求項記載の回転ドラム式濾過装置。[Claims for Utility Model Registration] (1) A rotating drum that is horizontally arranged to freely rotate, has a screen around its body, and has at least one end opened in a cylindrical shape; A rotary drum comprising: a water supply weir that is arranged facing the end of a cylindrical opening and has a water inlet that opens toward the inside of the cylindrical opening; and a water supply channel that communicates with the water inlet of the water supply weir. In the type filtration device, an end face sliding type seal member having an inverted cross-sectional shape opening in the outer radial direction is mounted on the outer circumferential surface of the cylindrical opening end of the rotary drum, and the water supply weir A cylindrical seal receiving part is provided on the surface facing the rotating drum, protruding concentrically toward the outer periphery of the cylindrical end of the rotating drum, and having a square groove around the inner diameter surface. An end face sliding type seal member on the outer periphery of the end of the rotating drum is slidably and rotatably fitted into the rectangular groove of the cylindrical seal receiving part of the water supply weir, and the inner diameter surface A rotating drum characterized in that at least two liquid passage ports are provided to communicate between the bottom of the square groove provided around the drum and the outside, and a liquid supply/drainage means for circulating cooling liquid is communicated with these liquid passage ports. type filtration device. (2) On the inner peripheral surface of the cylindrical opening end of the rotating drum, an annular sloped surface part whose diameter decreases toward the opening end is formed, while on the surface of the water supply weir facing the rotating drum,
A circular arc along the inner peripheral surface of the lower part of the cylindrical opening end of the rotating drum protrudes into the cylindrical opening, and on the outer peripheral surface opposite to the annular sloped surface on the inner periphery of the cylindrical opening end, there is a circular arc extending toward the tip. A circular arc member having a diameter-reducing arc-shaped sloped surface portion is provided protrudingly, and a cross-sectional shape facing the water supply weir side is provided between the annular sloped surface portion on the inner periphery of the cylindrical end and the circular arc-shaped sloped surface portion of the circular arc member. An arc-shaped seal member having a narrowing wedge shape is provided, and this arc-shaped seal member is connected to and held by a bullet provided at a fixed part on the water supply weir side, so that the rotating drum can move in the rotational direction. 2. The rotating drum type filtration device according to claim 1, wherein the rotary drum type filtration device is restrained and energized toward the water supply weir side.
