Abstract
For use in assembly of elongate sacrificial anodes consumed in process containers, apparatus for aligning and connecting anode sections to form a single segmented anode is disclosed wherein the aligning and connecting apparatus is composed of the same or similar sacrificial material. In the preferred and illustrated embodiment, a graphite collar member cooperative with a graphite threaded pin is set forth. The two are used in conjunction with a drilled and tapped bottom socket formed in a rectangular graphite mode block; preferably, duplicate systems are used on symmetrical sides to string several graphite anode blocks together in conjunction with a tapered counterbore at the end of a drill passage through the graphite block.
Claims19
A sacrificial anode comprising an elongate graphite anode body having first and second end faces and first and second similar threaded graphite connector means connecting to said body to support a similar graphite anode body, said connector means having:
- (a) collar means with an internal axially hollow passage;
- (b) separate headed pin means received in said collar means for securing said pin means thereby at the head;
- (c) said collar means having a thread of one hand for engagement with the thread of said body;
- and
- (d) said pin means having a threaded extending portion to join to a second and similar body wherein the threads are of the opposite hand.
A segment sacrificial anode for electrochemical process comprising:
- (a) a plurality of substantially identical anode sections of generally rectangular cross-section composed of sacrificial material compatible with said process, each anode section forming:
- (1) side surfaces of generally planar form;
- (2) generally planar upper and lower end surfaces of substantially parallel relation;
- (3) upper threaded socket means intersecting said upper end surface;
- (4) lower threaded socket means intersecting said lower end surface;
- (b) pin means of sacrificial material having a head portion receivable within said lower socket means and a threaded portion extending downwardly below said lower end surface means for threaded connection within said upper threaded socket means of a lower anode section;
- and
- (c) collar means of sacrificial material being threadedly received within said lower socket means and receiving said pin means therein, said collar means securing said pin means in rotatable assembly with said anode section.
