Abstract: A floating sludge discharge device for a square settling tank, and belongs to the field of water treatment. In order to solve the problem of scraping of floating sludge in the square settling tank, by disposing a water outlet hole below a liquid level and designing a pulling barrel mechanism that changes its overall gravity by using secondary settlement water, to move up and down to pull a sludge scraping plate to move back and forth, the stretching-out end of the sludge scraping plate of a sludge scraping plate mechanism automatically goes deep into the liquid level and automatically lifts up when it returns.

Abstract: An automatic draining device for condensed water or leaking water in an aeration pipeline comprises a water tank, a draining and exhausting stand pipe and a float bowl valve. According to the automatic draining device, the condensed water or the leaking water is sprayed out through pressurized air; under the condition that the condensed water or the leaking water in the aeration pipeline is basically drained, the outlet is basically closed, only allowing little gas to flow out; and meanwhile, when water is accumulated in the pipeline, the water outlet can be automatically opened widely to drain the accumulated water rapidly.
