The upper end of the limiting ring (12) is inlaid with a plurality of contact balls (20), and the lower end of the limiting ring (12) is provided with a plurality of cleaning through holes (21). The upper ends of the cleaning through holes (21) are connected to the grooves where the contact balls (20) are located.

10. A method for mixing chemical materials according to any one of claims 1 to 9, characterized in that: First, the solid raw materials and powdered raw materials to be mixed are put into the mixing inner cylinder (4) from the feed pipe (3), and then the liquid raw materials are added through the liquid adding pipe (16). The liquid raw materials are sprayed into the mixing inner cylinder (4) through the spray holes (18) on the side wall of the liquid spray pipe (13). At the same time, the mixing motor (6) drives the rotating rod (7) to rotate, thereby driving the stirring frame (11) and the pushing spiral piece (14) to rotate. Under the action of the stirring frame (11), the solid raw materials, powdered raw materials and liquid raw materials are mixed. At the same time, under the action of the pushing spiral piece (14), various raw materials are pushed to the mixing inner cylinder (4). The raw materials are crushed into the crushing cone (15) and the crushing outer tube (5) by the cooperation of the crushing cone (15), the crushing strip (19) and the crushing outer tube (5) to prevent the materials from agglomerating when mixed; the mixed materials enter the bottom of the mixing barrel (1); the rotating rod (7) rotates while driving the stirring straight plate (32) and the driving gear (8) to rotate, and the driving gear (8) and the driven gear (10) cooperate to drive the stirring rod (9), the stirring inclined plate 1 (22) and the stirring inclined plate 2 (23) to rotate, and then the stirring inclined plate 1 (22) and the stirring inclined plate 2 (23) are used to rotate. The mixing inclined plate 2 (23) and the mixing straight plate (32) cooperate to further mix the mixed materials; when the rotating rod (7) rotates, the active gear disc (29) is also driven to rotate, and the active gear disc (29) drives the driven gear disc (28) through the chain. As the driven gear disc (28) rotates, the lifting rod (27) and the lifting spiral (30) rotate. Under the action of the lifting spiral (30), the material entering the lifting cylinder from the connecting pipe 1 (25) is lifted to the position of the connecting pipe 2 (26), and then re-introduced into the mixing cylinder (1) through the connecting pipe 2 (26). The material at the bottom of the mixing drum (1) is lifted to the top by the action of the material lifting mechanism, and the mixing effect of the device is further improved by the action of the lifting spiral blade (30); while the materials are being mixed, the material is directly added to the mixing drum (1) according to the mixing requirements by using the feed pipe (2); after the materials are mixed, the mixing motor (6) is rotated in the reverse direction, thereby driving the lifting rod (27) and the lifting spiral blade (30) to rotate in the reverse direction, and the lifting spiral blade (30) exerts a downward force on the mixed material, thereby discharging the material from the mixing drum (1) and the lifting drum through the discharge pipe (31).
