Description

Technical Field

[0001] This invention relates to the field of thermal insulation cotton production technology, specifically to a centrifuge for thermal insulation cotton production. Background Technology

[0002] The centrifuge used in the production of thermal insulation cotton is used to process the glass fibers in the thermal insulation cotton. During the processing, molten glass is made into filaments by centrifugation. During the production process, the molten glass flows into the centrifuge disc, which has multiple small holes. Under the action of centrifugal force, the molten glass is thrown out of the small holes into glass filaments, and then blown into microfibers under the action of the stretching airflow of the high-temperature flame.

[0003] In existing technologies, when high-temperature flames blow and stretch glass fibers, the air is typically blown from top to bottom. This causes the spun glass fibers to be stretched downwards by the downward-blowing stretching airflow from the high-temperature flame, resulting in the fibers bending and breaking at the small holes on the centrifuge disc. Consequently, the glass fibers lack a support point, and the stretching airflow cannot effectively stretch them, increasing the diameter of the fibers and reducing the quality of glass fiber production. Furthermore, if the small holes on the centrifuge disc become clogged, it requires prolonged machine shutdowns for manual repairs. This reduces production efficiency, and the prolonged shutdowns cause the centrifuge disc temperature to drop, requiring subsequent extended heating to restore it, thus reducing ease of use. Summary of the Invention

[0004] To overcome the aforementioned technical problems, the present invention aims to provide a centrifuge for producing thermal insulation cotton. This addresses the issue in the prior art where, after being spun out, the glass fibers are stretched and bent downwards by the downward-blowing stretching airflow from a high-temperature flame. Consequently, the glass fibers bend and break at the small holes on the centrifuge disc, leaving them without support points. This prevents the stretching airflow from providing sufficient stretching effect, increasing the diameter of the glass fibers and reducing the quality of glass fiber production. Furthermore, blockage of the small holes on the centrifuge disc requires prolonged shutdowns and manual repairs, reducing production efficiency. Additionally, prolonged shutdowns cause the centrifuge disc temperature to drop, necessitating subsequent prolonged heating for restoration, thus compromising ease of use.

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

[0006] A centrifuge for producing thermal insulation cotton includes an outer cylinder and a centrifugal disc. The centrifugal disc is rotatably connected inside the outer cylinder. Multiple sets of yarn outlet holes are formed on the outer wall of the centrifugal disc. An air-blowing ring is fixedly connected to the outer wall of the centrifugal disc. An annular cavity is formed inside the air-blowing ring. Multiple sets of circumferentially arrayed air outlet holes are formed on the outer wall of the annular cavity, penetrating the air-blowing ring. The positions of the multiple sets of air outlet holes are aligned with the positions of the multiple sets of yarn outlet holes. A lifting cylinder is fixedly connected to the top of the outer cylinder. A fixed plate is fixedly connected to the output end of the lifting cylinder. A cleaning chamber is formed inside the fixed plate. Multiple sets of push rods are slidably connected inside the cleaning chamber. One end of each push rod penetrates the fixed plate and cooperates with the yarn outlet holes for cleaning.

[0007] As a further aspect of the present invention: there are multiple sets of air-blowing rings, and the multiple sets of air-blowing rings are respectively arranged alternately with multiple sets of wire outlet holes. The multiple sets of air-blowing rings are connected to each other through connecting pipes. A rotary joint is fixedly connected to the bottom of the centrifugal disc, and the rotary joint is connected to one set of air-blowing rings through an air supply pipe.

[0008] As a further aspect of the present invention: the air outlet holes on each group of air blowing rings are arranged in two symmetrical circumferential arrays and are opened at an angle in opposite directions in a V shape.

[0009] As a further aspect of the present invention: an airbag is provided inside the cleaning chamber, a push plate is provided on one side of the airbag, one side of the push plate is fixedly connected to a push rod, an air supply pump is fixedly connected to the top of the outer cylinder, and the output end of the air supply pump is connected to the airbag through an air supply pipe.

[0010] As a further aspect of the present invention: a spring is sleeved on the outer wall of the push rod, and the two ends of the spring abut against the inner wall of the cleaning cavity and the push plate, respectively.

[0011] As a further aspect of the present invention: the outer wall of the fixed disk is attached to the inner wall of the centrifugal disk.

[0012] As a further aspect of the present invention: a feed cylinder is fixedly connected to the top of the outer cylinder, and the bottom of the feed cylinder is located on the upper side of the centrifugal disc.

[0013] As a further aspect of the present invention: a connecting frame is fixedly connected to the bottom of the feed cylinder, and multiple sets of circumferentially arrayed flame guns are fixedly connected to the bottom of the connecting frame.

[0014] The beneficial effects of this invention are:

[0015] 1. In this invention, air entering the annular cavity inside the blowing ring is ejected from the air outlet. The air blown from the air outlet is in the same direction as the glass fiber ejected from the fiber outlet. While cooling the glass fiber, a pushing force is applied to the glass fiber to avoid insufficient pushing and pulling force when the glass fiber is ejected from the fiber outlet. At the same time, the glass fiber is stretched to reduce its diameter and improve the quality of the glass fiber ejected from the fiber outlet.

[0016] 2. In this invention, by starting the air supply pump, the air supply pump draws air and sends it into the airbag through the air supply pipe. The airbag expands and pushes multiple sets of push plates to move. The multiple sets of push plates drive multiple sets of push rods to move out of the cleaning chamber and then slide into the water outlet hole, thereby pushing out the impurities blocking the wire outlet hole, thus completing the cleaning of the wire outlet hole blockage, reducing the danger and cleaning time of manual cleaning during downtime, and improving the convenience and efficiency of cleaning.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] like Figures 1-3As shown, a centrifuge for producing thermal insulation cotton includes an outer cylinder 1 and a centrifuge disc 2. The centrifuge disc 2 is rotatably connected inside the outer cylinder 1. A drive motor 301 is fixedly connected to the bottom of the centrifuge disc 2 to drive its rotation. Multiple sets of yarn outlet holes 3 are opened on the outer wall of the centrifuge disc 2. An air blowing ring 4 is fixedly connected to the outer wall of the centrifuge disc 2. An annular cavity 401 is opened inside the air blowing ring 4. Multiple sets of circumferentially arrayed air outlet holes 402 are opened on the outer wall of the annular cavity 401, penetrating the air blowing ring 4. The positions of the multiple sets of air outlet holes 402 are aligned with the positions of the multiple sets of yarn outlet holes 3, so that the air outlet holes 402 blow out The stretching airflow is in the same direction, so that after the glass fiber is ejected from the fiber outlet 3, a push-pull force in the same direction is applied to it, thereby further reducing the diameter of the glass fiber and improving the quality of the glass fiber. A lifting cylinder 5 is fixedly connected to the top of the outer cylinder 1, and a fixed plate 6 is fixedly connected to the output end of the lifting cylinder 5. The outer wall of the fixed plate 6 is in contact with the inner wall of the centrifugal disc 2. A cleaning chamber 601 is opened inside the fixed plate 6. Multiple sets of push rods 701 are slidably connected inside the cleaning chamber 601. One end of the multiple sets of push rods 701 passes through the fixed plate 6 and cooperates to clean the fiber outlet 3.

[0024] like Figure 1 and Figure 2 As shown, there are multiple sets of air-blowing rings 4, which are staggered with multiple sets of wire outlet holes 3 to provide blowing and pulling force to the multiple sets of circumferential array wire outlet holes 3. At the same time, the multiple sets of air-blowing rings 4 are connected to each other through connecting pipes. A rotary joint 403 is fixedly connected to the bottom of the centrifugal disc 2. The rotary joint 403 is connected to a set of air-blowing rings 4 through an air supply pipe 404, so that air can be supplied to the inside of the air-blowing rings 4 when the centrifugal disc 2 rotates.

[0025] like Figure 1 and Figure 2 As shown, furthermore, the air outlets 402 on each set of blowing rings 4 are arranged in two symmetrical circumferential arrays and are opened in opposite V-shapes. This arrangement causes the stretching airflow blown from the two sets of air outlets 402 on the sidewalls of the two sets of blowing rings 4 to collide when they reach the intersection point. When the glass fiber ejected from the filament outlet 3 between the two sets of blowing rings 4 reaches the intersection point, the collision of the stretching airflow from the two sets of air outlets 402 provides a stronger blowing and pulling force to the glass fiber, thereby blowing and pulling the glass fiber into finer glass wool and improving the quality of the glass fiber ejected from the filament outlet 3.

[0026] like Figure 1 and Figure 3As shown, the cleaning chamber 601 described above is equipped with an airbag 702. A push plate 7 is provided on one side of the airbag 702. One side of the push plate 7 is fixedly connected to the push rod 701. An air supply pump 703 is fixedly connected to the top of the outer cylinder 1. The output end of the air supply pump 703 is connected to the airbag 702 through the air supply pipe 704. A spring 705 is sleeved on the outer wall of the push rod 701. The two ends of the spring 705 abut against the inner wall of the cleaning chamber 601 and the push plate 7, respectively. The lifting cylinder 5 drives the fixed plate 6 to move to the position of the blocked wire outlet hole 3 for alignment. Then, the air supply pump 703 is started to draw air into the airbag 702 through the air supply pipe 704. The airbag 702 inflates and abuts against the push plate 7, pushing the push plate 7 to move. The push plate 7 drives the push rod 701 to move out of the cleaning chamber 601 and then slide into the wire outlet hole 3, thereby pushing out the impurities in the wire outlet hole 3 for cleaning, improving the convenience of cleaning.

[0027] like Figure 1 As shown, the top of the outer cylinder 1 is fixedly connected to the feed cylinder 8, the bottom of the feed cylinder 8 is located on the upper side of the centrifugal disc 2, the bottom of the feed cylinder 8 is fixedly connected to the connecting frame 801, and the bottom of the connecting frame 801 is fixedly connected to multiple sets of circumferentially arrayed flame guns 9. The molten glass solution is fed into the centrifugal disc 2 through the feed cylinder 8, and then the multiple sets of flame guns 9 are activated to heat the glass solution that has entered the centrifugal disc 2, keeping it in a molten state, so that the glass solution can be sprayed out into the fiber outlet hole 3 on the outer wall of the centrifugal disc 2 to form glass fibers.

[0028] The working principle of this invention is as follows: During operation, the user adds molten glass solution into the centrifuge disc 2 through the feeding cylinder 8. Simultaneously, the flames from the circumferential array of flame guns 9 at the bottom of the connecting frame 801 heat the glass solution, maintaining a temperature of 1400°C inside the centrifuge disc 2, thus keeping the glass solution molten. Then, the drive motor 301 is activated, causing the centrifuge disc 2 to rotate. This rotation ejects the molten glass solution through the wire outlet 3, forming fine glass fibers. Simultaneously, a fan draws air and introduces it into the centrifuge disc. Inside the rotary joint 403, air is supplied through the air supply pipe 404 into a set of air-blowing rings 4. Multiple sets of air-blowing rings 4 are connected by connecting pipes for air supply. The air entering the annular cavity 401 inside the air-blowing ring 4 is ejected through the air outlet 402. The air blown out of the air outlet 402 is in the same direction as the glass fiber ejected from the fiber outlet 3. While cooling the glass fiber, a pushing force is applied to the glass fiber to prevent insufficient pushing and pulling force from ejecting the glass fiber from the fiber outlet 3, thereby improving the quality of the glass fiber ejected from the fiber outlet 3. When the fiber outlet 3 is exposed to air for a long time... When a blockage occurs, the centrifugal disc 2 stops rotating and returns to its initial state by stopping the drive motor 301. Then, the lifting cylinder 5 is activated, which moves the fixed disc 6 downward to align with the wire outlet hole 3 of the blocked circumferential array. Next, the air supply pump 703 is activated, drawing air and sending it into the airbag 702 through the air supply pipe 704. The airbag 702 expands, pushing multiple sets of push plates 7 to move. These push plates 7 move multiple sets of push rods 701 out of the cleaning chamber 601 and into the wire outlet hole 3, thus pushing out the blockage and removing the impurities. The blockage removal of the paired wire outlet holes 3 reduces the danger and time of manual cleaning during downtime, and improves the convenience and efficiency of cleaning. After cleaning, the air supply pump 703 is stopped. At this time, the tension of the spring 705 abuts against the push plate 7, which drives the push rod 701 to move out of the wire outlet hole 3 and into the cleaning chamber 601 for reset. At the same time, the push plate 7 squeezes the air bag 702 to squeeze out the air inside the air bag 702 and reset it. Then, the lifting cylinder 5 is started to drive the fixed plate 6 to move upward and move out of the position of the wire outlet hole 3. The drive motor 301 is started again to drive the centrifugal disc 2 to rotate for centrifugal operation.

[0029] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
