Description

Technical Field

[0001] The utility model belongs to the field of quartz sand preparation, and particularly relates to a quartz sand purification flotation device. Background Art

[0002] Quartz sand is quartz particles obtained by crushing quartz stone. Quartz sand is an important industrial mineral raw material and is widely used in industries such as glass, casting, ceramics and fireproof materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives, filter media, etc. In the process of quartz sand preparation, since impurities are doped after the quartz stone is crushed, it is necessary to purify the quartz sand to remove mineral impurities in the quartz sand to obtain high-purity quartz sand. Among them, the common method is to separate the quartz sand from the impurities by flotation, mainly to remove associated mineral impurities such as feldspar and mica. However, impurities are also introduced during the production process of quartz sand, and these impurities are difficult to separate by flotation. Therefore, even through multiple flotation operations, the separation is not complete, and it will affect the removal of mineral impurities. Summary of the Utility Model

[0003] Aiming at the above deficiencies, the utility model provides a quartz sand purification flotation device, which can improve the purification effect of quartz sand.

[0004] The utility model is realized by the following technical solutions:

[0005] A quartz sand purification flotation device, the flotation device includes a first flotation component and a second flotation component arranged in sequence. The first flotation component includes a flotation machine with an accommodation space formed therein and a stirring member arranged in the accommodation space. A water replenishing member and a medicine replenishing member communicating the accommodation space with the outside are arranged at the flotation machine. The first flotation component further includes a scraper arranged at the flotation machine. The scraper is located at the opening of the accommodation space and can rotate relative to the flotation machine. The structure of the second flotation component is the same as that of the first flotation component. Among them, an acid pickling component is further arranged between the first flotation component and the second flotation component. The acid pickling component includes a feed inlet communicating with the first flotation component and a discharge outlet communicating with the second flotation component, so that the quartz sand at the first flotation component is transported to the second flotation component after passing through the acid pickling component. By arranging the acid pickling component during the flotation process, during the flotation process, the acid pickling component removes the impurities that are difficult to handle during the flotation process, so as to reduce the burden on the second flotation component to remove impurities by flotation. At the same time, after the impurities are further removed by the acid pickling component, the amount of impurities in the quartz sand after reaching the second flotation component will also be reduced, which can also improve the separation efficiency of the second flotation component for quartz sand and has a better purification effect on quartz sand.

[0006] Furthermore, the stirring member includes a stirring shaft coaxially arranged with the flotation machine and a stirring member connected to the stirring shaft, and the stirring member is provided with a plurality of through holes. During the flotation process of quartz sand, the stirring member rotates continuously, which can not only make the added medicament mix more evenly, but also make the impurities suspended under stirring, which is more conducive to the separation of impurities. For the stirring member, having a plurality of through holes thereon also facilitates the flow of liquid to better remove impurities and purify the quartz sand.

[0007] Furthermore, the stirring shaft is hollowly arranged so that the inside of the stirring shaft communicates with the accommodating space, and the medicament supplement member is connected to the inside of the stirring shaft. Since it is necessary to add medicament into the accommodating space during the flotation process to combine with the impurities in the quartz sand, connecting the medicament supplement member to the inside of the stirring shaft enables the medicament to quickly reach the bottom of the accommodating space to combine with the impurities in the quartz sand after adding the medicament, making the cleaning more convenient.

[0008] Furthermore, the scraper includes a rotating shaft connected to the flotation machine and a plurality of plate bodies circumferentially distributed along the rotating shaft. Since the scraper removes the floating impurities by rotation, by arranging a plurality of plate bodies and the plate bodies being circumferentially distributed along the rotating shaft, during the rotation of the rotating shaft, the plate bodies can be continuously driven to rotate, thereby realizing the continuous removal of impurities, avoiding the accumulation of impurities, and at the same time facilitating the impurities to be exposed above the water surface in time for convenient removal of the impurities.

[0009] Furthermore, the accommodating space is filled with flotation liquid, the plate body has a scraping section immersed in the flotation liquid and a connecting section connecting the scraping section and the rotating shaft, and the ratio of the length of the scraping section to the length of the connecting section is 1:3 to 1:5. If the ratio of the length of the scraping section to the length of the connecting section is too large, that is, the length of the scraping section is too long, the immersed length of the scraping section increases, and the resistance during rotation will also increase. If the ratio of the length of the scraping section to the length of the connecting section is too small, that is, the length of the scraping section is too short, it is easy to cause incomplete cleaning of the impurities.

[0010] Further, the replenishing component includes an infusion tube located above the accommodation space and a communication valve provided at the infusion tube. The infusion tube includes a first infusion section communicating with the accommodation space and a second infusion section communicating with the first infusion section. The second infusion section is arranged to be inclined upward relative to the first infusion section, and the communication valve is provided at the second infusion section. The first infusion section communicates with the accommodation space, that is, the first infusion section is the part connected to the stirring shaft, and the second infusion section is the part extending outward from the first infusion section, so as to facilitate the connection of the second infusion section to the outside. At the same time, for the second infusion section, since it is arranged to be inclined upward relative to the first infusion section, the second infusion section will be farther away from the horizontal plane, thus avoiding the collision between the scraper and the second infusion section when removing impurities through the scraper. At the same time, the communication valve is provided at the second infusion section. Therefore, with the second infusion section arranged to be inclined upward, it is also more convenient to operate the communication valve, so as to realize the opening and closing of the second infusion section and the flow rate, and stably control the water addition amount in the flotation process.

[0011] Further, the flotation machine includes a main body having an accommodation space formed therein and a cover body provided on the upper side of the main body. An opening communicating with the accommodation space is provided in the cover body, and the stirring member is located at the side of the opening. Since the flotation machine separates quartz sand from impurities, by providing a cover body on the upper side of the main body, a certain blockage is formed for the accommodation space formed in the main body, thereby preventing foreign impurities from entering. At the same time, an opening is provided in the cover body, which can not only put quartz sand in, but also ensure that the stirring member can remove impurities from the opening.

[0012] Further, the cross-sectional shape of the main body in the horizontal direction is a polygon. Since the cover body is located on the upper side of the main body, the cross-sectional shape of the main body in the horizontal direction is a polygon, and correspondingly, the cross-sectional shape of the cover body in the horizontal direction is also a polygon. This not only facilitates the opening of the opening in the cover body, but also makes the boundary between the opening and the adjacent part more obvious, and is more convenient for the setting and installation of the stirring member.

[0013] Further, the pickling assembly includes a dehydration assembly communicating with the first flotation assembly and a deacidification assembly communicating with the second flotation assembly. An acid leaching assembly is also provided between the dehydration assembly and the deacidification assembly. By providing the dehydration assembly, the moisture attached to the first flotation assembly can be removed during acid leaching to facilitate subsequent processing. After the acid leaching is completed, it is processed by the deacidification assembly, and then the quartz sand is transported to the second flotation assembly for secondary flotation processing.

[0021] In addition, it should also be noted that the dynamic terms such as "relative movement" mentioned in the embodiments of the present utility model not only refer to the change in position, but also include movements such as rotation and rolling where the position does not change relatively, but the state changes.

[0022] Finally, it should be noted that when a component is referred to as being "located" or "disposed on" another component, it can be on the other component or there may be an intermediate component at the same time. When a component is referred to as being "connected to" another component, it can be directly connected to the other component or there may be an intermediate component at the same time.

[0023] Such as Figures 1 to 3A quartz sand purification flotation device is shown. The flotation device includes a first flotation component 1 and a second flotation component 2 arranged in sequence. The first flotation component 1 includes a flotation machine 11 having an accommodation space and a stirring member 12 disposed in the accommodation space. A water replenishing member and a medicine replenishing member 15 communicating the accommodation space with the outside are provided at the flotation machine 11. The first flotation component 1 further includes a scraper disposed at the flotation machine 11. The scraper is located at the opening of the accommodation space and can rotate relative to the flotation machine 11. The structure of the second flotation component 2 is the same as that of the first flotation component 1. Among them, an acid pickling component is further provided between the first flotation component 1 and the second flotation component 2. The acid pickling component includes a feed port communicating with the first flotation component 1 and a discharge port communicating with the second flotation component 2, so that the quartz sand at the first flotation component 1 is conveyed to the second flotation component 2 after passing through the acid pickling component. Among them, in the process of preparing quartz sand, since impurities will be doped, it is necessary to purify the quartz sand to remove mineral impurities in the quartz sand to obtain high-purity quartz sand. In this application, the quartz sand is purified by flotation, and the flotation process will be carried out through the first flotation component 1 and the second flotation component 2, and an acid pickling component is also provided for acid pickling treatment between the two flotations. That is, after the first flotation is carried out by the first flotation component 1, the quartz sand will be conveyed to the acid pickling component for acid pickling treatment, and then conveyed to the second flotation component 2 for the second flotation. Therefore, compared with directly carrying out multiple flotations, in this application, by setting an acid pickling component in the flotation process, during the flotation process, the acid pickling component removes the impurities that are difficult to handle during the flotation process, so as to reduce the burden on the second flotation component 2 to remove impurities by flotation. At the same time, after the acid pickling component further removes the impurities, the amount of impurities in the quartz sand after reaching the second flotation component 2 will also be reduced, which can also improve the separation efficiency of the second flotation component 2 for the quartz sand, and the purification effect of the quartz sand is better.

[0024] In this application, the flotation machine 11 with an accommodation space formed in the first flotation assembly 1 is used to accommodate quartz sand. At the same time, the medicine supplementing member 15 communicates with the accommodation space to be able to convey liquid medicine into the accommodation space to separate the quartz sand from impurities. When separating impurities by adding medicine into the accommodation space, water is continuously conveyed by the water supplementing member to make the impurities float and overflow to the outside of the accommodation space, thereby realizing the separation of quartz sand and impurities. At the same time, a rotatable scraper is also provided at the flotation machine 11. By rotating the scraper, the floating impurities can be scraped off, making the separation of impurities faster. At the same time, when the scraper removes the floating impurities, the water level in the scraping area will drop briefly, causing the floating impurities in the periphery to move towards the scraper, facilitating the effective removal of the floating impurities by the scraper. Among them, the structure of the second flotation assembly 2 is the same as that of the first flotation assembly 1. Therefore, the first flotation assembly 1 will be described in detail as an example. The treatment of quartz sand by the second flotation assembly 2 can refer to the first flotation assembly 1. At the same time, the selection of the medicine can refer to the medicine added during flotation in the prior art, which will not be elaborated here.

[0025] It can be understood that when purifying quartz sand in this application, the water supplementing member continuously conveys water into the accommodation space. Therefore, the excess water will continuously overflow from the opening of the accommodation space. The impurities in the quartz sand will also float after combining with the medicine. Therefore, when the water overflows, it will also carry the floating impurities out together, thereby cleaning the impurities at the opening of the accommodation space together with the scraper, and at the same time, the impurities will not be hindered when floating, making the cleaning more thorough.

[0026] In this application, a waste residue collection port 16 is also provided. The overflowed waste residue can be discharged through the waste residue collection port 16 and collected subsequently, so that the waste residue can be discharged in time to avoid waste residue accumulation. At the same time, the timely discharge of the waste residue can also make the waste residue continuously overflow, thereby improving the purity of the quartz sand after flotation.

[0027] As an implementation mode in this application, the stirring member 12 includes a stirring shaft coaxially arranged with the flotation machine 11 and a stirring member 12 connected to the stirring shaft. The stirring member 12 is provided with a plurality of through holes. During the flotation process of quartz sand, the stirring member 12 will rotate continuously, which can not only make the added medicine mix more evenly, but also make the impurities suspended under stirring, which is more conducive to the separation of impurities. For the stirring member 12, having a plurality of through holes thereon is also more convenient for the flow of liquid to better remove impurities and purify the quartz sand.

[0028] Preferably, the stirring shaft is hollowly arranged so that the inside of the stirring shaft communicates with the accommodation space, and the medicine supplement member 15 is communicated to the inside of the stirring shaft; since it is necessary to add medicine into the accommodation space during the flotation process to combine with the impurities in the quartz sand, the medicine supplement member is communicated to the inside of the stirring shaft, and after the medicine is added, the medicine can quickly reach the bottom of the accommodation space to combine with the impurities in the quartz sand, making the cleaning more convenient.

[0029] As an implementation mode in the present application, the medicine supplement member 15 includes an infusion tube located above the accommodation space and a communication valve arranged at the infusion tube. The infusion tube includes a first infusion section communicated with the accommodation space and a second infusion section communicated with the first infusion section. The second infusion section is arranged to incline upward relative to the first infusion section, and the communication valve is arranged at the second infusion section; in the present application, the medicine supplement member 15 is communicated to the inside of the stirring shaft, and the stirring shaft is hollowly arranged, so the inside of the stirring shaft is also communicated with the accommodation space, that is, the medicine supplement member 15 is communicated with the accommodation space through the stirring shaft. Among them, the first infusion section is communicated with the accommodation space, that is, the first infusion section is the part connected to the stirring shaft, and the second infusion section is the part extending outward from the first infusion section, so as to facilitate the connection of the second infusion section to the outside. At the same time, for the second infusion section, it is arranged to incline upward relative to the first infusion section, so the second infusion section will be farther away from the horizontal plane, thus avoiding the collision between the scraper and the second infusion section when removing impurities through the scraper. At the same time, the communication valve is arranged at the second infusion section, so the second infusion section is arranged to incline upward, which is also more convenient for operating the communication valve, so as to realize the opening and closing of the second infusion section and the flow rate, and stably control the amount of water added during the flotation process.

[0030] In the present application, the scraper includes a rotating shaft 13 connected to the flotation machine 11 and a plurality of plate bodies 14 distributed circumferentially along the rotating shaft 13; since the scraper removes the floating impurities by rotation, by arranging a plurality of plate bodies 14 and the plate bodies 14 are distributed circumferentially along the rotating shaft 13, during the rotation of the rotating shaft 13, the plate bodies 14 can be continuously driven to rotate, so as to continuously remove the impurities, avoid the accumulation of impurities, and at the same time facilitate the impurities to be exposed above the horizontal plane in time, which is convenient for removing the impurities.

[0031] As a preferred embodiment in the present application, the accommodation space is filled with a flotation liquid. The plate body 14 has a scraping section immersed in the flotation liquid and a connecting section connecting the scraping section and the rotating shaft 13. The ratio of the length of the scraping section to the length of the connecting section is 1:3 to 1:5. The flotation liquid is a mixture of a reagent added to the accommodation space and water. The scraping section of the plate body 14 is the part immersed in the flotation liquid, which can carry out impurities. If the ratio of the length of the scraping section to the length of the connecting section is too large, that is, the length of the scraping section is too long, the immersed length of the scraping section increases, and the resistance during rotation will also increase. If the ratio of the length of the scraping section to the length of the connecting section is too small, that is, the length of the scraping section is too short, it is easy to incompletely clean the impurities.

[0032] In the present application, the flotation machine 11 includes a main body 111 forming an accommodation space and a cover body 112 disposed on the upper side of the main body 111. An opening communicating with the accommodation space is formed in the cover body 112, and the stirring member 12 is located at the side of the opening. Since the flotation machine 11 separates quartz sand from impurities, by providing the cover body 112 on the upper side of the main body 111, a certain blockage is formed for the accommodation space formed at the main body 111, thereby preventing foreign impurities from entering. At the same time, an opening is formed in the cover body 112, which can not only put the quartz sand in, but also ensure that the stirring member 12 can remove the impurities from the opening.

[0033] As a preferred embodiment in the present application, the cross-sectional shape of the main body 111 in the horizontal direction is a polygon. Since the cover body 112 is located on the upper side of the main body 111, the cross-sectional shape of the main body 111 in the horizontal direction is a polygon. Correspondingly, the cross-sectional shape of the cover body 112 in the horizontal direction is also a polygon, which is not only convenient for forming an opening in the cover body 112, but also the boundary between the opening and the adjacent part is more obvious, which is more convenient for the setting and installation of the stirring member 12.

[0034] In the present application, the pickling assembly includes a dehydration assembly 31 communicated with the first flotation assembly 1 and a deacidification assembly 32 communicated with the second flotation assembly 2. An acid leaching assembly 33 is further disposed between the dehydration assembly 31 and the deacidification assembly 32. Since the quartz sand received by the pickling assembly is transported from the first flotation assembly 1, the surface of the quartz sand will be relatively wet. By providing the dehydration assembly 31, the moisture attached to the first flotation assembly 1 can be removed during acid leaching, so as to facilitate subsequent processing. After acid leaching is completed, it is processed by the deacidification assembly 32, and then the quartz sand is transported to the second flotation assembly 2 for secondary flotation treatment.

[0035] The above are only embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the scope of the claims of the present application.
