Embodiment 1

[0038] electrolytic furnace (see figure 1 , Figure 5 and Figure 9 ), including feed pipe 1, exhaust hole 2, anode adjustment part 3, furnace cover 4, furnace chamber 5, furnace wall 6, shell 7, cathode 8, anode 9, crucible 10, insulation layer 16, guide ring 19 and Waterproof insulation part 20. From the outside to the inside are the shell 7, the insulation layer 16, the furnace wall 6, and the furnace 5. The cavity in the furnace wall 6 forms the furnace 5 with an open top. From top to bottom are the anode adjustment part 3 , the furnace cover 4 , the furnace 5 , the anode 9 , the cathode 8 and the crucible 10 . The furnace cover 4 is covered above the opening of the furnace 5 . The number of the anode adjustment part 3, the anode 9, the cathode 8 and the crucible 10 is 1 each, and the cross section of the cathode 8 is circular, located in the furnace 5, and the two ends pass through the furnace wall 6, the insulation layer 16 and the shell respectively. 7 protrudes ou...

Embodiment 2

[0044] electrolytic furnace (see figure 1 , Figure 5 and Figure 9 ). This embodiment is basically the same as Embodiment 1, except that the number of the anode adjustment part 3, the anode 9, the cathode 8, the crucible 10, the guide ring 19 and the guide rod 31 is 2 pieces each, and the anode 9, the cathode 8 and the crucible 10 are arranged in parallel in the furnace 5 in pairs. Each of the cathodes 8 is inclined at 3° relative to the horizontal plane along the length direction. The two pieces of crucibles 10 are communicated with each other and come out of the furnace together. Each cathode 8 is inclined relative to the horizontal plane along the length direction so that the product leaves the electrolysis reaction area faster, which is beneficial to concentration and collection.

[0045] Compared with Embodiment 1, this embodiment improves the utilization rate of the furnace 5 and has a large production capacity, which is conducive to the enlargement of the electrol...

Embodiment 3

[0047] electrolytic furnace (see figure 2 , Image 6 , Figure 7 , Figure 10 , Figure 11 and Figure 12 ), including feed pipe 1, exhaust channel 2, anode adjustment part 3, furnace cover 4, furnace chamber 5, furnace wall 6, shell 7, cathode 8, anode, crucible 10, insulation layer 16, guide ring 19 and anti Insulation part 20. From the outside to the inside are the shell 7, the insulation layer 16, the furnace wall 6, and the furnace 5. The cavity in the furnace wall 6 forms the furnace 5 with an open top. From top to bottom are the anode adjustment part 3 , the furnace cover 4 , the furnace 5 , the anode, the cathode 8 and the crucible 10 . The furnace cover 4 is covered above the opening of the furnace 5 . There are two anode adjustment components 3, and one anode, one cathode 8 and one crucible 10 each. Described cathode 8 is circular in cross section, is located in furnace 5, and one end passes through furnace wall 6, insulation layer 16 and casing 7 and stretc...

Abstract

The invention discloses an electrolytic furnace. The electrolytic furnace comprises a shell (7), a heat preservation layer (16), a furnace wall (6) and a hearth (5) from outside to inside. The hearth (5) with an opening in the top is formed in a cavity in the furnace wall (6); an anode adjusting component (3), the heath (5), an anode (9) and a cathode (8) are arranged from top to bottom; the cathode (8) is located in the hearth (5), and at least one end penetrates the furnace wall (6), the heat preservation layer (16) and the shell (7) and stretches out of the shell (7); the anode (9) stretches into the hearth (5) from the top of the hearth (5), and an electrolytic work pair is formed by the anode (9) and the cathode (8); the anode adjusting component (3) controls the anode (9) to move; and the anode (9) is provided with an exhaust channel (2). The electrolytic furnace has the beneficial effects that during electrolytic operation, generated gas can be conveniently escaped, anode uniform consumption and electrolytic technology parameter control is convenient, discharging is convenient, the anode utilization rate is high, the staying time of products in the electrolytic reaction area is short, the yield is high, and the product quality is more uniform.
