Description

Technical Field

[0001] The present invention generally relates to the field of flotation, and more particularly to a flotation device capable of automatically adding reagents. Background Art

[0002] A flotation machine, short for a flotation separator, refers to the mechanical equipment used in the flotation process. In a flotation machine, the pulp treated with reagents is agitated and aerated, so that some of the mineral particles selectively adhere to the bubbles; the particles floating to the surface of the pulp are scraped out to form a foam product, and the rest remain in the pulp to achieve the purpose of separating minerals. There are many structural forms of flotation machines, including mechanically agitated type, aerated agitated type, and aerated type.

[0003] The flotation reagents of the flotation machine are added in two ways, including one-time dosing and sectional dosing. However, whether it is one-time dosing or sectional dosing, it is manually operated, which is not only time-consuming and laborious, but also difficult to evenly disperse the reagents by manual feeding method, affecting the reaction time in the initial stage. Summary of the Invention

[0004] In view of the problems existing in the above-mentioned prior art, the present invention provides a flotation device capable of automatically adding reagents. A flotation device capable of automatically adding reagents is characterized by comprising: a flotation cell and a reagent automatic adding device. The reagent automatic adding device includes a plurality of reagent leveling components arranged in the flotation cell and a reagent supply component located outside the flotation cell for supplying reagents to each reagent leveling component; the reagent leveling component includes an aggregate bowl, which is inverted at the bottom of the flotation cell; a connecting pipe, one end of which is connected to the bottom of the aggregate bowl and communicates with the inside of the aggregate bowl, and the other end of which is connected to the reagent supply component. With the above technical features, during the operation of the flotation machine, the staff can turn on the reagent supply component to supply reagents into the aggregate bowl. Since the supply bowl is in an inverted state and located at the bottom of the flotation cell, the bowl wall reduces the flow rate of the ore material inside the bowl, making the reagent more concentrated after falling, unable to disperse upward like above, and evenly settling downward. When leaving the bowl mouth, the flow rate of the ore material is relatively large, so that the reagent is evenly mixed in the surrounding ore material. Moreover, with the generation of foam, it drives the reagent to flow towards the inside of the aggregate bowl, making the reagent repeatedly mix in the area of the aggregate bowl. This method greatly reduces the uneven distribution of the overall reagent concentration caused by excessive local reagent concentration. Moreover, this method not only realizes the automatic addition of reagents, but also reduces the concentration of reagents through the slow descent principle and then integrates them into a large range of ore materials, thereby improving the uniformity of reagent mixing.

[0005] In some embodiments, a main supply pipe is provided at the inner bottom of the flotation cell, which is interconnected with the chemical supply assembly; the connecting pipe of each chemical equalizing assembly is interconnected and communicated with the main supply pipe. Thereby, unnecessary material waste is reduced, and installation, inspection, and maintenance are facilitated.

[0006] In some embodiments, the connecting pipe is rotationally and sealingly connected to the main supply pipe, and a power assembly for driving the aggregate bowl to rotate is provided at a position corresponding to each aggregate bowl on the main supply pipe. Thereby, as foam is generated in the flotation cell, since the opening of the aggregate bowl is inverted, foam will also accumulate in the aggregate bowl. Therefore, the rotation of the aggregate bowl driven by the power assembly can drive the ore or foam to flow towards the edge of the bowl opening under centrifugal force. While creating space inside the aggregate bowl, it also evenly distributes the chemical agent. Moreover, the force of the aggregate bowl acts downward, and after the chemical agent is distributed downward, it follows the foam and flows upward, increasing the flow pattern of the chemical agent and improving the mixing uniformity.

[0007] In some embodiments, the power assembly includes a driven gear ring coaxially fixed on the outer peripheral surface of the connecting pipe; a driving motor fixed on one side of the driving pipe, and the output shaft of the driving motor is parallel to the rotation axis of the connecting pipe; a driving gear coaxially fixed on the output shaft of the driving motor, and the driving gear meshes with the driven gear ring. Thereby, when the driving motor rotates, the rotation of the aggregate bowl is driven through the meshing of the driving gear and the driven gear ring. The driving structure is simple, facilitating subsequent installation and maintenance.

[0008] In some embodiments, the chemical supply assembly includes a chemical supply tank provided outside the flotation cell; a chemical supply pump interconnected with the chemical supply tank; a chemical supply pipe interconnected with the outlet of the chemical supply pump, and the other end of the chemical supply pipe is interconnected with the main supply pipe. Thereby, the staff can pre - mix and collect the solid chemical agent in the chemical supply tank to improve the reaction efficiency of the subsequent chemical agent, and then realize the automatic supply of the chemical agent by controlling the chemical supply pump.

[0009] In some embodiments, a plurality of guide vanes for guiding the liquid medicine to the bowl opening are provided on the inner wall of the aggregate bowl. Thereby, the guide vanes play a role in disturbing the flow, effectively guiding the ore in the aggregate bowl, driving the ore to flow towards the edge of the bowl opening along with the trend, and enabling the chemical agent to be fully mixed.

[0010] In some embodiments, a plurality of material equalizing openings are distributed at the edge of the aggregate bowl. Thereby, during the rotation of the aggregate bowl, the opening of the material equalizing openings is conducive to the exchange of ore inside and outside the aggregate bowl, improving the efficiency of chemical agent mixing and the range of dispersion.

[0011] In some embodiments, a lifting driving member for controlling the lifting of the main supply pipe is provided in the flotation cell. One end of the lifting driving member is fixed to the flotation cell and the other end is connected to the main supply pipe. Thus, during the rotation of the aggregate bowl, the disturbed range is a space with a fan-shaped cross-section. The staff can control the range of ore stirring by lifting the aggregate bowl, further improving the distribution efficiency of the reagent.

[0012] In some embodiments, an area sensor for monitoring the foam area at the port of the flotation cell is provided in the flotation cell. The area sensor is connected to the chemical feed pump and is fixed at the port of the flotation cell, and an infrared emission end and an infrared receiving end are integrated therein. Thus, after the flotation equipment is started, the liquid level of the flotation cell is monitored by the area sensor. When the foam on the surface of the flotation cell is lower than the preset value, the chemical feed pump is controlled to be intermittently turned on, so that the reagent enters the flotation cell and is fully mixed with the ore until the foam accumulates on the surface of the flotation cell; when the foam area on the surface of the flotation cell is greater than the preset value, the controller sends a stop signal to the chemical feed pump to stop the supply of the reagent in the flotation cell.

Other features of the present disclosure will become easily understood through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Next, the preferred embodiments (or implementation manners) of the present invention will be described in detail with reference to the accompanying drawings.

[0025] The present invention provides a flotation device capable of automatically adding medicine, which includes a flotation cell 1, a flotation column 13 erected in the central area of the flotation cell 1, a rotating shaft 15 coaxially arranged inside the flotation column 13, a rotor 17 fixed at the bottom of the rotating shaft 15, a first driving component 16 arranged at the upper end of the flotation shaft and used to drive the rotating shaft 15 to rotate, and an air inlet pipe 18 is also connected to the flotation column 13; a concentrate tank 19 is also arranged on one side edge of the flotation cell 1, and a scraping mechanism 2 for introducing the foam floating material into the concentrate tank 19 is arranged at the tank opening of the concentrate tank 19, and a medicine automatic adding device 3 for automatically adding medicine is also arranged inside the flotation cell.

[0026] Next, reference is made to Figures 1 - 7 to describe a flotation device capable of automatically adding medicine provided by an embodiment of the present invention.

[0027] Figure 1 The figure shows the schematic diagram of the overall structure of a flotation device capable of automatically adding medicine provided by an embodiment of the present invention, Figure 2 The figure shows the schematic diagram of the overall structure after series connection of a flotation device capable of automatically adding medicine provided by an embodiment of the present invention. Refer to Figure 1As shown in the figure, a flotation device capable of automatically adding chemicals provided in this embodiment includes a flotation cell 1. The flotation cell 1 is a tank body with an open top. Generally, the flotation cell 1 is a standard rectangular structure so that the flotation devices can be arranged side by side in series. A feed inlet 11 for ore material to flow in is provided in the middle of one side of the flotation cell 1, and a discharge outlet 12 for discharging waste is provided on the side of the flotation cell 1 opposite to the feed inlet 11. Refer to Figure 2 As shown in the figure, when multiple flotation devices are connected in series, the discharge outlet 12 of one flotation device corresponds to the feed inlet 11 of the adjacent flotation device, enabling the ore material to undergo multiple rounds of flotation in sequence, improving the flotation efficiency and reducing unnecessary waste. An alternative port 5 is also provided at the bottom of one side of the flotation cell 1, enabling the flotation device to perform either direct flotation or reverse flotation.

[0028] Figure 3 The figure shows a cross-sectional view of the internal structure of a flotation device capable of automatically adding chemicals provided in an embodiment of the present invention. Refer to Figure 3 As shown in the figure, a flotation column 13 is vertically provided in the middle of the mouth of the flotation cell 1. The flotation column 13 is fixedly connected to the flotation cell 1 through a support frame 14. The middle of the flotation column 13 is a hollow structure, and a rotating shaft 15 is coaxially arranged inside it. There is a gap between the rotating shaft 15 and the flotation column 13, and the rotating shaft 15 is rotatably connected to the flotation column 13. A first driving component 16 fixedly connected to the support frame 14 is provided at the top of the rotating shaft 15. Generally, the first driving component 16 is a driving member composed of a driving motor, a belt, and a driving wheel, or it can also be a driving member composed of a driving motor and multiple transmission gears. The main purpose is to drive the rotating shaft 15 to rotate. A rotor 17 is coaxially and fixedly connected to the lower end of the rotating shaft 15, and an air inlet pipe 18 is also provided on the circumferential surface of the flotation column 13. One end of the air inlet pipe 18 is connected and communicated with the flotation column 13, and the other end of the air inlet pipe 18 extends upward and is located above the ore material liquid level. When the flotation device is working, the first driving component 16 drives the rotating shaft 15 to rotate, causing the rotor 17 to rotate at a high speed. The rotation of the rotor 17 generates negative pressure at the bottom of the flotation cell 1, driving air to enter the bottom of the flotation column 13 through the air inlet pipe 18 and generating a large number of bubbles with the rotation. With the addition of chemicals, the required minerals in the ore material will adhere to the bubbles and float on the ore material along with the bubbles. On the side of the flotation cell 1, a concentrate tank 19 is also provided, and a scraping mechanism 2 for pushing the frothy ore material into the concentrate tank 19 is provided above the concentrate tank 19.

[0029] Figure 4 The figure shows a schematic structural view of the scraping mechanism 2 of a flotation device capable of automatically adding chemicals provided in an embodiment of the present invention. Refer to Figure 4As shown, the scraping mechanism 2 includes a central shaft 21 horizontally installed at the notch of the flotation cell 1. Both ends of the central shaft 21 are rotatably connected to the flotation cell 1. Multiple groups of scraping plates 22 are fixed on the central shaft 21. During the rotation of the central shaft 21, the scraping plates 22 can extend into the surface of the ore material and dial the generated foam floating material into the concentrate tank 19. A second driving assembly 23 for driving the rotation of the central shaft 21 is further provided at the notch of the flotation cell 1. The second driving assembly 23 can be a driving member composed of a driving motor, a transmission wheel, and a belt, or a driving member composed of a driving motor and a transmission gear, so as to drive the rotation of the central shaft 21 and realize the dialing of the ore material. In some embodiments, if multiple flotation devices are connected in series, in order to reduce the loss of redundant energy, multiple scraping mechanisms 2 can adopt the same driving structure, so that the central shafts 21 are connected to each other through couplings, and the second driving assembly 23 is arranged at the flotation cell 1 at the end, so that one second driving assembly 23 drives the rotation of multiple groups of central shafts 21, which not only reduces the occupation of redundant space, but also greatly reduces the consumption of redundant energy.

[0030] Figure 5 The structural schematic diagram of a chemical agent automatic adding device 3 in a flotation device capable of automatically adding chemical agents provided by an embodiment of the present invention is shown. Refer to Figure 3 and Figure 5 As shown, a chemical agent automatic adding device 3 for automatically adding chemical agents to the ore material is further provided inside the flotation cell 1, so as to reduce the consumption of labor through the automatic addition of chemical agents. The chemical agent automatic adding device 3 includes a main supply pipe 31 located inside the flotation cell 1, multiple groups of chemical agent equalizing mechanisms 32 arranged on the main supply pipe 31, and a chemical agent supply assembly 33 arranged outside the flotation cell 1 for supplying chemical agents to the main supply pipe 31. The main supply pipe 31 is generally made of a hard pipe material, and it is arranged inside the flotation cell 1 to have a certain supporting force to meet the support and normal operation of the chemical agent equalizing mechanism 32. In order to make the distribution of chemical agents more uniform, the main supply pipe 31 is preferably a circular structure, which is coaxial with the flotation column 13 and is located in the circular area in the middle of the flotation cell 1.

[0031] Figure 6 The structural schematic diagram of the chemical agent equalizing mechanism of a chemical agent automatic adding device in a flotation device capable of automatically adding chemical agents provided by an embodiment of the present invention is shown. Refer to Figure 6As shown, a plurality of medicine equalizing mechanisms 32 are provided and are evenly arranged along the spatial area of the main supply pipe 31. The medicine equalizing mechanism 32 includes an aggregate bowl 321, which is arranged upside down, and a connecting pipe 322 is coaxially and fixedly connected to the bottom surface thereof. The connecting pipe 322 is also made of a rigid material and is rotatably and sealingly connected to the main supply pipe 31 at the other end. When the connecting pipe 322 rotates, the aggregate bowl 321 always maintains an upside-down state and rotates around the center of the aggregate bowl 321. A power assembly 324 for driving the connecting pipe 322 to rotate is further provided on one side of the connecting pipe 322. The power assembly 324 includes a driving motor 3241 fixedly connected to the main supply pipe 31, a driving gear 3242 coaxially and fixedly connected to the output shaft of the driving motor 3241, and a driven gear ring 3243 coaxially and fixedly connected to the outer peripheral surface of the connecting pipe 322. The driving gear 3242 meshes with the driven gear ring 3243, so that when the driving motor 3241 is started, the aggregate bowl 321 is driven to rotate through the meshing of the driving gear 3242 and the driven gear ring 3243. With the addition of ore, the aggregate bowl 321 will eventually be immersed in the ore. Due to the upside-down state of the aggregate bowl 321, part of the air will be retained inside the aggregate bowl 321, thus preserving part of the space. After the medicine supply assembly 33 supplies medicine to the main supply pipe 31, the medicine will enter the inside of the aggregate bowl 321 through the connecting pipe 322 and disperse downward. Due to the working principle of the flotation equipment itself, bubbles will be generated at all times and float upward. The upside-down aggregate bowl 321 will limit the dispersion range of the medicine, and the foam floating upward at all times will also enter the inside of the aggregate bowl 321, thereby driving the ore to fully mix with the medicine in the area of the aggregate bowl 321, providing space and time for the medicine mixing. With the mixing of the medicine, the bubbles will also disperse the medicine and act on the surrounding ore. Therefore, under the natural settlement of the medicine and the impact of the bubbles, and under the limitation of the aggregate bowl 321, the mixing efficiency of the medicine is greatly increased, and the uniformity of the subsequent medicine mixing is improved.

[0032] Figure 7 The figure shows a schematic diagram of the effect of the medicine equalizing mechanism of the medicine automatic adding device in a flotation device capable of automatically adding medicine provided by an embodiment of the present invention. Refer to Figure 7As shown, as the reagent reacts, the mineral slurry carried in the bubbles enters the interior of the aggregate bowl 321. As the reagent is added, the reagent dripping on the floating foam will also affect the uniformity of the reagent dispersion. Therefore, several guide vanes 325 are fixedly connected from the bottom of the inner wall of the aggregate bowl 321 to the edge of the bowl mouth of the aggregate bowl 321. Driven by the main motor 3241, the aggregate bowl 321 rotates, and under the disturbance of the guide vanes 325, the floating materials or mineral materials in the aggregate bowl 321 flow towards the bowl mouth direction of the aggregate bowl 321 along the trend, and the flow range forms a space with a fan-shaped cross-section. As the reagent is added, the reagent will also be distributed into the fan-shaped space, and combined with the floating of the bubbles, the uniformity and efficiency of the reagent mixing are greatly improved.

[0033] To improve the safety and stability of the use of the flotation equipment, a protective shell 323 that wraps the power component 324 is also provided on the main supply pipe 31 corresponding to each power component 324. While protecting the main motor 3241, it also reduces the influence of materials on the meshing of the driving gear 3242 and the driven rack, further improving the safety and stability of the reagent automatic adding device 3.

[0034] Reference Figure 5 As shown, a lifting drive member 4 connected to the main supply pipe 31 is provided on each side of the main supply pipe 31. The lifting drive member 4 can be a hydraulic cylinder, an electric push rod, or a driving structure such as a worm and worm gear that can achieve displacement. Since the working space of the aggregate bowl 321 after rotation is a flow space with a fan-shaped cross-section, as the aggregate bowl 321 rises and falls, the working range of each aggregate bowl 321 can also be adjusted according to the actual situation, and the rise and fall of the aggregate bowl 321 can also be used to avoid the entry of excess foam.

[0035] Figure 8 The structural schematic diagram of the medicine supply component 33 of the reagent automatic adding device 3 in a flotation equipment capable of automatically adding reagents provided by the embodiment of the present invention is shown. Reference Figure 8As shown in the figure, the above-mentioned chemical feeding assembly 33 includes a chemical feeding tank 331 located outside the flotation cell 1, and a chemical feeding pump 332 connected to the chemical feeding tank 331. The inlet of the feeding pump is in communication with the inside of the chemical feeding tank 331, and the outlet of the feeding pump is connected to a chemical feeding pipe 333. The other end of the feeding pipe is movably connected to the main feeding pipe 31, so that by controlling the chemical feeding pump 332, the active addition of the chemical agent can be realized. In order to further reduce the cumbersome operation of manual chemical addition, an area sensor is also provided at the notch of the flotation cell 1. The area sensor points to the notch of the flotation cell 1, and an infrared emission end and an infrared receiving end are arranged therein, so as to monitor the foam area on the surface of the flotation cell 1. And a controller is also integrated in the area sensor, which is electrically connected to the chemical feeding pump 332. The area sensor monitors the foam area on the surface of the flotation cell 1 in real time. The staff can preset the operation logic for starting the chemical feeding pump 332 in advance. For example, when the area value detected by the area sensor is less than half of the area of the notch of the flotation cell 1, an electrical signal is transmitted to the controller and the chemical feeding pump 332 is controlled to start through the controller. Moreover, the chemical feeding pump 332 can also be controlled to start intermittently through the controller to avoid the lag of bubble generation caused by the insufficient reaction of the chemical agent, resulting in the waste phenomenon of excessive addition of the chemical agent.
