Description

Przedmiotem wynalazku jest urzadzenie do usuwania olejów i cieklych tluszczów z powierzchni cieczy, stosowane zwlaszcza do usuwania, wydzielanej uprzednio w sposób mechaniczny lub chemiczny, warstwy oleju, cieklego tluszczu badz innej cieczy, plywajacej na powierzchni wody lub scieków. Urzadzenie znajduje zastoso¬ wanie zarówno w zbiornikach dwucieczowych instalowanych w oczyszczalnikach scieków, garazach, myjniach samochodów, tloczniach gazu, jak równiez w naturalnych zbiornikach wody.The subject of the invention is a device for removing oils and liquid fats from the surface of a liquid, used in particular to remove a layer of oil previously released mechanically or chemically, oil or any other liquid that floats on the surface of water or sewage. The device is used both in two-fluid tanks installed in sewage treatment plants, garages, and car washes cars, gas compressor stations, as well as in natural water reservoirs.

Do usuwania warstwy oleju lub cieklego tluszczu z powierzchni wody lub scieków, znajdujacych sie w zbiornikach dwucieczowych, stosuje sie przelewy, które umieszczone sa przewaznie na podluznych sciankach zbiornika powyzej normalnego zwierciadla cieczy hydrofilowej. Zamkniecie zasuwy na odplywie cieczy hydrofi- lowej powoduje jej spietrzenie powyzej krawedzi przelewowych i odplyw warstwy tluszczowej do oddzielnego zbiornika. Do usuwania olejów i cieklych tluszczów ze zbiorników dwucieczowych stosowane sa równiez pompy wirowe i wyporowe. Z uwagi na rózne lepkosci cieczy zawartych w zbiorniku, pompy zasysaja usuwany olej, jak równiez ciecz hydrofilowa, co wymaga ponownego ich rozdzialu w dodatkowych zbiornikach. Stosowanie pom¬ py do usuwania olejów i cieklych tluszczów daje pozytywne wyniki jedynie przy duzej grubosci ich warstwy, wynoszacej okolo 1 m, co w praktyce jest rzadko spotykane. Ponadto nawet tak duza grubosc warstwy hydrofo¬ bowej nie zapobiega tworzeniu sie leja depresyjnego, którego os jest zblizona do osi zanurzonego w cieczy przewodu ssawnego pompy, co utrudnia usuwanie samej warstwy hydrofobowej, bez jednoczesnego zasysania cieczy hydrofilowej.For removing a film of oil or liquid grease from the surface of water or waste water in two-fluid tanks, overflows are used, which are usually located on longitudinal walls reservoir above the normal table of hydrophilic liquid. Closing the shutter on the outflow of hydrophilic It causes its damming above the overflow edges and drains of the fat layer into a separate one tank. Pumps are also used to remove oils and liquid fats from two-fluid tanks vortex and displacement. Due to the different viscosities of the liquids contained in the tank, the pumps draw in the removed oil like also a hydrophilic liquid, which requires their redistribution in additional tanks. Using the pump dust for removing oils and liquid fats gives positive results only with a high thickness of their layer, about 1 m, which is rare in practice. Moreover, even such a high thickness of the hydrophobic layer bowa does not prevent the formation of a depression funnel, the axis of which is close to the axis immersed in the liquid suction line of the pump, which makes it difficult to remove the hydrophobic layer itself, without sucking at the same time hydrophilic liquid.

Istota wynalazku polega na usuwaniu olejów lub cieklych tluszczów za pomoca urzadzenia skonstruowane¬ go w postaci przenosnika tasmowego z tasma o obiegu zamknietym, która wyposazona jest w element chlonny o strukturze gabczastej. Tasma przenosnika wspólpracuje z urzadzeniem wyciskajacym ciecz hydrofobowa z ele¬ mentu chlonnego, wykonanym w postaci walka dociskowego lub korytka dociskowego ze scianka perforowana.The essence of the invention is the removal of oils or liquid fats by means of a device constructed it in the form of a belt conveyor with a closed-circuit belt, which is equipped with an absorbent element with a spongy structure. The conveyor belt cooperates with the device for squeezing the hydrophobic liquid from the gel absorbent material, made in the form of a pressure roller or a pressure tray with a perforated wall.

Urzadzenie wedlug wynalazku posiada szeroki zakres zastosowan, gdyz charakteryzuje sie mozliwoscia dostosowania do wspólpracy z róznego rodzaju zbiornikami odolejania, jak równiez moze byc montowane na jednostkach plywajacych w naturalnych zbiornikach wody. Urzadzenie jest napedzane recznie lub mechanicznie,2 96079 w zaleznosci od dorywczej lub ciaglej pracy urzadzenia. Ponadto charakteryzuje sie ono prosta konstrukcja oraz eliminuje odprowadzanie cieczy hydrofilowej, usuwajac skutecznie warstwe hydrofobowa.The device according to the invention has a wide range of applications as it is characterized by capability adapted to work with various types of de-oiling tanks, as well as can be mounted on vessels floating in natural water reservoirs. Unit is manually or mechanically driven, 2 96079 depending on the occasional or continuous operation of the device. Moreover, it is characterized by a simple structure and eliminates the discharge of hydrophilic liquid, effectively removing the hydrophobic layer.
