[0039] Optionally, the filter hole diameter of the vertical filter plate 53 is larger than the filter hole diameter of the first filter screen 7 .

[0040] The working principle of the water circulation decontamination device based on multi-stage decontamination is as follows: the liquid to be filtered enters the decontamination device body 2 through the liquid inlet 21, the liquid to be filtered undergoes the first centrifugal separation through the first spiral partition plate 42 (the spiral partition plate changes the flow direction of the liquid through its internal structure, generating rotation, and gravel, dirt, etc. having a density greater than that of water are centrifuged to the outside), the liquid to be filtered reaches the sedimentation tank 3 through the first spiral partition plate 42, and a plurality of baffles 31 are provided on the inner wall of the sedimentation tank 3 for swirling flow deceleration to allow gravel, dirt, etc. to settle to the bottom storage space.

[0041] The liquid after the first centrifugal separation is centrifuged for the second time through the second spiral partition plate 52 and the third spiral partition plate 54 inside the first support column 41. The second spiral partition plate 52 is used to change the flow direction of the liquid to produce rotation. Since the outer diameter of the third spiral partition plate 54 is smaller than the outer diameter of the second spiral partition plate 52, the sand and dirt separated by centrifugation will be on the outside. When the liquid passes through the third spiral partition plate 54, the sand and dirt on the outside will be intercepted by the collecting inclined plate 46 and discharged directly to the upper side of the drain valve.

[0042] Finally, the liquid is separated by a gas-liquid separator 6 , and the separated gas is discharged to the outside through the first air hole, the second air hole on the outlet pipe 43 , and the exhaust valve; the separated liquid is precisely filtered through the first filter screen 7 .

[0043] In addition, a vertical filter plate 53 is provided on the second spiral component 5. The vertical filter plate 53 plays a filtering role. When the filtered liquid passes through the vertical filter plate 53, it can drive the second spiral component 5 to rotate. On the one hand, it can drive the internal generator to work and power the internal monitoring module; on the other hand, it can provide starting force for the motor to reduce the starting load, and realize high-speed rotation of the second spiral component 5 through the motor, thereby improving the centrifugal separation effect.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention.
