Slag separation tool for secondary recovery of submerged-arc welding flux

Abstract

The invention discloses a slag separation tool for secondary recovery of a submerged-arc welding flux. The slag separation tool comprises a box body (1) and is characterized in that the upper portion of the box body (1) is provided with a hopper (2), the lower portion of the box body (1) is provided with a receiving box (3), the receiving box (3) comprises a welding flux box (3.1) and a welding slag box (3.2), the welding flux box (3.1) and the welding slag box (3.2) are separated through a partition plate (4), the bottom of the hopper (2) is provided with a discharge outlet (2.1) which is located above the welding flux box (3.1), a screen plate (5) is arranged between the discharge outlet (2.1) and the welding flux box (3.1) in an inclined mode, the screen plate (5) is arranged to slide towards the welding slag box (3.2), and one end of the screen plate (5) is located under the discharge outlet (2.1). The defects that manual screening in the prior art is low in efficiency and large in labor consumption are overcome, and the slag separation tool has the advantages of being simple in structure, capable of saving the labor cost and high in welding flux separation purity.

Description

technical field [0001] The invention relates to a submerged arc welding flux separation device in the steel structure industry, in particular to a submerged arc welding flux secondary recovery slag agent separation tool. Background technique [0002] Submerged arc welding is an important welding method. It is widely used due to its inherent stable welding quality, high welding production efficiency, no arc light and less smoke and dust. Flux is an indispensable welding auxiliary material for submerged arc welding. Flux that has not yet melted needs to be recycled for reuse. Although the existing submerged arc welding is equipped with a semi-automatic flux recovery system, due to its own design defects, there is a gap between the welding machine positioning baffle and the components, resulting in part of the flux leaking during welding, which leads to the incomplete recovery of the flux. With the increase of the service life of the welding machine, the positioning baffle of ...

Problems solved by technology

Although the existing submerged arc welding is equipped with a semi-automatic flux recovery system, due to its own design defects, there is a gap between the welding machine positioning baffle and the components, resulting in part of the flux leaking during welding, which leads to the incomplete recovery of the flux. With the increase of the service life of the welding machine, the positioning baffle of the submerged arc welding machine will be deformed, and the problem of flux leakage will become more serious. Generally, steel structure manufacturers will recycle the flux from the perspective of production cost, but the flux will fall to the ground. It will be mixed with welding slag, and the welding slag and flux need to be separated during the secondary recovery of flux. At present, the separation of flux and welding slag is usually done by manual sieving, that is, one person shovels the material, and the other shakes the steel sieve to separate the flux from the welding slag. This method is inefficient and labor-intensive
