2 Description of Structure
2.1 Structure of Complete Separator
Structural components of disk-type centrifuge:
1. Charge and Discharge Device
2. Drum
3. Water Distribution Piping
4. Vertical shafting
5. Horizontal shafting
6. Speed measurement equipment
7. Brake
8. Motor
9. Rack
The right figure is for reference only, please prevail in kind.
Charge & Discharge Device: the device provides a channel to charge and discharge materials, including material charge and discharge.
Drum: the main place for the separation of materials.
Water Distribution Piping: provides sealing, opening water entering the channel in the drum body.
Drive Mechanism: The start of separator is friction start. The motor drives the gear pair through friction clutch, and then transfers to the vertical shafting to
drive the drum running. The friction clutch ensures the start-up process of the separator relatively stableand the acceleration relatively uniform, to prevent the motor and gear pair overloaded. In order to reduce the buffer seat wear and reduce the effect of the drum vibration on the whole equipment,
the buffer seat uses elastic supporting structure.
Speed measurement equipment: check the separator for normal operating state, the speed of separator is displayed by the counter in RPM. In normal operation.
2.2.1 Structure
The drum is the most important components of separator, as shown in the figure, the drum
body is fixed together with drum cover by main lock ring and equipped with the distributor and
the disk plate set. The top of drum cover and the centrifugal pump cover form a light-phase
pump chamber. The drum body is also equipped with piston and small valve structure inside,
and the drum and piton bottom form the sealing water chamber.
2.2.2 The function of separation
The flow of the liquid in the drum:
Materials enter the distributor from the upper feed inlet and through the feeding tube and are
distributed to the discs set for separation, the solid particles move along the disc and towards
the drum wall. During deslagging, the sludge is discharged from the sludge outlet; the
clear-liquid-phase enters the clear-liquid-phase pump chamber through the clear-liquid-phase
movement along the disk around the drum center and discharged out by the clear-liquid-phase
centripetal pump from the clear-liquid-phase outlet.
2.2.3 Function of residue removal
Normal separation:
The valve (1) is opened, the bottom of the piston (a) fill up with water, and due to the effect of
centrifugal force, the water at the bottom of the piston produces very high hydraulic pressure
F2 on the piston, which is higher than the hydraulic pressure F1 produced by the substances in
the inner cavity of the drum, the piston thus is driven to push against the seal ring (nylon) (b),
and it is ensured that the process of separation is carried out under the conditions in which the
inner cavity of the drum is airtight. The valve core (c) ensures that the nylon valve (d) doesn’t
leak by the centrifugal force F generated by itself. As the feed valve is opened, the separation
liquid continuously enters the drum for separating, and thus the solid particles are separated
from the separating liquid, and accumulated on the drum wall while the clear liquid phase is
discharged from the centripetal pump.
3 Installation
Caution: The separator with drum shall not be transported or hoisted in the installing
process; otherwise, it may cause damage to the bearings and vertical shaft.
When installing the separator, a sufficient space should be left to facilitate the repair and
maintenance of separator. The separator base can be of steel structure or of poured concrete,
but both should be solid and firm with smooth surface to minimize the interference from the
vibration of other machines.
When fixing the separator onto the foundation in place, the rubber damper pads should be
fitted under and above each foot of the separator, and then tighten the nuts.
All connections with the separator must be soft connected.
The pressure required by the separator operating water is 0.25-0.35MPa, and the operating
water must be connected with hoses to isolate the separator from the vibration of external
piping and to be easy to do maintenance work.
As the separator is installed and fixed, an attention should be paid to the motor for requirement
of electric system and the direction of rotation.
The residue outlet piping of the separator should be unblocked, to avoid the residue injected
back into the separator due to outlet blocked during residue removing.
