The transfer pipe 300 includes a suction port 310, a mixing chamber 330, and a discharge port 350. Here, the mixing chamber 330 refers to a region of the transfer pipe in which the high pressure water and / or air introduced from the high pressure water supply unit 100 and the transfer object introduced through the suction port 310 of the transfer pipe 300 are mixed. Therefore, it is apparent that the high-pressure water supply unit 100 according to the present invention is provided between the suction port 310 and the discharge port 330 of the transfer pipe.

In the high pressure water supply unit 100 of the present invention, a jet pump is generally used. Jet pump, also called injection pump or fractionation pump, pumps high-speed, high-pressure driving fluid with high energy into the conveying pipe to deliver the conveying fluid from the relatively low pressure inlet. It refers to a pump that is sent to the discharge port together with a high pressure driving fluid. Since the high speed drive fluid should suck the relatively low speed transfer fluid, the efficiency is inferior to that of the general pump, but there is no moving part and the structure is simple, which can be usefully used in the present invention.

The jet pump has a center-drive jet pump in which the driving fluid is ejected through the injection nozzle disposed at the center of the conveying pipe and an annular shape in which the driving fluid is ejected through the injection nozzle disposed at the periphery of the conveying pipe. It is classified as an annular-drive jet pump. Both the centralized jet pump and the annular jet pump can be used for the high-pressure water supply unit of the present invention.
