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 type bent nozzle spray gun adopts a non-contact type operation mode and comprises an elbow connecting piece 1, an air curtain cavity 2, a sand-returning cavity 3, a sand pipe connecting piece 4, an air curtain air inlet pipe 5, an elbow nozzle 6, an air curtain guide cover 7, a straight nozzle 8 and a sand-returning pipe 9, the elbow connecting piece 1 is arranged at the front end of the sand return cavity 3, the air curtain cavity 2 is arranged at the outer side of the elbow connecting piece 1, the front end of the air curtain cavity 2 is provided with an air curtain guide cover 7, the rear end of the air curtain cavity 2 is connected with an air curtain air inlet pipe 5, the air curtain air inlet pipe 5 is connected with an air source, the straight nozzle 8 is arranged in the sand return cavity 3, the front end of the straight nozzle 8 is connected with the elbow nozzle 6, the elbow nozzle 6 is arranged in the elbow connecting piece 1, the rear end of the straight nozzle 8 is connected with the sand pipe connecting piece 4, the sand return pipe 9 is arranged on the side surface of the sand return cavity 3, and the rear end of the sand return pipe 9 is connected with a vacuum sand sucker.
When the work is carried out, a workpiece to be sandblasted is placed at a proper position at the front end of a spray gun, the position of the elbow nozzle 6 away from the workpiece is calculated, iron sand is sprayed out from the elbow nozzle 6 along a straight nozzle 8, an air curtain is opened by ventilating an air curtain air inlet pipe 5, as shown in figure 3, the iron sand sprayed out from the elbow nozzle 6 splashes on the workpiece 12, whirling air flow is mixed into the air curtain when the iron sand collides with the air curtain (the air pressure of the air curtain sprayed out is enough, the popped iron sand cannot break the air curtain and is finally mixed into the whirling air flow), a vacuum sand sucker is started, negative pressure suction is generated in a sand return pipe 9, the iron sand is sucked into a sand return cavity 3 and then sucked back into the vacuum sand sucker (dust is also sucked back), the air curtain is also reflected inwards and outwards after being sprayed onto a workbench to isolate a working surface from a non-working surface, the iron sand and the dust in the air curtain cannot overflow, and the dust cannot enter outside, so that the sand flow and the, the working environment is purified.
