[0001] The present application relates to the field of mineral powder recovery, and in particular to a tailings recovery machine. Background Art

[0002] Tailings recovery machine is a machine used in the industry for tailings production and recovery. Tailings recovery device can effectively reduce the loss of tailings, control it below 3% (calculated by volume), effectively reduce the content of effective components in tailings water, solve the pollution of tailings to the environment, and meet the emission standards required by environmental protection. It is widely used in metallurgy, mining, water conservancy, hydropower, sand and gravel plants, glass plants, coal preparation plants, coarse coal recovery and environmental protection projects, shield machines (mud purification) and other engineering projects.

[0003] When the tailings recovery machine recovers iron ore concentrate, it will scrape the iron ore concentrate from the disk for collection. Iron ore concentrate is the ore powder processed by crushing, grinding, beneficiation, etc. Iron ore concentrate will contain large pieces of granular ore. If iron ore concentrates of different specifications are processed, the large pieces of granular ore will directly affect the quality of the finished pellets. It is recommended to expand in the direction of facilitating the separation of iron ore concentrates of different particle sizes to reduce the adverse effects of large granular ore on the finished pellets. Utility Model Content

[0004] In order to reduce the occurrence of large particle impurities such as crushed ore mixed in the iron ore concentrate recovered by the tailings recovery machine, the present application provides a tailings recovery machine.

[0005] The tailings recovery machine provided in this application adopts the following technical solution:

[0006] A tailings recovery machine comprises a box body, the upper side of which is open and a magnetic disk is provided inside the box body, one side of the box body is provided with a plurality of scrapers, and each of the scrapers can abut against the magnetic disk and be used to scrape off the iron ore concentrate adhered to the magnetic disk, and one side of the box body is also provided with a grading screening component that can receive the iron ore concentrate scraped off by the scraper.

[0007] By adopting the above technical scheme, after the iron ore concentrate and crushed ore enter the interior of the box, the iron ore concentrate and crushed ore are adsorbed on the magnetic disk by rotating the magnetic disk, and then during the rotation of the magnetic disk, the iron ore concentrate and crushed ore on the magnetic disk are scraped by the scraper plate into the grading and screening component, and then the iron ore concentrate and crushed ore are screened by the grading and screening component, thereby reducing the trouble of the iron ore concentrate being mixed with crushed ore, which affects the subsequent treatment of the iron ore concentrate in the tailings.

[0008] Optionally, the graded screening assembly includes a screening box, which is fixedly connected to a material guide plate on one side of the screening box close to the box body, the material guide plate is connected to the plurality of scrapers and can receive the iron ore concentrate dropped by the scrapers into the interior of the screening box, and a primary filter and a secondary filter are provided inside the screening box, the primary filter and the secondary filter are spaced apart from top to bottom, and the filter holes of the primary filter are larger than the filter holes of the secondary filter.

[0009] By adopting the above technical solution, after the scraper scrapes off the iron ore concentrate and crushed ore on the magnetic disk, the iron ore concentrate and crushed ore fall onto the guide plate, and then enter the screening box along the guide plate. Thereafter, the iron ore concentrate and crushed ore pass through the primary filter and the secondary filter in turn under the action of gravity, and the crushed ore is retained on the upper side of the primary filter or the secondary filter, thereby realizing the screening process of the iron ore concentrate.

[0010] Optionally, the primary filter and the secondary filter are both arranged to be gradually inclined upward from a side close to the box body to a side away from the box body, and the upper sides of the primary filter and the secondary filter are slidably abutted with a push plate, one side of each push plate is connected to a cylinder for driving the push plate to move, and a discharge port is provided on a side of the screening box away from the box body and at a position above the primary filter and the secondary filter.

[0012] Optionally, each of the push plates is provided with a plurality of feeding holes which are larger than the filter holes on the primary filter screen.

[0013] By adopting the above technical solution, since the push plate is provided with a feeding hole and the primary filter screen and the secondary filter screen are both inclined, the phenomenon of the two push plates pushing the iron ore concentrate out of the discharge port is reduced.

[0014] Optionally, the outer side wall of the screening box is located at the lower side of each of the discharge ports and is fixedly connected to a material receiving platform.

[0015] By adopting the above technical solution, due to the existence of the collecting platform, the crushed ore pushed out from the discharge port can be temporarily stored on the collecting platform, which facilitates the process of sorting and processing the crushed ore by the staff.

[0016] Optionally, a vibrating assembly for vibrating the screening box is connected to one side of the screening box.

[0018] Optionally, the vibration assembly includes a vibration motor, and the output shaft of the vibration motor is fixedly sleeved with a vibration cam that can abut against the side wall of the screening box during rotation.

[0019] By adopting the above technical solution, when the screening box needs to be vibrated, the vibrating motor is started, and the vibrating motor drives the vibrating cam to rotate.

[0029] The following is combined with Figure 1 -Attached Figure 2 This application is described in further detail.

[0030] The present application embodiment discloses a tailings recovery machine, referring to Figure 1 , including a box body 1, the box body 1 is hollow inside and open on the upper side, and a feed pipe 11 is connected to one side of the box body 1. A vertically arranged magnetic disk 2 is arranged inside the box body 1, and the lower side of the magnetic disk 2 is arranged inside the box body 1. A rotating shaft 21 is penetrated and fixedly connected to the middle of the magnetic disk 2, and the end of the rotating shaft 21 penetrates the adjacent side wall of the box body 1 and is rotatably connected to the side wall of the box body 1. One end of the rotating shaft 21 that penetrates the side wall of the box body 1 is fixedly connected to a rotating motor 22, and the rotating motor 22 is installed on the outer wall of one side of the box body 1.

[0031] Scrapers 3 are provided on opposite sides of the box body 1 on the side of the disk 2 away from the feed pipe 11. The scrapers 3 are gradually inclined downward from the side close to the disk 2 to the side away from the disk 2. The opposite sides of the two scrapers 3 are in contact with the adjacent disks 2.

[0032] A grading and screening component 4 is connected to the side of the two scrapers 3 away from the magnetic disk 2. The grading and screening component 4 is used to receive the iron ore concentrate dropped by the scrapers 3 and screen the iron ore concentrate.

[0033] When the tailings enter the box body 1 from the feed pipe 11, the rotating motor 22 is started to drive the magnetic disk 2 to rotate, so that the magnetic disk 2 can rotate from top to bottom and pass through the middle position of the two scrapers 3, so that the iron ore concentrate adsorbed on the magnetic disk 2 can be dropped by the scraper 3, and then the scraped iron ore concentrate enters the grouping screening device for screening, so as to separate the iron ore concentrate and the crushed ore mixed in the iron ore concentrate.

[0034] The iron ore concentrate on the magnetic disk 2 is scraped off by the scraper 3 and screened by the grouping screening device, thereby reducing the iron ore concentrate in the tailings recovery from being mixed with crushed ore, thereby affecting the subsequent processing.

[0035] Reference Figure 1 and Figure 2 The grading screening assembly 4 includes a screening box 41 which is hollow inside and open at the top. A material guide plate 42 is fixedly connected to the upper end of the screening box 41 close to the box body 1. The material guide plate 42 is located at the lower side of the two scrapers 3 and is arranged parallel to the two scrapers 3. Each scraper 3 is detachably connected to the material guide plate 42 by bolts. The material guide plate 42 is located between the two scrapers 3 and is provided with a groove for the magnetic disk 2 to pass through.

[0036] A primary filter screen 43 and a secondary filter screen 44 are arranged in sequence from top to bottom inside the screening box 41. The primary filter screen 43 and the secondary filter screen 44 are arranged gradually upwardly tilted from the side close to the box body 1 to the side away from the box body 1, and the primary filter screen 43 and the secondary filter screen 44 are arranged parallel to each other. The filter holes provided on the primary filter screen 43 are smaller than the filter holes provided on the secondary filter screen 44.

[0037] Both the primary filter 43 and the secondary filter 44 are provided with a push plate 45, which is in sliding contact with the upper surface of the adjacent primary filter 43 or the secondary filter 44, and each push plate 45 is provided with a material passage hole 451 whose size is larger than the filter hole provided on the primary filter 43. Two cylinders 46 are fixedly connected to the side of the screening box 41 away from the box body 1, and the length direction of each cylinder 46 is arranged parallel to the inclination direction of the primary filter 43 and the secondary filter 44. The two cylinders 46 are arranged in a one-to-one correspondence with the two push plates 45, and the piston rod of each cylinder 46 slides through the screening box 41 and is fixedly connected to the corresponding push plate 45 inside the screening box 41.

[0038] A discharge port 411 is provided on one side of the screening box 41 away from the box body 1 and located above the primary filter screen 43 and the secondary filter screen 44, and the lower side wall of each discharge port 411 is flush with the upper side of the adjacent primary filter screen 43 or the secondary filter screen 44. A horizontally arranged material receiving platform 47 is fixedly connected to the outer wall of the screening box 41 located below the two discharge ports 411.

[0039] After the scraper 3 scrapes the iron ore concentrate and the crushed ore off the magnetic disk 2, the iron ore concentrate and the crushed ore slide along the inclined direction of the guide plate 42 to the inside of the screening box 41, and then the iron ore concentrate passes through the primary filter 43 and the secondary filter 44 in turn and falls to the bottom of the screening box 41, and the remaining crushed ore is retained on the upper side of the primary filter 43 or the secondary filter 44. Then, the two cylinders 46 are started, and each cylinder 46 drives the connected push plate 45 to move from the side away from the discharge port 411 to the side close to the discharge port 411, so that the crushed ore on the upper side of the primary filter 43 and the secondary filter 44 that is difficult to fall can be pushed out from the adjacent discharge port 411 and pushed onto the receiving platform 47, thereby realizing the cleaning process of the crushed ore on the upper side of the primary filter 43 and the secondary filter 44.

[0040] Reference Figure 1 A vibrating assembly 5 is also connected to one side of the screening box 41.

[0041] The vibrating assembly 5 can accelerate the time for the iron ore concentrate to fall off the primary filter 43 and the secondary filter 44 , and can also accelerate the time for the iron ore concentrate and crushed ore on the guide plate 42 to enter the screening box 41 .

[0042] The vibrating assembly 5 includes a vibrating motor 51 fixedly connected to the outer wall of the screening box 41 , a vibrating cam 52 is fixedly connected to the output shaft of the vibrating motor 51 , and the vibrating cam 52 can abut against the side wall of the screening box 41 during rotation.

[0043] While the rotating motor 22 drives the magnetic disk 2 to rotate, the vibrating motor 51 is started to drive the vibrating cam 52 to rotate. The vibrating cam 52 knocks on the side wall of the screening box 41 during the rotation, thereby realizing the vibration operation of the primary filter 43, the secondary filter 44 and the guide plate 42 inside the screening box 41.

[0044] The implementation principle of a tailings recovery machine in an embodiment of the present application is: when the tailings need to be recovered, the tailings are introduced into the interior of the box 1, and then the rotating motor 22 and the vibrating motor 51 are started. The rotating motor 22 drives the magnetic disk 2 to rotate, so that the magnetic disk 2 can bring out the iron ore concentrate and crushed ore from the bottom of the box 1 and fall onto the guide plate 42 under the action of the scraper 3.

[0045] Afterwards, the iron ore concentrate and crushed ore fall into the screening box 41 along the guide plate 42, and the iron ore concentrate falls to the bottom of the screening box 41 after passing through the primary filter 43 and the secondary filter 44. Then, the two cylinders 46 are started, and the two cylinders 46 drive the two connected pushing plates 45 to push the crushed ore on the primary filter 43 and the secondary filter 44 to the two receiving tables 47.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
