Description

Technical Field

[0001] The utility model belongs to the technical field of electrolytic aluminum, and particularly relates to a separating and drawing device for cathode carbon blocks and square steel. Background Technique

[0002] Electrolytic aluminum refers to the process of producing aluminum metal through electrolysis. Cathode carbon blocks are an important material used in this process and are used as cathodes in electrolytic cells.

[0003] Conductive square steel is arranged on the cathode carbon block. The installation method of the cathode carbon block and the square steel generally adopts phosphor cast iron casting, that is, grooves are opened on the upper end surface of the cathode carbon block, then the square steel is placed in the grooves of the cathode carbon block, and phosphor cast iron is cast, so as to firmly connect the cathode carbon block and the square steel into one body. During this casting process, the positioning requirements of the cathode carbon block in the grooves are very high, and it is necessary to ensure that the distances from both sides of the square steel to the grooves of the cathode carbon block are the same. Since the position of the square steel is judged by human eyes in many cases during the positioning process of the square steel, or the position of the square steel changes during the casting process, the position dimensions of the cast square steel and the cathode carbon block will eventually be unqualified. Once the casting is unqualified, it is necessary to separate the cast cathode carbon block and the square steel, take out the square steel, remove the phosphor cast iron on the outside of the square steel, and clean the grooves of the cathode carbon block, and then carry out re-casting. At present, there is no related technology to achieve this function. Content of the Utility Model

[0004] Aiming at the technical problems existing in the background technique, the utility model provides a separating and drawing device for cathode carbon blocks and square steel.

[0005] To achieve the above purpose, the technical solution provided by the utility model is as follows:

[0006] A separating and drawing device for cathode carbon blocks and square steel includes a frame. One side of the frame abuts against the side surface of the cathode carbon block, and a drawing mechanism is arranged at the other end of the frame. The drawing mechanism is connected with a clamping assembly, and the clamping assembly is used for clamping and fixing on the square steel.

A second cross bar is disposed above the first cross bar, and both ends of the second cross bar are respectively fixedly connected to the first vertical bar and the second vertical bar. The bottom sides of the two first vertical bars are connected by a contact block, the contact block is in contact with the cathode carbon block, and the upper end surface of the contact block is lower than the lower end surface of the square steel.

[0009] Optionally, the bottom ends of the two second vertical bars are connected by a first longitudinal bar, and the upper ends of the two second vertical bars are connected by a second longitudinal bar. A hook portion is disposed at the upper end of the second longitudinal bar.

[0010] Optionally, a plurality of rollers are disposed between the two second cross bars, and the upper end surfaces of the rollers are flush with the lower end surface of the square steel.

[0011] Optionally, at least one roller is disposed on the second cross bar close to the cathode carbon block, and a plurality of rollers are evenly distributed on the second cross bar away from the cathode carbon block.

[0013] Optionally, a limiting plate is disposed at the upper end of the clamping plate, and the limiting plates of the two clamping plates support on the upper end surface of the square steel, so that the clamping assembly is supported on the square steel.

[0014] Optionally, two tension bars are welded to the upper end of the square steel at a fixed distance apart, and the tension bars are disposed in the gaps between the limiting plate and the clamping plate.

[0015] The utility model has the following advantages and beneficial effects:

[0016] In the present utility model, especially in the scenario of casting cathode carbon blocks and square steel with phosphorus cast iron, when the casting is unqualified, by using the separation and drawing device of the present application, one side of the frame is abutted against the side of the cathode carbon block, and then the drawing mechanism at the other end of the frame is operated.

Detailed implementation manners

[0031] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model.

[0032] Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the present utility model to be protected, but merely represents selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0033] Embodiment

[0034] As Figure 1 , Figure 2 shown, a connection structure between a square steel 13 and a cathode carbon block 1. Specifically, a plurality of slots 11 are formed in the upper section of the cathode carbon block 1. The slots 11 are in the shape of dovetail grooves, that is, the upper opening is large and the lower opening is small. After the square steel 13 is arranged in the slots 11, there is a certain distance between the bottom side and both sides of the square steel 13 and the slots 11. Phosphor cast iron 12 is cast in the slots 11, so as to firmly connect the square steel 13 and the cathode carbon block 1 into one body. With the dovetail groove-shaped slots 11, the square steel 13 will not be separated from the cathode carbon block 1, that is, when a force is applied in the B direction shown in Figure 2 , the square steel 13 will not be separated from the cathode carbon block 1. The phosphor cast iron 12 connects the square steel 13 and the cathode carbon block 1. When the casting is unqualified, the square steel 13 needs to be pulled out laterally (that is, a force is applied in the Figure 1 A direction), and then the square steel 13 can be separated from the cathode carbon block 1.

[0035] Since the connection strength between the square steel 13 and the phosphorus cast iron 12 is greater than the connection strength between the phosphorus cast iron 12 and the cathode carbon block 1, which depends on the connection strength between the phosphorus cast iron 12 and different materials, when pulling the square steel 13, the phosphorus cast iron 12 on the surface of the square steel 13 will be pulled out together from the cathode carbon block 1.

[0036] As Figure 3 - 13 shown, a separating and pulling device for a cathode carbon block and a square steel includes a frame 2. One side of the frame 2 abuts against the side surface of the cathode carbon block 1. A pulling mechanism is arranged at the other end of the frame 2. The pulling mechanism is connected with a clamping assembly 5. The clamping assembly 5 is used for clamping and fixing on the square steel 13. The pulling mechanism can pull the clamping assembly 5 to move away from the cathode carbon block 1 so that the square steel 13 and the cathode carbon block 1 are separated. This device can pull out the square steel 13 in the case where the casting of the cathode carbon block 1 and the square steel 13 is unqualified, so as to facilitate re-casting, ensure the assembly accuracy of the cathode carbon block 1 and the square steel 13, and avoid the generation of waste due to unqualified casting, that is, the unqualified casting causes the cathode carbon block 1 and the square steel 13 to be scrapped, thereby greatly increasing the cost.

[0037] In the present utility model, no specific limitation is imposed on the pulling device. For example, a hydraulic cylinder can be used to achieve hydraulic pulling. As a preferred setting, the pulling mechanism is a manual hoist 3, and the pulling chain 4 of the manual hoist 3 is connected with the clamping assembly 5. The manual hoist 3 adopts the existing technology and no specific design improvement is made. By directly using the manual hoist 3, fixing one end of the manual hoist 3 on the frame 2 and connecting the pulling chain 4 of the manual hoist 3 with the clamping assembly 5, the pulling operation can be quickly realized.

[0038] In the present utility model, the frame 2 includes a first cross bar 21, a second cross bar 24, a first longitudinal bar 28, a second longitudinal bar 25, a first vertical bar 22 and a second vertical bar 23. The two ends of the two first cross bars 21 are respectively connected and fixed with the first vertical bar 22 and the second vertical bar 23. A second cross bar 24 is arranged above the first cross bar 21. The two ends of the second cross bar 24 are respectively fixedly connected with the first vertical bar 22 and the second vertical bar 23. The bottom sides of the two first vertical bars 22 are connected by an abutting block 27, and the abutting block 27 abuts against the cathode carbon block 1. The upper end surface of the abutting block 27 is lower than the lower end surface of the square steel 13. With such a design, the contact area with the cathode carbon block 1 is increased through the abutting block 27 to achieve abutting, and at the same time, the square steel 13 can be pulled out from the upper part of the abutting block 27 without affecting the pulling out of the square steel 13.

[0039] Furthermore, the bottom ends of the two second vertical bars 23 are connected by a first longitudinal bar 28, the upper ends of the two second vertical bars 23 are connected by a second longitudinal bar 25, and a hook portion 26 is arranged at the upper end of the second longitudinal bar 25. The hook of the manual hoist 3 can be arranged on the hook portion 26, so as to realize the fixing of the manual hoist 3.

[0040] Further, a number of rollers 29 are arranged between the two second cross bars 24, and the upper end surfaces of the rollers 29 are flush with the lower end surface of the square steel 13. Since the square steel 13 is very heavy, when drawing, once half of the square steel 13 is separated from the cathode carbon block 1, the square steel 13 will naturally drop. Therefore, the rollers 29 are provided so that when the square steel 13 is pulled out, it can be supported on the rollers 29. At the same time, when drawing, the square steel 13 can roll on the rollers 29 to achieve labor-saving drawing operation.

[0041] Furthermore, at least one roller 29 is arranged on the second cross bar 24 close to the cathode carbon block 1, and a number of rollers 29 are evenly distributed on the second cross bar 24 far from the cathode carbon block 1. Such a design is because the length of the square steel 13 is long enough, so theoretically the length of the frame 2 is also long enough, so more rollers 29 need to be arranged. In order to reduce the number of rollers 29, the number of rollers 29 arranged on the side close to the cathode carbon block 1 is very small, because when the square steel 13 starts to be pulled out, the square steel 13 is supported on the cathode carbon block 1, so the rollers 29 on this side are not needed for support; however, once half or more of the square steel 13 is pulled out, most of the force of the square steel 13 will act on the rollers 29. Therefore, more rollers 29 are arranged on the side of the frame 2 far from the cathode carbon block 1 to support the square steel 13 to ensure that the square steel 13 can be smoothly drawn. When the square steel 13 is completely separated from the cathode carbon block 1, the end of the square steel 13 will be supported on the rollers 29 close to the cathode carbon block 1, so that the entire square steel 13 is pulled out and placed on the rollers 29. Such a design can smoothly draw the square steel 13, while reducing the number of rollers 29 and facilitating the transfer of the square steel 13. When the square steel 13 is drawn onto the rollers 29, the next hoisting operation can be carried out.

[0042] As Figure 8 - 13 shown, in the present utility model, the clamping assembly 5 includes clamping plates 51. The clamping plates 51 have a certain weight. There are two clamping plates 51, and a number of claw nails 511 are evenly distributed on the clamping surfaces of the clamping plates 51; a first connecting rod 513 extends obliquely from one side of the clamping plate 51. The number of the first connecting rods 513 is two. The middle parts of the first connecting rods 513 of the two clamping plates 51 are rotationally connected through a first rotating shaft 52. The ends of the first connecting rods 513 of the two clamping plates 51 are respectively rotationally connected with second connecting rods 53 through a second rotating shaft 54. The other ends of the two second connecting rods 53 are rotationally connected through a third rotating shaft 55, thus forming a parallelogram link structure; a pull ring 56 is arranged on the third rotating shaft 55, and the pulling chain 4 of the manual hoist 3 is connected with the pull ring 56. In this structure, when the pull ring 56 is pulled forcefully (such as Figure 13 applying force in the arrow direction shown), it will force the two clamping plates 51 to approach each other, thereby clamping the square steel 13, and the greater the pulling force, the greater the clamping force, so as to achieve stable clamping and fixing.

[0043] Further, a limiting plate 512 is provided at the upper end of the clamping plate 51. The limiting plates 512 of the two clamping plates 51 support on the upper end surface of the square steel 13, so that the clamping assembly 5 is supported on the square steel 13, facilitating the installation of the clamping assembly 5.

[0044] Further, in order to enhance the stability and firmness of clamping, two tension bars 14 are welded to the upper end of the square steel 13 at a fixed distance apart. The tension bars 14 are arranged in the gaps between the limiting plate 512 and the clamping plate 51 (as Figure 13 shown). With such a design, when installing the clamping assembly 5, the two clamping plates 51 are respectively arranged on both sides of the square steel 13, the limiting plate 512 is arranged on the upper end surface of the square steel 13, and then the pull ring 56 is gradually pulled, so that the two clamping plates 51 are slowly clamped. And as the pulling force increases, the clamping force also increases. Moreover, the limiting plate 512 and the tension bar 14 are clamped and limited, which can further prevent the clamping assembly 5 from retreating unstably when starting to apply force. With the cooperation of the tension bar 14 for positioning, the clamping force of the clamping plate 51 can be further enhanced. However, if the tension bar 14 is set alone, the welding strength of the tension bar 14 is not enough. When only applying force to the tension bar 14, the tension bar 14 and the square steel 13 will break and separate. Therefore, with the limitation of the tension bar 14, the clamping assembly 5 is gradually clamped to the square steel 13, and with the clamping of the clamping plate 51, the two work together to firmly clamp the square steel 13 and pull the square steel 13 and the cathode carbon block 1 apart.

[0045] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
