The treatment of several common problems after repair of belt filter press

      First, the improper installation position of the belt press roller is easy to appear after the overhaul of the sludge dewatering machine. After the overhaul of the sludge dewatering machine, it is necessary to check and correct all the pressing rollers in the horizontal and parallel directions.

For parallel direction correction, the frame of the mud outlet can be selected as the datum plane, and the distance between the center point of the left and right supporting bearings of each press roller and the datum plane can be measured. The horizontal distance deviation of the center point of the left and right bearing of a single press roller should be less than 1mm, and the cumulative horizontal distance deviation of all press rollers should be less than 5mm.

For horizontal direction correction, the principle of U-tube can be applied, and a simple measuring tool can be made by using water injection transparent rubber hose for detection. The vertical distance deviation of the center point of left and right bearing of the press roller should be less than or equal to 1mm.

Two, the belt filter press roller at both ends of the supporting bearing fault should be strengthened in operation, inspection and maintenance of the bearing should be strengthened, and the problem should be replaced in time to prevent the expansion of the fault (wear of the roller shaft and deviation of the net belt).

Three, the squeezing roller rubber roller surface precision problems appeared in the press roll roll surface damage or hang plastic bags/plastic repair again after processing, rubber roller surface damage, cylindrical roller surface processing irregular ellipse, roller cone, etc, should be in roll bread glue/hanging plastic processing, precision work using the lathe processing, press roll roundness tolerance grade should refer to 10th level, such as: outer diameter is 250 mm – 315 mm press roll roundness tolerance should be 52 microns or less , the alignment tolerance grade should reference level 9, such as: axial length is 2000 mm to 3150 mm of squeezing roller alignment tolerance shall be 300 microns or less.
