Smoke exhaust device matched with submerged arc abrasion-resistant surfacing welding machine

Abstract

The invention discloses a smoke exhaust device matched with a submerged arc abrasion-resistant surfacing welding machine. The smoke exhaust device comprises a smoke exhaust hood fixed to a transversemoving support of the submerged arc abrasion-resistant surfacing welding machine. The smoke exhaust hood is arranged outside an electric welding head of the submerged arc abrasion-resistant surfacingwelding machine in a surrounding mode. A smoke exhaust port is formed in the side wall of the smoke exhaust hood, and the smoke exhaust port of the smoke exhaust hood is communicated with a horizontalsmoke exhaust pipe in a butt joint mode. The horizontal smoke exhaust pipe is communicated with a vertical smoke exhaust pipe. A discharge port is formed in the bottom of the outlet end of the horizontal smoke exhaust pipe, a discharge hopper is arranged at the discharge port, and a discharge valve is arranged at a bottom outlet of the discharge hopper. A welding slag scraping mechanism is arranged on the horizontal smoke exhaust pipe, and a plurality of partition plates arranged in a staggered mode are fixed to the inner wall of the vertical smoke exhaust pipe from bottom to top. A zigzag gas flow channel is formed in the vertical smoke exhaust pipe through the partition plates, an outlet of the vertical smoke exhaust pipe is communicated with a filter through a smoke exhaust hose, and the filter is communicated with a dust removal fan. The smoke exhaust pipe has the advantages that the smoke exhaust pipe is not prone to being blocked in the using process, and using is made more convenient.

Description

technical field [0001] The invention relates to the technical field of surface processing equipment for flat metal workpieces, in particular to a smoke exhaust device matched with a submerged arc wear-resistant surfacing welding machine. Background technique [0002] Submerged arc wear-resistant surfacing welding machine is a commonly used flat metal working surface processing equipment, which is mainly used to process a layer of surfacing on the surface of flat metal workpieces. The structure of the submerged arc wear-resistant surfacing welding machine currently used is as follows: it includes a frame, on which a platform for placing flat metal workpieces is provided, and on the left and right sides of the platform, there are respectively provided with first guide rails running forward and backward. , on the first guide rail, a vertical movement bracket is slidably arranged, and the longitudinal movement support can move forward and backward along the first guide rail unde...

AI Technical Summary

Problems solved by technology

The disadvantages of the currently used smoke exhaust device are: due to the large amount of welding slag particles contained in the dense smoke, the smoke exhaust hose is easily blocked by welding slag particles during the smoke exhaust process, which is inconvenient to use
