Drying device for gunpowder

Abstract

The invention relates to a drying device for gunpowder. The drying device comprises a drying cylinder, a screening device, an exhaust device, a front supporting assembly, a rear supporting assembly, two guide rails and an electric control box. The drying cylinder comprises an outer cylinder body, an inner cylinder body, a spiral heating pipe, a front cover plate, a rear cover plate and a rotating valve. The spiral heating pipe is located between the inner cylinder body and the outer cylinder body. The front cover plate and the rear cover plate are used for sealing the front end and the tail end of the drying cylinder respectively. The rotating valve is communicated with the spiral heating pipe through fluid. The screening device is located at the tail end of the drying cylinder and is connected with the inner cylinder body. The exhaust device comprises an exhaust pipe. One end of the exhaust pipe stretches in the inner cylinder body. The two guide rails are arranged on the periphery of the outer cylinder body in a sleeving manner and are fixed to the front supporting assembly and the rear supporting assembly respectively. The drying cylinder rotates under the guidance of the two guide rails. The electric control box is electrically connected with the drying cylinder, the screening device, the exhaust device and the rear supporting assembly. According to the drying device for gunpowder, the drying problem of tablets prepared through wet granulation can be effectively solved, and the drying device for gunpowder has the beneficial effects of being efficient, environmentally friendly, safe, capable of saving labor, extensive in use and the like.

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
