3. in electrochemical applications, unavoidable all have a current density uneven phenomenon, large-area especially more pole plate, and edge current is higher than central authorities during energising, and voltage is high more more obvious.So, electrode surface is cut apart again, can improve the problem of current density inequality.And novel material electrode such as activated carbon fiber or rice carbon gas gel electrode tool flexibility how; Cooperate the utility model to make electrode surface become arcuation, current unevenness can improve.

4. in electrochemistry, use special film or spacer, to carry out specific redox or separation and purification purpose.Yet this film or spacer are in operating process, if the upholder that do not have to be fit to easily pulls, is out of shape because of hydraulic pressure causes, and then cause and break, especially fractal key more when large-area applications.

The utility model content

The purpose of this utility model is to provide a kind of electrochemistry to use the improved structure of equipment, for electrode surface is cut apart, high and low Current Zone is heavily distributed again, thereby add the disturbance of big flood or air, reach the effect that the short circuit of minimizing negative electrode, enhancing scale removal, support membrane or barrier material and gas divest.

The utility model comprises symmetric grid member, and the battery lead plate that is folded in grid member, wherein, these grid member are provided with a framework, be provided with spaced plurality of fixed hole in framework, sealed by fixed orifices for inserting and putting behind the battery lead plate, the framework inner edge is provided with staggered vertical, horizontal glazing bar, makes the vertical, horizontal glazing bar be made as the arrangement of geometrical shape.

The utility model is provided with the pedestal of a frame shape, in the upper and lower edge of pedestal be provided with out respectively, water inlet or deslagging, aeration outlet, apical margin then is provided with one and cuts open the hole for inserting battery lead plate, after grid member is folded in this pedestal, for film being installed in grid member or being separated material, and when installing by the horizontal glazing bar of grid member as supporting layer.

The periphery of this pedestal and grid member wherein is respectively equipped with corresponding plurality of fixed hole, sealed by this fixed orifices, and it is fixing that grid member and pedestal are inserted and put.

The vertical, horizontal glazing bar of this grid member wherein is made as the arrangement mode of honeycomb, trilateral, circle, vertical bar shaped, horizontal stripe shape or other geometrical shape.

Advantage of the present utility model is: it is provided with the grid member of vertical, horizontal glazing bar, cooperate pedestal and battery lead plate, constitute electrochemistry and use the improved structure of equipment, for electrode surface is cut apart, high and low Current Zone is heavily distributed again, thereby add the disturbance of big flood or air, reach and reduce the effect that negative electrode short circuit, enhancing scale removal and gas divest.
