Description

Technical Field

[0001] The utility model relates to the technical field of bubbling devices for kilns, in particular to a bubbling device for ultra-fine glass wool kilns. Background Art

[0002] Ultrafine glass wool is a cotton-like inorganic fiber with higher quality among glass fibers. It is widely used in the field of sound absorption and heat insulation due to its good thermal insulation effect. The preparation process of ultrafine glass wool has high technical requirements. Among them, the homogenization quality of the glass liquid directly determines the quality of the produced glass wool. Bubbling technology is a forced homogenization technology for glass liquid. It is an important means to improve the homogenization quality of glass liquid. Its principle is to blow compressed gas into the glass liquid from the bubbling tube at the bottom of the kiln. Bubbles of a certain pressure rise rapidly to the surface of the glass liquid and burst. During the rising process, the bubbles absorb small bubbles in the glass liquid, causing them to grow rapidly and stir the surrounding glass liquid, forcing the homogenization of the glass liquid and promoting clarification.

[0003] The bubbling tubes in ordinary bubbling devices are often made of platinum-rhodium alloy, which is easily corroded by high temperature and has a fast replacement cycle. However, in actual applications of existing bubbling devices for glass liquid processing, the bubbling tubes are fixed to the gas supply system with fastening bolts. If one of the bubbling tubes is blocked or damaged, additional tools are required for disassembly and maintenance, which is inconvenient for staff to disassemble, assemble and replace. This problem restricts the application of bubbling technology in the field of ultra-fine glass wool manufacturing. Utility Model Content

[0025] Example 1

[0026] like Figure 1 and Figure 2As shown, a bubbling device for an ultra-fine glass wool furnace comprises a glass liquid pool 1 and an air supply machine 11 fixedly mounted on one side of the top thereof, a first connecting pipe 12 is fixedly mounted on the gas outlet end of the air supply machine 11, a second connecting pipe 13 connected thereto is fixedly mounted on the end of the first connecting pipe 12, one side of the second connecting pipe 13 is connected to a plurality of fixed conduits 14, a bubbling tube 3 is fixedly mounted on one side of the fixed conduit 14 through a fastening device 2, a bubbling end 31 extending into the interior of the glass liquid pool 1 is formed on one side of the bubbling tube 3, and the fastening device 2 comprises a first ring piece 21, a second ring piece 22, a fixed sleeve 23 and a movable sleeve 24. 4. The outer side of the fixed sleeve 23 and the inner side wall of the movable sleeve 24 are both provided with threads. The outer side of the movable sleeve 24 is provided with anti-slip grooves distributed along its circumferential direction. The first ring piece 21 is fixedly mounted on the end of the fixed conduit 14 away from the second connecting tube 13. The second ring piece 22 is fixedly mounted on the end of the bubbling tube 3 close to the fixed conduit 14 and adapted to the first ring piece 21. The fixed sleeve 23 is fixedly mounted on the outer side of the fixed conduit 14 and fixedly connected to the first ring piece 21. The movable sleeve 24 is movably mounted on the outer side of the bubbling tube 3. Sealing gaskets are fixedly mounted on the opposite sides of the first ring piece 21 and the second ring piece 22.

[0027] Example 2

[0028] like Figure 1 and Figure 3 As shown, an extension tube 5 extending to the inside of the bubbling tube 3 is fixedly installed on the inner wall of the fixed conduit 14 , and an elastic sealing ring 51 fitted with the outer side of the extension tube 5 is fixedly installed on the inner wall of the bubbling tube 3 .

[0029] Specifically, since the extension tube 5 extends into the bubbling tube 3 , the gas pressure between the first ring piece 21 and the second ring piece 22 is reduced, and the elastic sealing ring 51 is squeezed on the outside of the extension tube 5 to further isolate the gas between the first ring piece 21 and the second ring piece 22 .

[0030] like Figure 3 As shown, the extension tube 5 is of conical design, and the inner ring shape of the sealing ring 51 is adapted to the outer side of the extension tube 5.

[0031] Specifically, the gas pressure on the right side of the sealing ring 51 causes it to deform toward the fixed conduit 14. Since the surface of the extension tube 5 is conically inclined, it provides support for the inner ring of the sealing ring 51, so that the sealing ring 51 can fit the extension tube 5 more effectively for sealing, and further isolate the gas between the first ring piece 21 and the second ring piece 22.

[0032] like Figure 1 and Figure 4As shown: a limiting component 4 is fixedly installed on the top of the glass liquid pool 1 and is sleeved on the outside of the bubbling tube 3. The limiting component 4 includes a first U-shaped limiting block 41 and a second U-shaped limiting block 42 that fit together. The second U-shaped limiting block 42 is fixedly installed on the top of the glass liquid pool 1. A placement groove 411 is provided on both sides of the bottom end of the first U-shaped limiting block 41. A first magnet 412 is fixedly installed on the inner wall of the placement groove 411. A second magnet 413 is fixedly installed on both sides of the top end of the second U-shaped limiting block 42, extending into the inside of the placement groove 411 and engaging with the first magnet 412. Sponge pads are fixedly installed on the inner walls of the first U-shaped limiting block 41 and the second U-shaped limiting block 42.

[0033] Specifically, the first U-shaped limit block 41 and the second U-shaped limit block 42 are sleeved on the outside of the bubbling tube 3 and the first magnet 412 and the second magnet 413 are attracted to limit the position of the bubbling tube 3 to prevent the bubbling tube 3 from shifting when the gas is bubbling and affecting its pipeline connection, thereby improving stability.

[0034] Principle of use: The gas supply machine 11 blows the bubbling gas into the interior of the fixed conduit 14 through the first connecting tube 12 and the second connecting tube 13, and discharges the gas from the bubbling end 31 through the bubbling tube 3 connected to the fixed conduit 14 to achieve bubbling of the glass liquid; the first U-shaped limit block 41 and the second U-shaped limit block 42 are sleeved on the outside of the bubbling tube 3 and the position of the bubbling tube 3 is limited by the attraction of the first magnet 412 and the second magnet 413 to prevent the bubbling tube 3 from deviating when the gas is blown out and affecting its pipeline connection, thereby improving stability; when it is needed after long-term use When repairing the bubbling tube 3, rotate the movable sleeve 24 to loosen it from the fixed sleeve 23. At the same time, the clamping force between the first ring piece 21 and the second ring piece 22 disappears until the movable sleeve 24 is separated from the fixed sleeve 23. The bubbling tube 3 can be removed to facilitate user maintenance. Then a new bubbling tube 3 can be docked with the fixed guide tube 14, the first ring piece 21 and the second ring piece 22 are fitted, and the movable sleeve 24 is rotated in the opposite direction to continue to tighten it with the fixed sleeve 23. The movable sleeve 24 applies a thrust to the second ring piece 22 perpendicular to its inner side wall in the length direction, so that the bubbling tube 3 can be removed. The second ring piece 22 is fixed to the first ring piece 21, and the sealing gasket that fits each other between the first ring piece 21 and the second ring piece 22 ensures the sealing of the connection between the bubbling tube 3 and the fixed conduit 14, so that the bubbling tube can be installed without tools, thereby improving practicality. When the fixed conduit 14 is provided with an extension tube 5 and the bubbling tube 3 is provided with an elastic sealing ring 51, the extension tube 5 extends into the bubbling tube 3, thereby reducing the gas pressure between the first ring piece 21 and the second ring piece 22, and the elastic sealing ring 51 is squeezed on the outside of the extension tube 5, further isolating the first ring piece When the extension tube 5 is conical in design, the gas between the first ring piece 21 and the second ring piece 22 is strengthened, thereby enhancing the sealing and stability of the connection between the bubbling tube 3 and the fixed conduit 14; when the extension tube 5 is conical in design, the gas pressure on the right side of the sealing ring 51 causes it to deform toward the fixed conduit 14. Since the surface of the extension tube 5 is conical and inclined, it provides support for the inner circle of the sealing ring 51, so that the sealing ring 51 can be more effectively fitted with the extension tube 5 for sealing, further isolating the gas between the first ring piece 21 and the second ring piece 22, thereby enhancing the sealing and stability of the connection between the bubbling tube 3 and the fixed conduit 14.

[0035] It's important to note that when selecting and preparing treatment solutions, it's important to choose one that reacts chemically with the pollutants in the exhaust gas, based on their type and properties. Common solutions include acids, bases, oxidizing agents, and reducing agents. The selected solutions are then mixed into an absorption solution in a specific ratio to ensure sufficient absorption capacity and stability.

[0036] The foregoing description is merely a detailed description of specific embodiments of the present invention, intended to enable those skilled in the art to understand and implement the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
