[0025] The conveying crystal fan blade 12 is fixedly connected to the output end of the second motor 7. The conveying crystal fan blade 12 is rotatably connected to the inner wall of the connecting component 5. The connecting assembly 15 includes a housing 151, a baffle 152, and a shaft component 153. A third motor 16 is fixedly connected to the outer wall on the right side of the housing 151. The shaft component 153 is rotatably connected to the inner wall of the housing 151.

Rotary seal rings are usually made of materials such as rubber and polytetrafluoroethylene, and have good sealing performance and wear resistance.

[0026] As Figure 4 shown, when evaporation is carried out, since the lower opening part of the steam outlet 17 coincides with the upper opening part of the evaporation furnace body 11, the first motor 6 is used to drive the gear component 9 to rotate, and then drive the gear ring 10 meshing with the gear end of the gear component 9 to rotate.

[0028] Working principle: When using this device for heating and evaporation, since the connecting assembly 15 is in a closed state, first use the first motor 6 to drive the gear component 9 to rotate. The gear component 9 drives the gear ring 10 to rotate. Then, the evaporation furnace body 11 aligns the opening with the lower end of the steam outlet 17. Subsequently, liquid is injected into the water injection port 8. Then, the liquid enters the connecting component 5. Then, the second motor 7 is started to drive the conveying crystal fan blade 12 to rotate, so as to bring the liquid into the filtering component 14. Then, the heater 18 is used to start heating. Then, the vacuum device 19 is turned on.

[0029] After the heating is completed, the first motor 6 is used to drive the gear component 9 to rotate, thereby driving the evaporation furnace body 11 to rotate. Subsequently, the opening of the evaporation furnace body 11 is aligned with the filter screen below the filter component 14, and then wait for liquid separation.

[0030] After the separation is completed, the connecting component 5 is adjusted to an open state. Subsequently, the conveying crystal fan blade 12 is rotated, so as to bring the solid crystals attached to the surface of the filter component 14 and the crystals inside the filter component 14 into the inside of the connecting assembly 15, and then collected. Thus, it can solve the problem that after the existing evaporator separates crystals after crystallization, crystals are easily adsorbed on the filter component, and the crystals adsorbed on the filter component are difficult to separate. Therefore, when collecting crystals, it is time-consuming and laborious.
