[0002] A melting furnace is a specialized high-temperature furnace used to melt solid samples at high temperatures to prepare glass slides, molten beads, or liquid melts.

[0003] Glass melting furnaces are used to convert solid glass raw materials into a molten liquid state. Currently, most glass melting furnaces are tilted to facilitate the feeding of molten glass raw materials. However, some solid glass raw materials contain many impurities, resulting in scum forming on the surface of the molten glass. Currently, this scum is mostly removed manually. During manual removal, workers need to be in contact with the high-temperature molten glass for extended periods. Prolonged exposure to high temperatures can harm the workers' health. Furthermore, the removal process requires stable hands and smooth movement of the tools, demanding a high level of operational experience from the workers. Therefore, this application proposes a photovoltaic glass melting furnace and its usage method. Summary of the Invention

[0004] The purpose of this invention is to provide a photovoltaic glass melting furnace and its usage method to solve the problems mentioned in the background art, such as the need for workers to be in contact with molten glass at high temperatures for a long time when manually removing slag, which can cause damage to the workers' health due to prolonged exposure to high temperatures, and the need for workers to have stable hands and move the slag tools smoothly, which requires a high level of operational experience from the workers.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a photovoltaic glass melting furnace, comprising a melting furnace body, a support frame for supporting the melting furnace body, a heating base plate at the bottom of the melting furnace body, and a heating device for heating the glass raw material inside the melting furnace body. The support frame is provided with a central shaft that is rotatably fitted and installed on the melting furnace body, and the heating base plate can rotate relative to the heating device around the center line of the central shaft. A collection pool is provided at the support frame; The collection pool is equipped with a slag scraper and a slag scraping drive mechanism connected to the slag scraper. The slag scraper includes a slag inlet plate and a recessed hopper. The slag scraping drive mechanism is used to drive the slag scraper to move in a direction parallel to the collection pool to scrape away the slag floating on the surface of the collection pool.

[0006] Preferably, a power unit is provided at the support frame, the power unit including a power motor mounted on the support frame, a power shaft drivenly connected to the output end of the power motor, a worm gear mounted on the power shaft, and a worm wheel drivenly connected to the worm gear and mounted on the central shaft.

[0007] Preferably, the support frame is provided with two bearing seats, and the power shaft is inserted into the bearing seats.

[0008] Preferably, the slag scraper hopper is provided with a plurality of separation teeth installed on the slag inlet horizontal plate.

[0009] Preferably, the slag scraping drive mechanism includes a lead screw distributed parallel to the collection tank, a movable frame that is threadedly engaged with the lead screw, a track box mounted on the support frame and slidably engaged with the movable frame, a drive motor mounted on the support frame for driving the lead screw to rotate, and a support plate mounted on the movable frame and connected to the slag scraping hopper.

[0010] Preferably, one end of the support plate is rotatably connected to the movable frame, and the other end of the support plate is fixedly connected to the slag scraper hopper.

[0011] Preferably, the support plate is provided with a rotatably cooperating telescopic unit, and the end of the telescopic unit away from the support plate is rotatably cooperating with the movable frame.

[0012] Preferably, the slag scraper is provided with a rotating support wheel, which includes an inner wheel and an outer wheel. The diameter of the outer wheel is larger than that of the inner wheel. When the slag scraper is scraping the scum inside the collection tank, the outer ring of the inner wheel is tangent to the upper surface of the collection tank.

[0013] Preferably, the support wheels are provided in two sets, and the two sets of support wheels are symmetrically distributed about the center line of the collection pool, and the support frame is provided with a scum collection box.

[0014] A method for using a photovoltaic glass melting furnace includes the following steps: Step 1: Convert the glass raw material into molten glass; heat the glass raw material in the melting furnace body into molten glass using a heating device; Step 2: Transfer the molten glass to the collection tank; turn on the power unit to drive the central shaft and the melting furnace body connected to the central shaft to rotate around the center line of the central shaft, so that the melting furnace body tilts downward and the molten glass inside the melting furnace body enters the collection tank from the furnace nozzle; Step 3: Scrape off the scum on the surface of the molten glass in the collection tank; After the molten glass enters the collection tank and stands for a period of time, start the scum scraping drive mechanism to move the scum scraping bucket along the parallel direction of the collection tank and collect the scum into the recessed hopper.

[0015] Beneficial effects: I. The present invention provides a photovoltaic glass melting furnace and its usage method. The power motor in the power unit is started, which can push the power shaft to rotate, thereby driving the worm gear on the power shaft to rotate. The worm gear cooperates with the worm wheel. The rotating worm gear can drive the worm wheel to rotate. The central shaft inserted into the worm wheel rotates around its own center line and drives the melting furnace body connected to it to rotate. The melting furnace body changes from a vertical state to a downward tilting state. After the melting furnace body is tilted downward, it can be aligned with the collection pool.

The recessed hopper is recessed downwards. Driven by the slag scraping mechanism, the slag inlet plate can move in a direction parallel to the collection pool. During the movement, the slag inlet plate pushes the slag on the surface of the molten glass to gather on one side of the direction of travel. The gathered slag is squeezed and lifted into the interior of the recessed hopper, where it is stored. The recessed hopper is recessed downwards, and its outer wall is submerged in the molten glass. The slag that enters the recessed hopper will not flow into the molten glass outside, thus completing the slag collection work. Attached Figure Description

[0019] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0020] like Figures 1-8 As shown, an embodiment of the present invention provides a photovoltaic glass melting furnace, including a melting furnace body 1, a support frame 3 for supporting the melting furnace body 1, a heating base plate 4 at the bottom of the melting furnace body 1, and a heating device 5 for heating the glass raw materials inside the melting furnace body 1. The heating base plate 4 and the heating device 5 can rotate relative to each other.

[0021] To facilitate the pouring out of the molten glass in the melting furnace body 1, the heating base plate 4 and the heating device 5 are allowed to rotate relative to each other. A central shaft 6 is provided on the support frame 3 and is rotatably fitted onto the melting furnace body 1. The melting furnace body 1 can be pushed to rotate around the central shaft 6, adjusting the orientation of the melting furnace body 1 and sending the molten glass inside the melting furnace body 1 into the collection tank 8.

[0022] In order to drive the furnace body 1 to rotate, a power unit 7 is provided at the support frame 3. The power unit 7 includes a power motor 701 mounted on the support frame 3, a power shaft 702 that is driven and connected to the output end of the power motor 701, a worm gear 703 mounted on the power shaft 702, and a worm wheel 705 that is driven and connected to the worm gear 703 and mounted on the central shaft 6.

[0023] Specifically, the support frame 3 is provided with two bearing seats 704, and the power shaft 702 is inserted into the bearing seats 704.

[0024] It should be noted that collection pools 8 are provided at the support frame 3.

[0025] When the power motor 701 in the power unit 7 starts, it can push the power shaft 702 to rotate, which in turn drives the worm 703 on the power shaft 702 to rotate. The worm 703 cooperates with the worm wheel 705. The rotating worm 703 can drive the worm wheel 705 to rotate. The central shaft 6 inserted into the worm wheel 705 rotates around its own center line and drives the melting furnace body 1 connected to it to rotate. The melting furnace body 1 changes from a vertical state to a downward tilting state. After the melting furnace body 1 tilts downward, it can be aligned with the collection pool 8. The molten glass inside the melting furnace body 1 flows into the collection pool 8 under the action of gravity, completing the feeding of molten glass.

[0026] The glass raw materials may contain some mixed materials. After these materials are melted inside the melting furnace body 1, a layer of slag will float on the surface of the molten glass liquid. In order to remove these slags, a slag scraper hopper 9 and a slag scraper drive mechanism 10 connected to the slag scraper hopper 9 are provided at the collection pool 8. The slag scraper hopper 9 includes a slag inlet horizontal plate 901 and a recessed material bin 902. The slag scraper drive mechanism 10 is used to drive the slag scraper hopper 9 to move in a direction parallel to the collection pool 8 to scrape away the slag floating on the surface of the collection pool 8.

[0027] The lower end of the slag inlet plate 901 is immersed in the molten glass, while the upper end is slightly higher than the height of the molten glass. The recessed hopper 902 is recessed downwards. Driven by the slag scraping drive mechanism 10, the slag inlet plate 901 can move in a direction parallel to the collection tank 8. During the movement, the slag inlet plate 901 pushes the slag on the surface of the molten glass to gather on one side of the direction of travel. The gathered slag is squeezed and lifted into the interior of the recessed hopper 902, where it is stored. The recessed hopper 902 is recessed downwards, and its outer wall is submerged in the molten glass. The slag that enters the recessed hopper 902 will not flow back into the molten glass outside, thus completing the slag collection.

[0028] Specifically, the slag scraper 9 is equipped with several separation teeth 903 installed on the slag inlet horizontal plate 901. As the slag inlet horizontal plate 901 moves, the separation teeth 903 can separate large pieces of floating slag, and the separated floating slag can more easily enter the recessed hopper 902 through the slag inlet horizontal plate 901.

[0029] For details, please refer to Figure 6 , Figure 7 The slag scraping drive mechanism 10 includes a lead screw 1001 distributed parallel to the collection tank 8, a movable frame 1002 that is threadedly engaged with the lead screw 1001, a track box 1004 mounted on the support frame 3 and slidably engaged with the movable frame 1002, a drive motor 1003 mounted on the support frame 3 for driving the lead screw 1001 to rotate, and a support plate 1005 mounted on the movable frame 1002 and connected to the slag scraping hopper 9.

[0030] When the drive motor 1003 starts, it can drive the lead screw 1001 to rotate in both directions. The lead screw 1001 and the moving frame 1002 are connected by threads. Under the drive of the lead screw 1001, the moving frame 1002 can move along the track box 1004 and drive the slag scraper 9 to move to scrape the slag on the outer surface of the molten glass.

[0031] More specifically, one end of the support plate 1005 is rotatably engaged with the movable frame 1002, and the other end of the support plate 1005 is fixedly connected to the slag scraper 9. The support plate 1005 is provided with a rotatably engaged telescopic unit 1006. The end of the telescopic unit 1006 away from the support plate 1005 is rotatably engaged with the movable frame 1002. The telescopic unit 1006 can be an electric telescopic rod.

[0032] It should be noted that the slag scraper 9 is equipped with a rotating support wheel 1007. The support wheel 1007 includes an inner wheel and an outer wheel. The diameter of the outer wheel is larger than that of the inner wheel. When the slag scraper 9 scrapes the scum inside the collection tank 8, the outer ring of the inner wheel is tangent to the upper end face of the collection tank 8. There are two sets of support wheels 1007, and the two sets of support wheels 1007 are symmetrically distributed about the center line of the collection tank 8. The support frame 3 is equipped with a scum collection box 11.

[0033] The telescopic unit 1006 can raise the height of the slag scraper 9, lifting the slag that has entered the slag scraper 9 to a position far away from the liquid level of the molten glass in the collection tank 8, which facilitates the subsequent separation of slag.

[0034] A method for using a photovoltaic glass melting furnace includes the following steps: Step 1: Convert the glass raw material into molten glass; heat the glass raw material in the melting furnace body 1 into molten glass using the heating device 5; Step 2: Transfer the molten glass to the collection tank 8; turn on the power unit 7 to drive the central shaft 6 and the melting furnace body 1 connected to the central shaft 6 to rotate around the center line of the central shaft 6, so that the melting furnace body 1 tilts downward and the molten glass inside the melting furnace body 1 enters the collection tank 8 from the furnace nozzle 2. Step 3: Scrape off the scum on the surface of the molten glass in the collection tank 8; After the molten glass enters the collection tank 8 and stands for a period of time, start the scum scraping drive mechanism 10 to drive the scum scraping bucket 9 to move in the parallel direction of the collection tank 8 and collect the scum into the recessed hopper 902.

[0035] In summary, this invention provides a photovoltaic glass melting furnace and its usage method. When the power motor 701 in the power unit 7 is started, it pushes the power shaft 702 to rotate, which in turn drives the worm gear 703 on the power shaft 702 to rotate. The worm gear 703 cooperates with the worm wheel 705. The rotating worm gear 703 drives the worm wheel 705 to rotate. The central shaft 6 inserted into the worm wheel 705 rotates around its own center line, driving the melting furnace body 1 connected to it to rotate. The melting furnace body 1 changes from a vertical state to a downward tilting state. After the melting furnace body 1 tilts downward, it can be aligned with the collection pool 8. The molten glass inside the melting furnace body 1 flows into the collection pool 8 under the action of gravity, completing the molten glass feeding process.

[0036] The lower end of the slag inlet plate 901 is immersed in the molten glass, while the upper end is slightly higher than the height of the molten glass. The recessed hopper 902 is recessed downwards. Driven by the slag scraping drive mechanism 10, the slag inlet plate 901 can move in a direction parallel to the collection tank 8. During the movement, the slag inlet plate 901 pushes the slag on the surface of the molten glass to gather on one side of the direction of travel. The gathered slag is squeezed and lifted into the interior of the recessed hopper 902, where it is stored. The recessed hopper 902 is recessed downwards, and its outer wall is submerged in the molten glass. The slag that enters the recessed hopper 902 will not flow back into the molten glass outside, thus completing the slag collection.

[0037] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
