Circulating water rotary sealing assembly

The utility model discloses a circulating water rotary sealing assembly which comprises a bottom plate, a pipe is arranged at the top of the bottom plate, sealing rotary pipes and a filtering assembly are arranged at the two ends of the pipe, the filtering assembly is arranged at one end of the pipe, and the filtering assembly comprises an installation pipe. According to on-site use conditions, in the operation process of the centrifugal machine, a circulating water pipe is prone to distortion due to the fact that the rotating position is small, the pipe can rotate by 180 degrees when the centrifugal machine operates, the pipe cannot be distorted and deformed, the service life of the pipe is prolonged, and the failure rate of the centrifugal machine is reduced. The filter assembly is arranged between the pipe and the rotary sealing device close to one end of the centrifugal machine, when the filter plate needs to be replaced, only the moving rod needs to be pressed, the clamping block can move, and therefore
