Since the mesh cylinder 18 is mesh-shaped and the desiccant layer 19 is molecular sieve desiccant particles, the rotating molecular sieve desiccant particles will fully contact the spray-like droplets sprayed by the atomizing nozzle 15, thereby realizing the rapid removal of water in the chemical liquid. Subsequently, the dried liquid is collected to the bottom of the inner cavity of the drying box 1 through the upper filter plate 10 and the lower filter plate 11 in turn, replacing the traditional method of using heating and anhydrous solvent replacement, and will not volatilize the effective ingredients in the chemical liquid, thereby reducing the drying cost and improving the drying effect of the chemical liquid.

[0020] The cylinder 16 is provided with a plurality of groups of interconnected through holes 20, the outer walls of both sides of the net cylinder 18 are provided with clamping rods 17, and the bottom of the clamping rods 17 is clamped with the inner wall of the cylinder 16, the desiccant layer 19 is molecular sieve desiccant particles, and the size of the molecular sieve desiccant particles is larger than the size of the holes on the net cylinder 18; the clamping rods 17 and the net cylinder 18 are fixedly connected, and the clamped clamping rods 17 can be conveniently disassembled and assembled, which facilitates the disassembly and assembly of the net cylinder 18.

[0021] The disassembly and assembly structure includes cavities 25 opened on both sides of the inner cavity of the sealing cover 21, and each group of cavities 25 is slidably connected with a sliding seat 26, and a return spring 27 is installed between the inner side of the sliding seat 26 and the inner wall of the cavity 25. The outer side of the sliding seat 26 is connected with a clamping block 28, and the two side walls of the front end opening of the cylinder 16 are provided with clamping grooves 29 adapted to the clamping blocks 28. The front end surface of the sealing cover 21 is provided with slots 22 at both ends, and the slots 22 are connected with the cavities 25, and a moving rod 23 is slidably connected in the slots 22, and the bottom of the moving rod 23 is connected with the top of the sliding seat 26; The moving rod 23 is fixedly connected to the sliding seat 26, and the two ends of the return spring 27 are fixedly connected to the inner side of the sliding seat 26 and the inner wall of the cavity 25 respectively. When installing the sealing cover 21, first, the two groups of moving rods 23 move in the slot 22 in relative directions. At this time, the sliding seat 26 moves inward, the return spring 27 is compressed, and the clamping block 28 is received in the cavity 25 after being stressed. At this time, the size of the sealing cover 21 is just adapted to the opening size of the front end face of the cylinder 16. The sealing cover 21 is installed in the opening.

[0023] Embodiment 2: Reference Figure 6 This embodiment is different from the first embodiment in that: pull rings 24 are installed on the tops of the two groups of moving rods 23, and the hand-held ends of the pull rings 24 are covered with anti-skid rubber sleeves, the outer surface of the clamping block 28 is provided with a damping pad, and the inner wall of the clamping groove 29 is embedded with a corrugated protrusion; the pull ring 24 facilitates the pulling of the moving rod 23, and the anti-skid rubber sleeve plays an anti-skid role to prevent the hand from slipping when holding the pull ring 24, and the damping pad and the protrusion further increase the friction between the two, and further improve the stability of the connection between the sealing cover 21 and the cylinder 16.

[0024] Working principle: Before using the present invention, first, the electrical ends of the electrical equipment on the drying box 1 are electrically connected to the external power supply and the electrical ends of the PLC controller 2, and the liquid filling pipe on the chemical liquid tank 5 (not marked in the figure) is opened to add the chemical liquid into the chemical liquid tank 5, and then the two sets of sealing doors 3 are closed to operate the suction pump 6 and the servo motor 801 through the PLC controller 2. After the suction pump 6 operates, the chemical liquid is transported to the conveying plate 14 and multiple groups of atomizing nozzles 15 through the infusion tube 13. The atomizing nozzle 15 atomizes the liquid to form spray-like droplets. The operation of the servo motor 801 drives the driving gear 802 at the bottom of the rotating shaft to rotate. Since the driving gear 802 and the driven gear The gear 803 is meshed and connected, thereby driving the rotating connecting rod 804 on the inner side of the driven gear 803 to rotate, so that the cylinder 16 rotates, and the spray-like droplets sprayed by the multiple groups of atomizing nozzles 15 will enter the inside of the cylinder 16 through the through holes 20 on the cylinder 16. Since the mesh cylinder 18 is mesh-shaped and the desiccant layer 19 is molecular sieve desiccant particles, the rotating molecular sieve desiccant particles will fully contact with the spray-like droplets sprayed by the atomizing nozzle 15, thereby realizing the rapid removal of moisture in the chemical liquid, replacing the traditional method of using heating and anhydrous solvent replacement, and will not volatilize the effective ingredients in the chemical liquid, thereby reducing the drying cost and improving the drying effect of the chemical liquid; then, the dried liquid The liquid is collected to the bottom of the inner cavity of the drying box 1 through the upper filter plate 10 and the lower filter plate 11 in turn. The amount of the liquid can be detected in real time through the liquid level sensor 9. When the amount of the liquid reaches the previously set value, the liquid level sensor 9 sends a signal to the PLC controller 2. The PLC controller 2 controls the reflux pump 7 to work. The chemical liquid after dehydration can be recovered to the chemical liquid tank 5 through the reflux pipe 12, which is convenient for subsequent use. When installing the sealing cover 21, first, the two groups of moving rods 23 move in relative directions in the slot 22. At this time, the sliding seat 26 moves inward, the reset spring 27 is compressed, and the clamping block 28 is stored in the cavity 25 after being stressed. At this time, the size of the sealing cover 21 is just right. The opening size of the front end surface of the cylinder 16 is adapted, and the sealing cover 21 is installed in the opening. At this time, the clamping grooves 29 on the inner walls on both sides of the opening are aligned with the clamping blocks 28, and then the two groups of moving rods 23 are loosened, and the compressed return springs 27 can automatically return to their positions, that is, the two groups of sliding seats 26 are driven to move in opposite directions, and the clamping blocks 28 on the outer sides of the sliding seats 26 are connected to the corresponding clamping grooves 29, that is, the locking and fixing of the position of the sealing cover 21 is completed.
