Compared with the traditional cooling device, the device can cool a single galvanized wire, remove a large amount of heat in the wire in advance, and prevent the cooling liquid from being overheated and affecting the cooling quality when the wire enters the cooling tank. The position and number of the nozzles can be adjusted according to the number and spacing of the galvanized wires, so that the nozzles can cool the wires more conveniently and stably, thereby improving the working quality of the device. The device is also suitable for the field of galvanized wire processing.

[0004] In the use process of the above-mentioned cooling device, the position and angle of the spraying structure need to be adjusted to correspond to the position of the galvanized wire, which is laborious and increases the work burden.

[0031] Please refer to Figure 1 , Figure 2 and Figure 3 , the cooling device for hot galvanized wire production in the embodiment comprises a cooling box 1, equidistantly arranged deflection rollers 2 are rotationally connected inside the cooling box 1, water cooling pipes 3 are slidingly inserted inside each deflection roller 2, a top cover 4 is slidingly connected to the top end of the cooling box 1, equidistantly arranged spray pipes 5 are fixedly inserted inside the top cover 4, equidistantly arranged spray heads 6 are arranged at the bottom of each spray pipe 5, a first water inlet pipe 7 is arranged on one side of the top cover 4, one end of each spray pipe 5 is fixedly connected to the outer circumferential surface of the first water inlet pipe 7, and one end of the first water inlet pipe 7 is fixedly connected with a second water inlet pipe 8.

[0032] Please refer to Figure 1 and Figure 3 , the first water inlet pipe 7 is a hard metal pipe, and the second water inlet pipe 8 is a soft plastic pipe. The hard first water inlet pipe 7 has higher stability, and the soft second water inlet pipe 8 has higher flexibility, which can meet the needs of moving opening and closing of the top cover 4.

[0033] Please refer to Figure 2 and Figure 3 , the spray head 6 is a conical frustum structure with narrow top and wide bottom, which promotes the cooling water to be diffusedly sprayed, and improves the uniformity and comprehensiveness of the cooling of the galvanized wire.

[0034] Please refer to Figure 1 , Figure 2 and Figure 4 , the water cooling pipe 3 is a hard metal pipe, and the water cooling pipe 3 and the deflection roller 2 are both made of high thermal conductivity material. The cooling water is circulated inside the water cooling pipe 3, which promotes the heat of the galvanized wire to be transferred to the cooling water through the deflection roller 2 and the water cooling pipe 3, and then to the outside by the cooling water, further optimizing the cooling effect of the galvanized wire.

[0035] Please refer to Figure 2 andFigure 4 The outer circumferential surface of the steering roller 2 is provided with equally spaced partition grooves 9. The partition grooves 9 can separate the galvanized wires and prevent the galvanized wires from contacting each other during the movement process, thus affecting the quality of the galvanized wires.

[0036] Please see Figure 1 and Figure 4 A first positioning ring 10 is fixedly sleeved on one end of the outer circumference of the steering roller 2, and a second positioning ring 11 is threadedly connected to the other end of the outer circumference of the steering roller 2. The first positioning ring 10 and the second positioning ring 11 limit the steering roller 2 to prevent the steering roller 2 from sliding and deviating, thereby improving the stability of the steering roller 2's movement.

[0037] Please see Figure 1 , Figure 2 and Figure 3 The cooling box 1 is fixedly connected to both sides of the support 12. The top of the support 12 is provided with two T-shaped sliding grooves 13. The bottom surface of the top cover 4 is fixedly connected to two T-shaped sliding plates 14. The T-shaped sliding plates 14 are slidably connected to the support 12 through the T-shaped sliding grooves 13. The top cover 4 is restricted by the T-shaped sliding grooves 13 and the T-shaped sliding plates 14 to prevent the top cover 4 from falling off easily and to enable the top cover 4 to slide open and close, thereby facilitating the installation and laying of galvanized wire.

[0038] Please see Figure 1 and Figure 2 The bottom of the cooling tank 1 is provided with a water collection tank 15 and a drain pipe 16. The water collection tank 15 can collect the sprayed cooling water, and the drain pipe 16 can discharge the cooling water in the water collection tank 15 to the outside.

[0039] This embodiment of a cooling device for hot-dip galvanized steel wire production uses equidistantly arranged spray pipes 5 and nozzles 6 to provide comprehensive spray cooling of the galvanized wire. This avoids the need to adjust the position of the spray structure, reduces the workload of workers, and improves the uniformity and effectiveness of the cooling operation. By setting equidistantly arranged guide rollers 2 and installing water-cooling pipes 3 inside the guide rollers 2, the time the galvanized wire spends in the cooling box 1 is extended, further optimizing the cooling effect of the galvanized wire. This solves the problems of existing cooling devices requiring adjustment of the spray structure position, which is laborious, and resulting in short cooling time and poor cooling effect for the galvanized wire.

[0040] It should be noted that the top of the top cover 4 is equipped with a handle, which makes it easy to open and close the top cover 4. Bolts are provided at the four corners of the top cover 4, which are used to fix the top cover 4 and the cooling box 1, thereby increasing the stability of the device during the cooling operation.

[0041] The working principle of the above embodiments is as follows:

[0042] The galvanized wire can be spirally passed through the dividing groove 9 on the guide roller 2, increasing the stroke of the galvanized wire in the cooling box 1, thereby increasing the time for the galvanized wire to be sprayed and cooled. When laying and installing the galvanized wire, first remove the bolts on the top cover 4 to remove the bolts' positioning restriction on the top cover 4. Then push the top cover 4 and move it to one side using the T-shaped sliding plate 14 and T-shaped sliding groove 13. Then the galvanized wire can be installed and laid. After the galvanized wire is installed, move the top cover 4 back and start the external equipment to convey the galvanized wire. Cooling water can be injected into the second water inlet pipe 8. Cooling water enters the spray pipe 5 through the first inlet pipe 7 and is finally sprayed down through the nozzle 6 to cover and cool the galvanized wire below. The sprayed cooling water falls into the water collection tank 15 and is finally discharged through the drain pipe 16. The two ends of the water cooling pipe 3 can be connected to the external water pipe, and then cooling water can circulate inside the water cooling pipe 3. During the process of the galvanized wire being conveyed close to the steering roller 2, heat will be transferred to the cooling water through the steering roller 2 and the water cooling pipe 3. The cooling water transfers the heat, further optimizing the cooling effect of the galvanized wire and reducing the burden of subsequent cooling operations.
