A gunpowder drying equipment

Abstract

The invention discloses equipment for drying pyrotechnic composition. The equipment is characterized by comprising a drying module (1), a screening module (2), an air suction module (3), a front support and speed-regulation module (4), a rear support module (5) and an electric cabinet (6). Steam or hot water enters a heating pipe of the drying module to heat the inside of the drying module; after entering the drying module from a rear end inlet of the drying module, the pyrotechnic composition moves towards the front end gradually under the action of rotation at a horizontal inclination angle, and when the pyrotechnic composition passes through the screening module at the front end, grains are separated from composition in the rolling process. The screening module is in serial connection with the front end of the drying module. An air suction pipe of the air suction module is fixed in the center of the drying module to suck away hot air and dust which are generated in the drying module and collect the hot air and the dust through a water washing system, and the safety is guaranteed. The front and rear support modules support the drying module, power is provided by a speed-regulation motor of the front support module, and the drying module is driven by a guide wheel to rotate. The equipment solves the problem of drying of grains in a wet granulation method for the pyrotechnic composition. The equipment has the characteristics of safety, environment friendliness and high efficiency.

Description

technical field [0001] The invention relates to a gunpowder drying equipment, which is used for drying gunpowder such as fireworks and firecrackers. Background technique [0002] At present, China has more than 6,000 fireworks and firecrackers manufacturers, most of which are still using traditional gunpowder—military gunpowder. Due to the large amount of gunpowder used in a single firework product, a large amount of smoke will be generated when it is set off, which has caused great harm to the environment. The impact of it is no longer suitable for the requirements of modern products. At the same time, due to the complex manufacturing process of traditional gunpowder (including gunpowder single sieve, powder mixing, granulation, drying, etc.), especially the drying production line, most of them adopt natural drying or hot air drying, which has long production lines, long time required, Occupying a large space, employing a lot of labor, low efficiency, poor safety, low degr...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a kind of gunpowder drying equipment aiming at the deficiencies in the prior art, which uses the rotating drying equipment to dry the wet gunpowder granules produced by the gunpowder automatic granulator, which overcomes the need for natural drying or hot air drying. Defects such as long time required, long distance, large site, unenvironmental protection, and unsafety
