However, in the above patents, the spray thermal decomposition device has poor separation of gas and product particles, and the production efficiency is not high, which reduces the separation efficiency of nanomaterial preparation.

The mixed mist is forced to rotate by the spiral air guide plate. The centrifugal force of the rotation causes the particles to enter the spiral groove, strengthen the separation, and perform pyrolysis with hot air. The nanoparticles in the liquid are separated and fall into the second storage box, thereby avoiding material waste due to uneven separation of nanomaterials and improving the working efficiency of the separation device for nanomaterial preparation.

[0026] like Figure 4 As shown, a storage tray 6 is rotatably provided at one end of the bottom of the first storage box 2 and one end of the bottom of the second storage box 3 , and a partition plate 20 is fixedly provided at the middle position of the two storage trays 6 .

[0027] like Figure 1 As shown, a base plate 4 is fixedly provided at the bottom end of the positioning frame 1, and motors 21 are fixedly provided at both ends of the middle position of the top of the base plate 4, and the output ends of the two motors 21 pass through the positioning frame 1 and are fixedly connected to the middle positions of the bottoms of the two storage trays 6 respectively, and a switch panel is fixedly provided on one side of the positioning frame 1, and a motor switch, an air pump switch, a first liquid feed pump switch and a second liquid feed pump switch are fixedly provided on the surface of the switch panel respectively, and the two motors 21, the air pump 8, the first liquid feed pump 14 and the second liquid feed pump 16 are electrically connected to the external power supply through the motor switch, the air pump switch, the first liquid feed pump switch and the second liquid feed pump switch respectively.

[0028] The working principle of the present invention is as follows: Figure 1 - Figure 3 and Figure 5As shown, the hot air sprayed by the hot air source 7 and the liquid material mist containing nanoparticles form a mixed aerosol, and the spiral air guide plate 22 forces the mixed aerosol to rotate. The centrifugal force of the rotation causes the particles to enter the spiral groove 19, and the separation is enhanced.

The centrifugal force of the rotation causes the particles to enter the spiral groove 19, strengthen the separation, and perform pyrolysis with hot air, so that the nanoparticles in the liquid are separated and fall into the second storage box 3. The remaining waste gas is transported and processed through the second waste gas pipe 18, thereby avoiding the waste of materials due to the uneven separation of nanomaterials and improving the working efficiency of the separation device for preparing nanomaterials.

[0029] like Figure 4 As shown, turn on the motor switch so that the output end of the motor 21 fixed on the top of the bottom plate 4 drives the storage tray 6 to rotate. The storage tray 6 is separated by the middle partition plate 20, so that the two ends of the partition plate 20 can be indirectly unloaded, so that while the nanomaterials are continuously falling downward, the materials can be indirectly collected, avoiding the problem of accumulation of the storage of nanomaterials and improving the unloading efficiency of nanomaterials.
