Water is supplied from the water supply chamber 5 in a film form. This water supply chamber 5 is provided with a partition plate 6 that divides the water supply chamber 5 into two front and rear chambers 5a and 5b, leaving an upper space A inside.
The water supply pipe 7 is connected to the rear chamber 5b, and the front chamber 5
An outflow port 8 is provided at the front lower part of a, and water is supplied from the outflow port 8 onto the inclined plate 3 in the form of a film. The outlet 8 is provided with an adjustment plate 9 whose position can be adjusted up and down, and the adjustment plate 9 adjusts the thickness of the water film. The width of the outflow port 8 was widened to eliminate the clogging. In addition, 10 in the drawing is the inclined plate 3
The discharge port 11 on the lower end side is a tightening bolt that adjustably tightens the adjustment plate 9.
