Background
The fluid cyclone is a common separation and classification device, and after two-phase mixed liquid to be separated enters the cyclone tangentially from the periphery of the cyclone at a certain pressure, strong three-dimensional elliptical strong-rotation shearing turbulent flow 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 such as centrifugal force, centripetal buoyancy, fluid drag force and the like, large particle materials are close to the inner wall of the cyclone, and small particle materials are far away from the inner wall of the cyclone; under the action of centrifugal sedimentation, most of coarse particles are discharged through a sand settling nozzle at the bottom of the cyclone, and most of fine particles are discharged through an overflow pipe at the top, so that the separation and classification purposes are achieved.
After primary size mixing of the existing cyclone, the slurry is directly pressed into the cyclone through a slurry pump for classification, but when coarse particles approach the inner wall of the cyclone, part of fine particles are mixed, so that the classification efficiency cannot be further improved, and the classification mass efficiency of the mining cyclone is 50-65% more; meanwhile, coarse particles directly contact the inner wall of the cyclone, and the lining of the cyclone is quickly abraded.
For those skilled in the art, how to further improve the classification efficiency of the cyclone is a technical problem to be solved at present.

Detailed Description
The core of the invention is to provide a high-efficiency swirler, which utilizes a high-pressure water film to bring small particle impurities mixed among large particles to the center, thereby improving the classification efficiency of the swirler.
In order to make the technical solution of the present invention better understood by those skilled in the art, the high efficiency cyclone of the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1A and 1B, which are respectively a front view and a top view of a high efficiency cyclone provided by the present invention; the cyclone comprises a cyclone body 1, wherein the cyclone body 1 is hollow and has a conical cylindrical structure, slurry can spirally move in the cyclone body 1, large particles are discharged from a port A at the lower part, and small particles are discharged from a port B at the upper part; the side wall of the rotational flow body 1 is connected with a feed pipe 2 for conveying slurry and a water inlet pipe 3 for conveying high-pressure water; the ground paste flows into whirl body 1 along the tangent plane direction of 1 inner wall of whirl body, and the ground paste is helical motion, receives the effect of centrifugal force, and the large granule is closer to the inner wall surface of whirl body 1 for the tiny particle.
The water inlet pipe 3 enables high-pressure water flow to flow in along the tangent plane of the inner surface of the rotational flow body 1, the high-pressure water enters the space between the slurry and the inner surface of the rotational flow body 1 to generate a high-pressure water film, particles in the slurry are spaced from the inner wall surface of the rotational flow body 1, and the high-pressure water forms a buffer layer, so that the impact of the slurry particles on the inner wall surface of the rotational flow body 1 is reduced.
As shown in fig. 2, be the inside local structure chart of whirl body 1, C shows the high pressure water film in the drawing, the ground paste granule receives the centrifugal force to have the trend that moves to the right, the extrusion water film, because the density of water is less than the density of ground paste granule, water receives the extrusion and moves to the left, direction as shown by the arrow in fig. 2, water flows between the gap between the large granule, when the inboard velocity of flow of water is greater than the velocity of motion of smuggleing tiny particle to the outside secretly, it moves to the left to drive the tiny particle that is mingled with in the large granule, get into the region of tiny particle, thereby get rid of the tiny particle in the large granule, the separation degree promotes between large granule and the tiny particle, the purity that obtains is higher.
On the basis of the scheme, the feeding pipe 2 is arranged at the top of the side wall of the rotational flow body 1, the height of the water inlet pipe 3 is smaller than or equal to that of the feeding pipe 2, and high-pressure water sprayed from the water inlet pipe 3 can enter between slurry and the inner surface of the rotational flow body 1 from the beginning of entering the rotational flow body 1.
Furthermore, the connection point of the water inlet pipe 3 and the rotational flow body 1 is positioned behind the connection point of the water inlet pipe 2 and the rotational flow body 1, namely, slurry flowing out of the water inlet pipe 2 firstly enters the rotational flow body 1, and high-pressure water flowing out of the water inlet pipe 3 then enters the rotational flow body 1, so that the slurry can be separated by the high-pressure water.
As shown in fig. 3A, it is a schematic view of the top view of the water inlet pipe 3 and the material inlet pipe 2; FIG. 3B is a cross-sectional view taken along line D-D of FIG. 3A; preferably, the water inlet pipe 3 is arranged on the outer side wall of the material inlet pipe 2, the slurry and high-pressure water enter the rotational flow body 1 basically synchronously, the high-pressure water film is formed before the slurry contacts the inner wall of the rotational flow body 1, and isolation is realized at the initial stage of slurry entering.
The high-pressure water film and the slurry keep synchronous motion, the flowing speed of the high-pressure water film entering the rotational flow body 1 is larger than the flowing speed of the slurry entering the rotational flow body 1, and fine particles can be removed only when water flow has high enough speed, so that fine particles doped in large particles can be removed at a higher inflow speed in a larger range.
Preferably, the pipe heights of the water inlet pipe 3 and the water inlet pipe 2 are equal, and the width of the water flow when entering is equal to the width of the slurry when entering.
