ができる。Effects of the invention According to the above-mentioned configuration of the invention, the liquid to be separated is supplied into the end of the cylindrical body opposite to the solid matter discharge port. , it is possible to almost eliminate the disturbance effect of the settled solids, and the separated liquid is passed through the cylindrical body from a place between the cylindrical part and the conical part of the cylindrical body, that is, between the settling area and the dehydration area. Because it is discharged
Unlike in the past, the separated water does not flow in the opposite direction to the solids, causing the solids to be suspended again, and complete separation and dehydration can therefore be achieved. Furthermore, by adjusting the height of the opening for liquid passage using the weir plate, the cleanliness of the separated water can be adjusted.
