Abstract

The utility model relates to a solid-liquid separator, including a cyclone tube 4 and a cone tube 5 with an outlet at the bottom. The technical key points are that a cyclone generator 2 is fixed on the upper portion of the cyclone tube, and a liquid inlet tube1 is crossly fixed on the side of the cyclone generator, an inner pipe of the liquid inlet tube is in communication with the vacuum cavity of the cyclone generator on which flow curves are Archimedes spirals, involutes and other curves alike, then a center pipe 7, of which the upper portion is connected with a overflow pipe 9, is fixed at the center of the cyclone generator, and the upper portion of the center pipe extrudes out from the cyclone generator and the upper portion extrudes into the cyclone tube. The separator is simple in structure and highly qualified in mud-separating.

Description

The high-efficiency cyclone separator

The utility model relates to a kind of equipment for separating liquid from solid, is specially adapted to the equipment for separating liquid from solid in drilling mud desanding, desilt operation and other industry.

In oil drilling or other geological drilling operation, to from well, be carried on the ground with high pressure drilling mud through the earth cuttings of drill bit fragmentation.Because mud will use a large amount of valuable chemicals preparations, on the mud that returns to utilize again after treatment.At present, the operation that mud veclamation is handled is: will on the mud that returns remove bigger rock bits particle by vibratory sieve, and then remove the fine sand particle and remove the shale particle through desilter through desander, reuse through the mud after the above-mentioned recycling.Present employed desander and desilter all are to realize through rotational flow separation, but this cyclone separation device is because structure is more outmoded, and separating effect is all not ideal enough, and fine sand particle and shale particle can not be removed simultaneously.

The purpose of this utility model is rational in infrastructure, good separating effect, and can finish the high-efficiency cyclone separator of removing fine sand particle and two kinds of functions of shale particle simultaneously.

The utility model is achieved in that it includes a whirl cylinder and is fixedly mounted on the awl tube of this whirl cylinder lower end, and the lower end of this awl tube has a underflow opening of draining silt particle.Be installed with a rotational flow generator in the upper end of whirl cylinder, the side of this rotational flow generator tangentially is installed with the feed tube that communicates of inner chamber circulation with it, and the inner chamber passage curve of rotational flow generator is spiral of Archimedes or involute.Be installed with a central tube in the center of rotational flow generator, the lower end of this central tube extend in the whirl cylinder, and the upper surface of rotational flow generator is stretched out in the upper end, and formation is fixedlyed connected in the upper end of its central tube with overflow pipe.

Operation principle of the present utility model is: utilize after the mud supercharging that mortar pump crosses vibration processing by pipeline input rotational flow generator, through the water conservancy diversion of rotational flow generator, mud is rotated in making the annular space that revolves between tube and the whirl cylinder.Under action of centrifugal force, the solid phase particles that weight is bigger is thrown toward skin, and the less liquid of severe remains on the internal layer of toroidal cavity.Along with gravity and the slush pump double action to mud pressure, mud moves to the whirl cylinder bottom in rotation.After in mud enters into the awl tube, install because this awl tube is up big and down small structure, the internal diameter of awl tube diminishes gradually, and the flow velocity of mud continues to increase, the solid phase particles that is thrown to the cone inner surface is constantly descending along cone wall, after the underflow hole discharge of awl tube bottom.The liquid of awl tube middle part is discharged this separator through central tube, overflow pipe under the effect of hydraulic coupling, be transported to drill site again and use.

Because the inner chamber passage curve of the rotational flow generator of this separator adopts spiral of Archimedes or involute, steady when making liquid flow to into rotational flow generator, behind rotational flow generator, the rotary speed of mud is fast, do not produce turbulent flow, make the solid-liquid separation effect of separator improve a lot.This separator not only can separate removes the fine sand particle, and can also separate the shale particle.Simultaneously, this separator can also separate and carry out water-oil separating to the impurity of gas.

Fig. 1 is a structure principle chart of the present utility model;

Fig. 2 is the vertical view of Fig. 1.

Below in conjunction with accompanying drawing the utility model is described in detail.

Whirl cylinder 4 of the present utility model can be a cylinder, also can be the circular cone tube.The awl tube 5 that is fixedly mounted on whirl cylinder 4 lower ends is devices that a collection is separated solid matter, and collected separated object is discharged through the lower end of underflow opening 6.Rotational flow generator 2 is fixedly mounted on the upper end of whirl cylinder 4.Tangentially be installed with the feed tube 1 that communicates of inner chamber runner with it in the side of rotational flow generator 2, through this feed tube 1 mud that needs separate is imported rotational flow generator 2, make it to produce rotation, in order to make liquid enter rotational flow generator 2 uniformly and stably, the inner chamber passage curve of rotational flow generator 2 selects for use spiral of Archimedes, involute or other to have the curve of similar features.Derive for the mud after will separating, be installed with a central tube 7 in the center of rotational flow generator 2, the lower end of this central tube 7 extend in the whirl cylinder 4, and the upper surface of rotational flow generator 2 is stretched out in the upper end.The upper end of central tube 7 can directly connect overflow pipe 9 with mud output, and the upper end of central tube 7 also can connect an overflow separator tube 10 earlier, connects overflow pipe 9 again.For the mud in the separator is steadily exported, the inner chamber passage curve of overflow separator tube 10 adopts spiral of Archimedes, involute or other similar curve, and at this moment overflow pipe 9 is fixedly mounted on the tangential of overflow separator tube 10.

In order further to improve the separating effect of cyclone separator, be set with one in the outside of central tube 7 and make coil 3, the side, upper end of making coil 3 is installed with a bypass pipe 8, and the endoporus of this bypass pipe 8 communicates with the looping pit of making coil 3 and central tube 7 formations.The purpose of making coil 3 at the outside of central tube 7 suit is the mud in the whirl cylinder 4 outwards is divided into three parts from the lining, skin is the solid phase particles that is separated, this particle is discharged from the underflow opening 6 of awl tube 5 lower ends, and nexine is separated good mud, discharges from central tube 7.The intermediate layer is for containing less solid phase particles mixing mud; if these mud are discharged from central tube 7; will influence the quality of mud; at this moment; this partially mixed mud is by central tube 7 and the looping pit of making coil 3 formations; bypass pipe 8 sends back to mortar pump, sends separator again back to by mortar pump and separates again, has so just guaranteed the quality of separated back mud.
