Abstract
Description
Technical Field
[0001] This utility model belongs to the field of metallurgical measurement technology, specifically relating to a calcium carbide furnace electrode measuring device. Background Technology
[0002] In the calcium carbide production process, monitoring the condition of the furnace electrodes is crucial. The calcium carbide furnace transmits a powerful current through the electrodes, generating high temperatures to induce a chemical reaction that produces calcium carbide. The electrodes are continuously consumed during use, and changes in their weight directly reflect their wear and tear. Accurate measurement of electrode weight plays a key role in controlling the calcium carbide furnace's production process, ensuring production efficiency, and maintaining product quality.
[0003] However, existing electrode measurement technologies for calcium carbide furnaces have many problems. For example, traditional measurement methods often rely on manual periodic measurements, which are not only inefficient but also difficult to monitor in real time, especially in the high-temperature, high-dust, and high-electromagnetic-interference environments of calcium carbide furnace production.
[0004] Furthermore, some existing measuring devices typically use the method of placing the electrodes directly above the gravity sensor for measurement, which lacks the ability to fix the electrodes. When the calcium carbide furnace is running, the electrodes will be affected by vibration, thermal expansion and contraction, etc. If they are not fixed firmly, the electrodes are very easy to shift or loosen, resulting in poor accuracy of the measurement data.

Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention.

[0027] Example
[0028] Reference Figures 1-4 This is an embodiment of the present invention, which provides a calcium carbide furnace electrode measuring device, comprising:
[0029] The gravity sensor body 100 is a prior art device used to detect the weight of electrodes. It includes a base 110, an elastic member 120 fixedly mounted on the outer surface of the base 110, a mounting plate 130 fixedly connected to the top of the elastic member 120, and a strain gauge 140 disposed inside the elastic member 120.
[0030] It should be noted that the base 110 is the basic support structure for the gravity sensor body 100, used to firmly fix it at the relevant position of the calcium carbide furnace, providing a stable mounting platform for other components. When the electrode is placed on the mounting plate 130, its weight will cause the elastic component 120 to undergo elastic deformation. Based on the elastic properties of the material, this deformation is proportional to the electrode weight, providing a physical basis for subsequent electrical signal conversion. The mounting plate 130 is used to support the electrode to be measured. It not only provides a placement plane for the electrode but also transfers the weight of the electrode to the elastic component 120. When the elastic component 120 deforms due to the electrode weight, the resistance value of the strain gauge 140 will change accordingly. According to the resistance strain effect, when the electrode is placed on the mounting plate 130, its weight causes the elastic component 120 to undergo elastic deformation, and the electrode weight... The larger the weight, the greater the deformation of the elastic component 120. The strain gauge 140 will be stretched or compressed as the elastic component 120 deforms, and its resistance value will change accordingly. Within the elastic range, when the strain gauge 140 is stretched, its resistance value increases; when it is compressed, its resistance value decreases. An increase in electrode weight will cause the elastic component 120 to stretch and deform more, thus causing the strain gauge 140 to be stretched and its resistance value to increase. Conversely, when the electrode weight decreases, the deformation of the elastic component 120 decreases, the stretching of the strain gauge 140 weakens, and its resistance value decreases. By measuring the change in the resistance value of the strain gauge 140, it can be converted into an electrical signal to realize the measurement of the electrode weight. The gravity sensor body 100 is in the prior art, and this solution will not describe it in detail. Moreover, those skilled in the art can clearly understand its working principle.
[0031] The positioning mechanism 200 includes a clamping assembly 210 for fixing the electrode to be measured to the surface of the mounting plate 130, which is located on the outside of the mounting plate 130.
[0032] The clamping assembly 210 includes a fixing block 211 fixedly connected to both sides of the mounting plate 130, a rotating rod 212 fixedly mounted on the top of the fixing block 211 by a bearing, a cam 213 fixedly sleeved on the outer surface of the rotating rod 212, and a first slider 214 and a force plate 215 respectively provided on both sides of the cam 213.
[0033] It should be noted that the fixing block 211 provides a mounting base for components such as the rotating rod 212 and the guide block 218, ensuring the structural stability of the entire clamping assembly 210. The rotating rod 212 can rotate flexibly, driving the cam 213 to rotate. The cam 213 then drives the first slider 214 and the force plate 215 to move towards each other. The first slider 214 applies pressure to the electrode, clamping it. At the same time, the force plate 215 drives the transmission rod 216 and the second slider 217 to move synchronously, causing the second slider 217 to move closer to the first slider 214, clamping the electrode from both sides. The guide block 218 provides guidance for the movement of the first slider 214 and the second slider 217, ensuring they maintain linear motion during movement. The first spring 219 drives the first slider 214 and the second slider 217 when the external force of the cam 213 is removed, facilitating the next operation.
[0034] Specifically, the clamping assembly 210 also includes a transmission rod 216 fixedly connected to the inner surface of the first slider 214, and a second slider 217 fixedly connected to the other end of the transmission rod 216 and used in conjunction with the force plate 215.
[0035] Furthermore, the clamping assembly 210 also includes a guide block 218 fixedly connected to the top of the fixing block 211 and used in conjunction with the first slider 214 and the second slider 217, and a first spring 219 sleeved on the outside of the transmission rod 216.
[0036] The two ends of the first spring 219 abut against the first slider 214 and the second slider 217 respectively, and the outer surfaces of the first slider 214 and the second slider 217 slide in contact with the inner walls of the guide blocks 218 on both sides respectively.
[0037] Preferably, the positioning mechanism 200 also includes a locking assembly 220 located below the cam 213 for locking the rotating rod 212 and preventing the force plate 215 and the second slider 217 from shifting positions.
[0038] It should be noted that the locking assembly 220 includes a rotating post 221 fixedly connected to the top of the fixing block 211, and a pawl 222 rotatably sleeved on the outside of the rotating post 221.
[0039] Furthermore, the locking assembly 220 also includes a ratchet 223 that engages with the outer surface of the pawl 222 and is used in conjunction with the rotating rod 212, and a second spring 224 that is fixedly connected to the top of the fixing block 211 and is used in conjunction with the ratchet 223.
[0040] It should be explained that the rotating column 221 is used to provide a mounting shaft for the pawl 222, allowing the pawl 222 to rotate around it. When the rotating rod 212 rotates and drives the cam 213 to rotate to clamp the electrode, the ratchet 223 rotates synchronously. At this time, the pawl 222 remains engaged with the ratchet 223 under the reaction action of the second spring 224, preventing the rotating rod 212 from rotating in the opposite direction due to external force, ensuring the stability of the first slider 214 and the second slider 217, and avoiding displacement or loosening of the electrode during the measurement process, which would affect the measurement accuracy.
[0041] Specifically, the ratchet 223 is fixedly sleeved on the outer surface of the rotating rod 212, and the second spring 224 and the pawl 222 abut against each other.
[0042] When in use, the base 110 of the device is securely installed at the relevant position of the calcium carbide furnace to provide stable support for the entire measuring device;
[0043] Next, place the electrode to be measured on the mounting plate 130, and then rotate the rotating rod 212 to drive the cam 213 to rotate. The cam pushes the first slider 214 and the force plate 215 on both sides to move towards each other, so that the first slider 214 applies pressure to the electrode. At the same time, the force plate drives the transmission rod 216 and the second slider 217 to move synchronously, clamping the electrode from both sides. During this process, the guide block 218 ensures that the first slider 214 and the second slider 217 can only move in a straight line.
[0044] During electrode clamping, the rotating rod 212 drives the ratchet 223 to rotate synchronously. The pawl 222 is engaged with the ratchet 223 under the action of the second spring 224, preventing the rotating rod 212 from rotating in the opposite direction due to external force, ensuring the stability of the electrode fixed position, and avoiding electrode displacement or loosening during measurement, which would affect the measurement accuracy.
[0045] During the test: The weight of the electrode causes the elastic component 120 to undergo elastic deformation, which in turn causes the resistance value of the strain gauge 140 to change with the degree of deformation of the elastic component. When the strain gauge 140 is stretched, the resistance value increases; when it is compressed, the resistance value decreases. The increase in electrode weight causes the elastic component 120 to undergo more stretching deformation, which in turn causes the strain gauge 140 to be stretched and the resistance value to increase. Conversely, when the electrode weight decreases, the degree of deformation of the elastic component 120 decreases, the degree of stretching of the strain gauge 140 weakens, and the resistance value decreases. By measuring the change in the resistance value of the strain gauge 140, it can be converted into an electrical signal to measure the weight of the electrode.
[0046] In summary, through the cooperation of the gravity sensor body 100 and the clamping mechanism 200, not only can the deformation of the elastic component 120 caused by the weight of the electrode be accurately converted into an electrical signal by the strain gauge 140, and the weight of the electrode be accurately measured, but also displacement or loosening of the electrode can be prevented during the weight measurement process, ensuring the stability of the measurement data, so as to meet the production requirements for accurate measurement of electrode weight.
