Swirler of gradually-expanding barrel

Technical Field

The utility model belongs to the technical field of hydrocyclone preparation technique and specifically relates to a swirler of gradually expanding shape barrel that simple structure, separation efficiency are high, the running cost is low, the unit throughput is high, the energy consumption is low.

Background

As is well known, hydrocyclone separation technology is a heterogeneous mechanical separation process that utilizes density differences for multiphase separation, and therefore the material suitable for use in hydrocyclones must be a multiphase liquid mixture having a certain density difference.

The separation process is a process for making the materials more orderly, and the size of the separating capacity of the cyclone is an important index for measuring the effectiveness of the separation process. The mixed material enters the cyclone along the tangential direction, most of the mixed material forms main flow, most of solid particles carried by fluid are separated in the main flow, but due to the existence of solid boundaries, part of the material can not be effectively separated near the top cover of the cylinder body of the cyclone, so that short circuit is directly discharged by overflow, namely short circuit flow (also called under-cover flow), the separation efficiency is reduced due to the existence of the phenomenon, the single machine processing capacity of the cyclone is limited, a large-diameter cyclone is adopted, due to the existence of the short circuit flow, the separation efficiency is lower, the precision is poor, the processing capacity can be increased due to the series connection of a plurality of the cyclone, but with the increase of the number of the series connection of the plurality of the cyclone, the occupied area is increased.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

as shown in the attached drawing, the cyclone of the gradually-expanding cylinder body comprises a cylinder body, a conical body 1, a feeding pipe 2, an overflow pipe 3 and a bottom flow port 4, wherein the side surface of the cylinder body is connected with the feeding pipe 2, the middle part of the upper part of the cylinder body is provided with the overflow pipe 3, the lower end of the overflow pipe 3 extends into the cylinder body, the upper end of the overflow pipe 3 extends out of the cylinder body, the lower end of the cylinder body is connected with the conical body 1, and the bottom of the conical body 1 is provided with the bottom flow port 4, the cyclone is characterized in that the cylinder body is a gradually-expanding circular-table-shaped cylinder body 5 with a small upper end diameter and a large lower end diameter, the circular-table-shaped cylinder body 5 is respectively connected with the feeding pipe 2, the overflow pipe 3 and the conical body 1, the cone angle of the circular-table-shaped cylinder body 5 is 70-90 degrees, the diameter of the overflow pipe 3 is 0.1-0.2 times of the sum of the, the equal-angle cones are connected with each other through flanges, the round platform type cylinder body 5, the cone body 1, the feeding pipe 2, the overflow pipe 3 and the underflow port 4 are all in a form of a steel shell and a lining, and the lining is made of ceramic, polyurethane or rubber.

When the utility model is used, the mixed material enters the cone-shaped cylinder 5 through the inlet pipe 2, a high-speed rotating flow field is generated in the cone-shaped cylinder 5, wherein the component with high density moves downwards along the axial direction under the action of the rotating flow field and moves outwards along the radial direction, and moves downwards along the wall after reaching the cone-shaped body 1 and is discharged from the underflow port 4 to form an outer rotational flow, the component with low density moves towards the direction of the central axis, and forms an inner rotational flow moving upwards at the axis center and is discharged from the overflow pipe 3, and finally, the purpose of two-phase separation is achieved, because the existing cone-shaped cylinder is changed into the cone-shaped cylinder 5, the relative area of the upper end surface of the cylinder is reduced, the distance between the mixed material and the cylinder wall of the cylinder is shortened, thereby the short-circuit flow is lightened, the fluid tangential velocity is increased, the turbulent kinetic energy intensity of the internal flow field is reduced, and the cone-shaped body 1 is set into, the utility model discloses a long granule is at the dwell time of swirler wall, provides stable separation space, improves separation efficiency, and the improvement of this structure can be through the up end diameter of barrel unchangeable, increase the terminal surface diameter under, and then change again and be connected the realization with conical body 1 that the terminal surface diameter is the same down, change simultaneously and satisfy the overflow pipe 3 that requires, also can be through reducing the up end diameter of barrel and change the overflow pipe 3 that satisfies and realize, the utility model discloses because the barrel be established as the little flaring round platform type barrel 5 that the upper end diameter is little, the lower extreme diameter is big, round platform type barrel 5 is connected with inlet pipe 2, overflow pipe 3 and conical body 1 respectively, the cone angle of round platform type barrel 5 be 70 degrees-90 degrees, the diameter of overflow pipe 3 be 0.1-0.2 times of the sum of the up end diameter of round platform type barrel 5 and lower terminal surface diameter, conical body 1 establish to be by three constant angle cones at least and constitute, the equal-angle cones are connected with each other through the flanges, and the device has the advantages of simple structure, high separation efficiency, low operation cost, high single machine processing capacity, low energy consumption and the like.
