Description

Technical Field

[0001] The utility model relates to the technical field of galvanized pipe production equipment, in particular to a water vapor recovery device for a hot-dip galvanizing cooling water tank used for galvanized pipes. Background Art

[0002] Due to process requirements, hot-dip galvanized steel pipes in galvanizing production lines still require cold water cooling before entering the next process. In open circulating water pool cooling systems, cooling water loss primarily occurs in the form of unorganized vapor from above the pool. Furthermore, chromic anhydride is added to the pool, and some of the evaporated water naturally drifts into the air, condensing and falling on equipment or rising up to the roof panels, accelerating equipment corrosion. This reduces visibility within the workshop, particularly in winter, posing a safety hazard and wasting water resources. Utility Model Content

[0017] like Figure 1-3 As shown, a water vapor recovery device for a hot-dip galvanizing cooling water tank for galvanized pipes includes vertical plates 1 arranged on both sides outside the cooling tank mouth, the top of the vertical plate 1 is connected to a horizontal plate 2, the end of the horizontal plate 2 away from the vertical plate 1 is hinged to a baffle 3, and an adjustment component for controlling the angle of the baffle 3 is installed on the horizontal plate 2.

[0018] The adjustment assembly includes a cylinder 10 installed on the transverse plate 2, a push rod 11 is hinged on the piston end of the cylinder 10, the other end of the push rod 11 is hinged on a connecting block 12, and the connecting block 12 is slidably connected to the shielding plate 3.

[0019] A slider 13 is fixed to the bottom of the connecting block 12 , and the slider 13 is slidably connected to a sliding groove 14 provided on the upper surface of the shielding plate 3 .

[0020] The vertical plate 1 is provided with several mounting holes, into which L-shaped air intake pipes 4 are inserted. One end of the air intake pipe 4 is placed vertically downward within the cooling pool, and the end of the air intake pipe 4 placed within the cooling pool has a beveled port. The other end of each air intake pipe 4 is connected to an air collecting box 5, which is connected to an exhaust fan 7 via a connecting pipe 6. The air outlet of the exhaust fan 7 is connected to a wavy guide pipe 8. The other end of the guide pipe 8 passes through the vertical plate 1 and is placed within the cooling pool. A fan 9 is provided on one side of the guide pipe 8.
