Description

Technical Field

[0001] The utility model relates to the technical field of graphite boat drying, in particular to a graphite boat chain drying device. Background Art

[0002] In the photovoltaic industry, graphite boats serve as carriers for silicon wafers during production, ensuring smooth and efficient processing in high-temperature environments. The use of graphite boats not only improves the production efficiency of photovoltaic products but also reduces production costs, enabling more precise manufacturing of solar cells and improving overall energy conversion. Furthermore, due to their long lifespan and recyclability, graphite boats are environmentally friendly, further solidifying the photovoltaic industry's leading position in sustainable development. Graphite boats must be cleaned after use to reduce the impact of residual impurities on the product. After cleaning, the boats are then dried in an oven to reduce the impact of residual liquids. Currently, graphite boat drying methods often require the boats to be placed in a basket, which supports the boat and allows for adequate contact between the hot air and the boat's surface.

[0003] Chinese patent CN217748339U discloses a graphite boat cleaning and drying system, comprising a cleaning device and a drying device. The drying device includes a drying channel and a cooling system, and further includes a drying basket return structure disposed on one side of the cleaning device and the drying device; and a first transfer structure disposed between the cleaning device and the drying device. The first transfer structure uses a clamp to clamp the drying basket from the drying basket return structure to the feed end of the drying device, then drives the clamp to clamp the cleaned graphite boat to the drying basket, allowing the graphite boat and drying basket to pass through the drying device for drying. The graphite boat is then cooled by the cooling system, completing the cleaning and drying of the graphite boat. During the cleaning and drying process, the graphite boat and drying basket are transported by the first transfer structure, eliminating the need for manual handling, reducing the labor intensity of the staff and improving the cleaning and drying efficiency of the graphite boat.

[0004] However, it has the following disadvantages: currently, hot air drying uses a double-layer iron frame basket, which makes the transportation of the graphite boat more complicated, and requires an iron basket return turnover structure, which has a complex structure and occupies a large area. Therefore, it is necessary to provide a graphite boat chain drying equipment that makes the transportation and operation of the graphite boat more convenient to solve the above problems.
