As shown in fig. 1, the present embodiment provides a filtration system including a drive module, a filtration cylinder 15 in which a filter material 17 for filtering a water flow to be filtered to form a filtered water flow is provided, a first valve body 1, a second valve body 2, a third valve body 3, a fourth valve body 4, a fifth valve body 5, a sixth valve body 6, and a seventh valve body 7. The driving module is disposed between the filtering cylinder 15 and a preset first area for storing the water flow to be filtered, so as to drive the water flow to be filtered or the cleaning water flow to flow into the filtering cylinder 15. In other embodiments, the filter material 17 may be composed of a first filter layer, a second filter layer, and a third filter layer (not shown) that are sequentially densified from bottom to top.

Specifically, the first pipe 11, the second pipe 12 and the third pipe 13 are respectively connected to the filter cylinder 15, and the first valve body 1 to the fifth valve body 5 are all electric valves, and in other embodiments, the first valve body 1 to the fifth valve body 5 are all pneumatic valves or other valves controlled automatically, and the opening and closing of the valve bodies are controlled automatically by connecting an external main control system.

Illustratively, as shown in fig. 1, the first valve body 1, the second valve body 2 and the third valve body 3 are all disposed between the filter cylinder 15 and the first driving module 8, the third valve body 3 is used for switching the water flow between the filter cylinder 15 and the first driving module 8 in the third pipe 13, the second valve body 2 is used for switching the water flow between the filter cylinder 15 and the first driving module 8 in the second pipe 12, and the first valve body 1 is used for switching the water flow between the filter cylinder 15 and the first driving module 8 in the first pipe 11. The fourth valve body 4 is arranged between the filter bowl 15 and the area for discharging the water flow after the filter material 17 has been cleaned, the fourth valve body 4 being arranged for switching on and off the water flow in the first conduit 11 between the filter bowl 15 and the area for discharging the water flow after the filter material 17 has been cleaned. The fifth valve body 5 is arranged between the filter cylinder 15 and the first area, and the fifth valve body 5 is used for switching on and off the water flow between the filter cylinder 15 and the first area in the second pipeline 12 so as to realize circulating filtration. For example, if the first area is a swimming pool, the liquid in the swimming pool is filtered by the filter material 17 and then discharged into the swimming pool, so as to realize the circulation filtration. In other embodiments, the filtered liquid is discharged through the fifth valve body 5 to an external storage device for storing the filtered liquid.

The seventh valve body 7 is connected in series with the fourth valve body 4, and the seventh valve body 7 is a manual valve for manually controlling the flow rate of the water flow above the filter material 17 discharged to the outside of the filter cylinder 15.

Specifically, the third pipe 13 is disposed above the filter material 17, and the water outlet direction is deviated from the radial direction of the inner wall of the cylinder, for outputting a cleaning water flow or a water flow to be filtered, so as to form a rotating water flow above the filter material 17, and the impurities deposited on the filter material 17 are rotated by the rotating water flow. A viewing window 16 for observing whether a rotating water flow is formed above the filter material 17 is provided in the side wall of the filter bowl 15. The cleaning water flow may be water flow to be filtered, or may be water flow with less impurities than the water flow to be filtered.

Preferably, a tangential direction of a junction center point of the third pipe 13 and the filter bowl 15 is defined as a first direction, a water outlet of the third pipe 13 is defined as a swirl water outlet 31, and a water outlet direction of the swirl water outlet 31 is defined as a second direction. In the first embodiment, the third conduit 13 remains straight after entering the filter cylinder 15, and the second direction is parallel to the horizontal plane. The first direction is set to an angle ranging from greater than 0 deg. to less than 90 deg. to the second direction to create a steady rotating water flow over the filter material 17.

In other embodiments, the third conduit 13 remains straight after entering the filter bowl 15, and when the angle between the first direction and the second direction is 90 °, the water flow from the third conduit 13 will flow toward the central axis of the filter bowl 15 (as shown by the dashed line in fig. 3), thereby making it impossible to create a steady rotational water flow. When the angle between the first direction and the second direction is 0 °, the water flowing out of the third pipe 13 directly collides against the inner wall of the filter cylinder 15, and thus a stable rotating water flow cannot be formed.

When the second direction is perpendicular to the horizontal plane, the water flow discharged from the third pipe 13 flows vertically toward the filter material 17 or toward the top of the filter cylinder 15, resulting in failure to form a rotating water flow.

During back flushing, a rotating water flow is generated for rotating the impurities, above the clean-up filter material 17 in its entirety, and then discharged through the first pipe 11 and the fourth valve body 4.

Further, the first driving module 8 is a first driving device and a second driving device, and the first driving device is started when the first pipeline 11 outputs water flow to be filtered; the second drive means is activated when the second conduit 12 injects a flow of cleaning water towards the filter material 17. Illustratively, the first drive means and the second drive means are each arranged as drive means for driving the movement of the liquid, such as a water pump or the like. In another embodiment, the first driving module 8 comprises a variable frequency driving device, and the operating state of the variable frequency driving device comprises a first state and a second state, and the power of the variable frequency driving device when operating in the second state is larger than the power of the variable frequency driving device when operating in the first state. The variable frequency driving device works in a first state when the first pipeline 11 outputs water flow to be filtered; the variable frequency drive operates in a second state when the second conduit 12 is injecting a flow of cleaning water towards the filter material 17.

The second driving module 9 is connected to the third pipe 13 and the first area, and is only used for driving the third pipe 13 to output water flow to be filtered or cleaning water flow.
