Description

Technical Field

[0001] This utility model relates to the field of glass production technology, and in particular to a single-chamber furnace for hot bending of glass. Background Technology

[0002] A single-chamber glass hot bending furnace consists of a furnace body and a trolley. The furnace body has a furnace cavity and a furnace opening. The trolley can close the furnace opening, making the furnace cavity a closed space. A mold is placed on the trolley, and glass is placed on the mold. After the glass is hot bent, it needs to be cooled. After the trolley moves down away from the furnace opening, the glass is cooled by airflow from fans on both sides of the furnace cavity.

[0003] In existing equipment, the airflow pattern within the furnace cavity is as follows: air from both sides impacts the central area of ​​the furnace cavity, then diffuses after collision at the center, forming a circulating airflow that exits through the furnace opening after being blocked by the furnace walls. This results in some areas of the furnace cavity being difficult for the airflow to reach, creating cooling dead zones and leading to insufficient cooling rates in certain parts of the glass. Significant differences in cooling rates across different areas cause uneven stress, making the glass more prone to cracking. Therefore, it is necessary to optimize the fan layout to expand the area that the airflow can reach, thereby reducing the possibility of glass cracking. Utility Model Content

[0004] The technical problem to be solved by this invention is: how to optimize the layout of the fan to expand the range that the airflow can reach, thereby reducing the possibility of glass breakage.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A single-chamber furnace for hot bending of glass, the single-chamber furnace for hot bending of glass comprising: The furnace body has a furnace opening at its bottom. The fan assembly includes a left fan, a right fan, a front fan, and a rear fan. The left fan, the right fan, the front fan, and the rear fan are respectively disposed on the left side wall, the right side wall, the front side wall, and the rear side wall of the furnace body. The positions of the front fan and the rear fan are offset relative to the positions of the left fan and the right fan in the height direction of the furnace body. The fan assembly is used to blow cooling airflow into the furnace body to cool the glass inside the furnace body.

[0006] In some embodiments, the fan assembly is disposed near the upper wall of the furnace body; wherein the air outlet height of the front fan and the rear fan is higher than the air outlet height of the left fan and the right fan.

[0007] In some embodiments, along the height direction of the furnace body, the lower edges of the front fan and the rear fan are flush with the upper edges of the left fan and the right fan.

[0008] In some embodiments, the number of the left fan, the right fan, the front fan, and the rear fan are all two.

[0009] In some embodiments, the two left fans are spaced apart at the same height on the left side wall, the two right fans are spaced apart at the same height on the right side wall, the two front fans are spaced apart at the same height on the front side wall, and the two rear fans are spaced apart at the same height on the rear side wall.

[0010] In some embodiments, the front fan and the rear fan are one-to-one, and each front fan and the corresponding rear fan are symmetrically arranged on the furnace body; the left fan and the right fan are one-to-one, and each left fan and the corresponding right fan are symmetrically arranged on the furnace body.

[0011] In some embodiments, the two left fans are respectively located near the front sidewall and the rear sidewall, and the two left fans are symmetrically arranged on the furnace body; the two front fans are respectively located near the left sidewall and the right sidewall, and the two front fans are symmetrically arranged on the furnace body.

[0012] In some embodiments, the left fan, the right fan, the front fan, and the rear fan all have frequency converters.

[0013] In some embodiments, the glass hot bending single-chamber furnace includes a temperature sensor assembly disposed on the upper wall of the furnace body; the temperature sensor assembly includes an infrared temperature sensor and a thermocouple temperature sensor, the infrared temperature sensor being used to monitor the glass surface temperature, and the thermocouple temperature sensor being used to monitor the internal space temperature of the furnace body.

[0014] In some embodiments, the number of temperature sensor assemblies is two, and the two temperature sensor assemblies are located on the center line of the upper wall in the left-right direction and are symmetrically arranged about the center line of the upper wall in the front-back direction.

[0015] The beneficial effects of this utility model are as follows: By adding fans to the front and rear side walls of the furnace body, with the positions of the front and rear fans offset in the vertical direction relative to the positions of the left and right fans, the newly added front and rear fans, together with the original left and right fans, form a four-way three-dimensional air supply system. This layout greatly optimizes the airflow distribution within the furnace body, enabling the airflow to cover areas that are difficult to reach with traditional dual fans, such as the center and corners of the furnace cavity. This effectively eliminates cooling dead zones, significantly reducing the internal stress of the glass caused by uneven local cooling rates, and greatly reducing the risk of glass deformation or cracking during the cooling process.

[0016] The front and rear fans are staggered in height relative to the left and right fans, creating staggered air outlets. The four-way airflow interacts, collides, and overlaps on different planes within the furnace, easily forming a three-dimensional turbulent flow filling the furnace cavity, rather than a simple planar airflow. This flow pattern breaks the laminar flow state, greatly enhancing the heat exchange efficiency between the airflow and the glass surface, ensuring rapid and uniform heat dissipation, thereby shortening the overall cooling time while maintaining cooling effectiveness.

[0020] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0021] Please refer to Figure 1 and Figure 3 The existing single-chamber glass hot bending furnace includes a furnace body 1 and a trolley 2. The furnace body 1 has a furnace cavity 11 and a furnace opening 12. The trolley 2 can close the furnace opening 12, making the furnace cavity 11 a closed space. A mold 3 is placed on the trolley 2, and glass 4 is placed on the mold 3. A fan 5 is installed on each of the left side wall 1b and the right side wall 1c of the furnace body 1, and a heating wire 6 is installed on the upper wall 1a of the furnace body 1. After hot bending, the glass 4 needs to be cooled; please refer to [reference needed]. Figure 2After the trolley 2 moves away from the furnace opening 12, it relies on the fans 5 on both sides of the furnace cavity 11 to blow air and cool the glass 4. The airflow from the left and right sides impacts the central area of ​​the furnace cavity 11. After colliding in the middle of the furnace cavity 11, the airflow diffuses and forms a circulating airflow that is blocked by the furnace cavity 11 wall and discharged to the furnace opening 12. Some areas of the furnace cavity 11 are difficult for the airflow to reach, forming cooling dead zones, resulting in insufficient cooling rate in some areas of the glass 4.

[0022] Please refer to Figure 4 and Figure 5 The glass hot bending single-chamber furnace provided by this utility model includes a furnace body 1 and a fan assembly. A furnace opening 12 is provided at the bottom of the furnace body 1. The fan assembly includes a left fan 13, a right fan 14, a front fan 15, and a rear fan 16, which are respectively located on the left side wall 1b, right side wall 1c, front side wall 1d, and rear side wall 1e of the furnace body 1. The positions of the front fan 15 and rear fan 16 are offset relative to the positions of the left fan 13 and right fan 14 in the height direction of the furnace body 1. The fan assembly is used to blow cooling airflow into the furnace body 1 to cool the glass 4 inside the furnace body 1.

[0023] As can be seen from the above description, the beneficial effects of this utility model are as follows: By adding fans to the front and rear side walls of furnace body 1, with the positions of the front and rear fans offset in the vertical direction relative to the positions of the left and right fans, the added front and rear fans, together with the original left and right fans, form a four-way three-dimensional air supply system. This layout greatly optimizes the airflow distribution within furnace body 1, enabling the airflow to cover areas that are difficult to reach by traditional dual fans, such as the center and corners of furnace cavity 11. This effectively eliminates cooling dead zones, thereby significantly reducing the internal stress of glass 4 caused by uneven local cooling rates, and greatly reducing the risk of glass 4 deforming or cracking during the cooling process.

[0024] The positions of the front and rear fans are staggered in height relative to the positions of the left and right fans, forming staggered air outlets. The four-way airflow interacts, collides, and superimposes on different planes within the furnace body 1, easily forming a three-dimensional turbulent flow filling the furnace cavity 11, rather than a simple planar airflow. This flow pattern breaks the laminar flow state, greatly enhancing the heat exchange efficiency between the airflow and the glass surface 4, ensuring rapid and uniform heat dissipation, thereby shortening the overall cooling time while maintaining the cooling effect.

[0025] In some embodiments, please refer to Figure 4 and Figure 5 The blower assembly is located near the upper wall 1a of the furnace body 1; wherein the air outlet height of the front blower 15 and the rear blower 16 is higher than the air outlet height of the left blower 13 and the right blower 14.

[0026] As described above, the blower is located at the top of the furnace body 1, creating an airflow gap in the lower part of the furnace cavity 11. The upper jet compresses the hot air, causing it to flow downwards. Cooling airflow is continuously injected, while the hot air flows towards the furnace opening 12 for discharge.

[0027] If necessary, the height of the air outlets of the front fan 15 and the rear fan 16 can be set lower than the height of the air outlets of the left fan 13 and the right fan 14.

[0028] In some embodiments, along the height direction of the furnace body 1, the lower edges of the front fan 15 and the rear fan 16 are flush with the upper edges of the left fan 13 and the right fan 14.

[0029] In some embodiments, there are two left fans 13, two right fans 14, two front fans 15, and two rear fans 16. The two left fans 13 are designated as Left Fan 13a and Left Fan 2 13b, the two right fans 14 are designated as Right Fan 14a and Right Fan 2 14b, the two front fans 15 are designated as Front Fan 15a and Front Fan 2 15b, and the two rear fans 16 are designated as Rear Fan 16a and Rear Fan 2 16b.

[0030] Depending on the needs, the number of left fan 13, right fan 14, front fan 15 and rear fan 16 can also be one each.

[0031] In some embodiments, two left fans 13 are spaced apart and disposed at the same height on the left side wall 1b, two right fans 14 are spaced apart and disposed at the same height on the right side wall 1c, two front fans 15 are spaced apart and disposed at the same height on the front side wall 1d, and two rear fans 16 are spaced apart and disposed at the same height on the rear side wall 1e.

[0032] In some embodiments, the front fan 15 and the rear fan 16 are one-to-one, and each front fan 15 and the corresponding rear fan 16 are symmetrically arranged on the furnace body 1; the left fan 13 and the right fan 14 are one-to-one, and each left fan 13 and the corresponding right fan 14 are symmetrically arranged on the furnace body 1.

[0033] In some embodiments, two left fans 13 are symmetrically arranged on the furnace body 1, and two front fans 15 are symmetrically arranged on the furnace body 1.

[0034] As described above, the front blower 15 and the rear blower 16 are symmetrically arranged on the furnace body 1, the left blower 13 and the right blower 14 are symmetrically arranged on the furnace body 1, the two left blowers 13 are symmetrically arranged on the furnace body 1, and the two front blowers 15 are symmetrically arranged on the furnace body 1, so that the airflow blown by the two left blowers 13 to the front half and the rear half of the furnace cavity 11 is symmetrical under the same parameters, the airflow blown by the two right blowers 14 to the front half and the rear half of the furnace cavity 11 is symmetrical under the same parameters, the airflow blown by the two front blowers 15 to the left half and the right half of the furnace cavity 11 is symmetrical under the same parameters, and the airflow blown by the two rear blowers 16 to the left half and the right half of the furnace cavity 11 is symmetrical under the same parameters.

[0035] The fans can be controlled in groups: left fan 13a and right fan 14a form one group; left fan 2 13b and right fan 2 14b form another group; front fan 15a and rear fan 16a form another group; and front fan 2 15b and rear fan 2 16b form yet another group. The parameters of these fans can be adjusted in groups. By adjusting the parameters of the left fan 13a and right fan 14a combination in stages, the stress in the area in front of glass 4 is controlled; by adjusting the parameters of the left fan 2 13b and right fan 2 14b combination in stages, the stress in the area behind glass 4 is controlled; by adjusting the parameters of the front fan 15a and rear fan 16a combination in stages, the stress in the left area of ​​glass 4 is controlled; and by adjusting the parameters of the front fan 2 15b and rear fan 2 16b in stages, the stress in the right area of ​​glass 4 is controlled.

[0036] The left and right, front and rear fans are arranged symmetrically and face each other, and can be controlled independently in groups. This design allows operators to precisely adjust the wind speed and air volume in different areas according to the actual shape of the glass mold and the hot bending profile, achieving differentiated and fine control of the cooling rate of different areas such as the front / back and left / right of the glass. This makes the control of the annealing cooling curve more precise, the stress distribution of the product more balanced, and the yield higher.

[0037] In some embodiments, the two left fans 13 are respectively located near the front side wall 1d and the rear side wall 1e; the two front fans 15 are respectively located near the left side wall 1b and the right side wall 1c.

[0038] As described above, placing the fans near the corners of the side walls allows the airflow to flow tangentially along the inner wall of the furnace cavity 11, thus creating a unified and stable rotating vortex in the central area of ​​the furnace cavity. This vortex gently and comprehensively sweeps across the surface of the glass 4, avoiding the excessively rapid cooling and thermal stress concentration that might result from strong airflow directly impacting localized areas of the glass 4, thus contributing to a gentler and more uniform overall cooling effect.

[0039] In some embodiments, the left fan 13, right fan 14, front fan 15 and rear fan 16 each have a frequency converter.

[0040] As can be seen from the above description, the fan speed can be steplessly adjusted through a frequency converter, saving energy while meeting different cooling requirements.

[0041] In some embodiments, the glass hot bending single-chamber furnace has a temperature sensor assembly 17 disposed on the upper wall 1a of the furnace body 1.

[0042] As described above, the temperature sensor can monitor the temperature of glass 4 and the temperature inside the furnace cavity 11, and the parameters of the fan can be adjusted based on the temperature data. Placing the temperature sensor on the upper wall 1a of the furnace body 1 can avoid interference with the moving trolley 2 and mold 3 below. On the other hand, since hot air rises, the upper wall 1a is a key location for monitoring the overall temperature field of the furnace cavity 11.

[0043] In some embodiments, the temperature sensor assembly 17 includes an infrared temperature sensor and a thermocouple temperature sensor, wherein the infrared temperature sensor is used to monitor the temperature of the glass surface and the thermocouple temperature sensor is used to monitor the temperature of the space inside the furnace.

[0044] As described above, the combination of infrared temperature sensors and thermocouple temperature sensors enables precise monitoring of the cooling process: the infrared temperature sensor is used for non-contact, precise measurement of the surface temperature of the glass 4 itself, while the thermocouple temperature sensor is used to measure the ambient temperature of the furnace cavity 11. By comparing these two temperature data in real time, the actual cooling rate of the glass can be accurately calculated, providing a closed-loop feedback basis for finely controlling the airflow speed of each fan group, thereby achieving optimal cooling curve control.

[0045] Other types of temperature sensors may also be used as needed.

[0046] In some embodiments, there are two temperature sensor assemblies 17, namely temperature sensor assembly 17a and temperature sensor assembly 17b. The two temperature sensor assemblies 17 are located on the center line of the upper wall 1a of the furnace body 1 in the left-right direction and are symmetrically arranged about the center line of the upper wall 1a of the furnace body 1 in the front-back direction.

[0047] By integrating infrared and thermocouple temperature sensors to obtain temperature sensor components 17, and symmetrically arranging two temperature sensor components 17 on the upper wall 1a of the furnace body, real-time, multi-point monitoring of the glass surface temperature and the ambient temperature inside the furnace is achieved. This system provides closed-loop feedback for the grouped frequency conversion control of the fan, enabling the entire cooling process to be automatically and intelligently adjusted based on real-time temperature data. This not only improves process stability but also reduces reliance on operator experience.

[0048] Please refer to Figure 4 and Figure 5 One embodiment of this utility model is as follows: A single-chamber glass hot bending furnace includes a furnace body 1, a fan assembly, and a trolley 2. The furnace body 1 has a furnace cavity 11 and a furnace opening 12. The trolley 2 can close the furnace opening 12, making the furnace cavity 11 a closed space. A mold 3 is placed on the trolley 2, and glass 4 is placed on the mold 3. The fan assembly includes a left fan 13, a right fan 14, a front fan 15, and a rear fan 16. The left fan 13, right fan 14, front fan 15, and rear fan 16 are respectively located on the left side wall 1b, right side wall 1c, front side wall 1d, and rear side wall 1e of the furnace body 1.

[0049] There are two left fans 13, two right fans 14, two front fans 15, and two rear fans 16. The fan assembly is located near the upper wall 1a of the furnace body. The two left fans 13 are set at the same height on the left side wall 1b, and the two right fans 14 are set at the same height on the right side wall 1c. The left fans 13 and right fans 14 correspond one-to-one and are symmetrically arranged. The two front fans 15 are set at the same height on the front side wall 1d, and the two rear fans 16 are set at the same height on the rear side wall 1e. The front fans 15 and rear fans 16 correspond one-to-one and are symmetrically arranged.

[0050] The two left fans 13 are designated as Left Fan 1 13a and Left Fan 2 13b, the two right fans 14 are designated as Right Fan 1 14a and Right Fan 2 14b, the two front fans 15 are designated as Front Fan 1 15a and Front Fan 2 15b, and the two rear fans 16 are designated as Rear Fan 1 16a and Rear Fan 2 16b. Left Fan 1 13a and Right Fan 1 14a form one group, Left Fan 2 13b and Right Fan 2 14b form another group, Front Fan 1 15a and Rear Fan 1 16a form another group, and Front Fan 2 15b and Rear Fan 2 16b form yet another group. The parameters of these fans are adjusted in these groups.

[0051] The front fan 15 and rear fan 16 are positioned higher than the left fan 13 and right fan 14. In the vertical direction, the lower edges of the front fan 15 and rear fan 16 are flush with the upper edges of the left fan 13 and right fan 14. The two left fans 13 are positioned near the front side wall 1d and the rear side wall 1e, respectively; the two front fans 15 are positioned near the left side wall 1b and the right side wall 1c, respectively. The left fan 13, right fan 14, front fan 15, and rear fan 16 all have frequency converters, allowing for stepless speed adjustment.

[0052] The single-chamber glass hot bending furnace has two temperature sensor assemblies 17, each including an infrared temperature sensor and a thermocouple temperature sensor. The infrared temperature sensor monitors the glass surface temperature, while the thermocouple temperature sensor monitors the internal temperature of the furnace. The two temperature sensor assemblies 17 are designated as temperature sensor assembly one 17a and temperature sensor assembly two 17b. They are located on the centerline of the upper wall 1a of the furnace body 1 along the left-right direction and are symmetrically arranged about the centerline of the upper wall 1a of the furnace body 1 along the front-back direction.

[0053] In summary, the single-chamber glass hot bending furnace provided by this utility model has the following beneficial effects: Significantly improves cooling uniformity and eliminates cooling dead zones: By adding fans to the front and rear side walls of the furnace body, the positions of the front and rear fans are staggered in the vertical direction relative to the positions of the left and right fans. This creates a four-way three-dimensional air supply system together with the original left and right fans. This layout greatly optimizes the airflow distribution within the furnace body, allowing airflow to cover areas that are difficult for traditional dual fans to reach, such as the center and corners of the furnace cavity. This effectively eliminates cooling dead zones, significantly reducing the internal stress caused by uneven local cooling rates in the glass, and greatly reducing the risk of glass deformation or cracking during the cooling process.

[0054] Achieving precise zoning and adjustable control: The left and right, front and rear fans are arranged symmetrically and face each other, and can be controlled independently in groups. This design allows operators to precisely adjust the wind speed and air volume in different areas according to the actual shape of the glass mold and the hot bending profile, achieving differentiated and fine control of the cooling rate of different areas such as the front / back and left / right of the glass. This results in more precise control of the annealing cooling curve, more balanced product stress distribution, and a higher yield.

[0055] Three-dimensional turbulence is created to enhance heat exchange efficiency: By positioning the front and rear fans above the left and right fans, staggered air outlets are formed. The four airflows interact, collide, and overlap on different planes within the furnace, easily forming a three-dimensional turbulent flow filling the furnace cavity, rather than a simple planar airflow. This flow pattern breaks the laminar flow state, greatly enhancing the heat exchange efficiency between the airflow and the glass surface, ensuring rapid and uniform heat dissipation, thereby shortening the overall cooling time while maintaining cooling effectiveness.

[0056] Closed-loop monitoring and feedback enhance automation: By integrating infrared and thermocouple temperature sensors and symmetrically arranging them on the upper wall of the furnace, real-time, multi-point monitoring of the glass surface temperature and the ambient temperature inside the furnace is achieved. This system provides closed-loop feedback for the grouped frequency conversion control of the fans, enabling the entire cooling process to be automatically and intelligently adjusted based on real-time temperature data. This not only improves process stability but also reduces reliance on operator experience.

[0057] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
