Description

  The present invention takes large jellyfish, small fish, and floating substances on the sea captured on the fishnet back to land, and uses only large jellyfish mixed with small fish and floating substances on the sea. The present invention relates to a large jellyfish separation apparatus that processes large jellyfish after separating suspended matter and large jellyfish and a large jellyfish processing apparatus including the large jellyfish separation apparatus.

  Conventionally, large jellyfishes such as Echizen jellyfish and bizen jellyfish have been proposed to break down fish nets and block seawater intakes of power plants, and methods for treating them.

  In the prior art, after capturing a large jellyfish, it was common to crush the large jellyfish to an extent that does not adversely affect fisheries and power generation, and then discard the crushed large jellyfish in the sea.

  This large jellyfish treatment method is carried out on a large scale using a large treatment device at a power plant, and since a fisherman also carries these treatment devices on a fishing boat, etc., it is carried out at sea. It was difficult to do without a fisherman. And the technique like patent document 1 was disclosed as what is performed on the sea.

  For small fishermen, it is difficult to equip small fishing boats with facilities for processing jellyfish even if they capture large jellyfish with a fishnet, so they have to be disposed of in the sea as they are. And so-called ocean dumping that discards the captured large jellyfish into the sea pollutes the fishing grounds, and a method of treating it after taking it back to the port has been studied.

  Large jellyfish may be used for food, but the demand is limited, and Echizen jellyfish in large jellyfish is not generally used for food. In recent years, a large amount of Echizen jellyfish has occurred in the waters near Japan, and they have inhabited many fishing grounds near Japan, resulting in damage regardless of the size of the fishermen. Moreover, 90% or more of the large jellyfish is water, and it has been considered to use components other than water. And since the solid component which is a component remove | excluding the water | moisture content of a large jellyfish contains nitrogen (N), potassium (K), and magnesium (Mg), as a method of utilizing this, the method of utilizing for the raw material of a fertilizer Was considered.

  However, fishermen capture large jellyfish with fishnets when fishnets are used for the purpose of catching marketable fish, and large jellyfish are captured together with fish with marketability. In some cases, small fish other than large jellyfish and marine suspended matter are mixed in the fish net even after removing the fish (hereinafter, a mixture of small fish and marine suspended matter is abbreviated as “small fish”). It was general. When fish other than marketable fish are removed from the fish net and transferred to a fish transport container such as a toro box (hereinafter abbreviated as “toro box”), large jellyfish, small fish, etc. are mixed. It was common to be a thing. If the large jellyfish mixed with small fish is buried in the soil or incinerated, it is not necessary to sort out the small fish and large jellyfish, but only the large jellyfish is used as fertilizer. In this case, it was necessary to remove these small fish because the components of the fertilizer became constant and the quality of the fertilizer could not be maintained.

(Operation of large jellyfish processing equipment)
When a fisherman performs fishing with a fish net from a fishing boat, large jellyfish, small fish, etc. are captured by the fish net together with marketable fish. Fish having marketability is sorted on a fishing boat and collected in a trolley box or the like. The remaining large jellyfish, small fish, etc. are put in another toro box or the like, and are accumulated near the place where the large jellyfish processing apparatus 1 is installed.

  The large jellyfish processing apparatus 1 is activated in a state where large jellyfish mixed with an appropriate amount of small fish and the like are gathered. When the large jellyfish processing apparatus 1 is started, the water discharge port 13 and the solid content discharge port 14 are closed by a closing means such as a valve. The operation that is the start of the large jellyfish processing apparatus 1 is started by connecting the electric motor 42 to a predetermined power source and supplying electric power. When the large jellyfish processing apparatus 1 starts operation, the separation plate 21 of the separation unit 6 and the two cruciform blades 30 of the stirring unit 7 rotate at a predetermined rotational speed.

  A large jellyfish consists of an umbrella-shaped main body part and a large number of tentacle parts, and the umbrella-shaped main body part occupies most of the mass and volume. Most of the umbrella-shaped main body portion is made of gelatinous material and maintains an umbrella-like shape even in the air, but since it is gelatinous material, it becomes softer than components forming small fish or the like.

  FIG. 5 is a diagram showing a state in which a large jellyfish 51, a small fish, etc. 52 are put on the separation plate 21. FIG. In a state where the large jellyfish processing apparatus 1 starts operation and the separation plate 21 is rotating, the operator lifts the trolley box etc. by manual means or mechanical means such as a lift or winch, and turns the trolley box etc. A mixture of the large jellyfish 51 and the small fish 52 is charged from the charging port 11.

  The large jellyfish 51 is gelatinous, and at the same time when the large jellyfish 51 gets on the separation plate 21, the large jellyfish 51 is cut and raised by the inertia force acting opposite to the rotation direction by the self-weight of the large jellyfish 51. 51 will be pierced.

  On the other hand, the components forming the small fish 52 are harder than the large jellyfish 51, lighter than the large jellyfish 51, and the triangular tips of the cut and raised portions 23a, 23b, 23c, and 23d. The angle of the surface is 64 degrees or more, the tip is thick and the blade-like processing is not performed, and the cut and raised portions 23a, 23b, 23c, and 23d are on the surface of the small fish 52 for reasons such as not being sharp. The cut and raised parts 23a, 23b, 23c, and 23d are difficult to pierce the small fish 52 or the like. Further, even if pierced, the main component of the small fish etc. 52 is hard so that the small fish etc. 52 is not crushed. If the small fish etc. 52 is cut and raised and does not stab into 23a, 23b, 23c, 23d, the separating plate 21 rotates, so that centrifugal force acts on the small fish etc. 52, and the outer periphery of the separating plate 21 In the vicinity of the separation cover 22 where there is no wake 23a, the small fish 52 and the like gather together in a state where the original shape is almost maintained.

  The large jellyfish 51 in the state of being stabbed into the cut-and-raised portions 23a, 23b, 23c, and 23d comes to pierce deeper into the cut-and-raised portions 23a, 23b, 23c, and 23d as the separation plate 21 rotates. This state will be described with reference to FIG. 6 which is a cross-sectional view taken along line AA ′ in FIG.

  In FIG. 6, since the large jellyfish 51 has a considerable weight as described above, an inertial force is generated in the large jellyfish 51 when the separating plate 21 rotates, and the large jellyfish 51 is further cut and raised in the gelatinous material 23a. It will pierce deeply. If the cut and raised portion 23a is further pierced by the large jellyfish 51, the angle of the tip of the cut and raised portion 23a is about 67 degrees, so that the large jellyfish 51 is largely cut. Part of the large jellyfish 51 that has been cut flows due to the inertial force of the soft gelatinous material inside, so that a part of the gelatinous material of the large jellyfish 51 is cut and raised to the lower side of the cutout 23a. Towards the hole 24a on the lower side. As the separating plate 21 continues to rotate, the gelatinous substance of the large jellyfish 51 continuously moves toward the hole 24a and from the hole 24a toward the lower side of the separating plate 21. A part of the large jellyfish 51 that hangs down on the lower side of the separation plate 21 is further pushed out by the inertial force when the separation plate 21 rotates, and falls into the lower stirring portion 7 through the triangular hole 24a. By continuing this, most of the large jellyfish 51 falls to the lower stirring portion 7.

  The large jellyfish 51 that has fallen on the stirring unit 7 accumulates in the processing container 12 of the stirring unit 7, and is further crushed and stirred by the rotating double cruciform blade 30 and the container blade 33 on the inner surface of the processing container 12 of the stirring unit 7. Finally, it is divided into large jellyfish moisture and large jellyfish solids.

  Then, the operation of the large jellyfish processing apparatus 1 is stopped at an appropriate place, and small fish and the like are taken out from the insertion port 11 shown in FIG. 1 or FIG. 2 and discarded by a process such as incineration or embedding. The water of the large jellyfish is taken out by opening the water outlet 13 and treated as sewage. The solid content of the large jellyfish is taken out by opening the solid content outlet 14, and is collected and used as a raw material for fertilizer.

  The triangular shape and arrangement of the cut-and-raised portions 23a, 23b, 23c, and 23d shown above are examples, and need to be changed according to the diameter of the separation plate 21 that changes with the diameter of the processing vessel 12. In addition, the size is appropriately changed according to the size of the large jellyfish that needs to be processed, the type of small fish, and the like. In addition, about the triangle of cut-and-raised 23a, 23b, 23c, and 23d, if it is a shape which pierces a large jellyfish and does not pierce a small fish etc., it is not necessary to stick to a triangle, and it can select and implement freely. The holes 24a, 24b, 24c, and 24d are also described as triangles for convenience of processing, but the large jellyfish that has been cut to the extent that the gelatinous material of the large jellyfish that has been cut can pass through. If it is a position which is easy to pass through the separating plate 21, the size, shape and position of the hole can be freely selected and implemented.

(Other implementation methods)
In Example 1, although the large jellyfish processing apparatus 1 showed the example by which the separation part 6 which is a large jellyfish separation apparatus, and the stirring part 7 which is a large jellyfish stirring apparatus were comprised integrally, the separation part 6 is shown. An independent large jellyfish separator can also be used. In this case, the large jellyfish separated by the separation plate 21 is collected in a trolley box or the like, and this is put into a large jellyfish agitation device that is only the agitation unit 7.
