Double-storage bin submerged arc welding agent circulating device

Abstract

The invention provides a double-storage bin submerged arc welding agent circulating device which is applicable to the soldering flux recycle in the process of bead welding. The device is characterized in that a clapboard is welded in a welding agent barrel body, and the welding agent barrel body is divided into left and right storage bins with the same volume by the clapboard; the lower end of each storage bin is provided with a small rectangular material opening, and a material falling overturning plate is arranged at the lower end of the clapboard of the welding agent barrel body; air filter cores are fixed on the walls of the two storage bins with the same volume; side plates of filter core press covers are respectively welded with hose joints; the hose joints are respectively connected with inhaling hoses; the other ends of the inhaling hoses are respectively connected with two-port two-position electromagnetic valves; a third hose opening for inhaling three joint is connected with an air inlet of a high-pressure fan; and the two two-port two-position electromagnetic valves and the high-pressure fan are controlled, so that the two storage bins are respectively under the negative pressure status and the normal pressure status within the same time range; a negative pressure storage bin sucks the welding agent, and the welding agent falls off from a normal pressure storage bin, so that the transportation and the recycle of the welding agent can be realized; and the transportation, the recycle and the cycle operation process of the welding agent is more stable and reliable.

Description

technical field [0001] The invention relates to the technical field of automatic welding equipment, in particular to a submerged arc flux circulation device, which is a double-silo submerged arc flux circulation device. Background technique [0002] The submerged arc flux circulation device is a necessary configuration to ensure the long-distance welding continuity and flux utilization rate of the submerged arc automatic welding equipment. [0003] Suction type submerged arc flux circulation device is commonly used in submerged arc welding construction. The suction type submerged arc flux circulation device has a single flux barrel and single silo structure. The air in the flux barrel is sucked out by the fan to form a negative pressure in the flux barrel, and the flux is sucked into the flux barrel. The flux in the flux barrel overcomes the negative pressure in the barrel by its own gravity and falls to the welding position to realize the flux delivery and recovery cycle. ...

Problems solved by technology

Therefore, this kind of flux circulation device has poor stability and reliability of flux circulation, low flux recovery efficiency, and due to the high installation height of the flux barrel, the volume of the flux circulation device and corresponding welding equipment increases, which affects the flux circulation device and welding. Suitability of equipment, deficiencies that cause inconvenience to the installation, use and maintenance of flux circulation devices

In addition, a certain type of suction submerged arc flux circulation device is generally only designed for a certain density and particle size range of flux, and is designed under the condition of a certain flux height, so its flux application range is narrow
