Storage tank cleaning machine

摘要

The storage tank cleaning machine is a mobile unit mounted on a trailer for towing by a suitable vehicle. The machine is positioned adjacent the access opening of the tank, e.g., a water tank, cistern, or other storage tank, and a support on the bed of the machine is raised to vertical over the opening. A multiple segment articulating arm extends from the support and is lowered through the opening to access the interior of the tank. A motorized rotary brush extends from the distal end of the arm. Distance sensors adjacent the brush detect the interior surfaces of the tank for accurately positioning the brush. An electronic control system is provided. A tank for water and/or other cleaning fluid and a disinfectant tank are also provided. Fluids used during the cleaning operation are suctioned back to the machine, where the fluids are cleaned and recycled.
