Abstract

PURPOSE:To attain forceful suction, transport and injection of granules, particles, liquid or gas by defining a large negative pressure area in an expansion chamber formed around the outer periphery of the edge opening of a transport line. CONSTITUTION:A transport line 1 has around its edge opening an expansion chamber 2 of a large capacity which defines a large negative pressure area. High pressure air is introduced through a high pressure air inlet line 3, temporarily received in a high pressure air receiving chamber 4, and then injected through a nozzle 5 formed by an annular slit between the receiving chamber 4 and the expansion chamber 2. The injection speed obtainable at the nozzle becomes locally about sound velocity, and the negative pressure prevailing in the large space area defined by the expansion chamber 2 causes ballast in a tank at the ship bottom to be forcefully sucked up through a tank drain port 9 and the transport line 1.

Connect. At this time, the height of 4 m is achieved using the hydraulic jack of the table lift vehicle (8). After that, high pressure exchange heat is sent from the Takasho air pipe (3) to the high pressure air pre-chamber (
4) The same pressure air is temporarily stored in the chamber (4) and the expansion chamber (2).
It is ejected from a nozzle (5) formed from the same annular slit. The ejection speed from the same Nosuru is 1st in the local sound chain! IM
The wide open area of the enlarged chamber (21 yen) is kept under negative pressure, and the paralast of the bottom tank (6) is suctioned to 1 force through the tank drain hole (9) and the transportation mound (1). The air is mixed with the air from the nozzle (5), and then the diffuser (
7) to smoothly transport the ballast water to the air ratio and discharge it from the mixed liquid discharge port 4.
