Accelerated seawater salt making device based on photo-thermal material and use method

The invention discloses an accelerated seawater salt making device based on a photo-thermal material and a use method. The device comprises a salt pond and a light absorbing material, wherein sweateris injected in the salt pond, cuboid buoyancy frames float on seawater, and fixing holes are formed in the buoyancy frames; first mounting holes are formed in the left side of the light absorbing material, first connecting devices penetrate the first mounting holes to be mounted in the fixing holes, second mounting holes are formed in the right side of the light absorbing material, second connecting devices penetrate the second mounting holes to be mounted in the fixing holes, and the second connecting devices and the first connecting devices are nails. According to the accelerated seawater salt making device based on the photo-thermal material, the light absorbing material floats on the seawater surface by use of the buoyancy frames, the surface of the light absorbing material is prevented from being wetted by se
