2 Claims' (Cl. 233-24) This invention relates to centrifugal separators, and an object of the invention 'is to provide'a separator which will separate heavy or unclean liquid containing foreign matter fr m lighter or 5 cleaner liquidby centrifugal action.
5 of a partition 1.
A rotor 8 is rotatably mounted in the casing I inany suitable manner such as by means of shaft ends!) and I and suitable bearings H.
The rotor 8 comprises a cylindrical body I 2 3 having a liquid or propelling wheel I4 on one end thereof which is positioned adjacent to the inlet M has vanes l5 therein so that the fluid flowing into the casing I, under pressure, and engaging the wheel M will rotate the rotor 8.
The liquid to be filtered or separated, after passing into the casing l and through the liquid wheel l4, passes longitudinally through the cylindrical body l2 of the rotor where the centrifugal action set up by the wheel I 4 will cause the lighter fluid to flow to the center and the heavy liquid orthe impurities in the liquid to flow towards the periphery of the whirling column. The rotor 8 has a nozzle l 6 centrally located at its end remote from the liquid wheel M, which nozzle serves as an outlet for the lighter or clean liquid. The clean liquid passes'from the nozzle [6 into the substantially cylindrical body l'l'from which it flows through. the outlet opening is into the chamber outlet 4. v
The heavy liquid containing the impurities is picked up by a pump impeller i9 formed on the rotor concentrically of the nozzle I 6. peller l9 forces the impure or heavy liquid outwardly through the chamber I9 and outlet 3.
The cylindrical body 5 2 has a longitudinally ex- 5 and thence out through the distance from the longitudinal axis of the cylindrical body I2. The vane 20 facilitates the separation of the heavy or dirty fluid containing the impurities and the lighter or clean liquid.
It will be understood that the invention is not to be limited to the specific construction or arrangement of parts shown, but that these may be modified widely within the invention as defined by the claims.
What is claimed is:
1. In a centrifugal separator, a stationary casing having a pair of spaced chambers thereon and a cylindrical portion connecting said chambers, said casing having an outlet liquid, and an outlet for impure or heavy liquid, said latter outlet opening into one of said chambers, a rotor in said casing including a hollow cylindrical body mounted within said cylindrical portion and in sealed relation therewith, a propeller wheel at one end of said body and positioned in one of said chambers, an impeller at communicating with said casing outlet for light liquid.
2. In a centrifugal separator, a stationary casing having a pair of spaced chambers thereon and a cylindrical portion connecting said chambers, said casing having anoutlet for clean or light liquid, and an outlet for impure or heavy liquid, said latter outlet opening into one of said cham-. bers, a rotor in said casing including a hollow cylindrical body mounted within said cylindrical portion and in sealed relation therewith, a proother chamber, a substantially cylindrical outlet for, light liquid axially disposed opening into said rotor at one end'and having an outlet communicating with said casing outlet for light liquid, and a radial rib extending longitudinally in said cylindrical body between said propeller and impeller. 4
