Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention is directed to water hyacinth (water hyacinth) and the like. This invention relates to a water treatment method that efficiently performs treatments such as collection of standard aquatic plants.

[Conventional technology]

Traditionally, the method of processing incoming trains was to
A method of only doing this...(1) Water in a state of natural growth;
A method (2) for recovering < as it is is known.

Furthermore, after cutting and collecting the aquatic plants, the aquatic plants are subjected to solar heat...(3) or in-furnace treatment...(4)
dehydrate and reduce bulk volume.

Aquatic plant treatment methods are known that attempt to make subsequent treatment more efficient.

[Question 8 to be solved by the invention] However, the above-mentioned conventional method (1) does not collect only by cutting, so even if it becomes small pieces, it is not an effective method at all for those with strong breeding power of water 9. In addition, there is a problem that not only small pieces of rotten aquatic plants turn into sludge and settle on the bottom of the water, producing Mizuga dirt S1, which is contrary to efficient treatment of aquatic plants.

Further, even if an attempt is made to collect water to 1° in the state of natural growth 71+ as in the conventional method (2), the recovery efficiency is poor because the state of natural growth 7B remains as it is.

Furthermore, cut aquatic plants as in conventional method (3).

The method of dehydrating using solar heat after collection has a problem in that the dehydration efficiency (i) is low.

In addition, the in-furnace treatment as in the conventional method (4) has the problem that it is not possible to efficiently dehydrate Tenharu no Mizu 1:, which is expensive.

The present invention was proposed in order to solve the above-mentioned problems, and an object of the present invention is to provide a tree I7 processing method that efficiently processes buoy type trees.

[Means for solving problems]

The present invention of fS1 is to solve the above-mentioned problems, and is an aquatic plant treatment method in which aquatic plants are cut and collected by a water treatment vessel, and then the collected aquatic plants are pressed by mechanical force and dehydrated. It's a method.

The present invention of :iS2 is to use a :fSl aquatic plant processing vessel to precursor aquatic plants, and then a second aquatic plant processing vessel to further cut and collect the cut aquatic plants.
v processing method.

〔Example〕

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described based on embodiments thereof with reference to the drawings.

First, a method according to an embodiment of the first invention will be described.

First, the aquatic plants are cut and collected by an aquatic weed processing boat.Next, the collected aquatic plants are pressed by mechanical force and dehydrated. This mechanical force is not particularly limited by using a rotary machine, an automatic press machine, etc., and an automatic press machine or the like as a suppression means may be installed in the aquatic weed treatment vessel.

This process dehydrates and reduces bulk, making drying faster and more efficient. In addition, subsequent land transportation and the like can be performed economically and efficiently.

Next, a method according to an embodiment of the second invention will be described.

First, aquatic plants are pre-cut using a first aquatic plant processing vessel.

Thereafter, the carted aquatic plants are further cut and collected by the FG2 aquatic plant processing vessel.

It goes without saying that the number of cuts made by the first and Em2 aquatic plant treatment vessels is not particularly limited.

Since the first aquatic weed processing vessel pre-cuts the aquatic weed, the aquatic weed becomes sufficiently small pieces. Therefore, the cutting and collection work by the second aquatic weed processing vessel can be easily and efficiently performed.

In addition, an example of an aquatic plant treatment vessel used in the first and second embodiment methods of the present invention is shown below.

First, :ttJl for cutting in the present invention and the second
An aquatic plant processing vessel having only a pre-cutting function according to the present invention will be described.

Figure 1 is a perspective view of this aquatic weed processing vessel, which consists of a cutter vessel A. The hull 10 has a pair of left and right floating bodies 11a.
The floating bodies 11a and flb are connected in the width direction by a bridge 13 to form an integrated structure.

The entrance 114 of the passage 12 is funnel-shaped and opens in the front, and is designed to attract aquatic plants within the width and turning range of the hull 10 into the passage 12.

At the bow of the floating bodies 11a and llb, there is water! It is equipped with a rotary cutter 15 that has the functions of mowing, cutting, and reversing. The water cut by the rotary cutter 15 passes through the passage 12 and flows to the rear of the canterboat A.

The rotary cutter 15 has a blade 17 that directly cuts and cuts aquatic plants. It is comprised of a shaft 18 that fixes it, and a drive section 19 that rotates the shaft 18.

To connect the rotating shaft 18 to which the blade 17 is fixed and the drive section 19, an endless rubber belt 20, a chain belt, or the like may be used as an intermediate medium, or a direct shaft drive method may be used.

The rotating direction of the rotating shaft 18 to which the blade 17 is fixed is
It is configured to rotate in a direction that accelerates the progress of O. With this configuration, plate 17. Rotating axis 1
8 as well as drive il! The rotary cutter 15 consisting of a 119 is capable of trimming, cutting, and cutting aquatic plants floating in the front water area of the hull 10 in a manner such that they are caught in the water, and then sent to the rear.

In addition, the aquatic weed treatment ship shown in Figure 1 uses a rotary cutter 15.
is integrated across the left and right floating bodies 11a and Llb, but as shown in FIG. 11a.

Even if it is placed in the 11biiJ section, there is no change in its function of cutting aquatic plants 15 times like the integrated rotary cutter and sending it to the lowest amount of power.

Also, the shape of play F'17 is not an upright type.

As shown in Q'531K (a) and (b), the blade type has a curved blade 17 from the blade base 17a to the blade edge 17b, and the plate 17 has a moderate bend, so that the blade 17 of the water f and the rotating shaft 18 It is possible to prevent entanglement.

Although the play F' 17 can fully demonstrate its function with a thin plate, when more fine pieces of aquatic plants are required in the effective utilization treatment of aquatic plants, a sharp blade is attached to the peripheral part 17c of the plate cut exception. You can increase your ability to cut aquatic plants.

Alternatively, the periphery m l7c on the cutting side of the blade may be shaped like a saw blade.

Further, the number of blades 17 is determined by the length of the rotating shaft 18 of the rotary cutter 15 *width of the hull 10) and the type of water to be collected.

The plate 17 may be fixed to the rotating shaft 18, but in order to facilitate maintenance, inspection, and replacement of the plate F17, a socket 23 having a bolt hole 21a is fixed to the rotating shaft 18, and a socket 23 with a bolt hole 21a is fixed to the rotating shaft 18. It is convenient to use a connection type in which a blade 17 having a similar bolt hole 21b is inserted and both are connected with a bolt/nut (not shown).

Furthermore, even if the blade 17d has a shape in which only the tip of the plate 17 is bent to one side (as shown by the broken line in FIG. 3(b)), the effect is the same as that of the planar blade 17.

The plate 17 can be attached to the rotating shaft 18 by attaching one blade 17 to the cross section of the rotating shaft 18.
If the purpose is to collect water 9 that has been fragmented into smaller pieces, the effect can be expected by attaching two or three blades 17 to one cross section. In addition.

It is preferable that the blades 17 are arranged so that they are not installed at the same mounting position in the cross section.

Also, unlike other parts, the implantation density of the blades 17 is increased in the parts near both ends of the one-rotation shaft 18. This is to make the cutting and separation of the collected aquatic plants and the aquatic plants that escape to the rear outside of the hull 10 more effective.

In addition, the rotary cutter 15 is as shown in FIG.
In addition to the rotary cutter 15 (referred to as the front rotary cutter), a rotary cutter 15 used in the same manner as the rotary cutter 15 is installed at any position in the passage 12 between the floating bodies 11a and llb behind this rotary cutter 15.
It may be equipped with a (referred to as rear rotary cutter).

Of course, the front rotary cutter 15 alone can demonstrate its ability for cutting and rearward cutting of aquatic plants, but by arranging the rotary cutters 15 and 15a in two stages, front and rear, it is possible to cut aquatic plants into smaller pieces. The vessel can be separated into pieces and transported backwards more smoothly, allowing it to fully demonstrate its capabilities as an aquatic weed treatment vessel.

Cutter ship A has a propulsion screw 25 so that it can self-propel.
This propulsion screw 25 is connected to the engine 2.
5a. In addition, floating aquatic plants and wood,
An anti-M net 26 is provided on both sites of the propulsion screw 25 to prevent harmful floating substances such as bamboo and vinyl from being entangled, maintain symmetrical operation without being affected by these substances, and perform efficient processing. installed. Although the rear and bottom portion of the propulsion screw 25 may also be covered with a net, it is preferable that the protective net 26 be attached only to both sides. The reason for this is that there is less power loss.

Rotary cutter 15.15a, propulsion screw 2
5 may be operated remotely from a control platform 27 provided on the floating body 11a to facilitate navigation.

The front rotary cutter 15 and the rear rotary cutter 15a may use the same drive source, or may be made independent of each other.

Next, an embodiment of the aquatic plant treatment vessel having the cart/cart and collection function used in the first and second aspects of the present invention will be described with reference to FIGS. 5, 6, and 7. do.

Honsui Luo's processing ship has a fiS that only has a cutting function.
Since the aquatic weed processing boat shown in Fig. 1 has an aquatic weed collection function, a collector B is provided with a rotating wire mesh 60 and a one-rotation wire mesh 60, thereby making it possible to capture floating matter.

As shown in FIGS. 5 and 6, a rotary cutter 15 is provided immediately before the rotating wire mesh 60. In other words, a rotating wire mesh 60 for charging aquatic plants into the collector B is arranged in the passage 12 for collecting aquatic plants immediately after the rotary cutter 15 provided at the bow of the floating bodies 11a and 11b, close to the rotary cutter 15. .

In addition to the ability to mow and cut aquatic plants by involving them, the rotary cutter 15 has a backward feeding force by making the plate 17 curved. 0-rotating wire #11 is forcibly placed on the rotating wire mesh 60.
60 is rotatably supported by a rotation support device 61 and rotated by a drive source (not shown). An elevating wire mesh 62 is disposed between the rotary cutter 15 and the rotating wire and the mesh 60.

The vertical wire mesh 62 is supported by a support part 63 and moves up and down. The zero-rotation wire mesh 60 rotates clockwise when viewed from the right hand toward FIG. 5, and is positioned upward as shown by the solid line in FIG. Next, it is reversed counterclockwise and positioned downward as shown by the single point vQ line in FIG. The material passes through and is loaded onto the rotating wire mesh 60.

Further, when the rotating wire mesh 60 is positioned upward as shown by the solid line in FIG. Block the passage. This operation is used to perform cutting and collection work.

The rotating wire mesh 60 has a mesh shape as shown in FIGS. 5 and 6.

Thereby, aquatic plants can be placed on the rotating wire mesh 60 itself without interfering with the flow of water.

In other words, the rotating wire mesh 60 is not affected much by the speed relative to the water.

The drive source of the rotating wire mesh 60 may be a type directly connected to the rotating shaft,
Further, the rotating shaft and the drive source may be connected by a medium such as a rubber belt or a chain belt.

+iFi section rotary rotary cutter 15. In the case of the embodiment of a double rotary cutter set with a rear rotary cutter 15a, the one-turn wire gauze 60 is placed not immediately after the front rotary cutter 15, but at the rear rotary cutter 15.
It is placed immediately after a.

Collector B can be of any shape as long as it can store the collected trees, but the collector
Dehydration treatment and frying of water hyacinth, where % is water
For convenience, a raised floor type collector 30 will be described below as an example.

The raised-bed double-barrel collector 30 has a mesh-type floor 31 for drainage, as shown in FIG.

The recovery unit 33 is comprised of a mesh-type wall 32 extending above the periphery of the floor 31. Although aquatic plants may be piled up directly in this collecting section 33, in order to facilitate more efficient unloading of aquatic plants from the first collecting section 33, a net 34 is disposed inside this collecting section 33, and Pile up aquatic plants. Then, the aquatic plants are lifted up together with the net 34 using a crane or the like, and then unloaded onto land or onto a transport vehicle such as a truck. The mesh type floor 31 is supported by floating bodies 35 placed on the left and right sides.

Although the floating body upper surface 36 may be used as a part of the mesh type floor 31, a support 37 is provided between the mesh type floor 31 and the floating body 35, and the mesh type floor 31 is connected to the floating body 35 via the support 37. If they are integrated, more effective drainage can be achieved.

The stilt-type twin-hulled collector 30 is connected to the cutter ship A by a connecting rope 16 and towed.

Loading and unloading of aquatic plants to the collecting section 33 is carried out by the cutter ship A using a sunken rotary wire and a net 60.

This aquatic weed processing vessel is configured as described above, so if the aquatic weeds are not in a state of natural reproduction, such as floating or growing even when they are dormant or in clusters, in other words, the aquatic weeds are cut into small pieces due to artificial damage. By taking advantage of its ability to float even when compressed or compressed, it is possible to cut aquatic plants appropriately, change them into a form that is easy to salvage, and then collect the aquatic plants from the surface of the water in the collection unit, instead of pulling them out of the water all at once. It is.

That is, when collecting water ψ in this aquatic weed processing vessel, the aquatic plants are salvaged after being transformed into a form that is easy to collect. This is the reason why the collection rate of aquatic plants is dramatically higher than conventional ones, and the operation is efficient and inexpensive.

The lower part of the rotary cutter 15 is submerged in water, and the plate 17 rotates backward in the submerged part and rotates forward on the water surface. Therefore, a water flow is generated by the rotation of the rotary cutter 15, and the aquatic plants cut by the plate 17 are cut by the blade 17 and continuously transported rearward on this water flow.

The cut aquatic plants do not stay in the bow part of the ship and flow backwards toward the hull 10, so that the vessel can sail without being hindered by the aquatic plants even in a water area where aquatic plants are abundant.

If the rotary cutter 15 is placed in front of the rotating wire mesh 60, the aquatic plants forcibly transferred backward by the rotation of the plate 17 will be restrained in the space between the blade 17 and the rotating wire mesh 60, but the rotating wire mesh 60 will When the machine is operated, the aquatic plants that have been forcibly transferred are placed on the rotating wire mesh 60 one after another.

As a result, it is possible to unload more reliably and efficiently than a method in which aquatic plants are picked up directly by a conveyor.

Furthermore, the water flow generated by the rotary cutter 15 also acts as a propulsive force.

Furthermore, as described in 1, although not shown in the drawings, an automatic press machine for suppressing aquatic plants may be incorporated.

〔Effect of the invention〕

As explained above, the present invention has the effect that buoy type aquatic plants can be treated efficiently.
