Description

Technical Field

[0001] This disclosure relates to the field of graphite electrode technology for electric furnaces, and more particularly to a device for adjusting the verticality of graphite electrodes. Background Technology

[0002] Large titanium slag electric arc furnaces use graphite electrodes with significant diameter, length, and weight. The verticality of the electrode clamp is crucial for the electrode pressing and releasing process. If the clamp is misaligned, the graphite electrode can easily break and fall into the furnace after tightening, causing a shutdown. Furthermore, each instance of graphite electrode breakage is time-consuming, labor-intensive for maintenance personnel, and impacts titanium slag production. Moreover, graphite electrode breakage significantly reduces furnace operating rates, requiring additional maintenance time, increasing the workload of maintenance personnel, and further reducing titanium slag production, ultimately resulting in economic and social losses.

[0003] Therefore, how to adjust the verticality of the graphite electrode has become an urgent problem to be solved. Utility Model Content

[0004] In view of this, the present invention provides a device for adjusting the verticality of a graphite electrode to solve the technical problem of how to adjust the verticality of a graphite electrode.

[0005] To solve the above-mentioned technical problems, in a first aspect, the present invention provides a device for adjusting the verticality of a graphite electrode. The device includes a graphite electrode, a brake shoe, and a pressure-applying part. The inner side of the brake shoe is in contact with the graphite electrode, and the outer side of the brake shoe is in contact with the pressure-applying part. The pressure-applying part applies pressure to the brake shoe to make the brake shoe hold the graphite electrode tightly.

[0006] In conjunction with the first aspect, in one possible implementation of the first aspect, the inner side of the brake shoe is in contact with one of the surfaces of the outer peripheral facade of the graphite electrode.

[0007] In conjunction with the first aspect, in one possible implementation of the first aspect, the brake shoes and corresponding pressure-applying parts are used in groups, and the opposite faces on the outer peripheral surface of the graphite electrode have corresponding brake shoes and pressure-applying parts used in groups.

[0008] In conjunction with the first aspect, in one possible implementation of the first aspect, the brake shoes and the corresponding pressure-applying parts are used in groups, and the outer peripheral surfaces of the graphite electrode all have corresponding brake shoes and pressure-applying parts used in groups.

[0009] In conjunction with the first aspect, in one possible implementation of the first aspect, the brake shoe has at least one groove, and the pressure-applying portion includes at least one top block that engages with the groove.

[0010] In conjunction with the first aspect, in one possible implementation of the first aspect, at least one groove is a circular groove and at least one top block is a circular top block.

[0011] In conjunction with the first aspect, in one possible implementation of the first aspect, a pressure plate and a connecting screw are used, wherein the pressure plate is used to fix at least one top block, and the connecting screw is used to apply pressure to the brake shoe.

[0012] In conjunction with the first aspect, in one possible implementation of the first aspect, the brake shoe is also used to slide along the outer periphery of the graphite electrode under the action of the pressure part.

[0013] Through the above technical solution, this disclosure provides a device for adjusting the verticality of a graphite electrode. The device includes a graphite electrode, a brake shoe, and a pressure-applying part. The inner side of the brake shoe contacts the graphite electrode, and the outer side of the brake shoe contacts the pressure-applying part. The pressure-applying part applies pressure to the brake shoe, causing the brake shoe to grip the graphite electrode. During this process, the pressure applied by the pressure-applying part causes the brake shoe to adhere to the graphite electrode under the applied pressure, thus completing the verticality adjustment of the graphite electrode. This reduces the risk of graphite electrode breakage after gripping, effectively reducing graphite electrode breakage failures, improving the electric furnace operating rate, reducing maintenance time, alleviating the labor intensity of maintenance personnel, and increasing the output of titanium slag in the electric furnace, thereby creating significant economic and social benefits.

[0027] like Figure 1 , Figure 2 As shown, this utility model discloses a device for adjusting the verticality of a graphite electrode. The device includes a graphite electrode 1, a brake shoe 2, and a pressure-applying part. The inner side of the brake shoe 2 is in contact with the graphite electrode 1, and the outer side of the brake shoe 2 is in contact with the pressure-applying part. The pressure-applying part applies pressure to the brake shoe 2, causing the brake shoe 2 to grip the graphite electrode 1 tightly.

[0028] Specifically, the inner side of the brake shoe 2 being in contact with the graphite electrode 1 means that the brake shoe 2 is in contact with one surface of the outer peripheral surface of the graphite electrode 1, and after the pressure is applied to the brake shoe 2 by the pressure-applying part, the brake shoe 2 clamps the graphite electrode 1. The outer side of the brake shoe 2 being in contact with the pressure-applying part means that the pressure-applying part is connected to the outer side of the brake shoe 2, and when pressure is applied to the pressure-applying part, the pressure is transmitted to the brake shoe 2.

[0029] Specifically, after the pressure-applying part applies pressure to the brake shoe 2, the pressure is transmitted from the pressure-applying part to the brake shoe 2 and acts on the graphite electrode 1 that is in contact with the brake shoe 2. This causes a force acting from the outside to the inside of the graphite electrode 1 to be applied to the side of the brake shoe 2 that is in contact with the graphite electrode 1, thereby adjusting the perpendicularity of the contact position between the inner side of the brake shoe 2 and the graphite electrode 1 under the action of the force.

[0030] Through the above technical solution, this disclosure provides a device for adjusting the verticality of a graphite electrode. The device includes a graphite electrode, a brake shoe, and a pressure-applying part. The inner side of the brake shoe contacts the graphite electrode, and the outer side of the brake shoe contacts the pressure-applying part. The pressure-applying part applies pressure to the brake shoe, causing the brake shoe to grip the graphite electrode. During this process, the pressure applied by the pressure-applying part causes the brake shoe to adhere to the graphite electrode under the applied pressure, thus completing the verticality adjustment of the graphite electrode. This reduces the risk of graphite electrode breakage after gripping, effectively reducing graphite electrode breakage failures, improving the electric furnace operating rate, reducing maintenance time, alleviating the labor intensity of maintenance personnel, and increasing the output of titanium slag in the electric furnace, thereby creating significant economic and social benefits.

[0031] In some alternative embodiments, the inner side of the brake shoe 2 is in contact with one of the surfaces of the outer peripheral surface of the graphite electrode 1.

[0032] Specifically, the outer peripheral surface of the graphite electrode 1 refers to the outer surface of the graphite electrode 1 in the direction perpendicular to the ground. The shape of the graphite electrode 1 can be set according to the actual working conditions, and this embodiment does not impose a specific limitation on it. For example, if the graphite electrode 1 is square in the top view, then the outer peripheral surface of the graphite electrode 1 refers to the four outer surfaces of the graphite electrode 1 perpendicular to the ground; similarly, if the graphite electrode 1 is hexagonal in the top view, then the outer peripheral surface of the graphite electrode 1 refers to the six outer surfaces of the graphite electrode 1 perpendicular to the ground, and so on, without further elaboration.

[0033] In some alternative embodiments, the brake shoe 2 and the corresponding pressure-applying part are used in groups, and the opposite surfaces on the outer peripheral surface of the graphite electrode 1 have corresponding brake shoes 2 and pressure-applying parts used in groups.

[0034] Specifically, the use of brake pads 2 and corresponding pressure-applying parts in groups means that each brake pad 2 in contact with the outer peripheral surface of the graphite electrode 1 has a corresponding pressure-applying part on its outer side, so that the corresponding pressure-applying part can apply pressure to the brake pad 2, causing the brake pad 2 on that surface to grip the graphite electrode 1 on the corresponding surface.

[0035] Specifically, the fact that the opposite surfaces of the outer peripheral surface of the graphite electrode 1 each have corresponding sets of brake shoes 2 and pressure-applying parts means that the outer peripheral surface of the graphite electrode 1 has brake shoes 2 arranged opposite to each other, and pressure-applying parts corresponding to the brake shoes 2, so that the pressure-applying parts apply pressure to the brake shoes 2, thereby applying a force from the outer surface to the inside on the opposite outer peripheral surface of the graphite electrode 1. Since the brake shoes 2 are set in relative positions on the outer peripheral surface of the graphite electrode 1, each applied force acts on the inside of the graphite electrode 1, and the directions of the forces are opposite, making the verticality adjustment of the graphite electrode more obvious than the force applied on one side. Thus, the verticality adjustment of the contact position between the inner side of the brake shoes 2 and the graphite electrode 1 is completed under the action of the force. For example, if graphite electrode 1 is a cuboid, and its top surface is a quadrilateral when viewed from above, with the numbers a, b, c, and d in a clockwise direction, then the opposite faces on the outer perimeter of graphite electrode 1 are either a and c or b and d. Similarly, if the top surface of graphite electrode 1 is a hexagon when viewed from above, with the numbers a, b, c, d, e, and f in a clockwise direction, then the opposite faces on the outer perimeter of graphite electrode 1 are either a and d or b and e or c and f or a, c, e or b, d, f, and so on.

[0036] In some alternative embodiments, the brake shoe 2 and the corresponding pressure-applying part are used in groups, and the outer peripheral surface of the graphite electrode 1 has the corresponding brake shoe 2 and pressure-applying part used in groups.

[0037] Specifically, the outer periphery of the graphite electrode 1 is provided with corresponding sets of brake shoes 2 and pressure-applying parts. This means that each surface of the outer periphery of the graphite electrode 1 is provided with a brake shoe 2 and a pressure-applying part corresponding to the brake shoe 2, so that the pressure-applying part applies pressure to the brake shoe 2, thereby applying a force from the outer surface to the inside on each outer periphery of the graphite electrode 1. Since the brake shoes 2 are provided on each surface of the outer periphery of the graphite electrode 1, each applied force acts on the inside of the graphite electrode 1, making the verticality adjustment of the graphite electrode more obvious than the force applied to a single side or opposite side. Thus, the verticality adjustment of the contact position between the inner side of the brake shoe 2 and the graphite electrode 1 is completed under the action of the force.

[0038] In some alternative embodiments, the brake shoe 2 has at least one groove, and the pressure-applying portion includes at least one top block 4, which engages with the groove.

[0039] Specifically, such as Figure 1 , Figure 2 As shown, the brake shoe 2 has at least one groove, and the pressure-applying part includes at least one top block 4. The top block 4 engages with the groove, and pressure is applied to the brake shoe 2 by the pressure-applying part. The force is transmitted to the brake shoe 2 through the engaged groove via the at least one top block 4, thereby causing the brake shoe 2 to grip the graphite electrode 1. It should be understood that the number of grooves and top blocks 4 on the brake shoe 2 includes, but is not limited to, those shown in the figure, as long as the top block 4 engages with the groove to transmit force. Furthermore, when there are multiple grooves and top blocks 4, the force exerted by the brake shoe 2 on the graphite electrode 1 from the outer surface to the inner surface should also be multiple, making the perpendicularity adjustment of the graphite electrode at that position more significant than the force applied by the engagement of a single groove and top block. This allows the perpendicularity adjustment of the contact position between the inner side of the brake shoe 2 and the graphite electrode 1 to be completed under the action of force.

[0040] In some alternative embodiments, at least one groove is a circular groove, and at least one top block 4 is a circular top block.

[0041] Specifically, such as Figure 1 , Figure 2 As shown, at least one groove is a circular groove, and the corresponding top block 4 is a circular top block. It should be understood that the groove can also be a square groove or a groove of other shapes, and the corresponding top block can be a square top block or a top block of other shapes. This embodiment does not specifically limit this, and it can be set according to the actual working conditions.

[0042] Specifically, when at least one groove is a circular groove and at least one top block 4 is a circular top block, in subsequent embodiments, the brake shoe 2 is more conducive to sliding along the outer periphery of the graphite electrode 1 under the action of the pressure part. Therefore, it is usually chosen that the groove is a circular groove and the top block 4 is a circular top block.

[0043] In some alternative embodiments, the pressure application part further includes a pressure plate 3 and a connecting screw 5, wherein the pressure plate 3 is used to fix at least one top block 4, and the connecting screw 5 is used to apply pressure to the brake shoe 2 through the connecting screw 5.

[0044] Specifically, such as Figure 1 , Figure 2 As shown, the pressure plate 3 is used to fix at least one top block 4 to ensure the fit between the top block 4 and the corresponding groove, and to prevent the top block 4 from sliding in the corresponding groove when there is no external force.

[0045] Specifically, the connecting screw 5 is connected to the top block 4, and the connecting screw 5 is designed to facilitate the pressure application part to the brake shoe 2.

[0046] In some alternative embodiments, the brake shoe 2 is also used to slide along the outer peripheral surface of the graphite electrode 1 under the action of the pressure part.

[0047] Specifically, the sliding of the brake shoe 2 along the outer periphery of the graphite electrode 1 means that the brake shoe 2 slides from one end of the graphite electrode 1 to the other end of the graphite electrode 1, and during this process, the pressure-applying part continues to apply pressure to the brake shoe 2, thereby completing the verticality adjustment of each position from one end of the graphite electrode 1 to the other end of the graphite electrode 1, that is, completing the overall verticality adjustment of the graphite electrode 1.

[0048] The method for adjusting the perpendicularity of a graphite electrode using the aforementioned graphite electrode perpendicularity adjustment device is as follows: Figure 3 As shown. The method includes the following steps:

[0049] S101. In response to the graphite electrode verticality adjustment command, the brake shoe and pressure application part are installed to one end of the graphite electrode to determine the installation position.

[0050] Specifically, the brake shoe and pressure-applying part are installed to one end of the graphite electrode. Determining the installation position means installing the brake shoe and pressure-applying part to one end of the outer peripheral surface of the graphite electrode, such as the top or bottom end, and using the corresponding position as the installation location. The brake shoe and corresponding pressure-applying part are used in sets, and the installation location includes one surface, opposite surfaces, or each surface of the outer peripheral surface of the graphite electrode. For details, please refer to the relevant descriptions in the above embodiments, which will not be repeated here.

[0051] S102. Based on the installation position, the pressure part and the brake shoe are used to make the brake shoe hold the graphite electrode tightly, thus completing the first verticality adjustment of the graphite electrode.

[0052] Specifically, based on the installation position, the pressure application part and the brake shoe are used to make the brake shoe grip the graphite electrode. This means that pressure is applied to the brake shoe by the pressure application part at the installation position, so that the brake shoe grips the graphite electrode. For details, please refer to the relevant descriptions in the above embodiments, which will not be repeated here.

[0053] Through the above technical solution, this disclosure provides an apparatus and method for adjusting the verticality of a graphite electrode. The method includes: responding to a graphite electrode verticality adjustment command, installing a brake shoe and a pressure-applying part to one end of the graphite electrode to determine the installation position; based on the installation position, using the pressure-applying part and the brake shoe, causing the brake shoe to grip the graphite electrode tightly, completing the initial verticality adjustment of the graphite electrode. During this process, pressure is applied to the brake shoe by the pressure-applying part, thereby causing the brake shoe to adhere to the graphite electrode under the applied pressure, and completing the verticality adjustment of the graphite electrode under the action of the brake shoe. This reduces the risk of graphite electrode breakage after gripping, effectively reducing graphite electrode breakage failures, improving the electric furnace operating rate, reducing maintenance time, alleviating the labor intensity of maintenance personnel, and increasing the output of titanium slag in the electric furnace, thereby creating significant economic and social benefits.
