The ball 550 is rotatably connected to the inner circumference of the valve body 540. One end of the first pipe 520 is connected to one of the first discharge ports 220. The other end of the first pipe 520 is connected to the other end of the valve body 540. One end of the second pipe 530 is connected to one of the second discharge ports 320. The other end of the second pipe 530 passes through the lower end of the upper housing 100 and extends downward. The second rotating component 510 is connected to the ball 550 to realize its rotation, thereby opening and closing the second feed port 310.

[0032] In this embodiment: the upper end of the lower housing 120 is open, and a second circular groove 140 is formed in the middle of its lower inner wall. A receiving cylinder 150 is fixed in the second circular groove 140. The upper end of the receiving cylinder 150 is open. A third discharge port 130 is provided at the left end of the lower housing 120 and communicates with the interior of the lower housing 120. A fourth discharge port 160 is provided at the right end of the receiving cylinder 150 and communicates with the interior of the receiving cylinder 150. The fourth discharge port 160 passes through the right end of the lower housing 120 and extends to the right. The front end of the upper housing 100 is open, and five evenly distributed first circular grooves 110 are formed in the lower inner wall of the upper housing 100.

[0033] Each of the five first circular troughs 110 contains a hydrocyclone separator 300. Each of the hydrocyclone separators 300 has a second discharge port 320 at both its upper and lower ends. The upper discharge ports 320 are overflow ports used to discharge smaller particles of sludge. The lower discharge ports 320 are sand discharge ports used to discharge larger particles of coarse sand. All the coarse sand discharge ports face downwards and are aligned with the lower inner wall of the lower casing 120. Each overflow port has a second pipe 530 fixed inside it.

[0034] Multiple second pipes 530 penetrate the lower end of the upper shell 100 and are aligned with the opening at the upper end of the receiving cylinder 150. A mixing tank 200 is fixed in the middle of the lower inner wall of the upper shell 100. A first feed inlet 210 is provided on the left side of the circumferential surface of the mixing tank 200 for injecting slurry. Five evenly distributed first discharge outlets 220 are provided at the lower end of the mixing tank 200 for discharging slurry. The five second feed inlets 310 are respectively connected to the five first discharge outlets 220 through five first pipes 520 and five valve bodies 540.

[0035] The valve body 540 has openings at both the left and right ends, and a spherical groove is provided inside. A hollow ball 550 is rotatably connected inside the spherical groove. The ball 550 rotates horizontally along the spherical groove. The front and rear parts of the circumference of the ball 550 are also open.

[0036] When the device is in the initial state, the two openings on the five spheres 550 are perpendicular to the two openings on the five valve bodies 540, and the five valve bodies 540 are in the closed state, so that the slurry cannot enter the five cyclone separation tanks 300. In the driving mechanism 600, the intermittent driving component 610 drives the first transmission component 620 and the second transmission component 630 alternately. When one of them is running, the other will automatically stop.

[0037] When the desliming operation is performed, after the untreated slurry is injected into the stirring tank 200 through the first feeding port 210, the intermittent driving component 610 can drive the first transmission component 620 to run, and the second transmission component 630 does not run at this time. The five valve bodies 540 are in the closed state, and the first transmission component 620 drives the first rotating component 410 to run, and then drives the two second rotating rods 420 to make a circular motion around the midpoint of the stirring tank 200 and a self-rotation around the midpoint of the second rotating rod 420, so that the multiple stirring blades 430 on the two second rotating rods 420 make a revolution and a self-rotation to form two mutually intersecting vortexes, thereby fully stirring and mixing the slurry, and uniformly distributing the sludge and coarse sand in the slurry.

[0038] Then the intermittent driving component 610 drives the second transmission component 630 to run and stops the first transmission component 620, and the second transmission component 630 drives the second rotating component 510 to run, and then drives the five valve bodies 540 to rotate in the horizontal direction respectively, until the openings on the five valve bodies 540 are coincided with the openings on the five spheres 550, so that the five valve bodies 540 are opened, thereby enabling the mixed slurry to naturally enter the five first pipes 520 through the five first discharge ports 220 under the action of gravity.

[0039] The volume of the stirring tank 200 is fixed. The water level monitor 700 is arranged to monitor whether the material in the tank reaches the optimal processing capacity. When the stirring stops, the PLC controller 800 receives the water level signal, and its logical judgment is that a batch of material has been stirred and completed, and should enter the discharge stage. Therefore, it will first send a stop signal, and then start the valve opening program. This is an automatic process control based on PLC.

[0040] Then the slurry is injected into the five cyclone separation tanks 300 through the five valve bodies 540 and the five second feeding ports 310 in the tangential direction, and then the slurry forms an inner and outer vortex flow field in the circumferential inner wall of the five cyclone separation tanks 300 under the action of centrifugal force. The lighter sludge is discharged from the five overflow ports into the five second pipes 530 through the inner vortex flow field.

[0041] The heavy coarse sand is discharged from the five grit outlets via the outer vortex flow field and injected into the lower shell 120 via the third discharge port, thereby completing the desliming operation of the ore slurry. For those skilled in the art, the internal structure of the cyclone separation tank 300 described above is prior art and will not be described in detail.

The intermittent driving component 610 comprises a double-shaft motor 611, two second fixed discs 612 and two groups of connecting assemblies 613, the double-shaft motor 611 is connected to the inner wall of one side of the upper shell 100, the two second fixed discs 612 are respectively connected to the proximal ends of one of the second spur gears 622 and one of the third spur gears 633.

When the motor reverses, the situation is just the opposite. The spring 6136 provides a continuous pressing force for the pawl 6135 to ensure that the pawl 6135 can be timely popped up and meshed with the ratchet teeth, thereby ensuring the reliability of the transmission.

Due to the engagement between the internal gear 414 and the two first spur gears 415, the two first spur gears 415 are also driven to rotate, so that the two second rotary rods 420 are driven to make circumferential motion based on the midpoint of the stirring tank 200 and are also driven to rotate. Thus, the plurality of stirring blades 430 are driven to make revolution and rotation, and two vortexes which are interlaced with each other are formed, so that the ore pulp in the stirring tank 200 is stirred.

The fifth rotary rod 621 plays a role in supporting the rotation of the second spur gear 622 located on the right side.

[0050] The circumferential surface of the five third rotating rods 511 on the upper side is fixed with the fourth spur gears 634, and the lower inner wall right part of the upper shell 100 is rotatably provided with two sixth rotating rods 632 distributed left and right, and the circumferential surface of the two sixth rotating rods 632 is fixed with the third spur gears 633. The third spur gears 633 on the right side and the circumferential surface of the five fourth spur gears 634 are connected in a hexagonal distribution by the chain 631.

[0051] When the third spur gear 633 on the left side is rotated, the third spur gear 633 on the right side and the two sixth rotating rods 632 are driven to rotate, and the five fourth spur gears 634 are driven to rotate through the transmission of the chain 631, thereby driving the five third rotating rods 511 on the upper side and the five balls 550 to rotate to control the opening and closing of the five valve bodies 540. The two sixth rotating rods 632 serve to support the rotation of the two third spur gears 633.

[0052] The lower end of the second spur gear 622 on the right side and the upper end of the third spur gear 633 on the right side are fixed with the second fixed disc 612, the proximal ends of the two second fixed discs 612 are fixed with the inner ratchet wheel 6133, the two inner ratchet wheels 6133 are intermittently engaged with the four pawls 6135, the teeth of the two inner ratchet wheels 6133 are opposite in direction, and the teeth of the two pawls 6135 on the upper side and the two pawls 6135 on the lower side are also opposite in direction.

[0053] When the double-shaft motor 611 is running forward, the two output shafts of the double-shaft motor 611 rotate forward, thereby driving the two fourth rotating rods 6131, the two first fixed discs 6132, the two rotating blocks 6134, and the four pawls 6135 to rotate. At this time, the rotating direction of the two pawls 6135 on the lower side is opposite to the direction of the ratchet teeth of the inner ratchet wheel 6133 on the lower side, and they are not engaged, so the two pawls 6135 on the lower side are constantly rotating in a small amplitude under the compression and rebound action of the two springs 6136, and the inner ratchet wheel 6133 on the lower side is not driven by the two pawls 6135 on the lower side.

[0054] At this time, the two third spur gears 633 do not rotate, and the rotating direction of the two pawls 6135 on the upper side is opposite to the direction of the ratchet teeth of the inner ratchet wheel 6133 on the upper side, and they are engaged.

[0055] Therefore, the inner ratchet wheel 6133 on the upper side is driven by the two pawls 6135 on the upper side, thereby driving the two second spur gears 622 to rotate. For those skilled in the art, the above-mentioned double-shaft motor 611 is prior art, and will not be described in detail.

[0056] Embodiment three, this embodiment is made on the basis of the improvement of embodiment two, please see Figures 1-10 The circumferential inner wall of the stirring tank 200 is connected with a water level monitor 700, one side end of the lower shell 120 is connected with a PLC controller 800, and the PLC controller 800 is signal connected with the double-shaft motor 611 and the water level monitor 700; The lower inner wall of the upper shell 100 is connected with a plurality of support frames 900, and the plurality of support frames 900 are connected to the circumferential surface of the plurality of valve bodies 540 respectively; The plurality of cyclone separation tanks 300 are connected to the lower inner wall of the upper shell 100 through bolts; The lower inner wall of the lower shell 120 is inclined to the third discharge port 130, and the lower inner wall of the receiving cylinder 150 is inclined to the fourth discharge port 160.

[0057] In this embodiment: the water level monitor 700 can monitor the water level change in the stirring tank 200, when the water level in the stirring tank 200 reaches the threshold value set by the water level monitor 700.

[0058] The water level monitor 700 will be triggered to transmit the water level signal to the PLC controller 800, and the PLC controller 800 will control the double-shaft motor 611 to stop forward rotation and thus stop stirring, and control the double-shaft motor 611 to reverse rotation and thus open the five valve bodies 540 to discharge the ore pulp in the stirring tank 200 into the five cyclone separation tanks 300 for desliming operation.

[0059] The circumferential surface of the five valve bodies 540 is fixed with support frames 900 at both ends, and the ten support frames 900 are fixed to the lower inner wall of the upper shell 100, which can enhance the fixation of the five valve bodies 540 and make them more stable during operation without shaking.

[0060] The lower inner wall of the upper shell 100 and the plurality of cyclone separation tanks 300 are both provided with threaded holes, the threaded holes are matched with each other, and bolts are threadedly connected in the adjacent two threaded holes, which can enhance the fixation of the five cyclone separation tanks 300, so that the five cyclone separation tanks 300 will not shake violently when the ore pulp rotates at high speed in the five cyclone separation tanks 300, causing damage to the device.

[0061] The lower inner wall of the lower shell 120 is a left side inclined surface inclined to the third discharge port 130, and the lower inner wall of the receiving cylinder 150 is a right side inclined surface inclined to the fourth discharge port 160, which can assist the flow of the two fluids containing coarse sand and slurry in the lower inner wall of the lower shell 120 and the receiving cylinder 150 and flow out through the third discharge port 130 and the fourth discharge port 160.
