[0029] Refer to Figure 1 、 Figure 2 and Figure 3 A kind of embodiment provided by the present utility model: A submerged arc furnace hollow electrode shell device, including the electrode shell 1 which is the metal shell in the submerged arc furnace for accommodating and supporting electrode paste. A support assembly is arranged on the outer wall of the electrode shell 1. The support assembly includes a support positioning plate 21 and two groups of positioning rings 2 of the electrode shell 1. The two groups of positioning rings 2 are symmetrically arranged. A positioning groove 25 for the sliding installation of the positioning plate 21 is opened on the inner wall of the positioning ring 2.

The cooperation between the first connecting block 3 and the second connecting block 33 can connect two groups of positioning rings 2, so that after multiple groups of electrode shells 1 are connected, they can be used to easily hold and support electrode paste. The first connecting block 3 is fixedly connected to the right side of the positioning ring 2, and the second connecting block 33 is fixedly connected to the left side of another group of positioning rings 2. A connecting groove 34 is formed on the front surface of the first connecting block 3, which is convenient for the connecting plate 31 to slide in and cooperate with the round rod 32 to slide into the first round groove 35 to limit the connecting plate 31, so that the first connecting block 3 and the second connecting block 33 can be connected.

[0031] Refer to Figure 1 , Figure 2 and Figure 4 , a plurality of limiting rods 23 are fixedly connected to the inner wall of the guide plate 22 corresponding to the limiting rods 23 of the plurality of positioning plates 21 and the electrode shell 1. The limiting rods 23 are inserted into the inner wall of the limiting groove 24. There are multiple groups of positioning grooves 25, electrode shells 1, positioning plates 21, limiting grooves 24, and limiting rods 23, and the multiple groups of positioning grooves 25, electrode shells 1, positioning plates 21, limiting grooves 24, and limiting rods 23 are evenly arranged on the inner wall of the positioning ring 2. After multiple groups of electrode shells 1 are installed, they form a circular ring shape, so that they can be used to hold and support electrode paste in a submerged arc furnace. The multiple groups of positioning grooves 25, positioning plates 21, limiting rods 23, and limiting grooves 24 are arranged in one-to-one correspondence. A convex block is fixedly connected to the front surface of the positioning plate 21, which can support the top of the positioning ring 2 to support the positioning plate 21. Both the positioning ring 2 and the guide plate 22 are arc-shaped. After two groups of arc-shaped positioning rings 2 are connected, they can form a circular ring shape, so that they can be used to hold and support electrode paste.

[0032] Refer to Figure 2 , Figure 3 and Figure 4 , a second round groove 36 is formed on the bottom inner wall of the connecting groove 34. The round rod 32 passes through the first round groove 35 and then slides into the second round groove 36, so that the connecting plate 31 can be limited, and the first connecting block 3 and the second connecting block 33 can be connected and installed with limited position. A round rod 32 that can pass through the first round groove 35 and slide into the second round groove 36 to limit the connecting plate 31 penetrates and is slidably connected above the connecting groove 34 at the top of the first connecting block 3. A connecting plate 31 that can slide into the connecting groove 34 and cooperate with the round rod 32 to pass through the first round groove 35 and slide into the second round groove 36 to connect and install the first connecting block 3 and the second connecting block 33 is rotatably connected to the front surface of the second connecting block 33. The connecting plate 31 slides on the inner wall of the connecting groove 34.

[0033] Refer to Figure 1 , Figure 3 and Figure 4The top of the connecting plate 31 is provided with a circular groove 35 that cooperates with the round rod 32 and the connecting block 3 to limit the connecting plate 31. The round rod 32 penetrates and slides on the inner wall of the circular groove 35. The round rod 32 penetrates the circular groove 35 and slides on the inner wall of the circular groove 2 36. The left side of the connecting plate 31 is fixedly connected with a dial block that can be moved to drive the connecting plate 31 to rotate. There are two groups of connecting blocks 1 3 and 2 33. The two groups of connecting blocks 1 3 and 2 33 are symmetrically arranged at the rear ends of the two groups of positioning rings 2 with the center line of the positioning ring 2 as the symmetry axis. The two groups of positioning rings 2 can be connected to form a circular ring shape through the two groups of connecting blocks 1 3 and 2 33 in cooperation with the two groups of round rods 32 and the connecting plate 31, so that they can be used to accommodate and support electrode paste.

[0034] Working principle: When in use, the initial installation and positioning is achieved by inserting the positioning plate 21 fixedly connected to the outer wall of the electrode shell 1 into the positioning groove 25 opened on the inner wall of the positioning ring 2. After the positioning plate 21 is inserted into the positioning groove 25, after multiple groups of electrode shells 1 are installed, the guide plate 22 is rotated so that the limiting rod 23 fixedly connected to the inner wall is inserted into the limiting groove 24 opened on the right side of the positioning plate 21. Multiple groups of positioning grooves 25, electrode shells 1, positioning plates 21, limiting grooves 24 and limiting rods 23 cooperate with each other to quickly limit and fix multiple groups of electrode shells 1.

[0035] When multiple groups of electrode shells 1 need to be connected, the connecting block 1 3 is brought into contact with the connecting block 2 33, and the round rod 32 is moved upward to slide out of the connecting groove 34. The block is moved to drive the connecting block 2 33 to rotate, and the connecting plate 31 connected to the front surface of the connecting block 2 33 is driven to slide into the connecting groove 34 opened on the front surface of the connecting block 1 3. At this time, the round groove 1 35 is aligned with the round rod 32. At this time, the round rod 32 is moved downward so that the round rod 32 passes through the round groove 1 35 and continues to slide into the round groove 2 36 opened on the inner wall of the bottom end of the connecting groove 34. The connecting plate 31 is limited to realize the connection between the connecting block 1 3 and the connecting block 2 33. The two groups of connecting blocks 1 3 and the connecting block 2 33 cooperate with the two groups of round rods 32 and the connecting plate 31 to connect the two groups of positioning rings 2 to form a circular ring shape, which plays a better supporting and connecting role for the multiple groups of electrode shells 1. After the multiple groups of electrode shells 1 are installed, a circular ring shape is formed to accommodate and support the electrode paste. At this time, the electrode paste can be filled in the circular ring-shaped electrode shell 1, and the circular ring-shaped electrode shell 1 can stably accommodate and support the electrode paste in the electric arc furnace.

[0036] When a local damage occurs to the electrode housing 1, the rotation guide plate 22 drives the limit rod 23 to slide out of the limit groove 24, releasing the limit on the electrode housing 1. At this time, the damaged electrode housing 1 can be removed upward for replacement, improving the operation convenience. Meanwhile, there is no need for overall disassembly and recombination, reducing the consumption of resources and costs, shortening the maintenance time, and improving the production efficiency. When it is necessary to disassemble and separate the positioning ring 2, the round rod 32 is slid out of the second round groove 36 and the first round groove 35, and the connecting plate 31 is slid out of the connecting groove 34, then the separation of the positioning ring 2 can be realized. The operation is convenient, improving the disassembly and assembly efficiency and the processing efficiency.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features.
