Embodiment Construction

[0012] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0013] See figure 1 , figure 2 , the present invention includes providing a negative pressure suction hopper A for flux recovery and a storage hopper C for storing flux, a suction fan 14 is installed in the suction hopper A, and a magnetic separation device is installed between the suction hopper A and the storage hopper C. Separation hopper B, the magnetic separation hopper B is respectively connected to the storage hopper C and the air suction port of the suction hopper A, the suction hopper A generates a negative pressure in the magnetic separation hopper B, and the magnetic separation hopper B is connected Flux recovery pipelines 6 and 7 are flux recovery suction nozzles. The suction hopper A, the magnetic separation hopper B and the storage hopper C are integrated, so that the floor area is very small and the cost can be reduced.

Abstract

The invention provides a submerged arc-welding flux recovering device, comprising a wind suction hopper which provides negative pressure for the flux recovery and a storage material hopper which is used for storing flux; the wind suction hopper is internally provided with a wind sucker; the submerged arc-welding flux recovering device is characterized in that a magnetic-selection separation material hopper is arranged between the wind suction hopper and the storage material hopper; the magnetic-selection separation material hopper is respectively communicated with the storage material hopper and the wind suction mouth of the wind suction hopper; the wind suction hopper, the magnetic-selection separation material hopper and the storage material hopper are integrated into a whole; the magnetic-selection separation material hopper is connected with a flux recovery pipeline; the storage material hopper is provided with a heating device; the flux recovered by the submerged arc-welding flux recovering device contains no iron chippings or vapor; when the recovered flux is re-used for welding, the gained surface of the submerged arc-welding seam is smooth and level and generates no air bubbles, and quality defects existing when the submerged arc-welding flux recovering device is carried out by the recovered flux in the prior art can be effectively solved; the wind suction hopper, the magnetic-selection separation material hopper and the storage material hopper are integrated into a whole, thus occupying few areas, thereby reducing the manufacture cost and being small and practical.

Description

technical field [0001] The invention relates to welding equipment, in particular to a flux recovery device on the welding equipment. Background technique [0002] Submerged arc welding has been widely used. Flux is an indispensable welding auxiliary material for submerged arc welding. The flux that has not melted during the welding process should be recycled for reuse. In the prior art, a submerged arc welding trolley is used for submerged arc welding, which also has a flux recovery device. For example, the Chinese patent No. 03264506.6 discloses a recovery device for submerged arc welding flux, which can also automatically recover the remaining flux. It includes a suction hopper that provides a negative pressure for flux recovery and a storage hopper for storing flux. The flux storage hopper is connected to a flux recovery pipeline. Pipeline suction into storage hopper. This flux recovery device has a big defect. When the recovered flux is used for welding again, the sur...
