Field of the Invention The present invention has a fixed cylindrical screen having a circular cross-sectional shape in a main body portion having a lateral inlet portion and an axial outlet portion, and the main body screens at arbitrary positions. The present invention relates to a filter having a side wall of a substantially spiral shape that is oblique with respect to the inlet part and continuously collects toward the screen from the inlet part to the collecting part to which the extraction pipe is connected.

により流れをスクリーンを通過させる。Fixed screen filters are disclosed, for example, in US Pat. No. 4,276,171. Since the inlet of the body is actually slightly beveled and flanked, the flow to be processed is circular around the screen. Furthermore, since the side wall of the body is arranged obliquely to the screen, the velocity vector of the flow in the annular space between the body side wall and the screen is itself diagonal to the screen, and as a result Is the tangential component,
This tangential component causes the flow to circulate around the screen, carries the debris and solids carried by the flow towards the collector, and the radial component of the velocity vector causes the flow to pass through the screen.

Fixed screen filters of this kind are especially suitable for small or medium waste such as mussels, fish, gravel, twigs, large algae in which the debris or solids to be separated cannot pass through the filter surface in three dimensions 3-10 mm. It is usually satisfactory when it has dimensions.

It has a substantially spiral side wall that is oblique to the fixed screen and continuously tapers toward the screen from the inlet to the collecting part to which the take-out pipe is connected, and the fixed screen is centered on the axis of the screen filter. And a fixed screen filter containing at least one wash manifold along the generatrix of the freely rotatable fixed screen.

処理される流れの速度と同じ程度の回転速度でスクリー
ンの全表面を規則的に且つ周期的に拭掃する。Because of the tangential component of the velocity vector of the flow being processed, the cleaning manifold is regularly and fully rotated by hydrodynamic action. However, at least one vane is preferably attached to the cleaning manifold to assist in this rotation. Therefore, the cleaning manifold used in the present invention does not require a mechanical device for rotationally driving the cleaning manifold.
The entire surface of the screen is regularly and periodically wiped at a rotational speed comparable to the speed of the stream being treated.

ホルドは流れに同伴し、くずや固形物のスクリーンへの
再付着は、これらが収集部に到達するまで防止される。With each rotation of the wash manifold, debris and solids are swept away by the wash water and are therefore carried away from the screen and thus returned intact in the suspension of the incoming stream. Since the cleaning manifold rotates at the same speed as the incoming flow, the cleaning manifold entrains the flow and prevents debris and solids from reattaching to the screen until they reach the collector. To be done.

The same applies to two-dimensional and three-dimensional debris and solids such as leaves. Therefore, if necessary, change the mesh size to 3
It is possible to reduce it to less than mm.

In order to adopt a cleaning action, the fixed screen filter according to the invention can successfully handle larger amounts of debris and solids.

The fixed screen filter of the present invention can deal with a large amount of debris and solids without being saturated. Due to the rotation imparted to the incoming flow and thus the similar rotational speed imparted to the cleaning manifold, the fixed screen filter according to the invention has the advantages of a fixed screen filter of that kind and of a filter with an internally rotating cleaning manifold. Demonstrate a harmonious combination with.
