とかでさる。According to the scraping device 1 having the above configuration, the sensor 19 detects the interface position of the sludge 7, that is, the accumulation m of the sludge 7, and the operation of the motor 9 is automatically started according to the detection result.・After processing is completed, operation is stopped and the machine goes into standby mode. Therefore, even if the quality of the inflow water 1 changes, the operation interval will automatically change to follow the sludge 7 deposition process, preventing unnecessary operation. Compared to continuous operation or intermittent operation regardless of the K jil of l mud 7, running costs can be significantly reduced and the life of consumable parts can be extended. , and to reduce maintenance costs.
