[0035] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0036] First embodiment

[0037] Please refer to Figure 1 The embodiment of the present invention provides a glass annealing production line 10 for annealing plate glass 500. It can avoid turbulence of internal air, ensure the stability of the internal temperature field, improve the annealing effect, and facilitate the realization of precision annealing.

[0038] The glass annealing production line 10 includes an annealing furnace shell 100, a conveying roller 200, a temperature control device 300 and a conveying device 400. The conveying roller 200 and the temperature control device 300 are both installed in the annealing furnace shell 100. The conveying roller 200 is used to convey the plate glass 500 into the annealing furnace shell 100. The temperature control device 300 is used to control the temperature in the annealing furnace shell 100 to achieve annealing of the plate glass 500. The conveying roller 200 and the temperature control device 300 work together to achieve continuous annealing of multiple plate glasses 500 and improve the annealing efficiency. In the actual annealing process, due to various reasons such as poor temperature control or high impurity content in the plate glass 500, the plate glass 500 located on the conveying roller 200 in the annealing furnace may explode, generating a large amount of glass fragments and falling downward. In this embodiment, the conveying device 400 is installed in the annealing furnace shell 100 and is arranged below the conveying roller 200. The glass fragments fall onto the conveying device 400 under the action of gravity. The conveying device 400 is used 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, thereby preventing the glass fragments from accumulating in the annealing furnace shell 100 and affecting the annealing effect.

[0039] In this embodiment, the annealing kiln shell 100 is applied to the glass annealing production line 10, which is used to anneal the plate glass 500, but is not limited to this. In other embodiments, the annealing kiln shell 100 can also be used to anneal other materials, and the application scenario of the annealing kiln shell 100 is not specifically limited.

[0040] Please refer to Figure 2 The annealing furnace shell 100 includes a shell 110 and a guide plate 120. The shell 110 is provided with an internal cavity 111 for accommodating a conveyor roller 200. The conveyor roller 200 is arranged in the internal cavity 111. The conveyor roller 200 can deliver the processed plate glass 500 into the shell 110 for annealing. The conveyor roller 200 can also deliver the annealed plate glass 500 out of the shell 110 to facilitate the next process. Specifically, the guide plate 120 is arranged in the internal cavity 111 and connected to the top of the 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 apart along a first direction. The guide holes 121 are extended along a second direction. The second direction is the conveying direction of the conveyor roller 200. The first direction and the second direction form a preset angle. The preset angle ranges from 20 degrees to 90 degrees. The guide holes 121 are used 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.

[0041] In this embodiment, the preset angle is 90 degrees, that is, the first direction is perpendicular to the second direction, so as to further ensure the stability of the internal temperature field and improve the annealing effect. However, it 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.

[0042] It should be noted that, during the annealing process, under the control of the temperature control device 300, the internal temperature of the annealing kiln shell 100 is different in the conveying direction of the conveying roller 200, so that the annealing temperature of the plate glass 500 at different positions in the annealing kiln shell 100 is different, thereby ensuring the annealing effect. Further, since the annealing temperatures at different positions in the annealing kiln shell 100 are different, the air in the annealing kiln shell 100 has a tendency to flow from a low temperature position to a high temperature position, and in this embodiment, since the guide plate 120 connected to the top of the shell 110 is provided with a guide hole 121 extending in the second direction, the air in the annealing kiln 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, the turbulence of the air in the annealing kiln shell 100 can be effectively avoided, which is convenient for realizing the precise control of the annealing temperature, and is also beneficial for energy saving and improving economic benefits.

[0043] Furthermore, there are multiple guide plates 120, and the multiple guide plates 120 are arranged in parallel and spaced apart along the second direction, and the guide holes 121 on the multiple guide plates 120 are arranged in an aligned manner, so that the air at different positions in the annealing kiln shell 100 flows into the guide holes 121 from between two adjacent guide plates 120, and then flows along the guide holes 121 toward the position with higher temperature, thereby ensuring the smoothness and stability of the air flow in 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, and the 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, with a good guide effect, which can effectively avoid the occurrence of turbulence.

[0044] In this embodiment, the spacing between any two adjacent guide holes 121 on the guide plate 120 is the same, and the apertures of the multiple guide holes 121 are the same. Specifically, the spacing between two adjacent guide holes 121 ranges from 100 mm to 500 mm. A reasonable spacing between two adjacent guide holes 121 can ensure that the air in the annealing furnace shell 100 can quickly enter the guide hole 121 close to it in the first direction, ensuring the guide effect. The aperture of the guide hole 121 ranges from 100 mm to 300 mm. A reasonable aperture of the guide hole 121 can reduce the air flow speed as much as possible while ensuring the guide effect, so as to achieve accurate control of the annealing temperature.

[0045] Please refer to Figure 3 The outer shell 110 includes an outer protective layer 112, a heat-insulating layer 113 and an inner lining layer 114. The outer protective layer 112, the heat-insulating layer 113 and the inner lining layer 114 are arranged in sequence from the outside to the inside, the inner cavity 111 is arranged in the inner lining layer 114, the guide plate 120 is connected to the inner lining layer 114, and the heat-insulating layer 113 is used to keep the inner cavity 111 warm to prevent the external environment temperature from affecting the temperature of the inner cavity 111.

[0046] 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 stainless steel 310S. The thermal insulation layer 113 is made of inorganic non-metallic materials. For example, the thermal insulation layer 113 can be made of aluminum silicate ceramic thermal insulation materials (fiber blankets or loose cotton), polycrystalline mullite fiber blanket thermal insulation materials, or zirconium-containing aluminum silicate thermal insulation materials (fiber blankets or loose cotton). 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 minimize the occupied space while ensuring the thermal insulation effect, thereby reducing the volume of the entire shell 110. However, it is not limited to this. 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.

[0047] Please continue to refer to Figure 2 It is worth noting that the conveying device 400 conveys the glass fragments out of the annealing furnace shell 100 by belt transmission, that is, the conveying device 400 is provided with a conveyor belt 410, and the conveyor belt 410 conveys the glass fragments out of the annealing furnace shell 100 during the circular rotation process 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, wherein the conveying section 411 is arranged above the reset section 412 at intervals, and the conveyor belt 410 located in the conveying section 411 can move to the reset section 412, and the conveyor belt 410 located in the reset section 412 can move to the conveying section 411, so as to realize the circular conveying function of the conveyor belt 410.

[0048] In this embodiment, the annealing furnace 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 in the internal cavity 111 and connected to the outer shell 110. The first load-bearing beam 130 is disposed below the conveying section 411. The first load-bearing beam 130 is used 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 glass fragments.

[0049] Furthermore, the base 140 is connected to the bottom of the housing 110, and together with the housing 110, forms a bottom cavity 141. The second load-bearing beam 150 is disposed in the bottom cavity 141 and is connected to the base 140. The second load-bearing beam 150 is disposed below the reset section 412. The second load-bearing beam 150 is used to support the conveyor belt 410 located in the reset section 412 to prevent the conveyor belt 410 from falling downward under the action of gravity, thereby ensuring the stability of the reset of the conveyor belt 410. Specifically, the conveying section 411 and the reset section 412 of the conveyor belt 410 are disposed in the internal cavity 111 and the bottom cavity 141, respectively, and the internal cavity 111 and the bottom cavity 141 are disposed independently of each other.

[0050] Please refer to Figure 4 The first load-bearing beam 130 includes a load-bearing cross beam 131 and a load-bearing longitudinal beam 132. The load-bearing cross beam 131 is arranged perpendicular to the load-bearing longitudinal beam 132 and is fixedly connected to the load-bearing longitudinal beam 132. The load-bearing cross beam 131 and the load-bearing longitudinal beam 132 work together to further enhance the support effect on the conveyor belt 410 and ensure the stability of the movement of the conveyor belt 410. In this embodiment, the specific structure of the second load-bearing beam 150 is the same as that of the first load-bearing beam 130, which will not be repeated here.

[0051] Please refer to Figure 2 and Figure 5 In this embodiment, the annealing furnace shell 100 further includes a mounting beam 160. The mounting beam 160 is disposed in the internal cavity 111 and is connected to the outer shell 110. The mounting beam 160 is disposed below the conveying roller 200. The mounting beam 160 is used to install a temperature sensor or a curtain; wherein the temperature sensor is used to detect the temperature of the internal cavity 111, so as to accurately control the annealing temperature and improve the annealing effect; the curtain is used to block the air to prevent the air inside and outside the outer shell 110 from circulating with each other, so as to prevent the outside air from affecting the temperature of the internal cavity 111.

[0052] 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 shell 110, and the installation door 170 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 shell 110, and the operating door 180 can be opened or closed to facilitate the displacement or correction of 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 take the blocking block 182 out of 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.

[0053] It should be noted that the outer shell 110 of the annealing furnace shell 100 is provided with a reserved hole 115 and a roller operation hole 116. The reserved hole 115 is arranged close to the mounting beam 160 to reserve a position for facilitating the rapid disassembly and assembly of other auxiliary parts. The roller operation hole 116 is used for the installation of the conveyor roller 200 to facilitate the operation and maintenance of the conveyor roller 200.

[0054] The annealing kiln shell 100 provided by the embodiment of the present invention has an outer shell 110 provided with an internal cavity 111 for accommodating the conveying roller 200, a guide plate 120 is provided in the internal cavity 111 and connected to the top of the outer shell 110, and a plurality of guide holes 121 are provided on the guide plate 120, the plurality of guide holes 121 are arranged in parallel and spaced along a first direction, the guide holes 121 are extended along a second direction, the second direction is the conveying direction of the conveying roller 200, and 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 prior art, the annealing kiln shell 100 provided by the present invention adopts the guide plate 120 connected to the outer shell 110 and the guide holes 121 provided on the guide plate 120, so that turbulence of the internal air can be avoided, the internal temperature field can be ensured to be stable, the annealing effect can be improved, and precision annealing can be achieved. The internal air flow of the glass annealing production line 10 is stable, the annealing effect is good, and energy saving is beneficial.

[0055] Second embodiment

[0056] Please refer to Figure 6 and Figure 7 The embodiment of the present invention provides an annealing kiln shell 100 . Compared with the first embodiment, the difference of this embodiment is that the annealing kiln shell 100 further includes an exhaust pipe 190 .

[0057] It should be noted that an exhaust port 117 is opened 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 used 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.

[0058] In this embodiment, the exhaust pipe 190 is connected to the exhaust port 117, and the air in the internal cavity 111 can be discharged to the outside through the exhaust port 117 and the exhaust pipe 190 in sequence. Specifically, the exhaust pipe 190 is provided with an air volume regulating valve 191, which is used to adjust the flow rate of air discharged to the outside, so as to adjust the pressure relief rate and improve the accuracy of temperature control.

[0059] Furthermore, the spacing between two adjacent guide plates 120 ranges from 200 mm to 800 mm. A reasonable spacing between two adjacent guide plates 120 can facilitate 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, and the diameter of the exhaust pipe 190 ranges from 200 mm to 500 mm. A reasonable diameter of the exhaust pipe 190 can adjust the exhaust flow rate within a larger range, further improving the accuracy of temperature control.

[0060] In the present embodiment, there are multiple exhaust ports 117 and multiple exhaust pipes 190, and the multiple exhaust ports 117 are spaced apart 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.

[0061] The beneficial effects of the annealing furnace shell 100 provided by the embodiment of the present invention are the same as those of the first embodiment, and will not be described in detail herein.

[0062] Third embodiment

[0063] Please refer to Figure 8 The embodiment of the present invention provides an annealing furnace shell 100. Compared with the first embodiment, the difference of this embodiment is that the distance between two adjacent guide holes 121 on the guide plate 120 is different.

[0064] It is worth noting that the plate-shaped glass 500 formed by processing is thinner in the middle and thicker on both sides, resulting in a faster heat dissipation rate in the middle of the plate-shaped glass 500 and a slower heat dissipation rate on both sides. After the conveying roller 200 delivers the processed plate-shaped glass 500 into the housing 110, the width direction of the plate-shaped glass 500 is the first direction. In the first direction, since the heat dissipation rate in the middle of the plate-shaped glass 500 is faster and the heat dissipation rate on both sides is slower, the air temperature at the position corresponding to the middle of the plate-shaped glass 500 in the internal cavity 111 is higher, the molecular activity is higher, the air flow rate is faster, and the air flow rate is larger, while the air temperature at the position corresponding to the two sides of the plate-shaped glass 500 is lower, the molecular activity is lower, the air flow rate is slower, and the air flow rate is smaller.

[0065] In this embodiment, the spacing between two adjacent guide holes 121 in the first direction first decreases and then increases, that is, the density of the multiple guide holes 121 in the first direction first increases and then decreases. 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 air with a larger flow rate at the corresponding position in the middle of the plate-shaped glass 500, and the sparser guide holes 121 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 guide effect.

[0066] Furthermore, the aperture of the guide hole 121 increases first 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 guide effect.

[0067] In this embodiment, the spacing between two adjacent guide holes 121 is limited to decrease first and then increase in the first direction, and the diameter of the guide hole 121 is limited to increase first and then decrease in the first direction. However, this is not limited to this. In other embodiments, only the spacing between two adjacent guide holes 121 may be limited to decrease first and then increase in the first direction, or only the diameter of the guide hole 121 may be limited to increase first and then decrease in the first direction.

[0068] The beneficial effects of the annealing furnace shell 100 provided by the embodiment of the present invention are the same as those of the first embodiment, and will not be described in detail herein.

[0069] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
