Abstract

An electrodic support structure for coaxial electrolytic cells suitable for operating in both monopolar and bipolar configuration is provided. The electrode support structure has a support plane made of an isolating material provided with a plurality of housing seats suitable for housing a plurality of electrodes arranged homothetically to each other, and a partition member made of insulating material, provided with a plurality of electrode positioning means, integral with or mechanically connected to the support plane and arranged orthogonally thereto.

First claim

1 . An electrodic support structure for coaxial electrolytic cells suitable for housing a plurality of electrodes comprising:
a support plane made of insulating material provided with a plurality of housing seats suitable for housing said plurality of electrodes; and a partition member made of insulating material integral with or mechanically connected to said support plane;
said partition member being a composite and continuous shaped member comprising a right-angled prism member equipped with a circular, elliptical, oval or polygonal shaped base with central symmetry; said right prism member having said base oriented in parallel to said support plane and being positioned at the centre of the base of said partition member placed at said support plane and being arranged orthogonally to said support plane; said partition member being provided with a plurality of positioning means suitable for positioning said plurality of electrodes,
at least one housing seat of said plurality of housing seats being arranged along an edge portion of said base of said right-angled prism member.

2 . The electrodic support structure according to claim 1 , wherein each housing seat comprises a groove and said partition member has at least one positioning means arranged at the at least one end of each of said grooves.

3 . The electrodic support structure according to claim 2 , wherein said positioning means are slits orthogonal to said support plane, each slit being arranged at one end of one said housing seat, each slit penetrating into said partition member in the direction of the tangent of said housing seat at the said end thereof.

4 . The electrodic support structure according to claim 1 , wherein said plurality of housing seats comprises a plurality of grooves, having a shape homothetic to each other.

5 . The electrodic support structure according to claim 1 , wherein said partition member has at least one through hole through two opposite surfaces thereof, said at least one through hole being suitable for the passage of electrolytic solution.

6 . The electrodic support structure according to claim 1 , wherein at least two housing seats of said plurality of housing seats are intercalated by one or more openings that pass through said support plane.

7 . The electrodic support structure according to claim 1 , wherein said support plane is provided with at least two pairs of housing seats, comprising:
an external pair of housing seats, said external pair being divided into a first external housing seat and a second external housing seat, said first and said second external housing seats being suitable for housing a pair of electrodes of the same dimensions, said first and said second external housing seats being separated from each other by said partition member; and an internal pair of housing seats, said internal pair being divided into a first internal housing seat and a second internal housing seat, said first and said second internal housing seats being suitable for housing a pair of electrodes of the same dimensions, said first and said second internal housing seats being separated from each other by said partition member.

8 . A coaxial electrolytic cell comprising:
the electrodic support structure according to claim 1 ; an insulating containing plane arranged parallel to said support plane; at least one containing side wall integral with or connected to said support plane and integral with or connected to said insulating containing plane and orthogonally interposed thereto; and a plurality of electrodes housed in said plurality of housing seats and positioned in said plurality of positioning means of said electrodic support structure;
said partition member and said plurality of electrodes being contained within the system comprising said electrodic support structure, said containing plane and said at least one containing side wall.

9 . The coaxial electrolytic cell according to claim 8 , wherein said insulating surface is provided with:
at least one inlet opening and at least one outlet opening for circulating an electrolytic solution within the system comprising said electrodic support structure, said insulating surface and said at least one side containing wall, and a plurality of openings suitable for the passage of one or more electrical connections for supplying electricity to said plurality of electrodes.
