Description

Vynález se týká filtru s nepřetržitým proplachováním, zejména pro zemědělské stroje na ochranu rostlin, jehož vstup je spojen s přívodem, výstup s tryskami a vnitřní prostor s nádrží pro kapalinu.BACKGROUND OF THE INVENTION The invention relates to a continuous flushing filter, in particular for agricultural plant protection machines, the inlet of which is connected to an inlet, an outlet with nozzles and an interior with a liquid tank.

. Nevýhoda tohoto známého řešení spočívá v tom, že proplachování filtru je vlivem vnějších okolností přetržité, změna výkonu je v důsledku nedokonalé konstrukce nesnadná, filtr vyžaduje neustálý dohled a není proto z uvedených důvodů hospodárný.. The disadvantage of this known solution is that the flushing of the filter is interrupted due to external circumstances, the power change is difficult due to the imperfect construction, the filter requires constant supervision and is therefore not economical for the reasons stated.

Okolem vynálezu je odstranit uvedené nevýhody a vyvinout filtr s nepřetržitým proplachováním, to jest, se schopností automatického čištění, aniž by nečistota vnikla na nežádoucí místo, popřípadě, aniž by bylo třeba provoz filtru přerušovat.It is an object of the present invention to overcome these disadvantages and to develop a continuous flush filter, i.e., with an automatic cleaning capability, without dirt entering an undesired location, or without interrupting filter operation.

Podstata vynálezu u filtru shora uvedeného typu spočívá v tom, že vnitřní prostor filtru a nádrž pro kapalinu jsou spojeny přes tlakový regulační ventil. Tlakový regulační ventil je uspořádán na protilehlé straně vzhledem ke vstupu kapaliny.The principle of the invention in the case of a filter of the above type consists in that the inner space of the filter and the liquid tank are connected via a pressure control valve. The pressure control valve is arranged on the opposite side to the liquid inlet.

Výhody filtru podle vynálezu spočívají', v tom, že bez vnějších nahodilých okolností je stroj samočinně nepřetržitě proplachován, protože tlakový regulační ventil, jehož je u zemědělského stroje pro ochranu rostlin stejně třeba, má u filtru podle vynálezu dvojí funkci, takže není třeba nijakého dalšího přídavného zařízení, čímž se zvyšuje produktivita filtru.The advantages of the filter according to the invention are that, without external accidental circumstances, the machine is automatically flushed continuously, since the pressure control valve, which is equally needed in an agricultural plant protection machine, has a dual function in the filter according to the invention, additional equipment, thereby increasing filter productivity.

Vynález je blíže popsán na příkladu jednoho provedení znázorněného na výkresu, jehož obr. 1 představuje schéma filtru podle vynálezu.BRIEF DESCRIPTION OF THE DRAWINGS The invention is described in more detail by way of example of one embodiment shown in the drawing, of which Fig. 1 is a diagram of a filter according to the invention.

Vstup JL filtru podle vynálezu je spojen s přívodním potrubím 2 a výstup 3_ s přívodem 4_ kapaliny do trysek. Vnitřní prostor 2 filtru podle vynálezu je spojen potrubím _6 s nádrží pro kapalinu, která není znázorněna. Do potrubí 6 je mezi vnitřním prostorem 2 a nádrží zapojen tlakový regulační ventil 2·The filter inlet 11 of the invention is connected to the inlet pipe 2 and the outlet 3 to the liquid inlet 4 of the nozzles. The inner space 2 of the filter according to the invention is connected via a line 6 to a liquid tank (not shown). A pressure control valve 2 is connected to the pipeline 6 between the inner space 2 and the tank.

Filtr podle vynálezu pracuje takto. Nefiltrovaná kapalina dopravovaná potrubím 2 teče do vnitřního prostoru 2 filtru.The filter according to the invention operates as follows. The unfiltered liquid conveyed through line 2 flows into the interior of the filter 2.

Její část protéká filtrační vložkou 2 ěo přívodu 4 kapaliny do trysek, kdežto druhá část, vznikající přeplněním vnitřního prostoru 2 kapalinou dodanou čerpadlem, protéká tlakovým regulačním ventilem ]_, uspořádaným na straně 2 protilehlé proti vstupu 1_ a vrací, potrubím 2 čo nádrže pro kapalinu.A part thereof flows through the filter insert 2 to the liquid supply 4 to the nozzles, while the other part, resulting from overfilling of the interior space 2 with the liquid supplied by the pump, flows through the pressure control valve 1 arranged on the side 2 opposite .

Část kapaliny protékající tlakovým regulačním ventilem 2 unáší nepřetržitě nečistotu zadrženou filtrační vložkou 2λ čímž je vnitřní·prostor 2 filtru podle vynálezu nepřetržitě proplachován.A portion of the fluid flowing through the pressure control valve 2 continuously carries the dirt retained by the filter element 2λ, whereby the interior space 2 of the filter according to the invention is continuously flushed.
