FILTER CLOTH CLEANING METHOD OF FILTER PRESS

To provide a filter cloth cleaning method of a filter press which can clean an entire surface of a filter cloth with high detergency even if a filter press cleans the filter cloth in a filter chamber.SOLUTION: A filter cloth cleaning method of a filter press which cleans a filter cloth 21 disposed in a filter chamber formed between filter plates 19 includes: a step in which the filter plates 19 are closed to form the filter chamber between the filter plates 19; a step in which a cleaning fluid and an impact body 8 are supplied from an undiluted solution supply hole 24 to the filter chamber; a step in which air is introduced from a communication port 26c to stir the filter chamber; a step in which the filter plates 19 are opened to discharge the cleaning fluid and the impact body 8 from the filter chamber; and a step in which the cleaning fluid and the impact body 8 are separated to recover the impact body 8.SELECTED DRAWING: Figure 7 【課題】ろ過室内でろ布を洗浄するフィルタープレスであっても、ろ布の全面を高い洗浄力で洗浄することができるフィルタープレスのろ布洗浄方法の提供。【解決手段】複数のろ板１９間に形成されるろ過室に配置されたろ布２１を洗浄するフィルタープレスのろ布洗浄方法において、複数のろ板１９を閉板してろ板１９間にろ過室を形成する工程と、ろ過室へ原液供給孔２４より洗浄液と衝撃体８を供給する工程と、エアーを連通口２６ｃから導入することによりろ過室を攪拌する工程と、複数のろ板１９を開板してろ過室から洗浄液と衝撃体８を排出する工程と、洗浄液と衝撃体８を分離して衝撃体８を回収する工程と、を備えるフィルタープレスのろ布洗浄方法。【選択図】図７
