Specifically, the water is swept to the manometer through the water sweeping main pipe 4 of the table that the pump is swept to the efflux table is provided to have certain pressure, the water main pipe 4 is swept to the manometer then is used for the efflux table is swept the pipe 3 and is provided the manometer and sweep water, and finally the table sweeps water and sprays through the efflux hole, thereby realizes the purpose of carrying out the sweeping treatment to the upper surface of filter layer 2.
The pump lift of the jet flow meter sweeping pump can be 15-40m, and the flow can be 30-100m 3/h.
However, the jet meter scanning tube 3 is usually preset, and the included angle between the jet hole and the horizontal plane is usually fixed, which cannot be adjusted during use. In this way, when the upper surface of the filter layer 2 is purged, the middle part area is far away from the jet flow meter-sweeping pipe 3, so that the meter-sweeping water pressure at the position is small, and the purging cannot be performed in time, which may cause that a large amount of impurities are accumulated in the middle part; or the surface sweeping water is located in a partial area right below the jet flow surface sweeping pipe 3, so that the surface sweeping water cannot be swept, and partial impurities can be accumulated after long-term use.

The pressure gauge water sweeping main pipe 4 and the jet flow gauge water sweeping pipe 3 can be connected through a hose, and therefore the jet flow gauge water sweeping pipe 3 is not affected when being rotated.
The rotating disc 705 is usually large in size, so that the rotating precision of the rotating disc is convenient to control, excessive rotation is prevented, and the rotating angle of the jet meter scanning tube 3 cannot be accurately controlled.
The rotating disc 705 can be marked with a graduated scale, so that a worker can observe the rotating amplitude conveniently and accurately adjust the spraying direction of the surface sweeping water.
Wherein, the height difference between the jet flow surface scanning tube 3 and the upper surface of the filter layer 2 can be 550mm. In other embodiments, the height of the jet meter-sweeping tube 3 may be adjusted according to the actual situation by combining the angle between the direction of the jet hole and the horizontal plane.
