The utility model discloses concrete theory of operation:

when water needs to be filtered, the first valve 14 is opened, the second valve 17 is closed, water flows into the water inlet pipe 12 from the water supply pipe 13, then is sprayed onto the sand bed in the tank body 1 through the rotating disk 11 and the water spraying rod 10, and after filtering through the sand bed, the filter 20 at the bottom of the sand bed is collected, is discharged from the water discharge pipe 19 and flows into the water discharge pipe 16, and flows out through the third valve 18.

When water flow is sprayed to a sand bed in the tank body 1 through the rotating disc 11 and the water spraying rod 10, the water flow reversely pushes the water spraying rod 10 to drive the rotating disc 11 to rotate, so that the rotating disc 11 drives the connecting rod 9 and the deflector rod 8 at the lower end of the connecting rod 9 to rotate, the deflector rod 8 stirs impurities accumulated on the sand bed to fall into the annular groove 5 from the periphery and be collected by the annular groove 5, and the influence on the filtering efficiency due to the excessive accumulation of the impurities on the sand bed can be avoided; since the slag discharging pipe 6 is installed on the side wall of the annular groove 5, impurities in the annular groove 5 are more easily discharged through the slag discharging pipe 6 when back flushing is performed.

When the sand filter needs to be backwashed, the first valve 14 is closed, the second valve 17 and the slag discharge valve 7 are opened, the third valve 18 is closed, water flows into the branch pipe 15 from the water supply pipe 13, then flows back into the tank body from the water discharge pipe 19 through the second valve 17, and sewage is discharged from the annular groove through the slag discharge pipe after the sand bed is backwashed.
