Description

Technical Field

[0001] The invention relates to the technical field of electromagnetic material separation, in particular to ilmenite separation equipment. Background Art

[0002] Ilmenite is an oxide mineral of iron and titanium, also known as titanomagnetite, and is the main ore for refining titanium. Ilmenite is heavy, gray to black, with a little metallic luster, and the crystals are generally plate-shaped, and the crystals are aggregated together in blocks or granules.

[0003] In the prior art, for example, Chinese patent publication number: CN207238241U discloses an ilmenite sorting device, including a sorting box, a feed pipe is provided at the upper end of the sorting box, two tangent rolling rollers are provided in the feed pipe, two motors corresponding to the positions of the rolling rollers are provided on the outer wall of the feed pipe, the output shaft end of the motor passes through the feed pipe and is fixedly connected to one end of the rolling roller, a plurality of rotating shafts are provided at equal intervals in the horizontal direction inside the sorting box, a rotating drum is fixedly sleeved on the rotating shaft, an electromagnet is provided on the surface of the rotating drum, one end of the rotating shaft is rotatably connected to the inner wall of the sorting box, the other end of the rotating shaft passes through the side wall of the sorting box, the rotating shaft is located on the side wall outside the sorting box and is fixedly sleeved with a first transmission wheel, and a first transmission belt is sleeved between the plurality of transmission wheels.

[0004] However, the above patents have the following deficiencies:

[0005] By utilizing the physical property that titanium cannot be adsorbed by magnets, the mixed powder particles formed after the ore is crushed and ball-milled can be subjected to the electromagnetic sorting step. The equipment involved in the above patent can realize the processes of crushing, feeding and magnetic separation in an integrated manner by improving the traditional structural layout and adding multiple collaborative components, reducing manual auxiliary items and reducing the harm to workers caused by toxic substances. However, there are still some shortcomings, such as: the titanium content in the ore is more than 50%, so it is generally higher than the iron content. The equipment places electromagnets at equal distances on the rollers. When the material powder falls freely, the iron-containing powder is adsorbed and the titanium-containing powder is continuously discharged to achieve the purpose of sorting. However, as the sorting time increases, the iron powder adsorbed on the magnet is too large, resulting in an increase in the diameter of the cylinder, which gradually reduces the falling gap, which not only causes the titanium-containing powder to fall slowly, but also causes part of the titanium-containing powder to be mixed into the iron-containing powder adsorption structure.

[0006] Therefore, we proposed an ilmenite sorting equipment to solve the above problems. Summary of the invention

[0007] The object of the present invention is to provide an ilmenite sorting device, which adopts a combined treatment method of air separation and magnetic separation through a secondary air separation mechanism and an electromagnetic separation mechanism connected to a secondary process box, and unifies the size of titanium-containing and iron-containing particles entering the machine body, which is convenient for adjusting the wind force intensity of the lower stage. Most of the titanium-containing particles can be separated during the air separation process, reducing the burden of the lower magnetic separation.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention sets a screening mechanism, a secondary air separation mechanism and an electromagnetic separation mechanism. The mixed powder particles are poured into the primary process box from the top and continuously cross the inside of the first metal screen. The purpose is to ensure that the size of the powder particles entering the machine body is basically the same. The screened powder particles can only fall from the drainage cover under the restriction of the first gathering funnel. At this time, each expansion cover will form a complete wind curtain inside the drainage cover to blow the materials falling vertically. Since the relative densities of titanium and iron are 4.5 and 7.8 respectively, and the mass of titanium is much smaller than that of iron, the air flow intensity is reasonably controlled. In the process, most of the titanium-containing particles are separated horizontally and continuously discharged from the equipment, while iron-containing and a small amount of titanium-containing particles are separated by gravity. Under the influence, they fall freely onto the electromagnetic panel, and the magnetic force generated on its surface will lock the iron-containing particles, while a small amount of titanium-containing particles will be discharged from the corresponding feeding holes under mechanical vibration. The mechanism adopts a combined treatment method of air separation and magnetic separation to unify the size of the titanium-containing and iron-containing particles entering the machine body, which is convenient for adjusting the wind strength of the lower stage. Most of the titanium-containing particles can be separated during the air separation process, reducing the burden of the lower magnetic separation. Subsequently, under mechanical vibration, a small amount of titanium-containing particles doped in the iron-containing particles can be completely separated out, and the method of gradually reducing the total amount of particles can, on the one hand, avoid channel blockage and ensure the work efficiency and continuous work ability of the equipment; on the other hand, it can ensure the integrity of material sorting and improve the work quality of the equipment.

[0024] 2. The present invention sets up a screening mechanism and an electromagnetic sorting mechanism. A group of holes of the same size are opened inside the first metal screen, the electromagnetic panel and the second metal screen of the mechanism, and are equipped with a mechanical vibration component. This structural mode enables the powder particles entering the body to be effectively discharged, avoiding excessive retention inside the body due to different particle diameters, which increases the difficulty of subsequent cleaning.

The large volume of material after screening rolls on the inclined plane and enters the first discharge joint 311. As the retention amount increases, the stop valve 312 can be opened to discharge out of the equipment.

[0041] according to Figure 3 and Figure 7 As shown, a flange base 408 is fixedly installed on the rear surface of the secondary process box 2, a mounting sleeve 409 is fixedly installed on the inner wall of the flange base 408, and the exhaust end of the mounting sleeve 409 is connected to the interior of the secondary process box 2, an inner ring 410 is fixedly installed on the inner wall of the mounting sleeve 409, a group of hollow blocks 411 are fixedly inserted into the inner wall of the inner ring 410, a hollow sleeve 412 is fixedly sleeved between the outer walls of a group of hollow blocks 411, and a servo motor 413 is fixedly inserted into the inner wall of the hollow sleeve 412.

[0044] according to Figure 5 As shown, an independent power supply 508 is fixedly connected to the top of the electromagnetic panel 503, and the output end of the independent power supply 508 is connected to the internal wiring of the electromagnetic panel 503. The input end of the independent power supply 508 is fixedly connected to a group of third wires 509, and the input ends of a group of third wires 509 are all connected to the internal wiring of the equipment. By presetting the above components, the independent power supply 508 can provide a stable energy supply for the electromagnetic panel 503, avoiding magnetic disconnection during operation of the equipment and affecting the sorting quality.

[0045] according to Figure 8 As shown, a second horizontal support plate 513 is fixedly installed between the outer walls of the two second drive motors 512, a second wiring base 514 is fixedly installed on the bottom of the second horizontal support plate 513, a group of fourth wires 515 are fixedly connected inside the second wiring base 514, the input ends of a group of fourth wires 515 are connected to the internal wiring of the device, a group of fifth wires 516 are fixedly connected to the output end of the second wiring base 514, and the output end of each fifth wire 516 is respectively connected to the wiring terminal of a corresponding second drive motor 512.

[0046] according to Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the inner wall of the secondary process box 2 is fixedly installed with a third positioning frame 6, the inner wall of the third positioning frame 6 is fixedly installed with a second aggregation funnel 7, the bottom of the second aggregation funnel 7 is fixedly connected with an extension joint 8, and one side of the outer wall of the primary process box 1 is provided with a door frame 9, the outer wall of the door frame 9 is fixedly installed with a group of hinges 10, the outer wall of the door frame 9 is movably provided with a movable door 11, and the movable door 11 is connected to the door frame 9 through a group of hinges 10, and the outer wall of the movable door 11 is welded with a handrail 12.

[0047] according to Figure 1 , Figure 3 and Figure 4As shown, the inclined frame 301 is fixedly installed on the inner wall of the primary process box 1, the first positioning frame 401 and the second positioning frame 501 are both fixedly installed on the inner wall of the primary process box 1, and four groups of lifting frames 13 are welded on the outer wall of the secondary process box 2, and a load-bearing bracket 14 is fixedly installed between the bottom of each lifting frame 13.

[0048] The effect achieved by the entire mechanism is as follows: during the equipment preparation stage, the equipment is first moved to the designated working area, the handrail 12 is pulled, the movable door 11 is opened using the physical properties of the hinge 10, the internal state of the machine body is detected to ensure that the electromagnetic panel 503 and each of its discharge holes 506 do not contain retained particles, and then the movable door 11 is closed, and the external line is connected to the equipment power supply, in order to provide energy for the multiple electrical components contained therein.

[0049] In the primary screening stage, the first driving motor 306 is turned on. At this time, the first vibration seat 305 is in a working state, so that the first metal screen 303 body begins to vibrate irregularly, and the sorted mixed particles are introduced from the top of the primary process box 1 and continue to pass through the holes set in the first metal screen 303. The vibration effect can increase the falling rate of the particles retained on the first metal screen 303. However, the larger particles slowly move to the first feeding joint 311 with the vibration of the surface of the first metal screen 303 and are retained therein. This process can ensure that the particle size of the material entering the body is basically consistent.

[0050] In the particle air selection stage, the servo motor 413 is turned on and acts on the transmission rod 414, driving a group of fan blades 416 on the assembly joint 415 to rotate at high speed inside the installation sleeve 409, continuously extracting external air, and accelerating it to blow it into the wind collection cover 407, gradually converging it into the intersection box 406. As the internal air pressure increases, part of the high-speed airflow is evenly distributed to each equal distribution joint 417, and then discharged from the diversion pipe 418 in turn. During the process, the expansion cover 419 can increase the airflow diffusion area. Because multiple expansion covers 419 are equidistantly located in the drainage, In the hood 404, a complete transverse wind curtain can be formed inside the drainage hood 404, and the material particles passing through the first metal screen 303 are gathered in the first gathering funnel 402. The material particles are restricted by the channel, so that they are forced to fall from the inside of the drainage hood 404. When they come into contact with the wind curtain, the titanium-containing particles with smaller mass are blown out and continue to enter the interior of the collecting hood 420. After the transverse airflow is blocked by the inner wall of the collecting hood 420, the airflow strength is further weakened, and the titanium-containing particles are slowly discharged from the equipment from the second unloading joint 421.

[0051] During the electromagnetic sorting stage, the heavier iron-containing particles and a smaller amount of titanium-containing particles fall freely onto the electromagnetic panel 503 under the action of gravity. Prior to this, the independent power supply 508 is powered on, continuously inputting energy into the electromagnetic panel 503 to generate magnetism on its surface. After contacting the iron-containing particles, the latter can be tightly adsorbed. Since the magnetic isolation sleeve 507 can isolate the magnetism of the inner wall of each feeding hole 506, the iron-containing particles can be prevented from adhering to the feeding hole 506 to cause blockage. At the same time, the second driving motor 512 is turned on, so that the second vibration seat 511 is in a state of being made. In the working state, the vibration effect directly acts on the electromagnetic panel 503 and the second metal screen 505. At this time, the small amount of titanium-containing particles retained on the electromagnetic panel 503 cannot be adsorbed by the magnetic material, and will shake up and down under the influence of the vibration, and continue to jump into the nearest magnetic isolation sleeve 507 and fall downward. Since the built-in holes of the second metal screen 505 and the first metal screen 303 are of equal specifications, the titanium-containing particles that fall on the second metal screen 505 can easily pass through and gather in the middle of the second aggregation funnel 7, and finally be discharged from the inside of the extension joint 8.

[0052] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
