Description
Technical Field
The invention belongs to the technical field of electrochemistry, and particularly relates to a composite type energy-saving electrolytic electrodeposition conductive connecting device.
Background
In the electrolytic electrodeposition production process of nonferrous metal smelting, the conductive connection mode of electrolytic electrodeposition has various structural forms, but the electrolytic electrodeposition is mainly classified by the connection mode of lap joint and clamping, and the lap joint is that the conductive contact realizes the conductive connection through the mutual convenient lap joint mode; also, the conductive contacts are clamped tightly, and although the conductive connection modes of the lap joint and the clamping are different and have different advantages, the conductive connection modes of the lap joint and the clamping are finally developed in the direction of large-scale and mechanical automation, namely the conductive mode of the lap joint with more convenience and advantages is changed to the direction of gradually replacing the conductive mode of the clamping.
For the electrolytic and electro-deposition conductive connection, the main factor influencing the conductive quality is resistance, the contact resistance generally comprises three parts, one is the contraction resistance on one side of the contact element, the other is the surface resistance between the contact surfaces, the third is the contraction resistance on the other side of the contact element, and the three parts form a series resistance relation on the circuit, namely RGeneral assembly=R1+R2（R1To shrink the resistance, R2Surface resistance). The physical nature of the contact resistance was not correctly explained by the founder holm (r. holm) of the electrical contact discipline until the beginning of the last century, who noted that any metal surface that was very smooth to the naked eye was actually rough and uneven, and when two metal surfaces were in contact with each other, only a few protruding points (facets) made true contacts, where only a small portion of the metal or metalloid contacted spots could conduct electricity. As the current path through the small conductive spots increases, the effective conductive cross section decreases and the resistance increases accordingly, and this additional resistance due to the contraction of the current lines, called the contraction resistance, is a component constituting the contact resistance. Secondly, if the film between the actual contact surfaces is conductive, due to the presence of the film on the metal surface, there will be some hindrance to the passage of current through the film, and there is another additional resistance, called the film resistance (sheet resistance), which is another component constituting the contact resistance. Also, the film resistance (surface resistance) is due to the poor conductive coating of substances, and the coating of the contact surface may be metal chlorides, sulfides, etc., which are generated by chemical interaction of the electrical contact material with the surrounding medium such as air, corrosive gases and substances.
At present, two common lapping conductive connection modes are provided, one mode is that a cathode conductive head and an anode conductive head are directly connected in a surface contact or simple line contact mode through a simple plane or round surface middle conductive bar to realize electrolytic electrodeposition conductive connection; the other is that the cathode and anode conductive heads are connected in an electrolytic electrodeposition conductive manner in a surface contact or simple line contact manner through middle conductive bars in different structural forms. The conductive connection modes are all in surface contact or simple line contact connection, and the problems of uneven conduction, overcurrent and the like are easily caused due to the difference of conductive contact surfaces, so that the conductive contact points generate heat, the production load is limited, the product quality is influenced, and even the polar plate is damaged. The existing solution is poor in effects of only enhancing management, properly reducing production load and the like, and reducing the electric shock temperature difference of the whole conductive bar by flushing, updating and replacing a contact surface or by a forced circulating water cooling mode. For the anode lap joint contact point, the size and the form of the lap joint surface can be properly adjusted through the characteristics that the anode is relatively heavy and the pressure intensity of the contact surface can be increased, although the conductive contact problem can be solved to a certain extent, the phenomena of influencing the production load, generating heat unevenly due to conduction and the like are the problems of the anode lap joint contact surface, and the current distribution is uneven easily caused due to the fact that the cathode plate is relatively light in the initial electrolysis stage, the pressure intensity of the lap joint contact surface is small, the conduction is unstable and even, and therefore local heating is caused, and the load of the current is limited. Therefore, it is necessary to develop a composite type energy-saving electrowinning conductive coupling device capable of solving the above problems.
