Abstract
Description
Technical Field
[0001] This invention relates to the field of float glass production technology, specifically to a graphite block scrubbing device for the transition rollers of the slag box in float glass production. Background Technology
[0002] In the float glass manufacturing process, the slag box stage is one of the key steps to ensure the quality of subsequent glass products. The transition rollers (commonly referred to as "transition rollers") in the slag box are used to smoothly transport the glass sheets from the tin bath to the annealing furnace for further processing. However, during this process, molten tin and tin ash easily adhere to the surface of the transition rollers. If these residues are not removed in time, they will adversely affect the quality of the glass sheets, leading to surface defects.
[0003] Currently, to remove molten solder and solder dust from the surface of the transition roller, graphite blocks are typically installed in a U-shaped groove beneath the roller. Traditional graphite blocks are usually designed in a bullet shape. While this shape allows them to contact the transition roller surface and scrape off some molten solder and solder dust, its structure has significant drawbacks. Due to the bullet-shaped design, the scraped-off molten solder and solder dust easily fall into the gap between the graphite block and the U-shaped groove, causing the graphite block to become stuck and malfunction. This results in surface defects under the glass plate that negatively impact product quality and significantly affect production. Summary of the Invention

[0008] The upper end of the graphite block contacts the surface of the transition roller, and the lower end of the graphite block is installed inside the mounting groove, which is fixedly installed inside the slag box.
[0009] The graphite block has an umbrella-shaped structure at its upper end. The top of the umbrella-shaped structure contacts the surface of the transition roller. The length of the lower end of the umbrella-shaped structure exceeds the length of the opening above the mounting groove, which is used to prevent the scraped molten tin and tin ash from entering the gap between the graphite block and the mounting groove.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components.

[0030] Please see Figures 1-2 This application provides a new technical solution: a graphite block scrubbing device for the transition roller of the slag box in float glass production, including a transition roller 1 installed above the slag box for conveying glass through the tin bath to the annealing furnace, and a graphite block 2 arranged below the transition roller 1 for scraping off the molten tin and tin ash adhering to the surface of the transition roller 1.
[0031] The upper end of the graphite block 2 is in contact with the surface of the transition roller 1, and the lower end of the graphite block 2 is installed inside the mounting groove 3, which is fixedly installed inside the slag box.
[0032] The upper end of the graphite block 2 has an umbrella-shaped structure. The top of the umbrella-shaped structure contacts the surface of the transition roller 1. The lower end of the umbrella-shaped structure extends beyond the length of the opening above the mounting groove 3 to prevent the scraped molten tin and tin ash from entering the gap between the graphite block 2 and the mounting groove 3. The side of the umbrella-shaped structure is inclined to allow the scraped molten tin and tin ash to slide down the inclined surface into the slag box.
[0033] During use, when the transition roller 1 rotates, the conical tip of the graphite block 2 contacts the surface of the transition roller 1, scraping off the molten tin and tin ash through friction. Since the lower end of the umbrella-shaped structure exceeds the opening length of the mounting groove 3, it prevents the molten tin and tin ash from entering the gap. The side tilt angle causes the molten tin and tin ash to slide down the inclined surface to the slag box under the action of gravity. This prevents the molten tin and tin ash from entering the gap and causing the graphite block to jam, ensuring the continuous and stable operation of the scrubbing device, improving the scrubbing efficiency, and thus improving the production quality of float glass.
[0034] In some embodiments, the graphite block 2 has an umbrella-shaped cross-section. This optimizes the flow of molten tin and tin ash, improves cleaning efficiency, prevents molten tin and tin ash from accumulating around the edges, and reduces contamination and potential malfunctions of the equipment.
[0035] In some embodiments, a positioning mechanism is provided at the bottom of the graphite block 2. The positioning mechanism includes a positioning seat 4, which is U-shaped. The bottom of the graphite block 2 is installed inside the positioning seat 4 to position the graphite block 2 inside the mounting groove 3. The positioning seat 4 is slidably disposed inside the mounting groove 3.
[0036] During use, the "U"-shaped structure of the positioning seat 4 stably holds the bottom of the graphite block 2, ensuring it remains in the correct position within the mounting groove 3. This improves the stability and reliability of the scrubbing device, adapts to adjustment needs under different working conditions, and extends the equipment's service life.
[0037] In some embodiments, clamping plates 41 are respectively provided on both sides of the inner wall of the positioning seat 4, and a first spring 42 is respectively provided between the two clamping plates 41 and the positioning seat 4. The elastic force of the first spring 42 causes the clamping plates 41 to generate a clamping force on the graphite block 2. When the graphite block 2 is placed in the positioning seat 4, under the action of the spring force, the clamping plates 41 tightly fit the graphite block 2, adapting to changes in the size and shape of the graphite block 2. Through the cooperation of the first spring 42 and the clamping plates 41, stable clamping of the graphite block 2 is achieved, ensuring that the position of the graphite block 2 is stable and does not shift during the scrubbing process, thereby improving the scrubbing effect.
[0038] In this embodiment, the clamping plates 41 are arranged in a "7" shape, with two clamping plates 41 positioned opposite each other on both sides of the positioning base 4. The two clamping plates 41 are slidably positioned on both sides of the positioning base 4, and the lower end of the graphite block 2 is positioned between the two clamping plates 41. Under the action of the first spring 42, the graphite block 2 is clamped and positioned. This further enhances the clamping and positioning effect of the graphite block 2, ensuring the stability of the graphite block 2's position during the scrubbing process and effectively preventing poor scrubbing results due to the graphite block 2 shaking or shifting.
[0039] In some embodiments, a second spring 5 is provided between the positioning mechanism and the bottom of the mounting groove 3 to push the graphite block 2 to slide inside the mounting groove 3, so that the top of the graphite block 2 contacts the surface of the transition roller 1. The second spring 5 provides an upward thrust. As the graphite block 2 wears during the scrubbing process, the spring pushes the positioning mechanism and the graphite block 2 upward, keeping the top of the graphite block 2 in close contact with the surface of the transition roller 1. This ensures that the scrubbing effect is not affected by the wear of the graphite block, maintains stable scrubbing performance, reduces the frequency of replacement due to graphite block wear, and lowers production costs.
[0040] In some embodiments, the number of graphite blocks 2 is one or more, adjusted according to the length of the transition roller 1. This improves the versatility and adaptability of the device, ensuring effective cleaning of transition rollers 1 of different lengths while reasonably controlling costs and improving production efficiency based on actual conditions.
[0041] In some embodiments, the side tilt angle of the umbrella-shaped structure ranges from 10° to 45°. This optimizes the guiding effect of molten tin and tin ash, ensuring the efficiency and stability of the wiping process, while also ensuring stable contact between the graphite block 2 and the transition roller 1, thus improving the wiping quality.
[0042] Working principle: When using a graphite block scrubbing device for the transition roller of the slag box in float glass production, the first step is to determine the required number of graphite blocks 2 based on the length of the transition roller 1. The bottom of graphite block 2 is installed inside the mounting groove 3 in a U-shaped positioning seat 4. The "7"-shaped clamping plates 41 on both sides of the inner wall of the positioning seat 4 tightly clamp the bottom of graphite block 2 under the action of the first spring 42. When float glass production begins, the transition roller 1 rotates and transports the glass from the tin bath to the annealing furnace. At this time, the umbrella-shaped top of graphite block 2 contacts the surface of the transition roller 1. Under the action of friction, the molten tin and tin ash adhering to the surface of the transition roller 1 are scraped off. Since the lower end of the umbrella-shaped structure of graphite block 2 exceeds the length of the opening above the mounting groove 3, it prevents the scraped molten tin and tin ash from entering the gap between graphite block 2 and mounting groove 3. As graphite block 2 continues to wear, the second spring 5 will continuously provide an upward thrust, pushing the positioning mechanism and graphite block 2 to move upward, keeping the top of graphite block 2 in close contact with the surface of the transition roller 1.
