Description

Technical Field

[0001] The utility model relates to the field of Acheson graphitization furnace power transmission device, in particular to an Acheson furnace power transmission vehicle with rapid heat dissipation. Background Art

[0002] Acheson graphitization furnace is a resistance furnace that uses carbon roasted products and resistor materials as the furnace core, passes AC power, and produces artificial graphite products. When the current passes through the resistance of the furnace core, the electrical energy is converted into heat energy, heating the carbon roasted products to a high temperature of 2300-3000℃, completing the graphitization process and forming artificial graphite products. The Chinese name is AC graphitization furnace, and it is also customarily called Acheson furnace.

[0003] Acheson furnaces are intermittently operated. In one production cycle, they have to go through processes such as furnace loading, power supply, cooling, furnace unloading, and maintenance, which takes a total of 12 to 15 days, and power supply only takes 3 to 5 days. Generally, one transformer can be equipped with 5 to 7 furnaces of the same specifications to form a furnace group, and a furnace group is a production unit. During production, the transformer runs continuously and the furnaces work in turn; usually one furnace in a furnace group is in the power-on state, and the other furnaces are in the states of furnace loading, cooling, loading and unloading or maintenance; after one furnace is finished working, power is supplied to the next furnace.

[0004] Each furnace has multiple rows and columns of rectangular graphite electrodes (such as Fig.16 As shown), the electrodes are used for wiring; a set of rectangular cross-section busbars (aluminum bars) are suspended at both ends of the furnace group, and the transformer supplies power to the furnace group through the busbars. Each furnace group is usually equipped with two Acheson furnace power transmission vehicles, which can run along the steel rails on the ground at both ends of the furnace group and can stop at the end of any furnace in the furnace group; the power transmission vehicle is equivalent to a large mobile combination switch, connecting the transformer power transmission busbar (the busbar is divided into upper and lower types) and the furnace's graphite electrode to energize the furnace. The basic structural principle can be found in the Chinese patent publication number CN115200364A.

[0005] The busbar clamping mechanism and electrode clamping mechanism are installed on the power transmission car, which can clamp the power transmission busbar and the graphite electrode of the furnace respectively; the busbar clamping mechanism and the electrode clamping mechanism are connected by a conductive copper plate or cable. Due to the masonry error of the Acheson furnace and long-term use, the graphite electrode may change position or deflect; similarly, the installation error of the busbar relative to the furnace and long-term use will also cause the busbar to change position and deflect. Fig.16 As shown, Fig.16 The graphite electrodes 9 at the upper left corner and the upper right corner have changed their positions, and the graphite electrodes 9 at the lower left corner and the lower right corner have deviated.

[0006] If the contact surface between the electrode clamping mechanism and the electrode does not match, the graphite electrode will be easily broken due to the unbalanced load, shortening its service life; and additional loss of electric energy will be caused due to poor contact. If the busbar clamping mechanism does not have good contact with the clamping surface of the busbar, it will cause excessive oxidation of the busbar and additional loss of electric energy. Therefore, the clamping mechanism of the busbar and the electrode is required to have a follow-up function that can deflect with the deflection of the busbar or the graphite electrode, so that the clamping mechanism is always in close contact with the busbar and the electrode, and clamps stably and reliably.

[0007] The Chinese patent with publication number CN202310255343.1 provides a clamping mechanism, which has the following problems.

[0008] 1. The clamping plate 311 can only rotate on a single axis relative to the clamping arm 313. Due to the processing and manufacturing errors, installation errors, and deviations caused by long-term use of the electrode, the electrode position changes and the rectangular cross-section of the electrode is skewed. When the electrode clamping mechanism clamps the electrode, the clamping plate opening is not aligned with the electrode, and the contact surface between the clamping plate and the electrode is not parallel or coincident, and cannot fit tightly. When the clamping plate is in poor contact with the furnace end graphite electrode, the oil cylinder driving force is very large, and the lever force of the clamping plate to clamp the graphite electrode is very large; once the graphite electrode and the clamping plate are out of contact, the graphite electrode not only bears the clamping force of the clamping plate, but also bears the bending moment or torque caused by the mismatch between the contact surface between the clamping plate and the electrode, which can easily cause the graphite electrode to break and shorten the service life of the electrode; at the same time, due to poor contact, it also causes additional loss of electric energy. Similarly, poor contact between the clamping surface of the clamping plate and the busbar will cause excessive oxidation of the busbar, increasing additional loss of electric energy.

[0009] 2. The structure of the clamping mechanism is relatively complex and is a multi-link mechanism. There are two articulated shafts 3135 and two transmission rods 315 and 316 between the clamping arm and the transmission rod; the two transmission rods are subjected to great force and are easily deformed, which affects the dimensional accuracy of the clamp and further affects the alignment and fit between the clamp and the electrode; the multi-link structure of two transmission shafts and two transmission rods has strict requirements on processing accuracy and high processing costs.

[0065] Optionally, the connecting member is a universal joint, and the two ends of the universal joint are respectively fixedly connected or rotationally connected to the clamping part 3 and the fixing seat 2. When the two ends of the universal joint are fixedly connected to the clamping part 3 and the fixing seat 2, the clamping part 3 has two rotational degrees of freedom; when one end of the universal joint is rotationally connected to the clamping part 3 or the fixing seat 2, the clamping part 3 has three rotational degrees of freedom.

[0066] Optionally, the connecting member includes a first spherical member 22 and a second spherical member 33, the first spherical member 22 is fixed relative to the fixed seat 2, the first spherical member 22 forms a first spherical surface 221, the second spherical member 33 is fixed relative to the clamping portion 3, the second spherical member 33 forms a second spherical surface 331, and the first spherical surface 221 and the second spherical surface 331 are in contact with each other.

[0067] When the electrode is clamped, the first spherical surface 221 and the second spherical surface 331 are always tightly fitted, and the spherical casting 33 can make the clamping part 3 have a tilt range, which can be used to clamp the graphite electrode 9 with an uneven surface or a certain tilt angle, and the second spherical part 33 can be adaptively rotated and adjusted according to the shape of the graphite electrode 9 to ensure the stability of the clamping.

[0068] Alternatively, if Figures 4 to 8 As shown, the first spherical surface 221 of the first spherical member 22 is a spherical concave surface, and the second spherical surface 331 of the second spherical member 33 is a spherical convex surface.

[0069] Alternatively, if Figure 12 to Figure 14 As shown, the first spherical surface 221 of the first spherical member 22 is a spherical convex surface, and the second spherical surface 331 of the second spherical member 33 is a spherical concave surface.

[0070] The radii of the spherical convex surface and the spherical concave surface are the same.

[0071] Furthermore, the clamping device further includes a limiting member 23 , which is used to limit the second spherical member 33 from being out of contact with the first spherical member 22 .

[0072] Furthermore, the limiting member 23 includes a nut 231, a gasket 232, an elastic element 233 and a threaded member 234. The threaded member 234 passes through the fixing seat 2 and is threadedly connected to the second spherical member 33.

The nut 231 is threadedly connected to the threaded member 234 and contacts one end of the gasket 232 away from the elastic element 233.

[0073] Alternatively, if Figure 7 and Figure 8 As shown, the first spherical member 22 and the fixing seat 2 are respectively provided with through holes, and the threaded member 234 passes through the through holes of the first spherical member 22 and the fixing seat 2, and the diameter is smaller than the inner diameters of the two through holes, so that the threaded member 234 can have a certain inclination angle in the through hole. Among them, the inner diameter of the through hole of the first spherical member 22 is smaller than the inner diameter of the through hole of the fixing seat 2, one end of the elastic element 233 contacts the first spherical member 22 and is smaller than the inner diameter of the through hole, and the other end of the elastic element 233 contacts the gasket 232. The diameters of the gasket 232 and the nut 231 are smaller than the inner diameter of the through hole of the fixing seat 2.

[0074] Alternatively, if Fig.12 and Fig.14 As shown, the fixing seat 2 is formed with a stepped hole, one end of the elastic element 233 is located in the stepped hole and contacts the step surface, and the other end of the elastic element 233 contacts the gasket 232. The screw member 234 is smaller than the minimum inner diameter, and the screw member 234 can swing a certain angle in the stepped hole.

[0075] Preferably, the elastic element 233 is a disc spring. The disc spring has the advantages of small axial size and large elastic element force; one of the two nuts 231 closer to the disc spring can adjust the size of the disc spring force to ensure that the spherical pair is in reliable contact (tightening) and can rotate flexibly; when adjusted to a suitable state, tighten the second nut 231 to prevent loosening.

[0076] Furthermore, it also includes a lubricating oil cup 24, the fixing seat 2 is formed with a first through hole 21, the first spherical part 22 is formed with a second through hole 222, the first through hole 21 and the second through hole 222 are connected, and the lubricating oil cup 24 is inserted into the first through hole 21 and fixedly connected to the fixing seat 2. The ball head parts are made of high-quality medium carbon steel, and the hardness and wear resistance are improved after heat treatment. After heat treatment, the contact surfaces of the concave and convex spheres are repeatedly ground to achieve a very high roughness. At the same time, high-temperature resistant lubricating grease is regularly added to the contact surface of the spherical pair through the lubricating oil cup 24. These measures greatly reduce the friction between the spherical pairs, so that the rotation resistance of the electrode plate 31 with the graphite electrode 9 is greatly reduced.

[0077] When working, Fig.19 As shown, the wheels of the moving device 71 are above the track 83 and adapted to the track 83 , the busbar 81 is located between the track 83 on both sides (lower type) or above the track groove 82 (upper type), and the busbar 81 and the track 83 are both located in the track groove 82 .

[0078] When the power transmission vehicle moves along the track 83 to the end of a furnace 91 of the Acheson furnace group, it hits the limit switch and stops moving. The opening of the clamping device is aligned with the graphite electrode 9 connected to the furnace end, but the clamping part 3 is at a safe distance from the end of the graphite electrode 9. When power is required, the first drive device 74 (a hydraulic cylinder can be used) pushes the mounting plate 73 to move linearly toward the graphite electrode 9 until the graphite electrode 9 is located between the two electrode plates 31 of the clamping device, and then the mounting plate 73 stops moving. The drive device 5 drives the clamping part 3 to move toward each other to clamp the graphite electrode 9. During the clamping process, if the position and size of the graphite electrode 9 (or busbar) deviates or the electrode is skewed due to the masonry error of the furnace 91 or the installation error of the busbar, the clamping part 3 rotates around the fixed seat 2 and automatically aligns and fits with the graphite electrode 9.

[0079] The graphite electrodes 9 are usually arranged in multiple rows and columns, so the number and arrangement size of the clamping devices are consistent with the graphite electrodes 9 .

[0080] Afterwards, the driving device 89 drives the sliding frame 85 to move towards the bus bar 81 until the bus bar 81 is located between the two bus bar electrode plates 87. Then, the first driving device 88 drives the two rotating frames 86 to rotate towards each other, and the bus bar electrode plates 87 clamp the bus bar 81, thereby transmitting electricity to the graphite electrode 9.

[0081] The present invention is described above by way of examples, but the present invention is not limited to the above specific embodiments, and any changes or modifications based on the present invention belong to the scope of protection required by the present invention.
