[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mixture of raw seaweed and seawater (a mixture of raw seaweed and seawater; hereinafter referred to as a raw seaweed mixture) from foreign matter (dust, shrimp, mussels, ami). The present invention relates to a foreign matter separation mechanism of a raw seaweed foreign matter separation / removal device that separates and removes lint and other contaminants).

[0002]

2. Description of the Related Art Conventionally, a raw seaweed foreign matter separation / removal device (hereinafter,
The foreign matter separation / removal device) uses the clearance of the foreign matter separation mechanism consisting of the rotating plate and bottom (annular frame plate) of the raw seaweed mixed liquid tank, and the punching metal type filtration of the raw seaweed mixed liquid tank. The structure is roughly divided into a structure using a filter member such as a cylinder and a coil type filter cylinder. The present invention is a configuration that uses the clearance of the former foreign matter separating mechanism (hereinafter referred to as a foreign matter separating mechanism). As a foreign matter separating / removing device equipped with this foreign matter separating mechanism, there is a foreign matter separating / removing device for raw laver disclosed in Japanese Patent Laid-Open No. 8-140637 (reference). Its composition is
A rotary plate is fitted into the inner peripheral edge of the annular frame plate portion of the tubular mixed liquid tank in a substantially flush state with a slight clearance, and the rotary plate can be rotated about its axis by an appropriate drive means. There is a foreign matter discharge port. It is disclosed that the present invention is characterized in that foreign matter can be efficiently separated and removed by utilizing the difference in specific gravity and centrifugal force, that clogging is difficult, and that it is not necessary to provide another clogging cleaning device. .

[0003]

SUMMARY OF THE INVENTION In the above-mentioned document invention, foreign matter can be efficiently separated and removed by utilizing the clearance of the internal fitting structure, the difference in specific gravity and centrifugal force, and the clogging is small because the rotary plate constantly rotates. And so on. However, in order for the raw seaweed flowing in a substantially horizontal direction (in a substantially horizontal developed state) due to centrifugal force in the tubular mixed solution tank to pass through the clearance of the vertical structure due to the internal fitting of the tubular mixed solution tank, , It is necessary to turn the raw seaweed vertically. In this way, in order to change the direction of the raw seaweed from the substantially horizontal direction to the vertical direction, it is necessary to give the raw seaweed a considerable amount of force,
There is a problem that raw seaweed may be damaged or that the vertical structure is not sufficiently guided to the clearance. In this invention, the raw seaweed and seawater in the mixed liquid tank are separated and then flow downward in the clearance by the natural drop method. That is, the pump is not used to forcibly suck. Therefore, in order to guide the raw seaweed and seawater in the mixed liquid tank to the clearance of the vertical structure, and to efficiently separate the foreign matter through the clearance, there are some practical problems.

According to the invention of claim 1, the raw seaweed which is in a substantially horizontal developed state by the rotation of the rotary plate is provided.
It is possible to suck in the almost horizontal state as it is, and to secure the suction force and the amount of the raw seaweed suction, or to suck the raw seaweed from the substantially horizontal direction (depending on the substantially horizontal expansion state) without damaging the raw seaweed. In addition, it is intended to efficiently separate foreign substances. Claim 1 has a foreign matter separating mechanism provided in a raw seaweed mixed solution tank for pooling a raw seaweed / seawater mixed solution having a foreign matter discharge port, and a connection port provided in the bottom of the raw nori mixed solution tank.

Consists of a suction pump provided on a hose connected to the connection port provided on the selection casing, and extends substantially horizontally along the bottom.
The raw seaweed that swirls in the open state is removed from the foreign matter separation mechanism step.
Difference and horizontal lap clearance, and suction pump
The raw seaweed that has been sucked in can be transported to the outside of the raw seaweed foreign matter separation / removal device through the connection port.
The foreign matter separation mechanism of the raw seaweed foreign matter separation and removal device.

The invention of claim 2 intends to easily adjust the clearance of the horizontal stacking type, to adjust the suction force and amount, to facilitate the maintenance management, to improve the effect of preventing clogging, and the like. Claim 2
Is the foreign matter separating mechanism of the raw seaweed foreign matter separating and removing apparatus according to claim 1, wherein an upward and / or downward inclined portion is formed in a part of the clearance.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The raw seaweed mixed solution is sequentially introduced from the raw seaweed tank into the raw seaweed mixed solution tank of the present invention. The introduced mixed liquid is swirled in a substantially horizontal direction by a rotating plate.
While being swirled (in a substantially horizontal unfolded state), it is guided to the horizontally overlapping clearance of the foreign matter separating mechanism by the suction pump. The horizontal overlapping clearance is opened in the same direction as the flow swirl direction. Therefore, the raw seaweed in the fluid that swirls swiftly passes through the clearance of the horizontal stacking type very smoothly without any resistance, reaches the inner bottom surface of the sorting casing, and then enters the processing tank via the connection port. Be guided.

[0007] If the horizontal stacking type clearance is cleaned, the function is maintained or managed, or if the horizontal stacking type clearance is clogged, the backwashing pump is operated and seawater is washed from the backwashing port. A jet is jetted to backwash the horizontal overlap type clearance. At this time, the jet plate raises the rotary plate to expand the horizontal stacking type clearance and remove foreign matter clogged in the horizontal stacking type clearance.
