Description

Technical Field

[0001] The utility model relates to the technical field of graphite crucible production, in particular to slag cleaning equipment used for graphite crucible production. Background Art

[0002] Graphite crucible has good thermal conductivity and high temperature resistance. During high temperature use, the thermal expansion coefficient is small, and it has certain strain resistance to rapid heating and cooling. It has strong corrosion resistance to acid and alkaline solutions and excellent chemical stability. In metallurgy, casting, machinery, chemical industry and other industrial sectors, it is widely used in the smelting of alloy tool steel and the smelting of non-ferrous metals and their alloys, and has good technical and economic effects. In the production process of graphite crucible, some waste slag is easy to adhere to its inner wall, which needs to be cleaned and removed.

[0003] Referring to the existing authorized announcement number CN220144255U, "A slag cleaning device for graphite crucible production", it can ensure the smooth and intact inner wall of the crucible through flexible grinding with steel brush bristles; reduce physical labor and save costs; eliminate rigid impact and human body injury. It is not limited by the site and occupies a small space; it is easy to operate, easy to maintain, and has high durability. It solves the problem that the waste slag adhering to the inner wall of the existing graphite crucible is mostly cleaned manually, which is greatly affected by the physical strength of the personnel and the environment, and the crucible cleaning quality and output are restricted.

[0004] However, the solution proposed in the above-mentioned existing patent still has at least the following deficiencies: the steel brush is arranged on the spiral blade and the end brush holder; since the diameter of the spiral rod is relatively fixed, the distance between the steel brush and the axis of the spiral rod cannot be adjusted as needed, so that it is only suitable for slag cleaning operations of crucibles of relatively fixed sizes; if the inner wall of the crucible with a larger inner diameter is to be cleaned, it is necessary to control the crucible to rotate eccentrically around the axis of the spiral rod, which makes it not well suitable for slag cleaning operations on the inner wall of crucibles with different inner diameters. Therefore, the utility model proposes a slag cleaning device for graphite crucible production to solve the above problems.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.
