Filter met continue spoeling, bij voorkeur voor bestrijdings-machines in de landbouwContinuous flush filter, preferably for agricultural pest control machines
De onderhavige uitvinding heeft betrekking op een filter met continue spoeling, bij voorkeur voor bestrijdings-machines in de landbouw, waarvan de ingang met een aanvoer-leiding, de uitgang met een mondstukaanvoerleiding en de in-5 wendige ruimte met een reservoir is verbonden.The present invention relates to a continuous rinse filter, preferably for agricultural control machines, the inlet of which is connected to a supply line, the outlet to a nozzle supply line and the interior space to a reservoir.
Uit het vaktijdschrift "AGRARTECHNIK" (BRD, mei 1986) is een filter met spoeling, bij voorkeur voor bestri jdingsmachines in de landbouw bekend, waarvan het principe is gelegen in het feit, dat zijn ingang met de aanvoer-10 leiding, de uitgang met de mondstukaanvoerleiding en de inwendige ruimte via een afsluitklep met een tank (reservoir) is verbonden.The magazine "AGRARTECHNIK" (BRD, May 1986) discloses a filter with rinsing, preferably for agricultural combat machines, the principle of which lies in the fact that its inlet with the supply line, the outlet with the nozzle supply line and the interior are connected to a tank (reservoir) via a shut-off valve.
Het nadeel van deze bekende oplossing is hierin gelegen, dat het onderbreken van de spoeling geschiedt door het 15 van buitenaf ingrijpen, dat dit ten gevolge van het subjectieve karakter van de capaciteitsverandering van filter ineffectief is, dat dit een bijzondere bewaking vereist en dat het filter derhalve oneconomisch is.The drawback of this known solution lies in that the interruption of the rinse is effected by intervention from the outside, that it is ineffective due to the subjective nature of the capacity change of the filter, that it requires special monitoring and that the filter is therefore uneconomical.
De uitvinding beoogt de bovengenoemde nadelen op te 20 heffen, dat wil zeggen een filter te verschaffen met een continue spoeling, dat wil zeggen met een automatische reini-gingscapaciteit.The object of the invention is to overcome the above-mentioned drawbacks, ie to provide a filter with a continuous rinse, that is to say with an automatic cleaning capacity.
Het doel van de uitvinding is een filter te verschaffen waaruit het vuil automatisch verdwijnt zonder dat 25 het vuil op een ongewenste plaats komt, respectievelijk zonder dat de werking van het filter hierbij moet worden onderbroken .The object of the invention is to provide a filter from which the dirt automatically disappears without the dirt coming to an undesired place, or without the operation of the filter having to be interrupted.
Hiertoe bezit het filter volgens de aanhef het kenmerk, dat zijn inwendige ruimte en het reservoir via een 30 drukregelklep zijn verbonden.For this purpose, the filter according to the preamble has the feature that its internal space and the reservoir are connected via a pressure control valve.
Ter verhoging van de effectiviteit is een uitvoeringsvorm van voordeel, waarbij de inwendige ruimte via een drukregelklep, die aan de tegenover de ingang gelegen zijde is geplaatst, met het reservoir is verbonden.In order to increase the effectiveness, an embodiment is advantageous in which the internal space is connected to the reservoir via a pressure regulating valve placed on the side opposite the entrance.
35 De uitvinding wordt nader toegelicht' aan de hand van de tekening, waarin een uitvoeringsvoorbeeld is weergegeven.The invention is further elucidated with reference to the drawing, in which an exemplary embodiment is shown.

De enige figuur 1 toont op schematische wijze een filter volgens de uitvinding.The only figure 1 schematically shows a filter according to the invention.
De ingang 1 van het filter volgens de uitvinding is met de aanvoerleiding 2 verbonden terwijl de uitgang 3 met de 5 mondstukaanvoerleiding 4 is verbonden.The inlet 1 of the filter according to the invention is connected to the supply line 2, while the outlet 3 is connected to the nozzle supply line 4.
De inwendige ruimte 5 van het filter volgens de uitvinding is via een leiding 6 op een niet getoond reservoir (tank) aangesloten.The inner space 5 of the filter according to the invention is connected via a line 6 to a reservoir (tank) not shown.
In de leiding 6, tussen de inwendige ruimte 5 en 10· het reservoir, is een drukregelklep 7 geplaatst.A pressure regulating valve 7 is placed in the pipe 6, between the inner space 5 and the reservoir.
De werking van het filter volgens de uitvinding wordt hierna nader toegelicht.The operation of the filter according to the invention is explained in more detail below.
De niet gefilterde vloeistof, welke door de pomp via de aanvoerleiding 2 wordt getransporteerd, stroomt in de 15 inwendige ruimte 5 van het filter. Van hieruit komt een gedeelte van de vloeistof via een filtervulling 9 in de mond-stukaanvoerleiding 4, terwijl het resterende gedeelte, dat een gevolg is van het overtransport van de pomp, via de drukregelklep 7, welke op doelmatige wijze aan de tegenover de 20 ingang 1 gelegen zijde 8 is geplaatst, stroomt en via een leiding 6 in het reservoir terugstroomt.The unfiltered liquid, which is transported by the pump via the supply line 2, flows into the internal space 5 of the filter. From here, a portion of the liquid enters the nozzle feed line 4 through a filter fill 9, while the remainder, which results from the pump's over-transport, through the pressure control valve 7, which is effectively at the opposite inlet. 1 located side 8 is placed, flows and flows back into the reservoir via a line 6.
Ten gevolge van de terugstroming van de vloeistof neemt zij het vuil, dat uit de vloeistof werd gefilterd, continu met zich mee, dat wil zeggen dat een continue spoeling 2.5 plaatsvindt.As a result of the backflow of the liquid, it continuously takes along the dirt which was filtered out of the liquid, that is to say that a continuous flushing 2.5 takes place.
De voordelen van het filter volgens de uitvinding zijn hierin gelegen, dat dit zonder uitwendige, op een subjectieve beoordeling rustende inwerking en onderbreking van het bedrijf een voortdurende zelfreiniging garandeert, ter-30. wijl verder de drukregelklep, die overigens toch al noodzakelijk is voor het vloeistofsysteem, door het filter volgens de uitvinding van een dubbele functie wordt voorzien, waardoor de effectiviteit wordt verhoogd, terwijl tenslotte geen extra voorzieningen nodig zijn, zodat het filter verder economisch 35 is.The advantages of the filter according to the invention lie in that it guarantees continuous self-cleaning without external, subjective assessment and interruption of the operation. Furthermore, while the pressure control valve, which is otherwise already necessary for the liquid system, is provided with a double function by the filter according to the invention, whereby the effectiveness is increased, while, finally, no additional provisions are required, so that the filter is further economical.
