A device for mechanical cleaning a bottom of a radial precipitation tank comprises an above-water part in the form of a carrying element equipped with a drive and based on a pivotal support in the center of the radial precipitation tank, and an underwater part connected to the above-water part, comprising at least one accumulating element equipped with a set of raking elements, and a means for removing sludge from the tank. The accumulating element is designed as a hollow chamber, which internal cavity is limited from below by the tank bottom, on top – by a cover and on the perimeter at least partially it is limited by raking the elements that are adjustably mounted on the cover. The chamber is made with possibility of connection to a device for removing the collected sludge. |
