[0028] Working principle: When working, first place the steel pipe above the roller 4 so that the roller 4 is located inside the shot blasting box 6. When the shot blaster 7 is turned on, the shot blasting port of the shot blaster 7 sprays steel shots downward, and the steel shots produce impact force on the surface of the steel pipe, thereby polishing and cleaning the surface. When the roller 4 rotates, it drives the steel pipe forward, and the steel pipe rotating frame 9 is used to drive the steel pipe to rotate, thereby completely cleaning the outer wall of the steel pipe;

[0029] After the steel shot is ejected, the steel shot falls into the blanking cavity 3, and the inner bottom wall of the blanking cavity 3 is provided with an inclined surface 1002, so that the steel shot rolls along the inclined surface 1002 toward the top tube 1001, and enters the rotating cylinder 1005 from the top tube 1001 and the material tube 1006, and at the same time, the debris cleaned off the surface of the steel tube also enters the rotating cylinder 1005 along with the steel shot;

[0030] When one steel pipe is cleaned, the steel pipe is replaced, and at the same time, the electromagnet 1015 is energized to generate attraction to the magnetic block 1014, pulling the movable baffle 1009 to move upward into the material pipe 1006, thereby closing the material pipe 1006 to prevent the steel shot from falling out, and turning on the motor 1008 to rotate the rotating cylinder 1005. Under the action of friction, the debris adhered to the surface of the steel shot is separated from the steel shot, and at the same time, under the action of centrifugal force, the debris is thrown outward from the filter hole 1007 into the processing box 1003. At this time, the receiving box 1104 is located in the side box 1101, and the debris slides down along the inner wall of the processing box 1003 and is discharged from the bottom tube 1004;

[0031] When the debris is completely discharged, the motor 1008 adjusts the rotating cylinder 1005 to a state where the material tube 1006 is facing downward and corresponds to the bottom tube 1004, controls the cylinder 1106 to push the receiving box 1104 into the bottom tube 1004, and controls the electromagnet 1015 to be powered off. At this time, the movable baffle 1009 enters the rotating cylinder 1005 under the elastic force of the spring 1013, so that the material tube 1006 is opened. At this time, the steel shot in the rotating cylinder 1005 is discharged downward from the material tube 1006 into the receiving box 1104. After the steel shot is completely discharged, the output end of the cylinder 1106 retracts to pull the receiving box 1104 back into the side box 1101;

[0032] When the receiving box 1104 is inside the bottom tube 1004, the discharge trough 1105 on the receiving box 1104 is located above the fixed baffle 1103, and the fixed baffle 1103 closes the discharge trough 1105, so that the steel balls will not be discharged from the bottom tube 1004. When the receiving box 1104 enters the side box 1101, the discharge trough 1105 is opened. At this time, the steel balls in the receiving box 1104 are discharged from the discharge trough 1105 into the side box 1101, and then the hoist 8 is opened to lift the steel balls collected in the side box 1101 to the shot blasting box 6 for recycling.
