Slurry deposition prevention device for drilling operation

The utility model discloses a mud deposition prevention device for drilling operation. The mud deposition prevention device comprises a mud tank, a mud pump and an electric cabinet, the mud tank is divided into an upper part and a lower part; a slurry outlet is formed in the lower portion of the slurry tank and connected with an input pipeline of a slurry pump, and an output port of the slurry pump is connected with a flushing pipeline. The flushing pipeline extends into the mud tank from the outside of the mud tank, and a flushing hole is formed in the flushing pipeline in the mud tank; a liquid level meter is further arranged on the mud tank and used for detecting the height of the liquid level of mud in the mud tank. According to the utility model, slurry circulation is formed by slurry; and the slurry is homogenized in the circulating process, so that the safety of the drilling process is guaranteed. In addition, in the circulation process, the flushing pipeline flushes the interior of the mud tank, solid
