Description

Technical Field

[0001] This utility model relates to the field of glass tempering technology, specifically to a glass tempering quenching system with a follow-up air blowing mechanism. Background Technology

[0002] To complete the tempering process, the glass tempering unit needs to heat the glass to a certain temperature and then allow it to enter the air grid for rapid cooling. Currently, the tempering glass cooling process is mainly based on air cooling, so a blowing quenching system needs to be configured in the tempering unit.

[0003] In the tempered glass production process, the cooling air pressure required for tempering thick glass is lower, and the corresponding fan power is also smaller, while the cooling air pressure required for tempering thin glass is higher, and the fan power is larger. Therefore, for a piece of equipment to simultaneously produce both thick and thin tempered glass, the fan power usually needs to be configured according to the air pressure required for producing the thinnest glass. When producing thick glass, because the tempering of thick glass requires low air pressure and a long time, it is necessary to achieve tempering by blowing a smaller airflow for a long time, which usually requires the fan to operate at a reduced frequency. On the other hand, the tempering of thin glass requires high air pressure and a short time, which requires the tempering to be completed in a short time with higher air pressure, which usually requires the fan to operate at a high frequency. If high-pressure blowing continues after the thin glass has been tempered, it will lead to a significant increase in equipment energy consumption. Utility Model Content

[0004] Based on the technical problems existing in the prior art, the purpose of this utility model is to propose a glass tempering and quenching system with follow-up air blowing.

[0005] The technical solution adopted by this utility model is: a glass tempering and quenching system with follow-up air blowing, including a fan unit, the air outlet of the fan unit is connected to the air inlet of a first air collecting box, a second air collecting box is connected to the side of the first air collecting box, the first air collecting box and the second air collecting box are respectively connected to air grids for blowing air onto the glass, and a first gate valve with controllable opening is provided between the first air collecting box and the second air collecting box. By adjusting the opening of the first gate valve, the air pressure ratio of the first air collecting box and the second air collecting box can be controlled.

[0006] As a preferred embodiment, the first and second air collection boxes supply air to the left and right sections of the air grid, respectively.

[0007] As a preferred embodiment, a second gate valve is provided between the first air collecting box and the air grid, and the opening and closing of the second gate valve is used to control the connection or closure of the first air collecting box and the air grid.

[0008] As a preferred embodiment, a drive unit for controlling the opening degree of the first gate valve and the second gate valve is also provided.

[0010] As a preferred embodiment, the second air collection box is equipped with several air pressure gauges for detecting the air pressure of the second air collection box.

[0011] The beneficial effects of this utility model are: This invention utilizes a single fan unit to supply air to a first and second interconnected air collection box. A controllable first valve is installed between the two air collection boxes, and the air pressure of the two air collection boxes is controlled by adjusting the opening of the first valve.

[0015] The present invention will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures and features in one embodiment may be advantageously incorporated into other embodiments.

[0016] To more clearly describe a glass tempering and quenching system with a follow-up airflow, combined with the attached... Figure 1 Detailed description is as follows: like Figure 1As shown, a glass tempering and quenching system with follow-up air blowing (hereinafter referred to as the quenching system) is provided at both ends of the quenching system, which is equipped with a heating furnace 8 and a sheet unloading platform 9 respectively. The glass to be tempered is sequentially fed to the heating furnace 8, the quenching system and the sheet unloading platform 9 through a conveyor roller to complete the tempering and conveying of the glass. The quenching system includes a fan unit 1 for providing cooling air. The straight arrow in the figure indicates the direction of cooling air delivery. The air outlet of the fan unit 1 is connected to the air inlet of the first air collecting box 2. The air outlet of the first air collecting box 2 is connected to the air grid 4. The air grid 4 is used to blow cooling air to the glass to be tempered. A second gate valve 7 is provided between the air grid 4 and the first air collecting box 2. The gate valve is a gate valve with controllable opening, which is used to control the connection or closure of the first air collecting box 2 and the air grid 4. When the gate valve is open, the first air collecting box 2 sends air to the air grid 4; when the gate valve is closed, the first air collecting box 2 stops sending air to the air grid 4.

[0017] Furthermore, the fan unit 1 can be a single fan or a combination of multiple fans connected in series, in parallel, or in a series-parallel connection.

[0018] In this embodiment, a second air collecting box 5 is provided on the side of the first air collecting box 2 and communicates with it. The air outlet of the second air collecting box 5 is connected to the air grid 4. A first gate valve 3 with controllable opening is provided between the first air collecting box 2 and the second air collecting box 5. When the first gate valve 3 is fully open, the airflow channel between the first air collecting box 2 and the second air collecting box 5 is completely unobstructed, and the air pressure of the two air collecting boxes tends to be the same. When the first gate valve 3 is partially open, the airflow from the first air collecting box 2 to the second air collecting box 5 is obstructed, resulting in the air pressure of the second air collecting box 5 being less than the air pressure of the first air collecting box 2.

[0019] Furthermore, when the second air collector 5 supplies air to the air grid 4, the right section of the air grid 4 blows out cooling air; when the first air collector 2 supplies air to the air grid 4, the left section of the air grid 4 blows out cooling air; when the first air collector 2 and the second air collector 5 supply air to the air grid 4 at the same time, the left and right sections of the air grid 4 respectively output cooling air with the same air pressure as the corresponding air collector. Specifically, the left section of the air grid 4 is closer to the heating furnace 1, and the right section of the air grid 4 is farther away from the heating furnace 1.

[0020] Furthermore, the position of the first gate valve 3, the number of air outlets of the first air collection box 2, and the number of the first gate valve 3 and the second gate valve 7 can all be adjusted according to the actual glass processing requirements.

[0021] Furthermore, both the first air collecting box 2 and the second air collecting box 5 are connected to independent air grilles 4, and the main drives of each air grille 4 can be synchronously linked or move independently.

[0022] In this embodiment, several air pressure detectors 6 are installed on the second air collection box 5 to monitor the air pressure inside the second air collection box 5 in real time, and adjust the opening of the first gate valve 3 according to the detection results, so that the air pressure of the first air collection box 2 and the second air collection box 5 both meet the process requirements, thereby ensuring that the air grid 4 outputs suitable cooling air and ensuring the cooling quality of the tempered glass.

[0023] In this embodiment, a drive unit is also provided, which is used to control the opening degree of the first gate valve 3 and the second gate valve 7. The drive unit is automatically controlled, such as a motor, electric cylinder, pneumatic cylinder, electric push rod, etc. The first gate valve 3 and the second gate valve 7 can share a drive unit, or they can be provided with independent drive units. Of course, the opening degree of the first gate valve 3 and the second gate valve 7 can also be manually adjusted by the operator.

[0024] The working principle of the glass tempering and quenching system with follow-up air blowing according to this utility model is as follows: When cooling thicker tempered glass, the required tempering air pressure is relatively low and the blowing time is relatively long, and the fan needs to operate at a low frequency. After the glass comes out of the heating furnace 1, it enters the quenching stage. At this time, the first gate valve 3 and the second gate valve 7 are fully opened to allow the airflow between the first air collection box 2 and the second air collection box 5 to be unobstructed. The fan is started to deliver cooling air. Since there is no obstruction between the first air collection box 2 and the second air collection box 5, after the cooling air enters the first air collection box 2 and the second air collection box 5, the air pressure of the two air collection boxes is consistent. Then the cooling air is blown onto the glass surface through the air grid 4 to achieve tempering.

[0025] When cooling thin tempered glass, higher tempering air pressure and shorter blowing time are required, and the blower needs to operate at high frequency. After the glass comes out of the heating furnace 1, it enters the quenching stage. The blower is started to deliver cooling air. At this time, the second gate valve 7 is fully opened to ensure that the left section of the air grid 4 outputs high-pressure air, so that the glass has completed tempering after passing through the blowing area of ​​the left section of the air grid 4. At the same time as the second gate valve 7 is opened, the first gate valve 3 needs to be partially opened to allow a small amount of cooling air to enter the second air collection box 5, ensuring that the left section of the air grid 4 outputs high-pressure air and the right section outputs low-pressure air, so that the glass will not bend when it enters the blowing area of ​​the right section of the air grid 4. By reducing the unnecessary high-pressure blowing time of the glass, energy waste is reduced.

[0026] When cooling glass of different thicknesses, the second gate valve 7 can be closed and the fan frequency adjusted when the glass leaves the blowing area of ​​the left section of the air grating 4, so that the air pressure of the second air collection box 5 meets the processing requirements of the corresponding glass. Only the right section of the air grating 4 connected to the second air collection box 5 is allowed to continue blowing, thereby further achieving energy saving.

[0027] The parts not described in detail in this embodiment are existing technologies.

[0028] It should be noted that although the present invention has been described through the above embodiments, the present invention may have other various embodiments. Without departing from the spirit and scope of the present invention, those skilled in the art can obviously make various corresponding changes and modifications to the present invention, but these changes and modifications should all fall within the scope of protection of the appended claims and their equivalents.
