[0040] The difference between the embodiment five and the embodiment one is that the outer side of the transmission shaft 26 is provided with a fixing frame connected to the top end of the machine base 1.

[0041] The transmission of the transmission shaft 26 is more stable.

[0042] The difference between the embodiment six and the embodiment one is that the top end of the top liquid inlet pipe 28 is provided with a communication pipe provided with a connecting flange.

[0043] The connection of the top liquid inlet pipe 28 is more convenient for the user.

[0044] The sedimentation centrifugal combined cylinder 3 comprises an outer convex sedimentation centrifugal combined cylinder 31 and an inner concave centrifugal combined cylinder, the inner wall of the inner concave centrifugal combined cylinder is uniformly provided with a plurality of liquid discharge holes 8, the sidewall of the middle part of the material discharging cavity 5 is provided with a material outlet 9, the outer side of the material outlet 9 is provided with a material discharging channel 10, the bottom end of the machine shell 2 is symmetrically provided with two bottom liquid outlets 30, and the two liquid outlets 30 are symmetrically distributed about the material discharging channel 10.

[0046] The equipment feeding port continuously feeds the material into the high-speed rotating rotating drum to obtain centrifugal force. Since the solid and liquid phases of the material have different densities, the obtained centrifugal force is also different. The solid phase with large density is close to the rotating drum and is pushed to the middle of the rotating drum by the spiral blades on both sides and is discharged from the material outlet in the middle of the rotating drum into the discharge hopper. The liquid phase is suspended above the solid phase and slowly accumulates, and when it exceeds the overflow port on the bottom of the rotating drum on both sides.

[0047] The solid material enters the outer rotating drum through the feeding port 7, settles and stratifies first;

[0048] Most of the liquid phase flows out from the overflow port; the solid phase material containing moisture is pushed to the material outlet by the bidirectional pushing spiral blade and is discharged, during which the material passes through the filter screen and the moisture in the solid phase material is discharged through the drainage port 12. The liquid discharge hole 8 is a material washing hole

[0049] In the prior art, the rotor of the spiral discharge sedimentation filtration centrifuge is mostly provided separately, and the sedimentation filtration efficiency of the material in the centrifuge is low, and the discharge of the material after sedimentation filtration and waste liquid is troublesome, which cannot meet the rapid feeding sedimentation filtration use of the user.

[0050] In summary, when the user needs to perform sedimentation filtration on the material, the user first feeds the material into the sedimentation centrifugal combined cylinder 3 through the feeding pipe 20. The side of the feeding pipe 20 is provided with a discharge port 22, so that the material can be uniformly fed into the sedimentation centrifugal combined cylinder 3 through the end of the feeding pipe 20 and the discharge port 22.

[0051] Then, the user drives the main transmission sleeve rod 17 to rotate by the motor, so that the main transmission sleeve rod 17 can drive the sedimentation centrifugal combined cylinder 3 to rotate through the rotating support frame 15. The other end of the sedimentation centrifugal combined cylinder 3 is driven by the motor to drive the auxiliary transmission sleeve rod 27, so that the auxiliary transmission sleeve rod 27 drives the transmission shaft 26 to rotate. After the speed is adjusted by the differential mechanism 25, the adjusted speed drives the sedimentation centrifugal combined cylinder 3 to rotate through the middle transmission rod 24, so that the two ends of the sedimentation centrifugal combined cylinder 3 can be accelerated and driven. Thus, the fixed particles and the liquid in the material are separated and layered under the action of the centrifugal force. The fixed particles are deposited on the inner wall of the sedimentation filtration rotating drum 11, and the liquid forms a liquid ring to fill the rotating drum.

[0052] The liquid adhering to the inner wall of the sedimentation centrifugal combined cylinder 3 can overflow into the discharge cavity 5 through the liquid discharge hole 8. The sidewall of the discharge cavity 5 is provided with a water outlet 12, and the side of the water outlet 12 is provided with a filter screen 13. The filter screen 13 can filter the liquid, and the filtered liquid is discharged into the bottom side of the casing 2 through the water outlet 12, and finally discharged through the bottom liquid outlet 30. The fixed particles in the filtration are pushed into the discharge cavity 5 through the feeding port 7, and then concentrated and moved to the discharge port 9 through the bidirectional pushing screw 6 arranged in the discharge cavity 5.

[0053] The material after sedimentation filtration is discharged through the discharge channel 10, so as to complete the sedimentation filtration treatment of the material. The device can more quickly and conveniently perform sedimentation filtration on the material, and the efficiency is twice that of the ordinary centrifuge. Moreover, the discharge of the material and the waste liquid is more convenient, which can meet the sedimentation filtration use of the user.
