Description

Technical Field

[0001] This utility model relates to the technical field of cooling pools for graphite electrode production, and in particular to a cooling pool for graphite electrode production. Background Technology

[0002] In the production of graphite electrodes, the cooling process is the key to connecting high-temperature treatment with subsequent processing: after the electrodes are calcined and graphitized, the temperature reaches 800-1200℃, and they need to be cooled to below 50℃ before processing. If the cooling is not done properly, thermal stress can easily cause the electrodes to crack and deform, weakening their mechanical strength and conductivity.

[0003] Currently, most mainstream cylindrical graphite electrodes use spray cooling. However, due to shape limitations, the coolant can only cover the side of the electrode facing the spray head, and the side facing away from the spray head is difficult to contact with the coolant. If full circumferential cooling is required, the electrode must be flipped frequently by hand or with a robotic arm. Each cooling cycle requires multiple flips, which not only increases operating costs but also prolongs the cooling time of a single electrode due to the interruption of cooling during flipping, resulting in low cooling efficiency of the graphite electrode. To address this, we propose a cooling tank for graphite electrode production. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cooling pool for the production of graphite electrodes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cooling pool for graphite electrode production, comprising a cooling pool, a drive motor fixedly installed at the end of the cooling pool, a pull-out gear sleeved on the output shaft of the drive motor, two rolling plates rotatably installed on the inner walls of both sides of the cooling pool, a sliding plate slidably installed on the top of each of the two rolling plates, a linkage plate fixedly connected between the tops of the two sliding plates, a coolant tank fixedly installed on the top of the linkage plate, a pull-out rack slidably installed at the end of the cooling pool, and a lifting assembly provided inside the cooling pool.

[0006] Preferably, the top of the coolant tank is fixedly equipped with several sets of conveying pipes that are evenly spaced, and the ends of the several sets of conveying pipes extend to one side of the linkage plate and are fitted with coolant spray heads.

[0007] Preferably, the top of each of the two rolling plates is provided with a groove, and the two sliding plates are slidably connected in the two grooves respectively.

[0008] Preferably, a rotating shaft is fixedly connected to the outer side of each of the two rolling plates near one end, and the two rotating shafts are rotatably connected to the inner wall of the cooling pool. A lifting rod is fixedly connected between the two rolling plates near the other end.

[0009] Preferably, the lifting assembly includes an adjusting shaft, an adjusting wheel, and a rotating motor. The adjusting shaft is rotatably installed between the inner walls of the two sides of the cooling pool, corresponding to the area directly below the lifting rod. An elliptical adjusting wheel is fitted onto the outer wall of the adjusting shaft at the middle position. The adjusting wheel is in contact with the bottom of the lifting rod. A rotating motor is fixedly installed on the outer side of the cooling pool. The output shaft of the rotating motor extends rotatably into the cooling pool and is fixedly connected to one end of the adjusting shaft.

[0010] Preferably, the extraction rack extends slidably to the bottom of the linkage plate and is fitted with a stop bar, and the bottom of the extraction rack meshes with the extraction gear.

[0011] Preferably, a baffle is fixedly connected between the two sliding plates.

[0012] The beneficial effects of this utility model are:

[0013] In use, this invention features a tiltable rolling plate that allows the cylindrical graphite electrode to be cooled to roll along the plate under its own gravity. Combined with a coolant spray nozzle, the coolant fully covers the outer surface of the electrode during its rolling process. This eliminates the need for frequent manual or robotic flipping, achieving full circumferential cooling and effectively preventing problems such as electrode cracking and deformation caused by uneven cooling. This ensures the mechanical strength and conductivity of the electrode.

[0014] In use, this device utilizes a rotating motor to drive the adjusting shaft to rotate, causing the adjusting wheel to lift the lifting rod, which in turn tilts the rolling plate, providing a slope for the electrode to roll. Throughout the entire process, cooling continues during the electrode rolling without interruption due to flipping, greatly shortening the cooling time of a single electrode and significantly improving the cooling efficiency of the graphite electrode.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-4 As shown, a cooling pool for graphite electrode production is disclosed, comprising a cooling pool 1, a drive motor 2 fixedly mounted at the end of the cooling pool 1, a pull-out gear 3 sleeved on the output shaft of the drive motor 2, two rolling plates 4 rotatably mounted on the inner walls of both sides of the cooling pool 1, a sliding plate 6 slidably mounted on the top of each of the two rolling plates 4, a linkage plate 7 fixedly connected between the tops of the two sliding plates 6, a coolant tank 8 fixedly mounted on the top of the linkage plate 7, a pull-out rack 13 slidably mounted at the end of the cooling pool 1, and a lifting assembly provided inside the cooling pool 1. Compared with traditional spray cooling which requires frequent turning by manual labor or robotic arms, this device achieves automatic rolling and full-circumferential cooling of the electrodes through a mechanical structure, reducing manual operation and the use of robotic arms, and lowering operating costs.

[0024] Several sets of conveying pipes 9 are fixedly installed on the top of the coolant tank 8, and the ends of the several sets of conveying pipes 9 extend to one side of the linkage plate 7 and are fitted with coolant spray heads 10.

[0025] Both rolling plates 4 have grooves 11 on their tops, and two sliding plates 6 are slidably connected within the two grooves 11. By setting the tiltable rolling plates 4, a rolling slope is provided for the cylindrical graphite electrode, allowing the electrode to roll automatically under its own gravity. This ensures that the coolant sprayed from the coolant spray head 10 fully covers the outer surface of the electrode during its rolling process, eliminating the need for frequent manual or robotic flipping. This achieves full-circumferential cooling, effectively avoiding problems such as electrode cracking and deformation caused by uneven cooling, ensuring electrode quality, and significantly improving cooling efficiency. When the electrode rolls along the tilted rolling plates 4, it squeezes the sliding plates 6, causing the sliding plates 6 to slide in the grooves 11 on the top of the rolling plates 4 towards the rotation axis 5. The stable guidance effectively prevents the electrode from shifting during rolling, ensuring that the electrode always rolls along the predetermined path. This ensures that the coolant can be sprayed evenly on the electrode surface, improving the cooling effect and the reliability of the device.

[0026] Two rotating plates 4 are fixedly connected to a rotating shaft 5 near one end on their outer side. Both rotating shafts 5 are rotatably connected to the inner wall of the cooling pool 1. A lifting rod 17 is fixedly connected between the two rotating plates 4 near the other end.

[0027] The lifting assembly includes an adjusting shaft 15, an adjusting wheel 16, and a rotating motor 18. The adjusting shaft 15 is rotatably mounted between the inner walls of both sides of the cooling pool 1, directly below the lifting rod 17. An elliptical adjusting wheel 16 is fitted onto the outer wall of the adjusting shaft 15 at its center position. The adjusting wheel 16 is in contact with the bottom of the lifting rod 17. The rotating motor 18 is fixedly mounted on the outer side of the cooling pool 1. The output shaft of the rotating motor 18 extends rotatably into the cooling pool 1 and is fixedly connected to one end of the adjusting shaft 15. When the rotating motor 18 drives the adjusting shaft 15 to rotate, the elliptical adjusting wheel 16 rotates synchronously. Due to its special elliptical shape, it can gradually lift the lifting rod 17 during rotation, allowing the rolling plate 4 to smoothly tilt to a suitable angle, providing a stable and controllable slope for electrode rolling, ensuring the smoothness of the electrode rolling process and the stability of the cooling operation.

[0028] The extraction rack 13 slides to the bottom of the linkage plate 7 and is fitted with a stop bar 14. The bottom of the extraction rack 13 meshes with the extraction gear 3. When the side of the baffle 12 between the two sliding plates 6 contacts the stop bar 14, the drive motor 2 is started to drive the extraction gear 3 to rotate. The extraction gear 3 drives the extraction rack 13 to slide out of the cooling pool 1 through meshing with the extraction rack 13, which effectively controls the rolling process of the electrode. During the sliding process of the extraction rack 13, the electrode can continuously roll along the inclined rolling plate 4, realizing the automatic control of the cooling process and improving the ease of operation and cooling efficiency of the device.

[0029] A baffle 12 is fixedly connected between the two sliding plates 6.

[0030] Working Principle: In operation, the cylindrical graphite electrode to be cooled is first placed on top of the two rolling plates 4 and on one side of the two sliding plates 6. Simultaneously, the coolant tank 8 is activated, and the coolant tank 8 delivers coolant to the end coolant spray nozzles 10 via several sets of delivery pipes 9. The coolant spray nozzles 10 spray coolant onto the surface of the graphite electrode to initiate the initial cooling process. Next, the rotating motor 18 is activated. The output shaft of the rotating motor 18 drives the adjusting shaft 15 to rotate on both sides of the inner wall of the cooling pool 1. The elliptical adjusting wheel 16 on the outer wall of the adjusting shaft 15 rotates synchronously with it, gradually lifting the lifting rod 17 that is in contact with it. The lifting rod 17 rises, causing one end of the two rolling plates 4 to rise synchronously. The other end of the two rolling plates 4 rotates on the inner wall of the cooling pool 1 via the rotating shaft 5, ultimately causing the two rolling plates 4 to tilt, providing a rolling surface for the graphite electrode. Slope; After the rolling plate 4 is tilted, the graphite electrode rolls along the top of the rolling plate 4 towards the rotation axis 5 under its own gravity. During the rolling, it squeezes the two sliding plates 6, causing the sliding plates 6 to slide in the groove 11 at the top of the rolling plate 4 towards the rotation axis 5 to stabilize and guide the electrode and prevent it from shifting. When the side of the baffle 12 between the two sliding plates 6 contacts the baffle 14, the drive motor 2 is started. The drive motor 2 drives the extraction gear 3 to rotate. Through the meshing of the extraction gear 3 and the extraction rack 13, the extraction rack 13 is driven to slide out of the cooling pool 1. As the extraction rack 13 gradually slides outward, the graphite electrode can continue to roll along the tilted rolling plate 4 towards the rotation axis 5. During the rolling process, several sets of coolant spray heads 10 can fully cover the outer surface of the electrode, achieving full circumferential cooling without flipping, effectively avoiding cooling interruption and greatly improving cooling efficiency.
