An automatic feeding device for preparing shell propellant

Abstract

The invention relates to manufacturing technological equipment of projectile propellant, particularly to an automatic feeding device for projectile propellant preparation. The automatic feeding device comprises an elevator, a rotary discharge device, a discharge spreading device, a kneading device, a solvent conveying device, a smashing and conveying device and a sieving barrel, wherein the rotary discharge device, the solvent conveying device and the smashing and conveying device are distributed on the outer side of the kneading device in the circumferential direction; the discharge spreading device is arranged between the rotary discharge device and the kneading device, and is fixedly connected with the kneading device; the elevator is positioned on one side of the rotary discharge device, and is used for providing materials for the rotary discharge device; the smashing and conveying device is connected with the sieving barrel. According to the automatic feeding device, the kneading plasticizing of main components such as nitrocotton and auxiliary materials such as a solvent and a plasticizer is achieved, the material subjected to gelling is divided into a plurality of parts, and the divided material is transported into the sieving barrel to be subjected to the follow-up companding forming procedure.

Description

technical field [0001] The invention relates to a manufacturing process equipment for the propellant of a cannonball, in particular to an automatic feeding device for preparing the propellant of a cannonball. Background technique [0002] At present, the production of artillery shells and propellants in our country adopts the production mode of manual plus special planes, and no unmanned automation has been realized. This traditional manufacturing of propellants is done manually, which is not only inefficient but also the quality cannot be guaranteed. More importantly, it faces a huge threat to personal safety in the face of flammable and explosive ammunition. [0003] There is no automatic kneading, plasticizing and crushing device for solid and liquid raw materials used in the manufacture of propellant propellants in our country. Raw materials for propellant propellants are flammable and explosive in high-temperature and high-pressure environments, and the safety requireme...
