PUMP AND CLARIFIER Filed Nov. 24, 1939 2 Sheets-Shet 1 g fiaeiz/orf I J. F. GREGG I PUMP AND GLARIFIER Jan. 13; 1942.

Filed Nov. 24, 1939 v 2 Sheets-Sheet 2 Patented Jan. 13, 1942 vireo STATES FFICE 1 Claim.

This invention relates to a combination pump and clarifier device for liquids.

The object of the invention is to provide a liquid pump which performs a dual service as a separator or a clarifier.

Another object is to provide means in such a pump and clarifier whereby the objectionable elements separated from the main body of the liquids may be stored within the device.

And a still further object is to provide means available at the will of the operator whereby the objectionable elements stored within the device may be discharged from the body of the liquid and the pump cleaned.

Other objects and benefits will be disclosed in the following descriptions and drawings in which:

Fig. l is an enlarged cross sectional elevation 4 view of the pump clarifier;

Fig. 2 is a plan View of the collector ring;

Fig. 3 is an enlarged cross sectional view of the collector ring through one of the outlet openings as the section would appear on the section lines 4-4 of Fig. 3;

Fig. 4 is an enlarged cross sectional view of the ring through the outlet holes as it would appear on the section lines 5 -5 of Fig. 3;

Fig. 5 is a similar enlarged cross sectional elevation view of the clarifier ring as it would appear on the section lines 6-6 of Fig. 3; and

Fig. 6 is a plan view of the pump cup showing the internal vanes as will later be explained.

Now referring to Fig. 1, the body of my pump clarifier 22 is covered by a cover member 33 having an inlet connection 34 and an outlet connection 35. Integral with this cover member is an internal inverted cup member 36 and a central bearing boss 31. The complete cover 33 is attached to the base member 22 through the flange 38 by bolts 39 as shown.

A cup impeller 40 having a central boss 4| attaches to a drive shaft 42 by means of the tapered end section 43 and the jam nut 44. By this construction it will be appreciated that the impeller cup 40 is firmly attached to the shaft 42 and is revolved by it. The shaft 42 is supported in bearings 45 and 46 separated in the bearing boss 31, whereby to provide an open section between the bearings which I pack with lubricant in order to continuously lubricate the shaft 42. A belt pulley 41 is rigidly attached to the shaft 42 by means of a screw 48 as shown. The entire impeller structure is supported on the cover 33 by an anti-friction washer 49.

The cup impeller 40 is provided with four internal vanes 50, as clearly shown in Fig. 6. Also, the impeller 43 has two central circulation openings 40 to permit recirculation of liquid through the impeller cup to carry out deposits of objectionable elements for storage in the reservoir below.

It will be appreciated that when valve 56 is closed the liquid in the base 22 is under pressure and the impeller 40 is acting as a separator, while when valve 56 is open the impeller acts as a simple centrifugal pump.

The principle of centrifugal separation of the heavier elements from the lighter elements is well known in the art and will not be described in great detail. Sumce it to say that the clarified liquid passes through the restricted openings 54 of the separator ring 5| as a result of the centrif ugal force generated by the cup impeller 40. It will be noted that the openings 54 are slightly removed from the outer wall 36 and surrounded by a projecting lip.

From the foregoing applicant has disclosed a pump which serves the dual service of a separator or clarifier.

Having thus described my invention, I claim:

In a device of the class described, a stationary centrifugal pump housing, a cup-shaped rotary impeller having internal vanes mounted in said housing, a sediment storage space under the impeller in the housing, a liquid inlet to the bottom of said cup-shaped impeller, a liquid discharge outlet spaced inwardly from the lip of the cup impeller leaving an outlet space between the liquid outlet and the lip for the discharge of sediment into the housing, restricted circulation holes in the bottom center section of the cup impeller, said discharge outlets and restricted circulation holes being proportioned and arranged to permit clarified liquid to be discharged to the exterior of the housing and the separated sediment to be retained in the storage space, and valve outlet means from the bottom of the storage space to permit liquids to be discharged therethru whereby the storage space is cleared of sediment and dirty liquid.
