[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0024] like Figure 1 - Figure 4 As shown, this application provides a zinc liquid blowing device, including: a blowing box 1, an inlet pipe 2 connected to the top of the blowing box 1, and a blowing connecting frame 3 connected to one end of the blowing box 1, with a blowing pipe 4 connected to the inner side of the blowing connecting frame 3.

[0025] The inner side of the blow pipe 4 is provided with a blow adjustment component, which includes a built-in snap ring 7, and one end of the built-in snap ring 7 is connected to a blow ring 9. A positioning block 5 is provided on the outer side of the built-in snap ring 7, and a movable plate 14 is provided on the outer side of the positioning block 5. The blow adjustment component is used for convenient replacement of the blow ring 9.

[0026] Specifically, such as Figure 2 As shown, a positioning block 5 is connected to one outer end of the blow pipe 4, and a fastening screw 6 is connected to the inner side of the positioning block 5. The fastening screw 6 passes through the positioning block 5 and is connected to the blow pipe connecting frame 3 for positioning the blow pipe 4.

[0027] Specifically, such as Figure 2 As shown, the built-in snap ring 7 is connected to the inside of the blow pipe 4, and the inside of the built-in snap ring 7 is connected to the positioning bracket 8. The built-in snap ring 7 is hidden inside the blow pipe 4. After the blow ring 9 is connected, it is pressed tightly against the end of the blow pipe 4 to improve the stability of the blow ring 9 connection.

[0028] Specifically, such as Figure 2 As shown, a positioning screw 10 is connected to the inner side of the blow ring 9, and the positioning screw 10 is threadedly connected to the positioning bracket 8. The positioning screw 10 is used for internal positioning connection of the blow ring 9.

[0029] Specifically, such as Figure 3 As shown, the positioning block 5 has a positioning groove 11 inside, and the outer side of the spray connecting frame 3 is connected to the rotating connecting frame 12. The inner diameter of the positioning groove 11 is slightly larger than the outer diameter of the positioning pin 15, which facilitates the positioning and fixing of the positioning pin 15.

[0030] Specifically, such as Figure 3 As shown, a reset torsion spring 13 is connected to the inner side of the rotating connecting frame 12, and a movable plate 14 is disposed inside the reset torsion spring 13. A positioning pin 15 is connected to the inner side of the movable plate 14. The reset torsion spring 13 facilitates the movable plate 14 to reset after rotation, so that the positioning pin 15 is inserted into the positioning groove 11 inside the positioning block 5 for fixation.

[0031] The inner side of the blow ring 9 is provided with a blow-disassembly assembly, which includes a blow-through pipe 17 and a blow-through ring 19 is provided on the outer side of the blow-through pipe 17. The blow-disassembly assembly is used for the separation and disassembly of the blow ring.

[0032] Specifically, such as Figure 4 As shown, an internal threaded ring 16 is connected to the inner side of the first spray ring 9, and an external threaded ring 18 is connected to the inner side of the second spray ring 19. The spray pipe 17 is connected to the inner side of the first spray ring 9. The internal threaded ring 16 and the external threaded ring 18 are threadedly connected to each other, and the second spray ring 19 and the first spray ring 9 can be connected to form a spray ring. The spray pipe 17 on the inner side is the air jet channel.

[0033] In this embodiment: the positioning block 5 is connected to the movable plate 14 to pre-position the blow pipe 4 for easy disassembly and assembly. Then, the inner blow ring 1 9 is connected to the blow pipe 4 through the positioning bracket 8, so that the blow ring 1 9 is fixed by a single positioning screw 10, which improves the disassembly and assembly efficiency of the blow ring and facilitates the external cleaning of the blow ring. The blow ring is connected by the internal threaded connection of the blow ring 1 9 and the blow ring 2 19. A blow pipe 17 is also provided on the inner side for connection, so that the blow path is separated, which facilitates internal cleaning and replacement.

[0034] The specific solution is as follows: When zinc spraying is performed on the processed sheet metal inside the spray box 1, zinc liquid is input through the liquid inlet pipe 2, and then the spray pipe 4 blows it to spread the zinc liquid evenly on the surface of the sheet metal. During use, the internal spray ring is prone to being contaminated with dust or residual zinc liquid generated during the spraying process. At this time, the fastening screw 6 can be unscrewed, and the movable plate 14 can be moved to disengage the positioning pin 15 from the positioning groove 11, which facilitates the disengagement of the positioning block 5. Then the spray pipe 4 can be pulled out, and the positioning screw 10 can be unscrewed to remove the spray ring. The spray ring is connected by the internal threads of spray ring one 9 and spray ring two 19. After unscrewing, the inner thread ring 16 and the outer thread ring 18 are separated, and a single severely blocked or damaged spray pipe 17 can be replaced to avoid affecting subsequent spraying.
