Description

Technical Field

[0001] This utility model belongs to the field of aluminum electrolytic cell anode measurement technology, specifically relating to an aluminum electrolytic cell anode measurement and positioning device. Background Technology

[0002] The prebaked anode of the aluminum electrolysis cell consists of multiple carbon anodes, such as Figure 1 As shown, each anode 00 consists of an anode carbon block 01 with a thickness of approximately 60 cm, a steel claw 02, and an anode guide rod 03. During the electrolytic aluminum production process, the anode carbon block is continuously consumed, and its thickness decreases accordingly. When it is consumed to a certain extent, a new anode replaces the residual anode to ensure continuous aluminum electrolysis production. During electrode replacement, to avoid localized flow deviation in the electrolytic cell, the bottom of the new anode and the residual anode must be at the same height in the electrolytic cell, thus ensuring that the bottom of the entire prebaked anode is on a single plane after electrode replacement. Therefore, operators need to measure the overall height of the residual anode and determine the installation position of the new anode based on the measured overall height of the residual anode. In addition, the analysis of electrolytic cell production data also needs to refer to the thickness of the remaining anode carbon block in the residual anode. For example, by measuring the thickness of the residual anode at different locations in the electrolytic cell, the regularity of the electrolytic cell furnace can be analyzed.

[0003] The current method of measuring residual electrodes and locating new electrodes mainly relies on manual measurement and marking using a measuring tape, which is inefficient, prone to human error when drawing lines, and results in inaccurate positioning of new electrodes, affecting the stable operation of the electrolytic cell. In addition, since the temperature of residual electrodes can reach as high as 900℃, there are certain safety hazards in the measurement process. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides an aluminum electrolytic cell anode measurement and positioning device, which enables precise measurement of residual electrodes and automatic marking of the installation position of new electrodes, thereby improving production efficiency, reducing human error, and eliminating safety hazards.

[0005] The aluminum electrolytic cell anode measurement and positioning device provided by this utility model includes a bracket, a stop block, a first driving component, a first sensor, a second driving component, a first measurement component, an identification component, and a positioning identification component;

[0006] The first driving member and the second driving member are mounted on the bracket;

[0007] The movable end of the first driving component is connected to the abutment block, and it performs a vertical lifting and lowering motion;

[0008] The block is set horizontally;

[0009] The first sensor is disposed on the abutment block. When the first sensor senses the bottom of the anode, the first driving member stops driving.

[0010] The movable end of the second driving component is connected to the first measuring component, the identification component, and the positioning identification component, and performs vertical lifting and lowering motion;

[0011] The first measuring component is used to obtain the anode mark height a, the mark recognition component is used to recognize the mark on the anode guide rod, and the positioning mark component is used to make a mark on the anode guide rod; when the mark recognition component recognizes the mark, or when the first measuring component rises to the anode mark height a, the second driving component stops driving.

[0012] The working process of the aluminum electrolytic cell anode measurement and positioning device provided by this utility model includes residual electrode measurement and new electrode marking.

[0013] Residual electrode measurement: The residual electrode is placed above the abutment block. The first driving unit drives the abutment block to rise vertically. When the first sensor on the abutment block senses the bottom of the anode, the first driving unit stops driving and the second driving unit is activated. The identification component and the first measuring component rise vertically accordingly. When the identification component identifies the mark on the anode guide rod of the residual electrode, the second driving unit stops driving and the first measuring component measures the anode mark height 'a' of the residual electrode.

[0014] New electrode marking: Reset the first and second drive components, remove the residual electrode, place the new electrode above the stop block, the first drive component drives the stop block to rise vertically, when the first sensor on the stop block senses the bottom of the anode, the first drive component stops driving, the second drive component is started, the first measuring component and the positioning mark component rise vertically accordingly, when the first measuring component rises to the recorded anode mark height 'a', the second drive component stops driving, and the positioning mark component marks the anode guide rod of the new electrode.

[0018] The second measuring component is used to obtain the distance b from the marker to the steel claw.

[0019] The aforementioned aluminum electrolytic cell anode measurement and positioning device can be used to obtain the thickness h of the remaining anode carbon block on the residual electrode. The working process is as follows: The residual electrode is placed above the abutment block. The first driving component drives the abutment block to rise vertically. When the first sensor on the abutment block senses the bottom of the anode, the first driving component stops driving and starts the second driving component. The marking and identification component and the first measuring component rise vertically accordingly. When the marking and identification component identifies the marking on the anode guide rod of the residual electrode, the second driving component stops driving, and the first measuring component measures the height a of the anode marking on the residual electrode. The third driving component drives the second sensor and the second measuring component to extend horizontally. When the second sensor on the movable end of the third driving component senses the anode guide rod, the third driving component stops driving, and the second measuring component measures the distance b from the marking to the steel claw. The height between the steel claw and the upper surface of the anode carbon block is a fixed value c. The thickness h of the remaining anode carbon block on the residual electrode can be calculated using the formula h = abc, which is used for electrolytic cell production data analysis.
