Description

Technical Field

[0001] This utility model relates to the field of photovoltaic glass production technology, specifically to a device for improving the atmosphere in the cooling section of the passageway. Background Technology

[0002] During the production of photovoltaic glass, when the molten glass passes through the cooling section of the furnace, volatile gases generated by the furnace accumulate in the cooling section. These gases contain sulfur and nitrates, which, upon condensation, form sulfates and nitrates. These sulfates and nitrates are adsorbed onto the flow channel openings and the cooling section arch, creating a "curtain" phenomenon. When these drips reach a certain size, they will fall onto the surface of the molten glass, affecting the quality of the glass production. Furthermore, these drips can cause significant damage to the rollers of the rolling mill, increasing their operating costs and further raising the overall cost of glass production.

[0003] Therefore, there is an urgent need for a device to improve the atmosphere in the cooling section of the passage to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a device for improving the atmosphere of the cooling section of the passage, so as to solve the problem mentioned in the background art of large amounts of sulfate and nitrate adhering to the flow channel opening and the cooling section arch.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an apparatus for improving the atmosphere of the cooling section of the passage, including a kiln, and further including a processing component disposed in the kiln for treating volatile gases inside the kiln;

[0006] The processing component includes a fixed frame disposed on one side of the kiln, an exhaust fan mounted on one side of the fixed frame, a chimney at the exhaust fan outlet, a processing pipe at the exhaust fan inlet, and a processing pipe connected to the kiln cooling section at the end away from the exhaust fan. The processing pipe is equipped with a filter assembly for filtering volatile organic compounds or dust in the volatile gases.

[0007] The processing components are provided in several units and can be respectively set on both sides of the kiln neck and passage (including the main passage and branch passage). During use, the location and number of open processing components can be selected and used according to the pressure inside the furnace and the content of volatile gases.

[0008] The filter assembly includes a mounting hole formed on the side wall of the processing tube. A first mounting frame is slidably connected to the mounting hole. A second mounting frame is connected to one side of the first mounting frame via a connecting component. A filter plate is detachably connected to the first and second mounting frames. The first and second mounting frames are provided with fixing components for fixing to the processing tube.

[0009] The fixing assembly includes a fixing plate fixedly connected to the first mounting frame and the second mounting frame on opposite sides. Mounting plates are fixedly connected to the side walls of the two fixing plates. Threaded rods are threadedly connected to the two mounting plates. Threaded holes are opened on the two opposite side walls of the processing tube. The two threaded holes are matched with the threaded rods.

[0010] The connecting component includes a connecting hole opened on the side of the first mounting frame near the second mounting frame. The connecting hole is connected to a connecting plate via a connecting shaft. One end of the connecting plate is connected to the second mounting frame. The processing tube is provided with a limiting component for limiting the connecting shaft.

[0011] The limiting assembly includes an L-shaped plate fixedly connected to the side of the processing tube away from the fixed frame. A T-shaped rod is slidably connected to the L-shaped plate. A spline rod is connected to one end of the T-shaped rod near the first mounting frame via a circular plate. A spline hole is provided at one end of the connecting shaft near the T-shaped rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention, through the design of its processing components, utilizes an exhaust fan to expel volatile gases from the cooling section of the kiln passage, maintaining a balanced internal pressure within the cooling section. This reduces the amount of gas accumulation in the cooling section without affecting normal production, and inhibits the formation of sulfates and nitrates from gas condensation. It also reduces the amount of sulfates and nitrates adhering to the flow channel openings and cooling section arches, thus mitigating the "curtain" phenomenon and further reducing the amount of dripping material. This not only protects the rolling mill rollers and reduces the risk of damage, but also improves the quality of the produced glass. Attached Figure Description

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

[0021] Please see Figures 1-5 The apparatus shown in the figure is for improving the atmosphere of the cooling section of the passage, including a kiln 1 and a processing component disposed in the kiln 1 for treating volatile gases inside the kiln.

[0022] The processing component includes a fixed frame 201 disposed on one side of the kiln 1. An exhaust fan 203 is provided on one side of the fixed frame 201 via a mounting bracket 202. A chimney 204 is provided at the air outlet end of the exhaust fan 203. A processing pipe 205 is provided at the air inlet end of the exhaust fan 203. The end of the processing pipe 205 away from the exhaust fan 203 is connected to the cooling section of the kiln 1. The processing pipe 205 is provided with a filter component for filtering volatile organic compounds or dust in the volatile gases.

[0023] It should be noted here that: by setting up the processing components, the exhaust fan 203 is used to discharge the volatile gases in the cooling section of the kiln 1 out of the furnace, so as to maintain the internal pressure balance of the cooling section of the kiln 1. This reduces the amount of gas accumulation in the cooling section without affecting the normal production of the cooling section, and plays a certain role in inhibiting the sulfate and nitrate produced by gas condensation. It can also reduce the amount of sulfate and nitrate adhering to the flow channel and the cooling section arch, thereby slowing down the occurrence of the "curtain" phenomenon and further reducing the falling of dripping material from the arch. This not only protects the rolling mill rollers and reduces the risk of damage to the rolling mill rollers, but also improves the quality of the glass produced.

[0024] It is worth noting that in actual use, this processing component can be applied to one kiln with six or eight production lines, and can also be used for one kiln with four or five production lines, etc., which has the flexibility and adaptability of use.

[0025] Please see Figure 1 The diagram shows several processing components that can be installed on both sides of the kiln 1 neck and passage (including the main passage and branch passage). During use, the location and number of open processing components can be selected according to the pressure inside the furnace and the content of volatile gases.

[0026] It should be noted here that by setting up the processing components, the cooling section of kiln 1 is evacuated from the front and back, thereby maintaining the internal pressure balance of the cooling section of kiln 1.

[0027] It is worth noting that the temperature decreases as the molten glass flows through the passage. Therefore, the passage can also be called the cooling section. The various settings of the processing components and their locations at different positions in the furnace 1 can be selected and used according to the furnace pressure and the amount of volatile gases during use, thereby increasing the flexibility of the processing components.

[0028] Please see Figure 3 or Figure 4 The filter assembly shown in the figure includes a mounting hole 301 opened on the side wall of the processing tube 205. A first mounting frame 302 is slidably connected to the mounting hole 301. A second mounting frame 303 is connected to one side of the first mounting frame 302 through a connecting component. A filter plate 304 is detachably connected to the first mounting frame 302 and the second mounting frame 303. The first mounting frame 302 and the second mounting frame 303 are provided with fixing components for fixing to the processing tube 205.

[0029] It should be noted here that: by setting up the filter components, the volatile gases are filtered by the filter plate 304, thereby reducing the damage caused by volatile organic compounds or dust in the volatile gases to the exhaust fan 203, thus ensuring the normal service life of the exhaust fan 203.

[0030] Working principle: When the glass moves to the cooling section of furnace 1, the exhaust fan 203 is started. The suction of the exhaust fan 203 is used to draw air from the cooling section of furnace 1, thereby maintaining the internal pressure balance of the cooling section. This allows a certain amount of gas to be effectively discharged from the cooling section of furnace 1 through the chimney 204 without affecting the normal production of the cooling section. Since the volatile gases in the cooling section of furnace 1 contain some harmful substances, they need to be treated for environmental protection before being discharged. This reduces the amount of gas accumulation in the cooling section and has a certain inhibitory effect on the sulfate and nitrate produced by gas condensation. It can also reduce the amount of sulfate and nitrate adhering to the flow channel and the cooling section arch, thereby slowing down the occurrence of the "curtain" phenomenon and further reducing the falling of dripping material from the arch. This not only protects the rolling mill rollers and reduces the risk of damage to the rolling mill rollers, but also improves the quality of the glass produced.

[0031] Furthermore, when extracting volatile gases from the cooling section of the kiln 1, the volatile gases will be filtered by the filter plate 304 as they pass through the treatment pipe 205, thereby reducing the damage to the exhaust fan 203 caused by volatile organic compounds or dust in the volatile gases, thus ensuring the normal service life of the exhaust fan 203. Example

[0032] Please see Figure 3 or Figure 4 This embodiment further illustrates Example 1. The fixing component shown in the figure includes a fixing plate 401 fixedly connected to the first mounting frame 302 and the second mounting frame 303 on opposite sides. Mounting plates 402 are fixedly connected to the side walls of the two fixing plates 401. Threaded rods 403 are threadedly connected to the two mounting plates 402. Threaded holes 404 are opened on the two opposite side walls of the processing tube 205. The two threaded holes 404 are matched with the threaded rods 403.

[0033] It should be noted here that the setting of the fixing component makes it easy to limit the first mounting frame 302 or the second mounting frame 303, thereby ensuring the stability of the filter plate 304 when used in the processing tube 205.

[0034] Please see Figure 4 or Figure 5 The connecting component shown in the figure includes a connecting hole 501 opened on the side of the first mounting frame 302 near the second mounting frame 303. The connecting hole 501 is connected to a connecting plate 503 through a connecting shaft 502. One end of the connecting plate 503 is connected to the second mounting frame 303. The processing tube 205 is provided with a limiting component for limiting the connecting shaft 502.

[0035] It should be noted here that: by setting the connecting components, the first mounting frame 302 and the second mounting frame 303 are rotatably connected, which facilitates limiting the first mounting frame 302 or the second mounting frame 303 located outside the processing tube 205.

[0036] Please see Figure 4 or Figure 5 The limiting component shown in the figure includes an L-shaped plate 601 fixedly connected to the processing tube 205 on the side away from the fixing frame 201. A T-shaped rod 602 is slidably connected to the L-shaped plate 601. A spline rod 604 is connected to one end of the T-shaped rod 602 near the first mounting frame 302 through a circular plate 603. A spline hole 605 is opened at one end of the connecting shaft 502 near the T-shaped rod 602. The spline hole 605 is matched with the spline rod 604. A spring 606 is sleeved on the side wall of the T-shaped rod 602. The two ends of the spring 606 are respectively connected to the L-shaped plate 601 and the circular plate 603.

[0037] It should be noted here that the setting of the limiting component is used to limit the rotation of the connecting shaft 502, thereby further limiting the first mounting frame 302 or the second mounting frame 303 located outside the processing tube 205, ensuring the stability of the first mounting frame 302 or the second mounting frame 303 when waiting for use outside the processing tube 205.

[0038] Working principle: When the filter plate 304 installed in the treatment pipe 205 becomes dirty and needs to be replaced and cleaned, firstly rotate the threaded rod 403 to disengage it from the threaded hole 404 on the treatment pipe 205. Then pull the T-shaped rod 602 to disengage the splined rod 604 on one side of the circular plate 603 from the splined hole 605 on the connecting shaft 502. Then rotate the second mounting frame 303 to make it flush with the first mounting frame 302. Then push the second mounting frame 303. Under the pushing force, the filter plate 304 on the second mounting frame 303 continuously enters the treatment pipe 205, while the filter plate 304 in the first mounting frame 302 continuously moves out of the treatment pipe 205. Thus, the dirty filter plate 304 can be replaced without stopping the machine, thereby ensuring the continuity of volatile gas treatment in the furnace.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
