[0018] In order to solve the problem that only the outer arc surface of the graphite anode has residual reaction during the electrolysis process, multiple anode structures need to be arranged at the same time to ensure the electrolysis efficiency, which will lead to an increase in anode consumables during the entire electrolysis reaction; please refer to Figure 1-3 , the utility model provides the following solutions:

[0020] The engaging shaft groove 103 between the lower electrolytic sheet 101 and the mounting buckle plate 102 is mounted on the inner wall of the top of the furnace body, wherein the lower electrolytic sheet 101 is located inside the furnace body, and the mounting buckle plate 102 is located outside the furnace body. A gap is left between the lower electrolytic sheet 101 and the furnace wall. During the electrolysis reaction, the electrolyte inside the furnace body will contact the entire lower electrolytic sheet 101, so that the electrolysis efficiency of the lower electrolytic sheet 101 can be guaranteed;

[0021] The partition support shaft 2 is located above the anode hoop sheet 1, and its main function is to separate the anode hoop sheet 1 from the cover plate structure to prevent the current passing through the anode hoop sheet 1 from being transmitted upward to the cover plate structure during the electrolysis reaction, thereby reducing the risk of electric shock and internal combustion;

[0022] The lower electrolytic sheet 101 is set to an arc-shaped structure, and a plurality of reflux holes 1011 are set on the outer surface of the lower electrolytic sheet 101, and the reflux holes 1011 extend through and extend to the surfaces of both sides of the lower electrolytic sheet 101. An insulating pad 1021 is set below the mounting gusset plate 102, and the insulating pad 1021 is fitted and connected to the mounting gusset plate 102. A plurality of metal probes 104 are set at the bottom of the mounting gusset plate 102, and the metal probes 104 extend to the inside of the mounting gusset plate 102.

[0023] During the reaction, the liquid in the furnace body can flow through the reflux holes 1011 on the surface of the lower electrolytic sheet 101, which can not only increase the contact area between the lower electrolytic sheet 101 and the liquid, but also improve the fluidity of the liquid, so that the liquid can participate in the reaction more evenly.

[0024] Working principle: the engaging shaft groove 103 between the lower electrolytic sheet 101 and the mounting buckle plate 102 is installed on the inner wall of the top of the furnace body, wherein the lower electrolytic sheet 101 is located inside the furnace body, and the mounting buckle plate 102 is located outside the furnace body. There is a gap between the lower electrolytic sheet 101 and the furnace wall. During the reaction, the liquid in the furnace body can flow through the reflux hole 1011 on the surface of the lower electrolytic sheet 101, which can not only increase the contact area between the lower electrolytic sheet 101 and the liquid, but also improve the fluidity of the liquid, so that the liquid can participate in the reaction more evenly.
