[0026] The following will be combined with 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 of 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.

[0027] like Figure 1~Figure 4 As shown, this embodiment provides an aerosol cooling device for galvanized steel strip, comprising:

[0028] A housing 1 and a pair of inlets and outlets 2, wherein the inlets and outlets 2 are provided on two side surfaces of the housing 1;

[0029] An exhaust purification component 5, the exhaust purification component 5 is arranged on the top of the housing 1;

[0030] An aerosol cooler 3, which is mounted on the top of the housing 1;

[0031] A cooling treatment component 4 is arranged inside the shell 1. The cooling treatment component 4 includes an air cavity plate 4-1, which is fixed to the top of the shell 1. A pair of conveying rollers 4-2 are installed at both ends of the bottom of the shell 1. The air cavity plate 4-1 is located between the conveying rollers 4-2 on both sides. Both ends of the bottom of the shell 1 are fixedly connected to a support seat 4-3. Both ends of the support seat 4-3 are installed with a pair of telescopic cylinders 4-4. The output end of the telescopic cylinder 4-4 is connected to a side frame 4-5. A pair of circular grooves 4-6 are opened on the surface of the side frame 4-5. Support rollers 4-7 are rotatably connected in the circular grooves 4-6. A bottom cover 4-8 is fixedly connected to the surface of the support seat 4-3. A plurality of air holes 4-9 are opened on the top of the bottom cover 4-8. A through groove is opened on the side surface of the side frame 4-5. The through groove movable set is connected to the outside of the bottom cover 4-8. The bottom cover 4-8 and the air cavity plate 4-1 are both connected to the output end of the aerosol cooler 3.

[0032] In this embodiment, in order to achieve efficient cooling treatment effect of the steel strip through aerosol, a cooling treatment component 4 is designed, and two groups of conveying rollers 4-2 are arranged inside the shell 1. The conveying rollers 4-2 are used to actively rotate to convey the steel strip. A support seat 4-3 is arranged on one side of the inlet and outlet 2 inside the shell 1. Telescopic cylinders 4-4 are arranged on both sides of the support seat 4-3. The output end of the telescopic cylinder 4-4 is connected to the side frame 4-5. The side frame 4-5 is used to support the steel strip. A circular groove 4-6 is opened on the surface of the side frame 4-5 and a supporting roller 4-7 is installed, which can play a supporting role in conjunction with the movement of the steel strip and leave a gap in the middle of the steel strip. A bottom cover 4-8 with air holes 4-9 is also provided on the surface of the support seat 4-3, and an air cavity plate 4-1 is provided on the top. The bottom cover 4-8 and the air cavity plate 4-1 both convey aerosol through the aerosol cooler 3 and directly cover the surface of the steel strip being conveyed, so as to achieve a rapid cooling effect.

[0033] Furthermore, the exhaust purification component 5 includes a filter purifier 5-1, which is installed on the top of the outer shell 1. Air collecting hoods 5-2 are provided at both ends of the top of the outer shell 1. The air collecting hood 5-2 is connected to the inside of the outer shell 1. A suction fan 5-3 is installed at the air inlet end of the filter purifier 5-1, and the suction fan 5-3 is connected to the air collecting hood 5-2. A transverse pipe 5-4 is connected between the air collecting hoods 5-2.

[0034] In this embodiment, in order to achieve the effect of sucking out the excess mist inside the shell 1 and accelerating the replacement of new mist, an exhaust purification component 5 is designed. A filter purifier 5-1, a suction fan 5-3 and an air collecting hood 5-2 are arranged on the top of the shell 1. The gas inside the shell 1 can be sucked outward through the air collecting hood 5-2 by the suction fan 5-3, and after suction, the gas can enter the filter purifier 5-1, and the gas is filtered and purified and then dispersed to the outside, and the exhaust mist is discharged, so that new mist can enter in time to maintain the cooling effect.

[0035] Furthermore, both ends of the air cavity plate 4 - 1 are bent upward to form an inclined structure.

[0036] In this embodiment, the outwardly bent inclination angle enables the gas mist dispersed downward by the air cavity plate 4 - 1 to fully cover the surface of the steel strip, thereby ensuring the cooling effect.

[0037] Furthermore, an observation window 6 is opened on the top of the shell 1, and the gas collecting hood 5-2 is located on both sides of the observation window 6.

[0038] In this embodiment, the internal processing conditions can be observed at any time through the observation port, and because it is located on both sides of the gas collecting hood 5-2, there is relatively less gas mist, which is convenient for observation.

[0039] Furthermore, the conveying roller 4 - 2 is a rubber roller with an anti-slip effect.

[0040] In this embodiment, the rubber roller can make the conveying roller 4 - 2 keep in contact with the surface of the steel strip and provide an anti-slip effect without damaging the surface of the steel strip.

[0041] When the strip is cooled, the strip is placed at the inlet and outlet 2 and enters between the conveying rollers 4-2. Then, the telescopic cylinder 4-4 is started, and the position of the side frame 4-5 is adjusted to fit as closely as possible to both sides of the strip. The aerosol cooler 3 is started, and the aerosol is injected into the air cavity plate 4-1 and the bottom cover 4-8. The aerosol is dispersed outwards through the air holes 4-9 to the surface of the strip during transportation. The strip is cooled during transportation. When the internal aerosol reaches a certain amount, the suction fan 5-3 is started, and the excess aerosol is extracted through the air collecting hood 5-2 into the filter purifier 5-1. The aerosol is discharged after being treated, and the internal cooling treatment can be checked through the observation window 6 during the process.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
