[0023] The utility model provides a vacuum welding box residual material collection, filtration, smoke and dust exhaust purification device, such as Figure 1 As shown, it includes: a flatbed car 1, on which a dust hood 2, a first curved pipe 3 and an axial flow fan 5 are arranged, the dust hood 2 is connected to one end of the first curved pipe 3, a filter screen 4 is arranged in the first curved pipe 3, the other end of the first curved pipe 3 is connected to the air inlet of the axial flow fan 5, the air outlet of the axial flow fan 5 is connected to one end of the air distribution pipe 6, a second curved pipe 8 is fixed above the outdoor collection barrel 7, and the other end of the air distribution pipe 6 is connected to the end of the second curved pipe 8 away from the outdoor collection barrel 7. The second curved pipe 8 passes through the wall and is fixedly connected to the wall. The air distribution pipe 6 adopts a temperature-resistant air distribution pipe, which is a flexible air distribution pipe woven from special fibers, which can slow down the airflow and make the airflow uniform and soft.

[0024] The working principle and beneficial technical effects of the above technical solution are as follows: the dust hood 2 is connected to the exhaust port of the vacuum welding box, and the axial flow fan 5 is started to generate negative pressure. The smoke generated by the welding box during welding is sucked in through the dust hood 2, filtered by the filter 4, and large dust particles and metal particles are blocked by the filter. After the airflow is decelerated by the air distribution pipe 6, it enters the second bend 8 and is discharged outside the wall. A large amount of dust and metal particles in the smoke can be removed by filtering through the filter. After the airflow is decelerated by the air distribution pipe 6 and enters the second bend 8, the remaining dust and metal particles fall into the collection bucket 7 under the action of gravity after the airflow is decelerated. The gas is discharged outside the working environment, reducing the harm to the health of the staff. The air distribution pipe 6 can be easily bent and stretched, so that the device can be moved to different vacuum welding boxes through the flatbed car 1 to purify the smoke, and it is easy to move and carry.
