Abstract
The utility model relates to an aluminum shot preparing device, in particular to a high-purity and high-activity aluminum shot preparing device. The high-purity and high-activity aluminum shot preparing device is characterized in that a cooling and rotating disc is installed below an aluminum shot preparing die with holes evenly distributed in the bottom, the lower end of the cooling and rotating disc is connected with a motor through a transmission chain, and the cooling and rotating disc is filled with cooling liquid. According to the high-purity and high-activity aluminum shot preparing device, discontinued small liquid drops are formed when molten aluminum flows down through the holes evenly distributed in the bottom of the aluminum shot preparing die, the small liquid drops directly fall into the cooling liquid, the contact between the molten aluminum and the air is reduced through the protection of inert gases, and therefore granularity and surface activity of aluminum shots are effectively guaranteed. The aluminum shot preparing device has the advantages of being simple in structure, high in efficiency, low in production cost and the like. The aluminum shot preparing device can be used for industrial production of high-purity aluminum shots used for rare metallic oxide aluminothermic reduction.
Description
Technical field
The utility model relates to a kind of Preparation equipment of aluminium shot, particularly a kind of preparation facilities of high-purity high activity aluminium shot.
Background technology
Aluminium shot refers to be shaped as the alumina particles product of go stone.High-purity high activity aluminium shot is widely used in high Purity Rare Metals oxide aluminothermic reduction aspect, such as the preparation of the metals such as High-purity Tantalum, niobium, titanium as a kind of high-efficient metallurgical reducing agent.The granularity of aluminium shot and activity are the important parameters that determines reduction removal of impurity effect in the Fine Metallurgy process.Particle mean size is less, more high the carrying out that more is conducive to reduction reaction of surface-active, and the effect of removal of impurities is better, finally can obtain highly purified reactive metal.
The method for preparing at present aluminium shot mainly is Mechanical Method, is that aluminium ingot is rolled into diameter is aluminium wire about 12mm, then is cut into the aluminium section.The method is being rolled into aluminium ingot in the process of aluminium wire, because aluminium and oxygen have very strong affinity, along with attenuating of aluminium wire diameter, oxidation very easily occurs on the aluminium wire surface, forms stable oxide, thereby reduces its activity.
Summary of the invention
The purpose of this utility model is to solve the defective that prior art exists, and provides a kind of with the direct beans processed of aluminium liquid, and the preparation facilities of the high high-purity high activity aluminium shot of aluminium shot epigranular, the surface-active of producing.
The technical solution of the utility model is: a kind of preparation facilities of high-purity high activity aluminium shot, its feature is in that uniform porose aluminium shot prepares the mould bottom cooling rotating disc is installed in the bottom, cooling rotating disc lower end links to each other with motor by driving-chain, in the cooling rotating disc cooling fluid is housed.
Cooling fluid in the above-mentioned cooling rotating disc is carried out circulating cooling by circulating pump.
Prepare mould and cooling is equipped with seal closure between the rotating disc at above-mentioned aluminium shot, in seal closure, be connected with inert gas.
The rotary speed of above-mentioned cooling rotating disc is 1～4 rev/min.
The utility model is to prepare the uniform hole of mold bottom by aluminium shot; make in the process of aluminium liquid under the uniform orifice flow of mold bottom after the fusing; form discrete droplet and directly fall into cooling fluid; the simultaneously protection by inert gas; reduce contacting of aluminium liquid and air, can effectively guarantee granularity and the surface-active of aluminium shot.The characteristics such as that the technical program has is simple in structure, efficient is high, production cost is low can be used for suitability for industrialized production high Purity Rare Metals oxide aluminothermic reduction aluminium shot.
Description of drawings
Accompanying drawing 1 is the utility model device structure schematic diagram;
The aluminium shot photo that accompanying drawing 2 is produced for the utility model.
The specific embodiment
As shown in Figure 1, with the aluminium liquid after the fusing of aluminium melting furnace, introducing uniform porose 2 the aluminium shot in bottom by guiding gutter 6 prepares in the mould 1, aluminium liquid prepares hole on the mould by aluminium shot, fall into and be installed in the cooling rotating disc 3 that aluminium shot prepares the mould bottom, high temperature aluminum liquid cools off rapidly by the water that is contained in the cooling usefulness in the cooling rotating disc, cooling off simultaneously rotating disc rotates with 1～4 rev/min speed, making high temperature aluminum liquid form average grain diameter is that 10-15mm, ratio of height to diameter are the aluminium shot about 1:3, after the aluminium shot collection in the cooling rotating disc, it both had been the finished product aluminium shot.
Can regulate as required aluminium shot and prepare the distance between the cooling liquid level in mould bottom surface and the cooling rotating disc, the optional survey of adjusting range is between 50～200mm; For reducing contacting of high temperature aluminum liquid and air, preparing mould 1 and cool off between the rotating disc 3 at aluminium shot seal closure 5 is installed, in seal closure, is connected with inert gas.Cooling rotating disc lower end links to each other with motor 4 by driving-chains such as belt or cog belts, and by the rotation of driven by motor cooling rotating disc, motor selects adjustable speed motor to adjust the rotary speed of cooling rotating disc.
For reducing production costs, the nitrogen with reactive aluminum is surveyed not in the inert gas choosing.
