Description

Technical Field

[0001] This invention relates to the field of high-purity quartz sand preparation technology, and more particularly to a multi-field synergistic assisted equipment for deep removal of gas-liquid inclusions in high-purity quartz sand. Background Technology

[0002] High-purity quartz sand is mainly used in high-tech industries such as aerospace, bioengineering, high-frequency technology, electronics, fiber optic communication, and military. The limited reserves of quartz sand, coupled with the rapid development of global fiber optic communication and semiconductor industries, are gradually depleting its resources. Only first- and second-grade high-quality crystals in nature can be used to produce high-purity quartz sand. Quartz ore commonly contains gas-liquid inclusions, which are formed during mineral growth by encapsulating impurities within the quartz crystals. The presence of these inclusions directly affects the purity and performance of quartz products.

[0003] Currently, the main processes for reducing impurities in quartz sand include water washing, acid washing, flotation, magnetic separation, and electrostatic separation. These methods can remove most of the external impurities from the quartz sand. For gas-liquid inclusions inside the quartz sand, although high-temperature water quenching and microwave removal techniques exist, these methods are relatively inefficient and ineffective at removing some gas-liquid inclusions. For example, microwave removal is ineffective when the gas-liquid inclusions do not contain substances with high dielectric constants. Therefore, there is an urgent need to develop a highly efficient device for removing gas-liquid inclusions from high-purity quartz sand. Summary of the Invention

[0004] To address the shortcomings of existing methods for deep removal of gas-liquid inclusions in high-purity quartz sand, this invention provides a device that utilizes the synergistic assistance of ultrasonic fields, temperature fields, laser fields, and infrared light fields to efficiently and stably remove gas-liquid inclusion impurities from high-purity quartz sand.

[0005] The technical means employed in this invention are as follows:

[0006] A multi-field synergistic assisted deep removal equipment for gas-liquid inclusions in high-purity quartz sand includes a frame, a worktable mechanism, an ultrasonic vibration table, a loading mechanism, a control system, a laser and infrared light system, a rotary telescopic spindle, and a temperature control system. The worktable mechanism is installed at the bottom of the frame, the ultrasonic vibration table is rotatably connected to the worktable, the loading mechanism is set on the ultrasonic vibration table, the control system is installed on one side of the bed, the laser and infrared system is fixed at the end of the rotary telescopic spindle, the rotary telescopic spindle is installed above the equipment processing chamber through a horizontal partition, and the temperature control system is set on both sides and the rear of the processing chamber.

[0007] Furthermore, the frame includes an outer shell, a processing compartment, a horizontal partition, an electronic component compartment and its door, an internal viewing window, and a processing compartment door. The outer shell is rectangular, and the horizontal partition divides the interior of the outer shell into an electronic component compartment and a processing compartment. The electronic component compartment is used to install the electronic components of the equipment and the motor and hydraulic cylinder of the rotary telescopic spindle. The processing compartment is equipped with a worktable mechanism, an ultrasonic vibration table, a loading mechanism, a laser and infrared system, a rotary telescopic spindle, and a temperature control system.

[0008] Furthermore, the workbench mechanism includes a workbench motor, a workbench, a hinge, and a hydraulic telescopic rod. The workbench motor is mounted on the frame below the workbench. The workbench is cylindrical. The hinge is installed on the front side of the workbench, connecting the workbench and the ultrasonic vibration table. The hydraulic telescopic rod is located inside the workbench and connected to the ultrasonic vibration table. The workbench motor is connected to the hydraulic telescopic rod. Driven by the motor, the hydraulic telescopic rod can lift the ultrasonic vibration table from the rear.

[0009] Furthermore, the ultrasonic vibration table includes a concentrator and vibrators, wherein eight vibrators are evenly arranged inside the ultrasonic vibration table, which can realize ultrasonic vibration of the upper loading hopper, increase the activation energy of gas-liquid inclusions in the quartz sand and cause the quartz sand to rub and collide with each other.

[0010] Furthermore, the loading mechanism includes a loading bin, a bin door, and a bin door track. The bin door is located directly in front of the loading bin, and the bin door track is located on one side of the bin door. The loading bin is used as a processing container for quartz sand. When the bin door is opened, the hydraulic telescopic rod in the workbench mechanism lifts one side of the loading bin mechanism to pour out the processed quartz sand.

[0011] Furthermore, the laser and infrared system includes a laser generator, an infrared generator, and an optical path system. The infrared irradiator is set up in one group, and the laser is set up in two groups according to the intensity: a weak laser and a strong laser. The intensity of the laser can be adjusted. The infrared light assist is used to gradually increase the internal energy of molecules in the quartz sand, and the laser assist is used to instantly increase the internal energy and activation energy of molecules in the quartz sand, so as to achieve particle cracking or even explosion, thereby causing gas-liquid inclusions to overflow.

[0012] Furthermore, the rotary telescopic spindle includes a rotary control motor, a reduction gear set, a hydraulic motor, a hydraulic mechanism, and a hydraulic gear set. Each component is located in the electronic component compartment above the horizontal partition. The rotary control motor controls the spindle rotation through the reduction gear set, and the hydraulic motor controls the spindle extension and retraction through the hydraulic gear set and the hydraulic mechanism. Turning on the rotary motor allows the spindle to rotate, driving the laser and infrared systems to rotate, thus enabling infrared light and lasers of different intensities to uniformly irradiate the quartz sand. Starting the hydraulic pump motor can adjust the extension and retraction length of the spindle, thereby adjusting the illumination distance.

It maintains the quartz sand in a high-energy state through a temperature field, induces collisions and friction between the quartz sand particles through an ultrasonic field to further enhance their internal activation energy, further increases the internal energy of the gas-liquid inclusions through an infrared light field, and then instantaneously excites the quartz sand with a laser field, promoting the internal bursting of the quartz sand containing gas-liquid inclusions. The synergistic effect of multiple fields increases the probability of quartz sand particle bursting, causing the gas-liquid inclusions to escape and achieving deep removal.

[0016] This invention provides a multi-field synergistic assisted equipment for deep removal of gas-liquid inclusions in high-purity quartz sand. By using a multi-field synergistic assistance method, it not only increases the effect of gas-liquid inclusion removal but also improves the removal efficiency, fundamentally achieving the goal of high-quality and high-efficiency deep removal of gas-liquid inclusions in high-purity quartz sand.

[0036] like Figure 1-3 As shown, this invention discloses a multi-field synergistic assisted deep removal equipment for gas-liquid inclusions in high-purity quartz sand. By utilizing the synergistic assistance of ultrasonic field, temperature field, laser field and infrared light field, the equipment can deeply remove gas-liquid inclusions in quartz sand, fundamentally achieving the goal of high-quality and efficient deep removal of gas-liquid inclusions in high-purity quartz sand.

[0037] Specifically, it includes a frame 1, a worktable mechanism 2, an ultrasonic vibration table 3, a loading mechanism 4, a control system 5, a laser and infrared light system 6, a rotary telescopic spindle 7, and a temperature control system 8. The worktable 2-2 is mounted at the bottom of the frame 1, and the ultrasonic vibration table 3 is connected to the worktable 2-2 via hinges 2-3 and hydraulic rods. The loading bin 4-2 is located on the ultrasonic vibration table 3. The control system 5 is mounted on one side of the frame 1. The laser and infrared system 6 is fixed to the end of the rotary telescopic spindle 7, with a preset distance between the bottom of the laser and infrared system 6 and the top of the loading mechanism 4. The rotary telescopic spindle 7 is mounted above the equipment processing chamber 1-2 via a horizontal partition 1-2. The temperature control system 8 is located on both sides and the rear of the processing chamber 1-2.

[0038] The frame 1 includes an outer shell 1-1, a processing compartment 1-2, a horizontal partition 1-3, an electronic component compartment 1-4 and its door 1-5, an inner viewing window 1-6, and a processing compartment door 1-7. The outer shell 1-1 is rectangular and is divided into the processing compartment 1-2 and the electronic component compartment 1-4 by the horizontal partition 1-3. The electronic component compartment 1-4 houses the electronic components of the equipment and the spindle rotation motor 7-1, hydraulic motor 7-5, and hydraulic mechanism 7-3 of the upper rotary telescopic spindle 7. The processing compartment 1-2 houses the worktable mechanism 2, the ultrasonic vibration table 3, the loading mechanism 4, the laser and infrared system 6, the rotary telescopic spindle 7, and the temperature control system 8.

[0039] The workbench mechanism 2 includes a motor 2-1, a workbench 2-2, a hinge 2-3, and a hydraulic telescopic rod. The motor 2-1 is mounted on the frame 1 below the workbench 2-2. The workbench 2-2 is cylindrical. The hinge 2-3 is installed on the front side of the workbench 2-2, connecting the workbench 2-2 and the ultrasonic vibration table 3. The hydraulic telescopic rod is located inside the workbench 2-2, with its input end connected to the motor 2-1 and its output end connected to the ultrasonic vibration table 3. Driven by the motor 2-1, the hydraulic telescopic rod can lift the ultrasonic vibration table 3 from the rear.

[0040] The ultrasonic vibration table 3 includes an ultrasonic transducer 3-1 and an ultrasonic energy concentrator 3-2. Eight ultrasonic transducers 3-1 are evenly arranged inside the ultrasonic vibration table 3, which can realize ultrasonic vibration of the upper loading bin 4-2, increase the activation energy of gas-liquid inclusions in the quartz sand, and cause the quartz sand to rub and collide with each other.

[0041] The loading mechanism 4 includes a loading bin 4-3, a bin door 4-1, and a bin door track 4-2. The bin door 4-1 is located directly in front of the loading bin 4-3, and the bin door track 4-2 is located on one side of the bin door 4-1. The loading bin 4-3 serves as a processing container for quartz sand. When the bin door 4-1 is opened, the hydraulic telescopic rod in the workbench mechanism 2 lifts one side of the loading bin mechanism, allowing the processed quartz sand to be poured out.

[0042] The operating system 5 includes a switch and an operation panel, which can realize the operation of the workbench mechanism 2, ultrasonic vibration table 3, loading mechanism 4, laser and infrared system 5, rotary telescopic spindle 6 and temperature control system 7.

[0043] The laser and infrared system 6 includes an infrared generator 6-1, a weak laser generator 6-2, a strong laser generator 6-4, and an optical path system 6-3. One set of infrared generators 6-1 is provided, and the lasers are configured with weak laser generator 6-2 and strong laser generator 6-4 according to their intensity. The laser intensity of both is adjustable. Infrared light assistance can gradually increase the internal energy of molecules in quartz sand, while laser assistance can instantly increase the internal energy and activation energy of molecules in quartz sand, causing particle cracking or even explosion, thereby releasing gas-liquid inclusions.

[0044] The rotary telescopic spindle 7 includes a rotary control motor 7-1, a reduction gear set 7-2, a hydraulic pump motor 7-5, a hydraulic mechanism 7-3, and a hydraulic gear set 7-4. All components are housed inside the electronic component compartment 1-4 above the horizontal partition 1-3. The rotary control motor 7-1 controls the spindle rotation via the reduction gear set 7-2, while the hydraulic motor 7-5 controls the spindle extension / retraction via the hydraulic gear set 7-4 and the hydraulic mechanism 7-3. Activating the rotary motor 7-1 causes the spindle to rotate, driving the laser and infrared system 6 to rotate, enabling uniform irradiation of the quartz sand by infrared light and lasers of varying intensities. Starting the hydraulic pump motor 7-5 adjusts the spindle extension / retraction length, thereby adjusting the illumination distance.

[0045] The temperature control system 8 can maintain the high energy state of the quartz sand.

[0046] In summary, the multi-energy field synergistic assisted deep removal equipment for gas-liquid inclusions in high-purity quartz sand provided by this invention maintains the quartz sand in a high-energy state through the effect of a temperature field, induces collisions and friction between quartz sand particles through an ultrasonic field to further enhance internal activation energy through an infrared light field, further enhances the internal energy of the gas-liquid inclusions through an infrared light field, and then promotes the internal rupture of quartz sand containing gas-liquid inclusions through a laser field. This multi-field synergistic effect increases the efficiency of quartz sand particle rupture, making it easier for gas-liquid inclusions to escape from the quartz sand, fundamentally achieving the goal of high-quality, high-efficiency, and deep removal of gas-liquid inclusions from high-purity quartz sand.

[0047] The specific application method of this invention is as follows: Step 1: Place the quartz sand to be processed in the loading hopper, close the processing chamber door, turn on the temperature control system, set the processing chamber temperature to 400-800℃, and preheat the quartz sand.

[0048] Step 2: Set the ultrasonic vibration frequency to 50-100kHz, set the infrared light output, set the weak laser output intensity to 0-10mW and the strong laser output intensity to 30-80mW respectively, set the parameters of the rotary telescopic spindle, determine the rotation speed of the laser and infrared system to 0-10r / min and the distance between the laser and infrared system and the quartz sand to 20-100cm, set the processing time to 3-6 hours, and start the first stage of processing;

[0049] Step 3: Add 2 / 5 to 3 / 5 of the volume of deionized water to the cold quenching and cleaning mechanism, set the temperature to 0 to 5°C, cool the deionized water to 0 to 5°C, and maintain it.

[0050] After completing steps 2 and 4, open the processing chamber door and transport the processing platform along the track to the cold extraction and cleaning mechanism. Open the loading chamber door and activate the hydraulic telescopic mechanism inside the processing platform to pour the quartz sand into the cold extraction and cleaning chamber for cold extraction for 30–60 minutes. Simultaneously, set the ultrasonic frequency of the cold quenching and cleaning mechanism to 20–200 kHz and the stirring speed to 20–80 r / min, and begin stirring and cold extraction.

[0051] Step 5: After cold extraction, remove the quartz sand and replace the deionized water in the cleaning chamber with a green and environmentally friendly alkaline washing solution. This alkaline washing solution is non-toxic, harmless, and environmentally friendly, and its components include: deionized water, anhydrous sodium carbonate 50-100 g / L, guanidine carbonate 20-80 g / L, and disodium ethylenediaminetetraacetate 5-15 vol.%. Set the temperature to 200-400℃, the ultrasonic frequency to 20-200 kHz, and the stirring speed to 20-80 r / min. Begin alkaline washing for 5-8 hours.

[0052] Step 6: After alkaline washing is completed, remove the quartz sand and replace the alkaline washing solution in the cleaning chamber with a green and environmentally friendly acid washing solution. The acid washing solution is non-toxic, harmless, and environmentally friendly, and its components include: deionized water, malic acid 100-200g / L, citric acid 80-150g / L, and polyethylene 5-10 vol.%. Set the temperature to 200-400℃, the ultrasonic frequency to 20-200kHz, and the stirring speed to 20-80r / min. Begin acid washing for 5-10 hours.

[0053] Step 7: After pickling, remove the quartz sand, replace the pickling solution in the cleaning chamber with anhydrous ethanol, set the temperature to 20-30℃, the ultrasonic frequency to 20-200kHz, and the stirring speed to 20-80r / min, and start cleaning for 30-60 minutes.

[0054] Step 8: After cleaning, use a blower dryer to dry the product at a temperature of 30-50℃.

[0055] This invention maintains quartz sand in a high-energy state through a temperature field, induces collisions and friction between quartz sand particles through an ultrasonic field, further enhancing the internal activation energy, and further increases the internal energy of gas-liquid inclusions through an infrared light field. A laser field then instantaneously excites the quartz sand, promoting the internal fracturing of quartz sand containing gas-liquid inclusions. Cold quenching further exacerbates the fracturing of the high-temperature quartz sand. The multi-field coupling and cold quenching effects increase the probability of quartz sand particle fracturing, causing gas-liquid inclusions to escape and achieving deep removal.

[0056] The alkaline and acidic washing solutions used in this invention include deionized water, anhydrous sodium carbonate, guanidine carbonate, disodium EDTA, malic acid, citric acid, and polyethylene, all of which are environmentally friendly chemical reagents. Deionized water, being pure and free of impurities, serves as the solvent. Anhydrous sodium carbonate and guanidine carbonate are alkaline reagents used to soften, loosen, and disperse impurities and silicate substances adhering to the surface of quartz sand. Disodium EDTA acts as a surfactant, increasing the activity of the chemical reagents and enhancing the alkaline washing effect. Malic acid and citric acid are acidic reagents used to remove oxides and various ionic impurities from the surface of quartz sand. Polyethylene acts as a wetting agent, increasing the wetting effect of the acidic washing solution on the quartz sand surface, allowing the solution to penetrate the crevices of the quartz sand surface and enhancing the cleaning effect.

[0057] In the cleaning process, this invention controls the temperature field and utilizes the flow field generated by ultrasonic assistance and stirring, combined with the chemical action of alkaline and acidic washing solutions, to form a chemical and multi-field-assisted impurity removal mechanism, effectively achieving deep removal of gas-liquid inclusions encapsulated by quartz sand impurities.

[0086] This invention provides a multi-energy field coupling-assisted method for deep removal of impurities from high-purity quartz sand. Through the action of a temperature field, the quartz sand is kept in a high-energy state. The ultrasonic field induces collisions and friction between the quartz sand particles, further increasing their internal activation energy. The infrared light field further enhances the internal energy of gas-liquid inclusions. A laser field instantaneously excites the quartz sand, promoting the internal fracturing of quartz sand containing gas-liquid inclusions. Cold quenching then further exploding the high-temperature quartz sand. The multi-field coupling and cold quenching effects increase the probability of quartz sand particle fracturing, causing gas-liquid inclusions to escape. Combined with the temperature field and the flow field assisted by ultrasound and stirring, the quartz sand is subjected to alkaline and acid washing, respectively, forming a multi-field assisted chemical field coupling cleaning process that removes impurities, including gas-liquid inclusions, from a deep and efficient level.

[0087] Example Product Application: Impurities in high-purity quartz sand have a significant impact on the quality of high-purity quartz crucibles produced. To verify the effectiveness of this invention in removing impurities from quartz sand, three batches of high-purity quartz sand were selected for direct melting into quartz crucibles and for melting into quartz crucibles after impurity removal using the three embodiments of this invention, respectively. The quality effects were compared, and the results are as follows:

[0092] The surface of the molten quartz crucibles was observed using a microscope. The surface conditions of the quartz crucibles numbered 1-3, which were molten using high-purity quartz sand (without impurity removal using this invention), correspond to those in the appendix of this invention. Figure 4-6 The surface states of the quartz crucibles numbered 4-6, which were melted using high-purity quartz sand after impurities were removed according to the present invention, correspond to the appendix of the present invention. Figure 7-9 It can be clearly seen that compared with the quartz crucibles melted with quartz sand that has not been treated with the present invention to remove impurities, the surface quality of the quartz crucibles melted with quartz sand treated with the present invention to remove impurities is significantly improved. Not only are the number of bubbles reduced, but the size of the bubbles is also reduced.
