Abstract

The invention discloses an automatic gelatin waste water drossing device applied to a gas floatation clarifier. The automatic gelatin waste water drossing device comprises the drossing device and an effluent liquid level adjusting weir plate of the gas floatation clarifier, a dross thickness measuring instrument arranged in a gas floatation pond, and an external controller. The dross thickness measuring instrument, an effluent liquid level adjusting weir plate adjusting mechanism of the gas floatation clarifier and a drossing device driving mechanism of the gas floatation clarifier are all connected with the external controller. The dross thickness measuring instrument is adopted for measuring the thickness of dross in the gas floatation clarifier, then the controller automatically adjusts the height of the effluent liquid level adjusting weir plate and the running speed, starting and stopping of a drossing machine according to thickness information, and it is avoided that the dross overflows out through the weir plate. When the thickness of the dross is reduced to a certain degree, the height of the weir plate is reduced through the controller, the running speed of the drossing device is decreased, or the drossing device is intermittently started, therefore, the dross is reasonably removed, the running efficiency of the drossing device is improved, the drossing device runs more effectively and reasonably, it is avoided that the drossing device runs in an idle mode, and the aim of energy saving and consumption reducing during daily running of a system is achieved.

Description

[0001] technical field [0002] The invention relates to the field of air flotation machines, in particular to an automatic skimming device for gelatin wastewater applied to air flotation machines. Background technique [0003] The conventional air flotation machine includes an air flotation tank, an air-dissolving device, a skimming device and a liquid level adjustment tank. By adding flocculants and coagulants, the COD\BOD and a small amount of N\P plasma dissolved in the air flotation tank are formed into a suspension. The highly dispersed micro-bubbles produced by the air-dissolving device will float the suspended matter on the water surface, and the suspended matter will be concentrated in the central cylinder through the skimming device and discharged, and the treated clean water will be discharged from the liquid level adjustment tank. The disadvantage of the existing air flotation machine is that: the gelatin wastewater has a lot of scum and is light, and it is not...
