Technical Field

The invention relates to the technical field of aluminum bean preparation, in particular to a pneumatic non-contact type preparation device capable of improving the purity and activity of aluminum beans.

Background

The aluminum beans are aluminum particle products in the shape of go pieces, the high-purity high-activity aluminum beans are used as a high-efficiency metallurgical reducing agent and widely applied to the aspect of aluminothermic reduction of high-purity rare metal oxides, such as preparation of high-purity metals such as tantalum, niobium, titanium and the like, the granularity and the activity of the aluminum beans are important parameters for determining the effect of reducing and removing impurities in the fine metallurgy process, the smaller the average granularity is, the higher the surface activity is, the better the reduction reaction is, the better the impurity removal effect is, and finally, the high-purity active metals can be obtained.

The method for preparing the aluminum beans at present is mainly a mechanical method, the approximate process is that the aluminum melt flows out from a small hole to a small rotating disc which is obliquely arranged, the aluminum melt is divided into semi-solidified aluminum beans which are different in size and approximate to a ball shape by the rotating disc, then the primarily formed aluminum beans roll into the rotating disc with the oblique arrangement, and finally the aluminum beans are cooled and formed.

Although the method is widely used, a screening mechanism is obviously lacked, aluminum beans with different sizes are mixed together, the secondary processing and sorting are not facilitated, in addition, on one hand, the method exposes the aluminum beans in the air, so that the aluminum and the air generate natural oxidation reaction, the oxygen concentration is difficult to control, the oxidation is not uniform, the activity of the aluminum beans is reduced, on the other hand, when the aluminum beans are in a semi-solidified state, the surfaces of the aluminum beans have certain adhesion, and the aluminum beans are brought in by contacting with some metal surfaces, so that the purity of the aluminum beans is reduced, and therefore, a pneumatic non-contact type preparation device capable of improving the purity and the activity of the aluminum beans is produced.

Disclosure of Invention

In order to realize the purposes of classifying the aluminum beans with different sizes and improving the purity and the activity of the aluminum beans, the invention provides the following technical scheme: the utility model provides a can improve pneumatic non-contact preparation facilities of aluminium beans purity and activity, includes the support frame, the inside fixedly connected with pneumatic mechanism of support frame, the blanking mouth has been seted up at the top of support frame, and the fixed surface of blanking mouth is connected with the passageway of blowing, pneumatic mechanism includes the casing, the inside diapire swing joint of casing has screening mechanism, the inside of casing and the equal fixedly connected with storing groove in both sides that is located screening mechanism, the upper portion fixedly connected with cavity passageway in storing groove, the equal gas port of one end fixedly connected with in storing groove is kept away from to the cavity passageway, and the one end and the passageway fixed connection of blowing of cavity passageway are kept away from to equal gas port.

The invention has the beneficial effects that:

1. the semi-solidified aluminum beans that will be divided drop to the screening mechanism through the blanking mouth on, because the blanking mouth surface is provided with the passageway of blowing, and be provided with a plurality of hierarchical layers and the mouth of blowing in the passageway of blowing, it is the pure oxygen to blow the passageway of blowing, and make the gas flow rate that the left and right sides blew out the same, make aluminium react at the in-process of whereabouts and pure oxygen, and evenly form the protective layer rapidly on its surface, thereby reached the active effect of improvement aluminum beans, because the semi-solidified aluminum beans just accomplished the cooling oxidation process at the in-process of whereabouts, so its surface loses the adhesion, thereby reach the effect that improves the aluminum beans purity.

2. In the process that the aluminum beans fall in the air blowing channel, because the air blown out from two sides has the same flow velocity, when the blown aluminum beans are in an irregular shape, the aluminum beans can deviate towards one side to temporarily block the air blowing opening on one side, so that the flow velocity of the air blown out from two sides is not the same, the other end of the air blowing channel is connected with the screening mechanism, the change of the flow velocity of the air in the air blowing channel can cause the change of the flow velocity of the air in the rotating shaft of the screening mechanism, therefore, the rotating shaft deflects, the central line of the double-shaped plate is not aligned with the central line of the air blowing channel, so that the irregular aluminum beans fall on the right side of the double-shaped plate and fall into the storage groove on the right side, otherwise, when the shape of the aluminum beans is more regular, the aluminum beans fall into the middle of the double-shaped plate, the flow velocity of the air blown out from, reach the effect of screening classification to the aluminium beans.

Preferably, the screening mechanism comprises a rotating shaft, a shaft sleeve is sleeved on the surface of the rotating shaft, and a material distributing mechanism is fixedly connected to the surface of the shaft sleeve.

Preferably, the material distribution mechanism comprises a double-shaped plate, the interior of the double-shaped plate is fixedly connected with an air supply channel, and the surface of the air supply channel is fixedly connected with a U-shaped air nozzle.

Preferably, one end of the hollow channel, which is far away from the air homogenizing port, is fixedly connected with the screening mechanism.

Preferably, the surface of the double-shaped plate is in a design shape with a high middle and two low sides, and the U-shaped air nozzle is positioned at the center of the double-shaped plate.

Preferably, an air supply channel is formed in the rotating shaft.

Preferably, the interior of the air blowing channel is fixedly connected with a grading layer, and the surface of the grading layer is provided with an air blowing opening.

Preferably, the U-shaped air nozzle is provided with three air nozzles, and air blown out by the air nozzles forms a U-shaped air flow.
