Description
`Patented July 28, 1931 PATENT oFFlcuf IGZNLAZrv SABLIK, OF S'IRAMBERG, CZECHOSLOVAKIA LIQUID FEEDING APPARATUS appli-cation fuearaaaaryki, 193o,.sar`ia1 1vo.41s,457, and in Czechoslovakia January 19, 1929.
This invention relates to a method of feeding liquids composedv oly certain chemical elements, 'orl containing solids in suspension.
, ,y Gen's'i'derable-troubleis caused in feeding liqnids containing certain elements dueto their corrosive action oli/the reciprocating orA theV rotary parts ofy the pump. Also diihculty is lenc'ountered'whenL feeding liquids containing ,s solids` in! suspension, dueftoy clogging of the 117 part-'s ofthepumpwith `which it contacts.`
@ne of the objects of this: invention is to Y overcomefthesediiiiculties by providing an improvedi'method oli'feeding liquids com-y posed., of certain chem-ical elements or con- I5f taining solidslinrsuspension, so that the liquidi tofbe fedi doesfnotfcome in contactwith either the4 reciprocating or the rotary parts ofthe pump. f
, 4 Another objectief the inventionL is to pro- 201 vide an improved and simple valve-operating mechanism for feeding liquids wherein the direct influence of airpressureo variable trength is utilized` in: moving the fluid to be ed. f This is accomplished by providing two reservoirs each fitted with a suction connection to the liquid to be fed, and a connection for discharging the liquid. These reservoirs yare alternately and by turns connected to the suction and pressure pipes of a compressor, so that when one reservoir is being lilled with the liquid to be fed,the other reservoir is be- Y ing emptied.` In this manner the liquid to be yfed does not come into contact with either 'the reciprocating or the rotary parts of the pump.
Other and ancillary objects of the invention will appear hereinafter. y ,l In the l'z'tccompanying drawings which eni- 'body the invention- Fig. 1 is a front elevation of apparatus enibodying the invention partly in section; andy Fig. 2 isa side elevation of the apparatus of Fig. l.
' Referring to the drawings, reservoirs 1 and 2 are both provided at the bottom with a distributor `3, connected at 4 to the suction piping and at 5 to the discharge piping. The
suction piping l is connected to the liquid to befed, which liquid is discharged ythrough the discharge piping 5 to the place whereit'r is desired to feed theliquid;
Both the suction and discharge pipingy contain appropriatemenibers not shown, al`-v lowing the passage of the liquid in one direction only. In the top of reservoir 1 is shownv a branch of pipe 6- which connects withreser'- voir 2 through a branch 7 andY valve 15. Inl both reservoirs are located the floats Sandi 91 having a central opening 10 which slides upon the guide rod 11. Their the reservoir is empty the float is supported onV the guiderodA stop 12, but when the reservoirl isbeing filled, the fioat is lifted by the liquid'A and'L rises until it strikes a disk 13, securedf' to the guide-rod and lifts the rod. On the upper end of the' guideis secured the valve 14, so that thev lifting of this rod seats the valve' and closes the reservoir from the/line 6. Similarly the float 9, in reservoir 2, disconnects this reservoir from the branch.v 7. Each reservoir can be connected alternately to a vsuetionli'ne 116er to a pressure'line 1710i' ay conipressor system, by means of a two-way valve 135" lVith either onev ot the reservoirs filled! andl thevalve 14 seated, it pressure is exerted above the valve, from the pressure line 17, the valve will be unseated: andy the liquid forced from thereservoir so as-to enter the discharge pipe 5 through the distributor `3'. By means of the twoway valve 151, and itsv connections,` hereinafter described, while the one reservoir is being emptiedi by the pressure from the pressure line,`the other reservoir isconnected with the suction line 16, and is being filled.V
The two-way valve 15 is operated by; thel piston' 18 of the pressure cylinder'll')I through the lever 20- which is fastened tothe valve- Bothv sides of the cylinder 19 are connected with thekk compressor system and tothe pres-l sure line, by means of a pipe 21, and the an-A nular pipe 22. In order that thel pistonfl may operate and reverse the valve'. 15,the medium; operating in the cylinder must be exhausted above the piston and? at the same time be admitted below the piston and. vice versato reverse it. The control of the medium to cause; reversal is accomplished by means of they valves 23. andi24 insertediin the sov 35i, v -f and discharge openings at the Abottom, suc-VV annular pipe 22. These valves are of the three-way type and alternately allow pressure to flow to cylinder 19 and permit the exhaust therefrom. These valves are operated by the guide-rods 11, through the levers 25 and 26, passing through slots arranged in the guide-rods. secured to the rods 11 andassistthe valve 14- to operate smoothly and elficiently. A check valve 28 is placed between the pressure end 17 of the compressor andthe two-way valve 15 to prevent the compressor medium from flowing back into the system. lNh'en the twoV way valve ljlias reachedthe position in which 'the'reservoir 1 is' to be filled and the' reservoir 2 is to .be'emptied, the medium such as the air carriedby the 'compressor on the suction end, flows inthe direction of the arrowI, and the medium carried on the pressure endkilowsin the direction of the arrow II. When reversalhas taken place the d irection of themediun'i actuated' by the compresser, is shown on the suction end, by the arrow III, and on the pressure side by they arrow IV, Reservoir 1 is thus being emptied while the reservoir 2 is being filled.
Other methods may be used to effectthe reversal ofthe two-way Tvalve- 15, for eX- ample by electricity, controlled by contacts on and-operated by the guide-rods 11. Instead` of one two-way valve inserted between the two reservoirs there-couldbe used two such valves, and even four-governing members could be used as follows: Two, toccontrol the inlet and outlet of one reservoir, and two to1 control theV same valves in the other` reservoir. Y f
While the invention has been illustrated in what is considered its best application-it may have' other embodiments without departing;
from its spirit andis not, therefore, limited to 'the structuresshown inthe drawings.
