[0048] The following describes some embodiments of the present disclosure in detail with reference to the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0049] In the production process of float glass and other plate glass, the annealing kiln is an indispensable core device. Its function is to control the thermal stress of the glass, so that the glass has appropriate permanent stress and temporary stress, and ensure the quality of the glass. Annealing is divided into continuous annealing and hood annealing.

[0050] However, the inventors have discovered that during the continuous annealing process, due to the different annealing temperatures at different locations in the annealing furnace, the air in the annealing furnace will form a chimney effect, that is, the air at the lower temperature will flow to the higher temperature. During the air flow process, since the existing annealing furnace has no diversion function, the air is prone to turbulence, resulting in an unstable temperature field inside the annealing furnace, affecting the annealing effect and not conducive to achieving precision annealing.

[0051] Based on this, referring to Figures 1-8 , embodiments of the present disclosure provide an annealing furnace shell 100 and a glass annealing production line 10 configured to anneal plate glass 500. These can prevent internal air turbulence, ensure a stable internal temperature field, improve annealing results, and facilitate precision annealing.

[0052] The glass annealing production line 10 includes an annealing furnace shell 100, a conveyor roller 200, a temperature control device 300, and a conveyor 400. The conveyor roller 200 and the temperature control device 300 are both installed within the annealing furnace shell 100. The conveyor roller 200 is configured to convey plate glass 500 into the annealing furnace shell 100, and the temperature control device 300 is configured to control the temperature within the annealing furnace shell 100 to achieve annealing of the plate glass 500. The conveyor roller 200 and the temperature control device 300 work together to achieve continuous annealing of multiple plate glass 500, thereby improving annealing efficiency. During the actual annealing process, due to various reasons such as poor temperature control or a high impurity content in the plate glass 500, the plate glass 500 located on the conveyor roller 200 in the annealing furnace may explode, generating a large amount of glass fragments that fall downward. In this embodiment, the conveying device 400 is installed in the annealing furnace shell 100 and is arranged below the conveyor roller 200. The glass fragments fall onto the conveying device 400 under the action of gravity. The conveying device 400 is configured to receive the glass fragments and send the glass fragments out of the annealing furnace shell 100 to realize the automatic cleaning and transportation function of the glass fragments, and prevent the glass fragments from accumulating in the annealing furnace shell 100 and affecting the annealing effect.

[0053] In this embodiment, the annealing furnace shell 100 is configured as a glass annealing production line 10. Specifically, it is configured to anneal plate glass 500, but is not limited to this. In other embodiments, the annealing furnace shell 100 can also be configured to anneal other materials. The application scenario of the annealing furnace shell 100 is not specifically limited.

[0054] Referring to Figure 2, the annealing lehr shell 100 includes an outer shell 110 and a guide plate 120. The outer shell 110 is provided with an internal cavity 111 configured to accommodate a conveyor roller 200. The conveyor roller 200 is disposed within the internal cavity 111. The conveyor roller 200 can deliver the processed sheet glass 500 into the outer shell 110 for annealing. The conveyor roller 200 can also deliver the annealed sheet glass 500 out of the outer shell 110 for the next process. Specifically, the guide plate 120 is disposed within the internal cavity 111 and connected to the top of the outer shell 110. The guide plate 120 defines a plurality of guide holes 121. The plurality of guide holes 121 are arranged parallel and spaced along a first direction. The guide holes 121 extend along a second direction, which is the conveying direction of the conveyor roller 200. The first direction and the second direction form a predetermined angle, and the predetermined angle ranges from 20 degrees to 90 degrees. The guide holes 121 are configured to guide the internal air in the internal cavity 111 to limit the flow direction of the internal air, avoid turbulence of the internal air, ensure the stability of the internal temperature field, improve the annealing effect, and facilitate precision annealing.

[0055] In this embodiment, the preset angle is 90 degrees, i.e., the first direction is perpendicular to the second direction, to further ensure the stability of the internal temperature field and improve the annealing effect. However, this is not limited to this. In other embodiments, the preset angle can be 20 degrees or 60 degrees, and the size of the preset angle is not specifically limited.

[0056] It should be noted that during the annealing process, under the control of the temperature control device 300, the internal temperature of the annealing furnace shell 100 varies along the conveying direction of the conveyor roller 200, so that the annealing temperature of the plate glass 500 at different positions within the annealing furnace shell 100 is different, thereby ensuring the annealing effect. Since the annealing temperatures at different positions within the annealing furnace shell 100 are different, the air within the annealing furnace shell 100 tends to flow from a low-temperature position to a high-temperature position. In this embodiment, since the guide plate 120 connected to the top of the outer shell 110 is provided with a guide hole 121 extending along the second direction, the air within the annealing furnace shell 100 will flow along the guide hole 121 in the second direction, and flow from a low-temperature position to a high-temperature position. In this way, turbulence of the air within the annealing furnace shell 100 can be effectively avoided, facilitating the precise control of the annealing temperature, while also contributing to energy conservation and improving economic efficiency.

[0057] Optionally, there are multiple guide plates 120, and the multiple guide plates 120 are arranged in parallel and spaced apart along the second direction. The guide holes 121 on the multiple guide plates 120 are aligned so that air at different positions within the annealing kiln shell 100 flows from between two adjacent guide plates 120 into the guide holes 121, and then flows along the guide holes 121 toward positions with higher temperatures, thereby ensuring the smoothness and stability of the air flow within the annealing kiln shell 100. Specifically, the multiple guide holes 121 on two adjacent guide plates 120 are arranged in a one-to-one correspondence, so that air flowing out of the guide holes 121 of one guide plate 120 can continue to flow along the second direction to the corresponding guide holes 121 of the next guide plate 120, resulting in a good diversion effect and effectively avoiding the occurrence of turbulent flow.

[0058] In this embodiment, the spacing between any two adjacent guide holes 121 on the guide plate 120 is uniform, and the apertures of the multiple guide holes 121 are the same. Specifically, the spacing between any two adjacent guide holes 121 ranges from 100 mm to 500 mm. A reasonable spacing between any two adjacent guide holes 121 ensures that air within the annealing furnace shell 100 can quickly enter the adjacent guide hole 121 in the first direction, thereby ensuring effective diversion. The apertures of the guide holes 121 range from 100 mm to 300 mm. A reasonable aperture of the guide holes 121 can ensure effective diversion while minimizing air flow velocity, thereby facilitating precise control of the annealing temperature.

[0059] 3 , the outer shell 110 includes an outer protective layer 112, an insulating layer 113, and an inner lining layer 114. The outer protective layer 112, the insulating layer 113, and the inner lining layer 114 are arranged sequentially from the outside to the inside. The inner cavity 111 is disposed within the inner lining layer 114. The guide plate 120 is connected to the inner lining layer 114. The insulating layer 113 is configured to insulate the inner cavity 111 to prevent the external ambient temperature from affecting the temperature of the inner cavity 111.

[0060] In this embodiment, the outer protective layer 112 and the inner lining layer 114 are both made of stainless steel. For example, the outer protective layer 112 can be made of Q235B steel, and the inner lining layer 114 can be made of 310S stainless steel. The thermal insulation layer 113 is made of an inorganic non-metallic material. For example, the thermal insulation layer 113 can be made of aluminum silicate ceramic insulation material (fiber blanket or loose wool), polycrystalline mullite fiber blanket insulation material, or zirconium-containing aluminum silicate insulation material (fiber blanket or loose wool). The thickness of the thermal insulation layer 113 ranges from 300 mm to 1000 mm. A reasonable thickness of the thermal insulation layer 113 can ensure thermal insulation while minimizing the space occupied, thereby reducing the volume of the entire housing 110. However, this is not limiting. In other embodiments, the outer protective layer 112 and the inner lining layer 114 can also be made of metal or other alloy materials, and the thermal insulation layer 113 can also be made of other thermal insulation materials. The materials of the outer protective layer 112, the inner lining layer 114, and the thermal insulation layer 113 are not specifically limited.

[0061] Continuing with FIG2 , it is noteworthy that the conveying device 400 conveys the glass fragments out of the annealing furnace shell 100 via a belt drive. Specifically, the conveying device 400 is provided with a conveyor belt 410. The conveyor belt 410 conveys the glass fragments out of the annealing furnace shell 100 during its cyclic rotation to prevent the glass fragments from affecting the annealing effect. Specifically, the conveyor belt 410 is relatively provided with a conveying section 411 and a reset section 412. The conveying section 411 is spaced above the reset section 412. The conveyor belt 410 in the conveying section 411 can move to the reset section 412, and the conveyor belt 410 in the reset section 412 can move to the conveying section 411, thereby achieving the cyclic conveying function of the conveyor belt 410.

[0062] In this embodiment, the annealing lehr shell 100 further includes a first load-bearing beam 130, a base 140, and a second load-bearing beam 150. The first load-bearing beam 130 is disposed within the internal cavity 111 and is connected to the outer shell 110. The first load-bearing beam 130 is disposed below the conveying section 411 and is configured to support the conveyor belt 410 located in the conveying section 411 to prevent the conveyor belt 410 from falling downward under the action of gravity, thereby ensuring the stability of the conveying of the glass fragments.

[0063] Optionally, the base 140 is connected to the bottom of the housing 110 and, together with the housing 110, defines a bottom cavity 141. A second load-bearing beam 150 is disposed within the bottom cavity 141 and is connected to the base 140. The second load-bearing beam 150 is disposed below the reset section 412 and is configured to support the conveyor belt 410 within the reset section 412 to prevent the conveyor belt 410 from falling downward under gravity and to ensure the stability of the reset of the conveyor belt 410. Specifically, the conveyor section 411 and the reset section 412 of the conveyor belt 410 are disposed within the internal cavity 111 and the bottom cavity 141, respectively. The internal cavity 111 and the bottom cavity 141 are disposed independently of each other.

[0064] Referring to Figure 4 , first load-bearing beam 130 includes a load-bearing crossbeam 131 and a load-bearing longitudinal beam 132. Crossbeam 131 is disposed perpendicular to and fixedly connected to longitudinal beam 132. Crossbeam 131 and longitudinal beam 132 work together to further enhance support for conveyor belt 410 and ensure the stability of conveyor belt 410. In this embodiment, the specific structure of second load-bearing beam 150 is identical to that of first load-bearing beam 130 and will not be further described herein.

[0065] 2 and 5 , in this embodiment, the annealing furnace shell 100 further includes a mounting beam 160. The mounting beam 160 is disposed within the internal cavity 111 and is connected to the outer shell 110. The mounting beam 160 is disposed below the conveyor roller 200 and is configured to mount a temperature sensor or a curtain. The temperature sensor is configured to detect the temperature of the internal cavity 111 to facilitate precise control of the annealing temperature and improve the annealing effect. The curtain is configured to block air to prevent air from circulating between the inside and outside of the outer shell 110, thereby preventing outside air from affecting the temperature of the internal cavity 111.

[0066] In this embodiment, the annealing furnace shell 100 also includes an installation door 170, an operating door 180, and a blocking block 182. The installation door 170 is installed on the outer shell 110 and can be opened or closed to facilitate the installation and maintenance of the temperature control device 300. The operating door 180 is installed on the outer shell 110 and can be opened or closed to facilitate operations such as shifting or correcting the plate glass 500 on the conveyor roller 200. The operating door 180 is provided with an observation port 181, and the blocking block 182 is installed in the observation port 181. The user can remove the blocking block 182 from the observation port 181 to observe the movement state of the plate glass 500 and the conveyor roller 200 in the annealing furnace shell 100, which is convenient, fast, and safe.

[0067] It should be noted that the outer shell 110 of the annealing lehr shell 100 is provided with a reserved hole 115 and a roller operation hole 116. The reserved hole 115 is located near the mounting beam 160 to reserve space for quick assembly and disassembly of other auxiliary components. The roller operation hole 116 is configured to accommodate the conveyor roller 200, facilitating its operation and maintenance.

[0068] The annealing furnace shell 100 provided in the embodiment of the present disclosure has an outer shell 110 provided with an internal cavity 111 configured to accommodate a conveyor roller 200. A guide plate 120 is disposed in the internal cavity 111 and connected to the top of the outer shell 110. The guide plate 120 is provided with a plurality of guide holes 121. The plurality of guide holes 121 are arranged in parallel and spaced along a first direction. The guide holes 121 extend along a second direction, which is the conveying direction of the conveyor roller 200. The first direction and the second direction form a preset angle, and the preset angle ranges from 20 degrees to 90 degrees. Compared with the related art, the annealing furnace shell 100 provided in the present disclosure can avoid internal air turbulence due to the use of the guide plate 120 connected to the outer shell 110 and the guide holes 121 provided on the guide plate 120, thereby ensuring a stable internal temperature field, improving the annealing effect, and facilitating precision annealing. This ensures stable air flow within the glass annealing production line 10, good annealing effect, and energy saving.

[0069] 6 and 7 , the annealing furnace shell 100 further includes an exhaust pipe 190 .

[0070] It should be noted that an exhaust port 117 is provided at the top of the outer shell 110. The exhaust port 117 is connected to the internal cavity 111 and is arranged between two adjacent guide plates 120. The exhaust port 117 is configured to discharge the air in the internal cavity 111 to the outside to achieve a pressure relief function. The exhaust port 117 can discharge the air in the annealing kiln shell 100 when the air flows from a low-temperature position to a high-temperature position, so as to avoid the chimney effect of the air in the annealing kiln shell 100, further ensure the stability of the temperature field inside the annealing kiln shell 100, and improve the annealing effect.

[0071] In this embodiment, exhaust pipe 190 is connected to exhaust port 117, and air in internal cavity 111 can be discharged to the outside through exhaust port 117 and exhaust pipe 190 in sequence. Specifically, exhaust pipe 190 is provided with an air flow regulating valve 191, which is configured to adjust the flow rate of air discharged to the outside, thereby adjusting the pressure relief rate and improving the accuracy of temperature control.

[0072] Optionally, the spacing between two adjacent guide plates 120 ranges from 200 mm to 800 mm. A reasonable spacing between two adjacent guide plates 120 facilitates the opening of the exhaust port 117 and the installation of the exhaust pipe 190. The exhaust pipe 190 and the exhaust port 117 have the same diameter, ranging from 200 mm to 500 mm. A reasonable diameter of the exhaust pipe 190 allows for adjustment of the exhaust flow rate over a wide range, further improving the accuracy of temperature control.

[0073] In this embodiment, there are multiple exhaust ports 117 and exhaust pipes 190, and the multiple exhaust ports 117 are arranged at intervals along the first direction. Each exhaust port 117 is connected to an exhaust pipe 190, and each exhaust pipe 190 is provided with a gas volume regulating valve 191. By adjusting the exhaust flow rate of each gas volume regulating valve 191, the internal cavity 111 can be exhausted in a zoned manner, thereby achieving overall precise control of the annealing temperature.

[0074] Referring to FIG. 8 , the distances between two adjacent guide holes 121 on the guide plate 120 are different.

[0075] It is noteworthy that the processed sheet glass 500 is thinner in the middle and thicker on the sides, resulting in a faster heat dissipation rate in the middle of the sheet glass 500 and a slower heat dissipation rate on the sides. After the conveyor rollers 200 deliver the processed sheet glass 500 into the housing 110, the width direction of the sheet glass 500 becomes the first direction. In this first direction, because the heat dissipation rate in the middle of the sheet glass 500 is faster and the heat dissipation rate on the sides is slower, the air temperature in the internal cavity 111 corresponding to the middle of the sheet glass 500 is higher, the molecular activity is higher, the air flow rate is faster, and the air flow rate is larger. However, the air temperature in the locations corresponding to the sides of the sheet glass 500 is lower, the molecular activity is lower, the air flow rate is slower, and the air flow rate is smaller.

[0076] In this embodiment, the spacing between two adjacent guide holes 121 first decreases and then increases in the first direction, that is, the density of the multiple guide holes 121 first increases and then decreases in the first direction. In other words, in the first direction, the guide holes 121 in the middle of the guide plate 120 are denser, and the guide holes 121 on both sides are sparser. In this way, the denser guide holes 121 in the middle of the guide plate 120 can guide the larger flow of air at the corresponding position in the middle of the plate glass 500, and the sparser guide holes 121 on both sides of the guide plate 120 can guide the smaller flow of air at the corresponding positions on both sides of the plate glass 500, so as to ensure the guide effect.

[0077] Optionally, the aperture of the guide hole 121 first increases and then decreases in the first direction, that is, in the first direction, the aperture of the guide hole 121 in the middle of the guide plate 120 is larger, and the aperture of the guide holes 121 on both sides is smaller. In this way, the guide hole 121 with a larger aperture in the middle of the guide plate 120 can guide the air with a larger flow rate at the corresponding position in the middle of the plate-shaped glass 500, and the guide holes 121 with a smaller aperture on both sides of the guide plate 120 can guide the air with a smaller flow rate at the corresponding positions on both sides of the plate-shaped glass 500, so as to ensure the diversion effect.

[0078] In this embodiment, the spacing between two adjacent guide holes 121 is limited to first decreasing and then increasing in the first direction, and the diameter of the guide holes 121 is limited to first increasing and then decreasing in the first direction. However, this is not limiting. In other embodiments, only the spacing between two adjacent guide holes 121 may be limited to first decreasing and then increasing in the first direction, or only the diameter of the guide holes 121 may be limited to first increasing and then decreasing in the first direction.

[0079] The above are merely specific embodiments of the present disclosure and are not intended to limit the present disclosure. Those skilled in the art will readily appreciate that the present disclosure may be modified and varied in various ways. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present disclosure shall be included within the scope of protection of the present disclosure.
