AUTOMATIC FILTRATION DEVICE

PROBLEM TO BE SOLVED: To provide an automatic filtration device capable of continuing a filtration work by automatically changing a used filter medium including a filtration stock solution to a new one without spilling the stock solution or polluting a filter medium to be next used even if some amount of the stock solution is left on the filter medium.SOLUTION: An automatic filtration device 1 includes: a filter 5 which has the first and second cylinders 5a and 5b holding a cassette 9 retaining a filter medium 8 in between and filtrates a filtration stock solution in the first cylinder 5a by sending to the second cylinder 5b through the filter medium 8 retained in the cassette 9; a cassette feeding unit housing and feeding plural cassettes 9; and a cassette detachable mechanism which detaches the cassette 9 held between the first and second cylinders 5a and 5b and installs the cassette 9 fed from the cassette feeding unit between the first and second cylinders 5a and 5b to be held between the cylinders 5a and 5b.SELECTED DRAWING: Figure 1 【課題】濾過材上に多少の濾過原液が残っていた場合であっても、濾過原液を溢したり、次に濾過に用いる濾過材を汚染したりすることなく、自動的に濾過原液ごと濾過材を交換して濾過作業を行うことが可能な自動濾過装置の提供。【解決手段】濾過材８を保持したカセット９を挟持する第１筒５ａおよび第２筒５ｂを有し、第１筒５ａ内の濾過原液をカセット９に保持された濾過材８を通して第２筒５ｂへ送ることにより濾過する濾過器５と、カセット９を複数収容し、供給するカセット供給装置と、第１筒５ａおよび第２筒５ｂに挟持されたカセット９を取り外すとともに、カセット供給装置から供給されたカセット９を第１筒５ａと第２筒５ｂとの間へ取り付け、第１筒５ａおよび第２筒５ｂに挟持させるカセット脱着機構とを含む自動濾過装置１である。【選択図】図１
