[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0023] The present utility model provides the following technical solutions: As Figure 1 - Figure 5As shown, in this embodiment, a hot-dip galvanizing furnace pot for hot-dip galvanizing of steel structural parts includes a furnace pot body 1, one side of the furnace pot body 1 is fixedly connected to a driving box 2, the middle part of the driving box 2 is rotatably connected to a driving gear 6, the middle part of the driving gear 6 is fixedly connected to a transmission shaft 17, both sides of the outer wall of the driving gear 6 are meshed with driven racks 5, one side of the two driven racks 5 is fixedly connected to a connecting rod 7, one end of the two connecting rods 7 is fixedly connected to a scraper 3, one side of the two scrapers 3 is fixedly connected to an L-shaped support frame 20, and the two L-shaped support frames 20 are Collecting frames 4 are placed on the inner walls, and the zinc water is heated by the furnace body 1. Zinc slag floats on the surface of the zinc water during heating. The driving device 11 is turned on, and the driving gear 6 rotates in the driving box 2, so that the two driven racks 5 slide in the driving box 2, and the two scrapers 3 are close to each other, so that the two scrapers 3 put the zinc slag floating on the surface of the zinc water into the collecting frames 4. When the two collecting frames 4 are fitted together, the staff uses tools to clean up the zinc slag in the two collecting frames 4. This structure is simple and easy to operate, which improves the cleaning efficiency of the zinc slag and also improves the efficiency of hot-dip galvanizing of steel structures.

[0024] like Figure 1 and Figure 2 As shown, a driving device 2 11 is fixedly installed on one side of the driving box 2, and the output end of the driving device 2 11 is transmission-connected with a worm 15, and the outer wall of the worm 15 is meshed with a worm wheel 16, and the middle part of one side of the worm wheel 16 is fixedly connected to one end of a transmission shaft 17. Through the cooperation of the worm wheel 16 and the worm 15, the rotational force of the driving device 2 11 can be decelerated to prevent the transmission shaft 17 from rotating too fast, resulting in the zinc slag on the surface of the zinc water not being cleaned up.

[0025] like Figure 4 As shown, one side of the two driven racks 5 is fixedly connected with a sliding bar 18, and the inner wall of the drive box 2 is provided with two sliding grooves 19, and the inner walls of the two sliding grooves 19 are respectively slidably connected with the outer walls of the two sliding bars 18, and the sliding of the driven rack 5 is restricted by the structural restrictions of the sliding grooves 19 and the sliding bars 18.

[0026] like Figure 1 and Figure 5 As shown, one end of the two scrapers 3 is fixedly connected to a sliding block 23, and the outer walls of the two sliding blocks 23 are slidably connected to the inner wall of the furnace body 1. The sliding blocks 23 slide on the inner wall of the furnace body 1 to support the scrapers 3 and the collecting frame 4 to prevent deformation of the scrapers 3 and the collecting frame 4 due to long-term use.

[0027] like Figure 5As shown in the figure, fixing bolts 21 are connected to the outer side walls of the collection box 4. One end of each fixing bolt 21 is bolted to one side of the L-shaped support frame 20. On both sides of the upper end of the collection box 4, handles 22 are fixedly connected. By using tools to rotate the fixing bolts 21, the fixing bolts 21 are removed from the L-shaped support frame 20 to release the restriction on the collection box 4. Then, the collection box 4 is removed from the scraper 3, and a new collection box 4 is placed on the L-shaped support frame 20 for fixation, thus completing the replacement of the collection box 4. This prevents the zinc slag in the collection box 4 from clogging the filtration holes after long-term use, which affects the filtration of zinc water by the collection box 4.

[0028] As Figure 1 and Figure 3 As shown in the figure, a base 12 is fixedly connected to the lower end of the furnace pot body 1, and a second connecting rod 13 is fixedly connected to the outer side wall of the furnace pot body 1. One side of each of the multiple second connecting rods 13 is fixedly connected to a support rod 14, and one end of each of the multiple support rods 14 is fixedly connected to the inner wall of the base 12. Through the structural design of the second connecting rod 13 and the support rod 14, the strength of the furnace pot body 1 can be enhanced.

[0029] As Figure 1 and Figure 3 As shown in the figure, a first driving device 8 is fixedly installed in the middle of one side of the furnace pot body 1. The output end of the first driving device 8 is drivingly connected to a rotating shaft 9, and multiple stirring rods 10 are fixedly connected to the outer side wall of the rotating shaft 9. Through the structural design of the stirring rods 10, the zinc water in the furnace pot body 1 can be evenly heated.

[0030] The present utility model provides a hot-dip galvanizing furnace pot for steel structural parts, and the specific working principle is as follows:

[0031] When hot-dip galvanizing steel structural parts, first pour zinc water into the furnace pot body 1, and then use the heating device in the furnace pot body 1 to heat the zinc water. After heating is completed, turn on the second driving device 11. The driving gear 6 rotates in the driving box 2, causing the two driven racks 5 to slide in the driving box 2, and the two scrapers 3 approach each other, so that the two scrapers 3 scoop up the zinc slag floating on the surface of the zinc water into the collection box 4. When the two collection boxes 4 are in contact, the staff use tools to clean the zinc slag in the two collection boxes 4, and then put the steel structural parts into the furnace pot body 1 for hot-dip galvanizing. When the filtration holes in the collection box 4 are severely clogged after long-term use, use tools to rotate the fixing bolts 21, remove the fixing bolts 21 from the L-shaped support frame 20 to release the restriction on the collection box 4, then remove the collection box 4 from the scraper 3, place a new collection box 4 on the L-shaped support frame 20 for fixation, thus completing the replacement of the collection box 4, and then repeat the above operation to clean the zinc slag floating on the surface of the zinc water.
