Description

Technical Field

[0001] This utility model relates to the field of annealing furnace technology, specifically to a modular photovoltaic glass annealing furnace. Background Technology

[0002] A photovoltaic glass annealing furnace is a type of thermal equipment specifically designed for processing photovoltaic glass. Its main function is to reduce or eliminate the stress generated during the manufacturing process of the glass through heat treatment, thereby improving the mechanical strength, light transmittance, and durability of photovoltaic glass, and thus enhancing the overall performance and lifespan of solar panels.

[0003] Patent No. 202121748723.1 discloses a glass annealing furnace. When a hot air blower or a cold air blower heats or cools glass products on a conveying platform, the displacement component shortens the contact distance between the hot air and the cold air and the glass products, and causes the glass products on the conveying platform to be heated or cooled repeatedly, increasing the heating time and frequency of the glass products. This reduces the need for hot air blowers and cold air blowers, thereby reducing resource waste and achieving the effect of saving resources.

[0004] However, in the use of existing glass annealing furnaces, the generated hot and cold air are brought into contact with the glass surface through ventilation ducts. However, the position of the ventilation ducts is fixed, and the distance between the ventilation ducts and the glass cannot be adjusted. This makes it impossible to adapt to the annealing requirements of glass of different thicknesses. At the same time, the waste gas generated during the glass processing in the annealing furnace is directly discharged. However, the discharged waste gas has a high temperature, and the heat in the waste gas cannot be recovered and utilized, resulting in a waste of resources. Therefore, a modular photovoltaic glass annealing furnace is proposed. Utility Model Content

[0005] To address the problems in the background art, this utility model provides a modular photovoltaic glass annealing furnace.

[0006] The technical solution adopted by this utility model to solve its technical problem is a modular photovoltaic glass annealing furnace, including an annealing furnace body. The annealing furnace body is equipped with a conveyor belt for transporting the photovoltaic glass to be processed. The annealing furnace body is equipped with cavity frames A, B, and C, with cavity frame A located to the left of cavity frame B and cavity frame B located to the left of cavity frame C. Hot air blowers are symmetrically bolted to the outside of the annealing furnace body, and connecting pipes A are fixed to the outside of the hot air blowers with screws. One end of the connecting pipe A extends into the cavity frame B, and a corrugated pipe A is inserted into the bottom of cavity frame B. A nozzle B is screwed to one end of the corrugated pipe A. A drive plate A for fixing the nozzle B is screwed to the outside of the nozzle B. A cold air fan is symmetrically screwed to the outside of the annealing furnace body, and a connecting pipe B is screwed to one side of the cold air fan. The end of the connecting pipe B extends into the cavity frame C. A corrugated pipe B is inserted into the bottom of the cavity frame C. A nozzle C is screwed to one end of the corrugated pipe B. A drive plate B for fixing the nozzle C is screwed to the outside of the nozzle C. Adjustment components for moving the nozzle B and nozzle C are symmetrically arranged inside the annealing furnace body.

[0007] By adopting the above technical solution, the photovoltaic glass to be processed is placed on a conveyor belt, which is a metal mesh conveyor belt. The motor drive system drives the conveyor belt to rotate continuously through friction, allowing the photovoltaic glass to enter the main body of the annealing furnace. Then, hot air generated by symmetrically installed hot air fans outside the main body of the annealing furnace is transported to two sets of chamber frames B through connecting pipe A under the control of the controller. Subsequently, the chamber frames B heat both sides of the photovoltaic glass on the conveyor belt through nozzles B on the corrugated pipe A. The heated photovoltaic glass is then transported to one side of the nozzle C. Then, cold air generated by symmetrically installed cold air fans outside the main body of the annealing furnace is transported to the chamber frame C through connecting pipe B. The chamber frame C contacts both sides of the photovoltaic glass through nozzles C on the corrugated pipe B, thereby facilitating the processing of the photovoltaic glass.

[0008] Specifically, an exhaust pipe is inserted into the top of the annealing furnace body to discharge the waste gas inside the annealing furnace body. A filter box is screwed to the end of the exhaust pipe. A branch pipe A is screwed to the outside of the filter box. A plate heat exchanger is screwed to the end of the branch pipe A. A branch pipe B is screwed to the outside of the plate heat exchanger. One end of the branch pipe B extends into the cavity frame A. A spray pipe A is screwed to the bottom of the cavity frame A.

[0009] By adopting the above technical solution, when photovoltaic glass is processed, the waste gas generated in the annealing furnace body is discharged to the outside through the exhaust pipe. Then, the filter screen and activated carbon adsorption screen in the filter box at one end of the exhaust pipe filter and adsorb harmful substances in the waste gas. The treated waste gas is then transported to the plate heat exchanger through branch pipe A. The plate heat exchanger transfers the heat in the waste gas to the cavity frame A through branch pipe A. Then, the nozzle A on the cavity frame A heats the photovoltaic glass entering the annealing furnace body, which facilitates the recovery and utilization of heat in the waste gas, and at the same time facilitates the preheating treatment of photovoltaic glass, thereby improving the processing efficiency of photovoltaic glass.

[0010] Specifically, the adjustment assembly includes a motor, a bidirectional lead screw, and a threaded sleeve. The motor is bolted to the top of the annealing furnace body, and the motor's power output end is keyed to the bidirectional lead screw. The bidirectional lead screw is symmetrically threaded to the outside of the threaded sleeve, and the outside of the threaded sleeve is welded to the A end of the drive plate.

[0011] By adopting the above technical solution, when the positions of nozzles B and C need to be adjusted, the motor inside the annealing furnace body is driven by the controller to rotate the bidirectional lead screw. The two sets of threaded sleeves outside the bidirectional lead screw are limited by the external structure, so that the two sets of threaded sleeves move longitudinally towards each other through the positive and negative threads opened on the outside of the bidirectional lead screw. Then, the two sets of threaded sleeves drive the two sets of drive plates A to move respectively. Then, the drive plates A drive the nozzle B to move. The bellows A on one side of the nozzle B extends, so that the hot air in the cavity frame B can be smoothly ejected from the nozzle B through the bellows A, so that the hot air comes into contact with the photovoltaic glass on the conveyor belt. At the same time, another set of adjustment components in the annealing furnace body adjusts the nozzle C on the drive plate B, so as to facilitate the adjustment of the distance between nozzles B, nozzle C and photovoltaic glass, thereby improving the processing efficiency of photovoltaic glass.

[0012] Specifically, a slider is welded to the outside of the drive plate A, and a slide rail is slidably connected to the inside of the slider.

[0013] By adopting the above technical solution, when the drive plate A moves, the slider welded to the outside of the drive plate A slides outside the slide rail welded inside the annealing furnace body, thereby improving the stability of the longitudinal movement of the drive plate A.

[0014] Specifically, the input terminals of the motor, hot air blower, and cold air blower are all electrically connected to the power supply terminal of an external power source.

[0015] By adopting the above technical solution and connecting to an external power source, the electrical equipment can operate normally.

[0016] The beneficial effects of this utility model are:

[0017] (1) In the modular photovoltaic glass annealing furnace described in this utility model, when the positions of nozzle B and nozzle C need to be adjusted, the motor in the main body of the annealing furnace is driven by the controller to rotate the bidirectional lead screw. The two sets of threaded sleeves outside the bidirectional lead screw are limited by the external structure, so that the two sets of threaded sleeves move longitudinally towards each other through the positive and negative threads opened on the outside of the bidirectional lead screw. Then, the two sets of threaded sleeves drive the two sets of drive plates A to move respectively. Then, the drive plates A drive the nozzle B to move. The bellows A on one side of the nozzle B extends, so that the hot air in the cavity frame B can be smoothly ejected from the nozzle B through the bellows A, so that the hot air comes into contact with the photovoltaic glass on the conveyor belt. At the same time, another set of adjustment components in the main body of the annealing furnace adjusts the nozzle C on the drive plate B, so as to facilitate the adjustment of the distance between the nozzle B, nozzle C and photovoltaic glass, thereby improving the processing efficiency of photovoltaic glass.

[0018] (2) The modular photovoltaic glass annealing furnace of this utility model, when photovoltaic glass is processed, the waste gas generated in the main body of the annealing furnace is discharged to the outside through the exhaust pipe. Then, the filter screen and activated carbon adsorption screen in the filter box at one end of the exhaust pipe filter and adsorb harmful substances in the waste gas. Then, the treated waste gas is transported to the plate heat exchanger through the branch pipe A.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] For the processing of photovoltaic glass, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 As shown, the modular photovoltaic glass annealing furnace of this utility model includes an annealing furnace body 7. A conveyor belt 4 for transporting the photovoltaic glass to be processed is installed inside the annealing furnace body 7. The annealing furnace body 7 is equipped with cavity frames A12, B15, and C17, with cavity frame A12 located to the left of cavity frame B15 and cavity frame B15 located to the left of cavity frame C17. Hot air blowers 9 are symmetrically bolted to the outside of the annealing furnace body 7, and connecting pipes A8 are fixed to the outside of the hot air blowers 9 with screws. One end of the connecting pipe A8 extends into the cavity frame B15, and a corrugated pipe A13 is inserted into the bottom of the cavity frame B15. The end of the corrugated pipe A13... A nozzle B26 is fixed with screws. A drive plate A16, which fixes the nozzle B26, is fixed to the outside of the nozzle B26 with screws. A cool air fan 11 is symmetrically fixed with screws on the outside of the annealing furnace body 7. A connecting pipe B10 is fixed with screws on one side of the cool air fan 11. The end of the connecting pipe B10 extends into the cavity frame C17. A corrugated pipe B18 is inserted into the bottom of the cavity frame C17. A nozzle C20 is fixed with screws at the end of the corrugated pipe B18. A drive plate B19, which fixes the nozzle C20, is fixed to the outside of the nozzle C20 with screws. An adjustment assembly 24, which drives the nozzle B26 and nozzle C20 to move, is symmetrically arranged inside the annealing furnace body 7.

[0026] In operation, the photovoltaic glass to be processed is placed on the conveyor belt 4, which is a metal mesh conveyor belt. The motor 21 drives the system to continuously rotate the conveyor belt 4 through friction, allowing the photovoltaic glass to enter the annealing furnace body 7. Then, the hot air generated by the hot air blowers 9 symmetrically installed outside the annealing furnace body 7 is transported to the two sets of cavity frames B15 through the connecting pipe A8 under the control of the controller. Subsequently, the cavity frames B15 heat both sides of the photovoltaic glass on the conveyor belt 4 through the nozzles B26 on the corrugated pipe A13. The heated photovoltaic glass is then transported to one side of the nozzle C20. Then, the cold air blowers 11 symmetrically installed outside the annealing furnace body 7 transport the generated cold air to the cavity frame C17 through the connecting pipe B10. The cavity frame C17 contacts both sides of the photovoltaic glass through the nozzles C20 on the corrugated pipe B18, thus facilitating the processing of the photovoltaic glass.

[0027] To improve the processing efficiency of photovoltaic glass, for example, such as Figure 1 and Figure 2As shown, this utility model also includes an exhaust pipe 5 inserted into the top of the annealing furnace body 7 to discharge the waste gas inside the annealing furnace body 7. A filter box 1 is screwed to the end of the exhaust pipe 5. A branch pipe A6 is screwed to the outside of the filter box 1. A plate heat exchanger 2 is screwed to the end of the branch pipe A6. A branch pipe B3 is screwed to the outside of the plate heat exchanger 2. One end of the branch pipe B3 extends into the cavity frame A12. A spray pipe A14 is screwed to the bottom of the cavity frame A12.

[0028] During operation, when photovoltaic glass is being processed, the waste gas generated inside the annealing furnace body 7 is discharged to the outside through the exhaust pipe 5. Subsequently, the filter screen and activated carbon adsorption screen in the filter box 1 at one end of the exhaust pipe 5 filter and adsorb harmful substances in the waste gas. The treated waste gas is then transported to the plate heat exchanger 2 through the branch pipe A6. The plate heat exchanger 2 transfers the heat in the waste gas to the cavity frame A12 through the branch pipe A6. Then, the nozzle A14 on the cavity frame A12 heats the photovoltaic glass entering the annealing furnace body 7, thereby facilitating the recovery and utilization of heat in the waste gas and facilitating the preheating treatment of the photovoltaic glass, thus improving the processing efficiency of photovoltaic glass.

[0029] To improve the processing efficiency of photovoltaic glass, for example, such as Figure 3 As shown, the present invention also includes the adjustment component 24, which includes a motor 21, a bidirectional lead screw 22 and a threaded sleeve 23. The motor 21 is bolted to the top of the annealing furnace body 7. The power output end of the motor 21 is keyed to the bidirectional lead screw 22. The threaded sleeve 23 is symmetrically threaded to the outside of the bidirectional lead screw 22, and the outside of the threaded sleeve 23 is welded to the end of the drive plate A16.

[0030] During use, when the positions of nozzles B26 and C20 need to be adjusted, the motor 21 inside the annealing furnace body 7 is driven by the controller to rotate the bidirectional lead screw 22. The two sets of threaded sleeves 23 outside the bidirectional lead screw 22 are limited by the external structure, so that the two sets of threaded sleeves 23 move longitudinally towards each other through the positive and negative threads on the outside of the bidirectional lead screw 22. Then, the two sets of threaded sleeves 23 drive the two sets of drive plates A16 to move respectively. Then, the drive plates A16 drive the nozzle B26 to move. The bellows A13 on one side of the nozzle B26 extends, so that the hot air in the cavity frame B15 can be smoothly ejected from the nozzle B26 through the bellows A13, so that the hot air comes into contact with the photovoltaic glass on the conveyor belt 4. At the same time, another set of adjustment components 24 in the annealing furnace body 7 adjusts the nozzle C20 on the drive plate B19, so as to facilitate the adjustment of the distance between the nozzles B26, C20 and the photovoltaic glass, thereby improving the processing efficiency of the photovoltaic glass.

[0031] To improve the stability of the longitudinal movement of the driver board A16, for example, such as Figure 3As shown, the present invention also includes a slider 25 welded to the outside of the drive plate A16, and a slide rail 27 slidably connected to the inside of the slider 25.

[0032] When in use, as the drive plate A16 moves, the slider 25 welded to the outside of the drive plate A16 slides outside the slide rail 27 welded inside the annealing furnace body 7, thereby improving the stability of the longitudinal movement of the drive plate A16.

[0033] For electrical equipment to function properly, for example, such as Figure 1 , Figure 3 As shown, the present invention also includes that the input terminals of the motor 21, the hot air blower 9, and the cold air blower 11 are all electrically connected to the power supply terminal of an external power source.

[0034] When in use, the electrical equipment works normally by connecting to an external power source.

[0035] In use, the photovoltaic glass to be processed is placed on the conveyor belt 4, which is a metal mesh conveyor belt 4. The motor 21 drives the system to continuously rotate the conveyor belt 4 through friction, so that the photovoltaic glass enters the annealing furnace body 7. Then, the hot air generated by the hot air generated by the hot air blower 9 symmetrically installed outside the annealing furnace body 7 is transported to the two sets of cavity frames B15 through the connecting pipe A8 under the control of the controller. Subsequently, the cavity frame B15 heats both sides of the photovoltaic glass on the conveyor belt 4 through the nozzle B26 on the corrugated pipe A13. The heated photovoltaic glass is then transported to one side of the nozzle C20. Then, the cold air blower 11 symmetrically installed outside the annealing furnace body 7 transports the generated cold air to the cavity frame C17 through the connecting pipe B10. The cavity frame C17 contacts the cold air with both sides of the photovoltaic glass through the nozzle C20 on the corrugated pipe B18, thereby facilitating the processing of the photovoltaic glass.

[0036] When the positions of nozzles B26 and C20 need to be adjusted, the motor 21 inside the annealing furnace body 7 is driven by the controller to rotate the bidirectional lead screw 22. The two sets of threaded sleeves 23 outside the bidirectional lead screw 22 are limited by the external structure, so that the two sets of threaded sleeves 23 move longitudinally towards each other through the positive and negative threads on the outside of the bidirectional lead screw 22. Then, the two sets of threaded sleeves 23 drive the two sets of drive plates A16 to move respectively. Then, the drive plates A16 drive the nozzle B26 to move. The bellows A13 on one side of the nozzle B26 extends, so that the hot air in the cavity frame B15 can be smoothly ejected from the nozzle B26 through the bellows A13, so that the hot air comes into contact with the photovoltaic glass on the conveyor belt 4. At the same time, another set of adjustment components 24 in the annealing furnace body 7 adjusts the nozzle C20 on the drive plate B19, so as to facilitate the adjustment of the distance between the nozzles B26, C20 and the photovoltaic glass, thereby improving the processing efficiency of the photovoltaic glass.

[0037] During photovoltaic glass processing, the waste gas generated inside the annealing furnace body 7 is discharged to the outside through the exhaust pipe 5. Subsequently, the filter screen and activated carbon adsorption screen in the filter box 1 at one end of the exhaust pipe 5 filter and adsorb harmful substances in the waste gas. The treated waste gas is then transported to the plate heat exchanger 2 through the branch pipe A6. The plate heat exchanger 2 transfers the heat in the waste gas to the cavity frame A12 through the branch pipe A6. Then, the nozzle A14 on the cavity frame A12 heats the photovoltaic glass entering the annealing furnace body 7, thereby facilitating the recovery and utilization of heat in the waste gas and facilitating the preheating treatment of the photovoltaic glass, thus improving the processing efficiency of photovoltaic glass.
