The bracelet type aluminum alloy anode is a kind of insured product with the advantages of low driving voltage, light weight and high current efficiency.

Scope of application:

It is mainly used for anti-corrosion protection of oil, gas, and drainage pipelines, underground cables, chemicals, communications, harbors, ships, reservoir gates, etc. in fresh water. Bracelet zinc anodes are suitable for marine, anti-corrosion cathodic protection of ships, machinery, marine engineering and seaport facilities in seawater and freshwater media, as well as pipelines and cables in low-resistivity soils and sea mud.

Implementation standards:GB/T4950-2002

Production method:

Bracelet anode utilization has a great relationship with its existing structural form. Before casting, it can be designed and produced according to the specifications of the design institute. The specific analysis is as follows:

When the bracelet anode is connected to the protected cathode (such as a pipe, etc.), the semicircular anode body itself is continuously consumed, thereby suppressing the corrosion of the cathode in this way, and continuing when the anode body is consumed to the position of the core. Consumed until it is detached from the core, and the protection of the cathode is lost, but at this time, some anode bodies remain, and the anode bodies are not connected to the cathode, which has no function of cathodic protection, thus causing waste of the anode body material. That is, the above-mentioned problem of the utilization of the bracelet anode.

In the actual production process, the bracelet anode of the traditional structure will have the problem of core deformation due to the relatively large temperature difference between the iron core and the cast anode melt, so that the produced bracelet anode is difficult to meet the industry standard. (Industry standards require a distance between the core and the inner wall of the semicircular anode to be 4 mm). It can be seen from the above that the existing bracelet anode structure design does have defects, and it is necessary to change the structure to improve the current low utilization rate of the bracelet anode and the problem that the conventionally produced bracelet anode is difficult to meet the industry standard.
Technical realization elements:

The technical problem to be solved by the new "utility model" is to overcome the deficiencies in the prior art and provide a semi-circular bracelet anode body which has a unique structural design, can meet industry standards and can improve its utilization rate, and has the semicircle Bracelet anode for bracelet anode body.

The semicircular bracelet anode body comprises a semicircular annular anode body and an iron core, the iron core is penetrated in the semicircular annular anode body and both ends thereof pass through the semicircular annular anode body, and the iron core is fixed with a plurality of iron rods on the inner side of the iron core. The outer side is fixed with a plurality of positioning rods, the iron rod and the positioning rod are in the semicircular annular anode body, the top of the iron rod is flush with the inner wall of the semicircular annular anode body, and the top of the positioning rod is flush with the outer wall of the semicircular annular anode body.

The bracelet anode of the utility model is composed of a first semicircular bracelet anode body and a second semicircular bracelet anode body, and the two semicircular bracelet anode bodies adopt a semicircular bracelet of any of the above forms. The anode body, wherein the two ends of the core of the first semicircular bracelet anode body are respectively abutted with the two ends of the core of the second semicircular bracelet anode body.
