Problems solved by technology

But its main disadvantage is that although some equipment still use sieving as a pre-mixing process, the existing mechanical equipment has given up the mixing method of sieving as a means, sieving and integration, and has lost or partially lost the above-mentioned advantages of the traditional process. Advantages; at the same time, the working mechanism of the existing pyrotechnic equipment is in direct contact with the pyrotechnic drug and rotates or vibrates to generate heat and conduct it to the pyrotechnic drug, forming a safety hazard

Abstract

The invention discloses a firework powder automatic screening and a device. A screen net is arranged in a sealed powder mixing container of the device and performs circle rotation and overturning. A seal type mechanical automatic mixing method can improve production efficiency and avoids dust environment pollution and occupation disease harm, automatic control and remote control can be achieved to perform human-machine separation, and personal injury is completely avoided. Movement of the screen net and firework powders accords with manual screening mixing, a mixing method is mild, and no movement heat-producing part is arranged in the powder mixing container. Compared with other mixing methods, the possibilities that the firework powders are triggered are small, the powder is evenly mixed, powder mixing quality is good, screen nets of different meshes are matched according to particle size of the firework powder to achieve different screening and mixing effects, different performance requirements of the firework powders are met, and impurities and caking possibly existing in the powders can be further discharged. The device is simple and convenient to maintain, and flow is concise.

Description

Technical field [0001] The invention relates to a pyrotechnic drug mixing device for fireworks and firecrackers. Background technique [0002] In the production of fireworks and firecrackers, the process of mixing pyrotechnic drugs is the most dangerous process, and it is also a key basic process that determines product quality. The traditional process adopts manual sieving. First, various powdered raw materials are mixed in proportion, and the prepared materials are placed in the sieve tray. The worker holds the sieve tray and pushes its circumference to make the medicine fall, and the sifted medicine falls into the container below , By sieving the pyrotechnic drug as a means to make various raw materials uniformly mixed. Its advantages are mainly: 1. As a summary of hundreds of years of historical experience and lessons, this kind of mixing method is relatively mild, and compared with other mixing methods, it is less likely to trigger pyrotechnic drugs; 2. The mixing is unifor...
