[0022] Furthermore, a first drive motor 3 and a mud pump 4 are installed on the upper part of the first centrifugal chamber 2, wherein the first drive motor 3 is connected to the separation cylinder 9, and a screening frame 10 is arranged outside the separation cylinder 9, and the bottom limit of the screening frame 10 is installed inside the branch pipe 15, and the middle part of the branch pipe 15 is connected to the return pipe 14;

An inclined guide net 161 is provided in the middle of the separation drum 16, and a slurry outlet pipe 51 is provided on the other side of the separation drum 16.

[0024] Furthermore, one side of the mud pump 4 extends into the interior of the first centrifugal chamber 2 and is provided with a delivery pipe 41, and a first drive motor 3 is provided on the upper part of the first centrifugal chamber 2, and the output end of the first drive motor 3 extends into the top wall of the first centrifugal chamber 2 and is connected to the driving shaft 31, and a separation cylinder 9 is fixedly installed at the bottom of the driving shaft 31, and the body of the separation cylinder 9 is provided with a large-aperture filter.

[0025] Furthermore, a platform frame 11 is installed inside the first centrifugal chamber 2, and an exciter 12 is fixedly installed on the platform frame 11. The exciter 12 is connected to a screening frame 10. The screening frame 10 is installed on the outside of the separation cylinder 9 and does not contact the separation cylinder 9, wherein the inner wall of the screening frame 10 is provided with multiple layers of separation nets 101.

[0026] Furthermore, an inverted Y-shaped branch pipe 15 is provided at the inner bottom end of the first centrifugal chamber 2, and the upper part of the branch pipe 15 is set as an open pipe. A screening frame 10 is installed in the opening in a limited telescopic manner, and another branch pipe of the branch pipe 15 is connected to the delivery pump 5.

[0027] Furthermore, an isolation net 13 is provided in the branch pipe of the branch pipe 15 on the side facing the delivery pump 5 , and the two branch pipes located in the branch pipe 15 are connected through a reflux pipe 14 .

[0028] Furthermore, the output end of the second drive motor 7 extends into the interior of the second centrifugal chamber 6 and is drivingly connected to the separation drum 16. Inclined guide nets 161 are provided on both sides of the inner wall of the separation drum 16, and the other side of the separation drum 16 is rotatably installed on the inner wall of the second centrifugal chamber 6, and a slurry outlet pipe 51 is provided in the middle of this side, and the slurry outlet pipe 51 is connected to the conveying pump 5.

The first drive motor 3 drives the separation drum 9 to rotate centrifugally at high speed, and performs preliminary separation of the solid and liquid in the mud and rock slurry. At this time, under the screening effect of the separation drum 9, the large particles of solid phase will be preferentially separated to the external screening frame 10, while the small particles of solid phase may still be attached to the liquid phase. At this time, the exciter 12 is driven, and the exciter 12 generates an exciting force and transmits it to the screening frame 10. The multi-layer separation net 101 in the screening frame 10 separates the large particles of solid phase. High-frequency vibration screening is carried out to further remove the mud on its surface, and then the material will fall to the bottom of the screening frame 10 under the action of continuous vibration.

The second centrifugal chamber 6 is driven by the second drive motor 7 to perform high-speed centrifugal rotation, and cooperates with the inclined guide net 161 provided therein to further separate the mud and stone slurry, and leave the solid phase in the separation drum 16, and the liquid phase is conveyed to the mud and water tank 8 at the bottom of the frame 1 through the connecting pipe.

[0030] Among them, in actual use, the first centrifugal chamber 2 grades and screens the solid phase, so that the solid phase ratio is effectively controlled and graded, and further controlled centrifugation is performed through the second centrifugal chamber 6. Compared with the traditional centrifugal equipment with a single centrifugal structure, this device can effectively control the solid phase ratio, improve the quality and efficiency of solid phase separation, and ensure the quality of soil remediation.

[0031] In the utility model, through multiple separation operations of the first centrifugal chamber 2 and the second centrifugal chamber 6, effective separation of the solid and liquid phases in the mud and rock slurry water is achieved. Compared with the traditional separation equipment, the large particle solid phase in the mud and rock slurry is initially separated by the separation cylinder 9 and the screening frame 10 arranged in the first centrifugal chamber 2, and the liquid phase is introduced into the second centrifugal chamber 6 through the branch pipe 15 for further controlled separation. This process can effectively control the solid phase in the mud and rock slurry by graded control, improve the separation efficiency, and ensure the resource utilization of the solid phase.
