Abstract

The utility model discloses a kind of centrifuge sliding plunger, including：Discoid diapire；And side wall, wherein, the side wall integratedly combines the diapire on the periphery of the diapire and extends so as to form inverted interior frustum obliquely from the periphery of the diapire so that the side wall is from its bottom to top in the gesture for gradually extending out.This utility model has the gap that can reduce between sliding plunger and screen cloth, so as to improve the exclusion efficiency of filtering residue, and then improves the beneficial effect of separation efficiency.

Description

A kind of centrifuge sliding plunger

Technical field

This utility model is related to a kind of sliding plunger, more particularly, to a kind of centrifuge sliding plunger.

Background technology

Centrifuge is to utilize centrifugal force, separates the machine of each component in mixture of the liquid with solid particle or liquid with liquid Tool.Centrifuge is mainly used in separating the solid particle in suspension and liquid, or by two kinds of density differences in emulsion, and mutually Immiscible liquid separates (butter is for example isolated from milk)；It can also be used for excluding the liquid in wet solid, for example, use Washing machine dries wet clothes；The admixture of gas of the special also separable different densities of hypervelocity channel separator；It is close using difference The characteristics of sedimentation velocity is different in a liquid, some sedimentation centrifuges can also be to solid particle by close for the solid particle of degree or granularity Degree or granularity are classified.

In the course of the work, suspension is added in the conical cloth bucket being mounted on pusher disk centrifuge by charge pipe, Between centrifugal action low suspension Jing pushers disk and cloth bucket, space is thrown on screen cloth, here liquid Jing screen clothes gap and turn On drum, aperture is thrown away outside rotary drum, and stream is to mother solution catcher, and solid phase forms filter cake layer on screen cloth, because pusher disk it is constantly reciprocal The filter cake layer of motion formation is axially constantly pushed forward shifting along rotary drum, and is finally released rotary drum to front housing by sliding plunger Discharging opening.

As the high speed rotation of centrifugal rotor can drive its base to produce vibrations, centrifuge sliding plunger is easily caused with sieve Gap between net is excessive, so as to cause the release of filtering residue not thorough, affects production, reduces separation efficiency.

Utility model content

For weak point present in above-mentioned technology, the purpose of this utility model is to provide a kind of centrifuge slip and lives Plug, which can reduce the gap between sliding plunger and screen cloth, so as to improve the exclusion efficiency of filtering residue, and then improve separation effect Rate.

In order to realize according to these purposes of the present utility model and other advantages, there is provided a kind of centrifuge sliding plunger, Including：

Discoid diapire；And side wall,

Wherein, the side wall is integratedly with reference to the diapire and oblique from the periphery of the diapire on the periphery of the diapire It is upper to extend so as to form inverted interior frustum so that the side wall is from its bottom to top in the gesture for gradually extending out.

Preferably, the middle part of the diapire is swelled upwards so as to form frustum.

Preferably, boss is integratedly combined with the frustum, is provided with installing hole, institute the center vertical of the diapire Installing hole is stated through the frustum and boss.

Preferably, the taper of the frustum is α, then have α=90 °～120 °.

Preferably, the taper of the interior frustum is β, then have β=50 °～65 °.

Preferably, the top outer of the side wall is integrally provided with a circle lip, and the lateral surface of the lip is vertical Arrange, the root of the lip is provided with fillet.

Compared with prior art, its advantage is this utility model：Which can reduce between sliding plunger and screen cloth Gap, so as to improve the exclusion efficiency of filtering residue, and then improves separation efficiency.

Part is embodied by other advantages of the present utility model, target and feature by description below, and part will also pass through Research of the present utility model and practice are understood by the person skilled in the art.

Description of the drawings

Fig. 1 is the structural representation according to centrifuge sliding plunger in an embodiment described in the utility model.

Specific embodiment

Below in conjunction with the accompanying drawings this utility model is described in further detail, of the present utility model aforementioned and other mesh , feature, aspect and advantage will be apparent from, to make those skilled in the art can be real according to this with reference to specification word Apply.

Referring to Fig. 1, centrifuge sliding plunger 100 includes：

Discoid diapire 110；And side wall 120,

Wherein, side wall 120 integratedly combines the diapire 110 and the periphery from the diapire 110 on the periphery of diapire 110 Extend so as to form inverted interior frustum S1 obliquely so that side wall 120 is from its bottom to top in the gesture for gradually extending out.

With reference to Fig. 1, the middle part of diapire 110 is swelled upwards so as to form frustum S2, and boss is integratedly combined with frustum S2 112, it is provided with installing hole 112 center vertical of diapire 110, installing hole 112 runs through frustum S2 and boss 112.In an embodiment party In formula, the taper of frustum S2 is α, then have α=90 °～120 °.In one embodiment, the taper of interior frustum S2 is β, then have β =50 °～65 °.

With reference to Fig. 1, side wall 120 includes inclined wall 121 and the lip 122 positioned at the top of side wall 120, outside lip 122 Side vertical is arranged, and the root of lip 122 is provided with fillet.In one embodiment, the height of side wall 120 is H, boss 112 Highly it is h, the opening diameter at the top of side wall 120 is D, a diameter of d of diapire, then have H=160～175mm, h=60～80mm, D=610～710mm, d=510～540mm.

Number of devices described herein and treatment scale are for simplifying explanation of the present utility model.To this utility model Application, modifications and variations will be readily apparent to persons skilled in the art.

As described above, according to this utility model, which can reduce the gap between sliding plunger and screen cloth, so as to improve filter The exclusion efficiency of slag, and then improve separation efficiency.

Although embodiment of the present utility model is disclosed as above, which is not limited in institute in description and embodiment Row are used, and it can be applied to various suitable fields of the present utility model completely, for those skilled in the art, can Other modification is realized easily, therefore under the general concept limited without departing substantially from claim and equivalency range, this practicality It is new to be not limited to specific details and shown here as the legend with description.
