Description

Technical Field

[0001] The utility model relates to the technical field of anode carbon block production, in particular to a floating tool holder for cleaning the surface of carbon blocks. Background Technique

[0002] During the baking process of carbon blocks, some rubber particles are filled to protect the carbon blocks.

[0032] As Figure 6As shown, the first hinge base 601 includes two first side plates 6011, which are welded to the first bottom plate 6017. The first rotating shaft 6012 passes through the two first side plates 6011.

[0034] During operation, the floating oil cylinders 6 on the floating tool holders on both sides of the carbon block are fully extended. The rotating hinge base 7 supports the tool holder 8 to rotate around the position of the second rotating shaft 705. At this time, the floating oil cylinders 6 are in a pressure-holding state to ensure that when the carbon block passes through the channel, the scraping knife 807 always exerts a squeezing force on the surface of the carbon block. Through the generated frictional force, the rubber particles and scum on the surface of the carbon block are scraped off. To ensure the smooth passage of the carbon block, when the carbon block is stuck or jammed, the floating oil cylinders 6 will fully retract, and an external force is applied to adjust the carbon block to ensure the normal operation of the equipment.

[0035] Before operation, by adjusting the second bolt 810, the compression spring 811 has a certain pre-tightening force, so that the scraping knife 807 has a pre-tightening pressure on the carbon block, making it easier to scrape off the rubber particles and scum. During operation, the second hinge base 803 and the compression spring seat 812 will be adjusted according to the size of the carbon block and the pressing amount of the scraping knife 807 on the carbon block by the first connecting bolt 815, the second connecting bolt 814, the first pressing bolt 801, and the second pressing bolt 813 connected to the tool holder 8.
