Mixing material-moisturizing granulation process for gunpowder

Abstract

The invention discloses a mixing material-moisturizing granulation process for gunpowder. The process particularly uses equipment such as a material preparing system, a mixing machine, a material moisturizing tank, a granulator, a belt and a control system for mixing and granulating of the gunpowder. The process provided by the invention adopts mechanized operation, material preparing, mixing, material moisturizing, granulation and sieving are integrated, and the problems of long working process time, a complicated working process, a large unit medicine addition amount (a single mixing amountis too large to facilitate production safety), uniform mixing and the like are solved; when materials are prepared, a plurality of raw material hoppers are used to put materials into to a material preparing hopper, so that the problems of a plurality of times of manual weighing and personnel health are solved; no friction occurs during mixing, material adding and discharge are performed in a sealmanner, so that the problems of heating, friction, dust rising and the like are solved; and a material moisturizing machine adopts a concentric shaft to drive the material moisturizing tank to turn over up and down and stir, and stirring is performed in a non-central-shaft manner, so that the problems that materials are bonded to a central shaft and the material moisturizing tank are solved, and the labor intensity is reduced.

Description

technical field [0001] The invention relates to the technical field of gunpowder granulation, in particular to a granulation process of pyrotechnic powder mixed tidal material. Background technique [0002] Gunpowder, as the name suggests, is a chemical that can be caused to burn violently by sparks, flames, etc. According to the records of "Fan Zi Ye Li", it has been used in folk livelihood applications in China during the Spring and Autumn Period. Gunpowder is one of the four great inventions of China. Under the action of appropriate external energy, gunpowder itself can burn rapidly and regularly, and at the same time generate a large amount of high-temperature gas. In the military, it is mainly used as the propellant of bullets, artillery shells, propellant of rockets, missiles and other driving devices. It is an important part of ammunition and an outstanding achievement in the history of human civilization. Gunpowder is one of the important inventions of human civili...

Problems solved by technology

This manual mixing method has long mixing time and large dust, which is unfavorable to production safety and unnecessary waste; at the same time, the working environment of the staff is harsh, the labor intensity and danger are high, the process is complicated, and the contact between tools and materials is not easy to control. , easy to produce unsafe friction; and it is difficult to reach the same value for the moisture and mixing uniformity of the finished product wetted by different people at different times
