Description

Novel hydrocyclone

Technical Field

The utility model relates to a swirler technical field especially relates to novel hydraulic cyclone.

Background

The hydrocyclone is a non-moving type separation device consisting of an upper cylinder and a lower cone, and the separation principle is centrifugal sedimentation. When slurry to be separated (heterogeneous solid-liquid mixture) enters the cyclone from the periphery of the cyclone under a certain pressure, the slurry is forced to do rotary motion. Because the centrifugal force, centripetal buoyancy, fluid drag force and the like applied to the slurry are different in magnitude, the solid coarse particles in the slurry overcome the hydraulic resistance to move to the wall of the reactor and spirally move downwards along the wall of the reactor under the combined action of the gravity of the solid coarse particles, and the fine particles and most of water do rotary motion along the slurry when the fine particles and most of water are not close to the wall of the reactor because of the small centrifugal force. Under the push of subsequent feeding, the particle size of the particles is larger and larger from the center to the wall of the device, and the particles are arranged in a layered mode. The slurry flows from the column part to the cone part of the cyclone, the flowing section is smaller and smaller, under the contraction and pressing of the outer layer slurry, the inner layer slurry containing a large amount of fine particles has to change the direction and moves upwards to form an inner rotational flow, the inner rotational flow is discharged from the overflow pipe to form overflow, the coarse particles continue to move downwards along the wall of the cyclone to form an outer rotational flow, and finally the outer rotational flow is discharged from the bottom flow port to form settled sand. Thereby achieving the purpose of separation and classification.

The hydrocyclone is a common non-moving separation device, is mainly used for separating particles with different sizes in slurry, and has various types of hydrocyclones in the market at present, but the structural design of the existing hydrocyclone has the following defects: firstly, the feed inlets of the existing hydraulic cyclones are of direct injection type structures, and the impact force of the feed inlets designed by the direct injection structure is too large, so that the accelerated friction damage of a polyurethane wall in a cylinder body can be caused, the actual service life of the cylinder body is shortened, and the quick and uniform dispersion of sand and slurry after entering the cyclones is also not facilitated; secondly, present overflow pipe and the main barrel upper end formula structure as an organic whole of sinking ware soon, in case take place to damage, hardly change.
