The intelligent smelting system of the ore-fired furnace is equipped with an electrode, wherein one end of the electrode is buried in the material. When the electrode is energized, the electrode transmits the current into the material layer, and the material is energized and generates heat due to its own resistance, thereby realizing the heating of the material by the electrode. However, in the actual production process, the electrode will be continuously consumed, so new electrodes need to be continuously pressed and released for replenishment. This requires accurate measurement of the electrode pressing and releasing amount to achieve accurate statistics of the actual electrode consumption.

[0003] In the related art, manual measurement or measurement through a pull-rope sensor is usually used. However, the above methods require human intervention during use. For example, when manual measurement is used, a ruler needs to be used to measure each time the electrode is consumed for a certain distance. When a pull-rope sensor is used for measurement, after the pull rope moves a certain distance, the measuring point needs to be moved manually, resulting in low measurement efficiency and inaccurate measurement.

[0033] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0034] The electrode pressure release measuring device 100 and the intelligent smelting system 200 of an arc furnace according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0035] like Figure 1-Figure 2 As shown, the electrode pressure release measuring device 100 according to the embodiment of the first aspect of the utility model includes: a mounting frame 1, a displacement sensor 2, a clamping device 3 and a driving device 4, the clamping device 3 is used to clamp the outer side of the electrode cylinder 202, and can follow the electrode cylinder 202 to move from the first position to the second position, when the clamping device 3 is located at the second position B, the clamping device 3 releases the electrode cylinder 202; wherein, the first position A is located on the side of the second position B away from the material 203, the displacement sensor 2 is fixed to the mounting frame 1, the displacement sensor 2 is used to measure the displacement of the clamping device 3, so as to measure the displacement of the electrode 201 along the pressure release direction X, the driving device 4 is fixed to the mounting frame 1, the driving device 4 is used to drive the clamping device 3 to move from the second position B to the first position A when the clamping device 3 releases the electrode cylinder 202, and when the clamping device 3 moves to the first position A, the clamping device 3 clamps the electrode cylinder 202.

[0036] Specifically, Figure 1 As shown, the intelligent smelting system 200 of the submerged arc furnace includes an electrode 201 and an electrode cylinder 202. The electrode 201 and the electrode cylinder 202 are both made of conductive materials. For example, the electrode 201 and the electrode cylinder 202 can be made of metals such as copper and aluminum. The electrode cylinder 202 can be constructed as a cylindrical hollow structure. The electrode 201 is fixedly installed in the electrode cylinder 202. When the intelligent smelting system 200 of the submerged arc furnace is running, the electrode cylinder 202 drives the electrode 201 to be pressed toward the material 203. That is to say, Figure 1 As shown, the electrode cylinder 202 and the electrode 201 move downward together so that one end of the electrode 201 is inserted into the material 203. When the electrode 201 is energized, the current in the electrode 201 is passed into the material 203, and the material 203 is heated and melted under the action of its own resistance. At the same time, the electrode 201 and the electrode cylinder 202 are also continuously consumed during the power-on process. Therefore, in the production process of the intelligent smelting system 200 of the electric arc furnace, it is necessary to continuously press and release to replenish the electrode 201 and the electrode cylinder 202.

[0037] Further, continue to refer to Figure 1As shown, the intelligent smelting system 200 of the electric arc furnace is used to measure the displacement of the electrode 201. The electrode pressure release measuring device 100 includes a clamping device 3 and a displacement sensor 2, wherein the displacement sensor 2 is fixedly mounted on the mounting frame 1, and the clamping device 3 is assembled with the outer wall of the electrode tube 202. Specifically, the outer wall of the electrode tube 202 has a rib plate 2021, and the clamping device 3 can selectively clamp or release the rib plate 2021.

[0038] When the clamping device 3 clamps the rib plate 2021, the clamping device 3 can move downward along the pressure-release direction X along with the electrode tube 202 and the electrode 201, and the displacement sensor 2 is used to detect the movement of the clamping device 3. For example, the displacement sensor 2 can be an infrared sensor, a camera sensor, or a photoelectric sensor. It is selected according to actual needs. No specific restrictions are made here. It is sufficient to be able to obtain the displacement of the clamping device 3 in real time. It can be understood that the displacement of the clamping device 3 is the pressure-release amount of the electrode 201 moving downward, that is, the pressure-release amount of the electrode 201 is determined by measuring the displacement of the clamping device 3 fixed on the electrode tube 202, thereby accurately obtaining the consumption of the electrode 201.

[0039] It should be noted that during the downward pressing of the electrode 201 and the electrode tube 202, the clamping device 3 gradually moves toward the material 203. In order to avoid contact between the clamping device 3 and the material 203, the position of the clamping device 3 needs to be readjusted. In the past, manual measurement and adjustment were required. On the one hand, manual adjustment is inefficient. On the other hand, manual measurement and adjustment may lead to large errors, thereby affecting the accuracy of the subsequent measurement of the electrode 201 pressing amount.

[0040] Based on this, the clamping device 3 in the present application is provided with a first position A and a second position B, wherein the second position B is closer to the material 203 than the first position A. Specifically, the second position B is the lowest position that the clamping device 3 can reach when following the electrode cylinder 202 to move downward, and the first position A is the highest position that the clamping device 3 can reach when adjusting upward. For example, Figure 1 As shown, the second position B is the position when the clamping device 3 and the displacement sensor 2 are at a distance of L0, and the first position A is the position when the clamping device 3 and the displacement sensor 2 are at a distance of Lm. It should be noted that when the clamping device 3 and the displacement sensor 2 are at a distance of L, the real-time displacement of the clamping device 3 measured by the displacement sensor 2 is Lx, wherein Lx=L-L0.

[0041] Furthermore, in order to solve the disadvantages in the manual adjustment process, the electrode pressure release measuring device 100 is also provided with a driving device 4. Specifically, the driving device 4 can be used to drive the clamping device 3 to move when the clamping device 3 releases the rib plate 2021 to realize automatic adjustment of the position of the clamping device 3.

[0042] As a specific example, it is assumed that the clamping device 3 clamps the rib 2021 in the initial stage, and the clamping device 3 is fixedly connected to the electrode cylinder 202. When the electrode 201 and the electrode cylinder 202 move downward along the pressing direction X, the clamping device 3 moves downward with the electrode 201 and the electrode cylinder 202, that is, it moves from the first position A to the second position B. When the displacement sensor 2 detects that the clamping device 3 moves to the second position B, that is, when the clamping device 3 moves to a distance L0 from the displacement sensor 2, the clamping device 3 releases the rib 2021 of the electrode cylinder 202. At this time, the clamping device 3 can move relative to the electrode cylinder 202. It should be noted that, if Figure 2 As shown, during the movement of the clamping device 3, the rib plate 2021 is always in contact with the clamping device 3. With this arrangement, the rib plate 2021 can play a certain guiding role, thereby preventing the clamping device 3 from separating from the electrode cylinder 202 and ensuring the accuracy of position adjustment.

[0043] Furthermore, after the clamping device 3 releases the rib 2021 of the electrode tube 202, the clamping device 3 is driven to move upward by the driving device 4. Optionally, the driving device 4 can be directly driven or indirectly driven, and no specific restrictions are made here. The clamping device 3 is driven to move to the first position A by the driving device 4. When the displacement sensor 2 detects that the clamping device 3 moves to the first position A, the clamping device 3 re-clamps the rib 2021, so that the clamping device 3 can move downward together along the pressing direction X during the pressing and releasing process of the electrode tube 202 and the electrode 201. The displacement sensor 2 is used to detect the displacement of the clamping device 3. In this way, the position point of the clamping device 3 is adjusted upward by the driving device 4, which can not only prevent the clamping device 3 from continuing to move downward and contacting the material 203, but also realize the reset measurement of the displacement of the clamping device 3 in the next stage, that is, the cyclic reset of the measuring point and the automatic measurement of the pressing and releasing amount of the electrode 201 are realized. The whole process does not require manual intervention, and the automation level is high. At the same time, manual adjustment errors are avoided, which is conducive to improving the accuracy of measurement.

[0044] According to the electrode pressure release measuring device 100 of the embodiment of the utility model, the measuring device utilizes the displacement sensor 2 to realize the measurement of the pressure release amount of the electrode 201. At the same time, the measurement point can be reset by driving the movement of the clamping device 3 through the driving device 4, thereby realizing the continuous automatic measurement of the pressure release amount of the electrode 201. The whole process does not require human intervention, and the automation level is high. At the same time, manual adjustment errors are avoided, which is conducive to improving the accuracy of the measurement.

[0045] In some embodiments of the present invention, Figure 1 As shown, along the pressing direction X, the clamping device 3 is located on the side of the driving device 4 away from the mounting frame 1.

[0046] Specifically, Figure 1 As shown, along the pressing direction X of the electrode 201, the mounting frame 1, the driving device 4 and the clamping device 3 are arranged in sequence, that is, the driving device 4 is arranged above the clamping device 3. It can be understood that the first position A to which the clamping device 3 can be moved is located below the driving device 4. With this arrangement, the driving device 4 can directly pull up the clamping device 3, and the transmission distance is shorter, which is conducive to improving the transmission efficiency.

[0047] In some embodiments of the present invention, Figure 1 As shown, it also includes: a first connecting member 5, a driving device 4 is connected to the clamping device 3 through the first connecting member 5, and the driving device 4 is used to drive the clamping device 3 to move through the first connecting member 5 when the clamping device 3 releases the electrode cylinder 202.

[0048] Specifically, Figure 1 As shown, the first connecting member 5 is connected between the driving device 4 and the clamping device 3. When the displacement sensor 2 detects that the clamping device 3 follows the electrode 201 and the electrode cylinder 202 to move to the second position B, the clamping device 3 releases the electrode cylinder 202, that is, releases the rib 2021 of the electrode cylinder 202. The driving device 4 drives the clamping device 3 to move upward through the first connecting member 5 to move the clamping device 3 to the first position A. For example, the driving device 4 is arranged above the clamping device 3. The driving device 4 can be set as a driving cylinder, and the first connecting member 5 can be set as a telescopic rod, which is connected between the driving cylinder and the clamping device 3. When the clamping device 3 releases the rib 2021, the telescopic rod is retracted by the driving cylinder to drive the clamping device to move upward. Further, the driving device 4 can be set as a driving motor, and the first connecting member 5 can be set as a screw rod, which is connected between the driving motor and the clamping device 3. The tightening device can also be moved upward by driving the screw rod driven by the driving motor. With such arrangement, the transmission is performed through the first connecting member 5, which can realize the flexible arrangement of the relative positions of the clamping device 3 and the driving device 4 while satisfying the driving requirements of the clamping device 3, and is conducive to the rational use of the installation space.

[0049] In some embodiments of the present invention, Figure 1 As shown, the driving device 4 is a hoisting device, the first connecting member 5 is a hoisting rope, and the hoisting device is connected to the clamping device 3 through the hoisting rope.

[0050] Specifically, Figure 1As shown, the driving device 4 can be constructed as a winch lifting device, which includes a driving motor and a winch shaft. The driving motor drives the winch shaft to rotate, and the winch shaft is connected to the clamping device 3 through a winch rope. When the clamping device 3 moves to the second position B and releases the rib plate 2021, the driving motor drives the winch shaft to rotate, and the winch shaft winds the winch rope to move upward, thereby driving the clamping device 3 to move to the first position A through the winch rope. When the clamping device 3 moves to the first position A, the driving motor stops working, and the winch shaft no longer pulls the winch rope upward. At this time, the clamping device 3 clamps the rib plate 2021 of the electrode cylinder 202 to prepare for the next measurement cycle. With this arrangement, the overall structure of the winch lifting device and the winch rope is relatively simple. Through the coordinated use of the winch lifting device and the winch rope, the automatic adjustment of the measuring position of the clamping device 3 is met, and it is beneficial to save the modification cost.

[0051] In some embodiments of the present invention, Figure 1 As shown, along the pressing direction X, the displacement sensor 2 is located on the side of the clamping device 3 away from the driving device 4.

[0052] Specifically, Figure 1 As shown, along the pressing and releasing direction X of the electrode 201, the driving device 4, the clamping device 3 and the displacement sensor 2 are arranged in sequence, that is, the displacement sensor 2 is arranged below the clamping device 3. It can be understood that the second position B to which the clamping device 3 can be moved is located above the displacement sensor 2, that is, the distance between the clamping device 3 and the displacement sensor 2 in the up and down directions is detected by the displacement sensor 2. For example, a laser sensor can be used to irradiate a laser upward onto the clamping device 3 to determine the spacing between the two, or a camera sensor can be used to directly obtain the spacing between the two. No specific restrictions are made here. Such an arrangement can ensure the detection accuracy of the position of the clamping device 3, which is beneficial to improving the measurement accuracy of the pressing and releasing amount of the electrode 201.

[0053] In some embodiments of the present invention, Figure 1 As shown, it also includes: a second connecting member 6 , the displacement sensor 2 is connected to the clamping device 3 through the second connecting member 6 , and the displacement sensor 2 measures the displacement of the clamping device 3 through the second connecting member 6 .

[0054] Specifically, Figure 1As shown, the second connecting member 6 is connected between the displacement sensor 2 and the clamping device 3. The displacement sensor 2 determines the displacement of the clamping device 3 by measuring the moving distance of the second connecting member 6. For example, the second connecting member 6 is fixedly connected to the clamping device 3. When the clamping device 3 moves downward following the electrode 201 and the electrode cylinder 202, the second connecting member 6 moves downward. The displacement sensor 2 can obtain the compression and release amount of the electrode 201 by measuring the distance the second connecting member 6 moves downward. When the displacement sensor 2 detects that the clamping device 3 moves to the second position B, the clamping device 3 releases the rib plate 2021, and the driving device 4 drives the clamping device 3 to move upward. The displacement sensor 2 can obtain the upward movement amount of the clamping position by measuring the distance the second connecting member 6 moves upward, so as to determine whether the clamping device 3 reaches the first position A. In this way, the compression and release amount of the electrode 201 is obtained by measuring the actual moving distance of the second connecting member 6 by the displacement sensor 2, which is conducive to improving the detection accuracy of the compression and release amount.

[0055] In some embodiments of the present invention, Figure 1 As shown, the displacement sensor 2 is a pull-wire type sensor, the second connecting member 6 is a pull wire, and the pull-wire type sensor is connected to the clamping device 3 via the pull wire.

[0056] Specifically, Figure 1 As shown, the displacement sensor 2 can be constructed as a wire-drawing sensor, which is connected to the clamping device 3 through a wire, wherein one end of the wire is fixedly connected to the clamping device 3, and when the clamping device 3 moves downward following the electrode 201 and the electrode cylinder 202, the wire connected to the wire-drawing sensor will retract into the wire-drawing sensor, so that the downward movement of the clamping device 3 can be determined by measuring the retraction amount of the wire, and then the compression and release amount of the electrode 201 can be determined. Further, when the driving device 4 drives the clamping device 3 to move upward, the wire connected to the wire-drawing sensor extends out of the wire-drawing sensor under the drive of the clamping device 3, so that the upward movement of the clamping device 3 can be determined by measuring the extension amount of the wire, and then it can be determined whether the clamping device 3 reaches the first position A. In this way, the compression and release amount of the electrode 201 can be accurately measured by the coordinated use of the wire-drawing sensor and the wire, and the structure is simple and reliable, and the cost is low.

[0057] In some embodiments of the present invention, Figure 1 As shown, it also includes: a controller 7, which is used to control the clamping device 3 to loosen the electrode tube 202 when the clamping device 3 is located at the second position B, and control the driving device 4 to drive the clamping device 3 to move toward the first position A, and when the clamping device 3 moves to the first position A, control the clamping device 3 to clamp the electrode tube 202.

[0058] Specifically, the controller 7 is respectively connected to the clamping device 3, the driving device 4 and the displacement sensor 2 in communication, and the communication connection mode includes but is not limited to wired communication, Bluetooth communication, etc. The controller 7 obtains the data of the displacement sensor 2 and the working status of the clamping device 3 in real time. Further, as a specific example, it is assumed that the controller 7 controls the clamping device 3 to clamp the rib 2021 of the electrode cylinder 202 in the initial stage. When the electrode 201 and the electrode cylinder 202 move downward along the pressing direction X, the clamping device 3 moves downward with the electrode 201 and the electrode cylinder 202. When the displacement sensor 2 detects that the clamping device 3 moves When it moves to the second position B, the controller 7 controls the clamping device 3 to loosen the rib 2021 of the electrode tube 202, and then controls the driving device 4 to drive the clamping device 3 to move toward the first position A. When the displacement sensor 2 detects that the clamping device 3 moves to the first position A, the controller 7 controls the clamping device 3 to re-clamp the rib 2021, thereby preparing for the next stage of measurement of the displacement of the clamping device 3, that is, the cyclic resetting of the measuring point and the automatic measurement of the compression and release amount of the electrode 201 are realized. The whole process does not require manual intervention, and the level of automation is high. At the same time, manual adjustment errors are avoided, which is conducive to improving the accuracy of the measurement.

[0059] like Figure 1 As shown, according to the second aspect of the embodiment of the utility model, the intelligent smelting system 200 of the electric arc furnace includes: an electrode pressure-release measuring device 100, an electrode 201 and an electrode tube 202. The electrode pressure-release measuring device 100 is the electrode pressure-release measuring device 100 in the first aspect of the embodiment. The electrode 201 is arranged in the electrode tube 202. The electrode tube 202 can drive the electrode 201 to move toward the material 203 along the pressure-release direction X of the electrode 201.

[0060] According to the intelligent smelting system 200 of the electric arc furnace of the embodiment of the utility model, by setting the above-mentioned electrode pressure release measuring device 100, the measuring device uses the displacement sensor 2 to realize the measurement of the pressure release amount of the electrode 201. At the same time, the measurement point can be reset by driving the movement of the clamping device 3 by the driving device 4, thereby realizing the continuous automatic measurement of the pressure release amount of the electrode 201. The whole process does not require human intervention, and the automation level is relatively high. At the same time, it avoids manual adjustment errors, which is conducive to improving the accuracy of the measurement.

[0061] In some examples of the present invention, Figure 1 and Figure 2As shown, the electrode barrel 202 has a rib plate 2021, and the rib plate 2021 extends along the pressing and releasing direction X, and the clamping device 3 can selectively clamp or release the rib plate 2021. In other words, by arranging the rib plate 2021 on the electrode barrel 202, it is convenient to clamp or release the assembly between the clamping device 3 and the electrode barrel 202, which is conducive to improving the assembly efficiency, and then improving the automation efficiency. At the same time, the rib plate 2021 extends along the pressing and releasing direction X. During the movement of the clamping device 3, the rib plate 2021 is always in contact with the clamping device 3. The rib plate 2021 can play a certain guiding role in the pressing and releasing direction X, which is conducive to ensuring the accuracy of the position adjustment of the clamping device 3.
