Description

  The present invention refers to a mixture of raw seaweed and seawater (a mixture of raw seaweed and seawater; hereinafter referred to as a raw seaweed mixed liquid) to foreign matter (trash, shrimp, small shellfish, sea bream, and other contaminants. The present invention relates to a selection casing and a surface pressure device for a rotating plate in a raw seaweed foreign matter separation section in a raw seaweed mixed liquid tank for separating and removing.

  As this type of foreign matter separation and removal apparatus, there is a foreign seaweed foreign matter separation and removal apparatus disclosed in Japanese Patent Laid-Open No. 8-14037. In this invention, a rotating plate is fitted in the inner peripheral edge of the annular frame plate portion of the cylindrical mixed liquid tank through a slight clearance in a substantially flush state, and this rotating plate is appropriately driven around the axis. It is possible to rotate by means, and this cylindrical mixed liquid tank is provided with a foreign matter discharge port. By using the specific gravity difference and centrifugal force, the foreign matter is separated and removed efficiently, and the clogging of the clearance is reduced. It is explained that there is such an effect.

  However, the present invention has a structure in which a rotating plate is fitted into the inner peripheral edge of the annular frame plate portion via a clearance, and the rotating plate is fixed to the rotating shaft. Therefore, since the raising / lowering of the rotating plate and / or the expansion / contraction of the clearance cannot be changed in consideration of the clogging and the situation of foreign matter / raw seaweed, there is a problem that the usability is inferior. In the present invention, the annular frame plate portion is composed of two parts, and the clearance is adjusted through the adjustment of the two parts. Therefore, the structure is complicated, the inconvenience of use, and the cost increase. There was a problem that invited.
