The present invention discloses an immersed active infrared self-cleaning secondary sedimentation tank sludge blanket induction device and an application method thereof, the induction device comprises an upper sleeve and a lower sleeve that are connected up and down and form a communicated inner cavity, a set of infrared emitters and infrared receivers that are located on an inner wall of the upper sleeve and are oppositely arranged, a transparent hard ring that is annularly adhered to front sides of the infrared emitters and the infrared receivers, and a push rod assembly that can move up and down in the inner cavity and is used for cleaning the transparent hard ring; wherein a sludge outlet hole and a water outlet hole located below the sludge outlet hole are arranged on the upper sleeve, a bearing plate is arranged in the inner cavity of the lower sleeve.

Immersed active infrared self-cleaning secondary sedimentation tank sludge blanket induction device and application method thereof

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.

Floating sludge discharge device for square settling tank

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.
