The high-temperature hot gas is directly discharged, causing the heat that could have been used for auxiliary heating to be wasted, increasing the energy consumption of the melting process and raising production costs. Therefore, a melting device for glass processing is proposed. Summary of the Invention

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 The glass processing melting device in this embodiment includes a melting device body 1. The inside of the melting device body 1 is arranged from top to bottom as a crushing zone 2 and a melting zone 3. A heat recovery mechanism 4 is arranged on the right side of the melting device body 1.

[0025] The heat recovery mechanism 4 includes a fan 401, a cyclone separator 402 at the bottom of the fan 401, a bag filter 403 at the bottom of the cyclone separator 402, a heat exchanger 404 at the bottom of the bag filter 403, an air intake pipe 405 connecting the input end of the fan 401 to the smelting zone 3, an air delivery pipe 406 connecting the output end of the fan 401 to the cyclone separator 402, a processing pipe 407 connecting the cyclone separator 402 and the bag filter 403, and an installation pipe 408 connecting the bag filter 403 and the heat exchanger 404.

[0026] The function of the blower 401 is to provide power and draw in the high-temperature hot gas generated in the smelting zone 3 through the suction pipe 405. Its principle is to use the rotation of the impeller inside the blower 401 to create a directional flow of gas. A cyclone separator 402 is installed at the bottom of the blower 401. The cyclone separator 402 uses centrifugal force to separate larger particles of impurities from the high-temperature hot gas. Through centrifugal force, heavier impurities are thrown against the inner wall of the separator 402 and then slide down to the bottom for discharge, reducing the processing burden on subsequent equipment and improving heat recovery efficiency. A bag filter 403 is installed at the bottom of the cyclone separator 402. The bag filter 403 uses filtration to intercept fine dust and other impurities that are not completely separated by the cyclone separator 402. Through the microporous structure of the filter bag, gas passes through while impurities remain on the surface of the bag, further purifying the high-temperature hot gas. To ensure the purity of subsequent heat recovery, a heat exchanger 404 is installed at the bottom of the bag filter 403. The heat exchanger 404 is the core component of heat recovery. It transfers the heat of the purified high-temperature hot gas to other media such as air and water through the principle of heat exchange. An air suction pipe 405 is connected between the input end of the fan 401 and the smelting zone 3 to transport high-temperature hot gas. An air delivery pipe 406 is connected between the output end of the fan 401 and the cyclone separator 402 to transport the high-temperature hot gas sucked in by the fan 401 to the cyclone separator 402. A treatment pipe 407 is installed between the cyclone separator 402 and the bag filter 403 to transport the high-temperature hot gas that has been preliminarily treated by the cyclone separator. An installation pipe 408 is installed between the bag filter 403 and the heat exchanger 404 to transport the purified high-temperature hot gas to the heat exchanger 404.

[0027] A burner 411 is installed inside the bottom of the melting device body 1. The burner 411 is a device that provides heat to the melting zone 3. It generates high-temperature flames and hot gas by burning fuel, and transfers the heat to the melting zone 3 through the heat supply pipe, so that the glass raw material reaches a molten state. A connecting pipe 409 is provided between the heat exchanger 404 and the burner 411. The connecting pipe 409 transfers the heat recovered by the heat exchanger 404 to the burner 411. The burner 411 uses the recovered heat to preheat the fuel, reducing the energy required for the fuel to reach the combustion temperature, thereby reducing energy consumption and production costs. An auxiliary pipe 410 is provided on the right side of the heat exchanger 404. Valves are provided on both the connecting pipe 409 and the auxiliary pipe 410. The auxiliary pipe 410 can be connected to other equipment that requires heat. By controlling the valves on the connecting pipe 409 and the auxiliary pipe 410, the recovered heat can be flexibly distributed, improving the heat utilization rate.

[0028] By setting two crushing rollers 501 in the crushing zone 2, the two crushing rollers 501 rotate in opposite directions through two meshing circular gears 503 on their surfaces, crushing the glass raw material into smaller particles by squeezing and grinding, which facilitates subsequent melting in the melting zone 3 and improves melting efficiency. A fixing plate 502 is fixedly installed on the left side of the melting device body 1. The fixing plate 502 is used to support and fix the crushing rollers 501 and the motor 504 and other components to ensure the stability of the equipment operation.

[0029] By setting a stirring rod 506 in the melting zone 3, the stirring rod 506 rotates under the drive of the motor 504 to stir the glass raw materials in the melting zone 3, so that the raw materials are heated more evenly, avoiding local overheating or undercooling, and improving the quality of glass products.

[0030] The feed inlet 6 facilitates the entry of glass raw materials into the crushing zone 2. After crushing, the glass raw materials enter the melting zone 3 through the connection port. After melting, the molten glass is discharged from the discharge port 7.

[0031] In actual use, glass raw materials enter the crushing zone 2 through the feed port 6. The motor 504 drives the crushing roller 501 to rotate, crushing the raw materials and sending them into the melting zone 3. Then, the burner 411 is started to provide heat. At the same time, the stirring rod 506 is driven by another motor 504 to stir the raw materials, so that they are heated evenly. During the melting process, the blower 401 draws high-temperature hot air from the melting zone 3 through the suction pipe 405, and purifies it in sequence through the cyclone separator 402 and the bag filter 403. Then, the heat is recovered in the heat exchanger 404. The recovered heat is transported to the burner 411 through the connecting pipe 409 to preheat the fuel to reduce energy consumption. If necessary, the heat can also be distributed through the auxiliary pipe 410. After the raw materials are completely melted, the glass liquid is discharged from the discharge port 7, completing the melting process.

[0032] In summary, this glass processing melting apparatus, by setting up a heat recovery mechanism 4, uses a fan 401 to purify the high-temperature hot gas generated in the melting zone 3 through a cyclone separator 402 and a bag filter 403, recovers the heat in the heat exchanger 404, and transfers the heat to the burner 411 through a connecting pipe 409. This achieves the recovery and utilization of waste heat in the high-temperature hot gas, reduces energy consumption, and lowers production costs.

[0033] Furthermore, by setting up a crushing roller 501 in the crushing zone 2 and a stirring rod 506 in the melting zone 3, the crushing roller 501 crushes the glass raw material, making it easier to melt; the stirring rod 506 ensures that the glass raw material is heated evenly in the melting zone 3, improving the quality of the glass product. At the same time, in conjunction with the heat recovery mechanism 4, it further enhances the overall efficiency and economic benefits of glass processing.
