Description

Technical Field

[0001] This utility model belongs to the field of glass cleaning technology. Specifically, this utility model relates to an online cleaning device for sulfides on glass surfaces. Background Technology

[0002] During the production of float glass, sulfur in fuel or raw materials generates sulfides (such as SO2) at high temperatures, which are deposited on the glass surface to form "sulfur bloom" defects, resulting in a decrease in light transmittance (industry data shows that the sulfur bloom defect rate can reach 0.5%-2%).

[0003] Currently, traditional processing methods rely on offline cleaning (manual polishing / chemical soaking). Since the glass surface temperature has dropped to room temperature during offline cleaning, the material is firmly bonded to the glass and is not easy to clean. Sometimes multiple rounds of cleaning are required, which wastes energy. In addition, a large amount of wastewater and chemical agents are generated that are difficult to treat.

[0004] Because float glass production is a continuous process that cannot be stopped, the generation of glass sulfides is discontinuous, usually occurring during fire changes or plate modifications. Therefore, the cleaning machine needs to be adjusted according to product quality, being put into use when there are many sulfides and cut out when the product quality is stable. Furthermore, current float glass production lines are not equipped with corresponding sulfide cleaning devices, making online cleaning impossible, and the equipment has a compact structure that cannot be modified or added during shutdown.

[0005] Utility model patent CN219309505U, published on July 7, 2023, discloses an online cleaning device for float glass roller conveyors. This device includes a water tank, a sulfur dioxide gas source, and a sulfur dioxide jet pipe. The water tank has an air inlet, a water inlet, and a mixing outlet. The water inlet is connected to the water source. The outlet of the sulfur dioxide gas source is connected to the water tank through the air inlet and is located below the water level. The mixing outlet is located at the top of the water tank and connected to the sulfur dioxide jet pipe, which is positioned below the glass conveying rollers. The sulfur dioxide jet pipe has multiple air outlets, with the air outlets pointing towards the glass conveying rollers. However, this online cleaning device does not solve the aforementioned technical problem. Utility Model Content

[0024] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of this invention, and to facilitate its implementation.

[0025] like Figures 1 to 3As shown, the online cleaning device for sulfides on glass surfaces includes a frame 1. The top of the frame 1 is provided with a brush roller 2 and a sponge roller 3, with the brush roller 2 located between the sponge rollers 3. The top of both ends of the frame 1 are connected to bearing seats 5. Both the brush roller 2 and the sponge roller 3 are provided with a spindle 4, and the two ends of the spindle 4 are rotatably connected to the bearing seats 5. The end of the frame 1 is provided with a motor 6 and a screw lift 7, and the bottom of the frame 1 is provided with casters 8. The frame 1 is constructed from multiple square tubes welded together to form a frame structure, which is compact and has low manufacturing cost. The motor 6 provides power for the rotation of the brush roller 2 and sponge roller 3 via a synchronous belt drive. The screw jack 7 can change the height of the device and can be used alternately with the casters 8, allowing it to be moved into and removed from the cold end production line at any time. Maintenance does not affect normal production. The device has a compact structure and independent design, and can be embedded in the float glass cold end equipment without modifying the cold end equipment. Its operation can be carried out under continuous production conditions. The design spacing and device elevation of the mandrel 4 are based on the cold end equipment design to achieve non-destructive embedding into the cold end equipment. This allows it to enter or exit the cleaning process at any time according to the glass quality, and to be started or stopped at any time according to the product quality.

[0026] The device is arranged from front to back as follows: a first sponge roller 3, two brush rollers 2, and a second sponge roller 3. The first sponge roller 3 is used to wet the glass and soften sulfides, the two brush rollers 2 clean the sulfides on the glass surface, and the second sponge roller 3 scrubs the glass and removes a large amount of water droplets. The brush rollers 2 and sponge rollers 3 are at the same height and arranged parallel to each other. An air knife can be additionally installed on one side of the second sponge roller 3 to dry the glass. The arrangement of the brush rollers 2 and sponge rollers 3 can effectively remove sulfides from the glass surface in a timely manner, realizing online wetting, soaking, cleaning, scrubbing, and drying functions.

[0027] like Figure 4 As shown, mounting seats 9 are fixedly connected to the inner sides of both ends of the frame 1. The screw jack 7 is fixed to the bottom of the mounting seats 9. The screw jack 7 includes a screw 12, with a flange 13 connected to the bottom of the screw 12. The top of the screw 12 passes through the mounting seat 9, and a connecting plate 14 connects the flanges 13. The screw jack 7 includes a reducer 11 and a drive motor 10. The drive motor 10 drives the screw 12 to rise and fall by driving the nut inside the reducer 11. This screw jack 7 is a commonly used structure in the prior art. The flanges 13 and the connecting plate 14 increase the support area of ​​the device and ensure the support stability of the device. The two flanges 13 located at the same end of the frame 1 are also connected by the connecting plate 14 to further increase the contact area with the ground and improve stability. The mounting seats 9, screw jack 7, and other components are all installed on the inner side of the end of the frame 1, without spatial interference with the platform 15 or the motor 6.

[0028] like Figures 1 to 3As shown, casters 8 facilitate the movement of the entire device. The screw jack 7 serves as the screw jack mechanism. When the connecting plate 14 supports the ground, the entire device is lifted by the screw jack 7 to adapt to the height of the cold-end equipment. When the screw jack 7 drives the connecting plate 14 to detach from the ground, the casters 8 contact the ground, allowing the entire device to be lowered below the cold-end equipment for removal and maintenance without affecting normal production. Simultaneously, all four screw jacks 7 can operate simultaneously or individually. Each corner of the device can be adjusted independently without requiring ground leveling, simplifying operation and allowing for adjustments to the equipment's elevation regardless of the ground level. The external control system enables one-button lifting and lowering for start-up or switching to standby. The aforementioned screw jack 7 mechanism can also be replaced with pneumatic cylinders, hydraulic cylinders, etc.

[0029] like Figures 1 to 3 As shown, there are two brush rollers 2 and two sponge rollers 3. The two sponge rollers 3 are located on the top sides of the frame 1, and the brush roller 2 is located between the two sponge rollers 3. The brush roller 2 and the sponge roller 3 are arranged in parallel. During the glass conveying process, the glass is first wetted by the sponge roller 3, then cleaned by the two brush rollers 2 through rotation, and then wiped by the sponge roller 3. This can improve the cleaning effect of sulfides on the glass surface and ensure product quality.

[0030] like Figure 2 As shown, a platform 15 is fixedly connected to the outer side of one end of the frame 1. The motor 6 is mounted on the platform 15, and the output end of the motor 6 is connected to a drive wheel 16. The end of the spindle 4 is provided with a driven wheel 17 corresponding to the drive wheel 16. The platform 15 is used to mount the motor 6 horizontally. Each spindle 4 is provided with a driven wheel 17 at its end. The two motors 6 provide power for the rotation of the brush roller 2 and the sponge roller 3 by synchronous belt drive.

[0031] like Figure 4 As shown, water tanks 18 are provided below both the brush sleeve 22 and the sponge roller 3. The two ends of the water tank 18 are fixedly connected to the frame 1, and one end of the bottom of the water tank 18 is provided with an interface 19. The water tank 18 can collect the wastewater after cleaning the glass by the brush sleeve 22 and the sponge roller 3 and pass it into the water system circulation treatment device to realize the timely discharge and treatment of wastewater. The multiple interfaces 19 can also achieve the function of supplying clean water, and also facilitate the installation of an online circulation filtration device in the water circuit, thereby providing the functions of clean water supply and water conservation.

[0032] like Figure 5 As shown, the top of the frame 1 is provided with pads 20 at both ends, and the bearing seats 5 are located above the pads 20. The bearing seats 5 are connected to the pads 20 at both ends with connecting bolts 21. The installation height of each bearing seat 5 can be adjusted by connecting bolts 21, so that each spindle 4 can be adjusted individually as needed to meet the fine adjustment of the height of the brush roller 2 and the sponge roller 3.

[0033] like Figure 6As shown, the brush roller 2 includes a brush sleeve 22, and the sponge roller 3 includes a sponge sleeve 23. Each brush roller 2 has three brush sleeves 22 on its spindle 4, and each sponge roller 3 has three sponge sleeves 23 on its spindle 4. In this structure, both the brush sleeves 22 and the sponge sleeves 23 are fitted onto the spindle 4. When a brush sleeve 22 or sponge sleeve 23 on a particular spindle 4 needs to be replaced, only the corresponding sleeve needs to be replaced, reducing the high cost of overall replacement.

[0034] This online glass surface sulfide cleaning device replaces the traditional offline cleaning method, effectively removing sulfides from the glass surface in a timely manner. It avoids the problem of difficulty in cleaning once the glass surface temperature drops to room temperature, reducing wastewater production, labor costs, and the use of chemical agents. With the screw jack 7 and casters 8, the device can be adjusted for operation or removal based on product quality requirements, meeting the needs of continuous float glass production and scenarios where downtime for modification and expansion is difficult. It solves the problem of the inability to clean glass sulfides online on float glass production lines. This online cleaning device also boasts advantages such as convenient operation, easy adjustment, and a compact structure.
