Description

Technical Field

[0001] This invention relates to the field of mineral processing equipment technology, and more specifically, to a vanadium-titanium magnetic concentrate magnetic gravity coupling separation device for removing titanium impurities. Background Technology

[0002] Vanadium-titanium magnetite concentrate is a powder material obtained after beneficiation of vanadium-titanium magnetite. It mainly contains various metallic elements such as iron, vanadium, and titanium. In actual production, due to the complex intergrowth relationship of vanadium-titanium magnetite, fine-grained ilmenite is often mixed in the iron concentrate in the form of intergrowths or inclusions, resulting in a high titanium impurity content in the final iron concentrate product. This affects the grade of the iron concentrate and the subsequent smelting efficiency. Therefore, in order to improve the purity of the iron concentrate, titanium impurities need to be removed.

[0003] The existing method for removing titanium impurities from iron concentrate mainly uses flotation for titanium removal. However, flotation requires the addition of various separation reagents, resulting in high overall separation costs. At the same time, there are environmental pressures such as wastewater treatment, which further increases the cost of supporting tailings water treatment equipment.

[0004] Based on this, a vanadium-titanium magnet powder magnetic gravity coupling separation device for removing titanium impurities is proposed. Summary of the Invention

[0005] The main objective of this invention is to provide a vanadium-titanium magnet powder magnetic gravity coupling titanium impurity removal and sorting device to overcome the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides a vanadium-titanium magnet powder magnetic gravity coupling titanium removal impurity sorting device, including a sorting frame, a fixing frame fixedly installed in the middle of the lower surface of the sorting frame, electric telescopic rods fixedly installed on both sides of the middle of the lower surface of the fixing frame, guide plates fixedly installed at intervals on the inner bottom surface of the sorting frame to form a guide flow path, and four sets of settling tanks opened along the guide flow path on the inner bottom surface of the sorting frame. Both sides of the lower surface of the settling tank are connected and installed with diverter cylinders. The diverter cylinders on the same side are connected by a conveying pipe. A hollow sorting cylinder is movably sealed and inserted into the upper part of the inner surface of the diverter cylinder. A piston rod is fixedly installed in the middle of the lower surface of the sorting cylinder. The other end of the piston rod movably seals and extends outward through the diverter cylinder. The other end of the piston rod is fixedly installed with a connecting frame. The output end of the electric telescopic rod is fixedly connected to the lower surface of the connecting frame. An electromagnet block is embedded and fixed in the inner bottom surface of the sorting cylinder.

[0007] As a further improvement of the present invention, a frame cover is installed on one side of the upper surface of the sorting frame by means of a hinge, a feed hopper is connected to the middle of the rear end of the outer surface of the sorting frame, a discharge hopper is connected to the middle of the front end of the outer surface of the sorting frame, a discharge port is opened in the middle of the inner bottom surface of the discharge hopper, and a sealing nut is spirally inserted into the inner surface of the discharge port of the discharge hopper.

[0008] As a further improvement of the present invention, the intervals between several guide plates on the adjacent side are connected to form a zigzag guide path. Stirring rods are sealed and rotatably installed on both sides of the rear end of the inner surface of the sorting frame. The other end of each stirring rod passes through the guide plate. Stirring blades are fixedly installed on the outer surface of the stirring rod at the connection point of the guide path. Motors are fixedly installed on both sides of the rear end of the outer surface of the sorting frame. The output end of the motor is connected to the stirring rod.

[0009] As a further improvement of the present invention, a set of settling tanks includes a first settling tank, a second settling tank, and a third settling tank. The first settling tank, the second settling tank, and the third settling tank are sequentially arranged at intervals on the adjacent side of the outer surface of the guide plate. The first settling tank, the second settling tank, and the third settling tank are all trapezoidal in shape, wider at the top and narrower at the bottom. The depth of the first settling tank, the second settling tank, and the third settling tank increases sequentially. The inner surfaces of the first settling tank, the second settling tank, and the third settling tank are all smoothly arc-shaped.

[0010] As a further improvement of the present invention, the sorting cylinder extends into the settling tank group, and a number of sealing rings are fixedly installed on the outer surface of the sorting cylinder. The sealing rings are in elastic contact with the inner ring surface of the diverting cylinder, and a flow-gathering port is opened through the middle of both sides of the outer surface of the sorting cylinder corresponding to the conveying pipe.

[0011] As a further improvement of the present invention, a number of controllers are fixedly installed at intervals on the lower surface of the connecting frame, the number of controllers are electrically connected in series, and the controllers are connected to the electromagnet block by connecting wires through the connecting frame and the piston rod.

[0012] The beneficial effects of this invention are: This invention combines magnetic separation structure with gravity sedimentation separation structure, making full use of the dual differences in magnetism and density between iron concentrate and titanium impurities to achieve separation effect, reduce separation cost while ensuring separation accuracy, effectively remove and reduce the content of titanium impurities in iron concentrate, and improve the purity of finished iron concentrate. This invention alternates between magnetic separation and gravity settling structures, causing the slurry material to undergo multiple wave separations within the separation channel. This enhances the separation effect between iron concentrate and titanium impurities, and is particularly effective in removing fine-grained titanium impurities. This invention enables the separate discharge of iron concentrate and titanium impurities during the sorting process, thereby avoiding the need for separate discharge of each material after the sorting is stopped to prevent material mixing. This facilitates continuous sorting of slurry materials and further improves the processing efficiency of removing titanium impurities from iron concentrate. Attached Figure Description

[0018] To make the objectives and advantages of the present invention clearer, the present invention will be further described below with reference to embodiments; it should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention.

[0019] Please see Figures 1-10 As shown, a vanadium-titanium magnetic powder magnetic gravity coupling titanium impurity removal and sorting device includes a sorting frame 1. A frame cover 101 is movably hinged to one side of the upper surface of the sorting frame 1 via a hinge. A feed hopper 102 is connected to the middle of the rear end of the outer surface of the sorting frame 1. A discharge hopper 103 is connected to the middle of the front end of the outer surface of the sorting frame 1. A discharge port is opened in the middle of the inner bottom surface of the discharge hopper 103. A sealing nut 104 is spirally inserted into the inner surface of the discharge port of the discharge hopper 103. It should be noted that, by using the sorting frame 1 as the sorting carrier of the entire sorting device, the closed sorting of titanium impurities can be achieved when the frame cover 101 is closed. The vanadium-titanium magnetite concentrate slurry can enter the sorting frame 1 from the feed hopper 102, complete the sorting, and then be discharged through the discharge port set in the discharge hopper 103.

[0020] A fixing frame 105 is fixedly installed in the middle of the lower surface of the sorting frame 1, and electric telescopic rods 106 are fixedly installed on both sides of the middle of the lower surface of the fixing frame 105. The inner bottom surface of the sorting frame 1 is fixedly and intermittently equipped with guide plates 107 to form a guide path. The intervals between several guide plates 107 on the side closest to each other are connected to form a zigzag guide path. Both rear ends of the inner surface of the sorting frame 1 are sealed and rotatably inserted with stirring rods 108. The other end of each stirring rod 108 passes through the guide plate 107. Stirring blades are fixedly installed on the outer surface of the stirring rod 108 at the connection point of the guide path. Both rear ends of the outer surface of the sorting frame 1 are fixedly installed with motors 109. The output end of the motors 109 is connected to the stirring rods 108. It should be noted that by constructing a guide flow path by staggeredly setting guide plates 107 in the sorting frame 1, the vanadium-titanium magnetite concentrate slurry entering the sorting frame 1 will flow and be sorted along the guide flow path constructed by the guide plates 107. Since the guide flow path constructed by the guide plates 107 is in the form of a broken line, the slurry will continuously experience turning and collision phenomena during the flow process, so as to improve the dispersion effect of iron concentrate and titanium impurities in it. At the same time, during the flow process, the motor 109 can be started to control the stirring rod 108 to drive the stirring blade to rotate, so as to achieve turbulence and stirring of the slurry, further improving the dispersion effect of iron concentrate and titanium impurities in it when the slurry flows into the settling tank group 2.

[0021] Four sets of settling troughs 2 are provided on the inner bottom surface of the sorting frame 1 along the guide path. Each set of settling troughs 2 includes a first settling trough 201, a second settling trough 202, and a third settling trough 203. The first settling trough 201, the second settling trough 202, and the third settling trough 203 are arranged in a series of intervals on the outer surface of the guide plate 107. The first settling trough 201, the second settling trough 202, and the third settling trough 203 are all arranged in a trapezoidal shape that is wider at the top and narrower at the bottom. The depth of the first settling trough 201, the second settling trough 202, and the third settling trough 203 increases sequentially. The inner surfaces of the first settling trough 201, the second settling trough 202, and the third settling trough 203 are all arranged in a smooth arc shape. It should be noted that the settling tank group 2 is used for the settling and separation of iron concentrate and titanium impurities. Since the density of iron concentrate is greater than that of titanium impurities, the iron concentrate will settle towards the bottom of the slurry during the slurry flow, while the titanium impurities will float towards the top of the slurry. When the iron concentrate is concentrated at the bottom of the slurry, as the slurry continues to flow through the settling tank group 2, the iron concentrate concentrated at the bottom of the slurry will settle into the first settling tank 201, the second settling tank 202 and the third settling tank 203, while the titanium impurities floating at the top of the slurry will continue to flow with the slurry, thus realizing the settling and separation of iron concentrate and titanium impurities. Since the first settling tank 201, the second settling tank 202, and the third settling tank 203 are all trapezoidal in shape with a wider top and a narrower bottom, and the depth of the tank increases sequentially, the settling tank group 2 can form sorting areas with different settling intensities. When the slurry flows to the settling tank group 2, the flow rate is slowed down due to the increase in the depth of the settling tank group 2, so that the iron concentrate has a longer settling path and time, thereby fully completing the settling process and improving the separation effect of titanium impurities. At the same time, the smooth arc-shaped setting of the inner surface of the settling tank group 2 forms a smooth transition guide slope, avoiding the formation of flow dead zones in the settling tank group 2.

[0022] A diversion cylinder 3 is installed on both sides of the middle of the lower surface of the settling tank group 2. A conveying pipe 301 is connected between the diversion cylinders 3 on the same side. A hollow sorting cylinder 4 is installed in the upper part of the inner surface of the diversion cylinder 3. The sorting cylinder 4 extends into the settling tank group 2. Several sets of sealing rings 401 are fixedly installed on the outer surface of the sorting cylinder 4. The sealing rings 401 are in elastic contact with the inner ring surface of the diversion cylinder 3. A flow-gathering port 402 is opened through the middle of both sides of the outer surface of the sorting cylinder 4 corresponding to the conveying pipe 301. A piston rod 403 is fixedly installed in the middle of the lower surface of the sorting cylinder 4. The other end of the piston rod 403 extends outward through the diversion cylinder 3 in a movable seal. A connecting frame 404 is fixedly installed at the other end of the piston rod 403. The output end of the electric telescopic rod 106 is fixedly connected to the lower surface of the connecting frame 404. An electromagnet block 5 is embedded and fixed in the inner bottom surface of the sorting cylinder 4. It should be noted that by setting up the diversion cylinder 3 and the conveying pipe 301 to cooperate in constructing the discharge channel of iron concentrate, and by connecting the end of the conveying pipe 301 at one end of the feed hopper 102 to a water source, the iron concentrate entering the diversion cylinder 3 is flushed and discharged by the water source, while the separated titanium impurities will be discharged along the guide path of the sorting frame 1. This can realize the separation and discharge of iron concentrate and titanium impurities during the sorting process, avoiding the phenomenon of needing to stop the sorting machine to clean and discharge the materials one by one. By inserting a sorting cylinder 4 into the upper part of the diversion cylinder 3, and extending the sorting cylinder 4 into the settling tank group 2, the iron concentrate that has settled into the settling tank group 2 can be magnetically adsorbed by the sorting cylinder 4. Since an electromagnet block 5 is embedded in the inner bottom surface of the sorting cylinder 4, a magnetic force can be generated when the electromagnet block 5 is energized, thereby magnetically drawing the iron concentrate in the settling tank group 2 into the sorting cylinder 4 through the flow-gathering port 402 and adsorbing it onto the electromagnet block 5, thus completing the collection of the settled iron concentrate in the settling tank group 2. In addition, the magnetic force of the electromagnet block 5 can enhance the settling effect of the iron concentrate in the settling tank group 2. When the iron concentrate collected in the sorting cylinder 4 reaches a certain amount, the output end of the electric telescopic rod 106 can be controlled to retract. At this time, the retracted electric telescopic rod 106 can drive the connecting frame 404 to descend synchronously. The descent of the connecting frame 404 can synchronously stretch the sorting cylinder 4 to sink into the diversion cylinder 3 through the piston rod 403. During the sinking process of the sorting cylinder 4, several sealing rings 401 set on its outer ring surface are elastically abutted against the inner ring surface of the diversion cylinder 3, thereby providing a sealing effect to prevent the slurry from flowing into the sorting cylinder 4 on a large scale when the sorting cylinder 4 sinks into the diversion cylinder 3. At the same time, since the sorting cylinder 4 is hollow, it means that its top and bottom are closed, leaving only the flow-gathering ports 402 opened on both sides. Under this condition, when the sorting cylinder 4 is completely sunk into the diversion cylinder 3, the top of the sorting cylinder 4 can block the connection between the diversion cylinder 3 and the settling tank group 2 to prevent the slurry from entering the diversion cylinder 3 due to the gaps created by the sinking of the sorting cylinder 4. When the sorting cylinder 4 has completely settled into the diversion cylinder 3, the water supply connected to the conveying pipe 301 can be turned on. At this time, the water will flow into the diversion cylinder 3 along the conveying pipe 301. Under these circumstances, the electromagnet block 5 can be de-energized. When the electromagnet block 5 is de-energized, its magnetic force disappears, and the iron concentrate adsorbed by it can flow synchronously with the water flow. After passing through several diversion cylinders 3 and conveying pipes 301, it is finally sorted and discharged. During this iron concentrate discharge process, since the settling tank group 2 is equipped with two sets of discharge structures, they can be operated alternately during discharge to ensure that when one set of discharge structures discharges iron concentrate, the other set of discharge structures stably adsorbs iron concentrate, ensuring the continuous sorting effect during the iron concentrate discharge process.

[0023] Several sets of controllers 501 are fixedly installed at intervals on the lower surface of the connecting frame 404. The several sets of controllers 501 are electrically connected in series. The controllers 501 pass through the connecting frame 404 and the piston rod 403 and are electrically connected to the electromagnet block 5 via connecting wires 502. It should be noted that, since the connecting wire 502 passes through the piston rod 403 and the connecting frame 404 to realize the electrical connection between the electromagnet block 5 and the controller 501, the controller 501 can isolate and control the electromagnet block 5, ensuring the effect of power-on and power-off control of the electromagnet block 5. At the same time, if several controllers 501 are connected in series, the effect of synchronous power-on and power-off of the electromagnet block 5 under the same discharge path can be realized, ensuring the stable discharge of iron concentrate.

[0024] In use, the vanadium-titanium magnetite concentrate slurry can first be fed into the sorting frame 1 from the feed hopper 102. The vanadium-titanium magnetite concentrate slurry entering the sorting frame 1 will flow and be sorted along the guide path constructed by the guide plate 107. Since the density of iron concentrate is greater than that of titanium impurities, the iron concentrate will settle towards the bottom of the slurry during the flow of the slurry, while the titanium impurities will float towards the top of the slurry. When the iron concentrate is concentrated at the bottom of the slurry, as the slurry continues to flow through the settling tank group 2, the iron concentrate concentrated at the bottom of the slurry will settle into the first settling tank 201, the second settling tank 202 and the third settling tank 203, while the titanium impurities floating on the top of the slurry will continue to flow with the slurry, thus realizing the settling and sorting of iron concentrate and titanium impurities. When the iron concentrate settles into the settling tank group 2, the electromagnet block 5 is energized to generate magnetic force, thereby magnetically drawing the iron concentrate in the settling tank group 2 into the sorting cylinder 4 through the flow-gathering port 402 and adsorbing it onto the electromagnet block 5, thus completing the collection of the settled iron concentrate in the settling tank group 2. When the iron concentrate collected in the sorting cylinder 4 accumulates to a certain amount, the output end of the electric telescopic rod 106 can be controlled to retract. At this time, the electric telescopic rod 106 in the retracted state can drive the connecting frame 404 to descend synchronously, and the descent of the connecting frame 404 can synchronously stretch the sorting cylinder 4 to sink into the diversion cylinder 3 through the piston rod 403. Secondly, when the sorting cylinder 4 has completely settled into the diversion cylinder 3, the water supply connected to the conveying pipe 301 can be turned on. At this time, the water will flow into the diversion cylinder 3 along the conveying pipe 301. Under these circumstances, the electromagnet block 5 can be de-energized. When the electromagnet block 5 is de-energized, its magnetic force disappears, and the iron concentrate adsorbed by it can be flushed out of the sorting cylinder 4 through the converging port 402 with the water flow and achieve synchronous flow. After passing through several diversion cylinders 3 and conveying pipes 301, the sorting and discharge are finally completed. The separated titanium impurities will be discharged from the discharge hopper 103 along with the slurry along the guide path of the sorting frame 1.

[0025] The above are merely embodiments of the present invention and are not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art.
