Description
Technical Field
[0001] This application relates to the field of intelligent temperature measuring robots for electrolytic aluminum production, and more particularly to an intelligent temperature measuring robot for electrolytic aluminum production. Background Technology
[0002] Electrolytic aluminum is the core process for industrial production of metallic aluminum. High-purity primary aluminum is obtained by electrolyzing molten alumina. Aluminum and aluminum alloys have the characteristics of being lightweight, corrosion resistant, and having excellent electrical and thermal conductivity, and are widely used in construction, transportation, packaging, and power industries.
[0003] In the electrolytic aluminum production process, high-purity alumina is first extracted from bauxite. Then, the alumina is mixed with cryolite as a flux in a certain proportion and fed into an electrolytic cell at the production site and heated to a molten state. Subsequently, direct current is passed into the electrolytic cell. Under the action of the electric field, the molten alumina undergoes an electrolytic reaction, decomposing into aluminum ions and oxygen ions. The aluminum ions gain electrons at the cathode and are reduced to liquid aluminum, which is deposited at the bottom of the cell. The oxygen ions lose electrons at the anode and react with the carbon electrode to generate carbon dioxide. Finally, the liquid primary aluminum at the bottom of the cell is periodically extracted and then refined to form the finished product.
[0004] In the electrolytic aluminum production process, it is necessary to monitor the temperature inside the electrolytic cells at the production site. The purpose is that when the temperature inside the electrolytic cell is too high, it will cause the carbon electrode to be consumed, increasing energy consumption. When the temperature is too low, it will lead to an increase in electrolyte viscosity, hindering the migration of aluminum ions, and even causing the substances inside the cell to solidify. Therefore, in the electrolytic aluminum production process, it is necessary to frequently monitor the operating status of the electrolytic cells, and the temperature at both ends of the electrolytic cell is also an important parameter to be monitored. However, due to the small space and high temperature at the production site, it is not convenient for staff to flexibly monitor the temperature inside many electrolytic cells, and there is room for improvement. Utility Model Content
[0005] The purpose of this utility model is to improve the convenience of detecting the temperature inside the electrolytic cell during the electrolytic aluminum production process. This application provides an intelligent temperature measuring robot for electrolytic aluminum production.
[0006] To achieve the above objectives, this application provides an intelligent temperature measuring robot for electrolytic aluminum production, which adopts the following technical solution:
[0007] An intelligent temperature measuring robot for electrolytic aluminum production includes a guide rail deployed on the production site and a control box slidably mounted on the guide rail. The control box is equipped with a drive component and a detection component. The drive component is used to drive the control box to reciprocate along the length of the guide rail. The detection component includes an infrared temperature detection sensor, a positioning component, and a controller. The infrared temperature detection sensor, the positioning component, and the controller are electrically connected. The positioning component includes a position detector and a slot number detector.
[0008] Preferably, the control box is provided with a connecting frame, on which a drive wheel and a driven wheel assembly are rotatably supported. The guide rail is located between the drive wheel and the driven wheel assembly. When the drive assembly drives the drive wheel to rotate along the guide rail, the driven wheel assembly follows the drive wheel and rotates in the same direction along the guide rail.
[0009] Preferably, the control box has guide wheels rotatably mounted on its side walls along the width direction.
[0010] Preferably, a fixing plate is provided on the guide rail, and a waist-shaped groove is formed on the fixing plate.
[0011] Preferably, the detection component further includes an alarm, which is electrically connected to the controller.
[0012] Preferably, the control box is equipped with a power supply module.
[0013] Preferably, the control box is provided with an insulating tube, and the infrared temperature detection sensor and the alarm are located at the end of the insulating tube away from the end that abuts against the control box.
[0014] Compared with the prior art, this utility model provides an intelligent temperature measuring robot for electrolytic aluminum production, which has the following beneficial effects:
[0015] 1. The control box is driven to reciprocate along the guide rail by the drive device. The position of the control box is controlled by the position detector and the cell number detector detects the cell number of the electrolytic cell in which the control box is located. With the cooperation of the position detector and the cell number detector, the control box can be stably stopped at the electrolytic cell to be measured. The temperature of the current electrolytic cell is detected by the temperature detection sensor and the result is sent to the controller. The controller determines whether the temperature of the current electrolytic cell is normal. This cycle can realize the purpose of automatic detection of the temperature in electrolytic cells of different cell numbers. It plays a positive guiding role in improving the convenience of temperature detection in electrolytic cells during the electrolytic aluminum production process.
[0016] 2. By using the guiding action of the guide wheels, the control box is prevented from being in a non-contact state with the wall of the production site when it moves along the guide rail through the cooperation of the drive wheel and the driven wheel set. This reduces the probability of the control box being scratched or worn due to direct contact between the surface of the control box and the wall of the production site.
[0017] 3. The control box is equipped with a power supply module, which can supply power to the drive components and detection components without the need for an external power supply to the control box. This provides high flexibility and avoids the problem of wire tangling when the control box reciprocates along the guide rail. Attached Figure Description

[0023] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0024] This application discloses an intelligent temperature measuring robot for electrolytic aluminum production. (Refer to...) Figure 1 and Figure 2A smart temperature measuring robot for electrolytic aluminum production includes a guide rail 1 deployed on the production site and a control box 2 slidably mounted on the guide rail 1. The control box 2 is equipped with a drive component 3 and a detection component 4. The detection component 4 includes an infrared temperature detection sensor 41, a positioning component 42, and a controller 43. The infrared temperature detection sensor 41, the positioning component 42, and the controller 43 are electrically connected. The positioning component 42 includes a position detector 421 and a slot number detector 422.
[0025] Specifically, the length and shape of the guide rail 1 can be changed according to the number of electrolytic cells placed in the production site or the layout design requirements of the production site, and are not limited here.
[0026] The guide rail 1 is equipped with a fixing plate 61, which has a waist-shaped groove 611. Several fixing plates 61 are provided, and they can be fixedly connected to the guide rail 1 by bolts or welding. The fixing plates 61 are evenly distributed along the length of the guide rail 1; the specific number of fixing plates 61 is not limited here. The waist-shaped groove 611 is formed through the fixing plate 61 along its thickness direction. The guide rail 1 can be fixed to the installation surface (e.g., wall, equipment rack) on the production site using bolts through the waist-shaped groove 611. The installation surface has pre-cut mounting positions for the guide rail 1. Simultaneously, the waist-shaped groove 611 allows adjustment of the installation angle between the guide rail 1 and the installation surface, as well as the installation position of the guide rail 1 relative to the mounting position. This reduces the likelihood of the guide rail 1 being unable to be installed due to positional deviations between the guide rail 1 and the mounting position, resulting in high adaptability.
[0027] Meanwhile, guide wheels 6 are rotatably mounted on the side walls of the control box 2 along the width direction. The rotation direction of the guide wheels 6 is the same as the direction of movement of the control box 2 along the length direction of the guide rail 1. When the control box 2 moves along the guide rail 1, the guide wheels 6 abut against the mounting surface. Through the guiding effect of the guide wheels 6, the control box 2 is prevented from being in a non-contact state with the wall of the production site when it moves along the guide rail 1 through the cooperation of the drive wheel 51 and the driven wheel group 52. This reduces the probability of scratches or wear on the control box 2 caused by direct contact between the surface of the control box 2 and the wall of the production site.
[0028] Correspondingly, refer to Figure 1 and Figure 2 The control box 2 is provided with a connecting frame 5. The connecting frame 5 is hollow inside. The connecting frame 5 rotatably supports a drive wheel 51, a clamping wheel 53, and a driven wheel set 52. The driven wheel set 52 includes a first driven wheel 521 and a second driven wheel 522.
[0029] Among them, the clamping wheel 53 is located on the connecting frame 5 below the drive wheel 51, and the first driven wheel 521 and the second driven wheel 522 are rotatably supported on the connecting frame 5 at the end away from the drive wheel 51 and the clamping wheel 53, with the first driven wheel 521 located below the second driven wheel 522.
[0030] The key point is that the drive wheel 51 and the first driven wheel 521 are in the same plane, and the clamping wheel 53 and the second driven wheel 522 are in the same plane. Therefore, the gap formed between the drive wheel 51 and the clamping wheel 53, as well as the gap formed between the first driven wheel 521 and the second driven wheel 522, and the width tolerance of the guide rail 1 are in a transitional fit, so that the guide rail 1 can move smoothly between the drive wheel 51, the clamping wheel 53, the first driven wheel 521 and the second driven wheel 522.
[0031] Furthermore, the guide rail 1 is provided with several limit blocks 11 along its length. When the control box 2 moves along the guide rail 1, the position detector 421 is installed on the side wall of the connecting frame 5 along its width, and the detection end of the position detector 421 faces the guide rail 1. The position detector 421 detects the limit block 11. When the position detector 421 detects the limit block 11, it sends a detection signal to the controller 43. The controller 43 will issue a control command to the drive component 3 to stop working, thereby reducing the probability that the detection end of the infrared temperature detection sensor 41 will deviate from the electrolytic cell to be detected due to the drive component 3 driving the control box 2 to move too far along the guide rail 1, resulting in the inability to accurately measure the temperature of the electrolytic cell to be measured.
[0032] Meanwhile, the cell number detector 422 is located on the connecting frame 5 below the position detector 421. The cell number detector 422 detects the cell number of the electrolytic cell at the location of the controller 43 to determine the cell number information of the current electrolytic cell. After the cell number detector 422 has completed the detection of the cell number of the electrolytic cell at the location of the control box 2, it sends the detection signal to the controller 43 so that the controller 43 can match the temperature detection information of the current electrolytic cell by the infrared temperature detection sensor 41 with the cell number of the current electrolytic cell. This reduces the probability of data errors caused by the mismatch between the cell number information of the electrolytic cell received by the controller 43 and the electrolytic cell information that has passed temperature detection, and improves the accuracy of the detection results.
[0033] Furthermore, refer to Figure 2 and Figure 3The drive assembly 3 includes a drive motor 31, a commutator 32, a first synchronous pulley 33, a synchronous belt 34, and a second synchronous pulley. A mounting bracket 21 is installed inside the control box 2. The drive motor 31 and the commutator 32 are mounted on the mounting bracket 21. The output shaft of the drive motor 31 is connected to the input end of the commutator 32. The first synchronous pulley 33 is coaxially fixed with the output shaft of the commutator 32. At the same time, the second synchronous pulley is coaxially fixed with the drive wheel 51, and the synchronous belt 34 is sleeved on the first synchronous pulley 33 and the second synchronous pulley.
[0034] It should be noted that the commutator 32 is used to change the torque output by the output shaft of the drive motor 31 and the rotation direction of the output shaft, so as to increase the torque output by the output shaft of the drive motor 31. It is a conventional drive component, and its specific composition and working principle will not be described in detail here.
[0035] Therefore, when the drive motor 31 cooperates with the commutator 32 to drive the first synchronous pulley 33, which is coaxially fixed with the output shaft of the commutator 32, to rotate, the first synchronous pulley 33 and the second synchronous pulley are fitted with synchronous belts 34, which in turn drive the second synchronous pulley to drive the drive wheel 51 to rotate along the connecting frame 5, thereby driving the drive wheel 51 to rotate along the guide rail 1. Since the drive wheel 51, the clamping wheel 53, the first driven wheel 521 and the second driven wheel 522 are all in contact with the guide rail 1, the control box 2 can move along the length of the guide rail 1 (affected by the rotation direction of the output shaft of the commutator 32).
[0036] Correspondingly, the controller 43 can be a microcontroller, which is an integrated circuit that integrates core components such as a central processing unit (CPU), memory (ROM, RAM), I / O interface, timer / counter, serial communication interface and interrupt system. The components work together to realize data operation, program and data storage, external device interaction, timing and counting, serial communication and real-time event response. It is an existing component, and its specific composition and working principle will not be described in detail here.
[0037] Furthermore, the detection component 4 also includes an alarm 44, which can be an audible and visual alarm 44. The alarm 44 is electrically connected to the controller 43. After the infrared temperature detection sensor 41 detects the temperature in the electrolytic cell, it sends the detection signal to the controller 43. The controller 43 processes the signal through its built-in program to determine whether the temperature in the electrolytic cell is in a normal state.
[0038] Specifically, the control box 2 is equipped with an insulating tube 8 (e.g., PVC material). The infrared temperature detection sensor 41 and the alarm 44 are located at the end of the insulating tube 8 away from the control box 2. The insulating tube 8 is hollow inside. The power lines of the infrared temperature detection sensor 41 and the alarm 44 are passed through the insulating tube 8 and electrically connected to the controller 43 inside the control box 2 to achieve electrical insulation.
[0039] If the temperature inside the current electrolytic cell is normal, the controller 43 will control the drive motor 31 to work, so that the connecting frame 5 carrying the control box 2 can continue to move to the next electrolytic cell.
[0040] If the temperature in the current electrolytic cell exceeds or falls below the set temperature, the infrared temperature sensor 41 will repeatedly measure the temperature of the current electrolytic cell (e.g., three or four times). If the temperature still deviates from the set value after the remeasurement, the controller 43 will control the alarm 44 to work to remind the staff to carry out maintenance.
[0041] Meanwhile, the control box 2 is also equipped with a network module 22, which is electrically connected to the controller 43 (e.g., WiFi module, mobile network module) to achieve the purpose of interacting with the mobile terminal. Therefore, the staff can receive the information processed by the controller 43 through the network module 22, so that the staff can view the temperature in the electrolytic cell, the movement direction of the control box 2 along the guide rail 1 on the connecting frame 5, and the cell number information of the electrolytic cell in real time.
[0042] Correspondingly, a display screen 9 is installed on the control box 2. The display screen 9 is electrically connected to the controller 43. The information processed by the controller 43 is directly displayed on the display screen 9, and the staff can quickly and directly observe the detection information through the display screen 9.
[0043] In addition, the control box 2 is equipped with a power supply module 7, which is electrically connected to the network module 22, the detection component 4 and the drive component 3 to provide power to them. The drive component 3 and the detection component 4 can be powered by the power supply module 7 without the need for an external power supply to the control box 2. When the power supply module 7 is low on power, it can be charged. This provides high flexibility and avoids the problem of wire tangling when the control box 2 moves back and forth along the guide rail 1.
[0044] It should be noted that the power supply module 7 mainly consists of a lithium battery pack, a battery protection circuit, a charging management circuit, and an output conditioning circuit. It is a conventional power supply component, and its specific composition and working principle will not be elaborated here.
[0045] It should also be noted that in this embodiment, both the guide rail 1 and the control box 2 are made of stainless steel, thereby giving them the ability to resist electromagnetic interference.
[0046] The implementation principle of an intelligent temperature measuring robot for electrolytic aluminum production according to an embodiment of this application is as follows: (Refer to...) Figure 4 The operator starts the controller 43, which supplies power to the detection component 4, drive component 3, and network module 22 via the power supply module 7. The controller 43 then executes the initialization program, and subsequently controls the drive motor 31 to start working. Through the cooperation of the first synchronous pulley 33, synchronous belt 34, and second synchronous pulley, the drive wheel 51 rotates along the guide rail 1, thereby causing the connecting frame 5, which carries the control box 2, to move along the guide rail 1. At this time, the position detector 421 detects the limit block 11 located on the guide rail 1. When the position detector 421 detects the position information of the limit block 11, the controller 43 controls the drive motor 31 to stop working, and simultaneously the slot number detection... The detector 422 detects the cell number of the current electrolytic cell to determine the cell number information. Subsequently, the temperature detection sensor detects the temperature of the current electrolytic cell, so that the temperature information of the current electrolytic cell corresponds to the cell number. The operator can directly observe the temperature information of the current electrolytic cell on a mobile terminal (such as a mobile phone or industrial control computer) or on the display screen 9 through the network module 22. When the temperature of the current electrolytic cell deviates from the set value, the controller 43 will control the alarm 44 to start working to remind the operator to inspect the current electrolytic cell. In the process of electrolytic aluminum production, this plays a positive guiding role in improving the convenience of temperature detection in the electrolytic cell.
[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
