Description

Technical Field

[0001] This application belongs to the field of drying equipment technology, and more specifically, relates to a drying device for the production of coated glass. Background Technology

[0002] Coated glass, as a type of glass product that combines decorative and functional properties, is widely used in architectural curtain walls, automotive windows, and electronic display panels. Before the coating process, the glass substrate must undergo rigorous cleaning to remove surface dust, oil, water stains, and other impurities. After cleaning, a significant amount of moisture remains on the glass substrate surface. If not thoroughly dried promptly, this residual moisture will not only form watermarks on the glass surface, affecting its appearance, but may also react with the coating materials in subsequent coating processes, leading to defects such as pinholes and peeling of the coating layer. Therefore, drying equipment has become an indispensable key piece of equipment in coated glass production lines.

[0003] In existing technologies, drying equipment for coated glass production typically uses a conveyor mechanism to continuously move glass substrates through the drying zone, and hot air is blown onto the glass surface through drying pipes to achieve moisture evaporation. To prevent dust, particles, and other contaminants in the air from re-adhering to the glass surface during the drying process and causing secondary pollution, the industry generally installs a filtration mechanism in the hot air supply path to filter and purify the air entering the drying pipes. However, after long-term use, the filter screen of the filtration mechanism gradually becomes clogged with impurities in the air, leading to a continuous decrease in air permeability, resulting in reduced drying efficiency and uneven drying of the glass surface. Existing drying equipment lacks effective means to detect the air permeability of the filtration mechanism, making it difficult for operators to monitor the clogging status of the filtration mechanism in real time. Maintenance is usually limited to periodically replacing the filter media, which increases the workload of workers. Utility Model Content

[0004] The purpose of this application is to provide a drying device for the production of coated glass, so as to facilitate timely detection of the need to replace the filter screen and improve the drying effect.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: A drying device for coated glass production is provided, comprising a conveying mechanism, a mounting frame, multiple drying pipes, a hot air supply mechanism, and a filtering mechanism. The conveying mechanism is located on the ground and is used to convey glass to be dried. The mounting frame is mounted on top of the conveying mechanism, with its top spaced apart from the conveying mechanism. An alarm component is provided on the mounting frame. Multiple drying pipes are evenly arranged on the mounting frame along the conveying direction of the conveying mechanism. Each drying pipe has multiple air nozzles, which are evenly arranged along the axial direction of the drying pipe. The hot air supply mechanism is located on the mounting frame, and its output end is connected to each drying pipe to provide hot air to the drying pipes, which is then blown onto the glass to be dried by the air nozzles. The filtering mechanism is located on the mounting frame and is used to filter the air supplied to the drying pipes. The filtering mechanism has a detection component for detecting the air permeability of the filtering mechanism. The detection component is electrically connected to the alarm component. When the detection component detects that the air permeability of the filtering mechanism is lower than a threshold, the alarm component sounds an alarm.

[0006] In one possible implementation, the filtration mechanism includes a filter canister and a filter screen. The filter canister is located on top of the mounting bracket, with an air inlet pipe at one end and an air outlet pipe at the other end. The filter screen is located on the inner wall of the filter canister. Air enters the filter canister through the air inlet pipe, passes through the filter screen, and is discharged through the air outlet pipe.

[0007] In one possible implementation, the filter canister includes a left canister, a right canister, and a filter section. The left canister is cylindrical with one end sealed. A first connecting section is provided at the open end of the left canister, and the air inlet pipe is located at the sealed end of the left canister. The right canister is cylindrical with one end sealed. A second connecting section is provided at the open end of the right canister, and the air outlet pipe is located at the sealed end of the right canister. The filter section is cylindrical with third connecting sections at both ends. The third connecting sections are adapted to both the first and second connecting sections so that both ends of the filter section can be screwed and fixed to the left and right canisters. The filter screen is located on the inner wall of the filter section.

[0008] In one possible implementation, the detection component is disposed on the left tank and is used to detect the air pressure inside the left tank. When the air pressure inside the left tank is greater than a threshold, the alarm component sounds an alarm.

[0009] In one possible implementation, the detection assembly includes a detection tube, a piston, and a push-button switch. The detection tube is disposed on the left tank and communicates with the left tank. The piston is slidably disposed inside the detection tube. The push-button switch is disposed inside the detection tube and outside the piston. The push-button switch is electrically connected to the alarm element. When the push-button switch is pressed, the alarm element starts to sound an alarm.

[0010] In one possible implementation, the top of the detection tube is provided with a cap, the push-button switch is located inside the cap, and the detection tube has an air hole near the cap.

[0011] In one possible implementation, the detection tube is arranged vertically, and a retaining ring is provided at the connection between the detection tube and the filter tank. The inner diameter of the retaining ring is smaller than the diameter of the piston, and a counterweight is provided on the top of the piston so that the piston falls and resets when the filter screen is working normally.

[0012] In one possible implementation, the hot air supply mechanism includes a fan and a heat exchanger, wherein the fan is located on top of the mounting frame; the heat exchanger is located on top of the mounting frame, the output end of the fan is connected to the heat exchanger, and the output end of the heat exchanger is connected to the drying pipe.

[0013] In one possible implementation, the air inlet pipe is connected to the output end of the fan, and the air outlet pipe is connected to the air inlet end of the heat exchanger.

[0014] In one possible implementation, the alarm device is an audible and visual alarm, and the audible and visual alarm, the push-button switch, and the external power supply are combined to form a complete alarm circuit.

[0015] The beneficial effects of the drying device for coated glass production provided in this application are as follows: Compared with the prior art, this application, by setting a detection component on the filter mechanism and electrically connecting the detection component to an alarm element, triggers an alarm when the air permeability is detected to be below a threshold. This design directly addresses the pain points of the prior art. The detection component can monitor the changes in air permeability of the filter mechanism in real time, breaking the traditional blind maintenance mode of "periodic replacement". When the filter screen gradually becomes clogged and the air permeability drops below the threshold, the detection component quickly triggers the alarm element. Operators can promptly know the clogging situation and perform targeted maintenance, eliminating the need to rely on fixed-cycle judgments. Timely maintenance ensures that the filter mechanism always maintains good air permeability, ensuring that the hot air output from the hot air supply mechanism smoothly passes through the filter mechanism and enters the drying tube, avoiding reduced hot air supply or uneven flow rate due to insufficient air permeability, thereby improving drying efficiency and shortening the production cycle.

[0024] The drying apparatus for producing coated glass provided in this application will now be described.

[0025] Please refer to the following: Figures 1 to 3 The drying device for coated glass production includes a conveying mechanism 1, a mounting frame 2, multiple drying pipes 3, a hot air supply mechanism 4, and a filtering mechanism 5. The conveying mechanism 1 is located on the ground and is used to convey the glass to be dried. The mounting frame 2 is located on top of the conveying mechanism 1, with its top spaced apart from the conveying mechanism 1. An alarm element 201 is installed on the mounting frame 2. Multiple drying pipes 3 are evenly arranged on the mounting frame 2 along the conveying direction of the conveying mechanism 1. Each drying pipe 3 is equipped with multiple air nozzles 301, which are positioned along the direction of the drying pipe 3. The air is evenly arranged axially; the hot air supply mechanism 4 is mounted on the mounting frame 2, and the output end of the hot air supply mechanism 4 is connected to each drying pipe 3 to provide hot air to the drying pipe 3 and blow it onto the glass to be dried by the jet nozzle 301; the filter mechanism 5 is mounted on the mounting frame 2 to filter the air supplied to the drying pipe 3. The filter mechanism 5 is equipped with a detection component 501 to detect the air permeability of the filter mechanism 5. The detection component 501 is electrically connected to the alarm component 201. When the detection component 501 detects that the air permeability of the filter mechanism 5 is lower than the threshold, the alarm component 201 will sound an alarm.

[0026] The beneficial effects of the drying apparatus for coated glass production provided in this embodiment are as follows: Compared with the prior art, the filter mechanism 5 of the drying apparatus for coated glass production provided in this embodiment is equipped with a detection component 501, and the detection component 501 is electrically connected to the alarm component 201 to form a complete "detection-alarm" linkage mechanism. The detection component 501 can continuously monitor the change in air permeability of the filter mechanism 5, and when the air permeability drops to a preset threshold, it will immediately trigger the alarm component 201 to start.

[0027] This design allows operators to monitor the working status of the filter mechanism 5 in real time without relying on experience or fixed cycles, enabling targeted maintenance. Timely cleaning or replacement of clogged filter mechanisms 5 ensures good air permeability, allowing hot air from the hot air supply mechanism 4 to smoothly pass through the filter mechanism 5 into the drying pipe 3. Sufficient and smoothly flowing hot air is stably blown onto the glass surface through the evenly distributed air nozzles 301 on the drying pipe 3, ensuring rapid and uniform evaporation of moisture from the glass surface and avoiding incomplete drying in certain areas. "On-demand maintenance" replaces blind, periodic replacement, reducing unnecessary maintenance operations and significantly lowering the labor intensity of workers.

[0028] like Figure 3 As shown, the filtration mechanism 5 includes a filter canister 502 and a filter screen 503. The filter canister 502 is located on the top of the mounting bracket 2. One end of the filter canister 502 is provided with an air inlet pipe 507, and the other end of the filter canister 502 is provided with an air outlet pipe 508. The filter screen 503 is located on the inner wall of the filter canister 502. Air enters the filter canister 502 through the air inlet pipe 507, passes through the filter screen 503, and is discharged through the air outlet pipe 508.

[0029] The filtration mechanism 5 uses a filter canister 502 as its core carrier, along with a clearly defined air inlet pipe 507 and air outlet pipe 508, forming a directional airflow path. After air enters the filter canister 502 through the air inlet pipe 507, it is forced to flow over the filter screen 503, ensuring that all air entering the drying system is filtered, effectively intercepting dust, particles, and other impurities in the air, and preventing unfiltered air from directly entering the drying pipe 3.

[0030] The filter screen 503 is fixed to the inner wall of the filter canister 502. Its filtration area and contact method with the airflow remain constant, making the air filtration effect more uniform and stable, ensuring that the cleanliness of the hot air blown to the glass surface is consistent, and avoiding secondary pollution of the glass surface from the source.

[0031] The filter tank 502 provides a stable installation environment for the detection component 501, enabling the detection component 501 to accurately capture changes in air permeability during the filtration process, avoiding fluctuations in detection data caused by the loose structure of the filter mechanism 5, and improving the accuracy of the detection results.

[0032] In addition, the modular structural design makes the disassembly and cleaning of the filter mechanism 5 more convenient. During later maintenance, there is no need to disassemble the entire equipment extensively, which reduces the difficulty of maintenance, extends the service life of the filter mechanism 5, and ensures the long-term stable operation of the equipment.

[0033] In this embodiment, the filter tank 502 includes a left tank 504, a right tank 505, and a filter section 506. The left tank 504 is cylindrical with one end sealed. A first connecting section 510 is provided at the open end of the left tank 504, and an air inlet pipe 507 is provided at the sealed end of the left tank 504. The right tank 505 is cylindrical with one end sealed. A second connecting section 511 is provided at the open end of the right tank 505, and an air outlet pipe 508 is provided at the sealed end of the right tank 505. The filter section 506 is cylindrical with third connecting sections 512 at both ends. The third connecting sections 512 are adapted to both the first connecting section 510 and the second connecting section 511 so that both ends of the filter section 506 can be screwed and fixed to the left tank 504 and the right tank 505. A filter screen 503 is provided on the inner wall of the filter section 506.

[0034] The filter tank 502 is divided into three independent modules: a left tank 504, a right tank 505, and a filter section 506. These three modules are fixed together by screws, and the filter screen 503 is integrated within the filter section 506. This design allows for maintenance of the filter screen 503 without disassembling the entire filter tank 502. Simply unscrew the screws connecting the filter section 506 to the left and right tanks 505 to remove the filter section 506 for cleaning or replacement. This modular structure significantly simplifies maintenance procedures, reduces interference with other components such as the hot air supply mechanism 4 and the drying pipe 3 during maintenance, and lowers the risk of equipment failure due to improper maintenance.

[0035] As an independent module, filter section 506 can be prepared in advance with spare parts. During maintenance, clogged filter section 506 can be directly replaced without stopping the machine to wait for filter screen 503 to be cleaned or replaced, ensuring continuous operation of the production line and avoiding production interruptions due to equipment maintenance. The screw-on fixing method combines reliable connection and convenient assembly and disassembly. After connection, the sealing performance is good, which can effectively prevent air leakage at the connection or direct airflow without filtration, ensuring that the filtration effect is not affected. At the same time, each tank component can be inspected or replaced individually, avoiding the scrapping of the entire filter tank 502 due to local damage, extending the overall service life of the equipment, and reducing the overall cost of equipment procurement and maintenance.

[0036] In addition, the detection component 501 is installed on the left tank 504 to detect the air pressure inside the left tank 504. When the air pressure inside the left tank 504 is greater than the threshold, the alarm component 201 will sound an alarm.

[0037] A clogged filter directly increases the resistance to airflow through the filter canister 502. Assuming a stable airflow from the hot air supply mechanism 4, the air pressure in the left canister 504 will rise accordingly. Based on this physical principle, a detection component 501 is placed in the left canister 504. By detecting changes in air pressure within the left canister 504, the permeability of the filter mechanism 5 is indirectly determined. This detection logic is direct and reliable.

[0038] The left tank 504, serving as the air inlet of the filter tank 502, is the area most sensitive to changes in air pressure. Installing the detection component 501 here allows for rapid detection of air pressure fluctuations, promptly reflecting the degree of clogging of the filter screen 503 and avoiding detection delays. Compared to complex devices that directly detect air permeability, the principle of air pressure detection is simpler, allowing for a more streamlined structure for the corresponding detection component 501, significantly reducing equipment manufacturing costs.

[0039] In this embodiment, the detection component 501 includes a detection tube 513, a piston 514, and a push-button switch 515. The detection tube 513 is disposed on the left tank 504 and is connected to the left tank 504. The piston 514 is slidably disposed inside the detection tube 513. The push-button switch 515 is disposed inside the detection tube 513 and outside the piston 514. The push-button switch 515 is electrically connected to the alarm component 201. When the push-button switch 515 is pressed, the alarm component 201 starts to sound an alarm.

[0040] The detection tube 513 is connected to the left tank 504 and can directly transmit changes in air pressure inside the left tank 504. When the air pressure inside the left tank 504 increases, the air pressure will push the piston 514 inside the detection tube 513 to slide outward until it touches the button switch 515 to trigger the alarm; after the air pressure returns to normal, the piston 514 resets and the alarm is cleared.

[0041] This mechanically triggered structure does not require complex electronic sensing elements or control systems, has low manufacturing costs, and can adapt to the high temperature and airflow fluctuation environment of the drying equipment. It has strong anti-interference ability, high working stability, and long service life.

[0042] The sliding motion of piston 514 directly responds to changes in air pressure, and the triggering logic of push-button switch 515 is clear and its operation is reliable, avoiding signal drift and malfunctions that may occur with electronic detection components, thus improving the reliability of detection and alarm. The maintenance requirements of the mechanical structure are extremely low, requiring only periodic checks to ensure the smooth sliding of piston 514 and the sensitivity of push-button switch 515, significantly reducing equipment maintenance costs and difficulty.

[0043] As a preferred technical solution, the top of the detection tube 513 is provided with a cap 516, the push button switch 515 is located inside the cap 516, and the detection tube 513 is provided with an air hole 517 near the cap 516.

[0044] The cover 516 effectively prevents external dust and impurities from entering the detection tube 513, avoiding problems such as jamming or poor contact of the piston 514 or push-button switch 515 due to impurities, protecting the internal structure of the detection component 501 and extending its service life. An air vent 517 is provided near the cover 516 in the detection tube 513 to balance the air pressure outside the piston 514. When the piston 514 slides towards the cover 516, external air can be discharged through the air vent 517, preventing the formation of a sealed space that would cause air pressure accumulation and hinder the normal sliding of the piston 514. When the piston 514 returns to its original position, external air can enter through the air vent 517, ensuring a smooth return of the piston 514.

[0045] The combined design of the cap 516 and the vent 517 not only provides sealing protection for the detection tube 513 but also ensures internal air pressure balance, making the sliding motion of the piston 514 smoother and more stable, and avoiding detection errors caused by air pressure interference. The smoothness of the piston 514's sliding directly improves the response sensitivity of the detection component 501 to changes in air pressure, ensuring accurate detection results and timely alarm triggering.

[0046] In addition, the detection tube 513 is arranged vertically, and a retaining ring 518 is provided at the connection between the detection tube 513 and the filter tank 502. The inner diameter of the retaining ring 518 is smaller than the diameter of the piston 514. A counterweight is provided on the top of the piston 514 so that the piston 514 falls back to its original position when the filter screen 503 is working normally.

[0047] The detection tube 513 is arranged vertically, and together with the counterweight on the top of the piston 514 and the retaining ring 518 inside the detection tube 513, it forms a complete reset mechanism. The inner diameter of the retaining ring 518 is smaller than the diameter of the piston 514, which can limit the piston 514 and prevent the piston 514 from falling into the left tank 504 due to gravity or airflow impact, thus ensuring the structural integrity of the detection assembly 501.

[0048] The counterweight utilizes gravity to drive the piston 514 to fall and reset stably when the air pressure inside the left tank 504 is normal, ensuring that the push-button switch 515 is in an untriggered state and fundamentally preventing the occurrence of alarms without faults. The vertically arranged detection tube 513 ensures that the sliding direction of the piston 514 is consistent with the direction of gravity. The gravity of the counterweight helps the piston 514 overcome the friction of the inner wall of the detection tube 513, ensuring that the piston 514 resets quickly and smoothly after the air pressure is restored, and preventing the piston 514 from getting stuck in the non-reset position due to friction.

[0049] When the air pressure inside the left tank 504 rises to the threshold, the thrust generated by the air pressure is sufficient to overcome the weight and friction of the counterweight, pushing the piston 514 upward to trigger the alarm. After the air pressure recovers, the counterweight immediately drives the piston 514 to reset, and the alarm is deactivated. This design makes the action logic of the piston 514 clearer and more reliable, improves the working accuracy of the detection component 501, and ensures that the alarm signal is only triggered when the filter mechanism 5 is blocked, providing operators with accurate equipment status feedback.

[0050] like Figure 1 As shown, the hot air supply mechanism 4 includes a fan 401 and a heat exchanger 402. The fan 401 is located on the top of the mounting frame 2. The heat exchanger 402 is located on the top of the mounting frame 2. The output end of the fan 401 is connected to the heat exchanger 402. The output end of the heat exchanger 402 is connected to each drying pipe 3.

[0051] As a power source, the fan 401 can continuously output a stable airflow, providing sufficient power for the supply of hot air and ensuring that the airflow intensity meets the requirements for glass drying, thus avoiding slow moisture evaporation due to insufficient airflow. The heat exchanger 402 is specifically responsible for air heating, which can evenly heat the air output by the fan 401 to the required drying temperature, avoiding localized overheating or underheating, and ensuring that the temperature of the hot air blown onto the glass surface is consistent.

[0052] The coordinated operation of fan 401 and heat exchanger 402 allows operators to flexibly adjust equipment parameters based on actual production conditions such as glass material, thickness, and residual moisture, achieving personalized drying adaptation and improving equipment versatility. Stable airflow intensity and uniform temperature ensure synchronous evaporation of moisture in all areas of the glass, avoiding quality problems caused by uneven drying and improving the stability of the drying effect.

[0053] Meanwhile, the fan 401 and heat exchanger 402, as mature industrial components, have stable performance, long service life, and convenient maintenance, which can ensure the long-term stable operation of the heat supply mechanism 4 and provide basic support for the efficient operation of the entire drying device.

[0054] In this embodiment, the air inlet pipe 507 is connected to the output end of the fan 401, and the air outlet pipe 508 is connected to the air inlet end of the heat exchanger 402. The air inlet pipe 507 of the filter tank 502 is connected to the output end of the fan 401, and the air outlet pipe 508 is connected to the air inlet end of the heat exchanger 402, forming an orderly flow path of fan 401 output → filtration → heating → supply. The design of filtering the air before heating prevents impurities from adhering to the surface of the heat exchanger 402 after heating, preventing a decrease in the heat exchange efficiency of the heat exchanger 402. At the same time, it ensures that the air entering the heat exchanger 402 is clean, and the hot air formed after heating is free of impurities, protecting the glass surface from secondary contamination.

[0055] The filtered air enters the heat exchanger 402 directly for heating, which shortens the air transmission path, reduces the energy loss of hot air during transmission, improves heat exchange efficiency, and ensures that the hot air maintains a sufficient temperature when it reaches the drying tube 3, thus guaranteeing the drying effect.

[0056] Finally, alarm component 201 is selected as an audible and visual alarm. The audible and visual alarm, push-button switch 515 and external power supply are combined to form a complete alarm circuit.

[0057] By transmitting alarm information through the synchronous output of sound and light signals, this system effectively attracts the attention of operators in the complex environment of industrial production workshops, preventing alarm signals from being ignored and improving the efficiency of alarm information transmission. The sound and light alarm, push-button switch 515, and external power supply form a complete alarm circuit. The circuit structure is simple and the connection is reliable. The mechanical triggering method of push-button switch 515 can quickly connect or disconnect the circuit, ensuring timely output of alarm signals without delay.

[0058] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
