Abstract
In electrolysis of iron, the cathode suspended by springs, which have moderate elasticity and amplitude, is used. When electrolysis is carried on the cathode is blowed periodically by a hammer and oscillated.
The mechanism of the system: -
(a) Regulating the weight or the height of the hammer, the force of its blow on the cathode and consequent the maximum velocity of the oscillating cathode can be altered.
(b) The amplitude of the oscillation can be altered by altering the spring elasticity.
(c) The period of blows can be altered by altering the speed of revolution of the cam with which the hammer is handled.
The effects of oscillating cathode: -
(1) The suspentions in the electrolyte are swept off from the cathode surface.
(2) The diminuation of Fe ions on the cathode layer is prevented.
(3) The hydrogen babbles on the cathode surface are swept off.
(4) The accumlation of Fe-salt on the anode layer is prevented.
(5) The slime is swept off from the anode surface.
(6) The temperature and the concentration of the electrolyte are equalized.
