Description

Technical Field

[0001] The present invention belongs to the technical field of submerged arc furnaces, and particularly relates to an intelligent electrode dropping measurement device and a method for using the same. Background Art

[0002] During the smelting process of an electric furnace, the working end of the electrode is continuously consumed. The function of the electrode dropping device is to periodically drop the electrode. Generally, small and medium-sized electric furnaces drop the electrode once per shift, and large electric furnaces drop the electrode twice per shift, so that the consumed part can be replenished to maintain a certain working length of the electrode. The amount of electrode dropping depends on the electrode consumption rate. Therefore, in production, it is necessary to timely grasp the real-time change of the electrode length. At present, the electrode length can usually only be obtained by manual measurement during furnace shutdown, and the length of the electrode cannot be measured in real time during furnace operation.

[0003] Existing submerged arc furnace electrode dropping measurement devices cannot completely solve the accurate and stable measurement of electrode dropping data. In practical applications, since the electrode barrel wall is a welded cylinder, there are weld beads or uneven pits on the electrode surface. During the measurement of electrode dropping, poor contact between the measuring wheel and the electrode barrel wall will occur, resulting in slipping or incomplete effective frictional resistance, causing the measuring wheel not to rotate and the stroke displacement not to be detected, resulting in no data being detected. When the submerged arc furnace is smelting, due to the action of electromagnetic field force, the electrode system generates high-frequency vibrations. In the past, the electrode measuring device was in hard contact with the electrode barrel wall, and the electrode vibration force would be directly transmitted to the electrode dropping amount measuring device, causing misreading of the measuring encoder pulse signal, inaccurate data, and easy damage to the rotating encoder electronic products, shortening the service life of the measuring device.

[0004] After retrieval, the patent with the publication number CN203432596U and the publication date of February 12, 2014 discloses an electrode dropping encoder with an insulating structure. The electrode dropping encoder is composed of an encoder body, a connecting shaft, and a measuring wheel. The encoder body is connected to the measuring wheel through the connecting shaft. Its characteristics are: an insulating layer is provided on the outer circumferential surface of the encoder body. The utility model can effectively prevent the electrode dropping encoder from being burned out due to the energization of the motor housing, extend the service life of the electrode dropping encoder, and reduce the replacement times of the electrode dropping encoder.

[0005] The following are the deficiencies of this patent:

[0006] 1. The distance between the encoder body of this measuring device and the electrode barrel is too close, and the high temperature and electromagnetic field force of the electrode barrel are likely to affect it, resulting in a low service life of the encoder;

[0007] 2. The measuring wheel of this device is in hard contact with the outer wall of the electrode barrel. The electrode vibration force will be directly transmitted to the electrode dropping amount measuring device, and when encountering weld beads or pits on the surface of the electrode barrel, the measuring wheel is likely to slip, resulting in the measuring wheel not rotating and affecting the measurement accuracy.

[0008] Therefore, the existing pressing and releasing measurement device cannot meet the requirements in actual use. So, there is an urgent need for improved technologies in the market to solve the above problems. Summary of the Invention

[0009] The object of the present invention is to provide an intelligent electrode pressing and releasing measurement device and its usage method. Through the action of a belt and a spring, the measuring wheel can always be pressed tightly against the outer wall of the electrode cylinder, solving the problems that there are welding beads or pits on the surface of the electrode cylinder, poor contact between the measuring wheel and the outer wall of the electrode cylinder, slipping or incomplete effective frictional resistance, resulting in the non-rotation of the measuring wheel, inability to detect the stroke displacement, and further inability to detect data.

[0010] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0011] The present invention is an intelligent electrode pressing and releasing measurement device, including a measuring mechanism and a buffer pressing mechanism. The measuring mechanism includes a measuring wheel, a first pulley, a belt, and a second pulley. The measuring wheel is fixedly sleeved on the middle part of a first rotating shaft. Both ends of the first rotating shaft are rotatably connected to their respective first bearing seats. A first pulley is also fixedly sleeved on the first rotating shaft. A belt is arranged between the first pulley and the second pulley;

[0012] The buffer pressing mechanism includes a fixing plate, a pressing rod, a fixed seat, and a spring. A chute is arranged on the inner side surface of the fixing plate. The first bearing seat is slidably matched with the chute. The pressing rod movably penetrates through the fixed seat. The fixed seat is fixed in the chute, and the end of the pressing rod is fixedly connected to the side surface of the first bearing seat. A spring is sleeved on the pressing rod.

[0013] Further, the measuring mechanism further includes a second rotating shaft, a second bearing seat, and an encoder. The second pulley is fixedly sleeved on the second rotating shaft. One end of the second rotating shaft is rotatably connected to the second bearing seat. The other end of the second rotating shaft is fixedly connected to the input end of the encoder.

[0014] Further, anti-slip teeth are arranged on the surface of the measuring wheel. The measuring wheel abuts against the outer wall of the electrode cylinder.

[0015] Further, one end of the spring is fixedly connected to the fixed seat, and the other end of the spring is fixedly connected to the first bearing seat. The initial state of the spring is a compressed state. Through the spring, it can always ensure that the measuring wheel is pressed tightly against the outer wall of the electrode cylinder.

[0016] Further, two buffer pressing mechanisms are provided. The two buffer pressing mechanisms are symmetrically arranged on both sides of the measuring wheel.

[0017] Further, it further includes a housing. The second bearing seat, the encoder, and the fixing plate are all fixed on the inner wall of the housing. A bottom mounting plate is fixed at the bottom of the housing, and the bottom mounting plate is provided as an insulating plate.

[0018] The present invention also provides a method for using the intelligent electrode pressure release measurement device, including the following steps:

[0019] S1: Fix the entire housing through the bottom mounting plate.

[0020] S2: When the electrode cylinder is lifted or lowered, it drives the measuring wheel to rotate. The measuring wheel drives the encoder to rotate through the transmission of the belt. Furthermore, the number of rotation circles of the measuring wheel can be detected by the encoder, and the data is fed back to the DCS, thereby realizing the measurement of the electrode pressure release depth.

[0021] S3: During the lifting and lowering process of the electrode cylinder, if the electrode cylinder vibrates, or the weld beads, pits, etc. on the surface affect the measuring mechanism, the measuring wheel is always pressed against the electrode cylinder through the buffer pressing mechanism, thereby eliminating the influence of the vibration of the electrode cylinder, the weld beads or pits on the surface on the measuring mechanism.

[0022] The present invention has the following beneficial effects:

[0023] 1. By setting the first pulley, the belt, and the second pulley in the present invention, the encoder is far away from the electrode cylinder, which can avoid the influence of the high temperature, electromagnetic field force, etc. of the electrode cylinder on it, and improve the service life of the encoder.

[0024] 2. By setting the sliding groove, the pressing rod, the fixing seat, and the spring in the present invention, the device has a pressing and buffering function. Through the action of the spring, the measuring wheel can always be pressed tightly against the outer wall of the electrode cylinder, solving the problems that there are weld beads or pits on the surface of the electrode cylinder, the contact between the measuring wheel and the outer wall of the electrode cylinder is poor, there is slipping or the frictional resistance is not completely effective, resulting in the non-rotation of the measuring wheel and the inability to detect the stroke displacement, and further resulting in the inability to detect data. By using the method of the present invention, the measurement of the electrode pressure release depth is effectively solved, external interference is prevented, and the measurement data is more accurate.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0034] Please refer to Figures 1-3 As shown, the present invention is an intelligent electrode pressure release measurement device, including a measurement mechanism 1 and a buffer and pressing mechanism 2. The measurement mechanism 1 includes a measurement wheel 11, a first belt pulley 15, a belt 16, a second belt pulley 17, and an encoder 110. Anti-slip teeth 12 are provided on the surface of the measurement wheel 11. The measurement wheel 11 abuts against the outer wall of the electrode cylinder 4. The measurement wheel 11 is fixedly sleeved in the middle of the first rotating shaft 13. Both ends of the first rotating shaft 13 are rotatably connected to their respective first bearing seats 14. A first belt pulley 15 is also fixedly sleeved on the first rotating shaft 13. A belt 16 is provided between the first belt pulley 15 and the second belt pulley 17. The second belt pulley 17 is fixedly sleeved on the second rotating shaft 18. One end of the second rotating shaft 18 is rotatably connected to the second bearing seat 19. The other end of the second rotating shaft 18 is fixedly connected to the input end of the encoder 110.

[0035] When the measurement mechanism 1 is specifically used, when the electrode cylinder 4 moves up and down, it drives the measurement wheel 11 to rotate. The measurement wheel 11 drives the first rotating shaft 13 and the first belt pulley 15 to rotate. The first belt pulley 15 drives the second belt pulley 17 to rotate through the belt 16. The second belt pulley 17 drives the second rotating shaft 18 to rotate. The second rotating shaft 18 drives the encoder 110 to rotate. Thus, the number of rotation turns of the measurement wheel 11 can be detected by the encoder 110, and the data is fed back to the DCS, and the measurement of the electrode pressure release depth can be realized.

[0036] Among them, as shown in Figures 1-2 Figures 3 and 4, the buffer tightening mechanism 2 includes a fixing plate 21, a tightening rod 23, a fixed seat 24 and a spring 25. A sliding groove 22 is provided on the inner side surface of the fixing plate 21. The first bearing seat 14 is slidably matched with the sliding groove 22. The tightening rod 23 movably penetrates through the fixed seat 24. The fixed seat 24 is fixed in the sliding groove 22, and the end of the tightening rod 23 is fixedly connected to the side surface of the first bearing seat 14. A spring 25 is sleeved on the tightening rod 23. One end of the spring 25 is fixedly connected to the fixed seat 24, and the other end of the spring 25 is fixedly connected to the first bearing seat 14.

[0037] There are two buffer tightening mechanisms 2, and the two buffer tightening mechanisms 2 are symmetrically arranged on both sides of the measuring wheel 11.

[0038] When the buffer tightening mechanism 2 is specifically used, when the electrode cylinder 4 moves up and down, it drives the measuring wheel 11 to rotate. When the electrode cylinder 4 vibrates, or there are welding beads or pits on its surface, the measuring wheel 11 will be squeezed or separated from the electrode cylinder 4. At this time, the measuring wheel 11 drives the first bearing seat 14 to move along the sliding groove 22, the tightening rod 23 moves along the through hole of the fixed seat 24, and the spring 25 is compressed. Under the reset acting force of the spring 25, the measuring wheel 11 can always be tightly pressed against the outer wall of the electrode cylinder 4, so as to eliminate the influence of the vibration of the electrode cylinder 4 and the welding beads or pits on the surface on the measuring mechanism 1.

[0039] Among them, as shown in Figures 1-2 Figure 5, it further includes a housing 3. The second bearing seat 19, the encoder 110 and the fixing plate 21 are all fixed on the inner wall of the housing 3. The bottom of the housing 3 is fixed with a bottom mounting plate 31. The bottom mounting plate 31 is set as an insulating plate, and the overall insulation can be realized through the insulating plate, which is safer and more reliable.

[0040] The present invention also provides a use method of the intelligent electrode pressing and releasing measuring device, including the following steps:

[0041] S1: Fix the entire housing 3 through the bottom mounting plate 31;

[0042] S2: When the electrode cylinder 4 moves up and down, it drives the measuring wheel 11 to rotate. The measuring wheel 11 drives the encoder 110 to rotate through the transmission of the belt 16. Furthermore, the rotation number of the measuring wheel 11 can be detected through the encoder 110, and the data is fed back to the DCS, so as to realize the measurement of the electrode pressing and releasing depth;

[0043] S3: During the up and down movement of the electrode cylinder 4, if the electrode cylinder 4 vibrates, or the welding beads or pits on the surface affect the measuring mechanism 1, the measuring wheel 11 is always pressed against the electrode cylinder 4 through the buffer tightening mechanism 2, so as to eliminate the influence of the vibration of the electrode cylinder 4 and the welding beads or pits on the surface on the measuring mechanism 1.

[0044] The above are only the preferred embodiments of the present invention and do not limit the present invention. Any modification of the technical solutions recorded in the foregoing embodiments, any equivalent replacement of some technical features, and any modification, equivalent replacement, or improvement made thereto all fall within the protection scope of the present invention.
