Description

Technical Field

[0001] This utility model relates to the field of electrode lifting technology for four-electrode submerged arc furnaces, specifically to an automatic lifting and adjusting mechanism for the electrodes of a four-electrode submerged arc furnace. Background Technology

[0002] A four-electrode submerged arc furnace is a piece of equipment used in the metallurgical industry for reducing and smelting raw materials such as ores. It has four electrodes arranged in a rectangular shape, and the electrodes are generally made of graphite or self-baking electrodes. The electrodes are connected to the power supply through an electrode auxiliary system, which includes an electrode holding structure, an electrode lifting mechanism, and a pressing and releasing mechanism.

[0003] A search revealed that the announcement number CN107541788B, entitled "An Integrated Electrode Lifting Mechanism for a Single Crystal Silicon Growth Furnace," includes four guide columns fixedly installed between the furnace chassis and the frame of the single crystal furnace, and a substrate mounted on the four guide columns that can move up and down along the guide columns. Research and analysis showed that by using a servo motor to simultaneously drive the lifting of two main electrodes and two auxiliary supports, the cost of the entire electrode lifting mechanism for the single crystal silicon growth furnace is reduced. However, it still has the following drawbacks to some extent.

[0004] For example, if multiple drive mechanisms are needed to raise and lower the electrodes, the energy required for driving is large, resulting in wasted costs. When a single electrode needs to be used, the other electrodes will obstruct it, affecting the normal operation of the electrode and making it inconvenient for the operator. In order to solve the above technical problems, we have designed an automatic lifting and adjusting mechanism for four-electrode submerged arc furnace electrodes. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic lifting and adjusting mechanism for electrodes in a four-electrode submerged arc furnace. It has the advantages of lifting and lowering individual electrodes and saving energy. It solves the problems of needing to use multiple drive mechanisms to lift and lower electrodes, which requires a large amount of energy and results in wasted costs. When a single electrode needs to be used, the other electrodes will obstruct it and affect the normal operation of that electrode.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic electrode lifting and adjusting mechanism for a four-electrode submerged arc furnace, comprising a base plate, with double-brake casters fixedly installed at the four corners of the bottom of the base plate, a fixed cylinder fixedly installed at the center of the top of the base plate, and a lifting and adjusting assembly fixedly installed inside the fixed cylinder. The lifting and adjusting assembly includes a motor, which is fixedly installed at the center of the bottom of the base plate. The top of the output shaft of the motor penetrates into the inner cavity of the fixed cylinder and is fixedly installed with a threaded rod. A lifting plate is threadedly fitted onto the surface of the threaded rod, a support plate is fixedly installed on the front side of the lifting plate, and a vertical plate is fixedly welded to the top of the support plate. A limit ring is fitted onto the top of the surface of the vertical plate. A rotating assembly is fixedly installed on the outer ring of the top of the base plate. The rotating assembly includes a rotating seat, which is rotatably mounted on the outer ring of the top of the base plate via a rotating shaft. A gear ring is fixedly sleeved on the outer surface of the rotating seat. Motor 2 is embedded on both the front and rear sides of the top of the base plate. A gear that meshes with the gear ring is fixedly sleeved on the output shaft of the motor 2. A placement cavity is opened on the top of the rotating seat. A placement assembly is arranged inside the placement cavity. The placement assembly includes a placement seat, which is placed inside the placement cavity. A placement groove is opened on the top of the placement seat, and a receiving groove is opened on the bottom of the placement seat. A placement block is fixedly welded to the top of the outer ring of the placement seat, and an electrode body is placed on the top of the placement groove.

[0007] Preferably, cylinders are embedded in both the left and right sides of the base plate, and a gripping plate is fixedly welded to the bottom of the telescopic end of the cylinder, and a number of gripping teeth are welded to the bottom of the gripping plate.

[0008] Preferably, a limiting baffle is fixedly fitted on the top of the surface of the vertical plate, the bottom of the limiting ring is placed on the top of the limiting baffle, and the size of the limiting ring and the size of the placement groove are adapted to the size of the electrode body.

[0009] Preferably, sliding plates are fixedly welded to both the left and right sides of the lifting plate, sliding holes for sliding of the sliding plates are opened on both the left and right sides of the fixed cylinder, and a through hole for moving of the support plate is opened on the front side of the fixed cylinder.

[0010] Preferably, the size of the receiving groove matches the size of the support plate, and a groove adapted to the placement block is provided at the top edge of the placement cavity.

[0011] Preferably, the first motor is a stepper motor, the first motor rotates at an angle of °, and the support plate is located directly below the placement seat.

[0012] Preferably, the interior of the rotating seat is a hollow structure, and the support plate is located in the inner cavity of the rotating seat and does not contact the inner wall of the rotating seat.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model utilizes a motor to drive a threaded rod to rotate. Through the threaded connection between the lifting plate and the threaded rod, the support plate is moved upward to below the placement seat. The electrode body is limited to the surface of the vertical plate by a limiting ring. Then, the support plate drives the placement seat and the electrode body to lift and lower. The entire process only lifts and lowers one electrode body, and it will not be affected by other electrodes during the operation, thus improving the convenience of operation for workers.

[0015] 2. This utility model uses a motor to drive a gear to rotate, which in turn drives the rotating seat to rotate through meshing with the gear ring. This allows the electrode body placed on the top of the mounting base to rotate autonomously to the top of the support plate, thereby enabling the lifting and lowering of different electrode bodies to achieve an automatic adjustment effect.

[0022] Please see Figures 1-5An automatic electrode lifting and adjusting mechanism for a four-electrode submerged arc furnace includes a base plate 1. Double-brake casters 8 are fixedly installed at the four corners of the bottom of the base plate 1. These casters allow for easy movement of the device to different positions for lifting and adjusting the electrode body 4. A fixed cylinder 6 is fixedly installed at the center of the top of the base plate 1. The fixed cylinder 6 protects the threaded rod 52 and limits the movement of the lifting plate 53, preventing rotation during movement. A lifting and adjusting assembly 5 is fixedly installed inside the fixed cylinder 6. The lifting and adjusting assembly 5 includes a motor 51, which is fixedly installed at the center of the bottom of the base plate 1. The top of the output shaft of the motor 51 extends through the inner cavity of the fixed cylinder 6 and is fixedly installed with the threaded rod 52. The surface of the threaded rod 52 is threaded with the lifting plate 53. A support plate 54 is fixedly installed on the front side of the lifting plate 53. A vertical plate 55 is fixedly welded to the top of the support plate 54. A limit ring 56 is fitted onto the top of the surface of the vertical plate 55. The limit ring 56 allows for easy adjustment of the electrode body. The electrode body 4 is bound to the surface of the vertical plate 55 to prevent it from shaking during the lifting and lowering adjustment. A rotating component 3 is fixedly installed on the outer ring of the top of the base plate 1. The rotating component 3 includes a rotating seat 31. The rotating seat 31 is rotatably installed on the outer ring of the top of the base plate 1 via a rotating shaft. A gear ring 32 is fixedly sleeved on the outer surface of the rotating seat 31. Motor 2 33 is embedded on both the front and rear sides of the top of the base plate 1. A gear 34 that meshes with the gear ring 32 is fixedly sleeved on the output shaft of the motor 2 33. A placement cavity 35 is opened on the top of the rotating seat 31. A placement component 9 is set inside the placement cavity 35. The placement component 9 includes a placement seat 91. The placement seat 91 is placed inside the placement cavity 35. A placement groove 93 is opened on the top of the placement seat 91. A receiving groove 94 is opened on the bottom of the placement seat 91. By setting the receiving groove 94, the support plate 54 can be accommodated so that the support plate 54 will not shake during the process of driving the placement seat 91 to rise. A placement block 92 is fixedly welded to the top of the outer ring of the placement seat 91. The electrode body 4 is placed on the top of the placement groove 93.

[0023] Please see Figure 1 and Figure 2 Cylinders 2 are embedded in both the left and right sides of the base plate 1. A gripping plate 7 is fixedly welded to the bottom of the telescopic end of the cylinder 2. Several gripping teeth are welded to the bottom of the gripping plate 7. By setting the gripping plate 7 and the gripping teeth, the friction between the device and the ground can be increased, the stability of the device when it is fixed can be improved, and the shaking can be avoided.

[0024] Please see Figure 4 A limiting baffle is fixedly fitted on the top of the surface of the vertical plate 55, and the bottom of the limiting ring 56 is placed on the top of the limiting baffle. The size of the limiting ring 56 and the size of the placement groove 93 are both adapted to the size of the electrode body 4.

[0025] Please see Figure 4Slide plates are fixedly welded to both sides of the lifting plate 53. Slide holes for sliding of the slide plates are opened on both sides of the fixed cylinder 6. By setting the slide holes, the slide plates can move together and can limit the movement of the lifting plate 53 to prevent it from rotating during the movement. A through hole for the support plate 54 to move is opened on the front side of the fixed cylinder 6.

[0026] Please see Figure 5 The size of the receiving groove 94 matches the size of the support plate 54. A groove adapted to the placement block 92 is provided at the top edge of the placement cavity 35. By setting the groove, the placement seat 91 can be limited so that it can be stably installed inside the placement cavity 35 without rotating.

[0027] Please see Figure 4 Motor 51 is a stepper motor. The angle of each rotation of motor 51 is 45°. The support plate 54 is located directly below the placement base 91.

[0028] Please see Figure 3 The interior of the rotating seat 31 is a hollow structure, and the support plate 54 is located in the inner cavity of the rotating seat 31 and does not contact the inner wall of the rotating seat 31.

[0029] In use, the device is pushed to the desired position by the double-brake casters 8 at the bottom of the base plate 1, and then the double-brake casters 8 are braked. The cylinder 2 is started, and its telescopic end drives the gripping plate 7 to descend, so that the gripping teeth at the bottom of the plate make contact with the ground for stable fixation. The second motor 33 drives the gear 34 to rotate, and through its meshing with the gear ring 32, it drives the rotating seat 31 to rotate, so that the electrode body 4 placed on the top placement seat 91 can rotate autonomously to the top of the support plate 54. Then, the first motor 51 is started, and the first motor 51 drives the threaded rod 52 to rotate. Through the threaded connection between the lifting plate 53 and the threaded rod 52, the support plate 54 is moved upward to the bottom of the placement seat 91. Then, the limiting ring 56 is fitted onto the surface of the vertical plate 55 to limit the electrode body 4 to the surface of the vertical plate 55. Then, the support plate 54 drives the placement seat 91 and the electrode body 4 to lift and lower. The whole process only lifts and lowers one electrode body 4, without affecting the operation of other electrode bodies 4.

[0030] In summary, this four-electrode submerged arc furnace electrode automatic lifting and adjusting mechanism, through the cooperation of the base plate 1, cylinder 2, rotating component 3, electrode body 4, lifting and adjusting component 5, gripping plate 7, double brake casters 8, and placement component 9, solves the problems of needing to use multiple drive mechanisms to lift and lower the electrode, requiring a large amount of energy for driving, resulting in wasted costs, and when only a single electrode needs to be used, the other electrodes will obstruct it and affect the normal operation of that electrode.
