Description

Apparatus for removing sediment of floor

The present invention relates to a removal device for removing a bottom sediment (journey) such as a lake, reservoir, dam or river. More specifically, the present invention relates to an apparatus for removing a bottom sediment of an appeal for removing low specific gravity jersey in closed water.

Generally, rainfall in the basin flows through the tributaries to lakes, reservoirs, dams or rivers. In this case, various contaminants and soils on the surface are introduced together to cause water pollution. Particulate matters are deposited on rivers and lakes, and these deposits contain various kinds of pollutants, soils, heavy metals, nitrogen, phosphorus, etc. Contains many nutrients, causing a lot of problems.

In particular, organic matter and soil powder are easy to settle in areas where the flow rate of closed water is slow or near river basins, and sediments having a low specific gravity among the sediments are organic substances that consume dissolved oxygen in raw water. Containing pollutants deteriorates the water quality, and algae, etc., grow abnormally due to eutrophication, and harmful gases are generated and the self-cleaning ability of lakes, reservoirs, dams and rivers is lost, and the pollution is accelerated.

In addition, low-density sediment is located at the top of the sediment is precipitated, and even a small external force is easily diffused in the water is a major cause of worsening the water quality.

In the dredging method of removing sediment, the crane installed in the dredger is equipped with a bucket for raising soil and pollutants, and the bucket pulls up the pollutants on the lake bottom and throws the pollutants into a separate collection site. .

However, this dredging method has a problem of causing secondary water pollution when contaminants composed of mostly light suspended solids are diffused in the water by vortices of water generated by the bucket when the pollutants are lifted into the bucket. . In addition, a dredger equipped with a crane not only discharges pollutants from itself, but also has a problem in that a dredging operation is expensive.

Moreover, in closed waters where the need for increasing freshwater capacity is low, it is necessary to dredge the low specific gravity of the upper layer, which is mainly composed of organic matter, rather than dredging the entire basin. It cannot be achieved.

In addition, there is a dredging method that discharges contaminants on the lake bottom along with lake water by using a pump. In this dredging method, since the diver enters the water and works, the economic efficiency and stability are reduced. Since the damage occurs to the motor when entering, since the net is attached to the suction port of the dredging pipe connected to the motor, there is a problem that can not be sucked and dredged small garbage on the lake bottom. In addition, there is a problem that the pump itself used for dredging is expensive, as well as continuously supply power.

Therefore, the present invention was devised to meet the above requirements, and by using the difference of water head to raise the joule of appeal, it is possible to efficiently remove the joule with minimal power use. It is an object of the present invention to provide an apparatus for removing the bottom sediment of the appeal.

In addition, the present invention has another object to provide a floor sediment removal device of the appeal that can reduce the size of the facility, while maintaining a stable low pressure suction force required for low specific gravity dredging dredging.

It consists of a screw 22 fixedly installed at the tip of the extended shaft of the rotating shaft from the outside.

Here, the rotation shaft 20 is installed eccentrically to one side with respect to the center of the suction pipe 11, for this purpose to form a housing so as to project outward on the side of the suction pipe 11, as shown in Figure 3, The rotating plate 21 to be installed is prevented from being caught in the suction pipe.

Therefore, when the rotating plate 21 is rotated by the water flow force pulled along the suction pipe 11, the screw 22 installed on the rotating shaft 20 is rotated to move the water tank 10.

Unexplained reference numeral 19 is a solenoid valve installed on one side of the discharge pipe.

On the other hand, according to an embodiment of the present invention in order to continue to maintain the head difference of the water tank 10, the water and Journey continuously introduced into the water tank through the suction pipe 11 should be discharged from the water tank.

To this end, the present removal device further includes a scoop treatment facility connected to the water tank 10, as shown in FIG.

Therefore, the treated water containing the Journey is introduced into the washing tank while a part is bubbled in the bubble generator through the branch line and is introduced into the washing tank through the bubble supply pipe.

As the treated water is activated in this continuous process, sludge is injured by bubbles.

Hereinafter, the operation of the above-described deposit removing device will be described.

The head pox can be obtained by floating the floating line 30 on the river. The water tank 10 connected to the floating line 30 floats on the river and descends to a certain depth below the water surface by the weight of the floating ship 30 or the water tank 10, and thus, the bottom of the water tank 10 and the steel top Due to the height difference with the surface of the water head will be generated in the water tank (10).

When the water tank 10 and the floating line 30 floated on the river is stabilized, the depth gauge 16 installed on the bottom of the water tank 10 accurately measures the distance between the bottom surface of the water tank 10 and the jersey layer.

The signal measured by the depth gauge 16 is applied to the controller 17, and the controller 17 calculates the distance difference between the distal end of the moving tube 12 and the jersey floor by calculating a numerical value according to the signal. 12) to control the drive motor 13 to lower.

When the drive motor 13 is rotated in reverse by the signal of the controller 17, the drum 14 installed on the rotation shaft 20 of the drive motor 13 rotates to release the chain 15, and at the end of the chain 15 The moving tube 12 connected is descended along the suction tube 11 by its own weight.

When the moving tube 12 drawn out through the end of the suction tube 11 reaches the bottom layer of the appeal, the driving motor 13 stops the operation and stops the moving tube 12 at the current position.

As the moving pipe 12 reaches the bottom of the tank, the bottom of the appeal is sucked into the water tank 10 along the moving pipe 12 and the suction pipe 11 by the head difference generated in the water tank 10.

In this way, the present invention can dredge the jersey by the water head without using a separate power, and the dredged jersey is sent to the floating tank through the discharge pipe 18 installed into the water tank 10.

That is, by continuously discharging the jersey and water drawn up through the suction pipe 11 through the discharge pipe 18, it is possible to continue to maintain the head of the head within the water tank 10.

Here, the water head difference in the water tank 10 is always kept constant by the balance of the amount discharged through the discharge pipe 18 and the amount introduced into the water tank 10 through the suction pipe 11, the reason is as follows.

When the water level in the water tank 10 is increased and the head difference is reduced, the amount of water and the joule flowing through the suction pipe 11 is reduced, and the discharge pipe 18 is fixed through the pump 31 installed at the outlet side. As the amount of water and Journey continue to be discharged, the amount of water discharged from the amount of water is lowered again, thereby lowering the surface of the water tank 10 to increase the head of the head. In addition, when the water level in the water tank 10 is lowered and the water head difference is increased, the amount of joules and water introduced through the suction pipe 11 is increased, thereby reducing the water head difference in the water tank 10.

Therefore, it is possible to keep the same head pox.

In addition, the tank and the water tank 10 is moved along the river according to the suction and the water is sucked through the suction pipe 11, and the water and the reservoir to move upward along the suction pipe 11 is installed inside the suction pipe (11). While hitting the rotating plate 21 to rotate the rotating shaft 20 is installed, the rotating plate 21, the screw 22 installed on the rotating shaft 20 from the suction pipe 11 is rotated to generate a driving force along the steel plate The tank 10 will be moved.

As the water tank 10 moves, the tip of the moving tube 12 is moved to a new jersey layer so that the suction of the jersey can be continued.

Here, the distance difference between the end of the moving tube 12 generated by the movement of the water tank 10 and the bottom jog layer is newly detected by the depth measuring instrument 16 which is operated at a predetermined time interval according to the timer operation, and the detected signal is applied. The received controller 17 controls the drive motor 13 again to correct the distance difference.

On the other hand, the post-treatment of the Journey flowed into the water tank 10 is as follows.

As the suction pump 31 installed in the flotation line 30 operates, the spool and the water in the water tank 10 are transferred to the washing water tank 32 through the discharge pipe 18.

By spraying the ultra-fine force gun on the discharge water introduced into the washing tank 32, the floating sludge contained in the discharge water is floated to the surface. Here, the ultra-mini strength foam can be formed by mixing water, air (oxygen) and chemicals (coagulants).

When the pressurization is carried out, the floating sludge is floated on the surface of the water, and the floating sludge injured on the water is removed from the surface by the sludge sludge remover 34 and accumulated.

In addition, the discharged water overflows and is passed to the settling tank 36, the fine settling sludge is settled on the bottom surface in the settling tank 36, the precipitated sludge is collected by the settling sludge baffle.

The accumulated floating sludge is dehydrated and dried in the sludge flocculation tank 35, and the leachate soaked in the floating sludge is dehydrated by natural drying, and the dried sludge is incinerated, landfilled or Recycled as compost.

The final treated water from which the sludge is removed through the above process is discharged through the drainage system 37.

According to the device for removing the bottom sediment of the appeal according to the present invention as described above, by minimizing the use of power and underwater work, there is an effect that can reduce the manpower and cost according to the dredger.

In addition, it is possible to efficiently suck only the jersey floor regardless of the topographical variation of the riverbed.

In addition, by dredging dredgers only at the bottom of the river, the dredging equipment can be reduced in size, and the treatment efficiency of the collected polluted water can be increased.
