The specific embodiment

In order to make those skilled in the art person understand the utility model scheme better, and above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, the utility model is described in further detail below in conjunction with drawings and Examples.

See also shown in Fig. 1～4, be the utility model stereogram, assembled sectional view, A-A line cutaway view, B-B line cutaway view; Wherein, form cylindric position 2A above in cylinder 1, its internal diameter down dwindles gradually towards the lower end of cylindric position 2A, form the first funnel-form position 2B, the also tapered second funnel-form position 2C when lower end of this funnel-form position 2B forms an internal diameter than Datong District again, above-mentioned cylindric position 2A, first, second funnel-

form position

2B, 2C cooperate formation one vortex separation chamber 2; The top center of this vortex separation chamber 2 is vertically stretched the efferent duct cylindraceous portion 3 that is provided with to this cylindric position 2A, this efferent duct portion 3 links to each other with the tube connector 4 that upper end open is darted at cylinder 1 outer end, and these efferent duct portion 3 contiguous vortex separation chambers, 2 one ends are provided with an openend 3A simultaneously; The lower end of cylinder 1 is provided with a recovery cylinder 5, can be fixing or screw lock between this recovery cylinder 5 and the cylinder 1 and is equipped with.

Wherein, this cylinder 1 offers on one to expand towards this cylindric position 2A and narrow down is blown into mouthfuls 6, can be del, pouring drips shape or trapezoidal, wherein del can be provided with and be illustrated in figure 4 as the chamfer triangle or be illustrated in figure 6 as down forms such as isosceles triangle; It all be circular-arc that its various forms are blown into mouthfuls 6 joint, corner, generation sinuous flow when being blown into to reduce machinery oil, the smooth stability in the time of can reaching elevating mechanism oil and be blown into; In addition, as shown in Figure 4, be blown into mouthfuls 6 and the outer tube wall of efferent duct portion 3 between have a gap 6C, making this be blown into mouthful 6 machinery oil that are blown into can directly not collide with the outer tube wall of efferent duct portion 3, prevent the sinuous flow taken place because of colliding, and avoid also promptly being discharged away without separating by being blown into mouthful 6 machinery oil that are blown into, and further cause machine to be blocked and damage by the metal fragment 11 of machinery oil; In addition, cylinder 1 side and can be provided with a tube connector 7, its be blown into mouth 6 and be connected.

The utility model course of work is described as follows:

As shown in Figure 5, contain the cutting wet goods machinery oil of metal fragment from working machine 9 absorption, machinery oil delivered to above-mentioned tube connector 7 by pump 8, and with machinery oil by very high flowing velocity from being blown into mouthfuls 6 cylindric position 2A that are blown into vortex separation chamber 2; As Fig. 2, shown in Figure 3, shown in arrow the figure, can in cylindric position 2A, rotate from being blown into mouthful 6 machinery oil that are blown into; At this moment, the metal fragment 11 in the machinery oil just moves to the perisporium place of cylindric position 2A by the centrifugal force that rotation the time is produced, and down dropped by gravity effect and is deposited on recovery cylinder 5.

Connect describedly, as shown in Figure 4, the machinery oil of containing metal chip 11 just can not flow into the set efferent duct portion 3 in 2 upper ends, vortex separation chamber, flows out from tube connector 4 again; Thus, the machinery oil that flows out from tube connector 4 just can flow into working machine 9 circulations and re-uses; Wherein, between tube connector 4 and working machine 9, an after-filter 10 can be set again, in order to filter the machinery oil of recirculation, to obtain preferable recovery circulation machinery oil.

Wherein, expand on this that narrow down to be blown into mouthfuls 6 be to be tangential direction with this formed flow channel space in 2 upper ends, vortex separation chamber (also being cylindric position 2A) to offer formation, shown in tangent line L among Fig. 3; When machinery oil flow into vortex separation chamber 2 from being blown into mouth 6, because this is blown into mouth 6 and presents the expansion narrow form that is provided with down, therefore, it is narrow under the last expansion that to be blown into the machinery oil speed that mouthful 6 bottoms are blown into also faster than the machinery oil speed that the top was blown into, the swirl shape velocity ratio top that makes the bottom of cylindric position 2A form also wants fast, can steadily be imported to 2A bottom, cylindric position with the liquid that drives position, 2A top, cylindric position, and because this first funnel-form position 2B is the design of bore convergent form, make machinery oil can form the vortex sheet flow phenomenon by being blown into this first funnel-form position 2B that flows through after mouth 6 is blown into, and unlikely generation sinuous flow phenomenon.Therefore, see through above-mentioned described going up and expand the narrow down setting that is blown into mouthful 6 and first funnel-form position 2B, with the state that makes that the machinery oil that is blown into this vortex separation chamber 2 can keep stably stratified flow to descend, to keep very high centrifugal force.

Wherein, during the formed vortex of first funnel-form position 2B separated flow to the second funnel-form position 2C, also can further produce the effect that the layering vortex separates, make that atomic little metal fragment 11 can reach separating effect more really in the machinery oil, and when being full of machinery oil in the whole vortex separation chamber 2, machinery oil after having separated is adverse current and via the set openend 3A output in efferent duct portion 3 lower ends up, at this moment, from lower to upper in the machinery oil of adverse current, because 2B lower end, the relative aperture first funnel-form position, second funnel-form position 2C upper end bore is bigger, therefore will there be the part machinery oil can be by block in bore place, second funnel-form position 2C upper end, as shown in Figure 2, so further reach the effect of preferable separating metal chip 11.Wherein,, only form the first funnel-form position 2B, equally also can obtain good separating effect even without forming the second funnel-form position 2C.

After the metal fragment in the machinery oil 11 was separated, comparatively clean machinery oil can be exported to tube connector 4 by the 3 set openend 3A of efferent duct portion, delivered to after-filter 10 again to filter again, reclaimed machinery oil to obtain preferable circulation.

What remark additionally is that described centrifugal separating device also can be used for water tower, tank etc. and adheres to easily in the appliance arrangement of piling up impurity.

The utlity model has following beneficial effect:

Be blown into mouthful 6 upward expansions that have narrow form down, make and be blown into mouthful 6 tops, the machinery oil flow velocity that the bottom was blown into is that the top is slower, the bottom is very fast, the vortex that causes at cylindric position 2A separates whereby, it is faster than the flowing velocity on upper strata to form lower floor, and drive the upper strata machinery oil with the vortex that the lower floor machinery oil forms and slowly steadily down become to falling, to prevent the generation of sinuous flow, make metal fragment 11 with the centrifugal force of high velocity stream to 2A perisporium place, cylindric position, metal fragment 11 is matched to the gravity effect of deposit, reach high centrifugal force, and atomic little metal fragment 11 in the machinery oil is separated by centrifugal force, fall into again in the recovery cylinder 5, like this, make the maintaining operation of work mechanism more simple and convenient and quick.

The above; it only is the preferable specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement, all should be encompassed in protection domain of the present utility model in.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
