DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a skin cocoon (thin cocoon).
The on treatment MakotoSo location of Kawasumayu be separated into thin skin and pupa.

[0002]

Of the Prior Art] A conventional skin nest cocoon thin skin fibers, since pupae have a value in use as bait in fish farms, etc., but it is conventional to separate the thin skin and pupae, conventional treatment MakotoSo The installation is
The nest cocoon sent out from the reeling machine is dehydrated by a dehydrator and then washed by a washing machine. Then, in a wet state, the nest cocoon is put on a nest processing device to remove thin skin (fiber),
The skin and the pupa are taken out separately and each is dried with hot air.

[0003]

In this method, since the skin cocoons are treated in a wet state, the working environment is poor due to odor and the like, and a large amount of water is required to wash the skin cocoons. Not only that, when draining the washed water, rivers and the like are polluted with the drainage water, and the BOD and COD of the rivers and the like are increased.
There is a problem that adversely affects the natural environment. An object of the present invention is to provide an apparatus for treating skin cocoons that does not have such a problem.

[0004]

[0005]

According to the first aspect of the present invention, there is provided an incision section for making a cut in a part of a dried nest cocoon supplied from a hopper, and a nest cocoon cut in the incision section. And a cocoon separation part for separating the pupa into thin skins. The incision part is opposed to the rotary blade provided with a number of disc-shaped blades, and the rotary blade has a passing gap for the nest cocoon. The open cocoon separating section is provided with a horizontally elongated box, and an opening for the skin cocoon cut in one side, provided in the box, and an outlet for the thin skin separated on the other side. A cylindrical rotating basket that rotates about a horizontal axis, a spreading claw that opens a cut of the cutaneous cocoon cut in cooperation with a ridge provided on the inner peripheral surface of the rotating basket, Rotor blades that generate wind toward the discharge side of the thin skin provided in the basket,
It is composed of a discharge conveyor pupae provided in the lower part of the rotary cage
With such a configuration, the skin and the pupa can be continuously and easily separated. In addition, since water is not used in this process, the amount of water used can be greatly reduced.

The rotary blade 14 and the rubber roll 15 are
The electric motor 20 is rotated in a direction in which the nest cocoon a bites into the gap between the two, that is, in the direction of the arrow shown in FIG. 1, so that about one to three cuts are made in the nest cocoa a sandwiched between the two. (Depending on the manner of contact of the nest cocoon a with the rotary blade 14). Reference numeral 21 denotes a scraper in which a comb-like portion faces between the disk blades constituting the rotary blade 14, and the scraper 21 rotates about a shaft 21a to rotate between the disk blades configuring the rotary blade 14. The state can be switched between a state in which the comb-tooth-shaped part faces and a state in which the comb-teeth part is separated therefrom. Reference numeral 21b denotes a handle for performing this switching.

As shown in FIGS. 1 and 2, the open cocoon separating section 12 has a horizontally elongated box 22 and an input port 23 for a cut-out skin cocoon a provided in the box 22 and cut into one side. Incision is made between a cylindrical rotating basket 25 that rotates about a horizontal axis provided with a thin-skin discharge port 24 separated on the other side and a ridge 26 provided on the inner peripheral surface of the rotating basket 25. Incision a-1 made on the cocoon a
, A rotating wing 28 provided in the rotating basket 25 for generating wind toward the discharge port 24 side, and a pupal b discharge conveyor 29 provided below the rotating basket 25. Be composed.

To explain this further, the rotating basket 25 is
A wire mesh 25b is stretched over a plurality of ring pieces 25a to form a long cylindrical body, and a large number of long ridges 26 having a mountain-shaped cross section in the long direction are formed on the inner peripheral surface of the rotary cage 25 at equal intervals. The rotating basket 25 is mounted on the trochanters 30, 30 and the trochanters 30, 30 are driven and rotated by an electric motor 31.
5 is provided with a side plate 32 fixed to the box body 22 side on one side end face,
The inlet 23 is opened in the upper half of the side plate 32, and the side plate 33 fixed to the box plate 22 is also faced to the other end surface of the rotary basket 25. Exit 2
4 was opened. Then, a rotating shaft 35 that is supported by the side plates 32 and 33 to face the center of the rotating basket 25 and rotates in the opposite direction to the rotating basket 25 in conjunction with the electric motor 31 is provided. A total of five wings 28 are mounted at equal intervals at both ends and between them, and a widening claw 27 formed by shaving the tip of a steel rod 27a between the rotary wings 28 approaches the ridge 26. And the ridge 2
The incision made in the skin cocoon a between the skin 6 and the expanding nail 27 was expanded so that the pupa b came out from the thin skin c. The steel rod 27a having the expanding claw 27 formed at the tip is provided between the rotary blades 28 so as to protrude from the rotary shaft 35 in an alternate diametric direction with a phase shift of 180 °. A screw conveyor 29 is provided below the rotating basket 25 along the lengthwise direction thereof, and the screw conveyor 29 transfers the pupae falling from the mesh of the rotating basket 25 to the screw conveyor 7 side.

In addition, a viewing window 22a is provided on the upper surface of the box 22.
, And the rotating basket 25 is also provided with a maintenance door 25c.

As shown in FIG. 4, the separator 6 is sieved with a first sieve 6a with a vibrator and the first sieve 6a.
A second sieve 6b with a vibrator for further sifting the mixture of the pupa and the thin pieces (fibres) remaining on the top is provided, and the thin pieces (fibers) are separated by the first sieve 6a and the second sieve 6b. The pupa thus produced is supplied to the tank 9 by a screw conveyor 37.

To explain this further, the first sieve 6a and the second sieve 6b are stretched between the hopper 38 and the driving roll 39 and the guide roll 40, which are driven and rotated in conjunction with the electric motor 50 in the hopper 38, respectively. Endless conveyor type sieve net 4
1, a vibrator 47 that is driven to rotate in conjunction with an electric motor 42 via belts 43 and 44, a rotating brush 48 that removes pupae clogged in the sieve mesh 41, and a lower part of each hopper 38. The pupa b that has been sieved by the sieve mesh 41 is supplied to the screw conveyor 37 side, and the pupa b remaining on the first sieve 6a is crushed by a crushing roll 46 provided at a lower portion of the outlet side thereof. After being crushed by 46, the second sieve 6
b), and the second sieve 6b completely removes thin skin fragments that are harmful as food contained in the pupa b.

Next, processing of the skin cocoon by the present apparatus will be described. The skin cocoons a supplied from the hopper 10 are sequentially fed between the rubber roll 15 and the rotary blade 14. Then, while the nest cocoon a passes between the rubber roll 15 and the rotary blade 14, one to three incisions are made in the thin skin c and the pupa b
Is also partially cut, and is supplied into the rotating basket 25 from the charging port 23 via the chute 49. Then, the operation of lifting with the rotation of the rotating basket 25 and the operation of dropping under its own weight are repeated, and are gradually carried to the discharge port 24 side by the wind generated by the rotation of the rotating wings 28, during which the inner periphery of the rotating basket 25 is rotated. The pupa b is crushed by the cooperation of the ridge 26 provided on the surface and the expanding claw 27, and the operation of opening the cut made in the thin skin c is repeated, and the pupa b in the thin skin c becomes the thin skin c. The pupa b is discharged from the eyes of the rotating basket 25 by its own weight and discharged from the conveyor 29.
And sequentially sent out to the screw conveyor 9 side. Then, the thin skin c which has released the pupa b and has become lighter is sent out from the outlet 24 to the transport pipe 4 side by the wind generated in the rotating basket 25 and stored in the tank 8. The pupa b is stored in the tank 8 after the thin pieces (fibers) of the skin contained therein are separated by the separator 6.
