Claims

[Scope of Claim for Utility Model Registration] (1) At the top of the earth and mud water storage tank, an inlet for earth and mud water and an air exhaust pipe with an opening at the outer end are provided, and a jet nozzle is provided inside this air exhaust pipe, and a jet nozzle is provided inside the air exhaust pipe. A vacuum device using high-pressure air, characterized in that the outlet is directed toward the opening side of the air discharge pipe, the base end of the nozzle can be communicated with a high-pressure air source, and a discharge port for sand and sand is provided at the bottom of a sand and mud water storage tank. . (2) At the top of the earth and mud water storage tank, provide an inlet for earth and mud water and an air exhaust pipe with an opening at the outer end, and install a jet nozzle inside this air exhaust pipe so that the jet nozzle of the nozzle is connected to the opening side of the air exhaust pipe. At the same time, the base end of the nozzle can be communicated with a high-pressure air source, and a large earth and sand discharge port and a earth and mud water discharge port are provided at the bottom of the earth and mud water storage tank. A vacuum device using high-pressure air, characterized in that a flapper valve that closes when a storage tank is under negative pressure is provided, and the outside of the flapper valve is communicated with a submersible pump.
