(Operation) With reference to FIGS. 7 to 11, the operation of the raw seaweed foreign matter removing apparatus including the foreign matter separating apparatus D2 according to the present invention will be described. Reservoir T of the raw seaweed foreign matter removal device
Nori mixed liquid is introduced into 3 from supply pipe p1, and separation drum 1a is immersed in the nori mixed liquid. When the laver mixture in the storage tank T3 passes through the separation drum 1a, foreign substances such as dust are separated by the suction action of a suction pump (not shown) and sent to the next step.

The separation of foreign matter from the laver mixture by the separation drum 1a of the foreign matter separation device D2 is performed as follows. The width of the slit 100 of the separation drum 1a is adjusted by turning the gap adjusting plate 67 so as to allow the nori original algae to pass therethrough and to prevent foreign matter such as dust from passing therethrough. Further, the separation drum 1a is rotated at a low speed in the axial direction (clockwise in FIGS. 8 and 9) by the low-speed motor M.

The operation of the suction pump (not shown) constituting the primary suction means causes the storage section t0 in the storage tank T3 to operate.
Nori mixed liquid stored in the separation drum 1a constituting the primary suction means from the slit 100 of the slit 100 of the separation drum 1a rotating and moving in the storage part t0.
Enter the distribution section F3. At this time, foreign matter such as dust is caught and separated by each slit 100, and at the same time, a part of the raw laver is also caught together. The laver mixture from which the foreign matter has been separated passes through the distribution port F3, passes through the distribution port 25, enters the distribution section F4 inside the fixed shaft pipe 2a, passes through the water pipe p2, and is sent to the discharge side.

On the other hand, the cleaning liquid (fresh water or seawater) is supplied from the distribution part f4 to the distribution part f5 by the operation of the feed pump (not shown) constituting the primary cleaning means.

The foreign matter such as dust caught on the outside of the slit 100 by the above-described process enters the storage tank T4 through the external seal member 8d while being attracted to the slit 100 with the rotation of the separation drum 1a. At this time, a part of the foreign matter is rubbed by the sliding contact plate 81 of the external seal member 8d and falls off, but the rest is caused by a slight step difference between the edges of the fixed outer peripheral member 12 and the movable outer peripheral member 13 constituting the slit 100. As a result, the liquid enters the storage tank T4 as it is.

In the storage tank T4, the roller 61 of the control arm 60 of the movable outer peripheral member 13 located between the outer seal members 8c and 8d is guided by the guide piece 68 with the rotation of the separation drum 1a, and the movable outer peripheral member 13 rotates in the direction in which the slit 100 further expands (FIG. 11).
reference). As a result, the cleaning liquid blows out from the circulation part f5 into the storage tank T4 through the expanded slit 100, and the foreign matter caught on the slit 100 is separated from the raw seaweed (see FIG. 8). When the roller 61 of the control arm 60 comes off the guide piece 68, the movable outer peripheral member 13 returns to its original position, and the width of the slit 100 returns to its original width at which the foreign matter can be separated.

The washing liquid containing foreign matter and raw laver is stored in the storage tank T4, and when the liquid level sensor S4 detects the upper limit liquid level, a suction pump (not shown) constituting the secondary suction means
Operates. As a result, the cleaning liquid containing the foreign matter and the raw laver enters the circulation part F5 in the separation drum 1a constituting the secondary suction means from the slit 100 moving between the external seal members 8b and 8c in the storage tank T4. . At this time, foreign substances such as dust are caught and separated by the slits 100, and most of the raw seaweed contained in the washing liquid enters the circulation part F5 because of its low concentration. The foreign matter is separated, and the washing liquid containing the raw seaweed passes through the flow port 25a from the flow section F5, enters the flow section F6 inside the fixed shaft tube 2a, and is sent to the discharge side.

On the other hand, the cleaning liquid (fresh water or seawater) is supplied from the distribution part f6 to the distribution part f7 by the operation of the feed pump (not shown) constituting the secondary cleaning means. In the storage tank T4, the roller 61 of the control arm 60 of the movable outer peripheral member 13 moving between the outer seal members 8a and 8b is guided by the guide piece 69 with the rotation of the separation drum 1a, and the movable outer peripheral member 13 is slit. 100 rotates in the direction to further expand. As a result, the cleaning liquid is blown out from the circulation part f7 to the circulation part f8 through the expanded slit 100, and the foreign matter caught on the slit 100 is separated. Then, the secondary cleaning liquid containing the foreign matter is discharged into the discharge pipe t9.
Through the separation tank 5 to the outside. When the roller 61 of the control arm 60 comes off the guide piece 69,
The movable outer peripheral member 13 returns to the original position, and the width of the slit 100 also returns to the original width at which the foreign matter can be separated.
Move into zero. The secondary suction pump and the secondary feed pump stop when the liquid level sensor S4 detects the lower limit liquid level of the storage tank T4, and the secondary suction pump and the secondary feed pump have the upper and lower liquid levels. It operates when it is within the range.

As described above, the foreign matter separation device D2 separates foreign matter contained in the nori mixture twice, once and once, so that most of the raw nori contained in the nori mixture is sent to the discharge side. And the recovery rate of laver can be improved. Note that the foreign matter separation device D2 has a structure in which secondary separation and cleaning are repeated, but a structure in which more partitions are provided in the circumferential direction of the separation drum to perform tertiary separation, cleaning, or more processing. You can also.
In the above embodiment, the foreign matter separating devices D1, D
2 is a horizontal type, but may be a vertical type. Furthermore,
In the storage tanks T2 and T3, a plurality of foreign matter separation devices D are respectively provided.
1, D2 can also be arranged.
