Description

Technical Field

[0001] The utility model belongs to the technical field of iron concentrate purification devices. Specifically, it particularly relates to a purification device for processing iron concentrate tailings. Background Art

[0002] Iron ore is processed through crushing, grinding, ore dressing, etc. into ore powder called iron concentrate. Iron concentrate is the main raw material for pellets. However, at this time, silicon is still contained inside the iron concentrate. The presence of silicon easily causes the overall melting point and melting temperature of the iron concentrate to be relatively high, making the melting process of the iron concentrate difficult. At the same time, silicon impurities will affect the subsequent processing technology of the iron concentrate. Therefore, it is necessary to perform desiliconization treatment on the iron concentrate.

[0003] A purification device for iron concentrate is disclosed in Chinese Patent Network CN220610794U, which includes a purification barrel housing. The lower flange of the purification barrel housing is connected with an electric valve. The middle position inside the purification barrel housing is pivotally connected with a hollow insulating column. It is characterized in that adsorption stirring blades are respectively installed on the left and right sides of the hollow insulating column, a rotating power supply seat is installed on the upper part of the hollow insulating column, a driven bevel gear is bolted and fixed on the upper outer side of the hollow insulating column, a driving motor is bolted and installed on the upper right side of the purification barrel housing, and a driving bevel gear is key-connected to the left side of the output shaft of the driving motor.

[0004] When discharging the purified iron concentrate from the inside of the purification barrel housing, since the iron concentrate as a whole is relatively wet, part of the purified iron concentrate is likely to adhere to the adsorption stirring blades. Moreover, since the adsorption stirring blades are inside the purification barrel housing, a large amount of water is required to wash the iron concentrate on the adsorption stirring blades and make it detach from the adsorption stirring blades. This setting easily causes waste of water resources when discharging the purified iron concentrate from the inside of the purification barrel housing. At the same time, a subsequent filtering process needs to be added to filter out the iron concentrate in the water, which is likely to affect the production efficiency during the purification of the iron concentrate.

[0005] Regarding the problems in the related technology, no effective solution has been proposed yet. Summary of the Utility Model

[0006] Regarding the problems in the related technology, the utility model proposes a purification device for processing iron concentrate tailings to overcome the above-mentioned technical problems existing in the existing related technology.

[0007] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0008] The utility model relates to a purification device for processing iron concentrate tailings, which comprises a purification cylinder. A cylinder cover is fixedly installed at the top of the purification cylinder. A stirring and adsorbing assembly is arranged inside the purification cylinder. A lifting and blowing assembly is arranged inside the purification cylinder. A wind transportation assembly is fixedly connected to the top of the lifting and blowing assembly. A guiding and resetting assembly is arranged outside the wind transportation assembly. A positioning assembly is arranged at the driving end of the stirring and adsorbing assembly.

[0009] Further, the stirring and adsorbing assembly comprises a hollow tube which is rotatably connected to the cylinder cover. A stirring and adsorbing roller is arranged on the outer surface of the hollow tube. A bracket is fixedly installed at the top of the cylinder cover. A motor is fixedly installed inside the bracket. The output end of the motor is fixedly connected with a driving gear. A driven gear is meshed on the outer surface of the driving gear. The driven gear is fixedly connected with the hollow tube.

[0010] Further, the lifting and blowing assembly comprises a hydraulic cylinder which is fixedly installed at the top of the cylinder cover. The output end of the hydraulic cylinder penetrates through the cylinder cover and is fixedly connected with a hollow flow dividing ring. A diversion frame is fixedly connected to the inner wall of the hollow flow dividing ring corresponding to the stirring and adsorbing roller. Spray heads are arranged on the inner wall of the diversion frame and the bottom of the hollow flow dividing ring.

[0011] Further, the wind transportation assembly comprises an installation frame. An exhaust fan is fixedly installed at the top of the installation frame. A telescopic pipe is fixedly installed at the air outlet end of the exhaust fan. A transportation pipe is fixedly connected to the top of the telescopic pipe. A connection hole is formed in the top of the cylinder cover. One end of the transportation pipe is fixedly connected with the hollow flow dividing ring through the connection hole.

[0012] Further, the guiding and resetting assembly comprises a guiding rod. The bottom end of the guiding rod is fixedly connected to the top of the installation frame. A guiding ring is movably connected to the outer surface of the guiding rod. The guiding ring is fixedly connected with the transportation pipe. A reset spring is fixedly connected between the guiding ring and the installation frame. The top end of the guiding rod is fixedly connected with a guiding hollow plate. The transportation pipe is movably connected with the guiding hollow plate.

[0013] Further, the guiding and resetting assembly further comprises a guiding frame which is fixedly installed at the top of the cylinder cover. A guiding roller is rotatably connected to the inner wall of the guiding frame. The transportation pipe is located between the guiding roller and the inner wall of the guiding frame.

[0014] Further, the positioning assembly comprises a positioning block which is fixedly connected to the top of the driven gear. A connecting seat is fixedly connected to the top of the cylinder cover. A limiting rod is rotatably connected inside the connecting seat. The limiting rod is in contact with one side of the positioning block.

[0015] The utility model has the following beneficial effects:

[0016] 1. The utility model can blow the iron concentrate adsorbed on the stirring and adsorbing component through the lifting and blowing component of the wind power transportation component. At the same time, the lifting and blowing component can move up and down inside the purification cylinder, so that the iron concentrate adsorbed on all the stirring ends of the stirring and adsorbing component can be cleaned. The whole cleaning process is mainly completed by wind power, so that the iron concentrate discharged from the inside of the purification cylinder can be directly collected. The above setting makes it unnecessary to waste a large amount of water resources when cleaning the iron concentrate on the stirring and adsorbing component, and it is also unnecessary to filter the iron concentrate from the water again later, thus improving the working efficiency when purifying the iron concentrate.

[0017] 2. When the hollow shunt ring moves downward, it can pull the transportation pipe. At this time, the transportation pipe can pull the return spring through the guide ring and make the guide ring move upward along with the transportation pipe under the guidance of the guide rod. When the hollow shunt ring moves upward, the pulling force of the transportation pipe on the guide ring decreases. At this time, the return spring can pull the guide ring downward. At this time, the transportation pipe can continuously move out of the inside of the purification cylinder under the pulling of the guide ring. The above setting makes the transportation pipe continuously move out of the purification cylinder as the hollow shunt ring moves upward continuously, thus avoiding the phenomenon that the transportation pipe accumulates on the hollow shunt ring and hinders the reset of the hollow shunt ring when the hollow shunt ring moves upward and resets.

[0018] Of course, it is not necessary for any product implementing the utility model to achieve all the above advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the utility model without creative efforts shall fall within the protection scope of the utility model.

[0031] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc. indicating orientation or positional relationships are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the utility model.

[0032] Please refer to Figures 1 - 8As shown in the figure, the utility model is a purification device for iron concentrate tailings processing, including a purification cylinder 1. A cylinder cover 2 is fixedly installed at the top of the purification cylinder 1. A stirring and adsorption assembly 3 is arranged inside the purification cylinder 1. A lifting and blowing assembly 4 is arranged inside the purification cylinder 1. The top of the lifting and blowing assembly 4 is fixedly connected to a wind transportation assembly 5. A guiding and resetting assembly 6 is arranged outside the wind transportation assembly 5. A positioning assembly 7 is arranged at the driving end of the stirring and adsorption assembly 3.

[0033] After the stirring and adsorption assembly 3 completes the adsorption of the purified iron concentrate and discharges the solution from the inside of the purification cylinder 1, the stirring and adsorption assembly 3 is rotated to a suitable position through the positioning assembly 7. Then, the lifting and blowing assembly 4 starts to move downward inside the purification cylinder 1. At this time, the wind transportation assembly 5 transports air flow to the lifting and blowing assembly 4 and enables the lifting and blowing assembly 4 to blow the iron concentrate adhered to the stirring and adsorption assembly 3 downward, so that the iron concentrate adhered to the stirring and adsorption assembly 3 can be separated from the stirring and adsorption assembly 3 and directly fall outside the purification cylinder 1.

[0034] Through the wind transportation assembly 5, the lifting and blowing assembly 4 can blow the iron concentrate adsorbed on the stirring and adsorption assembly 3. At the same time, the lifting and blowing assembly 4 can move up and down inside the purification cylinder 1, so that the iron concentrate adsorbed on all the stirring ends of the stirring and adsorption assembly 3 can be cleaned. The whole cleaning process is mainly completed by wind power, so that the iron concentrate discharged from the inside of the purification cylinder 1 can be directly collected. The above settings make it unnecessary to waste a large amount of water resources when cleaning the iron concentrate on the stirring and adsorption assembly 3, and it is also unnecessary to filter the iron concentrate from the water again later, thus improving the working efficiency of purifying the iron concentrate.

[0035] In one embodiment, for the above-mentioned stirring and adsorption assembly 3, the stirring and adsorption assembly 3 includes a hollow tube 301. The hollow tube 301 is rotatably connected to the cylinder cover 2. Stirring and adsorption rollers 302 are arranged on the outer surface of the hollow tube 301. A bracket 303 is fixedly installed at the top of the cylinder cover 2. A motor 304 is fixedly installed inside the bracket 303. The output end of the motor 304 is fixedly connected to a driving gear 305. A driven gear 306 is engaged with the outer surface of the driving gear 305. The driven gear 306 is fixedly connected to the hollow tube 301.

[0036] After putting the iron concentrate powder to be purified and the alkaline solution into the interior of the purification cylinder 1, the motor 304 drives the driving gear 305 to rotate. The rotating driving gear 305 drives the hollow tube 301 to rotate through the driven gear 306. The hollow tube 301 drives the stirring and adsorbing roller 302 to rotate inside the purification cylinder 1, enabling the silicon in the iron concentrate powder to fully react with the alkaline solution. At the same time, since an electromagnet is installed inside the stirring and adsorbing roller 302 and a conductive slip ring is installed at the top of the hollow tube 301, the external power supply can supply power to the rotating stirring and adsorbing roller 302 through the conductive slip ring and the hollow tube 301, enabling the stirring and adsorbing roller 302 to adsorb the iron concentrate powder in the solution. The entire purification operation is the same as that in the comparative document.

[0037] In one embodiment, for the above-mentioned lifting and blowing assembly 4, the lifting and blowing assembly 4 includes a hydraulic cylinder 401. The hydraulic cylinder 401 is fixedly installed on the top of the cylinder cover 2. The output end of the hydraulic cylinder 401 penetrates through the cylinder cover 2 and is fixedly connected to a hollow shunt ring 402. A flow guide frame 403 is fixedly connected to the inner wall of the hollow shunt ring 402 corresponding to the stirring and adsorbing roller 302. Spray nozzles 404 are provided on the inner wall of the flow guide frame 403 and the bottom of the hollow shunt ring 402.

[0038] After discharging the alkaline liquid and the compound produced by the reaction of the alkaline liquid with silicon from the interior of the purification cylinder 1, the electromagnet inside the stirring and adsorbing roller 302 is powered off. Next, the hydraulic cylinder 401 is driven, so that the hydraulic cylinder 401 drives the flow guide frame 403 to move downward through the hollow shunt ring 402. At this time, the stirring and adsorbing roller 302 is on one side of the inner wall of the flow guide frame 403, enabling the spray nozzles 404 provided on the inner wall of the flow guide frame 403 to blow the iron concentrate powder adhered to the stirring and adsorbing roller 302, and enabling the iron concentrate powder to fall off the stirring and adsorbing roller 302 under the blowing of the air flow. At the same time, the spray nozzles 404 at the bottom of the hollow shunt ring 402 prevent the fallen iron concentrate powder from adhering to the interior of the purification cylinder 1 again. At the same time, since the spray nozzles 404 provided on the inner wall of the flow guide frame 403 are inclined, the air flow sprayed by the spray nozzles 404 can blow obliquely onto the stirring and adsorbing roller 302, resulting in a better effect when cleaning the iron concentrate powder adsorbed on the stirring and adsorbing roller 302.

[0039] In one embodiment, for the above-mentioned wind transportation assembly 5, the wind transportation assembly 5 includes a mounting frame 501. A suction fan 502 is fixedly installed on the top of the mounting frame 501. The air outlet end of the suction fan 502 is fixedly installed with a telescopic tube 503. The top of the telescopic tube 503 is fixedly connected to a transportation tube 504. A connection hole 505 is opened on the top of the cylinder cover 2. One end of the transportation tube 504 is fixedly connected to the hollow shunt ring 402 through the connection hole 505.

[0040] The exhaust fan 502 extracts the air from the outside. The extracted air can flow into the interior of the hollow diversion ring 402 under the guidance of the telescopic pipe 503 and the transport pipe 504. At the same time, the air flow inside the hollow diversion ring 402 is diverted into the interior of the diversion frame 403, so that the nozzles 404 on the bottom of the hollow diversion ring 402 and the inner wall of the diversion frame 403 spray out the extracted air. The setting of the telescopic pipe 503 enables the telescopic pipe 503 to expand and contract when the hollow diversion ring 402 moves inside the purification cylinder 1, so that the air flow extracted by the exhaust fan 502 can normally be transported into the interior of the hollow diversion ring 402 through the telescopic pipe 503 and the transport pipe 504. At the same time, a filter screen is provided at the air extraction end of the exhaust fan 502, and this setting enables the exhaust fan 502 to filter the impurities carried in the air flow when extracting the air flow.

[0041] In one embodiment, for the above-mentioned guiding and resetting assembly 6, the guiding and resetting assembly 6 includes a guiding rod 601. The bottom end of the guiding rod 601 is fixedly connected to the top of the mounting frame 501. A guiding ring 602 is movably connected to the outer surface of the guiding rod 601. The guiding ring 602 is fixedly connected to the transport pipe 504. A reset spring 603 is fixedly connected between the guiding ring 602 and the mounting frame 501. The top end of the guiding rod 601 is fixedly connected to a guiding hollow plate 604. The transport pipe 504 is movably connected to the guiding hollow plate 604.

[0042] When the hollow diversion ring 402 moves downward, it can pull the transport pipe 504. At this time, the transport pipe 504 can pull the reset spring 603 through the guiding ring 602 and make the guiding ring 602 move upward along with the transport pipe 504 under the guidance of the guiding rod 601. And at this time, under the pull of the transport pipe 504, the telescopic pipe 503 starts to expand and contract. When the hollow diversion ring 402 moves upward, the pulling force of the transport pipe 504 on the guiding ring 602 decreases. At this time, the reset spring 603 can pull the guiding ring 602 downward. At this time, the transport pipe 504 can continuously move out of the interior of the purification cylinder 1 under the pull of the guiding ring 602. The above setting enables the transport pipe 504 to continuously move out of the purification cylinder 1 as the hollow diversion ring 402 continuously moves upward, thus avoiding the phenomenon that the transport pipe 504 accumulates on the hollow diversion ring 402 and hinders the reset of the hollow diversion ring 402 when the hollow diversion ring 402 moves upward and resets.

[0043] In one embodiment, for the above-mentioned guiding and resetting assembly 6, the guiding and resetting assembly 6 further includes a guiding frame 605. The guiding frame 605 is fixedly installed on the top of the cylinder cover 2. A guiding roller 606 is rotatably connected to the inner wall of the guiding frame 605. The conveying pipe 504 is located between the guiding roller 606 and the inner wall of the guiding frame 605.

[0044] When the hollow shunt ring 402 drives the conveying pipe 504 to move inside the guiding frame 605, the guiding roller 606 rotates together when the conveying pipe 504 moves. This setting enables the conveying pipe 504 not to directly contact the cylinder cover 2 at the corner of the cylinder cover 2, so that the conveying pipe 504 is not easily worn due to the cylinder cover 2 when moving.

[0045] In one embodiment, for the above-mentioned positioning assembly 7, the positioning assembly 7 includes a positioning block 701. The positioning block 701 is fixedly connected to the top of the driven gear 306. A connecting seat 702 is fixedly connected to the top of the cylinder cover 2. A limiting rod 703 is rotatably connected to the inside of the connecting seat 702. The limiting rod 703 is in contact with one side of the positioning block 701.

[0046] When cleaning the iron ore powder adsorbed on the stirring and adsorbing roller 302, directly rotate the limiting rod 703 and make the limiting rod 703 located on the upper side of the driven gear 306. The motor 304 is selected as a motor that can stop when encountering resistance. (The principle of this motor is based on the design of the motor control circuit. When the motor is affected by an external resistance and the load of the motor is too large, the current inside the circuit will increase instantaneously. An overcurrent protection device is usually set in the circuit design. When the current exceeds the limit value, the power supply inside the circuit will be cut off, and the motor will stop working immediately to avoid further damage.) At this time, start the motor 304 and make the motor 304 drive the hollow pipe 301 to rotate through the driving gear 305 and the driven gear 306. When the positioning block 701 on the driven gear 306 contacts the limiting rod 703, the driven gear 306 cannot rotate. At this time, the motor 304 is affected by the resistance and stops working. At the same time, multiple groups of stirring and adsorbing rollers 302 are directly located under the diversion frame 403. This setting enables the lifting and blowing assembly 4 to lift normally and complete the cleaning of the iron ore powder.

[0047] Through the above technical solutions: 1. By means of the wind transportation component 5 lifting the blowing component 4, the iron concentrate adsorbed on the stirring and adsorption component 3 can be blown, and at the same time, the lifting and blowing component 4 can move up and down inside the purification cylinder 1, so that the iron concentrate adsorbed on all the stirring ends of the stirring and adsorption component 3 can be cleaned. The whole cleaning process is mainly completed by wind power, so that the iron concentrate discharged from the inside of the purification cylinder 1 can be directly collected. The above setting makes it unnecessary to waste a large amount of water resources when cleaning the iron concentrate on the stirring and adsorption component 3, and it is also unnecessary to filter the iron concentrate from water again later, thus improving the working efficiency when purifying the iron concentrate; 2. When the hollow shunt ring 402 moves downward, it can pull the transportation pipe 504. At this time, the transportation pipe 504 can pull the return spring 603 through the guide ring 602 and make the guide ring 602 move upward along with the transportation pipe 504 under the guidance of the guide rod 601. When the hollow shunt ring 402 moves upward, the pulling force of the transportation pipe 504 on the guide ring 602 decreases. At this time, the return spring 603 can pull the guide ring 602 downward. At this time, the transportation pipe 504 can continuously move out of the inside of the purification cylinder 1 under the pulling of the guide ring 602. The above setting enables the transportation pipe 504 to continuously move out of the purification cylinder 1 as the hollow shunt ring 402 moves upward continuously, thus avoiding the phenomenon that the transportation pipe 504 accumulates on the hollow shunt ring 402 and hinders the reset of the hollow shunt ring 402 when the hollow shunt ring 402 moves upward and resets.
