Abstract

The invention discloses a nitrocotton absorption agent mass or block crushing device comprising a frame. A vertical agent box is arranged on the frame. A motor is arranged on the frame on one side of the agent box. A hopper is arranged on the top of the agent box. A discharge port is arranged on the bottom of the agent box. Three levels of crushing mechanisms are sequentially arranged from top to bottom in the agent box. Each level of crushing mechanism is formed by two teeth-type tearing rods arranged in parallel and on a same height. Spaces are arranged between the largest outer diameters of the two tearing rods of the first level of crushing mechanism and the second level of crushing mechanism. The three levels of crushing mechanisms are driven by motors. With the device provided by the invention, defects of non-uniform nitrocotton particle size, high risk degree, intensive labor, low working efficiency, and the like of existing nitrocotton absorption agent mass or block crushing processes. With the device, continuous crushing and human-machine isolation are realized. The process is simple and reliable, and the procedure is safe. The obtained absorption agent particles are uniform, and can be directly applied in subsequent processes.

Description

technical field [0001] The invention relates to a crushing device for absorbing drug clusters or lumps of nitrocellulose, which is the main raw material for the preparation of double-base propellants, and is mainly used for the manufacture of double-base propellants and the crushing of nitrocellulose pyrotechnic products. Background technique [0002] The double-base propellant is mainly formed by extruding and casting processes after adjusting the formulation of nitrocellulose absorbent. The preparation process of the nitrocellulose absorbent is to disperse the nitrocellulose into water to form a slurry, then add nitroglycerin, fully absorb the nitroglycerin into the nitrocellulose fiber through sufficient stirring and mixing, and then centrifugally drive water to form the nitrocellulose absorbent. In order to ensure the safety of nitrocellulose absorbent during transportation and use, about 30% of water is usually reserved in it, so it is slightly viscous, and it will be b...
