Description

Technical Field

[0001] This utility model relates to the field of quartz sand treatment technology, specifically to a high-efficiency flotation and magnetic separation device for quartz sand. Background Technology

[0002] In the field of mineral processing, flotation technology, as an important mineral processing method, is widely used in the separation of various ores to effectively separate valuable minerals from gangue minerals, thereby improving ore grade and recovery rate. However, existing flotation equipment still faces many problems in practical applications, which seriously restrict the improvement of flotation effect and production efficiency.

[0003] Existing flotation equipment struggles to achieve uniform dispersion of raw materials after they enter the flotation machine. Raw materials often accumulate, preventing mineral particles from fully contacting subsequent processing stages. For example, when adding flotation reagents, uneven raw material dispersion hinders the reagents from acting evenly on each mineral particle. This results in ineffective alteration of the hydrophobicity of valuable mineral particles and the hydrophilicity of gangue mineral particles, consequently affecting the efficiency and quality of subsequent flotation separation. Furthermore, ores often contain a certain amount of magnetic impurities, which severely interfere with the flotation process. Existing flotation equipment typically uses only a single magnetic separator, which is insufficient for the complete removal of magnetic substances from the raw materials. Before the raw materials enter the agitation and subsequent processing stages, a single magnetic separator may only remove some obvious magnetic impurities, while some tiny or hidden magnetic substances are redispersed into the raw materials during agitation. These residual magnetic substances not only consume flotation reagents but also affect the adhesion of mineral particles to air bubbles, leading to a decline in flotation performance and compromised product quality. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a high-efficiency flotation and magnetic separation device for quartz sand, which solves the problems mentioned in the background art.

[0005] The solution to the above-mentioned technical problems provided by this utility model is as follows:

[0006] A high-efficiency flotation and magnetic separation device for quartz sand includes a flotation machine, the bottom of which is equipped with a support.

[0007] The flotation machine is equipped with a guide bucket at the bottom, and a feeding auger at the bottom of the guide bucket. The end of the feeding auger is connected to a second discharge guide pipe. A discharge hopper is installed at one end of the flotation machine. A comb roller, a stirring roller, a magnetic suspension roller, and a push roller are rotatably installed on the flotation machine. While the flotation machine is performing flotation, magnetic separation is also performed by the magnetic suspension roller.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the pusher roller is provided with a pusher plate, the stirring roller is provided with a paddle blade, and the comb roller is provided with comb teeth.

[0010] The beneficial effects of adopting the above-mentioned further solutions are:

[0011] The pusher plate design allows the pusher roller to more effectively push the raw material during rotation, dispersing it evenly within the flotation machine and preventing material accumulation. This provides favorable initial conditions for subsequent roller processing and flotation operations, ensuring that each mineral particle can fully contact the subsequent processing stages. The blades on the agitator roller, through powerful rotation, thoroughly mix the flotation reagents with the raw material, altering the surface properties of the mineral particles. This makes the surface of useful mineral particles hydrophobic and the surface of gangue mineral particles hydrophilic, creating favorable conditions for subsequent flotation separation. The comb teeth on the comb roller further break up any clumps that may form due to agitation, making the mineral particles more dispersed and uniform. This optimizes the dispersion state of the mineral particles, helping them to adhere more effectively to bubbles and improving the flotation separation effect.

[0012] Furthermore, there are two magnetic suspension rollers, which are located between the comb roller, the stirring roller and the push roller, respectively.

[0013] The beneficial effects of adopting the above-mentioned further solutions are:

[0014] Setting up two magnetic suspension rollers enables two-stage magnetic separation of magnetic substances in the raw material. The first magnetic suspension roller can initially remove most of the obvious magnetic impurities before the raw material enters the stirring and subsequent processing, reducing the interference of magnetic substances on the subsequent stirring and flotation processes. The second magnetic suspension roller can further adsorb residual magnetic substances that may have been redispersed in the raw material due to stirring after stirring, which greatly improves the magnetic separation effect, removes magnetic substances from the raw material as cleanly as possible, ensures the purity of the flotation process, reduces the consumption of flotation reagents by magnetic substances and their impact on flotation indicators, thereby improving the overall separation effect and product quality.

[0015] Furthermore, a drain pipe is provided on one side of the hopper, and a first discharge guide is installed on one side of the hopper. A discharge auger is rotatably installed inside the first discharge guide, and a drain plate is provided below the discharge auger in the first discharge guide.

[0016] The beneficial effects of adopting the above-mentioned further solutions are:

[0017] The drain pipe can discharge excess liquid carried in the floating material during the feeding process, achieving preliminary dehydration of the floating material, reducing its moisture content, and facilitating subsequent storage and transportation. The feeding auger in the first feeding conduit rotates to push the floating material forward, ensuring smooth feeding and avoiding blockages. The drain plate can further discharge the liquid remaining in the floating material during its movement, completing further solid-liquid separation, improving the dryness of the floating material, enhancing product quality, and facilitating further processing of the floating material.

[0018] Furthermore, the comb roller, stirring roller, magnetic suspension roller, and push roller are all arranged on a horizontal plane, and the comb roller, stirring roller, magnetic suspension roller, and push roller are driven by a power mechanism, which includes a motor and a reducer.

[0019] The beneficial effects of adopting the above-mentioned further solutions are:

[0020] Arranging the rollers on a horizontal plane ensures a smoother flow path for the raw materials within the flotation machine, reducing resistance and improving processing efficiency. It also facilitates installation and maintenance. Each roller is driven independently by a power mechanism (including a motor and a reducer), allowing for independent speed adjustment based on individual roller requirements. This ensures each roller operates at its optimal state, maximizing its functionality. For example, push rollers may require lower speeds for uniform agitation, while stirring rollers may need higher speeds to ensure thorough mixing of reagents and raw materials. Independent drive allows for precise control of each roller's speed, enhancing overall equipment performance and processing efficiency.

[0021] Furthermore, a feeding auger is also provided inside the second feeding conduit. Heavier raw materials in the flotation machine are guided into the feeding auger through the guide bucket and fed through the second feeding conduit connected to the feeding auger.

[0022] The beneficial effects of adopting the above-mentioned further solutions are:

[0023] The feeding auger inside the second feeding duct can propel heavier raw materials (gangue mineral particles) to ensure they can pass smoothly through the auger and avoid material accumulation and blockage. The guide bucket can accurately guide the heavy material sinking in the flotation machine into the feeding auger, making the transport of heavy material more orderly and improving the stability and reliability of the feeding. This feeding method can efficiently complete the feeding operation of heavy material, making the entire production process smoother, improving production efficiency, and also facilitating the subsequent processing and collection of heavy material.

[0024] This invention provides a high-efficiency flotation and magnetic separation device for quartz sand. It has the following beneficial effects:

[0025] This equipment integrates flotation and magnetic separation functions into a single flotation machine. During operation, the pusher roller, magnetic suspension roller, stirring roller, magnetic suspension roller, and combing roller work simultaneously. After the raw material enters the flotation machine, it undergoes sequential pushing and dispersion, magnetic separation, stirring and mixing, secondary magnetic separation, and combing without needing to be transferred between different devices, followed by direct flotation separation. This integrated design significantly shortens the process flow, reduces material transportation time and energy consumption between devices, and substantially improves overall production efficiency.

[0026] The pusher rollers push and initially disperse the raw materials, ensuring their uniform distribution within the flotation machine and creating favorable conditions for subsequent processing. The magnetic suspension rollers, through their rotating magnetic field, attract magnetic substances, achieving two-stage magnetic separation and effectively removing magnetic impurities from the raw materials. The agitator rollers' blades powerfully stir the mixture, thoroughly mixing the flotation reagents with the raw materials and altering the surface properties of the mineral particles, laying the foundation for flotation separation. The comb rollers' teeth further break up clumps, optimizing the dispersion of mineral particles and ensuring that useful mineral particles adhere more effectively to the bubbles. These rollers work in concert, processing the raw materials from different angles and optimizing the overall processing effect.

[0027] Because this equipment enables continuous processing of raw materials within the unit, it reduces the number of times materials are transferred between different devices, thereby minimizing material loss during transfer. Simultaneously, the synergistic effect of multiple rollers allows for more thorough separation of valuable components from the quartz sand, improving resource utilization. For example, in the magnetic separation process, two magnetic separations can more thoroughly remove magnetic impurities, reducing the loss of valuable minerals; in the flotation process, the optimized processing effect can improve the recovery rate of valuable minerals.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Please see Figures 1 to 4 As shown, the embodiments provided by this utility model are as follows:

[0038] Example 1

[0039] A high-efficiency flotation and magnetic separation device for quartz sand includes a flotation machine 3, a support 4 installed at the bottom of the flotation machine 3, a guide bucket 310 at the lower part of the flotation machine 3, a feeding auger 306 at the bottom of the guide bucket 310, a second discharge guide pipe 2 connected to the end of the feeding auger 306, a discharge hopper 1 installed at one end of the flotation machine 3, and a comb roller 301, an agitator roller 302, a magnetic suspension roller 303 and a pusher roller 304 rotatably mounted on the flotation machine 3. While the flotation machine 3 is performing flotation, magnetic separation is performed through the magnetic suspension roller 303.

[0040] Example 2

[0041] To further optimize the raw material processing flow within the flotation machine, improve mineral separation efficiency and equipment operating efficiency, for example, such as Figures 1 to 4As shown, this utility model also includes: a pusher plate 307 on the pusher roller 304, a paddle 308 on the stirring roller 302, and comb teeth 309 on the comb roller 301. The design of the pusher plate 307 enables the pusher roller 304 to more effectively push the raw material when rotating, dispersing the raw material evenly within the flotation machine 3, avoiding raw material accumulation, and providing good initial conditions for subsequent roller processing and flotation operations, ensuring that each mineral particle can fully contact the subsequent processing steps; the paddle 308 on the stirring roller 302, through strong rotation, can fully mix the flotation reagent with the raw material, changing the surface properties of the mineral particles, making the surface of the useful mineral particles hydrophobic and the surface of the gangue mineral particles hydrophilic, creating favorable conditions for subsequent flotation separation; the comb teeth 309 on the comb roller 301 can further break up any clumps that may be formed due to stirring, making the mineral particles more dispersed and uniform, optimizing the dispersion state of the mineral particles, helping the useful mineral particles to adhere more effectively to the bubbles, and improving the flotation separation effect. Two magnetic suspension rollers 303 are provided, and the two magnetic suspension rollers 303 are respectively located between the comb roller 301, the stirring roller 302, and the push roller 304. The two magnetic suspension rollers 303 enable two-stage magnetic separation of magnetic substances in the raw material. The first magnetic suspension roller 303 can initially remove most of the obvious magnetic impurities before the raw material enters the stirring and subsequent processing, reducing the interference of magnetic substances on the subsequent stirring and flotation processes. The second magnetic suspension roller 303 can further adsorb residual magnetic substances that may have been redispersed in the raw material due to stirring after stirring, greatly improving the magnetic separation effect, removing as much magnetic substance as possible from the raw material, ensuring the purity of the flotation process, reducing the consumption of flotation reagents by magnetic substances and their impact on flotation indicators, thereby improving the overall separation effect and product quality. The comb roller 301, stirring roller 302, magnetic suspension roller 303, and push roller 304 are also included. All four rollers (301, 302, 303, 304, and 305) are arranged on a horizontal plane. The comb roller, agitator roller, magnetic levitation roller, and pusher roller are each driven by a power mechanism 305, which includes a motor and a reducer. This arrangement of rollers on a horizontal plane ensures a smoother flow path for the raw material within the flotation machine 3, reducing material resistance and improving processing efficiency. It also facilitates installation and maintenance. Each roller is driven independently by the power mechanism 305 (including the motor and reducer), allowing for independent speed adjustment based on the working requirements of each roller. This ensures optimal operation and maximizes the functionality of each roller. For example, the pusher roller 304 may require a lower speed for uniform pushing, while the agitator roller 302 may require a higher speed to ensure thorough mixing of the reagent and raw material. Independent driving allows for precise control of the roller speed, improving the overall performance and processing effect of the equipment.

[0042] Example 3

[0043] To ensure smooth material feeding within the flotation machine, improve feeding efficiency and product quality, and facilitate subsequent storage, transportation, and further processing, for example, such as... Figures 1 to 4 As shown, this utility model also includes: a drain pipe 101 on one side of the hopper 1, a first discharge conduit 104 installed on one side of the hopper 1, a discharge auger 102 rotatably installed inside the first discharge conduit 104, and a drain plate 103 located below the discharge auger 102 in the first discharge conduit 104. The drain pipe 101 can discharge excess liquid carried in the floating material during the discharge process, achieving preliminary dehydration of the floating material, reducing the moisture content in the floating material, and facilitating subsequent storage and transportation; the discharge auger 102 inside the first discharge conduit 104 pushes the floating material forward by rotation, ensuring that the floating material can be discharged smoothly and avoiding blockage; the drain plate 103 can further discharge the liquid remaining in the floating material during the movement, completing further solid-liquid separation of the floating material, improving the dryness of the floating material, improving product quality, and also facilitating subsequent processing. For further processing of the floating material, a feeding auger 102 is also installed in the second feeding conduit 2. The heavier raw materials in the flotation machine 3 are guided into the feeding auger 306 through the guide bucket 310, and then fed through the second feeding conduit 2 connected to the feeding auger 306. The feeding auger 102 in the second feeding conduit 2 can push the heavier raw materials (gangue mineral particles) to ensure that they can pass through the second feeding conduit 2 smoothly and avoid material accumulation and blockage in the conduit. The guide bucket 310 can accurately guide the heavy material sinking in the flotation machine 3 into the feeding auger 306, making the conveying of heavy material more orderly and improving the stability and reliability of the feeding. This feeding method can efficiently complete the feeding operation of heavy material, making the entire production process smoother, improving production efficiency, and also facilitating the subsequent processing and collection of heavy material.

[0044] Working principle:

[0045] The raw material is directly fed into flotation machine 3, and flotation operation begins. Gas is introduced into flotation machine 3, creating a large number of fine, uniform bubbles. Because the surface of the valuable mineral particles is hydrophobic after treatment with flotation reagents, they quickly and selectively adhere to the bubbles. As the bubbles rise, the valuable mineral particles also rise to the surface, forming a layer of foam, i.e., the floating material. Gangue mineral particles, due to their hydrophilic surface, do not adhere to the bubbles and gradually sink to the bottom of flotation machine 3.

[0046] During flotation, the raw material first comes into contact with the pusher roller 304. Driven by the power mechanism 305, the pusher roller 304 rotates, and the pusher plate 307 on it continuously pushes the raw material forward while simultaneously dispersing it initially. This process breaks up any potential agglomeration of the raw material, ensuring that it is evenly distributed within the flotation machine 3. This provides favorable initial conditions for subsequent roller processing, as well as flotation and magnetic separation operations, ensuring that each mineral particle can fully contact the subsequent processing steps.

[0047] The raw material, propelled by the pusher roller 304, arrives at the first magnetic suspension roller 303. Driven by the power mechanism 305, the magnetic suspension roller 303 rotates at high speed, generating a magnetic field that strongly attracts magnetic substances in the raw material. The magnetic substances are rapidly adsorbed onto the surface of the magnetic suspension roller 303, initially separating from the non-magnetic substances in the raw material. This step effectively removes most of the obvious magnetic impurities from the raw material, reduces the interference of magnetic substances on subsequent flotation processes, and improves the accuracy of flotation separation.

[0048] After the initial magnetic separation, the raw material enters the stirring roller 302 area. The impellers 308 on the stirring roller 302 rotate rapidly under the drive of the power mechanism 305, providing powerful agitation to the raw material. During this agitation, the pre-added flotation reagents are thoroughly mixed with the raw material. The flotation reagents alter the surface properties of mineral particles, making the surfaces of useful mineral particles hydrophobic and gangue mineral particles hydrophilic. This difference in surface properties is crucial for subsequent flotation separation; the agitation operation ensures that the reagents uniformly cover the surface of each mineral particle, creating favorable conditions for flotation.

[0049] The stirred raw material then proceeds to the second magnetic roller 303. Since the stirring process may cause some loosely adsorbed magnetic substances to redisperse into the raw material, the second magnetic separation operation further adsorbs these residual magnetic substances. Through two magnetic separations, the separation effect is greatly improved, removing as much magnetic material as possible from the raw material, ensuring the purity of the flotation process, and reducing the consumption of flotation reagents and the impact of magnetic substances on flotation parameters.

[0050] Finally, the raw material reaches the comb roller 301 area. During rotation, the comb teeth 309 on the comb roller 301 meticulously comb the raw material, further breaking up any clumps that may have formed due to agitation, resulting in more dispersed and uniform mineral particles. Simultaneously, after being processed by the push roller 304, magnetic suspension roller 303, and stirring roller 302, the surface properties of the mineral particles have undergone significant changes. The combing action of the comb roller 301 helps to further optimize the dispersion state of the mineral particles, preparing them adequately for subsequent flotation separation and ensuring that useful mineral particles can more effectively adhere to the bubbles.

[0051] After the float rises to the surface, it enters the discharge hopper 1. The drain pipe 101 on one side of the discharge hopper 1 discharges excess liquid carried in the float, achieving initial dewatering. Subsequently, the float enters the first discharge conduit 104, moving forward under the propulsion of the internal discharge auger 102. The drain plate 103 below the first discharge conduit 104 further discharges the residual liquid in the float, completing solid-liquid separation and ultimately discharging the float. The heavy material (gangue mineral particles) sinking inside the flotation machine 3 enters the lower guide hopper 310 and, propelled by the feeding auger 306, is discharged through the second discharge conduit 2, which is connected to the feeding auger 306.
