Description

Technical Field

[0001] This utility model relates to the field of glass melting technology, specifically to a glass melting electric furnace. Background Technology

[0002] Glass melting is one of the important processes in glass production. It is the process of heating the batch materials at high temperature to form a uniform, bubble-free molten glass that meets the forming requirements. The melting process is divided into five stages: silicate formation, glass formation, refining, homogenization and cooling. Each stage is internally connected and influences the others. Imperfections in each stage will affect the reaction in the next stage and ultimately affect the product quality.

[0003] Because the furnace is stirring during the process of melting glass raw materials, the stirring of the molten raw materials at high temperature will cause the raw materials to splash into the furnace lid. After long-term use, a large amount of solution will splash out of the furnace lid. This is because chemical raw materials are added as catalysts during glass melting. When the catalyst splashes onto the furnace lid, it will cause corrosion of the furnace lid.

[0004] Therefore, those skilled in the art provide a glass melting furnace to solve the problems mentioned in the background art. Utility Model Content

[0036] As one implementation method in this embodiment, please refer to Figure 4 and Figure 6 As shown, the flipping mechanism 6 includes a first fixing plate 601 fixedly disposed on the outside of the reinforcing plate 8. Two fixing lugs 602 are fixedly disposed on the upper end of the first fixing plate 601. A positioning block 603 is movably connected to one end of the first fixing plate 601 away from the two fixing lugs 602. A hydraulic shaft 604 is fixedly sleeved inside the positioning block 603. A connecting shaft 605 is fixedly disposed at the top of the hydraulic shaft 604. L-shaped connecting blocks 607 are movably connected to both sides of the connecting shaft 605.

The L-shaped connecting block 607 is located between the hydraulic shaft 604 and the furnace cover 4 and is movably connected between the two fixing lugs 602 at the upper end of the first fixing 601. When the hydraulic shaft 604 extends upward, it presses down on the furnace cover 4.

[0038] As one implementation method in this embodiment, please refer to Figures 7-8 As shown, the tilting mechanism 7 includes multiple second hydraulic cylinders 701 fixed to the base plate 1. A stabilizing bracket 702 is fixedly connected to the upper end of the multiple second hydraulic cylinders 701. A transmission fixing plate 703 is fixedly provided on the upper end of the stabilizing bracket 702. Multiple sets of transmission shafts 704 are arranged at equal intervals inside the transmission fixing plate 703. A transmission belt 705 is fitted on the outside of the multiple sets of transmission shafts 704.

[0039] The curvature of the transmission fixing plate 703 of the tilting mechanism 7 is consistent with the curvature of the bottom of the furnace 3. When the second hydraulic cylinder 701 extends upward, it can press the transmission belt 705 against the bottom of the furnace 3.

[0040] Working principle: When using furnace 3, the hydraulic shaft 604 is activated to retract, opening the furnace cover 4. The operator then feeds and melts the glass raw materials. After the glass is melted, the furnace cover 4 is opened, and the first motor 403 is activated to rotate the scraper 404 along the groove 401 inside the furnace cover 4, scraping away the splashed glass solution inside the groove 401. The glass solution drips along the edge of the groove 401 into the drip trough 303, thus preventing the glass solution from falling into the furnace 3. The bottom of the furnace 3 is equipped with a tilting mechanism 7. When the operator needs to remove the glass solution, the second hydraulic cylinder 701 is activated, pressing the tilting mechanism 7 against the bottom wall of the furnace 3. Then, the second motor servo 707 of the tilting mechanism 7 is activated to rotate forward, moving the bottom of the furnace 3 away from the discharge port 302, allowing the molten glass to flow out along the discharge port 302. After tilting, the second motor servo 707 is turned off, and the third motor servo 708 is activated to rotate in the reverse direction, making the bottom of the furnace 3 perpendicular to the bottom plate 1.
