Description

Technical Field

[0001] The invention relates to the technical field of ore equipment, and in particular to a multi-stage separation titanium magnetic separator for ilmenite ore. Background Art

[0002] Magnetic separator is a screening equipment used to remove magnetic materials such as iron powder from powdery particles for recycling. After the ore is crushed, screened, magnetically separated and concentrated, the ore is rationally classified and utilized. In the ilmenite screening process, the weak magnetism of ilmenite ore itself is used to screen large pieces of ore. Due to the limitations of flow rate, viscosity and other conditions, the small pieces of stone or powdery ore mixed in it have weak magnetism and are often discharged into the waste under the action of inertia, resulting in a large waste of resources. If the waste is screened for the second time, the entire waste is often put into high-gradient magnetic separators and other equipment for re-screening, and the treatment effect is not good. Even if it is magnetically separated again after sorting, the process is still complicated. As the number of equipment increases, the floor space also increases, resulting in increased energy consumption and a substantial increase in production costs, which is very unfavorable to enterprise production.

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0035] Specific implementation method 1: Combination Figure 1-16 As shown, a multi-stage separation titanium magnetic separator for ilmenite ore is characterized in that it comprises: a machine body 1, in which a cylinder 101, a primary separation part 2, a secondary fine separation part 3, a pushing device 4 and a sedimentation collection part 5 are arranged in sequence in the machine body 1 from the feeding direction; the primary separation part 2 comprises an inclined platform 201 located below the cylinder 101, and an inclined vibration plate 202 and a drainage channel 203 located below the vibration plate 202; the ilmenite ore raw material enters from the top of the machine body 1, passes through the cylinder 101, the primary separation part 2, the secondary fine separation part 3, the pushing device 4 and the sedimentation collection part 5 in sequence, the bulk raw material is magnetically adsorbed by the cylinder 101, the ilmenite ore is separated by the weak magnetism of the ore, and the ordinary ore falls to the primary separation part 2 under the action of inertia, and the ordinary ore is screened again by the vibration force of the vibration plate 202. The small ores and powders mixed in the middle fall through the through holes of the vibrating plate, and fall to the secondary fine separation part 3 through the drainage channel 203. By screening the waste materials, repeated operations are avoided, and the workload of the secondary fine separation part 3 is reduced, thereby improving the efficiency and effect of the second screening. The secondary fine separation part 3 relies on water flow pulses to push the raw materials to contact with the magnetic adsorption part to achieve secondary screening, while achieving the cleaning of the raw materials. In the liquid medium, it is easier to adsorb the powder ores, thereby improving the utilization rate and reducing the waste of resources. Under the action of gravity, the ordinary ores fall to the pushing device 4 and are pushed to the sedimentation collection part 5 for discharge. The overall structure is compact, which improves the utilization rate of resources and effectively avoids the waste of ore. At the same time, it reduces the floor space and the purchase cost of equipment, reduces the burden on enterprises, and meets the needs of mines of different sizes.

[0036] Combination Figure 2 and Figure 3 As shown, the drainage channel 203 includes a first baffle 204 and a second baffle 205 located below; the inclination direction of the first baffle 204 is the same as the discharge direction, and is located below the vibration plate 202; the inclination direction of the second baffle 205 is opposite to the discharge direction; the first baffle 204 and the second baffle 205 are arranged in double layers, and the directions of the two baffles are designed to facilitate the distribution of ore raw materials, while avoiding the situation where the ore falls too high to cause stone collision, causing stone splashing, and inconvenient screening; wherein, two groups of vertically arranged partitions can also be set at the discharge end of the second baffle 205, and the two groups of partitions are staggered with each other, so that the ore raw materials can fall evenly to the secondary fine separation part 3, thereby improving the screening effect.

[0037] Combination Figure 2-4 As shown, the secondary fine separation part 3 includes a power member 301 located on the left side of the body 1 and arranged in multiple groups and a circularly rotating magnetic suction member 302; a directional channel 303 is provided on the power member 301; the magnetic suction member 302 is in a right-angle trapezoidal structure as a whole, and the feeding direction is opposite to the inclined side of the trapezoid, a discharge member 304 is provided above the magnetic suction member 302, and a discharge trough 305 is provided in the middle; the power member 301 generates pulsed water waves, which push the ore raw materials in the water to rush towards the rotating magnetic suction member 302, and the magnetic suction member 302 is used to adsorb the titanium iron powder particles to achieve secondary filtration and collection, while ordinary ore is discharged along the magnetic suction member 302 falls, and multiple groups of power parts 301 are used to form multiple layers of water waves in the water, which push the raw materials to repeatedly contact with the magnetic suction part 302 to ensure the filtering effect. At the same time, the magnetic suction part 302 is an overall right-angle trapezoidal structure and is arranged inverted. The inclined edge contacts the ore, which is convenient for the ore to slide down. At the same time, the water flow is guided to tilt downward, driving different ores to fall faster, thereby improving the processing efficiency. During the clockwise intermittent rotation of the magnetic suction part 302, the magnetic suction screening of the raw materials is completed, and the ore raw materials adsorbed on the magnetic suction part 302 are removed at the top through the discharge part 304, and fall into the discharge trough 305 for discharge, completing the unloading operation;

[0038] The power part 301 can generate jet water flow in stages to disturb the water at the bottom of the body 1 to form water waves to impact the raw materials and contact the magnetic attraction part 302. Compressed air can also be used as the initial energy to generate water waves.

[0039] The discharge part 304 includes a nozzle and a pipeline. The nozzle is vertically downward and is located directly above the discharge chute 305. The magnetic component 302 passes therebetween. The pipeline is connected to external equipment to achieve power transmission. The nozzle can use air or water flow to flush the magnetic component 302, blow or flush the ore material adsorbed on the magnetic component 302, and then discharge it from the discharge chute 305. The structure is stable and convenient, and will not affect other components.

[0040] Among them, a sensor can also be installed at the nozzle to identify the position of the blade 7, and cooperate with the PLC controller to control the conveying part, so as to improve the positioning accuracy of the blade 7 when it stops, ensure that the blade 7 is directly under the nozzle when it stops, and ensure the cleaning effect;

[0041] In a preferred embodiment, a plurality of guide plates 306 are provided in the pointing channel 303, and a fixed distance is provided between the pointing channel 303 and the magnetic component 302; the pointing channel 303 realizes an energy gathering effect to avoid water waves from spreading around and causing insufficient water flow intensity, and the guide plates 306 facilitate the water flow to be guided and distributed, thereby improving the impact effect on the ore, and a certain distance is provided between the pointing channel 303 and the magnetic component 302 to avoid excessive impact force, thereby affecting the adsorption of the magnetic component 302, and at the same time reducing the ore raw materials from falling above the pointing channel 303 and causing accumulation;

[0042] A preferred embodiment, combined with Figure 9-11 As shown, the magnetic attraction component 302 includes a conveying part 6 and blades 7; a plurality of blades 7 are evenly arranged along the conveying part 6, and the cross section of the blades 7 is in the shape of a "water drop" and has magnetic force; the conveying part 6 drives the blades 7 to rotate in the water, and the magnetic force on the blades 7 is used to adsorb the ore raw materials. At the same time, the blades 7 are connected to the conveying part 6 by a rotating shaft, and rely on their own gravity to maintain a vertical state and contact with the raw ore. At the same time, there are gaps between adjacent blades 7 to facilitate the passage of water and avoid pushing the blades 7 to shake significantly. At the same time, the powder particles that pass through fall from the middle and contact the blades 7 at the bottom. Contact again, realize magnetic suction screening again, ensure the screening effect, and the blade 7 is in the shape of a water drop, and the bottom volume is large, which can further use gravity to maintain its own vertical state. At the same time, when the discharge part 304 discharges the raw materials on the blade 7, whether it is airflow or water flow, it can maintain its own stability very well. The airflow or water flow moves obliquely downward along both sides of the blade 7, generating a clamping force gathered toward the middle, ensuring that the blade 7 remains in a vertical state, and the force is inclined downward, which is convenient for flushing the ore raw materials adsorbed on the surface of the blade 7, thereby improving the unloading effect;

[0043] The transmission part 6 includes a transmission chain and a sprocket rotatably connected to the machine body, and both ends of the blade 7 are rotatably connected to the transmission chain, so that the blade 7 can maintain its vertical arrangement by its own gravity; a belt and a pulley can also be used to drive the blade 7;

[0044] In a preferred embodiment, magnetic suction plates 701 are provided on both sides of the blade 7, and the magnetic suction plates 701 are coated with a magnetic isolation layer 702, and the middle part is a hollow structure; the magnetic suction plates 701 on both sides of the blade 7 complete the adsorption and screening of the raw materials, and are coated with the magnetic isolation layer 702 to prevent mutual interference, and the hollow structure of the blade 7 further uses gravity to ensure that the blade 7 remains in a vertical downward state in the water, which is convenient for contact with the raw materials; wherein, the magnetic isolation layer 702 includes a rubber layer and a metal layer, the metal layer is preferably made of iron to ensure the demagnetization effect, and the rubber layer realizes a certain vibration elimination treatment to reduce the vibration force generated by the contact impact between the raw materials and the magnetic suction plate 701;

[0045] A preferred embodiment, in combination with Fig.15 As shown, magnetic suction plates 701 are provided on both sides of the blade 7, and the magnetic suction plates 701 are covered with magnetic isolation layers 702, and the bottom of the blade 7 has an inwardly concave arc area; when the discharge member 304 uses airflow to remove ore powder on the surface, the inwardly concave arc area at the bottom relatively increases the pressure intensity of the low-pressure area, weakens the influence of unstable vortex on the blade 7, thereby ensuring its own good stability and improving the discharge effect;

[0046] Among them, a semicircular counterweight block can be installed inside the blade 7 to maintain the stability of the blade 7 itself;

[0047] A preferred embodiment, in combination with Figure 4 and Figure 5 As shown, a vertical baffle 307 is provided below the discharge chute 305; the design of the vertical baffle 307 blocks the powder and granular raw materials passing through the gap between two adjacent blades 7, causing them to fall downward and contact the blades 7 below, completing adsorption and filtration again to ensure the recovery effect.

[0048] Combination Figure 6 , Figure 7 and Fig.12 As shown, the pushing device 4 includes a plurality of threaded rods 401 and a base 402; the base 402 is located below the secondary fine separation part 3 and is connected to the precipitation collection part 5; a semicircular channel 403 is provided on the base 402, and both sides of the semicircular channel 403 are inclined surfaces, and a sink 404 is provided at the end of the base 402; the threaded rod 401 is installed in the semicircular channel 403; the ordinary ore raw materials after magnetic filtration fall onto the base 402, and the inclined surface design on both sides of the semicircular channel 403 gathers the ore into the semicircular channel 403 to realize the collection of the ore, and when it needs to be discharged, the threaded rod 401 rotates and pushes it into the sink 404 along the semicircular channel 403, and then it is discharged by the precipitation collection part 5; wherein, the threaded rod 401 adopts a multi-group distribution to improve the working efficiency, and is driven to rotate by an electric motor;

[0049] A preferred embodiment, in combination with Figure 5As shown, the sedimentation collection part 5 includes a conveying hopper 501 and a sedimentation area 502; the bottom of the conveying hopper 501 is located in the sedimentation tank 404; the sedimentation area 502 includes a "V-shaped" side plate 503 and a plurality of stop plates 504 arranged in a staggered manner in the middle and inclined downward; the conveying hopper 501 is driven by a motor to extract and discharge the ore raw materials in the sedimentation tank 404, and the sedimentation area 502 cooperates with the position of the sedimentation tank 404 to form an area with relatively stable water flow, thereby reducing the lifting of powder and particle raw materials. At the same time, the V-shaped side plates 503 form a discharge channel for the conveying hopper 501, thereby reducing the disturbance of the surrounding water flow when the conveying hopper 501 moves, and the powder and particle ore can be precipitated and discharged again in the sedimentation area 502, and the stop plate 504 prevents the powder and particles from being lifted upward and discharged from the water outlet position, thereby affecting the subsequent recycling of wastewater.

[0050] Combination Figure 2 As shown, the surface of the cylinder 101 has a carbon fiber surface layer 102; the cylinder 101 is coated with the carbon fiber surface layer 102, which effectively improves the surface's high temperature resistance, friction resistance, heat conduction and corrosion resistance, and at the same time improves its own strength to ensure the stability of the structure;

[0051] The carbon fiber cylinder 101 can eliminate the eddy current electricity generated by the metal material and the magnetic field, avoid cutting the magnetic lines, and will not generate heat, thus ensuring the magnetism during operation. In addition, the carbon fiber cylinder 101 has good thermal conductivity, which can improve the heat dissipation effect, ensure the working temperature of the cylinder, and stabilize the magnetic separation effect. At the same time, the carbon fiber surface layer 102 reduces the friction generated during the contact with the material, which can further ensure its own working temperature.

[0052] Moreover, the corrosion resistance of carbon fiber itself ensures the sealing of the coil inside the cylinder 101, effectively preventing the corrosion and oxidation of the magnet caused by the entry of external air, which would result in a reduction in the magnetic field.

[0053] Combination Figure 1 As shown, both ends of the vibration plate 202 are driven by high-frequency vibrators, which drive the vibration plate 202 to perform preliminary screening on the raw materials.

[0054] Combination Figure 4 and Figure 5 As shown, a water inlet is provided on the left side of the machine body 1 above the power member 301 , and a water outlet is provided above the sedimentation area 502 , for replacing the water quality inside the machine body 1 .

[0055] Combination Figure 6 , Figure 7 and Fig.16As shown, a triangular horizontal baffle is provided at a height of 20-35 cm above the semicircular channel 403 and below the magnetic attraction component 302, and its width is equal to or slightly larger than the diameter of the threaded rod 401, which does not affect the falling of the ore raw materials, and at the same time reduces the disturbance of the precipitated powder ore during the flow of water, thereby improving the precipitation effect. A horizontal flat plate structure can also be used, but it is easy for raw materials to accumulate.

[0056] Combination Figure 1-16 As shown, the specific working process is as follows:

[0057] The ore that has been crushed, screened, and preliminarily cleaned evenly enters the body 1 from the top. During the rotation of the cylinder 101, the ilmenite is adsorbed by the weak magnetism of the ilmenite. As the cylinder 101 rotates, the ilmenite is driven to fall onto the inclined platform 201 to complete classification and recovery. Ordinary ore raw materials fall onto the vibration plate 202 under the action of inertia. The vibration plate 202 screens small pieces of raw materials and powdery raw materials, and they fall into the drainage channel 203 and evenly fall into the water through the drainage channel 203. The power part 301 generates water waves in stages to push the raw materials to contact with the blades 7, thereby realizing magnetic adsorption again. Moreover, the ore is cleaned under the impact of water flow, thereby improving the quality of the discharged material. The conveying part 6 drives the blade 7 to rotate in stages at the same time, thereby driving the blade 7 to move obliquely upward. The multiple groups of power parts 301 push the raw materials to contact the blade 7 for many times to ensure the cleaning effect. The ordinary ore raw materials fall into the semicircular channel 403 under the action of gravity to achieve aggregation. The threaded rod 401 rotates to push the ore into the sink 404 and is discharged from the conveying hopper 501, completing the overall operation and integrated processing. At the same time, repeated screening is avoided, the work efficiency is improved, and the floor space is reduced.

[0058] The water consumption inside the body 1 is 40%-55% of that of the traditional high-gradient magnetic separator, which greatly reduces the use of water resources. The used water can be filtered and recycled again, and the water containing mud will not affect the adsorption of ore, further reducing the water consumption and construction conditions. At the same time, the overall structural design is reasonable, and the secondary screening of the magnetic suction component 302 does not require electricity, which effectively reduces the consumption of electricity and reduces the overall production cost of the enterprise. Specific implementation method 2

[0060] Combination Fig.14As shown, the magnetic suction component 302 includes a conveying part 6 and blades 7; a plurality of blades 7 are evenly arranged along the conveying part 6, and the cross-section of the blades 7 is "triangular" and has magnetic force; magnetic suction plates 701 are provided on both sides of the blades 7, and the magnetic suction plates 701 are coated with a magnetic isolation layer 702; the blades 7 can also adopt a triangular cross-sectional structure, and the magnetic suction plates 701 on both sides serve as the main working area to adsorb ilmenite powder. The top of the triangular blade 701 is connected to the conveying part 6 to drive the blade 7 to rotate. At the same time, the blade 7 is kept in a vertical state during work by utilizing the characteristics of a larger volume below and a smaller volume above. The structure itself is convenient for the unloading part to unload the mineral powder magnetically adsorbed on the surface of the blade 7. At the same time, the triangular blade 7 is a planar structure as a whole, which is convenient for processing and manufacturing in the actual process.

[0061] In summary, the present invention adopts multiple groups of structures to cooperate with each other, realizes multiple screening of ore raw materials, ensures full utilization of raw materials, avoids ilmenite ore being discharged with waste materials, and causes waste. At the same time, liquid is used as a medium in the machine body during the secondary separation process, which improves the contact between the raw material and the blade 7, thereby ensuring the adsorption effect, and in the liquid, the powdered raw material is easy to disperse, thereby improving the magnetic attraction effect, and uses water waves or air to disturb the water flow to promote the powdered ore to contact and screen with the blade 7. At the same time, under the action of water flow resistance, the ore is prevented from directly impacting the blade 7 with a large force, thereby protecting the safety of the surface of the blade 7, and improving the service life. The traditional processing lines and procedures are changed, the production cost is reduced, and the use requirements of manufacturers of different sizes are met.

[0062] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention.
