Abstract
The invention relates to discs of a disc type centrifuge, each comprising a disc body, a feeding hole and a rib, wherein the disc body is a ripple shape along the circumferential direction, and a straight line or helical line along the height direction, the feeding hole or the rib is arranged at the curved position of the disc. The feeding hole and the rib are arranged in interval along the circumference direction. The discs are coaxially overlapped, and the space is determined by the height of the rib. The space formed between the discs is also a ripple shape. The ripple shaped space recessed towards the axis side of the taper disc is a light phase channel, and the ripple shaped space projecting outwards is a heavy phase channel. The discs have the advantages that the ripple shaped taper disc respectively provides the dispersion phase and the continuous phase with flow channels, so that the mutual influence of two-phase flow is reduced, and the separation efficiency of the disc type centrifuge can be improved.
Description
Technical field
The present invention relates to the centrifugal separator field, refer in particular to a kind of centrifugal separator disk plate.
Background technology
Video disc is the critical piece of disc-type centrifugal separator, forms settlement space or passage between video disc.It mainly acts on is (1) basis " shallow pool principle ", reduces the particles settling distance, and (2) utilize cone shape, self-cleaning sedimentation face, and promptly the precipitum on the sedimentation face moves away under action of centrifugal force voluntarily.The mobile adverse current that is mainly of continuous phase and decentralized photo between video disc.Existing video disc all is simple taper seat, as US2007/0270298A1, and US2007/0066476A1, US2004/0023783A1, ZL89107941, ZL88107069, or the like.Because video disc spacing very little (0.3-3mm), flowing of continuous phase is very big to the mobile influence of decentralized photo, thereby influences separation process.
Summary of the invention
The purpose of this invention is to provide a kind of centrifugal separator disk plate, reduce the influence that continuous phase flows decentralized photo is flowed, with the separative efficiency of further raising disc-type centrifugal separator.
For achieving the above object, technical scheme of the present invention is, the taper video disc of centrifuge is designed to corrugated taper video disc.Space between the corrugated taper video disc also is corrugated.To the recessed corrugated space of taper video disc axis side is light phase passage, and outwards outstanding corrugated space is a heavy phase channels.Like this, corrugated taper video disc provides flow channel respectively for decentralized photo and continuous phase, reduces influencing each other of two-phase flow, thereby improves separation process.
Wherein the full cone angle of corrugated taper video disc is 70-100 °.
The ripple of corrugated taper video disc is sine curve or cosine curve.Wave number is 16-32.Wave amplitude is the inboard outside diameter of 0.01-0.02 taper video disc doubly.
The form of ripple on the conical surface is straight line, and it is parallel with cone element, or is the helix of the conical surface, and its pitch is the inboard outside diameter of 6-12 taper video disc doubly.
The zone of ripple on the conical surface be from taper video disc small end end face to from the inboard outside diameter of the taper video disc of 0.1 times of large end face, promptly at big end end face in the zone of the taper video disc inboard of 0.1 times of large end face outside diameter, ripple not being set.
The diameter of the charging hole of corrugated taper video disc is the inboard outside diameter of 0.03-0.06 taper video disc doubly, and the quantity of charging hole is 8-16.
The height of the rib of corrugated taper video disc is 0.3-3mm.Little person is used for liquid liquid and separates, and big person is used for Separation of Solid and Liquid.The quantity of rib is 8-16.
Advantage of the present invention: reduce the influence that continuous phase flows decentralized photo is flowed, separative efficiency with further raising disc-type centrifugal separator, and convoluted disc helps the rotation acceleration of material, shorten material and reach the required time of rated speed, can improve the production capacity of centrifugal separator like this.

The specific embodiment
Introduce embodiments of the invention below in conjunction with accompanying drawing.
The centrifugal separator disk plate that present embodiment provides is formed as Fig. 1, Fig. 2 and shown in Figure 3.It comprises video disc body (1), several charging holes (2) and several ribs (3) this video disc, wherein the video disc body along the circumferential direction is corrugated, along short transverse is straight line or helix, but is holding end face in the zone of the taper video disc inboard of 0.1 times of large end face outside diameter ripple not being set greatly.Recess is provided with charging hole (2) or rib (3) in video disc.Charging hole (2) and rib (3) are in the alternate setting of circumferencial direction.
Wherein the full cone angle of corrugated taper video disc is 80 °.
The ripple of corrugated taper video disc is a sine curve, and wave number is 16-32, and wave amplitude is the inboard outside diameter of 0.01-0.02 taper video disc doubly.
The form of ripple on the conical surface is straight line, and it is parallel with cone element, and its pitch is the inboard outside diameter of 6-12 taper video disc doubly.
The zone of ripple on the conical surface is to from the inboard outside diameter of the taper video disc of 0.1 times of large end face from taper video disc small end end face.
The charging hole quantity of corrugated taper video disc is 8-16, and diameter is identical, and its diameter is the inboard outside diameter of 0.03-0.06 taper video disc doubly.
The height of the rib of corrugated taper video disc is 0.3-3mm.Little person is used for liquid liquid and separates, and big person is used for Separation of Solid and Liquid.The quantity of rib is 8-16.
As shown in Figure 4 and Figure 5, video disc is coaxial to stack, and its spacing is by the height decision of rib.The space that forms between video disc also is corrugated.To the recessed corrugated space of taper video disc axis side is light phase passage, and outwards outstanding corrugated space is a heavy phase channels.Like this, corrugated taper video disc provides flow channel respectively for decentralized photo and continuous phase, reduces influencing each other of two-phase flow.These passages extend near charging hole, have not down just had again.To this position, heavy phase has occupied whole space, and light phase can not continue down, can only up flow, and discharges from taper video disc small end.Heavy phase overcomes channel resistance and throws away video disc under centrifugal action.
