Description

Technical Field

[0001] The utility model relates to the technical field of iron ore cleaning, in particular to an iron ore cleaning device. Background Art

[0002] Iron ore cleaning is a crucial step in iron ore processing. Iron ore typically contains various impurities, such as dirt, sand, and other non-magnetic minerals. These impurities not only reduce the grade (i.e., iron content) of the ore but also affect the efficiency and quality of subsequent processing. Cleaning effectively separates higher-purity iron minerals, thereby improving the quality and market value of the final product. Furthermore, cleaned iron ore is more readily suitable for subsequent processing steps, such as crushing, grinding, and magnetic separation.

[0003] Currently, iron ore is often cleaned using a drum washer, which primarily consists of a drum body, a transmission device, a water spray system, and a supporting structure. During operation, ore enters the drum from one end. As the drum slowly rotates, the spiral lining inside the drum drives the ore to tumble and move to the other end. During this process, a high-pressure water spray system sprays water onto the ore in the drum, washing away dirt and other impurities on the ore's surface. The cleaned ore is discharged from the other end of the drum, while the slurry, carrying dirt and other impurities, is discharged from the densely perforated drain section of the drum for wastewater treatment.

[0004] During the above-mentioned iron ore cleaning process, the muddy water discharged as wastewater still contains a large amount of fine iron ore particles. If they are effectively collected and recycled, the utilization efficiency of the iron ore can be further improved and resources can be saved.

[0005] To this end, the present application proposes an iron ore cleaning device to solve the above technical problems. Utility Model Content

[0006] The main purpose of the utility model is to solve the above-mentioned deficiencies and provide an iron ore cleaning device which can collect and recycle the fine iron ore particles in the discharged muddy water while cleaning the iron ore, thereby further improving the utilization efficiency of the iron ore.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0008] An iron ore cleaning device comprises: a drum ore washer body; a collecting cover fixedly arranged below the drainage section of the drum ore washer body; a diversion trough obliquely arranged below the collecting cover; a magnet fixedly arranged at the bottom of the diversion trough, used to attract fine iron ore in the mud flowing through the diversion trough and deposit it at the bottom of the diversion trough; a scraper slidingly arranged in the diversion trough along the diversion direction of the diversion trough; and a drive assembly fixedly arranged on the outer side wall of the diversion trough, used to drive the scraper to reciprocate along the diversion direction of the diversion trough.

[0009] Furthermore, the scraper includes side plates, a bottom plate and a back plate, the side plates and the bottom plate are respectively tightly attached to the inner side wall and the bottom of the guide groove, and the opening of the scraper is inclined upward toward one end of the guide groove.

[0010] Furthermore, long strip limiting grooves parallel to the bottom of the groove are opened on both sides of the guide groove, and a positioning rod passing through the limiting groove is fixedly provided on the outer wall of the side plate, and the driving assembly includes a twisted rod rotatably set on the outer wall of one side of the guide groove and parallel to the limiting groove, a crescent clamping block clamped in the twisted rod guide groove, a motor fixed on the guide groove and transmission connected to the twisted rod, and a connecting block with one end rotationally connected to the positioning rod and the other end rotationally connected to the crescent clamping block.

[0011] Furthermore, a guide rod parallel to the twisted rod is fixedly provided on the outer side wall of the guide groove, and the guide rod passes through the connecting block.

[0012] Furthermore, a gear is fixedly provided at one end of the positioning rod extending out of the side wall of the guide groove, and a rack that cooperates with the gear is fixedly provided on the outer side wall of the guide groove, and the rack is located below the end of the limiting groove that is inclined upward.

[0025] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] like Figure 1-6 As shown, the utility model provides an iron ore cleaning device, comprising:

[0027] Drum ore washing machine main body 1;

[0028] The collecting cover 2 is fixedly arranged below the draining section 3 of the drum ore washing machine body 1;

[0029] The guide groove 4 is obliquely arranged below the collecting cover 2;

[0030] The magnet 5 is fixedly arranged at the bottom of the guide trough 4 and is used to attract the fine iron ore in the mud flowing through the guide trough 4 and deposit it at the bottom of the guide trough 4;

[0031] The scraper 6 is slidably arranged in the guide groove 4 along the guide direction of the guide groove 4;

[0032] The driving assembly 7 is fixedly arranged on the outer side wall of the guide groove 4 and is used to drive the scraper 6 to reciprocate along the guide direction of the guide groove 4.

[0033] During use, the muddy water flowing out from the drainage section 3 of the drum ore washer body 1 converges through the collecting cover 2 and falls onto the guide trough 4. The magnet 5 absorbs the fine iron ore therein and deposits it on the bottom of the guide trough 4. Since the guide trough 4 is placed at an angle, the remaining muddy water flows out along the guide trough 4 under the action of its own gravity. The driving component 7 drives the scraper 6 to perform a circular reciprocating motion in the guide trough 4, and the fine iron ore particles deposited on the bottom of the trough are discharged from the upward end of the guide trough 4 and collected in a container, thereby separating the fine iron ore particles in the muddy water and improving the utilization rate of the iron ore.

[0034] In one embodiment, the scraper 6 includes a side plate 61 , a bottom plate 62 and a back plate 63 . The side plate 61 and the bottom plate 62 are respectively attached to the inner wall and the bottom of the guide groove 4 . The opening of the scraper 6 faces one end inclined upward toward the guide groove 4 .

[0035] This design makes it difficult for iron ore particles to pass through the gap between the scraper 6 and the guide groove 4, thereby ensuring the scraping effect of the scraper 6.

[0036] In one embodiment, long strip limiting grooves 8 parallel to the bottom of the groove are opened on both sides of the guide groove 4, and a positioning rod 9 passing through the limiting groove 8 is fixedly set on the outer wall of the side plate 61. The driving assembly 7 includes a twisted rod 71 rotatably set on the outer wall of one side of the guide groove 4 and parallel to the limiting groove 8, a crescent clamping block 72 clamped in the guide groove of the twisted rod 71, a motor 73 fixedly set on the guide groove 4 and transmission connected to the twisted rod 71, and a connecting block 74 with one end rotatably connected to the positioning rod 9 and the other end rotatably connected to the crescent clamping block 72.

[0037] With this design, after starting the motor 73, the motor 73 drives the twisted rod 71 to rotate, and the twisted rod 71 drives the crescent block 72 and the connecting block 74 to perform a circular reciprocating motion along the axial direction of the twisted rod 71, and then the connecting block 74 drives the positioning rod 9 and the scraper 6 to perform a circular reciprocating motion along the limiting groove 8, so that the scraper 6 can continuously scrape the fine iron ore at the bottom of the guide groove 4 away from the guide groove 4.

[0038] In one embodiment, a guide rod 10 parallel to the twisted rod 71 is fixedly provided on the outer wall of the guide groove 4 , and the guide rod 10 passes through the connecting block 74 .

[0039] With this design, the guide rod 10 is used to guide the reciprocating motion of the connecting block 74, thereby further improving the stability and smoothness of its motion.

[0040] In one embodiment, a gear 11 is fixedly provided at one end of the positioning rod 9 extending out of the side wall of the guide groove 4, and a rack 12 cooperating with the gear 11 is fixedly provided on the outer wall of the guide groove 4. The rack 12 is located below the end of the limiting groove 8 that is inclined upward.

[0041] With this design, when the scraper 6 moves to the rack 12, the rack 12 drives the gear 11 to rotate, and the gear 11 drives the scraper 6 to flip downward through the positioning rod 9, dumping out the fine iron ore accumulated in the scraper 6.

[0042] In one embodiment, a notch 13 is provided at the bottom of the guide groove 4 and at a position corresponding to the rack 12 .

[0043] This design ensures that the scraper 6 will not interfere with the bottom of the guide trough 4 when it is turned over and dumping the fine iron ore.

[0044] In one embodiment, the collecting cover 2 includes an arc portion 21 and a trapezoidal portion 22 , and the arc portion 21 and the trapezoidal portion 22 are tangent to each other at a joint.

[0045] With this design, the arc portion 21 can better fit with the drainage section 3, which is conducive to more sufficient collection of muddy water drained from the drainage section 3, and the trapezoidal portion 22 further gathers the muddy water collected by the arc portion 21. The tangency of the two can reduce the resistance encountered by the muddy water when flowing along the wall inside the collecting cover 2.

[0046] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.

[0047] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0048] In addition, "multiple" means more than two. Furthermore, the technical solutions of the various embodiments may be combined with each other, but this must be based on the premise that they can be implemented by a person of ordinary skill in the art. If the combination of technical solutions is mutually inconsistent or cannot be implemented, it shall be deemed that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
