Abstract
PURPOSE: To improve fluidty of low slump poor mixture slurry, and obtain smooth transportation by feeding air intermittently to the suction side of an elastic tube.
CONSTITUTION: When a shaft 5 is rotated, squeezing rollers 7 are rotated around the shaft 5 to generate negative pressure to the suction side X of the elastic tube 4. The solenoid valve 10 performs open and close operation with the opening and closing time preset by dials 9a, 9b of the timer 9, therefore, air is intermittently suctioned to the suction side X from air inducing pipe 8. Simultaneously with this, slurry S stored in the hopper 1 is induced to the suction side X through the duct 2. Therefore, slurry scatteredly mixed with bubble B is induced to the suction side X of the tube 4, and the fludity of low slump poor mixture slurry S is improved by decreasing the volume of the bubble B by pressuring the squeezing roller 7, resulting to ease the movement of the slurry S.
