Description

Technical Field

[0001] The present disclosure relates to the technical field of phosphate rock production, and in particular to a phosphate rock flotation extraction device. Background Art

[0002] Phosphate rock is a general term for phosphate minerals that can be used economically. Phosphate rock is widely used in medicine, food, matches, dyes, sugar making, ceramics and national defense projects. The production of phosphate rock needs to go through the process of mineral processing in order to extract the required mineral particles from the phosphate rock. In the mineral processing process, flotation equipment is usually used for operation. The flotation equipment uses the flotation principle, that is, the difference in physical and chemical properties of the mineral surface is used to sort minerals. During the flotation process, mineral particles come into contact with bubbles and adhere to the surface of the bubbles. This is because the adhesion of useful minerals is poor and they are easy to form buoyancy with bubbles, thereby floating to the top of the flotation tank. Foam flotation is widely used in industry.

[0003] For example, Chinese patent document CN210545606U discloses a mineral processing device in phosphate production, including a No. 1 ball mill, the No. 1 ball mill is provided with two groups, the rear end of the No. 1 ball mill is connected to a flotation tube, the other end of the flotation tube is fixedly connected to a No. 1 flotation machine, the left and right ends of the No. 1 flotation machine are fixedly connected to a connecting tube, the other end of the connecting tube is fixedly installed with a No. 2 flotation machine, the rear left part of the No. 2 flotation machine is fixedly connected to a No. 1 discharge pipe, the left side of the No. 1 ball mill is provided with a No. 2 ball mill, the rear end of the No. 2 ball mill is fixedly installed with a No. 2 discharge pipe, and the No. 2 discharge pipe and one end of the No. 1 discharge pipe are jointly connected to a thickener. Since the mineral processing device can only save electricity costs and enhance the mixing degree between the pulp, it cannot effectively improve the effect of full contact between air and pulp, which is not conducive to the extraction of available mineral particles in the pulp, nor is it conducive to saving mineral resources.

[0004] In order to improve the effect of full contact between air and slurry, so as to improve the extraction efficiency of available mineral particles in the slurry, for example, Chinese patent document CN 217093930U discloses a phosphate ore flotation device, including a cylinder with a cylinder cover on the top, and also including an air-blowing part, a stirring part and a filtering part; the air-blowing part is arranged on the inner side of the lower part of the cylinder, the stirring part is arranged at the bottom of the cylinder, and the filtering part is arranged on the upper part of the cylinder. The above-disclosed phosphate ore flotation device can promote the rapid combination of flotation reagents and bubbles to form a mineralized foam layer by rapidly stirring the slurry and coordinating equipment for aeration, thereby shortening the flotation time.

[0005] However, the technical solution disclosed in the above-mentioned phosphate ore flotation device still has the following problems: the phosphate ore flotation device adds a stirring part at the bottom of the cylinder to stir the slurry and the flotation agent, and adds an air-blowing part on the inner wall of the cylinder. Under the joint action of the stirring part and the air-blowing part, the slurry and the flotation agent are mixed faster and the suspended slurry is pushed to the position of the foaming net of the air-blowing part, and the bubbles output by the foaming net are used to carry the available minerals to float up. However, the stirring part and the air-blowing part of the phosphate ore flotation device need to be set separately, and the overall volume is large, which makes the structural compactness of the phosphate ore flotation device poor. At the same time, because the stirring effect is still poor, there is inevitably a situation of slurry deposition at the bottom of the cylinder, which leads to the problem of poor mixed contact effect between air and slurry.

[0043] Furthermore, a plurality of first stirring blades 4310 are provided at the other end of the first stirring member 430, and a plurality of first air outlet holes 4312 are provided on the outer wall of each first stirring blade 4310, and each first air outlet hole 4312 is communicated with the first flow cavity 4301, and the first branch air port 5102 is also communicated with the first flow cavity 4301, and a plurality of second stirring blades 4410 are provided at the other end of the second stirring member 440, and a plurality of second air outlet holes 4412 are provided on the outer wall of each second stirring blade 4410, and each second air outlet hole 4412 is communicated with the second flow cavity 4401, and the second branch air port 5103 is also communicated with the second flow cavity 4401.

[0044] It should be noted that if Figure 5 and Figure 6 The directions indicated by the middle arrows are the flow directions of the air after it is filled into the first flow-through cavity 4301 and the second flow-through cavity 4401, that is, the flow directions of the air.

[0045] like Figures 3 to 6As shown, in one embodiment, a plurality of first air outlet holes 4312 are arranged at intervals on the outer wall of the corresponding first stirring blade 4310, and a plurality of second air outlet holes 4412 are arranged at intervals on the outer wall of the corresponding second stirring blade 4410. It can be understood that air can be filled into the first flow cavity 4301 and the second flow cavity 4401 through the transfer vent 510, and blown out from the plurality of first air outlet holes 4312 and the plurality of second air outlet holes 4412 respectively while the first stirring blade 4310 and the second stirring blade 4410 rotate, so as to form bubbles to drive the available mineral particles to float up, thereby not only accelerating the tumbling of the slurry, but also enabling the slurry to fully contact with the air, so as to improve the extraction efficiency of the available mineral particles in the slurry.

[0046] like Figure 3 As shown, in one embodiment, the lifting mechanism 300 includes a lifting and telescopic driving member 310 and a fixed connecting plate 320, the lifting and telescopic driving member 310 is fixedly connected to the outer wall of the box body 100, one end of the fixed connecting plate 320 is fixedly connected to the power output end of the lifting and telescopic driving member 310, and the horizontal telescopic driving member 310 is fixedly installed at the other end of the fixed connecting plate 320.

[0047] In another embodiment, the horizontal telescopic drive component 410 can be a telescopic hydraulic cylinder, a telescopic air cylinder or a telescopic electric cylinder; the lifting telescopic drive component 310 can be a telescopic hydraulic cylinder, a telescopic air cylinder or a telescopic electric cylinder.

It can be understood that the dual-axis driving motor 4210 has the effect of outputting rotational force at both ends at the same time, so that one end of the first stirring member 430 can rotate with the rotating main shaft of one end of the dual-axis driving motor 4210, and one end of the second stirring member 440 can rotate with the rotating main shaft of the other end of the dual-axis driving motor 4210, so that the dual-axis driving motor 4210 can be driven to drive the multiple first stirring blades 4310 and the multiple second stirring blades 4410 to rotate and stir at the same time, so that the effect of accelerating the turning of the slurry and the full contact between the slurry and the air can be effectively improved, and the slurry deposition at the bottom of the box body can be avoided.

[0049] like Figures 3 to 6 As shown, in one embodiment, the first stirring member 430 includes a first rotating seat 4320 and a first fixed base 4330, the first rotating seat 4320 includes a first inner shaft seat 4322 and a first outer shaft seat 4324 which are coaxially arranged, the first outer shaft seat 4324 is located on the outer side of the first inner shaft seat 4322, and the first fixed base 4330 is rotatably sealed and connected to the first rotating seat 4320, so that the first outer shaft seat 4324, the first inner shaft seat 4322 and the first fixed base 4330 together form a first process The circulation cavity 4301; a plurality of first stirring blades 4310 are fixedly connected to the end of the first outer shaft seat 4324 away from the first fixed base 4330; the first fixed base 4330 is provided with a first through hole 433a, the first inner shaft seat 4322 is provided with a first connecting circular groove 4323, the first fixed base 4330 is covered on one end of the first rotating seat 4320, and the rotating main shaft of one end of the dual-axis driving motor 4210 is fixedly connected to the first connecting circular groove 4323 through the first through hole 433a.

[0051] It can be understood that, since the rotating main shaft at one end of the dual-axis driving motor 4210 is fixedly connected to the first connecting circular notch 4323 through the first through hole 433a, the rotating main shaft at one end of the dual-axis driving motor 4210 can be driven to rotate, thereby driving the first plurality of first stirring blades 4310 on the first rotating seat 4320 to rotate. Among them, the first outer sealing bearing member 4340 is used to support the first rotating seat 4320 to be rotatably connected with the first fixed base 4330, that is, the first rotating seat 4320 rotates relative to the first fixed base 4330, while the first fixed base 4330 is fixed, which effectively increases the structural feasibility of the phosphate ore flotation extraction device 10. In this embodiment, the first outer shaft seat 4324 and the first inner shaft seat 4322 are an integrally formed structure, so that one end of the first outer shaft seat 4324 is reliably fixedly connected to one end of the first inner shaft seat 4322. It can be understood that in other embodiments, the first outer shaft seat 4324 and the first inner shaft seat 4322 can also be formed separately and welded together.

[0052] like Figures 3 to 6 As shown, in one embodiment, the second stirring member 440 includes a second rotating seat 4420 and a second fixed base 4430, the second rotating seat 4420 includes a second inner shaft seat 4422 and a second outer shaft seat 4424 which are coaxially arranged, the second outer shaft seat 4424 is located on the outer side of the second inner shaft seat 4422, and the second fixed base 4430 is rotatably sealed and connected to the second rotating seat 4420, so that the second outer shaft seat 4424, the second inner shaft seat 4422 and the second fixed base 4430 jointly form a second flow passage. The through cavity 4401; a plurality of second stirring blades 4410 are fixedly connected to the end of the second outer shaft seat 4424 away from the second fixed base 4430; the second fixed base 4430 is provided with a second through hole 443b, and the second inner shaft seat 4422 is provided with a second connecting circular groove 4423; the second fixed base 4430 is covered on one end of the second rotating seat 4420, and the rotating main shaft of the other end of the dual-axis drive motor 4210 is fixedly connected to the second connecting circular groove 4423 through the second through hole 443b.

[0053] In one embodiment, the second stirring member 440 includes a second outer sealed bearing member 4440 and a second inner sealed bearing member 4450; the outer ring of the second outer sealed bearing member 4440 is installed on the inner wall of the second flow chamber 4401, and the inner ring of the second outer sealed bearing member 4440 is sleeved on the outer wall of one end of the second fixed base 4430, so that the second rotating seat 4420 is rotatably connected to the second fixed base 4430; the outer ring of the second inner sealed bearing member 4450 is installed on the inner wall of the second connecting circular groove 4423, and the inner ring of the second inner sealed bearing member 4450 is sleeved on the outer wall of the rotating main shaft at the other end of the dual-axis drive motor 4210.

[0054] It can be understood that, since the rotating main shaft at the other end of the dual-axis driving motor 4210 is fixedly connected to the first connecting circular notch 4323 through the first through hole 433a, the rotating main shaft at one end of the dual-axis driving motor 4210 can be driven to rotate, thereby driving the plurality of second stirring blades 4410 on the second rotating seat 4420 to rotate. Among them, the second outer sealed bearing member 4440 is used to support the second rotating seat 4420 to be rotatably connected with the second fixed base 4430, that is, the second rotating seat 4420 rotates relative to the second fixed base 4430, while the second fixed base 4430 is fixed, which effectively increases the structural feasibility of the phosphate ore flotation extraction device 10. In this embodiment, the second outer shaft seat 4424 and the second inner shaft seat 4422 are an integrally formed structure, so that one end of the second outer shaft seat 4424 is reliably fixedly connected to one end of the second inner shaft seat 4422. It can be understood that in other embodiments, the second outer shaft seat 4424 and the second inner shaft seat 4422 can also be formed separately and welded together.

[0055] It should be noted that sealing materials or sealing structures are provided at the installation locations of the first outer sealed bearing component 4340 and the first inner sealed bearing component 4350 , and the second outer sealed bearing component 4440 and the second inner sealed bearing component 4450 , thereby ensuring the safety of the dual-axis drive motor 4210 .

[0056] like Figures 3 to 6 As shown, in one embodiment, the transfer ventilator 510 is a three-way connector 5110, and the three-way connector 5110 is disposed on the top of the dual-axis driving motor 4210;

[0057] The air supply mechanism 500 further includes a telescopic hose 530, a first connecting hard pipe 540 and a second connecting hard pipe 550, one end of the telescopic hose 530 is connected to the main air inlet 5101, and the other end of the telescopic hose 530 is connected to the air supply end of the air supply fan 520;

[0058] The first fixed base 4330 is further provided with a first air inlet hole 4334, one end of which is in communication with the first flow cavity 4301, the other end of which is in communication with one end of the first connecting tube 540, and the other end of which is in communication with the first branch air port 5102;

[0059] The second fixed base 4430 is also provided with a second air inlet hole 4434, one end of the second air inlet hole 4434 is connected to the second flow cavity 4401, the other end of the second air inlet hole 4434 is connected to one end of the second connecting hard tube 550, and the other end of the second connecting hard tube 550 is connected to the second branch air port 5103.

[0060] It can be understood that the air output from the air supply end of the air supply fan 520 reaches the three-way connector 5110 through the telescopic hose 530, and is then filled into the first flow chamber 4301 by the first connecting hard tube 540, and is filled into the second flow chamber 4401 by the second connecting hard tube 550, so that the air is blown out from the multiple first air outlets 4312 and the multiple second air outlets 4412 respectively and forms bubbles. With the rotation and stirring of the multiple first stirring blades 4310 and the multiple second stirring blades 4410, the slurry is accelerated to turn over, so that the slurry can be fully contacted with the air, which effectively improves the extraction efficiency of the available mineral particles in the slurry, and also makes the phosphate ore flotation extraction device 10 have a better structural integration.

[0061] like Figures 3 to 6 As shown, in one embodiment, the periphery of the telescopic through hole 102 is provided with a slide groove 103, and the box body 100 includes a sealed telescopic baffle 110, which is arranged around the outer wall of the horizontal telescopic driving member 410 and is slidably connected to the slide groove 103. It can be understood that the periphery of the telescopic through hole 102 is provided with a slide groove 103, and the box body 100 includes a sealed telescopic baffle 110, which is arranged around the outer wall of the horizontal telescopic driving member 410 and is slidably connected to the slide groove 103. It can be understood that since the sealed telescopic baffle 110 is arranged around the outer wall of the horizontal telescopic driving member 410 and is movably connected to the slide groove 103, when the horizontal telescopic driving member 410 moves horizontally and moves up and down, the sealed telescopic baffle 110 can always keep close to the outer wall of the horizontal telescopic driving member 410 to form an effective sealing effect, thereby effectively preventing the slurry from flowing out of the telescopic through hole 102, thereby improving the structural rationality of the phosphate ore flotation extraction device 10.

[0062] Compared with the prior art, the present invention has the following advantages, including but not limited to:

[0063] 1. By controlling the power output end of the lifting mechanism 300 to move up and down, the first stirring member 430 and the second stirring member 440 can be lifted and lowered in the stirring cavity 101; secondly, the power output end of the horizontal telescopic drive member 410 can also be controlled to move horizontally, so that the rotating main shafts at both ends of the drive motor 420 drive the first stirring member 430 and the second stirring member 440 to rotate, and can also move horizontally in the stirring cavity 101, thereby effectively avoiding the deposition of slurry at the bottom of the box 100, so that the slurry can be fully stirred, thereby effectively improving the effect of full contact and stirring of air and slurry.

[0064] 2. The air is transported to the main air inlet 5101 through the air supply end of the air supply fan 520, so that the air can be filled into the first flow chamber 4301 and the second flow chamber 4401 through the adapter vent 510, and blown out from the first plurality of air outlets 4312 and the second plurality of air outlets 4412 respectively while the first stirring blade 4310 and the second stirring blade 4410 rotate, so as to form bubbles to drive the available mineral particles to float up, thereby effectively improving the effect of accelerating the slurry turning and fully contacting and stirring the slurry with air, and also effectively improving the structural integration of the phosphate ore flotation extraction device 10.

[0065] 3. The use of a telescopic hydraulic cylinder, a telescopic air cylinder or a telescopic electric cylinder can provide a stable and reliable power output for the phosphate ore flotation extraction device 10. When the horizontal telescopic drive member 410 moves horizontally and lifts, the sealing telescopic baffle 110 can always keep close to the outer wall of the horizontal telescopic drive member 410 to form an effective sealing effect, thereby effectively preventing the slurry from flowing out of the telescopic through hole 102, thereby improving the structural rationality of the phosphate ore flotation extraction device 10.

[0066] 4. Air can be blown out through the multiple first air outlet holes 4312 and the multiple second air outlet holes 4412 to form bubbles. As the multiple first stirring blades 4310 and the multiple second stirring blades 4410 rotate and stir, the slurry is accelerated to turn over, so that the slurry can be fully contacted with the air, which effectively improves the extraction efficiency of the available mineral particles in the slurry, and also makes the phosphate ore flotation extraction device 10 have a better structural integration.

It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the disclosed patent shall be subject to the attached claims.
