Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the following will explain in detail a preferred embodiment of the present invention with reference to the accompanying drawings to facilitate understanding of the skilled person.

The utility model discloses a centrifugal inner roller type solid-liquid separator, which comprises a shell 1, a screen 2, a spiral feeding device 3, a filtrate box 4, a motor 5 and a speed changer 6, and is shown in figures 1-2; a discharge port 11 is arranged at the front end of the shell 1, a bearing I12 is arranged in the center of the discharge port 11, a feed pipe 13 is connected to the rear end of the shell 1, a feed port 131 is arranged on the feed pipe 13, and a bearing II 14, a transmission 6 and a motor 5 are sequentially arranged at the tail end of the feed pipe 13; the screen 2 is in a circular tube shape and is transversely installed in the shell 1, the spiral feeding device 3 is installed in the screen 2 and comprises a rotating shaft 31 and a spiral blade 32, the diameter of the rotating shaft 31 is thick in the front and thin in the back, the front end of the rotating shaft 31 is connected with the first bearing 12, the rear end of the rotating shaft 31 penetrates through the second bearing 14 to be connected with the transmission 6, the spiral blade 32 is arranged on the outer side of the rotating shaft 31, and the filtrate tank 4 is arranged at the lower end of the screen 2 and connected with the shell 1.

When the device is specifically applied, solid-liquid materials of the septic tank are sucked into a feed port 131 of the centrifugal inner roller type solid-liquid separator through the vacuum pump, then the motor 5 and the speed changer 6 are started, the motor 5 drives a rotating shaft 31 connected with the speed changer 6 to rotate, so that the spiral feeding device 3 conveys the solid-liquid materials of the septic tank from a feed pipe 13 to a discharge port 11, as the rotating shaft 31 of the spiral feeding device 3 is thick in the front and thin in the back, the diameter of the rotating shaft is thicker when the rotating shaft is closer to the discharge port 11, and the rotating radius of the spiral blades 32 is the same, the extrusion force between the solid-liquid materials in the septic tank and the filter screen 2 can be continuously enhanced in the process of continuously moving towards the discharge port 11, so that filtrate is filtered more fully, and the filtrate which does not pass through the filter screen can continuously flow back along the inclination of the rotating shaft 31 when the rotating shaft 31 is thick in the front and thin, so that the filtrate amount brought by filter residues is reduced; solid-liquid material in the septic tank constantly extrudees the filtration in 3 data send processes of spiral feeding device, and filtrating passes through the filter screen and gets into filtrate case 4, and the filter residue is discharged from discharge gate 11, can make the solid-liquid separation of septic tank more thorough through using this device, and the simple efficient of separation step can reduce the maintenance cost of filter screen simultaneously.
