Description

Technical Field

[0001] The utility model belongs to the technical field of zinc ore germanium separation, and in particular relates to a centrifugal separation device for enriching germanium elements in zinc concentrate. Background Art

[0002] Germanium is found in low concentrations in nature and often coexists with metals like zinc in zinc concentrate. To efficiently utilize this resource, the enrichment and separation of germanium from zinc concentrate has become a key technology. Currently, this is primarily achieved through hydrometallurgical processes.

[0003] Existing wet separation equipment often suffers from poor solid-liquid mixing when processing zinc concentrate. This results in inefficient reaction between the germanium in the zinc ore and the solvent, which in turn affects separation efficiency. This uneven solid-liquid mixing prevents the solvent from fully contacting and dissolving the germanium, resulting in low germanium recovery and insufficient separation purity.

[0004] Therefore, in view of the problem that the existing wet separation device for enriching germanium in zinc concentrate has poor solid-liquid mixing, resulting in low reaction efficiency and poor separation effect between the zinc ore germanium and the solvent, a centrifugal separation device for enriching germanium in zinc concentrate can be designed. Utility Model Content

[0005] In order to overcome the problem of low reaction efficiency and poor separation effect of germanium element in zinc ore and solvent caused by poor solid-liquid mixing in the existing wet separation device for enriching germanium element in zinc concentrate.

[0007] Preferably, the external zinc ore powder is mixed with the germanium element reaction solvent and then discharged into the centrifugal water spray channel from the circulating feed pipe, and the high-speed mixture is sprayed out from the tangential angle water spray port at an inclined angle to the inner wall of the centrifugal bin. Due to the shape of the inverted cone, the sprayed material flow is centrifugally rotated along the inner wall of the centrifugal bin. When the overflowed liquid is discharged from the circulating external discharge pipe, it is collected and the liquid is re-circulated and pumped out from the circulating feed pipe by a pump, thereby realizing the high-speed centrifugal mixing reaction function of the liquid and solid in the centrifugal bin, effectively improving the efficiency of the reaction of the germanium element with the solvent and the separation efficiency of the impurities in the zinc ore, and solving the problem of the existing wet separation device for enriching the germanium element in zinc concentrate, which has low reaction efficiency and poor separation effect between the zinc ore and the germanium element and the solvent due to poor solid-liquid mixing.

[0008] Preferably, an inverted conical platform is provided inside the centrifugal bin; a sealing plate is provided at the upper end of the inverted conical platform, and the sealing plate is fixedly connected to the inner wall of the centrifugal bin and the inverted conical platform; a centrifugal water spray channel is provided inside the inverted conical platform; tangent angle water spray outlets are arranged along the edge of one side of the inverted conical platform, and the tangent angle water spray outlets are arranged at an angle with the tangent angle of the outer wall of the inverted conical platform, and the tangent angle water spray outlets are connected to the centrifugal water spray channel; a circulating external exhaust pipe is connected to the interior of the centrifugal bin.

[0013] Preferably, an explosion-proof observation window is provided around the outer wall of the upper end of the injection bin, and the explosion-proof observation window is sealed and fixedly connected to the injection bin.

[0014] Beneficial effects of the utility model:

[0015] 1. Existing wet separation devices for enriching zinc concentrate with germanium have the problem of low reaction efficiency and poor separation effect between the zinc ore and the solvent due to poor solid-liquid mixing. This invention solves the problem of low reaction efficiency and poor separation effect between the zinc ore and the solvent due to poor solid-liquid mixing in existing wet separation devices for enriching zinc concentrate with germanium. External zinc ore powder is mixed with a germanium reaction solvent and then discharged into a centrifugal water spray channel through a circulating feed pipe. The high-speed mixture is sprayed out from a tangential angle water spray port at an inclined angle toward the inner wall of the centrifugal bin. Due to the shape of the inverted cone, the sprayed material flow undergoes centrifugal rotation along the inner wall of the centrifugal bin. When the overflowing liquid is discharged from the circulating external discharge pipe, it is collected and recirculated and pumped out from the circulating feed pipe by a pump, thereby achieving a high-speed centrifugal mixing reaction function between the liquid and solid in the centrifugal bin, effectively improving the efficiency of the reaction between the germanium and the solvent and the separation efficiency of impurities in the zinc ore. This solves the problem of low reaction efficiency and poor separation effect between the zinc ore and the solvent due to poor solid-liquid mixing in existing wet separation devices for enriching zinc concentrate with germanium.

Through the setting of solid discharge pipe and liquid discharge pipe, the liquid discharge pipe is used to separate and discharge the liquid on the upper layer of the solid after the reaction is completed, while the solid discharge pipe is used to separate and discharge the solid material on the lower layer, thereby realizing the function of solid-liquid separation.

[0026] During operation, the external zinc ore powder is mixed with the germanium element reaction solvent and then discharged into the centrifugal water spray channel 105 from the circulating feed pipe 202. The high-speed mixture is sprayed out from the tangential angle water spray port 106 at an inclined angle to the inner wall of the centrifugal bin 101. Due to the shape of the inverted cone 102, the sprayed material flow is subjected to centrifugal rotation along the inner wall of the centrifugal bin 101.

The high-speed mixture is sprayed out from the tangential angle water spray port 106 at an inclined angle toward the inner wall of the centrifugal chamber 101. Due to the shape of the inverted conical platform 102, the sprayed material flow is centrifugally rotated along the inner wall of the centrifugal chamber 101. When the overflowed liquid is discharged from the circulating external discharge pipe 3, it is collected and recirculated and pumped out from the circulating feed pipe 202 by a pump, thereby realizing the high-speed centrifugal mixing reaction function of the liquid and solid in the centrifugal chamber 101, effectively improving the efficiency of the reaction between the germanium element and the solvent and the separation efficiency of the impurities in the zinc ore, and avoiding the problem of low reaction efficiency and poor separation effect between the zinc ore and the germanium element and the solvent in the existing wet separation device for enriching the zinc concentrate with germanium due to poor solid-liquid mixing.
