As a professional manufacturer of sludge dewatering equipment with over 20 years’ experience, it’s necessary for BOEEP to share with you the solutions to the problems of belt filter press.
Problem -1: Excessive moisture content of sludge cake
| Main cause | Solutions |
| Too little strain on the filter belt | Strengthen strain force, generally no greater than 0.5MPa |
| Filter belt speed is too fast | Reduce speed, generally no less than 3m/min |
| Sludge supply is not uniform | Adjust |
Problem-2: Sludge cake is too thin
| Main cause | Solutions |
| Filter belt tension is too high | Reducing the tension, generally no less than 0.3MPa |
| Filter belt speed is too fast | Reduce speed, generally no less than 3m/min |
| Too little dosage | Increase dosage |
| Blocking | Clean up |
| Too little sludge intake | Adjust |
Problem-3: Sludge cake is too thick
| Main cause | Solutions |
| Too little strain on the filter belt | Strengthen strain force, generally no greater than 0.5MPa |
| Filter belt speed is too slow | Increase speed, generally no greater than 8m/min |
| Too much dosage | Reduce dosage |
| Too much sludge intake | Adjust |
Problem-4: Too little treating capacity
| Main cause | Solutions |
| Filter belt tension is too high | Reducing the tension, generally no less than 0.3MPa |
| Filter belt speed is too slow | Increase speed, generally no greater than 8m/min |
| Too little dosage | Increase dosage |
| Too much dosage | Adjust |
| Blocking | Clean up |
| Too little sludge intake | Adjust |
Problem-5: It is difficult to rinse the filter belt.
| Main cause | Solutions |
| Too little strain on the filter belt | Strengthen strain force, generally no greater than 0.5MPa |
| Filter belt speed is too slow | Increase speed, generally no greater than 8m/min |
| Failure of backwash pump | Overhaul |
| Blockage of flushing mechanism | Clean up |
Problem-6: Leakage
| Main cause | Solutions |
| Connector is not sealed | Repair or replacement |
| Damage of cylinder block or piston ring | Repair or replacement |
| Valve failure damage | Repair or replacement |
Problem-7: Vibration or abnormal noise
| Main cause | Solutions |
| Bearing damage | Replacet |
| Axis balance error is large | Readjust |
| Limit switch failure | Inspect, repair and replace |
| Friction or collision of moving parts | Readjust |
| Loose connection | Readjust |
Problem-8: Deviation of filter belt
| Main cause | Solutions |
| Uneven material | Adjust |
| Rectifying system failure | Inspect |
| Large roll system error | Adjust |
| Cylinder air leakage | Inspect and repair |
Problem-9: Filter belt damage
| Main cause | Solutions |
| Long time use, aging | Replace |
| Friction of filter belt | Repair and replace |
| Uneven interface | Reconnect |
Problem-10: Reducer is not working properly.
Problem-11: The motor is not working properly.
