Description

Technical Field

[0001] The invention relates to the technical field of mineral processing, in particular to an iron ore separation and impurity removal device. Background Art

[0002] Iron ore separation and impurity removal device is a special equipment used to remove impurities and sort iron ore during iron ore processing. The purpose of this device is to improve the purity of iron ore and remove impurities in it, so as to improve the efficiency of subsequent processing and product quality.

[0003] During the operation of the iron ore sorting and impurity removal device, the iron ore is first introduced into the material conveying trough, and then the cylinder rotates. Due to the magnetic attraction provided by the magnet, the ferromagnetic impurities contained in the iron ore are adsorbed to the inner surface of the cylinder. As the cylinder continues to rotate, these non-ferromagnetic impurities flow to the discharge pipe with the water flow, and when the cylinder moves to the non-magnetic area with the ferromagnetic impurities, the water flow sprayed by the unloading water pipe washes the ferromagnetic impurities out of the cylinder and falls into the discharge box to complete the separation.

[0004] However, in the process of ferromagnetic impurities being adsorbed, the ferromagnetic impurities accumulate and press on the non-ferromagnetic impurities. This phenomenon causes the non-ferromagnetic impurities to be forced to migrate together with the ferromagnetic impurities, thereby reducing the accuracy and efficiency of iron ore sorting.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-8 The present invention provides a technical solution for an iron ore separation and impurity removal device: according to Figure 1-6As shown, an iron ore sorting and impurity removal device includes a frame 1, a cylinder 101, a magnet 102, a material conveying trough 104 and a first motor 107, wherein the first motor 107 is mounted on the surface of the frame 1, the cylinder 101 is rotatably mounted with the frame 1, the output shaft of the first motor 107 is fixedly connected with the cylinder 101, the material conveying trough 104 is fixedly connected with the frame 1, a discharge port 110 is provided on the surface of the material conveying trough 104, the magnet 102 is fixedly mounted with the surface of the frame 1 and is located inside the cylinder 101, the feed box 103 and the discharge box 108 are both fixedly connected with the frame 1 and are respectively connected with the feed port and the discharge port of the material conveying trough 104, the unloading water pipe 106 is installed inside the discharge box 108, the blowing water pipe 105 is installed inside the material conveying trough 104, and the discharge pipe 109 is connected with the material conveying trough 104.

[0024] The frame 1 is provided with a dispersion mechanism, which includes a second motor 201, a combing strip 205 and two guide rods 206. The frame 1 is fixedly provided with a first bracket 203, the second motor 201 is installed on the surface of the first bracket 203, the output shaft of the second motor 201 is fixedly connected with a first swing arm 202, one end of the first swing arm 202 is rotatably connected with a second swing arm 204, one end of the second swing arm 204 is rotatably connected with a rotating shaft 207, and the upper end of the combing strip 205 is fixedly connected with a slider 203. 08, the rotating shaft 207 is fixedly connected to the slider 208, the two guide rods 206 are fixedly connected to the frame 1, the slider 208 is slidably connected to the surfaces of the two guide rods 206, the combing bar 205 is in an arc shape that fits the surface of the cylinder 101, and the inner arc surface of the combing bar 205 is provided with a plurality of tooth grooves. The combing bar 205 with tooth grooves reciprocates on the surface of the cylinder 101 to move the iron ore layer on the cylinder 101, thereby turning over the iron ore layer, and will not cause ferromagnetic impurities to separate from the cylinder 101.

[0025] When used specifically, the finely crushed iron ore is introduced into the feed box 103 and then enters the material conveying trough 104. In this process, the water flow sprayed from the water pipe 105 is used to promote the smooth flow of the iron ore along the direction of the water flow. When the iron ore approaches the cylinder 101, the built-in magnet 102 begins to adsorb the ferromagnetic impurities in the iron ore, making it adhere to the surface of the cylinder 101, while the non-ferromagnetic impurities pass through the discharge port 110 with the water flow and are effectively separated through the discharge pipe 109. The ferromagnetic impurities move toward the discharge box 108 along with the cylinder 101 driven to rotate by the first motor 107. At the same time, the second motor 201 drives the first swing arm 202 and the second swing arm 204 to rotate. Through the cooperation of the second swing arm 204 and the guide rod 206, the reciprocating sliding action of the combing strip 205 on the surface of the cylinder 101 is realized, so as to move the iron ore layer on the cylinder 101 and flip its surface, effectively turning out the non-ferromagnetic impurities covered by the ferromagnetic impurities, thereby ensuring the high efficiency and accuracy of the magnetic separation process.

[0026] according to Figure 4 , Figure 5 and Figure 7 As shown, the material conveying trough 104 is provided with an anti-congestion mechanism, which includes a reflux conveying trough 303, a material baffle plate 306 and a rubber plate 312. A reflux hole is opened on the surface of the material conveying trough 104, and the reflux conveying trough 303 is fixedly connected to the surface of the material conveying trough 104 and is communicated with the reflux hole. A support plate 311 is fixedly installed inside the reflux conveying trough 303, and a third swing arm 307 is rotatably connected to the support plate 311. The material baffle plate 306 is fixedly connected to the third swing arm 307. The pressure increase inside the material conveying trough 104 will open the material baffle plate 306 to release excess iron ore into the reflux conveying trough 303, thereby reducing the single flow inside the material conveying trough 104.

[0027] Among them, a rubber plate 312 is fixedly connected to the inside of the reflux conveying trough 303, and the rubber plate 312 can control the pressure that the baffle plate 306 can withstand, and push the baffle plate 306 to close again when the pressure is reduced. Compared with elastic components such as springs, the rubber plate 312 can effectively avoid being stuck by iron ore and unable to rebound. One end of the rubber plate 312 is fixedly connected to a transfer frame 313, and the transfer frame 313 is rotatably connected to a support shaft 314. Side plates 308 are welded on both sides of the baffle plate 306, and the side sealing effect can be effectively improved by the side plates 308. A stopper 309 is fixedly connected to the inside of the material conveying trough 104, and the stopper 309 can prevent the baffle plate 306 from rotating toward the inside of the material conveying trough 104, resulting in failure to play a material blocking role.

[0028] The outer surface of the discharge box 108 is fixedly connected to the second bracket 301, and the surface of the second bracket 301 is fixedly installed with an air pump 302. The air delivery port of the air pump 302 is connected to the air injection pipe 305. The air is injected into the reflux conveying tank body 303 through the air pump 302, which can assist the iron ore conveying flow while preventing the iron ore from contacting the rotating part of the third swing arm 307 and affecting its rotation sensitivity. The air injection pipe 305 is connected to the reflux conveying tank body 303, and the interior of the reflux conveying tank body 303 is fixedly connected with a mesh plate 310. The mesh plate 310 can block the airflow, so that the airflow cannot be completely discharged at one time, and the airflow is dispersed more evenly when it is discharged through the mesh plate 310, thereby improving the use effect of the airflow. The discharge end of the reflux conveying trough 303 is connected to the guide conveying trough 304, and the guide conveying trough 304 is aligned with the connection between the feed box 103 and the material conveying trough 104. The guide conveying trough 304 can make the refluxed iron ore accurately enter the connection, and when the iron ore is blocked, the refluxed iron ore can play a dredging effect.

[0029] When used specifically, iron ore is introduced into the material conveying trough 104. If the conveying stability is poor, the single conveying volume may be abnormal, which may cause the material conveying trough 104 to be blocked or a large amount of iron ore may be dumped at one time. Such a phenomenon will weaken the sorting accuracy of the iron ore.

[0030] When excessive iron ore enters the material conveying trough 104, the pressure inside the material conveying trough 104 will rise sharply, forcing the baffle plate 306 to open to release the excess iron ore into the reflux conveying trough 303. The refluxed iron ore will be guided to the feed box 103 again. Such a cycle can ensure that the inflow of iron ore is more uniform and consistent, and can effectively reduce the risk of blockage of the material conveying trough 104 and the outflow of a large amount of iron ore at one time, thereby improving the accuracy and stability of iron ore sorting.

[0031] according to Figure 8 As shown, a magnetic testing mechanism is arranged on the material conveying trough body 104, and the magnetic testing mechanism includes a transverse conduit 401, a longitudinal conduit 403, an iron block 404 and two identification blocks 407. The longitudinal conduit 403 is fixedly inserted into the interior of the material conveying trough body 104, and the lower ends of the transverse conduit 401 and the longitudinal conduit 403 are fixedly connected and interconnected. Observation ports 402 are arranged at both ends of the transverse conduit 401, and the two identification blocks 407 are respectively located inside the two ends of the transverse conduit 401. The positions of the identification blocks 407 can be observed in time through the observation ports 402, and prompts of the identification blocks 407 can be obtained in time.

[0032] Among them, the iron block 404 is arranged inside the longitudinal duct 403, and two connecting ropes 406 are fixedly connected to the lower surface of the iron block 404, and two identification blocks 407 are fixedly connected to one end of the two connecting ropes 406 respectively. The surfaces of the two identification blocks 407 are painted with red paint, and the identification blocks 407 are coated with eye-catching red identification materials to facilitate operators to quickly detect abnormal conditions. The inside of the transverse duct 401 is rotatably connected with two steering shafts 408, and the steering shafts 408 can prevent the connecting rope 406 from getting stuck when it is bent. The inside of the longitudinal duct 403 is fixedly connected with a support block 405, and the support block 405 can prevent the iron block 404 from falling too high and being unable to be attracted again when the magnetic force is restored. The cross-sectional shape of the longitudinal duct 403 is a triangle. Since the longitudinal duct 403 penetrates the material conveying trough 104, the triangular longitudinal duct 403 can play a role in guiding flow and reducing flow resistance.

[0033] When in use, the magnetic force generated by the magnet 102 can pull the iron block 404 to move upward along the path, causing the identification block 407 to be located inside the transverse guide tube 401, so that it is out of the visible range. Once the magnet 102 fails and cannot maintain sufficient magnetic attraction, the iron block 404 will lose traction, and the identification block 407 with a ball on the lower surface will also slide down along the inclined transverse guide tube 401 due to the loss of traction until it reaches the observation port 402. The identification block 407 is coated with a striking red identification material, so that the operator can quickly detect the abnormal state and identify that the magnet 102 has lost sufficient magnetic attraction, and then immediately take maintenance measures, effectively preventing the failure of the iron ore sorting process due to the failure of the magnet 102 to be discovered in time.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
