Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to cyclone technical field, specifically a cyclone for ore dressing. BACKGROUND
[0002] Cyclone is the separation and classification equipment commonly used in the ore dressing process, and works by centrifugal sedimentation principle. When two-phase mixed liquid enters the inside from the periphery tangentially at a certain pressure, strong rotating shear turbulent flow is generated. Due to the size difference of coarse and fine particles in the ore pulp, the centrifugal force, centripetal buoyancy and fluid drag force they receive are different. Under the action of centrifugal sedimentation, most of the coarse particles are discharged through the cyclone underflow port, and most of the fine particles are discharged by the overflow pipe, so as to realize the separation and classification purpose. It has no moving parts and high separation efficiency, so it occupies an important position in the ore dressing process and is often used in grinding classification, desliming, concentration and other operation links.
[0003] The traditional cyclone has poor separation precision, and it is difficult to accurately realize the size and density classification of the ore with complex size composition and slight density difference, so that the concentrate grade is not ideal, and the useful minerals in the tailings are seriously lost. The equipment is severely worn, the high-speed scouring of the ore pulp aggravates the wear of the inner surface of the cyclone, especially the key parts, frequent replacement of parts increases the cost and affects the production continuity. The operation parameter adjustment flexibility is insufficient, it is difficult to quickly adapt to different ore properties and changing ore dressing process requirements, which limits its application range.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figures 1-8 In this embodiment of the present invention, a hydrocyclone for mineral processing includes...
[0030] Hydrocyclone body 1, with an overflow pipe structure 2 installed at the upper end of the hydrocyclone body 1;
[0031] The overflow pipe structure 2 includes a connecting flange 21, the upper end of which is fixedly connected to the collecting pipe 22 by bolts. The upper end of the collecting pipe 22 is fixedly connected to the filter pipe 23 by bolts. The lower end of the filter pipe 23 is provided with multiple filter screens 24, and the upper end of the filter pipe 23 is provided with spiral guide vanes 25. The upper end of the filter pipe 23 is fixedly connected to the discharge pipe 26 by bolts. The discharge pipe 26 is U-shaped, and the other end is connected to the overflow tank.
[0032] By adopting the above technical solution, the multi-layer composite design of the flow pipe structure 2, through the multi-stage filter screen 24 and the guide vane 25, achieves multi-stage fine separation of overflow slurry, effectively separating particles of different sizes and densities, greatly improving the quality of overflow products, increasing concentrate grade, and reducing the loss of useful minerals in tailings.
[0033] In this embodiment, the lower end of the connecting flange 21 is fixedly connected to the swirl column 12 by bolts, one side of the upper end of the swirl column 12 is fixedly connected to the feed connector 11 by bolts, and the other end of the feed connector 11 is connected to the raw ore pressure water tank.
[0034] The swirl column 12 is symmetrically mounted with side mounting brackets 13 on both sides, which are used to fix the swirl column 12 to the overflow tank.
[0035] The inner side of the swirling column 12 is fixedly provided with a high-alumina ceramic inner layer 14, and the lower end of the swirling column 12 is fixedly connected to the upper cone 15 by bolts. The inner side of the upper cone 15 is fixedly provided with an upper swirling inner layer 16.
[0036] The lower end of the upper vertebral body 15 is fixedly connected to the lower vertebral body 17 by bolts, and the lower vertebral body 17 is fixedly provided with a lower swirling inner layer 18; the taper of the upper vertebral body 15 and the lower vertebral body 17 decreases in a decreasing trend.
[0037] The lower end of the lower vertebral body 17 is fixedly connected to the sedimentation pipe 19 by bolts, and a sedimentation nozzle 110 is fixedly provided on the inner side of the sedimentation pipe 19.
[0038] By adopting the above technical solution, a high-alumina ceramic inner layer 14 is provided on the inner side of the cyclone column 12, and an upper cyclone inner layer 16 and a lower cyclone inner layer 18 are respectively provided on the upper cone 15 and the lower cone 17. A sand settling nozzle 110 is provided in the sand settling pipe 19. These wear-resistant inner layers can effectively resist the erosion and wear of the slurry, extend the service life of the hydrocyclone, reduce equipment maintenance costs and replacement frequency, and ensure production continuity.
[0039] The working principle of this utility model is as follows: Under pressure, the slurry enters the cyclone column 12 from the feed joint 11 connected to the pressure water tank of the raw ore. Inside the cyclone column 12, the slurry is subjected to centrifugal force, gravity and fluid resistance, and begins to be initially separated. Due to the different centrifugal forces on coarse and fine particles, most of the coarse particles move towards the inner wall of the cyclone separator, while the fine particles gather towards the center.
[0040] In the slurry after initial separation, light phase substances such as fine particles rise with the internal swirling flow and enter the overflow pipe structure 2; the light phase slurry first flows into the collection pipe 22, and then into the filter pipe 23. In the filter pipe 23, the multi-stage filter screen 24 intercepts larger particles. The remaining slurry, guided by the guide vanes 25, undergoes secondary swirling separation in the annular channel between the filter pipe 23 and the discharge pipe 26, further separating fine particles and impurities. The pure overflow slurry finally flows into the overflow tank through the U-shaped discharge pipe 26.
[0041] Meanwhile, the coarse particles and other substances of the heavy phase pass through the upper cone 15 and the lower cone 17 in sequence along the inner wall of the swirling column 12. As the taper of the upper cone 15 and the lower cone 17 decreases, the separation effect is further enhanced, and finally the particles are discharged through the sedimentation pipe 19 and the sedimentation nozzle 110.
[0042] When in use, the multi-layer composite design of the flow tube structure 2 achieves multi-stage fine separation of overflow slurry through multi-stage filter screen 24 and guide vane 25, effectively separating particles of different sizes and densities, greatly improving the quality of overflow products, increasing concentrate grade, and reducing the loss of useful minerals in tailings.
[0043] The inner side of the cyclone column 12 is provided with a high-alumina ceramic inner layer 14, the upper cone 15 and the lower cone 17 are respectively provided with an upper cyclone inner layer 16 and a lower cyclone inner layer 18, and the sand settling pipe 19 is provided with a sand settling nozzle 110. These wear-resistant inner layers can effectively resist the erosion and wear of the slurry, extend the service life of the hydrocyclone, reduce equipment maintenance costs and replacement frequency, and ensure continuous production.
