Description

Technical Field

[0001] The invention relates to the technical field of defoaming and stirring equipment, in particular to a defoaming and stirring barrel for flotation and a use method thereof. Background Art

[0002] The defoaming stirring barrel used in flotation is a key equipment in the mineral processing technology used to eliminate flotation foam, promote slurry mixing and ensure efficient and stable flotation process. In the fields of non-ferrous metal beneficiation and coal flotation, if the large amount of foam generated by the flotation operation is not handled in time, it will affect the subsequent processes and reduce the mineral processing recovery rate. The stirring barrel can accurately solve the foam problem and improve the quality and efficiency of mineral processing.

[0003] When defoaming the slurry in the barrel, most methods are to eliminate foam at a fixed liquid level. If the foam is only eliminated at a fixed liquid level, the foam generated below this level cannot be processed in time. The newly generated foam below the liquid level may sink again with the target minerals or be carried away by the slurry flow, making it impossible to effectively recover these target minerals. The corresponding foam will also aggregate when it rises to the liquid surface, causing the concentrate to leave the mixing barrel, thereby reducing the concentrate recovery rate. Summary of the invention

[0008] Furthermore, two L-shaped pulling plates are fixedly installed at the top of the movable circular plate. Triangular plates are respectively slidably installed in the two L-shaped pulling plates. One end of each of the two triangular plates close to each other extends outside the two L-shaped pulling plates.

One end of each of the two strip-shaped plates away from each other extends outside the two L-shaped pulling plates and is respectively slidably connected to the two L-shaped pulling plates.

[0010] Furthermore, an acceleration mechanism is arranged on the movable circular plate. The acceleration mechanism includes an L-shaped ring groove formed on the movable circular plate. A plurality of leakage grooves are formed on the inner wall of the bottom of the L-shaped ring groove. An L-shaped ring hollow block is slidably installed in the leakage groove. A plurality of water inlet grooves are formed on the outer wall of the L-shaped ring hollow block. Two L-shaped long plates are fixedly installed at the top of the movable circular plate. Telescopic springs are respectively fixedly installed on the inner walls of the tops of the two L-shaped long plates.

[0011] Furthermore, a plurality of conical hollow blocks are fixedly installed at the bottom of the movable circular plate. A plurality of water inlet sector grooves are respectively formed in the outer walls of the plurality of conical hollow blocks. Sector plates are respectively hingedly installed in the plurality of water inlet sector grooves. Support rings are respectively fixedly installed on the plurality of conical hollow blocks.

[0012] Furthermore, a method for defoaming and stirring a flotation bucket is as follows: S1: Start the drive motor. The drive motor drives the rotating shaft to rotate. Under the action of the rectangular groove, the rotating shaft drives the circular slide plate to rotate. The circular slide plate drives the fixed rod to rotate. The fixed rod drives the ring to rotate. Under the action of the thread, the ring moves up and down reciprocally in the barrel. Correspondingly, the circular slide plate will also move synchronously. The circular slide plate will drive the circular cylinder to rotate and move up and down reciprocally. At this time, the circular slide plate will drive the circular cylinder to move synchronously. The circular cylinder will drive a plurality of defoaming teeth to rotate and move up and down simultaneously. When the rotating shaft rotates, it will also drive the four-blade impeller to rotate. The four-blade impeller will drive the pulp and defoaming agent in the barrel to rotate and mix. The centrifugal force generated by the rotation of the four-blade impeller will generate a vortex, and move and concentrate the generated bubbles towards the vortex near the rotating shaft. During the rising and falling rotation process of the defoaming teeth, the bubbles on the slurry surface, in the vortex and including in the slurry can be effectively eliminated; S2: When the circular slide plate descends, it will drive the rotating ring to descend. The rotating ring drives the L-shaped plate to descend. Since the L-shaped plate extends into the strip-shaped limit groove, the L-shaped plate will move up and down stably. The L-shaped plate drives the L-shaped transmission plate to descend. The L-shaped transmission plate will contact the triangular plate. The triangular plate will slide into the L-shaped pull plate. After the L-shaped transmission plate passes the triangular plate, the triangular plate will pop out under the elastic force of the limit spring. At this time, when the circular slide plate rises, the corresponding L-shaped transmission plate will drive the triangular plate to rise. The triangular plate will drive the L-shaped pull plate to rise. The L-shaped pull plate drives the movable circular plate to rise. The movable circular plate will lift the pulp above the movable circular plate; S3: When the movable circular plate rises, the movable spring undergoes tensile deformation. When the L-shaped transmission plate drives the triangular plate to rise, the corresponding limit spring will contact the transmission inclined plate. The transmission inclined plate will adjust the angle away from the C-shaped support limit plate. The transmission inclined plate will顶住 the right inner wall of the limit spring. The limit spring will drive the strip-shaped plate to move away from the triangular plate. The strip-shaped plate will drive the triangular plate to move synchronously. When the triangular plate leaves the L-shaped transmission plate, the movable circular plate will quickly descend under the elastic force of the movable spring. At this time, the mineral particles on the movable circular plate will instantly leave the movable circular plate and freely descend in the barrel. During this process, the mineral particles will fully contact the defoaming agent and be fully stirred in cooperation with the centrifugal force of the four-blade impeller; S4: During the descent of the movable circular plate, the liquid at the bottom of the movable circular plate will flow into the L-shaped ring hollow block through the leakage groove. At this time, the L-shaped ring hollow block will move upward under the action of pressure, and the telescopic spring will be compressed and deformed. When several water inlet grooves on the L-shaped ring hollow block leave the L-shaped ring groove, the liquid entering the L-shaped ring hollow block will be discharged from the water inlet groove. Since the flow rate of the water inlet groove is greater than the flow rate of several filter holes, the movable circular plate will descend rapidly. During the descent of the movable circular plate, the liquid flow at the bottom of the movable circular plate will cause the fan-shaped plate to close the water inlet fan-shaped groove. At this time, the descending speed of the movable circular plate will be increased under the conical action of the conical hollow block to avoid the movable circular plate from descending too slowly, so that the mineral particles and the movable circular plate can be synchronously descended.

[0013] The present invention has the following beneficial effects: (1) The present invention provides a defoaming stirring barrel for flotation. When in use, a driving motor is started, and the driving motor drives the rotating shaft to rotate. The rotating shaft drives the circular slide to rotate under the action of the rectangular groove, and the circular slide drives the fixed rod to rotate. The fixed rod drives the circular ring to rotate. The circular ring moves up and down reciprocatingly in the barrel under the action of the thread, and the corresponding circular slide also moves synchronously. The circular slide drives the circular barrel to rotate and reciprocate up and down. At this time, the circular slide drives the circular barrel to move synchronously, and the circular barrel drives a number of defoaming teeth to rotate and move up and down at the same time. When the rotating shaft rotates, it also drives the four-blade paddle to rotate. The four-blade paddle drives the slurry and defoaming agent in the barrel to rotate. The centrifugal force generated by the rotation of the four-blade paddle will generate a vortex, and the generated bubbles will be moved and concentrated near the vortex close to the rotating shaft. During the defoaming teeth's rising and falling rotation process, the bubbles on the slurry surface and in the vortex, including the bubbles in the slurry, can be effectively eliminated, thereby improving the effect of foam elimination, avoiding the foam from concentrating in the vortex and on the liquid surface, resulting in excessive foam overflow and the discharge of concentrate out of the barrel, causing waste, and the concentrate sinking again; (2) The present invention uses a defoaming stirring barrel for flotation. When the circular slide plate descends, the rotating ring is driven to descend, and the rotating ring drives the L-shaped plate to descend. Since the L-shaped plate extends into the strip-shaped limiting groove, the L-shaped plate can move up and down stably. The L-shaped plate drives the L-shaped transmission plate to descend, and the L-shaped transmission plate contacts the triangular plate, and the triangular plate slides into the L-shaped pull plate. After the L-shaped transmission plate passes the triangular plate, the triangular plate pops out under the elastic force of the limiting spring. At this time, when the circular slide plate rises, the corresponding L-shaped transmission plate drives the triangular plate to rise, and the triangular plate drives the L-shaped pull plate to rise. The L-shaped pull plate drives the movable circular plate to rise, and the movable circular plate lifts the ore pulp above the movable circular plate. (3) In a defoaming and stirring bucket for flotation according to the present invention, when the movable circular plate rises, the movable spring undergoes tensile deformation. During the process of the L-shaped transmission plate driving the triangular plate to rise, the corresponding limit spring will contact the transmission inclined plate, and the transmission inclined plate will adjust its angle in a direction away from the C-shaped support and limit plate. The transmission inclined plate will press against the right inner wall of the limit spring, and the limit spring will drive the strip plate to move away from the triangular plate. The strip plate will drive the triangular plate to move synchronously. When the triangular plate leaves the L-shaped transmission plate, the movable circular plate will quickly descend under the elastic force of the movable spring. At this time, the mineral particles on the movable circular plate will instantly leave the movable circular plate and freely descend in the round barrel. During this process, the mineral particles will fully contact the defoaming agent and be fully stirred by the centrifugal force of the four-blade paddle, improving the reaction efficiency between the defoaming agent and the mineral particles. (4) In a defoaming and stirring bucket for flotation according to the present invention, during the descent of the movable circular plate, the liquid at the bottom of the movable circular plate will flow into the L-shaped ring hollow block through the leakage groove. At this time, under the action of pressure, the L-shaped ring hollow block will move upward, and the telescopic spring will undergo compressive deformation. When several water inlet grooves on the L-shaped ring hollow block leave the L-shaped ring groove, the liquid entering the L-shaped ring hollow block will be discharged from the water inlet grooves. Since the flow rate of the water inlet grooves is greater than the flow rate of several filter holes, the movable circular plate will quickly descend. During the descent of the movable circular plate, the liquid flow at the bottom of the movable circular plate will cause the sector plate to close the inlet sector groove. At this time, under the conical action of the conical hollow block, the descent speed of the movable circular plate will be increased, preventing the descent speed of the movable circular plate from being too slow and allowing the mineral particles to descend synchronously with the movable circular plate, thereby reducing the mixing and contact effect.

[0020] like Figure 3 As shown, a stirring mechanism 6 is provided at the bottom of the circular skateboard 502, and the stirring mechanism 6 includes a rotating ring 601 rotatably installed at the bottom of the circular skateboard 502, and two L-shaped plates 602 are fixedly installed at the bottom of the rotating ring 601.

[0021] When the circular slide plate 502 descends, the swivel 601 is driven to descend, and the swivel 601 drives the L-shaped plate 602 to descend. Since the L-shaped plate 602 extends into the strip-shaped limiting groove 603, the L-shaped plate 602 moves stably up and down, and the L-shaped plate 602 drives the L-shaped transmission plate 604 to descend.

[0022] like Figure 4 and Figure 5 As shown, a movable circular plate 605 is provided in the barrel 1, the rotating shaft 4 passes through the movable circular plate 605 and is rotatably connected to the movable circular plate 605, a movable spring 606 is fixedly installed at the bottom of the movable circular plate 605, the bottom end of the movable spring 606 is fixedly connected to the barrel 1, a plurality of filter holes 607 are opened on the movable circular plate 605, and two limit blocks 608 are fixedly installed on the outer wall of the movable circular plate 605, and the ends of the two limit blocks 608 that are away from each other extend into two strip limit grooves 603 respectively and are slidably connected to the two strip limit grooves 603 respectively.

[0023] The corresponding L-shaped transmission plate 604 will drive the triangular plate 610 to rise, the triangular plate 610 will drive the L-shaped pull plate 609 to rise, the L-shaped pull plate 609 will drive the movable circular plate 605 to rise, and the movable circular plate 605 will lift the slurry above the movable circular plate 605.

[0024] like Figure 5As shown, two L-shaped pull plates 609 are fixedly installed at the top of the movable circular plate 605. Two triangular plates 610 are respectively slidably installed in the two L-shaped pull plates 609.

One ends of the two L-shaped pull plates 609 away from each other are respectively fixedly installed with limiting springs 612. One ends of the two limiting springs 612 away from each other are respectively fixedly connected with the two strip plates 611.

[0025] The L-shaped transmission plate 604 will contact the triangular plate 610, and the triangular plate 610 will slide into the L-shaped pull plate 609. After the L-shaped transmission plate 604 passes by the triangular plate 610, the triangular plate 610 will pop out under the elastic force of the limiting spring 612.

[0026] As Figure 5 As shown, two unlocking mechanisms 7 are arranged in the barrel 1. The unlocking mechanism 7 includes a fixing plate 701 fixedly installed in the barrel 1. A transmission inclined plate 702 is hingedly installed on the fixing plate 701. A U-shaped support limiting plate 703 is fixedly installed at the bottom of the fixing plate 701. The U-shaped support limiting plate 703 contacts the transmission inclined plate 702. A fixing spring 704 is fixedly installed on the U-shaped support limiting plate 703. The fixing spring 704 contacts the transmission inclined plate 702. A limiting chute 705 is opened at the top of the strip plate 611.

[0027] When the L-shaped transmission plate 604 drives the triangular plate 610 to rise, the corresponding limiting spring 612 will contact the transmission inclined plate 702, and the transmission inclined plate 702 will adjust its angle in the direction away from the U-shaped support limiting plate 703.

[0028] As Figure 4 and Figure 6 As shown, an acceleration mechanism 8 is arranged on the movable circular plate 605. The acceleration mechanism 8 includes an L-shaped ring groove 801 opened on the movable circular plate 605. A plurality of leakage grooves 802 are opened on the bottom inner wall of the L-shaped ring groove 801. An L-shaped ring hollow block 803 is slidably installed in the leakage groove 802. A plurality of water inlet grooves 804 are opened on the outer wall of the L-shaped ring hollow block 803. Two L-shaped long plates 805 are fixedly installed at the top of the movable circular plate 605. Two telescopic springs 806 are respectively fixedly installed on the top inner walls of the two L-shaped long plates 805. The bottom ends of the two telescopic springs 806 are both fixedly connected with the L-shaped ring hollow block 803.

[0029] During the descent of the movable circular plate 605, the liquid at the bottom of the movable circular plate 605 will flow into the L-shaped ring hollow block 803 through the leakage groove 802. At this time, the L-shaped ring hollow block 803 will move upward under the action of pressure. At this time, the telescopic spring 806 will be compressed and deformed. When several water inlet grooves 804 on the L-shaped ring hollow block 803 leave the L-shaped ring groove 801, the liquid entering the L-shaped ring hollow block 803 will be discharged from the water inlet groove 804.

[0030] like Figure 7 As shown, a plurality of conical hollow blocks 807 are fixedly installed at the bottom of the movable circular plate 605, a plurality of water inlet fan-shaped grooves 808 are respectively opened on the outer walls of the plurality of conical hollow blocks 807, a plurality of fan-shaped plates 809 are respectively hingedly installed in the plurality of water inlet fan-shaped grooves 808, and a plurality of support rings 810 are respectively fixedly installed on the plurality of conical hollow blocks 807.

[0031] Since the flow rate of the water inlet groove 804 is greater than the flow rate of several filter holes 607, the movable circular plate 605 will descend rapidly. During the descent of the movable circular plate 605, the liquid flow at the bottom of the movable circular plate 605 will cause the fan plate 809 to close the water inlet fan groove 808. At this time, the conical effect of the conical hollow block 807 will increase the descending speed of the movable circular plate 605, avoiding the movable circular plate 605 from descending too slowly, allowing the mineral particles to descend synchronously with the movable circular plate 605, thereby reducing the effect of mixed contact.

[0032] like Figure 1 - Figure 7 As shown, a flotation method using a defoaming stirring tank, the method steps are as follows: S1: Start the driving motor 3, the driving motor 3 drives the rotating shaft 4 to rotate, the rotating shaft 4 drives the circular slide 502 to rotate under the action of the rectangular groove 501, the circular slide 502 drives the fixed rod 503 to rotate, the fixed rod 503 drives the ring 504 to rotate, the ring 504 reciprocates up and down in the barrel 1 under the action of the thread, and the corresponding circular slide 502 will also move synchronously, the circular slide 502 will drive the circular cylinder 505 to rotate and reciprocate up and down, at this time, the circular slide 502 will drive the circular cylinder 505 to move synchronously, the circular cylinder 505 will drive a number of defoaming teeth 506 to rotate and move up and down at the same time, when the rotating shaft 4 rotates, it will also drive the four-blade paddle 507 to rotate, the four-blade paddle 507 will drive the slurry and defoaming agent in the barrel 1 to rotate, the centrifugal force generated by the rotation of the four-blade paddle 507 will generate a vortex, and the generated bubbles will be moved and concentrated near the vortex near the rotating shaft 4, and in the process of the defoaming teeth 506 rising and falling, the bubbles on the slurry surface and in the vortex including the slurry can be effectively eliminated; S2: During the descent of the circular skateboard 502, the swivel ring 601 will be driven to descend. The swivel ring 601 drives the L-shaped plate 602 to descend. Since the L-shaped plate 602 extends into the strip-shaped limiting groove 603, the L-shaped plate 602 will move stably up and down. The L-shaped plate 602 drives the L-shaped transmission plate 604 to descend. The L-shaped transmission plate 604 will contact the triangular plate 610, and the triangular plate 610 will slide into the L-shaped pull plate 609. After the L-shaped transmission plate 604 passes the triangular plate 610, the triangular plate 610 will pop out under the elastic force of the limiting spring 612. At this time, when the circular skateboard 502 rises, the corresponding L-shaped transmission plate 604 will drive the triangular plate 610 to rise. The triangular plate 610 will drive the L-shaped pull plate 609 to rise. The L-shaped pull plate 609 drives the movable circular plate 605 to rise, and the movable circular plate 605 will lift the pulp above the movable circular plate 605; S3: When the movable circular plate 605 rises, the movable spring 606 undergoes tensile deformation. When the L-shaped transmission plate 604 drives the triangular plate 610 to rise, the corresponding limiting spring 612 will contact the transmission inclined plate 702. The transmission inclined plate 702 will adjust its angle in the direction away from the C-shaped support limiting plate 703. The transmission inclined plate 702 will press against the right inner wall of the limiting spring 612. The limiting spring 612 will drive the strip-shaped plate 611 to move away from the triangular plate 610. The strip-shaped plate 611 will drive the triangular plate 610 to move synchronously. When the triangular plate 610 leaves the L-shaped transmission plate 604, the movable circular plate 605 will quickly descend under the elastic force of the movable spring 606. At this time, the mineral particles on the movable circular plate 605 will instantly leave the movable circular plate 605 and freely descend in the drum 1. During this process, the mineral particles will fully contact the defoaming agent and be fully stirred in cooperation with the centrifugal force of the four-blade paddle 507; S4: During the descent of the movable circular plate 605, the liquid at the bottom of the movable circular plate 605 will flow into the L-shaped ring hollow block 803 through the leakage groove 802. At this time, under the action of pressure, the L-shaped ring hollow block 803 will move upward. At this time, the telescopic spring 806 will undergo compressive deformation. When several water inlet grooves 804 on the L-shaped ring hollow block 803 leave the L-shaped ring groove 801, the liquid entering the L-shaped ring hollow block 803 will be discharged from the water inlet grooves 804. Since the flow rate of the water inlet grooves 804 is greater than the flow rate of several filter holes 607, the movable circular plate 605 will quickly descend. During the descent of the movable circular plate 605, the liquid flow at the bottom of the movable circular plate 605 will cause the sector plate 809 to close the water inlet sector groove 808. At this time, under the conical action of the conical hollow block 807, the descent speed of the movable circular plate 605 will be increased, preventing the descent speed of the movable circular plate 605 from being too slow and allowing the mineral particles to descend synchronously with the movable circular plate 605.

[0033] When in use, the driving motor 3 is started, and the driving motor 3 drives the rotating shaft 4 to rotate. The rotating shaft 4 drives the circular slide 502 to rotate under the action of the rectangular groove 501, and the circular slide 502 drives the fixed rod 503 to rotate, and the fixed rod 503 drives the ring 504 to rotate. The ring 504 moves up and down reciprocatingly in the barrel 1 under the action of the thread, and the corresponding circular slide 502 will also move synchronously. The circular slide 502 will drive the circular cylinder 505 to rotate and reciprocate up and down. At this time, the circular slide 502 will drive the circular cylinder 505 to move synchronously, and the circular cylinder 505 will drive a number of defoaming teeth 506 to rotate and move up and down at the same time. When the rotating shaft 4 rotates, it will also drive the four-blade paddle 507 to rotate. The four-blade paddle 507 will drive the slurry and defoaming agent in the barrel 1 to rotate. The centrifugal force generated by the rotation of the four-blade paddle 507 will generate a vortex, which will move the generated bubbles to the vicinity of the vortex near the rotating shaft 4 and concentrate them. In the process of the defoaming teeth 506 rising and falling, the slurry surface and the vortex including the slurry can be effectively The bubbles are eliminated to improve the effect of foam elimination, and the foam is prevented from being concentrated in the vortex and on the liquid surface, which causes excessive foam overflow and the concentrate to be discharged from the barrel 1, causing waste; in the process of the circular slide 502 descending, the rotating ring 601 is driven to descend, and the rotating ring 601 drives the L-shaped plate 602 to descend. Since the L-shaped plate 602 extends into the strip-shaped limiting groove 603, the L-shaped plate 602 will move up and down stably, and the L-shaped plate 602 drives the L-shaped transmission plate 604 to descend, and the L-shaped transmission plate 604 will contact The triangular plate 610 will slide into the L-shaped pull plate 609. After the L-shaped transmission plate 604 passes through the triangular plate 610, the triangular plate 610 will pop out under the elastic force of the limit spring 612. At this time, when the circular slide plate 502 rises, the corresponding L-shaped transmission plate 604 will drive the triangular plate 610 to rise, the triangular plate 610 will drive the L-shaped pull plate 609 to rise, and the L-shaped pull plate 609 will drive the movable circular plate 605 to rise, and the movable circular plate 605 will lift the slurry above the movable circular plate 605; The movable circular plate 605 rises, and at this time, the movable spring 606 undergoes tensile deformation. When the L-shaped transmission plate 604 drives the triangular plate 610 to rise, the corresponding limit spring 612 will contact the transmission inclined plate 702. The transmission inclined plate 702 will adjust its angle in the direction away from the C-shaped support limit plate 703. The transmission inclined plate 702 will press against the right inner wall of the limit spring 612, and the limit spring 612 will drive the strip-shaped plate 611 to move in the direction away from the triangular plate 610. The strip-shaped plate 611 will drive the triangular plate 610 to move synchronously. When the triangular plate 610 leaves the L-shaped transmission plate 604, the movable circular plate 605 will quickly descend under the elastic force of the movable spring 606. At this time, the mineral particles on the movable circular plate 605 will instantly leave the movable circular plate 605 and freely descend in the drum 1. During this process, the mineral particles will fully contact the defoamer and be fully stirred by the centrifugal force of the four-blade paddle 507 to improve the reaction efficiency between the defoamer and the mineral particles; during the descent of the movable circular plate 605, the liquid at the bottom of the movable circular plate 605 will flow into the L-shaped ring hollow block 803 through the leakage groove 802. At this time, under the action of pressure, the L-shaped ring hollow block 803 will move upward, and at this time, the telescopic spring 806 will undergo compressive deformation. When several water inlet grooves 804 on the L-shaped ring hollow block 803 leave the L-shaped ring groove 801, the liquid entering the L-shaped ring hollow block 803 will be discharged from the water inlet grooves 804. Since the flow rate of the water inlet grooves 804 is greater than the flow rate of several filter holes 607, the movable circular plate 605 will quickly descend. During the descent of the movable circular plate 605, the liquid flow at the bottom of the movable circular plate 605 will cause the sector plate 809 to close the water inlet sector groove 808. At this time, under the conical action of the conical hollow block 807, the descent speed of the movable circular plate 605 will be increased to prevent the descent speed of the movable circular plate 605 from being too slow, allowing the mineral particles to descend synchronously with the movable circular plate 605, thereby reducing the mixing and contact effect.

8. A method for using a defoaming stirring barrel for flotation, using the defoaming stirring barrel for flotation as claimed in claim 7, characterized in that: The method steps are as follows: S1: Start the driving motor (3). The driving motor (3) drives the rotating shaft (4) to rotate. The rotating shaft (4) drives the circular sliding plate (502) to rotate under the action of the rectangular groove (501). The circular sliding plate (502) drives the fixed rod (503) to rotate. The fixed rod (503) drives the ring (504) to rotate. The ring (504) moves up and down reciprocally inside the drum (1) under the action of the thread. Correspondingly, the circular sliding plate (502) also moves synchronously. The circular sliding plate (502) drives the circular cylinder (505) to rotate and move up and down reciprocally. At this time, the circular sliding plate (502) drives the circular cylinder (505) to move synchronously. The circular cylinder (505) drives a plurality of defoaming teeth (506) to rotate and move up and down simultaneously. When the rotating shaft (4) rotates, it also drives the four-blade paddle (507) to rotate. The four-blade paddle (507) drives the pulp and defoaming agent inside the drum (1) to rotate and mix. The centrifugal force generated by the rotation of the four-blade paddle (507) generates a vortex, and moves and concentrates the generated bubbles towards the vortex near the rotating shaft (4). During the ascending and descending rotation process of the defoaming teeth (506), the bubbles on the slurry surface, in the vortex and including those in the slurry can be effectively eliminated; S2: During the downward movement of the circular skateboard (502), the swivel ring (601) is driven to descend. The swivel ring (601) drives the L-shaped plate (602) to descend. Since the L-shaped plate (602) extends into the strip-shaped limiting groove (603), the L-shaped plate (602) can move stably up and down. The L-shaped plate (602) drives the L-shaped transmission plate (604) to descend. The L-shaped transmission plate (604) will contact the triangular plate (610). The triangular plate (610) will slide into the L-shaped pulling plate (609). After the L-shaped transmission plate (604) passes by the triangular plate (610), the triangular plate (610) will pop out under the elastic force of the limiting spring (612). At this time, when the circular skateboard (502) ascends, the corresponding L-shaped transmission plate (604) will drive the triangular plate (610) to ascend. The triangular plate (610) will drive the L-shaped pulling plate (609) to ascend. The L-shaped pulling plate (609) drives the movable circular plate (605) to ascend, and the movable circular plate (605) will lift the pulp above the movable circular plate (605); S3: When the movable circular plate (605) ascends, the movable spring (606) undergoes tensile deformation. When the L-shaped transmission plate (604) drives the triangular plate (610) to ascend, the corresponding limiting spring (612) will contact the transmission inclined plate (702). The transmission inclined plate (702) will adjust its angle in the direction away from the C-shaped support limiting plate (703). The transmission inclined plate (702) will press against the right inner wall of the limiting spring (612). The limiting spring (612) will drive the strip-shaped plate (611) to move away from the triangular plate (610). The strip-shaped plate (611) will drive the triangular plate (610) to move synchronously. When the triangular plate (610) leaves the L-shaped transmission plate (604), the movable circular plate (605) will quickly descend under the elastic force of the movable spring (606). At this time, the mineral particles on the movable circular plate (605) will instantaneously leave the movable circular plate (605) and freely descend in the drum (1). During this process, the mineral particles will come into full contact with the defoaming agent and be fully stirred by the centrifugal force of the four-blade paddle (507); S4: During the descent of the movable circular plate (605), the liquid at the bottom of the movable circular plate (605) will flow into the L-shaped hollow ring block (803) through the leakage groove (802). At this time, the L-shaped hollow ring block (803) will move upward under the action of pressure. At this time, the telescopic spring (806) will be compressed and deformed. When the several water inlet grooves (804) on the L-shaped hollow ring block (803) leave the L-shaped ring groove (801), the liquid entering the L-shaped hollow ring block (803) will be discharged from the water inlet groove (804). The flow rate of the water tank (804) is greater than the flow rates of the plurality of filter holes (607), so the movable circular plate (605) will descend rapidly. During the descent of the movable circular plate (605), the liquid flow at the bottom of the movable circular plate (605) will cause the fan-shaped plate (809) to close the water inlet fan-shaped groove (808). At this time, the conical effect of the conical hollow block (807) will increase the descent speed of the movable circular plate (605), thereby preventing the movable circular plate (605) from descending too slowly, and allowing the mineral particles to descend synchronously with the movable circular plate (605).
