Description

Technical Field

[0001] This application relates to the field of tempering furnace technology, and in particular to an automatic slag removal tempering furnace. Background Technology

[0002] During the glass tempering process, glass sheets are conveyed through a high-temperature tempering furnace by conveyor rollers. During this process, the glass may crack due to uneven heating or inherent defects, producing glass shards that fall to the bottom of the furnace. Simultaneously, impurities on the glass surface or in the environment may sinter and adhere to the surface of the conveyor rollers at high temperatures.

[0003] In existing technologies, the cleaning of tempering furnaces mainly relies on manual cleaning after periodic shutdowns. This method has many drawbacks: First, manual cleaning requires waiting for the furnace to cool down, which is time-consuming and seriously affects equipment utilization and production efficiency; second, the high temperature and confined environment inside the furnace pose safety risks and health hazards to operators; third, manual cleaning is difficult for firmly adhered impurities on the roller surface and may not be thorough. Residual debris and impurities can scratch the glass surface in subsequent production, leading to a decrease in product yield and potentially affecting the normal operation of the conveyor rollers and the uniformity of heating.

[0004] Therefore, there is an urgent need for a device that can automatically and online clean up slag and impurities from the conveyor rollers inside the tempering furnace to solve the above problems. Summary of the Invention

[0005] The purpose of this application is to provide an automatic slag removal tempering furnace to solve the above-mentioned problems. This application realizes the simultaneous automatic online cleaning of the conveyor rollers and furnace bottom through a drive system, which solves the problem of needing to stop the machine for manual cleaning. It has the advantages of being clean and efficient, ensuring product quality, adapting to high temperature environment, and operating stably and reliably.

[0006] This application achieves the above objectives through the following technical solutions: An automatic slag removal tempering furnace includes a tempering furnace and a conveying roller disposed therein, and also includes a connecting frame, a drive assembly, a conveying roller cleaning assembly and a slag cleaning assembly; The drive assembly is connected to the connecting frame and is used to drive the connecting frame to move horizontally along the conveying direction parallel to the conveying roller; The conveyor roller cleaning assembly is fixedly connected to the top of the connecting frame, and the debris cleaning assembly is fixedly connected to the bottom of the connecting frame; The conveyor roller cleaning assembly includes a first scraper capable of contacting the surface of the conveyor roller; The debris cleaning assembly includes a second scraper capable of contacting the bottom surface of the tempering furnace; The drive assembly can drive the connecting frame and the first and second scrapers fixed thereon to move horizontally, so as to clean the impurities adsorbed on the conveying roller and the slag falling from the bottom of the tempering furnace, respectively.

Figure 1 This description is provided for the convenience of describing this application and for the purpose of simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0022] like Figure 1-4 As shown, an automatic slag removal tempering furnace includes a tempering furnace body 1, a conveying roller 2, a connecting frame 3, a drive assembly, a conveying roller cleaning assembly, and a slag cleaning assembly.

[0023] The tempering furnace body 1 has a conventional structure in the prior art, and its interior is equipped with multiple conveying rollers 2 that are driven by motors and can rotate and convey glass simultaneously. At the bottom of each end of the tempering furnace 1, there is a pull-out hopper 20 for collecting the debris that is swept out.

[0024] The drive assembly provides power to drive the sweeping components to move horizontally. The drive assembly includes a motor 17, a bracket 16, a drive shaft 15, a drive sprocket 13, a driven sprocket 12, a chain 14, a slider 18, a slide rail 19, and a housing 21.

[0025] The bracket 16 is fixedly installed on the outer wall of the tempering furnace 1. The motor 17 is fixedly installed on the bracket 16 by bolts. The output shaft of the motor 17 is coaxially connected to the transmission shaft 15 through a coupling, and the transmission shaft 15 extends into the interior through the furnace wall of the tempering furnace 1. The housing 21 is a long strip box structure, and its two ends are fixedly connected to the inner wall of the tempering furnace 1 by fasteners, which is used to provide support and protection for the internal transmission components.

[0026] The drive sprocket 13 is coaxially fixed to the end of the transmission shaft 15 located inside the housing 21. The driven sprocket 12 is rotatably connected to the other end of the housing 21 near the tempering furnace 1 via a rotating shaft. The chain 14 is wrapped around the drive sprocket 13 and the driven sprocket 12. The slide rail 19 is fixedly installed along the length of the housing 21 at its outer bottom. The lower part of the slider 18 forms a sliding fit with the slide rail 19, and the upper part passes through the opening at the bottom of the housing 21 and is fixedly connected to the chain 14 by bolts. Therefore, when the motor 17 is started, the drive sprocket 13 is driven to rotate through the transmission shaft 15, thereby driving the chain 14 to rotate cyclically, and thus driving the slider 18 to perform a stable horizontal reciprocating motion along the slide rail 19.

[0027] The connecting frame 3 is a frame structure welded from structural steel, with mounting surfaces reserved at the top and bottom. The upper end of the connecting frame 3 is fixedly connected to the slider 18 of the drive assembly by bolts, thus allowing it to move horizontally together with the slider 18. The design of the connecting frame 3 cleverly avoids structures such as the housing 21, ensuring no interference during movement.

[0028] The conveyor roller cleaning assembly is installed on top of the connecting frame 3 and is used to scrape off impurities adsorbed on the surface of the conveyor roller 2. The assembly includes a first support column 4, a first clamping bar 5, a first fastener 6, and a first scraper 7.

[0029] The first support column 4 is a long strip of metal profile, which is horizontally fixed to the top of the connecting frame 3 by bolts, and its length direction is parallel to the axial direction of the conveying roller 2. Two long strip-shaped first clamping strips 5 are fastened to both sides of the first support column 4 by multiple first fasteners 6 (e.g., bolts). The two first clamping strips 5 are in close contact with the first support column 4, with a certain gap between them to accommodate the first scraper 7. By tightening the first fasteners 6, the two first clamping strips 5 can firmly clamp the first scraper 7. During installation, ensure that the top side of the first scraper 7 is in slight contact with the lower surface of all conveying rollers 2 and covers the entire axial width of the conveying rollers 2.

[0030] A debris removal assembly is installed at the bottom of the connecting frame 3 to scrape away debris that falls from the bottom of the tempering furnace 1. The assembly includes a second support column 8, a second clamping bar 9, a second fastener 11, and a second scraper 10.

[0031] The second support column 8 is also a long strip of metal profile, which is horizontally fixed to the bottom of the connecting frame 3 by bolts and aligned vertically with the first support column 4. Two long strips of second clamping strips 9 are fastened to both sides of the second support column 8 by multiple second fasteners 11 (e.g., bolts). The two second clamping strips 9 fit snugly against the second support column 8, with a gap between them to accommodate the second scraper 10. By tightening the second fasteners 11, the two second clamping strips 9 can firmly clamp the second scraper 10. During installation, ensure that the bottom side of the second scraper 10 is in slight contact with the furnace bottom surface of the tempering furnace 1 and covers the entire width of the furnace bottom.

[0032] Both the first scraper blade 7 and the second scraper blade 10 are made of wear-resistant and high-temperature resistant (temperature resistance up to 700℃ or higher) flexible materials, such as high-performance high-temperature resistant silicone or special graphite materials. The flexibility ensures full contact with the cleaning surface, improving cleaning efficiency; the high-temperature resistance guarantees long-term stable operation in the high-temperature environment of the tempering furnace.

[0033] Working principle: If the glass breaks during the tempering process, shards will fall to the bottom of the furnace or debris will adhere to the conveyor roller 2.

[0034] The motor 17 is started, and the motor 17 drives the drive sprocket 13 to rotate through the transmission shaft 15, which in turn causes the chain 14 to move in a cycle. The slider 18 fixed on the chain 14 then drives the connecting frame 3 to move horizontally back and forth along the conveying direction of the conveying roller 2 (i.e., the glass traveling direction).

[0035] When the connecting frame 3 moves, the first scraper 7 at the top rubs against the surface of the rotating conveyor roller 2, scraping off the impurities adhering to its surface; the second scraper 10 at the bottom moves close to the furnace bottom, scraping the falling slag into the hopper 20 at one end (or both ends) of the tempering furnace.

[0036] Operators can clean up the collected slag by periodically pulling out the hopper 20, without having to stop the furnace to cool it down and enter the interior for cleaning, which greatly improves production efficiency and work safety.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this application.
