Description

Technical Field

[0001] This invention relates to the field of gold ore flotation technology, and in particular to a gold ore flotation process and equipment. Background Technology

[0002] A flotation machine, short for flotation mineral processing machine, refers to mechanical equipment that completes the flotation process. In a flotation machine, after the slurry has been treated with reagents, it is agitated and aerated, causing some mineral particles to selectively adhere to the air bubbles. These particles float to the surface of the slurry and are scraped off to form a froth product, while the rest remain in the slurry, thus achieving the purpose of mineral separation. There are many structural forms of flotation machines, the most common being the mechanically agitated flotation machine. Traditional mechanically agitated flotation machines have limited mixing effects between air bubbles and mineral particles when flotating slurry, resulting in a relatively small number of air bubbles and generally low flotation efficiency, making it difficult to achieve high-efficiency flotation of the slurry. Gold content in ores is very low. To extract gold, the gold ore needs to be finely ground by equipment such as jaw crushers and ball mills. After that, the ore is screened by a classifier to remove particles of 0.074mm size and mixed with water to form a slurry. Then, flotation reagents are added to the slurry and stirred evenly in a mixing tank before being introduced into a flotation machine. The flotation process is used to achieve the initial separation of gold particles. Finally, the ore is processed by equipment such as thickeners and dryers to obtain gold particles of a certain purity.

[0003] A flotation device for gold ore, disclosed in CN117101878A, includes an outer casing, an inner casing, an electric telescopic rod, a feed pipe, a threaded pipe, a gas chamber, a partition, a feed hole, an air inlet, a screen plate, a fixing ring, a nut, an L-shaped bracket, a through groove, a threaded hole, and a scraper. The electric telescopic rod drives the inner casing to slide back and forth at the bottom of the outer casing, thereby forcing air drawn into the gas chamber through the upward movement of the inner casing and squeezing it into the outer casing from the bottom of the threaded pipe. Under the segmented action of multiple air inlets, the gas forms bubbles at the bottom of the slurry. Simultaneously, the reciprocating motion of the inner casing, through the threaded transmission between the nut and the screw, drives the screen plate and scraper to rotate, increasing the amount of bubbles generated while ensuring that foam floating to the surface is scraped off. Thus, a single power source can be used to achieve both bubble generation and foam removal in the slurry, resulting in a high degree of integration, reduced floor space, and lower energy consumption.

[0004] The above-mentioned technical solution has some problems in actual use. When the concentrate floats to the top of the device with the bubbles, the concentrate and foam are scraped off by the scraper. However, when separating the concentrate by the scraper, the foam is easy to stick to the scraper, resulting in poor scraping effect. Moreover, the existing similar gold ore flotation machines have limited stirring effect of the internal stirring structure, making it difficult to ensure the uniformity of bubble and material distribution. At the same time, there is also the problem that the tailings discharge pipe is easily blocked due to the high density of the tailings.

[0005] Therefore, it is necessary to invent a gold ore flotation process and equipment to solve the above problems. Summary of the Invention

A transmission sleeve is fixedly provided in the middle of the lower surface of the connecting seat, and the transmission sleeve is provided through the middle of the bottom end of the raw material tank. A wave-shaped sliding groove is provided around the outer wall of the transmission sleeve. A fixed sleeve is sleeved on the outer side of the transmission sleeve, and the fixed sleeve is fixedly provided in the middle of the lower surface of the raw material tank. A slider is fixedly provided at the bottom end of the inner side wall of the fixed sleeve, and the slider is provided inside the sliding groove. A spline shaft is fixedly provided at the bottom end of the transmission sleeve, and a bushing is sleeved on the outer side of the spline shaft.

[0013] Preferably, a transmission rod is provided through the inside of the transmission sleeve, and multiple stirring blades are arranged around the top of the transmission rod. The multiple stirring blades are all located at the bottom of the feed pipe. The top cross-section of the multiple stirring blades is an "S" shaped structure, and the outer side of the multiple stirring blades is set as an inclined structure. A reinforcing ring is arranged around the bottom of the outer wall of the stirring blade.

[0014] Preferably, a transmission bevel gear is fixedly provided at the bottom end of the bushing and the bottom end of the transmission rod, and the two transmission bevel gears are arranged symmetrically. A drive bevel gear is provided between the two transmission bevel gears. A drive motor is fixedly provided on the outer side of the drive bevel gear, and a bracket is fixedly provided on one side of the drive motor. The bracket is fixedly provided on the lower surface of the raw material tank.

[0015] Preferably, the discharge assembly includes a fine material trough, which is fixedly disposed on the outer top of the raw material trough; a ring-shaped water guide pipe is fixedly disposed on the top of the fine material trough, and multiple water spray nozzles are arranged around the inner side wall of the water guide pipe; discharge ports are provided through the bottom ends of both sides of the fine material trough.

[0016] Preferably, the feed pipe is internally fixed with multiple sets of inclined guide plates, and the inclination directions of adjacent guide plates are opposite.

[0017] Preferably, a partition is fixedly provided on the upper surface of the guide plate, and the partition is perpendicular to the guide plate, and a feeding pipe is fixedly provided at the top end of the feed pipe.

[0018] Preferably, an air supply component is fixedly connected to the bottom of the raw material tank, and the air outlet of the air supply component is connected to the bottom of the raw material tank.

[0019] This invention also discloses a mineral processing technology for gold ore flotation equipment, comprising the following steps:

[0020] Step 1: Ore pretreatment. The gold ore raw material to be beneficiated is crushed and then screened to make slurry.

[0021] Step 2: Raw material feeding. The slurry made from gold ore raw materials and flotation reagents are fed into the tank assembly through the feeding component.

[0022] Step 3: Concentrate separation. The slurry separates inside the tank assembly. The concentrate floats to the top of the tank assembly with the bubbles and overflows into the discharge assembly.

[0023] Step 4: Discharge. The concentrate in the discharge assembly is discharged from the device after being washed with water, thus completing the flotation of the gold ore.

[0024] The technical effects and advantages of this invention are as follows:

[0025] 1. This invention sets up a tank assembly with a mixing component inside. After the slurry is injected into the tank assembly, bubbles are generated by the mixing component. The concentrate in the slurry floats to the top of the tank assembly with the bubbles. The mixing component can drive the concentrate and bubbles to rotate at the top of the tank assembly, so that the concentrate moves to the discharge component under the action of centrifugal force, thereby achieving the separation of the concentrate. Compared with the use of scraper to separate the concentrate, it can improve the flotation efficiency while ensuring the flotation accuracy.

[0026] 2. This invention incorporates a mixing component, including a movable plate. The inner side of the movable plate has multiple pusher plates for rotating the slurry. A transmission sleeve is positioned below the movable plate, driving the movable plate to rotate. A wave-shaped groove is provided on the outer side of the transmission sleeve, with a fixed slider inside. When the transmission sleeve rotates, the groove and slider cooperate, causing the transmission sleeve to drive the movable plate up and down. This controls the intermittent discharge of concentrate, effectively controlling the discharge rate of the concentrate under centrifugal force. This prevents the concentrate from continuously being subjected to centrifugal force and detaching from the discharge component, thus ensuring the flotation separation effect of the concentrate.

[0027] 3. This invention incorporates a feeding assembly, including a feed pipe, through which slurry and flotation reagents are fed. Multiple inclined guide plates are installed inside the feed pipe, with baffles on their upper surfaces. These guide plates guide the slurry, causing it and flotation reagents to change direction multiple times, thus improving the mixing effect. Each time the slurry and flotation reagents change direction, they are separated into two parts by the baffles. Each time the slurry and flotation reagents pass through a baffle, the number of times they are separated increases, further enhancing the mixing effect. The guide plates and baffles effectively improve the mixing effect of the slurry and flotation reagents, thereby improving the flotation effect of gold ore.

[0028] 4. This invention features an elastic part fixedly connected to the underside of each movable push plate. The elastic part is made of elastic material and its bottom contacts the bottom of the raw material tank. On the one hand, during rotation, the elastic part can push the tailings at the bottom of the raw material tank to the discharge pipe and discharge them. On the other hand, when the elastic part moves to the position of the discharge pipe, it can seal the inlet of the discharge pipe. The movable plate can drive the elastic part to move further downward and further compress the inside of the discharge pipe, increasing the pressure in the tailings slurry blocked inside the discharge pipe, thereby clearing the blockage. This reduces the probability of blockage in the discharge pipe, ensures the normal discharge of tailings, and thus ensures the normal operation of the entire production process.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] This invention provides, for example Figures 1 to 11 The gold ore flotation equipment shown includes a tank assembly 1, a feeding assembly 2, a discharging assembly 3, a mixing assembly 4, and a frame 5. The feeding assembly 2 is located in the middle of the tank assembly 1, the discharging assembly 3 is located at the top outer side of the tank assembly 1, and the mixing assembly 4 is located inside the tank assembly 1. The tank assembly 1, the feeding assembly 2, the discharging assembly 3, and the mixing assembly 4 are all located inside the frame 5.

[0044] The tank assembly 1 includes a raw material tank 101, and a plurality of overflow ports 102 are arranged around the top of the outer side wall of the raw material tank 101.

[0045] The feeding assembly 2 includes a feeding pipe 201. Multiple support plates 202 are arranged around the top of the outer side of the feeding pipe 201, and the support plates 202 are fixedly arranged above the raw material tank 101. Specifically, multiple sets of inclined guide plates 203 are fixedly arranged inside the feeding pipe 201, and the inclination directions of two adjacent guide plates 203 are opposite. The inclined guide plates 203 can guide the movement direction of the slurry and flotation reagents, thereby improving the mixing effect of the two.

[0046] More specifically, a partition 204 is fixedly installed on the upper surface of the guide plate 203, and the partition 204 is perpendicular to the guide plate 203. A feed pipe 205 is fixedly installed at the top of the feed pipe 201. The feed pipe 205 is used to connect to the material pump to realize the conveying of slurry and flotation reagents.

[0047] The discharge assembly 3 includes a concentrate trough 301, which is fixedly installed at the top outer side of the raw material trough 101. Specifically, a ring-shaped water guide pipe 302 is fixedly installed at the top of the concentrate trough 301. A water pump is connected to the middle of the water guide pipe 302. During use, the water pump continuously delivers clean water into the water guide pipe 302. Multiple water spray nozzles 303 are arranged around the inner side wall of the water guide pipe 302. The position of the water spray nozzles 303 corresponds to the position of the overflow port 102. After the concentrate is discharged through the overflow port 102, it can be directly rinsed by the clean water sprayed from the water spray nozzles 303. Discharge ports 304 are provided through the bottom of both sides of the concentrate trough 301.

[0048] The mixing component 4 includes a ring-shaped movable plate 401, which is located at the top of the inside of the raw material tank 101. Multiple overflow channels 402 are arranged around the top of the movable plate 401. The overflow channels 402 cooperate with the overflow port 102 to effectively control the discharge position of the concentrate, so that the discharged concentrate can be directly washed by the water sprayed from the water nozzle 303 to complete the discharge and collection of the concentrate.

[0049] Specifically, the top of the movable plate 401 is provided with a ring-shaped fixed plate 403, and multiple push plates 404 are arranged around the fixed plate 403 and the movable plate 401. Multiple extension plates 405 are fixedly provided at the bottom of the movable plate 401, and a ring-shaped movable seat 406 is fixedly provided at the bottom of the extension plate 405. Multiple movable push plates 407 are arranged around the inner side wall of the movable seat 406, and the movable push plates 407 are set with a stepped structure. The stepped structure makes the contact area between the movable push plate 407 near the outer side and the slurry larger, thereby ensuring the effect of the movable push plate 407 on the slurry.

[0050] More specifically, each movable push plate 407 has an elastic part 422 fixedly connected to its lower side. The elastic part 422 is made of elastic material and its bottom is in contact with the bottom of the raw material tank 101. As the movable plate 401 rotates, the elastic part 422 rotates synchronously, pushing the material at the bottom of the raw material tank 101 and assisting in the discharge of tailings. The elastic part 422 is elastic, and its bottom remains in contact with the bottom of the raw material tank 101 during the up-and-down sliding process of the movable plate 401. During the rotation and up-and-down movement of the movable plate 401, it not only pushes the tailings from the raw material tank 101 to the discharge pipe 6, but also provides a good up-and-down stirring effect.

[0051] More specifically, a connecting seat 408 is provided in the middle of the movable plate 401, and each movable push plate 407 is fixedly connected to the connecting seat 408. A transmission sleeve 409 is fixedly provided in the middle of the lower surface of the connecting seat 408, and the transmission sleeve 409 is provided through the middle of the bottom end of the raw material tank 101. A wave-shaped sliding groove 410 is provided around the outer wall of the transmission sleeve 409. A fixed sleeve 411 is sleeved on the outer side of the transmission sleeve 409, and the fixed sleeve 411 is fixedly provided in the middle of the lower surface of the raw material tank 101. A slider 4 is fixedly provided at the bottom end of the inner side wall of the fixed sleeve 411. 12. The slider 412 is located inside the slide groove 410. The slider 412 is fixed. When the transmission sleeve 409 rotates, the slider 412 presses against the inner wall of the slide groove 410, causing the transmission sleeve 409 to move up and down. A spline shaft 416 is fixedly installed at the bottom end of the transmission sleeve 409. A bushing 417 is sleeved on the outside of the spline shaft 416. The spline shaft 416 and the bushing 417 cooperate to realize the power transmission of the transmission sleeve 409 while ensuring that the transmission sleeve 409 can move up and down. The up and down movement of the transmission sleeve 409 drives the movable plate 401 to move up and down.

[0052] Furthermore, a discharge pipe 6 is provided at the bottom of the raw material tank 101. A control valve is fixedly connected to the end of the discharge pipe 6 to control its opening or closing. During use, the elastic part 422 pushes the tailings material at the bottom of the raw material tank 101 into the discharge pipe 6. Opening the control valve allows the tailings material to be discharged from the raw material tank 101, thus achieving tailings discharge. An air supply component 7 is fixedly connected to the bottom of the raw material tank 101. The air outlet of the air supply component 7 is connected to the bottom of the raw material tank 101. During equipment operation, the air supply component 7 continuously supplies a large number of tiny air bubbles into the raw material tank 101, causing the slurry in the raw material tank 101 to generate more air bubbles and improving the flotation efficiency.

[0053] Furthermore, a transmission rod 413 is internally installed through the transmission sleeve 409. Multiple stirring blades 414 are arranged around the top of the transmission rod 413, and all stirring blades 414 are located at the bottom of the feed pipe 201. The top profile of each stirring blade 414 is an "S" shape, and the outer sides of each stirring blade 414 are inclined. A reinforcing ring 415 is arranged around the bottom of the outer wall of each stirring blade 414. The stirring blades 414 can achieve stirring and conveying of the slurry, and the tops of the stirring blades 414 are inserted into the feed pipe 201 to ensure effective stirring and conveying of the slurry. The air outlet of the air supply component 7 corresponds to the transmission rod 13. During the rotation of the stirring blades 414, the air entering the air supply component allows for better dispersion, optimizing the flotation effect.

[0054] Meanwhile, both the bottom end of the bushing 417 and the bottom end of the transmission rod 413 are fixedly provided with transmission bevel gears 418, and the two transmission bevel gears 418 are arranged symmetrically. A driving bevel gear 419 is provided between the two transmission bevel gears 418. Both transmission bevel gears 418 mesh with the driving bevel gear 419. A drive motor 420 is fixedly provided on the outside of the driving bevel gear 419. The output shaft of the drive motor 420 is fixedly connected to the driving bevel gear 419. A bracket 421 is fixedly provided on one side of the drive motor 420, and the bracket 421 is fixedly provided on the lower surface of the raw material tank 101. The drive motor 420 is used to provide power to the stirring blade 414 and the movable plate 401.

[0055] In summary, when this device is used for flotation of gold ore, the gold ore slurry can be mixed with flotation reagents and fed into the tank assembly 1 through the feed assembly 2. Under the stirring of the mixing assembly 4, bubbles are generated. The concentrate in the slurry can float to the top of the tank assembly 1 with the bubbles, and then flow into the discharge assembly 3. After being rinsed with clean water, the concentrate is separated, thus achieving the effect of gold ore flotation.

[0056] When the slurry is fed through the feed assembly 2, the slurry and flotation reagents are transported into the feed pipe 201 by the action of the raw material pump. Under the guidance of multiple guide plates 203, the slurry and flotation reagents move downward in the feed pipe 201 and change their direction of movement multiple times. Whenever the slurry and flotation reagents move to the position of a guide plate 203, they are separated into two parts by the partition plate 204. After multiple movements, the slurry and flotation reagents are fully mixed to facilitate the subsequent flotation work.

[0057] After the slurry and flotation reagents are thoroughly mixed, they move to the bottom of the feed pipe 201. At this time, the drive motor 420 drives the transmission rod 413 to rotate, which in turn drives multiple stirring blades 414 to rotate. The stirring blades 414 move the slurry and flotation reagents, causing them to diffuse outward. During this process, the concentrate in the slurry moves upward with the bubbles generated by the stirring. Simultaneously, the air supply component 7 continuously supplies air into the feed tank 101 to ensure that bubbles can be generated stably and continuously. When the concentrate and bubbles move to the top of the feed tank 101, the drive motor 420... The motor 420 drives the transmission sleeve 409 to rotate via the bushing 417 and the splined shaft 416. The transmission sleeve 409, in turn, drives the movable plate 401 to rotate via the connecting seat 408 and the extension plate 405. During this process, on one hand, the movable plate 401 drives the concentrate and bubbles to rotate via the pusher plate 404, causing the concentrate and bubbles to move outwards under centrifugal force, ensuring that the concentrate and bubbles can move into the concentrate tank 301. On the other hand, the transmission sleeve 409 moves up and down under the action of the slide groove 410 and the slider 412, thereby causing the movable plate 401 to... The moving plate 401 moves up and down. When it moves upward, the top of the rotating plate 401 is higher than the slurry surface. At this time, the concentrate stops being discharged, allowing the slurry and flotation reagents to remain in the feed tank 101 for a longer period, ensuring thorough mixing. Simultaneously, it accumulates bubbles containing concentrate, preventing the slurry from flowing out rapidly due to continuous flow, which would affect the flotation effect. When the moving plate 401 moves downward, the top of it is level with the slurry surface. At this time, the concentrate can pass through the overflow tank 402 and overflow port 102 and be discharged. The up-and-down movement of the moving plate 401 achieves the desired concentration of concentrate. Intermittent discharge prevents the concentrate from being continuously subjected to centrifugal force and rapidly escaping from the concentrate tank 301, thus ensuring the collection effect of the concentrate. Thirdly, during the rotation and up-and-down movement of the movable plate 401, it drives the push plate 407 and the elastic part 422 below it to rotate and move up and down. During this rotation and up-and-down movement, the push plate 407 and the elastic part 422 can better agitate the material and bubbles at the bottom, effectively preventing sedimentation, improving bubble dispersion, and allowing the bubbles to better capture gold ore particles, thereby improving the separation effect. Furthermore, during rotation, the elastic part 422 can also push the tailings at the bottom of the raw material tank 101, ensuring that the tailings are promptly discharged into the discharge pipe 6.

[0058] Furthermore, through optimization of the structure of the discharge pipe 6 and the elastic part 422, when the elastic part 422 moves to the position of the discharge pipe 6, the elastic part 422 can seal the inlet of the discharge pipe 6, that is, as Figure 12 As shown in (a). Simultaneously, by setting the position of the discharge pipe 6 and the shape of the elastic part 422, when the elastic part 422 rotates and moves up and down with the movable plate 401, when the elastic part 422 moves to the position that seals the discharge pipe 6, the movable plate 401 can simultaneously drive the elastic part 422 to move further downwards, i.e. Figure 12 As shown in (b). This design is because the tailings discharged into the discharge pipe 6 have a high density and poor fluidity, making them prone to blockage. When blockage occurs in the discharge pipe 6, the elastic part 422 moves to the position of the discharge pipe 6 and forms a seal. As the movable plate 401 drives the elastic part 422 to move further downward, it can further compress the inside of the discharge pipe 6, increasing the pressure in the tailings slurry that is blocked inside the discharge pipe 6, thereby clearing the blockage. This reduces the probability of blockage in the discharge pipe 6, ensures the normal discharge of tailings, and thus ensures the normal operation of the entire production process.

[0059] After the concentrate moves to the concentrate tank 301, the water in the water pipe 302 is sprayed out through the water nozzle 303 to rinse the concentrate and eliminate air bubbles. The rinsed concentrate can be discharged through the discharge port 304 to complete the flotation treatment of the concentrate.

[0060] This invention also provides a mineral processing technology for gold ore flotation equipment, comprising the following steps:

[0061] Step 1: Ore pretreatment. The gold ore raw material to be beneficiated is crushed and then screened to make slurry.

[0062] Gold ore raw materials can be crushed using grinding equipment such as jaw crushers and sand mills. After crushing, the gold ore raw materials are screened to prepare slurry.

[0063] Step 2: Raw material feeding. The slurry made from gold ore raw materials and flotation reagents are fed into the tank assembly 1 through the feed assembly 2.

[0064] The feed assembly 2 can improve the mixing effect of slurry and flotation reagents while realizing the feeding of slurry, so as to facilitate subsequent mineral processing operations;

[0065] Step 3: Concentrate separation. The slurry is separated inside the tank assembly 1. The concentrate floats to the top of the tank assembly 1 with the bubbles and overflows into the discharge assembly 3.

[0066] Step 4: Discharge. The concentrate in the discharge assembly 3 is discharged from the device after being washed with water, thus completing the flotation of gold ore.

[0067] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
