Description

Technical Field

[0001] This utility model relates to the field of glass fiber acid leaching treatment technology, specifically a high-silica glass fiber acid leaching treated tube. Background Technology

[0002] High-silica glass fiber yarn possesses characteristics such as corrosion resistance and high-temperature resistance, and is mainly used in textiles for various reinforcement, corrosion resistance, and heat insulation purposes, widely applied in aerospace and other fields. High-silica glass fibers and their various products are generally prepared from alkali-free glass fibers, borosilicate glass fibers, and sodium silicate glass fibers. Although the raw material compositions for preparing various high-silica glass fibers and their products differ, after acid treatment, the SiO2 content in the fibers can reach 94%-98%, allowing for long-term use in high-temperature environments of 900℃-1000℃.

[0003] According to customer needs, the binary high-silica textile fiber raw filaments in the tank furnace undergo multiple processes during the production cycle to produce semi-finished products with various requirements. The semi-finished products are then acid-leached, washed, and dried to finally form finished high-silica products (such as high-silica textile continuous fibers and fabrics).

[0004] The current processing technology involves first twisting binary high-silica continuous fiber filaments into untwisted yarn of the required twist, then plying them into parallel-twisted continuous fiber yarn according to the production process. The qualified binary high-silica parallel-twisted continuous fiber yarn is then processed into high-silica woven fabric products using textile equipment. Next, the high-silica textile continuous fibers and fabric products undergo a chemical reaction in a sulfuric acid solution of a certain concentration, precipitating Na2O from the high-silica textile continuous fibers and fabric products, resulting in a SiO2 content ≥96%. Finally, the products are washed, dried, inspected, and stored. Existing processes generally involve spinning first, followed by acid treatment, but the subsequent acid treatment is ineffective. Some processes involve acid treatment first, followed by spinning, but regardless of the method, the products are directly immersed in an acid bath for pickling. There is room for improvement in both pickling efficiency and overall efficiency. Therefore, an improved technology is urgently needed to address this problem in the existing technology. Utility Model Content

[0005] The purpose of this invention is to provide a high-silica glass fiber acid-leaching treatment tube. High-silica yarn can be directly wound through this tube. The acid-washed high-silica yarn can have a longer storage and processing cycle. The storage of semi-finished products is conducive to the adjustment and change of production plans. At the same time, the acid-washing agent is sprayed from the inside to the outside through the through groove of the tube, thereby applying pressure to the high-silica yarn and improving the contact between the acid-washing agent and the high-silica yarn, thereby improving the effect and efficiency of acid treatment, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-silica glass fiber acid-asphalt treated tube, comprising a tube body, a base plate and an insertion port, wherein the tube body is a cylindrical structure with openings at both ends, a base plate is provided at one end of the tube body, an insertion port is provided at the other end of the tube body, a rib is provided on the outer edge of the tube body at the insertion port end, and through grooves are symmetrically opened on both sides of the tube body.

[0024] Please see Figure 1-5This utility model provides a technical solution: a high-silica glass fiber acid asphalt treatment tube, including a tube body 1, a base plate 2 and an insertion interface 3. The tube body 1 is a cylindrical structure with open ends. The base plate 2 is provided at one end of the tube body 1. The tube body 1 and the base plate 2 are integral structures to achieve integral molding, which facilitates production and processing. The insertion interface 3 is provided at the other end of the tube body 1. The outer diameter of the insertion interface 3 gradually decreases from the direction close to the tube body 1 to the direction far away from the tube body 1. The outer diameter of the insertion interface 3 at the end close to the tube body 1 is consistent with the inner diameter of the tube body 1, so that when two tubes are inserted into each other, the insertion interface 3 of one tube can be smoothly inserted into the tube body 1 of the other tube body. The outer edge of the tube body 1 at the insertion interface 3 is provided with a rib 4. The tube body 1 is provided with through grooves 5 symmetrically on both sides.

[0025] like Figure 2 As shown, the chassis 2 includes an annular plate 201, an outer ring 202, an inner ring 203, and a reinforcing plate 204. The annular plate 201 is connected to one end of the cylinder 1. An outer ring 202 is provided on the periphery of the end of the annular plate 201 away from the cylinder 1. An inner ring 203 is also provided on the end of the annular plate away from the cylinder 1. The inner ring 203 and the outer ring 202 are located on the same axis. The inner diameter of the inner ring 203 is not less than the inner diameter of the cylinder 1 to ensure that the pickling agent can pass smoothly through the inner ring 203 and into the cylinder 1. The inner wall of the inner ring 203 is provided with an annular groove 205 along the circumferential direction. An annular extension groove 206 is also provided at the end of the annular groove 205 near the cylinder 1. A sealing gasket 6 is provided in the annular extension groove 206. The sealing gasket 6 can ensure the sealing performance whether the two tubes are inserted or connected to the acid inlet at the bottom of the acid tank. The annular groove matches the rib 4. The outer ring 202 and the inner ring 203 are flush with each other at the ends away from the cylinder 1 to ensure connection with the acid outlet at the bottom of the acid tank.

[0026] Usage and Principle: The bobbin 1 and the base 2 are integrally formed and made of PP. The usage method is as follows: Untwisted sodium silicate glass fiber precursor is prepared from powder through a one-step drawing process in a tank furnace. After the drawn yarn is stored, it enters the untwisting and winding process. The untwisted continuous yarn is untwisted to form untwisted continuous yarn. The untwisted yarn is wound onto the bobbin 1 using a winding equipment. The continuous bobbin yarn is then immersed in a specially designed acid tank for acid treatment. The inlet at the bottom of the acid tank is inserted into the inner ring 203 of the base 2 at the bottom of the bobbin 1 (before use, press the sealing gasket 6 into the annular extension groove 206 to ensure a tight seal). The top of the acid tank is stably connected to the insertion interface 3 via a top bracket. The pickling agent enters the bobbin 1 through the inner ring 203 at the bottom and directly contacts the untwisted yarn through various through-grooves 5 of the bobbin 1, producing a high-silica continuous bobbin yarn with a SiO2 content greater than 96%. Next, the high-silica continuous bobbin yarn is washed in a washing machine. The pH value of the yarn surface is measured to be greater than 6, at which point the washing is finished. When using a large-volume acid tank or when the untwisted yarn is long, two bobbins can be spliced ​​together. Specifically, the insertion port 3 of the first bobbin is inserted into one end of the base plate 2 of the second bobbin, so that the rib 4 of the first bobbin is inserted into the annular groove 205 of the inner ring 203 of the second bobbin, thus splicing the two bobbins. Figure 6 As shown, the sealing gasket 6 ensures the sealing of the connection between the two tubes. Then, the untwisted yarn is wound around the outside of the two copper tubes' bodies 1, followed by acid treatment. This utility model has a reasonable structure. High-silica yarn can be directly wound through the tubes. The raw yarn coated with acid can be used for large rolls of high-efficiency warp beams and fabrics, improving the utilization rate of continuous fibers and fabrics, thereby reducing production and transportation costs. The high-silica yarn after acid washing can have a longer storage and processing cycle. The storage of semi-finished products (yarn) is conducive to production plan adjustments and changes. At the same time, the acid coating is sprayed from the inside to the outside through the through groove 5 of the tube, thereby applying pressure to the high-silica yarn, improving the contact between the acid coating and the high-silica yarn, thereby improving the effect and efficiency of acid treatment. Furthermore, a rib 4 is provided at one end of the tube 1, and an annular groove 205 is opened on the inner wall of the inner ring 203 of the base 2. When the high-silica yarn is long or the acid tube is high, the two tubes can be inserted into each other, greatly improving flexibility and applicability.
