor intensity and to protect the insulating pad of groove face; Establish a short circuiting switch for general two groups; Relatively the former is lower for the groove operating rate, and invests higherly, and flexibility of operation is little.

Summary of the invention

The purpose of the utility model is; A kind of device of short circuit current method of electrolyzer is provided, and is not under the excessive situation through being directed to strength of current, with organizing the short circuit mode that electrolyzer is a unit more; Can carry out the short circuit operation of single electrolyzer; Also can carry out the short circuit operation to a plurality of electrolyzers simultaneously according to the practical situation of producing, flexibility of operation is big; For strength of current electrolyzer less than normal, can reduce labor intensity, be reduced in the unsafe factor of operating on the groove face, also can save expensive short circuiting switch.

For realizing above-mentioned purpose; The utility model is taked following technical scheme, and electrolysis and electrodeposition process short circuit current device are made up of conducting plates, short circuit copper bus-bar and insulcrete; The conduction grillage is on the electrolyzer edge; One end of conducting plates stretches out outside electrolyzer, and the external part two sides are equipped with insulcrete, and the another side of insulcrete all is equipped with the short circuit copper bus-bar.

Conducting plates one end of electrolyzer is prolonged, be connected, during ordinary production, between short circuit copper bus-bar and conducting plates, embed insulcrete, avoid contacting of conducting plates and short circuit copper bus-bar with two short circuit copper bus-bars; As need carry out short circuit when operation to certain electrolyzer, and only need two insulcretes are taken out and can realize short circuit, use clamp between two short circuit busbars.

The utility model is broken common employing a small amount of electrolyzer is merged in groups; With the group is the electrolyzer short-circuit mode of unit; Thereby make that the quantity of every group of electrolyzer is no longer limited to, electrolyzer is arranged compact, and floor space is little; And can save expensive short circuiting switch, for manufacturing enterprise practices thrift certain investment.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described further; Referring to Fig. 1 to Fig. 3, electrolysis and electrodeposition process short circuit current device are made up of conducting plates 1, short circuit copper bus-bar 2 and insulcrete 3; 1 of conducting plates is on the electrolyzer edge; One end of conducting plates 1 stretches out outside electrolyzer, and the external part two sides are equipped with insulcrete 3, and the another side of insulcrete 3 all is equipped with short circuit copper bus-bar 2.

In practical implementation, during electrorefining, the casting of metals that the electrolyzer inner anode is purified by need forms, and in electrowinning plant, can adopt the certain thickness alloy sheets that electrochemical dissolution can not take place.The starting sheet that negative electrode can adopt the metal sheet of corrosion resistant 3mm left and right thickness is processed or employing is identical with product metal to make, electrolyzer is provided with conducting plates 1 and is equipped with corresponding power supply system.

Embodiment: cupric electrolysis technology

In each electrolytic cell, place 41 copper starting sheets and 42 copper anode plates; Electrolytic cell is provided with conductive plate 1 and trough rim conductive plate 1 between groove; 84 electrolytic cells are one group; And establish 11 short circuit groups; Wherein 10 short circuit groups are 8 grooves; 1 short circuit group is 4 grooves; Short board is set at the group two ends and the short circuit copper bus-bar joins; Being about to electrolytic cell conductive plate one end prolongs; Be connected with two short circuit copper bus-bars; During ordinary production, between short circuit copper bus-bar 2 and electrolytic cell conductive plate 1, embed an insulation board 3, avoid contacting of conductive plate 1 and short circuit copper bus-bar 2; Like needs certain is organized electrolytic cell and carry out short circuit when operation, only need two insulation boards 3 are taken out and can realize short circuit, 2 of two short circuit copper bus-bars are used clamp, referring to Fig. 4, and are supported on the floor.
