Description

[Detailed Description of the Invention] The present invention relates to a cocoon processing device, in which when a perforated plate for immersing the surface in processing water is rotated in the processing tank, the peripheral wall of the processing tank and the edge of the perforated plate are In order to prevent problems such as the treated surface being pinched, crushing the treated surface and damaging the cocoon layer, or contaminating the cocoon layer with cocoon exudate, there are rotating and rotating eyes in the treatment tank. A gutter-like cover concentric with the tank wall is provided between the dish and the processing tank wall.

A cocoon processing device for pre-processing boiled cocoons or processing boiled cocoons,
A cylindrical treatment tank is supported with its axis horizontally, and
The applicant has invented and applied for a device in which a perforated plate that divides the inside of the tank into two is supported coaxially with the above-mentioned shaft, and the perforated plate can be rotated within the processing tank. Depending on the size of the surface, when the perforated plate or processing tank is rotated, the surface may become caught between the edge of the perforated plate and the peripheral wall of the processing tank, resulting in the collapse of the surface and contamination. Occasionally, problems such as surface formation may occur.

Therefore, in the present invention, a cover is provided to cover the perforated plate to prevent the cocoons on the perforated plate from coming into contact with the processing tank wall when the perforated plate is rotated with the processing surface placed on the perforated plate.

Embodiments of the present invention will be described below with reference to the drawings.

1 is a cylindrical processing tank, with a hollow shaft 3 provided at the center of both sides 2, 2. It is supported on a frame 5 by bearings 4, 4 with its imaginary center line horizontal, with the bow as a support shaft.

The processing tank 1 rotates due to the action5.・Return and opening/closing lid □
The opening/closing lid 9 is prevented from opening when the opening/closing lid 9 is turned downward.

Inside the processing tank 1, a cover 16 shown in FIG. 5 is supported by a second hollow shaft 17 rotatably inserted into the hollow shaft 3.

The cover 16 has half-moon-shaped side walls 18, 18 and a gutter-shaped peripheral wall 1.
The hollow shaft 17 is fixed to both side walls 18 degrees 18.

The gutter-shaped peripheral wall 19 is provided with an extremely small distance from the peripheral wall 6 of the processing tank 1, and has an arcuate shape concentric with the peripheral wall 6.

The perforated plate 15 has a flat plate portion 21 between the half-moon shaped 9 side walls 20, 20.
It has a continuous porous plate-like shape consisting of a circular arc portion 22 and a circular arc portion 22, and the circular arc portion 22 has a small distance from the cover 160 surrounding wall 19.

The side walls 20 and 20 are provided with @23°23 rotatably inserted into the hollow shaft 17.

Hollow shaft 3.17. Each shaft 23 has a Cheno foil 24
, 25, 26 are fixed and the motor 27 is installed in the frame 5.
．． The rack passes Cheno foils 33, 34, and 35 between 28.29 Cheno foil 30° and 31.32.

Numeral 40 is a forked arm for opening and closing the opening/closing lid 9, which is supported by a shaft 41, and has a forked portion 42 at the tip that allows the opening/closing lid 9 to be opened and closed when the processing tank 1 is erected.
The protruding pieces 43 on the sides of are fitted together.

A Cheno wheel 44 is fixed to the shaft 41, and the Cheno wheel 44 is fixed to the shaft 41, and the Cheno wheel 44 is fixed to the shaft 41, and the Cheno wheel 44 is fixed to the shaft 41.
Pass 7 on the rack.

4 Btri cocoon supply conveyor, 49 is a leaving conveyor.

Next, the operation of the device of the present invention will be explained.

When loading a new treatment surface into the treatment tank 1, the treatment tank motor 27, cover motor 28, perforated plate motor 2
9, the processing tank 1 is erected as shown in FIG. 6, and the perforated plate 15 and cover 16 are both tilted in opposite directions.

Then, a predetermined amount of the '' side is fed into the processing tank 1 by the supply conveyor 48 from both input and discharge lowers whose lids cannot be opened.

The introduced cocoons are formed by the cover 16 and the flat plate portion 21 of the perforated plate 15; they are deposited on the corner portion.

Next, by rotating the motor 45, the forked arm 40 is brought down, and the opening/closing lid 9 is closed with the forked portion 42 at the tip thereof via the protruding piece 43, and at the same time, the cover motor 28 and the perforated plate motor 29 are rotated. , the perforated plate 15 and the cover 16 are rotated in state 1 shown in FIG. At point A in the figure, since the perforated plate 15 rotates in the seven-counterclockwise direction relative to the cover 16, the treated surface 50 does not get wedged between the perforated plate 15 and the cover 16 at point A.

Under the conditions shown in Fig. 7, treatment plant or treated water is injected from the injection pipe 11, air is extracted from the bleed pipe 10, the pressure inside the tank is reduced, and then the pressure inside the tank is returned to atmospheric pressure.

By this operation, treated water is forced into the cocoon cavity of the cocoon layer, which is in a reduced pressure state.

Next, the positional relationship between the perforated plate 15 and the cover 16 is as follows.
Then, both of them are turned over in the processing tank 1 and brought to the state shown in FIG.
Ru.

As a result, the processing surface 50 is turned over without touching the peripheral wall of the processing tank in a state covered by the perforated plate 15 and the cover 16, and is taken out of the processing port.

Then, the dewatering process is carried out by once again bubbling air into the treatment tank, and the pressure is returned to atmospheric pressure.The cover 16 is left in place in the trench, and the treatment tank 1 and perforated plate 15 are turned to the left in FIG. Rotate as shown.

At this time, since the treated surface is placed on the flat plate part 21 of the perforated plate 15, as the flat plate part 21 inclines, the cocoons fall onto the processing tank peripheral wall 6, and the flat plate between the peripheral wall 6 and the perforated plate 15 It is deposited in the triangular space formed by the shaped part 21.

Also in this case, the peripheral wall 6 and the flat plate portion 21 of the perforated plate 15
Alternatively, the treatment surface 1 is not pushed into the gap with the arcuate portion 22 at all, and the cover 16 is pushed closer to the tank peripheral wall 6.
The movement is like being pulled out relative to the perforated plate 15.

On the other hand, due to the rotation of the processing surface, the cam follower 12 of the opening/closing lid 9 comes into contact with the guide rail 13 and descends, and when the lower end of the guide rail and the cam follower 12 come into contact, the lid 9 is completely bent by its own weight and the inner surface is discharged onto the storage conveyor together with the treated water.

As described in detail above, in the device of the present invention, the perforated plate is rotated within the processing tank; even if the surface placed on the perforated plate is immersed in the processing water or scooped up, the peripheral wall of the processing tank and the perforated plate are removed. A gutter-like force (") is installed in between, and the treated surface can be covered with a perforated plate and a cover, except when the treated surface is being discharged. As a result of the rotation, there is no possibility that the bruising cocoon is wedged between the perforated plate and the peripheral wall of the processing tank, and no damage or contamination due to crushing of the surface occurs.
