The movable air suction device comprises a collecting box, a containing frame is connected to the outer wall of the bottom of one side of the collecting box, an electric arc wire spraying machine is placed above the containing frame, and a spraying gun storage assembly is arranged on the outer wall of the top end of the collecting box; a water-cooling precipitation assembly is arranged in the collecting box and the containing frame, and an air suction discharging assembly is arranged on the inner wall of the bottom of the collecting box; and a spraying gun is arranged above the collecting box, and the end of the spraying gun is connected with a connecting wire. The air suction device can carry an electric arc wire spraying machine to be used, the air suction device and the electric arc wire spraying machine can be transferred and moved conveniently, dust generated in the electric arc wire spraying process can be collected, a user can achieve suction at a designated position on a workpiece through a lower pipe rod and a dust suction head structure in cooperation with the air suction discharging assembly, the suction force is high, and special treatment on the workpiece is facilitated.

Description

technical field [0001] The invention relates to the technical field of arc wire spraying equipment, in particular to a movable air suction device of an arc wire spraying device. Background technique [0002] Arc spraying is a technology that uses an electric arc that burns between two continuously fed metal wires to melt metal, atomizes the molten metal with high-speed airflow, and accelerates the atomized metal particles so that they are sprayed to the workpiece to form a coating. ; Arc spraying is the most commonly used thermal spraying method in practical application projects such as steel structure corrosion resistance, wear resistance and mechanical parts maintenance; arc spraying systems are generally composed of special power supplies for spraying, control devices, arc spray guns, and wire feeders. and compressed air supply system.

AI Technical Summary

Problems solved by technology

[0003] In the process of arc wire spraying, a large amount of metal dust will be generated, so that the suction device is often used to collect dust during the spraying process, but the structure of the dust suction device on the market is relatively simple, which is not conducive to the adaptation of the arc wire spraying machine. The air suction device cannot move with the spraying machine, and the air suction device does not have the ability to retract the spray gun. The traditional spray gun has a long electrical wire, which is messy during use. The traditional dust suction device cannot absorb the dust. Precipitation treatment of dust makes the dust easy to disperse, which affects the dust collection effect, and the dust collected by the suction device is not conducive to later discharge; therefore, it is very meaningful to design a movable suction device for the arc wire spraying device
