Description

Technical Field

[0001] The present invention relates to the technical field of defoaming stirring equipment, and specifically relates to a defoaming stirring barrel for flotation and its usage method. Background Technique

[0002] The defoaming stirring barrel for flotation is a key equipment in the beneficiation process used to eliminate flotation foam, promote pulp mixing, and ensure the efficient and stable progress of the flotation process. In the fields of non-ferrous metal beneficiation, coal flotation, etc., if a large amount of foam generated during the flotation operation is not processed in a timely manner, it will affect the subsequent processes and reduce the beneficiation recovery rate. And this stirring barrel can accurately solve the foam problem and improve the beneficiation quality and efficiency.

[0003] When defoaming the pulp in the barrel, most methods eliminate foam at a fixed liquid level. Only the foam generated at the fixed liquid level is eliminated, so the foam generated below this liquid level cannot be processed in a timely manner. The newly generated foam below the liquid level may carry the target minerals and sink again or be carried away by the pulp flow, making these target minerals unable to be effectively recovered. Correspondingly, when the foam rises to the liquid surface, the concentrate will also leave the stirring barrel due to aggregation, thereby reducing the concentrate recovery rate. Summary of the Invention

[0004] The purpose of the present invention is to provide a defoaming stirring barrel for flotation and its usage method to solve the problem that only the foam is removed at a fixed liquid level, so the foam generated below this liquid level cannot be processed in a timely manner. The newly generated foam below the liquid level may carry the target minerals and sink again or be carried away by the pulp flow, making these target minerals unable to be effectively recovered. Correspondingly, when the foam rises to the liquid surface, the concentrate will also leave the stirring barrel due to aggregation, thereby reducing the concentrate recovery rate.

[0005] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0006] The present invention is a defoaming stirring barrel for flotation, including a round barrel. The top of the round barrel is fixedly installed with a mounting frame. The top of the mounting frame is fixedly installed with a driving motor. A rotating shaft is rotatably installed on the mounting frame. The rotating shaft penetrates the mounting frame. The bottom end of the rotating shaft is rotatably connected to the inner wall of the bottom of the round barrel. The output shaft of the driving motor is fixedly connected to the rotating shaft. It further includes:

[0007] A defoaming mechanism. The defoaming mechanism includes a rectangular groove opened on the rotating shaft. A circular slide plate is slidably sleeved on the rectangular groove. A plurality of fixing rods are fixedly installed on the outer wall of the circular slide plate. One end of each of the plurality of fixing rods away from each other is fixedly installed with a ring. The outer wall of the ring is in reciprocating threaded connection with the inner wall of the round barrel. A circular cylinder is fixedly installed through the circular slide plate. A plurality of defoaming teeth are fixedly installed on the outer wall of the circular cylinder. A four-blade paddle is fixedly installed on the rotating shaft.

[0008] Further, a stirring mechanism is provided at the bottom of the circular skateboard. The stirring mechanism includes a rotating ring rotatably mounted at the bottom of the circular skateboard. Two L-shaped plates are fixedly mounted at the bottom of the rotating ring. Two strip-shaped limiting grooves are formed on the inner wall of the barrel. One end of each of the two L-shaped plates away from each other extends into the two strip-shaped limiting grooves and is respectively slidably connected to the two strip-shaped limiting grooves. L-shaped transmission plates are respectively fixedly mounted at the bottoms of the two L-shaped plates.

[0009] Further, a movable circular plate is arranged in the barrel. The rotating shaft penetrates through the movable circular plate and is rotatably connected to the movable circular plate. A movable spring is fixedly mounted at the bottom of the movable circular plate. The bottom end of the movable spring is fixedly connected to the barrel. A plurality of filter holes are formed in the movable circular plate. Two limiting blocks are fixedly mounted on the outer wall of the movable circular plate. One end of each of the two limiting blocks away from each other extends into the two strip-shaped limiting grooves and is respectively slidably connected to the two strip-shaped limiting grooves.

[0010] Further, two L-shaped pulling plates are fixedly mounted at the top of the movable circular plate. Triangular plates are respectively slidably mounted 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 triangular plates away from each other is respectively fixedly mounted with a strip-shaped plate. 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. Limiting springs are respectively fixedly mounted at one end of each of the two L-shaped pulling plates away from each other. One end of each of the two limiting springs away from each other is fixedly connected to the two strip-shaped plates.

[0011] Further, two unlocking mechanisms are arranged in the barrel. The unlocking mechanism includes a fixing plate fixedly mounted in the barrel. A transmission inclined plate is hingedly mounted on the fixing plate. A U-shaped support limiting plate is fixedly mounted at the bottom of the fixing plate. The U-shaped support limiting plate is in contact with the transmission inclined plate. A fixing spring is fixedly mounted on the U-shaped support limiting plate. The fixing spring is in contact with the transmission inclined plate. A limiting sliding groove is formed at the top of the strip-shaped plate.

[0012] Further, 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 mounted 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 mounted at the top of the movable circular plate. Telescopic springs are respectively fixedly mounted on the inner walls of the tops of the two L-shaped long plates. The bottom ends of the two telescopic springs are both fixedly connected to the L-shaped ring hollow block.

[0013] Furthermore, a number of conical hollow blocks are fixedly installed at the bottom of the movable circular plate. A number of water inlet fan-shaped grooves are respectively formed in the outer walls of the conical hollow blocks. Fan-shaped plates are respectively hingedly installed in the water inlet fan-shaped grooves. Support rings are respectively fixedly installed on the conical hollow blocks.

[0014] Furthermore, a method for defoaming and stirring a flotation barrel is as follows:

[0015] 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 number of defoaming teeth to rotate and move up and down simultaneously. When the rotating shaft rotates, it will also drive the four-blade paddle to rotate. The four-blade paddle 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 paddle will generate a vortex, moving the generated bubbles towards the vicinity of the vortex close to the rotating shaft and concentrating them. During the ascending and descending rotation process of the defoaming teeth, the bubbles on the slurry surface, in the vortex, and including those in the slurry can be effectively eliminated;

[0016] S2: During the downward movement of the circular slide plate, 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 limiting groove, the L-shaped plate will move stably up and down. The L-shaped plate drives the L-shaped transmission plate to descend. The L-shaped transmission plate will contact the triangular plate, and 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 limiting spring. At this time, when the circular slide plate ascends, the corresponding L-shaped transmission plate will drive the triangular plate to ascend. The triangular plate will drive the L-shaped pull plate to ascend. The L-shaped pull plate drives the movable circular plate to ascend, and the movable circular plate will lift the pulp above the movable circular plate;

[0017] S3: When the movable circular plate ascends, the movable spring undergoes tensile deformation. When the L-shaped transmission plate drives the triangular plate to ascend, the corresponding limiting spring will contact the transmission inclined plate. The transmission inclined plate will adjust its angle in the direction away from the C-shaped support limiting plate. The transmission inclined plate will press against the right inner wall of the limiting spring. The limiting 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 paddle;

[0018] 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, 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 that has entered 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 that 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 sector plate to close the water 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 enabling the mineral particles to descend synchronously with the movable circular plate.

[0019] The present invention has the following beneficial effects:

[0020] (1) For the defoaming stirring barrel for flotation of the present invention, when in use, the driving motor is started, and the driving motor drives the rotating shaft to rotate. The rotating shaft drives the circular sliding plate to rotate under the action of the rectangular groove. The circular sliding plate drives the fixed rod to rotate, and the fixed rod drives the circular ring to rotate. The circular ring moves up and down reciprocally in the cylindrical barrel under the action of the thread. Correspondingly, the circular sliding plate will also move synchronously. The circular sliding plate will drive the circular cylinder to rotate and move up and down reciprocally. At this time, the circular sliding plate will drive the circular cylinder to move synchronously. The circular cylinder will drive several defoaming teeth to rotate and move up and down simultaneously. When the rotating shaft rotates, it will also drive the four-blade paddle to rotate. The four-blade paddle will drive the pulp and defoaming agent in the cylindrical barrel to rotate and mix. The centrifugal force generated by the rotation of the four-blade paddle will generate a vortex, moving the generated bubbles towards the vicinity of the vortex close to the rotating shaft and concentrating them. During the ascending and descending rotation process of the defoaming teeth, the bubbles on the slurry surface, in the vortex, and including those in the slurry can be effectively eliminated, improving the defoaming effect, preventing the bubbles from concentrating at the vortex and on the slurry surface, resulting in excessive foam overflowing and carrying the concentrate out of the cylindrical barrel, causing waste, and the concentrate sinking again;

[0021] (2) For the defoaming stirring barrel for flotation of the present invention, during the descent of the circular sliding plate, it will drive the rotating ring 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 will move up and down stably. The L-shaped plate drives the L-shaped transmission plate to descend, and the L-shaped transmission plate will contact the triangular plate. The triangular plate will slide into the L-shaped pulling plate. After the L-shaped transmission plate passes the triangular plate, the triangular plate will pop out under the elastic force of the limiting spring. At this time, when the circular sliding plate ascends, the corresponding L-shaped transmission plate will drive the triangular plate to ascend, the triangular plate will drive the L-shaped pulling plate to ascend, and the L-shaped pulling plate drives the movable circular plate to ascend, and the movable circular plate will lift the pulp above the movable circular plate;

[0022] (3) In a defoaming stirring barrel for flotation of 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 limiting spring will contact the transmission inclined plate, and the transmission inclined plate will adjust its angle in the direction away from the C-shaped support limiting plate. The transmission inclined plate will press against the right inner wall of the limiting spring, and the limiting 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.

[0023] (4) In a defoaming stirring barrel for flotation of 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 fan-shaped plate to close the water inlet fan-shaped 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.

[0024] Of course, it is not necessary for any product implementing the present invention to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of this invention, rather than all the embodiments. Based on the embodiments of this invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this invention.

[0036] Please refer to Figure 1 - Figure 7 As shown, this invention is a defoaming and stirring barrel for flotation, including a cylindrical barrel 1. A mounting frame 2 is fixedly installed at the top of the cylindrical barrel 1. A driving motor 3 is fixedly installed at the top of the mounting frame 2. A rotating shaft 4 is rotatably installed on the mounting frame 2. The rotating shaft 4 penetrates through the mounting frame 2. The bottom end of the rotating shaft 4 is rotatably connected to the inner wall of the bottom of the cylindrical barrel 1. The output shaft of the driving motor 3 is fixedly connected to the rotating shaft 4. It further includes:

[0037] Defoaming mechanism 5, the defoaming mechanism 5 includes a rectangular groove 501 opened on the rotating shaft 4, a circular sliding plate 502 is slidably sleeved on the rectangular groove 501, a plurality of fixing rods 503 are fixedly installed on the outer wall of the circular sliding plate 502, a circular ring 504 is fixedly installed at one end of the plurality of fixing rods 503 away from each other, the outer wall of the circular ring 504 is reciprocally threadedly connected with the inner wall of the cylindrical barrel 1, a circular cylinder 505 is fixedly installed through the circular sliding plate 502, a plurality of defoaming teeth 506 are fixedly installed on the outer wall of the circular cylinder 505, and a four-blade paddle 507 is fixedly installed on the rotating shaft 4.

[0038] As Figure 3 shown, a stirring mechanism 6 is arranged at the bottom of the circular sliding plate 502. The stirring mechanism 6 includes a rotating ring 601 rotatably installed at the bottom of the circular sliding plate 502. Two L-shaped plates 602 are fixedly installed at the bottom of the rotating ring 601. Two strip-shaped limiting grooves 603 are opened on the inner wall of the cylindrical barrel 1. One end of the two L-shaped plates 602 away from each other respectively extends into the two strip-shaped limiting grooves 603 and is respectively slidably connected with the two strip-shaped limiting grooves 603. L-shaped transmission plates 604 are respectively fixedly installed at the bottoms of the two L-shaped plates 602.

[0039] During the downward movement of the circular sliding plate 502, the rotating ring 601 will be driven to descend. The rotating ring 601 drives the L-shaped plates 602 to descend. Since the L-shaped plates 602 extend into the strip-shaped limiting grooves 603, the L-shaped plates 602 will move stably up and down, and the L-shaped plates 602 drive the L-shaped transmission plates 604 to descend.

[0040] As Figure 4 and Figure 5 shown, a movable circular plate 605 is arranged in the cylindrical barrel 1. The rotating shaft 4 penetrates through the movable circular plate 605 and is rotatably connected with 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 with the cylindrical barrel 1. A plurality of filter holes 607 are opened on the movable circular plate 605. Two limiting blocks 608 are fixedly installed on the outer wall of the movable circular plate 605. One end of the two limiting blocks 608 away from each other respectively extends into the two strip-shaped limiting grooves 603 and is respectively slidably connected with the two strip-shaped limiting grooves 603.

[0041] Correspondingly, the L-shaped transmission plate 604 will drive the triangular plate 610 to rise. The triangular plate 610 will drive the L-shaped pulling plate 609 to rise. The L-shaped pulling plate 609 drives the movable circular plate 605 to rise. The movable circular plate 605 will lift the pulp above the movable circular plate 605.

[0042] As Figure 5As shown in the figure, two L-shaped pull plates 609 are fixedly installed at the top of the movable circular plate 605. Two triangular plates 610 are slidably installed in the two L-shaped pull plates 609 respectively. One end of the two triangular plates 610 close to each other extends outside the two L-shaped pull plates 609 respectively. One end of the two triangular plates 610 away from each other is fixedly installed with a strip-shaped plate 611 respectively. One end of the two strip-shaped plates 611 away from each other extends outside the two L-shaped pull plates 609 and is respectively slidably connected with the two L-shaped pull plates 609. One end of the two L-shaped pull plates 609 away from each other is fixedly installed with a limit spring 612 respectively. One end of the two limit springs 612 away from each other is fixedly connected with the two strip-shaped plates 611 respectively.

[0043] 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 limit spring 612.

[0044] As Figure 5 As shown in the figure, two unlocking mechanisms 7 are arranged in the cylinder 1. The unlocking mechanism 7 includes a fixing plate 701 fixedly installed in the cylinder 1. A transmission inclined plate 702 is hingedly installed on the fixing plate 701. A U-shaped support limit plate 703 is fixedly installed at the bottom of the fixing plate 701. The U-shaped support limit plate 703 is in contact with the transmission inclined plate 702. A fixing spring 704 is fixedly installed on the U-shaped support limit plate 703. The fixing spring 704 is in contact with the transmission inclined plate 702. A limit sliding groove 705 is opened at the top of the strip-shaped plate 611.

[0045] 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, and the transmission inclined plate 702 will adjust its angle in the direction away from the U-shaped support limit plate 703.

[0046] As Figure 4 and Figure 6 As shown in the figure, 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 fixedly installed on the top inner walls of the two L-shaped long plates 805 respectively. The bottom ends of the two telescopic springs 806 are fixedly connected with the L-shaped ring hollow block 803.

[0047] During the downward movement 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 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 that has entered the L-shaped ring hollow block 803 will be discharged from the water inlet grooves 804.

[0048] As Figure 7 shown, several conical hollow blocks 807 are fixedly installed at the bottom of the movable circular plate 605. Several water inlet fan-shaped grooves 808 are respectively formed on the outer walls of the several conical hollow blocks 807. Fan-shaped plates 809 are respectively hingedly installed in the several water inlet fan-shaped grooves 808. Support rings 810 are respectively fixedly installed on the several conical hollow blocks 807.

[0049] 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 quickly descend. During the downward movement 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, under the conical action of the conical hollow block 807, the downward speed of the movable circular plate 605 will be increased, avoiding the situation that the downward speed of the movable circular plate 605 is too slow, enabling the mineral particles to descend synchronously with the movable circular plate 605, thereby reducing the effect of mixed contact.

[0050] As Figure 1 - Figure 7 shown, a method for defoaming and stirring a flotation barrel is as follows:

[0051] S1: Start the drive motor 3. The drive motor 3 drives the rotating shaft 4 to rotate. Under the action of the rectangular groove 501, the rotating shaft 4 drives the circular slide plate 502 to rotate. The circular slide 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 in the drum 1 under the action of the thread. Correspondingly, the circular slide plate 502 will also move synchronously. The circular slide plate 502 will drive the circular cylinder 505 to rotate and move up and down reciprocally. At this time, the circular slide plate 502 will drive the circular cylinder 505 to move synchronously. The circular cylinder 505 will drive several defoaming teeth 506 to rotate and move up and down simultaneously. 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 pulp and defoaming agent in the drum 1 to rotate and mix. The centrifugal force generated by the rotation of the four-blade paddle 507 will generate a vortex, moving the generated bubbles towards the vicinity of the vortex close to the rotating shaft 4 and concentrating them. 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;

[0052] S2: When the circular slide 502 descends, the rotating ring 601 will be driven to descend, and the rotating ring 601 will drive 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 will drive the L-shaped transmission plate 604 to descend, and 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 through 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 slide 502 rises, the corresponding L-shaped transmission plate 604 will drive the triangular plate 610 to rise, and 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 ore pulp above the movable circular plate 605;

[0053] S3: The movable circular plate 605 rises, and the movable spring 606 is stretched and deformed. 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, and the transmission inclined plate 702 will adjust its angle in the direction away from the 匚-shaped support limit plate 703. The transmission inclined plate 702 will support the right inner wall of the limit spring 612, and the limit spring 612 will drive the strip plate 611 to move in the direction away from the triangular plate 610. The strip 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 drop rapidly 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 fall freely in the barrel 1. In this process, the mineral particles will fully contact with the defoaming agent and be fully stirred with the centrifugal force of the four-blade paddle 507.

[0054] 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, the L-shaped ring hollow block 803 will move upward under the action of pressure, and the telescopic spring 806 will be compressed and deformed. When the 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. Since the flow rate of the water inlet groove 804 is greater than the flow rate of the 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-shaped plate 809 to close the water inlet fan-shaped groove 808. At this time, the descending speed of the movable circular plate 605 will be increased under the conical action of the conical hollow block 807 to prevent the movable circular plate 605 from descending too slowly, so that the mineral particles and the movable circular plate 605 can descend synchronously.

[0055] When in use, start the drive motor 3. The drive motor 3 drives the rotating shaft 4 to rotate. Under the action of the rectangular groove 501, the rotating shaft 4 drives the circular slide plate 502 to rotate. The circular slide plate 502 drives the fixed rod 503 to rotate. The fixed rod 503 drives the ring 504 to rotate. Under the action of the thread, the ring 504 moves up and down reciprocally in the drum 1. Correspondingly, the circular slide plate 502 also moves synchronously. The circular slide plate 502 drives the circular cylinder 505 to rotate and move up and down reciprocally. At this time, the circular slide plate 502 drives the circular cylinder 505 to move synchronously. The circular cylinder 505 drives a number 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 in the drum 1 to rotate and mix. The centrifugal force generated by the rotation of the four-blade paddle 507 generates a vortex, which moves and concentrates the generated bubbles towards the vicinity of the vortex close to 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, improving the foam elimination effect and preventing the foam from concentrating at the vortex and on the liquid surface, resulting in excessive foam overflowing and carrying the concentrate out of the drum 1, causing waste. During the descending process of the circular slide plate 502, it drives the rotating ring 601 to descend. The rotating ring 601 drives the L-shaped plate 602 to descend. Since the L-shaped plate 602 extends into the strip-shaped limit groove 603, the L-shaped plate 602 moves stably up and down. The L-shaped plate 602 drives the L-shaped transmission plate 604 to descend. The L-shaped transmission plate 604 contacts the triangular plate 610, and the triangular plate 610 slides into the L-shaped pull plate 609. After the L-shaped transmission plate 604 passes the triangular plate 610, the triangular plate 610 pops out under the elastic force of the limit spring 612. At this time, when the circular slide plate 502 ascends, the corresponding L-shaped transmission plate 604 drives the triangular plate 610 to ascend. The triangular plate 610 drives the L-shaped pull plate 609 to ascend. The L-shaped pull plate 609 drives the movable circular plate 605 to ascend, and the movable circular plate 605 raises the pulp above the movable circular plate 605.

[0056] 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 plate 611 to move away from the triangular plate 610. The strip 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 by the centrifugal force of the four-leaf paddle 507 to improve the reaction efficiency between the defoaming agent 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.

When the rotating shaft (4) rotates, the four-blade paddle (507) is also driven to rotate. The four-blade paddle (507) drives the slurry and defoaming agent in the circular cylinder (1) to rotate.
