Abstract
A sludge robot for the removal of sludge from sedimentation tanks having planar bottoms comprises a rising tube (3) and two tube arms (5, 8) which are interconnected by two motor couplings (1, 2), by means of which the tube arms can be steered along a predetermined track over the whole bottom of the tank and suck the whole bottom free from sludge through a suction opening. Steering of the motor couplings is carried out by means of a micro dator (18) programmed for the relevant tank size. The sludge robot operates close to the tank bottom all the time and permits other applications in the upper portion of the tank. Starting time and cycle time for the sludge robot are adjustable.
Claims9
A sludge robot for removal of sludge and sedimental particles from a sedimentation tank or the like and comprising a rising tube and at least two tube arms of which one is rotatably connected to the rising tube at its one end and the second tube arm is rotatably connected to the other end of said one tube arm and at its one end and has a suction inlet at its other, free end, characterized by the provision of motor couplings, which interconnect said one tube arm with the rising tube on one hand and the second tube arm on the other hand, for rotating the two tube arms which are provided in the lower portion of the tank, adjacent to its bottom according to a predetermined program, and control means for steering the motor couplings in such a way that the suction inlet moves in a predetermined movement pattern over substantially the whole bottom of the tank.
