Description

Technical Field

[0001] The invention relates to the technical field of alkali-free glass production, in particular to a processing system for alkali-free glass fiber. Background Art

[0002] Alkali-free glass fiber, also known as E glass fiber, refers to glass fiber with a low content of alkali metal oxides. The specific content of alkali metal oxides is stipulated to be about 1% abroad and no more than 0.8% in China. The R2O content of alkali-free glass fiber is less than 0.8%. It is an aluminum borosilicate component with good chemical stability, electrical insulation performance and strength. It is mainly used as electrical insulation material, FRP reinforcement material and tire cord, and used in composite cable brackets.

[0003] The existing alkali-free glass fiber processing system uses borate stone, quartz sand, fluorite and other raw materials as raw materials and puts them into the melting unit kiln. After melting, clarifying and homogenizing in the melting unit kiln, high-quality glass liquid is obtained and then flows into the leak plate to form fibers. After being coated with a special wetting agent, most of them are drawn and wound into raw wire cakes by a high-speed rotating wire drawing machine, or a part of them are chopped online into short strands.

[0004] In the prior art, the leak plate is in the shape of a trough-shaped container. After the molten glass flows into the leak plate, it is modulated to a suitable temperature and then flows out through a nozzle to be stretched into continuous glass fibers by a high-speed rotating wire drawing machine. During this process, the leak plate needs to withstand high temperature, glass hydraulic pressure and the pulling force of the wire drawing machine. As the time of the wire drawing operation increases, the bottom plate of the leak plate begins to become unstable under the action of high temperature, glass hydraulic pressure and the pulling force of the wire drawing machine, and creep is prone to occur, resulting in uneven temperature distribution on the bottom surface of the leak plate and a large temperature difference between the two ends, which causes instability in the wire drawing operation, reduces the quality of the produced glass fiber, and in severe cases, crystallization and cracking may occur, affecting the service life of the leak plate.

DETAILED DESCRIPTION

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] See also Figures 1 to 6 , the present invention provides a technical solution:

[0037] A processing system for alkali-free glass fiber, such as Figure 1 As shown, including:

[0038] Bracket 1;

[0045] Temperature regulating mechanism 5;

[0046] The temperature regulating mechanism 5 penetrates and is fixedly connected to the upper end surface of the bracket 1, and can regulate the temperature of the high-temperature glass liquid.

[0047] During operation, the leak plate in the prior art needs to withstand high temperature, glass hydraulic pressure and the pulling force of the wire drawing machine. As the time of the wire drawing operation increases, the structure of the leak plate bottom plate begins to become unstable under the action of high temperature, glass hydraulic pressure and the pulling force of the wire drawing machine, and creep is easily generated, resulting in uneven temperature distribution on the bottom surface of the leak plate and a large temperature difference between the two ends, which causes instability in the wire drawing operation and reduces the quality of the produced glass fiber. In severe cases, crystallization and cracking may occur, affecting the service life of the leak plate. The present invention provides a temperature regulating mechanism 5, feeds the raw material into the spiral feeding assembly 2, and transports it into the melting point through the conveying assembly 3. After melting, clarifying and homogenizing in the box 4, the glass enters the temperature regulating mechanism 5. After the temperature regulating mechanism 5 is temperature-regulated, the glass is pulled by the wire drawer 8, and after being processed by the oiler 6 and the buncher 7, the glass enters the wire drawer 8 to be drawn into raw wire. The present invention sets the temperature regulating mechanism 5 to adjust the temperature, thereby preventing the bottom plate of the leak plate from becoming unstable and causing creep under the action of long-term high temperature, glass hydraulic pressure and tension, avoiding uneven bottom plate temperature resulting in unstable temperature at both ends, thereby preventing the wire drawing operation from being unstable, avoiding the quality of the produced glass fiber from being reduced, and preventing crystallization and cracking from reducing the service life of the leak plate.

[0048] As an embodiment of the present invention, Figure 2 and Figure 3 As shown, the temperature control mechanism 5 includes a side plate 51, a flange 52, a bottom plate 53, a nozzle 54, a filter 55, a temperature control plate 56, a lower plug 57, an upper plug 58, a terminal 59, a leak hole 510 and a cooling fin 513; the upper end surface of the bracket 1 is penetrated by a side plate 51; the upper end surface of the side plate 51 is fixedly connected with a flange 52; the lower end surface of the side plate 51 is fixedly connected with a bottom plate 53; the lower surface of the bottom plate 53 is penetrated and fixedly connected with nozzles 54 evenly distributed; the inner wall of the side plate 51 is fixedly connected with a filter 55 near the upper edge; the inner wall of the side plate 51 is fixedly connected with a temperature control plate 56 at the lower middle position; Two lower plugs 57 are symmetrically fixedly connected to the upper surface of the plate 56 near the left and right edges; the upper surface of the temperature regulating plate 56 is provided with evenly distributed leakage holes 510 between the two lower plugs 57; the upper surface of the temperature regulating plate 56 is provided with cooling fins 513; the upper surface of the lower plug 57 is fixedly connected to the edge of one side of the side plate 51; the lower plug 57 and the upper plug 58 are fixedly connected to the inner wall of the side plate 51; the positions of the left and right outer surfaces of the side plate 51 corresponding to the lower plugs 57 are penetrated by fixed connection terminals 59, and the two connection terminals 59 are fixedly connected to the lower plugs 57 on the left and right sides, respectively.

[0049] During operation, in order to solve the problem that the leak plate in the prior art needs to withstand the high temperature of the glass liquid and the pulling force of the wire drawing machine, the bottom surface structure of the leak plate may become unstable and easily creep under the action of a long time, resulting in uneven temperature on the bottom surface of the leak plate and a large temperature difference between the two ends, which causes instability in the wire drawing operation, reduces the quality of the produced glass fiber, and in severe cases, crystallization and crack flow may occur, affecting the service life of the leak plate; the present invention is provided with a temperature regulating mechanism 5, the glass liquid flows through the temperature regulating mechanism 5, is filtered by the filter screen 55, and then flows downward to the top of the temperature regulating plate 56, and is heated by the lower plug 57, the upper plug 58 and the wiring terminal 59 on the left and right sides, and the cooling plate 5 provided on the upper surface of the temperature regulating plate 56 is provided. 13 realizes the temperature control of the glass liquid under the combined effect of cooling it, and then flows into the top of the bottom plate 53 through the leakage hole 510, and then draws the glass liquid through the wire drawer 8 and pulls it out from the nozzle 54; the present invention arranges a temperature control mechanism 5, and uses the temperature control plate 56 arranged inside the abdominal cavity of the side plate 51 to adjust the temperature, thereby avoiding the traditional method of using the bottom plate 53 for temperature control, so that when the bottom plate 53 is subjected to the creep caused by high temperature, glass hydraulic pressure and the pulling force of the wire drawer 8, the temperature uniformity can still be guaranteed. At the same time, by arranging the temperature control plate 56, the force of the high temperature, glass hydraulic pressure and the pulling force of the wire drawer 8 on the bottom plate 53 can be partially reduced, thereby extending the life of the nozzle 54.

[0050] As an embodiment of the present invention, Figure 3 and Figure 4 As shown, light plates 511 are fixedly connected to the four corners of the lower surface of the bottom plate 53 , and the light plates 511 seal part of the nozzles 54 .

[0051] During operation, when the temperature regulating mechanism 5 regulates the temperature of the glass liquid, the temperature of the four corners of the temperature regulating plate 56 tends to become lower, resulting in uneven temperature of the glass liquid, which leads to instability in the wire drawing operation and reduced quality of the produced glass fiber. The present invention sets a light plate 511 and seals part of the nozzles 54 at the corners. The light plate 511 is fixedly connected to the four corners of the lower surface of the bottom plate 53 and seals part of the nozzles 54. The glass liquid on the bottom plate 53 will not flow out from the four corners of the bottom plate 53. The present invention sets a light plate 511 and seals part of the nozzles 54 at the corners. The influence of heat dissipation at the corners of the bottom plate 53 on the temperature of the glass liquid on the bottom plate 53 can be reduced. The nozzles 54 sealed at the corners can form a heat preservation zone, thereby enhancing the uniformity of the temperature in the nozzle 54 zone.

[0052] As an embodiment of the present invention, Figure 3 As shown, the distance between two adjacent leakage holes 510 is twice the distance between adjacent nozzles 54 .

[0053] During operation, when the temperature regulating plate 56 regulates the temperature of the glass liquid, the cooling fins 513 have a short service life and need to be replaced frequently. The small spacing between the leakage holes 510 on the temperature regulating plate 56 may make it difficult to replace the cooling fins 513, causing the temperature regulating plate 56 to be poisoned and cause leakage. The present invention reduces the difficulty of replacing the cooling fins 513 by limiting the spacing between two adjacent leakage holes 510 to twice the spacing between adjacent nozzles 54, thereby solving the problem of difficulty in replacing the cooling fins 513 caused by the small spacing between the leakage holes 510 and avoiding the problem of leakage caused by the temperature regulating plate 56 being poisoned.

[0054] As an embodiment of the present invention, Figure 5 As shown, a heat-insulating layer 514 is provided on the inner wall of the side plate 51 between the temperature-adjusting plate 56 and the bottom plate 53 .

[0055] During operation, the glass liquid, after being temperature-regulated by the temperature-regulating plate 56, flows through the leak hole 510 into the cavity between the temperature-regulating plate 56 and the bottom plate 53, and then is drawn out from the nozzle 54 through the wire drawing device 8. During this process, the glass liquid stays in the cavity between the temperature-regulating plate 56 and the bottom plate 53 for a certain period of time. This period of time may cause the temperature of the glass liquid to drop, and the uneven temperature of the glass liquid may cause the wire drawing to fail, resulting in reduced production quality of the glass fiber. The present invention provides a heat-insulating layer 514, The glass liquid flows through the leakage hole 510 into the cavity below the temperature regulating plate 56 in the temperature regulating mechanism 5, and the insulation layer 514 arranged on the side wall of the cavity insulates the glass liquid. The present invention reduces the heat loss of the glass liquid when it stays in the cavity between the temperature regulating plate 56 and the bottom plate 53 in the side plate 51 by arranging the insulation layer 514, avoids the temperature drop of the glass liquid in the cavity between the temperature regulating plate 56 and the bottom plate 53, prevents the occurrence of wire drawing failure, and avoids the reduction of the production quality of the glass fiber.

[0056] As an embodiment of the present invention, Figure 5 As shown, the thermal insulation layer 514 is a ceramic fiber material component.

[0057] During operation, the oxidation point of alkali-free glass is 840°C and the drawing point is 1300°C. The insulation layer 514 of ordinary material will melt or even burn in this high temperature environment, which will pollute the glass liquid flowing over the bottom plate 53, resulting in reduced production quality of glass fiber, and even damage to the temperature control mechanism 5 in severe cases. The present invention limits the insulation layer 514 to a ceramic fiber material component. The ceramic fiber can work normally in a high temperature environment of 1000°C to 1790°C, and the thermal conductivity of the ceramic fiber is low. It can keep the glass liquid flowing between the temperature control plate 56 in the side plate 51 and the bottom plate 53 warm, avoid the melting or burning of the insulation layer 514, and cause pollution of the glass liquid flowing over the bottom plate 53, reduce the occurrence of reduced production quality of glass fiber, and reduce the occurrence of damage to the temperature control mechanism 5.

[0058] As an embodiment of the present invention, Figure 3 As shown, the thickness of the lower plug 57 is 1.5 times the thickness of the upper plug 58 .

[0059] During operation, when the temperature regulating plate 56 regulates the temperature of the glass liquid, when the temperature regulating plate 56 is conducting electricity, the current mainly flows from the terminal 59 at one end of the temperature regulating plate 56 through the upper plug 58, the lower plug 57, and the temperature regulating plate 56 to the terminal 59 at the other end. This causes a difference in the temperature of the glass liquid in the vertical direction at both ends of the temperature regulating plate 56, which will affect the quality of the produced glass fiber and the smooth production. The present invention limits the thickness of the lower plug 57 to 1.5 times the thickness of the upper plug 58. When the thickness of the lower plug 57 is greater than the thickness of the upper plug 58 and is 1.5 times the thickness of the upper plug 58, the temperature of the glass liquid in the vertical direction at both ends of the temperature regulating plate 56 can be regulated, which can effectively ensure the production quality of the produced glass fiber, prevent the smooth glass production from being affected, and also ensure the service life of the temperature regulating plate 56.

[0060] As an embodiment of the present invention, Figure 3 As shown, the upper surface of the temperature regulating plate 56 is fixedly connected with uniformly distributed reinforcing ribs 512 , and the two ends of the reinforcing ribs 512 are respectively fixedly connected to the inner surfaces of the front and rear sides of the side plate 51 .

[0061] During operation, the impact of the high-temperature glass liquid on the temperature regulating plate 56 and the pulling force of the wire drawer 8 on it cause the supporting strength of the temperature regulating plate 56 to be reduced. In severe cases, it will be directly damaged, making it impossible to continue the production of glass fiber. At the same time, long-term impact and pressure will also cause the service life of the temperature regulating plate 56 to be greatly reduced. The present invention arranges reinforcing ribs 512, and the reinforcing ribs 512 can increase the surface strength of the temperature regulating plate 56, overcome the deformation of the temperature regulating plate 56 on the horizontal plane caused by the impact of the high-temperature glass liquid and the pulling force of the wire drawer 8, and enhance the strength and rigidity of the temperature regulating plate 56. The present invention arranges reinforcing ribs 512, which can overcome the impact and pulling force on the temperature regulating plate 56 by strengthening the strength and rigidity of the temperature regulating plate 56, ensure that the temperature regulating plate 56 has sufficient supporting strength, avoid damage to the temperature regulating plate 56 so as to affect the normal production process of the glass fiber, and avoid shortening the service life of the temperature regulating plate 56.

[0062] As an embodiment of the present invention, Figure 6 As shown, the cross section of the reinforcing rib 512 is T-shaped; the reinforcing rib 512 is evenly distributed on the upper surface of the temperature regulating plate 56, and the reinforcing rib 512 is located between the leakage holes 510.

[0063] During operation, the multiple reinforcing ribs 512 fixedly connected on the upper surface of the temperature regulating plate 56 may affect the normal operation of the leakage holes 510. The connection between the reinforcing ribs 512 and the temperature regulating plate 56 may cause blockage to some of the leakage holes 510, resulting in the glass liquid after temperature adjustment being unable to flow quickly to the top of the bottom plate 53, resulting in reduced production efficiency of the glass fiber. The present invention limits the cross-section of the reinforcing ribs 512 to be T-shaped, and the reinforcing ribs 512 are evenly distributed on the upper surface of the temperature regulating plate 56, and the reinforcing ribs 512 are located between the leakage holes 510. The T-shaped setting is to allow the reinforcing ribs 512 themselves to have sufficient supporting strength, limit the reinforcing ribs 512 to be evenly distributed to enhance the supporting strength of the temperature regulating plate 56 with the maximum strength, and limit the reinforcing ribs 512 to be located between the leakage holes 510, so as to prevent the leakage holes 510 from being affected in their normal operation, and also avoid affecting the cooling fins 513.

[0064] As an embodiment of the present invention, Figure 6 As shown, the height of the reinforcing rib 512 is 14 to 18 mm.

[0065] When working, the material thickness and height of the reinforcing rib 512 will have a direct impact on its strength. The height of the reinforcing rib 512 will directly affect the rigidity of its body. If it is too high, the reinforcing rib 512 will be too heavy and will impose a certain burden on the temperature regulating plate 56. If it is too short, the rigidity of the reinforcing rib 512 will be too poor and it will not be able to support the temperature regulating plate 56. The present invention limits the height of the reinforcing rib 512 to 14-18 mm, which can meet the required support strength of the temperature regulating plate 56 and extend the service life of the temperature regulating plate 56, thereby avoiding the excessive weight of the reinforcing rib 512 that causes a burden on the temperature regulating plate 56 and avoiding the poor rigidity of the reinforcing rib 512 that causes a burden on the temperature regulating plate 56.

[0066] Instructions for use: When the present invention is in use, the raw materials are put into the spiral feeding component 2, conveyed by the conveying component 3 into the melting box 4 for melting, clarification, homogenization, and then enter the temperature control mechanism 5. The glass liquid flows through the temperature control mechanism 5, is filtered by the filter screen 55, and then flows downward to the top of the temperature control plate 56. The glass liquid is heated by the lower plug 57, the upper plug 58 and the connecting terminal 59 on the left and right sides and cooled by the cooling plate 513 on the upper surface of the temperature control plate 56. The glass liquid is temperature-controlled, and then flows into the top of the bottom plate 53 through the leakage hole 510. The glass liquid is then drawn by the wire drawer 8 and pulled out from the nozzle 54. After being processed by the oiler 6 and the buncher 7, it enters the wire drawer 8 and is drawn into raw wire.
