DISPERSIBLE POWDER CHARGE AND POWDER CHARGE DISPERSING APPARATUS Russian patent published in 1999 - IPC

FIELD: powdered material dispersing equipment. SUBSTANCE: dispersible gas-and-powder charge containing non-combustible and active components is made multilayer, with alternate arrangement of non-combustible and active components, with heavy components being used as non-combustible components and light components being used as active components. Apparatus for explosive dispersion of powder charge has multibarreled cassette with shock-absorbers, ejection charge, ignitor and dispersible powder charge positioned in container and put onto each barrel. Ejection charge and dispersible powder charge are disposed in two readily destructible containers, respectively. Dispersible powder charge is made multilayer and contains heavy and light components, each positioned in individual enclosure. Cassette has torque link damper system with shock-absorbers mounted on each barrel, and at least two hydraulic compensators positioned symmetrically on cassette. Such composition allows gas-and-powder charge with increased dispersion distance to be produced, and construction of apparatus provides effective dispersion of materials on vast areas due to high discharge power and increased distance of spreading of gas-dispersion flow by reduced recoil force. EFFECT: increased efficiency and enhanced reliability in operation. 7 cl, 2 dwg
