Description

Technical Field

[0001] The utility model relates to the technical field of cooling passivation equipment, in particular to a hot-dip galvanizing cooling passivation device. Background Art

[0002] Hot-dip galvanizing is to make the molten metal react with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined. Hot-dip galvanizing can effectively improve the corrosion resistance of the metal and extend the service life of the metal. After the metal is hot-dip galvanized, the surface temperature is very high. The more intense the diffusion reaction is, the thicker the alloy layer will be, which will affect the toughness of the galvanized layer. In order to terminate this heat diffusion as soon as possible, the hot-dip galvanized metal must be forced to cool in time. The cooling method generally adopts air cooling or water cooling. After the hot-dip galvanizing of the disc-type steel scaffolding is completed, the hot-dip galvanized steel scaffolding is generally placed in a cooling water pool for cooling. During the cooling process, a layer of impurities will float on the surface of the cooling water pool, and the floating impurities need to be cleaned up quickly by humans to avoid the impurities being re-adsorbed on the hot-dip galvanized steel scaffolding when the hot-dip galvanized steel scaffolding is taken out after cooling, which affects the quality of the hot-dip galvanized steel scaffolding. However, the efficiency of manual cleaning is slow, the cleaning effect is poor, and some impurities will settle at the bottom of the cooling water pool, which is not convenient for cleaning.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0024] Embodiment 1

[0025] Please refer to Figure 1-6 , in the embodiment of the present invention, a hot-dip galvanizing cooling and passivating device includes a support frame 100.

By lifting the pulling plate 120 upward, it is convenient to remove the rectangular plate 150, the guiding shell 160, and the second filter screen 170, and thus facilitate the cleaning of the rectangular plate 150 and the second filter screen 170.

[0031] Embodiment 2

[0032] On the basis of Embodiment 1, for the purpose of improving the collection efficiency of the floating impurities and foreign objects on the surface of the cooling water by the collection mechanism 200.

[0033] As Figure 5-6 shown, in this embodiment, the adjustment mechanism 300 includes a connection shell 310. A connection notch 311 is formed on one side of the connection shell 310, and the inner side wall of the connection notch 311 is fixedly connected to the outer side wall of the cooling water tank 110. A bidirectional lead screw 330 is rotatably connected to the bottom inside the connection shell 310, and a fixed seat 340 is rotatably connected to the middle position of the bidirectional lead screw 330. One end of the fixed seat 340 is fixedly connected to one inner side wall of the connection shell 310. Moving blocks 331 are screwed on the outer sides of both ends of the bidirectional lead screw 330, and a height adjustment unit 350 is arranged on the top of the moving block 331. One end of the connection shell 310 is fixedly connected to a first motor 320, and the output end of the first motor 320 penetrates through the side wall of the connection shell 310 and is fixedly connected to one end of the bidirectional lead screw 330. The length of the connection shell 310 is greater than the length of the cooling water tank 110, and the height of the connection shell 310 is the same as the height of the cooling water tank 110. The height adjustment unit 350 includes a rectangular frame 351. The bottom of the rectangular frame 351 is fixedly connected to the top of the corresponding moving block 331, and a sliding through hole 3511 is formed at the top of one side of the rectangular frame 351.

The C-shaped rod 355 is slidably connected to the sliding through hole 3511, and one end of the C-shaped rod 355 is fixedly connected to the top of the corresponding collection pipe 240.

[0034] During specific implementation, by starting the second motor 352, the second motor 352 drives the screw rod 353 to rotate, causing the rectangular block 354 and the C-shaped rod 355 to move up and down, thereby facilitating the adjustment of the height of the collection pipe 240. Furthermore, the collection pipe 240 can always be in contact with the surface of the cooling water. By starting the first motor 320, the first motor 320 facilitates the rotation of the bidirectional lead screw 330, causing the moving block 331 and the height adjustment unit 350 to move horizontally.
