The invention concretely relates to a high efficiency maintenance-free storage tank cabin top dust collection device on an aluminum oxide concentrated phase and dilute phase transportation tail end aluminum oxide storage tank in the aluminum electrolysis production enterprises. The dust collection device comprises an air source device and a dust collection box. The upper part of the dust collection box is provided with an air outlet and the lower part thereof is matched with an exhaust port on the top of the aluminum oxide storage tank cabin in structure. The air source device transfers air to a nozzle in the dust collection box through a pipeline thereof. The box body of the dust collection box is divided into an upper cavity and a lower cavity through a clapboard. The pipeline provided with the nozzle and transferring the air is located at the upper cavity. Filter drums are located at the lower cavity and are suspended on the clapboard. The nozzles correspond to a plurality of filter drums one to one. The i
