Description

Technical Field

[0001] The utility model relates to the technical field of automatic feeding of submerged arc welding flux, in particular to an automatic feeding device for submerged arc welding flux. Background Art

[0002] Sintered flux refers to a high-quality, efficient, energy-saving and environmentally friendly flux. It refers to the preparation of wet material flux, which is processed into the required particles and calcined at high temperature to form fine particles, that is, sintered flux. This flux is smokeless, odorless, arc-free and spatter-free during welding. The production process is environmentally friendly, has low energy consumption, and fully utilizes raw materials. It complies with national industrial development policies. Sintered flux is made by dry-mixing multiple mineral powder raw materials in a certain ratio and finally sintering.

[0003] The flux needs to be sintered in a calcining furnace during sintering. The raw materials of the flux are mostly in powder form, which becomes granular after sintering. Raw materials need to be continuously added during sintering. The sintering furnace usually has an overflow hole. If too much raw material is added, it will overflow. The overflowed raw materials need to be picked up by personnel using a trolley and transported to the raw material adding area for further addition. The back-and-forth transportation is troublesome and requires additional personnel to operate. For this reason, we provide a submerged arc flux automatic feeding device to solve the above problems.

The motor 5 drives the material-diverting plate 17 to rotate through the movable plate 6 and the linkage mechanism 7, and then diverts the collected material overflowing from the bottom of the material collecting shell 8 to the side position, and then uses the first fan 3 provided on the support frame 2 to introduce airflow into the chamber 14 opened inside the material collecting shell 8 through the fan pipe 15 of the first fan 3. The airflow will move the material upward along the inner wall of the chamber 14 in the material collecting shell 8, and the second fan 4 will also use the above-mentioned method to continue to blow the material upward. After being blown up, the material is sent to the top of the material collecting shell 8 through the inclination angle formed between the guide block 16 inside the material collecting shell 8 and the stopper 13 fixed on the surface of the calcining furnace 9, and the material gathered at the top of the chamber 14 is replenished into the calcining furnace 9 through the feeding hole 12 through the inclination of the stopper 13.
