Description

Cyclone separator
The utility model relates to swirl-flow devices, particularly a kind of mud cyclone separator.
Shortcomings such as existing hydrocyclone is continued to use and is tangential direction with inlet pipe and spin chamber and advances the eddy flow of slurry and the old process for purifying of gravitational settling, has the equipment heaviness, and construction quality is poor, and drilling efficiency is low, and application life is short, and the mud purification precision is low.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, designs the process for purifying that a kind of Archimedes's of employing streamline advances slurry and helical orbit, and device is light and handy, the construction quality height, the drilling efficiency height, long service life, a kind of mud cyclone separator that the mud purification precision is high.
The purpose of this utility model is achieved in that this device comprises inlet pipe 1, bleed off pipe 2, spin chamber 3, rotating flow cone tube 4, support 5, awl tube underflow opening 6, overflow manifold 8, pressure meter 9, underflow groove 11 and spiral decline track 7, isolate umbrella 12, wherein inlet pipe 1 is connected transition position and is Archimedes's streamline shape with spin chamber 3, hydraulic loss is few and help the foundation of centrifugal force field, the internal perisporium of spin chamber 3 is provided with spiral decline track 7, lead of screw S 〉=inlet pipe 1 inner diameter d, the lower end of spin chamber 3 fixes with the up big and down small obconic rotating flow cone tube of bore 4 upper ends and is communicated with, the center of spin chamber 3 is provided with the bleed off pipe 2 that is connected as a single entity with it, the upper end of pipe is connected with overflow manifold 8, the inner chamber of spin chamber 3 is stretched in the lower end of bleed off pipe 2, the lower edge of pipe is the isolation umbrella 12 that is umbrella, make and form a purification isolated area between mortar and overflow slurry, improved the purification precision, bottom closing in place of rotating flow cone tube 4 is awl tube underflow opening 6, be connected with underflow groove 11, whole device is fixed on the support 5.
The utility model has been compared following advantage with above-mentioned prior art:
1, mud purification precision height can make the mud sand content be controlled in 0.9~2.0% scope, and quality of mud fluid is greatly improved, thereby prevent slush pump fault and drilling accident effectively, reduced hydraulic loss, comprehensive drilling efficiency improves 3~4 times, and the probing integrated cost descends about 40%;
2, this installation weight is light and handy, only is 1/4 of existing desander weight, and adopts a large amount of nylon and glass-reinforced plastic material, and saved a large amount of metal material, this device abrasion resistance and corrosion resistance are strong, and be sturdy and durable, long service life;
3, this apparatus structure is simple, and making, installation, maintenance and use are all very convenient, have alleviated labor intensity of operating personnel, and environment pollution also is subjected to effective control.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the fundamental diagram of mud cyclone separator;
Fig. 2 is the structural representation of mud cyclone separator;
Fig. 3 is spin chamber's structural representation of mud cyclone separator;
Fig. 4 is that the A-A of Fig. 3 is to structural representation;
Fig. 5 is the spiral decline track expanded view of spin chamber.
Among the figure:
1---inlet pipe 2---bleed off pipe 3---spin chamber
4---rotating flow cone tube 5---support 6---awl tube underflow openings
7---spiral decline track 8---overflow manifold
9---pressure meter 10---clip 11---underflow grooves
12---isolate umbrella
As Fig. 1,2,3,4, shown in 5, the structure of this device as mentioned above, when mud under the effect of sand pump pressure head, by inlet pipe 1, enter spin chamber 3 at a high speed along Archimedes's streamline, the spiral decline track 7 that on spin chamber's 3 internal perisporiums, is provided with, rotatablely move as high-speed screw downwards, thereby produced a huge centrifugal force field, design lead of screw S 〉=inlet pipe 1 inner diameter d, both avoided advancing to starch the hydraulic loss that causes of mutual interference mutually of fluid and eddy flow fluid, quickened the descending motion of solid phase particles again, the bigger solid phase particles of density and shape is thrown toward barrel in the mud under centrifugal action, and do the spiral descending motion, after an awl tube underflow opening 6 be expelled in the coupled logical underflow groove 11; Meanwhile, because the high speed of mud rotation, center at rotating flow cone tube 4 forms a low-pressure area, the lightweight slurries that density is less, in low-pressure area, do the spiral ascending motion, and from awl tube underflow opening 6 suction part air, after bleed off pipe 2 discharge currents that are connected with rotating flow cone tube 4 tops to coupled logical overflow manifold 8, are finished the purification process of mud.For preventing to be taken away by the higher lightweight overflow of flow velocity from the mortar of spin chamber's landing, 2 times pipes of bleed off pipe make to have formed a purification isolated area between mortar and the overflow slurry along the isolation umbrella 12 of entrance, have improved the purification precision.
Spin chamber 3 adopts the nylon integral cast with bleed off pipe 2, inlet pipe 1 that steel are made and spin chamber 3 interfix embedding connection mutually, and inlet pipe 1 inwall is provided with nylon bush.
Upper and lower awl tube adopts the nylon monomer casting, by clip 10 upper and lower two awl tubes is connected to rotating flow cone tube 4, is provided with the lining that high-abrasive material polyurethane is made at its slower conical tube inwall, and prolong application life greatly.
Manifold adopts clamp connection to fix, and all manifold, clip and underflow groove 11 all adopt glass-reinforced plastic material to make.
Said structure has guaranteed the intensity of this device, simplifies the structure again, has alleviated weight, has improved abrasion resistance and corrosion resistance, has prolonged application life.
The overflow manifold 8 of this device is connected with bleed off pipe 2 can be according to the two-way any selection overflow emission direction in work-yard.
The support 5 of this device adopts worn-out mouthful of design, adopts pressing plate to fix between rotating flow cone tube 4 and the support 5, and is provided with carrying handle, makes migration, installation, maintenance and use convenient.
