Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for aluminum electrolysis cell production, specifically a safety auxiliary tool for extinguishing the aluminum electrolysis quenching effect. Background Technology

[0002] The anode effect is a common phenomenon in aluminum electrolysis production, mainly caused by excessively low alumina concentration in the electrolyte. When the alumina concentration is too low, the anodic current density in the electrolyte increases, leading to the generation of a large amount of gas on the anode surface, thus forming the anode effect. Other factors that may cause the anode effect include excessively high impurity content in the electrolyte, excessively high electrolytic cell temperature, and uneven anode current distribution.

[0003] In aluminum electrolysis, the anode effect can adversely affect production, thus requiring measures to extinguish it. The principle of extinguishing the anode effect in aluminum electrolysis involves mitigating the anode effect and improving production efficiency by increasing the temperature of the molten aluminum, increasing the current density, adjusting the electrolyte composition, employing CO2 masking technology, and using flowing oxygen injection technology. Specific steps include: 1) Raising the anode: This is the first step in extinguishing the anode effect. Raising the anode temporarily stops the electrolysis process, reducing the contact area between the anode and the electrolyte, thereby lowering the current density; 2) Adding alumina: Simultaneously or after raising the anode, an appropriate amount of alumina is added to the electrolytic cell. Alumina decomposes during electrolysis to produce oxygen, which reacts with carbon particles on the anode surface, removing substances that hinder electrolysis; 3) Lowering the anode: After adding alumina for a period of time, the anode is gradually lowered to restore normal electrolysis. During this process, it is necessary to monitor various parameters of the electrolytic cell to ensure a stable transition; 4) Observing and confirming the extinguishing of the effect: After completing the above steps, it is necessary to closely observe changes in the voltage and other parameters of the electrolytic cell to confirm whether the anode effect has been successfully extinguished. If the effect is not completely extinguished, it may be necessary to repeat the above steps or take other measures.

[0004] In the above-mentioned operation steps for the quenching effect of aluminum electrolysis, the operator needs to insert the effect rod into the electrolysis cell through the observation port. During the process of inserting the effect rod into the electrolysis cell, the liquid in the cell will splash, which poses a risk of scalding the operator. Therefore, it is necessary to design a tool that can assist the operator in the operation to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a safety auxiliary tool for extinguishing the aluminum electrolysis effect. This tool has a reasonable structural design, is easy to operate and process, has low processing and manufacturing costs, can be used in conjunction with an effect rod, and assists in inserting the effect rod into the electrolytic cell for operation, making the operation safer and more reliable, and can protect the safety of operators.

[0006] This utility model relates to a safety auxiliary tool for extinguishing the aluminum electrolysis effect, comprising a fixed rod, with a sleeve fitted at one end of the fixed rod, and the fixed rod having a circular cross-section.

[0007] An effective rod is fitted inside the end of the sleeve.

[0008] The fixed rod allows the operator to hold it while performing the aluminum electrolysis quenching operation, and then insert the effect rod at its end into the aluminum electrolysis cell. This extends the distance between the operator and the observation port of the aluminum electrolysis cell. During the insertion of the effect rod, liquid splashing may occur inside the electrolysis cell. The fixed rod ensures a safe distance between the operator and the observation port, preventing burns from splashing liquid and guaranteeing operator safety. The sleeve securely connects the fixed rod and the effect rod, making the connection more reliable and stable, facilitating operation, saving installation time, and ensuring the smooth completion of the aluminum electrolysis quenching operation. This improves operational efficiency, saves time and manpower, further enhances operational safety, and fully guarantees operator safety.

[0009] The diameter of the effect rod is smaller than the diameter of the fixing rod.

[0010] The diameter of the effect rod gradually decreases from bottom to top, and the bottom end face of the effect rod is inserted into the sleeve.

[0011] The effect rod has a smaller diameter than the fixed rod. The smaller diameter of the effect rod and the larger diameter of the fixed rod make the operation of the effect rod, which is located at the front end, more flexible when it is inserted into the observation port of the aluminum electrolysis cell. The fixed rod is located at the rear end and is operated by hand, which makes the hand more secure and easier to apply force, making the whole operation more convenient and improving the efficiency of operation.

[0012] The end of the effect rod can extend into the aluminum electrolysis cell.

[0013] The effect rod is inserted into the observation port of the aluminum electrolysis cell to perform the aluminum electrolysis quenching effect operation, which makes the operation more flexible, environmentally adaptable and convenient, thus effectively supporting the efficient operation and safe production of the aluminum electrolysis production process.

[0014] Beneficial effects of the utility model:

[0015] 1) The fixed rod allows the operator to hold it while performing the aluminum electrolysis quenching operation, and then insert the effect rod at its end into the aluminum electrolysis cell.

The fixed rod ensures a safe distance between the operator and the observation port, preventing burns from splashing liquid and guaranteeing operator safety. The sleeve securely connects the fixed rod and the effect rod, making the connection more reliable and stable, facilitating operation, saving installation time, and ensuring the smooth completion of the aluminum electrolysis quenching operation. This improves operational efficiency, saves time and manpower, further enhances operational safety, and fully guarantees operator safety.

[0016] 2) The diameter of the effect rod is smaller than that of the fixed rod. The smaller diameter of the effect rod and the larger diameter of the fixed rod make the operation of the effect rod, which is located at the front end, more flexible when it is inserted into the observation port of the aluminum electrolysis cell. The fixed rod is located at the rear end and is operated by hand, which makes the hand more secure and easier to apply force, making the whole operation more convenient and improving the efficiency of operation.
