Technical Field

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 bottom flow port 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.

The product is more uniform under the action of vortex when being fed, the internal flow field has better symmetry and stability, and the abrasion of fluid to the wall of the device is reduced.

A plurality of feeding pipes 12 are connected on the side wall of the feeding volute 10 in a through manner of circumferential array, and a dilution pipe 13 is arranged at the through position of each feeding pipe 12 and the feeding volute 10. The inner wall of each feeding pipe 12 is provided with a stepped surface 121, and the stepped surface 121 is used for decreasing the cross-sectional area of a flow passage in the feeding pipe 12 along the feeding direction so as to improve the feeding flow rate.

In the present invention, the dilution pipe 13 includes a water diversion box 131 penetrating the sidewall of the feed volute 10, and a water inlet pipe 132 penetrating the water diversion box 131.
