Description

Technical Field

[0001] This application relates to the field of glass forming technology, and in particular to an air-cooled device and a glass forming apparatus. Background Technology

[0002] Glass forming molds, through their specific cavity structures, cool molten glass at high temperatures, shaping it into finished glass that meets design requirements. During this process, the glass forming mold needs to remain in continuous contact with the high-temperature molten glass and constantly absorb heat.

[0003] In traditional technology, glass forming molds can dissipate heat through heat exchange with the air, thus ensuring the smooth progress of the glass forming process. However, with the increase in glass production capacity, the operating pace of glass forming equipment is constantly accelerating, and the contact frequency and contact time between the glass forming mold and the high-temperature molten glass are significantly extended, resulting in a sharp increase in the heat absorbed by the glass forming mold. Under these circumstances, the heat accumulated in the glass forming mold cannot be released in time, which leads to phenomena such as increased mold sticking and increased volatiles at the interface, affecting the quality of the finished glass. Utility Model Content

[0004] Therefore, it is necessary to provide an air-cooling device and a glass forming apparatus to address the problem that the heat accumulated in the glass forming mold in traditional technology cannot be released in time, which affects the quality of the finished glass.

[0005] The technical solution is as follows:

[0006] One embodiment provides an air-cooled device, comprising:

[0007] The air-cooling head is provided with a first air outlet, a second air outlet and an air-cooling cavity. The first air outlet and the second air outlet are both connected to the air-cooling cavity. The first air outlet is used to face the opening of the discharge pipe, and the second air outlet is used to face the molten glass in the mold.

[0008] An air supply mechanism is connected to the air-cooling cavity.

[0009] The aforementioned air-cooling equipment has an air supply mechanism connected to the air-cooling cavity of the air-cooling head, capable of supplying cold air into the cavity. The cold air in the cavity flows out from the first air outlet and blows towards the outlet of the discharge pipe to initially cool the molten glass flowing out of the outlet. The cold air in the cavity can also flow out from the second air outlet and blow towards the molten glass in the mold to perform secondary cooling on the molten glass discharged from the discharge pipe into the mold, thereby effectively removing some of the heat from the molten glass. Compared with traditional technology, the aforementioned air-cooling equipment can effectively reduce the temperature of the molten glass in the mold, thereby reducing the heat transferred from the molten glass to the mold. This allows the heat accumulated in the mold itself to be released in a timely manner, preventing phenomena such as increased mold sticking and increased volatiles at the interface, thus improving the quality of the finished glass.

[0010] In one embodiment, the air-cooling device further includes a partition member disposed within the air-cooling cavity to divide the air-cooling cavity into a first air-cooling channel and a second air-cooling channel. The air supply mechanism is connected to the first air outlet through the first air-cooling channel, and the air supply mechanism is connected to the second air outlet through the second air-cooling channel.

[0011] In one embodiment, the air supply mechanism includes a first air supply duct and a second air supply duct, wherein the first air supply duct is connected to the first air-cooling channel and the second air supply duct is connected to the second air-cooling channel.

[0012] In one embodiment, the air-cooling head has an air inlet side and an air outlet side arranged opposite to each other along a first direction. One end of the first air supply duct is located on the air inlet side and has a first air outlet. The first air outlet is connected to the first air-cooling channel. One end of the second air supply duct is located on the air inlet side and has a second air outlet. The second air outlet is connected to the second air-cooling channel. Both the first air outlet and the second air outlet are located on the air outlet side.

[0013] In one embodiment, the projection of the center of the first air outlet toward the air outlet side is offset from the first air outlet; or / and

[0014] The projection of the center of the second air outlet toward the air outlet side is offset from the second air outlet.

[0015] In one embodiment, at least two first air outlets are provided, and the at least two first air outlets are spaced apart on the air outlet side; or / and

[0016] The second air outlet is provided in at least two locations, with at least two second air outlets distributed at intervals on the air outlet side.

[0017] In one embodiment, one end of the partition is connected to the air inlet side and located between the first air outlet and the second air outlet, and the other end of the partition is connected to the air outlet side and located between the first air outlet and the second air outlet.

[0018] In one embodiment, the air cooling head has a mounting base for fitting against the bottom wall of the mold.

[0019] In one embodiment, the axis of the first air outlet is set at an angle to the mounting base; or / and,

[0020] The axis of the second air outlet is set at an angle to the mounting base.

[0021] Another embodiment provides a glass forming apparatus, the glass forming apparatus including a discharge pipe, a mold, and an air-cooling device as described in any of the above embodiments, wherein the outlet of the discharge pipe is located at the upper part of the mold.

[0022] In the aforementioned glass forming apparatus, the air supply mechanism is connected to the air-cooling cavity of the air-cooling head and can supply cold air into the air-cooling cavity. The cold air in the air-cooling cavity flows out from the first air outlet and blows towards the outlet of the discharge pipe to initially cool the molten glass flowing out from the outlet of the discharge pipe. The cold air in the air-cooling cavity can also flow out from the second air outlet and blow towards the molten glass in the mold to perform secondary cooling on the molten glass discharged from the discharge pipe into the mold, thereby effectively removing some of the heat from the molten glass. Compared with traditional technology, the aforementioned glass forming apparatus can effectively reduce the temperature of the molten glass in the mold, thereby reducing the heat transferred from the molten glass to the mold, allowing the heat accumulated in the mold itself to be released in a timely manner, avoiding phenomena such as increased mold sticking and increased volatiles at the interface, and improving the quality of the finished glass.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0031] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0032] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0033] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0034] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0036] Please see Figure 1 , Figure 3 and Figure 4 One embodiment of this application provides an air-cooled device, including an air-cooling head 100 and an air supply mechanism 200. The air-cooling head 100 is provided with a first air outlet 110, a second air outlet 120, and an air-cooling cavity 130. The first air outlet 110 and the second air outlet 120 are both connected to the air-cooling cavity 130. The first air outlet 110 is used to face the opening of the discharge pipe 300, and the second air outlet 120 is used to face the molten glass 500 in the mold 400. The air supply mechanism 200 is connected to the air-cooling cavity 130.

[0037] In the aforementioned air-cooling equipment, the air supply mechanism 200 is connected to the air-cooling cavity 130 of the air-cooling head 100 and can supply cold air into the air-cooling cavity 130. The cold air in the air-cooling cavity 130 flows out from the first air outlet 110 and blows towards the outlet of the discharge pipe 300 to initially cool the glass liquid 500 flowing out from the outlet of the discharge pipe 300. The cold air in the air-cooling cavity 130 can also flow out from the second air outlet 120 and blow towards the glass liquid 500 in the mold 400 to perform secondary cooling on the glass liquid 500 discharged from the discharge pipe 300 into the mold 400, thereby effectively removing some of the heat from the glass liquid 500. Compared with traditional technology, the use of the aforementioned air-cooling equipment can effectively reduce the temperature of the glass liquid 500 in the mold 400, thereby reducing the heat transferred from the glass liquid 500 to the mold 400, allowing the heat accumulated in the mold 400 to be released in a timely manner, avoiding phenomena such as increased mold sticking and increased volatiles at the interface, and improving the quality of the finished glass.

[0038] In addition, the cold air flowing out of the first air outlet 110 and blowing towards the outlet pipe 300 can not only provide initial cooling for the molten glass 500, but also disperse the volatiles and dust at the outlet pipe 300 and on the surface of the molten glass 500; similarly to the first air outlet 110, the cold air flowing out of the second air outlet 120 and blowing towards the molten glass 500 inside the mold 400 can not only provide secondary cooling for the molten glass 500, but also disperse the volatiles and dust on the surface of the molten glass 500 inside the mold 400, further improving the quality of the finished glass.

[0039] Furthermore, by setting a first air outlet 110 and a second air outlet 120 on the air cooling head 100, the glass liquid 500 at the outlet of the discharge pipe 300 and the glass liquid 500 in the mold 400 can be cooled by one air cooling head 100, thereby reducing space occupation.

[0040] Furthermore, the distance between the first air outlet 110 and the molten glass 500 is approximately 15mm to 30mm, the distance between the second air outlet 120 and the molten glass 500 is approximately 15mm to 30mm, and the air cooling head 100 does not contact the molten glass 500.

[0041] Optionally, the cold air supplied by the air supply mechanism 200 to the air-cooled cavity 130 can be compressed air, nitrogen, or other inert gas to disperse glass volatiles at the three-phase interface, thereby enhancing the service life of the mold 400 and improving the cleanliness of the glass surface.

[0042] Understandably, the dimensions of the air cooling head 100, the first air outlet 110, and the second air outlet can be appropriately adjusted according to requirements such as the production volume of the molten glass 500 and the specifications of the discharge pipe 300.

[0043] Please see Figure 4 In one embodiment, the air-cooled device further includes a partition 600, which is disposed in the air-cooled cavity 130 to divide the air-cooled cavity 130 into a first air-cooled channel 131 and a second air-cooled channel 132. The air supply mechanism 200 is connected to the first air outlet 110 through the first air-cooled channel 131 and to the second air outlet 120 through the second air-cooled channel 132.

[0044] The partition 600 divides the air-cooled cavity 130 into a first air-cooled channel 131 and a second air-cooled channel 132. The cold air delivered by the air supply mechanism 200 can be sent to the first air outlet 110 through the first air-cooled channel 131 and to the second air outlet 120 through the second air-cooled channel 132. In this way, the cold air flowing to the pipe opening and the cold air flowing to the glass liquid 500 in the mold 400 can be separated in the air-cooled cavity 130, thereby realizing the separate control of the cold air flowing to the pipe opening and the cold air flowing to the glass liquid 500 in the mold 400.

[0045] Furthermore, in some feasible embodiments, the opening and closing of the first air outlet 110 can be controlled by opening or closing the first air-cooling channel 131. Similarly, the opening and closing of the second air outlet 120 can be controlled by opening or closing the second air-cooling channel 132.

[0046] Please see Figures 1 to 4 In one embodiment, the air supply mechanism 200 includes a first air supply duct 210 and a second air supply duct 220. The first air supply duct 210 is connected to the first air-cooling channel 131, and the second air supply duct 220 is connected to the second air-cooling channel 132.

[0047] With this configuration, the first air-cooled channel 131 and the second air-cooled channel 132 can be independently controlled by opening and closing the first air supply duct 210 and the second air supply duct 220, thereby achieving on-demand air supply and reducing the energy consumption of the air supply mechanism 200.

[0048] Furthermore, in some feasible embodiments, the air supply mechanism 200 also includes a first flow control valve and a second flow control valve. The first flow control valve is located in the first air supply duct 210, and the second flow control valve is located in the second air supply duct 220. The first flow control valve enables precise control of the cold air flow rate in the first air supply duct 210, and the second flow control valve enables precise control of the cold air flow rate in the second air supply duct 220. This allows for on-demand air supply to the outlet of the air duct and the molten glass 500 in the mold 400, resulting in low implementation costs.

[0049] Please see Figures 1 to 4In one embodiment, the air-cooling head 100 has an air inlet side 140 and an air outlet side 150 arranged opposite to each other along a first direction. One end of the first air supply duct 210 is located on the air inlet side 140 and has a first air outlet 211. The first air outlet 211 is connected to the first air-cooling channel 131. One end of the second air supply duct 220 is located on the air inlet side 140 and has a second air outlet 221. The second air outlet 221 is connected to the second air-cooling channel 132. The first air outlet 110 and the second air outlet 120 are both located on the air outlet side 150.

[0050] The first air supply duct 210 delivers cold air through the first air outlet 211 to the first air-cooling channel 131, and then through the first air-cooling channel 131 to the first air outlet 110, thereby cooling the molten glass 500 at the opening of the discharge pipe 300; similarly, the second air supply duct 220 delivers cold air through the second air outlet 221 to the second air-cooling channel 132, and then through the second air-cooling channel 132 to the second air outlet 120, thereby cooling the molten glass 500 inside the mold 400.

[0051] Furthermore, the air inlet side 140 and the air outlet side 150 of the air cooling head 100 are arranged opposite to each other, so that the cold air can flow from the air inlet side 140 to the air outlet side 150 from the air cooling cavity 130, avoiding the cold air from turning within the air cooling cavity 130, reducing the flow resistance of the cold air within the air cooling cavity 130, and improving the air delivery effect of the air cooling head 100.

[0052] Please see Figure 1 and Figure 3 In one embodiment, at least two first air outlets 110 are provided, and the at least two first air outlets 110 are distributed at intervals on the air outlet side 150.

[0053] By setting at least two first air outlets 110, the cold air blown towards the outlet of the discharge pipe 300 can evenly and efficiently cover the outlet area of ​​the discharge pipe 300, thereby maximizing the use of cold air to cool the glass melt 500.

[0054] Furthermore, the first air outlet 110 is provided with multiple outlets arranged in parallel on the air outlet side 150 so that the cold air can evenly cover the outlet area of ​​the discharge pipe 300.

[0055] As an embodiment that can be implemented simultaneously with or separately from the above embodiments, at least two second air outlets 120 are provided, with at least two second air outlets 120 distributed at intervals on the air outlet side 150.

[0056] The second air outlet 120 is similar to the first air outlet 110, and will not be described again here.

[0057] Please see Figure 3In one embodiment, the projection of the center of the first air outlet 211 toward the air outlet side 150 is offset from that of the first air outlet 110.

[0058] This configuration avoids the situation where the cold air entering the first air-cooling channel 131 from the first air outlet 211 flows directly out of the first air outlet 110, causing uneven air volume at other first air outlets 110. This improves the uniformity of air volume when cold air flows out from different first air outlets 110, allowing the cold air to evenly and effectively cover the pipe opening area of ​​the discharge pipe 300.

[0059] As an embodiment that can be implemented simultaneously with or separately from the above embodiments, the projection of the center of the second air outlet 221 toward the air outlet side 150 is offset from that of the second air outlet 120.

[0060] The second air outlet 221 is similar to the first air outlet 211, and will not be described again here.

[0061] Further, please refer to Figure 3 The air outlet side 150 is provided with a first windbreak 151 and a second windbreak 152. The projection of the center of the first air outlet 211 toward the air outlet side 150 is located in the first windbreak 151, and the projection of the center of the second air outlet 221 toward the air outlet side 150 is located in the second windbreak 152.

[0062] Please see Figure 4 In one embodiment, one end of the partition 600 is connected to the air inlet side 140 and located between the first air outlet 211 and the second air outlet 221, and the other end of the partition 600 is connected to the air outlet side 150 and located between the first air outlet 110 and the second air outlet 120.

[0063] The partition 600 divides the air-cooled cavity 130 into a first air-cooled channel 131 and a second air-cooled channel 132. One end of the partition 600 is located between the first air outlet 211 and the second air outlet 221, and the other end of the partition 600 is located between the first air outlet 110 and the second air outlet 120, so that the first air outlet 211 is connected to the first air outlet 110 through the first air-cooled channel 131, and the second air outlet 221 is connected to the second air outlet 120 through the second air-cooled channel 132.

[0064] Please see Figure 4 In one embodiment, the partition 600 includes a partition plate disposed within the air-cooling cavity 130, such that a first air-cooling channel 131 is formed on one side of the partition plate and a second air-cooling channel 132 is formed on the other side of the partition plate.

[0065] Please see Figure 1 and Figure 4In one embodiment, the air cooling head 100 has a mounting base 160 for fitting against the bottom wall of the mold 400.

[0066] The mounting surface 160 of the air-cooling head 100 is attached to the bottom wall of the mold 400, so that the air-cooling equipment can be installed on the mold 400. This avoids the deviation of the orientation of the first air outlet 110 and the second air outlet 120 due to the displacement of the air-cooling equipment, and ensures the overall fixed reliability of the air-cooling equipment.

[0067] Further, please refer to Figure 1 and Figure 2 The air-cooling head 100 has a first side and a second side arranged opposite to each other along its width direction. The first side is attached to one side wall of the mold 400. The second side is attached to the other side wall of the mold 400 to prevent the air-cooling equipment from moving.

[0068] Optionally, the air cooling head 100 can be installed on the mold 400 by means of a clamp, or by means of snap-fit, threaded connection, etc., without specific limitations.

[0069] Please see Figure 4 In one embodiment, the axis of the first air outlet 110 is set at an angle to the mounting base 160.

[0070] The air cooling head 100 is installed on the mold 400. Since the discharge pipe 300 is located above the mold 400, the axis of the first air outlet 110 is set to form an angle with the mounting bottom surface 160, so that the orientation of the first air outlet 110 is aligned with the discharge port of the discharge pipe 300.

[0071] As an embodiment that can be implemented simultaneously with or separately from the above embodiments, the axis of the second air outlet 120 is set at an angle to the mounting base 160.

[0072] Since the air cooling head 100 is installed on the bottom wall of the mold cavity 400, by making an angle between the axis of the second air outlet 120 and the mounting bottom surface 160, the orientation of the second air outlet 120 can be aligned with the liquid surface of the glass liquid 500 inside the mold 400. Thus, while air cooling the glass liquid 500, it can also blow away the volatiles and dust on the surface of the glass liquid 500.

[0073] Further, please refer to Figure 1 , Figure 2 and Figure 4 The air outlet side 150 is set at an angle to the bottom wall of the mold 400, so that the axis of the first air outlet 110 and the axis of the second air outlet 120 are both set at an angle to the bottom wall of the mold 400.

[0074] Understandably, for glass melt 500 with different forming thicknesses and forming viscosities, the required specifications can be achieved by adjusting the tilt angle of the air outlet side 150, thereby ensuring uniform cooling and shrinkage of the glass melt 500 and guaranteeing the forming quality of the glass rod.

[0075] As further explained, when manufacturing the air-cooling head 100, an alloy material capable of withstanding high-temperature baking and repeated high- and low-temperature impacts without deformation or cracking must be selected as the base material for the air-cooling head 100. The dimensions of the base material are determined by the specifications of the square bar, and then drilling, assembly, and welding are performed according to the design drawings using bending or splicing welding methods to manufacture the air-cooling head 100. The dimensions of the first air outlet 110 and the second air outlet 120 on the air outlet side 150 should preferably be φ2-φ3. If the diameter is too small, cooling pits will appear on the surface of the molten glass 500; if it is too large, the cold air will be too dispersed and will not be able to reach the outlet of the discharge pipe 300 and the glass in the mold 400. The effect of zoned air cooling of liquid glass 500; the surface on which the air cooling equipment is placed must be flat, and it should be fixed with appropriate clamps to ensure the stability of the entire air cooling equipment during use; the welds involved in the air cooling equipment must be checked for sealing to avoid air leakage, otherwise the desired effect may not be achieved. At the same time, it is necessary to ensure that the area of ​​the first air inlet 211 is larger than the sum of the areas of the first air outlet 110, and that the area of ​​the second air inlet 221 is larger than the sum of the areas of the second air outlet 120, to ensure uniform airflow; the air cooling head 100 device is for cooling the liquid glass 500 near the outlet and should not come into contact with the liquid glass 500, otherwise it may cause bubbles in the liquid glass 500 or overpressure cracking of the device.

[0076] Another embodiment provides a glass forming apparatus, which includes a discharge pipe 300, a mold 400, and an air-cooling device as described above, wherein the outlet of the discharge pipe 300 is located at the upper part of the mold 400.

[0077] In the aforementioned glass forming apparatus, the air supply mechanism 200 is connected to the air cooling chamber 130 of the air cooling head 100 and can supply cold air into the air cooling chamber 130. The cold air in the air cooling chamber 130 flows out from the first air outlet 110 and blows towards the outlet of the discharge pipe 300 to initially cool the glass liquid 500 flowing out from the outlet of the discharge pipe 300. The cold air in the air cooling chamber 130 can also flow out from the second air outlet 120 and blow towards the glass liquid 500 in the mold 400 to perform secondary cooling on the glass liquid 500 discharged from the discharge pipe 300 into the mold 400, thereby effectively removing some of the heat from the glass liquid 500. Compared with traditional technology, the aforementioned glass forming apparatus can effectively reduce the temperature of the glass liquid 500 in the mold 400, thereby reducing the heat transferred from the glass liquid 500 to the mold 400, allowing the heat accumulated in the mold 400 to be released in a timely manner, avoiding phenomena such as increased mold sticking and increased volatiles at the interface, and improving the quality of the finished glass.

[0078] In one embodiment, the glass forming apparatus further includes a traction furnace located at one end of the mold 400. The traction furnace can traction the molten glass 500 in the mold 400 through different types of traction mechanisms (such as roller conveyors, traction wheels, wire drawing machines, etc.), thereby drawing the molten glass 500 into a continuous profile at a preset speed. In addition, the traction furnace can also prevent the molten glass 500 from moving toward the air-cooling equipment, thereby avoiding the problem of air-cooling head 100 contacting the molten glass 500 and causing bubbles to form in the molten glass 500 or overpressure cracking of the air-cooling head 100.

[0079] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0080] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application.
