Abstract
Abstract of the Disclosure A manure agitation system directed to an open top tank for storage of manure slurry. A gate valve is located in the floor of the tank which can be opened from outside the tank to draw manure slurry from the inside of the tank through a piping system and pump assembly and flow it under pressure through the piping system to an agitator nozzle for substantially high pressure discharge and located inside the tank generally centrally of the floor of the tank and which can be rotated to different positions from outside the tank. A pair of first and second flow control valves are opened to permit the flow of the manure slurry as described and a third control valve is then in closed position. When the third flow control valve is opened and the flow control valve controlling flow to the agitator nozzle is closed then the manure slurry is diverted through the piping system for discharge to a manure spreader or into the top of the stored manure slurry to agitate the same, and break the crust thereon, the discharge to the spreader or tank depending on the open or closed position of a fourth control valve located in the piping system.
Description
L8~
Background of the Invention Previous systems for the agitat:Lon of manure stored in an open top tank utilized a single center agitation nozzle as in Kellogg U.S. Patent 3,367,583 which was operated from the top and spaced from the floor of the t:ank~ The nature of manure storage depends on successful mixing ana blending of solids and fibers with the liquid in the manure into a homo-genized mass which can easily be handled with pumps and field spreading equipment. Also a system to break the crust in the upper portions of the stored manure slurry is required. The present invention provides an emergency system whereby manure may be withdrawn from the storage tank and circulated into the top of the crust to break it up or the manure may be ' discharged into a spreader.
Summary of the Invention The invention is directed to a system for agitating animal manure stored in a tank to mix and blend solids, fibers and liquid into a homogenous mass for easy handling by p~nps and field spreading equipment. The system employs a generally centrally located rotatable nozzle supported in the floor of the tank. A gate valve located inside the tank is connected ` by a piping system through a pump to the centrally located nozzle. The piping system has three flow control valves so when the gate valve is open and two of the flow control valves are open manure will be withdrawn from the tank through the ga~e valve and flowed by a pump through the piping system for discharge through the nozzle. The third flow control valve is closed at this time. When the third flow contr~l valve is open along with the gate valve and the control valve controlling the f~ow of the manure slurry to the nozzle is closed then the ,', . ;
. ~ . , . . .. . . ~ ,~
manure is discharged through a second piping system A fourth flow control valve in a selec-ted open position then discharges the manure to a spreader and in a second selec-ted closed position permits flow of the manure slurry through the second piping system into the upper poxtion of the storag~ ~ank through a rotatable nozzle.

Detailed Description of the Invention Referring to the drawings there is shown a circular preferably open top tank 1 generally of metal which is coated on the inside and outside with a corrosion prevention coatingt not shown, and is supported on the ground by the concrete foundation 2.
Foundation 2 supports a piping system whjch consists of a pipe 3 buried in foundation 2 and connected on the inside to the rotatable agitator nozzle 4 which is located in the .j .~ :
839 `:
floor of tank 1 generally central of the circular wall of tank 1. Pipe 3 then ex-tends outwardly through the foundation : 2. The p.iping system then consists of a pipe S which connects to pipe 3 and ex-tends circumferen-tially along foundation 2 to the discharge end of the centrifugal pump 6. The plping system then in turn consis-ts of a pipe 7 which is connected to the intake side of pump 6 and extends through foundation 2 to a gate valve 8 which is located in the floor of tank 1 and disposed to receive the stored manure slurry when open. ~ .
, A first flow control valve is located in pipe 7 :
immediately ahead of the intake side of pump 6. A seond flow control valve 10 is located on the discharge side of pump 6 between pipes 3 and 5.
The piping system is completed by stub pipe 11 which i.s connected to the circumferentially extending pipe 5 between pump 6 and the second flow control valve 10 and to the third : ~
' control valve 12. Pipe 13 which is of tow parts extends~ :.
vertically upwardly of the wall of tank 1 and to the top of the tank where it is connected to a nozzle 14 which overlies ~: 20 the upper end of the wall of tank 1. Pipe 13 is secured to : the top of tank 1 by a bracket 15 and is rotatable in bracket 15 and in a quick disconnect coupling tube 16, which connects .~ the upper and lower sections of pipe 13, by lever 17 so tha~
: nozzle 14 may be rotated horizontally for discharge of manure 25 slurry into the crust formed on the top of the stored slurry ~ :.
- over a wide range. .
A stub pipe 18 extends from pipe 13 to form a Y~
: shaped construction and is connected to the four-thl flow control. , ; valve 19. When valve 19 is open manure slurry flowing in pipe 13 then flows through stub pipe 18 and flow control valve 19, ~, 83~ :~
to the spreader fill pipe 20 connected to valve 19 for discharge to a manure spreader, no-t shown, and the spreader fill pipe 20 is free to be swiveled in an arc.
The four flow control valves 9, 10, 12 and 19 have ~
similar construction whether operated in cl vertical or horizontal position and the description of one of the valves is sufficient to understand the construction of all of them.
Flow control valve 9 is exemplary o the construction and as shown in Figs. 4 and 5 valve 9 is in closed position. In general flow control valve 9 has a housing 21 which is bolted to the flange 22 on the end of pipe 7 and has a short or tubular extension 23 on the opposite side which fits within the ;
tubular end 24 of the pump 6 and is secured thereto. A rod 25 which extends within housing 21 and projects upwardly and out-wardly therefrom is connected at the inner end to the valve plate 26 and at the outer end is pivoted to the manually actuating lever 27. Lever 27 is in turn pivoted to a fulcrum member 28 which is secured to the top of housing 21i : :j In Figs. 4 and 5 the valve plate 26 is in the closed position whereby flow of manure slurry through pipe 7 to pump 6 -~ is prevented. When lever 27 is pulled outwardly this slides valve plate 26 to an upward position and opens valve ~ and the pipiny system for flow of manure.
Although the fourth flow control valve 19 could be 25 manually actuated as described with respect to the first flow control valve 9 and the internal construction is the same, because flow control valve 19 is a smaller valve i~ is provided with a simple push pull lever 29.
The gate valve 8 which is connected to the inner 30 end of pipe 7 is located in a depression in the concrete floor ~;
,. . '.
of foundation 2 so tha-t manure will readily flow to it. The gate valve 8 has a housing 30 which is secured to foundation 2 by the anchor rods 31 and -the opening 32 in the housing 30 is opened or closed by valve plate or cover 33 to control the flow of manure slurry through valve 8.
The top of valve plate 33 is provided with an abutment assembly 34 to which is secured the inner end of the actuating rod 35 which ex-tends through housing 30 and the floor of foundation 2 and outwardly within casing 36 through the outer upwardly extending portion of foundation 2.
The outer end of rod 35 is pivoted to a generally upstanding lever 37 which is joined by linkage 38 at the bottom to a flat horizontally extending member 39 provided with intermittently spaced notches 40 on the bottomO As upstanding lever 38 is connected to rod 39 by linkage 38 through notches 40 then rod 35 may be pulled or pushed and thereby move the valve :: :
~' plate 33 of gate valve 8 to an open or closed position.
The pump 6 has a driven shaft 41 which is connected - to the drive shaft of a tractor, not shown, so that pump 6 may be actuated from the txactor.
The manure slurry to be stored is loaded into tank 1 either over the top or through the bottom by means of piping, not shown, which could, ~or example, extend from the barn where -~
animals are housed.
In the operation of the agitator assemhly the manure is normally directed upon loading toward the emergency or gate valve 8 with the valve being open.
Thus at start up gate valve 8 is normally open and .~ ~
the third control valve 12 connected to pipes ll and 13 is 3a closed. Flow control valves 9 and 10 are open. Pump 6 is started and -the manure slurry stored in tank 1 then Elows under 3~
static head pressure -through pipe 7, flow control valve 9 and to pump 6. Pump 6 impar-ts velocity and pressure to the manure slurry as the slurry is pushed by the high speed rotating vanes, not shot~, of pump 6 through pipe 5, second control valve 10 and pipe 3 to the agitator nozzle 4. The agitator nozzle 3 discharges khe manure slurry in a high velocity high volume jet into the stored manure slurry for a thorough mixing.
Nozzle 4 may be aimed in any desirable position as it can be rotated 360 from outside tank 1 by a crank 42 which through ~;
a rotatable rod 43 is connected to a gear 44 at the innar end within gear box 45 as illustrated in Fig. 6 t which engages the teeth 46 of the driven gear 47 to rotate the latter. Gear box 45 is closed at the top by the cover 48 which is bolted to the annular wall of gear box 45 and the rod 43 extends through a sealed housing 49 located in foundation 2 and is readily ~ rotated within the square shaped bushing 50 by the crank 42.
;' Nozzle 4 has a flange 51 at the lower end in~turn ;
bolted to the flange 52 of driven gear 47. When gear 47 is rotated this effects rotation of nozzle 4. Nozzle 4 is con-centrically reduced in diameter in its upward extend and ;~ terminates in a somewhat inwardly tapered configuration and at a slight upward slant.
When it is desired to transfer the manure to a manure spreader, flow control valve 10 is closed and the third control~ ~;
; 25 valve 12 is opened and the fourth flow control valve 19 connected to stub pipe 18 is also opened. Under this setting of the valves the manure slurry cannot flow through pipe 3 to .
agitator nozzle 4 and consequently flows through f~ow control valve 10, pipe 11, the lower section of pipe 13, stub pipe 18 and valve 19 and is discharged to the manure spreader through spreader fill pipe 20.
. ' , '.
3~
In severe cases of crust buildup, if not already . ' assembled with tank l, the upper or over the top section of ' pipe 13 is connected to the lower section of pipe 13 which has been connected to the third control vavle 12 to carry manure slurry to spreader fill pipe 20. The connection is made through the quick disconnect coupling tube 16. In order to discharge manure slurry over the top of the tank the second flow control valve lO is closed to prevent flow through pipe 3 to nozzle 4 as is the four-th flow control valve l9 con~rolling flow of the manure slurry to spreader fill pipe 20. With pump : 6 in operation manure slurry then flows from ga~e valve 8, , :
through pipe 7, the first control valve 9 which has remained .
open, thence through pump 6 into pipe 5 and through the third control valve 12 by means of pipe ll. It then flows through the lower sectiorl of pipe 13 to quick disconnect couplin~ tube 16 and the second sectlon of pipe 13 for discharge through nozzle 14 into the crust formed in the top of the tank which is broken up as the upper section of pipe 13 and thus nozzle 14 are manually rotated to the position selected by the lever 17, It is contemplated that the first, secon~ third and ~:~
fourth control valves may be incorporated in a single valve ; body with at least three ports to operate in the same manner as the three control valves 10, 11 and l9 described and shown ' in the drawings which would then be eliminated. ~ ~:
The agitator assembly has a number of advantages. ~ .
Controls are accessible at ground level and no climbing is necessary. The positive shut,off valves 9 and lO allows comple-te drainage of the exposed.pump and conduits in the winter therebyprotecting the equipment from freezing by any manure slurry which may be left inside pipe 5 and pum-~ 6. The :
approach of agitating from the center requires half the pumping distancel more effective mixing and blendi.ng and cleaning out of a tank particularly of large diameter.
The crust problem is also overcome by being able to at-tack it from the top.
