Description

Technical Field

[0001] This application relates to the field of impurity removal equipment, and more specifically, to a directional impurity removal device and process for industrial silicon smelting of organosilicon. Background Technology

[0002] Industrial silicon is a very important raw material, widely used in electronics, optoelectronics, medicine, chemical industry and other fields. However, freshly mined silicon sand contains certain soil impurities, so it is necessary to first remove the soil impurities from the silicon sand in a targeted manner.

[0003] Currently, water washing is a relatively simple and effective method for removing soil impurities from silica sand. Therefore, drum washing is often used. However, there are often hard soil lumps in silica sand, and these hard soil lumps cannot be quickly dissolved into muddy water. As a result, soil lumps often remain in the silica sand after washing, which reduces the cleanliness of the silica sand after washing. Summary of the Invention

[0004] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a directional impurity removal device for industrial silicon smelting of organosilicon, which can crush silica sand by using multiple crushing rollers and turning brushes in combination to repeatedly crush and turn the silica sand, thereby crushing the hard mud lumps in the silica sand. During the washing process, the mud lumps can be quickly decomposed into muddy water. Therefore, after the muddy water is discharged, the mud content in the silica sand is reduced, further improving the cleanliness of the washed silica sand.

[0005] A directional impurity removal device for industrial silicon smelting of organosilicon according to an embodiment of this application includes: an equipment frame, a mud crushing component, and a washing component.

[0011] According to this application, a second hopper is provided on one side of the equipment frame, the bottom of the second hopper extends to the inside of the box, and a nozzle is provided at the output end of the first water pump. The nozzle is fixedly connected to the equipment frame, and the output end of the nozzle faces the inside of the box.

[0012] According to this application, the first conveying bucket includes a first outer bucket, a first screw rod, and a third motor. The bottom of the first outer bucket is fixedly connected to the bottom of the inner side of the receiving box, the upper part of the first outer bucket is fixedly connected to the inner side of the first hopper, the first screw rod is rotatably connected to the inside of the first outer bucket, the third motor is fixedly connected to the first outer bucket, and the output end of the third motor is fixedly connected to one end of the first screw rod.

[0013] According to this application, the rotating cleaning tank includes a tank body, a spiral plate, and a fourth motor. The tank body is rotatably connected to the equipment frame, the spiral plate is fixedly connected inside the tank body, the fourth motor is fixedly connected to the equipment frame, the output end of the fourth motor is drively connected to the tank body, and the discharge end of the first hopper extends into the inside of the tank body.

[0014] According to this application, a material nozzle is provided on the side of the barrel away from the first hopper. The material nozzle is fixedly connected to the equipment frame and rotatably connected to one side of the barrel. The bottom of the material nozzle extends to the upper part of the conveying end of the water control conveyor.

[0015] Washing can effectively remove dirt from silica sand, but the washed silica sand contains a lot of water. Often, the washed silica sand is directly piled on the ground or loaded onto trucks for transport. If it is piled on the ground, the water in the silica sand will flow to the perimeter of the pile, making it difficult to load. If it is loaded onto trucks, the silica sand will flow from the truck bed onto the ground, which will interfere with the transportation route. The main problem is that whether it is piled on the ground or loaded onto trucks for transport, water will flow onto the ground, resulting in a waste of water resources.

[0016] According to this application, a dewatering assembly is also included, comprising a second outer barrel, a second conveying barrel, a rotating dewatering screen barrel, an inner baffle, a pusher plate, a horizontal pusher, a second telescopic member, and a connecting frame. The second outer barrel is fixedly connected to one side of the equipment frame. The rotating dewatering screen barrel is rotatably connected to the inside of the second outer barrel. The second conveying barrel is fixedly connected to the equipment frame. One side of the second conveying barrel is located below the output end of the water control conveyor. The second conveying barrel extends to the middle of the inner side of the rotating dewatering screen barrel. Multiple inner baffles are spaced apart and fixedly connected to the inner wall of the rotating dewatering screen barrel. The pusher plate has a through groove. The inner baffle is slidably connected to the outside of the through groove. The periphery of the pusher plate is slidably connected to the inner wall of the rotating dewatering screen barrel. One end of the horizontal pusher is fixedly connected to one side of the pusher plate. The other end of the horizontal pusher is rotatably connected to the connecting frame. The connecting frame is slidably connected to the equipment frame. One side of the second telescopic member is fixedly connected to the equipment frame. The output end of the second telescopic member is fixedly connected to one side of the connecting frame. The second telescopic members are symmetrically arranged.

[0017] After being cleaned in the rotating washing tank, the silica sand is discharged to the conveying end of the water-controlled conveyor. The conveyor then transports the silica sand to the inlet end of the second feeding tank, which in turn transports it to the inner center of the rotating dewatering screen tank. The rotation of the screen tank at this point causes the water in the silica sand to be ejected, similar to the spin-drying function of a washing machine, transferring the water to the inside of the second outer tank. Because the rotating screen tank dewaters the silica sand, it adheres to the inner wall of the screen tank under centrifugal force. Furthermore, the rotation of the screen tank causes the pusher plate to rotate synchronously. Simultaneously, the telescopic end of the second telescopic component drives the connecting frame to move laterally. Since the connecting frame and the horizontal pusher are rotatably connected, the output end of the second telescopic component, which moves the connecting frame, causes the horizontal pusher to move as well. The horizontal pusher moves the pusher plate, pushing the silica sand adhering to the inner wall of the rotating dewatering drum back and forth. Therefore, the dewatered silica sand is pushed to both sides of the rotating dewatering drum, allowing for continuous rotation and dewatering. Many commonly used dewatering devices, similar to those used in washing machines, remove the dewatered items after dewatering and then place another item for dewatering, making continuous dewatering inconvenient. Therefore, by utilizing the second telescopic component, connecting frame, horizontal pusher, and pusher plate in combination, continuous dewatering of the silica sand is achieved, improving dewatering efficiency, reducing water loss during silica sand stacking and transportation, and allowing for the recycling of dewatered water, thus reducing water waste.

[0018] According to this application, the second conveying bucket includes a receiving hopper, a third outer bucket, a second screw rod, and a fifth motor. The receiving hopper is located below the output end of the water control conveyor. The bottom of the receiving hopper is fixedly connected to the third outer bucket. The third outer bucket is fixedly connected to the equipment frame. The second screw rod is rotatably connected to the inside of the third outer bucket. The fifth motor is fixedly connected to one side of the third outer bucket. The output end of the fifth motor is fixedly connected to one end of the second screw rod.

[0019] According to this application, the rotating dewatering mesh barrel includes a mesh barrel body and a sixth motor. The inner baffle is fixedly connected to the inner wall of the mesh barrel body. The outer side of the pusher plate is slidably connected to the inner wall of the mesh barrel body. The sixth motor is fixedly connected to the equipment frame. The mesh barrel body is rotatably connected to the inside of the second outer barrel. The output end of the sixth motor is drively connected to the mesh barrel body.

[0020] According to this application, a limiting ring is provided on the side of the horizontal pusher away from the pusher plate, and a limiting groove is provided on the connecting frame, with the limiting ring rotatably connected inside the limiting groove.

[0021] Some small mines discharge the washing water directly after washing silica sand, without timely simple treatment and reuse of the water, thus reducing the utilization rate of water resources.

[0022] According to this application, a circulating water assembly is also included, comprising a first water tank, a second water pump, a flocculation tank, a filter box, a rotating filter screen, a brush roller, a second water tank, and a third conveying bucket. The first water tank is located below the water control conveyor and is fixedly connected to the equipment frame. The input end of the second water pump is connected to the bottom of the first water tank and the second outer bucket, respectively. The output end of the second water pump is connected to the upper interior of the flocculation tank. The flocculation tank is fixedly connected to the equipment frame. The bottom of the flocculation tank is connected to the interior of the filter box. The rotating filter screen is rotatably connected to the interior of the filter box. The bottom of the filter box is fixedly connected to the interior of the second water tank. The second water tank is fixedly connected to the equipment frame. The rotating end of the brush roller is close to the filtering end of the rotating filter screen. The bottom of the filter box is connected to the second water tank. The third conveying bucket is fixedly connected to the equipment frame. The bottom of the third conveying bucket is close to the filtering end of the rotating filter screen. The input end of the first water pump is connected to the second water tank.

[0023] When the water control conveyor conveys and controls the water for the cleaned silica sand, the controlled water flows into the first water tank. When the rotating dewatering screen dewaters the silica sand, the dewatered water enters the bottom of the second outer tank. The bottoms of both the first water tank and the second outer tank are connected to the input end of the second water pump. The second water pump delivers water to the flocculation tank, where flocculants are added to treat the wastewater. The flocculated water flows into the filter tank and is filtered by a rotating screen. The filtered water then flows into the second water tank. The input end of the first water pump delivers water to the first hopper, achieving rapid water recycling. When the rotating screen filters the flocculated water, impurities in the water are filtered to the upper periphery of the rotating screen. The rotating screen continues to rotate, and the brush rollers rotate and brush the impurities on the surface of the rotating screen to the bottom edge of the rotating screen. At this time, the third conveying tank quickly discharges the impurities. Throughout the entire process, rapid treatment of the water used for cleaning silica sand is achieved, improving the water recycling rate.

[0024] According to this application, the rotating filter screen includes a seventh motor and a conical mesh body. The seventh motor is fixedly connected to the bottom of the filter box, and the output end of the seventh motor is fixedly connected to the conical mesh body. The conical mesh body is rotatably connected to the filter box, and the third conveying bucket has a similar structure to the first conveying bucket.

[0025] According to this application, the brush roller includes a bracket, an eighth motor, and a second brush body.

[0026] A purification process according to a second aspect of this application includes a directional purification apparatus for industrial silicon smelting of organosilicon as described in a first aspect of this application, and the following steps:

[0027] S1. Silica sand is laid flat inside the rotating box. As the rotating box continues to rotate, the silica sand laid flat inside the rotating box is rotated to the bottom of the crushing roller. The crushing roller presses down on the silica sand. The pressed silica sand is then rotated to the bottom of the turning brush. The turning brush turns up the pressed silica sand. After being pressed down and turned up by multiple crushing rollers and turning brushes, the mud inside the silica sand is crushed.

[0028] S2. When the crushed mud and silica sand reach the top of the receiving box, they will enter the receiving box through the through hole, and under the action of a turning brush, all the crushed mud and silica sand will enter the receiving box.

[0029] S3. The first conveying bucket transports the silica sand and soil inside the receiving box to the first hopper. At this time, the first water pump delivers the cleaning water to the first hopper. The silica sand and cleaning water are then transported together to the rotating cleaning bucket through the first hopper. The rotation of the rotating cleaning bucket cleans the silica sand.

[0030] S4. The cleaned silica sand and water are discharged and directed to the upper part of the conveying end of the water control conveyor. The silica sand is conveyed and water is controlled simultaneously by the water control conveyor before being conveyed to the next process.

[0031] The beneficial effects of a directional impurity removal apparatus for industrial silicon smelting of organosilicon according to an embodiment of this application are:

[0032] 1. First, the silica sand is placed inside the rotating box. The rotation of the rotating box causes the silica sand to rotate, moving it under the crushing roller. The crushing roller applies downward pressure to the silica sand. After being crushed, the silica sand is rotated by the rotating box to the underside of the turning brush. The turning brush rotates and turns the silica sand. The silica sand then rotates to the underside of the next crushing roller, where it is pressed down again. After being turned over by another turning brush, the silica sand is crushed by the action of multiple crushing rollers and turning brushes, making it easier to clean later.

[0033] 2. After being repeatedly crushed, the silica sand is rotated by the rotating box to the top of the receiving box. At this point, the through-hole in the rotating box connects the rotating box and the receiving box. A rotating brush then passes through the through-hole into the receiving box. The first conveying hopper transports the silica sand from the receiving box to the first hopper, while the first water pump delivers water to the first hopper. The first hopper then transports the silica sand and water into the rotating washing tank, where it is washed. During this process, the water washes away the crushed soil. The lumps dissolve into a muddy slurry. The washed silica sand and water are then directed to the bottom conveyor of the water-controlled conveyor. The conveyor and baffle of the water-controlled conveyor have fine holes, so when the water-controlled conveyor transports the silica sand, it controls out some of the water inside the silica sand. During the entire process, the hard mud lumps in the silica sand are crushed. Therefore, when the silica sand is washed inside the rotating washing tank, the mud can be quickly dissolved in the water to form a muddy slurry, which facilitates the washing of the silica sand, reduces the mud lumps contained in the silica sand, and thus improves the cleanliness of the silica sand after washing.

[0048] The mud crushing assembly 200 includes a bottom box 210, a rotating box 220, a receiving box 230, crushing rollers 240, and turning brushes 250. The rotating box 220 has through holes spaced apart at its bottom. Both the bottom box 210 and the receiving box 230 are fixedly connected to the upper part of one side of the equipment frame 100. One side of the receiving box 230 communicates with the interior of the bottom box 210. The rotating box 220 is rotatably connected to the interior of the bottom box 210. Multiple crushing rollers 240 and turning brushes 250 are spaced apart. Both crushing rollers 240 and turning brushes 250 are fixedly connected to the equipment frame 100. The rotating ends of the crushing rollers 240 and turning brushes 250 extend into the interior of one side of the rotating box 220, and are close to the bottom inner side of the rotating box 220. The cleaning assembly 300 includes a first water pump 31. 0. A first feeding bucket 320, a first hopper 330, a rotating washing bucket 340, and a water control conveyor 350 are provided. The conveying end of the water control conveyor 350 is provided with baffles 351 at intervals. Both the baffles 351 and the conveying end of the water control conveyor 350 are provided with small holes at intervals. The first water pump 310 and the first hopper 330 are fixedly connected to the equipment frame 100. The discharge end of the first hopper 330 is connected to the interior of one side of the rotating washing bucket 340. The rotating washing bucket 340 is rotatably connected to the equipment frame 100. The water control conveyor 350 is located below the output end of the rotating washing bucket 340. The bottom of the first feeding bucket 320 is connected to the interior of the receiving box 230. The output end of the first feeding bucket 320 is connected to the interior of the first hopper 330. The output end of the first water pump 310 is connected to the inner side of the first hopper 330.

[0049] The working process of a directional impurity removal device for industrial silicon smelting of organosilicon according to a specific embodiment of this application is described below with reference to the accompanying drawings.

[0050] First, the silica sand is conveyed into the box 222 through the second hopper 110. The output end of the first motor 221 drives the box 222 to rotate, conveying the silica sand to the bottom of the roller 244. The lifting end of the first lifting frame 241 drives the first upright frame 242 and spring 243 to descend, pressing down on the silica sand and crushing the soil lumps in the silica sand. Then, the silica sand is rotated to the bottom of the first brush 253. The output end of the second motor 254 drives the first brush 253 to rotate, turning the pressed silica sand over. Through the combined use of multiple rollers 244 and the first brush 253, the silica sand is crushed and turned over.

[0051] Then, the output end of the first motor 221 drives the box 222 to rotate continuously, rotating the silica sand to the top of the receiving box 230. At this time, the box 222 is connected to the receiving box 230 through the through hole, and the silica sand enters the receiving box 230 through the through hole.

[0052] Next, the first conveying hopper 320 conveys the silica sand inside the receiving box 230 to the first hopper 330. The output end of the first water pump 310 conveys water to the first hopper 330. At the same time, the output end of the first water pump 310 conveys water to the nozzle 311. The nozzle 311 sprays water on the silica sand inside the box 222, which can reduce dust and wet the silica sand at the same time, effectively preventing dust from being generated during the turning process. The first hopper 330 conveys water and silica sand to the rotating cleaning tank 340, where the silica sand is cleaned.

[0053] Finally, the cleaned silica sand is discharged from the inside of the rotating cleaning tank 340. At this time, the soil in the silica sand will be dissolved in the water to form mud water. The silica sand and mud water are discharged into the feed nozzle. The feed nozzle guides the silica sand and mud water to the conveying end of the water control conveyor 350. The water control conveyor 350 conveys the silica sand and controls the water.

[0054] Therefore, during the entire process of use, the hard soil lumps in the silica sand are crushed. Thus, when the silica sand is cleaned inside the rotating washing tank 340, the soil can be quickly dissolved in the water to form mud slurry, which facilitates the cleaning of the silica sand, reduces the soil lumps contained in the silica sand, and thus improves the cleanliness of the silica sand after cleaning.

[0064] Washing can effectively remove dirt from silica sand, but the washed silica sand contains a lot of water. Often, the washed silica sand is directly piled on the ground or loaded onto trucks for transport. When piled on the ground, the water in the silica sand will flow to the perimeter of the pile, making loading difficult. When loaded onto trucks, the water in the silica sand will flow from the truck bed onto the ground, interfering with the transportation route. The main problem is that whether piled on the ground or loaded onto trucks for transport, water will flow onto the ground, resulting in a waste of water resources.

[0065] According to this application, such as Figures 6-7 As shown, it also includes a dewatering assembly 400, which includes a second outer barrel 410, a second conveying barrel 420, a rotating dewatering screen barrel 430, an inner baffle 440, a pusher plate 450, a horizontal pusher frame 460, a second telescopic member 470, and a connecting frame 480. The second outer barrel 410 is fixedly connected to one side of the equipment frame 100. The rotating dewatering screen barrel 430 is rotatably connected to the inside of the second outer barrel 410. The second conveying barrel 420 is fixedly connected to the equipment frame 100. One side of the second conveying barrel 420 is located below the output end of the water control conveyor 350. The second conveying barrel 420 extends to the middle of the inner side of the rotating dewatering screen barrel 430. The inner baffle 440 is spaced apart. Multiple inner baffles 440 are fixedly connected to the inner wall of the rotating dewatering screen 430. The pusher plate 450 has a through groove 451. The inner baffle 440 is slidably connected to the outside of the through groove 451. The periphery of the pusher plate 450 is slidably connected to the inner wall of the rotating dewatering screen 430. One end of the horizontal pusher 460 is fixedly connected to one side of the pusher plate 450. The other end of the horizontal pusher 460 is rotatably connected to the connecting frame 480. The connecting frame 480 is slidably connected to the equipment frame 100. One side of the second telescopic member 470 is fixedly connected to the equipment frame 100. The output end of the second telescopic member 470 is fixedly connected to one side of the connecting frame 480. The second telescopic members 470 are symmetrically arranged.

[0066] After being cleaned by the rotating washing tank 340, the silica sand is discharged to the conveying end of the water control conveyor 350. The conveying end of the water control conveyor 350 transports the silica sand to the feeding end of the second feeding tank 420. The second feeding tank 420 transports the silica sand to the inner middle of the rotating dewatering screen tank 430. At this time, the rotation of the rotating dewatering screen tank 430 throws out the water from the silica sand, similar to the spin-drying function of a washing machine, dewatering the silica sand into the second outer tank 410. Because the rotating dewatering screen tank 430 rotates and dewaters the silica sand, the silica sand will adhere to the inner wall of the rotating dewatering screen tank 430 under the action of centrifugal force. The rotation of the rotating dewatering screen tank 430 will drive the pusher plate 450 to rotate synchronously. At this time, the telescopic end of the second telescopic member 470 drives the connecting frame 480 to move laterally. The connecting frame 480 is rotatably connected to the horizontal pusher frame 460. Therefore, the output end of the second telescopic member 470 drives the connecting frame 480 to move laterally. The movement of the horizontal pusher 460 causes the horizontal pusher 460 to move, which in turn drives the pusher plate 450 to move, pushing the silica sand adhering to the inner wall of the rotating dewatering screen 430 back and forth. Therefore, the dewatered silica sand is pushed to both sides of the rotating dewatering screen 430, and continuous rotation dewatering can be achieved. Many commonly used dewatering equipment, similar to the dewatering function of a washing machine, removes the dewatered items after dewatering and then places another item for dewatering, which is not convenient for continuous dewatering operations. Therefore, in the whole process of use, by using the cooperation of the second telescopic component 470, the connecting frame 480, the horizontal pusher 460 and the pusher plate 450, continuous dewatering operation can be achieved while dewatering silica sand, thereby improving the dewatering efficiency, reducing water outflow during the stacking and transportation of silica sand, and allowing the dewatered water to be recycled, thereby reducing the waste of water resources.

[0070] Some small mines discharge the washing water directly after washing silica sand, failing to treat and reuse the water in a timely manner, thus reducing the utilization rate of water resources.

[0072] When the water conveyor 350 conveys and controls the water in the cleaned silica sand, the controlled water flows into the first water tank 510. When the dewatering screen 430 dewaters the silica sand, the dewatered water enters the bottom of the second outer tank 410. The bottoms of both the first water tank 510 and the second outer tank 410 are connected to the input end of the second water pump 520. The second water pump 520 delivers water to the flocculation tank 530, where flocculant is added to treat the wastewater. The flocculated water flows into the filter tank 540 and is filtered by the rotating filter screen 550. The water flows into the second water tank 570, and the input end of the first water pump 310 delivers the water to the first hopper 330, realizing rapid water recycling. When the rotating filter screen 550 filters the flocculated water, the impurities in the water are filtered to the upper periphery of the rotating filter screen 550. At this time, the rotating filter screen 550 continues to rotate, and the brush roller 560 rotates and brushes the impurities on the surface of the rotating filter screen 550 to the bottom edge of the rotating filter screen 550. At this time, the third conveying bucket 580 quickly discharges the impurities. In the whole process, the water used for cleaning silica sand is rapidly treated, and the water recycling rate is improved.

As the rotating box 220 continues to rotate, the silica sand laid flat inside the rotating box 220 is rotated to the bottom of the crushing roller 240. The crushing roller 240 presses down on the silica sand. Then, the pressed silica sand is rotated to the bottom of the turning brush 250. The turning brush 250 turns up the pressed silica sand. After being pressed down and turned up by multiple crushing rollers 240 and turning brush 250, the mud inside the silica sand is crushed.

[0077] S2. When the crushed mud and silica sand reach the top of the receiving box 230, they will enter the receiving box 230 through the through hole, and under the action of a flipping brush 250, all the crushed mud and silica sand will enter the receiving box 230.
