technical field

The utility model relates to the field of metallurgy and chemical industry, in particular to a fixed electrolytic pole plate.

Background technique

An important process of zinc hydrometallurgy is zinc electrolysis, and the main devices of zinc electrolysis are: electrolytic cell, cathode plate, and anode plate. At present, the general method of installing electrolytic plates is as follows: the cathode plate and the anode plate are alternately installed in the same electrolytic cell, and the conductive clip of the negative plate is clamped together with the conductive head of the anode plate of the adjacent electrolytic cell, so as to realize the The plates are electrically conductive, that is, the electrolytic cells are connected in series with the adjacent electrolytic cells, and the anode plates in each electrolytic cell are connected in parallel. In order to improve the current efficiency and reduce energy consumption, the pole distance of the same name in the same electrolytic cell is generally set to 67~68mm, while the pole distance of the same name is 33.5~34mm. Due to the certain thickness of the electrolytic plate and the conductive rod of the plate, the different name The gap between the pole plates is less than 25mm, and the gap between the conductive rods of different name plates is less than 15mm. In production practice, how to control the uniformity of the spacing between the electrolytic plates in the same electrolytic tank has become one of the key issues in zinc electrowinning.

The current general method is: directly place the anode plate and the cathode plate frame on the hard PVC insulating plate through the conductive rod on the plate, maintain the relative stability of the electrolysis plate through their own gravity, and keep the electrolysis electrode through the visual inspection of the workers. The plate spacing is relatively uniform. This method of placing the electrolytic plate, because there is no plate fixing device, easily causes uneven spacing between the electrolytic plates, the cathode plate and the anode plate are in contact, especially the conductive rod of the cathode plate is in contact with the conductive rod of the anode plate, This leads to a short circuit between the electrolytic plates, the zinc deposited in the cathode plate dissolves back, the current efficiency is low, and the power consumption increases significantly, which in turn affects the operating costs of the enterprise.

Contents of the invention

Aiming at the defects of uneven spacing between the plates and easy contact between the cathode plate and the anode plate existing in the existing fixed electrolysis plate, a fixed electrolysis plate is provided, and its technical scheme is as follows:

A fixed electrolytic plate, including an insulating plate, an anode plate conductive rod and a negative plate conductive rod, characterized in that: an electrolytic plate holder is arranged on the insulating plate, and the anode plate conductive rod is placed in the fixing groove of the electrode plate holder , one end of the cathode plate conductive rod is placed on the plate holder.

Both sides of the electrolytic plate holder are concave-convex tooth-shaped.

One end of the conductive rod of the anode plate is provided with a conductive head, and one end of the conductive rod of the cathode plate is provided with a conductive clip, and the conductive head of the conductive rod of the anode plate and the conductive clip of the conductive rod of the cathode plate are connected to each other.

The plate holder is directly laid on the insulating plate.

The insulating board is a rigid PVC insulating board.

The utility model has the advantages that: by adding a simple pole plate holder on the insulating plate, not only the effect of fixing the electrolysis pole plate can be achieved, but also the distance between the electrolysis pole plates can be stabilized, effectively preventing the cathode plate and the anode plate from colliding. Contact to avoid short circuit between electrolytic plates.
