Abstract
A slurry tank autocleaner for cleaning an empty slurry tank. A first pipe is inserted in the interior of the slurry tank, where the first pipe has an open end located inside the slurry tank. A first nozzle is disposed on the open end of the first pipe. A cover is used to cover the slurry tank, where the cover has a plurality of second nozzles targeting the slurry tank. A second pipe is connected to the second nozzles. A controller is used to control chemical, pure water or dry gas to spurt from the first nozzle and the second nozzles through the first pipe and the second pipe. Thus, the slurry tank can be automatically cleaned.
