A fireworks pyrotechnic powder granulator

Abstract

The invention discloses a fireworks pyrotechnic powder granulator. The lower part of the hopper is connected to a granulation chamber, and the granulation chamber is provided with a rotating pressing blade and a rotating squeezing blade stacked up and down. The rotating pressing blade and the rotating squeezing blade The direction of rotation is opposite, and the side wall of the granulation chamber surrounding the rotating extrusion blade is composed of an annular screen, the outer edge of the rotating extrusion blade is close to the annular screen, and a collection mechanism is arranged outside the annular screen. The equipment is suitable for wet granulation, and its safety performance is guaranteed; the land used for the equipment does not exceed 30 square meters, the overall investment does not exceed 60,000 yuan, and the output per day (8 hours) reaches 5 tons, with low investment and high production efficiency; High particle forming rate.

Description

technical field [0001] The invention relates to a granulation device for pyrotechnic powder used in fireworks. Background technique [0002] In the prior art, after the ingredients of fireworks and pyrotechnics are pulverized by ball milling, stirred and mixed evenly, the working process of the granulation equipment is: steam steaming, compacting with an oil press, cooling, slicing, stripping, granulating, drying, and polishing made. The process is cumbersome, the efficiency is low, and the investment is huge. The production line covering an area of ​​800 mu and investing tens of millions of dollars can produce no more than 5 tons per day (8 hours). [0003] There are also other forms of granulation, such as spherical granulator granulation and then vibrating screening; tablet granulation and sorting, etc., but there are disadvantages such as low granulation rate and large safety hazards. Contents of the invention [0004] In order to solve the above disadvantages, the t...
