Description

Technical Field

[0001] This invention belongs to the field of drying system technology, specifically a glass multi-chamber jet circulation three-dimensional thermal drying system. Background Technology

[0002] During the production of glass products, the surface coatings (such as inks, adhesives, and protective films) often require drying. Traditional glass drying methods mainly include hot air circulation drying, infrared radiation drying, and a combination of both. As glass products become thinner, larger, and more functional, higher demands are placed on the efficiency, uniformity, and yield of the drying process. Traditional drying systems typically force infrared and hot air to operate simultaneously, making it impossible to independently shut off infrared radiation based on glass type, coating characteristics, or drying stage. For coated glass, ultra-thin glass, or organically sensitive coatings, continuous infrared radiation can easily lead to film oxidation, thermal stress cracking, or coating blistering, affecting product yield.

[0003] In addition, infrared heating tubes have high power, and most systems cannot flexibly switch to pure hot air mode. Continuing to turn on infrared heating during preheating, slow cooling, or low moisture content stages will result in energy waste.

[0017] Please see Figures 1-11In this embodiment of the invention, a multi-chamber jet-circulating three-dimensional thermal drying system for glass includes: a dual-speed conveyor frame 1, on one side of which a hot air heating zone and a cooling zone are sequentially arranged; the dual-speed conveyor frame 1 is used to connect the front-end printer and the drying system for connection and conveying; a backlit light box is installed above the dual-speed conveyor frame 1 for visual product inspection, and is equipped with a universal wheel lifting function to achieve side unloading; the conveying adopts a roller surface coated with rubber, and the conveying speed is adjustable; a first heating device 12, a second heating device 13, a third heating device 14, and a fourth heating device 15 are all arranged in the hot air heating zone. The heating devices are arranged sequentially in the hot zone. Each of the first heating device 12, the second heating device 13, the third heating device 14, and the fourth heating device 15 is equipped with a conveyor frame 2. Above the conveyor frame 2, multiple hot air conveying devices 3 are arranged along the length direction. The hot air heating zone is 8m long and uses jet-type hot air heating. Each device can be controlled independently. The cooling system is set in the dual-speed unloading stage 11 in the cooling zone. It is located on the side of the cooling zone away from the hot air heating zone. It is controlled by PLC to realize rapid cooling and conveying to open up the glass spacing and ensure sufficient unloading time.

[0018] In this embodiment, the first heating device 12, the second heating device 13, the third heating device 14, and the fourth heating device 15 have the same structure. Two air compressors 22 are symmetrically arranged below the conveyor frame 2 inside each device. The air compressors 22 have a power of 2.2KW and achieve hot air jet circulation. The circulation method is top blowing, bottom suction, and side return air. Each group is divided into two air chambers with symmetrical left and right circulation to achieve uniform airflow. The cooling system includes a first cooling device 16, a second cooling device 17, and a third cooling device 18, which are respectively arranged in the cooling zone. Each of the first cooling device 16, second cooling device 17, and third cooling device 18 is equipped with a roller frame 21 for rapid glass cooling. Each cooling device group is 2 meters long and uses air cooling. Each group is equipped with two large vortex fans with filters at the top and an exhaust fan at the bottom. A transition conveyor frame 19 is located between the hot air heating zone and the cooling zone.

[0019] In a preferred embodiment, the hot air conveying device 3 further includes: a fixing frame 32, horizontally installed inside the first heating device 12 and located above the infrared heating tube 31, with an air supply pipe 33 fixed to the lower end face of the fixing frame 32, and an air outlet provided on the lower outer wall of the air supply pipe 33; an air box 34, fixed to one side of the lower end face of the fixing frame 32, the air box 34 being sealed and connected to one end of the air supply pipe 33; and a circulating fan 35, disposed outside the first heating device 12, the exhaust port of the circulating fan 35 being connected to one end of a fixed pipe 36, and the other end of the fixed pipe 36 being connected to the other end of the fixed pipe 36. The end is sealed and connected to the air box 34. The air inlet of the circulating fan 35 is equipped with an air filter to ensure air cleanliness. There are two mirror reflectors 37, which are symmetrically arranged. Each mirror reflector 37 is tilted and fixed below the air supply pipe 33 and located on both sides of the air outlet to realize infrared directional radiation and improve the infrared radiation drying effect. Specifically, the circulating fan 35 can deliver external air into the fixed pipe 36. The air enters the air box 34 and flows along the axial direction of the air supply pipe 33. Finally, it is discharged from the air outlet of the air supply pipe 33 and blown towards the infrared heating tube 31 to realize the combined drying of infrared radiation and hot air.

[0020] In this embodiment, the exhaust port of the air guide seat 5 is concentric with the infrared heating tube 31; the baffle plate 52 is rotatably installed inside the fixed pipe 36, with a rotating shaft at one end, which is inserted into the inner wall of the fixed pipe 36. The rotating shaft serves as a fulcrum for rotating the baffle plate 52. A bidirectional servo motor can be installed outside the fixed pipe 36 to drive the baffle plate 52 to rotate in both directions. The bidirectional servo motor can drive the baffle plate 52 to rotate and block the airflow at the end of the bend 51 or inside the fixed pipe 36, so as to control the external air delivered by the circulating fan 35 to enter the air guide seat 5 or the air box 34 accordingly. When infrared radiation and hot air are combined for drying, the baffle plate 52 closes the end of the bend 51 so that air can enter the air box 34 normally. When only the hot air blowing device 4 is used to provide hot air convection drying, the baffle plate 52 closes the inside of the fixed pipe 36, and the air enters the air guide seat 5 through the bend 51.

[0021] In this embodiment, the hot air jetting device 4 includes: two parallel fixed plates 41, with two optical axes 42 horizontally connected between them, one of which is fixed to a guide seat 5; an axial flow tube 6, coaxially slidably sleeved on the outside of the infrared heating tube 31, the length of the axial flow tube 6 being slightly greater than the overall length of the infrared heating tube 31; two connecting plates 43 slidably connected to the optical axes 42; two rings fixed on the axial flow tube 6; and the connecting plates 43 respectively connected and fixed to the rings; when the connecting plates 43 slide along the axial direction of the optical axes 42, the axial flow tube 6 can be slidably sleeved on the outside of the infrared heating tube 31 or separated from the infrared heating tube 31; a transfer pipe 44, one end of which is sealed to the axial flow tube 6; and an exhaust pipe 45, one end of which... The air supply pipe 45 is slidably mounted coaxially within the air supply pipe 33. The other end of the exhaust pipe 45 is fixed with a manifold 46, and the other end of the adapter pipe 44 is connected to the manifold 46. There are multiple spraying components 7 arranged in a row, and each spraying component 7 is equidistantly distributed along the axial direction of the axial flow pipe 6. One end of each spraying component 7 is sealed and connected to the exhaust pipe 45. Specifically, during the hot air convection drying process provided by the hot air spraying device 4, air enters the guide seat 5. At this time, the guide seat 5 is sealed and fitted with the axial flow pipe 6, and the air flows axially along the axial flow pipe 6. The infrared heating tube 31 fully heats the air. The heated hot air enters the adapter pipe 44 and passes through the manifold 46 into the exhaust pipe 45. Finally, the hot air is sprayed onto the glass surface by each spraying component 7.

[0022] With this configuration, the air flows along the axial direction of the axial flow tube 6 and makes full contact with the infrared heating tube 31 along its entire length. Compared with the traditional radial sweep or local flow contact method, the heat exchange path is longer and the air temperature rises more evenly, achieving forced axial through flow and extending the heating path.

[0023] In the drying process for glass of different specifications, such as thin glass or heat-sensitive coated glass, the first heating device 12 and the fourth heating device 15 use hot air blowing device 4 to provide hot air convection drying, while the second heating device 13 and the third heating device 14 use a combination of infrared radiation and hot air drying. The first heating device 12 (preheating section) uses pure hot air convection to make the glass heat up evenly to close to the moisture evaporation temperature, avoiding the direct impact of infrared radiation on the cold glass surface and causing thermal stress cracking. The fourth heating device 15 (slow cooling section) uses pure hot air convection to make the glass cool down steadily, eliminate internal stress, and prevent warping or cracking. The second heating device 13 and the third heating device 14 adopt an infrared + hot air combination. Infrared radiation penetrates the surface and quickly transfers energy to the internal water molecules, while the hot air simultaneously removes the evaporated water vapor, achieving efficient and gentle deep drying. In this embodiment, two axially arranged guide ribs 47 are symmetrically arranged on the outer wall of the exhaust pipe 45, and a support edge is provided on the inner wall of the air supply pipe 33. The guide ribs 47 slide in contact with the support edge to achieve a sliding fit between the exhaust pipe 45 and the air supply pipe 33. One end of the axial flow pipe 6 slides and seals with the exhaust port of the guide seat 5. Two positioning clamps 61 are fixed inside the axial flow pipe 6, and multiple guide vanes 62 are circumferentially distributed between the two positioning clamps 61. The multiple guide vanes 62 are spirally distributed and surround the outside of the infrared heating pipe 31. The spirally distributed guide vanes 62 force the flowing air to rotate and advance along its spiral direction, making the airflow swirling. Compared to simple axial flow, swirling flow can increase the relative velocity between the airflow and the surface of the infrared heating tube 31, improve the convective heat transfer coefficient, and the spiral path makes the actual airflow path in the axial flow tube 6 of the same length longer, resulting in more complete heat exchange. The heat of the infrared heating tube 31 is transferred to the air more efficiently, making the outlet air temperature higher and more uniform.

[0024] In a preferred embodiment, the axial flow tube 6 has multiple sets of through holes 63 corresponding to the blowing assembly 7 on its circumferential sidewall. Each through hole 63 is inclined and consistent with the spiral direction of the guide vane 62. In this way, a portion of the heated air in the axial flow tube 6 can directly enter the corresponding blowing assembly 7 through the through holes 63, ensuring the temperature of the hot air and making the air temperature reaching the glass surface closer to the required heating temperature of the glass, thereby achieving stable heating and drying.

[0025] In this embodiment, a lead screw 48 is rotatably connected between the fixed plates 41, and each of the connecting plates 43 is helically slidably connected to the lead screw 48; thereby, the overall axial adjustment of the hot air blowing device 4 is achieved by rotating the lead screw 48 in both directions.

[0026] The manifold 46 is also connected to a cold air duct 49, which can be used to supply low-temperature air. When the heat provided by the hot air blowing device 4 exceeds the set value, low-temperature air is supplied through the cold air duct 49, which can quickly reduce the mixed air temperature in the manifold 46. Compared with relying on the power correction of the heating tube (large thermal inertia), the response speed of cold air compensation is faster, which is conducive to achieving precise temperature control.

[0027] In this embodiment, the blowing assembly 7 includes: a housing 71, which is coaxially sleeved outside the axial flow tube 6, and an air inlet channel 72 is provided on the circumferential side wall of one end of the housing 71, the air inlet channel 72 being sealed to the exhaust pipe 45; an exhaust channel 73, which is provided on the circumferential side wall of the other end of the housing 71; a permanent magnet rotor 74, which is rotatably installed inside the housing 71, and an air hole is provided between the permanent magnet rotor 74 and the axial flow tube 6; a stator is also provided in the housing 71, which is used to drive the permanent magnet rotor 74 to rotate; and blades 75, which are circumferentially distributed on the inner wall of the permanent magnet rotor 74 and located in the air hole. When the permanent magnet rotor 74 rotates, it can generate axial swirling flow using the blades 75, so that hot air can enter the housing 71 through the air inlet channel 72 and flow axially along the housing 71 and finally be discharged from the exhaust channel 73.

[0028] In this embodiment, each of the housings 71 is rotatably assembled with the axial flow tube 6. A pulse cylinder (not shown in the figure) is connected to the axial flow tube 6. The other end of the pulse cylinder is connected to the housing 71. It can drive the housing 71 to deflect in a small range around the axis of the axial flow tube 6 as the rotation center line during the telescopic operation, thereby realizing dynamic sweeping and blowing to improve the drying uniformity.

[0029] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
