Description

Technical Field

[0001] This utility model belongs to the field of glass tempering technology, specifically relating to a backflow-proof glass tempering cooling device and a glass tempering production line. Background Technology

[0002] Glass tempering cooling equipment typically uses a large air supply unit. The power of the large air supply unit must meet the air supply requirements of the entire equipment, resulting in extremely high noise levels during operation. It is also inconvenient to control the air pressure of glass with different tempering blowing requirements. In addition, the pipeline between the large air supply unit and the air grille is usually more than 5 meters long, resulting in significant air pressure loss in the pipeline. In order to ensure that the air pressure at the air grille outlet can meet the requirements for glass cooling and tempering, the power of the air supply unit must be increased, which will further increase noise and energy consumption.

[0003] The existing technology CN204529655U mentions that in order to facilitate the control of each flat air grating, a variable frequency axial flow air supply unit can be directly installed at the end of each flat air grating. Although the air pressure loss is small, the cooling air will absorb the heat of the glass after cooling the hot glass and become hot air. After the hot air diffuses around the cooling equipment, it will directly enter the flat air grating through the variable frequency axial flow air supply unit, resulting in reduced cooling efficiency and poor tempering effect. Utility Model Content

[0004] The purpose of this utility model is to provide a backflow prevention glass tempering cooling equipment and a glass tempering production line. The glass tempering cooling equipment has the characteristics of low wind pressure loss, low equipment energy consumption, and low equipment noise. It can also prevent the backflow of hot air after cooling, thereby ensuring cooling efficiency and tempering effect.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a backflow prevention glass tempering and cooling device, comprising multiple air grating groups, a glass conveying mechanism, and an air supply unit. The multiple air grating groups include multiple upper air grating groups and multiple lower air grating groups. The glass conveying mechanism is disposed between the multiple upper air grating groups and the multiple lower air grating groups. The multiple air supply units are disposed on one side of the glass conveying direction and connected to the multiple air grating groups. An anti-wind disturbance device is also provided between the multiple air supply units and the multiple air grating groups. The anti-wind disturbance device is used to prevent the hot air generated during the cooling of hot glass from flowing back to the air inlet of the air supply unit.

[0006] Optionally, the wind-resistant device is parallel to the glass conveying direction.

[0007] Optionally, the wind protection device is installed perpendicular to the horizontal plane.

[0008] Optionally, the wind-resistant device is positioned above the top of the plurality of wind grating groups.

[0009] Optionally, the length of the anti-wind disturbance device is greater than or equal to the length of the distribution range of the plurality of wind grating groups along the glass conveying direction.

[0010] Furthermore, the air outlet of the air supply unit and the air inlet of the corresponding air grating group are connected by a ventilation component. The wind protection device is a windbreak plate or windbreak wall with through holes. The through holes are used to allow the ventilation component to pass through and be fixed. The number of through holes is equal to the number of ventilation components.

[0011] Furthermore, the ventilation component is provided with an air distribution plate, which is a plate-shaped object with a plurality of air distribution holes evenly distributed, and the air distribution plate is disposed in the ventilation component close to the air grid assembly.

[0012] Optionally, at least one of the air supply units is connected to at least two of the air grating groups via an air collection box, which is disposed between the wind disturbance prevention device and the plurality of air grating groups.

[0013] Optionally, at least one of the air supply units is connected to at least two wind grating groups via an air collection box, with the air collection box serving as the wind disturbance prevention device between the air supply unit and the corresponding wind grating group.

[0014] A glass tempering production line includes a heating furnace and a cooling device, wherein the cooling device is a backflow prevention glass tempering cooling device as described above.

[0015] The beneficial effects of this utility model are: this utility model uses multiple air supply units to replace a large air supply unit, reducing equipment operating noise; the distance between the multiple air supply units and the air grid group is relatively close, reducing the wind pressure loss between the air supply units and the air grid group, resulting in low equipment energy consumption; furthermore, an anti-wind disturbance device is set between the air supply units and the air grid group to block the hot air after cooling the glass from returning to the air inlet of the air supply unit, so that the air supply unit always provides cold air, improving the glass cooling efficiency and ensuring the glass tempering effect.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention in any way.

[0022] Example 1: As Figure 1-3 As shown, a backflow prevention glass tempering and cooling device includes multiple air grating groups, a glass conveying mechanism 3, and an air supply unit 4. The multiple air grating groups include multiple upper air grating groups 1 and multiple lower air grating groups 2 arranged vertically, sequentially along the glass conveying direction. The glass conveying mechanism 3 is located between the multiple upper air grating groups 1 and the multiple lower air grating groups 2 and is used to convey glass. The glass conveying mechanism 3 can be a roller conveyor mechanism commonly used in the glass processing field, therefore its structure will not be described in detail.

[0023] The upper windshield assembly 1 and the lower windshield assembly 2 have the same structure. Taking the upper windshield assembly 1 as an example, its structure is as follows: Figure 2 As shown, it includes multiple air grating units 7. The air grating unit air inlet 8 of the multiple air grating units 7 in each upper air grating group 1 is connected to the air grating group air inlet 9 of the upper air grating group 1, and air is supplied to each air grating unit 7 through the air grating group air inlet 9.

[0024] Multiple air supply units 4 are arranged on one side of the glass conveying direction and connected to multiple air grating groups. The connection method can be set according to actual needs. For example, the air outlet of one air supply unit 4 can be connected to the air inlet 9 of one air grating group, that is, the number of air supply units 4 and air grating groups corresponds one-to-one, which is a one-to-one connection; or the air outlet of one air supply unit 4 can be connected to the air inlets 9 of at least two air grating groups, that is, the number of air supply units 4 is less than the number of air grating groups, which is a one-to-many connection; or a portion of the air supply unit 4's air outlets can be connected one-to-one with a portion of the air grating group's air inlets 9, while the air outlets of another portion of the air supply unit 4 are connected to the air grating group's air inlets 9 of the remaining air grating groups in a one-to-many manner. The air supply unit 4 can be a fan, air compressor, or air pump. Preferably, in this embodiment, the air supply unit 4 is a centrifugal fan.

[0025] The air outlet of the air supply unit 4 is equipped with a ventilation component 10, which is used to connect to the air inlet 9 of the air grating group. Since there are various ways to connect the air supply unit 4 and the air grating group, there are also various types of ventilation components 10. When the air supply unit 4 and the air grating group are connected one-to-one, the ventilation component 10 is a single-channel pipe. When the air supply unit 4 and the air grating group are connected one-to-many, the air supply unit 4 needs to supply air to two or more air grating groups simultaneously. Therefore, the ventilation component 10 has multiple air outlet channels near the end of the air grating group, and each air outlet channel is connected to a corresponding air grating group.

[0026] Furthermore, such as Figure 3 As shown, the ventilation component 10 is also provided with an air distribution plate 11. The air distribution plate 11 is a plate-shaped object with a plurality of air distribution holes 12 evenly opened. The plurality of air distribution holes 12 on the air distribution plate 11 can make the air supplied by the air supply unit 4 blow more evenly to the air grid assembly.

[0027] In other embodiments, the ventilation component 10 is equipped with a valve, which can be a sliding or rotary type. The valve can control the opening size of the ventilation component 10, thereby regulating the flow rate. In other embodiments, the ventilation component 10 is equipped with a wind pressure sensor to detect the wind pressure inside the ventilation component 10, thereby further precisely controlling the operating power of the air supply unit 4 based on the wind pressure.

[0028] In this embodiment, multiple air supply units 4 are used instead of one large air supply unit, which can reduce equipment operating noise. The multiple air supply units 4 are closer to the air grid assembly, resulting in less air pressure loss and lower equipment energy consumption.

[0029] During the tempering process of hot glass by blowing air through the cooling equipment, the air blown out by the air grid unit 7 absorbs heat from the hot glass after cooling it, increasing the air temperature and forming hot air at a higher temperature. While using multiple air supply units 4 and placing them close to the air grid assembly can reduce air pressure loss, the close proximity means that the exhausted hot air is easily drawn into the air inlet of the air supply unit 4 and blown onto the glass surface through the air grid unit 7, reducing the glass's cooling efficiency and damaging the tempering effect.

[0030] To address this issue, this utility model further proposes to install an anti-wind disturbance device between multiple air supply units 4 and multiple wind grating groups. For example... Figure 1 As shown, the windbreak device can be a windbreak plate 5 or a windbreak wall, with through holes 6 provided on the windbreak plate 5 or windbreak wall. The ventilation component 10 is inserted and fixed in the through holes 6. The number of through holes 6 on the windbreak plate 5 or windbreak wall corresponds to the number of ventilation components 10, that is, the number of air supply units 4. After the windbreak device is installed, it can prevent the hot air after cooling the glass from returning to the air inlet of the air supply unit 4, so that the air supply unit 4 always provides cold air to the air grid assembly, improving the glass cooling efficiency and improving the glass tempering effect.

[0031] Furthermore, the anti-wind disturbance device is parallel to the glass conveying direction, meaning its length is parallel to the glass conveying direction. This maximizes the effective wind-blocking area of ​​the anti-wind disturbance device, further enhancing its wind-blocking effect. The anti-wind disturbance device is also installed perpendicular to the horizontal plane, meaning it is vertically positioned on the ground. This arrangement further improves its wind-blocking effect. The anti-wind disturbance device is positioned above the top of the multiple air grating groups. Since the hot air after cooling the glass typically exits the air grating groups through the gaps between the air grating units 7, the hotest air is concentrated above and below the air grating groups. Therefore, the height of the anti-wind disturbance device above the top of the air grating groups effectively prevents hot air from flowing back to the air supply unit 4. The length of the anti-wind disturbance device is greater than or equal to the distance between the front and rear ends of the multiple air grating groups along the glass conveying direction, ensuring its sufficient length to further enhance the wind-blocking effect.

[0032] In this embodiment, the wind protection device is a windbreak panel or a windbreak wall. The windbreak wall can be a single structure or a splicing of multiple small windbreak panels.

[0033] Alternatively, in other embodiments, the windbreak panel or windbreak wall can be directly used as one side of the fan room, that is, the fan room is directly constructed using the windbreak panel or windbreak wall, so as to reduce the construction cost of the fan room.

[0034] In this embodiment, no air collection box is provided between the air supply unit 4 and the air grid group; the air outlet of the air supply unit 4 and the air inlet 9 of the air grid group are directly connected by the ventilation component 10. In other embodiments, at least one air supply unit 4 is connected to at least two air grid groups via an air collection box, and the air collection box is located between the anti-wind disturbance device and multiple air grid groups, and is positioned closer to the air grid groups. The air collection box allows the air from the air supply unit to be more rationally distributed to the multiple air grid groups connected to it, and the closer the air collection box is to the air grid groups, the better the air distribution effect of the air collection box. Alternatively, after setting the air collection box, multiple air collection boxes can be arranged closely to block the backflow of hot air, forming the aforementioned anti-wind disturbance device. Alternatively, when some air supply units and air grid groups are provided with air collection boxes, and others are not, the air collection box in the part with the air collection box can serve as an anti-wind disturbance device between the air supply unit and the corresponding air grid group; in the part without the air collection box, a windbreak plate or windbreak wall can be used as an anti-wind disturbance device.

Those skilled in the art should understand that modifications or equivalent substitutions can be made to the specific implementation of this utility model with reference to the above embodiments. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model are within the protection scope of the pending claims.
