[0023] Specifically, the exhaust filter assembly 6 includes a filter box 61, a dustproof net 62, a moisture-proof layer 63, an activated carbon adsorption layer 64, a fine filter layer 65, a coarse filter layer 66, and a collection chamber 67. The collection chamber 67 is provided on one side of the filter box 61, and the dustproof net 62 is provided on the other side of the filter box 61. The moisture-proof layer 63 is provided inside the filter box 61 near the dustproof net 62, and the activated carbon adsorption layer 64 is provided on the side of the moisture-proof layer 63. The coarse filter layer 66 is provided inside the filter box 61 near the collection chamber 67, and the fine filter layer 65 is provided on the side of the coarse filter layer 66.

[0024] By adopting the above technical solution, the waste such as zinc powder generated is collected in the collection chamber 67, coarsely filtered through the coarse filter layer 66, finely filtered through the fine filter layer 65, finely filtered through the activated carbon adsorption layer 64, and moisture-proof layer 63 absorbs moisture. Then the gas is discharged through the dustproof net 62 to ensure the filtration quality. The moisture-proof layer 63, activated carbon adsorption layer 64, fine filter layer 65 and coarse filter layer 66 can be pulled out and quickly cleaned and replaced to avoid clogging and affecting the filtration efficiency.

[0025] Specifically, sealing gaskets are provided at the joints between the inner wall of the filter box 61 and the moisture-proof layer 63, the activated carbon adsorption layer 64, the fine filter layer 65, and the coarse filter layer 66.

[0026] By adopting the above technical solution, the sealing of the connection is ensured, and gas leakage is avoided.

[0027] Specifically, the collection chamber 67 includes a first inclined plate 671, a second inclined plate 672, and a sealing plate 673. The first inclined plate 671 is provided inside the collection chamber 67 on the side near the coarse filter layer 66, the second inclined plate 672 is provided on the other side inside the collection chamber 67, and the sealing plate 673 is provided on the side of the collection chamber 67.

The steam output from the steam generator 9 is transported to the diversion pipe 12 through the connecting pipe 8. After being diverted by the diversion pipe 12, the steam flows from the diversion pipe 12 to the second end of the steel pipe. Multiple nozzles 15 spray evenly, and the reciprocating motion of the nozzles 15 and the rotation of the steel pipe itself make the steel pipe more evenly sprayed, resulting in a better spraying effect. During the spraying process, steam escapes from the exhaust port 13 and is collected by the collection chamber 67 to collect the generated zinc powder and other waste. The waste is intercepted by inclined plates 671 and 672 to prevent backflow. The waste can be cleaned by opening the sealing plate 673. The gas is coarsely filtered through the coarse filter layer 66, finely filtered through the fine filter layer 65, and the activated carbon adsorption layer 64 adsorbs and filters fine particles. The moisture-proof layer 63 absorbs moisture. Then the gas is discharged from the dustproof net 62 to ensure the filtration quality. The moisture-proof layer 63, activated carbon adsorption layer 64, fine filter layer 65 and coarse filter layer 66 can be pulled out for quick cleaning and replacement to avoid clogging that affects the filtration efficiency and to prevent workers from inhaling the gas and affecting their health.

The limiting seat 174 is provided on the side of the housing 1, the moving rod 172 is slidably connected to the middle of the limiting seat 174, the limiting plate 173 is provided at the end of the moving rod 172 away from the second abutment 16, and the fastening bolt 171 is provided at the upper end of the limiting seat 174.

[0032] By adopting the above technical solution, the fastening bolt 171 is loosened, the limiting plate 173 is pushed to make the moving rod 172 move in the limiting seat 174, the second abutment plate 16 on the side of the limiting seat 174 moves, and the second abutment plate 16 abuts against the side of the steel pipe. The fastening bolt 171 is tightened to fix the position of the moving rod 172. The adjustment is convenient, time-saving and labor-saving.

[0033] Specifically, the fastening bolt 171 is threadedly engaged with the limiting seat 174, the lower end of the fastening bolt 171 contacts the surface of the moving rod 172, and the moving rod 172 is slidably connected with the limiting seat 174.

[0034] By adopting the above technical solution, the moving rod 172 moves in the limiting seat 174, the second abutment 16 on the side of the limiting seat 174 moves, so that the second abutment 16 abuts against the side of the steel pipe, and the fastening bolt 171 is tightened to fix the position of the moving rod 172.

[0035] In this embodiment, when using the device, loosen the fastening bolt 171, push the limiting plate 173 to move the moving rod 172 in the limiting seat 174, move the second abutment plate 16 on the side of the limiting seat 174, so that the second abutment plate 16 abuts against the side of the steel pipe, tighten the fastening bolt 171 to fix the position of the moving rod 172, which is convenient to adjust and saves time and effort.

[0036] The structure and operating principle of the housing 1, driven wheel 2, belt 3, driving wheel 4, motor 5, steam generator 9, reciprocating screw 10, screw sleeve 11, diverter pipe 12, first abutment plate 14, nozzle 15 and second abutment plate 16 in this utility model have been disclosed in a spraying device for a hot-dip galvanized steel pipe production line disclosed in Chinese patent application number 202121870744.0.

[0037] The working principle and usage process of this utility model are as follows: When using this utility model, open the box door 7, place the left end of the steel pipe against the right side of the first abutment plate 14, and the locking block set on the side of the first abutment plate 14 and the second abutment plate 16 that are close to each other abuts the inner ring of the steel pipe, which plays a limiting role in the steel pipe. Loosen the fastening bolt 171, push the limiting plate 173 to move the moving rod 172 in the limiting seat 174, and the second abutment plate 16 on the side of the limiting seat 174 moves, so that the second abutment plate 16 abuts the side of the steel pipe. Tighten the fastening bolt 171. 71. Fix the position of the moving rod 172, and make the second abutment plate 16 abut against the right end of the steel pipe to complete the fixation of the steel pipe. Then close the box door 7. The rotating shaft of the motor 5 drives the first abutment plate 14 and the drive wheel 4 to rotate. The rotation of the first abutment plate 14 drives the steel pipe to rotate, so that the subsequent spraying is more comprehensive and thorough. The rotation of the drive wheel 4, driven by the belt 3, drives the driven wheel 2 to rotate. The reciprocating screw 10 rotates, which in turn drives the two screw sleeves 11 to move back and forth simultaneously, thereby driving the diverter pipe 12 and the nozzle. The steam generator 9, reciprocating approximately 15 times, outputs steam via connecting pipe 8 to distribution pipe 12. After being distributed by distribution pipe 12, the steam is evenly sprayed from multiple nozzles 15. Simultaneously, the reciprocating motion of the nozzles 15 and the rotation of the steel pipe itself ensure more even spraying and a better spraying effect. During the spraying process, steam escapes from exhaust port 13 and is collected in collection chamber 67 to collect zinc powder and other waste materials. These waste materials are then intercepted by inclined plates 671 and 672 to prevent contamination. Backflow prevention: Opening the sealing plate 673 allows for waste removal. The waste undergoes coarse filtration through the coarse filter layer 66, fine filtration through the fine filter layer 65, and fine particle adsorption filtration through the activated carbon adsorption layer 64. The moisture-proof layer 63 absorbs moisture, and then the gas is discharged through the dustproof net 62, ensuring filtration quality. The moisture-proof layer 63, activated carbon adsorption layer 64, fine filter layer 65, and coarse filter layer 66 can be pulled out for quick cleaning and replacement, preventing clogging that could affect filtration efficiency and avoiding inhalation that could harm the health of workers.
