Full-automatic forming unit for dry powder of pyrotechnic composition

Abstract

The invention discloses a full-automatic forming unit for dry powder of a pyrotechnic composition. According to the invention, a partition plate 6 is arranged on a main machine base 17; a die frame 7,an upper punch 10, a female die 11, a lower punch 18, a shuttle groove 12, a trolley 15 and a second shielding door 13 are arranged at one side of the partition plate; and a first shielding door 4, astorage hopper 3, a ball valve 2, a material box 22 and angle iron 29 are arranged at the other side of the partition plate 6. Wet powder obtained after slurrying of pyrotechnic composition powder isproperly dried into dry powder; the characteristics of good fluidity and no mold sticking of the dry powder are utilized; automatic compression molding is carried out in a hydraulic mode in a die; formed particles do not need to be baked any more and can be directly wrapped with powder for use; the automation degree of equipment is high; complete man-machine separation is achieved; safety and reliability are achieved; sanitary conditions are good; high economical performance is obtained; and the setting-off effect of a prepared pyrotechnic composition is good; and conditions are created for realizing workshop production of the pyrotechnic composition and saving land occupation area.

Description

Technical field [0001] The invention relates to a powder forming unit, in particular to a fully automatic forming unit for flammable and explosive pyrotechnic powder dry powder. Background technique [0002] In the production of fireworks, the pyrotechnic powder needs to be formed into particles. There are two current forming methods. The smaller particle size is driven by the rotation of the drum to drive the inner core of the drum to roll and gradually bond and grow. The larger particle size is formed on the pressure device with a mold. The powders of the two methods are formed in a wet state. The wet powder is very viscous. The entire forming process cannot be separated from manual labor. The sanitary conditions are poor and there are serious safety hazards, which violate the safety regulations of "man-machine separation". The formed wet products have to be dried in a drying room for a long time, which not only consumes a lot of energy, but is also a huge source of danger. T...

AI Technical Summary

Problems solved by technology

The powder materials of the two methods are molded in a wet state, and the wet powder is extremely viscous. The entire molding process is inseparable from manual labor. The sanitary conditions are poor, and there are serious safety hazards, which violate the safety regulations of "separation of man and machine". The formed wet products have to be dried in a drying room for a long time, which not only consumes a lot of energy, but is also a huge source of danger

The produced products are loose in texture, low in quality and poor in discharge effect

Due to the lack of safety guarantees, in order to prevent suicide and explosion, the production layout had to be scattered and occupy hilltops, consuming a lot of land and resources
