Description

Technical Field

[0001] The utility model relates to the technical field of repair tools, in particular to an auxiliary device for repairing the outer shell of an aluminum smelting crucible. Background Technique

[0002] During the production of high-purity aluminum, the outer shell of the crucible operates in an environment of 800 °C high temperature and 7.5 MPA pressure. The bottom of the outer shell is extremely prone to cracking, distortion and deformation. When the refining furnace is operating, if the inner liner of the graphite crucible ruptures and the molten aluminum leaks, it will leak into the refining furnace from the outer shell of the crucible, resulting in damage to the heating belt and causing equipment failures. When the bottom of the outer shell of the crucible is deformed, it is unstable when placed upright and is particularly prone to tipping over and causing safety accidents. Therefore, it is necessary to cut and weld the deformed part of the outer shell of the crucible to complete the repair of the outer shell, increase the service life of the outer shell of the crucible, effectively prevent equipment failures caused by the sliding of molten aluminum when the inner liner ruptures, and eliminate the tipping safety hazard at the same time. However, due to the cylindrical shape of the outer shell of the crucible itself and the hemispherical shape of the bottom, it is very difficult to ensure that it is consistent with the original shape during the repair process.

[0003] Therefore, it is very necessary to design an auxiliary device for repairing the outer shell of an aluminum smelting crucible. Content of the Utility Model

Detailed Embodiment

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4 , the present utility model provides a technical solution: an auxiliary device for repairing the outer shell of an aluminum smelting crucible, including a carrier ring 1, a fixed ring 2 and a moving ring 3. The fixed ring 2 is fixedly installed on the inner edge of the upper surface of the carrier ring 1, the moving ring 3 is rotatably installed on the inner edge of the fixed ring 2, a plurality of circumferentially distributed positioning blocks 4 are integrally formed on the inner wall of the moving ring 3, an outer ball 5 is rotatably installed on the inclined surface of the positioning block 4, a cross beam frame 6 is fixedly installed at the bottom end of the inner diameter of the carrier ring 1, and a fixed measuring instrument 7 is adjustably installed on the cross beam frame 6.

[0022] The carrier ring 1 is the main load-bearing structure of the device and provides an installation basis for the structures thereon. The fixed ring 2 provides a fixed working position for the moving ring 3. The moving ring 3 realizes the rotation with the outer shell of the crucible under an external force state through its relative rotational working state with the fixed ring 2. The positioning blocks 4 integrally formed on the inner edge of the moving ring 3 can better fit the bottom of the outer shell of the crucible, increasing the overall stable support. At the same time, through the outer balls 5, the outer shell of the crucible can rotate relatively, further increasing the flexibility of the device. The cross beam frame provides an installation basis for the device, and the fixed measuring instrument 7 measures the relative height difference of the position where it is located through its own functionality.

[0023] Specifically, the fixed measuring instrument 7 includes a fixed cylinder 701 and a locking nut 702. The lower outer circumference of the fixed cylinder 701 is screwed with the locking nut 702. An adjusting screw cylinder 703 is screwed in the fixed cylinder 701. A touch rod 704 is slidably installed in the adjusting screw cylinder 703, and the upper end of the touch rod 704 protrudes from the adjusting screw cylinder 703. A locking ring 706 is fixedly installed at the lower part of the adjusting screw cylinder 703. An extension edge is integrally formed on the outer circumference of the upper part of the touch rod 704. A spring 705 is arranged between the locking ring 706 and the extension edge. A pointer 708 is fixedly installed at the lower end of the adjusting screw cylinder 703. A scale 709 is engraved at the lower end of the touch rod 704, and the pointer 708 and the scale 709 cooperate with each other.

[0024] The fixed cylinder 701 and the locking nut 702 cooperate with each other, enabling the fixed gauge 7 to adjust its position on the crossbeam frame 6. At the same time, the fixed cylinder 701 provides an installation basis for the adjusting screw cylinder 703. Through the threaded fit with the fixed cylinder 701, the adjusting screw cylinder 703 can adjust the overall relative height and provide an installation basis for the internal structure. The contact rod 704, the spring 705 and the locking ring 706 are combined with each other to form an elastic contact structure. The cooperation between the locking ring 706 and the spring 705 enables the contact rod 704 to perform effective reciprocating motion. The cooperation between the pointer 708 and the scale 709 can specifically display the change in height.

[0025] Specifically, the lower end surface of the carrier ring 1 is fixedly installed with circumferentially distributed support legs 8.

[0026] By setting the support legs 8, the applicable environment of the device can be increased, and at the same time, it is convenient for the repair personnel to enter the bottom of the crucible shell for repair and observation.

[0027] Specifically, a lower rail groove is formed on the inner edge of the fixed ring 2, and an upper rail groove is formed on the lower surface of the outer edge of the moving ring 3. The lower rail groove and the upper rail groove cooperate with each other, and internal balls 11 are evenly distributed inside.

[0028] Through the upper rail groove, the lower rail groove and the internal balls 11, the frictional force of the relative rotation between the moving ring 3 and the fixed ring 2 is reduced, facilitating operation.

[0029] Specifically, several circumferentially distributed ear brackets 9 are integrally formed on the outer periphery of the fixed ring 2, and the ear brackets 9 are fixedly combined and installed with the carrier ring 1 through fixing nails 10.

[0030] Through the combination of the ear brackets 9 and the fixing nails 10, the fixed ring 2 and the carrier ring 1 can be stably combined. The fixing nails 10 are rivets or screws.

[0031] Specifically, the inclination angle of the positioning block 4 is 30° - 45°.

[0032] Through the setting of the inclination angle of the positioning block 4, a better support basis for crucible shells of different sizes can be provided.

[0033] Specifically, a limit ring 707 is fixedly installed at the bottom end of the contact rod 704, and the limit ring 707 is located below the locking ring 706.

[0034] Through the limit ring 707, the overall movement of the contact rod 704 is restricted, increasing the working stability of the device.

[0035] Working principle: When in use, place the bottom of the crucible shell inside the moving ring 3, and at the same time make the positioning block 4 contact and fix the bottom of the crucible shell. Before repair, rotate the crucible shell. Under the measurement of the fixed gauge 7, the height difference of the position to be repaired can be effectively detected, so as to facilitate the perception of the repair amount. After repair, rotate again. Under the measurement of the fixed gauge 7, the repair result is detected to facilitate re-inspection.
