Description

Technical Field

[0001] The present invention relates to the technical field of flotation equipment, in particular to a bubble pushing device of a flotation machine. Background Art

[0002] The bubble pusher is a key component of the flotation machine. It is usually located at the top of the flotation cell, close to the foam overflow area. It is mainly used to regulate and control the mineralized foam layer generated during the flotation process to ensure that the foam flows stably and evenly and is discharged efficiently.

In the process of pushing the foam, the slurry may be driven to flow, causing part of the slurry to overflow and mix into the concentrate, affecting the flotation effect. When the foam layer is thin, in the process of pushing the foam, the air flow can easily blow away the foam layer, causing the liquid surface to flip, destroying the foam layer structure, reducing the mineral recovery efficiency, and even affecting the quality of the floated concentrate.

[0026] like Figures 6 to 16 As shown, the second connecting frame 34 is fixedly connected to the second connecting port 333 on the third connecting pipe 33 by bolts, and a connecting frame 341 is provided on the second connecting frame 34. The connecting frame 341 is sleeved on the outside of the bubble pushing plate 35, and a cavity 342 is opened in the connecting frame 341. An air outlet 343 is opened on the inner side of the connecting frame 341. The air outlet 343 is tilted on the inner side of the connecting frame 341 to connect the cavity 342 with the outside. There are multiple air outlets 343, which are evenly distributed on the connecting frame 34. 1, a connecting hole 344 is provided on the second connecting frame 34, an air flow channel 345 is provided in the second connecting frame 34, the air flow channel 345 is communicated with the cavity 342, a slide groove 346 is provided inside the air flow channel 345, a weight block 347 is provided inside the air flow channel 345, a slide bar 348 and a sealing gasket 349 are provided on the weight block 347, the slide bar 348 is provided inside the slide groove 346, and the weight block 347 is slidably connected to the inside of the air flow channel 345 through the slide bar 348.

[0027] like Figure 6 、 Figure 7 、 Figure 12 and Figure 17 As shown, a floating strip 351 is provided on one side of the bubble pushing plate 35, and a sliding rod 352 is provided on the bubble pushing plate 35. The sliding rod 352 is set in the connecting hole 344. The bubble pushing plate 35 is slidably connected to the second connecting frame 34 through the sliding rod 352, and a limiting block 353 is provided at one end of the sliding rod 352 away from the bubble pushing plate 35.

[0028] The working process is as follows: S1, when in use, adding slurry to the flotation cell 1 and starting the bubble generating device 2, so that ore-containing foam appears in the flotation cell 1; S2. Then, the second driving member 31 is started. The second driving member 31 drives the second pulley 331 to rotate via the second transmission belt 32. The second pulley 331 drives the second connecting frame 34 via the third connecting tube 33. The second connecting frame 34 drives the bubble pushing plate 35 to rotate around the axis of the third connecting tube 33. S3. At the same time, the gas output device 4 is activated, and the gas enters the third connecting pipe 33 through the one-way valve 5 and the rotary joint 6, then enters the air flow channel 345 from the second connecting port 333, enters the cavity 342 from the air flow channel 345, and finally blows out from the air outlet 343; S4: When the second connecting frame 34 drives the bubble pushing plate 35 to push the foam downward, the weight block 347 moves toward the connecting frame 341 in the air flow channel 345 due to gravity, and the sealing gasket 349 blocks the connection between the air flow channel 345 and the cavity 342, thereby preventing the air flow from blowing away the foam layer, causing the liquid surface to overflow, causing the foam layer structure to be destroyed, and reducing the mineral recovery efficiency, thereby avoiding affecting the quality of the flotation concentrate; S5. The pusher plate 35 is always kept above the slurry surface due to the buoyancy of the float bars 351, so that the pusher plate 35 does not drive the slurry to flow during the process of pushing the foam, thereby preventing the slurry from overflowing and mixing with the concentrate, thereby ensuring the flotation effect; S6. When the second connecting frame 34 rotates upward, the weight block 347 moves toward the third connecting pipe 33 due to gravity, causing the sealing gasket 349 to leave the connection between the air flow channel 345 and the cavity 342. The air flows from the air flow channel 345 into the cavity 342 and is then blown out along the inclined air outlet 343. S7. While the air flow is blowing out, due to gravity, the bubble pushing plate 35 moves in the connecting frame 341 toward the third connecting tube 33. During the movement of the bubble pushing plate 35, the air flow blown out from the air outlet 343 cleans away the residual mineral-containing foam attached to the bubble pushing plate 35, thereby preventing the mineral-containing foam attached to the bubble pushing plate 35 from corroding the bubble pushing plate 35 or affecting the subsequent bubble pushing effect.
