When the fluorobenzonitrile and the aqueous salt solution are mixed, the mounting tube 7 around can be heated by the electric heating tube 6. Different heat-conducting materials can be arranged in the mounting tube 7, so that different heat-conducting materials can be replaced according to different working conditions. When the electric heating tube 6 is heated, the motor 2 drives the rotating shaft 4 to rotate, so that the heat can be evenly conducted, and the heat can be transferred faster by stirring the solution, thereby further improving the working efficiency;

The bracket 15 is set in a cross shape. The bracket 15 is fixedly connected to the funnel 19. The lower end of the funnel 19 is fixedly provided with a water dividing plate 16, and the middle part of the upper end of the water dividing plate 16 is rotatably provided with an impeller 17, and the impeller 17 is provided with circular holes 18 around it, and the circular holes 18 are all located between the blades. After the solution enters the box 8 and condenses, the electric telescopic rod 14 below lifts the mounting plate 12, and then the motor 13 is started to drive the mounting plate 12 to drive the stopper 11 to rotate, so that the discharge of the solution can be accelerated, and the larger salt crystals in the solution can also be crushed to avoid the salt crystals being too large and clogging the pipeline. When the solution and salt crystals flow to the water-dividing plate 16, the force of the water flow can be used to rotate the impeller 17. The rotation of the impeller 17 can disperse the solution to the surroundings, and can further crush the salt crystals and flow them to the surroundings, thereby preventing the solution from flowing too fast and causing some smaller salt crystals to wash the filter cartridge 21, thereby improving the filtering and desalination effect of the device; a second funnel 19 is provided below the water-dividing plate 16, and the second funnel 19 is fixedly connected to the second box 8, and a mounting pipe 20 is fixedly provided at the lower end of the middle part of the second funnel 19, and the lower end of the mounting pipe 20 is fixedly connected to the second box 8, and the inner portion of the mounting pipe 20 is fixedly connected to the second box 8.

The dispersed solution falls into the second funnel 19 and enters the filter cartridge 21 for filtration. The filter cartridge 21 blocks the salt crystals inside, and the solution enters the box body 8 and is discharged. When the filter cartridge 21 cannot filter well, the hydraulic rod 26 drives the filter cartridge 21 to descend. As the filter cartridge 21 descends, the sealing plate 25 at the upper end is reset under the action of the spring 24 and seals the second funnel 19, so that it can be replaced without affecting the work above, thereby shortening the time required for maintenance.

[0026] Furthermore, sealing strips are arranged around the hydraulic rod 26, so that the filter cartridge 21 can be tightly pressed against the lower end of the funnel 2 19, and the sealing strips around the filter cartridge 21 can be used to seal the filter cartridge 21.

[0027] Working principle: When using the fluorobenzonitrile filtration and desalination integrated equipment, first, when mixing fluorobenzonitrile and aqueous salt solution, the surrounding mounting tube 7 can be heated by the electric heating tube 6. Different heat-conducting materials can be arranged in the mounting tube 7, so as to replace different heat-conducting materials according to different working conditions. While the electric heating tube 6 is heating, the motor 12 drives the rotating shaft 4 to rotate, so that the heat can be evenly conducted and the heat can be transferred faster by stirring the solution, thereby further improving the working efficiency. Secondly, after the solution enters the box body 2 8 and condenses, the electric telescopic rod 14 below will lift the mounting plate 12, and then the motor 2 13 can be started to drive the mounting plate 12 to drive the stopper 2 11 to rotate, so that the discharge of the solution can be accelerated, and the larger salt crystals in the solution can be crushed to avoid the salt crystals being too large and clogging the pipeline. When the solution and salt crystals flow to the water-dividing plate 16, the force of the water flow can be used to rotate the impeller 17. The rotation of the impeller 17 can disperse the solution to the surroundings, and the salt crystals can be further crushed and flowed to the surroundings, thereby preventing the solution from flowing too fast and washing some smaller salt crystals into the filter cartridge 21, thereby improving the filtering and desalination effect of the device; finally, the dispersed solution falls into the funnel 2 19 and enters the filter cartridge 21 for filtration. The filter cartridge 21 blocks the salt crystals inside, and the solution enters the box 2 8 and is discharged. When the filter cartridge 21 cannot filter well, the hydraulic rod 26 drives the filter cartridge 21 to descend. As the filter cartridge 21 descends, the sealing plate 25 at the upper end is reset under the action of the spring 24 and seals the funnel 2 19, so that it can be replaced without affecting the work above, thereby shortening the time required for maintenance. This is the working principle of the fluorobenzonitrile filtration and desalination integrated equipment.
