Abstract

In order to improve the water quality of dams, the air pumping pipe water quality improvement system installed in the water is installed and operated in various domestic dams. This water quality improver has a cylindrical long air pumping pipe with a central weight at the bottom and a mouthpiece at the top so that it stands upright in the water and the compressed air from the external air compressor is injected into the air chamber of the air pumping pipe through a hose. When the air is injected into the air chamber, the air is raised to the surface along the air pumping pipe at a time (continuously), and the water at the bottom of the dam is brought to the surface to circulate the water around the pumping pipe.

In this process, oxygen is supplied, water temperature difference according to water depth is reduced, and water quality is improved by inducing changes in water environment. However, in order to increase the water quality improvement effect, the pumping pipe should be erected upright and the bottom layer of water pumped on the water surface should be diffused and mixed far. For this purpose, it uses sturdy float installation frame and installs diffuser plate between pumping pipes to increase stable upright and diffusion effect.

Description

Air Lifting Tube with Deflector and Attachment

Conventional techniques for improving the water quality of the dam include an air pumping pipe installed upright in the water of the dam, and the air pumping pipe has a constant length of the pipe and an adjustable pump to adjust the length of the pipe according to the change of the dam level. There is this.

In the case of a fixed length pipe, a buckle corresponding to the buoyancy necessary for standing up underwater is attached to the upper pumping pipe.

However, the adjustable pump controls the length of the air pump and attaches the float support (a) to the top of the air pump as shown in Figure 2 and connects the float (3) with the appropriate buoyancy to the water (b). In this way, the length of the pipe is controlled by overlapping or exiting the pipe as the water level changes. The support (a) of the float is attached symmetrically to the discharge port of the pump or at equal intervals on the circumference so that the center of buoyancy coincides with the upright axis of the pump. If you attach a float to the pump in this way, the horizontal diffusion effect of the water is insufficient, the support is bent or detached, and the float connection line is often broken.

At this time, the pump tube will be inclined and will not function properly.

The air pump draws up and circulates water from the bottom of the dam, providing oxygen and mixing water to improve water quality. Therefore, it is advisable to allow more water to circulate through large bodies of water. The amount of water to be circulated depends on the capacity of the pump, but the circulating water becomes wider when the low-level water flowing up to the surface is flowed far and horizontally.

The air pump upright method by the conventional support (a) occurs when the support is bent or detached, or when the float connection line (b) is broken, and the pump is inclined so that the pump is not stretched well. The ability is reduced.

Even in a normal upright state, low-rise water (water at the bottom of the dam) that has risen along the air pumping pipe to the surface of the water is low due to its low temperature, so it tends to go straight down rather than spread horizontally. Therefore, in order to solve these two problems, instead of the support, a structural float mounting frame (2) is used to attach a float and assembling the diffuser plate (3) together between the mounting frame and the air pumping pipe together, thereby increasing the specific gravity along the pump pipe. When this large cold water hits the diffuser plate and flows horizontally, it mixes with the warm water of the water surface, and the specific gravity becomes light and flows far horizontally.

In this way, it is a technical task of the present invention to make water pumps erect upright and to raise the water flow horizontally to increase the water quality improvement effect.

Instead of the upright and pump length adjustment method using the support (a), the float (3) and the connecting line (b) of the adjustable pump according to FIG. 2, external forces such as buoyancy of buoys, water flow waves, etc. It is to be assembled as shown in Fig. 1 by inserting the diffuser plate 4 between the installation frame and the pumping pipe 1 instead of the float installation frame 2 of a sturdy structure which does not deform the pressure of air and water coming from the is.

The float fitting frame 2 is made by welding the large circle 2-1 and the small circle 2-2 of FIG. 3 with a plurality of (3-4) connecting rods 2-3, and the large circle 2-1. There are a number of floats (3) attached to the small circle (2-2) is made to be the same as the inner diameter of the upper end of the pump pipe to the upper flange of the pump pipe together with the diffusion plate 4 as shown in Figs. Secure with bolts (2-4).

The diffuser plate (4) is made of a disc and drills holes in the center, such as the inner diameter of the pump, to allow air and water to pass through.

The pumping pipe is held upright by the chain (1-3) to the center (1-4) by the buoyancy force of the buoy (3) of the float installation frame (2), and the pipe that stretches according to the water level is connected ) Will be adjusted within the range without falling out.

In this configuration, when the compressed air is injected into the pump pipe chamber 1-2 through the hose 1-5 in the air compressor not shown in the configuration, the air rises along the pump pipe 1 and is released into the atmosphere and together with the air. The water that rises to the surface hits the diffuser plate like 4th and 4th, and flows horizontally without going down immediately.

Increasing the water quality improvement effect of the air pumping pipe installed in the dam is economical to improve the water quality, and by attaching it to the height-controlled air pumping pipe installed in the future, a great water quality improvement effect can be expected. It can also be applied to existing pumps and can be expected to develop more technologies related to water quality improvement.
