For example, when trying to detect a clogging state from the dehydration state in the gravity dewatering section 11, disturbances due to changes in the properties of the material to be processed, such as the amount of material to be processed or the solid content concentration of the material to be processed, may be detected. Compared to the filter cloth 9, which is easily susceptible to clogging, we have now been able to accurately detect clogging of the filter cloth 9, and based on the clogging detection, we can increase the washing water jet pressure to clean the clogging or issue an alarm. , or filter cloth 9
Automatically take appropriate action such as stopping the rotation of the
The continuation of poor dehydration due to clogging was avoided, and the dehydration process was successfully performed.
