Due to the special nature of the rotary type dust remover operating close to a river, more than 80% of the parts that make up the device are made of stainless steel. Stainless steel material is applied to the parts. In addition, sufficient rigidity is required, so the dimensions of the members that affect rigidity, including thickness, are applied excessively, resulting in a large weight. As a result, resistance increases during operation, lowering operating efficiency, and production and maintenance are costly and time-consuming, and maintainability is poor. In particular, when the rake blade is damaged, drainage by the pump cannot be smoothly achieved due to inoperability or performance degradation due to interference with other parts, which can cause serious damage to life and property due to flooding. Accordingly, in this study, a carbon material rake was developed to replace the existing stainless steel rake, and research was conducted to improve and optimize the problems of the existing rake.
