DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a method of thermally decomposing a resin component of a waste FRP ship to effectively use extracted gas and extracted oil.
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an FRP scrap ship demolition work boat capable of efficiently obtaining plate-shaped masses or chip-shaped pieces.

[0002]

2. Description of the Related Art Since FRP ships (fiber reinforced plastic ships) have become widespread in small boats such as fishing boats and pleasure boats, 2
More than 0 years have passed, and the FRP vessels built at that time have been markedly discarded due to aging. The Ministry of Transport estimates that the number of FRP scrapped vessels will reach 50,000 in 45 years, and the Japan Coast Guard has recently tightened its crackdown.

[0003] Therefore, the Ship Technology Research Institute of the Ministry of Transport has started the development of a system for incinerating an entire FRP scrap ship with a trailer. It is equipped with a trailer equipped with a dry distillation furnace for incinerating the resin content of the FRP waste ship, a crusher for crushing the glass fibers of the incineration residue, and a rotary kiln furnace for melting the fibers crushed by the crusher. Can be incinerated at the site where the waste is accumulated.

[0004]

However, the above system is excellent in that it can be incinerated at the site where the FRP waste vessels are accumulated, but it is not only large in facilities but difficult to move on land by a trailer. It took a lot of time to completely incinerate, and it was at present that all incineration was not profitable as a company. In addition, since the dismantling is performed in a living area, there is a possibility that noise pollution caused during dismantling and air pollution caused by scattered fine glass fibers may occur.

Therefore, the present invention is based on the premise that the waste gas and oil extracted by the pyrolysis treatment of the waste FRP ship are not incinerated without being incinerated. It is an object of the present invention to provide an FRP scrap ship demolition work boat capable of efficiently and efficiently dismantling a scrap boat.

Another object of the present invention is to provide an FRP scrap ship dismantling work ship which has solved the problem of air pollution due to noise and glass fiber scattering when the FRP scrap ship is dismantled.

It is a further object of the present invention to provide an FRP scrap ship dismantling work ship capable of crushing a FRP scrap ship on a ship into chip-shaped pieces large enough to be put into a pyrolysis treatment kettle. .

[0008]

To achieve the above object of the Invention The present invention provides a pressing means for compacting the plate the FRP waste boats on board, a site that has been hardened by the pressing means, that site
A drive unit that runs on rails that are set to straddle
A hydraulic cutter means for sequentially cutting in the width direction by a cutter head mounted on a cutter, and crusher means for crushing a plate-shaped mass obtained by cutting with the hydraulic cutter means into chips, for dismantling an FRP waste vessel Was constructed in such a manner that the FRP waste vessel was once hardened into a plate-like material and then cut into a plurality of plate-like lumps on the sea near the port where the FRP waste ship was accumulated, and then efficiently broken into chips. .

Thus, the present invention is designed to reduce the time required for dismantling a single FRP ship and to perform all the operations required for dismantling on the sea outside the living area.

Further, the present invention is provided with a crusher means for crushing a plate-shaped mass obtained by cutting with the hydraulic cutter means on a ship into chips, so that chip-shaped pieces can be formed into a size which can be put into a pyrolysis treatment kettle. It is what was constituted.

[0011]

[Effect] The FRP scrap ship demolition work boat according to the present invention firstly
Collect the FRP waste vessels, remove the engine, screw and other metal equipment from each FRP waste vessel, and then carry the FRP waste vessels on board with a crane etc. from the depot,
After being hardened into a plate shape by a pressing means, it is cut by a hydraulic cutter means into a plate-shaped mass.

The plate-shaped mass may be packed in a box and crushed into chips on land, or the operation of crushing into chips may be directly performed on a ship.

The reason for using the hydraulic cutter means in the above cutting work is that the hydraulic cutter means is excellent in its cutting ability, cutting speed, etc., and that the finely divided glass fibers are scattered by wetting with water during cutting. This is to prevent

Further, by performing the work of dismantling the waste FRP ship on board, the problems of noise pollution and air pollution can be solved at the same time.

As the hydraulic cutter means 9, a commercially available one can be applied. For example, as shown in FIG.
The water pumped from the water storage tank 27 in 6
When the water is supplied to the cutter head 30, the water becomes ultra-high pressure water (arrow A) by the pump unit 28 and is supplied to the cutter head 30 via the control box 29. An abrasive (arrow C) sent from an abrasive hopper 31 operated by a command (arrow B) from the control box 29 is supplied to the cutter head 30 and mixed with ultra-high pressure water to discharge vigorously from the discharge port 30a. It is supposed to be.

The cutter head 30 is mounted on a drive unit 33 which runs on a rail 32 in accordance with a command (arrow D) from a control box 29. Site 4a is cut. By this cutting, a plate-shaped mass 34 is obtained.

As shown in FIG. 5, three cutter heads 30 are equally arranged on a rail 32 so that they can be simultaneously driven and cut off by a command from a control box 29. This aims at shortening the cutting speed, and is not specifically limited to three.

The ultra-high pressure water discharged from the discharge port 30a of the cutter head 30 leaves a high cutting force even at the water pressure after cutting the cut portion, so that a water receiving device (for example, 35 (comprising a ceramic ball material).

Immediately below the water receiving device 35, a sieve (10
A cutting water storage tank 37 is provided via a (about 0 mesh) 36. The sieve body 36 is for collecting the base material separated from the cut site by water pressure at the time of cutting.

The water stored in the cut water storage tank 37 is pumped by a pump 37a, filtered by a filter 38 and circulated to the water storage tank 27. A commercially available filter may be used as the filter 38,
Since abrasive is mixed in the cutting water, a stellite sand filter (manufactured by Stellite, USA) can be used as a filter capable of reliably removing the abrasive. Of course, the water storage tank 27 and the cutting water storage tank 37 may be formed large, and the water used for the hydraulic cutter means 9 may be of a non-circulating type.

The plate-like mass 34 cut as described above is put on a belt conveyor 39, packed in a box 40 in sequence, and stored in a storage 41. Since the plate-shaped block 34 needs to be crushed into chip-shaped pieces in order to be sent to a thermal decomposition apparatus (not shown), the plate-shaped block 34 cut as shown in FIG. The crusher means 43 may be charged into the input port, crushed on the barge 2 and packed in the box 40a.

When the crusher 43 is put into the crusher 43, the chute 42 slides on the plate-like mass 34 and the fountain 42
It is preferable to wash the powdery residue with water by a. That is, it is possible to prevent the blade of the crusher means 43 from being damaged by washing away the powdery slag.

A building 44 is provided on the barge 2 and covers the first press means 7, the second press means 8, the hydraulic cutter means 9 and the crusher means 43. This prevents noise generated during press work and hydraulic cutting work,
This is particularly effective for improving the working environment. In the drawing, reference numeral 45 denotes a power generation facility, and 46 denotes a mooring winch.

Next, the first and second pressing means 7, 8
Will be described with reference to FIGS. Now, the FRP waste vessel 4 carried into the carry-in area 5 is intermittently pressed and transferred by the action of the pusher means 6 (1).
When the transfer is performed by 1 m), the movable press body 19 of the first press means 7 operates as shown in FIG. 7 and crushes the leading portion 4 a of the FRP waste vessel 4. The crushed part has a thickness of 80
cm.

Next, as shown in FIG.
When the movable press body 19 is released, the pusher means 6 performs the following pushing operation, and the crushed portion 4
a is inserted into the press space 21 of the second press means 8.

Thereafter, the horizontally movable press bodies 22 provided on both sides of the press space 21 operate to press the portion 4a from the left and right as shown in FIG. At this time,
Spacing L ₁ between the horizontal movable press member 22, 22, 150c
m.

Next, the vertically movable press body 23 is pressed as shown in FIG. 10 while the horizontally movable press bodies 22, 22 are pressed. Distance L ₂ between the vertical movable press member 23 and press table 11 is optionally adjusted. That is, when the FRP waste vessel 4 passes through the second pressing means 8 by repeating the above operation, it is sequentially formed as a plate-like object having a width of 150 cm.

Next, the operation of the hydraulic cutter means 9 will be described.
(Arbitrary thickness) and molded into a plate,
If you cut four places, 14 places x 1.5m = 21m
When three cutters having a cutting speed per cutter head of 400 mm / min are used, 21 × 1,000 mm = 21,000 mm 21,000 mm ÷ (400 × 3) = 17.5 minutes, the cutting time of a 15m long FRP scrap ship is 17.5 minutes.
Minutes.

Therefore, assuming that 10 FRP waste vessels are to be dismantled daily, 17.5 minutes × 10 vessels = 175 minutes (about 3 minutes).
Time), and other times (for example, various times such as the time for port entry and anchorage of a work boat, the time for loading from a dumping site of FRP waste vessels to the loading area for one ship by a crane, and the time for pushers and presses). It is enough to take about 5 hours even if you take into account that 10 FRPs are required for 8 hours a day.
It is a calculation that can be handled by abandoned ships.
