Description

Technical Field

[0001] This utility model relates to the field of glass flow channel suction and sweeping technology, and in particular to a float glass flow channel suction and sweeping device. Background Technology

[0002] Float glass production involves floating molten glass on the surface of molten tin, followed by cooling and shaping processes to create flat glass. The runner, as a crucial channel connecting the melting furnace and the tin bath, plays a decisive role in the transfer of molten glass and the quality of the finished product. In actual production, the runner is constantly exposed to temperatures exceeding 1000℃. Volatile substances in the molten glass (such as sulfates and alkali metal oxides) condense and deposit on the inner walls and top of the runner, forming a stubborn layer of dirt. Simultaneously, debris generated by the high-temperature scouring of the runner bricks and dust from the external environment also adhere to the runner surface. If these contaminants are not cleaned promptly, they can fall into the molten glass, causing serious defects such as bubbles, stones, and optical distortion in the glass sheets, directly affecting the yield and quality of the finished product. Currently, the cleaning of float glass runners mainly employs two methods: manual cleaning and simple mechanical equipment. Manual cleaning typically uses tools such as shovels and brushes, with workers manually scraping away dirt from the surface of the flow channel in high-temperature environments. This method is not only labor-intensive and inefficient, but also poses safety hazards such as burns and falls. Publication number CN202224405U discloses a float glass flow channel suction and cleaning device, relating to the field of glass flow channel suction and cleaning technology. It includes a high-temperature resistant housing with an exhaust fan inside. The exhaust fan's suction port is connected to the outlet of a metal suction hose, which is also connected to a dust bag. The inlet of the metal suction hose is connected to a heat-resistant steel pipe. While this device can remove condensate, it cannot completely remove stubborn dirt adhering to the upper wall of the flow channel using only the fan, requiring improvement. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problems mentioned in the background art.

[0004] This utility model adopts the following technical solution: a float glass flow channel suction and sweeping device, including a housing, a rotating shaft A rotatably connected inside the housing, a roller brush fixedly connected to the surface of the rotating shaft A, a gear A fixedly connected to the surface of the rotating shaft A, a protective box fixedly connected to the inner surface of the housing, a motor fixedly connected inside the protective box, a gear C fixedly connected to the output end of the motor, a gear B rotatably connected inside the housing, a limit rod fixedly connected to the inner surface of the housing, a vertical rod slidably connected inside the limit rod, a spring sleeved on the surface of the vertical rod, a slider rotatably connected to one end of the vertical rod, a sliding rod slidably connected inside the slider, scrapers fixedly connected to both ends of the sliding rod, a rotating shaft B rotatably connected inside the scraper, and a guide plate fixedly connected inside the housing.

[0005] Preferably, gear A meshes with gear B, and gear B meshes with gear C. Here, the motor acts as the power source, driving gear C to rotate after startup. Through the transmission of gear B, the power is transmitted to gear A, thereby driving the rotating shaft A to rotate. The gear transmission structure features a stable transmission ratio and high transmission efficiency, ensuring that the roller brush performs cleaning operations at a constant speed. This gear transmission system can stably and efficiently transmit the motor's power to the roller brush, ensuring that the roller brush continuously and evenly cleans the surface of the flow channel, effectively removing accumulated dust and debris from the surface of the flow channel. This avoids the problem of incomplete cleaning caused by unstable power transmission, improves the cleaning effect and working stability of the suction and sweeping device, and also increases the overall service life of the device.

[0006] Preferably, one end of the spring is fixedly connected to the surface of the upright, and the surface of the slider is slidably connected to the interior of the scraper. Here, the elastic adjustment structure allows the scraper to adapt to the complex shape of the flow channel surface, maintaining a good fit and effectively removing stubborn dirt and debris. The spring's cushioning effect also prevents rigid collisions between the scraper and the flow channel surface, reducing damage to both the scraper and the flow channel, extending equipment lifespan, and improving cleaning efficiency and quality. This solves the problem of traditional suction and sweeping devices struggling to handle complex flow channel surfaces.

[0007] Preferably, the surface of the rotating shaft B is fixedly connected to the interior of the housing, and the surface of the guide plate is fixedly connected to the surface of the protective box. Here, the rotating shaft B ensures the stability and flexibility of the scraper rotation, and the guide plate effectively improves the flow path of debris, allowing debris to be sucked into the air intake more smoothly, reducing the risk of blockage, improving suction and sweeping efficiency, and also helping to keep the inner cavity of the housing clean and reduce maintenance frequency.

[0008] Preferably, a fan is fixedly connected inside the housing, a filter box is fixedly connected to the output end of the fan, a filter screen is fixedly connected inside the filter box, a cooling box is fixedly connected to the side of the filter box, an air cooler is fixedly connected inside the cooling box, an air duct is fixedly connected to the side of the cooling box, and an air intake is fixedly connected to one end of the air duct. Here, this dust collection and filtration structure can efficiently collect debris in the flow channel. The multi-layer filter design effectively prevents large particles from entering the fan, avoiding fan blockage and damage, and extending the fan's service life. The air cooler (model TL-5) cools the intake air, reducing its temperature and preventing high-temperature air from damaging subsequent equipment, ensuring the stable operation of the entire suction and sweeping device. It also reduces the environmental impact of high-temperature debris, improving the safety and reliability of the device.

[0009] Preferably, the surfaces of the filter box and cooling box are fixedly connected to the inner surface of the housing, the surface of the air duct is fixedly connected to the interior of the housing, and one end of the air intake is fixedly connected to the surface of the guide plate. Here, the filter box, cooling box, and housing are securely connected by bolts, welding, or other methods to ensure that no displacement or loosening occurs during device operation. The air duct is embedded inside the housing and sealed with a sealant to prevent air leakage from affecting suction power. The air intake is tightly connected to the guide plate, ensuring that debris can be smoothly drawn into the air duct. This stable connection and fixing method ensures the sealing and stability of the entire dust collection system, preventing a decrease in suction power due to loose components or air leakage, and ensuring that the vacuuming device can operate continuously and efficiently.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. This utility model incorporates components such as a roller brush, a limiting rod, a spring, a vertical rod, a scraper, and a guide plate. A motor drives gear C to rotate, which in turn drives gears B and A, thus rotating the roller brush to clean the flow channel. Simultaneously, hard-to-remove condensate is further removed by the scraper. The scraper, under the action of the vertical rod and spring, adheres well to the upper surface of the flow channel for effective scraping. The extended portion effectively reduces the amount of dirt cleaned by the roller brush falling into the glass fluid below, and the guide plate collects the dirt for better operation of the subsequent vacuuming device.

[0012] 2. This utility model incorporates a filter box, filter screen, cooling box, and air cooler. The condensate removed is at a high temperature. The fan draws it into the cooling box through the air inlet, where the air cooler rapidly lowers its temperature. The condensate then passes through the filter box, where the filter plates are multi-stage filters made of different materials to ensure thorough filtration. This cooling and filtration process extends the lifespan of the fan and reduces secondary pollution caused by falling condensate. Attached Figure Description

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1

[0026] Please see Figure 1-6This utility model provides a technical solution: a float glass flow channel suction and sweeping device, including a housing 1, a rotating shaft A3 rotatably connected inside the housing 1, a roller brush 2 fixedly connected to the surface of the rotating shaft A3, a gear A4 fixedly connected to the surface of the rotating shaft A3, a protective box 6 fixedly connected to the inner surface of the housing 1, a motor 7 fixedly connected inside the protective box 6, a gear C8 fixedly connected to the output end of the motor 7, a gear B5 rotatably connected inside the housing 1, a limit rod 9 fixedly connected to the inner surface of the housing 1, a vertical rod 11 slidably connected inside the limit rod 9, a spring 10 sleeved on the surface of the vertical rod 11, and a slider 12 rotatably connected to one end of the vertical rod 11. An internal sliding rod 13 is connected, with scrapers 14 fixedly connected to both ends of the rod 13. A rotating shaft B15 is rotatably connected inside the scraper 14. A guide plate 16 is fixedly connected inside the housing 1. Here, a limiting rod 9 is vertically fixed to the inner surface of the housing 1, forming a hollow tubular structure with a smooth interior, providing guidance for the sliding of the upright rod 11. The guide plate 16 adopts an arc-shaped curved surface design, its curved shape optimized by fluid dynamics, and its surface is polished, resulting in a smooth and flat surface. The guide plate 16 is made of high-temperature and corrosion-resistant alloy plate, capable of withstanding the high temperature and impact of impurities within the flow channel. Gears A4 and B5 mesh with each other, and gear B5 meshes with gear C8. Here, the motor 7 serves as the power source; after starting, it drives gear C8 to rotate, transmitting power to gear A4 through gear B5, thereby driving the rotating shaft A3 to rotate. The gear transmission structure features a stable transmission ratio and high transmission efficiency, ensuring that the roller brush 2 performs cleaning operations at a constant speed. This gear transmission system can stably and efficiently transmit the power of the motor 7 to the roller brush 2, ensuring that the roller brush 2 continuously and evenly cleans the surface of the flow channel, avoiding incomplete cleaning caused by unstable power transmission, improving the cleaning effect and working stability of the suction and sweeping device, and also increasing the overall service life of the device. One end of the spring 10 is fixedly connected to the surface of the upright 11, and the surface of the slider 12 is slidably connected to the interior of the scraper 14. Here, the elastic adjustment structure allows the scraper 14 to adapt to the complex shape of the flow channel surface, and the scraper 14 can maintain a good fit, effectively scraping away stubborn dirt and debris. The buffering effect of spring 10 also prevents the scraper 14 from rigidly colliding with the flow channel surface, reducing damage to the scraper 14 and the flow channel, extending the service life of the equipment, and improving cleaning efficiency and quality. This solves the problem that traditional suction and sweeping devices struggle to handle complex flow channel surfaces. The surface of the rotating shaft B15 is fixedly connected to the interior of the housing 1, and the surface of the guide plate 16 is fixedly connected to the surface of the protective box 6. Here, the rotating shaft B15 ensures the stability and flexibility of the scraper 14's rotation, and the guide plate 16 effectively improves the flow path of debris, allowing it to be more smoothly sucked into the suction port 23, reducing the risk of blockage, improving suction and sweeping efficiency, and also helping to keep the interior of the housing 1 clean and reduce maintenance frequency.

[0027] Example 2

[0028] Please see Figure 2 , Figure 4 , Figure 7-8 A fan 17 is fixedly connected inside the housing 1. A filter box 18 is fixedly connected to the output end of the fan 17. A filter screen 19 is fixedly connected inside the filter box 18. A cooling box 20 is fixedly connected to the side of the filter box 18. An air cooler 21 is fixedly connected inside the cooling box 20. An air duct 22 is fixedly connected to the side of the cooling box 20. An air intake 23 is fixedly connected to one end of the air duct 22. Here, the fan 17 is a high-temperature and high-pressure centrifugal fan. Its impeller and volute are made of special high-temperature resistant alloy materials, which can operate stably in high-temperature environments. The air cooler 21 is (model TL-5). This dust collection and filtration structure can efficiently collect debris in the flow channel. The multi-layer filter screen 19 design can effectively prevent large particles of debris from entering the fan 17, avoiding blockage and damage to the fan 17 and extending the service life of the fan 17. The air cooler 21 cools the intake air, reducing its temperature and preventing damage to downstream equipment. This ensures stable operation of the entire suction and sweeping device and reduces the environmental impact of high-temperature debris, improving the device's safety and reliability. The surfaces of the filter box 18 and cooling box 20 are fixedly connected to the inner surface of the housing 1, the surface of the air duct 22 is fixedly connected to the interior of the housing 1, and one end of the air intake 23 is fixedly connected to the surface of the guide plate 16. Here, the filter box 18 and cooling box 20 are securely connected to the housing 1 using bolts, welding, or other methods to ensure no displacement or loosening occurs during device operation. The air duct 22 is embedded inside the housing 1 and sealed with a sealant to prevent air leakage from affecting suction. The air intake 23 is tightly connected to the baffle 16, ensuring that debris can be smoothly sucked into the air duct 22. This stable connection and fixing method ensures the sealing and stability of the entire dust collection system, avoids the decrease in suction power due to loose parts or air leakage, and ensures that the vacuuming device can work continuously and efficiently. The precise connection between the components also facilitates the installation, debugging and maintenance of the equipment, reduces failures caused by connection problems, and improves the reliability and service life of the equipment.

[0029] Working principle: Install the vacuuming device onto the area to be cleaned in the float glass flow channel, ensuring that the housing 1 is placed stably and that all components are tightly connected without looseness. Check the power connection and operating status of electrical equipment such as motor 7, fan 17, and air cooler 21, confirm that the filter screen 19 is installed in place and undamaged, and ensure that the vacuuming and filtration system is well sealed. Start motor 7, which serves as the power source, and the gear C8 at its output end begins to rotate. Power is transmitted sequentially to gear A4 through the meshing of gear B5 with gears C8 and A4, which in turn drives the rotating shaft A3 to rotate. Since the roller brush 2 is fixed to the surface of the rotating shaft A3, it rotates in a circular motion as the shaft rotates, continuously cleaning the surface of the float glass flow channel. Simultaneously, the scraper 14 operates. When the scraper 14 contacts the flow channel surface, if the flow channel surface is flat and the spring 10 is in its natural state, the scraper 14, supported by the slide rod 13 and the slider 12, adheres to the flow channel surface at a preset angle. When encountering protrusions or depressions on the flow channel surface, the pressure on the scraper 14 changes, causing the upright rod 11 to slide up and down within the limiting rod 9, compressing or stretching the spring 10. The elastic force of the spring 10 keeps the scraper 14 firmly attached to the flow channel surface. When the slider 12 slides in the groove of the scraper 14, the angle of the scraper 14 is finely adjusted, and the adaptive fit to the surface of the flow channel is achieved, effectively scraping away stubborn condensate and other dirt that is difficult to clean by the roller brush 2. The extended part of the housing 1 can prevent the dirt removed by the roller brush 2 and the scraper 14 from splashing and reducing the amount of dirt that enters the glass fluid below. The debris swept by the roller brush 2 and scraped by the scraper 14 moves towards the guide plate 16 under its own gravity and the airflow inside the device. The guide plate 16 adopts an arc-shaped curved surface design optimized by fluid dynamics, and the surface is smooth and flat. After contacting the guide plate 16, the debris will quickly and smoothly converge to the vicinity of the air intake 23 along the guiding direction of the curved surface. The fan 17 is started. The fan 17 adopts a centrifugal structure with high temperature resistance and high air pressure, forming a strong negative pressure inside the device. The air intake 23 is tightly connected to the guide plate 16. Under negative pressure, debris and air gathered near the air intake 23 are drawn into the air duct 22 and into the cooling box 20. The air cooler 21 is activated, and the hot air in the duct is cooled by forced air cooling to reduce the air temperature and prevent high-temperature air from damaging subsequent equipment, ensuring the stable operation of the entire suction and sweeping device. At the same time, it reduces the impact of high-temperature debris on the environment. After cooling, the air containing debris enters the filter box 18, where it is effectively filtered by the multi-stage filter screen 19 to prevent the fan 17 from being blocked or damaged by the suction of debris. After cleaning a specific area of ​​the flow channel, the suction and sweeping device can be moved to the next area to continue the work, or the motor 7, fan 17, air cooler 21, and other equipment can be turned off to stop the cleaning work. At this time, the filter box 18 can be opened to clean the collected debris and check and replace the filter screen 19 to prepare for the next use.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
