The brand is determined by the steel type of the object to be welded, and mixing different types of fluxes has a negative effect on welding performance. Therefore, every time the steel type of the workpiece is changed, it is necessary to completely remove the used flux and then introduce new flux into the supply hopper.

させても排出は不可能であつた。 FIG. 1 is a longitudinal sectional view of a screw conveyor type flux supply device. To explain the operation, the flux in the hopper 1 is moved forward by a screw 3 driven by a motor 2.
After passing through the supply pipe 4, it is sprayed at the welding position from the supply port 5. The flux in the hopper 1 is sequentially discharged from the rear of the hopper in approximately proportion to the screw rotation speed, but the flux remaining in the gap 8 between the screw 3 and the hopper 1 cannot be discharged by the rotation of the screw 3. However, in a submerged arc welding device using a screw conveyor-type flux automatic supply device, a certain distance is required between the outer diameter surface of the screw conveyor and the hopper bottom 4 due to the nature of the screw conveyor. The flux remaining in this gap could not be discharged no matter how much the screw was rotated.

し、残留フラツクスを吸引する。 FIG. 2 is a longitudinal sectional view of one embodiment of the device of the present invention, and FIG. 3 is a sectional view taken along line AA in FIG. In the figure, reference numeral 6 denotes an air barrier sheet according to the present invention.As shown in FIG. When removing, the sheet 6 is lowered to cover the screw conveyor from above to block air. Then, a recovery hose of a flux recovery machine (not shown) installed separately is connected to the supply port 5, and the residual flux is sucked out.

下部に残留しているフラツクスは、空気と共に吹
き飛ばされ、フラツクス回収機に回収される。 Due to the negative pressure caused by the suction of the flux collector, the sheet 6 comes into close contact with the screw 3 and the bottom surface 7 of the hopper, making the blocking of intruding air even more effective.
Suction the air vigorously. The sucked air passes through the space between the sheet 6 and the screw 3 at high speed,
After passing through the supply pipe 4, the flux enters the flux recovery machine through the supply port 5. Due to this passing wind pressure, the flux remaining at the bottom of the screw is blown away together with the air and collected by the flux collection machine.

る。 As explained above, the present invention is a device that can easily and completely remove residual flux by installing a sheet of soft material that temporarily blocks air entering from the outer periphery of the screw in the flux supply hopper. When replacing the flux, it is possible to completely replace it with another flux, and it provides a better effect in terms of welding quality.
