Embodiment 1

[0033] In this embodiment, a fast and high-efficiency hydrocyclone with a quartered deflector 7 structure is adopted, and the deflectors 7 are symmetrically distributed in the center, but the number is not limited to four. In this embodiment, the height of the deflector 7 is set to 30mm, the deflector 7 is symmetrical to the center of the cylindrical cavity 6 and is tangent to the bottom flow pipe 11, and the diameter and pressure of each flushing water outlet 14 are consistent. When the particles enter the cyclone Finally, the flushing water is fed into the flushing water inlet 10 with a certain pressure, and the flushing water is discharged from the flushing water outlet 14 at a certain speed. According to the fluidization theory, under the action of the flushing water, when the axial velocity of the flushing water is greater than the initial fluidization velocity (Umf), the particles entering the bottom of the cyclone are loose and floating, forming fluidization. When the ax...

Embodiment 2

[0035] The difference between this embodiment and Embodiment 1 is that the height of the deflector 7 in this embodiment is set to 45 mm, and the deflector 7 is centrally symmetrical with respect to the center of the cylindrical cavity 6 and is tangent to the bottom flow pipe 11, so that the system operates stably After that, record the increase in calculation processing and the increase in classification efficiency.

Embodiment 3

[0037] The difference between this embodiment and Embodiment 1 is that the height of the deflector 7 in this embodiment is set to 60mm, and the deflector 7 is centrally symmetrical with respect to the center of the cylindrical chamber 6 and is tangent to the bottom flow pipe 11, so that the system operates stably After that, record the increase in calculation processing and the increase in classification efficiency.

Abstract

The invention belongs to the technical field of material separation, and discloses a fast and high-efficiency hydrocyclone, which includes a cyclone body, a flushing water distributor and a deflector, and the flushing water distributor and the deflector are respectively connected with the hydrocyclone on the cyclone body. The bottom covers are connected by welding, and the deflector is symmetrical to the center of the cylindrical cavity on the cyclone body and tangent to the bottom flow tube on the cyclone body. The material is fed in from the feed port and performs a spiral movement in the cyclone. When the particles move to the bottom of the cyclone, under the action of the upward flushing water, the fine particles are taken out and enter the internal cyclone. Under the action of the plate, the separated coarse particles are quickly diverted to the bottom flow port and discharged on the basis of the original rotary motion. The invention utilizes the principle of fluidization to strengthen the internal flow field effect of the hydrocyclone, reduces the amount of fines contained in the bottom flow, and greatly improves the separation efficiency of wide-grade materials; meanwhile, the residence time of coarse particles is reduced, and the processing capacity of the hydrocyclone is further improved .

Description

technical field [0001] The invention relates to the technical field of material separation, in particular to a fast and high-efficiency hydrocyclone. Background technique [0002] As one of the important equipment in the field of material separation in industry, the hydrocyclone uses the principle of centrifugal sedimentation to realize the separation of materials. The material enters the cyclone from the inlet under a certain pressure and produces a strong rotational movement. Under the action of centrifugal force, the coarse and heavy particles move outwards into the external swirling flow and are discharged from the sand outlet; under the action of fluid drag and centripetal buoyancy , the fine and light particles migrate inward into the inner swirl and are discharged from the overflow port, thereby completing the separation and classification of particles. It has the advantages of simple structure, high separation efficiency, simple operation, and small floor space. It ...
