Description

TECHNICAL FIELD

[0001] The utility model relates to centrifugal cotton production equipment technical field, specifically, relate to a kind of centrifugal disc and equipment for centrifugal cotton production. BACKGROUND

[0002] In the centrifugal cotton production process, the centrifuge is one of the key equipment, which usually includes an annular flame port and a centrifugal disc arranged below the flame port. The annular flame port is composed of an inner flame ring and an outer flame ring, that is, an annular flame passage composed of an inner flame ring wall and an outer flame ring wall, for downwardly injecting high-speed flame; the centrifugal disc is installed on the rotating main shaft, and in the high-speed rotation process, the high-temperature glass liquid entering the disc is thrown out through the small holes densely distributed on the peripheral side wall to form glass liquid strands, and is stretched into fibers under the traction of the outer flame generated by the annular flame port. In order to maintain the temperature of the glass liquid in the centrifugal disc, an inner combustion head is usually arranged in the disc to ensure the temperature of the glass liquid in the disc, and the flue gas generated by the combustion forms a positive pressure inside the centrifugal disc.

[0003] However, the outer diameter of the centrifugal disc in the conventional centrifugal cotton production equipment is generally the same as the diameter of the inner flame ring. In actual operation, the outer diameter of the centrifugal disc increases after being heated, causing the high-speed flame to directly impact the upper edge of the centrifugal disc and rebound and diffuse into the disc, which hinders the smooth exhaust of the internal flue gas, resulting in a relatively high positive pressure environment in the disc. This positive pressure forces the flue gas to escape upward from the feed port, causing strong disturbance to the continuously falling glass liquid strands, resulting in swinging of the strands, easy adhesion to the discharge port and even blockage, which seriously affects the continuity and running stability of the production.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

In the present specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or implementation. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or implementations in a suitable manner.

[0029] To solve the above technical problems, as Figures 1 to 4 The embodiment of the present application provides a centrifugal disc for centrifugal cotton production, which is a disc-shaped structure as a whole, comprising a disc bottom 10 and a disc wall 20 connected together, wherein the disc bottom 10 is horizontally arranged, and the center of the disc bottom 10 is used to be connected with a rotating main shaft 02; the disc wall 20 is vertically arranged at the edge of the disc bottom 10, a plurality of through holes 21 are arranged on the disc wall 20 in the horizontal direction, the through holes 21 are used for the glass liquid 03 to pass through, and the outer corner of the upper end of the disc wall 20 is provided with a chamfer structure 30, and the outer diameter of the disc wall 20 is smaller than the inner diameter of the annular flame port 04.

[0030] Specifically, the plurality of through holes 21 arranged on the disc wall 20 are used to spin out the glass liquid 03 to form fibers under the action of centrifugal force, which can be through holes 21 with smaller hole diameters, as long as the glass liquid can be spun out by the centrifugal force, and the plurality of through holes 21 are densely distributed on the disc wall 20 to improve the production efficiency. The chamfer structure 30 arranged at the outer corner of the upper end of the disc wall 20 (that is, the corner part located at the outer side edge of the upper end) can be a single round corner structure or an inclined corner structure, or a combination of the two, and the core function is to change the rebound direction and airflow direction that the high-temperature flame flow may produce. The outer diameter of the disc wall 20 needs to be designed to be smaller than the inner diameter of the annular flame port 04, and the size relationship is determined after considering the thermal expansion amount of the centrifugal disc under the working temperature, as Figure 3 As shown in the figure, the solid part of the centrifugal disc main structure composed of the disc wall 20 and the upper edge 40 is the outer contour of the centrifugal disc in the cold state, and the virtual line on the right shows the structure contour after the centrifugal disc expands in the hot state, which is generally that the outer diameter of the disc wall 20 is slightly smaller than the inner diameter of the annular flame port 04, and at the same time, the high-temperature flame flow sprayed by the annular flame port 04 may produce slight diffusion when it leaves the flame channel, that is, the radial size of the flame flow will become larger, as Figure 3The high-temperature flame flow's inner fire ring 041 and outer fire ring 042's flame flow diffusion area (the area between the two dotted lines extending from the inner fire ring 041 and the outer fire ring 042), so when designing the outer diameter size of the disc wall 20, this should also be taken into account, in general, the outer diameter size of the disc wall 20 is sufficient to prevent the high-temperature flame flow from directly spraying on the upper edge of the centrifugal disc and producing disordered rebound inward or upward when working at high temperature, preventing hindering the smoke exhaust from the inside of the centrifugal disc to the outside, such as Figure 3 As shown, the direction indicated by the dotted arrow is the direction of the smoke exhaust generated in the centrifugal disc, and further ensures that there is an effective exhaust gap between the centrifugal disc and the high-temperature flame flow when working in a hot state, and prevents the flame flow from rebounding inward on the upper edge of the centrifugal disc.

[0031] In the embodiment, the centrifugal disc for centrifugal cotton production provided by the embodiment can be applied to the production process of glass centrifugal cotton. The whole centrifugal disc is provided in a disc-shaped structure. The center of the horizontally arranged disc bottom 10 is connected with the rotating main shaft 02 of the centrifugal cotton production equipment. When the rotating main shaft 02 drives the centrifugal disc to rotate at a high speed, no obvious shaking is caused. In the production process, the centrifugal cotton production equipment can pour high-temperature glass liquid 03 into the centrifugal disc. The disc wall 20 is vertically arranged and provided with a plurality of uniformly distributed through holes 21. After the high-temperature glass liquid 03 enters the centrifugal disc, the high-temperature glass liquid 03 can uniformly diffuse to the disc wall 20 under the action of centrifugal force and be thrown out at a high speed through the through holes 21 to form uniform glass liquid strands. At the same time, the centrifugal cotton production equipment can spray high-temperature flames to the glass liquid strands thrown out by the outer circumference of the disc wall 20 through the annular flame port 04, so that the glass liquid strands are stretched into fibers by the flames. In addition, the upper end outer corner of the disc wall 20 is provided with a chamfer structure 30. The flow state of the high-temperature flame flow when impinging on the upper edge of the centrifugal disc is fundamentally changed. The disordered rebound and diffusion caused by the vertical impingement on the straight edge of the disc wall 20 are changed into orderly guided flow along the chamfered slope or arc surface. At the same time, the outer diameter of the disc wall 20 is designed to be smaller than the inner diameter of the annular flame port 04, so that necessary radial space is reserved for thermal expansion. Even in a high-temperature working state, a stable annular exhaust passage can be maintained between the centrifugal disc and the inner wall of the annular flame port 04, and the flame is further prevented from being directly sprayed to the upper edge of the centrifugal disc. Through the above structure, the annular high-speed flame flow sprayed downward is guided to be inclined downward and outward when contacting the chamfer structure. Based on the principle of fluid mechanics, an exhaust effect is generated when the guided airflow flows through the exhaust passage, so that the smoke generated by, for example, the internal combustion head 05 is continuously and actively exhausted from the inside of the centrifugal disc, thereby significantly reducing the pressure in the disc from positive pressure to zero pressure or micro-negative pressure. Finally, the change of the pressure state eliminates the adverse phenomenon that the smoke escapes upward from the glass liquid 03 feeding port 07 and causes impact disturbance to the falling glass liquid strands, so that the glass liquid strands can stably and continuously fall, and the production interruption problem caused by the swinging and adhesion of the strands to the feeding port is solved, and the continuity and running stability of the centrifugal cotton production are significantly improved.

[0032] Optionally, as shown in Figures 1 to 3 the centrifugal disc for centrifugal cotton production further comprises an upper edge 40 connected with the upper end of the disc wall 20. The upper edge 40 is an annular plate structure and extends along the upper end of the disc wall 20 to the central axis of the disc wall 20. The chamfer structure 30 is arranged at the connecting outer corner of the upper edge 40 and the disc wall 20.

[0033] Specifically, the upper edge 40 extends horizontally inward, forming a ring-shaped "eave" structure. The chamfer structure 30 is specifically machined at the corner formed by the intersection of the outer edge of the upper edge 40 and the outer side wall of the disc wall 20. This structure makes the upper edge of the centrifugal disc smoother, further optimizing the airflow path.

[0034] In this embodiment, by setting the upper edge 40 and placing the chamfer structure 30 at the outer corner, the rigidity of the upper edge of the centrifugal disc is enhanced, which helps to inhibit thermal deformation, and the upper edge 40 can also prevent the glass liquid 03 from being thrown out from the inner upper end of the disc wall 20 when the centrifugal disc rotates at high speed, effectively blocking the glass liquid 03 and improving the stability of production. At the same time, this structure provides a better machining and stress basis for the chamfer, which can more effectively guide the flame and high-temperature gas flow that may impact here away from the central area of the disc, strengthening the sealing and flow guiding effect and further ensuring the stability of production.

[0035] Optionally, as shown in Figures 1 to 3 The chamfer structure 30 includes a continuous round corner 31 and a continuous bevel corner 32, and the round corner 31 is located above the bevel corner 32.

[0036] Specifically, the chamfer structure 30 is composed of an upper continuous round corner 31 and a lower continuous bevel corner 32. This composite chamfer structure 30 can better disperse thermal stress by using the round corner 31, and provide a better gas dynamics guiding surface by using the bevel corner 32.

[0037] In this embodiment, by adopting the composite chamfer structure 30 composed of the round corner 31 and the bevel corner 32, the upper corner of the centrifugal disc has both excellent thermal stress resistance of the round corner transition, prolonging the service life of the component, and the lower bevel corner provides a clear directional outflow channel for the flame and smoke, thereby realizing the unity of structural durability and functional efficiency, further optimizing the smoke exhaust effect and the long-term working reliability of the centrifugal disc, and setting the round corner 31 on the upper side makes the part that may be first impacted by the high-temperature flame flow smoother, forming a more stable transition and guidance, further improving the stability of the overall operation.

[0038] Optionally, as shown in Figures 1 to 3 The chamfer structure 30 is a round corner structure.

[0039] Specifically, the chamfer structure 30 can be a round corner structure as a whole. That is, the intersection line of the outer edge of the upper edge 40 and the outer side wall of the disc wall 20 is machined into a smooth round arc transition.

[0040] In the embodiment, by setting the chamfer structure 30 as a complete rounded corner, so that there is no sharp corner at the site, stress concentration can be extremely effectively avoided, and the thermal fatigue resistance is improved. At the same time, the smooth arc surface can also guide the airflow to adhere and flow, thereby achieving the purpose of smooth smoke exhaust. This is an implementation scheme with advantages in manufacturing process and comprehensive performance.

[0041] Optionally, as shown in Figures 1 to 3 The chamfer structure 30 is a bevel structure.

[0042] Specifically, the chamfer structure 30 can also be a bevel structure (or "chamfer surface") as a whole. That is, for example, a conical annular inclined surface is formed by cutting processing.

[0043] In the embodiment, by setting the chamfer structure 30 as a bevel, a guide slope with a clear angle is formed. The slope can provide an "glide ramp" with high efficiency for the downward spraying flame, thereby accurately guiding the flow direction to the outside and minimizing the centripetal flow component. This is an implementation scheme that can be more advantageous in flow guiding functionality.

[0044] Optionally, as shown in Figure 1 and Figure 2 The centrifugal cotton production centrifugal disc further comprises a transition ring plate 50 connected between the disc wall 20 and the disc bottom 10, and the transition ring plate 50 is inclined relative to the vertical plane.

[0045] Specifically, the disc bottom 10 is a horizontally arranged circular ring plate structure, the transition ring plate 50 is a funnel-shaped ring plate structure, and the disc wall 20 is a circular tube-shaped ring plate structure. The transition ring plate 50 is connected between the bottom of the disc wall 20 and the outer edge of the disc bottom 10. The inclined structure forms a transition area inside the centrifugal disc that gradually spreads from the center to the disc wall 20, which helps to guide the glass liquid 03 to flow more smoothly to the through hole 21 on the disc wall 20 under the action of centrifugal force.

[0046] In the embodiment, by setting the inclined transition ring plate 50 between the disc wall 20 and the disc bottom 10, the resistance of the glass liquid 03 flowing from the center of the disc bottom 10 to the peripheral side is reduced, and the flow is more smooth, thereby helping to form a glass liquid layer with more uniform thickness inside the disc wall 20, ensuring that the glass liquid strands spun out of each through hole 21 are uniform in thickness, and ultimately helping to improve the quality uniformity of the finally formed fiber cotton.

[0047] Optionally, as shown in Figure 1 and Figure 2As shown, the centrifugal cotton production centrifugal disc is integrally formed as a whole, and the inner side connection of the upper edge 40, the disc wall 20, the transition ring plate 50, and the disc bottom 10 is provided as a circular arc transition structure.

[0048] Specifically, the centrifugal cotton production centrifugal disc is preferably integrally formed by casting or spinning process using heat-resistant alloy. The upper edge 40, the disc wall 20, the transition ring plate 50, and the disc bottom 10 are all connected at the inner side with a circular arc transition, eliminating the sharp corners inside.

[0049] In this embodiment, by using an integral molding process and all internal circular arc transitions, the structure of the entire centrifugal disc has high strength, small fluid (glass liquid 03 and flue gas) flow resistance, and no dead angle. At the same time, this structure can evenly distribute thermal stress, greatly reducing the risk of cracks or deformation under high-temperature high-speed rotating conditions, thereby significantly improving the service life and reliability of the centrifugal disc.

[0050] Optionally, as shown in Figure 1 and Figure 2 The upper end surface of the disc bottom 10 is provided with a circular table structure 11, the circular table structure 11 is coaxially arranged with the disc bottom 10, and the disc bottom 10 is provided with a mounting hole 13 for connecting the rotating main shaft 02 at the center of the circular table structure 11.

[0051] Specifically, the circular table structure 11 can be formed by stamping the center of the disc bottom 10 upward, or by thickening the thickness of the center of the disc bottom 10 to form a circular table structure 11 such as a cylindrical structure. The convex design of the circular table structure 11 increases the local thickness and structural strength of the connection area of the main shaft.

[0052] In this embodiment, by providing a circular table structure 11 on the upper end surface of the disc bottom 10, the connecting surface of the lower end of the rotating main shaft 02 is positioned and strengthened, improving the rigidity of the connection part. Further, under high-speed rotating conditions, this structure helps to ensure the stability of the connection between the centrifugal disc and the rotating main shaft 02, reduces the possible micro-displacement and vibration, and ultimately provides important upper support for the smooth operation of the centrifugal disc. At the same time, the circular table structure 11 can also prevent the centrifugal disc and the rotating main shaft 02 from splashing when the high-temperature glass liquid 03 is poured downward, and further protects the rotating main shaft 02.

[0053] Optionally, as shown in Figure 1 and Figure 2As shown, the lower end surface of the disc bottom 10 is provided with a circular groove 12, which is coaxially arranged with the disc bottom 10, and the disc bottom 10 is provided with a mounting hole 13 at the center of the circular groove 12 for connecting the rotating main shaft 02, and the circular groove 12 is used for mounting the limiting boss at the lower end of the rotating main shaft 02.

[0054] Specifically, the centrifugal disc is integrally hoisted and fixed at the lower end of the rotating main shaft 02, and the circumferential wall of the lower end of the rotating main shaft 02 is provided with a circular limiting boss, the structure and size of the circular groove 12 correspond to the structure and size of the limiting boss, and further, the size of the circular groove 12 is designed to accommodate one limiting boss at the lower end of the rotating main shaft 02, so as to form a more stable connection structure.

[0055] In the embodiment, by arranging the circular groove 12 at the lower end surface of the disc bottom 10, the limiting boss at the lower end of the rotating main shaft 02 can be embedded in the groove during installation. Furthermore, the embedding structure realizes the accurate positioning and limiting of the main shaft and the centrifugal disc in the radial and axial directions, effectively prevents relative movement and loosening, and finally further enhances the coaxiality and operation reliability of the entire rotor system in the high-speed rotating state.

[0056] In addition, as shown in Figure 2 and Figure 4 Another embodiment of the utility model provides a centrifugal cotton production equipment, including main body 01, rotating main shaft 02, internal combustion head 05, drive mechanism and the centrifugal disc for centrifugal cotton production as described above, rotating main shaft 02 is rotatably connected to main body 01, drive mechanism drive connection rotating main shaft 02, the lower end of rotating main shaft 02 is connected with the center of the centrifugal disc for centrifugal cotton production, main body 01 is provided with annular combustion chamber 06, the lower end of annular combustion chamber 06 is provided with annular flame port 04 that passes through the lower end of main body 01, the inner diameter of annular flame port 04 is greater than the outer diameter of the centrifugal disc for centrifugal cotton production, internal combustion head 05 is hoisted in the lower end of main body 01, and internal combustion head 05 is located in the centrifugal disc for centrifugal cotton production, main body 01 is also provided with feeding port 07 that passes through the lower end of main body 01, for feeding glass liquid 03 into the centrifugal disc for centrifugal cotton production.

[0057] Specifically, the drive mechanism can be a motor cooperating with a transmission gear set to transmit rotary power, and the centrifugal cotton production equipment can further include other mechanisms and components, such as a glass liquid 03 feeding and heating mechanism, a natural gas supply structure cooperating with the annular combustion chamber 06 and the internal combustion head 05, and a plurality of internal combustion channels 08 vertically provided on the main body 01 to supply natural gas to the internal combustion head 05. Of course, the above is only a partial structure description of the centrifugal cotton production equipment, and other specific limitations are not made herein.

[0058] In the embodiment, the centrifugal cotton production equipment has the technical effects similar to those of the centrifugal cotton production centrifugal disc, and details are not repeated. Meanwhile, the main body 01, the rotating main shaft 02 and the driving mechanism constitute the core power and the support frame of the equipment. The annular combustion chamber 06 and the annular flame spout 04 at the lower end thereof provide the high-speed and high-temperature flame field required for forming and pulling fibers. The feeding opening 07 is arranged on the main body 01 to ensure continuous supply of the glass liquid 03. The inner diameter of the annular flame spout 04 is greater than the outer diameter of the centrifugal cotton production centrifugal disc, the internal combustion head 05 is hung at the lower end of the main body 01 and extends into the centrifugal disc, so that the whole equipment not only has the function of maintaining the micro-negative pressure in the disc by the airflow guiding and the injection effect during the operation of the centrifugal disc, but also builds a complete and efficient working cycle from the system level. That is, the glass liquid 03 is stably dropped into the centrifugal disc through the feeding opening 07, is spun into strands, the internal combustion head 05 maintains the temperature of the glass liquid 03, the generated flue gas is efficiently taken away by the flame injection flow, and the glass liquid 03 and the flue gas do not interfere with each other. Further, the equipment systematically eliminates the process fluctuation caused by the imbalance of the internal pressure, and finally ensures the continuous, efficient and stable operation of the centrifugal cotton production process as a whole.
