Description

Technical Field

[0001] This utility model relates to the technical field of anode feeding auxiliary devices, specifically an anode feeding auxiliary device for an aluminum electrolysis cell. Background Technology

[0002] An aluminum electrolytic cell is a device used to produce electrolytic aluminum. Because the anodes in an aluminum electrolytic cell are constantly consumed, they need to be replaced periodically. After replacement, an alumina-crystal mixture is typically used as the anode covering material to achieve heat preservation and prevent anode oxidation. A search revealed patent application number 202421096923.7, which discloses an anode feeding auxiliary device for an aluminum electrolytic cell. This device includes a cell bottom shell, a main baffle, and a discharge port baffle. The main baffle is detachably mounted on the cell bottom shell. A triangular support plate is fixedly connected to one side of the main baffle and engages with the cell bottom shell. The upper end of the main baffle is inclined towards the triangular support plate. A handle is fixedly connected to the discharge port baffle and detachably mounted on the cell bottom shell. A positioning plate is provided at the tail of the handle and is fixedly connected to the handle, engaging with the cell bottom shell.

[0003] However, in actual use, the applicant found that when adding covering material, some of it easily enters the slots and the connection between the discharge port baffle, positioning plate, and main baffle. After being heated and solidified, it forms a hard adhesive, severely hindering the disassembly of the main baffle and discharge port baffle. Simultaneously, the discharge port baffle is directly attached to the discharge port, and the solidified covering material easily causes them to stick together, further increasing the difficulty of disassembly. Furthermore, the connection stability between the main baffle and the bottom shell of the electrolytic cell is insufficient; under the lateral pressure of the covering material or the influence of equipment vibration, it is prone to displacement and cannot be stably maintained in the preset position, causing the covering material to roll away from the anode, making it difficult to ensure effective coverage of the anode, thus affecting the heat preservation and anti-oxidation effects. In view of this, this application proposes an auxiliary device for anode feeding in an aluminum electrolytic cell to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary device for feeding the anode of an aluminum electrolysis cell, which solves the problems of existing devices where the covering material easily enters the slot, solidifies and sticks at the connection, hindering disassembly, the discharge port baffle is easily solidified when it is attached to the discharge port, increasing the difficulty of disassembly, and the main baffle is easy to shift, causing the covering material to roll off, affecting the anode covering and heat preservation and anti-oxidation effects.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary device for anode feeding in an aluminum electrolytic cell, comprising an electrolytic cell bottom shell, a material blocking mechanism slidably engaged with the upper side of the electrolytic cell bottom shell for blocking covering material, and two longitudinal partitions spaced apart on the upper side of the electrolytic cell bottom shell. The material blocking mechanism is engaged with the two longitudinal partitions. The material blocking mechanism includes a main baffle slidably engaged with the upper side of the electrolytic cell bottom shell, a slot formed on the lower side of the main baffle and adapted to the longitudinal partitions, a support component on one side of the main baffle for supporting the main baffle, a discharge port baffle and a positioning plate respectively fixedly connected to both ends of the main baffle, a partition plate slidably connected to one side of the discharge port baffle, and two positioning mechanisms symmetrically arranged on one side of the main baffle. The two positioning mechanisms are respectively inserted into the two longitudinal partitions. The opposite sides of the discharge port baffle and the positioning plate abut against the two sides of the electrolytic cell bottom shell. The positioning mechanisms, the support component, and the partition plate are all located on the same side of the main baffle.

[0006] Furthermore, each of the two longitudinal partitions has a plurality of spaced positioning holes on its opposite side; the positioning mechanism includes an L-shaped fixing bracket connected to one side of the main baffle, and a positioning bolt threaded to the vertical section of the L-shaped fixing bracket and inserted into the positioning hole.

[0007] Furthermore, the support assembly includes three triangular support plates that are perpendicularly connected to one side of the main baffle and arranged side by side at equal intervals, a transverse rib plate disposed between two adjacent triangular support plates, and two handles connected to one side of the main baffle; the two handles are respectively located above the two transverse rib plates; the two L-shaped fixing brackets are respectively located below the two transverse rib plates; one side of the transverse rib plate is connected to one side of the main baffle plate.

[0008] Furthermore, the lower side of the triangular support plate is provided with anti-slip texture.

[0009] Furthermore, the discharge port baffle has two spaced T-shaped connecting slots on the side near the triangular support plate, and the upper end of the T-shaped connecting slots is connected to the upper side of the discharge port baffle; the partition plate has two spaced T-shaped connecting blocks on the side near the discharge port baffle, and the T-shaped connecting blocks are slidably engaged with the T-shaped connecting slots.

[0010] Furthermore, the upper side of the partition plate is provided with a folding handle.

[0011] Furthermore, the inner wall of the slot is provided with an alumina ceramic bushing.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention, by fixing the discharge port baffle and positioning plate to both ends of the main baffle, prevents the covering material from seeping into the connection between the main baffle and the baffle, thus preventing the covering material from solidifying and hindering the disassembly of the main baffle and the discharge port baffle. Furthermore, by pulling the partition plate out from between the discharge port baffle and the discharge port, a certain distance is maintained between them, facilitating the movement of the main baffle and the discharge port baffle away from the forming covering material, thus improving the ease of disassembly from the bottom shell of the electrolytic cell. Simultaneously, the snap-fit ​​mechanism between the material-blocking mechanism and the longitudinal partition plate, combined with the insertion and fixing of the positioning mechanism, ensures that the main baffle is stably positioned in a preset position (e.g., 10 cm from the outer edge of the anode), reliably preventing the covering material from rolling away from the anode, ensuring effective coverage of the anode, and further enhancing the practicality and stability of the device.

[0015] Please see Figure 1-4An auxiliary device for anode feeding in an aluminum electrolytic cell includes an electrolytic cell bottom shell 1, a material blocking mechanism that slides on the upper side of the bottom shell 1 to block covering material, and two longitudinal partitions 2 welded and fixed to the upper side of the bottom shell 1 at intervals. The material blocking mechanism is engaged with the two longitudinal partitions 2. The material blocking mechanism includes a main baffle 3 that slides on the upper side of the bottom shell 1, a slot on the lower side of the main baffle 3 that is adapted to the longitudinal partitions 2, a support component on one side of the main baffle 3 for supporting the main baffle 3, a discharge port baffle 4 and a positioning plate 5 that are fixedly connected to both ends of the main baffle 3, a partition plate 6 that slides on one side of the discharge port baffle 4, and two positioning mechanisms that are symmetrically arranged on one side of the main baffle 3. The two positioning mechanisms are respectively inserted into the two longitudinal partitions 2. The opposite sides of the discharge port baffle 4 and the positioning plate 5 abut against the two sides of the bottom shell 1 of the electrolytic cell. The positioning mechanisms, the support component, and the partition plate 6 are all located on the same side of the main baffle 3.

[0016] Each of the two longitudinal partitions 2 has multiple spaced positioning holes 13 along its length on opposite sides. The positioning mechanism includes an L-shaped fixing bracket 14 welded perpendicularly to one side of the main baffle 3, and a positioning bolt 15 threadedly connected to the vertical section of the L-shaped fixing bracket 14 and inserted into the positioning hole 13. The spacing of the positioning holes 13 is adapted to the adjustment requirements of the main baffle 3. The vertical section of the L-shaped fixing bracket 14 has an internal threaded hole, and the positioning bolt 15 is threadedly connected to this threaded hole. The cooperation between the positioning holes 13 and the positioning bolt 15 of the longitudinal partitions 2 enables the main baffle 3 to be fixed in different positions. By selecting different positioning holes 13, the distance between the main baffle 3 and the anode can be adjusted (e.g., controlled at 10 cm), meeting the blocking requirements of different covering material thicknesses, and further enhancing the positional stability of the main baffle 3, preventing the main baffle 3 from being affected by unilateral force displacement and thus the material blocking effect.

[0017] The support assembly includes three triangular support plates 7, perpendicularly welded to one side of the main baffle 3 and arranged at equal intervals side by side; transverse ribs 8 welded between two adjacent triangular support plates 7; and two handles 9 (covered with a heat-insulating silicone layer to prevent high-temperature burns) welded to one side of the main baffle 3. One side of the transverse ribs 8 is welded and fixed to one side of the main baffle 3. The two handles 9 are located above the two transverse ribs 8 respectively. Two L-shaped fixing brackets 14 are located below the two transverse ribs 8 respectively. The bottom edge of the triangular support plates 7 contacts the upper surface of the electrolytic cell bottom shell 1. The three triangular support plates 7, together with the transverse ribs 8, form a triangular frame structure, which improves the deformation resistance of the main baffle 3 and can withstand the lateral pressure of the covering material without bending. The transverse ribs 8 connect the three triangular support plates 7 into a whole, distributing the stress load of the individual triangular support plates 7, avoiding excessive local stress that could lead to weld cracking, and at the same time enhancing the overall rigidity of the main baffle 3.

[0018] The lower side of the triangular support plate 7 is provided with anti-slip texture. The anti-slip texture increases the friction coefficient between the triangular support plate 7 and the bottom shell 1 of the electrolytic cell, which can resist the lateral displacement tendency of the main baffle 3 caused by the pressure of the covering material. Especially in the case that the gap may increase due to thermal expansion and contraction of the components in a high-temperature environment, it can still maintain the support stability and prevent the main baffle 3 from tilting or shifting.

[0019] Two spaced-apart T-shaped connecting slots 10 are provided on the side of the discharge port baffle 4 near the triangular support plate 7. The upper end of the T-shaped connecting slot 10 is connected to the upper side of the discharge port baffle 4, and its upper end extends through to the upper side of the discharge port baffle 4 to form an opening. Two spaced-apart T-shaped connecting blocks 11 are welded and fixed on the side of the partition plate 6 near the discharge port baffle 4. The T-shaped connecting blocks 11 slide with the T-shaped connecting slots 10. The opening design at the upper end of the T-shaped connecting slots 10 facilitates the installation and removal of the partition plate 6. After the covering material solidifies, the partition plate 6 can be pulled out to eliminate the connection resistance between the discharge port baffle 4 and the discharge port.

[0020] A folding handle 12 (covered with a heat-insulating silicone layer to prevent burns) is connected to the upper side of the partition plate 6 via a hinge structure. The folding handle 12 can rotate around the hinge axis. When folded, it fits against the top surface of the partition plate 6. When unfolded, it forms a U-shape for easy gripping. The hinge connection is made of high-temperature resistant metal to ensure connection strength in the high-temperature environment of the electrolytic cell. In the folded state, the folding handle 12 does not protrude from the surface of the partition plate 6, avoiding interference when the partition plate 6 is inserted into the T-shaped connection slot 10 of the discharge port baffle 4, and also preventing the folding handle 12 from accidentally snagging on other components and affecting the normal operation of the device.

[0021] An alumina ceramic bushing is embedded in the inner wall of the slot, with its edge flush with the slot port. The ceramic bushing can withstand the high-temperature environment during the operation of the aluminum electrolytic cell, preventing oxidation, deformation, or adhesion of the covering material to the inner wall of the slot due to long-term high-temperature baking, thus extending the service life of the main baffle 3. Secondly, the ceramic material has a smooth surface and strong wear resistance, which can reduce the frictional resistance when the main baffle 3 slides along the longitudinal partition 2, making the position adjustment of the main baffle 3 smoother and less labor-intensive.

[0022] Working process and principle: During operation, the main baffle 3 is first engaged with the two longitudinal partitions 2 on the bottom shell 1 of the electrolytic cell via the lower slot. The main baffle 3 is then pushed to slide along the longitudinal partitions 2 to a position 10 cm away from the outer side of the anode, so that the discharge port baffle 4 and the positioning plate 5 abut against the two sides of the bottom shell 1 of the electrolytic cell respectively. Then, the positioning bolts 15 on the L-shaped fixing bracket 14 are rotated to insert them into the corresponding positioning holes 13 of the longitudinal partitions 2, thus fixing the position of the main baffle 3. At this time, the three triangular support plates 7 with anti-slip textures contact the bottom shell 1 of the electrolytic cell to form a stable support, and the transverse ribs 8 further enhance the support strength.

[0023] When the covering material is added between the anode and the main baffle 3, the main baffle 3 prevents the covering material from rolling away from the anode, ensuring that the covering material always covers the anode. At the same time, the main baffle 3 provides support for the discharge port baffle 4, blocking the covering material at the discharge port and reducing the amount of covering material entering the discharge port. The large amount of heat generated during the electrolytic aluminum production will cause the alumina-crystal mixed covering material at the main baffle 3 and the discharge port baffle 4 to solidify into a fixed shape at high temperatures. When disassembly is required, the positioning bolt 15 is rotated in the opposite direction to disengage it from the positioning socket 13, and the main baffle 3 can be removed from the bottom shell 1 of the electrolytic cell by pulling the handle 9. The solidified covering material can still maintain its coverage of the anode. If the covering material has solidified due to heat, first hold the folding handle 12 to pull the partition plate 6 out from between the discharge port baffle 4 and the discharge port, then hold the handle 9 and move the main baffle 3 and the discharge port baffle 4 backward along the top of the electrolytic cell bottom shell 1 to separate them from the covering material. Finally, remove the main baffle 3 together with the discharge port baffle 4 from the electrolytic cell bottom shell 1.

[0024] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
