Description

Technical Field

[0001] This utility model relates to equipment for producing zirconia fiberboard and the field of colloid filament technology, specifically to a spinning reel for manufacturing zirconia fibers. Background Technology

[0002] The information disclosed in the background section of this utility model is intended only to enhance the understanding of the overall background of this utility model, and is not necessarily to be regarded as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0003] Zirconia fiber, as a polycrystalline inorganic refractory fiber, possesses properties such as high temperature resistance (melting point up to 2700℃), oxidation resistance, acid and alkali corrosion resistance, chemical stability, and excellent thermal insulation. It has significant application demands in numerous industries, including aerospace, nuclear energy, metallurgy, and petrochemicals. Currently, common forming processes for preparing zirconia fibers include solution impregnation, solution spinneret pyrolysis, solution electrospinning, colloidal drawing, colloidal spinning, and slurry extrusion. Among these, the colloidal spinning method is widely used due to its high yield, low slag content in the finished product, and relatively low requirements on the properties of the raw materials, making it suitable for large-scale production.

[0004] However, existing wire spinning reels have serious shortcomings in modular design. In actual production, different wire hole diameters often need to be replaced according to different process requirements. However, with the existing wire spinning reel structure, changing the wire hole diameter usually requires remanufacturing the entire reel or replacing it with a completely new one, which is cumbersome and costly. This is because the wire holes and the reel body of existing wire spinning reels are mostly integrated structures, making modular replacement of the wire holes impossible. For example, when it is necessary to adjust the wire hole diameter from 0.5μm to 0.3μm, since the wire hole component cannot be replaced separately, a completely new wire spinning reel with 0.3μm wire holes must be manufactured. This not only wastes a lot of time and material costs but also seriously affects the production schedule.

[0005] Therefore, there is an urgent need for a new spinning disc design to solve the above problems, improve the adaptability of the spinning disc, and reduce the cost of zirconium oxide fiber production. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model proposes a spinning reel for manufacturing zirconia fibers, aiming to solve the issues of difficult replacement, high cost, and poor adaptability of existing spinning reels. Simultaneously, the optimized sealing and connection structure enhances the stability and safety of equipment operation, thereby improving the efficiency and economy of zirconia fiber production.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A spinning reel for manufacturing zirconium oxide fibers includes an inner core and a removably sealed outer cover.

[0009] The inner core is provided with an inner cavity, and an inner core column is provided at the center of the inner cavity. Multiple mounting holes are evenly distributed on the side wall of the inner core. Each mounting hole is provided with a sleeve rod that is fixedly connected to the inner core column. Each sleeve rod can be detachably and sealed with a corresponding spinning ring module. Each spinning ring module has two or more corresponding spinning holes.

[0010] The outer cover has a mounting port at the top center that is sealed to the shaft of the spinning motor, and the mounting port has a feeding channel that communicates with the inner cavity.

[0011] Preferably, the inner wall of the outer cover is connected to the outer wall of the inner cylinder core by a threaded seal, and the side wall of the outer cover is provided with a through hole corresponding to the mounting hole.

[0012] Preferably, the mating surfaces of the outer cover and the inner core are provided with a first sealing gasket.

[0013] Preferably, multiple threaded fasteners are evenly distributed between the outer cover and the inner core, and corresponding fixing holes are provided on the mating surfaces of the outer cover and the inner core, as well as on the sealing gasket.

[0014] Preferably, the wire-spinning ring module and the sleeve rod are connected by a threaded seal.

[0015] Preferably, a limiting ring platform is provided in the mounting hole on the side near the inner wall of the inner cylinder core, and a second sealing gasket is provided on the mating surface of the limiting ring platform and the spinning ring module.

[0016] Preferably, the upper end face of the mounting port is flush with the top surface of the outer cover, and the top of the outer cover is provided with a recessed annular groove around the mounting port, which is used to accommodate the wire spinning motor shaft.

[0017] This utility model has at least the following beneficial effects:

[0018] This invention achieves modular installation of the spinning hole by setting a detachable and sealed spinning ring module. This allows users to quickly replace the spinning ring module with the corresponding specification according to different process requirements (such as changes in fiber diameter); greatly reducing equipment maintenance and adjustment costs; improving production flexibility; and adapting to various product specifications.

[0019] To address the potential risk of relative rotation between the outer cover and the inner core during high-speed rotation, this utility model incorporates a spinning ring module embedded in the through hole of the outer cover and the mounting hole of the inner core, serving as a limiting element. This prevents component misalignment or displacement after assembly, improves the synchronization and stability of the overall structure, and helps enhance the consistency of colloid flow during spinning.

[0020] This invention allows for adjustment of the spinning hole parameters without replacing the entire spinning disc, saving significant material and processing costs; when a module is damaged, only a portion of the component needs to be replaced, avoiding complete scrapping; and it significantly shortens mold changeover time, improving production line response speed.

[0026] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] Figures 1 to 3 A spinning reel for manufacturing zirconia fibers is presented, comprising an inner core 200 and a removably sealed outer cover 100.

[0028] The inner core 200 has an inner cavity, and an inner core column 220 is located at the center of the inner cavity. Multiple mounting holes 210 are evenly distributed on the side wall of the inner core 200. Each mounting hole 210 is provided with a sleeve rod 230 that is fixedly connected to the inner core column 220. Each sleeve rod 230 can be detachably and sealedly connected to a corresponding spinning ring module 400. The sleeve rod 230 provides a foundation for the installation of the spinning ring module 400. At the same time, it enhances the rotational stability in conjunction with the inner core column 220. Each spinning ring module 400 has two or more corresponding spinning holes 410.

[0029] The outer cover 100 has a mounting port 110 at its top center, which is sealed to the shaft of the spinning motor. The mounting port 110 has a feeding channel 120 that communicates with the inner cavity. After the zirconia colloid enters the inner cavity through the feeding channel 120, the spinning disc moves centrifugally under the drive of the spinning motor shaft, thereby generating centrifugal force, which causes the zirconia colloid to be spun out through each spinning hole 410 to form zirconia fibers.

[0030] Because the spinning ring module 400 is detachable, and the diameter and number of spinning holes 410 on the spinning ring module 400 are all of corresponding specifications, different specifications of spinning holes 410 can be replaced by replacing different spinning ring modules 400. This allows products of different specifications to be produced on the same basic equipment, supporting flexible production of multiple varieties and small batches.

[0031] The inner wall of the outer cover 100 is connected to the outer wall of the inner core 200 by a threaded seal. A through hole corresponding to the mounting hole 210 is provided on the side wall of the outer cover 100. The wire-spinning ring module 400 is embedded in the through hole and the mounting hole 210, and can also play a limiting role to prevent relative rotation between the outer cover 100 and the inner core 200, which helps to enhance the stability of their connection.

[0032] To further ensure the sealing between the outer cover 100 and the inner core 200, a first sealing gasket 300 is provided on the mating surfaces of the outer cover 100 and the inner core 200.

[0033] Multiple threaded fasteners 600 are evenly distributed between the outer cover 100 and the inner core 200. Corresponding fixing holes 140 are provided on the mating surfaces of the outer cover 100 and the inner core 200, as well as on the sealing gasket. The fixing holes 140 include both smooth holes and threaded holes. This double-reinforcement structure enhances the overall rigidity and vibration resistance, further improving the stability of the connection between the outer cover 100 and the inner core 200.

[0034] The wire-spinning ring module 400 and the sleeve rod 230 are connected by a threaded seal. In order to ensure the sealing between the wire-spinning ring module 400 and the mounting hole 210, a limiting ring platform 211 is provided in the mounting hole 210 near the inner wall of the inner cylinder core 200, and a second sealing gasket 500 is provided on the mating surface of the limiting ring platform 211 and the wire-spinning ring module 400.

[0035] To reduce the vertical connection distance and improve torsional stability, the wire-spinning motor shaft and the mounting port 110 are embedded. The specific installation structure is as follows: the upper surface of the mounting port 110 is flush with the top surface of the outer cover 100. The top of the outer cover 100 is provided with a recessed annular groove 130 surrounding the mounting port 110, which accommodates the wire-spinning motor shaft. This reduces the vertical connection distance, improves torsional stability, lowers the overall center of gravity, reduces vibration, and improves transmission efficiency and operational smoothness.

[0036] In summary, this utility model not only solves the problems of traditional spinning discs, such as simple structure, inconvenient replacement, and high cost, but also brings a number of technological innovations and practical benefits in terms of structural design, sealing performance, connection stability, energy saving and environmental protection, and has good industrialization prospects and application value.
