The coarse separator is provided with insert elements which assist in the separation of the light liquids. The improvement features are that the coarse separator (2) inserts consist of a coagulation device (5), and the fine separator (7) is divided by a e.g. a wall (8) into two chambers, in the downstream chamber of which is a removable container (9) for a filter material such as mats of expanded or foamed material, activated carbon etc.. Pref. the filter container (9) is open at least on one side, and a wall is provided at a distance from this open side. The container may be provided with guides into which this wall is fitted. USE/ADVANTAGE - Used for sepg mineral oils from liq in a process which includes a pretreatment of the contaminated liquid. Different filter materials, such as mats of expanded or foamed filter material or activated carbon, can easily be used. The intensity of cleaning can be regulated by the use of filter materials with different pore sizes. Excess oil is readily removed from the filter container.

Description

Light liquid separator

Technical field

BACKGROUND OF THE INVENTION The present invention relates to a light-liquid separator in which settles are separated in a coarse separator and light liquids which have floated to the surface are separated in at least one fine separator downstream thereof, the coarse separator being provided with inclusions. coarse separator.

BACKGROUND OF THE INVENTION

Although known separators for separating light liquids can guarantee sufficient cleaning of the liquid to be cleaned, the cleaning effect is only achieved in complicated ways.

Furthermore, it is not easy to ensure that various filter materials, such as foamed mats or activated carbon filters, can be used. The use of foamed mats with different pore sizes is already problematic in order to control the cleaning intensity.

Furthermore problematic removal of excess oil from the filter containers. ......

SUMMARY OF THE INVENTION

The aforementioned drawbacks are eliminated by a light liquid separator in which the coarse separator separates sediments and at least one fine separator downstream of it separates the light liquids that have floated to the surface, the coarse separator being fitted with inclusions. of which the light liquids are already separated in the coarse separator according to the invention.

wherein the fine separator is further divided into two spaces by a submersible wall or the like, and in the second space downstream of the first space there is at least one extractable container containing filter material, such as foamed sheets, activated carbon filter or the like.

*

Thus, in the solution according to the invention, the contaminated liquid in the filtration complex enters the upstream chamber in which the sludge settles and the liquid to be cleaned is cleaned by a coagulation device.

In this pre-chamber, the liquid reaches the second chamber in the second chamber, in which the immersion wall and the combination vessel with coagulation and absorption filters are provided, by means of a dip tube with an automatic float seal.

An ideally positioned side-mounted, retractable immersion wall flows the liquid to be cleaned tangentially into a container with coagulation and absorption filters for optimum cleaning performance.

Different filter mats can be used in the present invention, thus allowing optimum cleaning control. However, these filter mats can be replaced very easily, so that foam mats of different pore sizes can be used as desired, or filter mats of other materials can also be used. Therefore, it is also possible to use, for example, activated carbon mats.

Coalescence is simplified by the free-rising water columns and the cleaning effect is therefore increased. By arranging the outlet pipes as quick drain pipes, the filter cartridge can be removed and replaced without much effort. In the inserted state, these pipes are sealed downwards for rapid drainage, for example by means of a rubber sealing plate. Upon withdrawal of the filter element, however, liquid is allowed to flow out through the outlet pipe. Upon lifting, the connection between the filter mat and the outlet pipes is broken so that the outlet pipes are no longer sealed by the rubber sealing plate and the liquid can leak out.

The coalescing interspace ensures uniform flow. This even flow guarantees optimum cleaning. However, it is also possible to fill the chamber with wire mesh inserts.

In particular, the top of the combined coagulation container is provided on the absorbent handles and thus a preferred embodiment of the invention, and an openable lid is provided by the filters. The oil drain plates * can be pulled out to the side and the oil can drain freely as required.

According to a very advantageous embodiment, said handle for the container housing is disposed transversely on the container so that the removal, but in particular the reinsertion of the filtering means is greatly facilitated. cabinets. For other mounting, such a handle. In any case, it would be possible to "insert" the filter housings, but these filter housings would be allowed. they could jam in the filter tank ..

BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be explained in more detail by way of example with reference to the accompanying drawings, in which: Figure 1 shows the entire light liquid separator in plan view;

FIG. 3 shows a section A-A of the light-liquid separator according to the invention. FIG. 3 shows a combined container with coagulation and absorption filters in section B-B of FIG. 4 and FIG. 4, in plan view.

EXAMPLES OF THE INVENTION

As can be seen from FIGS. 1 and 2, the light liquid separator according to the invention is provided with an inlet regulator χ. Through this supply regulator χ, the liquid to be cleaned flows into the space, representing the coarse separator 2, which is surrounded by the wall 3. Sludge and other substances can settle in the sludge pit 4. The purified liquid is pretreated in a coagulation device By means of an immersion tube with a self-closing cap 6, the pre-purified liquid enters a second compartment, representing a fine separator 7, which is surrounded by the same wall 3 as. The coarse separator 2 is located in this fine separator 7.

The important cleaning of the liquid is carried out in a combined container 9 with coagulation and absorption filters. At the outlet 10, the liquid leaves the system.

FIG. 4 shows only a combination vessel 2 ^with coagulation and absorption filters. This container 9 is formed

In the housing 11. In this housing 11, for example, two filter mats 13 are shown. A submersible wall 14 suspended at the front, which can be pulled to the side, guarantees tangential flow of the liquid to be filtered.

The liquid leaves the combined container 9 with coagulation and absorption filters through the outlet 15.

The rubber, sealing plate 16 and pipe 17 for the rapid flow of water ensure easy removal of the filter element.

Drain plate 18. the oil can be removed by the handle 19. This allows the excess oil to rise.

The handle for the housing 20 is hinged to the housing 20 to prevent the housing 20 from jamming during insertion.

This filter box slides along the guide rails 21 ..

The coalescing interspaces 22 serve for uniform flow and may be filled with wire mesh inserts.
