ABSTRACT:
A belt filter device for the cleaning of contaminated liquids has an upper dirt chamber which receives the contaminated liquid. Underneath this dirt chamber, a clean chamber is arranged. Between the dirt chamber and the clean chamber, a filter bottom is provided which has a passage opening for the liquid and on which a revolving filter belt is arranged so that it can be moved along automatically as a function of the amount of contaminations deposited on it. Outside the dirt chamber, a cleaning device is arranged which removes the contaminations situated on the filter belt. The cleaning device has at least one spray head which is arranged on the rear of the filter fabric and above the level of the contaminated liquid so that the dirty cleaning liquid is supplied directly to the contaminated liquid.
