Automatic flange welding device

Abstract

The invention discloses an automatic flange welding device, and belongs to the technical field of flange welding. The device comprises a device body, a drain valve pipe and a welding gun, an observation window is installed above the outer surface of the device body, an operation table is installed below the observation window, an in-out window is formed in one side of the device body, a bearing plate is fixed to one side of the in-out window, when the welding gun conducts welding, an exhaust fan runs and draws air through an exhaust pipe, so that multiple ash extraction heads penetrating through the bottom of a centralized pipe extract ashes simultaneously, due to the fact that the ends, away from the centralized pipe, of the ash extraction heads are arranged towards the direction of the welding gun and located above a conveying belt, smoke dust is extracted away through the ash extraction heads, the centralized pipe and the exhaust pipe in sequence and then injected into a water tankthrough an exhaust duct, and the smoke dust is precipitated by clean water in the water tank. Excessive air is exhausted through an exhaust port, and the settled dust is concentrated by a filter screen, so that the smoke dust is treated.

Description

technical field [0001] The invention relates to the technical field of flange welding, in particular to an automatic flange welding device. Background technique [0002] Flange is otherwise known as flange flange or flange. Flanges are parts that are connected to each other between shafts and are used for connection between pipe ends; they are also useful for flanges on equipment inlets and outlets, And can be used as connection between two equipments, example reducer flanges. Flange connection or flange joint refers back to the detachable connection of flange, Gasket and bolt as a team of combined sealing structure. Pipe flange refers back to the flange used for piping in the pipeline installation, And used on the equipment refers to the inlet and outlet flange of the equipment. There are holes in the flange, and the bolts tightly connect the two flanges. The flanges are sealed with gaskets. Flanges are divided into threaded (screw connection) flanges, welding flanges a...
