Description

Technical Field

[0001] This application relates to the field of mineral processing engineering technology, and in particular to a flotation distributor and a flotation machine. Background Technology

[0002] In the field of mineral flotation, flotation distributors are a commonly used flotation device. The flotation distributor injects fluid into the flotation machine. The fluid contains many tiny bubbles, which adhere to the surface of mineral particles to form froth, creating a flotation effect. The part that floats to the top of the tank forms scum and leaves the liquid surface, while the non-floating minerals are carried to the bottom to form bottom scum.

[0003] Traditional flotation distributors typically spray air bubbles and water vertically upwards. A drawback is the relatively simple trajectory of the bubbles and mineral particles within the fluid. Due to the Coanda effect, the fluid deviates from its original flow direction, influencing each other and affecting flotation efficiency, often resulting in insufficient contact between minerals and bubbles. Furthermore, vertically sprayed flotation distributors cause significant radial differences in the contact effect between minerals and bubbles, leading to uneven flow and uneven bubble distribution, further impacting flotation performance. These problems result in low mineral flotation efficiency, wasted resources, and negatively affect the efficiency and quality of mineral processing. Therefore, there is a need for a simple, easy-to-implement, and highly effective flotation distributor technology to improve mineral flotation efficiency, reduce resource waste, and adapt to different environments and needs, providing a more reliable and efficient solution for mineral processing.

[0014] The multiple nozzles are arranged in a ring, and the base is ring-shaped.

[0015] In one feasible implementation, the tilt angle of the nozzle is determined based on the maximum orifice diameter of the nozzle and the number of nozzles.

[0016] In one feasible implementation, the plurality of nozzles within each nozzle are arranged in two or more rows, with the space at the nozzle outlets of the plurality of nozzles in each row increasing along a first direction, and the tilt angle of the nozzles being determined by the following formula:

[0017] H / L=(SH) / (n-1)d (1)

[0018] H 2 +L 2 =S 2 (2)

[0019] α=arctan (H / L) (3)

[0020] Where H represents the vertical height of the nozzle, L represents the projected length of the nozzle in the horizontal direction, S represents the length of the nozzle tube, n is the number of rows of multiple nozzle tubes in a single nozzle, d is the maximum orifice diameter of the nozzle tube, and α is the tilt angle of the nozzle, where α is defined as the angle between the nozzle axis and the horizontal direction.

[0023] In one possible implementation, the nozzle is detachably connected to the base, and a seal is provided between the nozzle and the base.

[0024] A flotation machine is provided according to a second aspect of the embodiments of this application, comprising:

[0025] As described in any of the above technical solutions, a flotation distributor;

[0026] A flotation machine housing, wherein the flotation distributor is connected to the bottom of the flotation machine housing;

[0027] A bubble generator connected to the flotation distributor.

[0029] The driving component, wherein the base of the flotation distributor is rotatably connected to the flotation machine housing;

[0030] An air distribution ring is provided, an air intake channel is formed on the base, the air intake channel leads to a plurality of nozzles, the air distribution ring is sleeved on the base, and the driving member is used to drive the base to rotate relative to the flotation machine housing and the air distribution ring.

The width of the base can be arranged horizontally, and the height of the base can be arranged vertically. The multiple nozzles are inclined relative to both the height and width of the base, meaning that the nozzles are inclined in both the horizontal and vertical directions. Therefore, when bubbles are output through the nozzles, the bubbles can travel along the inclined direction. The output of the nozzle makes the jet of bubbles more uniform, and for target minerals that fall without attached bubbles, they will be blown up multiple times by the bubbles output from the nozzle, increasing the chance of interaction between bubbles and mineral particles, thereby improving flotation efficiency and mineral recovery rate. Furthermore, since the inclined nozzle can form a stable rotating flow field in the flotation machine, the surface wettability of the minerals is higher, thereby reducing fluid waste, reducing the total amount of fluid required in the flotation process, and reducing the energy consumption of the flotation process. Furthermore, the inclined nozzle is conducive to forming a rotating flow field. Due to the centrifugal force, heavier tailings will gather towards the center of the flow field, which is conducive to tailings discharge. Attached Figure Description

[0049] To better understand the above technical solutions, the technical solutions of the embodiments of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this application and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this application, rather than limitations on the technical solutions of this application. In the absence of conflict, the embodiments of this application and the technical features in the embodiments can be combined with each other.

[0050] like Figures 1 to 4 As shown, a flotation distributor 100 is provided according to a first aspect of the present application, comprising: a base 110; a plurality of nozzles 120, one end of the plurality of nozzles 120 being connected to the base 110, and the plurality of nozzles 120 being inclined relative to the base 110 in both height and width directions.

[0051] The flotation distributor 100 provided in this embodiment includes a base 110 and a plurality of nozzles 120. One end of each nozzle 120 is connected to the base 110. The nozzles 120 are inclined relative to the base 110 in both height and width directions. In use, the flotation distributor 100 serves as a component of a flotation machine. The base 110 of the flotation distributor is disposed within the flotation machine. The width of the base 110 can be arranged horizontally, and its height can be arranged vertically. The multiple nozzles 120 are inclined relative to the base 110 in both height and width directions, thus ensuring that each nozzle 120 is inclined relative to both the horizontal and vertical directions. Based on this, when the nozzles 120... When the nozzle 120 outputs bubbles, the bubbles can be output along the inclined direction, which makes the bubble jet more uniform. For target minerals that fall without attached bubbles, they will be blown up multiple times by the bubbles output from the nozzle 120, increasing the interaction opportunities between bubbles and mineral particles, thereby improving flotation efficiency and mineral recovery rate. Furthermore, since the inclined nozzle 120 can form a stable rotating flow field in the flotation machine, the surface wettability of the minerals is higher, thereby reducing fluid waste and reducing the total amount of fluid required in the flotation process, thus reducing the energy consumption of the flotation process. Furthermore, the inclined nozzle 120 is conducive to forming a rotating flow field. Due to the centrifugal force, heavier tailings will gather towards the center of the flow field, which is conducive to tailings discharge.

[0052] like Figures 1 to 4 As shown, in one feasible embodiment, the nozzle 120 includes: a housing 121 and a plurality of nozzles 122 disposed within the housing 121, wherein the plurality of nozzles 122 are inclined relative to the base 110 in both the height and width directions.

[0053] In this technical solution, a nozzle 120 is further provided. Each nozzle 120 may include a housing 121 and a nozzle pipe 122 disposed in the housing 121. Based on this, the airflow can be output through the nozzle pipe 122. The setting of the nozzle pipe 122 facilitates the inclined arrangement of the nozzle 120. On the other hand, the setting of the nozzle pipe 122 facilitates the control of the airflow velocity, which can increase the contact opportunity between the bubbles and the minerals, thereby improving the recovery rate.

[0054] like Figure 2 As shown, in one feasible embodiment, a plurality of nozzles 120 share a first housing 1211, and each nozzle 122 is inclinedly disposed within the first housing 1211.

[0055] In this technical solution, a method of setting multiple nozzles 120 is further provided. Multiple nozzles 120 can share a housing 121, that is, all nozzles 122 are arranged in a housing 121. Multiple nozzles 122 can be divided into multiple groups to form multiple nozzles 120. This setting can improve the mechanical strength and operational stability of the flotation distributor 100, thereby improving the service life of the flotation distributor 100.

[0056] like Figure 3 As shown, in one possible embodiment, each nozzle 120 has a nozzle 122 equipped with a second housing 1212, which is inclined relative to the base 110 in both height and width directions.

[0057] In this technical solution, another arrangement of the nozzles 120 is provided. Each nozzle 120 can be equipped with a second housing 1212. That is, each second housing 1212 is provided with multiple nozzles 122. The multiple second housings 1212 are arranged at intervals, so that the nozzles 120 are connected to the base 110. At the same time, the nozzles 120 are arranged at an angle. Based on this, during the use of the flotation distributor 100, the angled nozzles 120 can form a stable rotating flow field. Due to the centrifugal force, the heavier tailings will gather towards the center of the flow field. This part of the tailings can be transported through the gap between two adjacent second housings 1212, which facilitates the discharge of tailings.

[0058] like Figure 1 , Figure 3 and Figure 5 As shown, in some examples, to facilitate the processing of the second shell 1212 and to avoid the second shell 1212 from obstructing the discharge of tailings, the second shell 1212 can be in block shape.

[0059] like Figure 1 and Figure 2As shown, in one feasible embodiment, a plurality of nozzles 120 are arranged in a ring, and the base 110 is ring-shaped.

[0060] This technical solution further provides an arrangement of multiple nozzles 120 and a base 110. The multiple nozzles 120 are arranged in a ring, and the inclined nozzles 120 facilitate the formation of a rotating flow field. Due to centrifugal force, heavier tailings will accumulate towards the center of the flow field and be discharged through the central ring of the nozzle 120 device. Other tailings can also fall through the gaps between the nozzles 120. This effectively reduces tailings congestion and facilitates stable and continuous operation of the equipment.

[0061] In one feasible implementation, the tilt angle of the nozzle 120 is determined based on the maximum orifice diameter of the nozzle 122 and the number of nozzles 120.

[0062] In this technical solution, a method for determining the tilt angle of the nozzle 120 is further provided. With such a setting, at least the tilt angle of the nozzle 120 is related to the maximum orifice diameter of the nozzle 122 and the number of nozzles 120, ensuring that enough bubbles can be produced to contact the minerals, while facilitating the formation of a stable swirling field.

[0063] like Figure 1 and Figure 2 As shown, in one feasible embodiment, the plurality of nozzles 122 within each nozzle 120 are arranged in two or more rows, the space of the nozzle outlet 1221 of the plurality of nozzles 122 in each row increases along a first direction, and the nozzle inlet 1222 is connected to the base 110.

[0064] In this technical solution, a further arrangement of multiple nozzles 122 within each nozzle 120 is provided. Each nozzle 120 includes multiple nozzles 122, which are arranged in a row. Each nozzle 122 includes a nozzle hole, so that each row includes multiple nozzle holes. The radius of the multiple nozzle holes in each row increases sequentially to increase the flow rate, increase the kinetic energy of the fluid, and make the fluid sprayed more evenly onto the mineral surface.

[0065] In one feasible implementation, the tilt angle of the nozzle 120 is determined by the following formula:

[0066] H / L=(SH) / (n-1)d (1)

[0067] H 2 +L 2 =S 2 (2)

[0068] α=arctan (H / L) (3)

[0069] like Figure 3As shown, H represents the vertical height of nozzle 120, L represents the projected length of nozzle 120 in the horizontal direction, S represents the length of nozzle 122, n is the number of rows of nozzles 122 within a single nozzle 120, d is the maximum orifice diameter of nozzle 122, and α is the tilt angle of nozzle 120, where α is defined as the angle between the axis of nozzle 120 and the horizontal direction.

[0070] This technical solution further provides a design method for the tilt angle of the nozzle 120. This setting facilitates the quantification of the design angle of the nozzle 120, enabling the flow emitted through the nozzle 120 to be sprayed more evenly onto the mineral surface, and increasing the opportunity for interaction between the mineral and the air bubbles.

[0071] In one feasible implementation, the orifice diameter of the nozzle 122 gradually increases from the input end to the output end. This arrangement allows for a more uniform flow rate of bubbles output through the nozzle 122.

[0072] In one feasible implementation, the orifice diameter of the nozzle 122 gradually decreases from the input end to the output end. This configuration allows for a faster flow rate of bubbles output through the nozzle 122.

[0073] In one possible implementation, the nozzle 120 is detachably connected to the base 110, and a seal is provided between the nozzle 120 and the base 110.

[0074] The nozzle 120 is detachably connected to the base 110, making the maintenance of the flotation distributor 100 more convenient. A seal is provided between the nozzle 120 and the base 110 to reduce the probability of impurities entering between the base 110 and the nozzle 120, ensuring the reliability of the flotation distributor 100.

[0075] In some examples, in order to overcome the problem that the flotation process is prone to uneven contact between minerals and bubbles, resulting in few contact opportunities and poor flotation effect, this application provides a flotation distributor 100 that generates a rotating upward flow field.

[0076] The flotation distributor 100, through modifications to the tilt direction and structural design of the nozzles 120, ensures that the nozzles 120 are tilted relative to the base 110 in both height and width. This results in a more uniform jet flow, and for target minerals without attached bubbles, the nozzles 120 repeatedly agitate them, increasing the interaction between bubbles and mineral particles, thereby improving flotation efficiency and mineral recovery. The flotation distributor 100 consists of multiple nozzles 120 and a base 110. When applied within a flotation machine, the nozzles 120 spray upwards at an angle, and the number of nozzles 120 is evenly distributed. The bottom of each nozzle 120 is connected to the base 110, which secures and supports the nozzles 120. The design of the nozzles 120 includes the tilt angle of the nozzle groups, the number of nozzle groups, and their distribution.

[0077] The nozzle tilt angle of 120° is calculated using the following formula:

[0078] H / L=(SH) / (n-1)d (1)

[0079] H 2 +L 2 =S 2 (2)

[0080] α=arctan (H / L) (3)

[0081] like Figure 3 As shown, H represents the vertical height of nozzle 120, L represents the projected length of nozzle 120 in the horizontal direction, S represents the length of nozzle 122, n is the number of rows of nozzles 122 within a single nozzle 120, d is the maximum orifice diameter of nozzle 122, and α is the tilt angle of nozzle 120, where α is defined as the angle between the axis of nozzle 120 and the horizontal direction.

[0082] In some examples, by substituting S = 50 mm and d = 5 mm into the above equation set (1)(2)(3), the H, L, and α parameters of the nozzle 120 group under different nozzle 120 row numbers n in Table 1 can be obtained.

[0083] Table 1. Partial Design Parameters of Nozzle 120

[0084]

[0085] In this embodiment, the mineral particles are given 3 flotation opportunities (n=3). According to formulas (1)(2)(3), the vertical height H of nozzle 120 is calculated to be 38.1765mm, the horizontal distance L from the outlet to the inlet of nozzle 120 is 32.2886mm, and the tilt angle α of nozzle 120 group is 49.78°.

[0086] The flotation distributor device uses a circular base 110. The lower base 110 has an outer diameter of 180 mm, an inner diameter of 80 mm, and a height of 20 mm, providing structural support and fluid injection for the upper nozzles 120. Sixteen inclined block nozzles 120 are evenly arranged on the base 110. Each block nozzle 120 has 36 nozzle tubes 122, for a total of 576 nozzle tubes 122. Within each nozzle 120, the nozzle tubes 122 are divided into three rows, with 12 nozzle holes per row. The smallest nozzle hole diameter is 2 mm, and the largest is 4.74 mm. They are cylindrical in design, all with a length of 50 mm, and the radius increases sequentially to increase the flow rate and kinetic energy of the fluid, allowing the fluid to be sprayed more evenly onto the mineral surface.

[0087] The flotation machine has a slurry poured in at the top and flotated minerals discharged at the bottom, while bottom slag is discharged at the bottom. The slurry is poured into the flotation machine, and then a gas-water mixture is fed into the base 110. As the gas-water mixture enters from the bottom of the nozzle 120, it is compressed and accelerated, entering the nozzle 120 and being ejected through the cylindrical nozzle outlet, carrying a large number of fine air bubbles. These bubbles, upon entering the slurry, interact with the mineral particles, forming a gas-liquid interface on their surface. This interface has high affinity and surface tension. As the bubbles rise to the surface, they carry the mineral particles attached to their surface, thus achieving mineral separation and recovery.

[0088] The tilt angle and structural design of nozzle 120 create a rotating flow field, generating a large tangential velocity during the contact between the air-water mixture and the slurry. This creates circulation, increasing the contact time and intensity between the minerals and the fluid. Target minerals that fall without attached air bubbles will be repeatedly blown up by nozzle 120. During this process, the target minerals are continuously blown away from the bottom of the flotation machine and floated to the surface. At this point, because the unwanted impurities are heavier, they tend to move towards the center of the flow field due to inertia and sink, exiting the flotation machine through the middle of the flotation distributor. The lighter target minerals move outwards and float to the top of the flotation machine. Simultaneously, the stable flow field facilitates the discharge of tailings and prevents clogging near nozzle 120.

[0089] In specific implementations, the tilt angle of the nozzle 120 can be adjusted according to the mineral type and processing requirements. Furthermore, the geometry of the nozzle 120 can also be designed according to actual needs. For example, in specific implementations, the nozzle 120 can adopt a scaling structure. In addition, multiple nozzles 120 can be combined as needed to make the flow field more uniform. Specifically, multiple nozzles 120 can be arranged according to the required flotation processing capacity and equipment space, and connected to the same fluid pipeline.

[0090] In summary, the flotation distributor 100 device with a rotating upward flow field provided by the present invention has been optimized and innovated in many aspects such as tilt angle, nozzle distribution and number, and geometric structure design. It can effectively improve mineral flotation efficiency, reduce production costs, and has broad application prospects.

[0091] In some examples, the base 110 and nozzles 120 of the flotation distributor 100 are made of wear-resistant and corrosion-resistant materials. The nozzles 120 use a ring-shaped base 110, the size of which is designed according to the size of the flotation machine. The base 110 provides structural support and fluid injection for the nozzles 120 above. Multiple inclined block-shaped nozzles can be evenly arranged on the base 110, with each block-shaped nozzle 120 having multiple small nozzles. Within each nozzle 120, there are several rows, each row including multiple nozzles, using a cylindrical design. The radii of the multiple nozzles in each row increase sequentially to increase the flow rate, increase the kinetic energy of the fluid, and make the fluid more evenly sprayed onto the mineral surface.

[0092] Furthermore, the components of nozzle 120 need to be designed to achieve optimal flotation results, specifically including the following:

[0093] 1. The tilt angle of nozzle 120 can be designed and adjusted according to different application scenarios. The tilt angle of nozzle 120 is reasonably calculated according to requirements and can be selected based on factors such as the properties of the fluid, the characteristics of the flotation material, and the throughput.

[0094] 2. The optimized nozzle 120 structure features a block design for each nozzle 120. The number of rows of nozzles 122 within each nozzle 120 can be adjusted according to the specific flotation production process requirements to meet different production needs. The number of rows of nozzles 120 can be single or multiple, with multiple nozzle holes distributed in each row. The nozzles are cylindrical with progressively increasing nozzle radii to increase flow rate and ensure more uniform fluid distribution onto the mineral surface, thereby increasing the interaction opportunities between the minerals and air bubbles. Specifically, multiple nozzles 120 can be arranged according to the required flotation capacity and equipment space, and connected to the same base 110 fluid pipeline.

[0095] 3. The nozzle 120 can adopt a structure design such as a tapered nozzle 122 or a gradually expanding and contracting nozzle to form a finer jet flow field, thereby achieving a more efficient flotation effect. In addition, the nozzle 120 can adopt various shapes, such as circular, elliptical, and rectangular, to adapt to the needs of different mineral particle sizes and flotation machine structures.

[0096] 4. For ease of maintenance and replacement, the base 110 of the nozzle 120 can be detachable. Additionally, the nozzle 120 assembly can be designed as a replaceable modular structure for easy on-site maintenance and replacement.

[0097] 5. Furthermore, to further improve the service life and stability of the nozzle 120, a seal can be installed at the interface between the nozzle 120 and the base 110 to prevent fluid leakage and impurity entry. Additionally, a protective cover can be installed around the nozzle 120 to prevent damage from mineral particles or other impurities.

[0098] The flotation distributor 100 provided in this application embodiment has at least the following beneficial effects:

[0099] Improving flotation efficiency: The inclined nozzle 120 of the flotation distributor can improve the uniformity of fluid jetting, allowing minerals and fluids to come into more complete contact, increasing the contact opportunities between minerals and fluids. For target minerals that fall without attached bubbles, they will be blown up multiple times by the nozzle 120, increasing the interaction opportunities between bubbles and mineral particles. This makes the minerals easier to float, and the minerals can complete the flotation in a shorter time, reducing production costs and thus improving flotation efficiency and mineral recovery rate.

[0100] Reduced energy consumption: The inclined nozzle 120 creates a stable rotating flow field in the flotation machine, resulting in higher surface wettability of the minerals and reduced fluid waste. This reduces the total amount of fluid required during the flotation process, thus lowering energy consumption.

[0101] Reduced congestion: The inclined nozzle 120 facilitates the formation of a rotating flow field. Due to centrifugal force, heavier tailings will gather towards the center of the flow field and be discharged through the central ring of the nozzle 120 device. Other tailings can also fall through the gaps in the nozzle 120. This effectively reduces tailings congestion and promotes stable and continuous operation of the equipment.

[0102] In summary, the flotation distributor 100 device of this invention, which generates a rotating upward flow field, is technically innovative and practical, and has obvious application prospects and commercial value.

[0103] The embodiments of the present invention are described in detail below based on the technical solution provided by the present invention:

[0104] like Figures 5 to 7 As shown, a flotation machine is provided according to a second aspect of the embodiments of this application, comprising: a flotation distributor 100 as described in any of the above technical solutions; a flotation machine housing 210, wherein the flotation distributor 100 is connected to the bottom of the flotation machine housing 210; and a bubble generator 220, wherein the bubble generator 220 is connected to the flotation distributor 100.

[0105] The flotation machine provided in this application embodiment includes a flotation distributor 100 as described in any of the above technical solutions, and therefore the flotation machine has all the beneficial effects of the flotation distributor 100 of any of the above technical solutions.

[0106] In the flotation machine provided in this embodiment, during use, the bubble generator 220 is connected to the flotation distributor 100. The flotation distributor 100 outputs bubbles through the nozzle 120. The bubbles contact the slurry inside the flotation machine housing 210. Minerals in the slurry that are easily contacted with air are carried by the bubbles to the top of the flotation machine and eventually discharged from the flotation machine housing 210. Minerals in the slurry that are hydrophilic or not easily contacted with air are not captured by the bubbles and are eventually discharged from the bottom of the flotation machine housing 210. Based on this, the hydrophilic or hydrophobic properties of the minerals can be utilized.

[0107] During the operation of the flotation distributor 100, the air-water mixture flows from the lower annular base 110 into the upper nozzle 120, and then is ejected obliquely from the nozzle 120, forming a rotating flow field. The tilt angle of the nozzle 120 causes the ejected fluid to generate a large tangential velocity when it comes into contact with the minerals, which helps to blow up the falling minerals and keep them in contact with the air bubbles. In addition, the design of the nozzle 120 can also change the movement state of the air-water mixture in the slurry pool, making it form a circulation, thereby increasing the contact time and contact intensity between the minerals and the air-water mixture. At the same time, the stable flow field is conducive to the discharge of tailings and is less likely to clog near the nozzle 120.

[0108] During operation, the slurry is poured into the flotation machine from the top. As the air-water mixture contacts the slurry, the target minerals are continuously carried aloft, increasing the contact time between the minerals and the fluid. At this time, because the unwanted ejected impurities are denser, they tend to move towards the center of the flow field due to inertia and sink, while the lighter target minerals move to the surrounding areas. In this process, the target minerals are continuously blown away from the bottom of the slurry and floated to the surface. Compared to traditional flotation distributors, the inclined nozzle 120 design of the flotation distributor 100 in this embodiment can more effectively bring air bubbles into contact with the minerals, making it easier for the minerals to be blown aloft, thereby improving the flotation rate. Furthermore, due to the inclined nozzle 120 design, mineral particles can rotate and descend along the wall of the nozzle 120, forming different trajectories, thus achieving better separation.

[0109] like Figure 6 As shown, in one feasible embodiment, the flotation machine further includes: a drive member 230, the base 110 of the flotation distributor 100 is rotatably connected to the flotation machine housing 210; an air distribution ring 240, an air inlet channel is formed on the base 110, the air inlet channel leads to a plurality of nozzles 120, the air distribution ring 240 is sleeved on the base 110, and the drive member 230 is used to drive the base 110 to rotate relative to the flotation machine housing 210 and the air distribution ring 240.

[0110] In this technical solution, the flotation machine also includes a drive unit 230 and an air distribution ring 240. During use, the drive unit 230 can drive the flotation distributor 100 to rotate. Based on this, the movement trajectory of the bubbles output through the flotation distributor 100 is more complex, making the output mode of the bubbles more uniform, making it easier for the bubbles to contact the minerals, and making it easier to form a stable swirling field.

[0111] In this technical solution, the flotation machine may also include an air distribution ring 240, which is connected to the base 110. When the driving member 230 drives the base 110 to rotate, the base 110 rotates relative to the air distribution ring 240. The air distribution ring 240 can always supply mixed airflow to the flotation distributor 100, which facilitates the pipeline arrangement of the bubble generator 220.

[0112] like Figure 7 As shown, in one feasible embodiment, a guide rail 250 is formed on the flotation machine housing 210, the flotation distributor is connected to the flotation machine housing 210 through the guide rail 250, and the bubble generator 220 is connected to the flotation distributor through a telescopic tube.

[0113] In this technical solution, a guide rail 250 can be formed on the flotation machine housing 210 of the flotation machine. The flotation distributor is connected to the flotation machine housing 210 through the guide rail 250, and the bubble generator 220 is connected to the flotation distributor through a telescopic tube. Based on this, the position of the flotation distributor 100 can be adjusted through the guide rail 250. On the one hand, this facilitates the assembly of the flotation distributor 100; on the other hand, during use, the flotation distributor 100 can be moved through the guide rail 250. This setting can also make the bubble output method more complex and can also increase the contact probability between the bubbles and the minerals.

[0114] like Figure 7 As shown, in one feasible embodiment, the flotation machine further includes a plurality of guide plates 260, which are arranged in pairs on both sides of the flotation machine housing 210. One end of the guide plate 260 is hinged to the flotation machine housing 210, and the other end extends in the direction of the flotation distributor.

[0115] In this technical solution, the flotation machine may also include multiple guide plates 260. One end of the guide plate 260 is hinged to the inner wall of the flotation machine housing 210, and the other end extends toward the flotation distributor 100. Based on this, by adjusting the inclination angle of the guide plate 260, the divergence angle of the bubbles output through the flotation distributor 100 can be adjusted, which facilitates the control of the propagation speed of the bubbles in the flotation machine housing 210, and makes it easier to adapt the flotation machine to different types and requirements of minerals, thereby increasing the applicability of the flotation machine.

[0116] like Figure 7As shown, in some examples, the flotation machine may also include a telescopic rod 270, one end of which is connected to the flotation machine housing 210 and the other end of which is connected to the flotation distributor 100.
