Description

Technical Field

[0001] The present invention relates to the technical field of aluminum electrolysis, and in particular to an anode data monitoring device and a monitoring method for an aluminum electrolysis cell. Background Art

[0002] With the development of science and technology, digitalization, intelligence, high efficiency and low energy consumption have become the development direction generally pursued by enterprises. The digitalization and intelligence of aluminum electrolytic cells have also become a hot topic in the industry. The digitalization of aluminum electrolytic cells requires more real-time data, but there is no mature technology in the industry for the anode-related data of aluminum electrolytic cells, which has become an important barrier on the road to the digitalization of aluminum electrolytic cells.

[0003] At present, the electrolytic aluminum production industry all uses pre-baked anode aluminum electrolytic cells. The anode carbon blocks of the pre-baked anode aluminum electrolytic cells are connected to the aluminum guide rods through the anode steel claw transition. The aluminum guide rods and the anode busbars of the electrolytic cell are crimped to form a current path. Each electrolytic cell has about 50 groups of anode groups that carry about 500kA of current. During the production process, it is hoped that each group of anodes will bear an average current, that is, the current distribution of the entire electrolytic cell is as uniform as possible. However, due to the differences in the consumption rate of each group of anodes and other reasons, the current distribution of the anodes is often uneven, also known as bias current. When there is a significant bias current, it will affect the stability of the electrolytic cell, thereby reducing the current efficiency of the electrolytic cell and increasing the power consumption. In serious cases, safety accidents may also occur. Therefore, when bias current occurs, it is necessary to make timely adjustments.

[0004] At present, this kind of adjustment work in the industry requires manual measurement of the distributed voltage drop on each group of anode guide rods with a voltmeter to compare and determine which group of anodes has bias current. Since each electrolytic cell has about 50 groups of anode groups, the step-by-step measurement in an environment with an ambient temperature of up to about 80°C is not only labor-intensive but also extremely inefficient. Therefore, in normal production, there is always a phenomenon that the safe and stable operation of the electrolytic cell is affected due to the untimely detection of bias current. This is one of the reasons for the low current efficiency of the overall electrolytic aluminum production industry.

[0005] In addition, the anode guide rod and the anode busbar are connected by crimping, and there is a crimping voltage drop. In the production process, the crimping caused by the rise and fall of the anode is loose, and the crimping surface treatment is not clean, which will cause excessive crimping voltage drop and energy loss. Moreover, the increase and change of the crimping voltage drop caused by the rise and fall of the anode is dynamic, and it also needs to be discovered and processed in time. The current industry's measurement method for this part of the voltage drop is the same as measuring the guide rod crimping voltage drop, which requires manual measurement one by one through a voltmeter. There are also problems with poor working environment and low efficiency. Due to untimely measurement, energy loss is caused. There have also been serious accidents in the industry where the system was shut down due to the failure to timely discover that the anode crimping voltage drop was too high.

[0006] Real-time and accurate measurement and mastering of the anode data of aluminum electrolytic cells (distribution of voltage drop of the guide rod, crimping voltage drop between the anode guide rod and the busbar) parameters are of great significance for timely understanding the operation status of the electrolytic cell, optimizing the production process, improving current efficiency, reducing energy consumption and ensuring production safety. It is also inevitable data for the construction of digital electrolytic cells.

[0007] At the same time, the traditional manual measurement process is easily interfered by various objective factors, such as the uniformity of the measurement position, the standardization of the measurement method, etc., which directly leads to low reference of the data results and difficulty in accurately reflecting the actual production situation. After the anode data real-time monitoring device is installed, the position is fixed, the collected data is more accurate, and has a stronger analysis and comparison function.

[0008] Existing detection devices, such as the anode current distribution detection device disclosed in patent announcement number CN213457097U, have a spring on the bridge plate, which is connected to the collection plate, and a spring plunger is arranged on the collection plate, which contacts the anode guide rod to collect voltage. It has the following problems: (i) The spring plunger and the guide rod are in sliding contact. Since the surface of the guide rod is uneven, the sliding contact cannot ensure that the spring plunger and the guide rod are in close contact, resulting in a large error in the collected data; (ii) It can only collect the voltage of the anode guide rod, and cannot collect the voltage between the busbars at the same time, which limits its scope of use. Summary of the invention

[0013] Preferably, a nylon sleeve is provided between the first measuring rod and the sleeve, and between the second measuring rod and the sleeve.

[0014] Preferably, an ash outlet is provided on the side of the corner wall.

[0015] Preferably, the ends of the first measuring rod and the second measuring rod are both provided with a bayonet for enveloping the top ball.

[0019] The present invention also provides a method for monitoring data of an anode of an aluminum electrolysis cell, which is performed using the above-mentioned device for monitoring data of an anode of an aluminum electrolysis cell, and comprises: Place the measuring point A on the first measuring rod and the measuring point B on the second measuring rod at different positions on the anode guide rod, and install the measuring wire on the measuring table; collect the anode distribution voltage V1 between AB; install the wire at point C of the anode busbar; collect the crimping voltage V2 between AC.

[0020] Compared with the related art, the present invention has the following beneficial effects: 1. The anode data monitoring device for aluminum electrolytic cell is provided with a top ball at the end of the measuring rod. The top ball is in rolling contact with the anode guide rod. Compared with sliding contact, it can more effectively adapt to the precise fitting measurement when the surface of the anode guide rod is rough or uneven, and does not damage the measuring rod, reduces the force on the measuring rod in the up and down directions, and ensures the stability of the measurement data; Second, the aluminum electrolytic cell anode data monitoring device is designed with a first measuring rod and a second measuring rod, which can simultaneously collect two important data, namely, the voltage drop of the anode guide rod distribution and the voltage drop of the crimping between the anode guide rod and the anode busbar, to provide important data support for the construction of digital electrolytic cells and the comprehensive analysis of the operating status of aluminum electrolytic cells; 3. The anode data monitoring device for the aluminum electrolytic cell is provided with a top bead at the end of the measuring rod, and the top bead is abutted by a sleeve having a first spring. When working, the sleeve can scrape off the oxide layer on the surface of the top bead, so that the top bead and the anode guide rod always maintain good conductive contact, ensuring the continuous and effective measurement, and solving the problem that the device cannot continue to be used accurately due to the oxide layer generated on the contact after long-term use; Fourth, the third rod and the fourth rod of the second measuring rod are designed to be structures with acute angles to each other, that is, the third rod is tilted upward relative to the fourth rod. During the up and down displacement of the top bead, vibration will be generated due to the action of the first spring, so that the oxide layer scraped off by the sleeve is discharged from the ash outlet under the action of the vibration and the tilted structure, achieving the effect of maintaining good contact without maintenance; 5. The present invention only needs to install one contact point C on the anode busbar to cooperate with the measuring point A and the measuring point B, and simultaneously test the two data of the anode distribution voltage and the crimping voltage; only three wires are needed to measure the two data, which is one less than the four wires required for the two voltage data in the general measurement scheme. Generally, there are about 300 electrolytic cells in one electrolytic cell, and one electrolytic cell generally has 50 anode guide rod groups. If one wire is reduced for each anode guide rod, 15,000 wires can be reduced in one series, which is more convenient to use; 6. When the aluminum electrolytic cell anode data monitoring device is not in use, the measuring rod can be pulled to lock at the locking position without disassembly; and the measuring device is not affected by the production actions and various operating actions of the aluminum electrolytic cell during use, and the device does not need to be disassembled for all operations on the electrolytic cell. It is easy to use and can ensure that the device is fully put into use in actual production; it can replace the problems of high labor intensity, low work efficiency, and large data errors in manual measurement; 7. The measuring rod is connected to the housing through the second spring. Under the action of the second spring, sufficient pressure can be ensured to ensure good contact between the top ball and the anode guide rod, and the force on the measuring rod in the up and down directions can be reduced; 8. The measuring rod is connected to the housing through the second spring. When the anode group is replaced in the aluminum electrolytic cell, the measuring rod is pulled to be clamped on the lock. The pulling force is greater than the pulling force of the second spring. The operation is simple and convenient. 9. The anode data monitoring device of the aluminum electrolytic cell is made of anti-magnetic stainless steel, which can prevent the direct influence of the strong magnetic environment of the aluminum electrolysis workshop and ensure the smooth movement of all parts; the top ball is made of copper, which effectively ensures the conductive efficiency and reduces the measurement error; a nylon sleeve is used between the measuring rod and the sleeve to effectively ensure the insulation between the measuring rod and the sleeve.

DETAILED DESCRIPTION

[0023] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict. For the convenience of description, if the words "upper", "lower", "left" and "right" appear in the following, they only indicate that the upper, lower, left and right directions are consistent with the drawings themselves, and do not limit the structure.

[0024] like Figure 1 , Figure 2As shown, an aluminum electrolytic cell anode data monitoring device provided in this embodiment includes a shell 1, a first measuring rod 21, a second measuring rod 22, a first spring 3, a nylon sleeve 4, a top ball 5, a second spring 6, a locking piece 7 and a sleeve 8.

[0025] The housing 1 is made of stainless steel and has an inner cavity 11 therein. The inner cavity 11 penetrates through both sides of the housing 1 in the first direction to form a through hole 12, and the inner cavity 11 does not penetrate in the second direction to form a side wall. The first direction and the second direction are perpendicular to each other on the same top projection plane. A second spring 6 is installed on one of the side walls near the measuring point A and the measuring point B.

[0026] The first measuring rod 21 includes a first rod 211, a second rod 212 and a third rod 213. One end of the first rod 211 is connected to one end of the second rod 212 and is at right angles to each other on the same top projection plane. The other end of the first rod 211 is hinged to the housing 1, and the other end of the second rod 212 is connected to the third rod 213 through a nylon sleeve 4. The end of the third rod 213 is installed with the top ball 5 to form a measuring point A. The third rod 213 is a conductive guide rod and is insulated from the second rod 212 through the nylon sleeve 4. A corner wall 23 is formed at the corner of the second rod 212 and the first rod 211.

[0027] The second measuring rod 22 includes a fourth rod 221, a fifth rod 222, a sixth rod 223 and a seventh rod 224. One end of the seventh rod 224 is hinged to the housing 1, and the seventh rod 224 is located below the first rod 221 and the two are arranged in parallel. The other end of the seventh rod 224 is vertically connected to one end of the fourth rod 221. The other end of the fourth rod 221 is connected to one end of the fifth rod 222 and forms an acute angle with each other on the same front projection plane. The other end of the fifth rod 222 is connected to the sixth rod 223 through a nylon sleeve 4, and the top ball 5 is installed at the end of the sixth rod 223 to form a measuring point B. The corner of the fourth rod 221 and the fifth rod 222 forms a corner wall 23.

[0028] The top ball 5 rotates with full freedom in the respective measuring rods. To prevent the top ball 5 from falling out, a bayonet 24 for enveloping the top ball 5 is provided at the ends of the third rod 213 and the sixth rod 223, respectively. The top ball 5 is made of conductive copper. Figure 2 As shown, the second rod 212 and the third rod 213 are on the same axis, the fifth rod 222 and the sixth rod 223 are on the same axis, the second rod 212 and the third rod 213 are parallel to the fifth rod 222 and the sixth rod 223, and are all inclined upward. The first measuring rod 21 and the second measuring rod 22 are both provided with measuring wires, and the measuring wires are connected to the top ball 5.

[0029] like Figure 3As shown, the first rod 211 and the fourth rod 221 are hinged to the same position of the housing 1 through a pin. There are two second springs 6, one end of each of which is connected to the side wall of the housing 1 forming the inner cavity 11, the other end of one second spring 6 is connected to the first rod 211, and the other end of the other second spring 6 is connected to the fourth rod 221.

[0030] The upper and lower side walls of the inner cavity 11 of the housing 1 are both provided with locking members 7, and the locking members 7 are away from the measuring point A and the measuring point B. A hemispherical buckle is provided on the side where the upper and lower locking members 7 are close to each other. Figure 1 After pulling rightward until crossing the hemispherical buckle, the buckle abuts against the first measuring rod 21 and the second measuring rod 22 to achieve locking, so that the measuring point A and the measuring point B are separated from the anode guide rod 101 (as shown in FIG. Figure 5 As shown), to facilitate the replacement of the anode guide rod 101 of the aluminum electrolytic cell.

[0031] like Figure 4 The figure shows the internal structure of the sixth rod 223 and the fifth rod 222 in the second measuring rod 22. The second rod 212 and the third rod 213 in the first measuring rod 21 are the same as those of the second measuring rod 22. The sleeve 8 is sleeved in the second rod 212 and the third rod 213. A first spring 3 is arranged between the sleeve 8 and the corner wall 23. The sleeve 8 is abutted against the top ball 5 by the first spring 3, so that the oxide layer on the top ball 5 can be scraped off through the side wall of the sleeve 8 during the rotation of the top ball 5. The sleeve 8 passes through the nylon sleeve 4, and the radial position of the sleeve 8 in the measuring rod is limited by the nylon sleeve 4. An ash outlet 9 is arranged at the bottom of the second rod 212, and the ash outlet 9 is arranged close to the corner wall 23. The scraped oxide layer falls out of the sleeve 8 and the third rod 213 from the ash outlet 9. The sleeve 8 is made of copper.

[0032] The structures and operating principles of the internal mounting sleeve 8 and the first spring 3 of the sixth rod 223 and the fifth rod 222 in the second measuring rod 22 are the same as those of the first measuring rod 21 .

[0033] The rolling top ball 5 provided in the present invention can better adapt to the uneven surface of the anode guide rod 101, adhere closely, and ensure the measurement accuracy.

[0034] By adding a sleeve 8 in contact with the top bead 5, the oxide layer on the top bead 5 can be automatically cleaned to ensure the long-term use effect. The specific cleaning process is: when the top bead 5 rolls, the sleeve 8 scrapes the surface of the top bead 5 under the pressure of the first spring 3, which can remove the oxide layer on the surface of the top bead 5 caused by long-term use, ensuring that the top bead 5 and the anode guide rod 101 are in good contact when the equipment is used for a long time, thereby ensuring the long-term stable use of the monitoring device.

[0035] After the installation, the present invention is easy to operate, and the oxide layer on the top bead 5 is automatically cleaned to ensure the effect of long-term use. The voltage drop of the anode guide rod 101 can be monitored in real time, and the problems of uneven current distribution of the anode guide rod 101 and abnormal operation of the anode can be discovered in time, so that corresponding measures can be taken for adjustment and control, thereby reducing power loss, promoting safe and stable operation of the electrolytic cell, and being easy to promote.

[0036] like Figure 5 , Figure 7 As shown, a method for monitoring anode data of an aluminum electrolysis cell of the present invention is performed using the above-mentioned anode data monitoring device of an aluminum electrolysis cell, and comprises the following steps: S1, install the housing 1 at a suitable position on the bottom surface of the anode busbar 102 by means of bolts; S2, the measuring point A on the first measuring rod 21 and the measuring point B on the second measuring rod 22 are respectively pressed against different positions on the anode guide rod 101 through the second spring 6. The high temperature resistant wires are respectively inserted from the third rod 213 and the sixth rod 223 into the top beads 5 at their respective positions and connected. The two wires connected to the top beads 5 of the measuring points A and B are used to measure the distributed voltage, and then the measuring wires are installed on the measuring meter to collect the anode distributed voltage V1 between AB.

[0037] S3, a wire is installed at point C of the anode busbar 102 using a screw 10, and the voltage between point C and point A is measured, thereby collecting the crimping voltage V2 between AC.

[0038] like Figure 6 As shown, after the device is installed, four pressure measuring lines are connected from the device and connected to the rear ends of three measuring contacts respectively, and the other side is connected to the MV voltage measurement module. The measurement module collects data and converts it into MODBUSTCP protocol, which is connected to the host computer through the data bus.

[0039] The host computer establishes a data configuration interface, generates real-time data display, records data history, generates historical data curves synchronously, and sets data over-limit warning function to remind technicians to handle abnormalities. The DTU data acquisition module uploads data directly to the cloud server, making it convenient for operators to view and receive alarm push in real time through mobile phones.

[0040] When the anode guide rod 101 is displaced relative to the anode busbar 102, the top ball 5 rolls in the displacement direction, which can reduce the shear force generated in the up and down directions of the measuring rod and protect the measuring rod from damage. This allows the electrolytic cell to be operated without any operation on the collection device when adjusting the pole or lifting the busbar, thereby reducing the workload of employees and the difficulty of operation.

[0041] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
