Benefits of technology

The invention provides an electrolytic cell cathode that can prolong the lifespan of the ionic membrane. The elastic cathode is well attached to the membrane and reduces the shaking of the membrane during use. The special elastic net prevents changes in the membrane caused by pressure fluctuations and keeps the polar spacing stable. When discharging gas, the elastic net helps to break bubbles and reduce resistance in the tank. Additionally, the elasticity and durability of the elastic net ensures uniform current density.

Problems solved by technology

However, for the existing electrolytic cell, after being used for a period of time, the position of the pole net at the cross conductive claw will be sunken when being subjected to force, which may result in an uneven net surface, thus the cell voltage is generally high.
The ionic membranes are vulnerable to damage due to the pulling of extrusion force and the unevenness of polar network.

Abstract

The invention provides an electrolytic cell cathode with zero polar spacing, which comprises a conductive column; a cathode net connected to the conductive column; an elastic net covering the cathode net; a surface net covering the elastic net; a fastening part penetrating through the surface net, the cathode net and the elastic net and is fixed on the conductive column. According to the electrolytic cell cathode provided by the invention, in the using process, the elastic cathode is uniformly attached to the ionic membrane, so that the shaking of the ionic membrane is reduced in the using process, and the service life of the ionic membrane can be greatly prolonged. The elastic net with special structure can effectively prevent the elastic change caused by pressure fluctuation and keep the polar spacing relatively stable. In the process of discharging gas, bubbles can be broken and the resistance inside the electric tank can be reduced. The elasticity of the elastic net is better and more durable, and the current density is uniform.

Description

TECHNICAL FIELD[0001]The present invention relates to an electrolytic cell, in particular to an electrolytic cell cathode with zero polar spacing or gap.BACKGROUND ART[0002]There are 128 elastic four-claws distributed on the cathode plate of an electrolytic cell to support the pole net, and the four-claws are welded to the pole net. The center of the elastic claw is provided with a pit or depression for hold a cylindrical pin with a PFA cap. During operation, under the action of 32 mandrels, the cathode plate and anode plate are tightly attached back to back, and the cathode plate bottom contacts the composite conductive block on the anode plate, and then electrical current is conducted in the electrolytic cell. The cathode cylindrical pin and anode cylindrical pin in the plate correspondingly press against the ionic membrane, and the cathode net and anode net also tightly press against the ionic membrane after being pressed.[0003]However, for the existing electrolytic cell, after b...
