Specifically, the magnetic medium net 21 is installed in the material guiding pipe 3, the structure of the magnetic medium net 21 is not described in detail in the prior art, an electromagnet is arranged on the outer peripheral surface of the material guiding pipe 3, the electromagnet comprises an electrified coil 19 and a magnetic track 20, when the electrified coil 19 is electrified, the magnetic track 20 magnetizes the magnetic medium net 21, thereby having adsorption capacity on iron powder, when the electrified coil 19 is not electrified, the magnetic medium net 21 demagnetizes, thereby separating the iron powder from the magnetic medium net 21 and falling, the above is the disclosed prior art, and is not described in detail, wherein, the top opening of the material guiding pipe 3 is a feed inlet 302, the opening corresponding to the feed inlet 302 is an iron powder discharge outlet 303, a powder discharge outlet 304 is obliquely arranged on one side of the iron powder discharge outlet 303, a blocking plate 16 is positioned at the poor part of the iron powder discharge outlet 303 and the powder discharge outlet 304, the iron powder discharge outlet 303 and the powder discharge outlet 304 are alternately conducted by utilizing the rotation of the blocking plate 16, that is, when the iron powder outlet 303 is conducted, the iron powder outlet 304 is closed, when the iron powder outlet 304 is conducted, the iron powder outlet 303 is closed, whether the iron powder outlet 304 is conducted or the iron powder outlet 303 is conducted, the blocking plate 16 is in an inclined state, the iron powder outlet 304 is conducted in an initial state (as shown in fig. 6 and 7), at the moment, the electrified coil 19 is electrified to magnetize the magnetic medium net 21, powder is poured into the material guide pipe 3 from the material inlet 302, the powder passes through the magnetic medium net 21 and falls on the blocking plate 16, the iron powder part contained in the powder is adsorbed by the magnetic medium net 21 and does not fall, the powder passing through the magnetic medium net 21 can slide into the iron powder outlet 304 along the blocking plate 16 to be discharged, and the iron powder which is not adsorbed by the magnetic medium net 21 in the powder can not slide into the iron powder outlet 304 together with the powder, after the powder is completely discharged, the blocking plate 16 is rotated to enable the iron powder discharge hole 303 to be conducted to the powder discharge hole 304 to be closed, the energizing coil 19 is stopped from being energized to demagnetize the magnetic medium net 21, at the moment, the iron powder adsorbed on the magnetic medium net 21 falls into the iron powder discharge hole 303 to be discharged under the action of gravity, and meanwhile, the iron powder adsorbed on the blocking plate 16 is cleaned into the iron powder discharge hole 303. In the prior art, when a large amount of powder containing iron powder passes through the magnetic medium net, the magnetic medium net is difficult to realize the adsorption of all the iron powder at one time, because the iron powder is wrapped by the powder and even adhered, all the iron powder and the powder pass through the magnetic medium net together and cannot be adsorbed by the magnetic medium net, and the iron powder passing through the magnetic medium net can be directly discharged from a discharge port together with the powder, so that further iron removal cannot be realized, and the separation effect of the iron powder and the powder is reduced.
In this embodiment, the blocking plate 16 with adsorption capability is rotatably arranged, so that the iron powder outlet 303 and the powder outlet 304 can be alternately conducted when the blocking plate 16 is rotated, when the powder outlet 304 is conducted, powder passing through the magnetic medium net 21 can fall on the blocking plate 16, at the moment, if the powder contains iron powder which is not adsorbed by the magnetic medium net 21, the powder can be adsorbed on the blocking plate 16 and cannot slide into the powder outlet 304, and the blocking plate 16 does not have adsorption capability on the powder, so that the powder can slide into the powder outlet 304 along the blocking plate 16 to be discharged, and therefore, the discharged powder is purer. It can be seen that the plugging plate 16 not only has the function of plugging the iron powder discharge port 303 and the powder discharge port 304, but also has the function of further removing iron.
Further, when the blocking plate 16 is rotated to conduct the iron powder outlet 303, the blocking plate 16 is in a demagnetized state so that the iron powder adsorbed on the blocking plate 16 enters the iron powder outlet 303, and therefore the operation of independently cleaning the iron powder adsorbed on the blocking plate 16 into the iron powder outlet 303 can be omitted, and the magnetic separation mechanism is more intelligent and convenient.

When the plugging plate 16 rotates anticlockwise (as shown in fig. 8), the plugging plate 16 is staggered from the fixed inclined plate 17, and the gap between the left end of the plugging plate 16 and the inner wall of the material guiding pipe 3 is increased, so that the iron powder can flow into the iron powder discharging hole 303 along the plugging plate 16 and after passing through the gap between the plugging plate 16 and the inner wall of the material guiding pipe 3, and the iron powder cannot enter the powder discharging hole 304 beyond the plugging plate 16 due to the inclination of the plugging plate 16.
In this embodiment, the plugging plate 16 is rotatably disposed in the material guiding tube 3 through the first rotating shaft 24, the inner cavity of the material guiding tube 3 and the inner cavity of the material discharging tube 6 are both rectangular, and the widths of the front side surface of the plugging plate 16 and the front side surface of the inner cavity of the material guiding tube 3 and the front side surface of the inner cavity of the material discharging tube 6 are the same, and the rear side surface of the plugging plate 16 and the rear side surface of the inner cavity of the material guiding tube 3 and the rear side surface of the inner cavity of the material discharging tube 6 are in sliding fit, so that the plugging plate 16 has a better plugging effect on the powder material outlet 304 and the iron powder material outlet 303.
