Background
Centrifuges are machines that utilize centrifugal force to separate components of a mixture of liquid and solid particles or liquid and liquid. The centrifuge is mainly used for separating solid particles from liquid in suspension, or separating two liquids which have different densities and are insoluble with each other in emulsion (for example, cream is separated from milk); it can also be used to remove liquids from wet solids, such as by spin drying clothes in a washing machine; the special overspeed tubular separator can also separate gas mixtures with different densities; some sedimentation centrifuges can also grade solid particles according to density or granularity by utilizing the characteristic that the solid particles with different densities or granularities have different sedimentation speeds in liquid; the action principle of the centrifugal separator includes centrifugal filtration and centrifugal sedimentation. Centrifugal filtration is to make the suspension generate centrifugal pressure under the centrifugal field to act on the filter medium, so that the liquid passes through the filter medium to become filtrate, and solid particles are trapped on the surface of the filter medium, thereby realizing liquid-solid separation; centrifugal sedimentation is the principle that components with different densities of suspension (or emulsion) are quickly settled and layered in a centrifugal force field to realize liquid-solid (or liquid-liquid) separation. The existing spiral sedimentation centrifuge is suitable for separating suspension with low solid content due to sedimentation separation, and can obtain a clear liquid phase, but the water content of discharged solid phase is generally higher, so that improvement is needed.

Detailed Description
In order to make the technical solution of the present invention better understood, the present invention is described in detail below with reference to the accompanying drawings, and the description of the present invention is only exemplary and explanatory, and should not be construed as limiting the scope of the present invention.
As shown in fig. 1-2, the specific structure of the present invention is: the device comprises a rear rotary drum 1, wherein the rear rotary drum 1 comprises a settling rotary drum section 101 and a filtering straight rotary drum section 102; the settling drum section 101 is a non-porous drum; a front rotary drum 7 is movably arranged at the side end of the filtering straight rotary drum section 102, the front rotary drum 7 is set as a filtering conical rotary drum section, and a column section screen 6 and a conical section screen 8 are respectively arranged on the filtering straight rotary drum section 102 and the front rotary drum 7; a spiral conveyor 2 is arranged in the rear rotary drum 1, and the middle part of the spiral conveyor 2 is movably connected with a material pushing shaft 11; a plurality of material distribution holes 12 are formed in the screw conveyor 2, and material blocking rings 5 are arranged inside the screw conveyor 2 and at the side ends of the material distribution holes 12; the side end of the front rotary drum 7 is provided with a scraper 9 and a water retaining ring 10.
Further, the filtering straight drum segment 102 is connected with the front drum 7 through bolts.
Furthermore, the middle part of the screw conveyor 2 is movably connected with the material pushing shaft 11 through a sealing cover 3 and a sealing bolt 4.
Further, the scraper 9 and the water retaining ring 10 are connected through a bolt, and the scraper 9 and the front rotary drum 7 are connected through a bolt.
Further, the material blocking ring 5 is connected with the screw conveyor 2 through a bolt.
During the specific use, suspension enters into the material distribution chamber in the auger delivery 2 through the inlet pipe and evenly distributes to subside in the commentaries on classics drum section 101 after accelerating, and under centrifugal force, the solid phase particle of heavier among the suspension subsides fast and forms annular sediment on subsiding the drum section 101 wall, and the upper surface annular liquid layer is subsided to lighter liquid phase then in the annular, constantly adds suspension through the inlet pipe, makes lighter liquid phase discharge from the overflow mouth at the bottom of the rotary drum. Because the spiral conveyor 2 and the rear rotary drum 1 have different rotating speeds, the sediments are conveyed to the filtering straight rotary drum section 102 by the spiral conveyor 2 for further dehydration and then are pushed to the filtering cone rotary drum section for drying, and finally are discharged from the filtering cone rotary drum section and collected by the material collecting groove to be discharged out of the machine. The liquid phase discharged from the settling rotary drum section 101 and the filtering straight rotary drum section 102 is collected by the machine shell and discharged out of the machine shell.
