Description

Technical Field

[0001] The invention relates to the technical field of quartz sand purification, in particular to an L-shaped heating chlorination device. Background Art

[0002] After crushing, quartz sand needs to be purified before use in photovoltaic and optoelectronics applications. Currently, high-temperature chlorination is commonly used for purification. This process can further reduce the levels of impurities such as Fe, Na, K, and Ca in the sand, thereby increasing its purity. To ensure sufficient contact between the sand and the hydrogen chloride gas, a sand-scooping mechanism is installed within the reaction chamber to tumble the sand, allowing for a thorough reaction. However, current quartz sand heating and chlorination systems typically use a rotating drum to tumble the sand. Due to its own gravity, the sand remains deposited at the bottom of the drum for most of the time, where it accumulates and hinders sufficient contact with the chlorine gas.

[0028] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0029] like Figure 1As shown, an L-shaped heated chlorination unit comprises a first-stage high-temperature chlorination module and a second-stage high-temperature chlorination module, connected by a feed pipe 5. The second-stage high-temperature chlorination module is arranged vertically, while the first-stage module is slightly tilted horizontally, forming an "L" shape. The first-stage high-temperature chlorination module comprises a first high-temperature chlorination cylinder 1, and the second-stage high-temperature chlorination module comprises a second high-temperature chlorination cylinder 16. A drum 4 is rotatably connected to the first drum 1 via a second bearing. A feed barrel is located within the second drum 16. Both the first and second drums 1, 16 are axially spaced apart with electric auxiliary heating units and microwave heating units. These units heat the drum 4 and feed barrel, providing the necessary temperature for the impurity chlorination reaction. Quartz sand first passes through the first-stage high-temperature chlorination module before entering the second-stage high-temperature chlorination module. Both the first and second drums 1, 16 are fixedly mounted on a frame 2.

[0030] like Figures 2 to 9 As shown, the outside of the drum 4 is connected to a drive unit, which includes a first motor 9. A gear 10 is mounted on the output shaft of the first motor 9. A circle of transmission teeth 11 is provided on the outside of the drum 4, and the gear 10 meshes with the transmission teeth 11. When the first motor 9 rotates, the gear 10 rotates, and the rotation of the gear 10 drives the drum 4 to rotate through the transmission teeth 11.

[0031] A feed connection pipe 7 is inserted into the front end of the drum 4, which is connected to the feed hopper 3. Quartz sand is added from the feed hopper 3 and enters the drum 4 through the connection pipe 7. Both the feed connection pipe 7 and the drum 4 are arranged at an angle. An air inlet pipe 12 is connected to the upper side of the feed connection pipe 7, which continuously introduces chlorine gas into the drum 4. The rear end of the drum 4 is inserted into the discharge connection barrel 8, and an exhaust pipe 13 is connected to the top of the discharge connection barrel 8. Exhaust pipe 13 is used to exhaust the reacted gas, thereby ensuring a stable air pressure in the drum 4. Both the air inlet pipe 12 and the exhaust pipe 13 are equipped with air valves. By adjusting these two valves, the chlorine content in the drum 4 can be controlled to ensure the reaction and purification effect.

[0032] like Figure 9 As shown, the feed connecting pipe 7 is sealed and rotatably connected to the drum 4, and the discharge connecting pipe 8 is rotatably and sealably connected to the drum 4. An annular groove 19 is provided on the outside of the feed connecting pipe 7. A rubber sealing ring 20 is fixed to the inside of one end of the drum 4, embedded in the annular groove 19, and rotatably connected to the annular groove 19. An annular groove is provided on the other end of the drum 4, and a rubber sealing ring is fixed to the inside of one end of the discharge connecting pipe 8, embedded in the annular groove, and rotatably connected to the annular groove, thereby forming a good sealing effect and reducing the leakage of chlorine gas.

[0033] A rotating shaft 15 is rotatably connected to the interior of the drum 4. Specifically, a rotating shaft bracket 17 is fixed to the interior of the drum 4 and rotatably connected to the rotating shaft 15 via a first bearing 18. Multiple sand-splitting blades 6 are mounted on the rotating shaft 15. A second motor 14 is mounted outside the discharge connection barrel 8. The output end of the second motor 14 extends into the discharge connection barrel 8 and connects to the end of the rotating shaft 15. The output end of the second motor 14 is rotatably and sealedly connected to the discharge connection barrel 8. Both the first motor 9 and the second motor 14 are fixed to the frame 2. The sand-splitting blades 6 are circumferentially distributed outside the rotating shaft 15, and the blades 6 are evenly spaced axially along the rotating shaft 15. Rotation of the second motor 14 drives the rotating shaft 15. During operation, the second motor 14 rotates in the opposite direction to that of the first motor 9, meaning that the rotating shaft 15 rotates in the opposite direction to that of the drum 4. Rotation of the rotating shaft 15 causes the quartz sand to tumble through the sand-splitting blades 6.

[0034] The sand-scooping blades 6 comprise two parallel blade units 63, one side of which is fixedly connected to the rotating shaft 15 via two supports 61. A shovel plate 66 is connected to each blade unit 63 on the side facing away from the rotating shaft 15. The shovel plates 66 and blade units 63 are arranged at the same angle, forming an expanded opening. A material-dropping hole 69 is provided between the blade units 63. As the rotating shaft 15 rotates, the shovel plate 66 on one side scoops up the quartz sand. As the rotating shaft 15 continues to rotate in that direction, the quartz sand falls onto the blade unit 63 on that side. To prevent the quartz sand from sliding off the ends of the shovel plates 66 during this process, anti-drop baffles 67 are provided at the ends of each blade unit 66. These baffles 67 are located on the side facing away from each other to prevent the sand from sliding off the ends of the blade units 66.

[0035] A first through-slot 62 is provided on one side of the blade unit 63 near the rotating shaft 15. The first through-slot 62 communicates with the blanking hole 69. As the blade unit 63 rotates upward from a horizontal position, the quartz sand slides down the blade unit 63 under its own gravity, passes through the first through-slot 62, and falls onto the rotating shaft 15. From there, it falls along the rotating shaft 15 to the bottom of the drum 4, allowing the quartz sand to fully come into contact with the chlorine gas and allow the impurities to react fully.

[0036] The sides of the two blade units 63 facing away from each other are each equipped with a plurality of equally spaced horizontal bars 64 and vertical bars 65. The horizontal bars 64 and vertical bars 65 are perpendicular to each other and form a plurality of rectangular frames. When the blade units 63 rotate upward from a horizontal position, the quartz sand slides down along the blade units 63 under its own gravity. The rectangular frames formed by the horizontal and vertical bars 64 and 65 retain some of the quartz sand within the rectangular frames, preventing it from falling out. This helps the thin layer of quartz sand fully contact the chlorine gas. The quartz sand in the rectangular frames will not be poured out until the blade units 63 rotate downward from the top.

[0037] Furthermore, each shovel blade 66 is provided with a hook plate 68 at its end, located on the side where the two shovel blades 66 are close to each other. When the blade units 63 rotate in one direction, the shovel plate 66 on one blade unit 63 scoops up some quartz sand, while the hook plate 68 on the adjacent blade unit 63 also scoops up some quartz sand. During the upward rotation, the quartz sand on the inner side of the hook plate 68 slides along the drop groove 69 to the first groove 62, falls onto the rotating shaft 15, and finally falls to the bottom of the drum 4. In this process, the quartz sand is picked up and scattered, thereby facilitating sufficient contact between the quartz sand and the chlorine gas. Similarly, when the rotating shaft 15 rotates in the opposite direction, the blade units 63 on both sides have the same structure, so the effect is the same.

[0038] A plurality of annular protrusions 1501 are equidistantly arranged on the rotating shaft 15 to prevent the quartz sand from sliding down along the rotating shaft 15 when the quartz sand falls onto the rotating shaft 15 , thereby increasing the contact time between the quartz sand and the chlorine gas and improving the purification effect of the quartz sand.
