Abstract

The sweeper has a filter system integrated into a rough sweeping leveling container, where the system has a number of filter units (5) for cleaning vacuum air flow from particulate matter. The filter units are cleaned with compressed air from a compressed air tank in a temporary or differential pressure controlled manner by a clean gas-side quick-action valve (4) attached in a clean-gas chamber (2).

Description

Bei bekannten Kehrmaschinen mit Saugvorrichtung wird Staub und Schmutz durch einen Ventilator (1) in den Grobkehrichtbehälter (6) gesaugt. Grobe Partikel bleiben in dem Grobkehrichtbehälter liegen und die Saugluft entweicht mit dem enthaltenen Feinstaub durch den Ventilatorausgang ins Freie.In known sweepers with suction dust and dirt by a fan ( 1 ) into the waste container ( 6 ) sucked. Coarse particles remain in the coarse waste container and the suction air escapes with the contained fine dust through the fan outlet to the outside.

Eine bekannte Kehrmaschine mit den vorgenannten Merkmalen zum Reinigen von Strassen, Plätzen usw. unterliegt dem Nachteil, dass der Abluftstrom mangels geeigneter Filtration erheblich mit Feinstaub verunreinigt ist.A known sweeper with the aforementioned features for cleaning of streets, squares etc. is subject to the disadvantage that the exhaust air flow for lack of suitable Filtration is significantly contaminated with particulate matter.

Die Aufgabe der Erfindung ist es eine Kehrmaschine mit Filtersystem zu schaffen, das den Feinstaub im Abluftstrom zurückhält und mit einer Abreinigungsvorrichtung ausgestattet ist, das die Filterelemente selbsttätig während dem Betrieb reinigt, um einen Dauerbetrieb zu ermöglichen.The The object of the invention is a sweeper with filter system to create that retains the fine dust in the exhaust air flow and with a cleaning device is equipped, which the filter elements automatic while cleans the operation to allow continuous operation.

Die Erfindung betrifft eine Kehrmaschine mit einem in den Grobkehrichtbehälter (6) eingebauten selbstreinigenden Filtersystem zur Reinigung des vom Ventilator (1) erzeugten Saugluftstroms von Feinstaub.The invention relates to a sweeper with a in the large waste container ( 6 ) built-in self-cleaning filter system for cleaning the fan ( 1 ) produced suction air flow of fine dust.

Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass das Filtersystem, welches aus mehreren Filterelementen (5) besteht, in den Grobkehrichtbehälter (6) einer Kehrmaschine eingebaut und reingasseitig über einen Reingasraum (2) mit dem Ventilator (1) verbunden wird.This object is achieved according to the invention in that the filter system, which consists of several filter elements ( 5 ) into the waste container ( 6 ) built on a sweeper and the clean gas side via a clean gas room ( 2 ) with the fan ( 1 ) is connected.

Reingasseitig ist im Reingasraum (2) an jedem Filterelement jeweils 1 Schnellschlussventil (4) angebracht Die Schnellschlussventile sind mit dem Presslufttank (3) welcher mit Pressluft beaufschlagt ist und einer elektrischen Filtersteuerung verbunden.The clean gas side is in the clean gas room ( 2 ) on each filter element 1 quick-closing valve ( 4 ) The quick-acting valves are connected to the compressed air tank ( 3 ) which is supplied with compressed air and connected to an electric filter control.

Die in den Grobkehrrichtbehälter eingesaugte staubhaltige Luft beruhigt sich und grobe Staubpartikel sinken ab. Der noch im Rohgas enthaltene Feinstaub wird mit der Luft zu den Filterelementen transportiert und wird an deren Oberfläche zurückgehalten.The in the large sweep container sucked in dusty air calms down and coarse dust particles fall off. The still contained in the raw gas particulate matter is with the Air transported to the filter elements and is retained on the surface.

Die reine Luft wird durch die Filterelemente in den Reingasraum gesaugt und durch den Ventilator ins Freie geleitet.The clean air is sucked through the filter elements into the clean gas room and led by the fan to the outside.

Mit zunehmender Staubmenge bildet sich ein Staubkuchen an der Oberfläche der Filterelemente und der Filterwiderstand steigt.With Increasing amount of dust forms a dust cake on the surface of the Filter elements and the filter resistance increases.

Bei zeit- oder differenzdruckgesteuerter Aktivierung des Schnellschlussventils (4) wird kurzzeitig Pressluft aus dem Presslufttank (3) in das erste Filterelement (5) geblasen und dadurch der an dem Filter anhaftende Staubkuchen abgesprengt.With time- or differential-pressure-controlled activation of the quick-closing valve ( 4 ) is compressed air from the compressed air tank ( 3 ) in the first filter element ( 5 ) and thereby blown off the dust cake adhering to the filter.

Beim nächsten Abreinigungsvorgang wird das nächste Filterelement abgereinigt usw.At the next Cleaning process will be the next Filter element cleaned, etc.

Der Feinstaub fällt nach unten in den Grobkehrichtbehälter (6).The fine dust falls down into the waste container ( 6 ).

Somit bleiben der Filterwiderstand und die Saugluftmenge bei hohen Filterstandzeiten nahezu konstant. Die Abluft ist frei von Staub.Consequently the filter resistance and the amount of suction air remain at high filter service life almost constant. The exhaust air is free of dust.

Durch den Einsatz des Filtersystems in Kehrmaschinen mit Saugvorrichtung wird die Staubmenge im Abluftstrom zuverlässig reduziert.By the use of the filter system in sweepers with suction device the amount of dust in the exhaust air flow is reliably reduced.
