Description

Technical Field

[0001] The invention relates to the technical field of glass manufacturing and processing, in particular to a chlorination purification device for quartz sand. Background Art

[0002] The chlorination and purification technology of quartz sand refers to the process of chlorination roasting, which is a process in which certain components in mineral raw materials are converted into gaseous or condensed chlorides under the action of a chlorinating agent under certain conditions, thereby separating or enriching the components. Chlorination roasting is also called chlorination degassing. Chlorination roasting of quartz sand is one of the technologies in the purification process of high-purity quartz sand. It is mainly aimed at the treatment of lattice impurities in quartz sand to obtain high-purity quartz sand with a SiO2 weight content greater than 99.9%.

[0003] In the prior art, the chlorination purification device applied to quartz sand can perform purification treatment by injecting the quartz sand raw material into the interior of the heating pipe and then introducing the chlorinating agent simultaneously. In order to achieve continuous processing, the quartz sand is generally driven to move in the form of vibration or controlling the rotation of the pipe. This type of driving form has high instability, and the residence time of quartz sand at different positions in the heating area has a large deviation, which will lead to differences in the final purification effect of quartz sand at different positions. On the other hand, when the chlorinating agent is introduced, the chlorinating agent is injected from one end of the pipe, so the concentration will decrease rapidly from the front end to the end, and it will be difficult to penetrate and mix from the surface to the bottom layer, so the concentration of the chlorinating agent contacted by the quartz sand already at the rear end will decrease, and the chlorination purification effect will be greatly reduced.

DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0027] See also Figures 1 to 6 The present invention provides the following technical solutions: a chlorination purification device for quartz sand, comprising a purification device body, the purification device body comprising an electric heating box 1, a purification pipeline 5 and a driving mechanism 8, a chlorinating agent delivery pipeline 4 is plugged into the top of the electric heating box 1, the purification pipeline 5 passes through the inner bottom end of the electric heating box 1, and the purification pipeline 5 is fixed to the outer shell of the electric heating box 1 as a whole, a ventilation bin 13 is installed on the surface of the purification pipeline 5, the end of the chlorinating agent delivery pipeline 4 is connected to the interior of the ventilation bin 13, and one end of the bottom of the electric heating box 1 is welded with The vertical plate 7, the bottom of the end of the purification pipeline 5 is integrally formed with a discharge channel 16, the side of the discharge channel 16 is fixed with a vacuum assembly 10, and the bottom of the discharge channel 16 is sleeved with a discharge box 9, the purification pipeline 5 and the electric heating box 1 are tilted as a whole, and the bottom of the inner wall of the electric heating box 1 is embedded with an electric heating wire, and the end of the vacuum assembly 10 is welded with an exhaust pipe 12. The quartz sand chlorination purification device is used to put the quartz sand raw material into the interior of the purification pipeline 5, and then after the chlorination agent is introduced and high-temperature heating treatment is provided, the purpose of chlorination purification is achieved.

[0028] When the present invention is used, the quartz sand raw material is directly put into the interior from the top of the feed channel 15 at one end of the purification pipeline 5. After the internal driving mechanism 8 is started, each guide mechanism 19 on the driving shaft 18 is driven to rotate by means of the driving mechanism 8, and each guide mechanism 19 is controlled to operate periodically, and each time it rotates half a circle, the quartz sand put in from a high place can be blocked by the arc baffle 20 in the guide mechanism 19 in turn, and is fully mixed with the dissolved chlorinating agent during the blocking process, and is heated and purified until it moves downward step by step with the repeated start of the guide mechanism 19, and finally slides into the discharge channel 16 at the bottom, and is discharged downward in the discharge channel 16. At the same time, the chloride generated in the purification process is also extracted with the help of the exhaust component 10 on one side of the discharge channel 16.

[0029] In this embodiment, a front bracket 3 is welded to one end of the electric heating box 1, and a rear bracket 2 is welded to the other end of the electric heating box 1. The driving mechanism 8 includes a motor 17 and a driving shaft 18. The driving shaft 18 is plugged into the output end of the motor 17, and a flow guide mechanism 19 is integrally formed on the surface of the driving shaft 18. The outer shell of the motor 17 is screwed to the outside of the rear bracket 2, and an end plate 6 is welded to the bottom of the end of the rear bracket 2. One end of the purification pipeline 5 is against the surface of the end plate 6. The driving shaft 18 passes through the interior of the purification pipeline 5 as a whole, and the central axis of the driving shaft 18 and the purification pipeline 5 coincide. The end of the driving shaft 18 is embedded in the interior of the end plate 6 through a bearing. A feed channel 15 is installed at the top of one end of the purification pipeline 5. A feeding port 14 is opened at the top of the feed channel 15, and the interior of the feed channel 15 is connected to the interior of the purification pipeline 5.

[0030] Specifically, by supporting the brackets at both ends simultaneously through the middle electric heating box 1, the purification pipeline 5 below can be tilted. At this time, the quartz sand dropped from the top can slide down along the purification pipeline 5 with the help of its own gravity, and be blocked by each guide mechanism 19 in turn until it passes through the interior of the purification pipeline 5. The purpose of chlorination purification is achieved in this process.

[0031] In this embodiment, the flow guiding mechanism 19 includes an arc-shaped baffle 20 and a scraper 21. The arc-shaped baffle 20 is integrally formed on the surface of the driving shaft 18. A flow guiding capillary 23 is integrally formed at the bottom of the scraper 21. A strip-shaped hole 22 is provided on the outer side of the scraper 21. The flow guiding capillary 23 passes through the middle of the driving shaft 18. A lead-out hole 24 is provided at the end of the flow guiding capillary 23. The arc-shaped baffle 20 is a semicircular structure as a whole. The side edges of the arc-shaped baffle 20 and the side edges of the scraper 21 are both in contact with the inner wall of the purification pipe 5. The end of the flow guiding capillary 23 is pressed against the inner wall of the purification pipe 5. The purification pipe 5 is tilted and arranged, and cooperates with the driving mechanism 8 and multiple guide mechanisms 19 on the inner side, so that the put quartz sand can be moved down step by step in batches, and the amount of quartz sand temporarily stored at each level is fixed, so that the quartz sand at any position will stay at each level for a fixed time, and thus the final purification effect of the quartz sand at any position remains consistent.

[0032] Specifically, after starting the motor 17, the motor 17 drives the driving shaft 18 to rotate, and the driving shaft 18 drives each flow guide mechanism 19 on the surface to rotate. Since the arc baffles 20 between adjacent flow guide mechanisms 19 are in opposite directions, the quartz sand released from the top is first blocked by the highest arc baffle 20 pointing downward. After the motor 17 is started again, the top arc baffle 20 rotates from bottom to top to release the blockage of the quartz sand. At this time, this part of the quartz sand passes through the arc baffle 20, rolls toward the bottom, and is then blocked by the second arc baffle 20. The above process is repeated, and each arc baffle 20 is released in turn, and it always stays for a fixed time. As the top feed channel 15 continues to release quartz sand, it can be ensured that the time for quartz sand at any position to pass through the inside of the purification pipeline 5 is always the same.

[0033] In this embodiment, a plurality of shunt cavities 31 are provided inside the ventilation bin 13, and adjacent shunt cavities 31 are separated by partitions 32, and a docking hole 33 is provided at the bottom of each shunt cavity 31, and a plurality of shunt pipes 34 are connected to the end of the chlorinating agent delivery pipeline 4. The end of each shunt pipe 34 is inserted into the corresponding shunt cavity 31, and the scraper 21 is pressed on the surface of the docking hole 33 through the strip hole 22 on the surface, and the inside of the shunt cavity 31 is connected to the inside of the guide tube 23 after passing through the docking hole 33, the strip hole 22, and the scraper 21 in sequence. With the help of the ventilation bin 13, the external chlorinating agent is introduced into the interior of the purification pipeline 5, and in the process, each guide mechanism 19 is cooperated, so that an equal amount of chlorinating agent can be directly and evenly introduced from each position of the heating area to the bottom position of the quartz sand, so that the introduced chlorine gas is more evenly distributed, and the final purification efficiency of the quartz sand at the front and rear ends remains unchanged.

[0034] Specifically, when the driving shaft 18 drives the flow guiding mechanism 19 to rotate, it also drives the scraper 21 and the flow guiding capillary 23 to rotate at the same time. The scraper 21 rotates along the inner wall of the purification pipeline 5 to scrape the quartz sand accumulated below, so as to prevent part of the quartz sand from adhering to the inner wall of the purification pipeline 5. At the same time, it will contact with part of the docking holes 33 through the strip holes 22 on the cover plate 29. Since the top chlorinating agent delivery pipeline 4 evenly introduces the chlorinating agent into each diversion cavity 31, the chlorinating agent in each diversion cavity 31 will also be introduced into the interior of the purification pipeline 5 through the docking holes 33 at the bottom, and part of the chlorinating agent will pass through the strip holes 22 and be directly transported from the bottom outlet hole 24 to the bottom position of the quartz sand along the scraper 21 and multiple flow guiding capillary 23, thereby ensuring that the bottom part of the quartz sand can also be directly mixed and contacted with the introduced chlorinating agent.

[0035] In this embodiment, the air extraction component 10 includes a fan 11 and an air extraction pipe 25, one end of the air extraction pipe 25 is connected to the inside of the discharge channel 16, the fan 11 is screwed to the other end of the air extraction pipe 25, and the exhaust pipe 12 is connected to the output end of the fan 11. A sliding sleeve 26 is inserted into the interior of the air extraction pipe 25, one end of the sliding sleeve 26 is integrally formed with a top plate 27, a screen 28 is laid in the middle of the top plate 27, a fixing plate 30 is welded on the inner wall of the air extraction pipe 25, and a cover plate 29 is integrally formed at the bottom end of the fixing plate 30, a gap is set between the side of the cover plate 29 and the inner wall of the air extraction pipe 25, and the diameter of the cover plate 29 is larger than the diameter of the screen 28. A vacuum assembly 10 is installed on the side of the discharge channel 16. The vacuum assembly 10 cooperates with the periodic movement of the driving mechanism 8 and can be started within the interval time period of the step-by-step conveying of the quartz sand, thereby avoiding the phenomenon that the quartz sand is continuously discharged and is sucked away during the vacuum process, thereby avoiding blockage and extending the service life and cleaning cycle of the filtering structure.

[0036] Specifically, since the quartz sand moves periodically, after the quartz sand is partially removed from the bottom guide mechanism 19, it will directly fall downward from the discharge channel 16. The falling is also realized periodically. Therefore, the driving structure is started and within a few seconds after the start, the fan 11 stops running until the batch of quartz sand falls into the discharge box 9 at the bottom. At this time, the fan 11 is started to draw the gas inside the discharge channel 16 into the exhaust pipe 25, and finally discharged from the exhaust pipe 12. At this time, the sliding sleeve 26 is Under the action of airflow, it moves toward the position of the fan 11, and the screen 28 is not blocked by the cover plate 29, so the airflow can flow. After the air extraction is completed, the fan 11 is started by reverse control to blow the sliding sleeve 26, so that the top plate 27 and the screen 28 are against the inner side of the cover plate 29. At this time, the air extraction channel is closed and the screen 28 is also blocked. After the motor 17 is started again, the quartz sand falling from the discharge channel 16 will be blocked by the cover plate 29 and will not directly contact the screen 28, thereby preventing the screen 28 from being blocked by the quartz sand.
