Since the gas storage pipe 51 is arranged in the cooling pipe 21 of the quartz sand cooling pipe device 2, this embodiment uses a quartz glass tube with a diameter of 50mm-100mm, a length of 1600mm-3600mm, and a thickness of 3mm-8mm to make the gas storage pipe 51. As a preferred solution, the present invention uses a quartz glass tube with a diameter of 70mm, a length of 2600mm, and a thickness of 5mm to make the gas storage pipe 51. In this embodiment, the gas storage pipe 51 is arranged at the center of the cooling pipe 21 of the quartz sand cooling pipe device 2, and an air inlet hole 551 is arranged on the wall of the gas storage pipe 51, and a conical baffle pipe 56 is arranged outside the air inlet hole 551. The conical baffle pipe 56 is mainly used to prevent the high-temperature ultra-pure quartz sand from entering the gas storage pipe 51 through the air inlet hole 551, and at the same time, the ultra-clean gas can be more evenly injected into the high-temperature ultra-pure quartz sand. Each group of air inlet holes 551 is arranged on the same circumference, and each group has 3-6 holes, with an aperture of 1mm-8mm. The cone angle of the matching conical baffle pipe 56 is 30°-60°, and the upper diameter is the diameter of the gas storage pipe 51. The diameter of the conical baffle tube 56 at the top is 0, and the lower diameter is 80mm-150mm. 3-8 groups of air inlet holes 551 and conical baffle tubes 56 can be set on the air storage tube 51. As an option, the present invention selects 4 air inlet holes 551 in each group, with a hole diameter of 5mm, and the matching conical baffle tube 56 has a cone angle of 60°, an upper diameter of 70mm, and a lower diameter of 120mm. A total of 5 groups of air inlet holes 551 and conical baffle tubes 56 are set on the air storage tube 51. The top combination has an air inlet hole 551 20mm away from the top of the air storage tube 51, and the upper diameter of the conical baffle tube 56 is 0 (i.e. the conical baffle tube 56 is conical), and a combination of an air inlet 551 and a conical baffle tube 56 is provided at intervals of 600 mm downwards; in addition, an air inlet 552 with a diameter of 5 mm is provided on the bottom plate of the air storage tube 51, mainly to blow the ultra-pure quartz sand dust out of the air storage tube 51 through the air inlet 552 under the action of the air flow in case a small amount of ultra-pure quartz sand dust enters the air storage tube 51; the air inlet pipe 52 is provided at the lower part of the air storage tube 51, and passes through the cooling tube 21 and the water storage tube 41 to extend to the outside of the water storage tube 41. The air inlet pipe 52 is selected to have a diameter of 32 mm, a length of 170 mm, and a thickness of 3.5mm quartz glass tube; the air outlet pipe 57 is arranged at the edge of the top plate of the cooling tube 21 of the quartz sand cooling tube device 2, and extends upward through the water storage tube 41 to the outside of the water storage tube 41. In order to prevent the heat of the high-temperature ultra-pure quartz sand from being directly radiated to the air outlet hose 59 connected to the air outlet pipe 57 through the air outlet pipe 57, the air outlet pipe 57 extending to the outside of the water storage tube 41 is bent outward by 90° and extended for a certain length in this embodiment to reduce the influence of heat radiation on the air outlet hose 59. As a preferred solution, the present invention uses two quartz glass tubes with a diameter of 32mm, a length of 80mm, and a thickness of 3.5mm to make the air outlet pipe 57. First, a glass tube is arranged at the edge of the top plate of the cooling tube 21, and extends upward through the water storage tube 41 to the outside of the water storage tube 41, and then a horizontal glass tube is connected to make the air outlet pipe 57; the waste gas treatment tank 58 is made of plastic material, and the waste gas tank 581 uses 2m. 3 -5m 3 PE plastic tank, as a preferred solution, this embodiment uses 5m 3 A PE plastic tank is used as the waste gas tank 581, the air inlet pipe 583 is set at the top edge of the waste gas tank 581, and is made of a PE pipe with a diameter of 32mm and a length of 1000mm. The air inlet pipe 583 is inserted 800mm into the waste gas tank 581, and the exhaust pipe 584 is set at the other side edge of the top of the waste gas tank 581, and is made of a PE pipe with a diameter of 65mm and a length of 100mm. After the waste gas treatment tank 58 is completed, cooling water is added to the waste gas tank 581 until the cooling water liquid level 582 is 300mm away from the top of the waste gas tank 581, so that the air outlet end of the air inlet pipe 583 is located at the cooling water liquid level 5 82 below 500mm; the air inlet hose 54 and the air outlet hose 59 are selected from fluoroplastic hoses. As a preferred option, this embodiment selects polyfluoro hoses as the air inlet hose 54 and the air outlet hose 59. The air inlet hose 54 is used to connect the ultra-clean gas tank 53 with a valve and a flow meter to the air inlet pipe 52, and the air outlet hose 59 is used to connect the air outlet pipe 57 to the air inlet pipe 583 of the waste gas treatment tank 58. After the waste gas flows out from the air outlet pipe 57, it enters the waste gas tank 581 through the air outlet hose 59 and the air inlet pipe 583 of the waste gas treatment tank 58, and is cooled and treated by the cooling water in the waste gas tank 581 before being discharged through the exhaust pipe 584.

[0059] After the processing and manufacturing of the high-temperature ultrapure quartz sand cooling device is completed, the packaging equipment 31 of the ultrapure quartz sand discharging device 3 is set up in the discharging baffle tube 24 of the quartz sand cooling tube device 2 to complete the manufacturing and assembly of the high-temperature ultrapure quartz sand cooling device. Then, the high-temperature ultrapure quartz sand is cooled.

[0060] First consider the usage characteristics of various cooling media.

[0061] In the cooling water pipe device 4, the cooling medium is water, and there are two sources of cooling water, one is to use tap water directly, and the other is to use water in a water tank, and the water in the water tank can be production recycled water or cooling circulating water; as a preferred solution, the present invention uses production recycled water stored in the water tank as the cooling medium, and in order to avoid excessive pressure when the water pump supplies water to the cooling water pipe device 4 and cause damage to the quartz glass tube equipment, the water tank is selected to be raised in this embodiment, so that the recycled water in the water tank directly supplies water to the cooling water pipe device 4 by gravity. This can greatly reduce the consumption of water resources and reduce production costs. According to the above analysis, in this embodiment, the water storage tank for storing production recycled water will be raised to 4500mm, so that the recycled water in the water storage tank can supply water 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, a water outlet pipe will be set at the bottom of the water storage tank, and a valve and a flow meter will be set on the water 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, and finally the water outlet pipe of the water storage tank will be connected to the water inlet pipe 42 by using the water inlet hose 44 to complete the production and assembly of the cooling water pipe device 4.

[0062] 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, directly using the purified air as the cooling medium; as a preferred embodiment, the present invention 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 intake pipe 52 by using an air intake hose 54 to complete the production and assembly of the cooling air pipe device 5.

[0063] After the above supporting work is completed, the specific operation of this embodiment begins.

[0064] First, start the cooling water pipe device 4. Open the valve of the cooling water source 43 with valve and flow meter, and adjust the valve opening degree so that the cooling water flow rate reaches 10m 3 / hour; after the valve is opened, the cooling water flows into the water storage pipe 41 through the water inlet hose 44 and the water inlet pipe 42. After the cooling water fills the water storage pipe 41, the cooling pipe 21 of the quartz sand cooling pipe device 2 is immersed in the cooling water. As the cooling water is continuously injected, the cooling water continuously flows out from the water outlet pipe 45 above the water storage pipe 41 and flows into the waste water tank 46 through the water outlet hose 47.

[0065] Then start the cooling gas pipe device 5. Open the valve of the ultra-clean gas tank 53 (buffer tank for purified air) with a valve and a flow meter, and adjust the opening degree of the valve so that the flow rate of the ultra-clean gas 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 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. With the continuous injection of ultra-clean gas, 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 air 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); but when the cooling pipe 21 is filled with high-temperature ultra-pure quartz sand, the hot ultra-pure gas (waste gas) will mainly be discharged from the gas outlet pipe 57 at the top of the cooling pipe 21, and will not escape from the discharge pipe 23 at the bottom of the cooling pipe 21. This is mainly because: on the one hand, the heat emitted by the high-temperature ultra-pure quartz sand It has the characteristic of moving upward, which will drive the heated ultrapure gas to move upward, so that the hot ultrapure gas is mainly discharged from the outlet pipe 57 at the top of the cooling tube 21; on the other hand, after the hot ultrapure gas (waste gas) is discharged through the outlet pipe 57, it is injected into the cooling water in the waste gas tank 581 through the outlet hose 59 and the inlet pipe 583 of the waste gas treatment tank 58. The hot ultrapure gas (waste gas) will shrink in volume after being cooled, thereby causing a slight negative pressure to be generated in the inlet pipe 583, the outlet hose 59 and the outlet pipe 57 of the waste gas treatment tank 58. The emergence of negative pressure is conducive to the hot gas in the cooling tube 21 to flow to the waste gas treatment tank 58; the ultrapure gas discharged from the outlet pipe 57 is cooled and treated by the cooling water in the waste gas tank 581, and then discharged through the exhaust pipe 584 at the top of the waste gas tank 581.

[0066] Finally, the high-temperature ultrapure quartz sand is cooled. The discharge controller 25 of the quartz sand cooling tube device 2 is turned off, and the high-temperature quartz sand feeding device 1 is turned on, so that the high-temperature ultrapure quartz sand flows into the feeding pipe 22 of the quartz sand cooling tube device 2 through the discharge pipe of the high-temperature ultrapure quartz sand feeding device 1, and finally flows into the cooling tube 21. The high-temperature ultrapure quartz sand is subjected to double cooling 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 (waste 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 of the high-temperature ultrapure 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 of the high-temperature ultrapure quartz sand transmitted by the cooling tube 21; therefore, when the cooling tube 21 is filled with high-temperature ultrapure quartz sand, the high-temperature ultrapure 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 ultrapure quartz sand to flow into the packaging equipment 31 of the ultrapure quartz sand discharge device 3. The cooling effect is judged according to the temperature of the ultrapure quartz sand in the packaging equipment 31, and the temperature of the ultrapure 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 / hour, 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.

[0067] Embodiment 2:

[0068] The cooling technology and device are exactly the same as those in Example 1. The 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 increased from 10m 3 / hour reduced to 5m 3 / hour, cooling air flow rate is 60m 3 / hour reduced to 30m 3 / hour, under this condition, the high temperature ultrapure quartz sand is cooled.

[0069] The same operation process as in the first embodiment is adopted, except that when the cooling water pipe device 4 is started, the cooling water flow rate is adjusted to 5m 3 / hour, in addition, when starting the cooling gas pipe device 5, the ultra-clean gas flow rate is adjusted to 30m3 When the cooling tube 21 of the quartz sand cooling tube device 2 is filled with high-temperature ultrapure quartz sand, the discharge controller 25 is turned on, and the temperature of the ultrapure quartz sand flowing into the packaging equipment 31 is adjusted to be in the range of 35°C-40°C by adjusting the opening degree of the discharge controller 25. According to the detection, the output of the cooling process is about 110 kg / hour at this time.

[0070] The present invention provides a high-temperature ultrapure quartz sand cooling device and a cooling method. By implementing a process combining water cooling and air cooling, the high-temperature ultrapure quartz sand can be cooled quickly and pollution-free. When 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 present invention uses 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 a gas 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, eliminating the environmental pollution factors in the existing high-temperature ultrapure quartz sand cooling technology.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
