When the sand and the impurities enter, they fall on the filter screen, the filter screen filters the large sand and then falls to the bottom of the recovery tank 22. Then the dust and the small impurities enter the fixed box 28, then enter the filter pipe 24, then enter the filter cartridge 25, and then are discharged after being filtered by the filter core 202 in the filter cartridge 25, so as to ensure that the tail gas discharge does not pollute the air. When the sand in the recovery tank 22 is recovered to the position, the one-way valve 201 is manually opened, the sand falls into the sand supply tank, and then the sand supply operation is repeatedly performed. The robot moves on the surface of the ship and continuously cleans, so as to clean the rust and impurities on the surface of the ship. Compared with the traditional manual operation, the intelligent and automatic cleaning is realized, which is convenient for the staff to operate.
