Sludge and rough dust can be thereby gathered simultaneously, and the work can be performed without the necessity for a worker to be submerged into the water, and the work is performed safely through four seasons, and a wide range can be cleaned at once by enlarging the width of a take-in port of the raking port.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water cleaning machine operated to remove sludge and dust in rivers, lakes, harbors and the like.

[0002]

2. Description of the Related Art Coarse dust and sludge such as vegetable waste, wood waste, plastic waste, etc. flow into rivers due to runoff of factory wastewater and domestic wastewater, or poor management of the mountains.
It may be floating at a stagnation point or a dam stop point. Such stagnant coarse dust and sludge not only damages the environment and hinders water traffic, but also spoils and gives off an odor, which significantly hinders water quality.

Regarding the water quality, there is a risk that the habitat of seafood will be disrupted and algae will be extinct. In addition, since the water of the river around the city is used as drinking water, it is not only the problem of the presence or absence of odor, but the health problem is very large.
It is said that carcinogenic substances produced by the decomposition of organic substances cannot be removed even by purification. Due to these various problems, efforts are made to remove sludge and dust in rivers, lakes, harbors and the like.

The conventional water-based cleaning machine is of a so-called vacuum type, and the sludge is sucked by the hose by attaching the tip of the hose connected to the vacuum pump to the water surface.

[0005]

According to the conventional above-mentioned water cleaning machine, since the suction action by the hose is used,
Only sludge and small dust could be collected, and coarse dust that could not be sucked by a hose was scraped and removed by a separate operation.

Regarding the work method, since the mouth of the hose is small, it is necessary to move the mouth to the water surface evenly and diligently, which is manual work, and in many cases, in shallow rivers. , It is very hard work for the worker to operate the mouth of the hose by immersing it in the river, and when carrying out by boarding, it requires a worker with a hose in addition to the person who drives it. In addition, the operation of the hose mouth is difficult, which makes the work extremely inefficient.

The present invention has been made in view of the above circumstances.
Not only sludge but also relatively large coarse dust can be collected at the same time, and the collection can be done all at once by simply running on the water.

[0008]

In order to achieve the above-mentioned object, the present invention is provided with a device for scraping coarse dust or sludge floating on the water surface or water bottom at the front end of a body operating on water, and at the rear end. A loading tank is provided in the stacking device, and a coarse dust transport path and a sludge suction feeding path are vertically branched from the scraping device to the stacking tank, and a sorting device is provided at the branching part. An internal impeller for scraping was provided in a cylindrical case having an intake port at the lower part of the front surface, and a dewatering machine for sludge was provided in the suction conveyance path to constitute a water cleaning machine.

In addition, a dust crushing device may be provided in the coarse dust carrying path.

[0010]

[Operation] When the water cleaning machine is operated while operating on the water surface, not only the sludge but also the coarse dust is scraped by the scraping device at the same time, and the coarse dust and sludge are separated by the sorting device, and the coarse dust is transferred. It is thrown into the loading tank by the path, the sludge is sucked into the suction feed path and dehydrated,
It is put into the loading tank.

When the transport path is provided with a crushing device, even if coarse dust is large, it is crushed and densely packed in the loading tank.

[0012]

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

A machine 1 running on water is provided with a coarse dust and sludge scraping device 3, a loading tank 5, a coarse dust transport path 7, a sludge suction feed path 9, and the like.

The body 1 is mounted on a caterpillar 2 running on the riverbed via a column 11, and is vertically adjustable with respect to the caterpillar 2 so that it can be operated at a proper height on the water. In addition, the driver's seat 13
Is provided and is configured so that all operations are performed by the operator. In other words, no other assistant is necessary.

As for the way the body 1 operates on water, the body 1 may be a hull as another method of the caterpillar type. In that case, the scraping device 3 is adjustable up and down with respect to the hull.

The scraping device 3 has a case 15 in which a scraping impeller 17 is installed. The case 15 is formed into a horizontally long substantially tubular shape, and an intake port 19 is opened at the lower part of the front surface. Then, the conveyance path 7 for the coarse dust 10 and the suction feed path 9 for the sludge 12 are connected to the rear side, and a sorting device 21 is provided at the branch portion thereof.

The impeller 17 is provided with a large number of blades of plate material projecting around the rotary shaft, and each blade is curved in an arc shape to improve the scraping ability. Further, if the projections are provided on the inner surface of the arc of each blade, the ability thereof is further improved. Further, it is desirable that the blades are arranged in a staggered pattern.

Other types of the impeller 17 are conceivable, such as a shaft having wire rods protruding from the shaft as blades, a plate material and wire rods arranged in a mixed form, etc. It doesn't matter what form it is, as long as it scratches and.

The coarse dust carrying path 7 is inclined toward the top of the loading tank 5 and is provided with a crushing device 23 at the upper end thereof.
The crushed coarse dust is put into the loading tank 5. Also,
The inclined portion has a grid shape so that only coarse dust is picked up by the impeller 17. Further, the auxiliary conveyor 18 is provided on the lower surface of the lattice, and the auxiliary conveyor 18 is provided with the protrusions 33 for scraping up the coarse dust 10 in a row.

Since the coarse and dust carrying path 7 is formed by arranging the vertical lattice bars in this way, the sorting device 21 is constructed in the same lattice shape as an extension of the lattice bars. In this way, the coarse dust is scraped up along the lattice, and the sludge flows into the suction distribution passage 9 from that interval.

The upper end of the conveying path 7 is horizontally constructed, and a crushing device 23 is constructed by axially supporting a screw there. However, the crushing device 23 uses a cutting blade,
It may be a meshing type of upper and lower gears.

The suction feed path 9 is gathered in the pipe 9a,
A suction pump 29, a dehydrator 31, and a bucket conveyor 9b are sequentially connected to the pipe 9a. Then, the water generated by the sludge hanging on the dehydrator 31 is returned to the river. Further, the dehydrated sludge is carried upward by the bucket conveyor 9b and put into the loading tank 5 from above. 35 is the input port. The dehydrator 31 may be provided at the charging port 35.

[0023]

As described above, according to the present invention, there are the following excellent effects.

1) Since not only sludge but also relatively large coarse dust is collected at the same time, unlike the case where a vacuum hose is used, it is not necessary to collect coarse dust again, and rivers and lakes can be rationalized. , Can clean the port.

2) Since the cleaning is carried out by running the machine over the water, it is not necessary for the worker to be immersed in water, the work safety can be ensured, and the work is easy to carry out throughout the four seasons.

3) The take-in port of the scraping device can be widened, whereby a wide range of the water surface and the water bottom can be cleaned all at once, and workability is very good.

4) Since the sludge is dehydrated and packed in the loading tank, the space of the loading tank is effectively used,
The operation time is long at one time, and work efficiency is also good in this respect.

In addition, when a coarse dust crushing device is provided in the transport path (claim 2), it is suitable for effective use of the space of the loading tank.
