Cyclone separator

Technical Field

The utility model relates to a select separately technical field, specifically speaking relates to a swirler.

Background

A cyclone is a common separation 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 flow guide pipe 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.

Chinese patent No. CN207169971U discloses a special water conservancy swirler for magnetizing roasting fine grading, which comprises a cylindrical section cavity and two-stage conical section cavities, wherein the cylindrical section cavity and the conical section cavities form a separation cavity; the cone angle of the upper first-stage conical section cavity is larger than that of the lower second-stage conical section cavity, and the length of the first-stage conical section cavity is smaller than that of the second-stage conical section cavity; the upper part of the cylindrical section cavity is connected with an overflow pipe along the central axis, and the overflow pipe is also connected with an external connecting pipe of the overflow pipe; a flow guide pipe is connected to the lower part of the cavity of the secondary conical section along the central axis; the feeding pipe is further arranged on the side face of the cylindrical section cavity and is communicated with the cylindrical section cavity through a spiral line flow passage, the spiral line flow passage is communicated with the cylindrical section cavity and is communicated with the cylindrical section cavity, and a wrap angle formed by the spiral line flow passage and the cylindrical section cavity is in the range of 180-270 degrees. The hydrocyclone has the advantages of high grading precision and efficiency, good overflow fineness and low content of fine particles carried by underflow.

Chinese patent No. CN203061305U discloses a novel hydrocyclone with gradually changing cone angle, which is provided with a hollow cylinder and a cylinder body composed of an inverted cone communicated with the cylinder, wherein the cylinder body is respectively provided with a feeding pipe and an overflow pipe, the inverted cone is provided with a flow guiding pipe, and the novel hydrocyclone is characterized in that the conical surface of the inverted cone is provided with an arc convex surface, the arc convex surface is gradually reduced from the middle to two ends along the axial direction and smoothly transits with the conical surface of the inverted cone, the inner wall of the inverted cone can be a complete arc convex surface, and also can be provided with an arc convex surface on one section of the inner wall of the cone, and two ends of the arc convex surface are smoothly transited with the conical surface of the inner wall of the inverted cone, thereby changing the internal flow field of the hydrocyclone, changing the retention time of materials in the hydrocyclone, improving the tangential speed of the fluid and, the separation granularity of the cyclone is adjusted, and the separation efficiency of the cyclone is improved.

the prior cyclone has the following defects in the using process: (1) when the viscosity, solid concentration and particle size composition of the feed slurry change, the separation particle size and separation effect of the cyclone change along with the change, so that the separation effect is poor; (2) when the particle size is larger, the lower half part of the cone is easy to wear, so that the service life of the cyclone is short.
