Technical Field

[0001] This utility model relates to the field of high-purity quartz sand production technology, specifically a high-purity quartz sand flotation agent precision dosing device. Background Technology

[0002] Quartz sand is quartz particles produced by processing quartz stone through crushing and screening. Quartz stone is a non-metallic mineral, whose main mineral component is silicon dioxide (SiO2). Quartz sand can be classified according to quality into ordinary quartz sand, refined quartz sand, high-purity quartz sand, fused quartz sand, and silica powder, etc. The SiO2 content and impurity content vary among different types of quartz sand. For example, the SiO2 content of ordinary quartz sand is generally not less than 90%, while the SiO2 content of high-purity quartz sand is as high as 99.9% or more. Quartz sand plays an indispensable role in many key industrial fields, from basic glass manufacturing to high-tech semiconductor and photovoltaic industries, and is widely used. Especially in high-tech fields such as semiconductors and photovoltaics, high-purity quartz sand has become a key material for manufacturing core components such as integrated circuits and solar panels.

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] like Figs. 1-3The device for precisely adding high-purity quartz sand flotation reagent includes a reagent tank 1 and a flotation machine 2. A first feed port 10 is fixedly connected to the top of the reagent tank 1, and a reagent mixing mechanism 3 is provided in the reagent tank 1. A feed port 15 is connected to the top of the flotation machine 2, and an aeration and mixing mechanism 4 is provided in the flotation machine 2. The bottom of the reagent tank 1 is connected to the upper part of the flotation machine 2 through a conveying pipe 6. The bottom of the reagent tank 1 is inclined downwards towards the conveying pipe 6. In order to avoid the flotation reagent settling and causing changes in the concentration of the flotation reagent added to the flotation machine 2, a vibration plate 12 is fixedly connected to the bottom of the reagent tank 1. The vibration plate 12 is connected to an ultrasonic generator 13 fixedly connected to the outside of the reagent tank 1. A solenoid valve 7, a conveying pump 8, and a flow meter 9 are fixedly connected to the conveying pipe 6. A turbidity sensor 14 is fixedly connected to the middle of the flotation machine 2. A controller 5 is fixedly connected to the outside of the reagent tank 1. The turbidity sensor 14 and the flow meter 9 are communicatively connected to the controller 5. The solenoid valve 7 and the conveying pump 8 are controlled by the controller 5. It should be noted that in this embodiment, the turbidity sensor 14 is an existing component, and the communication connection between it and the controller 5 is existing technology. This application will not elaborate on its working principle. The vibration plate 12 and the ultrasonic generator 13 are existing devices, and this application will not explain their operating principle.

[0022] The working process of this embodiment is as follows: In the flotation process of high-purity quartz sand production, slurry is fed into the flotation machine 2 through the feed port 15. First, the turbidity target value of the slurry is set in the controller 5 according to the process. Flotation agent raw materials are fed into the reagent tank 1 through the first feed port 10. The reagent mixing mechanism 3 is started to run to mix and prepare the flotation agent. The ultrasonic generator 13 is started to drive the vibration plate 12 to vibrate, so as to ensure that the concentration of the added flotation agent is uniform and to avoid the flotation agent from settling and causing the concentration to change. The controller 5 opens the solenoid valve 7, controlling the operation of the transfer pump 8 and the flow meter 9. The transfer pump 8 extracts the flotation agent and enters the flotation machine 2 through the transfer pipe 6. Simultaneously, the aeration and mixing mechanism 4 is controlled to operate for flotation. During this process, the turbidity sensor 14 monitors the turbidity of the pulp in real time and feeds back the monitored turbidity data to the controller 5. When the monitored turbidity of the pulp is greater than the target value, the speed of the transfer pump 8 is increased to increase the amount of flotation agent added. When the monitored turbidity of the pulp is less than the target value, the speed of the transfer pump 8 is decreased to reduce the amount of flotation agent added, until the turbidity of the pulp tends to stabilize. The flow meter 9 can measure the flotation agent added to the flotation machine 2, and work together to achieve precise addition of flotation agent, avoiding problems such as waste of flotation agent or poor flotation effect due to insufficient addition.

[0023] To achieve uniform preparation of the flotation agent, the mixing mechanism 3 includes a stirring motor 302 and a stirring shaft 301. The stirring shaft 301 is rotatably connected to the mixing tank 1 via bearings. The upper end of the stirring shaft 301 is fixedly connected to the output shaft of the stirring motor 302, which is fixedly connected to the top of the mixing tank 1 via a connecting bracket and bolts. A mixing pipe 303 is fixedly connected to the top of the mixing tank 1. The lower end of the stirring shaft 301 passes through the top of the mixing pipe 303 and is fixedly connected to a connecting rod 306. The stirring shaft 301 and the mixing pipe 303 are connected via bearings and a sealing gasket. 06 has a U-shaped structure. Several stirring rods 307 are fixedly connected to the connecting rod 306. The stirring rods 307 will not interfere with the mixing pipe 303 during the rotation of the connecting rod 306. The stirring shaft 301 inside the mixing pipe 303 is fixedly connected to the auger blades 304. A gap of 1-3mm is left between the auger blades 304 and the inner wall of the mixing pipe 303. Several mixing holes 305 are opened on the mixing pipe 303. The top of the medicine tank 1 is fixedly connected to the second feeding port 11. The lower end of the second feeding port 11 is fixedly connected to the upper part of the mixing pipe 303 through a pipe.

[0024] The working process of this embodiment is as follows: When preparing the flotation agent, one raw material is first added through the first feeding port 10, and then another raw material is added through the second feeding port 11. The first raw material enters the preparation tank 1 and enters the mixing pipe 303 through the mixing hole 305. The second raw material enters the mixing pipe 303. The stirring motor 302 is started and runs. The stirring motor 302 drives the stirring shaft 301 to rotate. The stirring shaft 301 drives the auger blades 304 and the connecting rod 306 to rotate. Under the action of the auger blades 304, the second raw material and the first raw material are initially mixed and discharged from the mixing hole 305 into the preparation tank 1. The connecting rod 306 drives the stirring rod 307 to rotate, which can achieve full mixing of the two raw materials and prepare the flotation agent.

[0025] The aeration and mixing mechanism 4 includes a mixing motor 402, a hollow shaft 401, and an air pump 403. The hollow shaft 401 is rotatably connected to the flotation machine 2. The upper end of the hollow shaft 401 is fixedly connected to a rotary joint 404. The top of the rotary joint 404 is fixedly connected to the output end of the air pump 403 via a pipe. A driven bevel gear 406 is fixedly connected to the hollow shaft 401. A driving bevel gear 405 is fixedly connected to the output shaft of the mixing motor 402. The driving bevel gear 405 meshes with the driven bevel gear 406. A plurality of mixing blades are fixedly connected at intervals on the top of the aeration disc 407, and a plurality of ventilation holes are opened at the bottom. It should be noted that in this embodiment, the air pump 403 can also be replaced by a variable frequency blower.

[0026] The working process of this embodiment is as follows: During flotation, the mixing motor 402 is controlled to operate, driving the driving bevel gear 405 to rotate. The driving bevel gear 405 and the driven bevel gear 406 mesh to drive the hollow shaft 401 to rotate, which in turn drives the aeration disc 407 to rotate. The mixing blades at the upper end of the aeration disc 407 stir and contact the slurry and flotation agent. Simultaneously, the air pump 403 is started, blowing air into the hollow shaft 401 and exhausting air through the vent at the bottom of the aeration disc 407. The air bubbles carry impurities to the surface for flotation. During this process, the speed of the mixing motor 402 and the air output of the air pump 403 can be adjusted to regulate the flotation effect.

[0027] For flotation, a flotation cell 18 is fixedly connected to one side of the flotation machine 2. A feeding shaft is rotatably connected inside the flotation cell 18, and a feeding plate is fixedly connected to the feeding shaft. One end of the feeding shaft is fixedly connected to the output shaft of a drive motor fixedly connected to one side of the flotation cell. A collection box 23 is provided at the lower end of the flotation cell 18. It should be noted that, in this embodiment, when feeding the slurry, the slurry level does not exceed half of the feeding plate inside the flotation cell 18.

[0028] The working process of this embodiment is as follows: When flotation is performed, the drive motor is started and runs. The drive motor drives the feeding shaft to rotate, and the feeding shaft drives the feeding plate to rotate, which agitates the foam floating on the surface of the slurry, causing it to leave the flotation cell 18 and fall into the impurity collection box 23.

[0029] To ensure that the bubbles rise evenly during the flotation process, a uniform material plate 408 is fixedly connected to the middle of the flotation machine 2, and the uniform material plate 408 has several through holes.

[0030] The working process of this embodiment is as follows: During the flotation process, bubbles carrying impurities rise through the uniform plate 408, which can achieve full flotation.

[0031] To ensure that the flotation agent can be added to the slurry evenly, a spray plate 16 is fixedly connected to the end of the conveying pipe 6, and the spray plate 16 is inclined along the body of the flotation machine 2.

[0032] The working process of this embodiment is as follows: When flotation agent is added into the flotation machine 2, the flotation agent is sprayed from the conveying pipe 6 through the spray plate 16 into the flotation machine 2.

[0033] To ensure a stable supply of slurry to the flotation machine 2 and to prevent problems such as clogging of the feed plate 16 caused by the addition of slurry, an inclined guide plate 17 is fixedly connected to one side of the flotation machine 2 directly below the feed inlet 15.

[0034] The working process of this embodiment is as follows: When the slurry is added, it enters from the feed port 15 and slides down from the guide plate 17 into the flotation machine 2.

[0035] To facilitate material discharge and slag removal, a discharge pipe 19 is fixedly connected to one side of the lower part of the flotation machine 2, and a discharge valve 20 is fixedly connected to the discharge pipe 19. A slag discharge pipe 21 is fixedly connected to the bottom of the flotation machine 2, and a slag discharge valve 22 is fixedly connected to the slag discharge pipe 21.

After the discharge, the residue at the bottom of the flotation machine 2 can be discharged through the discharge pipe 21 by opening the discharge valve 22.

[0037] It should be noted that, in this embodiment, in order to ensure the preparation effect of the flotation agent, a jacket is fixedly connected to the outside of the preparation tank 1, and an electric heating wire is provided inside the jacket to heat the preparation tank 1 and ensure the uniformity of the flotation agent preparation.

[0038] The working principle of this embodiment is as follows: When performing flotation for high-purity quartz sand production, the flotation agent is first uniformly prepared in the reagent mixing tank 1 using the reagent mixing and stirring mechanism 3. The ultrasonic generator 13 and the vibration plate 12 are used to prevent the flotation agent from settling. After preparation, the flotation agent is transported to the flotation machine 2 using the delivery pump 8 and the delivery pipe 6. The aeration and mixing mechanism 4 is used to carry out the flotation of the slurry. During the flotation process, the turbidity of the slurry is monitored in real time using the turbidity sensor 14, and the controller 5 is used to achieve precise addition of the flotation agent.
