Abstract

Described is a double-linked-wheel spray stirring mechanism and a spray atomizing floatation device with same. The double-linked-wheel spray stirring mechanism comprises a floatation tank, a supporting frame, a pre-treatment cabin, a rotary connecting rod, a driving impeller, a stirring impeller, a guide cylinder, and a circulating pump. A spray atomizing apparatus comprises an atomizing cylinder, a rotating shaft, laminar flow guide discs, a conical guide hood, an atomizing turn plate and a secondary atomizing shear mechanism or supercharging mixing conveying mechanism. The present invention makes full use ofjet energy of ore pulp sent by the circulating pump and used for the spray of an annular jet nozzle, which realizes the effective utilization of the energy and reduces the energy consumption. Moreover, a capturing agent prereacts with the ore pulp to change the surface hydrophobicity of minerals, thereby providing a good adsorption interface for the high-efficiency mineralization with bubbles. Meanwhile, the foaming agent is pre-atomized and then contacts air, so that the broken bubbles are in an atmosphere inhibiting the conglomeration, thereby keeping the stability of a micro-bubble system, and improving a floatation effect.

Description

DOUBLE-LINKED-WHEEL SPRAY STIRRING MECHANISM AND SPRAY ATOMIZING
FLOATATION DEVICE WITH SAME Technical Field The present invention relates to the technical field of manufacturing of mineral machinery, in particular to a floatation device for separating ore particles, and more particularly relates to a double-linked-wheel spray stirring mechanism and a spray atomizing floatation device with same.
Background Floatation is foam floatation and is a process of separating minerals from ore pulp by virtue of a buoyancy force of bubbles according to the difference of surface properties of various minerals. A floatation machine is mainly used for the technical field of the floatation of complex refractory minerals and is mainly applied to the fields of coal slime, quartz minerals, etc. At present, the floatation machines widely used by ore dressing plants and coal preparation plants in China are spray-type floatation machines and mechanical-stirring floatation machines. Specifically, for example, during the floatation of fine-particle coal, at a floatation stage, since the common spray-type floatation machine is not provided with a stirring apparatus, when the ore pulp has a high concentration, no sufficient power can be provided to realize the full mixing and dispersion of the ore pulp, the bubbles and floatation chemicals. High rotation speed of the stirring apparatus of the mechanical-stirring floatation machine requires high energy consumption, while low rotation speed cannot form a good flow field and suction intensity. Moreover, in the prior art, generally a surface active agent-foaming agent is directly placed in the ore pulp to be stirred, but the surface active agent-foaming agent cannot be fully dispersed, a formed micro-bubble system is unstable, and the surface active agent-foaming agent cannot be better and more uniformly mixed with the floated minerals, so the floatation effect is poor.
Therefore, how to provide a double-linked-wheel spray stirring mechanism with simple structure, good power effect, good stirring effect, low energy consumption and good floatation effect, and a spray atomizing device with same is a problem to be urgently solved by those skilled inthe art.
Summary In view of this, the present invention provides a double-linked-wheel spray stirring mechanism with simple structure, good power effect, good stirring effect, low energy consumption and good floatation effect, and a spray atomizing floatation device with same.
In order to realize the above purpose, the present invention adopts the following technical solution: a double-linked-wheel spray stirring mechanism comprises a floatation tank, a supporting frame, a pre-treatment cabin, a rotary connecting rod, a driving impeller, a stirring impeller, a guide cylinder, a centrifugal stirring sieve and a circulating pump.
The supporting frame is mounted at an upper opening of the floatation tank. The lower end of the pre-treatment cabin is fixed on the supporting frame, and the side wall is connected with annular jet nozzles. The lower end of the pre-treatment cabin is provided with a discharging opening, and the discharging opening is fixed on the upper end of the guide cylinder. The upper end of the rotary connecting rod is rotatably connected with the top end of the pre-treatment cabin through a bearing, and the lower end extends through the discharging opening to be below the guide cylinder. The driving impeller is fixed on the rotary connecting rod located in the pre- treatment cabin and corresponds to the annular jet nozzles. The stirring impeller is fixed on the lower end of the rotary connecting rod, the bottom of the floatation tank is communicated with the circulating pump, and an outlet end of the circulating pump is connected and communicated with inlet ends of the annular jet nozzles. The centrifugal stirring sieve is arranged in the pre-treatment cabin, and a middle portion of the centrifugal stirring sieve is fixedly sleeved on the rotary connecting rod. The outer side end of the centrifugal stirring sieve is correspondingly located below the annular jet nozzles.
The present invention adopts a double impeller stirring mode. The circulating pump pumps the circulating ore pulp, and the calculating ore pump is sprayed out from the annular jet nozzles to provide a power source to the driving impeller, so that the driving impeller serves as a stirring mechanism for primary mixing and stirring in the pre-treatment cabin. Liquid sprayed out by the annular jet nozzles can also be used to drive the rotary connecting rod and the stirring impeller to rotate. The stirring impeller can form the secondary stirring mixing, so that the power of the circulating pump can be fully used, the energy waste caused by the submerged spray of the spray- type floatation machine can be avoided, and the energy is further effectively used. Moreover, by adopting the double-impeller design, more uniformity in stirring can be achieved. The centrifugal stirring sieve can re-disperse the primarily mixed ore pulp under the effect of a centrifugal force to form a great amount of bubbles, so that the capturing agent and the foaming agent can perform more floatation far the ore pulp, and the floatation effect is better.
Further, the double-linked-wheel spray stirring mechanism also comprises an ore pulp circulating feeding pipe, a capturing agent adding pipe and an atomized chemical adding pipe. The annular jet nozzle comprises an outer nozzle a and an inner nozzle b embedded in the outer nozzle a. The inner nozzle b is communicated with the ore pulp circulating feeding pipe. The atomized chemical adding pipe is communicated with the outer nozzle a. The capturing agent adding pipe is used as an injected pipe and communicated with the ore pulp circulating feeding pipe. An outlet end of the circulating pump is connected and communicated with the ore pulp circulating feeding pipe.
By adopting the above technical solution, the annular jet nozzles of the present invention perform the multilevel injection effect. Through the injection effect of the inner nozzle b, the pre-
action of the emulsified capturing agent on the ore pulp is realized to change the hydrophobicity and to provide a good adsorption interface. Then through the injection effect of the outer nozzle a, the atomized and foamed surface-active agent-foaming agent is uniformly mixed with the modified ore pulp, so that the efficient pre-mixing of the bubbles and the ore pulp can be realized. Meanwhile, the energy of the annular jet nozzles is used to drive the driving impeller to rotate, so that the energy waste caused by the submerged spray of the spray-type floatation machine can be avoided, and the energy is further effectively utilized.
Further, the pre-treatment cabin comprises a columnar section and an inverted conical section. The discharging opening is arranged at the lower end of the inverted conical section and fixed at a mounting hole. The centrifugal stirring sieve is of an inverted conical shape, and the conicity of the centrifugal stirring sieve is identical to that of the conical section of the pre-treatment cabin.
By adopting the above technical solution, the centrifugal stirring sieve of the present invention is of an inverted conical shape, that is, a stirring space is formed in the pre-treatment cabin, so that the emulsified capturing agent and the atomized and foamed surface active agent-foaming agent can be primarily fully and better mixed with the ore pulp from the circulating pump. Moreover, through the stirring of the driving impeller, the primarily mixed ore pulp can also be re- dispersed by the centrifugal stirring sieve under the effect of the centrifugal force to form a great amount of bubbles, so that the capturing agent and the foaming agent can perform more floatation for the ore pulp.
Further, the double-linked-wheel spray stirring mechanism also comprises a closed hood. The closed hood is of a horn shape, and the lower end of the closed hood is fixed at the lower end of the guide cylinder; and the stirring impeller is located in the closed hood.
Further, the double-linked-wheel spray stirring mechanism also comprises guide partition plates. Each guide partition plate comprises a vertical plate and an arc plate. The vertical plate is disposed between the closed hood and the wall of the floatation tank, and a finished ore concentration area is formed between the vertical plate and the wall of the floatation tank. One end of the arc plate is connected to the upper end of the vertical plate, and the other end of the arc plate inclines downwards. The wall of the floatation tank is correspondingly provided with an ore pulp inlet and an ore pulp outlet, and the lower end of the arc plate corresponds to the ore pulp inlet and the ore pulp outlet.
By adopting the above technical solution, through the closed hood, the stirring impeller fully re-mixes the ore pulp, mixed with the capturing agent and the foaming agent, and the ore pulp in the floatation tank, and through the effect of the capturing agent and the foaming agent, the bubbles can be efficiently mineralized to provide a good adsorption mixing effect.
Further, the double-linked-wheel spray stirring mechanism also comprises a false bottom and a support column. The false bottom is fixed on the bottom of the floatation tank through the support column, and the outer side end extends to a position close to the inner side of the vertical plate.
Further, a scraper mechanism comprises a rotating shaft support, scraper rotating shafts and scrapers. The rotating shaft support is arranged at the upper end of the floatation tank. The scraper rotating shafts are arranged on the rotating shaft support, and one end of each scraper rotating shaft is fixedly connected with an outer driving motor output end, and a plurality of scrapers are uniformly and fixedly mounted on each scraper rotating shaft. The scrapers are located above the finished ore concentration area.
By adopting the above technical solution, in the present invention, after being thrown out from the outer edge of blades of the stirring impeller, the floatation mineralized foams float upwardly to a liquid surface above a floatation area, are fully accumulated at the upper ends of the guide partition plates, and are scraped off the floatation tank by the scrapers, while the mineralized foams that are not scraped deposit down to the finished ore concentration area. The mineralized foams that are settled down in the finished ore concentration areas at both sides sink to the lower ends of the guide partition plates and pass by the guide partition plates respectively to reach the floatation area so as to realize the re-floatation. The ore pulp settled to the bottom of the floatation tank enters the next floatation tank via the ore pulp inlet to perform the re-floatation.
A spray atomizing floatation device comprises the above double-linked-wheel spray stirring mechanism and a spray atomizing apparatus. The spray atomizing apparatus comprises an atomizing cylinder, a rotating shaft, laminar flow guide discs and an atomizing turnplate. The upper end of the atomizing cylinder is provided with a close cover. The rotating shaft is arranged in the atomizing cylinder along an axial direction of the atomizing cylinder, and the upper end of the rotating shaft is rotatably connected with the close cover through a bearing.
The laminar flow guide discs are divided into multiple layers and are provided with mounting holes in the middle portion. A plurality of laminar flow guide discs are fixedly sleeved on the rotating shaft at intervals and are provided with drainage holes in an area close to the rotating shaft.

Compared with the existing floatation process that the final energy of chemical and pulp conveying is all converted into internal energy consumed in a pulp mixing device and the floatation tank, the present invention makes full use of the jet energy of the ore pulp sent by the circulating pump and used for the spray of the annular jet nozzles to drive the spray atomizing apparatus to drive the pre-treatment stirring mechanism for pulp mixing pre-treatment, which realizes the effective utilization of the energy and reduces the energy consumption. The structural design and the working process give full consideration to the pre-treatment effect of the capturing agent on the ore pulp and the effect of the atomized foaming agent on generating the bubbles, and enable the capturing agent to pre-react with the ore pulp to change the surface hydrophobicity of the minerals, thereby providing a good adsorption interface for the efficient mineralization with the bubbles. Meanwhile, the foaming agent is pre-atomized and then contacts the air, so that the broken bubbles are in the atmosphere inhibiting the conglomeration, thereby keeping the stability of the micro-bubble system. Through multi-time shearing and turbulent mixing, the micro-bubble system is more balanced to provide a sufficient contact opportunity for the efficient mineralization of the bubbles, thereby greatly improving the mineralization efficiency, and improving the floatation effect.

Detailed Description The technical solutions in the embodiments will be clearly and fully described below in combination with the drawings in the embodiments. Apparently, the described embodiments are merely part of the embodiments, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those ordinary skilled in the art without contributing creative labour will belong to the protection scope of the embodiments.
As shown in Fig. 1, a double-linked-wheel spray stirring mechanism includes a floatation tank 51, a supporting frame, a pre-treatment cabin 5311, a rotary connecting rod 5342, a driving impeller 5341, a stirring impeller 5343, a guide cylinder 532, a centrifugal stirring sieve 5344 and a circulating pump 520.
The supporting frame (not shown in the figure) is mounted at an upper opening of the floatation tank 51. The lower end of the pre-treatment cabin 5311 is fixed on the supporting frame, and the side wall is connected with annular jet nozzles 5312. The lower end of the pre-treatment cabin 5311 is provided with a discharging opening, and the discharging opening is fixed on the upper end of the guide cylinder 532. The upper end of the rotary connecting rod 5342 is rotatably connected with the top end of the pre-treatment cabin 5311 through a bearing, and the lower end extends through the discharging opening to be below the guide cylinder 532. The driving impeller 5341 is fixed on the rotary connecting rod 5342 located in the pre-treatment cabin 5311 and corresponds to the annular jet nozzles 5312. The stirring impeller 5343 is fixed at the lower end of the rotary connecting rod 5342, the bottom of the floatation tank 51 is communicated with the circulating pump 520, and an outlet end of the circulating pump 520 is connected and communicated with inlet ends of the annular jet nozzles 5312. The centrifugal stirring sieve 5344 is arranged in the pre-treatment cabin 5311, and a middle portion of the centrifugal stirring sieve is fixedly sleeved on the rotary connecting rod 5342. The outer side end of the centrifugal stirring sieve 5344 is correspondingly located below the annular jet nozzles 5312.
The present embodiment adopts a double-impeller stirring mode. The circulating pump 520 pumps the circulating ore pulp, and the calculating ore pump is sprayed out from the annular jet nozzles 5312 to provide a power source to the driving impeller 5341, so that the driving impeller 5341 serves as a stirring mechanism for primary mixing and stirring in the pre-treatment cabin
5311. Liquid sprayed out by the annular jet nozzles 5312 can also be used to drive the rotary connecting rod 5342 and the stirring impeller 5343 to rotate. The stirring impeller 5343 can form the secondary stirring mixing, so that the power of the circulating pump 520 can be fully used, the energy waste caused by the submerged spray of the spray-type floatation machine can be avoided, and the energy is further effectively used. Moreover, by adopting the double-impeller design, more uniformity in stirring can be achieved. The centrifugal stirring sieve 5344 can re- disperse the primarily mixed ore pulp under the effect of a centrifugal force to form a great amount of bubbles, so that the capturing agent and the foaming agent can perform more floatation for the ore pulp, and the floatation effect is better.
The present embodiment also includes an ore pulp circulating feeding pipe 5317, a capturing agent adding pipe 5314 and an atomized chemical adding pipe 5315. Each annular jet nozzle 5312 includes an outer nozzle 5312a and an inner nozzle 5312b embedded in the outer nozzle 5312a. The inner nozzle 5312b is communicated with the ore pulp circulating feeding pipe 5317. The atomized chemical adding pipe 5315 is communicated with the outer nozzle 5312a. The capturing agent adding pipe 5314 is used as an injected pipe and communicated with the ore pulp circulating feeding pipe 5317. An outlet end of the circulating pump 520 is connected and communicated with the ore pulp circulating feeding pipe 5317.
In the present embodiment, the annular jet nozzles 5312 perform the multilevel injection effect. Through the injection effect of the inner nozzle 5312b, the pre-action of the emulsified capturing agent on the ore pulp is realized to change the hydrophobicity and to provide a good adsorption interface. Then through the injection effect of the outer nozzle 5312a, the atomized and foamed surface-active agent-foaming agent is uniformly mixed with the modified ore pulp, so that the efficient pre-mixing of the bubbles and the ore pulp can be realized. Meanwhile, the driving impeller 5341 is driven by the energy of the annular jet nozzles 5312 to rotate, so that the energy waste caused by submerged spray of the spray-type floatation machine can be avoided, and the energy is further effectively utilized.
In the present embodiment, the pre-treatment cabin 5311 includes a columnar section and an inverted conical section. The discharging opening is arranged at the lower end of the inverted conical section and fixed at the mounting hole. The centrifugal stirring sieve 5344 is of an inverted conical shape, and the conicity of the centrifugal stirring sieve is identical to that of the conical section of the pre-treatment cabin 5311. In the present embodiment, the centrifugal stirring sieve 5344 is of the inverted conical shape, that is, a stirring space is formed in the pre-treatment cabin 5311, so that the emulsified capturing agent and the atomized and foamed surface active agent-foaming agent can be primarily fully and better mixed with the ore pulp from the circulating pump 520. Through the stirring of the driving impeller 5341, the primarily mixed ore pulp can also be re-dispersed by the centrifugal stirring sieve 5344 under the effect of the centrifugal force to form a great amount of bubbles, so that the capturing agent and the foaming agent can perform more floatation for the ore pulp.
The present embodiment also includes a closed hood 5331. The closed hood 5331 is of a horn shape, and the lower end of the closed hood is fixed at the lower end of the guide cylinder 532; and the stirring impeller 5343 is located in the closed hood 5331.
The present embodiment also includes guide partition plates 516. Each guide partition plate 516 includes a vertical plate and an arc plate. The vertical plate is disposed between the closed hood 5331 and the wall of the floatation tank 51, and a finished ore concentration area 517 is formed between the vertical plate and the wall of the floatation tank 51. One end of the arc plate is connected to the upper end of the vertical plate, and the other end of the arc plate inclines downwards. The wall of the floatation tank 51 is correspondingly provided with an ore pulp inlet 511 and an ore pulp outlet 512, and the lower end of the arc plate corresponds to the ore pulp inlet 511 and the ore pulp outlet 512.
In the present embodiment, through the closed hood 5331, the stirring impeller 5343 can fully re-mix the ore pulp, mixed with the capturing agent and the foaming agent, and the ore pulp in the floatation tank 51, and through the effect of the capturing agent and the foaming agent, the bubbles can be efficiently mineralized to provide a good adsorption mixing effect.
The present embodiment also includes a false bottom 518 and a support column. The false bottom 518 is fixed on the bottom of the floatation tank 51 through the support column, and the outer side end extends to a position close to the inner side of the vertical plate.
In the present embodiment, the scraper mechanism includes a rotating shaft support 52, scraper rotating shafts 514 and scrapers 513. The rotating shaft support 52 is arranged at the upper end of the floatation tank 51. The scraper rotating shafts 514 are arranged on the rotating shaft support 52. One end of each scraper rotating shaft 514 is fixedly connected with an outer driving motor output end 515. A plurality of scrapers 513 are uniformly distributed on each scraper rotating shaft 514. The scrapers 513 are located above the finished ore concentration area.
In the present embodiment, after being thrown out from the outer edge of blades of the stirring impeller 5343, the floatation mineralized foams float upwardly to a liquid surface above a floatation area and are fully accumulated at the upper ends of the guide partition plates 516. The secondarily concentrated finished ore foams are scraped off the floatation tank 51 by the scrapers 513, while the concentrated residual fine silt with high ash content and the finished ore foams that are not scraped off and separated from the bubbles deposit downwardly to the finished ore concentration area 517. The mineralized foams that are settled in the finished ore concentration areas 517 at both sides sink to the lower ends of the guide partition plates 516 and pass by the guide partition plates 516 respectively to reach the floatation area so as to realize the re-floatation. The ore pulp settled to the bottom of the floatation tank 51 enters the next floatation tank via the ore pulp inlet 511 to perform the re-floatation.
Specifically, the ore pulp enters the floatation tank 51 via the ore pulp inlet 511 through a pump body and is discharged through the ore pulp outlet 512. The circulating pump 520 pumps the ore pulp extracted from an ore pulp circulating discharging opening 519 into the ore pulp circulating feeding pipes 5317, and the emulsified capturing agent in the capturing agent adding pipes 5314 is injected at the same time, so that the ore pulp is fully mixed and interacts with the capturing agent first to change the surface hydrophobicity of the minerals and is sprayed out via the inner nozzle 5312b. Then under the injection effect, the atomized foaming agent in the atomized chemical adding pipes 5315 is sucked and is fully mixed with the modified ore pulp in the outer nozzle 5312a and then is sprayed out of the annular jet nozzles 5312 at high speed to impact the driving impeller 5314 to rotate, thereby driving the rotary connecting rod 5342 to rotate. The ore pulp thrown by the rotation of the driving impeller 5314 is re-mixed under the rotating and stirring effect of the centrifugal stirring sieve 5344, so that the three phases, i.e. gas, liquid and solid are fully mixed and dispersed and pass through the centrifugal stirring sieve 5344 to be discharged into the guide cylinder 532 via the discharging opening 5313 and are then mixed and stirred by the stirring impeller 5343. Finally after being thrown out from the edge of the stirring impeller 5343, the stirred floatation mineralized foams float upwardly to the liquid surface above the floatation area and are fully accumulated at the upper ends of guide partition plates 516 to be scraped off the flotation tank 51 by the scrapers 513. The mineralized foams that are not scraped deposit down to the finished ore concentration area 517, are settled below the guide partition plates 516 and pass by the guide partition plates 516 to return to the floatation mineralization area to participate in the floatation again. The circulating ore pulp is re-pumped by the circulating pump 520 into the ore pulp circulating feeding pipes 5317 via the ore pulp circulating discharging opening 519 to realize the circulating floatation.

The guide hood baseplate 164 is located below the atomizing hood baseplate 156, an atomizing outlet passage is formed between an outer side section of the guide hood baseplate and the conical guide hood 133, and the atomizing outlet 154 is communicated with the airflow passage hole and the atomizing outlet passage.
The outer side end of the guide hood baseplate 164 extends obliquely towards the lateral top and forms a passage with the upper horn disc 163. The distributing shear flow channels 161 are arranged in the passage. The lower horn disc 1632 is integrally connected with an extension end at the outer side of the guide hood baseplate 164 and forms a sudden expansion atomizing cavity 162 with the upper horn disc 1631.
More specifically, in the present embodiment, the shear driving layers 144 are formed among the laminar flow guide discs 142. The spray distributing pipes 131 distribute the sprayed liquid, i.e. the surface-active agent-foaming agent, then the sprayed surface active agent-foaming agent drives the laminar flow guide discs 142, so that a dispersion atomizing effect can be played again.
By using the interaction of the atomized foaming agent and the bubbles, the surface active agent- foaming agent is pre-atomized and then contacts the air, so that the broken bubbles are in an atmosphere inhibiting the conglomeration, and the stability of a micro-bubble system is kept. Meanwhile, through the shearing and turbulent mixing, the micro-bubble system is more balanced to provide a sufficient contact opportunity for the efficient mineralization of the surface active agent-foaming agent, thereby greatly improving the mineralization efficiency, and improving the floatation effect.
In the present embodiment, the close cover 1 includes a bearing sleeve 12 and a sealing cover 11. The bearing sleeve 12 is fastened to the upper end of the atomizing cylinder 13 through a bolt. The sealing cover 11 is fastened to the upper end of the bearing sleeve 12 through a bolt.

The lower end of the bearing is clamped and positioned by a top ring 121a formed by inwardly extending the lower end of the inner wall of the bearing sleeve 12.
By adopting the above technical solution, the two bearings are clamped and embedded in the bearing sleeve 12 and are limited by the convex ring 141a and the top ring 121a to avoid moving when the whole body rotates, thereby ensuring the rotating stability of the rotating shaft
141.
In the present embodiment, the spray distributing pipes 131 are divided into multiple groups.
Longitudinal sections of a plurality of spray distributing pipes 131 in each group are distributed on the wall of the atomizing cylinder 13 in a fan shape and are gradually increased towards the shear driving layers 144.
In the present embodiment, the outer edge of each laminar flow guide disc 142 is set as a conical shape, so that the spray distributing pipes 131 can more smoothly distribute the surface- active agent-foaming agent into the laminar flow guide discs 142.
More specifically, the laminar flow guide discs 142 are made of a high-strength alloy steel plate, and the surface roughness RZ is less than or equal to 1.6.
More specifically, a height H of each shear driving layer 144 is greater than or equal to 0.3mm and less than or equal to 1mm.
By adopting the above technical solution, in the present embodiment, the surface active agentfoaming agent is conveyed by a chemical pump to spray distributing pipes 131, then sprayed out by the spray distributing pipes 131 and distributed into the shear driving layers along a tangent direction of the laminar flow guide discs 142. By utilizing a viscous force effect of boundary layers of the shear driving layers 144, the energy carried by the pumped foaming agent is fully used to drive the laminar flow guide discs 142 to rotate at high speed. Meanwhile, with the transfer of the energy carried by the foaming agent, a jet speed of the foaming agent is reduced gradually, the centrifugal force of the foaming agent is reduced, the foaming agent is gathered to the centre, and the radial speed of the foaming agent is reduced until the foaming agent is gathered to the drainage holes 145. In the present embodiment, through the distribution of the spray distributing pipes 131 and the separation of the laminar flow guide discs 142, the surface- active agent-foaming agent is fully dispersed, thereby obtaining better performance.
In the present embodiment, the atomizing floatation device also includes an atomizing turn plate 15. The atomizing turn plate 15 includes a discharging cylinder 151, a conical atomizing hood 152 and an atomizing hood baseplate 156. The discharging cylinder 151 is fixed at the lower end of the laminar flow guide disc 142 on the lowermost end in the atomizing cylinder 13 and is correspondingly located at the outer side of drainage hole 145.
The conical atomizing hood 152 is located below the conical guide hood 133. An airflow passage hole is reserved between the outer side end of the conical atomizing hood 152 and a position close to the end portion of the conical guide hood 133. The conical guide hood 133 is provided with an air hole corresponding to the conical atomizing hood 152, and the air hole is connected and communicated with the driving air pipe 132. The outer side end of the atomizing hood baseplate 156 corresponds to the outer side end of the conical atomizing hood 152, and an atomizing outlet 154 is formed between the two outer side ends.

More specifically, a residual liquid recycling and atomizing passage 155 is formed between the outer wall surface of the atomizing turn plate 15 and the inner wall surface of a rotating cylinder 13; if the passage is closer to the atomizing outlet 154, the space is smaller.
In the present embodiment, the atomizing turn plate 15 is driven by the laminar flow guide discs 142 to rotate at high speed. The surface active agent-foaming agent is gathered into the conical atomizing hood 152, is rapidly allocated into the distributing shear flow channels a153 under the high-speed rotation centrifugal effect of the conical atomizing hood 152, is sheared and atomized rapidly along the distributing shear flow channels a153, and is sprayed out along the atomizing outlet 154. The high-speed atomized gas forms a negative pressure area on the periphery of the atomizing outlet 154 to inject the air in the driving air pipe 132 and to violently mix the air and the atomized foaming agent, so that a uniform and stable micro-bubble group can be more easily formed, thereby facilitating the floatation.
More specifically, the secondary atomizing shear mechanism 16 is integrally of a disc shape. The distributing shear flow channels b161 are circumferentially distributed. The sudden expansion atomizing cavity 162 is provided with a plurality of converging atomized chemical adding pipes
5315. The atomized chemical adding pipes 5315 are used to add the atomized and foamed surface-active agent-foaming agent into the ore pulp floatation device.
In the present embodiment, after passing by the atomizing outlet 154, through the re-shear mixing and cutting of the distributing shear flow channels b161, the air can be fully cut into micro bubbles. Through the sudden expansion atomizing cavity 162, the large-granularity bubbles are broken again by the negative pressure, and finally, under the full contact and interaction of the foaming agent and the air, the uniform and stable micro-bubble group is formed, thereby facilitating the floatation.
In the present embodiment, the shear driving layers 144 are formed among the laminar flow guide discs 142. The spray distributing pipes 131 distribute the sprayed liquid, i.e., the surface- active agent-foaming agent, and then the sprayed surface-active agent-foaming agent drives the laminar flow guide discs 142, so that a dispersion atomizing effect can be played again. By using the interaction of the atomized foaming agent and the bubbles, the surface active agent-foaming agent is pre-atomized and then contacts the air, so that the broken bubbles are in an atmosphere inhibiting the conglomeration, and the stability of a micro-bubble system is kept. Meanwhile, through the shearing and turbulent mixing, the micro-bubble system is more balanced to provide a sufficient contact opportunity for the efficient mineralization of the surface-active agent-foaming agent, thereby greatly improving the mineralization efficiency, and improving the floatation effect.
As shown in Fig. 1 and Fig. 4, in another embodiment, a spray atomizing device includes the above two-linked-wheel spray stirring mechanism, also includes a spray atomizing apparatus, and also includes a supercharging mixing conveying mechanism 17. The supercharging mixing conveying mechanism 17 is used for strengthening the bubble atomizing effect of the surface- active agent-foaming agent or for emulsifying the capturing agent.
The supercharging mixing conveying mechanism 17 includes a mixing cavity 171, an axial- flow mixing speedup impeller 172, a primary suction pipe 173, conveying pipes 174, secondary suction pipes 175, a sudden expansion mixing cavity 176, an allocation cavity 177 and distributing outlets 178. An upper portion of the mixing cavity 171 is set as a cylindrical shape, and the lower end is of a cylindrical shape. The atomizing outlet 154 is communicated with the mixing cavity 171, and the primary suction pipe 173 is communicated with the upper end of the mixing cavity
171. The axial-flow mixing speedup impeller 172 consists of axial-flow blades 172a and a centre shaft 172b, and the axial-flow blades 172a are uniformly welded on the side wall of the centre shaft 172b. The axial-flow mixing speedup impeller 172 is welded on the lower surface of the atomizing hood baseplate 156 through the centre shaft 172b. A speedup outlet is formed at the lower end of the mixing cavity 171, and the lower end of the speedup outlet is communicated with the conveying pipes 174. The secondary suction pipes 175 are uniformly distributed on the outer walls of the conveying pipes 174 and communicated with inner cavities of the conveying pipes
174. The upper end of the sudden expansion mixing cavity 176 is communicated with a lower port of the conveying pipe 174. The sudden expansion mixing cavity 176 is of a rhombic shape. The allocation cavity 177 is arranged at a lower port of the sudden expansion mixing cavity 176. The bottom of the allocation cavity 177 is provided with a plurality of distributing outlets 178. The plurality of distributing outlets 178 are connected and communicated with the atomized chemical adding pipe 5315.
In the present embodiment, after passing through the atomizing outlet 154, the atomized gas can also be gathered into the mixing cavity 171. The high-speed rotation of the atomizing turn plate 15 drives the axial-flow mixing speedup impeller 172 to rotate at a high speed. The rotation of the axial-flow mixing speedup impeller drives the atomized gas to speed up to flow towards the speedup outlet along the axial direction of the centre shaft, and also drives the primary suction pipe 173 to inject the air, and the injected air is mixed with the atomized gas to speed up to flow towards the speedup outlet. The mixed atomized gas flows into the sudden expansion mixing cavity 176 at a high speed through the conveying pipes 179 to drive the secondary suction pipes 175 to inject the gas while being simultaneously mixed and atomized again in the sudden expansion mixing cavity 176, forming the uniform and stable micro-bubble group, thereby preventing the re-emulsification of the atomized gas. The mixed atomized gas enters the atomized chemical adding pipe through the distributing outlets 178 on the lower end of the allocation cavity 177 to participate in the floatation. In the present embodiment, due to the supercharging mixing and conveying of the axial-flow mixing speedup impeller 172 and the injection effect of the secondary suction pipes 175, the atomized gas can be fully mixed and can be efficiently mixed with the ore pulp at a high speed, thereby facilitating the floatation.
Compared with the existing floatation process that the final energy of chemical and pulp conveying is all converted into internal energy consumed in a pulp mixing device and the floatation tank, the present embodiment makes full use of the jet energy of the ore pulp sent by the circulating pump 520 and used for spray of the annular jet nozzle 5312 to drive the spray atomizing apparatus and to drive the pre-treatment stirring mechanism for pulp mixing pre-treatment, which realizes the effective utilization of the energy and reduces the energy consumption. The structural design and the working process give full consideration to the pre-treatment effect of the capturing agent on the ore pulp and the effect of the atomized foaming agent on generating the bubbles, and enable the capturing agent to pre-react with the ore pulp to change the surface hydrophobicity of the minerals, thereby providing a good adsorption interface for the efficient mineralization with the bubbles. Meanwhile, the foaming agent is pre-atomized and then contacts the air, so that the broken bubbles are in the atmosphere inhibiting the conglomeration, thereby keeping the stability of the micro-bubble system. Through multi-time shearing and turbulent mixing, the micro-bubble system is more balanced to provide a sufficient contact opportunity for the efficient mineralization of the bubbles, thereby greatly improving the mineralization efficiency, and improving the floatation effect.
