1 Claim.
This invention relates to pumping systems such as those employed in the copper, zinc, and other similar mining industries, for circulation of dilute sulphuric acid or other acids, in leaching or electrolytic tanks.
Heretofore pumps of the type known to the trade as bootleg pumps, because of the long boot which forms the suction chamber, have been employed in such service, in connection with a level control tank interposed between the main collecting tank and the pump. While such pump constructions and systems have in the main been successful .1 operation, they are costly both as first cost and as to maintenance, partly due to the inaccessibility of and the difficulty in dismantling the pump boot to gain access to the pump impeller and casing for repairs thereto or for releading.
An object of the present invention is to provide a pumping system and structure for use in install ions of the above or analogous type which will reduce both the initial or manufacturing costs, and the maintenance costs of the pumping structure and which will eliminate the inaccessibility and difficulty of dismantling and re-assemb ng the pump.
1" specifically, the present invention comprises the provision of a pumping unit or structure of this type wherein the pump casing is attached directly to the bottom of the level control tank so that a part of this tank will act as the suction boot of the pump. A suitable shaft is provided which carries the pump impeller and is connected by a suitable coupling to the motor driven shaft in such manner that the impeller unit may be withdrawn with comparative ease through a suitable opening in the tank.- The tank also is large enough to admit a mechanic or mechanics, so that the interior of the pump casing may be re-leaded or repaired without disturbany of the piping connections thereto.
With these and other objects in view, as may appear from the accompanying specification, the invention consists of various features of construction and combination of parts, which will described in connection with the accompanying drawings, showing a pumping system embodying the invention, and the features forming the invention will be specifically pointed out in the claim.
In drawings:
Figure 1 is side elevation of the improved piping s Vructure.
Figure 2 is a vertical section through the pump proper and a part of the level control tank,
Figure 3 is a plan view taken on the line 3-3 of Figure 1.
' Figure 4 is a detailed section taken on the line 44 of Figure 2.
Figure 5' is a detailed section taken on the line 55-of Figure 1.
Figure 6 is a detailed section taken on the,line 6-43 of Figure 3.
Figure -7 is a section through a part of the level control tank and the pump casing illusl0 trating the manner of removal of the pump impeller unit.
Referring more particularly to the drawings, the improved pumping system includes the pump structure l, the casing 2 of which is attached in any suitable manner to the outer surface of the bottom 3 of the level control tank 4', with the side of the casing open to the interior of the tank, as clearly shown in Figure 2 of the drawings. The pump impeller 4 is carried by a suitable shaft 5 which extends downwardly through the level control tank i. The upper end of the suitable shaft 5 extends out of the top of the control tank 4 through a suitable opening in the removable cover 6, and it is connected to the motor driven shaft l by a coupling 8. In the drawings a particular type of coupling 8 is shown, having one of the coupling flanges, namelythe flange 9, formed upon the shaft 1, while the coupling flange H3 is detachably connected to the upper end of the suitable shaft 5. However it is to be understood that any suitable type of coupling may be employed which will provide positive steady connection between the shafts 5 and l, and permit disconnection of these shafts for the removal of the impeller unit, as will be hereinafter more fully described. The pump structure l, shown in the drawings, is lined with a suitable acid resistant, such as lead and antimony, however, if it is so desired, the pump parts may be constructed of a suitable acid resisting material, instead of lining or coating the pump parts as shown in the drawings. The shaft 5 is also coated with a coating of acid resistant, as shown at H.
Owing to the fact that it is necessary to repair the impeller l and the interior of the casing Z of the pump, a pump structure is provided which will facilitate the removal of the impeller without completely dismantling the pump and without disrupting the connections of the casing with the level control tank 4, and with piping (not shown) which may be connected to the discharge flange it of the pump. The suction side of the casing 2 which opens into the level control tank has its sides tapering outwardly as they eX- 5 tend towards the bottom 3 of the tank 4', as clearly shown at I4 in Figure 2 of the drawings. A removable member I5 is provided which fits in the tapered portion of the pump casing and 5 cooperates with the pump casing 2 and the impeller 4 to form the proper passages in the pump and provide a suction opening or eye l6 for the pump, which opens directly into the tank 4.
The member I5 is held in place by suitable rods l l, which have their lower ends detachably connected to the removable member I5 and extending upwardly through the tank 4 and into suitable sockets l8 formed in the removable covering 6. Set screws l9 are carried by suitable blocks 20, which latter are preferably welded to the cover 6. The set screws l9 engage the upper ends of the rods l1 and clamp against them for securely holding them and the removable member IS in place.
When it is desired to remove the impeller element, comprising the impeller 4, removable member l 5, shaft 5, and rods H, for repair or re-lead ing of the impeller and pump parts, the slide 22 which forms a part of and is slideably carried by 25 the cover 6 is moved outwardly, the set screws [9 are loosened, the cover member 6 is lifted slightly so that it will clear the upper ends of the rods I1, and the cover is then moved into open position as shown in Figure 7 of the drawings. The
As hereinbefore pointed out, one end of the level control tank 4' forms the boot or suction chamber for the pump I, eliminating the need of the boot such as has been previously employed to provide the suction chamber for pumps of this type.
The level control tank 4' is connected to the main collecting tank 26 through a suitable supply pipe 21, and a float controlled valve structure 28 of any suitable type is placed in the piping 21 for controlling the flow of fluid into the level controlling tank 4'. The float 29, which controls the liquid level in the tank 4', is placed in the tank as shown in dotted lines in Figure 1 of the drawings.
The driving motor 30 is supported above the collecting tank 4' on suitable supporting structure indicated at 3| and shims, as indicated at 32 v in Figure 2 of the drawings, may be used for raising the motor structure slightly to permit sulficient separation of the elements 9 and ll] of the coupling 8 to allow the initial movement of the shaft 7, impeller 4, and removable member [5, to allow the removal of these members when desired.
It will be understood that the invention is not to be limited to the specific construction or arrangement of parts shown but that they may be widely modified within the invention defined by the claim.
What is claimed is:
In a pumping structure, in combination, a level control tank, a pump including a casing embodying an impeller chamber and having its suction side open and attached to said tank whereby the tank will act as a suction chamber for the pump, an impeller in said casing, a removable member forming the suction side of the impeller chamber and passages of the pump, a
shaft connected to said impeller, a prime mover,
and removable member and impeller shaft maybe removed from the casing and tank as a unit.
