[0002] Hot-dip galvanizing, also known as hot-dip zinc plating and hot-dip galvanizing, is to immerse the rust-removed steel parts into the molten zinc at about 500 °C, so that the zinc layer adheres to the surface of the steel components, thereby achieving the purpose of anti-corrosion.

[0003] When the cooling device for hot-dip galvanizing in the prior art cools the galvanized sheet, the galvanized sheet needs to be placed in the feeding tray. Since the contact area between the galvanized sheet and the feeding tray is large, the contact surface between the galvanized part and the cooling device is reduced, thereby reducing the cooling efficiency of the cooling device for cooling the steel components, making the galvanized sheet unable to be cooled evenly, and the hot air generated during the cooling process of the galvanized sheet is wasted, resulting in waste of resources. Therefore, a cooling device for hot-dip galvanizing is needed to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a cooling device for hot-dip galvanizing to solve the problems put forward in the above background art.

[0008] As a preferred implementation manner, the blower is arranged between the flow equalizing plate and the dust-proof net.

[0009] As a preferred embodiment, sliders are connected to both sides of the movable plate, and the two sliders are both slidably connected in the chute, and the two chutes are both opened in the support shell.

[0010] As a preferred embodiment, the shapes of the limiting ring, the first limiting groove and the second limiting groove are all set to be circular.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

Specific implementation mode

[0019] The following further describes the present utility model in conjunction with embodiments.

[0020] The following embodiments are used to illustrate the present utility model, but cannot be used to limit the protection scope of the present utility model. The conditions in the embodiments can be further adjusted according to specific conditions. Any simple improvement of the method of the present utility model under the premise of the concept of the present utility model belongs to the scope protected by the present utility model.

[0021] Please refer to Figures 1-4 , the present utility model provides a cooling device for hot-dip galvanizing, including a support shell 1. The lower surface inside the support shell 1 is connected with a motor 2. The upper surface of the support shell 1 is clamped with an electric push rod 3. The bottom end of the electric push rod 3 is connected with a movable plate 4. Both sides of the movable plate 4 are connected with sliders 18. Both sliders 18 are slidably connected in sliding grooves 17. Both sliding grooves 17 are opened inside the support shell 1. By setting the sliders 18 and the sliding grooves 17, the sliders 18 slidably connected in the sliding grooves 17 can limit the movable plate 4, so that the movable plate 4 is not easily rotated under the action of the electric push rod 3, so that the movable plate 4 can drive the fixed seat 6 to move smoothly along the axial direction of the electric push rod 3 through the rotating rod 5;

[0022] Rotating rods 5 are rotatably connected to both the lower surface of the movable plate 4 and inside the support shell 1. The bottom end of the lower rotating rod 5 is connected with the motor 2. Both ends of the two rotating rods 5 close to each other are connected with the fixed seat 6. By setting the motor 2, the working motor 2 can drive the galvanized sheet 8 inside it to rotate through the rotating rod 5 and the fixed seat 6;

[0023] The cross-sectional shape of the fixed seat 6 is set to be U-shaped. Both sides of the two fixed seats 6 close to each other are respectively lapped with the galvanized sheet 8 through a plurality of ejector rods 7. By setting the ejector rods 7, the ejector rods 7 in the fixed seat 6 reduce the contact area between the fixed seat 6 and the galvanized sheet 8, so that the heat gathered at the top and bottom of the galvanized sheet 8 can also be smoothly blown away by the air flow generated by the blower;

[0024] An air outlet cavity 9 is formed in the support shell 1. A exhaust pipe 10 is connected to the back surface of the support shell 1. The support shell 1 is communicated with the exhaust pipe 10 through the exhaust cavity. A heat preservation pipe 11 is sleeved on a part of the outer surface of the exhaust pipe 10. The front surface of the support shell 1 is hinged to a door panel 12 through a plurality of hinges. A hair dryer 13 is connected inside the door panel 12. A flow equalizing plate 14 and a dust-proof net 15 are clamped inside the door panel 12. By arranging the dust-proof net 15, the dust-proof net 15 can block sundries in the external air, so that external sundries are not easy to enter the support shell 1 and then adhere to the surface of the galvanized sheet 8 to be cooled;

[0025] The hair dryer 13 is arranged between the flow equalizing plate 14 and the dust-proof net 15. By arranging the flow equalizing plate 14, the air flow blown out by the working hair dryer 13 can be evenly blown inside the support shell 1 through the flow equalizing plate 14;

[0026] A first limiting groove 19 and a second limiting groove 20 are respectively formed in the movable plate 4 and the support shell 1. Limiting rings 16 are rotatably connected in both the first limiting groove 19 and the second limiting groove 20. One side of the two limiting rings 16 close to each other is connected to the fixed seat 6. The shapes of the limiting rings 16, the first limiting groove 19 and the second limiting groove 20 are all set to be circular. By arranging the first limiting groove 19, the second limiting groove 20 and the limiting rings 16, since the two limiting rings 16 are respectively slidably connected in the first limiting groove 19 and the second limiting groove 20, the fixed seat 6 connected to the two limiting rings 16 can respectively rotate stably around the first limiting groove 19 and the second limiting groove 20.

[0027] The working principle and usage process of the present utility model: When it is necessary to cool the galvanized sheet 8, the galvanized sheet 8 is placed between the two fixed seats 6, and then the electric push rod 3 is controlled to drive the upper fixed seat 6 to move downward through the movable plate 4 and the upper rotating rod 5, so that both of the two fixed seats 6 fix the galvanized sheet 8 through a plurality of ejector rods 7. Then the exhaust pipe 10 is spirally wound around an external water tank. Since a heat preservation pipe 11 is arranged outside the part of the exhaust pipe 10 between the support shell 1 and the water tank, the hair dryer 13 and the motor 2 are controlled to work. The working motor 2 drives the galvanized sheet 8 to rotate inside the support shell 1 through the lower rotating rod 5 and the lower fixed seat 6. At the same time, the air flow generated by the working hair dryer 13 blows the heat on the surface of the rotating galvanized sheet 8 into the exhaust pipe 10 through the air outlet cavity 9, and then the heat in the exhaust pipe 10 is absorbed by the water in the external water tank, so that the heat in the hot air blown out when the device cools the galvanized sheet 8 is reasonably utilized.

[0028] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
