[0002] Hot-dip galvanizing, also known as hot-dip galvanizing or hot-dip galvanizing, is an effective way to prevent metal corrosion. It is mainly used in metal structural facilities in various industries. It is to immerse the rust-free steel parts in molten zinc liquid at about 500℃ to make the surface of the steel parts adhere to the zinc layer, thereby achieving the purpose of corrosion prevention. Hot-dip galvanizing needs to be cooled during the production process, usually by water cooling or air cooling.

[0003] In reality, hot-dip galvanizing must be cooled after galvanizing. However, when cooling, it is usually done by blowing air. Generally, a fan is simply used to directly blow air to cool the galvanized parts, but this air cooling effect is poor.

[0004] Therefore, it is necessary to propose a cooling device for hot-dip galvanizing to solve the above problems. Utility Model Content

[0009] Preferably, a trapezoidal groove is penetrated through one end of the cooling box, a trapezoidal sliding block is slidably provided inside the trapezoidal groove, and a plurality of hooks are fixedly provided at the lower end of the trapezoidal sliding block.

[0010] Preferably, a driving motor is fixedly provided at one end of the extension plate corresponding to the central rod, and an output end of the driving motor is fixedly connected to one end of the central rod.

[0011] Preferably, the exhaust hose approaches the eccentric wheel due to wind pressure.

[0012] Preferably, the air outlet of the exhaust hose faces the corresponding air guide hole.

[0013] Preferably, the plurality of air outlets of the exhaust hoses are arranged in a wave shape.

[0014] Technical effects and advantages of the utility model:

[0015] 1. Through the exhaust hoses that are staggered and arranged in opposite directions, when cooling the galvanized parts in the middle, the cooling efficiency of the galvanized parts can be improved through the two-way wind force, and the cooling of the galvanized parts can be refined. And through the setting of the air guide holes, the wind energy blown out by the exhaust hoses can be released to prevent the wind energy from contacting the inner wall of the cooling box and flowing back, resulting in wind convection;

[0016] 2. By setting up multiple eccentric wheels, when the center rod rotates, the eccentric wheels can drive the air outlets of multiple exhaust hoses to swing, thereby further improving the cooling effect.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] A trapezoidal groove 11 is formed through one end of the cooling box 1 , a trapezoidal slider 12 is slidably disposed inside the trapezoidal groove 11 , and a plurality of hooks 13 are fixedly disposed at the lower end of the trapezoidal slider 12 .

[0025] By staggering the exhaust hoses 10 in opposite directions, when cooling the galvanized parts in the middle, the cooling efficiency of the galvanized parts can be improved through the bidirectional wind force, and the cooling of the galvanized parts can be refined. The wind energy blown out by the exhaust hoses 10 can be released through the setting of the air guide holes 2, so as to prevent the wind energy from contacting the inner wall of the cooling box 1 and flowing back, resulting in wind convection.

[0026] The wind discharged from the exhaust hose 10 first contacts the hot galvanized parts, which results in the air molecules in the wind having a large thermal energy, affecting the heat dissipation of the galvanized parts. The air guide holes 2 prevent the hot wind and the newly discharged cold wind from convection, thus affecting the cooling effect.

[0027] A plurality of extension plates 4 are fixedly provided on the inner side of the cooling box 1, a center rod 5 is rotatably provided on one side corresponding to two extension plates 4, a plurality of eccentric wheels 6 are fixedly provided on the outer side of the center rod 5, and the rotation angles of the plurality of eccentric wheels 6 are gradually increased.

[0028] A driving motor 7 is fixedly provided at one end of the extension plate 4 corresponding to the center rod 5. The driving motor 7 is a servo motor, which is a common technology in the prior art and will not be described in detail here. The output end of the driving motor 7 is fixedly connected to one end of the center rod 5.

[0029] By setting a plurality of eccentric wheels 6, when the central rod 5 rotates, the eccentric wheels 6 drive the air outlets of the plurality of exhaust hoses 10 to swing, thereby further improving the cooling effect. By setting the eccentric wheels 6 at different initial rotation angles, it is possible to prevent the galvanized parts from shaking more greatly due to wind concentration, and to increase the blowing range.

[0030] The air outlets of the plurality of exhaust hoses 10 are arranged in a wave shape, so that the blowing range of the exhaust hoses 10 is increased and can be changed at any time.

[0031] Working principle: The operator suspends the galvanized parts that need to be cooled by the hook 13, and then slides the trapezoidal slider 12 in the trapezoidal groove 11 to fix the galvanized parts, and then moves the galvanized parts between the exhaust hoses 10, and then turns on the air pump, so that the air pump transmits wind into the ventilation pipe 9 through the cooling air duct 3, and then blows air toward the galvanized parts through multiple exhaust hoses 10 to cool the galvanized parts, and exhausts the hot air passing through the galvanized parts through the air guide holes 2;

[0032] When the air pump is turned on, the drive motor 7 is turned on, so that the drive motor 7 drives the center rod 5 to drive the eccentric wheel 6 to rotate, so that the eccentric wheel 6 squeezes the exhaust hose 10 to move, and the exhaust hose 10 rotates with the ventilation pipe 9 as the center, so that the direction of the air outlet of the exhaust hose 10 changes, and the air outlet range of the exhaust hose 10 is increased by the setting of the eccentric wheel 6.
