Inside the sedimentation pool, the liquid level gradually rises with the injection of the water flow, and the rising liquid level triggers the feedback component to work. When the feedback component works, it gradually triggers the discharge component to work. The discharge component sends the flocculant into the sedimentation pool and triggers the motor to mix and stir it. At this time, the liquid level continues to rise until the discharge component triggers the reset delay switch to close the electric control valve, cut off the drain pipe, and at the same time releases the limit of the pull-out plate by the limit component.

The guide bayonet on the pull-out plate is slidably engaged with the slide bar, thereby limiting the pull-out plate and preventing it from being pulled outward. When the lifting block slides to the working state where the blanking assembly triggers the reset delay switch to close the electric control valve, the side opening on the slide bar slides to the position opposite to the guide bayonet, thereby making the constraint between the guide bayonet and the slide bar contact, and the pull-out plate can be pulled outward.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0019] See also Figure 1-9The present invention provides a technical solution: a magnetic mineral separation washing and sedimentation device, comprising a sedimentation tank 1 and a distribution tank 2, wherein a plurality of mounting slots 21 are provided on the inner walls of both sides of the sedimentation tank 1 near the top, a blanking plate 10 is provided between two opposite mounting slots 21, a blanking assembly is provided inside the blanking plate 10, a plurality of mounting slots 21 are provided with jacking slots 22 on the inner bottom surfaces, a plurality of jacking slots 22 are provided with feedback assemblies between the plurality of jacking slots 22, a rectangular slide cavity 19 is provided on the inner bottom surfaces of the two jacking slots 22 near the two sides of the sedimentation tank 1, and a limit assembly is provided inside the two rectangular slide cavities 19; The distributing pool 2 is located on one side of the sedimentation pool 1, and a bracket 3 is fixed to the bottom of the distributing pool 2. The bottom of the bracket 3 is fixed to one side of the bottom of the sedimentation pool 1. A diversion channel 4 is provided near the bottom edge of the front side of the sedimentation pool 1, and a filter plate 6 is fixed between the inner wall of the distributing pool 2 near the bottom edge. The bottom of the distributing pool 2 is connected with a drainage pipe 5 near the front and rear edges. One end of the two drainage pipes 5 passes through the interior of the sedimentation pool 1, and an electric control valve 15 is provided inside the two drainage pipes 5. The rear side of the distributing pool 2 is open. The outer surfaces of both sides of the distributing pool 2 are provided with a slide groove 8 near the rear edge. The rear side of the distributing pool 2 is slidingly sealed and fitted with a protective plate 7. Both sides of the protective plate 7 extend and slide and engage in the interior of the slide groove 8. A rotating shaft 13 is rotatably provided between the inner walls of both sides of the sedimentation pool 1, and a plurality of stirring blades 14 are equidistantly fixed on the outer surface of the rotating shaft 13. A motor 9 is fixed on one side of the sedimentation pool 1, and the output end of the motor 9 is fixed to one end of the rotating shaft 13.

[0020] The effect achieved is that the flocculant is first placed inside the trough 32, and the water flow for washing the magnetic ore is preliminarily filtered through the filter plate 6 in the distribution pool 2 to separate large particles of impurities. The water flow containing fine particles is transported to the inside of the sedimentation pool 1 through the drain pipe 5. The liquid level inside the sedimentation pool 1 will gradually rise with the injection of water flow, and the rising liquid level will trigger the feedback component to work. When the feedback component works, it will gradually trigger the discharge component to work. After the discharge component sends the flocculant into the sedimentation pool 1, it will trigger the motor 9 to work and mix it. At this time, the liquid level continues to rise until the discharge component triggers the reset delay switch 40 to close the electric control valve 15, cut off the drain pipe 5, and at the same time release the limit of the pull-out plate 11 by the limit component. The sewage mixed with flocculant inside the sedimentation pool 1 can be discharged after static sedimentation.

[0021] like Figure 4 、 Figure 5 、 Figure 6 and Figure 7The feedback assembly shown includes multiple lifting blocks 23, which are correspondingly slidably arranged between the inner walls on both sides of the lifting groove 22. The top and the middle of the front side of the lifting block 23 are inclined, and there is a vertical plane between the two inclined parts. The front sides of the multiple lifting blocks 23 are fixed with bending rods 24 near the bottom edge, and the bottoms of the multiple bending rods 24 are bent and extended to the interior of the sedimentation tank 1. Floating blocks 25 are fixed between the bottoms of the multiple bending rods 24. The floating blocks 25 are located inside the sedimentation tank 1. The lifting block 23 is located directly below the recess 26, and the inclined surface on the lifting block 23 is opposite to the bevel 31.

[0022] The effect achieved is that when the water flow inside the sedimentation tank 1 rises, it will drive the floating block 25 to slide upward, and when the floating block 25 moves upward, it will drive the lifting block 23 to slide upward. When the lifting block 23 rises to the point where the top inclined surface contacts the bevel 31, the discharge assembly can be triggered to discharge the flocculant into the interior of the sedimentation tank 1, and the motor 9 is triggered to work. At this time, the drain pipe 5 continues to inject water into the sedimentation tank 1. When the floating block 25 continues to rise, it will drive the lifting block 23 to continue to slide upward. At this time, one end of the reciprocating plate 29 will slide on the vertical transition surface between the top inclined surface of the lifting block 23 and the inclined surface of the front middle part, so the reciprocating plate 29 does not slide at this time. When the lifting block 23 slides upward to the point where the bevel 31 and the inclined surface of the middle part are in contact with each other, the reciprocating plate 29 will be further pushed. At this time, the discharge assembly is cut off, the motor 9 stops working, the limit assembly releases the limit, and at the same time touches the reset delay switch 40 to close the electric control valve 15, thereby cutting off the drain pipe 5.

[0023] like Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8As shown, the blanking assembly includes a reciprocating plate 29, a notch 26 is provided on one side of the blanking plate 10 near the bottom edge, the notch 26 is located just above the jacking slot 22, a reciprocating slot 27 is provided inside the blanking plate 10 near the bottom edge, one end of the reciprocating slot 27 passes through the inside of the notch 26, a material slot 32 is provided on the top of the blanking plate 10, a plurality of blanking ports 28 that pass through to the bottom of the blanking plate 10 are equidistantly provided on the inner bottom surface of the material slot 32, and the plurality of blanking ports 28 all correspond to and penetrate the reciprocating slot 27, the reciprocating plate 29 slides between the inner walls of the reciprocating slot 27, a plurality of bridging holes 30 that pass through to the bottom are equidistantly provided on the top of the reciprocating plate 29, and the plurality of bridging holes 30 all correspond to and communicate with the blanking ports 28, one end of the reciprocating plate 29 extends to the inside of the notch 26, and the bottom of the reciprocating plate 29 A bevel 31 is provided at one end of the portion, and a hexagonal cavity 33 is provided inside the blanking plate 10 near the edge of the other side. A hexagonal plate 35 is slidably arranged between the inner walls of the hexagonal cavity 33, and a reset spring 34 is fixed to one side of the hexagonal plate 35. One end of the reset spring 34 is fixed to one inner wall of the hexagonal cavity 33. A copper bar 36 is provided between the two sides of the hexagonal plate 35. Copper sheets 37 are provided on both inner walls of the hexagonal cavity 33. Both ends of the copper bar 36 correspond to and slide in contact with the outer surfaces of the two copper sheets 37. The other end of the reciprocating plate 29 slides through the interior of the hexagonal cavity 33 and is fixed on the hexagonal plate 35. A reset delay switch 40 is provided in the middle of the internal top surface of the hexagonal cavity 33. The reset delay switch 40 is electrically connected to the electric control valve 15, and the two copper sheets 37 are electrically connected to the motor 9.

[0024] The effect achieved is that the top inclined surface and the middle inclined surface of the lifting block 23 are sequentially fitted with the bevel 31, so that the reciprocating plate 29 can be pushed to one side in turn. When the top inclined surface of the lifting block 23 contacts the bevel 31 at one end of the reciprocating plate 29, the reciprocating plate 29 will be pushed to one side, so that the bridge hole 30 is opposite to the discharge port 28. At this time, the flocculant inside the trough 32 can be discharged into the interior of the sedimentation tank 1 through the discharge port 28. At this time, the copper bar 36 and the two copper sheets 37 are fitted with each other to start the motor 9, and the motor 9 drives the rotating shaft 13 and the stirring blade 14 to rotate, thereby adjusting the water flow inside the sedimentation tank 1. After mixing and stirring with the flocculant, as the drain pipe 5 continues to inject water into the sedimentation tank 1, the jacking block 23 will gradually slide up, and when one end of the reciprocating plate 29 is located on the vertical transition surface between the top slope of the jacking block 23 and the slope of the middle part of the front side, the above-mentioned working state will still be maintained until the bevel 31 at one end of the reciprocating plate 29 fits with the slope in the middle of the jacking block 23, the reciprocating plate 29 will be further pushed to one side. At this time, the bridging hole 30 is offset from the discharge port 28, so that the discharge port 28 is cut off, and at this time the hexagonal plate 35 will press the reset delay switch 40 to close the electric control valve 15, thereby cutting off the drain pipe 5.

[0025] like Figure 4 、 Figure 5、 Figure 7 and Figure 9 As shown, the limit assembly includes a slide bar 20, which is slidably connected between the inner walls of the rectangular slide cavity 19, and the top of the slide bar 20 extends to the inside of the jacking groove 22 and is fixed to the bottom of the jacking block 23. The inner bottom surface of the sedimentation pool 1 is provided with a discharge port 16, and the rear side of the sedimentation pool 1 is provided with a pull-out port 12, and the pull-out port 12 is connected to the discharge port 16. The inner bottom surface of the pull-out port 12 is located directly below the discharge port 16 and is provided with a guide groove 17. One end of the guide groove 17 passes through the front side of the sedimentation pool 1 and is connected to the diversion channel 4. They are interconnected, and a pull-out plate 11 is slidably arranged between the inner walls of the pull-out opening 12. A through opening 18 is provided on the top of the pull-out plate 11, which extends to the bottom. The discharge port 16 is connected with the guide groove 17 through the through opening 18. Both sides of the pull-out opening 12 are interconnected with the rectangular sliding cavity 19 near the two sides of the sedimentation tank 1. Guide bayonet 39 is provided on both sides of the pull-out plate 11, and the two slides 20 are slidably engaged between the inner walls on both sides of the guide bayonet 39. Side opening 38 is provided on one side of the two slides 20 near the bottom edge.

[0026] The effect achieved is that as the lifting block 23 slides upward, the slide bar 20 will be synchronously driven to slide upward inside the rectangular slide cavity 19. Before the lifting block 23 slides to the working state where the blanking component triggers the reset delay switch 40 to close the electric control valve 15 and then cuts off the drain pipe 5, the side port 38 on the slide bar 20 is always below the pull-out plate 11, and the guide bayonet 39 on the pull-out plate 11 is slidably engaged with the slide bar 20, thereby limiting the pull-out plate 11 and preventing the pull-out plate 11 from being pulled outward. When the lifting block 23 slides to the working state where the blanking component triggers the reset delay switch 40 to close the electric control valve 15, the side port 38 on the slide bar 20 slides to the position opposite to the guide bayonet 39, thereby connecting the guide bayonet 39 to the pull-out plate 11. The sliding bars 20 are in restrained contact, and the pull-out plate 11 can be pulled outward at this time. When pulling, the discharge port 16 and the guide groove 17 are connected to each other through the through-hole 18, so that the water flow inside the sedimentation tank 1 can be discharged. After the water flow is discharged, since the pull-out plate 11 is in a pulled-out state at this time, the constraint between the pull-out plate 11 and the side port 38 can prevent the sliding bar 20 from resetting, and prevent the unloading component and the feedback component from working during the drainage process. After the pull-out plate 11 is subsequently reset, the unloading component and the feedback component can be reset instantly. At the same time, due to the delay effect of the reset delay switch 40, the electric control valve 15 will not open instantly, thereby ensuring that the unloading component and the feedback component will be opened and work again after they are completely reset.

[0027] Working principle: When using this device, first put the flocculant inside the trough 32, and use the filter plate 6 in the distribution pool 2 to preliminarily filter the water flow for washing the magnetic separation, so that large particles of impurities are separated, and the water flow containing fine particles is transported to the inside of the sedimentation pool 1 through the drain pipe 5. When the water flow inside the sedimentation pool 1 rises, it will drive the floating block 25 to slide upward. When the floating block 25 moves upward, it will drive the lifting block 23 to slide upward. When the lifting block 23 rises to the top inclined surface and contacts the bevel 31, the reciprocating plate 29 is pushed to one side so that the bridge hole 30 is opposite to the discharge port 28. At this time, the flocculant inside the trough 32 can be discharged into the interior of the sedimentation pool 1 through the discharge port 28. At this time, the copper bar 36 and the two copper sheets 3 7 fit together to start the motor 9, and the motor 9 drives the rotating shaft 13 and the stirring blade 14 to rotate, so that the water flow and flocculant inside the sedimentation tank 1 are mixed and stirred. Since the drain pipe 5 continues to inject water into the sedimentation tank 1, the jacking block 23 will gradually slide up, and when one end of the reciprocating plate 29 is located on the vertical transition surface between the top inclined surface of the jacking block 23 and the inclined surface in the middle part of the front side, the above-mentioned working state will still be maintained until the bevel 31 at one end of the reciprocating plate 29 fits together with the inclined surface in the middle of the jacking block 23, which will push the reciprocating plate 29 further to one side. At this time, the bridging hole 30 is offset relative to the discharge port 28, so that the discharge port 28 is cut off, and at this time the hexagonal plate 35 will press the reset delay switch 40 to close the electric control valve 15, and the discharge port 28 will be cut off. When the drain pipe 5 is cut off, the upward sliding of the lifting block 23 will synchronously drive the slide bar 20 to slide upward inside the rectangular slide cavity 19. Before the lifting block 23 slides to the working state where the blanking component triggers the reset delay switch 40 to close the electric control valve 15 and then cuts off the drain pipe 5, the side opening 38 on the slide bar 20 is always under the pull-out plate 11, and the guide bayonet 39 on the pull-out plate 11 is slidably engaged with the slide bar 20, thereby limiting the pull-out plate 11 and preventing the pull-out plate 11 from being pulled outward. When the lifting block 23 slides to the working state where the blanking component triggers the reset delay switch 40 to close the electric control valve 15, the side opening 38 on the slide bar 20 slides to the position opposite to the guide bayonet 39, thereby The sliding bars 20 are in restrained contact, and the pull-out plate 11 can be pulled outward at this time. When pulling, the discharge port 16 and the guide groove 17 are connected to each other through the through-hole 18, so that the water flow inside the sedimentation tank 1 can be discharged. After the water flow is discharged, since the pull-out plate 11 is in a pulled-out state at this time, the constraint between the pull-out plate 11 and the side port 38 can prevent the sliding bar 20 from resetting, and prevent the unloading component and the feedback component from working during the drainage process. After the pull-out plate 11 is subsequently reset, the unloading component and the feedback component can be reset instantly. At the same time, due to the delay effect of the reset delay switch 40, the electric control valve 15 will not open instantly, thereby ensuring that the unloading component and the feedback component will be opened and work again after they are completely reset.
