Description

Technical Field

[0001] The utility model relates to the technical field of welding slag collection, in particular to a device for collecting falling welding slag of outer annular seam welding. Background Art

[0002] Welding technology, also known as connection engineering, is an important material processing technology. The definition of welding is as follows: the materials of the workpieces to be welded (same or different) are heated or pressurized or both, and with or without filler materials, so that the materials of the workpieces can achieve atomic bonding to form a permanent connection. Welding will produce welding slag, which requires a welding slag collection device. The general welding slag collection device is not convenient to adjust according to the position of the welding table, which affects the collection of welding slag.

[0003] In the prior art, a Chinese patent document with patent number CN214516668U proposes a device for collecting welding slag of construction steel bars, including a device box, a dust collection and reduction mechanism arranged inside the device box, the dust collection and reduction mechanism comprising a connecting pipe, a collecting hood, cooling water and an ultrasonic oscillator, the top of the device box is connected with a connecting pipe, and the top of the connecting pipe is connected with a collecting hood. Although the utility model can oscillate cooling water to form a large amount of water mist through the cooling water and ultrasonic oscillator in the device box, and use the water mist to reduce dust on external welding dust, in actual use, welding slag generated by the existing outer ring seam during welding splashes on the collecting hood. Since the welding slag itself has a small weight and a slow flow rate, the collection efficiency is low. In addition, the welding slag falls vertically into the collecting box through the collecting hood. Because the collecting box is fixed on the bottom surface of the collecting device, it is not convenient for the staff to clean the welding slag in the inner cavity of the collecting box. Therefore, we disclose a device for collecting the falling welding slag of the outer ring seam welding to meet the actual demand that the welding welding slag at the bottom of the inner cavity of the collecting box is difficult to clean.
