In the method of spraying the cleaning liquid with a watering can and the like, the cleaning liquid flows down from the filter cloth, so that a small amount of the liquid remaining on the filter cloth is used for washing, and most of the used liquid is wasted. Removing the filter cloth and immersing it in the cleaning solution to remove dirt is better than the attached state, but removing the filter cloth takes several hours without difficult work. In addition, in the method of spraying the cleaning liquid or removing the filter cloth and immersing it in the cleaning tank, a large amount of strong acidic or strong alkaline cleaning liquid is sprayed,
When handling a filter cloth with cleaning liquid, it is dangerous because it may adhere to the skin or mist may get into your eyes.

においても有効であることが確認できた。The results are shown in Table-2. In Table 2, as the cleaning agent, the cleaning agent of No. 1 (Table 1) of Example 1 was used. From the results shown in Table-2, it was confirmed that the cleaning agent of the present invention is also effective in an actual dehydrator.
〔発明の効果〕 本発明によれば次のような効果が生じる。 [Effects of the Invention] According to the present invention, the following effects occur.
１） 従来の洗浄剤は、強アルカリ性の溶液のため、脱
水機及び人体に飛散し、装置の腐食とか人体への危険性
があったが、本発明では増粘剤を添加するのでろ布洗浄
剤の飛散が防止でき安全性が高まった。1) Since the conventional cleaning agent is a strongly alkaline solution, it scatters on the dehydrator and the human body, and there is a risk of corrosion of the device and the human body. However, in the present invention, since a thickener is added, the filter cloth is cleaned. The dispersion of the agent was prevented and safety was improved.
２） 従来の溶液タイプの洗浄剤は洗浄剤の大部分が流
れ落ちていたが、増粘剤の添加によってろ布に洗浄剤を
保持でき、使用する液量を減らすことができ経済的であ
る。2) Most of the conventional cleaning agents of the solution type flowed down, but by adding a thickening agent, the cleaning agent can be retained on the filter cloth and the amount of liquid used can be reduced, which is economical.
３） ベルトプレス脱水機の場合、固定された匡型部材
を用いてろ布上に塗布して行くため、塗布は自動的に行
なわれ、また、圧搾部でろ布洗浄剤がもう一方のろ布に
転写するため塗布時間が短くなった。塗布後30〜60分前
後で、脱水機備えつけのろ布洗浄ノズルで水洗いをし
て、洗浄剤を洗い落すことができ、従来の洗浄方法にく
らべて作業か楽になり、作業人員・作業時間ともに大幅
に削減することができる。3) In the case of a belt press dewatering machine, since the filter cloth is applied on the filter cloth using a fixed box-shaped member, the application is performed automatically, and the filter cloth cleaning agent is applied to the other filter cloth at the pressing section. Application time was shortened due to transfer. About 30 to 60 minutes after application, you can wash off the cleaning agent by washing with a filter cloth washing nozzle equipped with a dehydrator, making it easier or easier to work than conventional cleaning methods It can be reduced significantly.
