[0024] The midpoints of the centrifugal device 2, the feeding device 3 and the differential 4 are located on the same horizontal line, and the feeding pipe 31 is connected to the center of the side of the feeding device 3 away from the centrifugal device 2, the centrifugal device 2 is provided with a rotating drum 21 and a spiral distributor 22, and the spiral distributor 22 is arranged at the inner center of the rotating drum 21, the feeding device 3 is provided with a delivery pipe 33 and a connecting bin 34, and one end of the delivery pipe 33 is connected to the feeding pipe 31, the connecting bin 34 is connected to the end of the delivery pipe 33 away from the feeding pipe 31, and the side of the connecting bin 34 away from the delivery pipe 33 is connected to the spiral distributor 22, and the spiral distributor 2 2 is provided with a group of discharge holes 221, and the outer side of the spiral distributor 22 is evenly provided with spiral plates 222, a differential output shaft 42 is provided on one side of the differential 4, and the differential output shaft 42 is connected to the centrifugal device 2, a motor output shaft 51 is provided on one side of the centrifugal motor 5, and the differential output shaft 42 is connected to the motor output shaft 51 through a transmission belt 52, a water outlet device 23 is connected to the side of the drum 21 close to the feeding device 3, and a plurality of groups of water outlets 231 are provided on the water outlet device 23, and the water outlet device 23 is arranged above the water outlet 6, and a sewage outlet device 24 is connected to the side of the drum 21 close to the differential 4, The sewage discharge device 24 is provided with a plurality of sewage outlets 241, and the sewage discharge device 24 is arranged above the sewage outlet 7. The centrifugal motor 5 drives the differential output shaft 42 to rotate, and then the differential output shaft 42 drives the motor output shaft 51 to rotate through the transmission belt 52, so that the centrifugal device 2 connected to the motor output shaft 51 rotates. The differential 4 is used to control the differential speed of the drum 21 and the spiral distributor 22. The drum 21 and the spiral distributor 22 rotate at a certain differential speed in the same direction. The material enters the spiral distributor 22 from the feed pipe 31 through the conveying pipe 33 via the connecting bin 34, and then in the spiral distributor 2 2 and enter the drum 21 through the discharge hole 221. Under the action of the centrifugal field, the heavier solid phase is deposited on the wall of the drum 21 to form a sediment layer. The spiral plate 222 continuously pushes the deposited solid phase to the sewage discharge device 24, and then it is discharged from the sewage outlet 241 on the sewage discharge device 24. The solid impurities are discharged out of the machine through the sewage outlet 241. At the same time, the lighter liquid phase forms an inner liquid ring, and continuously overflows the drum 21 from the water outlet 6 at the water outlet device 23 of the drum 21, and is discharged out of the machine through the water outlet 6. The differential 4 is an involute planetary gear differential, which has the advantages of large transmission ratio and high precision.

[0025] A connection port 63 is provided at the bottom of the water outlet 6, and a connection pipe 61 is provided on one side of the water outlet 6. A purification device 62 is connected in the connection pipe 61. The purification device 62 includes a connection knob 621 and a fixed clamp block 623. A connection bolt 622 is connected between the connection knob 621 and the fixed clamp block 623. The purification device 62 is threadedly connected and fixed to the connection pipe 61 through the connection bolt 622. The fixed clamp block 623 is provided with multiple groups, and the outer sides of the multiple groups of fixed clamp blocks 623 are connected with elastic rings 624. The fixed clamp block 623 is internally connected with an activated carbon filter element 6. When the separated liquid passes through the water outlet 6, it is purified again by the purification device 62 in the water outlet 6. The activated carbon filter element 6 inside the purification device 62 absorbs the difficult-to-degrade organic matter, nitrogen and phosphorus and other soluble inorganic matter in the water that can cause eutrophication of the water body. The purification device 62 can be replaced by taking it out from the connecting pipe 61. By turning the connecting knob 621, the connecting bolt 622 is unscrewed from the connecting pipe 61, and at the same time, the fixed clamp block 623 and the activated carbon filter element 6 fixedly connected thereto are driven to move, and then the fixed clamp block 623 is pulled out. During the pulling out process, the fixed clamp block 623 contracts inwardly and drives the elastic ring 624 to contract together. After the purification device 62 is completely pulled out, the activated carbon filter element 6 is pulled out from the fixed clamp block 623 and replaced.

[0026] Working principle: When using a centrifuge for automatic solid-liquid separation, first, plug the purification device 62 into the water outlet 6 through the connecting pipe 61, and thread the connecting bolt 622 to the connecting pipe 61 by turning the connecting knob 621. During the connection process, the fixed clamp block 623 contracts inwardly and drives the elastic collar 624 to contract together, and enters the inside of the water outlet 6 through the connecting pipe 61. After completely entering the inside of the water outlet 6, the fixed clamp block 623 expands outwardly and drives the elastic collar 624 to expand together. After the installation is completed, start the machine, and discharge the sewage to be treated into the centrifugal device 2 through the feeding device 3. The liquid part of the sewage treated by the centrifugal device 2 is discharged through the water outlet device 23, and the fixed impurities are discharged through the sewage outlet device 24. Finally, they are discharged from the machine body through the water outlet 6 and the sewage outlet 7 respectively.

[0027] The centrifugal motor 5 drives the differential output shaft 42 to rotate, and then the differential output shaft 42 drives the motor output shaft 51 to rotate through the transmission belt 52, so that the centrifugal device 2 connected to the motor output shaft 51 rotates. The differential 4 is used to control the differential speed of the drum 21 and the spiral distributor 22. The drum 21 and the spiral distributor 22 rotate at a certain differential speed in the same direction. The material enters the spiral distributor 22 from the feed pipe 31 through the conveying pipe 33 and the connecting chamber 34, and then accelerates in the spiral distributor 22. Then, the solid impurities are discharged out of the machine through the sewage outlet 241. Meanwhile, the lighter liquid impurities form an inner liquid ring, which continuously overflows from the drum 21 through the water outlet 6 at the water outlet 23 of the drum 21 and is discharged out of the machine through the water outlet 6.

[0028] When the separated liquid passes through the water outlet 6, it is purified again by the purification device 62 in the water outlet 6, flows through the activated carbon filter element 6 through the gap between the fixed clamps 623 inside the water outlet 6, and adsorbs the difficult-to-degrade organic matter, nitrogen and phosphorus and other soluble inorganic substances that can cause eutrophication of the water body in the water through the activated carbon filter element 6. After the sewage treatment is completed, the activated carbon filter element 6 can be replaced by removing the purification device 62 from the connecting pipe 61.
