The invention discloses a two-chamber debris recovery experimental device for the impact crushing research of active materials, which comprises a two-stage box body, a target plate and two pieces of soft rubber sheets. Box partition, front-stage box plate, upper movable cover plate, box bottom plate and two box side plates; rear-stage box plate, front-stage box plate, box bottom plate and two box side plates are common It constitutes a box without a cover, and the two-stage box partitions are parallel to the rear box plate and the front box plate and are fixed in the box without a cover; the upper movable cover is set on the top surface of the box without a cover; the front box There is a fragment incident hole in the center of the body plate, and there are two-stage box connection holes in the center of the two-stage box partition. The hard steel plate is fixed in the center of the back-stage box plate and is located in the back-stage box. Two soft rubber sheets are fixed. On the partition of the two-stage cabinet, and cover the connection holes of the two-stage cabinet. The invention solves the problem that the fragments of the active material cannot be effectively recovered after impact crushing.
Description
technical field [0001] The invention belongs to the field of material impact crushing research, and in particular relates to a two-chamber debris recovery experimental device for active material impact crushing research. Background technique [0002] Combustion (or oxidation) reaction and release of energy under impact conditions are important properties of combustion-type active materials, and the degree of reaction depends on the degree of fragmentation of the material. After dynamic impact loading, observation of material fragmentation and statistics of recovered material fragments are crucial to the research on the reaction of combustion-type active materials, and can provide a basis for the reaction efficiency and formula design of combustion-type active materials. At present, gelatin recovery method, water tank recovery method and metal box recovery method are usually used for fragment recovery methods. However, the disadvantages of these recycling methods are as foll...
