TECHNICAL FIELD

[0001] The application relates to the technical field of iron powder screening, in particular to a magnetic separator for efficiently separating iron powder. BACKGROUND

[0002] The mineral powder is a kind of fine powder particle, which is processed from ore or ore. After the ore is ground into powder, the mineral powder contains iron powder. In order to avoid affecting the subsequent production of the mineral powder, a magnetic separator is usually used to screen the iron powder from the mineral powder.

[0003] The electromagnetic magnetic separator disclosed in Chinese Patent (Publication No. CN203725255U) uses an electromagnet to adsorb iron powder, so it can adsorb and release iron powder as needed. It is suitable for application as a magnetic separator for separating iron powder and iron, but the screened mineral powder and iron powder cannot be further screened in the above-mentioned document. Since the screened mineral powder and iron powder still contain impurities such as sand, the purity of the screened iron powder or mineral powder is poor. CONTENT OF THE UTILITY MODEL

[0011] The technical scheme is adopted, the stop block can be fixed on the outer surface of the rotating rod, and the stop block can be stably rotated in the rotating hole of the recycling bin by cooperating with the top block in the same group, so that the phenomenon that the rotating rod moves forward and backward in the rotating hole of the recycling bin during rotation can be reduced.

[0012] Further, the two top blocks are located directly below the filter screen, and the two top blocks are respectively abutted with the front and rear walls of the lower end of the filter screen.

[0013] The technical scheme is adopted, the two top blocks are abutted with the bottom of the filter screen, so that when the two top blocks rotate, the sharp end of the top block can push the filter screen to move upward, and when the bottom end of the top block is in contact with the filter screen, the filter screen slides downward under the action of inertia, so that the filter screen can be shaken up and down in the recycling bin, so that the filtering effect on the iron powder can be accelerated.

[0014] Further, the rotating structure comprises two gears fixed on the outer surfaces of the two rotating rods, and the rotating structure further comprises two support plates fixed on the front and rear walls of the recycling bin, the right side walls of the two support plates are respectively fixed with electric push rods, and the output ends of the two electric push rods are respectively fixed with toothed plates.

[0016] Further, the two toothed plates are located directly above the two gears, and the lower side walls of the toothed plates are engaged with the top ends of the gears.

[0017] The technical scheme is adopted, so that when the two toothed plates move linearly at the top ends of the two gears, the toothed plates can be engaged with the top ends of the gears, that is, the toothed plates can drive the gears to rotate, and the gears can drive the rotating rod to rotate.

[0032] In addition, the front and rear recovery bins 3 are respectively arranged at the two discharge ports of the magnetic separator 2, so that the screened ore powder and iron powder can be taken.

[0033] Please refer to Figures 1 to 4 The screening structure in the embodiment comprises a filter screen 31, two top blocks 32, a rotating rod 33 fixedly installed in the two top blocks 32, a blocking block 34 fixedly installed on the outer surface of the two rotating rods 33, a rotating structure fixedly installed on the outer surface of the two rotating rods 33 for driving the rotating rods 33 to rotate, and a connecting structure fixedly installed on the left and right ends of the filter screen 31.

[0034] Among them, the front and rear walls of the recovery bin 3 are provided with rotating holes for the rotating rods 33 to penetrate and rotate in the rotating holes, so that the rotating rods 33 can extend into the inside of the recovery bin 3 through the rotating holes, so that the rotating rods 33 can be connected with the top blocks 32, and the opposite wall of the front and rear top blocks 32 is provided with a through hole for the rotating rods 33 to penetrate and be fixed in the through hole, so that the top blocks 32 can be fixed to the outer surface of the rotating rods 33 through the through hole, so that the rotating rods 33 can drive the top blocks 32 to rotate in the recovery bin 3, and the two top blocks 32 can push the filter screen 31 to move upward.

[0035] In addition, the opposite wall of the front and rear blocking blocks 34 is provided with a connecting hole for the rotating rods 33 to penetrate and be fixed in the connecting hole, the opposite wall of the front and rear top blocks 32 respectively abuts against the front and rear walls of the inner cavity of the recovery bin 3, and the opposite wall of the front and rear blocking blocks 34 respectively abuts against the front and rear walls of the recovery bin 3, so that the blocking blocks 34 can be fixed to the outer surface of the rotating rods 33, and the blocking blocks 34 can make the rotating rods 33 stably rotate in the rotating holes of the recovery bin 3 by cooperating with the top blocks 32 in the same group, so as to reduce the phenomenon that the rotating rods 33 move forward and backward in the rotating holes of the recovery bin 3 during rotation.

[0036] And, two top blocks 32 are located directly below the filter screen 31, and the two top blocks 32 are in abutment with the front and rear walls of the lower end of the filter screen 31, and the top block 32 is in a conical shape.

[0038] Secondly, the two toothed plates 38 are located directly above the two gears 35, and the lower side wall of the toothed plate 38 is in meshing engagement with the top end of the gear 35.

[0039] Please refer to Figure 2 and Figure 4 The connecting structure in the embodiment includes two T-shaped rods 39 fixed to the left and right walls of the inner cavity of the recycling bin 3. The interiors of the left and right groups of T-shaped rods 39 are each threadedly connected with a screw rod 310, and the top ends of the screw rods 310 are each fixed with an operating block 311.

[0040] At the same time, the left and right ends of the top end of the filter screen 31 are each provided with a circular hole for the T-shaped rod 39 to penetrate and slide therein, so that the filter screen 31 can slide on the surfaces of the left and right groups of T-shaped rods 39 through the circular holes, which can effectively limit the position height of the filter screen 31 in the recycling bin 3.

The control circuit of the controller can be realized by simple programming of those skilled in the art, and the power supply is also commonly known in the art. Therefore, the control method and circuit connection of the present application will not be explained in detail.

[0043] The working principle of the above embodiment is:

[0044] In use, the mineral powder and iron powder screened out of the magnetic separator 2 fall into the front and rear recovery bins 3 through the two discharge ports of the magnetic separator 2, so that the filter screen 31 can filter out the impurities such as sand contained in the iron powder (or mineral powder), thereby effectively improving the purity of the iron powder (or mineral powder). The magnetic separator 2 can filter the impurities contained in the iron powder while screening the iron powder, and the controller controls the two electric push rods 37 to work, so that the two electric push rods 37 can drive the toothed plates 38 to move linearly on the front and rear walls of the recovery bin 3. The two toothed plates 38 move linearly on the top of the two gears 35, and the toothed plates 38 engage with the gears 35, so that the toothed plates 38 can drive the gears 35 to rotate, that is, the gears 35 can drive the rotating rods 33 to rotate, so that the front and rear rotating rods 33 can drive the front and rear top blocks 32 to rotate in the recovery bin 3. During the rotation of the two top blocks 32, the filter screen 31 can be moved upward, and the filter screen 31 can move downward by inertia, that is, the filter screen 31 can slide up and down on the surface of the two groups of T-shaped rods 39, so that the filter screen 31 can be shaken up and down in the recovery bin 3, thereby increasing the filtering efficiency of the filter screen 31 on the iron powder (or mineral powder).

[0045] By rotating the operating block 311, the operating block 311 drives the screw rod 310 to gradually move out of the threaded hole of the T-shaped rod 39, and the above steps are repeated to disassemble the other three operating blocks 311 from the top end of the T-shaped rod 39, that is, the filter screen 31 can be taken out of the recovery bin 3 for replacement.
