Abstract
The invention relates to a method and a device for producing high-purity indium granules and belongs to the field of high-purity nonferrous metal casting in metallurgical industry. The method comprises: a first step of heating refined indium for melting, in which the temperature is kept between 170 and 300 DEG C; a second step of starting compressed air, in which air pressure is maintained at 3 to 8 kg/cm<2>; a third step of placing an indium mold on a movable clamping plate of a rotating device, in which the compressed air is used to make the movable clamping plate clamp tightly the mold and the rotation of the motor is started; and a fourth step of pouring molten refined indium into the mold through a funnel, cooling and getting out the refined indium to obtain the high-purity high-standard indium granules. The method is high in production speed, low in energy consumption and simple in equipment processing, and meets requirements on large-scale production. Because the method adopts special device and avoids the addition of other materials, the purity of the indium granules is not influenced in the production process, and pollution and pollutant discharge are avoided in the production process.

At present, existing technical process of producing the indium pearl mainly is smart indium (purity is 99.995%) fusing back to be splashed in the cooling fluid under the gravity effect by aperture make, and its major defect is: indium pearl granular size differs; Because capillary effect, each indium pearl can stay a little tail when breaking away from aperture; Drop in the cooling fluid, the indium pearl is easy to wrap into new impurity again.The indium pearl actual purity that existing method is produced generally about 99.9%, has a strong impact on effective utilization of indium pearl.Therefore, existing method of producing the indium pearl has been difficult to satisfy actual needs.
Summary of the invention
One of the object of the invention provides a kind of method of making the indium pearl, is characterized in can making by this method the uniform particles of indium pearl, the diameter unanimity, and also the purity of assurance indium pearl is more than 99.995%.
Two of the object of the invention provides a kind of device of realizing the foregoing invention purpose.
One of purpose of the present invention realizes by following technological approaches.Specific embodiment is: the first step, and with smart indium heat fused, temperature is controlled between 170 ℃～300 ℃; Second step, open compressed air, make stable gas pressure at 3～8kg/cm
2The 3rd step, on the ambulatory splint of whirligig, place indium pearl mould, compressed air is opened the motor rotation with the ambulatory splint clamping mold; The 4th step, the smart indium of fusing to be poured in the mould by funnel, take out the cooling back, promptly forms high-purity high standard indium pearl.
Two of purpose of the present invention realizes by following technological approaches.It contains blowing plant, whirligig, control panel, ambulatory splint, indium pearl mould, motor, funnel, air pressure adjustment switch, rotating speed adjustment switch, timer, wherein, be provided with two ambulatory splints that are connected with blowing plant in the whirligig, ambulatory splint is spacing on motor shaft, indium pearl mould is between two ambulatory splints, the top of indium pearl mould is communicated with funnel, and the bottom is connected with motor; Whirligig is provided with control panel, and control panel is provided with the rotating speed that is connected with motor and adjusts switch and timer.
It is fast that the present invention has speed of production, and energy consumption is low, and equipment processing is simple, and being suitable for large-scale production needs.Owing to adopt isolated plant, do not have other material and add, do not influence purity in the production process, and pollution-free in the production process, do not have and dye the thing discharging.
With 99.995% smart indium is raw material, the 5 millimeters indium pearls of high-purity diameter that the present invention produces and the comparison of produced in conventional processes
| Granularity | Diameter (mm) | Circularity | Purity | |
| Conventional method | Inhomogeneous | 4～6 do not wait | ±20％ | 99.9％ |
| The present invention | Evenly | 5±0.1 | ±2％ | 99.995％ |
