Title:
MULTIPLE BLAST DEVICE
Document Type and Number:
Japanese Patent JP2014180717
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a direct pressure type multiple blast device capable of blowing from an outflow nozzle without a pressure loss while preventing the occurrence of a bridge phenomenon by properly mixing a blast material and gas, and capable of recovering pressure by applying a constant amount of back pressure in T-tube, in the present invention.SOLUTION: Air is directly supplied to a vertical cylindrical pipe 12 with a plurality of constant interval or random through-holes 10 existing in a pressure tank 1 and an outflow nozzle 2 installed on the lower outside of the pressure tank 1 from the inside of the pressure tank 1 by a booster nozzle pipe 19, and the pressure-recovery effect is also provided by applying the back pressure to the pressure tank side by colliding compressed air with a gas-liquid mixed fluid (such as the blast material) of a main pipe 21 of the T-tube 4 by an auxiliary pipe 23, and a jet flow can be made.
