With the continuous development of phosphate resources, high-grade and easily selected phosphate ores are gradually decreasing, and the development and utilization of fine particle phosphate resources have become increasingly important. Fine particle phosphate ore has different physical and chemical properties from coarse particle phosphate ore due to its small particle size. Traditional beneficiation methods are difficult to efficiently recover, which poses a challenge to beneficiation technology and promotes the continuous innovation of related technologies to achieve effective separation and enrichment of fine particle phosphate ore.

[0003] The existing fine particle phosphorus flotation column flotation equipment has insufficient contact between bubbles and fine particle phosphorus, resulting in low overall recovery rate. The outlet of the traditional bubble generator is easily clogged by particles in the outlet, increasing the risk of clogging. Therefore, improvement and optimization are needed. SUMMARY

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a flotation column flotation equipment for fine particle phosphorus, comprising a flotation column, an annular support is fixedly installed below the inner wall of the flotation column, a first communication pipe is fixedly installed on the inner side of the annular support and arranged in a circumferential array, one end of the first communication pipe is in communication with the annular support, the other end of the first communication pipe is fixedly installed with a collection adapter and the first communication pipe extends into the collection adapter, a gas-tight cover is fixedly installed at the bottom of the collection adapter, a first bubble outlet is formed on the outer surface of the first communication pipe and arranged in a linear array, a second communication pipe is fixedly connected to the outer surface of the collection adapter and one end of the second communication pipe extends into the collection adapter, a bubble generator is fixedly installed on the right side of the outer surface of the flotation column and the other end of the second communication pipe extends into the bubble generator through the annular support and the flotation column, a second bubble outlet is formed on the bottom side of the annular support and arranged in a circumferential array, and a cyclone mechanism is fixedly installed on the right side of the outer surface of the flotation column.

[0006] As a preferred technical scheme of the utility model, the cyclone mechanism includes the support frame fixedly installed on the right side of the outer surface of the flotation column, the cyclone tank fixedly installed on the right side of the support frame, the bracket fixedly installed on the bottom of the cyclone tank, the motor fixedly installed on the inner side of the bracket and the output shaft of the motor extending into the cyclone tank, the rotary rod fixedly connected with the end of the output shaft of the cyclone tank, the cyclone device fixedly sleeved with the outer surface of the rotary rod, the cyclone tank and the flotation column being communicated with each other through the third communicating pipe, one end of the third communicating pipe extending into the cyclone tank and the rotary rod and the cyclone device extending into the inner side of the third communicating pipe, and the connecting pipe fixedly installed on the right side of the outer surface of the cyclone tank.

[0007] As a preferred technical scheme of the utility model, the bottom of the flotation column is fixedly installed with the discharge pipe, the valve is threadedly connected in the discharge pipe, and the rotary handle is rotatably installed on the bottom of the valve.

[0008] As a preferred technical scheme of the utility model, the right side of the flotation column is fixedly installed with the discharge groove, and the discharge groove is L-shaped and extends into the inner side of the flotation column.

[0012] Compared with the prior art, the utility model has the beneficial effects as follows:

[0013] 1. In this invention, bubbles inside the collection and transfer device slowly rise from the bottom of the flotation column through the first bubble outlet at the bottom of the first connecting pipe and the second bubble outlet at the bottom of the annular support. When the bubbles come into contact with the fine phosphorus particles processed by the cyclone mechanism during their ascent, the fine phosphorus particles adhere to the bubbles and rise together with the bubbles to the top of the flotation column, forming a foam layer. This foam layer contains fine phosphorus particles, while other mineral particles that do not adhere to the bubbles sink to the bottom of the flotation column. Compared with traditional devices, this device moves the bubbles from bottom to top, forming a countercurrent contact with the slurry fed from the top, thus improving the overall recovery rate. Compared with the traditional bubble generator outlets located in other positions, the bottom-to-top outlet design reduces the possibility of fine phosphorus particles settling and accumulating in the bubble outlet, thereby reducing the risk of blockage and improving the stability and controllability of the flotation process.

[0014] 2. This utility model uses the output shaft of a motor to drive a rotating rod to start rotating. When the rotating rod starts rotating, it will drive the cyclone device to start rotating. Since the cyclone device extends to the inside of the third connecting pipe, the fine phosphate rock particles will be separated into coarse and fine particles by centrifugal force and quickly transported to the inside of the flotation column for flotation through the third connecting pipe. Compared with traditional devices, this device can lay the foundation for efficient flotation of the subsequent flotation column, avoid a large number of coarse particles entering the flotation column and interfering with the flotation process of bubbles and fine phosphate in the flotation column, and make the particle size entering the flotation column more uniform and more in line with the flotation conditions.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5 As shown, this utility model provides a flotation column flotation device for fine phosphorus, including a flotation column 1. An annular support 2 is fixedly installed on the lower inner wall of the flotation column 1. A first connecting pipe 4 is fixedly installed on the inner side of the annular support 2, and the first connecting pipe 4 is arranged in a circumferential array. One end of the first connecting pipe 4 is fixedly connected to the annular support 2, and the other end of the first connecting pipe 4 is fixedly installed with a collecting and connecting device 6, and the first connecting pipe 4 extends into the collecting and connecting device 6. An airtight cover 7 is fixedly installed at the bottom of the collecting and connecting device 6. A first bubble outlet 5 is opened on the bottom side of the outer surface of the first connecting pipe 4 and is arranged in a linear array. A second connecting pipe 9 is fixedly connected to the outer surface of the collecting and connecting device 6, and one end of the second connecting pipe 9 extends into the collecting and connecting device 6. A bubble device 3 is fixedly installed on the right side of the outer surface of the flotation column 1, and the other end of the second connecting pipe 9 passes through the annular support 2 and the flotation column 1 and extends into the bubble device 3. A second bubble outlet 8 is opened on the bottom side of the annular support 2 and is arranged in a circumferential array. A swirling mechanism is fixedly installed on the right side of the outer surface of the flotation column 1.

[0023] When the classified fine phosphorus particles are transported into the flotation column 1 through the cyclone mechanism, the bubble device 3 is activated in advance. When the bubble device 3 is activated, the generated bubbles will be transported into the collection and transfer device 6 through the second connecting pipe 9. Then, the collection and transfer device 6 is connected to the first connecting pipe 4, which is arranged in a circumferential array, and the first connecting pipe 4 is also connected to the annular support 2. This will cause the bubbles inside the collection and transfer device 6 to slowly rise from the bottom of the flotation column 1 through the first bubble outlet 5 at the bottom of the first connecting pipe 4 and the second bubble outlet 8 at the bottom of the annular support 2. When the bubbles rise and come into contact with the fine phosphorus particles processed by the cyclone mechanism, the fine phosphorus particles will adhere to the bubbles and rise to the top of the flotation column 1 together with the bubbles, forming a foam layer. This part of the foam layer contains fine phosphorus particles, while other mineral particles that are not attached to the bubbles sink to the bottom of the flotation column 1.

[0024] The bubbles inside the collection switching device 6 slowly rise upwards from the bottom of the first bubble discharge port 5 opened at the bottom of the first communication pipe 4 and the second bubble discharge port 8 opened at the bottom of the annular support 2, and when the bubbles rise and contact the fine-grained phosphorus treated by the cyclone mechanism, the fine-grained phosphorus will adhere to the bubbles and rise to the top of the flotation column 1 together to form a foam layer, and the fine-grained phosphorus in this part of the foam layer, and other mineral particles that do not adhere to the bubbles sink to the bottom of the flotation column 1. Compared with the traditional device, the bubbles move from bottom to top, and form countercurrent contact with the ore pulp fed from the upper part, which improves the comprehensive recovery rate. Compared with the traditional bubble generating device, the discharge port design from bottom to top reduces the possibility of fine-grained phosphorus particles settling and accumulating in the bubble discharge port, thereby reducing the risk of blockage and improving the stability and controllability of the flotation process.

[0025] The cyclone mechanism comprises a support frame 10 fixedly installed on the right side of the outer surface of the flotation column 1, a cyclone tank 11 fixedly installed on the right side of the support frame 10, a support 12 fixedly installed at the bottom of the cyclone tank 11, a motor 13 fixedly installed on the inner side of the support 12, and the output shaft of the motor 13 extends into the inside of the cyclone tank 11. A rotating rod 14 is fixedly connected to the end of the output shaft of the cyclone tank 11, and a cyclone device 15 is fixedly sleeved on the outer surface of the rotating rod 14. The cyclone tank 11 and the flotation column 1 are connected to each other through a third communication pipe 16. One end of the third communication pipe 16 extends into the inside of the cyclone tank 11, and the rotating rod 14 and the cyclone device 15 extend into the inside of the third communication pipe 16. A connecting pipe 17 is fixedly installed on the right side of the outer surface of the cyclone tank 11.

[0026] When the fine-grained phosphate ore particles treated by the inclined plate desliming and the reagent are transported into the inside of the cyclone tank 11 through the connecting pipe 17, the motor 13 is started at the same time. At this time, the output shaft of the motor 13 will drive the rotating rod 14 to start rotating, which will drive the cyclone device 15 to start rotating. Since the cyclone device 15 extends into the inside of the third communication pipe 16, the fine-grained phosphate ore particles will be separated by centrifugal force, and quickly transported into the inside of the flotation column 1 through the third communication pipe 16 for flotation.

[0027] The output shaft of the motor 13 will drive the rotating rod 14 to start rotating, which will drive the cyclone device 15 to start rotating. Since the cyclone device 15 extends into the inside of the third communication pipe 16, the fine-grained phosphate ore particles will be separated by centrifugal force, and quickly transported into the inside of the flotation column 1 through the third communication pipe 16 for flotation. Compared with the traditional device, the device can lay a foundation for efficient flotation of the subsequent flotation column 1, avoid a large number of coarse particles from entering the flotation column 1 to interfere with the flotation process of the bubbles and the fine-grained phosphorus in the flotation column 1, and make the particle size entering the flotation column 1 more uniform and more in line with the flotation conditions.

[0028] The bottom of the flotation column 1 is fixedly provided with a discharge pipe 19, the discharge pipe 19 is internally threadedly connected with a valve 20, and the bottom of the valve 20 is rotatably provided with a rotating handle 21.

[0029] The rotating handle 21 is rotated by external force to drive the valve 20 to rotate, and since the valve 20 is internally threadedly connected with the discharge pipe 19, the valve 20 can be smoothly separated from the discharge pipe 19 when the valve 20 rotates, so that other mineral particles at the bottom can be smoothly discharged out of the flotation column 1.

[0030] The right side of the flotation column 1 is fixedly provided with a discharge chute 18, and the discharge chute 18 is in L-shaped and extends to the inside of the flotation column 1 at one end.

[0031] The discharge chute 18 is in L-shaped and extends to the inside of the flotation column 1 at one end, so that fine-grained phosphorus rising to the top of the flotation column 1 along with the bubbles can be effectively discharged into the collecting device through the discharge chute 18.

[0032] The right side of the flotation column 1 is fixedly provided with a support frame 10, and the support frame 10 has one group and the group has two support frames 10 fixedly connected with the cyclone tank 11.

[0033] The support frame 10 has one group and the group has two support frames 10 fixedly connected with the cyclone tank 11, so that the running stability of the whole device can be effectively improved and the failure rate can be reduced.

[0034] The right outer surface of the cyclone tank 11 is fixedly provided with a connecting pipe 17, and the connecting pipe 17 extends to the inside of the cyclone tank 11 and does not contact the cyclone device 15.

[0035] The connecting pipe 17 extends to the inside of the cyclone tank 11 and does not contact the cyclone device 15, so that fine-grained phosphate particles treated by the inclined plate desliming and the reagent can be effectively transported to the inside of the cyclone tank 11 and will not affect the cyclone device 15.

[0036] The bottom of the collection switching device 6 is fixedly provided with an airtight cover 7, and the airtight cover 7 is circularly and tightly fixedly connected with the collection switching device 6.

[0037] The airtight cover 7 is circularly and tightly fixedly connected with the collection switching device 6, so that the airtightness of the collection switching device 6 can be effectively improved, and the lack of bubbles of the device caused by insufficient airtightness can be avoided.

[0038] The working principle and use process of the utility model are as follows:

[0039] When the fine particles of phosphorus after classification are transported into the inside of the flotation column 1 through the cyclone mechanism, the bubble device 3 is started in advance, when the bubble device 3 is started, the generated bubbles will be transported into the inside of the collection switching device 6 through the second communication pipe 9, then the collection switching device 6 is connected with the first communication pipe 4 in the circumferential array and the first communication pipe 4 is communicated with the annular support 2, the bubbles in the inside of the collection switching device 6 will slowly rise from the bottom of the flotation column 1 upwards along with the first bubble discharge port 5 opened at the bottom of the first communication pipe 4 and the second bubble discharge port 8 opened at the bottom of the annular support 2, when the bubbles rise and contact with the fine particles of phosphorus treated by the cyclone mechanism, the fine particles of phosphorus will be attached to the bubbles, rise to the top of the flotation column 1 together with the bubbles, form a foam layer, the fine particles of phosphorus in the foam layer, and other mineral particles not attached to the bubbles will sink to the bottom of the flotation column 1.

[0040] When the fine particles of phosphorus ore treated by the inclined plate desliming and the reagent are transported into the inside of the cyclone tank 11 through the connecting pipe 17, the motor 13 is started at the same time, at this time the output shaft of the motor 13 will drive the rotating rod 14 to start rotating, when the rotating rod 14 starts rotating, the cyclone device 15 will start rotating, because the cyclone device 15 extends to the inside of the third communication pipe 16, the fine particles of phosphorus ore will be separated by the centrifugal force, and transported into the inside of the flotation column 1 through the third communication pipe 16 for flotation.
