its selected sampling, as well as facilitating the flow of metal into the accumulator from interpolar spaces.

The goal is achieved by the fact that

the digger in contact with unipolar electrodes, in which inclined channels are made, which enter the compartment for collecting metal below the digger. In this case, the interpolar spaces are connected by channels located in the side walls of the electrolyzer.

FIG. 1 schematically shows an electrolysis cell, a longitudinal section; in fig. 2 - plan of the electrolyzer.

The main elements of the electrolyzer are the casing 1 lined with refractory material 2. Inside the electrolyzer is provided with cathode 3, anode 4, bipolar electrodes 5, compartment 6 for collecting and storing the resulting metal, channels 7 in the lining and channels 8 in the body of the electrode. At the top, the working space of the electrolyzer has an overlap of 9, through which the nozzles 10 in length pass. removal of gaseous electrolysis products. A pipe 11 is provided for loading the raw material. The bipolar electrodes 5 immersed in the electrolyte are mounted on the protrusions 12 formed by the lining of the bath shaft. In order to prevent oxidation and chlorination of the resulting metal, in the upper zone of the compartment a accumulator 13 is installed to accumulate it. The compartment 6 for collecting metal is equipped with a lid 14.

In the electrolytic production of metal (for example, magnesium), the electrolyte from the interpolar spaces through the channels 7 and 8 enters the compartment 6 and further, through the gap between the bottom and bottom of the electrodes, is transported to the interelectrode spaces. The resulting metal remains in compartment 6 and accumulates in the piggy 13, from which it is periodically removed by known methods. The chlorine-gas mixture is removed through nozzles 10.

The advantage of the proposed electrolyzer is that the presence of a compartment for accumulating and storing the metal obtained allows to protect the latter from anodic dissolution and interaction with the anode products (chlorine) and to minimize its loss. This allows maintaining a high current efficiency and having stable technical and economic indicators of the process, due to the centralized accumulation and removal of metal, labor costs are dramatically reduced.
