DETAILED DESCRIPTION

[0031] As Figs. 1-3As shown, the sludge hydraulic dewatering filter cloth servo differential correction mechanism of the embodiment comprises an anti-wrinkle roller group 200; the anti-wrinkle roller group 200 comprises coaxially arranged first half shaft 201 and second half shaft 202;

[0032] The first half shaft 201 and the second half shaft 202 are independently rotatably arranged;

[0033] The anti-wrinkle roller group 200 is in pressure contact with the front moving filter cloth;

[0034] The outer sidewalls of the first half shaft 201 and the second half shaft 202 are conical shafts.
