[0024] The filtering structure includes a guide plate 12 fixed to the inner wall of the storage barrel 1, an arc-shaped rib hoop 16 is fixedly connected to the guide plate 12, a longitudinal rib rod 18 is fixedly connected between the arc-shaped rib hoop 16 and the guide plate 12, a transverse rib rod 17 is fixedly connected between the longitudinal rib rod 18 and the arc-shaped rib hoop 16, and a plurality of transverse rib rods 17 and longitudinal rib rods 18 are evenly spaced.

[0025] When in use, the transverse ribs 17 and the longitudinal ribs 18 can quickly crush the agglomerated aluminum oxide powder, filter the agglomerated aluminum oxide powder, and separate the iron powder filtered from the alumina powder.

[0026] The transverse ribs 17 and the longitudinal ribs 18 are elastic, and are distributed in a cross shape. The inner wall of the arc-shaped rib hoop 16 is fixedly connected to the inner wall of the storage barrel 1 .

[0027] An iron powder discharge pipe 3 is fixedly connected to the storage barrel 1 near the guide plate 12, and an air suction port 10 is provided between the storage barrel 1 and the exhaust funnel 2, and the exhaust funnel 2 is connected to the inner cavity of the storage barrel 1 through the air suction port 10;

[0028] After the agglomerated alumina powder filters the iron powder, the iron powder in the alumina powder will be discharged through the iron powder discharge pipe 3 . When the guide plate 12 is in use, the iron powder filtered by the alumina powder can be discharged through the iron powder discharge pipe 3 .

[0029] The top of the inner wall of the cavity of the storage barrel 1 is fixedly connected with a rotating seat 9, and the inside of the rotating seat 9 is rotatably connected with a transmission rod 14, and the conveying blade 11 and the crushing rod 13 are fixedly connected to the transmission rod 14, and the conveying blade 11 and the crushing rod 13 are distributed at equal intervals with the transmission rod 14 as the center. The bottom of the storage barrel 1 is fixedly connected with a storage bucket 7, and the bottom of the storage bucket 7 is fixedly connected with a stirring motor 6, and the output end of the stirring motor 6 passes through the storage barrel 1 and is fixedly connected to the transmission rod 14;

[0030] When the output shaft of the stirring motor 6 is in use, the transmission rod 14 can drive the conveying blade 11 and the crushing rod 13 to rotate. At this time, the conveying blade 11 can discharge part of the alumina powder through the suction funnel 2. When the crushing rod 13 is in use, it can crush the agglomerated alumina powder and realize the filtration of the iron powder in the alumina powder through the transverse rib rod 17 and the longitudinal rib rod 18.

[0031] A delivery pipe 8 is fixedly connected between the delivery blade 11 and the crushing rod 13 on the storage barrel 1, and the delivery pipe 8 is arranged opposite to the iron powder discharge pipe 3;

[0032] The conveying pipe 8 can convey the alumina powder to the interior of the storage barrel 1. At this time, the alumina powder can pass through the gap between the transverse ribs 17 and the longitudinal ribs 18 and enter the interior of the storage bucket 7. The agglomerated alumina powder will collide with the transverse ribs 17 and the longitudinal ribs 18. Since the transverse ribs 17 and the longitudinal ribs 18 are elastic, the alumina powder can be easily crushed on the transverse ribs 17 and the longitudinal ribs 18.

[0033] The inner cavity of the storage barrel 1 is connected to the inner cavity of the storage bucket 7. The storage bucket 7 is a bucket-shaped structure. The inner wall of the storage bucket 7 is tilted and fixedly connected with an inclined plate 15. The portion of the storage bucket 7 close to the inclined plate 15 is fixedly connected with an aluminum powder discharge pipe 4. The lower part of the storage bucket 7 is fixedly connected with a support frame 5.

[0034] The aluminum oxide powder filtered by the transverse ribs 17 and the longitudinal ribs 18 will be transported to the aluminum powder discharge pipe 4 under the guidance of the inclined plate 15, so that the aluminum oxide powder that has filtered the iron powder can be discharged to the outside.

[0035] The iron removal structure includes an iron powder storage box 19 detachably connected to a portion of the storage bucket 1 near the storage bucket 7, a connecting hole 24 is provided on the iron powder storage box 19, the iron powder storage box 19 is connected to the inner cavity of the storage bucket 1 through the connecting hole 24, a rotating motor 26 is detachably connected to the top surface of the arc-shaped reinforcement hoop 16, an electromagnet 25 is detachably connected to a portion of the iron powder storage box 19 near the storage bucket 1, a discharge funnel 20 is fixedly connected to the bottom surface of the iron powder storage box 19, the inner cavity of the discharge funnel 20 is connected to the inner cavity of the iron powder storage box 19, a rotating rod 21 is rotatably connected to the inside of the iron powder storage box 19, and iron plates 23 are distributed around the rotating rod 21 inside the iron powder storage box 19, and the iron plates 23 are fixedly connected to the rotating rod 21 through a connecting support rod 22;

[0036] When the alumina powder filtered by the transverse ribs 17 and the longitudinal ribs 18 is transported to the inclined plate 15, the staff starts the rotating motor 26. The output end of the rotating motor 26 can drive the iron plate 23 to rotate through the rotating rod 21. When the iron plate 23 is located directly below the electromagnet 25, the electromagnet 25 can transmit magnetism to the iron plate 23. At this time, the magnetic iron plate 23 will absorb the iron powder in the alumina powder. Then, the output end of the rotating motor 26 can drive the iron plate 23 to continue rotating through the rotating rod 21. The iron plate 23 located above the discharge funnel 20 will lose its magnetism. At this time, the iron powder on the iron plate 23 will be discharged through the discharge funnel 20, thereby realizing the filtration of iron powder in the alumina powder.

[0037] Working principle: When the device is actually used, the staff will place the support frame 5 in a suitable position, and then the staff will connect the stirring motor 6 to an external power supply. The conveying pipe 8 can convey the alumina powder to the interior of the storage barrel 1. At this time, the alumina powder can pass through the gap between the transverse ribs 17 and the longitudinal ribs 18 and enter the interior of the storage bucket 7. The agglomerated alumina powder will collide with the transverse ribs 17 and the longitudinal ribs 18. Since the transverse ribs 17 and the longitudinal ribs 18 are elastic, the alumina powder can be easily crushed on the transverse ribs 17 and the longitudinal ribs 18. When the output shaft of the stirring motor 6 is in use, the transmission rod 14 can drive the conveying blade 11 and the crushing rod 13 to rotate. At this time, the conveying blade 11 can discharge part of the alumina powder through the exhaust funnel 2. When the crushing rod 13 is in use, it can crush the agglomerated alumina powder, so that the iron powder in the alumina powder can pass through the transverse ribs 17 and the longitudinal ribs 18. Filtration, the alumina powder filtered by the transverse ribs 17 and the longitudinal ribs 18 will be transported to the aluminum powder discharge pipe 4 under the guidance of the inclined plate 15, so that the alumina powder that has filtered the iron powder can be discharged to the outside, so that multi-stage filtration treatment of the alumina powder can be achieved. When the alumina powder filtered by the transverse ribs 17 and the longitudinal ribs 18 is transported to the inclined plate 15, the staff starts the rotating motor 26 to work, and the output end of the rotating motor 26 can drive the iron plate 23 to rotate through the rotating rod 21. When the iron plate 23 is located directly below the electromagnet 25, the electromagnet 25 can transmit magnetism to the iron plate 23. At this time, the magnetic iron plate 23 will absorb the iron powder in the alumina powder. Then, the output end of the rotating motor 26 can drive the iron plate 23 to continue to rotate through the rotating rod 21, and the iron plate 23 located above the discharge funnel 20 will lose its magnetism. At this time, the iron powder on the iron plate 23 will be discharged through the discharge funnel 20, so that the iron powder in the alumina powder can be filtered.
