Referring to fig. 1, a dual-central-cylinder internal-rotation type cyclone pool comprises a pool body, a central cylinder 1, a water inlet tank 3 and a central cylinder support frame 7, wherein a sediment zone 6 is arranged at the bottom of the pool body, and the central cylinder 1 comprises an inner central cylinder 101 and an outer central cylinder 102; a swirl zone 2 is arranged between the inner central cylinder 101 and the outer central cylinder 102; the bottom of the cyclone area 2 is communicated with the sediment area 6; the water inlet tank 3 is connected with the cyclone area 2 along the tangential direction of the inner wall of the outer central cylinder 102, the water pump 9 is arranged above the sediment area 6, and the sediment grab bucket 8 connected with the steel wire rope enters the sediment area 6 from the middle area of the inner central cylinder 101.
In this embodiment, the apron plate 4 is installed at the bottom of the inner central cylinder 101, and the apron plate 4 and the inner central cylinder 101 are inclined towards the outer central cylinder 102 at a certain angle; the cyclone area 2 is provided with a flow channel 5, the upper end of the flow channel 5 is connected with the water inlet tank 3, and the lower end is connected with the sediment area 6.
The flow passage 5 can be downward spirally stepped or downward smoothly and integrally, and in this embodiment, the flow passage 5 is downward spirally stepped.
