[0001] The utility model relates to the field of aluminum electrolytic cell anode measuring tools, in particular to a clamping type aluminum electrolytic cell anode voltage drop measuring device. Background Art

[0002] The anode of an aluminum reduction cell is a key raw material in aluminum production. It acts as a conductor to conduct direct current into the electrolyte layer and, as a carbon material, participates in the anodic reaction of electrolysis. The anode portion of an aluminum reduction cell primarily consists of a carbonaceous electrode and a metallic anode conductor. During the aluminum production process, testing tools are required to measure and optimize the voltage drop within the anode to improve production efficiency and reduce energy consumption.

[0003] At present, a Chinese patent application with publication number CN219831234U and publication date October 13, 2023 proposes a portable aluminum electrolysis furnace bottom pressure drop measuring device, including a main drill rod, a protective sleeve and a fixed sleeve. The main drill rod is slidably provided with a protective sleeve, and the two ends of the main drill rod extend to the outside of the protective sleeve; the upper end of the protective sleeve is provided with a fixed sleeve, and the fixed sleeve is provided with a locking screw for locking the fixed sleeve on the protective sleeve; the upper end of the main drill rod is provided with a height adjustment mechanism, and the height adjustment mechanism is used to adjust the height position of the protective sleeve and the fixed sleeve on the fiber rod.

[0004] When in use, insert the measuring device (positive electrode) at a 45° angle into the aluminum water, about 5-8 cm away from the cathode surface. The upper end of the main drill rod of the voltage drop measuring device is connected to the multimeter through a wire. The other drill rod (negative electrode) contacts the cathode busbar of the electrolytic cell and is connected to the multimeter with a wire to form a measurement circuit. After the multimeter data stabilizes, record the reading.

[0005] With respect to the above-mentioned related technologies, each measurement requires two people to cooperate in placing the main drill rod and another drill bit against the measuring part for measurement. It is inconvenient for one person to simultaneously control the drill rod to abut against the measuring part and use a multimeter to read the reading. Utility Model Content

[0006] In order to improve the convenience of using an anode voltage drop detection device, the utility model provides a clamping type anode voltage drop measuring device for an aluminum electrolytic cell.

[0007] The utility model provides a clamping type anode voltage drop measuring device for aluminum electrolysis cell, which adopts the following technical solutions:

[0008] A clamping-type anode voltage drop measuring device for an aluminum electrolytic cell, characterized in that it comprises: a measuring meter, a first clamping member, a second clamping member, and a connecting rod provided on the first clamping member, wherein a first detection portion is provided at an end of the first clamping member, a second detection portion is provided at an end of the second clamping member, a connecting hole is provided at an end of the first clamping member away from the first detection portion, the connecting rod is fixedly provided at an end of the second clamping member away from the second detection portion, the connecting rod is passed through the connecting hole, and an elastic member is further provided between the first clamping member and the second clamping member, the elastic member having a tendency to bring the first clamping member and the second clamping member closer to each other;

[0009] The first clamping member is also provided with a first measuring point and a second measuring point. The first measuring point is connected to the first detection part through a conductor, the second measuring point is connected to the second detection part through a conductor, and the measurement meter is connected to the first measuring point and the second measuring point.

[0010] By adopting the above technical solution, when in use, the first clamping member is placed on the upper surface of the anode carbon block or other position of the anode part, and the first detection part is fitted and connected with the anode part, the second clamping member is extended into the aluminum electrolysis cell, and the second detection part is fitted and connected with the lower surface of the anode carbon block, and the connecting part provided on the second detection part is passed through the connecting hole on the first detection part. The first clamping member and the second clamping member will be clamped on the anode carbon block under the action of the elastic member. At the same time, since the anode carbon block will be continuously consumed, the first clamping member and the second clamping member will continue to approach and remain clamped on the anode carbon block under the action of the elastic member, so that the first detection part and the second detection part can maintain good contact with the measuring position. When measuring, the positive and negative poles of the measuring meter are connected to the first measuring point and the second measuring point respectively, and the voltage drop between the detection position of the first detection part and the detection position of the second detection part can be detected. In this way, when in use, the first clamping member and the second clamping member can be first fixedly clamped on the anode, and then the measuring meter can be used to detect at the first measuring point and the second measuring point. One person can complete the operation, which is convenient and fast. At the same time, since the first clamping member and the second clamping member are clamped and fixed by the elastic member, when replacing the anode carbon block, it is only necessary to loosen the elastic member to remove the first clamping member and the second clamping member from the anode. Disassembly and installation are convenient and fast, which can effectively save disassembly and assembly time.

[0011] Optionally, the elastic member is sleeved on the connecting rod, and a position control component is also provided on the connecting rod, the position control component includes a driving member and a sliding member, the driving member is provided at one end of the connecting rod away from the second clamping member, the sliding member is slidably provided on the connecting rod, the sliding member is provided between the driving member and the first clamping member, the sliding member and the driving member are transmission-connected, and the two ends of the elastic member are respectively connected to the sliding member and the first clamping member.

[0012] By adopting this technical solution, the position control assembly can control the sliding member to slide on the connecting rod through the driving member, and the elastic member is arranged between the sliding member and the first clamping member. When the sliding member slides on the connecting rod, the elastic force of the elastic member can be adjusted. When the driving member controls the sliding member to move in the direction close to the first clamping member, the elastic member is compressed to a larger deformation, and the first clamping member and the second clamping member are clamped more tightly under the action of the elastic member; when the driving member controls the sliding member to move in the direction away from the first clamping member, the elastic member is compressed to a smaller deformation, and the first clamping member and the second clamping member are clamped more loosely under the action of the elastic member, thereby facilitating the first clamping member and the second clamping member to be removed from the anode carbon block. In this way, through the setting of the position control assembly, the elastic force of the elastic member can be flexibly adjusted, and after a portion of the anode carbon block is consumed, the elastic force of the elastic member can be adjusted in time so that the first clamping member and the second clamping member can still be firmly clamped on the anode, thereby improving the conductivity between the first measuring part and the second measuring part and the anode carbon block.

[0013] Optionally, the position control component also includes a controller and a pressure sensing member, the pressure sensing member is fixedly mounted on the sliding member, the elastic member is connected to the pressure sensing member on the sliding member, the controller is fixedly mounted on the driving member, and the controller is electrically connected to the driving member and the pressure sensing member.

[0014] By adopting this technical solution, the pressure sensor can detect the pressure of the elastic member in real time. When a portion of the anode carbon block is consumed, the distance between the first clamping member and the second clamping member decreases, and the elastic force of the corresponding elastic member decreases accordingly. After the pressure sensor detects the decrease in the pressure exerted by the elastic member on the sliding member, it will feedback to the controller. The controller controls the operation of the driving member, which controls the sliding member to move toward the first clamping member, compressing the elastic member and increasing the elastic force, thereby providing greater clamping force for the first and second clamping members. In this way, through the configuration of the pressure sensor and the controller, the driving member can autonomously control the movement of the sliding member and automatically adjust the elastic force of the elastic member, improving the automation and intelligence of the device.

[0015] Optionally, a limiting block is provided on the connecting rod, a limiting groove is provided on the inner wall of the sliding member, and the limiting groove and the limiting block are arranged in coordination.

[0016] By adopting this technical solution, the cooperation between the limiting groove and the limiting block can reduce the rotation of the sliding part on the connecting rod and increase the stability of the sliding part when rotating on the connecting rod.

[0017] Optionally, the first detection portion is provided with a first abutting portion and a plurality of first elastic ejector pins, the first abutting portion and the first elastic ejector pins are both provided on an end surface of the first detection portion close to the second detection portion, and the plurality of first elastic ejector pins are all electrically connected to the first measuring point;

[0018] The second detection portion is provided with a second abutting portion and a plurality of second elastic ejector pins. The second abutting portion and the second elastic ejector pins are both provided on the end surface of the second detection portion close to the first detection portion. The plurality of second elastic ejector pins are all electrically connected to the second measuring point.

[0019] By adopting this technical solution, when the first clamping member and the second clamping member are clamped and fixed on the anode carbon block, the first abutting portion abuts against the upper surface of the anode carbon block, and the second abutting portion abuts against the lower surface of the anode carbon block. After the first abutting portion and the second abutting portion are clamped and fixed, the first elastic ejector pin and the second elastic ejector pin will respectively abut against the anode carbon block and the lower surface of the anode carbon block under the action of elastic force to measure the upper surface and lower surface of the anode carbon block. In this way, the use of the first abutting portion and the second abutting portion to abut and fix the upper surface and the lower surface of the anode carbon block can increase the stability of the first clamping member and the second clamping member on the anode carbon block. The use of the first elastic ejector pin and the second elastic ejector pin to measure the upper surface and the lower surface of the anode carbon block can cope with the uneven surface of the anode carbon block and increase the stability of the first detection portion and the second detection portion being electrically connected to the anode carbon block.

[0020] Optionally, a support tube is further provided on the first clamping member, the support tube is concentrically arranged with the connecting hole, the connecting rod is passed through the support tube, and the inner wall of the support tube is in contact with the outer wall of the connecting rod.

[0021] By adopting this technical solution, the connecting rod is passed through the support tube, and the interior of the support tube is in contact with the outer wall of the connecting rod. On the one hand, the support tube can limit the movement of the connecting rod, reduce the swing of the connecting rod when moving in the connecting hole, and increase the stability of the movement of the connecting rod; on the other hand, the support tube can support the connecting rod, reduce the deformation of the connecting rod when it is affected by the elastic part, and extend the service life of the connecting rod.

[0022] Optionally, the first clamping member is further provided with an extension rod and a clamping claw, one end of the extension rod is rotatably connected to one end of the first clamping member close to the first detection portion, and the clamping claw is fixedly provided at the other end of the extension rod.

[0023] By adopting this technical solution, the extension rod and the clamping claw can extend the extension rod when the first clamping member cannot be stably clamped on the anode carbon block, and the clamping claw at the end of the extension rod can be clamped on the anode guide rod or the anode steel claw, providing another optional fixing method for the first clamping member, reducing the probability that the first clamping member cannot be clamped and fixed on the surface of the anode carbon block when the top of the anode is uneven or tilted.

[0024] Optionally, the second clamping member and the connecting rod are made of ceramic material.

[0025] By adopting this technical solution, the second clamping member and the connecting rod need to be inserted into the electrolyte in the aluminum electrolysis cell for use. Since the temperature in the aluminum electrolysis cell is high and has certain corrosiveness, in order to reduce the impact of high temperature and corrosive environment on the second clamping member and the connecting rod, the use of high-temperature resistant and relatively stable ceramic materials can effectively extend the service life of the first clamping member and the connecting rod.

[0026] In summary, the present invention has at least one of the following beneficial technical effects:

[0027] The device is fixed on the anode by setting a clamping assembly, and the first detection part and the second detection part are set on the clamping assembly to measure the pressure drop of the anode carbon block. This eliminates the tedious operation of holding measuring tools and measuring meters for measurement every time, making it more convenient to use.

[0028] When the aluminum electrolytic cell is working, the anode carbon blocks will be continuously consumed. The elastic parts provide clamping force to the clamping assembly, which can still provide stable clamping force when the anode carbon blocks are consumed, reducing the probability of the clamping assembly falling off due to loose clamping. It is easy to disassemble and install, which is convenient for installing the device when replacing the anode carbon blocks.

[0029] By setting up a position control component and a pressure sensing component, on the one hand, the elastic component can be adjusted automatically according to the pressure of the elastic component, so that the elastic component can provide sufficient clamping force, further increasing the stability of the clamping component; on the other hand, the automation and intelligence level of the device is improved, human intervention is reduced, and it is more convenient to use.

In order to reduce the circumferential rotation of the sliding member 62 on the connecting rod 4, a protruding limit block 41 is further provided on the connecting rod 4. The limit block 41 extends along the axial direction of the connecting rod 4, and a limit groove 621 is provided on the inner wall of the sliding member 62 that cooperates with the limit block 41. The limiting groove 621 also extends along the axial direction of the connecting rod 4, and the sliding member 62 is also provided with a threaded hole in conjunction with the screw rod.

When in use, the voltage drop between the first measuring point 23 and the electrical measuring point measured by the measuring meter 1 is the voltage drop between the measurement positions of the first detection part 21 and the second detection part 31.

[0042] The specific implementation principle of the anode voltage drop measuring device of a clamping type aluminum electrolytic cell of the present utility model embodiment is as follows: during installation, the connecting rod 4 is passed through the connecting hole 22 from the direction of the supporting tube 25 of the first clamping member 2, and the elastic member 5 is sleeved on the connecting rod 4 after the connecting rod 4 passes through the connecting hole 22, and then the pressure sensing member 64 and the sliding member 62 are sleeved on the connecting rod 4 in sequence, and the driving member 61 and the sliding member 62 are installed in coordination, and the positions of the first clamping member 2 and the second clamping member 3 are adjusted, and the first clamping member 2 is placed on the upper surface of the anode carbon block, and the connecting rod 4 and the second clamping member 3 are inserted into the aluminum electrolytic cell to clamp the second clamping member 3 on the lower surface of the anode carbon block, and the positions of the first clamping member 2 and the second clamping member 3 are adjusted again so that they are firmly clamped on the anode carbon block. When the upper surface of the anode carbon block is inconvenient to clamp, the first clamping member 2 can be clamped on the anode guide rod or the anode steel claw by a claw hand. fixed in the row; during the consumption process of the anode carbon block in use, the second clamping member 3 will continuously move toward the first clamping member 2 under the action of the elastic member 5, and thus maintain clamping. When the anode carbon block is consumed too much and the elastic force provided by the elastic member 5 is small, when the pressure sensing member 64 senses that the pressure of the elastic member 5 is insufficient, the controller 63 controls the driving member 61 to work, and moves the sliding member 62 and the pressure sensing member 64 toward the direction close to the first clamping member 2, and squeezes the elastic member 5 so that it can provide sufficient elastic force to maintain the clamping force between the first clamping member 2 and the second clamping member 3. Since the first detection part 21 is connected to the first measuring point 23, and the second detection part 31 is connected to the second measuring point 24, the pressure drop between the detection positions of the first detection part 21 and the second detection part 31 can be measured by using the measuring table 1 to measure the first measuring point 23 and the second measuring point 24 set on the first clamping member 2.

[0043] In summary, the utility model uses a clamping component to be fixed on the anode, and a first detection part 21 and a second detection part 31 are set on the clamping component to measure the pressure drop of the anode carbon block, which eliminates the tedious operation of determining the measurement point and then using the measuring meter 1 to measure each time, and is more convenient to use; at the same time, the elastic part 5 provides a clamping force to the clamping component, so that the anode carbon block can still be clamped and fixed when it is consumed, reducing the probability of the clamping component falling off due to loose clamping, and is easy to disassemble and install, which is convenient for installing the device when replacing the anode carbon block; by setting the position control component 6 and the pressure sensing component 64, on the one hand, the elastic part 5 can be adjusted according to the pressure of the elastic part 5, so that the elastic part 5 can provide sufficient clamping force, further increasing the stability of the clamping component; on the other hand, the automation and intelligence of the device are improved, human intervention is reduced, and it is more convenient to use; the setting of the first measuring point 23 and the second measuring point 24 facilitates the use of the measuring meter 1 for connectivity detection, making the detection process more convenient.
