Description

Technical Field

[0001] This utility model belongs to the field of cleaning equipment technology, specifically relating to an automatic cleaning device for photovoltaic glass calendering rolls. Background Technology

[0002] In the continuous production process of photovoltaic glass, the calender roll, as a core forming component, plays a crucial role in extruding molten glass at high temperatures into glass strips of predetermined thickness and flatness. However, in production environments with temperatures exceeding 800°C, sulfides contained in the molten glass, impurities in the kiln atmosphere, and precipitates from the overflow outlet continuously deposit on the surface of the calender roll, forming a dense oxide layer. This oxide layer significantly reduces the thermal conductivity of the calender roll (measured heat dissipation performance decreases by ≥40%), leading to localized overheating of the roll body. This, in turn, causes defects such as roll surface damage and thermal deformation, ultimately resulting in quality problems such as reduced light transmittance and uneven thickness of the photovoltaic glass, severely restricting production efficiency.

[0003] Currently, cleaning methods mainly consist of manual cleaning and traditional mechanical cleaning equipment. During manual cleaning, operators need to wear high-temperature protective clothing and clean the upper rolls from the side of the calender or above the annealing kiln. This method is not only labor-intensive but also poses a risk of burns due to the high temperature in the washing area. Furthermore, manual operation is less stable, easily leading to poor cleaning results and production losses from secondary washing. While traditional mechanical cleaning equipment reduces labor intensity to some extent, it still has many problems. For example, some cleaning devices are difficult to assemble and disassemble, requiring multiple people to cooperate under high-temperature conditions; the pressure stability of the cleaning liquid in some devices cannot be guaranteed, resulting in unsatisfactory washing results; and some devices cannot target specific areas of the calender rolls for cleaning, failing to meet the specific requirements of production operations.

[0004] Therefore, there is an urgent need for an automatic cleaning device for photovoltaic glass calendering rolls that can solve the above problems, so as to improve cleaning efficiency and effect, reduce labor intensity and production costs, and ensure the production quality and efficiency of photovoltaic glass.
