Abstract

The invention discloses an on-line welding flux circulation recycle device for submerged arc welding. The on-line welding flux circulation recycle device comprises an upper hopper, wherein a negative-pressure device is arranged on the upper part of the upper hopper; a material suction opening is arranged on the upper hopper; the lower part of the upper hopper is connected with a lower hopper; and the lower hopper is used for providing airtightness for the equipment when the upper hopper discharges recycled welding flux. According to the on-line welding flux circulation recycle device, the recycle process is fully sealed; the recycle rate of the welding flux is high; and the impurity separation effect is good.

Description

Technical field [0001] The invention belongs to the field of steel pipe welding equipment, and particularly relates to an online flux recycling equipment for submerged arc welding. Background technique [0002] In the production process of submerged arc welding, flux, as a primary protective agent and secondary filler, consumes only about 10% during the welding process, and the rest can still be used. However, during the welding process, dust will inevitably be generated. The existence of a certain amount of dust will directly lead to the generation of welding pores and affect the quality of welding. Therefore, the remaining flux needs to be recycled and put into use after removing the dust. The recovery rate of the equipment in the prior art is very low, the recovery purity is very poor, and the recovery process is also very environmentally unfriendly, resulting in a very low utilization rate of the recovery equipment in actual production and no obvious effect. Summary of the ...
