High-speed rail waste liquid circulating device

The utility model relates to the technical field of circulating devices, and discloses a high-speed rail waste liquid circulating device. The high-speed rail waste liquid circulating device comprises a filtering chamber, a filtering plate and a rotating shaft, a water inlet pipe is welded to the top of the filtering chamber, the filtering plate is connected into the filtering chamber through bolts, large impurities in waste water can be filtered out through the filtering plate, and the waste water without carrying the large impurities can enter a water collecting tank through a conveying pipe; when the wastewater in the water collecting tank is accumulated to a certain degree, a solution for decomposing grease and a cleaning agent are pumped into the material pipe through an external pump body, a rotating motor is started to drive a rotating shaft to rotate, so that a stirring rod fully stirs and mixes the wastewater and the solution, and after the wastewater and the solution are mixed, an electromagnetic val
