A sliding groove 4 is provided on the circumferential surface of the positioning cylinder 3. A positioning block 5 is slidably provided in the sliding groove 4. The end of the positioning block 5 away from the center of the positioning cylinder 3 has a guide slope 6. The distance between the lower end of the guide slope 6 and the center of the positioning cylinder 3 is less than the distance between the upper end of the guide slope 6 and the center of the positioning cylinder 3. A first elastic element 7 is provided in the sliding groove 4. The first elastic element 7 is located between the positioning block 5 and the bottom of the sliding groove 4. The two ends of the first elastic element 7 are respectively fixed on the positioning block 5 and the bottom of the sliding groove 4. When the first elastic element 7 is in its natural state, the guide slope 6 is located outside the circumferential surface of the positioning cylinder 3.

[0023] When installing the suspended chute into the aluminum electrolysis cell gantry frame, the suspended chute is dragged so that the positioning cylinder 3 is inserted into the mounting hole on the gantry frame. When the guide slope 6 of the positioning block 5 contacts the gantry frame, the positioning block 5 is gradually pushed back into the slide groove 4 of the positioning cylinder 3 as the positioning cylinder 3 is inserted. The first elastic element 7 is compressed. After the positioning cylinder 3 is fully inserted into the mounting hole on the gantry frame, the first elastic element 7 is reset, and the positioning block 5 is inserted into the gantry frame, thereby pre-fixing the suspended chute to the gantry frame. Then, the screws are tightened to fix it, thus achieving the purpose of facilitating the installation of the suspended chute into the aluminum electrolysis cell gantry frame and improving installation efficiency.

[0024] In this embodiment, a rotating block 8 is rotatably connected to the positioning cylinder 3. A first pull rope channel 9 is provided inside the positioning cylinder 3. One end of the first pull rope channel 9 connects to the bottom of the chute 4, and the other end connects to the rotating block 8. A first pull rope 10 is provided inside the first pull rope channel 9. One end of the first pull rope 10 is connected to the positioning block 5, and the other end is connected to the rotating block 8. Specifically, in this embodiment, the rotating block 8 is a hexagonal block. With the rotating block 8 and the first pull rope 10, when disassembling the suspended chute, the hexagonal block can be rotated using a wrench. After the hexagonal block rotates, the first pull rope 10 is pulled, thereby pulling the positioning block 5 back into the chute 4. Then, the suspended chute can be dragged for disassembly. Reversing the rotation of the hexagonal block, under the elastic force of the first elastic element 7, the positioning block 5 returns to its original position.

[0025] In this embodiment, the first elastic element 7 is a spring. Other elastic elements with elastic functions can also be selected.

[0026] In this embodiment, a protective component is provided on the inner wall of the tank 1. This component includes multiple U-shaped blocks 11 arranged sequentially along the length of the tank 1. A sealing ring, which is a high-temperature resistant sealing ring, is provided between adjacent U-shaped blocks 11. In this embodiment, the sealing ring is a ceramic fiber sealing ring. By using the U-shaped blocks and the high-temperature resistant sealing ring, the electrolyte flows on the U-shaped blocks 11 without directly contacting the tank 1, thus preventing corrosion of the tank 1 by the electrolyte and improving the service life of the tank 1.

[0027] In this embodiment, a positioning component 12 is provided between the U-shaped block 11 and the groove 1. The positioning component 12 includes a second positioning block 13 and a second elastic element 14.

The second positioning block 13 is slidably disposed in the positioning slide groove 16. The second elastic element 14 is disposed in the positioning slide groove 16 and located between the second positioning block 13 and the bottom of the positioning slide groove 16. The two ends of the second elastic element 14 are respectively connected to the second positioning block 13 and the bottom of the positioning slide groove 16. The second elastic element 14 provides a spring force to drive the second positioning block 13 to slide and enter the positioning groove 15. Specifically, in this embodiment, the second positioning block 13 is a cube. Under the elastic force of the second elastic element 14, the second positioning block 13 is inserted into the positioning groove 15, fixing the U-shaped block 11 to the groove 1.

[0028] In this embodiment, a second pull rope channel 17 is provided inside the groove 1. One end of the second pull rope channel 17 is connected to the bottom of the positioning slide groove 16, and the other end is connected to the outside of the groove 1. A second pull rope 18 is provided inside the second pull rope channel 17. One end of the second pull rope 18 is connected to the second positioning block 13, and the other end extends outward from the second pull rope channel 17. When it is necessary to disassemble the U-shaped block 11, pull the second pull rope 18, and the second positioning block 13 is pulled back into the positioning slide groove 16, disengaging from the positioning groove 15. Then, the U-shaped block 11 can be disassembled. After releasing the second pull rope 18, the second positioning block 13 resets.

[0029] The second elastic element 14 is a spring. Other elastic elements with elastic functions can also be selected.

[0030] When using a suspended chute, the tank body 1 is installed on the gantry frame of the aluminum electrolysis cell. The aluminum electrolyte flows into the aluminum electrolysis cell through the tank body 1. When installing the suspended chute onto the gantry frame, the chute is dragged, causing the positioning cylinder 3 to insert into the mounting hole on the gantry frame. When the guide slope 6 of the positioning block 5 contacts the gantry frame, the positioning block 5 is gradually pushed back into the groove 4 of the positioning cylinder 3 as the positioning cylinder 3 is inserted. The first elastic element 7 is compressed. After the positioning cylinder 3 is fully inserted into the mounting hole, the first elastic element 7 resets, and the positioning block 5 is inserted into the gantry frame, thus pre-fixing the suspended chute to the gantry frame. Then, the screws are tightened for final fixation, facilitating the installation of the suspended chute onto the aluminum electrolysis cell gantry frame. When it is necessary to disassemble the suspended chute, the hexagonal block is rotated using a wrench. After the hexagonal block rotates, the first pull rope 10 is pulled, thereby pulling the positioning block 5 back into the groove 4. Then, the suspended chute is dragged for disassembly. By setting up the U-shaped block 11 and the high-temperature resistant sealing ring, the electrolyte flows on the U-shaped block 11 without directly contacting the tank body 1, thus avoiding corrosion of the tank body 1 by the electrolyte and improving the service life of the tank body 1. The U-shaped block 11 is fixed by inserting the second positioning block 13 into the positioning groove 15 of the U-shaped block 11; by pulling the second pull rope 18, the second positioning block 13 is pulled back into the positioning slide 16 and disengaged from the positioning groove 15, the second elastic element 14 is compressed, then the U-shaped block 11 is removed, the second pull rope 18 is released, and the second elastic element 14 returns to its original position with the second positioning block 13.
