[0037] In this application, the nickel ore is passed into the inner cylinder 2 , first through the first washing cylinder section 21 , the washing piece 5 spray water to clean the mud ore coated on the gravel , and from the first grid section 22 to the outer cylinder, most of the mud ore with water through the grille of the first grid section 22 leakage into the outer cylinder 3 ; The gravel attached with the remaining mud ore enters the second washing cylinder section 23 for ore washing, and the washing piece 5 sprays out water to clean the mud ore coated on the gravel , and rows from the second grid section 24 to the outer cylinder . This application adopts two sets of washing cylinder section and the middle grid section connection, so that the ore material goes through the process of primary screening and fine screening, which can ef fectively improve the washing ef fect .

[0038] In this embodiment , the riser 1 is fixed on a reliable ground, and a rotating bearing is arranged between the riser 1 and the inner cylinder 2 . The rotating bearing has a first part capable of relative rotation and a second part , and the first part is fixed with the riser 1 and the second part is fixed with the inner cylinder 2 . The rotating bearing is used to reali ze the rotating connection between the inner cylinder 2 and the vertical frame 1 .

[0039] In order to avoid the ef fect of the rotating bearing on the first grid section 22 and the second grid section 24 to discharge slurry, the second part of the rotating bearing is fixed with the second washing barrel section 23 .

[0040] In this embodiment , in order to make the ore material move in the inner cylinder 2 , the inner cylinder 2 is tilted, the first grid section 22 is slightly higher than the second grid section 24 , the first washing cylinder section 21 open end is the feed port , the second grid section 24 open end is the gravel row outlet , that is , the first washing cylinder section 21 away from the first grid section 22 end is the feed port , One end of the second grid section 24 away from the second washing tube section 23 is the gravel discharge outlet .

[0041] In this example , the first grid segment 22 comprises a number of first grid plates 211 and a first fixed ring 212 , which is arranged at intervals around the material transportation direction, and the first fixed ring 212 is fixed with the first grid plate 211 so that all the first grid plates 211 are arranged to form a cylinder .

The mud ore falls into the outer cylinder 3 through the gap between the second grid plate 241 .

[0048] In this example , two outer tubes 3 are arranged on the first grid section 22 and the second grid section 24 , respectively . The bottom of the outer tube 3 is provided with a mud discharge outlet 31 , and the mud falling into the outer tube 3 is discharged through the mud discharge outlet 31 .

[0049] In this embodiment , the driving piece 4 comprises a driver 41 and a driving wheel 42 , the output end of the driver 41 is coaxially fixed with the driving wheel 42 , and the driving wheel 42 is connected with the inner cylinder 2 . The output end of the driver 41 rotates and the inner cylinder 2 is driven to rotate through the driving wheel 42 .

[0050] It should be noted that the driver 41 has a variety of embodiments , in this embodiment , the driver 41 includes a motor, a coupling, and a reducer, and the motor, the coupling, and the reducer are connected in turn to form a rotational output .
