[0028] Please refer to Figure 1 , Figure 1The front cross-sectional schematic diagram of a blast oven suitable for polymerization of organic glass is shown. The blast oven includes a box 10, an air inlet mechanism 20, a heating unit 30, an exhaust mechanism 40 and a transfer mechanism 50. The air inlet mechanism 20 is arranged on the box 10. The heating unit 30 is used to heat the gas entering the box 10 from the air inlet mechanism 20. The transfer mechanism 50 is used to store the plate to be dried. Specifically, in this embodiment, the air inlet mechanism 20 is installed at the top of the box 10. When started, it is used to inhale gas from the outside of the box 10 and send gas into the inside of the box 10. The gas can be, for example, air. The heating unit 30 can be, for example, a heating wire or a heating coil, and is preferably arranged at the air outlet of the air inlet mechanism 20 to improve the heating efficiency of the gas entering the box 10 from the air inlet mechanism 20. The heated gas will fill the entire box 10. In the illustrated structure, the transfer mechanism 50 is a multi-layer frame structure, and each layer of the frame is used to place the plate to be dried.

[0029] Furthermore, the box 10 has a mutually connected accommodation area 11 and an exhaust channel 12, the transfer mechanism 50 is arranged in the accommodation area 11, and the exhaust mechanism 40 is arranged on the box 10 and is connected to the exhaust channel 12. Specifically, in actual implementation, after the user places the plate to be dried on the transfer mechanism 50, the entire transfer mechanism 50 is parked in the accommodation area 11 of the box 10, and after ensuring that the box 10 is relatively sealed, the air inlet mechanism 20 is started, and the gas sent by the air inlet mechanism 20 passes through the heating unit 30 and continuously covers the entire interior of the box 10 to perform a drying process on the plate on the transfer mechanism 50. Among them, part of the gas circulates inside the box 10 to steadily increase the temperature inside the entire box 10 and keep it constant after reaching a certain temperature. The other part of the gas is discharged through the exhaust channel 12 under the action of the exhaust mechanism 40. In this way, the free substances inside the large-format plate are effectively removed.

[0030] Optionally, a heat-insulating material may be laid on the inner wall of the box body 10 so that the temperature of the heated gas can be maintained in the box body 10 for a longer period of time.

[0031] Please refer to Figure 2, the air outlet of the air inlet mechanism 20 is arranged on the box body 10 at a preset angle, the blast oven further comprises a cavity structure 60, the cavity structure 60 is used to divide the accommodating area 11 into a first circulation space 112 and a second circulation space 113, and the transfer mechanism 50 is arranged in the second circulation space 113. Specifically, in the present embodiment, the air inlet mechanism 20 is arranged at a preset angle at the top of the box body 10, so that the air outlet of the air inlet mechanism 20 is inclined to the end surface of the box body 10 and arranged on the box body. The cavity structure 60 is used to divide the accommodating area 11 of the box body 10 into a first circulation space 112 and a second circulation space 113 which are interconnected. Among them, the transfer mechanism 50 is arranged in the second circulation space 113 so as to be movable in or out.

[0032] Furthermore, the cavity structure 60 is also provided with an air inlet (not shown in the figure), and the air inlet mechanism 20 is used to feed gas into the first circulation space 112, so that the gas flows from the first circulation space 112 to the second circulation space 113 through the air inlet (not shown in the figure). Specifically, in the present embodiment, the air inlet mechanism 20 is used to feed gas into the first circulation space 112, and the inclined air outlet enables the gas entering the box to flow in the first circulation space 112 along a single direction. The continuously flowing gas flows to the second circulation space 113 provided with the transfer mechanism 50 after passing through the air inlet (not shown in the figure), and is evenly blown to the plate on the transfer mechanism 50. In addition, after the gas is blown into from one side of the transfer mechanism 50 and blown out from the other side of the transfer mechanism 50, part of the gas will flow back to the first circulation space 112, forming the effect of circulating the heated gas in the box 10, and the other part will enter the exhaust channel 12 and be discharged through the exhaust mechanism 40.

[0033] Please refer to Figure 3The cavity structure 60 includes a first baffle 61 and a second baffle 62. The second baffle 62 is disposed in the box body 10. One end of the first baffle 61 is connected to the end of the second baffle 62, and the other end extends to the air outlet of the air inlet mechanism 20. The first baffle 61 is used to prevent the gas sent into the first circulation space 112 by the air inlet mechanism 20 from blowing toward the transfer mechanism 50, and the air inlet portion (not shown in the figure) is provided on the second baffle 62. Specifically, in one embodiment, the first baffle 61 is disposed in the box body 10 in a horizontal direction, and the second baffle 62 is connected to the end of the first baffle 61 in a vertical direction, and the end of the first baffle 61 away from the second baffle 62 extends toward the air outlet of the air inlet mechanism 20. Among them, the first baffle 61 is used to prevent the gas sent into the first circulation space 112 by the air inlet mechanism 20 from blowing directly toward the transfer mechanism 50, and the air inlet portion (not shown in the figure) is provided on the second baffle 62. In this way, the gas sent into the first circulation space 112 from the inclined air outlet by the air inlet mechanism 20 will flow along the length direction of the first baffle 61, and will flow downward along the height direction of the second baffle 62 when flowing to the corner in the box body 10, and finally the flowing gas will flow from the air inlet part (not shown in the figure) on the second baffle 62 to the transfer mechanism 50 located in the second circulation space 113, thereby realizing lateral air intake.

[0034] Optionally, the volume of the first circulation space 112 is smaller than the volume of the second circulation space 113. Specifically, in this embodiment, the volume of the first circulation space 112 is smaller than the volume of the second circulation space 113. On the one hand, the flow efficiency of the gas delivered into the first circulation space 112 by the air intake mechanism 20 can be improved to ensure that the heated gas can reach the second circulation space 113 faster. On the other hand, the second circulation space 113 with a larger volume is used for parking the transfer mechanism 50.

[0035] Please refer to Figure 4 , the second baffle 62 is also provided with a first filter unit 621, and the first filter unit 621 is used to filter the gas flowing from the first circulation space 112 to the second circulation space 113. Specifically, in this embodiment, the second baffle 62 is also provided with a first filter unit 621 for absorbing solid particle impurities in the heating gas to prevent the gas with impurities from blowing toward the plate, thereby ensuring the cleanliness of the plate. The first filter unit 621 can be made of a porous material, such as a foam or a short fiber interwoven body, and the material can be polyurethane, silicone, polytetrafluoroethylene, etc., which is not limited here.

[0036] Please refer to Figure 5The blast oven further includes a circulating air mechanism 70, which is disposed on the housing 10 near the air outlet of the air inlet mechanism 20, and is used to guide the gas entering the first circulation space 112 from the air inlet mechanism 20 to flow to the second circulation space 113 through the air inlet portion (not shown in the figure), and to flow back to the first circulation space 112 from the second circulation space 113. Specifically, in the present embodiment, the housing 10 is further provided with a circulating air mechanism 70 near the air outlet of the air inlet mechanism 20 and on the housing 10. In actual implementation, the gas fed into the housing 10 by the air inlet mechanism 20 will be guided to flow in the first circulation space 112 along a single direction under the action of the circulating air mechanism 70, so that the gas flows to the second circulation space 113 provided with the transfer mechanism 50 after passing through the air inlet portion (not shown in the figure). Part of the gas flowing in the second circulation space 113 will flow back from the second circulation space 113 to the first circulation space 112 under the action of the circulating air mechanism 70 , and the other part will enter the exhaust channel 12 and be discharged through the exhaust mechanism 40 .

[0037] Optionally, the circulating air mechanism 70 includes a rotating motor 71 and a rotating blade 72, the rotating motor 71 is arranged on the box body 10, the output shaft of the rotating motor 71 passes through the box body 10 and extends into the first circulation space 112, and the rotating blade 72 is arranged at the end of the output shaft. Specifically, in this embodiment, the rotating motor 71 is arranged on the end surface of the box body 10 with the air inlet mechanism 20 spaced apart, and the output shaft of the rotating motor 71 passes through the box body 10 and extends into the first circulation space 112, and the rotating blade 72 is installed at the end of the output shaft. In actual implementation, when the rotating motor 71 is working, the gas sent into the box body 10 by the air inlet mechanism 20 will form a more significant lateral flow under the action of the rotating blade 72, and when the gas flows to the corner of the box body 10, it flows from the air inlet part (not shown in the figure) to the transfer mechanism 50 located in the second circulation space 113, and finally blows to the plate of the transfer mechanism 50. In this way, the plate located in the central area of ​​the box 10 will be continuously blown by the lateral gas, which improves the heat conduction and diffusion efficiency between the plate and the flowing gas, and can quickly and fully remove the free substances inside the plate.

[0038] Optionally, a second filter unit 21 is provided at the air outlet of the air inlet mechanism 20, and the second filter unit 21 is used to filter impurities in the gas entering the box body 10 from the outside of the box body 10. Specifically, in this embodiment, a second filter unit 21 for filtering solid particle impurities in the external gas is provided at the outlet of the air inlet mechanism 20 to prevent the gas with impurities from blowing toward the plate and thus reducing the cleanliness of the plate. The second filter unit 21 can be made of a porous material, such as a foam or a short fiber interwoven body, and the material can be polyurethane, silicone, polytetrafluoroethylene, etc., which is not limited here.

[0039] Optionally, the blast oven further includes a temperature monitoring unit (not shown in the figure) and a control switch (not shown in the figure). The temperature monitoring unit (not shown in the figure) is disposed in the box body 10. The control switch (not shown in the figure) is connected to the air inlet mechanism 20, and is used to shut down the air inlet mechanism 20 when the temperature monitoring unit (not shown in the figure) displays a preset temperature threshold. Specifically, in the present embodiment, at least one temperature monitoring unit (not shown in the figure) connected to the control switch (not shown in the figure) signal is disposed in the box body 10. When the temperature displayed by the temperature monitoring unit (not shown in the figure) reaches the preset temperature threshold, it is proved that the current temperature in the box body 10 is sufficient to completely dry the plate, and the air inlet mechanism 20 does not need to continuously supply gas into the box body 10. At this time, the control switch (not shown in the figure) will automatically shut down the air inlet mechanism 20, effectively saving the use cost of the equipment.

[0040] Optionally, a pulley 51 is provided at the bottom end of the transfer mechanism 50, a guide rail 13 is provided in the box 10, and the pulley 51 is slidably connected to the guide rail 13. Specifically, in this embodiment, a pulley 51 is provided at the bottom end of the transfer mechanism 50, and a guide rail 13 along the width direction of the box 10 is provided on the bottom end face in the box 10, and the pulley 51 is slidably connected to the guide rail 13. In actual implementation, after the user places the plate to be dried on the transfer mechanism 50, the pulley 51 is docked with the guide rail 13 to move the entire transfer mechanism 50 to the inside of the box 10, thereby ensuring that the transfer mechanism 50 does not move during the entire drying process. In addition, this method can ensure that each time the drying process is performed on different plates, the resulting plates obtain nearly the same physical and mechanical properties.

[0041] The present application places the plate to be dried on a transfer mechanism, and sets the transfer mechanism in the accommodating area. The heating unit heats the gas entering the box, and part of the gas circulates inside the box to steadily increase the temperature inside the entire box. The other part of the gas is discharged through the exhaust channel under the action of the exhaust mechanism. The setting of the first circulation space and the second circulation space constrains the flow direction of the incoming air and the hot air, and realizes the lateral air intake to the side of the transfer mechanism. Under the spatial characteristics of the plates being placed horizontally with appropriate intervals in between, the heat can be convectively transferred to the upper and lower surfaces of the plates to achieve relatively sufficient heat exchange, avoid the problem of uneven heat distribution within the width range, improve the heating and heat transfer efficiency of large-format plates, and achieve effective removal of free substances inside.

[0042] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto.
