The invention "relates to a Torrichtuag ama Atifereit a spaisabhebendea Torgasg beautster and with lifted material parts near Te ^ mieeliter liquids"

Removal of material particles SoB «produced in a spaaabhebeadea Yorgaag, of chips and / or abrasives _9, hereinafter also referred to as solids ₉ from the liquids used for the machining of metals 2oB _H cutting =

In the filter, regardless of its degree of difficulty, constant, complicated maintenance procedures have to be "turned around", the costs of installing a filter system with a cone device and the costs for maintaining the inlay. are therefore

The Heinigungswir & clothes ron Magnetabsoheidem is primarily due to the removal ferromagnetiseher substances It limited Hei nigimgswirkung of Deikantiersentrifugen iat only for small aäizen in unit time satisfying _s because a rope aiisgesehiedenen from the Plüssiglceit Peststoffe or! _S is supported particles back out "as soon as the _Zait? in which the liquid remains in the _centrifuge's an iron of the respective cable Marriage size of the solids-dependent value under stride to the SehwerJcraftabsoheidung in Jkbsetsbehältera is Terhältnismäßig much-place "requires also Eeiniguzigswirkung is not particularly good _o

Because of the size of the known systems, these are generally arranged centrally »Here, part of the stream _{9 is} that there are already solids in the supply lines ^ Yentils 12 and Swish containers, the removal of which is very laborious there»

The erfinduiigsgemäßs device sum processing of fluids of the aforementioned Irt is characterized gekennteiehnet _p that they sum of the liquid to be treated in a the Mehrsahl the material particles burn a hydrocyclone containing pasty mass and contains in eine.flüssigkeit ₉ further comprising a feed pump connected to the cyclone through a conduit ^,. a dem

The processing of liquids used in machining is made easier and cheaper by the fact that hydroayclones are arranged in the devices according to the invention ₉ in which at least the parts that wear off can consist of an abrasion-resistant solid material ₉ S ₀ B ₀ hard rubber polyamide, polytetrafluoroethylene ₉ ! Cyclones are verhältnismäSig easy and cheap hersustellend © elements »By Inwen ·" dung of a cyclone it is possible *, the liquid continuously purify "A cyclone needs Terhältnismäßig little Plats ₉ so that the entire Keinigungsvorrichtung fails to save space and therefore placed directly on a processing machine can »With a hydrocyclone, the pesticides accumulate in a 3? form that is easy to transport,

The devices according to the invention can be used either to clean liquids contaminated by chips and other solids, or to _{recover the solids 9,} in particular abrasives _{9, or the like}

For oily! Liquids ₉ as processing used especially in iie ~ tallbea3? Weräen ₉ is vfegezi the aging of these fluids rapid Seinigung as si © special with the inventively designed devices mcglioh ^ -From Meaning * The lestteilehen in Flüssigkeit.befindlichen that is to say accelerate the aging of the oil. Liquids which have been purified are therefore more usable than liquids in which solid particles remain for a longer period of time.

Vorriehtuagea with HydrosyHoaea stnä especially £ üs> those of heterogeneous Liquidseap SoB _o emulsions ₉ suitable? 2e & trifuge are not usable for the distribution of such _{liquids P} because heterogeneous liquids iron the strong sentri = * fugal forces in the centrifuge into their individual liquid components »= - ■ The heterogeneous liquid exiting the cyclone has the same degree of mixing, however at the inlet 5, so that with the aid of a device containing a cyclone solid particles can be separated from liquids which are composed of two or more components

If the output of one cyclone is insufficient, several cyclones can be connected in parallel within the same device will",

Since the hydrocyclone aur additional precipitation of Fluid = ness nachgesehaltet from the slurry sine Irish device and the precipitated it! Liquid eye directs the inlet of Hydrosyklons back _nine is emerging from the underflow opening of the cyclone liquid content nioht _a lost The supply of this liquid fraction sum The pump sump enables any solid particles that may still be carried along to settle

If the viscosity of the working fluid to be _{cleaned is too high p to} achieve a satisfactory flow rate and degree of settling su ^ the fluid can be heated to increase the cleaning effect before it is fed into the cyclone.

Sine the invention lies in the fact ₉ that-siefr in the hydrocyclone to a cylindrical Surehflußkammer with 'tangentia ~ lem inlet followed by a pointed cone and the height of the influx = · chamber and at a radial distance from its country a top at its end © with the Chamber wall connected inner sylinärische!

As a result _? that the liquid flowing into the cyclone is transferred from a boring, round cross-section _n as it is used for pipes in the Hegel ₅ into a channel or a boring with a flat, rectangular cross-section _{9 it} receives one _: for the inflow of the liquid into a cyclone be favorable sighting "the liquid is already in the run in reviewing the Zylinderwssid 'pipe section, a swirl _s issued which Yerwirfoe = * ments in the liquid containing pleasurable rode off the rectangular mouth of Sohres ¥ ermieden» ■. ^: ^ -y. ^: - "- ^: c_ ..

In fig ο 3 a ZyKLon 20 is shown, which is fed with the help of a pump 22 via an inlet line 24 _a Aus, an outlet line 26 for the cleaned liquid leads out of the cyclone «, at the bottom of the cyclone there is an underflow opening 28 ₉ to which a container 30 is connected _? There is a screw conveyor 32 at the bottom of the container for discharge of solid particles separated from the liquid. Between the container 30 and the screw conveyor 52 there is a flap (not shown) that can be opened and closed 54 arranged _s that with the inlet of the Puaipe 22 via a line 3S ¥ © i% and @ H ILS ito

The pulpy mass emerging from the underflow opening 28 arrives in the container JO ₉ where the solid particles settle downwards and the liquid collects over it. The solid particles are discharged by the screw 32 and into a carriage 38 conveyed ₉ while the liquid runs over the edge of the container 30 ₉ into the collecting vessel 34 and from there flows through the line 36 into the inlet of the pump 22 "

In the second embodiment according to Pig »4 is below the Syklojis 20 an inclined vibrating screen 40 over a container 42 arranged j, which via the line 56 with the inlet of the Pump® 22 is connected «, the emerging from the underflow opening 28 pulpy mass is converted into a liquid component with the help of the vibrating sieve and a portion of solid particles separated These arrive on the inclined vibrating screen 40 in the Car 38o Me liquid flows through the vibrating sieve 40 hinduoh in the container 42 and is τοπ there in the line 36 sur 'pump guided

The third embodiment according to Fig. _C. 5 differs from the first one in that it has a different design, here with 44 beaeiciiGetea collecting container ₉ which tapers conically at the bottom and is equipped with a tap for drawing off the separated pesticide particles. Inside the collecting container 44 there is an over-

The solid particles are attached to the Έ & ηδ. of the centrifuge container, while the liquid, which is essentially free of the solid particles, is thrown over the walls of the centrifuge container into the container 54. From there it flows to the pump 22 via the line 36 . The centrifuge container must be cleaned from time to time.
