[0002] High-temperature treatment of quartz sand is a key step in the production of ultra-pure quartz sand. This is because many purification steps are carried out in water, requiring high-temperature drying to obtain finished quartz sand. Furthermore, quartz crystals contain a certain amount of lattice element impurities and fluid inclusions, which can only be removed through high-temperature gasification or high-temperature decomposition techniques. After high-temperature treatment, the ultra-pure quartz sand must be cooled in a pollution-free manner to obtain the finished product.

[0003] There are also related technologies for quartz sand cooling, such as:

A quartz sand high-temperature treatment water cooling device and treatment method with publication number CN117824287A mainly adds the high-temperature treated quartz sand into an inclined and rotating quartz cooling tube, and cools the quartz sand in the cooling tube by spraying water outside the quartz cooling tube.

[0005] 2. A quartz sand cooling device with publication number CN219656440U mainly adds quartz sand into a cooling barrel, sets water cooling and air cooling devices on the inner wall of the cooling barrel, and utilizes a stirring device in the cooling barrel to uniformly cool the quartz sand.

[0006] 3. A cooling device for quartz sand with publication number CN219433601U mainly adds quartz sand into a conveying cylinder and conveys the quartz sand forward through spiral blades. During the conveying process, water cooling and air cooling devices are set outside the conveying cylinder to cool the quartz sand in the conveying cylinder.

[0007] 4. A high-purity quartz sand cooling device with publication number CN217900246U mainly utilizes wind to cool the high-purity quartz sand rotating in a rotating trough.

[0008] 5. A device for improving the cooling efficiency of quartz sand with publication number CN215177075U mainly sets a cooling device outside the cooling device body and uses a stirring device to stir the quartz sand in the cooling device body so that the quartz sand contacts and cools the outer wall of the cooling device body.

[0009] 6. The stepped quartz sand particle cooling machine with publication number CN215002529U and the cylindrical quartz sand particle cooling machine with publication number CN215176447U mainly use water to cool the quartz sand in the stepped cooling box or the connecting pipe in the cylinder.

[0010] 7. A cooling device for high-temperature quartz sand with publication number CN204115521U mainly utilizes water to cool the quartz sand in a distribution trough.

[0011] However, among the aforementioned prior art, only one type of high-temperature quartz sand water-cooling device and method disclosed is suitable for cooling ultra-pure (high-purity) quartz sand. Other materials used do not meet the cooling requirements for ultra-pure (high-purity) quartz sand. Furthermore, this technology cannot completely prevent contamination of the high-temperature ultra-pure quartz sand by the surrounding environment during the cooling process. Therefore, the development of a high-temperature ultra-pure quartz sand cooling device is of great significance. Utility Model Content

After the exhaust gas treatment tank 58 is completed, cooling water is added to the exhaust tank 581 until the cooling water level 582 is 300mm away from the top of the exhaust tank 581. In this way, the outlet end of the exhaust gas intake pipe 583 is located 500mm below the cooling water level 582; the intake hose 54 and the outlet hose 59 Fluoroplastic hoses are used, and as a preferred option, this embodiment uses polytetrafluoroethylene hoses as the inlet hose 54 and outlet hose 59. The inlet hose 54 connects the ultra-clean gas tank 53 with a valve and flow meter to the inlet pipe 52. The outlet hose 59 connects the outlet pipe 57 to the waste gas inlet pipe 583 of the waste gas treatment tank 58. After the waste gas flows out of the outlet pipe 57, it passes through the outlet hose 59 and the waste gas inlet pipe 583 of the waste gas treatment tank 58 and enters the waste gas tank 581. After being cooled and treated by the cooling water in the waste gas tank 581, it is discharged through the exhaust pipe 584.

[0048] After the high-temperature, ultrapure quartz sand cooling device is fabricated, the packaging unit 31 of the ultrapure quartz sand discharging device 3 is installed within the discharge baffle tube 24 of the quartz sand cooling tube device 2, completing the fabrication and assembly of the high-temperature, ultrapure quartz sand cooling device. The high-temperature, ultrapure quartz sand is then cooled.

[0049] First consider the usage characteristics of various cooling media.

[0050] The cooling medium in the cooling water pipe assembly 4 is water. There are two sources for cooling water: tap water or water stored in a water tank. The water in the water tank can be recycled water from production or circulating cooling water. The present invention preferably uses recycled water from production stored in the water tank as the cooling medium. Furthermore, to prevent damage to the quartz glass tube equipment caused by excessive pressure from the water pump supplying water to the cooling water pipe assembly 4, the water tank is elevated in this embodiment, allowing the recycled water in the tank to flow directly into the cooling water pipe assembly 4. This significantly reduces water consumption and lowers production costs. Based on the above analysis, in this embodiment, the water storage tank for storing recycled production water will be raised to 4500 mm so that the recycled water in the water storage tank can be supplied to the cooling water pipe device 4 by gravity under the action of the static water pressure generated by the height difference; in this embodiment, an outlet pipe will be set near the bottom of the water storage tank, and a valve and a flow meter will be set on the outlet pipe, so that the water storage tank for storing recycled water will become a cooling water source 43 with a valve and a flow meter. Finally, the outlet pipe of the water storage tank is connected to the inlet pipe 42 using an inlet hose 44 to complete the production and assembly of the cooling water pipe device 4.

[0051] In the cooling air pipe device 5, the cooling medium is ultra-clean gas. There are two types of ultra-clean gas. One is the ultra-clean gas obtained by liquefying air, such as ultra-clean nitrogen (N2), ultra-clean oxygen (O2), etc., and the other is ultra-clean air, that is, the purified air is directly used as the cooling medium; as a preferred embodiment, the utility model uses purified air as the cooling medium in the cooling air pipe device 5, so that the purified air buffer tank with a valve and a flow meter is used as the ultra-clean gas tank 53 with a valve and a flow meter in this embodiment, and the purified air buffer tank with a valve and a flow meter is connected to the air inlet pipe 52 using an air inlet hose 54 to complete the production and assembly of the cooling air pipe device 5.

[0052] After the above supporting work is completed, the specific operations of this embodiment begin.

[0053] First, start the cooling water pipe assembly 4. Open the valve of the cooling water source 43, which has a valve and flow meter, and adjust the valve opening to achieve a cooling water flow rate of 10 m³ / hour. After the valve is opened, cooling water flows through the water inlet hose 44 and the water inlet pipe 42 into the water storage pipe 41. Once the cooling water fills the water storage pipe 41, the cooling pipe 21 of the quartz sand cooling pipe assembly 2 is immersed in the cooling water. As the cooling water continues to flow in, the cooling water continuously flows out of the water outlet pipe 45 above the water storage pipe 41 and into the wastewater tank 46 through the water outlet hose 47.

[0054] Then, start the cooling gas pipe device 5. Open the valve of the ultra-clean gas tank 53 (the buffer tank for purified air) with a valve and flowmeter, and adjust the valve opening degree so that the ultra-clean gas flow rate reaches 60m³ / hour. After the valve is opened, the ultra-clean gas is injected into the gas storage pipe 51 through the gas inlet hose 54 and the gas inlet pipe 52, and then flows into the cooling pipe 21 of the quartz sand cooling pipe device 2 through the gas inlet hole 55 on the gas storage pipe 51. As the ultra-clean gas is continuously injected, the cooling pipe 21 is filled with ultra-clean gas. When the ultra-clean gas in the cooling pipe 21 reaches a certain amount or a certain pressure, the ultra-clean gas will escape from the gas outlet pipe 57 at the top of the cooling pipe 21 and the discharge pipe 23 at the bottom of the cooling pipe 21 (when the discharge controller is turned on). However, when the cooling pipe 21 is filled with high-temperature ultra-pure quartz sand, the hot ultra-pure gas (exhaust gas) will be discharged mainly from the gas outlet pipe 57 at the top of the cooling pipe 21, and will not be discharged from the discharge pipe 23 at the bottom of the cooling pipe 21. 3 escapes, which is mainly due to the following reasons: on the one hand, the heat energy emitted by the high-temperature ultrapure quartz sand has the characteristic of migrating upward, which drives the heated ultrapure gas to migrate upward, so that the hot ultrapure gas is mainly discharged from the outlet pipe 57 at the top of the cooling pipe 21; on the other hand, after being discharged through the outlet pipe 57, the hot ultrapure gas (exhaust gas) is injected into the cooling water in the exhaust tank 581 through the outlet hose 59 and the exhaust gas inlet pipe 583 of the exhaust gas treatment tank 58. After cooling, the hot ultrapure gas (exhaust gas) shrinks in volume, thereby causing a slight negative pressure to be generated in the exhaust gas inlet pipe 583, the outlet hose 59 and the outlet pipe 57 of the exhaust gas treatment tank 58. The negative pressure is conducive to the hot gas in the cooling pipe 21 to flow to the exhaust gas treatment tank 58; the ultrapure gas discharged from the outlet pipe 57 is cooled and treated by the cooling water in the exhaust tank 581, and then discharged through the exhaust pipe 584 at the top of the exhaust tank 581.

[0055] Finally, the high-temperature ultrapure quartz sand begins to cool. Close the discharge controller 25 of the quartz sand cooling tube device 2, open the high-temperature quartz sand feeding device 1, and allow the high-temperature ultrapure quartz sand to flow through the discharge pipe of the high-temperature ultrapure quartz sand feeding device 1 into the feed pipe 22 of the quartz sand cooling tube device 2, and finally into the cooling tube 21. The high-temperature ultrapure quartz sand is cooled doubly in the cooling tube 21: indirect cooling from the flowing water in the water storage pipe 41 (cooling water pipe device 4) outside the cooling tube 21, and direct cooling from the ultrapure gas in the gas storage pipe 51 (cooling gas pipe device 5) inside the cooling tube 21. As the high-temperature ultrapure quartz sand in the cooling tube 21 continues to increase, the ultrapure gas in the cooling tube 21 directly exchanges heat with the high-temperature quartz sand and is continuously heated. Under the action of heat energy and gas pressure, the hot ultrapure gas (exhaust gas) is continuously discharged from the outlet at the top of the cooling tube 21. Tube 57 discharges and takes away a large amount of heat from the high-temperature ultra-pure quartz sand; the cooling water that continuously flows from bottom to top in the water storage pipe 41 outside the cooling tube 21 also takes away a large amount of heat from the high-temperature ultra-pure quartz sand transferred from the cooling tube 21; therefore, when the cooling tube 21 is filled with high-temperature ultra-pure quartz sand, the high-temperature ultra-pure quartz sand added in the early stage and located at the lower part of the cooling tube 21 has achieved the expected cooling effect under the double cooling effect. At this time, the discharge controller 25 at the bottom of the cooling tube 21 can be slowly opened to allow the cooled ultra-pure quartz sand to flow into the packaging equipment 31 of the ultra-pure quartz sand discharging device 3. The cooling effect is judged according to the temperature of the ultra-pure quartz sand in the packaging equipment 31, and the temperature of the ultra-pure quartz sand continuously flowing into the packaging equipment 31 is kept within an appropriate range by adjusting the degree of opening of the discharge controller 25. In this embodiment, by adjusting the opening degree of the discharge controller 25, when the output of the cooling process is about 200 kg / h, the temperature of the ultrapure quartz sand flowing into the packaging equipment 31 is in the range of 35°C-40°C, achieving the expected cooling effect.

[0056] Example 2:

[0057] The same cooling technology and device as those in Example 1 are used, and the various parameters of the high-temperature ultrapure quartz sand to be cooled are also the same as those in Example 1. The difference from Example 1 is the cooling water flow rate and the cooling air flow rate. Compared with Example 1, the cooling water flow rate in this embodiment is reduced from 10 m³ / hour to 5 m³ / hour, and the cooling air flow rate is reduced from 60 m³ / hour to 30 m³ / hour. Under this condition, the high-temperature ultrapure quartz sand is cooled.

[0058] The same operating process as in Example 1 was employed, except that the cooling water flow rate was adjusted to 5 m³ / hour when the cooling water pipe device 4 was activated, and the ultra-clean gas flow rate was adjusted to 30 m³ / hour when the cooling gas pipe device 5 was activated. After the cooling pipe 21 of the quartz sand cooling pipe device 2 was filled with high-temperature ultra-pure quartz sand, the discharge controller 25 was activated and adjusted to maintain the temperature of the ultra-pure quartz sand flowing into the packaging equipment 31 within a range of 35°C-40°C. Testing showed that the cooling process output at this point was approximately 110 kg / hour.

[0059] The utility model provides a high-temperature ultrapure quartz sand cooling device. By implementing a process combining water cooling and air cooling, the high-temperature ultrapure quartz sand can be cooled quickly and pollution-free. Under the condition that the equipment parameters are fixed, the cooling effect and the output of ultrapure quartz sand can be controlled by adjusting the cooling water flow rate and the cooling air flow rate. In particular, the utility model adopts ultra-clean gas to directly cool the high-temperature ultrapure quartz sand, which not only improves the cooling efficiency, but also the ultra-clean gas has an air-sealing effect, which can prevent pollutants in the surrounding environment (such as unpurified air) from entering the cooling device of the high-temperature ultrapure quartz sand, thereby eliminating the environmental pollution factors in the existing high-temperature ultrapure quartz sand cooling technology.
