PURPOSE:To increase the water pressure applied to the laver screen and to improve the efficiency of washing the foreign matter, by jetting a large quantity of water from above and below with a low-pressure pump of large discharge. CONSTITUTION:The rollers 2, 2' and 3, 3' for transferring the laver screen 12 are set at both ends of the frame 1; the perforated water pipes 4 and 4' connected to the low-pressure pump 6 of large discharge, above and below the screen between the rollers. The screen 12 is passed through the pipes by the rotation of the rollers, and washed efficiently by a large quantity of water jetted from the pipes 4 and 4' without atomizing. The splashed water is received by the detachable curtain 9, and the residue is removed. The foreign matter is dropped to the slanted strainers 10 and 10' at the top of the water storage tank 8.
