Description

Technical Field

[0001] The utility model relates to the technical field of aluminum electrolysis cells, and in particular to a device for quickly forming a furnace ridge of an aluminum electrolysis cell. Background Art

[0002] The formation of the furnace side of the electrolytic cell mainly utilizes the temperature difference between the inside and outside of the side of the electrolytic cell. If the external temperature is lower, the furnace side will be formed faster, better and more regular. The furnace side is the core of the safe and efficient operation of the electrolytic cell. High-quality furnace side is the guarantee of a regular furnace. It can not only reduce leakage on the side of the electrolytic cell and improve current efficiency; but also high-quality furnace side has the function of heat preservation, reducing side heat dissipation to ensure heat intake of the electrolytic cell and reduce power consumption.

[0003] Newly started electrolytic cells need to quickly form a high-molecular-weight rib to ensure safe and efficient operation after the cell enters the normal period. Currently, newly started electrolytic cells form ribs very slowly, with 90% of them failing to reach the standard rib thickness during the high-molecular-weight electrolyte period. Furthermore, electrolytic cells cannot operate for long periods of time at high ribs. If the ribs cannot be formed and reach the standard thickness during the high-molecular-weight electrolyte period, they are prone to melting or damage after the cell enters the normal period, which is detrimental to the safe, stable, efficient, and long-life operation of the cell.

[0026] Example

[0027] like Figure 1-4 As shown, this embodiment provides a device for quickly forming a furnace wall of an aluminum electrolytic cell, including a baffle 1, and a plurality of support plates 2 are provided on one side of the baffle 1, each of the support plates 2 is perpendicular to the baffle 1, and the height of the support plate 2 is less than the height of the baffle 1, and the support plate 2 includes a first support plate 21 and a second support plate 22, and the second support plate 22 is slidably installed in the first support plate 21.

[0028] The baffle 1 and support plate 2 work together to effectively and rapidly form a high-molecular-weight furnace rib (the furnace rib of an electrolytic cell 10 days after startup is 8-12 cm). This can be achieved more than two days earlier than without this device, reducing the startup voltage to below 4V and significantly reducing power consumption. The baffle is standard and the same size as the heat dissipation belt, forming a relatively uniform and regular furnace rib. It can block the anode material, prevent anode oxidation, and ensure the upper part of the anode is kept warm. The vertical arrangement of baffle 1 and support plate 2 fully exposes the electrolytic cell's heat dissipation belt, ensuring that the anode is not oxidized while the heat dissipation belt is fully dissipated, enabling rapid cooling. The first support plate 21 and the second support plate 22 are slidably connected, allowing the length of support plate 2 to be adjusted, thereby forming furnace ribs of varying thicknesses according to the needs of the electrolytic cell. The first support plate 21 can be welded to the baffle 1.

[0029] The height of baffle 1 is designed to minimize interference with plugging and pole shaping. Its length is designed to prevent interference with pouring when used at both ends of a corner pole. The length and width of support plate 2 are designed to minimize interference with the switch slot cover. Baffle 1 is made of standard steel, eliminating the need for higher-quality steel and reducing costs. Specifically, baffle 1 is 1500mm long and 240mm high, support plate 2 is 260mm long, and the distance between adjacent support plates is 750mm.

[0030] Furthermore, there are three support plates 2, with adjacent support plates 2 spaced uniformly apart. Two support plates 2 are located at either end of the baffle 1, and another support plate 2 is located in the middle of the baffle 1. When connected to the baffle 1, the three support plates 2 form an E-shape. This E-shaped structure increases the stability of the device. The spacing helps form a uniform furnace wall.

[0031] Furthermore, a slide groove 211 is defined within the first support plate 21, and the second support plate 22 is slidably mounted within the slide groove 211. A push plate 3 is provided on the side of the baffle plate 1 away from the support plate 2. A push rod 4 is mounted on the push plate 3, which passes through the baffle plate 1 and the first support plate 21 and connects to the second support plate 22. During use, the push plate 3 is pushed, which drives the push rod 4 to move, and the push rod 4 drives the second support plate 22 to move, allowing the second support plate 22 to extend beyond the first support plate 21, thereby increasing the length of the support plate 2 and facilitating the formation of furnace sides of varying thicknesses.

[0032] Furthermore, the push rod 4 is provided with a plurality of first limiting holes 5, and the baffle plate 1 is provided with a plurality of second limiting holes 6, and the first limiting holes 5 and the second limiting holes 6 are connected by limiting posts 7. When the push plate 3, the push rod 4, and the second support plate 22 move, the first limiting holes 5 on the push rod 4 and the second limiting holes 6 on the baffle plate 1 are connected. Specifically, when the axis of a first limiting hole 5 of the push rod 4 and a second limiting hole 6 on the baffle plate 1 are aligned, the limiting post 7 is inserted into the second limiting hole 6, enters the first limiting hole 5, and then extends out of the first limiting hole 5, thereby fixing the push rod 4 and the second support plate 22, thereby preventing the second support plate 22 from moving during the process of forming the furnace side.

[0033] Furthermore, a retaining plate 8 is provided on top of the baffle 1 and is rotatably connected to the baffle 1. During the process of forming the furnace side, the retaining plate 8 is rotated as needed, so that the retaining plate 8 is perpendicular to the baffle 1 and directly above the support plate 2, thereby protecting the furnace side. When not in use, the retaining plate 8 can be rotated so that it stands upright on top of the baffle 1.

[0034] Furthermore, mounting seats 9 are provided at both ends of the top of the baffle 1, and connecting seats 10 are provided at both ends of the baffle plate 8. The two connecting seats 10 are respectively connected to the mounting seats 9 through rotating shafts.

[0035] When using: When finishing the edge of the newly started cell, clean the edge of the anode of the electrolytic cell, install the device, make the baffle 1 and the electrolytic cell rib plate on the same horizontal plane, align it with the anode edge horizontally, and make it stable and firm to block the material and leak out of the heat dissipation zone.

[0036] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
