Description

Technical Field

[0001] The invention relates to the technical field of crucible repair, in particular to graphite crucible repair equipment. Background Art

[0002] Graphite crucibles are mainly made of graphite as the main raw material. They are processed through a specific process and have a specific shape and structure. They are used to contain and process various substances in a high-temperature environment. The production process is generally to start the rotary canning machine, make it reach the set speed, and then start to evenly add material into the mold. When the set molding time is reached, the crucible is fully solidified, and the rotary canning machine is stopped before demoulding.

[0003] Graphite crucible deformation can occur during the prior art graphite crucible molding process due to factors such as unstable rotational speed and mold wear. Unstable rotational speed during operation of the rotational molding equipment results in uneven centrifugal force on the material. This uneven material distribution leads to inconsistent thickness across the crucible. Furthermore, after long-term use, the mold surface wears, reducing the mold's dimensional accuracy. This can result in the finished crucible not meeting design requirements, resulting in an irregular shape and prone to deformation.

[0004] In the prior art, when repairing a deformed graphite crucible, a cutting device is generally used to manually cut off the excess portion of the graphite crucible and then grind it, and the thin and less material is manually added to achieve the repair of the graphite crucible. However, when the cutting device is manually operated, it is impossible to accurately locate the cutting position, which may result in excessive cutting of the graphite crucible. In addition, the repairing operation requires the inner and outer end surfaces of the graphite crucible to be repaired in sequence, resulting in low efficiency of the graphite crucible repairing.

[0053] Combined with attachment Figure 3 , Attachment Figure 4 , Attachment Figure 5As shown:

[0054] The graphite paste extrusion structure 81 includes a delivery pipe 811 located at the top of the equipment box 1 and capable of conveying graphite paste. An extrusion pipe 812 passing through the equipment box 1 is inserted into the delivery pipe 811.

A circular groove 512 is provided on the turntable 511, and a plurality of through grooves 513 are provided on the circular groove 512. The output end of the end pipe 813 is located directly above the through groove 513.

[0055] During grinding, the driving motor 311 needs to work at a high speed. After grinding, the driving motor 311 is rotated slowly at a low speed. In the present invention, the graphite paste needs to be extruded, that is, the graphite paste is loaded into the paste cylinder of the press and extruded. The press is a prior art and is not described in detail in the present invention. The driving motor 311 rotates slowly at a low speed while the graphite paste is transported from the conveying pipe 811 to the end pipe 813 through the extrusion pipe 812 and outputted from the end pipe 813 to the gap between the inner grinding mechanism 51 and the outer grinding mechanism 61. Since the relative position of the end pipe 813 and the crucible body 2 is fixed at this time, the graphite paste needs to be discharged slowly, and the rotating turntable 511 during the process will move the excess graphite paste on the annular groove 512 to the unfilled position. At this time, the crucible body 2 is repaired.

[0056] After the blanking is completed, a small amount of graphite paste will be attached to the inner grinding part 515 and the outer grinding part 612 on the inner grinding mechanism 51 and the outer grinding mechanism 61. When the attached graphite paste affects the subsequent grinding work, the staff is required to mechanically clean the inner grinding part 515 and the outer grinding part 612, for example, using a brush. The connection method between the mounting seat 1 514 and the mounting seat 2 611 and the inner grinding part 515 and the outer grinding part 612 of the present invention is that locking bolts are provided on the mounting seat 1 514 and the mounting seat 2 611 to abut against the inner grinding part 515 and the outer grinding part 612. When cleaning, the inner grinding part 515 and the outer grinding part 612 can be disassembled by loosening the locking bolts.

[0057] The present invention provides a graphite crucible blanking device. When using the present invention to repair a graphite crucible:

[0058] The crucible body 2 is fixed in the equipment box 1 through the clamping structure 21, and the grinding drive mechanism 31 is started to simultaneously drive the inner grinding mechanism 51 and the outer grinding mechanism 61 to rotate through the upper transmission structure 41 and the lower transmission structure 42. During the rotation of the inner grinding mechanism 51 and the outer grinding mechanism 61, the manually operated adjustment mechanism 71 drives the inner grinding mechanism 51 and the outer grinding mechanism 61 to move in opposite directions. During the process, the inner grinding mechanism 51 and the outer grinding mechanism 61 can grind the inner and outer end surfaces of the crucible body 2. During the grinding process, the dust removal device 91 can extract dust particles. Afterwards, the graphite paste extrusion structure 81 extrudes the graphite paste to repair the missing part of the crucible body 2 to complete the repair work of the crucible body 2.

[0059] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above and, without departing from the purpose of the present invention, designs structures and embodiments similar to the technical solution without creatively designing, they shall fall within the scope of protection of the present invention.
