Embodiment Construction

[0016] Implementation of the present invention provides an overflow pipe-based cyclone on-line regulator, its main structure is that the upper overflow chamber 3 and the lower cylinder separated by a partition 11 are connected in series on the periphery of the overflow pipe 11 6. The vane device 12 is installed in the overflow pipe 11. By controlling the insertion depth of the vane device 12 in the overflow pipe, the flow field characteristics of the fluid inside the cyclone are affected, and the classification of the cyclone product is realized. On-line adjustment of particle size or product ash.

[0017] When implementing the above technical solution, the blade device 12 is provided with at least three blades, or more than three blades are arranged to form the blade device 12, and the vertical direction is parallel to the central axis, and the inclination angle α of the blades is set to be between 0-90°. All can be, and the interval between every adjacent blade is the same. ...

Abstract

The invention discloses an online hydrocyclone regulating device based on an overflow pipe. According to the online hydrocyclone regulating device based on the overflow pipe disclosed by the invention, the periphery of the overflow pipe is connected in series with an upper overflow chamber and a lower cylinder body which are divided by a baffle, a blade device is installed in the overflow pipe, the flow field characteristics of a fluid in a hydrocyclone is influenced by controlling the insertion depth of the blade device in the overflow pipe, and then the product classification size or the product ash content of the hydrocyclone can be regulated on line. With the adoption of the online hydrocyclone regulating device, as the blade device is added into the overflow pipe, and the tangential and axial speeds, the turbulence intensity and the air column characteristics in the hydrocyclone are influenced by regulating the insertion depth of the blade device by virtue of a lead screw, the purpose of regulating structure parameters of the overflow pipe, a bottom flow mouth and the like to be same is fulfilled, and the purpose of regulating the product classification size or the product ash content on line is realized.

Description

technical field [0001] The invention relates to a classifying cyclone and a sorting cyclone, in particular to an on-line regulating device for the cyclone based on an overflow pipe. Background technique [0002] Cyclones are widely used in the separation of liquid heterogeneous mixtures due to their simple structure, low equipment cost, and large processing capacity. When the mixed liquid enters the cyclone tangentially from the periphery of the cyclone, a strong rotational shear turbulent movement is generated. Due to the difference in density (particle size) between different particles, the centrifugal force, gravity, fluid drag, etc. Also different. Most of the particles with high density (particle size) are thrown to the wall of the cyclone under the action of centrifugal force and gravity, and then discharged through the outlet at the bottom. Most of the particles with small density (particle size) rotate to a certain extent and then are discharged through the overflo...
