The external clean water enters the discharge pipe 6 through the external pipe 8, and then enters the backflush pipe 701, and is transported to the feed pipe 2 through the backflush pipe 701 to backflush the blocked slurry inside the feed pipe 2.

[0032] The working principle of the environmentally friendly slurry pump blockage clearing device provided by the utility model is as follows:
