Problems solved by technology

No matter which method is very clumsy, it is difficult to meet the production requirements
Because the old method is realized by human experience, it is very unscientific, and the aluminum cannot be extracted in time, which will increase the aluminum level, cause the secondary oxidation of aluminum water, increase the heat loss, make the operation of the electrolytic cell unstable, reduce the electrolysis efficiency, and reduce the aluminum production process. labor intensive

Embodiment Construction

[0030] The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited by the embodiments.

[0031] As shown in Fig. 1, Fig. 2, Fig. 4 and Fig. 5, the structure of the DC electromagnetic pump for the aluminum electrolytic cell of the present invention is as follows: the pump body 2 of the electromagnetic pump is an L-shaped tubular structure, and the pump body 2 of the electromagnetic pump can be made of alumina refractory concrete once Pounded into shape; the two ends of the pump body 2 of the electromagnetic pump are inlet and outlet, the diameter of the inlet end is larger than the diameter of the outlet end, and the middle is a liquid channel. The cathode 5 is arranged at the L angle in the pump body 2 of the electromagnetic pump, and the two sides are the same The position corresponds to the magnetic guide plate 4, and the two magnetic guide plates 4 a...

Abstract

The invention discloses an electromagnetic pump especially a source-free direct current electromagnetic pump, which is characterized by the following: setting pump body (2) as L shape structure; arranging negative pole at L angle position of the pump body (2); arranging magnetic conduction plate (4) on the two laterals of the L angle in the pump body (2); connecting the two magnetic conduction plates to N pole and S pole of electromagnet (6) separately; constructing the negative pole 5 and the magnetic conduction plate (4) as component of pump groove; nesting energizing coil (8) on the electromagnet (6); connecting the negative (5) and the energizing coil (8) to site control pod. This invention possesses simple structure, liable work and small volume.

Description

technical field [0001] The invention relates to an electromagnetic pump, in particular to a passive direct-current electromagnetic pump used for transporting metal liquid, which is suitable for aluminum electrolysis tank. Background technique [0002] With the rapid development of the aluminum industry, newly-built electrolytic aluminum plants are becoming more and more large-scale, and the wide application of large-scale electrolytic cells of 100,000 to 200,000 tons and 300,000 to 400,000 amperes has put forward severe requirements for the electrolytic aluminum production process. : Not only the amount of aluminum produced is large, but also the aluminum produced must be produced in a timely manner. At present, the method of aluminum extraction basically adopts two methods of vacuum pump or jet pump. No matter which method is very clumsy, it is difficult to meet the production requirements. Because the old method is realized by human experience, it is very unscientific, a...
