Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrospinning technology, and in particular to an alumina fiber spinning device. Background Technology
[0002] Electrospinning is a simple and effective processing technology for producing nanofibers, playing a significant role in fields such as biomedical materials, filtration and protection, catalysis, energy, optoelectronics, food engineering, and cosmetics. It involves jet spinning of a polymer solution or melt within a strong electric field. Under the influence of the electric field, the droplet at the needle changes from a spherical shape to a conical shape, and then extends from the tip of the cone to form fine filaments.
[0003] In the electrospinning production of alumina fibers, the spun preform, due to electrostatic effects, is subjected to an upward electrostatic force, making it difficult to fall off and prone to snagging near the spinning nozzle, thus affecting the quality of the fiber product. Currently, in actual production, the spinning box generally uses air suction and air blowing to separate the spun preform, resulting in significant energy waste during the spinning process and unsatisfactory fiber product quality. Therefore, this paper proposes an alumina fiber spinning device to address the aforementioned problems. Utility Model Content
[0004] The purpose of this invention is to provide an alumina fiber spinning device that solves the technical problems of existing spinning boxes using air suction and blowing to separate the spinning blank, resulting in serious energy waste during the spinning process and unsatisfactory fiber product quality.
[0005] To achieve the above objectives, this utility model provides an alumina fiber spinning device, comprising:
[0006] Box;

[0019] Compared with the above-mentioned background technology, the alumina fiber spinning equipment provided by this utility model has the following beneficial effects:
[0020] (1) In this utility model, the exhaust fan delivers high-temperature drying airflow to the upper part of the box through the air supply pipe, and at the same time extracts the waste gas through the exhaust pipe. A directional forming airflow is formed inside the box. The forming airflow quickly conveys the fiber blank to the conveyor network while drying the fiber blank, effectively improving the filament hanging situation at the spinning nozzle position and improving the quality of fiber products.
[0021] (2) This utility model sets a drying, filtering and heating device at the exhaust port of the exhaust fan to treat the exhaust gas extracted by the exhaust pipe, filter out and remove the floating blanks, and then the purified high-temperature dry airflow is transported to the air supply head through the air supply pipe. Finally, the high-temperature dry airflow is evenly delivered to the inside of the spinning box through the air supply head, which further improves the filament hanging situation at the spinning nozzle position and improves the quality of fiber products.

[0026] 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.
[0027] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0028] like Figure 1 and Figure 2 As shown, in order to achieve the above objectives, this utility model provides an alumina fiber spinning device, including: a housing 1 and a plurality of spinning nozzles (not shown in the figure) disposed on the housing 1. Specifically, the plurality of spinning nozzles are arranged in an array on the upper part of the housing 1, and the spinning nozzles are used to spray out fiber preforms.
[0029] It should be noted that an exhaust fan 2 is installed on the outside of the housing 1. The air inlet of the exhaust fan 2 is connected to an exhaust pipe 3. The lower end of the exhaust pipe 3 is located on the inside of the housing 1. The exhaust fan 2 extracts the gas from the lower part of the housing 1 through the exhaust pipe 3.
[0030] In one embodiment of this utility model, a drying and filtering heating device 4 is installed at the exhaust port of the exhaust fan 2. The drying and filtering device is used to heat the gas drawn by the exhaust pipe 3. At the same time, the drying and filtering device can treat the exhaust gas drawn out by the exhaust pipe 3, filter out and remove the floating blanks, purify the high-temperature drying airflow, and further improve the filament hanging situation at the spinning nozzle position. The drying and filtering heating device 4 is connected to the air supply pipe 5, and the air supply pipe 5 is connected to the air supply head 6. The air supply head 6 is located directly above the box 1. The heated gas is transported through the air supply pipe 5 to the upper part of the inner side of the box 1 to dry and separate the fiber blanks sprayed out by the spinning nozzle.
[0031] In operation, multiple spinning nozzles eject fiber preforms. The exhaust fan 2 delivers high-temperature drying airflow to the upper part of the housing 1 via the air supply pipe 5, while simultaneously extracting waste gas through the exhaust pipe 3. A directional forming airflow is formed inside the housing 1. This forming airflow dries the fiber preforms as it blows them away from the spinning nozzles and downwards, improving fiber adhesion at the spinning nozzle location and enhancing fiber product quality. Furthermore, the drying and filtering device heats the waste gas extracted through the exhaust pipe 3 and filters out any floating preforms. The high-temperature drying airflow is then delivered to the air supply head 6 via the air supply pipe 5. Finally, the air supply head 6 evenly distributes the high-temperature drying airflow inside the spinning housing 1, forming a gas circulation. Since the waste gas inside the housing 1 has a certain temperature, the drying, filtering, and heating device 4 does not require high power, effectively reducing energy consumption during production.
[0032] In one embodiment of this utility model, a drying chamber is provided in the middle part of the box 1. The drying chamber is integrally formed in the box 1 and connects the upper and lower parts of the box 1. The drying chamber is used to provide a drying environment for the fiber blank forming. During the process of the forming airflow blowing the fiber blank downward, the drying chamber can extend the drying time of the forming airflow on the fiber blank, improve the drying effect on the fiber blank, and thus improve the quality of the fiber product.
[0033] It should be noted that the air supply head 6 is cone-shaped, and the diameter of the bottom end of the air supply head 6 is larger than the diameter of the top end of the air supply head 6. The shape of the air supply head 6 can be compared with a horn. Its function is to increase the air supply area of the air supply head 6. In addition, the diameter of the bottom end of the air supply head 6 is larger than the diameter of the upper part of the housing 1, which can ensure that each fiber nozzle can receive the high-temperature dry airflow delivered by the air supply head 6.
[0034] Preferably, a flow divider 7 is provided at the bottom of the air outlet 6. The flow divider 7 is used to evenly distribute the high-temperature drying airflow. Specifically, the surface of the flow divider 7 is arrayed with several through holes of the same size, thereby evenly delivering the high-temperature drying airflow into the drying chamber. Of course, the air outlet can also be designed as a grid, which can also evenly deliver the high-temperature drying airflow into the drying chamber.
[0035] It should be noted that a conveyor net 8 is provided at the lower part of the housing 1, which is used to receive the fiber preform. Specifically, two drive rollers are rotatably connected to the inner side of the housing 1, and the conveyor net 8 is sleeved on the outer circumferential side of the two drive rollers. A drive motor is provided on one side of the housing 1. Preferably, the drive motor is a servo motor. The output end of the drive motor is connected to one of the drive rollers. The drive motor drives one of the drive rollers to rotate, thereby driving the conveyor net 8 to operate. The forming airflow blows the fiber preform away from the spinning nozzle and blows it downward to the conveyor net 8, which then conveys it to the next processing step.
[0036] The conveyor network 8 is located above the exhaust pipe 3 to ensure that when the exhaust pipe 3 is drawing exhaust gas from the lower part of the box 1, the exhaust pipe 3 will not block the fiber material from being blown downward by the forming airflow to the conveyor network 8, and the fiber material can always be received by the conveyor network 8.
[0037] In one embodiment of this utility model, the top end of the air supply head 6 is sleeved at the bottom end of the exhaust pipe 3, and the top end of the air supply head 6 is slidably connected to the bottom end of the exhaust pipe 3. The position of the air supply head 6 relative to the exhaust pipe 3 can be flexibly adjusted according to the requirements, that is, the height of the air supply head 6 has a certain adjustment space to ensure that the air supply head 6 and the upper part of the housing 1 maintain the best air supply distance.
[0038] A locking sleeve 9 is fitted onto the outer wall of the air supply head 6. The locking sleeve 9 is fitted onto the upper end of the air supply head 6 and is used to lock the position of the air supply head 6 on the exhaust pipe 3. Specifically, the locking sleeve 9 includes a locking ring. The two ends of the locking ring are connected by fastening bolts. By turning the fastening bolts counterclockwise, the locking ring loosens the upper end of the air supply head 6. At this time, the air supply head 6 can move up and down a certain height relative to the exhaust pipe 3. After adjusting the distance between the air supply head 6 and the upper part of the housing 1, the fastening bolts are turned clockwise, and the locking ring locks the upper end of the air supply head 6. At this time, the air supply head 6 is fixedly connected to the exhaust pipe 3, and the position of the air supply head 6 is fixed.
[0039] In one embodiment of this utility model, an observation window 10 is provided on the side of the box 1, which allows observation of the fiber fragment formation inside the box 1. In case of any unexpected situation, the machine can be stopped for maintenance at any time. At the same time, the observation window 10 can clearly show whether there is too much fiber fragment adhering to the inner wall of the box 1 and it needs to be cleaned. Moreover, the parameters of the overall equipment can be adjusted according to the fiber fragment formation inside the box 1 to improve the quality of fiber products.
[0040] In one embodiment of this utility model, a temperature sensor (not shown in the figure) is provided at the exhaust port of the exhaust fan 2. The temperature sensor detects the temperature of the exhaust gas in real time, and the power of the drying and heating device can be precisely adjusted according to the temperature of the exhaust gas, thereby ensuring that the drying and heating device can output a more stable high-temperature drying airflow, resulting in more stable fiber body formation and further improving the quality of fiber products.
[0041] In use, multiple spinning nozzles eject fiber preforms. The exhaust fan 2 delivers air to the upper part of the housing 1 through the air supply pipe 5, and simultaneously draws air from the lower part of the housing 1 through the exhaust pipe 3. The drying and filtering device heats the exhaust gas drawn out by the exhaust pipe 3 and filters out the floating preforms. The high-temperature drying airflow is then delivered to the air supply head 6 through the air supply pipe 5. Finally, the high-temperature drying airflow is evenly delivered into the spinning housing 1 through the air supply head 6. A directional forming airflow is formed inside the housing 1. The forming airflow blows the fiber preforms away from the spinning nozzles and quickly conveys them to the conveyor network 8. The forming airflow dries the blown fibers while blowing the fiber preforms. The conveyor network 8 conveys the dried fiber preforms to the next processing step.
[0042] In summary, the exhaust fan 2 delivers the high-temperature drying airflow to the upper part of the housing 1 through the air supply pipe 5, and at the same time extracts the exhaust gas through the exhaust pipe 3. A directional forming airflow is formed inside the housing 1, which dries the fiber preform. Meanwhile, the drying filter heating device 4 filters out the preform floating in the exhaust gas with a certain temperature. The high-temperature drying airflow is heated and purified at the same time, which improves the filament hanging situation at the spinning nozzle and improves the quality of fiber products.
