Description
"AIR CLEANER"
The present application relates to an air cleaner intended for separating air from particles or contaminants, mixed into the air, having greater density than the air, and for leading away the cleaned air.
In such apparatus as for example milking machines, by which a rotary pump, which is lubricated with a suitable oil, produces the vacuum needed for the milking process and by which the air is vented after having been used, this air is mixed or contaminated with said lubricating oil. Consequently the air should be cleaned before being let out into the surrounding - atmosphere. This is because other environmental problems will occur, especially as contamination of the subsoil water during several years of discharge as well as in densely built-up areas, which may have similar mach~nes, can be considerable.
A number of different constructions of air cleaners for the above mentioned purpose are prevlously known. However, for a number of reasons these previously known air cleaners have not shown themselves to satis~y the necessary requirements with regard to effectiveness- of the cleaning of the discharged air. The known air cleaners are provided with filtering means, in which the heavier substances are meant to be absorbed and later on these substances are removed together with the filtering means since the filtering means have to ~e exchanged with new ones after some time. In practice this work is not done until the filtering means are so saturated by said sub-` stances that the discharged air is not cleaned at all, which ~` means that the air cleaners from time to time are not operat-ing properly.
There are also known air cleaners which include a vessel in which a number of discs are inserted in order to form passages through which the air is passed. The contamin~
ants will adhere to the surfaces of the discs and will run -` from the d~scs and fall to the bottom of the vessel while the ^~ 35 cleaned air is passed out through the top of the vessel.
An o~ject of the invention is to improve the separating effect of air cleaners having discs.
.
.
A second object of the invention is to make is possible to clean the discs without disconnecting the cleaner from the piping which it serves.
The air cleaner according to the present invention comprises S a container, in which separatinq m~eans are provided for separating said air and said contaminants from each other/ whereby the con-tainer is provided with one opening for discharge of completely or partially cleaned air after passage of the air through the separat-; ing means, whereby centrally in the container is ar~anged an elon-gated inlet tube, which passes through said separating means and has an outlet opening inside the container and whidh is arranged to be connected to said discharge outlet, and that the container is divided by means of a perforated partition into, on one side, an air chamber, for contaminated air and, on the other side, a sub-stance chamber, whereby the arrangement is such that the substance ` or contaminant(s) will undergo a primary separation at said partition and flow down into the substance chamber, under the influence of pressure from the contaminated air within the air chamber.
The air cleaner is characterized in that said separating means comprises a number of funnel-shaped discs, which are piled above each other with a gap between and which are provided with a number of openings for the passage of partially cleansed air, said openings ~~ of one disc being out of the line with corresponding openings of adjacent discs.
An embodiment of the present invention is more fully described below with reference to the accompanying drawing.
FIG. 1 is an elevational perspective side view of the embodi-ment, partially in section, having arrows drawn in continuous lines indicatinq the completely or nartiallv cleaned air and arrows drawn in broken lines indicating the air contaminating substances, such as oil for example.
F~G. 2 is a plan view of a part of one of the separating means.
The container is generally shown by 10 as an elongated contain-er which can be mounted vertically and be connected to a pipe being passed by air which is contaminated with substances or particles of '!
a substance. The container 10 is preferably made of sheet-metal or plastic material, and the cross-section : , .

of same is preferably circular with an open upper end. At its lower end portion 10" the container 10 is funnel-shaped and provided with an outlet, while the rest of the container 10 has a cylindrical form. In the transition between the cylin-dricalpart 10' of the container and the conical part 10" ofthe container, it is arranged and rigidly held a perforated disc 11 in the container, which is placed in the transverse direction of the container in such a way that it divides the container into two chambers, one of which will be referred to as air chamber 12 and is situated at the cylindrical part, while the other will be referred to as su~stance chamber 13 and is situated at the conical part.
The container 10 has a cap 14 covering its upper end which is open. The cap has an inlet 15 in the form of a pipe part. The pipe part 15 leads to a vertical tube 16, which is placed in the centre axis of the container 10~ The tube 1~
has its mouth at a small distance above the disc 11. The cap 14 has also a hole 17 to which 2 second pipe part 18 is connected. This pipe part 18 forms the outlet 19 for the cleaned air. The cap 14 is fastened by suitable means to the container 10, 50 that the connection between the cap and the container is air-tight.
-~ The conical part 10" of the container 10 at its bottom - part is provided with a controllable outlet valve 20, to ~- 25 which a tube can be connected for discharge of oil or other possible contaminants.

The separating means for final separating of the air and the substances are comprised of a number of ~unnel-shaped and circular, relatively thin, discs 21 made o~ sheet-metal or plastic. Each disc 21 is provided with a numher of triangular openings 22, which are arranged at equal distance from each other. Each disc 21, at its circular inner edge has a verti-cally and downwards pointing support ~lange 24. ~he support - flanges abut on the tube 16. Each disc 21 at its outer edge 35 portion is provided with a number of studs 25 which are directed downwards and rest on the upper sur~ace of an under-laying disc. The inner side of the support flange 24 of each of the funnel~shaped discs 21 is intended to rest against the ....

outer side of the centre tube 16, while the outer edge o~ the discs 21 are arranged to span against the inner side of the cylindrical part 10' of the corltainer 10. The discs 21 are fitted into a pile on the tube 16 and the surfaces of the discs are directed obli~uely upwards from the tube 16. A
retaining ring 23 on the end of the tube 16 prevents the discs from slipping off the tube. The discs are arranged above each other in such a way that the openings 22 in every other disc are not brought in front of each other.
As already explained the perforated disc 11 is placed under the mouth of the centre tube 16. The disc 11 has a conically formed upstanding part 26 in its centre. This part has a wing 27, which divides the conical part in two identical parts. The width of the base of the conical part 26 as well ; 15 as the length of the wing 27 correspond to the diameter of the centre tube 16. The wing 27 and the conical part 26 direct the air stream along the upper surface of the perforated disc `: 11.
The air cleaner according to the invention works in the following manner:
When air, which is contaminated with e.g. particles of a lubricant as oil, is introduced by pressure through the inlet 15, the air is then forced through the centre tube 16 into the air chamber 12. The greater part of the oil, having greater density than air, is hereby directed towards the perforated disc 11, whereby said oil is separated from the air and will rùn or drip down through the holes in the disc 11 to ~ ~he substance chamber 13. The partially cleaned air in the , ; air chamber 12, being pressurized, is then forced through the openings 22 of the discs 21 and the gaps between the disc and further on through the hole 17 and out through the outlet 19.
` The remaining part of the oil, i.e. that part of the oil which .,i is transported together with the pressurized air in between the discs 21, runs down along their surfaces and openings 22, ~, 35 to the perforated disc 11 and through it, when the air in the air chamber is not pressurized. In this way the discs 21 are cleaned automatically. If a tube is connected to the outlet valve 20 the oil can be lead into a receptacle for later reuse.
