  Hereinafter, an example of an embodiment of the present invention will be described with reference to the accompanying drawings.

  FIG. 1 shows the raw seaweed mixture after the treatment of separating foreign matter that cannot pass through the clearance by suctioning the raw seaweed mixture liquid contained in the foreign matter separation tank into the suction chamber through a minute clearance. A schematic configuration of a conventional raw seaweed foreign matter separation device employing a transfer mechanism in the seaweed foreign matter separation device of the present invention for transferring a liquid from the suction chamber to the next step by a combination of a suction pump and a plurality of transfer tubes will be described. Things.

  As shown in FIG. 2, four circular holes 4 (FIG. 1) are formed in the bottom surface 10 a of the foreign matter separation tank 2, the periphery of which is partitioned by the partition walls 8, and the rotation is driven by a motor 49. Rotating plates 5 a, 5 b, 5 c, and 5 d (generically referred to as “rotating plates 5”) that are rotated by the shaft 6 are rotatably fitted inside the circular holes 4 so as to be freely rotatable. The rotating plate 5 is attached to the upper end side of the rotating shaft 6 rotated by the motor 49.

  An annular clearance 3 (FIG. 1) is formed between the inner peripheral wall of the circular hole 4 and the outer peripheral wall of the rotating plate 5 facing the circular hole 4 in plan view. The clearance 3 formed between the inner peripheral wall of the circular hole 4 and the outer peripheral wall of the rotating plate 5 facing the circular hole 4 has a size (size) and interval of about 0.1 mm to 0.2 mm.

  Suction chambers 7a, 7b, 7c, 7d (generally referred to as "suction chamber 7") are provided below the four circular holes, respectively. The structure is such that four drawing chambers 7a, 7b, 7c, 7d are connected to the foreign matter separation tank 2.

  A suction pump 50 is connected to the suction chambers 7a, 7b, 7c, 7d via first transfer pipes 51a, 51b, 51c, 51d, 51e, respectively. As the suction pump 50, for example, a monoflex pump can be used.

  The mixed liquid of the raw seaweed (the original seaweed of nori) and the water (seawater), which has been supplied as indicated by an arrow 33 (FIG. 1) from the pretreatment step, flows through a supply pipe 42 by a pump 41 as indicated by an arrow 34. Is sent to the mince machine 43. The mincing machine 43 is provided with a rotary cutting blade that is orthogonal to the flow of the mixed liquid of the raw seaweed (the original seaweed of seaweed) and water (seawater) moving in the feeding pipe 42. The raw seaweed (the original seaweed of seaweed) is finely cut by passing through. For example, raw nori (a natural algae of nori) having a length of about 50 mm to 300 mm is cut into a length of about 20 mm to 50 mm.

  The raw seaweed mixture liquid, which is a mixture of the raw seaweed (the original seaweed of seaweed) and water (seawater), which has been finely cut in this manner, is continuously transported through the supply pipe 44 as indicated by an arrow 35, and is moved into the foreign matter separation tank 2. As indicated by an arrow 36.

  When the motor 49 is driven to rotate the rotating shaft 6 at an appropriate rotation speed, for example, 200 rpm to 600 rpm, the rotating plate 5 rotates the rotating plate 5 with arrows 30a, 30b, 30c, and 30d (collectively referred to as “arrow 30”). ) And a rotational force is applied to the raw seaweed mixture in the foreign matter separation tank 2. In this way, the raw seaweed mixed solution contained in the foreign matter separation tank 2 rotates in the foreign matter separation tank 2 according to the rotation of the rotating plate 5.

  At the same time, when the suction pump 50 is operated to start suction, the raw seaweed mixture liquid rotating in the direction of the arrow 30 by rotating the rotary plate 5 enters the suction chamber 7 via the clearance 3. It is forcibly sucked.

  In this way, the raw seaweed mixture liquid that has been put into the foreign matter separation tank 2 and rotated by the rotation of the rotating plate 5 is forcibly sucked into the suction chamber 7 through the minute clearance 3 (FIG. 1). Separation of foreign matter that cannot pass through the clearance 3 (for example, litter such as straw chips, ash, shrimp insects, synthetic resin fragments, fragments of crustaceans, seaweeds other than laver, etc.) from the raw seaweed mixture passing through the clearance 3 ·Remove.

  As the raw seaweed mixture liquid is forcibly passed through the clearance 3 while receiving the rotational force in this way, foreign matter that cannot pass through the clearance 3 is separated and removed from the raw seaweed mixture liquid passing through the clearance 3, and the foreign matter separation It remains in the tank 2.

  The raw seaweed mixture liquid subjected to the foreign matter separation treatment, which has been forcibly sucked into the suction chamber 7 through the clearance 3, is first transported by the raw seaweed foreign matter separation device 1 shown in FIGS. 1 and 2. It is sucked through the pipes 51a, 51b, 51c, 51d, 51e as shown by the arrow 37e, and is transferred to the next step through the suction pump 50 and the first transfer pipe 38 as shown by the arrow 61.

  In the next step, for example, it is charged into the storage tank, is stored in the storage tank while being slowly rotated by the rotation of the stirring blades in the storage tank, and is then transferred to the next step by suction or the like. .

  The raw seaweed mixed liquid stored in the foreign matter separation tank 2 is sucked into the suction chamber 7 through the minute clearance 3 to separate the raw seaweed mixed liquid that cannot pass through the clearance 3, and the raw seaweed mixed liquid is subjected to the treatment. As a transfer mechanism for transferring from the suction chamber 7 to the next process by a combination of a suction pump 50 such as a monoflex pump and a plurality of transfer pipes, the structure of the transfer mechanism employed in the conventional foreign matter separation device 1 is, for example, shown in FIG. The configuration shown in FIG.

  In FIG. 3, four suction chambers 7a, 7b, 7c, 7d whose upper ends are respectively connected to the foreign matter separation tank 2 are respectively connected to the first transfer pipes 38a, 38b, via suction pumps 50a, 50b, 50c, 50d. The upstream sides of 38c and 38d are connected.

  The first transfer pipe 38a and the first transfer pipe 38b are connected to the upstream side of the large-diameter second transfer pipe 53a via the repeater 52a on the respective downstream sides, and the first transfer pipe 38c and the first transfer pipe 38d are connected. Are connected to the upstream side of the large-diameter second transfer pipe 53b via a relay 52b on each downstream side.

  The raw seaweed mixed liquid sucked from the suction chamber 7a by the suction pump 50a and the raw seaweed mixed liquid sucked from the suction chamber 7b by the suction pump 50b are connected to the repeater 52a downstream of the first transfer pipes 38a, 38b. They merge and are transferred to the next step via the second transfer pipe 53a as shown by an arrow 61.

  The raw seaweed mixed liquid sucked from the suction chamber 7c by the suction pump 50c and the raw seaweed mixed liquid sucked from the suction chamber 7d by the suction pump 50d are connected to the repeater 52b downstream of the first transfer pipes 38c and 38d. They merge and are transferred to the next step as shown by the arrow 61 via the second transfer pipe 53b.

  The inner diameters of the first transfer pipes 38a, 38b, 38c, 38d are the same. The inner diameters of the second transfer pipes 53a and 53b are the same. The inner diameter of the second transfer pipes 53a, 53b is larger than the inner diameter of the first transfer pipes 38a, 38b, 38c, 38d.

The raw seaweed mixture liquid flowing through the first transfer pipes 38a and 38b joins at the repeater 52a and flows into the large-diameter second transfer pipe 53a. Similarly, the raw seaweed mixture liquid flowing through the first transfer pipes 38c and 38d joins at the repeater 52b and flows into the large-diameter second transfer pipe 53b. At this time, the suction chambers 7a, 7b and 7c , 7d, the state of the raw laver mixture, the state of being sucked, and the like may be different from each other. This is probably due to the influence of the respective states of the raw seaweed mixed liquid present in the foreign matter separation tank 2 above the suction chambers 7a, 7b, 7c, 7d via the rotary plate 5.

  For this reason, the inner diameters and storage volumes of the suction chambers 7a to 7d, the sizes of the rotating plates 5a to 5d loosely fitted to the upper end openings of the suction chambers 7a to 7d, the rotation speeds of the rotating plates 5a to 5d, and the rotating plates 5a to 5d Of the clearance formed between the outer peripheral surface of the suction chamber and the inner peripheral surface of the upper end opening of the suction chambers 7a to 7d, the suction capacity of the suction pumps 50a to 50d, the diameter and the length of the first transfer pipes 38a to 38d, etc. Even if the various conditions relating to the transfer of the raw laver mixture through the first transfer pipes 38a to 38d are made the same, and the suction pumps 50a to 50d are operated so as to operate with the same suction force, The flow rate and flow rate of the raw laver mixture flowing into the repeater 52a through one transfer pipe 38a, and the flow rate and flow velocity of the raw laver mixture flowing into the repeater 52a through the first transfer pipe 38b Can be different.

  For example, the flow rate and the flow velocity of the raw nori mixed liquid flowing into the repeater 52a via the first transfer pipe 38a are better than the raw laver mixed liquid flowing into the repeater 52a via the first transfer pipe 38b. It is possible that the flow rate and the flow velocity of the air flow may become larger than the flow speed.

  When such a state occurs, the flow rate and the flow rate of the raw nori mixed liquid to the repeater 52a via the first transfer pipe 38a are better than the raw nori mixed liquid to the repeater 52a via the first transfer pipe 38b. Therefore, the transfer of the raw seaweed mixture from the suction chamber 7b to the repeater 52a via the first transfer pipe 38b is not performed smoothly. Occasionally, a backflow to the suction chamber 7b occurs via the first transfer pipe 38b, and the suction of the raw nori mixed liquid into the suction chamber 7b becomes weaker than the suction of the raw nori mixed liquid into the suction chamber 7a. Can happen.

  The occurrence of such imbalance is not desirable for the foreign matter separation processing by the raw seaweed foreign matter separation apparatus 1.

  The raw seaweed mixed liquid stored in the foreign matter separation tank 2 is sucked into the suction chamber 7 through the minute clearance 3 to separate the raw seaweed mixed liquid that cannot pass through the clearance 3, and the raw seaweed mixed liquid is subjected to the treatment. FIG. 4 shows an example of a transfer mechanism for transferring from the suction chamber 7 to the next process by a combination of a suction pump 50 such as a monoflex pump and a plurality of transfer pipes, which is employed in the raw seaweed foreign matter separating apparatus of the present invention. .

  Portions common to the conventional transfer mechanism employed in the conventional raw laver foreign matter separating apparatus shown in FIG. 3 are denoted by the same reference numerals, and description thereof is omitted.

  Also, the raw seaweed mixture after the process of separating the foreign matter that cannot pass through the clearance 3 by applying the raw seaweed mixture liquid contained in the foreign matter separation tank 2 to the suction chamber 7 through the minute clearance 3 is performed. A transfer mechanism for transferring the liquid from the suction chamber 7 to the next step by a combination of a suction pump 50 such as a monoflex pump and a plurality of transfer pipes, except that the structure described in FIG. 4 is employed. The structure and configuration of the foreign matter separating device are the same as the structure and configuration of the conventional foreign matter separating device described with reference to FIGS.

  As in the embodiment described with reference to FIG. 3, the four suction chambers 7a, 7b, 7c and 7d whose upper ends are connected to the foreign matter separation tank 2 in FIG. 4 are respectively connected via suction pumps 50a, 50b, 50c and 50d. Thus, the upstream side of the first transfer pipes 38a, 38b, 38c, 38d is connected.

  The first transfer pipe 38a and the first transfer pipe 38b are respectively connected to the upstream side of the large-diameter second transfer pipe 53a via a relay 62a on the downstream side, and the first transfer pipe 38c and the first transfer pipe 38d are connected. Are connected to the upstream side of the large-diameter second transfer pipe 53b via the relay 62b on each downstream side.

  A repeater 62a provided at a position downstream of the first transfer pipes 38a and 38b and an upstream side of the second transfer pipe 53a is provided with a raw seaweed mixture liquid flowing through the first transfer pipes 38a and 38b. Is provided with an accommodating space portion 62c that temporarily stays before flowing into the second transfer pipe 53a.

  Thereby, the flow rate and the flow rate of the raw nori mixed liquid flowing into the repeater 62a through the first transfer pipe 38a and the flow rate of the raw nori mixed liquid flowing into the repeater 62a through the first transfer pipe 38b are determined. Even when the flow rate and the flow rate are different, the raw seaweed mixture flowing through the first transfer pipes 38a and 38b is provided inside the repeater 62a before flowing into the second transfer pipe 53a. In the accommodation space 62c.

  Therefore, between the flow rate and flow rate of the raw nori mixed solution to the repeater 62a via the first transfer pipe 38a, and the flow rate and flow rate of the raw nori mixed solution to the repeater 62a via the first transfer pipe 38b. Even if a state in which one is superior to the other has occurred, the flow rate, the flow rate in the first transfer pipe on the side where the flow rate is inferior, the flow rate is the flow rate in the other first transfer pipe, An imbalance between the flow rate and the flow rate causes the flow rate to decrease further, and as a result, a reverse flow occurs toward the suction chamber to which the first transfer pipe on the side where the flow rate and the flow rate are inferior is connected. The disadvantage that the suction efficiency in the suction chamber to which the first transfer pipe on the inferior side is connected is reduced does not occur.

  The repeater 62b disposed at the downstream side of the first transfer pipes 38c and 38d and the upstream side of the second transfer pipe 53b on the right side of FIG. 4 also flows inside the first transfer pipes 38c and 38d. The storage space part 62d in which the raw seaweed mixture liquid temporarily stays before flowing into the second transfer pipe 53b is provided.

  Thereby, the same operation and effect as described above can be exerted.

  Thus, according to the present embodiment, a process of separating foreign matter that cannot pass through the clearance 3 by sucking the raw seaweed mixed solution stored in the foreign matter separation tank 2 into the suction chamber 7 through the minute clearance 3 is performed. A transfer mechanism for transferring the raw seaweed mixed solution after the application from the suction chamber 7 to the next process by a combination of the suction pump 50 and the plurality of transfer pipes (the first transfer pipes 38a and 38b and the second transfer pipe 53a). In the provided raw seaweed foreign matter separation device, the raw seaweed mixed liquid subjected to the foreign matter separation treatment can be smoothly transferred from the suction chamber 7 to the next step.

  In the case of a conventional foreign matter separation device employing the conventional transfer mechanism described in FIG. 3, a plurality of suction chambers 7a, 7b, 7c, 7d connected to the foreign matter separation tank 2 of the raw seaweed foreign matter separation device 1 are provided. When the first transfer pipes connected to each other via the suction pump 50 merge on the downstream side with the upstream side of one second transfer pipe, the raw material transferred by each of the plurality of first transfer pipes. In some cases, the flow rate and flow velocity of the laver mixture were unbalanced.

  This is based on various conditions relating to the transfer of the raw seaweed mixture, such as the size of the suction chamber 7, the size of the rotating plate 5, the size of the clearance, the suction capacity of the suction pump, the size of the first transfer pipe and the second transfer pipe. Even if they were the same, they would occur. The state of the raw seaweed mixture liquid present in the foreign matter separation tank 2 above the suction chambers 7a, 7b, 7c, and 7d via the rotating plate 5 (for example, finely cut raw seaweed (raw seaweed of seaweed)) Are different in size, the concentration of finely cut raw laver (the original algae of laver) in the raw laver mixture is different, and the flow state of the raw laver mixture on the upper side of each rotating plate 5 is also different. It is thought that it is affected by circumstances such as various wards.

  When such imbalance and imbalance exist, the flow rate of the raw laver mixture to the confluence in the first transfer pipe where the flow rate and flow velocity are inferior, and the flow rate and flow rate in the first transfer pipe where the flow rate and flow rate are superior The flow of the raw seaweed mixed liquid does not smoothly proceed as compared with the flow of the raw seaweed mixed liquid in the confluence part, and sometimes a backflow to the suction chamber occurs via the first transfer pipe or the raw seaweed mixed liquid into the suction chamber May be weaker than the suction of the raw laver mixture into another suction chamber to which the first transfer pipe having the higher flow rate and flow velocity is connected.

  According to the foreign matter separation apparatus of the present invention in which the transfer mechanism shown in FIG. 4 is employed, the raw seaweed mixed liquid is passed from the foreign matter separation tank to each of the plurality of suction chambers connected to the foreign matter separation tank via the clearance. When forcible suction is performed to perform foreign matter separation processing, it is possible to prevent imbalance in the flow and transfer of the raw seaweed mixture liquid from each suction chamber to the next process after the foreign matter separation processing, and good. Thus, efficient foreign matter separation processing can be performed.

  FIG. 5 shows a state in which the downstream sides of the first transfer pipes 67a, 67b, 67c, and 67d whose upper ends are connected to a suction chamber (not shown) via a suction pump (not shown) are respectively connected via cubic repeaters 66a. , And are joined to the upstream side of the second transfer pipe 69.

  Each of the first transfer pipes 67a, 67b, 67c, 67d has an inner diameter of 50 mm, the second transfer pipe 69 has an inner diameter of 65 mm, and flows through the first transfer pipes 67a, 67b, 67c, 67d provided inside the repeater 66a. The size of the accommodation space in which the mixed fresh laver mixture temporarily stays before flowing into the second transfer pipe 69 can be a cube of 75 mm × 75 mm × 75 mm.

  The raw seaweed mixed liquid flowing from the suction chamber (not shown) through the first transfer pipes 67a, 67b, 67c, 67d via the suction pump (not shown) as indicated by arrows 68a, 68b, 68c, 68d. Even if there is a difference in the flow rate and the flow rate, a temporary residence is performed in the accommodation space inside the repeater 66a before the raw laver mixture flows from the repeater 66a into the second transfer pipe 69. Therefore, the flow rate and the flow velocity are balanced, and the flow of the raw seaweed mixture from the second transfer pipe 69 indicated by the arrow 70 becomes smooth. Further, a backflow may occur toward each suction chamber (not shown) to which the upstream side of the first transfer pipes 67a, 67b, 67c, 67d is connected, or the upstream side of the first transfer pipes 67a, 67b, 67c, 67d may be connected. It is possible to prevent the imbalance in the suction state in each suction chamber (not shown).

  FIG. 6 shows that the first transfer pipes 71a, 71b, 71c, 71d, each of which is connected on the upstream side to a suction chamber (not shown) via a suction pump (not shown), have a rectangular parallelepiped relay 66b. It joins the upstream side of the two transfer pipes 73.

  Each of the first transfer pipes 71a, 71b, 71c, and 71d has an inner diameter of 50 mm, the second transfer pipe 73 has an inner diameter of 65 mm, and flows through the first transfer pipes 71a, 71b, 71c, and 71d provided inside the repeater 66b. The size of the accommodation space in which the mixed fresh seaweed mixture temporarily stays before flowing into the second transfer pipe 73 can be a rectangular parallelepiped of 50 mm × 50 mm × 350 mm.

  The raw seaweed mixture flowing from the suction chamber (not shown) through the first transfer pipes 71a, 71b, 71c, 71d via the suction pump (not shown) as indicated by arrows 72a, 72b, 72c, 72d. Even if there is a difference in the flow rate and the flow velocity, before the raw seaweed mixture liquid flows into the second transfer pipe 73 from the repeater 66b, the temporary storage is performed in the accommodation space inside the repeater 66b. , The flow rate and the flow velocity are balanced, and the flow of the raw seaweed mixture from the second transfer pipe 73 indicated by the arrow 74 becomes smooth. Also, a backflow may occur toward each suction chamber (not shown) to which the upstream side of the first transfer pipes 67a, 67b, 67c, 67d is connected, or the upstream side of the first transfer pipes 71a, 71b, 71c, 71d may be connected. It is possible to prevent the imbalance in the suction state in each suction chamber (not shown).

  Thereby, when the foreign matter separation process is performed by forcibly sucking the raw seaweed mixed solution from the foreign matter separation tank 2 to each of the plurality of suction chambers 7a, 7b, 7c, 7d via the clearance 3, the foreign matter separation process is performed. After the application of the raw seaweed mixed solution from each of the suction chambers 7a to 7d to the next step, imbalance occurs in the flow and transfer of the raw seaweed mixed liquid, backflow occurs toward each of the suction chambers 7a to 7d, and each of the suction chambers 7a to 7d. It is possible to prevent imbalance in the suction to the 7d, and to perform a good and efficient foreign matter separation process.

  As described above, the preferred embodiments of the present invention have been described with reference to the accompanying drawings. However, the present invention is not limited to such embodiments, and various modifications may be made without departing from the scope of the claims. It can be changed to a form.

  For example, in the above description, an example was described in which four suction chambers were connected to the foreign matter separation tank. However, two suction chambers or six or eight suction chambers were connected to the foreign matter separation tank. It is the same even when there is.

  A first transfer pipe is connected to each of the plurality of suction chambers connected to the foreign matter separation tank via a suction pump, and a downstream side of the plurality of first transfer pipes and a downstream side of the plurality of first transfer pipes. A repeater disposed between the first transfer pipe and a second transfer pipe whose side merges with the upstream side thereof contains therein the raw seaweed mixed solution flowing through the plurality of first transfer pipes. By having a configuration having a storage space portion that temporarily stays before flowing into the pipe, the flow rate of the raw seaweed mixed liquid flowing through each of the plurality of first transfer pipes, balance the state of the flow velocity, The flow rate, the flow of the raw laver mixture in the first transfer pipe where the flow velocity is inferior to the confluence portion of the raw seaweed mixture is not performed smoothly, or sometimes a backflow to the suction chamber occurs through the first transfer pipe, The suction of the raw seaweed mixture into the suction chamber, the flow rate, the flow rate The first transfer pipe that Tsu can be prevented that is generated becomes weaker than the suction of raw laver mixture to another suction chamber are connected.
