For example, it may be arranged to be inserted into the lower portion of the screen 332 from the side of the housing 330.

The jetting unit 320 is connected to the air supply pipe 321 and is formed into a tubular shape and has a spray hole 320a.

Meanwhile, the jetting unit 320 is installed inside the housing 330.

The housing 330 has a triangular shape when viewed from the front, and is formed such that both the front and rear surfaces are closed, and only the bottom portion is opened.

A guide 331 in the shape of a ski plate is provided on the bottom of the housing 330 and the tip of the guide 331 is formed to protrude upward.

A screen 332 is provided in a planar shape inside the housing 330 and an air vent 333 is installed at an upper end of the housing 330.

The housing 330 is connected to a height adjusting device 340 formed of a winch or the like by a connecting line 341. The connecting line 341 is configured to be able to be rolled or unwound by the height adjuster 340 while accommodating the height variation of the height adjuster 340, such as a wire.

In the present invention, the air supply pipe 321 and the discharge pipe 430 are formed in a flexible form such as a hose to be able to accommodate the height change by the height adjuster 340.

The junitary sludge suction unit 400 includes a suction pipe 410 installed on the upper portion of the housing 330, a suction pump 420 connected to the suction pipe 410, and a discharge pipe 420 connected to the suction pump 430. [ (430).

The suction pump 420 is installed in the main body 100 or the main body 200 as a general pump of a known configuration.

The discharge pipe portion 430 has a discharge pipe 431 for discharging the sanitary sludge sucked in the suction pump 420 to the sanitary sludge rejection unit 400.

One end of the discharge pipe 431 is connected to the suction pump 420 and the other end is disposed on the upper part of the sanitary sludge rejection 400. A valve 431a is connected to the line leading to the sanitary sludge rejection 400 Is installed.

A branch pipe 432 branched before the valve 431a is formed in the discharge pipe 431 and the end of the branch pipe 432 is connected to the flow pipe 311 in the bubble refinement unit 310

An inner sludge 510 having a dense mesh size is formed on the inner side of the sludge rejection unit 500 and an outer sludge 520 is formed on the outer side of the sludge rejection unit 500 having a mesh size larger than that of the inner sludge sludge 510 .

That is, the inner sieve 510 is formed of a mesh of a size that allows water to be easily drained while preventing outflow of juniit.

In addition, the outer sifter 520 supports the inner sifter 510 and forms a mesh larger than the inner sifter 510 to smoothly discharge the water. In order to improve the strength of the inner sifter 510, It is preferable that it is made of reinforcing steel or the like.

The inner sieve 510 and the outer sieve 520 may be formed to form a double layer or alternately to form a double layer.

The junitary sludge rejection 5110 having such a configuration is installed on one side of the top surface of the body 200 so as to be located in the space 210.

At this time, it is preferable that the sanitary sludge rejection unit 110 is installed higher than the water surface so that the water contained in the collected sanitary napkins can be easily discharged.

In other words, when the lower portion of the junitary sludge rejection 110 is positioned so as to be submerged in water, the water contained in the junito can not be smoothly discharged. Therefore, the water contained in the junito The discharge can be smoothly achieved.

In addition, the sanitary sludge rejection unit 110 may be installed on each of the bodies, or may be installed on the body through a separate bracket (not shown).

Next, the operation of the junitary sludge collecting device constructed as described above will be described.

In order to collect the junitary sludge, it is necessary to move from the water surface to the position where the collection operation is to be performed. In the junitary sludge collecting apparatus 10 of the present invention, the dead bodies 200 are spaced apart from each other, So that the water surface of the lake or the like simultaneously acts to reduce the movement resistance by the water to facilitate the movement.

In addition, various facilities for removing the junitot sludge, such as the height adjusting device 340, are installed in the space 210 between the bodies 200, and the sludge can be collected easily.

If there is no space 210 between the supports 200, the device must be installed at the end of the support 200, so that it is not easy to secure a space for installation and a problem is likely to occur in securing the support center.

Next, the height adjusting device 340 according to the present invention is operated to wind or unwind the wire 341 connected to the housing 330 to position the housing 330 so as to land on the bottom of the water at the working position.

In the present invention, the installation height of the housing 330 can be adjusted by the height adjusting device 340, so that it is possible to arrange the housing 330 appropriately according to the height of the bottom of the water at each working position .

In addition, when the jitters sludge collecting device 10 is moved, the housing 330 is lifted through the height adjusting device 340 to prevent interference with rocks, aquatic plants, or depressions bent in the water, And the working efficiency can be increased.

The guide 331 provided at the bottom of the housing 330 serves to prevent the housing 330 from being caught in the jiniton when the housing 330 is moved.

The water containing the sludge sludge supplied through the branch pipe 432 flows into the flow pipe 311 of the bubble atomizing apparatus 310 and flows into the interior of the fine filter 312. At this time, The compressed air is supplied through the inlet 313.

The air supplied through the injection port 313 flows into the water through the fine pores 312a formed on the surface of the fine filter 312.

At this time, the air introduced through the fine filter 322 is further reduced by the shearing action of the pressurized raw water, so that the air is formed into very small microbubbles.

The coagulant supplied from the chemical tank 103 is mixed with the water in which the microfused bubbles have been dissolved through the bubble refinement unit 310 and then is mixed with the coagulant supplied from the chemical tank 103 through the spray hole 320a of the spray unit 320, Toro is sprayed.

In the present invention, the pressurized water is injected into the interior of the housing 330 to disturb the junits, thereby disturbing the sludge contained in the junit.

In addition, the fine bubbles contained in the pressurized water are sprayed, and the surface of the sand or gravel of the junito is also cleaned.

As mentioned above, the sludge separated from the gravel or sand of the junite is agglomerated and then adsorbed on the micro-bubbles having a light weight, so that the float can be easily floated to the upper part. .

Next, when the pump 420 is operated, the disturbed and coagulated jitto sludge flows along with the water through the suction pipe 410.

The lower end of the suction pipe 410 is spaced apart from the bottom of the water, so that sand, gravel and the like are not sucked into the suction pipe 410 due to their own weight.

In addition, since the lower end of the suction pipe 410 is installed higher than the filter 320 installed in the middle of the housing 330, the foreign substance such as a leaf is sucked into the suction pipe 410 .

In addition, micro-bubbles are generated inside the housing 330, and the micro-bubbles are generated on the inner upper surface of the housing 330. The efficiency of the pump 420 is reduced when the minute bubbles flow into the pump 420 through the suction pipe 410. It is preferable that the minute bubbles do not flow into the suction pipe 410 as much as possible.

Therefore, in the present invention, an air vent 333 is provided at an upper portion of the housing 330 to act to discharge fine bubbles which are gathered on the upper surface of the housing 330.

The lower end of the suction pipe 410 is located below the upper inner surface of the housing 330 to prevent the minute bubbles generated inside the housing 330 from being introduced into the suction pipe 410.

As described above, in the present invention, since the jitney sludge disturbance, flocculation, flooding, and suction are performed in the housing 330, the water outside the housing 330 is basically blocked by the housing 330, And has the advantage of performing the toe sludge collection work.

Since the guide 331 is provided on the bottom surface of the housing 330, the housing 330 is formed so as to be spaced upward from the bottom surface of the water, through which the water to be treated flows.

On the other hand, the sanitary sludge sucked by the suction pipe 410 passes through the suction pump 420 and flows out to the discharge pipe part 430.

The sludge sludge is discharged together with the water through the discharge pipe 431 of the discharge pipe portion 430 and transferred to the sludge sludge rejection unit 500.

Meanwhile, a part of the water mixed with the jitto sludge is also transferred to the branch pipe 432 branched from the discharge pipe 431 and used for driving the bubble refinement device 310.

It is possible to simultaneously control the amount of junitor sludge discharged by adjusting the valve 431a provided in the discharge pipe 431 and the amount of mixed sludge sludge supplied to the branch pipe.

In the present invention, the suction of the sludge sludge and the driving of the bubble refining apparatus 310 can be simultaneously performed by the single pump 420. When the water necessary for the bubble refining apparatus 310 is to be driven by a separate pump It is advantageous in that the apparatus can be configured simply.

The water mixed with the jitto sludge discharged from the discharge pipe 431 is transferred to the sludge sludge rejection 500 and passes through the inner sludge network 510 and the outer sludge network 520 to drain water and to remove sludge contained in the sludge Thereby preventing secondary water pollution caused by re-emission of the gyNT sludge.

On the other hand, in the case where the receiving sludge is large in the junitary sludge rejecting unit 500, the sludge is further dehydrated through a dehydrator (not shown), and only the dehydrated sludge is separately transported, It is possible to secure a free space in the rejection 500.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, And will be apparent to those skilled in the art to which the present invention pertains.
