Description

DETAILED DESCRIPTION OF THE INVENTION a. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a muddy water treatment device capable of high-speed treatment.

b. 2. Description of the Related Art In civil engineering work on soft ground, it is necessary to quickly treat mud water. In addition, it is difficult to treat mud water such as sludge during the landfill work on the coast.

Various muddy water treatment devices are used to perform such muddy water treatment. Usually, a method of removing water by compression or drying with hot air is common.

c. DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in the processing work of sludge and the like, it is necessary to promptly process the muddy water pumped up by the pump, and thus the processing work is required to be speeded up.

An object of the present invention is to solve the above problems and to provide a muddy water treatment device capable of treating muddy water at high speed.

d. Means for Solving the Problems In order to solve the above problems, the present invention provides a rotating shaft provided in a case and an axis supported by the rotating shaft,
A multi-layered treatment tank in which a plurality of concentric overlayers are formed on the peripheral surface, a muddy water supply pipe that is provided concentrically with the rotating shaft, and opens at the innermost part of the treating tank, and the rotating shaft is at a predetermined angle A slanted support is provided, the upper surface of the processing tank is opened, and an overlayer of the outer tank peripheral surface is more densely formed with respect to the inner tank peripheral surface, and the mud water supplied into the processing tank is centrifuged. Dispersion is performed by force, and moisture is discharged from the overlayer and solid matter is discharged from the upper opening.

e. Function The muddy water pumped up by the pump is supplied into the multi-layer treatment tank through the muddy water supply pipe. The multi-layer processing tank is driven to rotate at high speed to dehydrate the water content of the muddy water. The muddy water that has passed through the inner overlayer is dehydrated by the outer overlayer. The solid matter in the muddy water dewatered in the inner tank and the outer tank is dispersed by the centrifugal force accompanying the rotation of the multi-layer processing tank, and jetted from the upper opening. In this way, muddy water is sequentially fed from the muddy water supply pipe to perform high-speed dehydration processing.

f. Embodiment Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

In FIG. 1, reference numeral 1 is a muddy water treatment apparatus main body that is mounted on a support base 2 at a predetermined angle. This processing device body 1
Is a rotary shaft 4 which is inclined at a predetermined angle θ and penetrates through the case 3, and a drive device 5 for rotationally driving the rotary shaft 4.
A multi-layered over-layer 7 supported axially on the rotary shaft 4 and having a plurality of concentric over-layers 6 formed on the circumferential surface, and a multi-layered over-layer 7 concentrically provided on the rotary shaft 4. 7 is provided with a muddy water supply pipe 8 opened to the innermost tank.

The rotating shaft 4 is rotatably supported in the middle thereof by a bearing box 9 provided in the case 3, and its tip is rotatably fitted to a concentric shaft portion 8a in the muddy water supply pipe 8 via a bearing 10. Have been combined. The muddy water supply pipe 8 forms a muddy water passage 8b around a shaft portion 8a coupled to the rotary shaft 4, and is attached to the lid portion 3a of the case 3 in the middle thereof.

The multi-layered over tank 7 is a combination of two basket-shaped over tanks 11 each having an open upper surface, which are concentric with each other, and each of which is formed so that its upper surface side is widened toward the end. The multi-layered over tank 11 is supported by the muddy water supply pipe 8 via a bearing 12 on the upper opening side. As for the peripheral surface overlayer 6 of these overtanks 11, the inner tank 11 ₁ is formed in a mesh layer, and the outer tank 11 ₂ is formed in a finer overlayer 6 using a cloth or the like.

In case 3 above, a solid material discharge port is provided along with a muddy water discharge port 13.
14 are provided.

The case 3 is provided with an air outlet 15 for blowing air such as hot air into the openings of the inner tank 11 ₁ and the outer tank 11 ₂ .
The air outlet port 15 is connected to a compressor (not shown) or the like, and a heating coil or the like is arranged in the middle of the pipeline.

According to the above structure, the rotation shaft 4 is driven by the operation of the driving device 5.
Is driven, and the multi-layered excess tank 7 rotates at high speed.

On the other hand, muddy water such as sludge drawn up by the operation of the pump is supplied from the muddy water supply pipe 8 to the innermost tank 11 ₁ of the multi-layered over tank 7. The muddy water supplied to the inner tank 11 ₁ of the multi-layered over tank 7 is centrifuged to allow the water to pass through the over layer 6 and the outer tank 11 ₂
Is umbrella, the residue is discharged ejected from the upper opening of the inner tank 11 ₁ by centrifugal force.

The water was umbrella outer tub 11 ₂ is the bulk, leaving a fine solid particle by excessive layers 6 is drained from the drain outlet 13. The residue remaining in the over-layer 6 is discharged ejected from the upper opening of the outer tub 11 ₂ by centrifugal force.

The residual solid matter ejected from the upper surface openings of the inner tank 11 ₁ and the outer tank 11 ₂ is discharged from the discharge port 14 to the outside.

g. Effects of the Invention As described above, according to the muddy water treatment device of the present invention,
Since water and solids are separated by centrifugal force, muddy water such as sludge can be separated at high speed.
