- German patent document DE 101 54 134 A1 discloses a granulating device whose process fluid in the form of a liquid coolant is circulated through a particle filter in order to filter out and separate impurities from the process liquid which have been introduced into the process liquid during pelleting or granulation.
- a filter belt which circulates endlessly in the manner of a conveyor belt is provided as the particle filter onto which the contaminated process fluid to be filtered is fed, so that the fluid passes through the upper run and lower run of the filter belt and particles are collected on the filter belt.
- the impurities collected on the belt are transported away. continuously removed from the belt with a scraper in a discharge area.
- filter belts for filtering contaminated liquids are particularly advantageous in industrial plants, in which process fluid is circulated, since the system does not need to be stopped in order to clean the filter.
- the solids accumulating in the feed area on the filter belt are led out of the feed area by the movement of the filter belt, so that they can be removed from the filter belt in a discharge area which lies outside of said feed area.
- a fresh or cleaned filter belt section is driven into the feed area by the movement of the filter belt, so that there always a fresh, functional filter belt section performs the filtration.
- the present invention has the object to provide an improved filtration device of the type mentioned, which avoids the disadvantages of the prior art and further develops the latter in an advantageous manner.

- the band cleaner has at least one brush which can be driven in rotation, to which a brush cleaner with a scraper, which is arranged in the orbit of the bristles of the rotating brush, is assigned.
- the rotating brush efficiently removes the adsorbed solids from the filter belt, while the scraper of the brush cleaner at the same time ensures that the dissolved solids do not attach to the brush and enforce this. Especially with sticky contaminants of the liquid to be filtered, the continuous self-cleaning of the brush is very helpful in order to ensure a permanently efficient, continuous separation of the solids.
- the scraper used for self-cleaning the rotating drivable brush can basically be designed differently.

- the bearing of the scraper may also have a mobility in that the scraper can be arranged in different circumferential segments, so that the stripping operation can be carried out at different locations, for example to avoid spewing the stripped solids back onto the filter belt.
- the scraper for the brush can be arranged on the side opposite the filter belt side of the brush. If the point of engagement of the brush on the filter belt defines the angular position 0 °, the scraper can be arranged for example in an angular segment between 90 ° and 270 °, so to speak in the second and third quadrant of the circulating movement of the brush.

- a feedback control of the brush speed can take place in that the filter belt section cleaned by the brush is observed and detected for its cleanliness, for example by optical sensors or a determination of the air and / or liquid permeability of the belt. The brush speed is then controlled so that there is a maximum cleanliness of the filter belt downstream of the brush. Further operating parameters can be used in this speed control of the cleaning brush.
