Description

Technical Field

[0001] The utility model relates to the technical field of glass tempering, in particular to an air grille unit and an air grille for glass tempering. Background Art

[0002] Currently, wind grilles used in glass tempering, whether flat or curved, mostly adopt an integrated blowing method. For example, the glass graded tempering furnace disclosed in application number CN202011309297.1 mostly uses large fans for integrated air supply. The wind grille blowing can only be adjusted as a whole. Moreover, due to the complex air path of the large fan, the wind path loss is high, resulting in a large waste of resources. In addition, the integrated air supply method requires high fan power and a long air path from the fan to the wind grille, resulting in poor sensitivity and accuracy in the adjustment of wind grille air volume and air pressure, which cannot further improve the quality of glass tempering. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a wind grid unit and wind grid for glass tempering, which abandons the complex air path system and divides the wind grid into multiple wind grid units that can be controlled and adjusted individually to achieve efficient and accurate air supply. The wind grid composed of the wind grid units can achieve energy saving and consumption reduction in glass tempering, and at the same time can further improve the quality of tempered glass.

[0004] In order to achieve the above technical purpose, the technical solution adopted is: a wind grid unit for glass tempering is provided with a bellows, an air inlet is provided on the side of the bellows facing away from the glass, and an air outlet is provided on the side facing the glass. Several wind knives for blowing cold air to the glass are installed at the air outlet, and the air inlet is connected to the air supply assembly through a blowing valve group. The air supply assembly includes an independent fan and a connecting pipe. The connecting pipe is respectively connected to the independent fan and the air inlet to realize direct connection between the independent fan, the bellows and the wind knife. An exhaust channel for discharging hot air is provided between two adjacent wind knives, and the exhaust outlet of the exhaust channel runs through the side of the bellows facing away from the glass.

[0005] Beneficial effects: Each wind grid unit has an independent fan, which eliminates the complex wind path system and effectively reduces the wind loss on the wind path; the power of the independent fan is relatively small, and the independent fan is close to the wind knife, so that a single wind grid unit can achieve efficient and precise adjustment; and, compared with the existing technology where most of the wind from the wind knife can only be discharged from both ends, by setting an exhaust channel in the bellows, the heated cold air is discharged from the glass surface, and the unobstructed exhaust does not affect the cooling air, thereby improving the quality of glass tempering.

[0006] Furthermore, the bellows is pyramid-shaped, with the side facing away from the glass being the top of the bellows.

[0007] Beneficial effects: The pyramid-shaped wind box ensures that the cooling air at the air inlet can be quickly transported to the wind knife along the inclined inner wall. The shape of the bottom of the air inlet is rectangular, which is convenient for the splicing and arrangement of the wind grid units.

[0008] Furthermore, the exhaust passage is in an inverted cone shape, with its small end facing the glass.

[0009] Beneficial Effects: The exhaust duct adopts an inverted cone shape, which makes it easier for hot air to diffuse after entering the exhaust inlet, thus facilitating its exhaust. Inside the bellows, the tapered outer wall of the exhaust duct exerts downward pressure on the cooling airflow inside the bellows, forcing the cooling airflow toward the air knife, effectively improving the air supply efficiency of each blowing unit and further achieving the goal of energy conservation and consumption reduction.

[0010] Furthermore, the bellows is equipped with a sensor for detecting actual parameters of glass tempering.

[0011] Beneficial effect: The sensor is set on each wind grid unit. While using the wind grid unit to accurately temper the glass, it can also collect the actual parameters of glass tempering in real time by region, making the detection more accurate.

[0012] Furthermore, the communicating pipe is provided with a connection port for connecting adjacent wind grid units in series to realize wind path interconnection.

[0013] Beneficial effects: Adjacent wind grid units are interconnected through the connection port, and the air volume and wind pressure of a certain wind grid unit can be increased at any time, achieving ultra-high wind pressure in local areas, a wider range of wind pressure adjustment in local areas, and a wider range of tempered glass types.

[0014] A wind grid comprises a plurality of wind grid units, wherein the wind grid units are arranged in an array in a blowing area.

[0015] Beneficial effect: According to the size of the blowing area, multiple wind grid units can be combined and arranged to form a wind grid for glass tempering. The installation and combination are more convenient, the complex wind path system is abandoned, and the floor space is saved. The wind grid composed of the wind grid units uses a direct connection between the fan and the wind grid, eliminates the complex wind path system, reduces the wind loss from the fan to the wind grid, and can achieve energy saving and consumption reduction in glass tempering, improve tempering precision, and improve glass tempering quality. At the same time, for glass of different thickness, shape or size, each wind grid unit can be adjusted separately, and the use of a single fan independent control method can achieve precise and efficient tempering, which can further improve the quality of tempered glass.

[0021] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0024] like Figure 1 As shown, a wind grid unit for glass tempering is provided with a wind box 2. The side of the wind box 2 facing away from the glass is provided with an air inlet 201, and the side facing the glass is provided with an air outlet 202. The air outlet 202 is equipped with a number of wind knives 3 for blowing cold air to the glass. The coverage area of ​​the wind box 2 can be set according to the actual needs of the equipment, and the number of wind knives 3 equipped with a single wind box can also be set according to needs. The wind box 2 is pyramid-shaped, and the side facing away from the glass is the top of the tower, as shown in FIG. Figure 1 The direction shown is the wind grid unit used on the upper wind grid, so the upper smaller part of the wind box 2 is the tower top, and the lower larger part is the tower bottom. If it is used for the lower wind grid, the settings are opposite.

[0025] The wind knife 3 can be set to a plate shape or a box shape. When installed at the air outlet 202, it can cover the air outlet 202. The side of the wind knife 3 corresponding to the glass is the blowing surface. The blowing surface of the wind knife 3 is provided with a cold air blowing port 301 connected to the inner cavity of the bellows 2. The size and shape of the cold air blowing port 301 are not limited and can be designed according to the actual needs of the coverage area equipment. The cold air blowing ports 301 on the blowing surface of the wind knife 3 are arranged in a staggered manner, which can blow tempered air to the glass more evenly. The blowing surface of the wind knife 3 can be designed as a curved surface 302 that is raised toward one side of the glass. The curved surface 302 is composed of a plurality of angled surfaces, and each angled surface is provided with a cold air blowing port 301. The curved surface 302 ensures that the blowing surface is blown at multiple angles, which can ensure that the cooling air blown out by the wind knife can evenly cover every part of the glass.

[0026] like Figure 1 As shown, the air inlet 201 is connected to the air supply component 1 through the blowing valve group 8. The blowing valve group can be automatically controlled by a computer to realize the opening and closing of a single blowing unit. The air supply component 1 includes an independent fan 101 and a connecting pipe 102. The connecting pipe 102 connects the independent fan 101 and the air inlet 201 respectively, realizing a direct connection between the independent fan 101, the bellows 2 and the wind knife 3. The specific structure of the connecting pipe 102 is designed according to the structure of the wind grid. Since the distance between the independent fan 101 and the wind knife 3 is short, the wind path is simple, and the wind loss is small, it is possible to achieve accurate and efficient adjustment of a single blowing unit, thereby achieving the purpose of reducing energy consumption, saving energy and reducing emissions.

[0027] like Figure 2 As shown, the connecting duct 102 is composed of an elbow 1021, a fixing plate 1022, and a connecting nipple 1023. The elbow 1021 is used to connect the independent fan 101 and the connecting nipple 1023. The wind grid unit 7 is fixed to the equipment frame or platform via the fixing plate 1022. The specific number and combination of the connecting duct 102 can be set as needed. The connecting duct 102 can also be a straight pipe or a curved pipe, depending on the designed location of the wind grid unit 7.

[0028] like Figure 2 As shown, an exhaust duct 4 for discharging hot air is provided between two adjacent wind knives 3. The exhaust duct 4 is not connected to the inner cavity of the bellows 2. The exhaust inlet 402 of the exhaust duct 4 is set corresponding to the glass, and the exhaust outlet 401 of the exhaust duct 4 passes through the side of the bellows 2 facing away from the glass. The number of exhaust ducts 4 is set as needed, and their function is to discharge the hot air cooled during tempering from the bottom of the wind grid. The setting direction of the exhaust duct 4 is related to the shape of the glass to be tempered, and the axial direction of the exhaust duct 4 coincides as much as possible with the direction of the hot air rebounding from the glass surface.

[0029] like Figure 3As shown, the exhaust duct 4 is in an inverted cone shape, with its smaller end facing the glass. This structure allows hot air to diffuse more easily after entering the exhaust duct 4, thus facilitating its exhaust. The inner cavity of the bellows 2 is divided by the conical exhaust duct 4. The outer wall of the exhaust duct 4 exerts downward pressure on the cooling airflow inside the bellows 2, forcing the cooling airflow toward the air blades 3. This effectively improves the air supply efficiency of each wind grid unit, further achieving energy conservation and consumption reduction.

[0030] The distance between the exhaust inlet 402 of the exhaust channel 4 and the glass is greater than the maximum distance between the blowing surface of the wind knife 3 and the glass. Figure 2 As shown, when the air grille unit 7 is an upper air grille, the exhaust inlet 402 of the exhaust duct 4 is higher than the blowing surface of the wind knife 3. Through this setting structure, the heated air can flow out of the exhaust duct quickly, avoiding the cold air from being discharged directly from the exhaust duct.

[0031] like Figure 1 As shown, the bellows 2 is equipped with a sensor 5 for detecting actual parameters of glass tempering. The sensor types include wind pressure, air volume sensors, and temperature sensors. The detection probe of the sensor is located between the lower wind knives 3.

[0032] The connecting pipe 102 is provided with a connection port 6 for connecting adjacent wind grid units in series to realize wind path interconnection. Figure 1 As shown, the connecting short section 1023 is connected to the air supply assembly 1 of the adjacent fan unit. The connecting short section 1023 can be as follows: Figure 1 The three-way structure shown can also be a four-way structure, etc., and its function is to connect adjacent wind grid units 7 in series to achieve interconnection of wind paths.

[0033] A wind grid comprises a plurality of wind grid units 7, which are arranged in an array in a blowing area. Figure 4 Taking the flat wind grille shown as an example, the wind grille composed of wind grille units 7 has a flat surface. A 6×4 wind grille unit array is used to achieve independent control of the wind blowing area of ​​each wind grille unit 7, enabling real-time dynamic adjustment of glass tempering parameters at different locations. In the case of a curved wind grille, the wind grille composed of wind grille units 7 has a curved surface.

[0034] The technical means disclosed in the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
