Description

[0001] The utility model belongs to the technical field of graphite electrodes, and in particular relates to a graphite electrode position correction device. Background Art

[0002] At present, graphite electrodes are made of raw materials such as coke and asphalt through batching, preheating, kneading, extrusion and other processes to form green billets, and then the green billets are sent to a cooling water pool for cooling. The existing conventional cooling water pool is usually equipped with an inclined plane. When the green billets enter the water, they are often placed on the top of the inclined plane, and the height difference of the inclined plane is used to directly roll the green billets into the cooling water pool. However, in actual operation, since the placement of the green billets on the top of the inclined plane is often done manually, the rising and falling positions of the green billets cannot be accurately centered, and the green billets are prone to tilt during subsequent rolling, resulting in more serious bumps on the green billets and their final position in the cooling water pool is biased, making it difficult to maintain the middle position, which is not conducive to salvage after cooling, and needs to be improved.

The piston rod of the single-rod hydraulic cylinder faces downward and is fixedly connected to the top end of the baffle. The single-rod hydraulic cylinder is electrically connected to the controller.

[0006] Preferably, rotating shafts are fixedly connected to both the front and rear ends of the upper part of the baffle. The two rotating shafts are rotatably connected to the front and rear side walls of the cooling water pool, and one of the rotating shafts extends out of the cooling water pool and is drivingly connected to a second motor.

In this way, the effective centering correction of the position of the green body of the graphite electrode on the inclined plane can be realized, which can better make the final position of the green body in the cooling water tank be in the middle position, effectively reduce the collision of the green body, and is more conducive to salvage after cooling, which is more practical. In addition, through the detachable connection between the correction plate and the corresponding support rod, the convenient disassembly and assembly of the correction plate can be realized. When the correction plate is damaged due to external erosion or collision, it can be flexibly replaced to ensure the smooth progress of the correction operation, making the overall use of the device more flexible and convenient.

Specific embodiments

[0025] The present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0026] Embodiment 1: As Figures 1 to 10As shown in the figure, a graphite electrode position correction device includes a cooling water pool 1 and an inclined plane 2 provided on one side of the cooling water pool 1. Inside the cooling water pool 1 above the lower end of the inclined plane 2, a baffle 3 is vertically provided. The baffle 3 can move above the cooling water pool 1, and a pressure sensor 4 is embedded on the side of the baffle 3 close to the higher end of the inclined plane 2. Along the front-rear direction, an inverted U-shaped support plate 5 is fixedly provided on the top of the cooling water pool 1 on the side of the baffle 3 close to the higher end of the inclined plane 2. A first motor 6 is fixedly mounted on the horizontal part of the support plate 5. The output shaft of the first motor 6 penetrates downward through the horizontal part of the support plate 5 and is fixedly sleeved with a gear 7. Both the left and right sides of the gear 7 are meshed and connected with racks 8. The tops of the two racks 8 are both slidably connected to the bottom of the horizontal part of the support plate 5. One end of each of the two racks 8 away from the gear 7 is fixedly connected with an inverted L-shaped support rod 9. Inside the upper part of the vertical part of one support rod 9, a distance sensor 10 is fixedly provided, and inside the upper part of the vertical part of the other support rod 9, a measuring block 11 is fixedly provided. The distance sensor 10 corresponds to the measuring block 11. The lower parts of the inner sides of the vertical parts of the two support rods 9 are both detachably connected with correction plates 12. The distance between the two correction plates 12 is the same as the distance between the distance sensor 10 and the measuring block 11. A controller 13 is fixedly provided on the outside of the cooling water pool 1. The pressure sensor 4, the first motor 6, and the distance sensor 10 are all electrically connected to the controller 13;

[0027] When cooling the green body of the graphite electrode, the green body can be first placed at the highest end of the inclined plane 2, and the green body rolls down along the inclined plane 2. When it reaches the baffle 3, it can be blocked and intercepted by the baffle 3. At the same time, since the green body gives pressure to the baffle 3, it can be detected by the pressure sensor 4 and fed back to the controller 13. The controller 13 can automatically control the first motor 6 to rotate forward. Through the transmission of the gear 7 and the racks 8, the two correction plates 12 can be driven to move synchronously relative to each other, so as to be able to push the green body to the middle position. During the process, the distance sensor 10 can detect the distance between it and the measuring block 11 in real time and feed it back to the controller 13. This distance is the distance between the two correction plates 12. When this distance reaches the set length of the green body, it means that the two correction plates 12 just touch both ends of the green body and at this time the green body has been corrected to the middle position. The controller 13 can automatically control the first motor 6 to reverse, so that the two correction plates 12 move away from each other synchronously and reset, and control the baffle 3 to move above the cooling water pool 1 to release the block on the green body, so that the green body can continue to roll down to the cooling water pool 1 along the middle position. In this way, the effective centering correction of the position of the graphite electrode green body on the inclined plane 2 can be realized, which can better make the final position of the green body in the cooling water pool 1 be in the middle position, can effectively reduce the bumps suffered by the green body, and is more conducive to salvage after cooling, and is more practical. In addition, through the detachable connection between the correction plate 12 and the corresponding support rod 9, the convenient disassembly and assembly of the correction plate 12 can be realized. When the correction plate 12 is damaged due to external erosion or collision, it can be flexibly replaced to ensure the smooth progress of the correction operation, making the overall use of the device more flexible and convenient.

[0028] In this embodiment, an inverted U-shaped bracket 14 is fixedly arranged along the front-back direction on the upper edge of the top of the cooling water tank 1 corresponding to the baffle 3. A single-rod hydraulic cylinder 15 is vertically fixedly arranged on the horizontal part of the bracket 14. The piston rod of the single-rod hydraulic cylinder 15 faces downward and is fixedly connected to the top end of the baffle 3. The single-rod hydraulic cylinder 15 is electrically connected to the controller 13. After the position of the green body is corrected, the single-rod hydraulic cylinder 15 can be operated to contract its piston rod, so as to drive the baffle 3 to rise above the cooling water tank 1, thereby removing the blockage of the green body and enabling the green body to continue to roll down smoothly.

[0029] In this embodiment, a slider 16 is fixedly arranged on the top of the rack 8. A chute 17 is formed along the front-back direction on the bottom of the horizontal part of the corresponding support plate 5 where the slider 16 is located. The slider 16 is slidably arranged on the corresponding chute 17 to effectively guide and limit the movement of the rack 8, so as to ensure the smooth synchronous relative or opposite movement between the two correction plates 12.

[0030] In this embodiment, a square positioning seat 18 is fixedly arranged on the lower part of the inner side of the vertical part of the support rod 9. A double-rod hydraulic cylinder 19 is arranged inside the positioning seat 18. The double-rod hydraulic cylinder 19 is electrically connected to the controller 13, and the two piston rods of the double-rod hydraulic cylinder 19 can extend out of the positioning seat 18. A positioning groove 20 adapted to the positioning seat 18 is formed on the upper part of one side of the correction plate 12 close to the corresponding support rod 9. The correction plate 12 is sleeved outside the corresponding positioning seat 18 through the positioning groove 20. Limit blind holes 21 adapted to the piston rods of the double-rod hydraulic cylinder 19 are formed on the two groove walls of the positioning groove 20 corresponding to the two piston rods of the double-rod hydraulic cylinder 19. The piston rods of the double-rod hydraulic cylinder 19 are inserted into the corresponding limit blind holes 21. When it is necessary to replace the correction plate 12, only in the shutdown state, first operate the double-rod hydraulic cylinder 19 to contract its two piston rods to reset, so as to release the plug-in limit of the correction plate 12, and then pull out the correction plate 12 from the positioning seat 18, and the original correction plate 12 can be disassembled. Then, after taking a new correction plate 12, first align the positioning groove 20 thereon with the positioning seat 18 and sleeved in place, and then operate the double-rod hydraulic cylinder 19 to extend its two piston rods until they are inserted in place in the corresponding limit blind holes 21 to plug and fix the correction plate 12, and the installation and fixation of the new correction plate 12 can be completed, and the fixation is firm without affecting subsequent use. In this way, the convenient disassembly and assembly of the correction plate 12 can be realized, and the correction plate 12 can be flexibly replaced when it is damaged due to external erosion or collision, ensuring the smooth progress of the correction operation and making the overall use of the device more flexible and convenient.

[0031] In this embodiment, a plurality of through holes 22 are formed on both the baffle 3 and the correction plate 12, which is convenient for water flow to pass through and reduces the water resistance when the corresponding plate moves. The hole shape of the through hole 22 is not limited to the circular hole shown in the figure, and can also be a square or other shaped holes, which can be specifically selected according to actual needs.

[0032] In this embodiment, the calibration plate 12 is an aluminum foam plate. Aluminum foam is an existing material, which has characteristics such as high damping shock absorption and energy absorption, anti-corrosion and corrosion resistance, etc. It can better ensure the service life of the calibration plate 12, and reduce the damage to the green body when calibrating the position of the green body, making it more practical.

[0033] Embodiment 2: The parts that are the same as those in Embodiment 1 will not be described in detail. The differences are as follows: As Figure 11 and Figure 12 shown, both the front and rear ends of the upper part of the baffle 3 are fixedly connected with rotating shafts 23. The two rotating shafts 23 are rotatably connected to the front and rear side walls of the cooling water tank 1, and one of the rotating shafts 23 extends out of the cooling water tank and is drivingly connected with a second motor 24. The second motor 24 is electrically connected to the controller 13. After the position of the green body is calibrated, the second motor 24 can be operated. With the cooperation of the rotating shaft 23, the entire baffle 3 can be driven to flip more than 90 degrees in the direction of the lower end of the inclined surface 2, so as to drive the baffle 3 to rise above the cooling water tank 1, thereby removing the blockage of the green body and enabling the green body to continue to roll down smoothly. The second motor 24 can adopt an existing conventional stepping motor with a brake function to cooperate to realize the rotation of a corresponding angle and the position locking after the rotation in place.

[0034] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
