The pipe diameters of the first horizontal pipe, the second horizontal pipe, the third horizontal pipe and the vertical pipeline are DN100mm-DN150 mm.

And the vertical distance among the three horizontal pipelines of the first horizontal pipe, the second horizontal pipe and the third horizontal pipe is kept between 10cm and 15 cm.

The uppermost horizontal pipe in the three horizontal pipelines of the first horizontal pipe, the second horizontal pipe and the third horizontal pipe is 10cm lower than the liquid level of the conditioning tank.

The utility model discloses the beneficial effect who brings: the utility model discloses simple structure, practicality are strong, the batch production of being convenient for, convenient to use moreover. The problem of the unable emission of mud supernatant after conditioning the stand is solved, according to the supernatant layer thickness of difference, set up three emission liquid level moreover, improved and discharged the effect, the practicality is stronger.
