Detailed Description
The present invention will be further illustrated with reference to the accompanying drawings and specific embodiments, which are to be understood as merely illustrative of the invention and not as limiting the scope of the invention. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.
As shown in the figure, the sand blasting, sand returning and dust removing integrated non-contact array spray gun comprises a sand returning cavity 3, a sand returning pipe 6, straight nozzles 9, an air inlet pipe 5, an air curtain cavity 2 and a hanging ring 7, wherein the air curtain cavity 2 surrounds the outer side of the sand returning cavity 3, a guide plate 1 is arranged below the air curtain cavity 2, the air inlet pipe 5 is communicated above the air curtain cavity 2, the air inlet pipe 5 is connected with an air source, the straight nozzles 9 are arranged in the sand returning cavity 3, the rear ends of the straight nozzles 9 are connected with a sand pipe connecting piece 8, the sand returning pipe 6 and auxiliary pipes 10 are arranged among the straight nozzles 9 (each sand returning pipe 6 is divided into 1-3 auxiliary pipes 10, and the way of sand suction is increased), and the rear end of the sand returning pipe 6 is connected with a vacuum sand suction machine.
The sand blasting, sand returning and dust removing integrated non-contact array spray gun can be an arc surface operation device, an air inlet pipe 5 is ventilated to open an air curtain during operation, as shown in figure 4, air flow is sprayed onto a steel plate to form a closed air curtain, the closed air curtain isolates an operation surface from a non-operation surface, and the spray gun and an ultra-large plane steel plate 11 to be subjected to sand blasting are not in contact due to the fact that the air flow is sprayed.
