Gun propellant mixing and extruding device

Abstract

The invention discloses a gun propellant mixing and extruding device, which comprises a motor, a conic reducer, a main reducing gear, a connecting device, a feeding machine barrel, a sealing machine barrel, a gas exhauster barrel and an explosion venting machine barrel, wherein the motor is connected with the conic reducer through a coupler and a wall penetration shaft; the conic reducer is connected with the main reducing gear through the coupler; the main reducing gear is connected with a connecting device; the connecting device is connected with the feeding machine barrel; the feeding machine barrel is connected with the sealing machine barrel; the sealing machine barrel is connected with the gas exhauster barrel; the gas exhauster barrel is connected with the explosion venting machine barrel; and the sealing machine barrel is internally provided with a co-rotating twin screw. With the adoption of the gun propellant mixing and extruding device, the intermittent mixing of a gun propellant extruder is changed into the continuous mixing, and the gun propellant extruder is in enclosed environment when in processing, thus greatly improving the production efficiency and the quality of products; and the gun propellant mixing and extruding device is good in self-cleaning property, so that residence time distribution range of materials in the gun propellant mixing and extruding device is narrower, and the mixing is uniform.

Description

technical field [0001] The invention relates to a propellant mixing and extruding device. Background technique [0002] The raw material of the propellant is high-mesh powder, which requires high mixing effect, high risk, and difficult processing. At present, most of the equipment in operation is a double-rotor kneader, and the double-rotor kneader operates intermittently. , the mixing effect on the propellant is general, so that the output and quality of the propellant are greatly limited. Contents of the invention [0003] The object of the present invention is to provide a propellant mixing and extruding device with high production efficiency and good self-cleaning property. [0004] The technical solution adopted by the present invention to achieve the above purpose is: a propellant mixing and extruding device, including a motor (1), a bevel gear reducer (2), a main reducer (3), a connecting device (4), Feeding cylinder (5), sealing cylinder (6), exhaust cylinder (7)...
