[0002] Floating oil seal is a kind of dynamic seal. It has super sealing performance in harsh working environments such as coal powder, mud, sand, water vapor, etc. It is a compact mechanical seal, mainly used in low-speed and heavy-load situations. It has the advantages of wear resistance, automatic compensation after end face wear, reliable operation, simple structure, etc. It is widely used in coal mining machinery, such as scraper conveyor head (tail) sprocket assembly, roadheader loading mechanism and cantilever section, continuous coal mining machine left and right cutting drum and reducer, etc. The sealing surface of the floating oil seal needs to be polished during the production and processing process to ensure its flatness and fit.

[0003] In the prior art, a floating oil seal sealing surface grinding device with the authorization publication number CN211992440U includes a base and a column.

A first motor is fixedly installed in the interior of the first compartment through a mounting seat. The transmission shaft of the first motor is fixedly provided with a gear shaft. A feed port is opened at the top of one side of the second compartment. An exhaust fan is fixedly provided at the top of one side of the base. One end of the exhaust fan is fixedly connected to one end of the conduit through a transition pipe. This patent arranges an exhaust fan connected in series with the second motor at the top of one side of the base. When the second motor drives the grinding disc to grind the sealing surface of the floating oil seal, the exhaust fan can extract the waste generated during grinding and discharge the waste into the second compartment through the feed port.
