PROBLEM TO BE SOLVED: To provide a filter device capable of removing captured objects inside a filter element, by an axial flow inside the filter element.SOLUTION: The filter device includes: a casing 1; a first partition wall 2 for partitioning the inside of the casing into a first raw fluid chamber 9a for storing fluid before filtration, and a filtrate chamber 10 for storing fluid after filtration; cylindrical filter elements 3a, 3b which are provided in the filtrate chamber, one end of each of which is held by the first partition wall so that the inside communicates with the first raw fluid chamber, for filtering fluid passing from the inside toward the outside; a second partition wall 4 provided at the other end side of the filter elements, for forming a second raw fluid chamber communicating with the first raw fluid chamber; a pipe 5 for cleaning provided at an end of at least one of the filter elements, for making fluid flow from the raw fluid chamber in an axial direction of the filter element, and cleaning the filter element; and a cleaning fluid drain pipe 6 for discharging captured objects to the outside. At the filter element 3b one end of which is connected to the pipe 5 for cleaning, the other end always opens to the raw fluid chamber 9a.

    【課題】 フィルターエレメント内部の捕捉物をフィルターエレメント内部の軸方向流により除去できる濾過装置を提供する。【解決手段】 ケーシング1と、その内部を、濾過前の流体が収容される第1の原液室9aと濾過後の流体が収容される濾液室10とに隔離する第1の隔壁2と、内部が第1の原液室と連通して濾液室内に設けられ、内側から外側に向けて流体が通過して濾過する筒状のフィルターエレメント3a,3bと、フィルターエレメントの他方の端部側に設けられ、第1の原液室と連通する第2の原液室を形成する第2の隔壁4と、フィルターエレメントの少なくとも一方の端部側に接続され、原液室からフィルターエレメントの軸方向に流体を流して洗浄する洗浄用パイプ5と、捕捉物を外部へ排出する洗浄流体ドレンパイプ6と、を備え、洗浄用パイプ5に接続されているフィルターエレメント3bの他方の端部は、常に原液室9aに開口しているものである。【選択図】図5
