And after the material enters the flow field of the hydrocyclone, high-speed centrifugal spiral movement is carried out, coarse and heavy particles are discharged from the bottom flow port, and fine particles are discharged from the overflow port under the influence of centrifugal force, buoyancy, flow field drag force and the like, so that the separation of the coarse and fine particles is completed.

However, both theory and practice find that a part of fine particles which cannot be avoided by the prior cyclone are wrapped by the flow field and the coarse particles and discharged from the bottom flow port, so that the separation efficiency of the cyclone is affected.

According to the prior patent retrieval, a water jacket type rotational flow centrifugal separation device (patent number: CN 110624684A) applied by Sichuan academy of engineering; a hydrocyclone with diversion trenches and flushing water applied by the middle smelting engineering Co., ltd (patent number: CN 113814076A). Compared with the conventional hydrocyclone, the hydrocyclone has a complex structure, is difficult to process and mass produce, and is easy to block and lose efficacy in the internal holes.
