Title:
OVERFLOW PIPING OF STORAGE TANK FOR WET BLAST AND RECTIFICATION MODULE OF OVERFLOW PIPING
Document Type and Number:
Japanese Patent JP2019107735
Kind Code:
A
Abstract:
To suppress reduction in abrasive grain concentration of slurry inside a storage tank.SOLUTION: A overflow piping 20 is provided with a drain pipe 26 which is provided in a storage tank for storing slurry for wet blast and has an exhaust port 27 with an upward opening at an upper end part, and a rectification member 28 which surrounds the lower region at least from the exhaust port 27 out of the outer periphery of the upper end of a drain pipe 26. The slurry moves up from the lower end of the rectification member 28 and inside a rectification space 32 between the outer periphery of the drain pipe 26 and the inner periphery of the rectification member 28, and then goes toward the exhaust port 27. The slurry is rectified inside the rectification space 32, so that the abrasive grain in the slurry is settled and therefore the amount of abrasive grain to be discharged from the exhaust port 27 is reduced.SELECTED DRAWING: Figure 3
