[0034] A guide column 201 is provided on the outer side wall of the lower opening of the first material guide trough 2 and the second material guide trough 3 , and a first sliding hole 501 is provided on the opening side wall of the first filter 5 and the second filter 6 . The first sliding hole 501 of the first filter 5 and the second filter 6 cooperates with the guide column 201 .

[0035] A conveying auger 7 is rotatably installed inside the first filter 5 and the second filter 6 , and the graphite remaining in the first material guide trough 2 and the second material guide trough 3 is transported away by the conveying auger 7 .

[0036] like Figure 3 As shown, the first filter 5 and the second filter 6 are open at one end and closed at the other end. The closed end is provided with a second sliding hole 502 , and the second sliding hole 502 is used to avoid the rotating shaft of the conveying auger 7 .

[0037] The first filter 5 and the second filter 6 are fixedly connected via a fixed connecting plate 12 .

[0038] A roller 10 is rotatably mounted at the lower end of the second filter 6 , and a cam 9 is disposed at the lower end of the roller 10 . The cam 9 is fixedly mounted on a rotating shaft 8 , and the rotating shaft 8 is rotatably mounted in the housing 1 .

[0039] A third material guide trough 4 is provided at the lower end of the second filter 6. The upper side of the third material guide trough 4 is a V-shaped structure, and the lower end of the V-shaped structure is a U-shaped trough structure, in which a conveying auger 7 is rotatably installed.
