的に説明する。Further, when the inner and outer screens are clogged by such a filtering operation, the pressure detector is operated in the intermediate chamber.
The pressure can be detected, the supply pump can be started, and the clogging can be removed by washing with high pressure fluid such as high pressure water.
At this time, since the high-pressure fluid is blown from the direction opposite to the filtration direction, clogging is not promoted unlike the conventional scraper. Further, since the screen drum is rotating during this cleaning, the jet nozzle can be fixed and provided for automatic cleaning. Also,
This washing operation can be performed while continuing the filtration operation depending on the purpose of filtration. Hereinafter, the present invention will be specifically described with reference to the drawings.

It can be resolved. In cleaning the screen, according to the present invention, the outer cylinder 1a and the inner cylinder 1b rotate, so that the screen 1e can be uniformly and automatically cleaned only by sending the high-pressure fluid. In addition, when cleaning the screen 1e, it is needless to say that the inner and outer cylinders may not be simultaneously cleaned, but may be separately cleaned. In addition, the high-pressure fluid source may be separated, and the cleaning fluid may be a fluid of a different type from inside and outside, For example, the outer cylinder 1a
May be washed with high pressure water, and the inner cylinder 1b may be washed with high pressure air.

The filtration operation may be interrupted once for washing. That is, when the stock solution such as sludge is pressed and pushed, and the liquid content is separated and concentrated by the inner and outer screens 1e, there is less possibility that the wash water will enter the concentrated stock solution. This is because the cleaning fluid is mixed in the filtrate when it is intended. As for the time for cleaning the screen 1e, the pressure detector 13 of the intermediate chamber 1d as shown in FIG.
The automatic operation is possible when the is activated.
