Abstract

A pressurizing centrifugal dehydrator for removing moisture according to the present disclosure includes: an inner basket into which slurry is introduced; an outer basket surrounding the inner basket; a blocking barrier disposed in the outer basket; and a gas supplying portion for supplying gas into the inner basket and/or the outer basket, wherein a dehydration product is positioned between an outer circumference of the blocking barrier and an inner side of the outer basket to maintain airtightness of the outer basket.

First claim

The invention claimed is:

1. A pressurizing centrifugal dehydrator for removing moisture, the pressurizing centrifugal dehydrator comprising:
an inner basket into which slurry is introduced;
an outer basket surrounding the inner basket;
a blocking barrier disposed in the outer basket; and
a gas supplying portion for supplying gas into at least one of the inner basket or the outer basket,
wherein a dehydration product is positioned between an outer circumference of the blocking barrier and an inner side of the outer basket to maintain airtightness of the outer basket, and
wherein the blocking barrier includes:
a blocking barrier rotating portion that is fixed to the outer basket and rotates together with the outer basket;
a blocking barrier fixing portion that is disposed inside the blocking barrier rotating portion and is fixed; and
a rotating-fixing connection portion disposed between the blocking barrier rotating portion and the blocking barrier fixing portion.

2. The pressurizing centrifugal dehydrator of claim 1 , wherein a gas supplying portion hole, through which the gas supplying portion penetrates, is formed in the blocking barrier.

3. The pressurizing centrifugal dehydrator of claim 1 , wherein a slurry supplying portion hole, through which a slurry supplying portion for supplying the slurry to the inner basket penetrates, is formed in the blocking barrier.

4. The pressurizing centrifugal dehydrator of claim 1 , wherein a washing water supplying portion hole, through which a washing water supplying portion for supplying washing water to the inner basket penetrates, is formed in the blocking barrier.

5. The pressurizing centrifugal dehydrator of claim 1 , wherein the dehydration product positioned between the outer circumference of the blocking barrier and the inner side of the outer basket is discharged due to a dehydration product pushed from the inside of the outer basket.

6. The pressurizing centrifugal dehydrator of claim 1 , wherein the dehydration product is continuously discharged by passing between the outer circumference of the blocking barrier and the inner side of the outer basket.

7. The pressurizing centrifugal dehydrator of claim 1 , wherein the rotating-fixing connection portion fixes the blocking barrier fixing portion while allowing rotation of the blocking barrier rotating portion.

8. The pressurizing centrifugal dehydrator of claim 1 , wherein an inclined portion is formed in the blocking barrier rotating portion.
