Embodiment Construction

[0026] As shown in the accompanying drawings: a method for producing fireworks aluminum powder, comprising the following steps:

[0027] The first step is to melt the raw materials, place the aluminum powder raw materials in a vacuum melting furnace, and heat them with a medium-frequency induction heater to fully melt them to form molten aluminum;

[0028] The second step is to atomize and make powder. The melted aluminum melt flows into the atomization chamber through the guide tube, and is atomized by the ultrasonic atomizer in the atomization chamber to fully atomize the aluminum melt. The atomized molten aluminum is cooled by the cooling system to form powder;

[0029] The third step is powder collection. The powder is collected by the powder collection system, and then packaged and packaged after collection.

[0030] Ultrasonic waves are used to atomize the molten aluminum, which effectively improves the effect and efficiency of the atomization. Preferably, the aluminum ...

Abstract

The invention provides a method for producing firework aluminum powder. The method includes the following steps that in the first step, raw materials are molten, wherein the aluminum powder raw materials are placed in a vacuum melting furnace, an intermediate frequency induction heater is used for heating the raw materials, and the raw materials are fully molten to form aluminum melt; in the second step, atomizing is carried out for making powder, wherein the molten aluminum melt flows into an atomization chamber through a flow guide tube, an ultrasonic atomizer in the atomization chamber is used for enabling the aluminum melt to be fully atomized, and the atomized aluminum melt is cooled by a cooling system to form powder; and in the third step, powder collection is carried out, wherein the powder is collected through a powder collection system, and split charging and packing are carried out after collection. By means of the scheme, the atomization effect on the aluminum melt is effectively improved, the uniformity of the powder after atomization is improved, the problem of too large powder is solved, and meanwhile, the production efficiency of the firework aluminum powder is effectively improved.

Description

technical field [0001] The invention relates to the production technology of fireworks aluminum powder, in particular to a method for producing fireworks aluminum powder. Background technique [0002] The pyrotechnic powder of various white tail effects in the combined firework product is to be that main oxidizing agent is prepared with potassium perchlorate now, and when potassium perchlorate is main oxidizing agent, its shortcoming is that cost is high, and its pyrotechnic composition combustion characteristic is that the temperature during combustion is higher, not Produces irregular swaying snowflake effects of aluminum slag, and there is no white snowflake tail combination fireworks yet. Therefore, the proportion of aluminum powder in fireworks is very important. [0003] Patent No. CN104227007B discloses a method for preparing aluminum powder and aluminum alloy by water atomization. The steps are: use a diversion crucible to melt aluminum ingot or aluminum alloy, keep...
