Abstract

Liq., esp. a soln. or suspension of plant protection medium used in agriculture, is pumped from a feed pipe in to the cavity contg. a cylindrical filter passed by the liq. into a lateral outlet leading to distribution sprayers. An excess of pumped liq. flows from the axially opposite end of the cavity, past a pressure control valve and into the connector pipe to an external container. Solids deposited on the filter surface are entrained by the surplus flow into the container.

Description

Die vorliegende Erfindung betrifft ein Filter mit kontinuierlicher Spülung, hauptsächlich für Pflanzenschutzmaschinen in der Landwirtschaft, dessen Eingang mit einer Zuleitung, dessen Ausgang mit einer Düsenzuleitung und dessen Innenraum mit einem Behälter verbunden ist.The present invention relates to a filter continuous rinsing, mainly for Plant protection machines in agriculture, whose Input with a supply line, the output with a Nozzle feed and its interior with a container connected is.

Es ist ein Filter mit Spülung, hauptsächlich für Pflanzenschutzmaschinen in der Landwirtschaft, aus der Fachzeitschrift "AGRARTECHNIK" (BRD, Mai 1986) bekannt, dessen Wesen darin liegt, daß sein Eingang mit der Zuleitung, sein Ausgang mit der Düsenzuleitung und sein Innenraum über ein Absperrventil mit einem Tank (Behälter) verbunden ist.It is a filter with flushing, mainly for Plant protection machines in agriculture, from the Trade magazine "AGRARTECHNIK" (FRG, May 1986) known, whose essence is that its entrance with the Inlet, its outlet with the nozzle inlet and its Interior via a shut-off valve with a tank (container) connected is.

Der Nachteil dieser bekannten Lösung liegt darin, daß die Unterbrechung der Spülung durch äußere Einwirkung erfolgt, infolge des subjektiven Charakters der Kapazitätsänderung des Filters unwirksam ist, eine besondere Überwachung notwendig macht und das Filter daher unwirtschaftlich ist.The disadvantage of this known solution is that the Interruption of the flushing takes place due to external influences, due to the subjective nature of the capacity change the filter is ineffective, special monitoring necessary and the filter is therefore uneconomical.

Das Ziel der Erfindung liegt in der Beseitigung obiger Nachteile, d.h. in der Schaffung eines Filters mit kontinuierlicher Spülung, d.h. mit automatischer Reinigungsfähigkeit.The aim of the invention is to eliminate the above Disadvantages, i.e. in creating a filter with continuous rinsing, i.e. with automatic Cleanability.

Die Aufgabe dieser Erfindung besteht in einem Filter, aus dem der Schmutz selbst herausgelangt, ohne daß der Schmutz an unerwünschte Stelle gelangt bzw. ohne daß der Betrieb des Filters dabei zu unterbrechen wäre.The object of this invention consists in a filter which the dirt itself can get out without the dirt gets to an undesired place or without the operation the filter would have to be interrupted.

Die gesetzte Aufgabe wird an dem Filter eingangs genannter Art erfindungsgemäß dadurch gelöst, daß sein Innenraum und der Behälter über ein Druckregulierventil verbunden sind. The task set is mentioned at the beginning of the filter Art solved according to the invention in that its interior and the containers are connected via a pressure regulating valve.  

Zur Steigerung der Wirksamkeit ist die Ausführungsform von Vorteil, bei der der Innenraum über ein Druckregulierventil, das an der dem Eingang gegenüberliegenden Seite angeordnet ist, mit dem Behälter verbunden ist.To increase the effectiveness, the embodiment of Advantage in which the interior has a Pressure regulating valve, which at the the entrance opposite side is arranged with the container connected is.

Die Erfindung soll anhand eines zweckmäßigen Ausführungsbeispieles an Hand der Zeichnung näher dargelegt werden. In der Zeichnung istThe invention is based on an expedient Exemplary embodiment with reference to the drawing be presented. In the drawing is

Fig. 1 ein erfindungsgemäßes Filter schematisch. Fig. 1 shows a filter according to the invention schematically.

Der Eingang 1 des erfindungsgemäßen Filters ist mit der Zuleitung 2 und der Ausgang 3 mit der Düsenzuleitung 4 verbunden.The input 1 of the filter according to the invention is connected to the feed line 2 and the output 3 to the nozzle feed line 4 .

Der Innenraum 5 des erfindungsgemäßen Filters ist durch eine Leitung 6 an einem Behälter (Tank) angeschlossen, der nicht abgebildet wurde.The interior 5 of the filter according to the invention is connected by a line 6 to a container (tank) which has not been shown.

An der Leitung 6 zwischen dem Innenraum 5 und dem Behälter ist ein Druckregulierventil 7 angeordnet.A pressure regulating valve 7 is arranged on the line 6 between the interior 5 and the container.

Die Funktion des erfindungsgemäßen Filters ist im folgenden näher dargelegt.The function of the filter according to the invention is in set out the following.

Die ungefilterte Flüssigkeit, die von der Pumpe durch die Zuleitung 2 gefördert ist, fließt in den Innenraum 5 des erfindungsgemäßen Filters hinein.The unfiltered liquid, which is pumped through the feed line 2 by the pump, flows into the interior 5 of the filter according to the invention.

Von hier aus gelangt ein Teil der Flüssigkeit durch einen Filtereinsatz 9 in die Düsenzuleitung 4, während der andere Teil, der sich aus der Überförderung der Pumpe ergibt, durch ein Druckregulierventil 7, das zweckmäßig an der dem Eingang 1 gegenüberliegenden Seite 8 angeordnet ist, und eine Leitung 6 in den Behälter zurückfließt. From here, part of the liquid passes through a filter insert 9 into the nozzle feed line 4 , while the other part, which results from the over-delivery of the pump, through a pressure regulating valve 7 , which is expediently arranged on the side 8 opposite the inlet 1 , and a line 6 flows back into the container.

Infolge der Rückströmung der Flüssigkeit nimmt sie den Schmutz, der aus der Flüssigkeit herausgefiltert wurde, kontinuierlich mit sich, d.h. es findet eine kontinuierliche Spülung statt.As a result of the backflow of the liquid, it takes the Dirt that has been filtered out of the liquid continuously with itself, i.e. it finds one continuous rinsing instead.

Die Vorteile des erfindungsgemäßen Filters bestehen darin, daß es ohne äußere, auf subjektiver Beurteilung beruhende Einwirkung und Betriebsunterbrechung eine stetige Selbstreinigung gewährt, daß weiter das Druckregulierventil, das im übrigen für das Flüssigkeitssystem sowieso notwendig ist, durch das erfindungsgemäße Filter mit einer Doppelfunktion versehen wird, wodurch seine Wirtschaftlichkeit gesteigert wird, und daß zuletzt es keiner zusätzlichen Ausrüstungen bedarf, es also wirtschaftlich ist.The advantages of the filter according to the invention are that it is without external, based on subjective judgment Impact and business interruption a steady Self-cleaning grants that further Pressure regulating valve, the rest for the Fluid system is necessary anyway through that filter according to the invention provided with a double function which increases its profitability, and that ultimately there is no additional equipment needs, so it is economical.
