<p>PCT No. PCT/SE80/00260 Sec. 371 Date Jul. 17, 1981 Sec. 102(e) Date Jul. 17, 1981 PCT Filed Oct. 28, 1980 PCT Pub. No. WO81/01372 PCT Pub. Date May 28, 1981.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.</p> |
