[0029] Reference Figure 1 As shown, a mixed ore raw material screening device in a preferred embodiment of the utility model comprises a screening box 1, a magnetic separation component 2 is connected to the outside of the screening box 1, a stirring component 3 is connected to the inside of the screening box 1, and a screening component 4 is connected to the inside of the screening box 1;

[0030] Reference Figure 1-Figure 4 As shown, the magnetic separation component 2 includes a pair of electromagnets 201, which are both movably connected to the screening box 1, and the pair of electromagnets 201 extend to the interior of the screening box 1. The outside of the electromagnet 201 is fixedly connected to a power cord 202, the front and rear ends of the electromagnet 201 are fixedly connected to a limit plate 203, and the left end of the screening box 1 is fixedly connected to a PLC controller 204.

[0031] By setting the electromagnet 201, the PLC controller 204 is used to control whether the power line 202 is energized, thereby controlling the energization of the electromagnet 201. When the electromagnet 201 is energized, the electromagnet 201 will adsorb the magnetic ore contained in the ore that has not been screened in the screening box 1 onto the electromagnet 201, and then use the servo motor 206 to finally drive the two electromagnets 201 to rotate outward, and then the electromagnet 201 is powered off, so that the magnetic ore on the electromagnet 201 can be removed, which is convenient for first distinguishing and screening the particle size of non-magnetic ore, and then screening the particle size of magnetic ore, so as to facilitate the classification of ores of the same particle size and different types in the later stage.

[0032] Reference Figure 1-Figure 4 As shown, the magnetic separation component 2 also includes a transmission box 205, which is fixedly connected to the front end of the screening box 1. The front end of the transmission box 205 is fixedly connected to a servo motor 206, and the rear end of the output end of the servo motor 206 is fixedly connected to a transmission shaft 207.

[0033] By setting up the magnetic separation component 2, the servo motor 206 can eventually drive the left and right electromagnets 201 to rotate in opposite directions under the action of the internal parts of the transmission box 205, which is convenient for controlling the direction of the electromagnet 201 and facilitating the magnetic separation of magnetic ores.

[0034] Reference Figure 1-Figure 4 As shown, the outside of the transmission shaft 207 is fixedly connected to a pulley 208, the inside of the transmission box 205 is rotatably connected to a driven shaft 209, the outside of the driven shaft 209 is fixedly connected to a pulley 210, and the outsides of the pulleys 1 208 and 210 are rotatably connected to a transmission belt 211.

[0035] Reference Figure 1 As shown, the outside of the driven shaft 209 is fixedly connected to a driving gear 212, the right end of the driving gear 212 is meshedly connected to a driven gear 213, the inside of the transmission box 205 is rotatably connected to a rotating shaft 214, the driven gear 213 is fixedly connected to the rotating shaft 214, and the rear ends of the transmission shaft 207 and the rotating shaft 214 are fixedly connected to the limit plate 203.

[0036] The servo motor 1 206 drives the transmission shaft 1 207 to rotate, thereby driving the pulley 1 208, the transmission belt 211, and the pulley 210 to rotate, and then drives the driven shaft 209, the driving gear 212 and the driven gear 213, and the rotating shaft 214 to rotate. Since the two pulleys have the same direction of rotation, the driving gear 212 and the driven gear 213 have opposite directions of rotation, so the transmission shaft 1 207 and the rotating shaft 214 have opposite directions, so that the left and right electromagnets 201 have opposite directions of rotation.

[0037] Reference Figure 1 and Figure 2As shown, the stirring assembly 3 includes a feed hopper 301, which is fixedly connected to the upper end of the screening box 1, and the rear end of the screening box 1 is fixedly connected to a servo motor 2 302, the front end of the output end of the servo motor 2 302 is fixedly connected to a stirring shaft 303, and the outside of the stirring shaft 303 is fixedly connected to a stirring blade 304.

[0038] By setting up the stirring assembly 3, the ore raw materials are added into the screening box 1 through the feed hopper 301, and the servo motor 2 302 drives the stirring shaft 303 and the stirring blades 304 to rotate, so that the ore raw materials can be stirred, so that the magnetic ore can be in contact with the magnetic field of the electromagnet 201 as evenly as possible, so as to facilitate more thorough magnetic separation.

[0040] By setting the receiving plate 307, before the magnetic separation is completed, the receiving plate 307 is in a parallel state with the ground. After the magnetic separation is completed, the servo motor three 305 drives the transmission shaft two 306 and the receiving plate 307 to rotate downward, so that the non-magnetic ore can fall onto the screening net one 401 for screening.

[0045] Specific implementation process: PLC controller 204 is used to control whether power line 202 is powered on or not, thereby controlling the power on of electromagnet 201. At the same time, ore raw materials are added to the inside of screening box 1 by feed hopper 301, and servo motor 2 302 drives stirring shaft 303 and stirring blade 304 to rotate, so that ore raw materials can be stirred, so that magnetic ore can be in contact with the magnetic field of electromagnet 201 as evenly as possible.

[0046] When the electromagnet 201 is powered on, the electromagnet 201 will adsorb the magnetic ore contained in the ore that has not been screened in the screening box 1 onto the electromagnet 201, and then use the servo motor 206 to finally drive both electromagnets 201 to rotate outwards, and then the electromagnet 201 is powered off, so that the magnetic ore on the electromagnet 201 can be removed, which is convenient for first distinguishing and screening the particle size of non-magnetic ore, and then screening the particle size of magnetic ore, which is convenient for the later classification of ores of the same particle size and different types;

[0047] After magnetic separation, the servo motor 305 drives the transmission shaft 2 306 and the receiving plate 307 to rotate downward, so that the non-magnetic ore can fall onto the screening net 1 401;
