Description

Technical area

The present invention relates to a sieve system according to the preamble of claim 1.

State of the art

There are already known from the prior art sieve systems which have a filtration field movably arranged on a guide frame to remove components from a flowing medium, in particular wastewater, the wastewater flowing through the filtration field in the form of a rake or a sieve, with which coarse Ingredients are retained. The main disadvantages of known systems, however, are that the use of sieve screens in the inlet area of channels that can be fed vertically with a filtration field is only possible with considerable design effort and maintenance or repair during operation is not possible at all due to such structures. Furthermore, known sieve systems of this type require mechanical cleaning, are limited in their area of application and do not offer any modularity.

Presentation of the invention

The present invention is based on the object of creating a sieve system which eliminates the aforementioned, which is structurally simple and flexible in its handling and maintenance. Furthermore, the sieve system according to the invention should make it possible to cover different areas of application due to the design.

According to the invention, the above object is achieved according to the preamble of claim 1 in conjunction with the characterizing features. Advantageous refinements and developments of the sieve system according to the invention are specified in the dependent subclaims.

According to the invention, a sieve system of the type mentioned at the outset is characterized in that the filtration field can be lowered on at least one guide track of the guide frame within a defined channel area, on the guide frame at least one further can be arranged above the first filtration field and on the at least one guide track of the guide frame it can be lowered into the channel area Filtration field is provided, wherein the first filtration field is arranged in a lowered position against the flow direction of the medium to be screened pivotable, displaceable and / or displaceable on the guide frame, wherein the further filtration field can be brought into a position behind the first filtration field and the first filtration field is attached the at least one guide track can be conveyed upwards out of the channel area after the further filtration field has been positioned behind the first filtration field.

In an advantageous embodiment of the invention, in the basic position at the bottom of the channel, the active filtration field with preferably pivoted blade field segment is in use. For evacuation, the active filtration field is advantageously pivoted or pushed into a front guide track facing the flow or brought in some other way and the subsequent filtration field is moved into the basic position, which enables permanent operation even during this process. The active filtration field is then brought up for maintenance, repair, replacement or other purposes. The active filtration field can then be emptied, for example via a discharge flap or a funnel, and cleaned depending on the purpose or type of construction. For example, a kind of "car wash" can be attached.

Implementation of the invention

How out 1 the filtration field can be seen 11 ' on a guideway 100 " of Guide frame 10 with a (maintenance) housing / cladding 102 within a defined channel area K lowerable. On the guide frame 10 according to 1 is at least one more above the first filtration field 11 ' can be arranged and on the at least one guideway 100 " of the guide frame 10 in the canal area K Lowerable filtration field 11 " intended. The first filtration field 11 ' is there - like out 2 can be seen - in the lowered position against the flow direction of the medium to be screened pivotable, offset and / or displaceable on the guide frame 10 arranged. It can also be seen that the further filtration field 11 " to a position behind the first filtration field 11 ' bringable and the first filtration field 11 ' on the at least one guideway 100 " after the positioning of the further filtration field 11 " behind the first filtration field 11 ' can be conveyed upwards from the channel area, where in this embodiment it is within a further guideway 100 ' towards the housing 102 can be transported for further handling (maintenance, cleaning, repair, etc.).

As from the 1-3 can be seen, have at least two filtration fields 11 ' , 11 " advantageously at least one lower hinged filtration area 110 for cleaning the bottom of the canal area and taking loose filtration material or non-adhering, floating filtration material with you after one of the filtration fields has been introduced 11 ' , 11 " can be angled against the direction of flow.

Furthermore, as already described above, a particularly advantageous embodiment of the invention provides that the guide frame 10 at least one guide track facing the flow 100 ' and an upstream guideway 100 " comprises, the filtration fields 11 ' , 11 " for lowering into the canal area via the guideway facing away from the flow 100 " can be guided and via the guideway facing the flow 100 ' can be promoted upwards.

Preferably is in a defined section of the guideways 100 ' , 100 " on the guideways 100 ' , 100 " leading connecting, angled guideway section 1000 provided by means of which the filtration fields 11 ' , 11 " from one guideway 100 ″ to another guideway 100 ' are feasible (see in particular 2 ).

In a particularly advantageous embodiment of the invention is on the guide frame 10 at least one transport carriage 12th provided by means of which the filtration fields 11 ' , 11 " on the at least one guideway 100 ' be carried up and / or down. Of course, the filtration fields come to the conveyance 11 ' , 11 " other support measures such as rope or chain hoists are also considered.

The at least one transport sledge 12th preferably has one or more retaining organs 120 for the reversible arrangement of the filtration fields 11 ' , 11 " on which an alternating acquisition of the filtration fields 11 ' , 11 " both within the guideway facing the flow 100 ' as well as within the guideway facing away from the flow 100 " allow.

For this purpose it is also conceivable and advantageous that the at least one transport slide 12th and / or part of the at least one transport carriage 12th with the at least one holding member 120 and / or the at least one holding member 120 pivotable in the direction of the filtration fields 11 ' , 11 " is / are.

The at least one transport slide is particularly advantageous 12th guided on its own guide track 100 ''', which between the guide tracks 100 ' , 100 ''' runs.

The sieve system according to the invention 1 is not limited in its implementation to the preferred embodiments specified above. Rather, a large number of design variations are conceivable, which make use of the solution shown even if the design is fundamentally different.
