Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid cyclone device for sewage and sewage for separating solid substances in sewage and sewage from a liquid.

[0002]

2. Description of the Related Art As shown in FIG. 1, a conventional hydrocyclone device comprises a supply cylinder 1, a discharge cylinder 2 located above the supply cylinder 1, and a vortex cylinder 3 located below the supply cylinder 1. The solid substance 4 forms a vortex flow in the transverse section in the vortex tube 3 as well as in the supply tube 1 and circulates in the longitudinal section, but at this time, it moves by colliding with the inner fold of the vortex tube Energy is lost / reduced, and it falls to the bunker 5 below.

In the conventional liquid cyclone device, as shown in FIG. 1, the vortex cylinder 3 is designed so that its peripheral wall has a truncated cone shape.

This is because when the solid substance 4 circulates in the vortex cylinder 3, more machines collide with the peripheral wall of the vortex cylinder 3 and the chances of dropping the solid substance 4 downward are increased.

By the way, the conventional liquid cyclone device originates from the solid separation of the mined material in the mine. In such a solid separation, even if the solid separation 4 has the structure shown in FIG. Since it was made of rock, sand, etc., the lower tip portion did not accumulate at the bottom of the tapered vortex tube 3 and the tip portion was not blocked.

However, when the liquid cyclone device shown in FIG. 1 is used for solid separation in water and sewage, not only earth and sand but also organic substances having elongated shapes such as fibers and hairs exist in the water, In the truncated cone-shaped vortex cylinder 3 shown in FIG. 1, organic substances having these elongated shapes accumulate at the lower tip portion of the taper, and the tip portion forming the bottom often causes blockage. .

[0007]

SUMMARY OF THE INVENTION The present invention overcomes the drawbacks of the conventional liquid cyclone device as described above, does not cause blockage at the bottom of the vortex cylinder 3 even when used in water and sewer , and is solid. An object of the present invention is to provide a hydrocyclone for water and sewage that can maintain the effect of separation .

[0008]

In order to solve the above problems, the structure of the present invention has a liquid cyclone having a supply cylinder, a discharge cylinder located above the supply cylinder, and a vortex cylinder located below the supply cylinder. In the vessel, the vortex cylinder should be cylindrical and the lower part should have multiple columns with a tapered shape.
It consists of a hydrocyclone for water and sewage by arranging a resistance body against the water flow by and.

[0009]

FIG. 2 shows a hydrocyclone for water and sewage according to the present invention.

In FIG. 2, the drawing of the vortex cylinder 3 is not a truncated cone shape as in the conventional case, but a cylindrical shape.

However, if the solid substance 4 in the liquid collides with the wall surface of the vortex cylinder only by simply circulating it through the cylindrical vortex cylinder 3, the solid substance 4 has less chance to collide with the wall surface of the truncated cone. Loses its kinetic energy, and there is little chance of falling down.

Therefore, in the present invention, the resistance body 6 against the water flow is provided below the cylindrical vortex cylinder 3, and the solid substance 4 in the water flow collides with the resistance body 6 to lose kinetic energy. Decrease and drop down, bunker 5
However, the resistance object 6 is
Then, as shown in Fig. 3 (a) and (b), follow the downward direction.
Multiple cylindrical resistance objects that are tapered
It

As a result , long and thin fibers or hairs can be obtained.
The solid substance 4 made of organic matter having a shape is a resistance object 6 or the like.
Even if it wraps around the pillar, it will fall downward naturally with the water flow.
Will be urged to do so.

[0014]

EXAMPLE FIGS. 3 (a) and 3 (b) show a resistive object of the present invention.
6 shows an example, and shows a gradual tapering tendency in the upper part.
Shown below is an example of the case in which the shape is sharp at the bottom.
You. With such a shape, the above-mentioned action occurs.
Needless to say. The configuration of the present application is as shown in FIG.
The shapes are not limited to those shown in (a) and (b).
Other shapes (for example, a cross section with the lower part as the apex)
There is also an equilateral triangle case).

[0015]

In the present invention having the above-mentioned structure, not only ordinary earth and sand but of course, organic substances having a slender shape such as organic matter, fibers and hairs also fall downward due to collision with the resistance body 6. At the same time, since the bottom of the vortex cylinder has a cylindrical shape, the vortex cylinder 3 is not blocked by these elongated organic substances, and the solid-liquid separation of sewage is smoothly promoted.

As described above, the present invention has an extremely simple structure, but can sufficiently overcome the obstacles in solid-liquid separation of sewage and sewage as compared with the conventional liquid cyclone device, and is therefore of great value.
