Problems solved by technology

[0002] At present, in the process of electrolytic aluminum, it is necessary to put the anode plate (carbon electrode) into the electrolyte in the electrolytic cell for chemical reaction. During the reaction, fluoride ions, oxygen ions and oxygen will be produced. After contact, a large amount of products such as carbon dioxide, carbon monoxide and hydrogen fluoride will be produced, which will cause great damage to the environment

Embodiment 1

[0013] Embodiment 1: as figure 1 , 2 As shown, an electrolytic aluminum anode device includes an anode plate 2 located in an electrolytic cell 1, a protective cover 3 is arranged on the outer wall of the anode plate 2, and a protective cover 3 is laterally connected to the lower end outer wall of the protective cover 3. The inner cavity of the protective cover 3 communicates with the isolation cavity 4 .

Embodiment 2

[0014] Embodiment 2: the anode device that has isolation cavity 4 and protective cover 3 can be many sets, as image 3 shown.

[0015] In the present invention, the number of isolation cavities 4 can be 2, and they are correspondingly arranged on the outer wall of the protective cover 3; Of course, multiple isolation cavities 4 can also be set according to actual needs.

[0016] In the present invention, the vertical current from the anode to the cathode first flows horizontally through the isolation chamber 4, and then flows vertically to the cathode, thus changing the direction of movement of the current. The aluminum oxide in the electrolyte in the electrolytic cell is electrolyzed, the gas is evacuated, and the metal sinks to the bottom of the cell. The electrolyte entering the isolation chamber 4 is in a relatively static state, and there is no aluminum oxide in normal operation, so there is no oxygen on the surface of the anode plate 2, thereby protecting the anode fro...

Description

technical field [0001] The invention relates to an electrolytic aluminum anode device. Background technique [0002] At present, in the process of electrolytic aluminum, it is necessary to put the anode plate (carbon electrode) into the electrolyte in the electrolytic cell for chemical reaction. During the reaction, fluoride ions, oxygen ions and oxygen will be produced. After contact, a large amount of products such as carbon dioxide, carbon monoxide and hydrogen fluoride will be produced, which has caused great damage to the environment. Contents of the invention [0003] The object of the present invention is to provide an electrolytic aluminum anode device capable of preventing carbon dioxide, carbon monoxide and oxygen from reacting with the anode plate. [0004] The object of the present invention is achieved through such a technical scheme, an electrolytic aluminum anode device, comprising an anode plate located in the electrolytic cell, a protective sleeve is arra...
