Description
Technical Field
[0001] This invention relates to the field of quartz sand production technology, specifically to a high-efficiency and environmentally friendly production line for high-purity quartz sand. Background Technology
[0002] Quartz is a non-metallic mineral, a hard, wear-resistant, and chemically stable silicate mineral. Quartz sand is also an important industrial mineral raw material, a non-hazardous chemical, and is widely used in glass, casting, ceramics and fireproof materials, ferrosilicon smelting, metallurgical flux, metallurgy, construction, chemicals, plastics, rubber, abrasives, filter media, and other industries. Quartz sand is produced by crushing quartz stone in a crusher, then screening it in a screening machine, and finally removing impurities. However, quartz sand contains soil, iron filings, and light impurities, which can lead to substandard quality and serious economic losses when used. Therefore, in the quartz sand production line, the produced quartz sand must be cleaned and impurities removed before use.
[0003] Existing production lines remove soil from quartz sand by sampling and washing it. However, some stubborn soil adhering to the surface of the quartz sand is difficult to clean completely. Furthermore, the lines cannot effectively remove iron filings and light impurities, resulting in poor-quality quartz sand. Additionally, the washed quartz sand needs to be manually discharged during production before being fed into a dryer. This leads to poor integration within the production line, resulting in low production efficiency. The low energy consumption during drying also contributes to poor energy conservation, while the excessive dust generated causes environmental pollution. Summary of the Invention

[0032] Example 1
[0033] Please see Figures 1-9As shown, this invention is a high-efficiency and environmentally friendly production line for high-purity quartz sand, including an installation platform 1. A screening machine 2 is fixedly connected to the top of the installation platform 1, and a crusher 3 is fixedly connected to the top of the screening machine 2.

The quartz sand raw material is crushed by the crusher 3, and the crushed raw material is screened by the screening machine 2. The qualified quartz sand is fed into the water washing and drying integrated machine through the elevator 4. Subsequently, the water washing and drying integrated machine quickly and thoroughly washes and dries the quartz sand, cleaning away the mud and impurities in the quartz sand, greatly improving the quality of the produced quartz sand, and also improving the production efficiency of quartz sand.
[0034] Example 2
[0035] Please see Figures 1-8The integrated washing and drying mechanism includes a mounting frame 11 fixedly connected to a mounting platform 1. A cleaning tank 12 is fixedly connected to the mounting frame 11. A first transmission pipe 13 is rotatably connected to the top of the cleaning tank 12. A transmission mechanism is rotatably connected to the outer surface of the first transmission pipe 13. Multiple cleaning pipes 14 of varying lengths are fixedly connected to the outer surface of the first transmission pipe 13. A baffle 15 is rotatably connected inside each cleaning pipe 14. A spring 16, fixedly connected to the cleaning pipe 14, is fixedly connected to one side of the baffle 15. A stop block 17 is fixedly connected inside each cleaning pipe 14. Cleaning brush plates 18 are fixedly connected to the top and bottom of each cleaning pipe 14. Electromagnetic plates 19 are fixedly connected to both sides of each cleaning pipe 14. The cleaning tank 12... A first discharge pipe 190 is fixedly connected to the bottom of the cleaning tank 12, and an electromagnetic valve is installed on the first discharge pipe 190. A drain pipe 191 is fixedly connected to the bottom of the cleaning tank 12, and an electromagnetic valve is installed on the drain pipe 191. A filter screen is fixedly connected to the water inlet end of the drain pipe 191. A supply mechanism is driven to the top of the first transmission pipe 13, and a first pushing mechanism connected to the cleaning tank 12 is driven to the outer surface of the first transmission pipe 13. A second pushing mechanism is installed inside the cleaning tank 12. A drying mechanism connected to the mounting platform 1 is installed below the cleaning tank 12. After the quartz sand to be cleaned is fed into the cleaning tank 12 by the elevator 4, cleaning water is then supplied to the first transmission pipe 13 through the supply mechanism. Cleaning water is introduced into the cleaning pipe 14. Under the action of water pressure, the baffle 15 inside the cleaning pipe 14 is pushed open, and the spring 16 is stretched. At the same time, when cleaning stops, the restoring force of the spring 16 drives the baffle 15 to return to its initial position, closing the cleaning pipe 14 and preventing the quartz sand from clogging it. Then, water is sprayed out through the various cleaning pipes 14 of different lengths. Simultaneously, the transmission mechanism drives the first transmission pipe 13 to rotate, which in turn drives the cleaning pipes 14 to rotate, rinsing the quartz sand in the cleaning box 12 from the inside out. At the same time, the cooperation of the first and second pushing mechanisms ensures that the quartz sand in the cleaning box 12 is fully transported, thereby achieving thorough rinsing of the quartz sand in the cleaning box 12. The cleaning brush plates 18 at the top and bottom of the cleaning pipe 14 brush away impurities and dirt from the surface of the quartz sand, thus achieving a thorough cleaning of the quartz sand in the cleaning tank. The wastewater after cleaning is discharged through the drain pipe 191. Simultaneously, during the cleaning process, the electromagnet plate 19 on the outer surface of the cleaning pipe 14 is energized to attract iron filings from the quartz sand. The first and second pushing mechanisms work together to comprehensively transport the quartz sand, ensuring the electromagnet plate 19 fully attracts the iron filings, greatly improving the removal of iron filings from the quartz sand. After the quartz sand is cleaned, the water supply is stopped, and the cleaned quartz sand is then fed into the drying mechanism through the first discharge pipe 190.Subsequently, hot air is supplied to the first transmission pipe 13 through the supply mechanism. The hot air blows hot air into the cleaning box 12 by opening the baffle 15 on the cleaning pipe 14, simultaneously driving the first transmission pipe 13 to rotate. At the same time, the first and second pushing mechanisms operate. The hot air dries the water on the quartz sand inside the cleaning box 12, causing the quartz sand to quickly detach from the cleaning box 12 and the surfaces of the first transmission pipe 13, cleaning pipe 14, and pushing mechanisms within the cleaning box 12. This allows for the rapid and thorough discharge of the cleaned quartz sand, preventing some of the cleaned quartz sand from being unable to exit the cleaning box 12 due to water adhesion. After discharge, the supply mechanism is then increased... The power of the hot air supply is increased. At this time, the receiving mechanism on the drying mechanism enters below the first discharge pipe 190. Subsequently, the electromagnet plate 19 is de-energized, and the electromagnet plate 19 no longer generates magnetism. At the same time, due to the increased power supply of hot air inside the cleaning box 12, the temperature inside the cleaning box 12 rises, causing the electromagnet plate 19 to quickly lose its magnetism under high temperature. At this time, the adsorbed iron filings fall from the electromagnet plate 19 into the receiving mechanism for collection, thereby achieving rapid and effective removal of the adsorbed iron filings. This effectively prevents some iron filings from remaining adsorbed on the electromagnet plate 19 and not being discharged after the electromagnet plate 19 is de-energized, thus achieving complete removal of iron filings from the quartz sand.
[0036] The first pushing mechanism includes a transmission box 21 fixedly connected to the cleaning tank 12. The transmission box 21 is rotatably connected to the first transmission pipe 13. A first transmission gear 22 is fixedly sleeved on the outer surface of the first transmission pipe 13. A second transmission gear 23 is meshed on the outer surface of the first transmission gear 22.

The transmission mechanism drives the first transmission tube 13 to rotate forward and backward, thereby driving the first spiral rod 27 to rotate forward and backward. The first spiral rod 27 drives the quartz sand in the cleaning tank 12 to move left and right. At the same time, the first spiral rods 27 in the upper and lower layers of the cleaning tank 12 are arranged crosswise, thereby realizing the movement of the quartz sand in the cleaning tank 12 from the inside out and from the outside in. At the same time, the first drive mechanism drives the second spiral rod 28 to rotate forward and backward, and the second spiral rod 28 drives the quartz sand in the cleaning tank 12 to move up and down, thereby realizing the comprehensive movement of the quartz sand in the cleaning tank 12.

The first drive motor 31 is controlled by a PLC programming program, which can control the forward and reverse rotation and the rotation angle of the first drive motor 31. The first drive motor 31 drives the first drive shaft 32 to rotate. The first drive shaft 32 drives the transmission gear ring 34 to rotate via the first drive gear 33. The transmission gear ring 34 drives the second drive gear 35 and the second helical rod 28 to rotate.
[0038] Example 3
[0039] Please see Figure 1 , Figure 3 , Figure 5 and Figure 9 The drying mechanism includes a drying box 41 fixedly connected to the mounting platform 1. A second transmission pipe 42 is rotatably connected to the bottom of the drying box 41. A drying cylinder 43 is fixedly connected to the top of the second transmission pipe 42.

A second drive mechanism connected to the drying box 41 is drivenly connected to the outer surface of the second transmission pipe 42. A stirring rod 46 rotatably connected to the drying box 41 is fixedly connected to the bottom of the second spiral rod 28. An air supply mechanism connected to the mounting platform 1 is drivenly connected to the bottom of the second transmission pipe 42. An absorption hood 47 connected to the air supply mechanism is fixedly connected to the top of the drying box 41. A second discharge pipe 48 is fixedly connected to the bottom of the drying box 41. An electromagnetic valve is installed on the second discharge pipe 48. A receiving mechanism is provided at the top of the drying box 41. Hot air is supplied into the second transmission pipe 42 through the air supply mechanism, and then the hot air passes through… The second transmission pipe 42 enters the drying cylinder 43, and then the air is blown out through the air outlet 44 and the first filter plate 45 on the surface of the drying cylinder 43. Due to the inclined design of the drying cylinder 43, the drying cylinder 43 blows hot air upward at an angle. At the same time, the second spiral rod 28 drives the stirring rod 46 to rotate, and the second drive mechanism drives the second transmission pipe 42 and the drying cylinder 43 to rotate, thereby enabling the quartz sand to be quickly dried by hot air blowing. After drying, due to the upward blowing of hot air, the light impurities in the quartz sand are pushed towards the surface. The air is blown upwards, and in conjunction with the stirring of the stirring rod 46 and the rotation of the drying cylinder 43, the light impurities in the quartz sand are completely blown upwards. Then, through the cooperation of the air supply mechanism and the absorption hood 47, the light impurities blown upwards are sucked out, thereby achieving rapid drying of the washed quartz sand and removal of light impurities. Then, by opening the second discharge pipe 48, the discharge plate 49 is driven to rotate by the drying cylinder 43. The discharge plate 49 scrapes the dried quartz sand into the second discharge pipe 48 and discharges it from the second discharge pipe 48.
[0040] The air supply mechanism includes a first connecting pipe 51 rotatably connected to the second transmission pipe 42, the first connecting pipe 51 being fixedly connected to the drying chamber 41, a first hot air blower 52 being fixedly connected to the bottom end of the first connecting pipe 51 via a pipe, a drying chamber 53 being fixedly connected to the mounting platform 1 via a pipe at the input end of the first hot air blower 52, a silica gel desiccant mesh frame 54 being slidably connected inside the drying chamber 53, a suction fan 55 being fixedly connected to one side of the drying chamber 53 via a pipe, and a filter box 56 being fixedly connected to the drying chamber 53 via a pipe at the output end of the suction fan 55.

A third drive gear 591 is fixedly sleeved on the outer surface of the second drive shaft 590. A fourth drive gear 592, which is fixedly sleeved on the outer surface of the third drive gear 591, is meshed with the outer surface of the third drive gear 591. The second drive motor 59 drives the second drive shaft 590 to rotate. The second drive shaft 590 drives the second transmission pipe 42 to rotate via the third drive gear 591 and the fourth drive gear 592. Hot air is supplied through the first hot air blower 52 and the first connecting pipe 51 of the pipe box. The hot air is discharged through the drying cylinder 43. At the same time, through the cooperation of the suction fan 55 and the pipe, the hot air that has been dried in the drying box 41 is drawn through the absorption hood 47 and the pipe into the filter box 56. Then, light impurities are filtered through the third filter plate 58 and the second filter plate 57, while dust generated during the drying process is also filtered. The process involves filtration to remove light impurities from the quartz sand and to filter out dust generated during the drying process. The filtered hot air then enters the silica gel desiccant mesh frame 54 inside the drying chamber 53, where the desiccant absorbs moisture and dries the sand. The dried hot air then enters the first hot air blower 52 for further heating and reuse, thus achieving a closed-loop drying process. This improves heat recovery and increases the drying efficiency of the quartz sand while also saving energy. After use, the silica gel desiccant frame can be removed, and the desiccant can be air-dried for reuse.

When the first discharge pipe 190 discharges quartz sand, the electric telescopic rod 65... 5. Move the connecting plate 63, sealing plate 62 and receiving box 64 to the right so that the sealing plate 62 no longer blocks the receiving funnel 61. When the first discharge pipe 190 stops discharging and the quartz sand is dried, the connecting plate 63, sealing plate 62 and receiving box 64 are moved to the left by the electric telescopic rod 65. The sealing plate 62 seals the receiving funnel 61.

An electromagnetic valve is installed on the air inlet pipe. When water needs to be supplied to the first transmission pipe 13, the electromagnetic valve on the water inlet pipe is opened and the electromagnetic valve on the air inlet pipe is closed. Then, the water pump 73 supplies external cleaning water into the first transmission pipe 13 through the supply pipe 72, pipe, and second connecting pipe 71. When hot air is supplied, the electromagnetic valve on the water inlet pipe is closed and the electromagnetic valve on the air inlet pipe is opened.

A second gear 84 is meshed with the outer surface of the first gear 83 and fixedly sleeved on the first transmission tube 13. The transmission motor 81 is controlled by a PLC programming program, which can control the forward and reverse rotation and the rotation angle of the transmission motor 81. The transmission motor 81 drives the first rotating shaft 82 to rotate, and the first rotating shaft 82 drives the first transmission tube 13 to rotate via the first gear 83 and the second gear 84.
[0044] The working principle of this invention is as follows: After the quartz sand to be cleaned is fed into the cleaning tank 12 by the elevator 4, cleaning water is then supplied to the first transmission pipe 13 through the supply mechanism. The cleaning water then flows into the cleaning pipe 14, and under the action of water pressure, it pushes open the baffle 15 inside the cleaning pipe 14, causing the spring 16 to be stretched. Simultaneously, when cleaning stops, the restoring force of the spring 16 causes the baffle 15 to return to its initial position, closing the cleaning pipe 14 and preventing the quartz sand from clogging it. Water then sprays out through the various cleaning pipes 14 of different lengths. At the same time, the transmission mechanism drives the first transmission pipe 13 to rotate, which in turn drives the cleaning pipe 14 to rotate, thus rinsing the quartz sand in the cleaning tank 12 from the inside out. The first and second pushing mechanisms work together to comprehensively transport the quartz sand in the cleaning tank 12, thereby achieving thorough rinsing of the quartz sand. Simultaneously, the cleaning brush plates 18 at the top and bottom of the cleaning pipe 14 scrub away impurities and dirt from the surface of the quartz sand, ensuring a comprehensive and thorough cleaning of the quartz sand in the cleaning tank. The wastewater after cleaning is discharged through the drain pipe 191. During the cleaning process, the electromagnet plate 19 on the outer surface of the cleaning pipe 14 is energized to attract iron filings from the quartz sand. The combined action of the first and second pushing mechanisms to comprehensively transport the quartz sand allows the electromagnet plate 19 to fully and thoroughly attract the iron filings, greatly improving the cleaning efficiency of the quartz sand. After the iron filings are removed and the quartz sand is washed, the water supply is stopped. The washed quartz sand is then fed into the drying mechanism through the first discharge pipe 190. Hot air is then supplied to the first transmission pipe 13 via the supply mechanism. The hot air blows hot air into the cleaning chamber 12 by opening the baffle 15 on the cleaning pipe 14, simultaneously rotating the first transmission pipe 13 and activating the first and second pushing mechanisms. The hot air dries the water off the quartz sand inside the cleaning chamber 12, causing it to quickly detach from the cleaning chamber 12 and the surfaces of the first transmission pipe 13, cleaning pipe 14, and pushing mechanisms. This allows for the rapid and thorough discharge of the washed quartz sand, preventing some of the washed sand from being discharged. The quartz sand cannot be discharged from the washing tank 12 due to the adhesion of water. After discharge, the power of the hot air supplied by the supply mechanism is increased. At this time, the receiving mechanism on the drying mechanism enters below the first discharge pipe 190. Then, the electromagnet plate 19 is de-energized, and it no longer generates magnetism. At the same time, the increased power of the hot air supply inside the washing tank 12 raises the temperature inside the washing tank 12, causing the electromagnet plate 19 to quickly lose its magnetism in the high-temperature environment. At this time, the adsorbed iron filings fall from the electromagnet plate 19 into the receiving mechanism for collection, thereby achieving rapid and effective removal of the adsorbed iron filings. This effectively prevents iron filings from remaining adsorbed on the electromagnet plate 19 due to its magnetism after de-energization and being unable to be discharged.This method achieves complete removal of iron filings from silica sand.
[0045] Hot air is supplied into the second transmission pipe 42 through the air supply mechanism, and then enters the drying cylinder 43 through the second transmission pipe 42. The hot air is then blown out through the air outlet 44 and the first filter plate 45 on the surface of the drying cylinder 43. Due to the inclined design of the drying cylinder 43, the hot air is blown upwards at an angle. Simultaneously, the second spiral rod 28 drives the stirring rod 46 to rotate, and the second drive mechanism drives the rotation of the second transmission pipe 42 and the drying cylinder 43, thereby rapidly drying the quartz sand with hot air. After drying, the upward blowing of the hot air... The process involves blowing light impurities in the quartz sand upwards, which, combined with the stirring of the stirring rod 46 and the rotation of the drying cylinder 43, ensures that all light impurities in the quartz sand are blown upwards. Subsequently, the air supply mechanism and the absorption hood 47 work together to suck out the upward-blown light impurities, thereby achieving rapid drying and removal of light impurities from the washed quartz sand. Then, by opening the second discharge pipe 48 and simultaneously rotating the discharge plate 49 driven by the drying cylinder 43, the discharge plate 49 scrapes the dried quartz sand into the second discharge pipe 48 and discharges it from the second discharge pipe 48.
