Description

Technical Field

[0001] The utility model relates to the technical field of glass processing equipment, in particular to a nozzle and an air cooling device. Background Art

[0002] The tin bath is the main device for float glass molding. Usually, the tin bath is composed of refractory materials and steel shells to form a tank body for holding the float medium. The outer periphery of the refractory material is supported by the steel shell, while the inner wall of the refractory material is in direct contact with the tin liquid. Since the refractory material will continuously transfer heat to the steel shell during the glass molding process, the steel shell must be cooled and the temperature must be controlled within a certain temperature range. Otherwise, the steel shell will be overheated and deformed, causing the tin liquid to leak.

[0003] However, traditional steel shell cooling is mainly achieved by means of a blower. The blower blows air into the air duct under the steel shell and cools the steel shell through multiple branch pipes. However, the cooling range is not comprehensive enough, which can easily cause the bottom shell of the tin tank to deform or even break. Utility Model Content

[0026] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0027] The traditional circular cooling air nozzle in the prior art has an insufficient cooling range due to its shape. There is a problem that the bottom shell of the tin tank turns red and deforms, and even causes high-temperature radiation fracture, resulting in leakage of tin liquid from the tin tank. Therefore, based on this technical problem, the present application provides a nozzle and an air cooling device, which improves the structure of the cooling air nozzle so that the cooling air can be ejected from the air nozzle in a fan-shaped form, thereby avoiding deformation and fracture of the bottom shell of the tin tank; and by improving the pipeline structure, the pipeline is kept away from the lower surface of the tin tank, reducing the influence of the pipeline on the air flow.

[0028] The present application takes the application scenario of float glass production as an example to introduce the structure of the nozzle and the air cooling device in the present application and the method of using the nozzle and the air cooling device. The nozzle and the air cooling device provided in the present application are not only applicable to float glass production, but also applicable to other application scenarios with cooling blowing and heating blowing requirements, specifically:

[0029] Please refer to Figure 1-3 In one aspect of the present application, a wind cooling device is provided, comprising a nozzle 1 and a ventilation duct 2; the air outlet of the ventilation duct 2 is connected to the air inlet of the nozzle 1; the air inlet of the ventilation duct 2 is used to connect to an air inlet device; wherein the ventilation duct 2 comprises a vertical duct 21 and a connecting elbow 22; the air outlet of the vertical duct 21 is connected to the air inlet of the connecting elbow 22; the air outlet of the connecting elbow 22 is connected to the air inlet of the nozzle 1; the bending angle of the connecting elbow 22 is the same as the angle of the first angle a, and the surface where the air inlet of the connecting elbow 22 is located is parallel to the surface where the air outlet of the nozzle 1 is located; the air outlet of the vertical duct 21 is used to connect to an air inlet device. By making the bending angle of the connecting elbow 22 the same as the angle of the first angle a formed by the nozzle 1, the nozzle 1 can be connected to the vertical duct 21 through the connecting elbow 22, and the use of the vertical duct 21 can reduce the path of gas flow relative to the inclined duct, thereby improving the gas ejection effect.

[0030] In a further embodiment, the vertical pipe 21 is integrally formed with the connecting elbow 22. By integrally forming the vertical pipe 21 and the connecting elbow 22, not only the connection strength between the vertical pipe 21 and the connecting elbow 22 is improved, but also the gas is prevented from flowing out of the gap between the vertical pipe 21 and the connecting elbow 22, thereby reducing gas loss.

[0031] In some embodiments, the main pipe 3 and at least one auxiliary pipe 4 are further included; the air inlet of the auxiliary pipe 4 is connected to the air outlet of the main pipe 3; the auxiliary pipe 4 includes at least one air outlet, and the air outlet of the auxiliary pipe 4 is connected to the air inlet of the vertical pipe 21; the air inlet of the main pipe 3 is used to connect to the air intake device. By providing multiple groups of auxiliary pipes 4 that cooperate with the main pipe 3, and connecting the auxiliary pipes 4 with the air inlets of multiple groups of vertical pipes 21, multiple vertical pipes 21 can be driven to perform blowing work at the same time, thereby improving the working efficiency.

[0032] In a further embodiment, the auxiliary pipes 4 are respectively vertically arranged on both sides of the main pipe 3, and all the auxiliary pipes 4 located on both sides of the main pipe 3 are symmetrically arranged about the main pipe 3, and the auxiliary pipes 4 on both sides are symmetrically arranged about the main pipe 3, so that the gas flow is more uniform and the gas outlet effect is improved.

[0033] Please refer to Figure 4-5 In another aspect of the present application, a nozzle 1 is provided, comprising an oblique groove 11 and a connecting member 12; the air outlet of the connecting member 12 is connected to the air inlet of the oblique groove 11; the air inlet of the connecting member 12 is used to connect to the air inlet device; a first angle a is formed between the surface where the air outlet of the oblique groove 11 is located and the side wall of the oblique groove 11, and the first angle a is an acute angle. By improving the structure of the nozzle 1, the oblique groove 11 is used as the air outlet of the nozzle 1, and an acute angle is formed between the surface where the air outlet of the oblique groove 11 is located and the side wall of the oblique groove 11. When the oblique groove 11 is arranged parallel to the surface to be blown, due to the angle formed between the gas in the oblique groove 11 and the surface to be blown, the cooling wind can be ejected from the nozzle 1 in a fan-shaped manner, and the effect of increasing the ejection range of the cold wind is achieved without increasing the number of nozzles 1, thereby effectively cooling the shell of the tin tank bottom 5 and avoiding deformation and fracture of the shell of the tin tank bottom 5.

[0034] The first angle a is 40°-50°, preferably 45°. By forming an angle of 40°-50°, the fan-shaped surface blown out forms the largest contact surface with the plane of the groove bottom 5, thereby effectively covering the surface to be cooled of the groove bottom 5, achieving an effective cooling effect.

[0035] In some embodiments, a diverter blade 13 is provided in the bevel slot 11; the diverter blade 13 is distributed along the length direction of the bevel slot 11, and the blade end of the diverter blade 13 faces one side of the connecting member 12. The diverter blade 13 diverts the gas in the bevel slot 11, so that the gas is more easily blown out of the bevel slot 11 in a fan-shaped manner, thereby increasing the blowing coverage area.

[0036] In a further embodiment, the splitter blade 13 is centrally arranged in the width direction of the bevel slot 11. By centrally arranging the splitter blade 13, the gas on both sides of the splitter blade 13 is evenly distributed, thereby preventing the gas distribution from failing to achieve an effective air blowing cooling effect.

[0037] In some embodiments, a connecting pipe 14 is further included; one end of the connecting pipe 14 is connected to the air outlet of the connecting member 12; the other end of the connecting pipe 14 is connected to the air inlet of the oblique slot 11. The connecting member 12 is connected to the oblique slot 11 through the connecting pipe 14, which increases the flow distance of the gas in the nozzle 1, so that there is enough distance in the nozzle 1 to divert the gas, thereby improving the gas diversion effect.
