[0001] The invention relates to the technical field of metal processing, in particular to an automatic slag removing device for a lead melting furnace. Background Art

[0002] During the lead product production process or the lead metal recycling process, the raw materials need to be heated and melted in a lead melting furnace for subsequent production. During the operation of the lead melting furnace, lead slag and other waste residues will be generated. They need to be removed before pouring and the slag removal work must be completed to ensure the quality of subsequent products.

[0003] Common lead melting furnaces produce waste slag during operation. Usually, long-handled scooping tools are used manually to remove the slag from the surface of the lead melting furnace. The slag removal process carries the risk of burns, and the high heat and smoke pose a serious health risk to employees.

[0004] Therefore, the above-mentioned lead melting furnace requires manual operation of long-handled scooping tools, which poses risks of burns during the slagging process. At the same time, the high heat and smoke pose a great threat to the health of employees. These problems need to be solved urgently to improve the usage scenario. Summary of the Invention

[0005] In order to overcome the common risks of burns during the slagging process of lead melting furnaces, and the problem that high heat and smoke cause great damage to employees' health.

[0006] The technical solution of the present invention is: an automatic slag removing device for a lead melting furnace, comprising a fixed plate, a support column installed at the lower end of the corner position of the fixed plate, a universal wheel provided at the bottom of the support column, a lifting assembly connected to the bottom of the fixed plate near the middle position, a mounting plate installed at the bottom of the lifting assembly, a rotating assembly provided on the mounting plate, a connecting pipe connected to the left end of the rotating assembly, a slag remover storage bucket installed on the top of the connecting pipe, a feeding assembly provided at the bottom of the connecting pipe, a connecting arm installed at the left end of the connecting pipe, and a slag scooping assembly connected to the lower end of the connecting arm.

[0007] Preferably, the entire device is pushed to the vicinity of the lead-melting furnace so that the connecting pipe and the connecting arm are located above the lead-melting furnace, and the slag remover is added through the feeding assembly. After a period of reaction, the lifting assembly is controlled to descend so that the lower end of the slag scooping assembly contacts the liquid surface of the lead-melting furnace, the rotating assembly is started, and the slag scooping work is completed by the slag scooping assembly. Thereafter, the lifting assembly is controlled to rise to complete the slag removal work without manual operation, thereby avoiding the impact on personnel health and reducing the danger of work. This solves the problem that common lead-melting furnaces produce waste slag during work, and usually the slag on the surface of the lead-melting furnace is removed by manually operating a long-handled scooping tool.
