Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of quartz crucible processing, in particular to a surface treatment equipment for quartz crucible production. BACKGROUND

[0002] At present, in the solar silicon cell industry, the polycrystalline silicon ingot casting process has very high requirements for equipment, among which the quartz crucible as a special process equipment plays a crucial role. The quartz crucible has the advantages of high purity, high temperature resistance, large size and high precision, good heat preservation, energy saving and stable quality, and is widely used in the process of silicon ingot casting. However, in the actual production process, in order to ensure the surface smoothness of the quartz crucible and the stability of the subsequent use, the surface treatment process is particularly important.

[0003] At present, the surface treatment of the quartz crucible mainly adopts the following steps:

[0004] 1. soaking treatment: using a mixed solution containing fluoride salt, hydrochloric acid and peroxide compound to soak the quartz crucible, so that the surface can effectively remove pollutants and impurities;

[0005] 2. deionized water rinsing: after chemical soaking, the crucible surface is rinsed with deionized water to further remove residual chemical reagents and pollutants;

[0006] 3. drying treatment: the quartz crucible after rinsing needs to be dried by a special drying device to ensure that the surface is free of water marks and provide conditions for the subsequent process.

[0007] However, the existing quartz crucible surface treatment equipment generally has some defects. The traditional equipment usually adopts the way of moving trolley to move the quartz crucible between the soaking kettle, the cleaning kettle and the drying machine. This transmission method is not only cumbersome to operate, but also inevitably collides during the movement of the crucible, which may cause scratches or cracks on the surface of the quartz crucible, seriously affecting the product quality and the service life of the equipment.
