Description

Technical Field

[0001] This utility model belongs to the technical field of fiber spinning equipment, and in particular relates to a novel alumina fiber spinning device that prevents clogging. Background Technology

[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] In the process of transforming alumina fiber sol into fiber products, the spinning device plays a crucial role. During operation, the spinning disc in existing spinning devices is affected by the temperature inside the cotton collection hood, resulting in a high internal temperature. This can cause the fiber sol to evaporate moisture and solidify, easily clogging the spinning holes and reducing fiber formation efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a novel anti-clogging alumina fiber spinning device, thereby solving the technical problem that fiber sol easily coagulates and clogs the spinning holes in existing technologies.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A novel anti-clogging alumina fiber spinning device includes a cotton collection cover, a hollow rotating shaft, a spinning disc, spinning holes, a drive assembly, and a traction air ring. The device further includes:

[0007] A guide table is provided at the center of the spinning disc, and a flow space for the fiber sol to pass through is reserved between the guide table and the bottom end of the hollow rotating shaft.

[0008] The guide table and the spinning disc form a flow cavity, and the ball bearings are placed in the flow cavity.

[0009] As a preferred embodiment of the above technical solution, the size of the ball is larger than the size of the flow space reserved between the guide table and the bottom end of the hollow rotating shaft.

[0010] As a preferred embodiment of the above technical solution, the top of the guide platform is conical.

[0011] As a preferred embodiment of the above technical solution, the spinning reel is covered with a heat insulation cover.

[0012] As a preferred embodiment of the above technical solution, cooling plates are provided at both the top and bottom of the heat insulation cover.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. In this utility model, the fiber sol is kept in a flowing state by the rotating and rolling of the ball in the flow chamber, so that the fiber sol is not easy to coagulate and the spinning hole is not easy to be blocked, thus improving the fiber forming efficiency.

[0015] 2. In this utility model, the heat insulation cover and cooling plate can effectively prevent the temperature of the fiber sol from rising, effectively prevent the loss of moisture from the fiber sol by evaporation, and prevent the fiber sol from condensing and dehydrating to form solid particles that block the spinning holes.

[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1-2 As shown, a novel anti-clogging alumina fiber spinning device includes a cotton collection cover 1, a hollow rotating shaft 2, a spinning disc 3, a spinning hole 31, a drive assembly 4, and a traction air ring 5. The device also includes:

[0022] The guide table 6 is located at the center of the spinning disc 3. A flow space for the fiber sol to pass through is reserved between the guide table 6 and the bottom of the hollow rotating shaft 2.

[0023] The ball bearing 7, the guide table 6 and the spinning disc 3 form a flow cavity 8, and the ball bearing 7 is placed in the flow cavity 8.

[0024] In one embodiment, the drive assembly 4 consists of a motor, a pulley, and a transmission belt. Through the transmission of the pulley and the transmission belt, the motor drives the hollow shaft 2 to rotate.

[0025] In practical application, this embodiment involves adding fiber sol into the hollow rotating shaft 2, allowing the fiber sol to flow along the hollow rotating shaft 2 into the spinning disc 3. The fiber sol then enters the flow cavity 8 through the flow space reserved between the guide platform 6 and the bottom end of the hollow rotating shaft 2. At this time, the drive assembly 4 rotates the hollow rotating shaft 2, which in turn drives the spinning disc 3 to rotate. Due to centrifugal force, the balls 7 inside the spinning disc 3 continuously rotate and roll along the flow cavity 8, keeping the fiber sol in the flow cavity 8 in a state of constant flow. In the process, the fiber sol is centrifugally ejected from several spinning holes 31 around the high-speed rotating spinning disc 3, which prevents the fiber sol from condensing and the spinning holes 31 from clogging. Then, under the action of the traction air blown out by the traction air ring 5, it undergoes secondary fine fiberization. Finally, it is rapidly dried into fiber filaments in the cotton collection cover 1 with constant humidity and temperature. The fiber sol is kept in a flowing state by the rotating and rolling of the ball bearing 7 in the flow chamber 8, which prevents the fiber sol from condensing and the spinning holes 31 from clogging, thus improving the fiber forming efficiency.

[0026] Furthermore, the size of the ball 7 is larger than the size of the flow space reserved between the guide table 6 and the bottom of the hollow rotating shaft 2.

[0027] In practical applications, due to the large size of the ball bearing 7, it is not easy for the ball bearing 7 to get stuck in the flow space reserved between the guide table 6 and the bottom of the hollow rotating shaft 2 when it rotates and rolls. This ensures that the fiber sol in the flow cavity 8 is always in a flowing state, effectively preventing the fiber sol from condensing and blocking the spinning hole 31.

[0028] Furthermore, the top of the guide platform 6 is conical.

[0029] In practical applications, the conical shape at the top of the guide platform 6 facilitates the flow of fiber sol into the flow cavity 8, thus guiding the flow and preventing the fiber sol from clogging the bottom of the hollow rotating shaft 2.

[0030] like Figure 1 and Figure 2 As shown, the spinning reel 3 is covered with a heat insulation cover 9.

[0031] In one embodiment, the heat insulation cover 9 is a heat insulation material, such as thermal insulation cotton. The heat insulation cover 9 has through holes 91, which allow several spinning holes 31 to be exposed.

[0032] In practical application, the heat insulation cover 9 isolates the heat inside the cotton collection cover 1, effectively preventing the fiber sol from being affected by external heat and causing its own temperature to rise, preventing the fiber sol from evaporating and losing moisture, and preventing the fiber sol from condensing and dehydrating to form solid particles that block the spinning hole 31.

[0033] Furthermore, cooling plates 10 are provided at both the top and bottom of the heat insulation cover 9.

[0034] In practical applications of this embodiment, the cooling element 10 is existing technology and will not be described in detail here. The cooling element 10 can reduce the temperature around the spinning disc 3, thereby effectively preventing the temperature of the fiber sol in the spinning disc 3 from rising and preventing the fiber from dissolving and condensing to block the spinning hole 31.

[0035] Working principle: During use, fiber sol is added to the hollow rotating shaft 2, allowing it to enter the spinning disc 3 along the shaft. The fiber sol then enters the flow chamber 8 through the flow space reserved between the guide table 6 and the bottom of the hollow rotating shaft 2. At this time, the drive assembly 4 rotates the hollow rotating shaft 2, which in turn drives the spinning disc 3 to rotate. Due to centrifugal force, the balls 7 inside the spinning disc 3 rotate and roll along the flow chamber 8, keeping the fiber sol in the flow chamber 8 in a continuous flow state. The fiber sol is centrifugally ejected from several spinning holes 31 around the high-speed rotating spinning disc 3, thus preventing the fiber sol from condensing and the spinning holes 31 from clogging. Under the action of the traction air blown by the traction air ring 5, it undergoes secondary refining and finally dries rapidly into fiber filaments in the cotton collection cover 1 with constant humidity and temperature.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
