Description

Cyclone separator

Technical Field

The utility model relates to a whirl technical field especially relates to a swirler.

Background

A fluid cyclone is a common separation and fractionation device, and the centrifugal sedimentation principle is commonly used. When the two-phase mixed liquid to be separated enters the cyclone tangentially from the periphery of the cyclone under a certain pressure, strong three-dimensional elliptical strong-rotation shearing turbulent motion is generated. Because the particle size difference exists between the coarse particles and the fine particles, the coarse particles and the fine particles are subjected to different sizes of centrifugal force, centripetal buoyancy, fluid drag force and the like, and under the action of centrifugal sedimentation, most of the coarse particles are discharged through a bottom flow port of the cyclone, and most of the fine particles are discharged through an overflow pipe, so that the purposes of separation and classification are achieved.

But the conventional cyclone has poor grading effect and poor automation degree.

In view of this, the utility model provides a swirler, it is effectual to grade, and degree of automation is good, and anticorrosion and wear resistance are high.

The utility model discloses an above-mentioned technical problem is solved to following technical means: the utility model provides a swirler, includes conical duct, overflow pipe, sedimentation pipe and first overflow pipe, overflow pipe and conical duct top intercommunication, the conical duct side is provided with the inlet pipe, scribbles the carborundum coating on conical duct and the sedimentation pipe inner wall, and the conical duct bottom is provided with out the sand mouth, the overflow pipe other end and oblique cone pipe intercommunication, oblique cone pipe set up in the sedimentation pipe, first overflow pipe and sedimentation pipe top intercommunication, sedimentation pipe bottom is provided with second out the sand mouth.

The feeding pipe is provided with a flange.

The overflow pipe and the conical pipe, the overflow pipe and the inclined conical pipe and the first overflow pipe and the sedimentation pipe are fixedly connected through connecting flanges.

The inner diameter of the cone tip of the conical tube is 0.02-0.1 time of the inner diameter of the cone bottom, the settling tube is of a conical structure, and the inner diameter of the cone tip of the settling tube is 0.01-0.05 time of the inner diameter of the cone bottom.

The overflow pipe and the first overflow pipe are U-shaped pipes.

The inclined conical pipe is arranged at the upper part of the settling pipe, and the included angle between the axis of the inclined conical pipe and the horizontal plane is 5-30 degrees.

This patent adopts the two-stage whirl to select separately, and first order goes on at the conical duct, behind the inlet pipe feeding, heavier granule is followed the sand outlet nozzle ejection of compact of conical duct bottom, and other materials spill over from the overflow pipe, then goes into the taper pipe to one side, then enters into in the settling tube, then carries out the second grade whirl in the settling tube and grades, and heavier granule is followed the ejection of compact of second sand outlet nozzle, and lighter granule and thick liquids flow from first overflow pipe, have realized the two-stage and have graded. Can realize continuous feeding and continuous ejection of compact, scribble the carborundum coating on conical tube and the settling leg inner wall simultaneously, can effectually prevent erodeing and corroding of granule.

The utility model has the advantages that: the grading effect is good, the automation degree is good, and the corrosion resistance and the wear resistance are high.
