Technical Field

[0001] The utility model relates to the technical field of solar cell production and drying, in particular to a drying device. Background Art

[0002] With the increasing global demand for renewable energy, the solar photovoltaic industry has developed rapidly, with the trend of low cost, high efficiency and large output. In the production process of solar cells, they need to be cleaned in various process tanks and then dried in drying tanks before being sent to the next process.

[0003] Existing drying tanks usually have air blowing ducts on the side walls of the tank body to dry the film boxes in the tank body. However, due to the increase in production, 6 film boxes can now be stored in the tank body at the same time, which puts higher requirements on drying. The existing drying method concentrates the wind force on the periphery of the film box, and the air volume for the bottom of the film box and the film box located in the middle of the tank body is small, so the drying effect is not ideal, and it is no longer suitable for large-scale drying methods.

[0004] Therefore, how to solve the difference in drying effect between the film boxes is a technical problem that needs to be solved urgently in this field. Utility Model Content

[0005] In order to solve the technical problems mentioned in the background technology, the utility model provides a drying device.

[0007] Furthermore, it also includes: an air inlet cavity, which is arranged on the air inlet side of the air inlet plate; the air inlet cavity is provided with a funnel-shaped air inlet; and an air inlet duct is connected to one side of the lower opening of the air inlet.

[0008] Furthermore, an air guide plate is provided in the air inlet cavity.

[0009] Furthermore, a filter assembly is provided on the air inlet duct.

[0010] Furthermore, a heating component is provided on the air inlet duct.

[0013] Furthermore, air uniforming plates are provided in the air inlet cavity and the air outlet cavity.

[0014] Furthermore, a driving component is provided between the air inlet duct and the air outlet duct for cyclic drying.

[0015] Furthermore, a tank cover is provided above the drying tank to cooperate with the drying tank to form a sealed space.

[0016] The beneficial effect of the utility model is that the drying device of the utility model opens ventilation holes at the bottom of the air inlet plate and closes the bottom of the air outlet plate at the same time, so that the air inlet and outlet plates, the film box support strips, and the bottom of the drying slot jointly form an air cavity with only an upward air duct left, effectively increasing the air outlet at the bottom of the film box and the middle of the slot body, and improving the drying effect of the battery cells.
