Description

Technical Field

[0001] The utility model relates to the technical field of crucible surface treatment, in particular to a ceramic crucible surface treatment device. Background Art

[0002] Ceramic crucible is a kind of ceramic crucible, including silicon carbide graphite crucible. Silicon carbide graphite crucible is a ceramic deep-bottomed bowl-shaped container with the characteristics of high volume density, high temperature resistance, fast heat transfer, acid and alkali corrosion resistance, high high temperature strength, and high oxidation resistance. The surface of ceramic crucible needs to be sandblasted during production.

[0003] After searching, it was found that the publication number is CN219380392U, and the name is a surface treatment device for silicon carbide crucible. The application proposes that in the prior art, when sandblasting the crucible surface, a separate clamping device is often used to fix the crucible to ensure the stability of the crucible during the sandblasting operation. However, from a practical point of view, the clamps in the prior art are mostly clamped directly from the outer surface of the crucible through two clamping plates, and then the clamping plates are in contact with the outer surface of the crucible, which easily blocks more spraying surfaces, resulting in uneven spraying on the actual crucible outer surface and reduced spraying effect. By setting an internal fastening mechanism, the crucible inner surface can be fixed with a clamping device. The fixing effect is implemented in the part, and under the premise of ensuring the stability of the crucible during sandblasting operation, it replaces the disadvantage of the clamping equipment in the traditional technology that clamps from the outer surface of the crucible and blocks the outer surface of the crucible, thereby ensuring the uniformity of the crucible during sandblasting operation and enhancing practicality. However, although this application facilitates the processing of the outer wall by clamping the inner wall of the crucible, when processing the inner surface of the crucible, this application is difficult to clamp the outer surface efficiently and stably, and there are great limitations in its use. At the same time, the top mouth of the crucible is in an inverted state, and the top mouth cannot be surface treated. The working efficiency is not high, and the structure is relatively complex, and further improvements can be made.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

When the outer surface of the ceramic crucible is processed, the ceramic crucible can be turned upside down on the top surface of the external silicone ring 2, and the top opening of the ceramic crucible is inserted into the groove 3. Subsequently, the exhaust pump 11 is started to extract the air inside the hollow platform 1, and the air can be discharged through the exhaust hole 1. 0 extracts the air inside the ceramic crucible, forms a negative pressure inside the ceramic crucible, and makes the top of the ceramic crucible close to the inner bottom surface of the groove 3, thereby fixing the ceramic crucible. When the outer surface of the ceramic crucible is processed, the bottom surface of the ceramic crucible can be placed on the top surface of the internal silicone pad 4, and the vacuum pump 11 is started. The vacuum pump 11 extracts the air inside the sinking groove 5, and the ceramic crucible and the top surface of the internal silicone pad 4 can also be fixed by negative pressure to avoid shaking during sandblasting and spraying. The device can quickly fix the ceramic crucible by starting the vacuum pump 11. The structure is very simple and the working efficiency is high. It is greatly convenient for the staff to process the inner and outer surfaces of the ceramic crucible. At the same time, when the outer surface of the ceramic crucible is fixed, only the top of the ceramic crucible is blocked, and the bottom and outer surfaces of the ceramic crucible can be evenly processed. When the inner surface of the ceramic crucible is processed, the top is processed synchronously at this time, so that the ceramic crucible can be processed in all directions, and there is no processing dead angle, thereby further improving the processing efficiency.

[0030] In one embodiment, the top surfaces of the outer silicone ring 2 and the inner silicone pad 4 are in the same plane, and the outer silicone ring 2 and the inner silicone pad 4 are coaxially arranged with the hollow table 1, wherein the groove 3 is an annular groove, and the groove 3 is coaxially arranged with the outer silicone ring 2, so as to facilitate the central placement of the ceramic crucible and improve the stability of the placement.

[0031] In one embodiment, a plurality of exhaust holes 10 are evenly arranged, and the distribution area of ​​the exhaust holes 10 is smaller than the bottom area of ​​the ceramic crucible, so as to ensure that the bottom surface of the ceramic crucible can completely cover the exhaust holes 10 to avoid air leakage.

[0035] Working principle:

[0036] When the outer surface of the ceramic crucible is processed, the ceramic crucible can be turned upside down on the top surface of the external silicone ring 2, and the top of the ceramic crucible can be inserted into the groove 3. Subsequently, the vacuum pump 11 is started to extract the air inside the hollow platform 1, and the air inside the ceramic crucible can be extracted through the vacuum hole 10, so that a negative pressure is formed inside the ceramic crucible, and the top of the ceramic crucible is pressed against the inner bottom surface of the groove 3, thereby fixing the ceramic crucible. When the outer surface of the ceramic crucible is processed, the bottom surface of the ceramic crucible can be placed on the top surface of the internal silicone pad 4, and the vacuum pump 11 is also started. The vacuum pump 11 extracts the air inside the sinking groove 5, and the ceramic can also be made to be filled with negative pressure. The crucible is fixed to the top surface of the internal silicone pad 4 to avoid shaking during sandblasting and spraying. The device can quickly fix the ceramic crucible by starting the vacuum pump 11. It has a very simple structure and high working efficiency, which greatly facilitates the staff to process the inner and outer surfaces of the ceramic crucible. At the same time, when the outer surface of the ceramic crucible is fixed, only the top mouth of the ceramic crucible is blocked, and the bottom and outer surfaces of the ceramic crucible can be evenly processed. When the inner surface of the ceramic crucible is processed, the top mouth is also processed synchronously, so the ceramic crucible can be processed in all directions without any processing dead angle, thereby further improving the processing efficiency.
