AUTOMATIC FILTERING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an automatic filtering apparatus capable of dealing with clogging in a filter element on the way of filtering. SOLUTION: The automatic filtering apparatus is equipped with an original solution containing section which has one or more containers containing an original solution to be filtered that is a filtering object; the filter medium which filters the original solution to be filtered; an original solution channel which connects the filter medium to the container of the original solution containing section; a solution supplying means which supplies the filter medium with the original solution to be filtered through the original solution channel; a filtered solution containing section which has one or more containers containing a filtered solution passing through the filter medium; a filtrate channel which connects the filter element to the container of the filtrate containing section; and a pressure sensor disposed on the way of the original solution channel. In the automatic filtering apparatus, the solution supplying means is disposed on the upstream side of the pressure sensor, and a filter medium exchanging means is installed, which exchanges the filter medium when a pressure value detected by the pressure sensor becomes equal to or more than a prescribed value.
