GLARIFYING SYSTEM FOR CLEANING FLUIDS.
Application men December e, 1924. serial No. 754,425. x
This invention relates to new and useful improvements in clarifying systems for .cleaning fluids.
In dry cleaning and similar plants, it is customary to use gasoline and kindred detergent liquids to cleanse the articles. It is customary to pump the gasoline from underground storage tanks into the cleaning machine and then drain it back into the tank, more or less effort being made to filter or clean the returned gasoline. Gasoline when purchased by the cleaner contains both water and dirt. The usual practice is to use the gasoline for a period and then discard it. The object of my invention is to provide a system in which the gasoline is clarified before it leavesthe tank, so that clear and sweet gasoline will be supplied to the cleaning-machine; and also to again clarify the 29 gasoline after it leaves the machine and before it is returned to the tank.
Other features of the invention are a filter; a sediment trap in the return line, and eflicient cleanout lines.
A construction designed to carry out the invention will be hereinafter described together withother features of the invention.
The invention will be more readily understood from a reading of the following speci- 30 fication and by reference to the accompanying drawings, in which an example of the invention is shown, and wherein:
Fig. 1 is a diagrammatical view, of the system,
Fig. 2 is a vertical sectional view of one of the auxiliary tanks,
Fig. 3 is a cross-sectional view on the line 33 of Fig.2, I V
Fig. 4 is a cross-sectional view on the line 44 of Fig. 2,
Fig. 5 is a vertical sectional view of the filter, and
. Fig. 6 is a crosssectionalview taken on the line 66 of Fig. 5.
In the drawings the numeral 10designates an underground storage tank having a fillf ing pipe 11 and vent 12. A suction pipe 13 leadsfrom the tank 10 and is connected to a manifold 14. This pipe includes a cut-off 50 valve 15. The manifold is connected with a'pump suction pipe'16 leading down to a centrifugal pump 17. A discharge pipe 18 leads from the pump. A cut-off valve 19 is included in the pipe 16 and a blow-ofi' pipe 20 including a cut-off valve 21, leads from the pipe 18 adjacent the pump.
A suitable cleaning machine 22 is providd, the system being usable with any kind of machine, and a filter 23 is mounted over the machine. A discharge pipe 24 leads from the upper end of the top of the cleaning machine. A screen 25 is fastened transversely across the filter just below the pipe 24 and cotton waste or other filtering material 26 is confined below the screen. The pump discharge pipe 18 enters the bottom of the filterandthe gasoline must .passup through filtering material.
A return pipe 27 leads from the bottom of the machine to the top of a suitable trap 28.
A gooseneck pipe 29 leads from the bottom of the trap up to a distributing pipe 30. The pipe 30 connects with a down pipe 31 extending down into a cone-bottom auxiliary tank 32. The pipe 31 has a four-way nozzle 33 at its lower end confined under a conical screen 34. An overflow by-pass pipe 35 leads from the top of the tank 31 and is connected with a down pipe 36 in a second auxiliary tank 37. The pipe 36 also has a four- .way nozzle 38 confined below a conical screen 39. In the bottom of the tank 32 a solution of five pounds of commercial alkali to fifteen gallons of water is maintained to a level above the screen 34; while in the tank I 37 clear. water is maintained to the same level. A cleanout pipe 40 has its lower end bent and inserted through the screen 34 and extends from the tank 32 to the manifold 14.
.This pipe includes a valve 41. A similar pipe 42 including a valve 43 extends from the tank 37.
In operating the system all valves are closed and the pump 17 is started. Then the valves 15 and 19 are opened whereby gasoline is drawn from the tank 10 through pipe 13, manifold 14 and pipe 16. This" gasoline isdischarged from the pump through line 18 to the filter 23, where it passes up through the filtering material 26 and screen 25 and is thus clarified. -The clean, sweet gasoline overflows from the filter throughthe pipe 24 to the machine 22. After the cleaning is completed the gasoline is dirty and discolored and is conducted by the return pipe 27 to the trap 28. Here the muck and heavy dirt particles are caught, while the liquid passes through pipes 30 nozzle 33 in the tank 32. The dirty and 31 and is discharged in jets from the asoline being discharged in the tank 32 below the screen 34 will agitate the solution therein. The screen will tend to check the agitation and prevent the escape of bits of material and foreign matter into the tank above the solution.
The gasoline being an oil will rise through the solution, but in so doing will be clarified. The accumulated gasoline will overflow into the tank 37 by the pipes 35 and 36. In the tank 37 the gasoline will be thoroughly washed and the clarification completed. When it is desired to supply to the machine 22. again, the valve 15 is closed and a valve 44 in a pipe 45 is opened. The pipe 45 draws the clarified gasoline from the tank 37 to the manifold 14 from which it is conducted by the pipe 16.
When it is desired to clean out the tanks 32 and 37 the valves 41 and 43 are opened so that the water, clarifying solution and dirt may be sucked up through the pipes 40 and 42 to the manifold 14 by the pump 17 and discharged from pipe 20 by open ing the valve 21, the pipe 16 conducting the liquid from the manifold to the pump. I also provide for attaching a steam line 46 to the end of the manifold and control the same by a valve 47. Byproperly handling the valves steam may be introduced through the pipes 40 and 42 to clean out the tanks 32 and 37; after which the steam is cut ofi and the same pipes used to remove the dislodged matter.
Various changes in the size and shape of i the difierent parts, as well as modifications and alterations may be made within the scope of the appended claims.
What I claim, is:
1. In a detergent liquid clarifying system, a cleaning machine, a'storage tank, a connection between said tank and machine, means in said connection for forcing liquid from the storage tank to the machine, an
- auxiliary washing tank having a screen at its lower portion, a discharge connection extending from the machine to the washing tank beneath said screen, a return connection from the upper portion of said washing tank to the liquid forcing means deliver-- ing to the machine, and means for removing material from beneath the screened portion of the washing tank.
2. In a detergent liquid clarifying system, a cleaning machine, a storage tank, a connection between said storage tank and cleaning-machine, means in said connection for forcing fluid from said tank to said machine, a pair of auxiliary washing tanks, a pipe leading from the cleaning machine to the lower portion of one of said auxiliary tanks, a pipe connection from the upper portion of the last mentioned tank to the lower portion of the other washing tank, a pipe extending from the upper portion of the second washing tank tothe fluid forcing means, and means for removing collected material from the base of said washing tanks.
3. In a detergent liquid clarifying system, a cleaning machine, a storage tank, a connection between said storage tank and said cleaning machine, a pump in said connection, first and second auxiliary washing tanks, a pipe connecting said cleaning machine with said first auxiliary tank, a pipe establishing communication between the upper portion of one washing tank and the lower portion of the other washing tank, a pipe from the latter tank delivering to the machine, and pipes leading from the lower portion .of both of said tanks and connected with said pump.
4. In a detergent liquid clarifying system, a cleaning machine, a storage tank, a communication between said storage tank and said cleaning machine, a pump in said communication, first and-second auxiliary washing tanks connected to each other, a pipe connecting said cleaning machine with the first of said tanks, pipes connecting both of said auxiliary tanks with said pump, and an"additional pipe establishing communication between the second of said auxiliary tanks and said pump to deliver to said machine.
