Description

Technical Field

[0001] This invention relates to the technical field, specifically to a modular photovoltaic glass tempering furnace with zoned temperature control and energy-saving device. Background Technology

[0002] A photovoltaic glass tempering furnace is a device that physically processes glass by passing it through a heating zone and a rapid cooling zone. The technology of heating the glass and then rapidly cooling it creates compressive stress on the surface of the cooled glass and tensile stress inside the glass, thereby increasing the strength of the glass and turning ordinary annealed glass into tempered glass.

[0003] Patent document CN202323237244.5, entitled "A Multi-Station Glass Tempering Furnace," describes a process where glass is placed on a conveyor roller assembly and transported through rectangular through-holes into a secondary high-temperature heating chamber for heating. After reaching the secondary high temperature, the glass is conveyed by the conveyor roller assembly into a rapid cooling chamber for rapid cooling. Existing photovoltaic glass tempering furnaces share the same technical solution, with the heating zone and rapid cooling zone directly connected. This direct contact between the hot air in the heating zone and the cold air in the rapid cooling zone hinders zoned temperature control and results in wasted electrical energy used for temperature control in both zones.

The interior of the furnace is divided into a heating zone and a quenching zone by the upper partition and the lower partition. There is a through groove between the upper partition and the lower partition. The furnace body is equipped with a lifting assembly, which is used to drive the heat insulation plate to rise and fall. The front and rear sides of the heat insulation plate are in contact with the inner wall of the furnace body, and the heat insulation plate is used to seal the through groove.

[0006] Preferably, the lifting assembly includes an electric telescopic rod vertically mounted on the furnace body, a connecting rod on the output end of the electric telescopic rod, the connecting rod being slidably connected to the upper partition, and the bottom of the connecting rod being connected to the heat insulation plate.

[0007] Preferably, the top of the upper partition is provided with a slot, and the heat insulation plate is fitted and connected to the slot.

[0008] Preferably, the top of the lower partition is provided with a slot that matches the heat insulation plate.

[0009] Preferably, a connecting rod is attached to the bottom inner wall of the slot, and a blocking block is provided at both the front and rear ends of the connecting rod.

The connecting rod is located below the heat insulation plate, the top of the blocking block is aligned with the top of the lower partition, and the front and rear blocking blocks on both sides penetrate through the front and rear ends of the furnace body.

[0010] Preferably, the top of the front block has an insertion hole, the front of the furnace body has an installation frame, the installation frame has a geared motor, the output end of the geared motor has a rotating shaft, the rotating shaft is connected to the installation frame through a bearing, the rotating shaft has a gear, the rear side of the gear is meshed with a rack, the bottom of the rack has an insertion rod, and the insertion rod is inserted into the insertion hole. The installation frame has a vertical slide rail, and the rack is slidably connected to the slide rail.

[0011] Preferably, the front side of the gear is meshed with a rack, and the rack is slidably connected to a slide rail mounted on the mounting frame.

[0012] Preferably, both ends of the front side of the furnace body are provided with protrusions, and the front side of the front block is provided with a protruding rod that contacts both protrusions.

[0014] Preferably, the dust collection trough is located directly below the front block, the bottom of the dust collection trough has an installation hole that communicates with the support pipe, and a filter screen is provided on the inner wall of the installation hole.

[0015] This invention provides a modular photovoltaic glass tempering furnace with zoned temperature control and energy saving device. Compared with the prior art, it has the following advantages: 1. This modular photovoltaic glass tempering furnace zone temperature control and energy-saving device uses a lifting component to drive a heat insulation plate to seal the passage between the heating zone and the rapid cooling zone for the entry and exit of photovoltaic glass. This prevents hot air and cold air from directly contacting each other and affecting the zone temperature control when the heating zone and the rapid cooling zone heat and cool the photovoltaic glass inside, thereby reducing the waste of electricity in the heating zone and the rapid cooling zone.

[0016] 2. This modular photovoltaic glass tempering furnace zoned temperature control and energy-saving device has slots on the lower partition plate, which allow the insulation board to be inserted into the slots when sealing the through groove. This ensures that even if dust and impurities adhere to the top of the lower partition plate, the insulation board can still seal the through groove, thus improving the energy-saving effect.

[0017] 3. This modular photovoltaic glass tempering furnace zoned temperature control and energy-saving device allows dust and impurities in the slots to be removed from the furnace body by removing the blocking block and connecting rod. This prevents the slots from accumulating dust and impurities after long-term use, which would affect the entry of the heat insulation board into the slots. The gear-driven rack moves down to fix the blocking block. When the blocking block is removed, the rack moves down to contact the top rear side of the connecting rod, and then the connecting rod and blocking block are reinstalled. In conjunction with the dust collection trough, all dust and impurities on the connecting rod can be completely removed and collected. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] See Figures 1-8 The present invention provides the following two technical solutions: First implementation: A modular photovoltaic glass tempering furnace zoned temperature control and energy-saving device, including furnace body 1 and roller conveyor 2, the roller conveyor 2 being used to transport photovoltaic glass; Both sides of the furnace body 1 are provided with inlet and outlet slots 3 for photovoltaic glass to enter and exit the furnace body 1; The upper and lower sides of the inner wall of the furnace body 1 are respectively provided with an upper partition 4 and a lower partition 5. The interior of the furnace body 1 is divided into a heating zone 6 and a rapid cooling zone 7 by the upper partition 4 and the lower partition 5. The heating zone 6 and the rapid cooling zone 7 are provided with temperature control structures for heating and rapid cooling, including a temperature controller structure, which is existing technology and will not be described in detail here. There is a through groove 8 between the upper partition 4 and the lower partition 5 for the photovoltaic glass in the heating zone 6 to enter the rapid cooling zone 7. The furnace body 1 is equipped with a lifting assembly, which is used to lift the heat insulation plate 9. The front and rear sides of the heat insulation plate 9 are in contact with the inner wall of the furnace body 1, and the heat insulation plate 9 is used to seal the through groove 8. This prevents hot air and cold air from directly contacting each other when the heating zone 6 and the rapid cooling zone 7 heat and cool the photovoltaic glass inside them, thus avoiding the problem of affecting the zone temperature control and reducing the waste of electrical energy in the heating zone 6 and the rapid cooling zone 7.

[0022] The lifting assembly includes an electric telescopic rod 10 vertically mounted on the furnace body 1, which is powered and controlled by existing technology. A connecting rod 11 is provided on the output end of the electric telescopic rod 10. The connecting rod 11 is slidably connected to the upper partition 4. The bottom of the connecting rod 11 is connected to the heat insulation plate 9. The electric telescopic rod 10 drives the heat insulation plate 9 to rise and fall through the connecting rod 11.

[0023] The top of the upper partition 4 has a slot 12, and the heat insulation plate 9 is fitted and connected to the slot 12, so that when the heat insulation plate 9 moves up to make room for the through groove 8, it can be stored in the slot 12. In this way, the vertical distance of the through groove 8 does not need to be very large to meet the upward movement of the heat insulation plate 9.

[0024] Dust and impurities easily accumulate on the top of the lower partition 5, which can affect the seal between the heat insulation plate 9 and the lower partition 5, resulting in some contact between hot and cold air. Therefore, a slot 13 matching the heat insulation plate 9 is provided on the top of the lower partition 5, so that the heat insulation plate 9 can be inserted into the slot 13 when sealing the through groove 8. In this way, even if dust and impurities accumulate on the top of the lower partition 5, the heat insulation plate 9 can still seal the through groove 8, thus improving the energy-saving effect.

[0025] Dust and impurities will accumulate on the inner wall of the bottom of slot 13. Over time, this will affect the insertion of the heat insulation plate 9 into slot 13. Therefore, it needs to be cleaned regularly. Thus, a connecting rod 15 is attached to the inner wall of the bottom of slot 13. Blocks 14 are provided at both ends of the connecting rod 15. The front and rear sides of the heat insulation plate 9 are also in contact with the opposite sides of the two blocks 14 to ensure a seal. The connecting rod 15 is located below the heat insulation plate 9 and does not affect the lifting and lowering of the heat insulation plate 9. The top of the block 14 is aligned with the top of the lower partition 5 to ensure that the dust and impurities on the inner walls of both sides of slot 13 can be pushed away when passing through slot 13. The front and rear blocks 14 also penetrate the front and rear ends of the furnace body 1 to facilitate the removal of the blocks 14.

[0026] To ensure stability, the block 14 needs to be fixed. Therefore, an insertion hole 16 is provided on the top of the front block 14. A mounting frame 17 is provided on the front of the furnace body 1. A geared motor 18 powered by existing technology is provided on the mounting frame 17. A rotating shaft 19 is provided at the output end of the geared motor 18. To improve the stability of the rotating shaft 19, the rotating shaft 19 is connected to the mounting frame 17 through a bearing. A gear 20 is provided on the rotating shaft 19. A gear 22 is meshed on the rear side of the gear 20. An insertion rod 23 is provided at the bottom of the gear 22 and is inserted into the insertion hole 16. A vertical slide rail 25 is provided on the mounting frame 17, and the gear 22 is slidably connected to the slide rail 25. By inserting the insertion rod 23 into the insertion hole 16, the front block 14 is fixed, thereby fixing the connecting rod 15 and the rear block 14.

[0027] The front side of the gear 20 is meshed with a rack 21. The rack 21 is slidably connected to the slide rail 24 on the mounting frame 17, so that the rack 21 and the rack 22 move in opposite directions. The rack 21 is used to contact the connecting rod 15, so that when the connecting rod 15 is moved, the dust and impurities on it can be pushed away.

[0028] Both ends of the front side of the furnace body 1 are provided with protrusions 26, and the front side of the front block 14 is provided with a protruding rod 27 that contacts both protrusions 26, so that when the block 14 is moved back, it can be positioned by contacting the protrusions 26 with the protruding rod 27.

[0029] The second embodiment differs from the first embodiment in that: a mounting plate 30 is provided directly below the front block 14 of the furnace body 1, a suction fan 28 is provided on the mounting plate 30, a suction pipe 29 is provided on the suction fan 28, and a support pipe 31 is attached to the mounting plate 30 and sleeved on the outside of the suction pipe 29, which can position the support pipe 31. The top of the support pipe 31 is connected to the dust collection tank 32. The dust collection tank 32 is located directly below the front block 14, and an installation hole is opened at the bottom of the dust collection tank 32, which is connected to the support pipe 31. A filter screen 33 is provided on the inner wall of the installation hole, so that dust and impurities on the dust collection tank 32 are drawn into the dust collection tank 32 and filtered by the filter screen 33.

[0030] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0031] In use, the heat insulation plate 9 is inserted into the slot 13 to seal the through groove 8. When it is necessary to clean the dust and impurities in the slot 13, the insert rod 23 is moved upward away from the insertion hole 16, and the block 14 is pulled forward. When it is pulled out, the suction fan 28 is turned on. The rear block 14 pushes the dust and impurities on the inner walls of both sides of the slot 13 onto the connecting rod 15. When the rear block 14 is aligned with the rear side of the toothed rod 21, the movement stops. Then the insert rod 23 is moved upward again, so that the toothed rod 21 moves downward to contact the front side of the rear block 14 and also to contact the top rear side of the connecting rod 15. At this time, the block 14 and the connecting rod 15 are moved backward to ensure that the dust and impurities on the top of the connecting rod 15 are pushed away. The dust and impurities on the front side of the top of the connecting rod 15 and the dust and impurities remaining on the rear side of the front block 14 can be cleaned manually. When the front block 14 is about to be reset, the insert rod 23 is moved downward again, so that the toothed rod 21 moves upward without blocking the movement of the front block 14. After resetting the front block 14, the insertion rod 23 can be moved down and inserted into the insertion hole 16.
