[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Photovoltaic panels, also known as solar panels, are devices that convert sunlight energy directly into electrical energy through the photovoltaic effect. Their working principle is based on the photoelectric properties of semiconductor materials. When sunlight shines on photovoltaic panels, photons (energy units of light) interact with electrons in semiconductor materials, allowing electrons to gain enough energy to jump from the valence band to the conduction band, forming free electron-hole pairs. These free electrons move under the action of the electric field to form current, thereby generating electrical energy. As a renewable energy technology, photovoltaic panels have the advantages of being clean, safe, and low in maintenance costs, and have been widely used and developed around the world.

[0029] The recycling of used photovoltaic panels is an important area involving environmental protection and resource recycling. With the rapid development of the global photovoltaic industry, a large number of photovoltaic panels need to be properly recycled after reaching the end of their service life. The recycling of used photovoltaic panels avoids the pollution of the environment caused by a large amount of photovoltaic panel waste, and recycles valuable materials such as silicon, silver, copper, etc., reducing the demand for new resources. In addition, recycling reduces the energy consumption and carbon emissions of new raw materials. In the recycling process of used photovoltaic panels, the used photovoltaic panels need to be placed in a container containing organic solvents for pretreatment. After the treatment is completed, the photovoltaic panels need to be centrifuged and dried by the corresponding centrifugal device to remove excess organic solvents.

[0030] Most of the existing centrifugal devices for recycling waste photovoltaic panels have a single function and only have a single centrifugal function. They cannot promptly clean and dry the waste photovoltaic panels after the organic solvents on them are spun off, and the solid material residues in the organic solvents spun out by centrifugation cannot be filtered out in time, which reduces the recycling efficiency of the waste photovoltaic panels to a certain extent. In addition, the storage and placement mechanism for the waste photovoltaic panels is not easy to adjust, and cannot be applied to the centrifugal recycling of waste photovoltaic panels of different sizes.
