Description

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 folds of the vortex tube 3. 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 solid separation, the solid material 4 is generated even if the solid separation is as 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 are accumulated at the lower tip portion of the taper, and the tip portion forming the bottom often causes blockage. .

[0007]

DISCLOSURE OF THE INVENTION The present invention overcomes the drawbacks of the conventional liquid cyclone apparatus as described above and, even when used in water and sewerage, does not cause blockage at the bottom of the vortex cylinder 3 for water and sewer. It is intended to provide a liquid cyclone device.

[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 is formed into a cylindrical shape, and a hydrocyclone for water and water is provided by arranging a resistance body against the water flow in the lower part thereof.

[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 a smaller chance of colliding 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
The reason is that they are made to accumulate.

[0013]

[Embodiment 1] In Embodiment 1, as the resistance object 6, a plurality of pillars in the same direction as the cylindrical direction are arranged as shown in FIG.

However, in order to prevent the solid substance 4 made of an organic substance having a slender shape, such as fibers or hairs, from winding around the pillar such as the resistance body 6 and dropping downward, the pillar is shown in FIG. ), The taper is designed to taper downward, and the drop is promoted.

[0015]

Second Embodiment In a second embodiment, as shown in FIG. 4 as the resistance body 6, a plurality of plates are provided from the inner wall of the vortex cylinder 3 along a water vortex flow direction at a portion whose transverse cross section is close to the inner wall, and A configuration is adopted in which a tip end portion and a portion close to the tip end have a curved shape toward the center of the cylinder.

In this case, the solid substance 4 in the vortex collides with the curved plate, and inevitably loses kinetic energy.
While falling downward, the grain itself is continuous with the peripheral wall of the movement, so that the organic substance having a long and narrow shape such as fibers and bristles does not wind around the plate.

[0017]

[Third Embodiment] A third embodiment shows a structure in which a plate is continuously abutted from the peripheral wall of the vortex cylinder 3 to the inside as a resistance object 6 in a mountain shape.

Also in this case, as in the case of the second embodiment, the solid substance 4 collides with the plate, loses kinetic energy, decreases, and falls downward. It does not wind around the board.

[0019]

In the present invention having the above-mentioned structure, not only ordinary earth and sand but of course organic substances having long and slender shapes 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 is extremely simple in 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.
