Description

Technical Field

[0001] This invention relates to the technical field of tempering furnace air grid systems, and more particularly to a glass heat treatment mechanism and a glass tempering furnace. Background Technology

[0002] During the tempering process, glass undergoes a heating and cooling phase. In the heating phase, a heating fan draws in room-temperature air into a furnace, heats it, and then blows it onto the glass surface to heat it. However, this method results in high energy consumption for the heating fan. In the cooling phase, a cooling fan draws in room-temperature air and blows it onto the glass surface to lower its temperature. However, the cooled air, due to its contact with the glass, experiences a temperature rise. When this air is released into the atmosphere, it raises the temperature of the air drawn into the cooling fan, reducing the effectiveness of subsequent glass cooling. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a glass heat treatment mechanism that can reduce the energy consumption of glass tempering and improve the cooling effect of glass.

A storage component defines a receiving chamber and a first channel and a second channel connecting to the receiving chamber. The first channel connects to the first opening. A cooling assembly includes a cooling fan grille and a cooling fan. The cooling fan grille is located downstream of the heating furnace and defines a cooling chamber. The cooling chamber has a second opening through which it connects to the cooling fan grille. The cooling fan is connected to the second opening to guide gas into the cooling chamber.

[0007] The glass heat treatment mechanism according to embodiments of the present invention has at least the following beneficial effects: The heating chamber and the receiving chamber are connected by a first channel, allowing the heating fan to directionally draw gas from the receiving chamber into the heating chamber, thereby reducing the energy consumption of the heating fan. Furthermore, after the glass enters the cooling chamber, the cooling fan draws in air to cool the glass surface. The cooled air temperature rises and is conducted to the receiving chamber for storage via a second channel. This portion of air is then conducted to the heating chamber via the first channel for subsequent glass heating, thereby reducing the energy consumption generated by the heating fan and preventing the cooling fan from drawing in high-temperature air, thus improving the glass cooling effect. Simultaneously, the gas is circulated among the heating assembly, the storage component, and the cooling assembly, further reducing the energy consumption of the glass heat treatment mechanism and improving the efficiency of glass tempering.

[0026] The glass heat treatment mechanism of a first aspect embodiment and the glass tempering furnace of a second aspect embodiment of the present invention will now be described with reference to the accompanying drawings. It should be noted that, for ease of description and understanding, in the embodiments of the present invention and the accompanying drawings, the front-to-back direction is indicated as the first direction, and the left-to-right direction is indicated as the second direction. The first and second directions intersect, and the second direction is the direction of glass processing and conveying. In practical applications of glass processing, the first and second directions can also be other directions.

[0027] A first aspect of the present invention provides a glass heat treatment mechanism 100 for tempered glass, see reference. Figures 1 to 4 As shown, the glass heat treatment mechanism 100 includes a heating assembly 110, a storage unit 120, and a cooling assembly 130. The heating assembly 110 includes a furnace 111 and a heating fan 112. The furnace 111 defines a heating chamber 1111, which is connected to the outer wall of the furnace 111 and forms a first opening 1112. The heating fan 112 is located at the first air outlet, allowing heating gas to be delivered to the furnace 111 for heat treatment of the glass. The storage unit 120 defines a receiving cavity 121, and a first channel 122 and a second channel 123 communicating with the receiving cavity 121. The first channel 122 and the second channel 123 are separated. The first channel 122 is connected to the first opening 1112 to connect the receiving cavity 121 and the heating chamber 1111. The heating fan 112 is located between the first opening 1112 and the first channel 122.

[0028] A cooling assembly 130 is positioned downstream of the heating furnace 111 along the glass conveying direction (left-right direction). The cooling assembly 130 includes a cooling fan grille 131 and a cooling fan 132. The interior of the cooling fan grille 131 defines a cooling chamber 1311, which is used to cool the glass to improve its strength. A second opening 1312 is formed in the side wall of the cooling fan grille 131 through the cooling chamber 1311. The cooling fan 132 is positioned at the second opening 1312 to guide external gas into the cooling chamber 1311. A second channel 123 connects to the cooling fan grille 131 to connect the receiving cavity 121 and the cooling chamber 1311. The second channel 123 is separated from the second opening 1312.

[0029] Specifically, in practical applications, the glass is pre-placed in the heating furnace 111. Since the receiving cavity 121 stores gas, when the heating fan 112 is started, the gas in the receiving cavity 121 is conducted through the first channel 122 under the action of the heating fan 112. After the gas is heated, it enters the heating furnace 111 to heat the glass. The first channel 122 reduces the energy consumption of the heating fan 112 in drawing in gas, and because the gas collected in the receiving cavity 121 is hot gas generated during the glass cooling process, the gas temperature inside the receiving cavity 121 is relatively high. Compared to directly drawing in cold air from the external environment for heating, this saves overall heating energy consumption.

[0030] After the glass completes the heating process, it is transported to the cooling chamber 1311 in a left-right direction. At this time, the cooling fan 132 is activated to draw gas from the outside into the cooling chamber 1311. When the gas enters the cooling chamber 1311 and comes into contact with the glass, it will automatically heat up due to the previously heated glass surface. For ease of understanding and description, the gas that has already contacted the glass and achieved cooling is referred to as hot gas. As external gas is continuously drawn in, the hot gas is conducted to the receiving chamber 121 through the second channel 123. The receiving chamber 121 stores this heated gas for use in heating the next piece of glass. This not only reduces the energy consumption of the heating fan 112 in heating the gas, but also allows the gas in the cooling fan 131 to be recycled, improving the processing efficiency of tempered glass. In this embodiment, the cooling fan 132 and the second channel 123 are positioned opposite each other in the front-back direction when connected to the cooling chamber 1311, so that the gas can fully contact the glass for cooling before entering the receiving chamber 121 for storage through the second channel 123.

[0031] During the glass tempering process, in the heating stage, heated air is blown onto the glass surface to heat it evenly to a softened state (but not melted), thus eliminating internal stress. After heating, the glass needs to be cooled. In the cooling stage, room temperature or low temperature gas is blown onto the glass surface to lower its temperature, causing a compressive stress layer to form on the surface and a tensile stress layer to form internally, thereby increasing the glass's strength. The lower the temperature of the cooling air and the faster the cooling rate, the greater the surface stress (compressive stress) of the tempered glass, thus improving its mechanical strength and impact resistance.

[0032] In related technologies, after the heating fan 112 draws in room-temperature gas, it needs to be heated from room temperature. This requires the heating fan 112 to consume a significant amount of energy both to draw in and to heat the gas, resulting in high energy consumption. Furthermore, after the cooling fan 132 draws in gas to cool the glass, the hot gas is discharged into the atmosphere, leading to heat loss and an increase in the temperature of the gas near the heating fan grille. When the cooling fan grille 131 draws in this heated gas, the cooling effect on the glass decreases.

[0033] In this embodiment of the invention, the glass heat treatment mechanism 100 connects the heating chamber 1111 and the receiving chamber 121 via a first channel 122, allowing the heating fan 112 to directionally draw gas from the receiving chamber 121 into the heating chamber 1111, thereby reducing the energy consumption of the heating fan 112. Furthermore, after the glass enters the cooling chamber 1311, the cooling fan 132 draws in air to cool the glass surface. The cooled air temperature rises and is conducted to the receiving chamber 121 via the second channel 123 for storage. This portion of air is then conducted to the heating chamber 1111 via the first channel 122 for subsequent glass heating, thereby reducing the energy consumption of the heating fan 112 and preventing the cooling fan 132 from drawing in high-temperature air, thus improving the glass cooling effect. Simultaneously, the gas is circulated among the heating assembly 110, the storage unit 120, and the cooling assembly 130, further reducing the energy consumption of the glass heat treatment mechanism 100 and improving the efficiency of glass tempering.

[0034] In some embodiments, see Figures 1 to 4 As shown, the storage component 120 also includes a third channel 124, which is connected to the cooling fan grille 131, enabling the receiving cavity 121 and the cooling cavity 1311 to communicate with each other. The third channel 124 and the second channel 123 are arranged on both sides of the cooling fan grille 131 in the front-back direction; that is, the connection points of the third channel 124 and the second channel 123 connecting to the cooling cavity 1311 are arranged opposite each other in the front-back direction. Figure 3 As shown, the connection port of the third channel 124 to the cooling chamber 1311 is defined as the air inlet (second opening 1312), and the connection port of the second channel 123 to the cooling chamber 1311 is defined as the air outlet. The air inlet and outlet are arranged on both sides of the cooling fan grille 131 in the front-to-back direction. This allows gas to be introduced into the cooling chamber 1311 from the receiving chamber 121 through the third channel 124, and then returned to the receiving chamber 121 from the cooling chamber 1311 through the second channel 123. The cooling fan 132 is located between the second opening 1312 and the third channel 124.

[0035] Specifically, the receiving cavity 121 stores gas. After the glass completes the heating process, it is transported to the cooling cavity 1311. At this time, the third channel 124 connects the receiving cavity 121 and the cooling cavity 1311. The gas in the receiving cavity 121 is directionally transported to the cooling cavity 1311 by the cooling fan 132, thereby reducing the energy consumption of the cooling fan 132 in introducing gas into the cooling cavity 1311. The gas undergoes preliminary cooling by the cooling fan 132 and then enters the cooling cavity 1311 to cool the glass. The cooled gas exchanges heat with the glass, and its own temperature rises to form hot gas, which is then discharged from the second channel 123. Since the other side of the cooling cavity 1311 is connected to the receiving cavity 121 through the second channel 123, the hot gas is then recycled back into the receiving cavity 121 for storage for subsequent glass heating, reducing the amount of air that the subsequent heating fan 112 needs to reheat and lowering the overall energy consumption of the glass heat treatment mechanism 100.

[0036] In some embodiments, see Figures 1 to 7 As shown, the cooling assembly 130 also includes a cooling element 133, which has a cooling chamber 1333 inside. The cooling chamber 1333 is used to further cool the air entering the cooling chamber 1311. The cooling element 133 has an air inlet channel 1331 and an air outlet channel 1332. An airflow circulation path can be formed between the cooling chamber 1333 and the cooling chamber 1311 through the air inlet channel 1331 and the air outlet channel 1332. Specifically, the cooling fan 132 introduces air from the outside (the housing 121 or the atmospheric environment) and inputs it into the cooling chamber 1333 through the air inlet channel 1331. After the air undergoes preliminary cooling in the cooling chamber 1333, it is then introduced into the cooling chamber 1311 through the air outlet channel 1332, ultimately cooling the glass surface. This allows the air to be pre-cooled before entering the cooling chamber 1311, thereby improving cooling efficiency. Furthermore, the uniform cooling through the cooling chamber 1311 ensures the uniformity of air temperature during the glass cooling process. When the cooling gas comes into contact with the glass, its own temperature rises and it is then transported back to the receiving chamber 121 for storage through the second channel 123, allowing the airflow to be circulated and reused, thereby improving the energy-saving effect of the glass heat treatment mechanism 100.

[0037] Furthermore, in some embodiments, the cooling assembly 130 further includes a cooling medium contained within the cooling chamber 1333. The cooling medium can be a liquid (such as water or an ethylene glycol solution) or a solid (such as ice or a phase change material). The cooling medium is used to absorb heat from the gas as it enters and exits the cooling chamber 1333 through the inlet channel 1331 and the outlet channel 1332, thereby lowering the gas temperature and improving the cooling effect. Specifically, when air enters the cooling chamber 1333 through the inlet channel 1331, the air comes into full contact with the cooling medium, and heat is rapidly transferred to the cooling medium, causing the air temperature to drop. Subsequently, the cooled air is introduced into the cooling chamber 1311 through the outlet channel 1332 to cool the glass surface, thereby not only improving cooling efficiency but also ensuring temperature uniformity during the cooling process.

[0038] In some embodiments, see Figures 1 to 5 As shown, the glass heat treatment mechanism 100 includes two cooling air grids 131 arranged sequentially in the left-right direction. The two cooling chambers 1311 of the cooling air grids 131 are interconnected in the left-right direction, and each of the two cooling chambers 1311 is connected to the receiving cavity 121 through a second channel 123. Specifically, in order to further improve cooling efficiency and uniformity, each cooling air grid 131 defines a cooling chamber 1311, and the two cooling chambers 1311 are interconnected in the left-right direction, thereby forming a continuous cooling area. The cooling chamber 1311 of each cooling air grid 131 is connected to the receiving cavity 121 of the storage component 120 through the second channel 123. After the glass completes the heating step and undergoes preliminary cooling through the first cooling air grid 131, the glass can continue to be conveyed in the left-right direction to the second cooling air grid 131 for further cooling treatment, thereby improving the tempering effect of the glass. Furthermore, since the two cooling chambers 1311 are interconnected, smooth airflow can be ensured during the cooling process, avoiding uneven cooling caused by poor airflow. Meanwhile, continuous cooling zones provide a more uniform cooling process for the glass, reducing the risk of glass breakage due to localized stress concentration and further improving the quality and strength of the glass.

[0039] In some embodiments, during the cooling and tempering stage after the glass has completed the heating stage, excessively low or uneven cooling air temperatures may cause uneven stress distribution within the glass, thereby increasing the risk of spontaneous breakage. See also Figures 1 to 5As shown, to prevent spontaneous glass breakage, in this embodiment of the invention, the glass heat treatment mechanism 100 further includes a pre-cooling component 140, which is used to initially cool the heated glass. The gas temperature in the pre-cooling step is between the gas temperatures in the heating and cooling steps. The pre-cooling component 140 includes a pre-cooling air grid 141 and a pre-cooling fan 142, wherein the pre-cooling air grid 141 has a pre-cooling chamber 1411 for cooling the glass inside. The storage component 120 also includes a fourth channel 125, which connects the pre-cooling chamber 1411 and the receiving chamber 121, allowing air to circulate between them. The pre-cooling fan 142 is installed between the fourth channel 125 and the pre-cooling air grid 141, and is used to introduce air from the receiving chamber 121 and send it into the pre-cooling chamber 1411 through the pre-cooling fan 142.

[0040] Specifically, the pre-cooling assembly 140 is positioned between the heating assembly 110 and the cooling assembly 130 in a left-right direction. This pre-cooling step, occurring between the heating and cooling steps, allows the glass to undergo a gradual cooling process after exiting the heating furnace 111, thereby reducing internal stress changes and improving the glass's tempering strength. In actual operation, after the glass enters the heating assembly 110 and completes the heating step, it needs to undergo preliminary cooling in the pre-cooling chamber 1411 of the pre-cooling assembly 140 before the cooling step. Since the receiving chamber 121 stores gas, and the gas temperature is lower than that of the gas in the heating furnace 111, the air from the receiving chamber 121 can be introduced into the pre-cooling chamber 1411 via the pre-cooling fan 142 and the fourth channel 125. This lower-temperature gas provides preliminary cooling to the glass, allowing it to gradually adapt to the low-temperature environment and preventing thermal stress caused by sudden temperature changes, which could lead to glass breakage upon impact.

[0041] Furthermore, in one embodiment, see [reference] Figures 1 to 6 As shown, the precooling chamber 1411 has a third opening 1412 formed on the outer wall of the precooling air grille 141. The precooling fan 142 is located at the third opening 1412, thereby ensuring that the air in the receiving cavity 121 can smoothly enter the precooling chamber 1411. In addition, the storage component 120 also includes a fifth channel 126, which also connects the precooling chamber 1411 and the receiving cavity 121, and is arranged opposite to the third opening 1412 in the front-back direction. This allows gas to enter or leave the precooling chamber 1411 from different directions, forming a more uniform airflow distribution.

[0042] Specifically, when the precooling fan 142 operates, the gas in the receiving cavity 121, under the negative pressure generated by the precooling fan 142, enters the precooling cavity 1411 through the fourth channel 125, thereby precooling the glass in the precooling cavity 1411. Because the surface temperature of the glass is high, the temperature of the precooling gas increases after it comes into contact with the glass. After precooling, this portion of the precooling gas returns to the receiving cavity 121 through the fifth channel 126, thus forming a complete airflow cycle. This not only ensures the uniformity of airflow during the precooling process but also allows the precooling gas to return to the receiving cavity 121 for use in subsequent cooling steps, achieving heat recycling throughout the entire tempering system. This reduces the demand for fresh external air by the glass heat treatment mechanism 100 and lowers overall energy consumption.

[0043] In some embodiments, see Figure 7 and Figure 8 As shown, the storage unit 120 also defines a sixth channel 127, which is used to exhaust hot air in the heating chamber 1111 and introduce it into the receiving chamber 121. The sixth channel 127 connects the heating chamber 1111 and the receiving chamber 121, and is respectively arranged on both sides of the heating furnace 111 with the heating fan 112. That is, the position of the sixth channel 127 connecting the heating furnace 111 and the arrangement position of the heating fan 112 are opposite to each other, thus forming an airflow circulation system together.

[0044] Specifically, after the glass heating process is complete, the remaining high-temperature air in the heating chamber 1111 is not discharged into the external environment, but is guided through the sixth channel 127 to the receiving cavity 121 of the storage unit 120 for storage. This recovered high-temperature heated air can be reused in subsequent glass heating processes, thereby reducing the amount of gas that the heating fan 112 needs to heat and lowering the overall energy consumption of the glass heat treatment mechanism 100. In actual operation, the heating fan 112 draws air from the receiving cavity 121 and inputs it into the heating chamber 1111 through the first opening 1112 to heat the glass. After the glass heating step is completed, the sixth channel 127 guides the hot air in the heating chamber 1111 to the receiving cavity 121. Since this portion of air has an initial temperature, storing it in the containment cavity 121 can serve as a pre-cooling air source to pre-cool the glass during the pre-cooling step, or as a heating gas during initial equipment startup or restart of a production batch, thereby reducing the workload of the heating fan 112, increasing the temperature of the heating cavity 1111, and shortening the preparation time, thus improving the glass processing efficiency and reducing the energy consumption of the glass heat treatment mechanism 100.

[0045] In some embodiments, the glass heat treatment mechanism 100 further includes a movable member. Movable members are provided inside both the first channel 122 and the second channel 123. The movable members can move relative to the storage member 120, thereby controlling the communication state between the receiving cavity 121 and the heating cavity 1111 and between the receiving cavity 121 and the cooling cavity 1311, that is, controlling the opening and closing of the first channel 122 and the second channel 123.

[0046] Specifically, the movable component is used to block the communication between the receiving cavity 121 and the heating cavity 1111 and the cooling cavity 1311, respectively. During the heating stage, as the glass enters the heating furnace 111 for heating, the movable component can adjust its position to ensure that the first channel 122 is in the open state, thereby allowing the pre-cooled gas in the receiving cavity 121 to enter the heating cavity 1111, reducing the energy consumption of the heating fan 112. At the same time, the movable component on the second channel 123 will remain in the closed state, thereby preventing the gas in the receiving cavity 121 from flowing into the cooling cavity 1311 and causing gas loss from the receiving cavity 121.

[0047] When the glass completes the heating stage and is ready to enter the cooling stage, the position of the movable component will change accordingly. At this time, the movable component on the first channel 122 will close to cut off the connection between the receiving cavity 121 and the heating cavity 1111, while the movable component on the second channel 123 will open, allowing the cooled air to flow back into the receiving cavity 121 for storage through the second channel 123. This not only helps maintain the cooling effect of the cooling fan 132, but also stores warm gas for subsequent glass heating, improving energy efficiency. In other embodiments, in addition to the movable components in the first channel 122 and the second channel 123, the air inlet channel 1331 and the air outlet channel 1332 of the cooling component 133, as well as the third channel 124, the fourth channel 125, the fifth channel 126, and the sixth channel 127, are also equipped with movable components. The opening and closing of each channel is controlled by the movable components to adjust the gas flow of the glass heat treatment mechanism 100 and improve the glass tempering effect.

[0048] A second aspect of the present invention provides a glass tempering furnace, see below. Figures 1 to 8 As shown, the glass tempering furnace includes a control mechanism and the glass heat treatment mechanism 100 described in any of the above embodiments. The control mechanism is electrically connected to the storage unit 120 and is used to control the opening and closing of channels on the storage unit 120, such as the opening and closing of the first channel 122 and the second channel 123. In some embodiments, the storage unit 120 further includes a third channel 124, a fourth channel 125, a fifth channel 126, and a sixth channel 127. The control mechanism can also control the opening and closing of these channels, that is, control the movement of the moving parts, thereby adjusting the gas flow path of the glass heat treatment mechanism 100 during the glass tempering process.

[0049] Specifically, in one example, a control mechanism is used to control the opening and closing of the first channel 122 and the second channel 123. When the glass enters the heating furnace 111 for heating, since the storage container 120 also stores gas, the heating fan 112 can introduce gas from the receiving cavity 121 through the first channel 122 for heating. Compared to drawing gas from the outside, this reduces the energy consumption of the heating fan 112 in drawing in gas. Furthermore, since the receiving cavity 121 and the heating cavity 1111 are connected, the gas temperature in the receiving cavity 121 is relatively high, which saves heating energy compared to directly drawing in room temperature air from the outside environment for heating. At this time, the first channel 122 is open and the second channel 123 is closed, thereby preventing gas in the storage container 120 from flowing into the cooling cavity 1311.

[0050] After the glass is heated in the furnace 111, it needs to be transported left and right for cooling. When the glass is in the cooling chamber 1311, the first channel 122 is closed and the second channel 123 is open. When the cooling fan 132 draws gas from the external environment into the cooling chamber 1311 to cool the glass, the cooling gas exchanges heat with the glass upon contact, causing the temperature of the cooling gas to rise. At this time, the cooling gas enters the receiving chamber 121 through the second channel 123 for storage. During the subsequent tempering process, the first channel 122 is opened and the second channel 123 is closed. The hot gas stored in the receiving chamber 121 can then be used by the furnace 111, which not only recycles the processing gas but also reduces the energy consumption of heating.

[0051] The glass tempering furnace of this embodiment of the invention can reduce energy consumption and improve glass processing efficiency during the glass tempering process through the glass heat treatment mechanism 100. Furthermore, by controlling the opening and closing of the first channel 122 and the second channel 123 through the control mechanism, the gas path of the glass heat treatment mechanism 100 can be adjusted during the corresponding processing steps of the glass, further improving glass processing efficiency.

[0052] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
