Description

Technical Field

[0001] This application relates to the field of coated glass production technology, and in particular to a drying oven for coated glass. Background Technology

[0002] During the production of coated glass, after the coating layer (such as metal film, oxide film, etc.) is attached to the glass surface, it needs to be dried to ensure that the coating layer is tightly bonded to the glass surface, thereby improving the adhesion, corrosion resistance and service life of the coated glass.

[0003] Currently, existing technologies for drying coated glass mostly employ radiant heating with heating lamps. This type of drying equipment mainly consists of a chamber and heating lamps installed on the top and sides of the chamber. Glass is fed into the chamber manually or via a simple conveyor, and the coating layer on the glass surface is heated and dried by the heat radiation generated by the heating lamps. However, this method cannot efficiently heat and dry the coating on the bottom surface of the glass, thus limiting its practicality. To address these issues, a drying chamber for coated glass is proposed. Utility Model Content

[0004] The purpose of this application is to provide a drying oven for coated glass, which achieves efficient drying of both sides of coated glass through the rational use of resources, thus solving the problems mentioned in the background art.

[0005] The present application provides a drying oven for coated glass, which adopts the following technical solution: a drying oven for coated glass, including a box assembly, a top drying assembly and a bottom drying assembly, wherein the box assembly includes an insulated box body and a reflective heat insulation layer installed on the inner wall of the insulated box body, and the top drying assembly includes two blowers and an electromagnetic heating tube installed on the top of the box assembly.

[0006] The bottom drying assembly includes exhaust fans fixedly connected to both sides of the outer surface of the housing assembly. The input end of each exhaust fan is connected to a transfer chamber, the top end of each transfer chamber is connected to an exhaust pipe, the top of each exhaust pipe is connected to an exhaust hood, the output end of each exhaust fan is connected to an exhaust hood, and an electromagnetic heating coil is installed on the inner wall of each exhaust hood. Multiple rotatable hollow tubes are installed on the inner wall of the housing assembly. The two ends of the multiple hollow tubes are respectively connected to the interior of two exhaust hoods. The interior of each hollow tube has evenly distributed air supply holes, and multiple glass conveying discs are fixedly connected to the outer surface of each hollow tube.

[0007] By adopting the above technical solutions, the insulated box in the cabinet assembly can reduce the loss of internal heat to the outside, and the reflective heat insulation layer can reflect heat to the drying area, improving heat utilization. In the top drying assembly, two blowers can deliver air, which is heated by electromagnetic heating tubes to form a hot airflow that acts on the upper surface of the glass, achieving heating and drying of the upper surface coating layer. In the bottom drying assembly, the exhaust fan collects hot air in the drying chamber through the exhaust hood, exhaust pipe, and transfer chamber. The hot air is heated a second time by the electromagnetic heating coil in the exhaust hood and then introduced into the hollow tube. It is then sprayed upward through evenly distributed air outlets, directly acting on the lower surface of the glass. With the support of the glass conveying disc, the hot air on the lower surface is not blocked, achieving efficient heating of the coating layer on the lower surface of the glass. Through the synergistic effect of the top and bottom, a hot airflow circulation is formed, solving the problem that the existing technology can only efficiently heat the upper surface and the bottom surface has poor drying effect. It achieves simultaneous and uniform drying of both sides of the coated glass, improving drying efficiency and coating quality.

[0008] Preferably, the top of the housing assembly is connected to two air inlet pipes, and the two blowers are respectively installed on the top of the two air inlet pipes.

[0009] By adopting the above technical solution, the air inlet pipe can introduce external air, which is then transported to the top drying component in conjunction with the blower. After being heated by the electromagnetic heating tube, the air forms a hot airflow that acts downward on the upper surface of the glass. This solves the problem of low efficiency in the existing technology that relies solely on thermal radiation to heat the upper surface, and achieves efficient drying of the coating layer on the upper surface of the glass.

[0010] Preferably, both exhaust hoods are located above the glass conveying disc, and temperature sensors are installed on the side of the two exhaust hoods that are close to each other.

[0011] By adopting the above technical solution, the exhaust hood can collect hot air above the glass conveying disc, and the temperature sensor can monitor the temperature near the upper surface of the glass in real time, so as to facilitate timely feedback of temperature information to adjust the heating intensity, avoid abnormal coating quality due to excessively high or low temperature, and solve the problem of uncontrollable temperature in the prior art.

[0012] Preferably, guide components are installed at both the inlet and outlet of the housing assembly. The guide component includes a servo motor fixedly connected to the outer surface of the housing assembly, a guide roller fixedly connected to the output shaft end of the servo motor, and the other end of the guide roller rotatably sleeved in the inner wall of the housing assembly.

[0013] By adopting the above technical solution, the servo motor in the guide assembly can drive the guide roller to rotate, which can drive the glass to move stably inside the box assembly, thus benefiting the subsequent double-sided drying work.

[0014] Preferably, an auxiliary roller is provided above the guide roller, and the two ends of the auxiliary roller are respectively rotatably sleeved in the inner walls on both sides of the housing assembly.

[0015] By adopting the above technical solution, the auxiliary roller and the guide roller work together to limit the glass from the top and bottom, preventing the glass from shifting due to vibration or tilting during the conveying process, further ensuring the stable conveying of the glass in the drying chamber and ensuring that the upper and lower surfaces are heated evenly.

[0016] Preferably, a controller is fixedly connected to the outer surface of the housing assembly, and the electrical components inside the top drying assembly, bottom drying assembly, and guide assembly are all electrically connected to the controller.

[0017] By adopting the above technical solution, the controller can centrally control the operation of the top drying component, the bottom drying component, and the guide component, realizing automated linkage of heating intensity, airflow speed, and guide adjustment, making it more practical.

[0018] Preferably, high-temperature resistant sealing curtains are installed at both the inlet and outlet of the housing assembly.

[0019] By adopting the above technical solution, the high-temperature resistant sealing curtain can reduce the heat loss from the inlet and outlet of the box assembly, enhance the sealing performance of the box, solve the problems of large heat loss and high energy consumption in the existing technology, and improve the heat utilization rate.

[0020] Preferably, an external glass conveying assembly is installed at both the inlet and outlet of the box assembly, and a connecting frame is provided at the bottom of the box assembly, with the bottom ends of the two external glass conveying assemblies being fixedly connected by the connecting frame.

[0021] By adopting the above technical solution, the external glass conveying component, together with the connecting frame, can realize the continuous conveying of glass, replacing manual labor, ensuring that glass can enter and exit the box component in an orderly manner, and improving production continuity.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] This drying oven for coated glass reduces heat loss and improves utilization through an insulated box and reflective heat insulation layer in the box assembly. The top drying assembly, with its air inlet pipe, blower, and electromagnetic heating tube, solves the problem of low heating efficiency on the upper surface. The bottom drying assembly, with its exhaust fan, exhaust hood, electromagnetic heating coil, hollow tube, air outlet, and glass conveying disc, achieves efficient heating of the lower surface, forming an upper and lower convection circulation to achieve synchronous and uniform drying on both sides. It also makes reasonable use of resources and reduces energy consumption. Temperature sensors enable temperature control to avoid abnormal coating quality.

[0031] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0032] Example 1: A drying oven for coated glass, referring to... Figure 1 , Figure 2 and Figure 4 The device includes a housing assembly 1, a top drying assembly 2, and a bottom drying assembly 3. The housing assembly 1 includes an insulated housing 101 and a reflective heat insulation layer 102 installed on the inner wall of the insulated housing 101. The top drying assembly 2 includes two blowers 202 and an electromagnetic heating tube 203 installed on the top of the housing assembly 1. The top of the housing assembly 1 is connected to two air inlet pipes 201. The two blowers 202 are respectively installed on the top of the two air inlet pipes 201. The air inlet pipes 201 can introduce external air, which, together with the blowers 202, delivers the air to the interior of the top drying assembly 2. After being heated by the electromagnetic heating tube 203, the air forms a hot airflow that acts downward on the upper surface of the glass. This solves the problem of low efficiency in the prior art that only relies on thermal radiation to heat the upper surface, and achieves efficient drying of the coating layer on the upper surface of the glass.

[0033] Reference Figure 3 , Figure 4 and Figure 5 The bottom drying assembly 3 includes exhaust fans 301 fixedly connected to both sides of the outer surface of the housing assembly 1. Each exhaust fan 301 has an input end connected to a transfer chamber 302, and each transfer chamber 302 has a top end connected to an exhaust pipe 303. Each exhaust pipe 303 has a top end connected to an exhaust hood 304, and each exhaust fan 301 has an output end connected to an exhaust hood 306. Each exhaust hood 306 has an electromagnetic heating coil 307 installed on its inner wall. The inner wall of the housing assembly 1 has multiple rotatable hollow tubes 308, with both ends of each hollow tube 308 connected to the interior of two exhaust hoods 306. The interior of each hollow tube 308 has evenly distributed air supply holes 309. Multiple glass conveying discs 310 are fixedly connected to the outer surface of each hollow tube 308. Two exhaust hoods 304 are located above the glass conveying discs 310. Temperature sensors 305 are installed on the side of the two exhaust hoods 304 that are close to each other. The exhaust hoods 304 can collect hot air above the glass conveying discs 310. The temperature sensors 305 can monitor the temperature near the upper surface of the glass in real time, so as to facilitate timely feedback of temperature information to adjust the heating intensity and avoid abnormal coating quality due to excessively high or low temperatures. This solves the problem of uncontrollable temperature in the prior art.

[0034] Example 2: A drying oven for coated glass, referring to... Figure 2 , Figure 3 and Figure 4Based on the same concept as Embodiment 1 above, this embodiment proposes that guide components 4 are installed at both the inlet and outlet of the housing assembly 1. The guide component 4 includes a servo motor 401 fixedly connected to the outer surface of the housing assembly 1. A guide roller 402 is fixedly connected to the output shaft end of the servo motor 401. The other end of the guide roller 402 is rotatably sleeved in the inner wall of the housing assembly 1. The servo motor 401 in the guide component 4 can drive the guide roller 402 to rotate, which can drive the glass to move stably inside the housing assembly 1, thereby facilitating the subsequent double-sided drying work. An auxiliary roller 403 is provided above the guide roller 402. The two ends of the auxiliary roller 403 are respectively rotatably sleeved in the inner walls on both sides of the housing assembly 1. The auxiliary roller 403 cooperates with the guide roller 402 to limit the glass from the top and bottom, preventing the glass from shifting due to vibration or tilt during the conveying process, further ensuring the stable conveying of the glass in the drying chamber and ensuring uniform heating of the upper and lower surfaces.

[0035] Reference Figure 1 and Figure 2 A controller 5 is fixedly connected to the outer surface of the housing assembly 1. The electrical components inside the top drying assembly 2, bottom drying assembly 3, and guide assembly 4 are all electrically connected to the controller 5. The controller 5 can centrally control the operation of the top drying assembly 2, bottom drying assembly 3, and guide assembly 4, achieving automated linkage of heating intensity, airflow speed, and guide adjustment, making it more practical. High-temperature resistant sealing curtains 6 are installed at both the inlet and outlet of the housing assembly 1. These curtains reduce heat loss from the inlet and outlet, enhance the sealing of the housing, solve the problems of high heat loss and high energy consumption in existing technologies, and improve heat utilization. External glass conveying assemblies 7 are installed at both the inlet and outlet of the housing assembly 1. A connecting frame 8 is provided below the housing assembly 1. The bottom ends of the two external glass conveying assemblies 7 are fixedly connected through the connecting frame 8. The external glass conveying assemblies 7, in conjunction with the connecting frame 8, can achieve continuous glass conveying, ensuring that glass can enter and exit the housing assembly 1 in an orderly manner, improving production continuity.

[0036] The implementation principle of this application embodiment is as follows: The coated glass to be dried is conveyed to the inlet of the box assembly 1 by the external glass conveying component 7. The servo motor 401 in the guide component 4 drives the guide roller 402 to rotate, and the auxiliary roller 403 accurately guides the glass into the drying chamber. The high-temperature resistant sealing curtain 6 at the inlet can reduce the heat loss from the chamber to the outside. After entering the box assembly 1, the glass is placed on the glass conveying disc 310 and is stably conveyed forward by the rotatable hollow tube 308. The heat-insulating box 101 and the reflective heat insulation layer 102 on the inner wall together reduce the heat loss from the chamber and enhance heat reflection, thereby improving the heat utilization efficiency. In the top drying component 2, the blower 202 introduces external air through the air inlet pipe 201. The air is heated by the electromagnetic heating tube 203 to form a hot airflow, which acts directly downward on the upper surface of the glass to achieve the heating and drying of the coating layer on the upper surface. At the same time, the exhaust fan 301 in the bottom drying component 3 is started, and the exhaust fan draws out the heat from the glass. The hood 304, exhaust pipe 303, and transfer chamber 302 collect hot air above the glass. The hot air is then transported to the exhaust hood 306, heated a second time by the electromagnetic heating coil 307, and then introduced into the hollow tube 308. Finally, it is sprayed upward through the evenly distributed air outlets 309, directly acting on the lower surface of the glass and forming a convection circulation with the hot airflow at the top, achieving simultaneous heating on both sides. During the process, the temperature sensor 305 on the exhaust hood 304 monitors the temperature near the upper surface of the glass in real time and feeds the information back to the controller 5. The controller 5 adjusts the operating parameters of the electromagnetic heating tube 203, electromagnetic heating coil 307, blower 202, and exhaust fan 301 in a coordinated manner to ensure stable drying temperature. The dried glass is discharged through the guide component 4 at the outlet and transported to the next process by the external glass conveying component 7. The high-temperature resistant sealing curtain 6 at the outlet further reduces heat loss, achieving efficient and uniform double-sided drying of the coated glass.
