Description

Technical Field

[0001] This invention relates to the field of quartz sand chlorination technology, specifically to a high-efficiency quartz sand chlorination device. Background Technology

[0002] Currently, high-purity quartz sand refers to quartz sand with a SiO2 purity greater than 99.99%. It is a raw material for producing high-grade quartz products. Due to its excellent physicochemical properties such as high temperature resistance, corrosion resistance, low thermal expansion, high insulation, and light transmittance, it is widely used in high-tech industries such as fiber optic communication, solar photovoltaics, aerospace, electronics, and semiconductors, holding a very important strategic position. Our existing high-purity quartz sand purification methods follow these principles: Source: High purity, with a silica content of over 99%; Coarse processing: Crushing, washing, gravity separation, magnetic separation, flotation, calcination + water quenching; Deep processing: Acid leaching, roasting, high-temperature chlorination, etc. Existing purification technologies generally employ high-temperature chlorination purification of quartz sand. This technology utilizes the phase transition of quartz crystals under different high-temperature conditions, which leads to structural reorganization, resulting in volume expansion and tearing, and the generation of numerous microcracks inside. Simultaneously, hydrogen chloride or chlorine gas is introduced, which reacts with impurities in the quartz sand, such as iron, sodium, and potassium, at high temperatures to form gaseous metal chlorides with low boiling points. These chlorides escape from the high-purity quartz sand system, thereby reducing the impurity content in the quartz sand.

[0003] A search revealed a patent publication number CN214233985U that discloses a horizontal high-temperature gasification and purification device for quartz sand. The device includes a support plate, with two fixed columns at one end of the upper surface of the support plate, a support column between the two fixed columns, and a sleeve column at the other end of the upper surface of the support plate. A toothed column is slidably inserted into the inner cavity of the sleeve column. The gasification device body is located between the toothed column and the support column. A rotating rod is located in the middle of the rotating gears, with a first motor at one end of one rotating rod and a first positioning column at one end of the other rotating rod. Two connecting gears are located between the two rotating gears, and a second positioning column is located at one end of each of the two connecting columns.

[0004] In the aforementioned patent literature, the meshing connection of connecting gears facilitates the stable up-and-down movement of the sleeve column through the rotation of two rotating gears. This allows for material tilting within the internal cavity of the gasification device, resulting in smoother material discharge. However, the drawback of the device and method is that the method by which chlorine gas or chlorine compounds enter the quartz sand is not clearly defined. This means that the quartz sand only comes into contact with and reacts with the chlorine gas at the outlet, leading to low chlorination efficiency and quality. Therefore, a high-efficiency quartz sand chlorination device is urgently needed to solve this problem. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, the worker can start the stirring motor to rotate the transmission worm gear, which in turn drives the transmission worm wheel to rotate. The transmission worm wheel is fixedly connected to the rotating column, which in turn drives the tower base to rotate. Since auger blades are fixedly installed on the side wall of the tower base, and the tower base is conical, when the tower base rotates, the quartz sand particles are conveyed upwards in a U-shaped circulation, circulating the quartz sand outside and inside the chlorination tank. The rotation of the tower base also drives the top sleeve to rotate, and with the cooperation of the mounting sleeve… The base plate, fixedly installed on the side wall of the sliding bent rod, drives the stirring rod to rotate, thereby mixing the quartz sand in the chlorination tank. When the stirring motor operates at high power, the top sleeve drives the mounting sleeve to rotate at high speed. Under the centrifugal force of the centrifugal plate and the sliding bent rod, the sliding bent rod can move to the outside of the inner cavity of the mounting sleeve. At this time, the sliding bent rod can change the stirring radius of the stirring rod on the side wall of the base plate. Thus, through the above-mentioned methods, this device can achieve mixing of quartz sand with different stirring ranges, improving the mixing quality of quartz sand in the entire device.

[0017] 2. In this invention, when the top sleeve rotates, the extension rod fixed on its side wall can drive the cam block to rotate. The cam block can continuously squeeze the abutment rod to make the blocking block move left and right within the inner diameter of the control box. When the blocking block slides into the left side of the inner cavity of the control box, the blocking block will lose its ability to block the vent pipe on the control box. At this time, the chlorine gas in the airbag ring can enter the inner cavity of the connecting ring through the vent pipe. Through the through hole opened on the side wall of the extension rod, the chlorine gas in the inner cavity of the connecting ring can enter the inner cavity of the stirring rod through the extension rod, top sleeve, mounting sleeve, sliding bent rod and bottom plate. Finally, it is discharged from the air hole on the stirring rod into the chlorination tank. With the stirring mechanism, the quartz sand and chlorine gas can be fully mixed, thereby greatly improving the efficiency of the entire device in chlorinating quartz sand.

It also includes: A stirring mechanism 6 is located in the middle of the bottom surface of the inner cavity of the chlorination tank 1. The stirring mechanism 6 is used to mix the quartz sand in the chlorination tank 1. The chlorination mechanism 7 is located in the middle of the upper end face of the chlorination tank 1. The chlorination mechanism 7 is used to add chlorine gas into the chlorination tank 1. Purification mechanism 8 is located at the end of pressure relief pipe 5 and is used to absorb unreacted chlorine gas and volatile chlorides.

[0022] Furthermore, the stirring mechanism 6 includes a tower base 61 rotatably installed in the middle of the bottom surface of the inner cavity of the chlorination tank 1, and a rotating column 62 fixedly installed on the lower end face of the tower base 61. A transmission worm gear 63 is fixedly installed on the side wall of the rotating column 62. Vertical plates 64 are fixedly installed on the front and rear sides of the upper end face of the support base 2. A transmission worm gear 65 is rotatably installed between the vertical plates 64 on the front and rear sides. The transmission worm 65 is meshed with the transmission worm wheel 63, the rotating column 62 is connected through the chlorination tank 1, and the rear side of the upper end face of the support base 2 is fixedly installed with the stirring motor 66 through the frame. The output shaft end of the stirring motor 66 is fixedly connected to the transmission worm 65. The tower base 61 is conical in shape, and auger blades 611 are wound and installed on the side wall of the tower base 61. A top sleeve 67 is fixedly installed on the upper end face of the tower base 61. The top sleeve 67 is hollow, and an installation sleeve 68 is fixedly installed on the side wall of the top sleeve 67. The installation sleeve 68 is connected to the top sleeve 67. Centrifugal plate 681 is slidably installed in the inner cavity of mounting sleeve 68. A sliding bent rod 69 is fixedly installed on the end face of centrifugal plate 681. A return spring 691 is wound on the side wall of sliding bent rod 69. A base plate 692 is fixedly installed on the lower end face of sliding bent rod 69. A stirring rod 693 is fixedly installed on the upper end face of base plate 692. Top sleeve 67 is connected to stirring rod 693 through sliding bent rod 69. Several sets of air holes are opened on the side wall of stirring rod 693. One end of the reset spring 691 is fixedly installed on the side wall of the centrifugal plate 681, and the other end is fixedly installed on the inner side wall of the mounting sleeve 68. Several sets of stirring rods 693 are provided on the bottom plate 692. The bottom surface of the chlorination tank 1 is made of heat-absorbing material. A heat insulation cavity is provided on the inner side wall of the chlorination tank 1, and the outer side wall of the chlorination tank 1 is made of heat insulation material.

[0023] It should be noted that after the worker puts the quartz sand into the chlorination tank 1, the bottom surface of the inner cavity of the chlorination tank 1 can be heated by starting the electric heater 4. Under the heat conduction of the chlorination tank 1, the internal temperature of the chlorination tank 1 can be raised. When the internal temperature of the chlorination tank 1 reaches a suitable temperature, the worker can start the stirring motor 66 to make the transmission worm gear 65 rotate. The transmission worm gear 65 will drive the transmission worm wheel 63 to rotate. The transmission worm wheel 63 is fixedly connected to the rotating column 62. At this time, the rotating column 62 will drive the tower base 61 to rotate. Since the auger blades 611 are fixedly installed on the side wall of the tower base 61 and the tower base 61 is conical, when the tower base 61 rotates, the quartz sand particles can be conveyed upward to form a U-shaped circulation, circulating the quartz sand on the outside of the chlorination tank 1 and the quartz sand on the inside of the chlorination tank 1. When the tower base 61 rotates, it drives the top sleeve 67 to rotate as well. With the cooperation of the mounting sleeve 68, the bottom plate 692, which is fixedly installed on the side wall of the sliding bent rod 69, will drive the stirring rod 693 to rotate, so as to realize the function of mixing the quartz sand in the chlorination tank 1. When the stirring motor 66 is running at high power, the top sleeve 67 will drive the mounting sleeve 68 to rotate at high speed. Under the action of centrifugal force of the centrifugal plate 681 and the sliding bent rod 69, the sliding bent rod 69 can move to the outside of the inner cavity of the mounting sleeve 68. At this time, the sliding bent rod 69 can change the stirring radius of the stirring rod 693 on the side wall of the bottom plate 692. Thus, through the above, this device can realize the mixing of quartz sand with different stirring ranges, thereby improving the mixing quality of quartz sand in the whole device.

[0024] Furthermore, the chlorination mechanism 7 includes an extension rod 71 fixedly installed on the upper end face of the top sleeve 67, and a cam block 72 fixedly installed on the upper end face of the extension rod 71. A control box 74 is fixedly installed on the right side of the upper end face of the airbag ring 3 through the air inlet pipe 73. A blocking block 75 is slidably installed in the inner cavity of the control box 74. A stop rod 76 is fixedly installed on the right end face of the blocking block 75. A connecting spring 77 is wound on the side wall of the stop rod 76. The inner cavity of the airbag ring 3 is filled with chlorine gas. The side wall of the cam block 72 abuts against the push rod 76. The push rod 76 is connected through the control box 74. The cross-section of the blocking block 75 is trapezoidal. One end of the connecting spring 77 is fixedly installed on the side wall of the blocking block 75, and the other end is fixedly installed on the inner side wall of the control box 74. The extension rod 71 is hollow and connected to the top sleeve 67. A connecting ring 78 is rotatably installed on the side wall of the extension rod 71. A through hole 711 is opened in the inner cavity of the connecting ring 78 on the side wall of the extension rod 71. An air outlet pipe 79 connected to the control box 74 is fixedly installed on the side wall of the connecting ring 78. The outlet end of the air outlet pipe 79 is located in the middle of the bottom surface of the inner cavity of the control box 74.

[0025] It should be noted that when the top sleeve 67 rotates, the extension rod 71 fixed on its side wall can drive the cam block 72 to rotate. The cam block 72 can continuously squeeze the abutment rod 76 to make the blocking block 75 move left and right within the inner diameter of the control box 74. When the blocking block 75 slides into the left side of the inner cavity of the control box 74, the blocking block 75 will lose its ability to block the vent pipe 79 on the control box 74. At this time, the chlorine gas in the air bag ring 3 can enter the inner cavity of the connecting ring 78 through the vent pipe 79. Through the through hole 711 opened on the side wall of the extension rod 71, the chlorine gas in the inner cavity of the connecting ring 78 can enter the inner cavity of the stirring rod 693 through the extension rod 71, the top sleeve 67, the mounting sleeve 68, the sliding bent rod 69 and the bottom plate 692. Finally, it is discharged from the vent on the stirring rod 693 into the chlorination tank 1. With the help of the stirring mechanism 6, the quartz sand and chlorine gas can be fully mixed, thereby greatly improving the efficiency of the entire device in chlorinating the quartz sand.

[0026] Furthermore, the purification mechanism 8 includes a purification box 81 fixedly installed on the upper surface of the airbag ring 3, the bottom end of the pressure relief pipe 5 extends into the inner cavity of the purification box 81, a pressure relief valve is provided in the inner cavity of the pressure relief pipe 5, an activated carbon plate 82 is fixedly installed on the upper part of the inner cavity of the purification box 81, and the bottom surface of the inner cavity of the purification box 81 is filled with calcium hydroxide solution.

[0027] It should be noted that during the chlorination of quartz sand, the pressure relief valve installed in the inner cavity of the pressure relief pipe 5 is opened to periodically discharge the waste gas in the chlorination tank 1. At this time, the waste gas can enter the inner cavity of the purification box 81 through the pressure relief pipe 5 and mix with the calcium hydroxide solution in the purification box 81. The chlorine gas reacts with sodium hydroxide to produce sodium chloride, sodium hypochlorite and water. With the cooperation of the activated carbon plate 82, the toxic gases in the waste gas can be effectively absorbed, ensuring the health of the surrounding environment of the device.

[0028] Working principle: After the worker puts the quartz sand into the chlorination tank 1, the bottom surface of the inner cavity of the chlorination tank 1 can be heated by activating the electric heater 4. Through heat conduction, the internal temperature of the chlorination tank 1 can be raised. Once the internal temperature of the chlorination tank 1 reaches a suitable temperature (generally 1200℃-1500℃), the worker can proceed. The inner wall of the chlorination tank 1 is equipped with a heat-insulating cavity, and the outer wall is made of heat-insulating material, effectively preventing burns to the worker's skin and improving the safety of the entire device. The stirring motor 66 is started, causing the transmission worm gear 65 to rotate. The transmission worm gear 65 will drive the transmission worm wheel 63 to rotate. The transmission worm wheel 63 is fixedly connected to the rotating column 62. At this time, the rotating column 62 will drive the tower base 61 to rotate. Since the auger blades 611 are fixedly installed on the side wall of the tower base 61 and the tower base 61 is conical, when the tower base 61 rotates, the quartz sand particles can be conveyed upward to form a U-shaped circulation, circulating the quartz sand on the outside of the chlorination tank 1 and the quartz sand on the inside of the chlorination tank 1. When the tower base 61 rotates, it can drive the top sleeve 67 to rotate together. With the cooperation of the mounting sleeve 68, the bottom plate 692, which is fixedly installed on the side wall of the sliding bent rod 69, will drive the stirring rod 693 to rotate, so as to realize the function of mixing the quartz sand in the chlorination tank 1. When the stirring motor 66 is running at high power, the top sleeve 67 will drive the mounting sleeve 68 to rotate at high speed. Under the action of centrifugal force of centrifugal plate 681 and sliding bent rod 69, the sliding bent rod 69 can move to the outside of the inner cavity of the mounting sleeve 68. At this time, the sliding bent rod 69 can change the stirring radius of the stirring rod 693 on the side wall of the bottom plate 692. Thus, through the above, this device can realize the mixing of quartz sand with different stirring ranges, improving the mixing quality of quartz sand in the whole device. When the top sleeve 67 rotates, the extension rod 71 fixed to its side wall can drive the cam block 72 to rotate. The cam block 72 can continuously press the abutment rod 76, causing the blocking block 75 to move left and right within the inner diameter of the control box 74. When the blocking block 75 slides into the left side of the inner cavity of the control box 74, the blocking block 75 will lose its ability to block the air outlet pipe 79 on the control box 74. At this time, the chlorine gas in the airbag ring 3 can enter the inner cavity of the connecting ring 78 through the air outlet pipe 79. Through the through hole 711 opened on the side wall of the extension rod 71, the chlorine gas in the inner cavity of the connecting ring 78 can pass through the extension rod 71 and the top sleeve 67. 7. The installation sleeve 68, sliding bent rod 69 and base plate 692 enter the inner cavity of the stirring rod 693, and finally exit from the air hole on the stirring rod 693 into the chlorination tank 1. With the stirring mechanism 6, the quartz sand and chlorine gas can be fully mixed, which greatly improves the efficiency of the whole device in chlorinating quartz sand (the cross-section of the barrier block 75 is set in a trapezoidal shape, so that the high pressure chlorine gas in the air bag ring 3 can impact the inclined surface of the barrier block 75, forming a partial downward force to increase the friction of the barrier block 75 and prevent the high pressure chlorine gas at the air inlet pipe 73 from squeezing the barrier block 75 and causing it to move). During the chlorination of quartz sand, the pressure relief valve installed in the inner cavity of the pressure relief pipe 5 is opened to periodically discharge the waste gas in the chlorination tank 1. At this time, the waste gas can enter the inner cavity of the purification box 81 through the pressure relief pipe 5 and mix with the calcium hydroxide solution in the purification box 81. The chlorine gas reacts with sodium hydroxide to produce sodium chloride, sodium hypochlorite and water. With the cooperation of the activated carbon plate 82, the toxic gases in the waste gas can be effectively absorbed, ensuring the health of the surrounding environment of the device.

Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of the present invention do not depart from the essence and scope of the technical solution of the present invention.
