[0029] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0030] See also Figure 1-3 In this embodiment, a high-frequency fine particle sorting device for iron ore concentrate includes a sorting box 1, a filtering mechanism and a sorting mechanism. The filtering mechanism is installed in the upper inner part of the sorting box 1, and the sorting mechanism is installed in the lower inner part of the sorting box 1. Guide plates are fixed on the left and right side walls of the sorting box 1. The guide plates are used to guide the screened iron ore concentrate out of the sorting box 1.

[0031] The filtering mechanism includes a filter box 3, a mounting block 21, a threaded column 19, a fixed frame 16, a first spring 17, a filter box 3 and a movable rod 18. The mounting block 21 is fixedly connected to the left and right sides of the filter box 3, the threaded column 19 is fixedly installed at the bottom of the mounting block 21, the first spring 17 is installed inside the fixed frame 16, the fixed frame 16 is fixedly installed on the left and right inner walls of the sorting box 1, the movable rod 18 is fixedly connected to one side of the first spring 17, and the end of the movable rod 18 away from the first spring 17 passes through the fixed frame 16 and extends to the outside. The threaded column 19 is inserted into the inside of the movable rod 18, the filter screen 10 is embedded and fixed at the bottom of the filter box 3, and a driving component for pushing the filter box 3 to shake is installed on the left side of the filter box 3.

[0032] The driving assembly includes a cam 4 and a driving motor. The driving motor is fixedly mounted on the back of the sorting box 1. A rotating rod is fixedly connected to the output shaft of the driving motor. The end of the rotating rod away from the driving motor passes through the sorting box 1 and extends to the inside and is fixedly connected to the cam 4.

[0033] See also Figure 1 In this embodiment, a discharge port 6 is provided on the right side of the sorting box 1, and a chute is provided on the right side of the sorting box 1. A slider is slidably connected to the inside of the chute, and a baffle 5 is fixedly installed on the right side of the slider. A magnet is fixed on the inner top wall of the chute, and an iron block is embedded and fixed on the top of the slider. By setting the baffle 5 to block the right side of the discharge port 6, the discharge port 6 is blocked. The baffle 5 can be pulled upward to expose the discharge port 6, and the iron block can be fixed to the magnet to prevent it from sliding down.

[0034] It is understandable that by providing a driving assembly and driving the cam 4 to rotate via the driving motor, the cam 4 will come into conflict with the filter box 3 when rotating, thereby pushing the filter box 3 to shake left and right.

[0035] The sorting mechanism includes a screening mesh plate 11, a fixed rod 22, a fixed block 23 and a second spring 24. The screening mesh plate 11 is slidably connected to the inside of the sorting box 1. The fixed rod 22 is fixedly connected to the left and right sides of the bottom of the screening mesh plate 11. The fixed rod 22 is a "T"-shaped rod. The fixed block 23 is fixedly installed on the left and right inner walls of the sorting box 1. The fixed rod 22 is slidably connected to the inside of the fixed block 23. The second spring 24 is sleeved on the outside of the fixed rod 22 and fixed between the fixed block 23 and the fixed rod 22.

[0036] Among them, by setting up a sorting mechanism, it is convenient to finely separate the iron ore concentrate after filtering out impurities, so that the coarse iron ore concentrate and the fine iron ore concentrate can be sorted and collected.

[0037] See also Figure 1 and Figure 4 In this embodiment, a feed hopper 2 is fixed through the top of the sorting box 1, a discharge port 12 is opened at the bottom of the sorting box 1, support legs 15 are fixed on the left and right sides of the bottom of the sorting box 1, and a horizontal plate 13 is fixedly installed between the left and right support legs 15. A material receiving box 14 is placed on the top of the horizontal plate 13, and the material receiving box 14 is located below the discharge port 12. A box door 25 is hinged on the front surface of the sorting box 1.

[0038] It should be noted that by opening the box door 25 and rotating and removing the fastening nut 20, the filter box 3 can be moved upward to remove the threaded column 19 from the movable rod 18, and the filter box 3 can be taken out of the sorting box 1 to facilitate pouring out the filtered impurities.

[0039] It is understandable that by arranging the collecting box 14 and placing it on the top of the horizontal plate 13, it is convenient to collect the iron ore fines discharged after sorting, and the collecting box 9 can be removed from the limiting rod 8 by moving the collecting box 9 upward.

[0040] See also Figure 2 In this embodiment, the external thread of the threaded column 19 is connected with a fastening nut 20, and the fastening nut 20 is pressed against the bottom of the movable rod 18. The cross section of the movable rod 18 is a rectangular structure.

[0041] The filter box 3 is fixed to the movable rods 18 on both sides by providing threaded columns 19 and fastening nuts 20 .

[0042] See also Figure 1 and Figure 5 In this embodiment, two limiting rods 8 are fixedly connected to the right side of the sorting box 1, and a collecting box 9 is movably connected between the two limiting rods 8. The front and rear sides of the collecting box 9 are fixedly connected with L-shaped rods 7, and the L-shaped rods 7 are inserted into the inside of the limiting rods 8.

[0043] The L-shaped rod 7 is inserted into the interior of the limiting rod 8 to support the collecting box 9, so that the collecting box 9 is hung at the lower right of the discharge port 6, which is convenient for collecting the discharged iron ore fines.

[0044] The working principle of the above embodiment is as follows: when in use, the iron ore powder is poured into the feed hopper 2 and falls into the interior of the filter box 3. The cam 4 is driven by the driving motor to rotate to push the filter box 3 to move left and right, and the elasticity of the first spring 17 itself can make the filter box 3 shake left and right to filter out the impurities therein, thereby avoiding the impurities filtered out of the filter box 3 from clogging the filter screen 10, which can speed up the filtration speed. The filtered iron ore powder falls on the screening mesh plate 11, and under the action of gravity, the screening mesh plate 11 will move down, causing the second spring 24 to expand and contract. Under the elastic action of the second spring 24, the screening mesh plate 11 can be shaken up and down to sort out iron ore powder of different specifications. The finer iron ore powder will fall into the receiving box 14 for collection, and the coarser iron ore powder will be discharged into the collecting box 9 through the discharge port 6 for collection, thereby improving the efficiency of iron ore screening.
