Description

Technical Field

[0001] The present invention relates to the technical field of basalt fiber preparation, and in particular to a method and equipment for preparing homogenized raw materials for high-modulus basalt fiber. Background Art

[0002] Basalt fiber is purely natural, has a harmless production process, and has a long product life. It is a new type of green, active and environmentally friendly material with low cost, high performance, and ideal cleanliness. It has many excellent properties, such as high strength, high quality, corrosion resistance, oxidation resistance, and electrical insulation, and is widely used in various fields.

[0003] Homogenized raw materials for basalt fiber refer to basalt raw materials that have been treated by physical, chemical or process means to make their composition, particle size and microstructure reach a highly uniform state to meet the component stability requirements of high modulus fiber production.

[0004] At present, in the preparation process of basalt fiber homogenization raw materials, when crushing basalt, traditional crushing processes (such as jaw crushing + ball milling) are difficult to achieve effective dissociation of mineral phases, especially the interbedded structure of ferromagnesian minerals (such as pyroxene and olivine) and aluminosilicates, which makes it difficult to achieve a higher uniform dispersion, which may lead to fluctuations in microscopic components in the melt; secondly, the conventional pickling process is prone to reaction blind spots, and the pickling process has a low removal rate of sulfides. The residual sulfur element is prone to form SO2 bubbles when melted at high temperature, which may cause internal defects in the fiber and deteriorate the high-temperature performance of the fiber.

DETAILED DESCRIPTION

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0045] Example:

[0046] like Figure 1-6 As shown, an embodiment of the present invention provides a method for preparing a homogenized raw material of high modulus basalt fiber, comprising the following steps:

[0047] S1. The raw materials are crushed by the crushing mechanism and then separated by air flow to obtain the main raw materials;

[0048] S2. Add a grain refiner and a melt viscosity modifier into the crushing mechanism and mix them with the main raw materials. The grain refiner is nano-CeO2, added in an amount of 0.1-0.5wt%, and the melt viscosity modifier is magnesite powder, added in an amount of 1-3wt%;

[0049] S3. The main raw material is washed under acidic conditions, using full steam pickling, treated with 15wt% H2SO4 solution at 120℃, with a liquid-to-solid ratio of 3:1. The impurities after pickling are removed through three stages of separation: cyclone separator to remove solid residue; condensation-alkali washing combined to remove SO2 gas; sulfide precipitation method to extract soluble Fe 2+ ;

[0050] S4. The treated raw material after acid washing is stirred with 8-12 wt% NaOH solution at 80-90°C to remove impurities, and then washed and dried. The impurity separation after alkali washing includes: removing unreacted mineral particles with a spiral centrifuge; passing CO2 gas to precipitate Al(OH)3 / Fe(OH)3; and filtering with a ceramic membrane to obtain a high-purity sodium silicate solution.

[0051] S5. The dried main raw material is fed into a melting furnace, melted at 1500-1550°C and introduced with Mg vapor generated by the decomposition of MgCl2. The melt is homogenized by a stirring compound action;

[0052] S6, basalt melt enters two temperature control zones, the initial temperature control zone is for coarse adjustment of melt temperature, and the forming zone temperature control zone is for fine adjustment of melt temperature. The initial temperature control zone is 1400-1450℃, and the forming zone temperature control zone is 1350℃±5℃;

[0053] S7. After the melt is temperature-controlled in the dual temperature control zones, it is rapidly cooled into an amorphous thin ribbon by a water-cooled copper roller with micro grooves on its surface. The melt is crushed into 0.5-2mm glass material in a liquid nitrogen environment.

[0054] When selecting raw materials, factors such as basalt purity and availability must be considered. Suitable basalt should contain high-quality silicates and sufficient basalt melting capacity. Basalt ore is fed into the interior of the fixed drum 2 through the hopper 24. The rotating disk 4 and crushing rollers inside the fixed drum 2 crush the basalt ore to a particle size of ≤50μm. The light components are separated by the pressure blast 20 and the airflow of the filter drum 2 as the main raw material.

[0055] While the basalt ore is being crushed inside the fixed cylinder 2 , 0.3 wt % nano CeO 2 and 2 wt % magnesia powder are simultaneously added through another hopper 24 and dry-mixed with the main raw material inside the fixed cylinder 2 .

[0056] Second, in the pickling reaction stage, full steam pickling is adopted, using 15wt% H2SO4 solution to spray the basalt raw materials in a high-temperature steam environment at 120℃. After the reaction, FeS2 is decomposed into soluble Fe 2+ , SO42- and a small amount of elemental sulfur (S) and SO2 gas.

[0057] A cyclone separator is set at the bottom of the pickling tower. The slurry after pickling enters the cyclone separator and rotates at high speed. The unreacted ore particles and elemental sulfur are thrown to the wall of the device due to centrifugal force and fall into the waste slag collection tank.

[0058] The mixed gas (containing H2SO4 vapor and SO2) discharged from the top of the pickling tower enters the condensing tower, the H2SO4 vapor is condensed into liquid and returned to the pickling tank, and the remaining SO2 gas is passed into the Venturi washing tower, reacting with 8wt% NaOH solution to generate Na2SO3. The tail gas is adsorbed by activated carbon and then discharged in compliance with the emission standards.

[0059] The pickling liquid is pumped into the reactor and Na2S solution and Fe 2+ FeS precipitate is generated, the mixed liquid is separated by a filter press, the FeS filter residue is treated as hazardous waste, and the filtrate enters a vacuum distillation tower to recover H2SO4.

[0060] 3. After pickling, the raw materials were stirred with 10wt% NaOH solution (liquid-to-solid ratio 5:1) at 85°C for 1.5 hours. The products included soluble NaAlO2, Na2SiO3 and a small amount of NaFeO2, and undissolved impurities (SiO2, Mg(OH)2, etc.).

[0061] After alkali washing, the slurry is centrifuged and the unreacted mineral particles (such as quartz and corundum) are thrown to the drum wall and discharged through a screw conveyor;

[0062] CO2 gas was introduced into the centrifuged supernatant, the pH was adjusted to 10-11, and 0.1 wt% polyacrylamide (PAM) flocculant was added to promote the growth of Al(OH)3 / Fe(OH)3 flocs;

[0063] After precipitation, the slurry is filtered at a pressure of 0.4 MPa. The filtrate is a pure Na2SiO3 solution (SiO2 content ≥ 98%). The filter residue (Al(OH)3 / Fe(OH)3 mixture) is dehydrated by a filter press and recovered as a by-product.

[0064] Washing: The solid residue after centrifugation is washed with 60°C deionized water in a countercurrent manner to remove residual alkali on the surface;

[0065] Drying: The raw materials were dried in a pulse airflow drying tower (inlet temperature 200°C, outlet temperature 80°C).

[0066] 4. The dried raw materials are fed into a gas melting furnace and melted at 1520°C. Mg vapor generated by MgCl2 (decomposed at 600°C) is introduced at the same time. The melt is homogenized with a molybdenum alloy stirring paddle for 2 hours.

[0067] 5. The basalt melt enters two temperature control zones, and the melt temperature is adjusted to the wire drawing forming temperature of about 1350℃. The initial temperature control zone is used for "rough" adjustment of the melt temperature, and the forming zone temperature control zone is used for "fine" adjustment of the melt temperature.

[0068] 6. The melt flows out through the platinum plate and passes through a water-cooled copper roller with micro grooves on the surface (cooling rate 10 5 The amorphous ribbon was quenched at 1000 K / s to form a 30 μm thick amorphous ribbon. The ribbon was then crushed into 1 mm ± 0.5 mm glass frit in a liquid nitrogen environment.

[0069] A homogenized raw material preparation device for high modulus basalt fiber, the crushing mechanism includes a base plate 1, a fixed cylinder 2 is fixedly provided on the top of the base plate 1, a first rotating shaft 3 is rotatably connected inside the base plate 1, a turntable 4 is fixedly provided on the top of the turntable 4, a fixed column 7 is fixedly provided on the top of the fixed column 7, a top plate 8 is fixedly provided on the top of the filter cylinder 9, a plurality of second rotating shafts 5 are uniformly connected to the inside of the fixed cylinder 2 and on one side near the bottom, a crushing roller 6 arranged near the edge of the turntable 4 is fixed at one end of the second rotating shaft 5, a first gear 13 is fixed at the other end of the second rotating shaft 5, a driving assembly is provided on the side of the fixed cylinder 2 near the bottom, and the driving assembly is used to drive the first rotating shaft 3 and the first gear 13 to rotate synchronously.

[0070] The basalt material falls onto turntable 4, which rotates. Centrifugal force causes the basalt to spread outward and be crushed by rotating crushing rollers 6. Fine particles rise with the airflow and pass through the sieve holes of filter drum 9. Coarse particles are further crushed by centrifugal force, material-to-material collisions, and collisions with the inner wall of fixed drum 2. The rotating structure of filter drum 9 also reduces the accumulation of fine particles and the sieve hole clogging rate.

[0071] The driving assembly includes a third rotating shaft 16 rotating inside the base plate 1, a first motor 19 provided at the bottom end of the third rotating shaft 16, a second gear 17 fixed to the top of the third rotating shaft 16, a rotating ring 11 rotating on the top of the base plate 1, a fixed ring 12 fixed to one side of the rotating ring 11, a second ring gear 15 fixed to the top of the fixed ring 12, a first ring gear 14 fixed to one side of the fixed ring 12 and two pulleys 18, the bottom end of the third rotating shaft 16 is fixedly connected to the output shaft of the first motor 19, the first gear 13 is meshed with the second ring gear 15, the second gear 17 is meshed with the first ring gear 14, and the two pulleys 18 are respectively fixed on the third rotating shaft 16 and the first rotating shaft 3, and the two pulleys 18 are connected by belt transmission.

[0072] When first motor 19 is activated, its output shaft rotates third shaft 16. This, in turn, drives fixed ring 12 through the meshing of second gear 17 and first ring gear 14. Simultaneously, pulley 18 synchronizes the rotation of first shaft 3, driving the integrated rotation of turntable 4 and filter cartridge 9. Second ring gear 15 rotates in unison with fixed ring 12. Engaging with first gear 13, it drives second shaft 5 and its associated crushing roller 6 to rotate, shearing and crushing the basalt ore at high speeds.

[0073] Two feeding assemblies are symmetrically positioned near the top of the fixed barrel 2. One feeding assembly is used to add basalt raw material, and the other is used to add grain refiners and melt viscosity modifiers. The feeding assemblies include a feed pipe 21 fixed within the fixed barrel 2, a feed barrel 22 mounted at the top of the feed pipe 21, a fourth rotating shaft 25 rotating within the feed barrel 22, a second motor 23 fixed to the outside of the feed barrel 22, a plurality of partition plates 26 uniformly fixed to the outside of the fourth rotating shaft 25, a hopper 24 mounted at the top of the feed barrel 22, and two connecting hoppers 27. A feeding area is formed between the partition plates 26, which slide against the inner wall of the feed barrel 22 to seal the fixed barrel 2. One end of the fourth rotating shaft 25 is fixedly connected to the output shaft of the second motor 23. The two connecting hoppers 27 are fixedly connected between the top of the feed barrel 22 and the hopper 24, and between the bottom of the feed barrel 22 and the feed pipe 21, respectively.

[0074] Basalt ore is loaded into one side hopper 24, which also contains a premix of nano-CeO2 and magnesia borax powder. The second motor 23 is turned on, driving the fourth rotating shaft 25 to rotate. The separator 26 pushes the basalt and additives through the connecting hopper 27 to the feed pipe 21, where they fall onto the turntable 4.

[0075] The top of the filter cartridge 9 is designed as a conical structure and is fixed with a connecting pipe 10. The connecting pipe 10 rotates inside the top side of the fixed cartridge 2. A delivery pipe 28 is installed on the top of the fixed cartridge 2. A pressure blower 20 is fixed to one end of the delivery pipe 28. The top end of the delivery connecting pipe 10 rotates inside the delivery pipe 28. The rotational seal between the connecting pipe 10 and the fixed cartridge 2 and the delivery pipe 28 is sealed with an elastomeric rotary seal for adaptive sealing. The main raw material in the delivery pipe 28 is transported by the pressure blower 20 for pickling.

[0076] The ground basalt fine particles rise with the air flow under the action of the pressure blower 20. The fine materials that meet the fineness requirements pass through the sieve holes of the rotating filter cylinder 9 and enter the conveying pipe 28 through the connecting pipe 10. The pressure blower 20 blows the materials into the pickling tower with wind pressure.
