[0002] In the process of graphite tailings processing, the tailings are usually ground into small particles first, and then put into a flotation machine to select the desired mineral. The flotation machines commonly used on the market are not uniform in bubble dispersion during use, resulting in a low extraction rate of the ore pulp. When the equipment discharges, the untreated ore pulp is directly discharged into the treated ore pulp at the top, while the ore pulp is discharged at the bottom. This operation is likely to cause part of the untreated ore pulp to be directly discharged, wasting resources. Therefore, it is necessary to improve. SUMMARY

[0027] The inner cylinder 16 is provided with a spiral groove 17, and a rotating plate 161 is connected to the upper end of the inner cylinder 16 near the opening of the spiral groove 17 by a spring hinge 162.

[0028] The rotating device 21 includes multiple partitions 211 and multiple sliding plates 212; the multiple partitions 211 and multiple sliding plates 212 are spaced apart, and each partition 211 has a groove 215 on its side, and each sliding plate 212 has a slider fixedly connected to its side, which slides in cooperation with the groove 215; each sliding plate 212 has multiple vertical perforations 213 on its upper surface, and each sliding plate 212 has a slope at the lower end of its side surface; the cylinder 23 is fixedly connected to the upper end of the partition 211; the lower end of the partition 211 is in contact with the connecting box 116.

[0029] Each slide plate 212 has an arc surface on both sides with the same curvature as the inner circular surface of the outer cylinder 11, so that the slide plate 212 can fit completely against the inner wall of the outer cylinder 11.

[0030] The vertical pipe 25 includes a pipe body 251, a vent 252 and a slide 253; the pipe body 251 is fixedly connected to the upper end of the partition 211, the side of the pipe body 251 is provided with a plurality of vents 252, and the side of the pipe body 251 is also provided with a vertical slide 253.

The circular plate 261 is also provided with a vertical through hole 262 penetrating the circular plate 261. The flap 265 is hinged to the lower end of the through hole 262.

[0032] The limiting block I263 on the side of the circular plate 261 is located above the inner cylinder 16 and contacts the rotating plate 161 as the circular plate 261 rotates.

[0033] The axis of the motor 110 does not coincide with the axis of the gear 27, so that the arc rod 112 and the circular plate 261 rotate at a different speed, which makes it easier for the arc rod 112 to push the foam on the circular plate 261 into the annular groove 18.

[0034] A purification method for a spherical graphite tailings purification device, the purification method comprising the following steps:

[0035] Step 1: Pour slurry into the outer cylinder 11, start the motor 110 in the forward direction, and start the air pump 114;

[0036] Step 2: After waiting for a period of time, start motor 110 in reverse and open valve I13 to make motor 110 drive circular plate 261 to move downward and discharge slurry. At the same time, add new slurry to the upper end of outer cylinder 11 to the upper end of circular plate 261.

[0037] Step 3: After the slurry at the lower end of the circular plate 261 is discharged, start the motor 110 again in the forward direction;

[0038] Step 4: Repeat the above steps to continuously process the slurry without shutting down the machine.

[0039] The working principle of this invention is as follows: When using this device, slurry is introduced into the outer cylinder 11, the motor 110 is started in the forward direction, and the air pump 114 is started.

[0040] Motor 110 rotates in the forward direction, driving turntable 111 and connecting cylinder 113 to rotate, which in turn drives arc rod 112 to rotate in the forward direction. Simultaneously, the rotation of connecting cylinder 113 also drives gear 27 to rotate in the forward direction through its internal toothed grooves. Gear 27 drives vertical tube 25 to rotate, and vertical tube 25 drives circular plate 261 to rotate in the forward direction through slide rail 253. When circular plate 261 rotates in the forward direction, the limiting block I 263 on the outer side of circular plate 261... Figure 5 The rotating plate 161 shown has the same inclination direction. Therefore, when the limiting block I 263 contacts the rotating plate 161, the rotating plate 161 rotates around the spring hinge 162 to a horizontal state. When the limiting block I 263 disengages from the rotating plate 161, the rotating plate 161 springs back to its original position under the elastic force of the spring hinge 162. At the same time, the rotation of the vertical tube 25 also drives the partition plate 211 to rotate, and the partition plate 211 drives the slide plate 212 to rotate. Simultaneously, the partition plate 211 also drives the cylinder 23 and the annular plate 22 to rotate. The lower end face of the annular plate 22 is always in contact with the slide plate. The upper end face of plate 212 is in contact with the lower end of the annular plate 22, and the lower ends of the partition plate 211 and the slide plate 212 are also equipped with sealing gaskets. When the air pump 114 outputs gas into the connecting box 116, the gas is discharged from the air hole at the upper end of the connecting box 116. Some of the gas directly enters the interior of the outer cylinder 11 through the perforation 213 on the slide plate 212. After contacting the slurry, it carries some of the substances in the slurry upward to the upper part of the liquid surface. The other part of the gas passes through the gap between the slide plate 212 and two adjacent partition plates 211. Figure 6 As shown in the image, the slide plate 212 moves to the space between the annular plate 22 and the cylinder 23, and enters the interior of the vertical pipe 25 through the connecting pipe 24. It is then discharged into the slurry through the vent 252 on the side of the vertical pipe 25. A portion of the gas also moves to the enclosed space between the inclined surface of the slide plate 212, two adjacent partitions 211, and the inner wall of the outer cylinder 11. Figure 6As shown on the left side of the skateboard 212, it impacts the inclined surface of the side of the skateboard 212. Due to the continuous inflow of gas into the enclosed space between the inclined surface, the two adjacent partitions 211, and the inner wall of the outer cylinder 11, the impact force it receives is greater than that of the skateboard 212 on the right side and the open space formed by the two adjacent partitions 211. Under the action of the impact force, the skateboard 212 is pushed towards... Figure 6 The right-side slide shown makes Figure 6 The right side of the slide plate 212 forms a closed space consisting of an inclined surface, two adjacent partitions 211, and the inner wall of the outer cylinder 11. After being impacted, it moves to the left. This pushes the slide plate 212 to move left and right repeatedly. While the rotating device 21 rotates with the vertical tube 25, the slide plate 212 slides left and right, so that the position of the perforation 213 of the injected gas changes continuously at the bottom of the outer cylinder 11. This ensures that the bubbles can be dispersed more evenly in the outer cylinder 11, thus ensuring a better slurry treatment effect.

[0041] After the bubbles move to the upper part of the slurry surface, they continuously converge towards the through hole 262 on the circular plate 261 and are exposed at the upper end of the circular plate 261. The arc rod 112 rotates relative to the circular plate 261, causing the arc rod 112 to push the foam exposed at the upper end of the circular plate 261 into the annular groove 18 to complete the collection.

[0042] When slurry needs to be discharged, valve I13 is opened, and motor 110 is started in reverse. Motor 110 drives circular plate 261 to rotate in the opposite direction. When circular plate 261 drives limit block I263 to rotate in the opposite direction and contact rotating plate 161, rotating plate 161 cannot rotate away from inner cylinder 16 under the restriction of spring hinge 162. This causes limit block I263 to move downward along the inclined direction of rotating plate 161 and eventually move into spiral groove 17. Circular plate 261 moves downward with spiral groove 17. When circular plate 261 rotates in the opposite direction, flap 265 hinged at the lower end of circular plate 261 is resisted by slurry, causing the free end of flap 265 to rotate into through hole 262, sealing through hole 262. This separates the upper and lower ends of circular plate 261. As circular plate 261 moves downward, it pushes the treated slurry at its lower end through the discharge port. The gas is discharged through pipe I12, and untreated slurry is simultaneously fed into the upper end of circular plate 261. Since the bubble generator 114 is not turned off, gas is continuously injected into the upper end of circular plate 261 through the vent 252 on vertical pipe 25 to treat the untreated slurry, saving time. The gas injected into the lower end of circular plate 261 is discharged along with the slurry through discharge pipe I12. When circular plate 261 moves to the bottom of outer cylinder 11, motor 110 is turned off. Flip plate 265 moves to a vertical position under the action of gravity, disengaging from through hole 262. Then, motor 110 is started in the forward direction. Motor 110 drives circular plate 261 to rotate in the forward direction and moves back to the upper end of inner cylinder 16 through spiral groove 17. When circular plate 261 rotates in the forward direction, flip plate 265 rotates away from through hole 262 due to the resistance of slurry, thereby avoiding the through hole 262 being blocked and affecting foam treatment.

[0043] By repeating the above steps, the slurry can be processed continuously.
