In a mud pumping device that supplies compressed air to the mud pumping tank and pumps mud in the mud pumping tank from the mud discharge pipe to the mud pumping pipe, the compressed air is directed into the mud discharge pipe toward the mud pumping tank side. A mud pumping device characterized by being provided with air blowing means.

Claims

[Scope of Claim for Utility Model Registration] 1. A mud pumping tank having a pressure vessel structure to which mud is supplied, and a mud discharge pipe for discharging mud extending outward from the bottom of the mud pumping tank through a mud discharge valve. When the mud in the tank reaches a predetermined amount, compressed air is supplied to the mud pumping tank, the mud discharge valve is opened, and the mud in the tank is discharged from the mud discharge pipe. A mud pumping device for pumping mud into a mud feeding pipe, characterized in that an air pipe for injecting compressed air toward the tank is provided in the mud discharge pipe. 2 Compressed air is supplied to the air pipe before supplying compressed air for mud feeding into the tank and before opening the mud discharge valve, and after supplying compressed air for mud feeding into the tank. The mud pumping device according to claim 1, wherein the mud pumping device is controlled to be stopped after the mud discharge valve is opened.
