Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of fiber-forming devices, and in particular relates to a novel aluminum oxide fiber-forming device with stable fiber formation. Background Art
[0002] Alumina fiber is a polycrystalline inorganic fiber whose main component is alumina. It has excellent properties such as high temperature resistance, low thermal conductivity and high compressive strength.
[0003] The spinning device plays a crucial role in the process of converting existing alumina fiber sol into fiber products. During spinning, the spinning holes on the spinning disk are arranged in parallel rows. This causes the fibers to be spun out in a manner such that the fibers spun out from the top spinning hole block the fibers spun out from the lower spinning holes. Consequently, the traction air from the traction air ring cannot reach all the spun fibers. Since the spun fibers need to undergo secondary fibrillation by the traction air, this can cause the fibers that are not blown out to bend and become stranded, resulting in unstable fiber output and unstable fiber quality. Utility Model Content
[0004] The purpose of the present invention is to address the deficiencies of the prior art and provide a new alumina fiber fiberizing device with stable fiberizing, so as to solve the technical problem in the prior art that the traction wind cannot blow all the fiber filaments that are thrown out, resulting in bending and winding of the fiber filaments that are not blown out, resulting in unstable fiberization of the thrown fiber filaments and unstable fiber quality.

[0014] 2.

[0019] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] like Figure 1-Figure 2 As shown, a new type of alumina fiber fiberizing device with stable fiberizing performance includes a cotton collecting cover 1, a hollow rotating shaft 2, a wire-spinning disk 3, a driving assembly 4 and a traction air ring 5. The device also includes: a plurality of groups of wire-spinning holes 31 are opened on the periphery of the wire-spinning disk 3, and each group of wire-spinning holes 31 is arranged at an angle.
[0021] In one case of this embodiment, the driving assembly 4 includes a motor, a pulley, and a transmission belt. The motor drives the hollow shaft 2 to rotate through the transmission of the pulley and the transmission belt.
[0022] When this embodiment is actually used, fiber sol is added into the hollow rotating shaft 2, so that the fiber sol enters the spinning disk 3 along the hollow rotating shaft 2. At this time, the hollow rotating shaft 2 is rotated by the driving component 4, and the hollow rotating shaft 2 drives the spinning disk 3 to rotate, so that the fiber sol is centrifugally thrown out from the several spinning holes 31 on the periphery of the high-speed rotating spinning disk 3, and then undergoes secondary fibrillation under the action of the traction wind blown by the traction wind ring 5. Finally, it is quickly dried into fiber filaments in the cotton collecting hood 1 with certain humidity and temperature. Since each group of spinning holes 31 is in an inclined state, the fiber filaments thrown out from each group of spinning holes 31 will also be arranged in an inclined state, so that the upper fiber filaments will not block the lower fiber filaments, thereby effectively avoiding the bending and winding of the fiber filaments, making the fiber output stable, thereby ensuring the stable quality of the fiber filaments.
[0023] Furthermore, the distance between the downward projections of two adjacent wire-spinning holes 31 is greater than the diameter of one wire-spinning hole 31 .
[0024] In actual application of this embodiment, the swung out fiber filaments are arranged at intervals, so that the traction wind can blow to all the fiber filaments, thereby making the swung out fiber filaments stable, thereby ensuring the stable quality of the fiber filaments.
[0025] Furthermore, an annular guide plate 6 is provided on the traction air ring 5 . The guide plate 6 is tilted downward, and its tilting direction is toward the wire-spinning hole 31 .
[0026] In actual application of this embodiment, the traction wind can be guided to the position where the fiber filaments are thrown out through the guide plate 6, so that the traction wind can blow the fiber filaments at the first time. This can effectively avoid the traction wind blowing direction being messy, which causes the fiber filaments to take a long time to be blown by the traction wind, thereby making the thrown fiber filaments stable, thereby ensuring the stable quality of the fiber filaments.
[0027] Furthermore, a guide platform 7 is provided at the bottom of the inner cavity of the cotton collecting hood 1 , the top of the guide platform 7 is in the shape of a truncated cone, and a plurality of exhaust holes 8 are evenly opened on the periphery of the cotton collecting hood 1 .
[0028] During actual application of this embodiment, after the traction wind is guided by the guide plate 6, the traction wind is blocked by the guide platform 7. After being blocked by the guide platform 7, the traction wind is discharged through the exhaust hole 8. In this way, on the one hand, it can effectively prevent the traction wind from rebounding after blowing to the bottom of the inner cavity of the cotton collecting hood 1, causing the direction of the traction wind to be messy, thereby affecting the stability of the fiber output. On the other hand, discharging the traction wind can effectively control the temperature in the cotton collecting hood 1, thereby effectively preventing the fiber sol in the spinning disk 3 from being dehydrated and condensed due to high temperature, causing the spinning hole 31 to be blocked, thereby reducing the fiber forming efficiency.
[0029] like Figure 2 As shown, a pendulum 9 is rotatably installed at the center position of the spinning disc 3.
[0030] In one case of this embodiment, there is a certain gap between the pendulum 9 and the inner wall of the spinning disk 3, which makes it convenient for the pendulum 9 to squeeze the fiber sol through the spinning hole 31; in addition, the pendulum 9 has a certain weight, so that the rotation speed of the pendulum 9 is always greater than the rotation speed of the spinning disk 3.
[0031] In actual application of this embodiment, after the spinning disk 3 rotates, the pendulum 9 also slowly rotates until the rotation speed of the pendulum 9 is greater than the rotation speed of the spinning disk 3. At this time, the pendulum 9 will squeeze the fiber sol in the spinning disk 3 and squeeze the fiber sol out through the spinning hole 31. During each squeezing, since the distance between the pendulum 9 and the inner wall of the spinning disk 3 is fixed, the amount of fiber sol squeezed each time is the same, so that each fiber filament thrown out is uniform in size, thereby improving the stability of fiber formation.
[0032] like Figure 2 As shown, a spiral disk 21 is provided in the hollow shaft 2 .
[0033] In actual application of this embodiment, the spiral disk 21 can reduce the speed of the fiber sol flowing downward, thereby avoiding excessive amount of fiber sol in the spinning disk 3, resulting in uneven fiber output from the spinning hole 31, thereby further improving the stability of fiber formation.
[0034] Working principle: When in use, by adding fiber sol into the hollow rotating shaft 2, the fiber sol enters the spinning disk 3 along the hollow rotating shaft 2, and then the hollow rotating shaft 2 is rotated by the driving component 4, and the hollow rotating shaft 2 drives the spinning disk 3 to rotate, so that the fiber sol is centrifugally thrown out from the several spinning holes 31 on the periphery of the high-speed rotating spinning disk 3, and then undergoes secondary fibrillation under the action of the traction wind blown by the traction wind ring 5, and finally is quickly dried into fiber filaments in the cotton collecting hood 1 with certain humidity and temperature.
[0035] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
