Description

Technical Field

[0001] This utility model relates to the technical field of aluminum electrolysis production equipment, specifically to a measuring device for anode carbon blocks. Background Technology

[0002] The anode carbon block in electrolytic aluminum is the positive electrode in the electrolytic cell. It is made of petroleum coke, asphalt, etc., and is mostly rectangular block structure. During the electrolysis process, the anode carbon block is the core component of the electrolytic cell. It usually needs to maintain a relatively consistent height at both ends. Its top is connected to the anode guide rod (or steel claw), and its bottom is in direct contact with the electrolytic melt to participate in the electrochemical reaction. If the height difference between the two ends is too large, the contact area and distance between the two ends of the carbon block and the electrolyte will be inconsistent, resulting in excessively high local current density, accelerating the local consumption of the carbon block (forming "eccentric corrosion"), and shortening its service life. Moreover, a large height difference will make the current concentration area prone to local high temperature, causing problems such as electrolyte overheating and excessive carbon slag, affecting the stability of the electrolytic cell.

[0003] Currently, anode carbon block production workshops typically use a height measuring device on the forming machine to measure the height of the anode carbon blocks. However, this device can only measure the height of one end of the raw anode carbon block, and the height of the other end cannot be measured in real time. This easily results in carbon blocks with heights at both ends exceeding the allowable error range, leading to a large number of waste blocks and seriously affecting the product qualification rate. Therefore, it is necessary to design a device with measurement capabilities at both ends to solve the above-mentioned problems.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the background technology of this disclosure and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] In view of at least one of the above technical problems, this disclosure provides a measuring device for an anode carbon block, which aims to solve the problem that the measuring devices in the prior art cannot simultaneously measure the height of both ends of the anode carbon block.

[0006] According to one aspect of this disclosure, a measuring device for an anode carbon block is provided, comprising: a base, a support frame fixed on the base, positioning screws symmetrically and rotatably mounted in the support frame, positioning support plates mounted on the support frame, measuring mechanisms symmetrically and movably disposed on the positioning support plates, and a driving mechanism mounted in the base, wherein the two ends of the positioning support plates are movably sleeved on the support frame and threadedly sleeved on the positioning screws; the bottom surface of the positioning support plates is further provided with symmetrical pressure sensors, and the measuring mechanism is connected to the pressure sensors.

[0007] Furthermore, the measuring mechanism includes movable columns symmetrically and movably mounted on the positioning support plate and a connecting base plate connected between the lower ends of the movable columns. The pressure sensor is located between the movable columns, and a measuring spring is also connected between the pressure sensor and the connecting base plate.

[0008] Furthermore, a horizontal connecting rod is provided below the connecting base plate, and a movable sleeve block is movably sleeved on the connecting rod, with a contact block connected to the lower end of the movable sleeve block.

[0009] Furthermore, the drive mechanism includes a drive rod rotatably passing through the base, a plurality of lower bevel gears fixedly mounted on the drive rod, and a drive motor mounted on the outside of the base, wherein the drive motor is connected to the drive rod.

[0010] Furthermore, the lower end of the positioning screw extends into the base, and an upper bevel gear is provided on the lower end of the positioning screw, which meshes with the lower bevel gear.

[0011] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0012] 1. The device of this application has the function of measuring both ends of the anode carbon block. When the device is running, the measuring mechanism, in conjunction with the pressure sensor and connected to a computer remotely, can measure whether the heights of the two ends of the anode carbon block are consistent. If the data displayed by the computer are consistent, the heights of the two ends of the anode carbon block are consistent; if the data displayed by the computer are inconsistent, the heights of the two ends of the anode carbon block are inconsistent. At the same time, the difference in the displayed values ​​can also be used to indirectly determine the height difference between the two ends of the anode carbon block, so that the molding workers can make timely adjustments and improve the production qualification rate.

[0018] This application provides a measuring device for anode carbon blocks, which solves the problem that existing measuring devices cannot simultaneously measure the height of both ends of the anode carbon block. To better understand the technical solution of this application, the above technical solution will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] This example discloses a measuring device for anode carbon blocks, see [link to relevant documentation]. Figures 1-3 The device includes a base 1, a support frame 2 fixed on the base 1, positioning screws 3 symmetrically and rotatably installed in the support frame 2, positioning support plates 4 installed on the support frame 2, measuring mechanisms 5 symmetrically and movably installed on the positioning support plates 4, and a driving mechanism 6 installed in the base 1. The two ends of the positioning support plates 4 are movably sleeved on the support frame 2 and threadedly sleeved on the positioning screws 3. The bottom surface of the positioning support plates 4 is also provided with symmetrical pressure sensors 7, and the measuring mechanism 5 is connected to the pressure sensors 7.

[0020] The measuring mechanism 5 includes movable columns 51 symmetrically and movably mounted on the positioning support plate 4 and a connecting base plate 52 connected between the lower ends of the movable columns 51. A pressure sensor 7 is located between the movable columns 51, and a measuring spring 55 is connected between the pressure sensor 7 and the connecting base plate 52. A horizontal connecting rod 53 is also provided below the connecting base plate 52, and a movable sleeve block 54 is movably mounted on the connecting rod 53. A contact block 56 is connected to the lower end of the movable sleeve block 54.

[0021] The drive mechanism 6 includes a drive rod 61 rotatably inserted into the base 1, a plurality of lower bevel gears 63 fixedly mounted on the drive rod 61, and a drive motor 62 mounted on the outside of the base 1. The drive motor 62 is connected to the drive rod 61. The lower end of the positioning screw 3 extends into the base 1, and an upper bevel gear 31 is also provided on the lower end of the positioning screw 3. The upper bevel gear 31 meshes with the lower bevel gears 63.

[0022] Working principle: When implementing the device of this application, the pressure sensor 7 can be electrically connected to the computer, and the computer can monitor the pressure value generated by the pressure sensor 7 in real time. Then, the anode carbon block to be measured is placed at the center of the base 1. Next, the drive motor 62 is started to drive the device to operate. The drive motor 62 drives the drive rod 61 to rotate. The lower bevel gear 63 rotates synchronously with the drive rod 61 and drives the upper bevel gear 31 meshing with it to rotate synchronously. The upper bevel gear 31 drives the positioning screw 3 to rotate. The synchronously rotating positioning screw 3 drives the positioning support plate 4 to move downward, and the measuring mechanism 5 moves downward synchronously. When the contact block 56 abuts against the surface of the anode carbon block and the measuring spring 55 is in a compressed state, the drive motor 62 is turned off to stop the device from moving. At this time, the readings of the two pressure sensors 7 can be read by the computer. The pressure value is used to determine whether the heights of the two ends of the anode carbon block are consistent. When the heights of the two ends of the anode carbon block are equal, the two symmetrical contact blocks 56 and the connecting base plate 52 are on the same horizontal plane, the compression degree of the measuring spring 55 is the same, and the spring force received by the pressure sensor 7 is also the same. When the heights of the two ends of the anode carbon block are not equal, the contact blocks 56 are staggered and abut against the two ends of the carbon block. At this time, the compression degree of the measuring spring 55 is also different, and the spring force received by the pressure sensor 7 is also different. The staff can judge whether the carbon block meets the standard by the data transmitted to the computer. If the two values ​​are similar, the height difference is small; if the two values ​​are large, the height difference is large. When the heights of the two ends are found to be inconsistent, the molding worker can make timely adjustments to level the material to make the heights of the two ends of the carbon block equal, thereby improving the appearance qualification rate of the raw block. In addition, when measuring the height, the movable sleeve 54 is movable, which can measure whether the corresponding positions at the two ends of the anode carbon block are level.

[0023] In addition, the drive motor 62 and pressure sensor 7 used in the device of this application are existing technologies, and the way the pressure sensor 7 is connected to the computer to transmit data is also existing technology. The specific working principle will not be described in detail in this technical solution.
