Description

Technical Field

[0001] The invention relates to a robot workstation structure for automatically cleaning phosphorus pig iron blocks for electrolytic aluminum anodes, belonging to the field of electrolytic aluminum production tools. Background Art

[0002] In the electrolytic aluminum production process, carbon anodes (electrode blocks are also called carbon blocks) need to be cast before use. By casting phosphorus pig iron, the carbon anode body is connected to the auxiliary facilities as a whole, which is convenient for use. Because the anode surface is adhered to phosphorus pig iron blocks after casting, it needs to be cleaned to prevent phosphorus pig iron from entering the tank and affecting the quality of the original aluminum liquid.

[0003] During cleaning, the carbon anode is usually struck manually with a heavy hammer, which is inefficient and the temperature of the carbon anode body just after casting is relatively high, and manual cleaning is also unsafe.

[0004] That is, a robot workstation structure for automatically cleaning anode phosphorus pig iron blocks is needed, which can automatically clean the phosphorus pig iron blocks to improve efficiency and safety. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a robot workstation structure for automatically cleaning phosphorus pig iron blocks, which can automatically clean the phosphorus pig iron blocks, improve efficiency and safety, and overcome the shortcomings of the prior art.

In this process, the main control cabinet plays the role of the main control; the carbon block fixing device can fix the carbon blocks to facilitate the cleaning of the mechanical arm; the carbon block guiding and detecting device plays the role of detecting whether there are carbon blocks and guiding the detected carbon blocks to the carbon block fixing device.
