Abstract

PURPOSE: To enable dewatered raw material to be continuously taken out from either an upper end or a lower end of a rotating member by a method where the raw material is caused to move upward or downward at a side wall of the rotating member. CONSTITUTION: A rotating member 1 is held by bearings 8 and rotated through a V-pulley 10 and a shaft 9. Raw material 11 loaded from a feeding port 2 is equally divided on a rotating disk 7 arranged inside the rotating member 1, placed on belts 6 of a plurality of conveyors which can be filtered with a centrifugal force, the raw material is moved upward while it is being dewatered. Water is discharged out of the holes of the rotating member 1, the water flows down along an inside part of an outer cylinder 4 and is discharged out of a lower end of the cylinder. The raw material 11 dewatered by it moves away from an upper end of each of the conveyors 5 and is discharged out of a water discharging drain port 3 at the upper end of the rotating member 1.. Accordingly, a less friction is generated at the filtering surfaces during water discharging operation, a less clogged state occurs, the clogged state is removed under its own cleaning action with a centrifugal force when each of the belts reaches a rear surface therearound, so that a dewatering efficiency can be increased.

Description

Detailed Description of the Invention

[Industrial application field] For mining, pulverized coal dehydration treatment,
For crushing and quarrying, fine sand is dehydrated, sea sand is dehydrated and demineralized, and for civil engineering, sludge can be treated from solids containing not only water but also other liquids.

2. Description of the Related Art Conventionally, in this type, continuous dewatering is not possible only with a rotating body, or a screw conveyor is provided in the rotating body, and the raw materials are forcibly moved due to the speed difference between them, whereby continuous dewatering is performed. As a result, the filter surface was rubbed, causing abrasion and clogging.

SUMMARY OF THE INVENTION An object of the present invention is to provide an apparatus characterized in that continuous dehydration can be performed while easily moving a raw material without friction between a driving belt and a side wall. It is in.

SUMMARY OF THE INVENTION According to the present invention, a plurality of conveyors are provided on the side wall of a rotating body with a filterable belt, and the centrifugal force of the rotating body and the driving of the conveyor continuously dewater the raw material mainly containing water. Is about doing.

Since the raw material is moved by driving the belt in this apparatus, there is no friction with the filtration surface during dewatering and there is little clogging. Moreover, when the belt comes to the back surface, the self-cleaning action by the centrifugal force removes the clogging, and the dehydration efficiency can be improved.

[Brief description of drawings]

The drawings are sectional views and will be described with reference to the embodiments shown in the drawings. Reference numeral 1 denotes a rotating body, which is firmly held by a bearing 8, and the rotation of the drive source rotates the rotating body 1 through a V pulley 10 and a shaft 9. The raw material 11 charged from the charging port 2 is substantially evenly divided on the rotary disk 7 provided in the rotary body 1, is placed on the belt 6 by centrifugal force, and is moved upward while being dehydrated. Water is discharged from a hole provided in the rotating body 1, flows downward along the inside of the outer cylinder 4, and is taken out from the lower end. The dehydrated raw material 11 leaves the upper end of the conveyor 5 and is discharged from the drainage port 3 provided at the upper end of the rotating body 1.
