ANDREW PETERSON, 01F BROOKLYN, YORK.
PUMP AGITATOR.
a lication filed July 24, 1923. Serial no. 653,526.
To all whom it may concern:
Be it known that I, ANDREW PETERSON, a citizen of the United States of America, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Pump Agitators, of which the following is a specification.
My invention has for its object to furnish an air agitator and mixer at the suction end of a pumping apparatus.
My invention has 'for its object to break up solid and semi-solid material and mix water therewith into an intimate emulsion which can be handled by the pumping apparatus.
My invention has for still further an object to use com ressed air as a pumping agent, the air, being injected into the resulting mixture or emulsion which is to be pumped from the air agitator.
In the drawing: Fig. 1 is a general layout of a dredging barge using my invention.
Figures 2 and 3 show the detail construction of the air agitator with the discharge hose shown removed in Figure 3.
Referring to the drawing in which like reference characters designate corresponding parts, 1 designates the dredging barge proper on which the air compressor (2) is mounted. The air agitator (3) is suspended from the boom (4) by means of a wire rope 5), which winds up over the hand-driven drum (6). The flexible hose (7) is coupled to the discharge pipe (8) of the air compressor (2) and is screwed into the connection (9) situated at the top of the air agitator (3). A small hole (10) is drilled in the connection (9). A nozzle (11) at the end of a bent pipe is centrally placed in the discharge opening (12) of the air agitator (3), the discharge opening (12) being located Well down from the top of the air agitatoi' (3) thus leaving a chamber (13) adapt.- ed for the trapping of air which enters through the opening (10) into the chamber 13). Peripheral openings (14) located at the bottom rim of the air agitator (3) admit water to the air agitator (3) and this water,
together with the dredged material is dischar ed into the dredging barge (1) through the exible hose (15).
The operation is as follows:
The air agitator (3) is lowered to the bottom until a slack in the line (5) appears.
The compressor (2) having been started, the compressed air enters the'discharge hose (15) through the nozzle (11).
Compressed air enters the air agitator (3) through the opening (10) and is trapped in the top part (13) of the air agitator (3).
The air in entering the discharge hose (15) mixes with the water and propels the water through the discharge hose (15) into the dredging barge (1).
In the meantime air enters the air agitator (3) through the small opening (10) and is trapped in the upper part (13) of the air agitator (3).
The air being an elastic medium will immediately respond to a momentarily pressure difference and a pulsating movement will occur, which churns up the dredged material in the water entering into the lower part of the agitator (3) through the openings (14-).
Also when the air entering the trap top reaches the discharge opening (12) the contained air will suddenly blow into the discharge hose (15). The compensating water cannot enter quickly enough through the openings (14) and the bottom to be dredged will bulge into the air agitator which will consequently he pulled down as far as the slack in the line (5) allows;
For certain material it will be found advantageous to use a screened bottom for the air agitator and the bottom will, in bulging into the air agitator, be cut up into fragments by the screen.
The barge is moved along as the dredging proceeds and the operation is repeated.
I claim:
The method of trapping air into the top of an inverted and submerged air chamber open at the bottom and resting upon the material to be pumped. the subsequent and repeated discharge of said trapped air causing pulsating action of the water contained in the lower part of the submerged air chamber. said action breaking up and mixing the material to be pumped with the water entering the submerged air chamber.
ANDREW PETERSON.
