Centrifugal separator

Claim 2

A centrifugal separator comprising 1. a housing, the housing including a. an upper portion, b. a fixedly supported lower portion, and c. an elastic support means resiliently supporting the upper housing portion of the separator on the lower separator housing portion; 2. a vertically extending pivot in said housing, d. the pivot being carried by the upper separator housing portion; and 3. a separating bowl having a hub mounted for rotation on and about said pivot and carried thereby; e. the pivot extending into the interior of the bowl, f. the upper separator housing portion and all elements carried thereby, including the pivot and the bowl, having a center of gravity, and g. the elastic support means being positioned approximately at the level of the center of gravity.

Claim 3

a vertically extending pivot in said housing, d. the pivot being carried by the upper separator housing portion; and

Claim 4

a vertically extending pivot in said housing, d. the pivot being carried by the upper separator housing portion; and

Claim 5

The centrifugal separator of claim 1, further including a screen mounted over the interior surface of the bowl and spaced therefrom.

Claim 6

The centrifugal separator of claim 2, wherein the bowl and the screen are frusto-conical, and the elastic support means is positioned approximately at the level of the geometric center of gravity of the interior surface of the frusto-conical bowl.

Claim 7

a separating bowl having a hub mounted for rotation on and about said pivot and carried thereby; e. the pivot extending into the interior of the bowl, f. the upper separator housing portion and all elements carried thereby, including the pivot and the bowl, having a center of gravity, and g. the elastic support means being positioned approximately at the level of the center of gravity.

Claim 8

a separating bowl having a hub mounted for rotation on and about said pivot and carried thereby; e. the pivot extending into the interior of the bowl, f. the upper separator housing portion and all elements carried thereby, including the pivot and the bowl, having a center of gravity, and g. the elastic support means being positioned approximately at the level of the center of gravity.

Claim 9

The centrifugal separator of claim 1, further comprising a cover on the housing and a feed assembly for delivering material to be separated to the bowl, the feed assembly including a feed pipe having an outlet end, the feed pipe being supported on the housing cover, a conical element fixed to the top of the bowl hub, the outlet end of the feed pipe being in registry with the conical element to deliver the material to said element, a turbine wheel having radially extending blades fixed to the conical element, the blades defining spaces therebetween concentrically surrounding the conical element and receiving the material from the conical element, an outwardly flaring tube fixed to the turbine wheel and surrounding the hub, an annular chamber being defined between the tube and the hub for receiving the material from said spaces, the lower end of the tube defining with the bottom of the bowl a circular delivery opening means for delivering the material to the bowl, and the upper end of the tube surrounding the outlet end of the feed pipe.

Claim 10

The centrifugal separator of claim 4, further comprising a joint between the upper end of the tube and the outlet end of the feed pipe.

Claim 11

The centrifugal separator of claim 1, wherein the upper housing portion comprises an upper and a lower wall portion, the thickness of the upper wall portion exceeding that of the lower wall portion.

Claim 12

The centrifugal separator of claim 1, wherein the elastic support means comprises blocks of elastic material.

Claim 13

The centrifugal separator of claim 1, wherein the elastic support means comprises a ring of elastic material mounted between the upper and lower separator housing portions.

Claim 14

The centrifugal separator of claim 1, further comprising a tight joint between the upper and lower separator housing portions.
