Description

[0001] AIR-LIFTING DEVICE [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air-lifting device, and more particularly, to an air-lifting device capable of increasing foreign matter removal efficiency while preventing disturbance in a vessel when discharging foreign matter to the outside.

A typical air-lifting device consists of a tube for injecting air (or compressed gas) and a tube for draining water. In the air-lifting device, an air pipe having an air amount adjusting valve is piped to a pumping water pipe opened in the sludge layer at the bottom of a settling tank, and air is blown into the tip portion. As a result, bubbles are contained in the liquid inside the amniotic fluid tube, and the apparent specific gravity is reduced, so that the amount of liquid equivalent to the difference in specific gravity between the inside and outside fluid of the inside of the amniotic fluid tube is transferred.

The advantage of the air-lifting device is that it has few faults because it has no moving parts and it can freely regulate the amount of water by adjusting the amount of air. However, because of using compressed air, the power efficiency is usually lower than the centrifugal pump. Also, since the difference in specific gravity of the liquid inside and outside of the pumping tube is used, it is not possible to pump all of the liquid in the tank.

When the water is discharged by the air-lifting device, some foreign matter in the tank is discharged together with water. As the actual air pressure enters the tank, the foreign matter in the tank is changed into a floating state, . In other words, the foreign matter in the trench is very small, ranging from fine grains to small sand size, which can take several days to sink if once floated.

When the general air-lifting technique is applied, fine particles are made to float due to the disturbance caused by flowing into the discharge pipe, and the fine particles are hardly removed even after the construction. Rather, it is in a floating state for a long time, so it sinks back to the floor or gets caught on the screen.

Wherein the suction pipe is connected to one end of the discharge pipe with a funnel shape having an outer circumferential surface in contact with an inner wall of the pipe, and the air introduced through the air inlet pipe does not disturb the foreign substance, So as to efficiently discharge the foreign matter. The lower packer is inserted into the canal so as to abut the inner wall of the canal, and is disposed below the canal. The pulse discharge device is disposed between the suction pipe and the lower packer, and generates a plasma to drop clogging material in the screen or the wall of the wall. In this case, a hole is formed in the suction pipe so that one end of the discharge pipe is penetrated, and the lower area of the suction pipe is concave so as to have a funnel shape, and the suction pipe and the lower packer form a double packer, The plasma generator generates a plasma within the double packer interval by the pulse discharge device, so that the foreign matter adhering to the screen or the wall of the vessel is separated from the screen or the wall of the vessel , High pressure air is injected from an external air source through the air injection pipe and air bubbles are generated in the groundwater in the pipe, so that water having a specific gravity smaller than the specific gravity difference is discharged to the outside through the discharge pipe.

The air injection pipe 120 provides a path for injecting the air (or compressed gas) provided from the air source into the discharge pipe.

The suction pipe 130 is connected to one end of the discharge pipe 110 with a funnel shape whose outer circumferential surface is in contact with the inner wall of the pipe and is connected to one end of the discharge pipe 110. The foreign matter is not disturbed by the air injected through the air pipe 120, And sucks the foreign matter through the pipe 110 so as to be efficiently discharged to the outside. In this embodiment, since the air-lifting device can move freely in depth in the tub, the outer region of the funnel-shaped suction pipe 130 can be made of rubber to prevent the movement of the fine particles.
