7. A blasting method for treating a high-hardness corrosion-resistant surface of a metal pot body according to any one of claims 1 to 6, comprising the steps of:
s1, filling a sufficient amount of fine sand into the fixed box (1), introducing high-pressure gas into the gas transmission ring (2) through the transmission belt (14), enabling the high-pressure gas to enter the sealing ring (3) to impact the rotating blades (25), enabling a part of the high-pressure gas to flow from the shaft pipe to the gas guide plate (4), and finally uniformly spraying the high-pressure gas upwards from the feeding pipe (7), ensuring that the gas amount entering from the transmission belt (14) is larger than the gas amount sprayed from the feeding pipe (7), gradually pressurizing the other part of the gas in the sealing ring (3) and positioned between the two rotating blades (25), and pushing the rotating blades (25) to rotate along with the increase of the pressure;
s2, the rotating blades (25) rotate, and the supporting ring (5) and the rotating shaft (16) are respectively driven by the sealing ring (3) and the shaft tube air guide plate (4). The rotating shaft (16) drives the helical blade (18) to rotate, and the helical blade (18) gradually inputs the fine sand in the fixed box (1) into the conveying box (17) so that the fine sand gradually spreads into the feeding pipe (7) and gradually reaches the top end of the air nozzle (8);
s3, adsorbing the metal pot body by using a sucking disc, driving a gear shaft (12) to advance in an outer box (9) through a transmission belt (14) and a pulling ring (15), driving the metal pot body to rotate through the gear shaft (12) due to the matching of the gear shaft (12) and a rack, and finally rotating while revolving above a feeding pipe (7);
s4, after the fine sand gradually rises to the top end of the jet head (8), covering a layer of fine sand on the jet port of the jet head (8) to meet the gas jetted vertically upwards, wherein the gas impacts the fine sand and is jetted vertically upwards from the feed pipe (7) at a high speed to impact the surface of the metal pot body;
s5, after the metal pot body rotates 180 degrees above the feeding pipe (7), the sand blasting process is completed, the pot body is replaced along with the fact that the transmission belt (14) reaches the opening of the outer box (9), sand blasting is conducted on the next piece, and the sprayed fine sand loses kinetic energy after impacting the metal pot body, descends under the action of gravity and limits the outer box (9), and falls into the fixing box (1) again.
