[0002] The steel sand recycling circulating device for ship shot blasting derusting is a device for recycling and recycling the steel sand used in the process of ship shot blasting derusting. During ship shot blasting derusting, the shot blasting machine projects steel sand at high speed to the surface of the ship to remove rust and impurities such as old paint.

[0060] In this embodiment, during use, the operator adds the recovered steel shot to the recovery box 1 through the feed hopper 2. At this time, the steel shot is initially screened by the cooperation of the sieve plate 3 and the sieve ring 4, thus separating large impurities from the steel shot. During the initial screening process, the operator controls the first motor 12 to operate, which drives the stirring column 11 to rotate. This stirs the steel shot through the scraper and stirring rod, improving the efficiency of the initial screening. After the initial screening is completed, the steel shot and small impurities fall into the sieve cylinder 6. Then, the operator controls the second motor 15 and the third motor 23 to operate. The second motor 15 drives the first gear 14 to rotate, and the meshing of the first gear 14 with the first gear ring 13 drives the drive ring 5 and the sieve cylinder 6 to rotate, facilitating the separation of steel shot and small impurities under centrifugal force. The third motor 23 drives the support column 16 to rotate. This allows the scraper 20 to move around the support column 16. Simultaneously, the rotation of the support column 16 drives the first bevel gear 25 to move around the second bevel gear 26. The meshing of the first bevel gear 25 and the second bevel gear 26 drives the reciprocating screw 24 to rotate. Furthermore, the cooperation between the reciprocating screw 24 and the screw nut drives the scraper 20 and the support block 18 to move within the support groove. This cleans impurities adhering to the surface of the screen cylinder 6 when the scraper 20 contacts it. Simultaneously, the movement of the scraper 20 agitates the steel sand, improving the screening efficiency of the screen cylinder 6. After screening, the opening and closing of the first control valve and the operation of the screw conveyor 10 discharge large impurities remaining on the screen plate 3 into the recovery box 1. Small impurities are discharged through the first discharge port 8, and steel sand is discharged through the second discharge port 9, facilitating the recovery and recycling of the steel sand.
