The part with higher sand content in the sand-water mixture is introduced into the high-pressure inlet of the next sand-water separator, and the sand content in the sand-water mixture flowing out from the outlet of the lower layer of the next sand-water separator is further increased, and then introduced into the sandblasting nozzle for sandblasting work. In this way, the working efficiency of the sandblasting machine is significantly improved, and since the sand content in the sprayed sand-water mixture is significantly increased, the cleaning effect on the surface of the workpiece is significantly improved. The invention also improves the structure of the sand pump, adjusts the impeller mechanism of the sand blasting machine, and makes the central area of the back of the impeller also form a negative pressure, so that the gap between the transmission shaft and the sand shell of the sand pump is in the low-pressure area. The gap between them is in the state of negative pressure suction, and sand and water will not be ejected, which significantly improves the overall service life of the sand pump. In addition, the invention also improves the spout part of the nozzle, so that the inner cavity of the spout adopts a specific hyperbolic structure, which can effectively use the energy of compressed air to accelerate the sand, without increasing the power of compressed air , which can effectively improve the acceleration efficiency, and play a role in saving energy and improving performance.
