With reference to accompanying drawing, figure 1 illustrates a separator 10, comprise a cylindrical shell 12, it is bearing on member 14 and 16 and has an inlet tube 18 and an outlet 20.The fluid that contains particle, the water that for example contains sand and/or other solid particle, be introduced into and make it to enter shell forming a vortex implanted layer within it through inlet tube, this vortex implanted layer is thrown to the outside of layer by centrifugal action with particle, and the core of cleaning is discharged through outlet.At last, particle is collected in a deposition at the opposed end place of shell or precipitation chamber 22, and synchronism ground is therefrom discharged it or taken out through an excretory duct 24.

As shown in Figure 2, shell 12 is columned, and its end is by lid 26 and 28 sealings, and outlet is positioned at 26 the center covered and coaxial with shell.Also be that to be positioned at coaxially on the shell be one to limit the circular cylindrical wall or the tube 30 of vortex chamber, an end of wall is around outlet and by an annular endplate 34 sealings.One group separates part 35 and keeps the other end of tube coaxial with shell.For this purpose, being fixed on three of separating with angle on the outer faucal, this to separate part enough.Shell and tube form a double-walled construction, define an annular chamber 36a and an annular space 36b.The end of chamber 36a is by lid 26 and plate 34 sealing, and the other end is then by being fixed on the annular slab 38 on the shell 12 and being fixed on a superimposed panel 40 on the tube by the packing ring between plate or seal 42 sealings.

With reference to Fig. 3, the end that centers on the tube of outlet is provided with one group of elongate aperture shape or sealing shape inlet 44, and fluid can obliquely inject through this group inlet executes the chamber, whirlpool, so that fluid generation swirling motion.As shown in Figure 4, on the other end of tube or the downstream one group of plate that extends radially inwardly or fin 46 are installed, pipe 48 coaxial of their supportings with tube.The downstream edge of each fin 46 is provided with a sweep or flanging 50, the purpose that is used to be described further below.A plectane or dividing plate 52 with horizontal expansion portion of upstream edge supporting of fin is to provide one closely-spaced 54 between the inner surface of its circumferential edges and tube.It is 44 best to enter the mouth, but nonessential, has resilient flexible disgrace portion or the expansible slit described in my the unsettled U.S. Patent Application Serial 656,312 (on July 24th, 1967 submitted).

The pipe 56 that to be another in pipe 48 downstream supported coaxially by radial plate or fin 58 and shell 12 is shown in Fig. 2 and 5.End cap 28 has a sleeve part 60, and installing within it to slide and to be installed in the pipe is a tubular support 62 that has handle 64 and a deflecting plates or kick plate 66.Can vertically regulate tubular support as required, with the location deflecting plates.For this reason, the outer surface of sleeve part is processed with screw thread, to mesh with a tapped box nut 68, is out of shape thereby push an elastic material ring 70 and make it, and holds pressure tubular support is applied friction and liquid password protection.

Simultaneously with reference to Fig. 6, a fluid passage, for example a pipeline 72 or an analog connects the upstream extremity of annular space 36b and the inside of inlet tube 18.The end of this pipeline in inlet tube is provided with a Venturi tube or aspirating mechanism 74, comprises a cover plate 76, and its lateral edges is sealed on the inlet tube, and its openend towards fluid through the inlet tube travel direction.Like this, when fluid when inlet tube flows, just in cover plate, produce a negative pressure, and aspirate fluid through this pipeline.

Should be noted that inlet tube is to be connected on the shell 12, the fluid through the inlet tube input just roughly tangentially enters annular chamber 36a under pressure like this, and follows an eddy flow track, is schematically shown as a helix with band arrow 80 among Fig. 7.The lengthwise movement and in time pass the aperture or enter the mouth 44 in the 36a of chamber of this eddy flow fluid with the vorticla motion state of the centrifugal effect of a kind of tool.This just makes fluid form a helical form vortex implanted layer 82 against the inner surface of tube, the thickness of this helical form vortex implanted layer increases gradually and is obstructed slightly in vortex chamber internal cause frictional force when fluid is mobile downstream, is schematically shown as a helix of being with arrow 84.Layer 82 has a center or vortex part 86, and its counter motion still keeps identical direction of rotation simultaneously, is schematically shown as the helix of being with arrow 88.

Concerning this whizzer, above-mentioned vortex effect is intrinsic.Yet the core of implanted layer begins the combination that its heterodromous point but depends on Several Factors, comprises the shape and the volume of vortex chamber, the initial rotary speed of implanted layer, and this initial rotary speed depends on pressure reduction or conditions of similarity.

One of the purpose of this utility model is to limit this reversal point more accurately.This finishes by location deflecting plates or kick plate 66, the upstream face of this plate 66 is separated also this core of reflexed as the core that makes implanted layer with the circumferential section or the particle collecting region of this layer, thereby helps the output conversion direction of clean fluid towards device.This circumferential section that contains solid particle is followed the spiral trajectory that the helix by band arrow 88 is schematically shown and is slowly moved to the downstream, and passes the interval 54 between dividing plate 52 and the vortex chamber wall 30 at last.

The part of the implanted layer in kick plate 66 downstreams become because of the rotary speed of this layer descends exceed add static.Yet this part produces a center vortex that upstream moves again very slowly, shown in the helix of band arrow 90 among Fig. 7.To going back to the downstream part that this layer advanced in deflection, the mode of carrying out deflection is the inactive state of not disturbing within it to be produced and prevents to mix with clean core by the implanted layer of the upstream face institute reflexed of this plate this vortex by the downstream surface of kick plate.The diameter of kick plate is unimportant and can arrive variation in about 1/2nd the size range at about 1/4th of vortex chamber diameter.In any case but the diameter of this plate is less than the diameter of dividing plate.

Deposit cavity 22 is positioned at the part in shell vortex chamber 32 downstreams, and constitutes a precipitation chamber, and the fluid that contains many particles promptly is housed inside in it to deposit particle and after export 24 it is discharged in shell.For ease of the deposition of particle, wish that the fluid in the chamber is static as much as possible.For this reason, after fluid passes interval 54.Fin 46 is as any remaining swirling motion of dampening fluid.The motion of the fluid by fin combines with the deflection (this deflection is opposite with swirling motion on direction) that flanging 52 convection cells cause, and has just stopped all swirling motions of fluid, thereby obtains roughly static fluid state.

Like this, the other end of shell provides a deposit cavity, in order to hold isolated particle from fluid.Fluid injects vortex chamber by a series of inlets around outlet, and these inlets make fluid produce vorticla motion, thereby make it to move towards deposit cavity along a centrifugal helical trajectory, and produce an implanted layer of progressive additive towards downstream.In the middle of the two ends of vortex chamber is a circular kick plate 66, and it can vertically be regulated with respect to outlet, makes it to turn to towards outlet with the direction that changes implanted layer penetrale, and the lengthwise position of kick plate has been adjusted vortex and determined the scope of implanted layer thereupon.In the downstream of kick plate is a toroidal membrane, and it is positioned at the center of vortex chamber and its circumferential edges and vortex chamber spaced slightly opens, and the outermost portion of implanted layer promptly passes this interval.After fluid passed dividing plate, it ran into the fin of warp-wise location, and these fins have hindered any lasting inertia vorticla motion, so that fluid is static and impel solid particle to deposit.Make a part of fluid of therefrom isolating particle already pass the space between shell and the vortex chamber and enter inlet tube, produce a little negative pressure with downstream, thereby improve the efficient of device at dividing plate and fin by the aspirator in the inlet tube.

One oblate spheroid particle shell 240 is fixed on the far-end of shell 211, as shown in figure 13.This housing defines an inner pressurd vessel 241, receives particulate matter in order to the far-end from shell.One particle discharge line 244 is connected in particle shell and in its lower end one mounting flange 245 is arranged, in order to be connected with another unshowned pipeline, to export particulate matter from equipment.One group of extension 246 is fixed on the far-end of shell and therefrom extends into the inner pressurd vessel of particle shell to the end.One end plate 247 is to be installed on the extension with the far-end spaced relationship and to be approximately perpendicular to shell.

The equipment of in Figure 15, having represented another embodiment with reference number 310.Equipment 210 structurally is similar to equipment 110 described above and 210 substantially.Equipment 310 has a roughly columned shell 311, and it has a upper end 312 and a bottom 313.This shell has the last circular cylindrical interior surface 314 of a predetermined diameter, one is connected in surface 314 and the coaxial taper inner surface 315 from the centre of this surface tilt, with one be connected in surface 315 and constitute the following circular cylindrical interior surface 316 that the diameter of outer cover length remainder reduces, as shown in figure 15.One top circumferential flange 317 is installed in the upper part of shell, and a bottom circumferential flange 318 is installed in the end portion of shell.

As shown in figure 16, an inlet tube 320 is installed on the upper part 312 of shell 311 and with it and is communicated with.This inlet tube has a far-end mounting flange 321, contains grain flow body source (not shown) in order to what connect a band pressure.

On end plate 322, be fixed with an inner thread sleeve 327 coaxially with shell 311.Fluid outlet pipe with inner end 329 and male thread portion 330 328 and shell screw thread coaxially are installed in the sleeve 327, axially adjust doing in sleeve.One mounting flange, 331 screw threads for fastening are on the male thread portion of outlet and can be connected in a unshowned pipeline, in order to export fluid from equipment.One separation, constriction plate or dividing plate 332 are fixed on the inner end portion of outlet, and extend transverse to the inside of shell with one heart with the taper inner surface 315 of shell, as shown in figure 15.This dividing plate has one to be roughly hemispheric surperficially 333, and it faces the diameter that end plate and its diameter are substantially equal to the following circular cylindrical interior surface 316 of shell.Like this, dividing plate and taper inner surface define a constricted channel 334 that area is adjustable between them, as will be hereinafter with in greater detail.The dividing plate that extends transverse to the inside of shell is separated into a fluctuation chamber 335 between end plate 322 and dividing plate 332 with its inside, and the disengagement chamber 336 between the end portion 313 of dividing plate and shell.

One particle shell 240 has an inner pressurd vessel 341 and a circumference mounting flange 342, and is installed on the end portion 313 of shell 311, mounting flange 342 and lower circumference flange 318 engagements and fixing on the throne by suitable bolt and nut component 343.One particle discharge pipe 344 is installed on the housing and the close engagement of liquid with it, and has a far-end mounting flange 345 that is connected in a pipeline.As shown in figure 15, one group of extension 346 is fixed on the end portion 313 of shell and to the end and extends into inner pressurd vessel.One end plate 347 is fixed on the extension and to locate transverse to inner pressurd vessel with the shell spaced relationship, and is identical as first kind of form of equipment 110.

The fluid that contains particle is transfused to each equipment 110 respectively under pressure, 210 and 310 inlet tube 120,220 and 320, and therefrom tangentially entered respectively the fluctuation chamber 131,231 and 335, thereby in each equipment, produce a vortex implanted layer of following to be roughly the helical form running orbit, be referred to as a fluid vortex below and in Figure 12 with arrow 155 expressions.As what admitted in the situation of other separator, this fluid whirl produces a centrifugal action, and this centrifugal action makes the particulate matter in the fluid outwards be thrown to respectively on the inner surface 114,213 and 314 of each shell 111,211 and 311 by centrifugal force.Like this, the original fluctuation that contains granule fluid that enters the fluctuation chamber has been set up fluid whirl and has been caused that the particle in the fluid outwards moves.Subsequently, dividing plate 128,228 and 332 semispherical surface 129,229 and 333 with direct fluid annular constricted channel 130,230 and 334, have shunk the implanted layer of each fluid whirl rapidly respectively like this with regard to the inner surface of opposite shell.The speed of the helical rotation of vortex has promptly been quickened in this contraction, thereby has increased the centrifugal action of fluid.By the inner surface of shell outside each equipment that particulate matter is led, this centrifugal action has just strengthened the outside motion of carrying object no particulate matter rapidly.

Shown in arrow 155, in each fluid whirl respectively after constricted channel 130,230 by separately and 334 motions, downstream between moving period, the helical form rotating speed of fluid slows down gradually within disengagement chamber 132,232 and 336.The length of disengagement chamber allows to be thrown to the particulate matter of each fluid whirl periphery by outside the fluid whirl of gravity sedimentation in slowing down.As can be seen, the optimum length of disengagement chamber is partly determined by the character of the particulate matter for the treatment of to take out from carrying object.

Outlet 124,224 and 328 axial location help to return track towards the fluid of outlet setting up one within each disengagement chamber 132,232 and 336 within the downstream fluid vortex, as among Figure 12 by shown in the rising arrow 157.The fluid flow trace begins to depend on towards the heterodromous position of outlet the combination of several factors, comprises the concrete shape and the volume of disengagement chamber, the rotary speed of fluid whirl, the internal diameter of outlet and the length of disengagement chamber.In any case, when fluid whirl contacts end plate 147,247 and 347 respectively, begin this counter motion at least.Since centrifugal action with particulate matter outwards guiding and since the track upstream that fluid is discharged be along the chamber axially, so in fact in the fluid that moves towards outlet of helically all particulates matter therefrom discharge.Simultaneously, by gravity sedimentation outside fluid whirl or with vortex respectively along shell 111,211 and 311 inner surface 114,215 and 316 particulate matters that move down arrive end plate 147,247 and 347, and outwards be imported between end plate and the shell and enter inner pressurd vessel 141,241 and 341, to discharge by particle discharge line 144,244 and 344 immediately.As can be seen, by extending transverse to their inner pressurd vessels separately, end plate can prevent that any particulate matter from reentering disengagement chamber, thereby anti-particulate matter enters in the fluid that upstream moves with one heart with fluid whirl towards fluid outlet pipe again.

Have found that, when each constricted channel 130,230 of equipment 110,210 and 310 and 334 the inlet tube cross-sectional area 60 percent and 30 percent between scope in the time, equipment 110,210 and 310 can be worked with leaning on.The character for the treatment of separated particulate material matter from carrying object is depended in the selection of proper proportion, and the concrete size and the shape thereof that depend on the device interior size.Yet, in general, when the particle that separates when treating from carrying object is thin, will adopt the less constricted channel of area.On the contrary, when treating that institute's separated particulate material matter is big from carrying object, adopt the bigger constricted channel of area.Correspondingly, have only very little concerning the fluid of carrying by equipment or do not have pressure drop, this depends on the concrete size of used constricted channel.
